## Background
CROSS REFERENCE TO RELATED APPLICATIONS
The present application is a divisional of U.S. Non-Provisional application Ser. No. 14/633,082 filed Feb. 26, 2015, which is incorporated herein by reference in its entirety for all purposes.


TECHNICAL FIELD
Generally, the present disclosure relates to material separation.
BACKGROUND
In the present disclosure, where a document, an act and/or an item of knowledge is referred to and/or discussed, then such reference and/or discussion is not an admission that the document, the act and/or the item of knowledge and/or any combination thereof was at the priority date, publicly available, known to the public, part of common general knowledge and/or otherwise constitutes prior art under the applicable statutory provisions; and/or is known to be relevant to an attempt to solve any problem with which the present disclosure is concerned with. Further, nothing is disclaimed.
Sugarcane plants comprise stems, leaves extending from the stems, and top portions extending from the stems, usually above the leaves. The sugarcane plants are typically processed for sugar production in various stages, such as a harvesting stage and a milling stage. However, at least during such stages various inefficiencies exist.
During the harvesting stage, sugarcane harvesting machines harvest the sugarcane plants such that the stems are cut into billets, such as about six inches long, and the leaves and the top portions are separated from the stems, such as via cutting. Such type of processing is usually energy inefficient. Further, when the leaves and the top portions are separated from the stems, the leaves and the stems form an undesired biomass called field trash, which is naturally blown back into the fields from which the plants were originally harvested. Such blowback process also blows some of the billets back into the fields, which creates a sugar loss of as much as 8% per acre of sugarcane plant harvested. Although some of that blown back biomass is eventually extracted from the fields, such extraction process is usually inefficient, in some cases with about 20% of the field trash being left in the fields with the blown back billets. In addition, the field trash is frequently burned in the fields, which creates an environmental hazard or a safety hazard. Also, as the field trash becomes mixed with the billets in the fields, sugarcane trash is formed. Therefore, when the harvesting machines harvest the sugarcane plants, the harvesting machines end up picking up dirt, which is called ash, that gets mixed in with the sugarcane trash. Such processing is inefficient.
During the milling stage, the sugarcane plants are processed at a sugarcane mill such that sugar is extracted from the stems, i.e. the billets. However, the leaves and the top portions remain unprocessed due to their lack of any substantially extractable sugar, which is inefficient. Also, raw processing material delivered to the mill often contains about 80% sugarcane billets, about 18% sugarcane trash, and about 2% ash on a weight basis, when extracted under optimal weather conditions. However, when such material is extracted under suboptimal weather conditions, the ash can be about 10% of the raw material by weight, which is inefficient. Furthermore, the sugarcane trash and the ash can impede sugar production for various reasons. First, the sugarcane trash can reduce the mill's crushing capacity by about 20%, which can increase the mill's grinding season by about 20%. Second, the sugarcane trash can contain a substantial amount of starches, which, if not properly extracted, can degrade sugar output at the mill. Third, the ash, which is often substantially silica or field dirt, can create a lot of wear and tear to the mill's machinery. Resultantly, the ash needs to be filtered out during the sugar making process and such filtration process creates a loss of about 3% in the mill's sugar yield.
Accordingly, there is a need to address at least one of such inefficiencies.

DETAILED DESCRIPTION
The present disclosure is now described more fully with reference to the accompanying drawings, in which example embodiments of the present disclosure are shown. The present disclosure may, however, be embodied in many different forms and should not be construed as necessarily being limited to the example embodiments disclosed herein. Rather, these example embodiments are provided so that the present disclosure is thorough and complete, and fully conveys the concepts of the present disclosure to those skilled in the relevant art.
Features described with respect to certain example embodiments may be combined and sub-combined in and/or with various other example embodiments. Also, different aspects and/or elements of example embodiments, as disclosed herein, may be combined and sub-combined in a similar manner as well. Further, some example embodiments, whether individually and/or collectively, may be components of a larger system, wherein other procedures may take precedence over and/or otherwise modify their application. Additionally, a number of steps may be required before, after, and/or concurrently with example embodiments, as disclosed herein. Note that any and/or all methods and/or processes, at least as disclosed herein, can be at least partially performed via at least one entity in any manner.
The terminology used herein can imply direct or indirect, full or partial, temporary or permanent, action or inaction. For example, when an element is referred to as being “on,” “connected” or “coupled” to another element, then the element can be directly on, connected or coupled to the other element and/or intervening elements can be present, including indirect and/or direct variants. In contrast, when an element is referred to as being “directly connected” or “directly coupled” to another element, there are no intervening elements present.
Although the terms first, second, etc. can be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not necessarily be limited by such terms. These terms are used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer, or section discussed below could be termed a second element, component, region, layer, or section without departing from the teachings of the present disclosure.
The terminology used herein is for describing particular example embodiments and is not intended to be necessarily limiting of the present disclosure. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “includes” and/or “comprising,” “including” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence and/or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances.
Example embodiments of the present disclosure are described herein with reference to illustrations of idealized embodiments (and intermediate structures) of the present disclosure. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, the example embodiments of the present disclosure should not be construed as necessarily limited to the particular shapes of regions illustrated herein, but are to include deviations in shapes that result, for example, from manufacturing.

Any and/or all elements, as disclosed herein, can be manufactured via any manufacturing processes, whether additive manufacturing, subtractive manufacturing, and/or other any other types of manufacturing. For example, some manufacturing processes include three dimensional (3D) printing, laser cutting, computer numerical control routing, milling, pressing, stamping, vacuum forming, hydroforming, injection molding, lithography, and so forth.
Any and/or all elements, as disclosed herein, can be and/or include, whether partially and/or fully, a solid, including a metal, a mineral, an amorphous material, a ceramic, a glass ceramic, an organic solid, such as wood and/or a polymer, such as rubber, a composite material, a semiconductor, a nanomaterial, a biomaterial and/or any combinations thereof. Any and/or all elements, as disclosed herein, can be and/or include, whether partially and/or fully, a coating, including an informational coating, such as ink, an adhesive coating, a melt-adhesive coating, such as vacuum seal and/or heat seal, a release coating, such as tape liner, a low surface energy coating, an optical coating, such as for tint, color, hue, saturation, tone, shade, transparency, translucency, opaqueness, luminescence, reflection, phosphorescence, anti-reflection and/or holography, a photo-sensitive coating, an electronic and/or thermal property coating, such as for passivity, insulation, resistance or conduction, a magnetic coating, a water-resistant and/or waterproof coating, a scent coating and/or any combinations thereof. Any and/or all elements, as disclosed herein, can be rigid, flexible, and/or any other combinations thereof. Any and/or all elements, as disclosed herein, can be identical and/or different from each other in material, shape, size, color and/or any measurable dimension, such as length, width, height, depth, area, orientation, perimeter, volume, breadth, density, temperature, resistance, and so forth.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and should not be interpreted in an idealized and/or overly formal sense unless expressly so defined herein.
Furthermore, relative terms such as “below,” “lower,” “above,” and “upper” can be used herein to describe one element's relationship to another element as illustrated in the accompanying drawings. Such relative terms are intended to encompass different orientations of illustrated technologies in addition to the orientation depicted in the accompanying drawings. For example, if a device in the accompanying drawings were turned over, then the elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. Similarly, if the device in one of the figures were turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. Therefore, the example terms “below” and “lower” can encompass both an orientation of above and below.
As used herein, the term “about” and/or “substantially” refers to a +/−10% variation from the nominal value/term. Such variation is always included in any given value/term provided herein, whether or not such variation is specifically referred thereto.
If any disclosures are incorporated herein by reference and such disclosures conflict in part and/or in whole with the present disclosure, then to the extent of conflict, and/or broader disclosure, and/or broader definition of terms, the present disclosure controls. If such disclosures conflict in part and/or in whole with one another, then to the extent of conflict, the later-dated disclosure controls.

A system 100, which is useful for detrashing, comprises a control area 200, an air source assembly 300, a material separation assembly 400, a ductwork assembly 500, a tower assembly 600, and a material processing assembly 700. The system 100 or at least one of the control area 200, the air source assembly 300, the separation assembly 400, the ductwork assembly 500, the tower assembly 600, and the material processing assembly 700 is positioned at least partially outdoors, such as on a ground surface, whether having a flat terrain or a rugged terrain, whether urban or countryside, such as in a field. However, in other embodiments, the system 100 or at least one of the control area 200, the air source assembly 300, the separation assembly 400, the ductwork assembly 500, the tower assembly 600, and the material processing assembly 700 is positioned at least partially indoors, such as in a warehouse or a tent, including underneath a dome. Further, in yet other embodiments, the system 100 or at least one of the control area 200, the air source assembly 300, the separation assembly 400, the ductwork assembly 500, the tower assembly 600, and the material processing assembly 700 is positioned at least partially underground, such as in a bunker, a basement, or a garage.
The system 100 or at least two of the control area 200, the air source assembly 300, the separation assembly 400, the ductwork assembly 500, the tower assembly 600, and the material processing assembly 700 are positioned in one locale. However, in other embodiments, none of the control area 200, the air source assembly 300, the separation assembly 400, the ductwork assembly 500, the tower assembly 600, and the material processing assembly 700 are positioned in one locale.
The system 100 or at least one of the control area 200, the air source assembly 300, the separation assembly 400, the ductwork assembly 500, the tower assembly 600, and the material processing assembly 700 is stationary, such as installed onto a ground surface, whether having a flat terrain or a rugged terrain, whether urban or countryside, such as in a field. However, in other embodiments, the system 100 or at least one of the control area 200, the air source assembly 300, the separation assembly 400, the ductwork assembly 500, the tower assembly 600, and the material processing assembly 700 is mobile, such as based on a vehicle, whether land, aerial, or marine.
The control area 200, the air source assembly 300, and the separation assembly 400 are in relative proximal positioning to each other, i.e., positioned in a cluster, with respect to the separation assembly 400 being in relative distal positioning to the material processing assembly 700, as spanned by the ductwork assembly 500 supported via the tower assembly 600. However, in other embodiments, such positioning can vary in any manner, such as the material processing assembly 700 being proximally positioned within a cluster comprising the control area 200, the air source assembly 300, and the separation assembly 400. In such configuration, the ductwork assembly 500 can be shaped accordingly, such as in a U-shape.
The system 100 or at least two of the control area 200, the air source assembly 300, the separation assembly 400, the ductwork assembly 500, the tower assembly 600, and the material processing assembly 700 are positioned along one plane, such as a horizontal plane. However, in other embodiments, none of the control area 200, the air source assembly 300, the separation assembly 400, the ductwork assembly 500, the tower assembly 600, and material processing assembly 700 are positioned along one plane, such as the control area 200, the air source assembly 300, the separation assembly 400, the ductwork assembly 500, the tower assembly 600, and the material processing assembly 700 being positioned on different horizontal planes, such as one being elevated higher than another or inclined.
The separation assembly 400 comprises an input conveyor section 402. The system 100 is operably coupled to an input material section 800, which comprises a motorized conveyor 802 conveying material, such as sugarcane trash, in a direction perpendicular to the input conveyor section 402, although other conveyance directions are possible, such as diagonal. The conveyor 802 can transfer such material onto the input conveyor section 402. For example, the conveyor 802 can be selectively adjustable to convey such material onto the input conveyor section 402. Whether additionally or alternatively, the input conveyor section 402 can also be selectively adjustable to receive such material from the conveyor 802. Such types of selective adjustment can be based at least in part on a manual input, such as via a lever, a button, a keyboard, or some other input device. Whether additionally or alternatively, the selective adjustment can also be based at least in part on an automatic input, such as via a computer program based at least in part on a sensor input, such as via heuristics. For example, such sensor input can be based at least in part on a detection of foreign matter in the material being conveyed on the conveyor 802. Some characteristics of such adjustment comprise at least one of a positional adjustment, a directional adjustment, and a speed adjustment.
The input material section 800 is positioned at least partially outdoors, such as on a ground surface, whether having a flat terrain or a rugged terrain, whether urban or countryside, such as in a field. However, in other embodiments, the input material section 800 is positioned at least partially indoors, such as in a warehouse or a tent, including underneath a dome. Further, in yet other embodiments, the input material section 800 is positioned at least partially underground, such as in a bunker, a basement, or a garage. The input material section 800 is one locale with the system 100 or at least one of the control area 200, the air source assembly 300, the separation assembly 400, the ductwork assembly 500, the tower assembly 600, and the material processing assembly 700. The input material section 800 is stationary, such as installed onto a ground surface, whether having a flat terrain or a rugged terrain, whether urban or countryside, such as a field. However, in other embodiments, the input material section 800 is mobile, such as based on a vehicle, whether land, aerial, or marine.
The system 100 is operably coupled to an output material section 900, which comprises a conveyor 902 conveying material, such as sugarcane billets, as separated via the separation assembly 400. The conveyor 902 comprises a plurality of motorized rotary shredders 904 serially positioned along the conveyor 902, above the conveyor 902. For example, at least one of the motorized rotary shredders 904 can comprise a knife mounted on a shaft extending along a horizontal plane perpendicular to a conveying direction of the conveyor 902, where the knife rotates about the shaft to shred the material as the material passes. In other embodiments, the motorized rotary shredders 904 are positioned in parallel along the conveyor 902. The knife comprises a blade, whether with a uniform edge, such as rectilinear edge, an arcuate edge, or a circular edge, or a varying edge, such as a serrated edge. In other embodiments, at least one of the motorized rotary shredders 904 comprises an auger with a helical blade, whether rotating about an axis perpendicular to the conveyor 902, an axis diagonal to the conveyor 902, or an axis parallel to the conveyor 902. The output material section 900 can comprise a washing station for washing the material, whether before, during, or after the shredding.
The output material section 900 is positioned at least partially outdoors, such as on a ground surface, whether having a flat terrain or a rugged terrain, whether urban or countryside, such as in a field. However, in other embodiments, the output material section 900 is positioned at least partially indoors, such as in a warehouse or a tent, including underneath a dome. Further, in yet other embodiments, the output material section 900 is positioned at least partially underground, such as in a bunker, a basement, or a garage. The output material section 900 is one locale with the system 100 or at least one of the control area 200, the air source assembly 300, the separation assembly 400, the ductwork assembly 500, the tower assembly 600, the material processing assembly 700, and the input material section 800. The output material section 900 is stationary, such as installed onto a ground surface, whether having a flat terrain or a rugged terrain, whether urban or countryside, such as in a field. However, in other embodiments, the output material section 900 is mobile, such as based on a vehicle, whether land, aerial, or marine.
The output material section 900 conveys shredded material to a shredded material processing section 1000, which comprises a water mixing station and a crushing station downstream from the water mixing station. The shredded material is repeatedly mixed with the water via the water mixing station, such as via a set of sprinklers sprinkling the shredded material with water in a periodic manner or a continuous manner. The crushing station comprises a set of rollers configured to crush the washed shredded material. For example, at least one of the rollers can comprise a circular disc mounted on a shaft extending along a horizontal plane perpendicular to a conveying direction of the shredded material, where the disc rotates about the shaft to crush the shredded material as the material passes underneath, such as via rolling over the material. The rollers can be serially positioned or positioned in parallel. Such crushing results in a juice, such as sucrose juice when the material comprises sugarcane billets. The juice is collected for further processing, dependent on the material.
The shredded material processing section 1000 is positioned at least partially outdoors, such as on a ground surface, whether having a flat terrain or a rugged terrain, whether urban or countryside, such as in a field. However, in other embodiments, the shredded material processing section 1000 is positioned at least partially indoors, such as in a warehouse or a tent, including underneath a dome. Further, in yet other embodiments, the shredded material processing section 1000 is positioned at least partially underground, such as in a bunker, a basement, or a garage. The shredded material processing section 1000 is one locale with the system 100 or at least one of the control area 200, the air source assembly 300, the separation assembly 400, the ductwork assembly 500, the tower assembly 600, the material processing assembly 700, the input material section 800, and the output material section 900. The shredded material processing section 1000 is stationary, such as installed onto a ground surface, whether having a flat terrain or a rugged terrain, whether urban or countryside, such as a field. However, in other embodiments, the shredded material processing section 1000 is mobile, such as based on a vehicle, whether land, aerial, or marine.
A mill 1100 is positioned in one locale with the system 100 or at least one of the control area 200, the air source assembly 300, the separation assembly 400, the ductwork assembly 500, the tower assembly 600, the material processing assembly 700, the input material section 800, the output material section 900, and the material processing section 1000. However, in other embodiments, such positioning can vary in any combinatory manner, such as the system 100 and the mill 1100 being positioned in different locales. Note that the system 100 and the mill 1100 can be operably coupled to each other, whether directly or indirectly. Also, note that at leas one of the input material section 800, the output material section 900, and the material processing section 1000 can be operably coupled to the mill 1100. The mill 1100 is positioned at least partially outdoors, such as on a ground surface, whether having a flat terrain or a rugged terrain, whether urban or countryside, such as in a field. However, in other embodiments, the mill 1100 is positioned at least partially indoors, such as in a warehouse or a tent, including underneath a dome.

FIG. 5 shows a lateral profile view of an example embodiment of a detrashing system according to the present disclosure. FIG. 6 shows a longitudinal profile view of an example embodiment of a separation assembly according to the present disclosure. Some elements of these figures are described above.

The air source assembly 300 comprises a tower frame 302 and a cyclone separator 304 coupled thereto, such as via fastening, mating, interlocking, adhering, clamping, nesting, adhering, magnetizing, or other coupling methods. The frame 302 comprises a lattice, but can be configured without the lattice as well. The frame 302 is shaped in a tubular rectangular manner, but in other embodiments, the frame 302 can be shaped in other manners, such as a cone, a pyramid, a hyperboloid, a T-shape, a Y-shape, or an H-shape, whether in original shape or inverted.
The frame 302 hosts the separator 304, which is configured to perform cyclonic separation via removing a plurality of particulates from at least one of air and gas through vortex separation, such as via rotational effects or gravity. The cyclonic separation can be with a filter or without a filter. The separator 304 receives dirty forced air from a boiler, which can be stationed on a sugarcane mill. For example, such dirt comprises ash. The dirty forced air can be between about 34 degrees and about 212 degrees on a Fahrenheit scale. For example, the dirty forced air can be waste heat from the sugar mill. Note that in some embodiments, the forced air is not dirty or is not within such temperature range. For example, such air can be provided via an air compressor or from a compressed air source.
The separator 304 comprises an inlet duct, a cyclone cylindrical body in fluid communication with the inlet duct, and a conical section 308 in fluid communication with the cyclone body at a first end of the cyclone body. Note that such configuration can be unitary or an assembly, such as via fastening, mating, interlocking, adhering, clamping, nesting, adhering, magnetizing, or other coupling methods. The inlet duct extends along a horizontal plane in an arcuate manner. The cylindrical body comprises a sidewall through which the inlet duct is in fluid communication with the cylindrical body, above the conical section 308. The separator 304 comprises a rectilinear tubular outlet duct in fluid communication with the cyclone body at a second end of the cylindrical body opposing the first end. The conical section 308 comprises an open end opposite from the second end along a vertical axis on which the first end and the second end are positioned. Note that the separator 304 can comprise one or more ducts in fluid communication with each other, whether directly or indirectly, such as via an interconnect duct.
The assembly 300 further comprises a forced air exit duct 306 in fluid communication with the separator 304 via the rectilinear outlet duct. The duct 306 is also in fluid communication with the air supply section 408. The duct 306 can be flexible or rigid. The duct 306 can extend longitudinally in any length, such as twenty feet, or can have any longitudinal shape, such as rectilinear, arcuate, sinusoidal, or any other shapes. The duct 306 can have any cross-sectional shape, such as circular, oval, triangular or any other polygonal shape, such as a square, a rectangle, a pentagon, a hexagon, an octagon, and so forth. The duct 306 can be thermally insulated, such as via a thermally insulating jacket mounted thereon, for instance a polyurethane jacket.
As the dirty hot air is input via the inlet duct into the cylindrical body, such as in a laterally originating path, the dirty hot air begins to flow within the cylindrical body in a downward helical pattern from a top portion of the cylindrical body, i.e. from the outlet duct, toward the open end of the conical section 308 before exiting the cylindrical body in a straight upward stream path through a center of the helical pattern via the rectilinear outlet duct along the vertical axis along which the first end and the second end are positioned. However, when the dirty hot air enters the conical section 308, the dirt in the hot forced air has excessive inertia to follow a tight curve flow of the hot air upward toward the rectilinear outlet duct, such as due to size or density. Resultantly, the dirt strikes an inner surface of the conical section 308. Since a rotational path is reduced in the conical section 308, due to a tapering volume of the conical section 308, such striking action causes the dirt to separate into a set of small particles, which are output through the open end of the conical section 308 based at least in part on natural gravity. Accordingly, the dirt exits the conical section 308 and can fall onto a conveyor, a cart or a vehicle, which can be prepositioned in advance, or onto a ground surface, such as to form a pile of dirt on the ground surface. The air, which is effectively substantially free from the dirt, exits the separator 304 via the rectilinear outlet duct and enters the forced air exit duct 306, which conducts such air to the air supply section 408 for use by the dryer section 406 and the separation section 410.
FIG. 7 shows a lateral profile view of an example embodiment of a material processing assembly according to the present disclosure. FIG. 8 shows a longitudinal profile view of an example embodiment of a separation assembly and a material processing assembly operably coupled to each other according to the present disclosure.

Thus, same reference characters identify identical and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication.
The material processing assembly 700 comprises a tower frame 702 resting on a ground surface, a cyclone separator 704 hosted via the frame 702, and a chute 708 hosted via the frame 702. Such types of hosting can be via fastening, mating, interlocking, adhering, clamping, nesting, adhering, magnetizing, or other coupling methods.
The frame 702 comprises a lattice, but can be configured without the lattice as well. The frame 702 is shaped in a tubular rectangular manner, but in other embodiments, the frame 702 can be shaped in in other manners, such as a cone, a pyramid, a hyperboloid, a T-shape, a Y-shape, or an H-shape, whether in original shape or inverted.
The separator 704 is configured to perform cyclonic separation via removing a plurality of particulates from at least one of air and gas through vortex separation, such as via rotational effects or gravity. The cyclonic separation can be with a filter or without a filter. The separator 704 receives dirty air from the ductwork assembly 500, which conducts the material from the separation assembly 400. For example, such dirt comprises the leaves or the top portions separated from the sugarcane stems, i.e. billets, via the separation assembly 400. The dirty air can be between about 34 degrees and about 212 degrees on a Fahrenheit scale. Note that in some embodiments, the air is not dirty or is not within such temperature range. Note that the separator 704 operates in reverse of separator 304, such as the separator 704 operates in a reverse cyclonic separation process and the separator 304 operates in a cyclonic separation process.
The separator 704 comprises an inlet duct, a cyclone cylindrical body in fluid communication with the inlet duct, and a conical section 706 in fluid communication with the cyclone body at a first end of the cyclone body. Note that such configuration can be unitary or an assembly, such as via fastening, mating, interlocking, adhering, clamping, nesting, adhering, magnetizing, or other coupling methods. The inlet duct is in fluid communication with the ductwork assembly 500, such as via the duct 506, whether directly or via indirectly, such as via an interconnect duct. The cylindrical body comprises a sidewall through which the inlet duct is in fluid communication with the cylindrical body, above the conical section 706. The separator 704 further comprises a rectilinear tubular outlet duct in fluid communication with the cyclone body at a second end of the cylindrical body opposing the first end. The conical section 706 comprises an open end opposite from the second end along a vertical axis on which the first end and the second end are positioned. The rectilinear tubular outlet duct is in fluid communication with the ductwork 710.
The chute 708 comprises a U-shape cross-section, while extending longitudinally along a diagonal plane. However, note that the chute 708 can also comprise an O-shape cross-section, such as a tubular duct, which can be polygonal. The chute 708 is configured to receive material from the open end of the conical section 706. The chute 708 is positionally fixed. However, in other embodiments, the chute 708 is positionally adjustable, whether along a horizontal plane or a vertical plane. In yet other embodiments, the chute 708 is longitudinally extendible, whether manually or automatically, such as via telescoping.
The material processing assembly 700 further comprises a suction source 712 resting on the ground surface and a ductwork 710 in fluid communication with the suction source 712 and the cyclone separator 704. The suction source 712 provides negative air or gas pressure to suction the material from the ductwork assembly 500, as received from the separation assembly 400. For example, the suction source 712 is a motorized suction pump configured to create a pressure difference to provide continuous suctioning action. In other embodiments, the frame 702 hosts the suction source 712, such as via fastening, mating, interlocking, adhering, clamping, nesting, adhering, magnetizing, or other methods.
As the dirty air is input via the inlet duct into the cylindrical body, such as in a laterally originating path from the duct 506, the dirty air begins to flow within the cylindrical body in a downward helical pattern from a top portion of the cylindrical body, i.e. from the outlet duct, toward the open end of the conical section 706 before exiting the cylindrical body in a straight upward stream path through a center of the helical pattern via the rectilinear outlet duct along the vertical axis along which the first end and the second end are positioned. Such upstream airflow is directed to the ductwork 710 through which the suction 712 provides suctioning action, whether on a continuous or a periodic basis. However, when the dirty air enters the conical section 706, the dirt in the air has excessive inertia to follow a tight curve flow of the hot air upward toward the rectilinear outlet duct, such as due to size or density. Resultantly, the dirt strikes an inner surface of the conical section 706. Since a rotational path is reduced in the conical section 706, due to a tapering volume of the conical section 706, such striking action causes the dirt to separate into a set of small particles, which are output through the open end of the conical section 706 based at least in part on natural gravity. Accordingly, the dirt exits the conical section 706 and falls onto the chute 708. The air, which is effectively substantially free from the dirt, exits the separator 704, via the rectilinear outlet duct toward the ductwork 710 as suctioned via the suction source 712.

The control area 200 comprises a support structure 202 and a control room 204 positioned atop of the support structure 202. The room 204 comprises a window 206 configured to provide a view onto at least one of the air source assembly 300 and the separation assembly 400. A bridge 208 spans between the support structure 202 and the frame 404.
The structure 202 can be of any type, such as a tower, whether with a lattice or without a lattice, which can comprise a ladder, an elevator, or an escalator, which can be motorized. In other embodiments, the room 204 is not positioned atop of the support structure, such as where the support structure 202 extends past the room 204. The room 204 can be of any type, shape, or volume, whether permanent or temporary. The window 206 can be of any type or shape. The window 206 can be permanently open or opened, whether manually or automatically, whether in a pivotal or a sliding manner. The window 206 can be closed, whether manually or automatically, whether in a pivotal or a sliding manner. The bridge 208 can be of any type, whether fixed or movable, whether single-deck or multiple-deck, whether a beam type, a truss type, a cantilever type, an arch type, a tied arch type, a suspension type, or a cable-stayed type. For example, a user can leave the control room 204 and walk across the bride 208 onto the frame 404 for an operational inspection.
The room 202 contains a computer/control panel for control of the system 100 or at least one of the air source assembly 300, the separation assembly 400, the ductwork assembly 500, the tower assembly 600, the material processing assembly 700, the input material section 800, the output material section 900, the material processing section 1000, and the mill 1100, whether in a wired or a wireless manner, whether directly or indirectly, whether in whole or in part. For example, such control can occur via a programmable logic controller (PLC) coupled to at least one of the air source assembly 300, the separation assembly 400, the ductwork assembly 500, the tower assembly 600, the material processing assembly 700, the input material section 800, the output material section 900, the material processing section 1000, and the mill 1100. The computer/control panel comprises a user interface configured to receive a user input, such as via an input device, such as a keyboard, a mouse, a joystick, a gamepad, or a touchscreen. The computer/control panel comprises an output device, such as a display, a speaker, a vibrator, or a printer. The computer/control panel can be powered as described herein. The computer/control panel can be coupled to a network, whether in a wired manner or a wireless manner, whether directly or indirectly.
The air source assembly 300 comprises the frame 302 hosting the separator 304, which comprises an inlet duct 307, a cyclone cylindrical body 305 in fluid communication with the inlet duct 307, and the conical section 308 in fluid communication with the cyclone body 305 at a first end of the cyclone body 305. The cylindrical body 305 comprises a sidewall through which the inlet duct 307 is in fluid communication therewith, above the conical section 308. The separator 304 further comprises a rectilinear tubular outlet duct 303 in fluid communication with the cyclone body 305 at a second end of the cyclone body 305 opposing the first end. Note that a top end of the rectilinear outlet duct 303 is closed. The separator 304 also comprises an arcuate duct 310 in fluid communication with the rectilinear tubular outlet duct 303 via a sidewall thereof. The arcuate duct 310 is in fluid communication with the duct 306. The duct 306 is in fluid communication with the air supply section 408. The conical section 308 comprises an open end 309 opposite from the second end along a vertical axis on which the first end and the second end are positioned.
As the dirty hot air is input via the inlet duct 307 into the cyclone body 305, the dirty hot air begins to flow within the cyclone body 305 in a downward helical pattern from a top portion of the cyclone body 305, i.e. from the outlet duct 303, toward the open end 309 of the conical section 308 before exiting the cyclone body 305 in a straight upward stream path through a center of the helical pattern via the rectilinear outlet duct 303 along the vertical axis along which the first end and the second end are positioned, where the duct 303 conducts such air to the duct 310. However, when the dirty hot air enters the conical section 308, the dirt in the hot forced air has excessive inertia to follow a tight curve flow of the hot air upward toward the rectilinear outlet duct 303, such as due to size or density. Resultantly, the dirt strikes the inner surface of the conical section 308. Since the rotational path is reduced in the conical section 308, due to the tapering volume of the conical section 308, such striking action causes the dirt to separate into a set of small particles, which are output through the open end 309 of the conical section 308 based at least in part on natural gravity. Accordingly, the dirt exits the conical section 308 and falls onto the ground surface, such as to form a pile of dirt on the ground surface. The air, which is effectively substantially free from the dirt, exits the separator 304 via the rectilinear outlet duct 303, which conducts such air to the duct 310. The duct 310 conducts the air to the duct 306, which conducts such air to the air supply section 408 for use by the dryer section 406 and the separation section 410.
The air supply section 408 provides forced air to the separation section 410 such that the separation section 410 separates the material received from the drier section 406 into the plurality of constituents, such as a first constituent and a second constituent. The air supply section 408 comprises a ductwork defined via a first duct segment 408A and a second duct segment 408B branching off from a common duct of the air supply section 408. The segment 408A and the segment 408B are in conductively parallel relationship with each other. The segment 408A conducts the air from the duct 306 to the separation section 410, such as to an air knife positioned within the separation section 410. The segment 408B conducts the air from the duct 306 to the dryer section 406, such as into a dryer drum positioned within the dryer section 406. Note that the segment 408A tapers away from the common duct of the air supply section 408 from which the segment 408A and the segment 408B branch off. Such tapering enables relatively uniform air or gas flow pressure maintenance as the segment 408A provides air or gas to a set of serially positioned separation stations within the separation section 410. However, in other embodiments, the segment 408A remains uniformly shaped or widens in shape as the segment 408A extends away from the common duct of the air supply section 408, whether the segment 408A provides air or gas to a set of separation stations serially or in parallel.

The input conveyor section 402 comprises a conveyor 402C and a leg 402L, which are positioned in a T-shaped relationship with each other. Note that other types of positioning relationships are possible, such as a U-shape or an L-shape. The conveyor 402C is driven via a motor coupled to the leg 402L, such as underneath the conveyor 402C. Such motor can be of any type, such as an electric servomotor operating a belt of the conveyor 402C. The conveyor 402C comprises a shield 402S extending therefrom. The shield 402S can be solid or perforated, whether transparent, opaque, or translucent, whether in whole or in part. The conveyor 402C receives the material from the conveyor 802, which is perpendicularly conveying to the conveyor 402. In other embodiments, such conveyance relationship is based on a different orientation, such as diagonal. The shield 402S effectively prevents the material, which is conveyed on the conveyor 802, from falling off during a conveyance from the conveyor 802 to the conveyor 402C.
The input conveyor section 402 is positioned underneath the return conveyor section 414, which comprises a pair of columns 414S providing support thereto. Such placement can be offset or directly underneath, whether in part or in whole. The input conveyor section 402 is also positioned upstream from the dryer section 406. The conveyor 402C or the leg 402L are operably coupled to the columns 414S for movement along a horizontal plane, with respect to the columns 414S, between a plurality of positions, which can correspond to a plurality of operational modes. For example, such coupling can be via the leg 402L, where the conveyor 402C travels between such positions based on the leg 402L being moved along the horizontal plane, such as via a set of rails coupled to the columns 414S. The movement is motorized, such as via a motor, such as an electric motor. Such movement can be based at least in part on a manual input, such as via the computer/control panel in the room 204. Whether additionally or alternatively, such movement can also be based at least in part on an automatic input, such as via a computer program running on the computer/control panel in the room 204 or via a processing circuit, such as a PLC, operably coupled to the system 100. Note that such movement can include tilting or lateraling as well.
In a first position, as shown in FIG. 15A, which is a detrashing bypass mode, which can be a rightmost position of the conveyor 402C, the conveyor 402C is retracted toward the dryer section 406 such that the conveyor 802 is unable to convey the material to the conveyor 402C. Accordingly, the conveyor 802 conveys the material to the conveyor 902, which is shredded via at least one of the rotary shredders 904.
In a second position, as shown in FIG. 15B, which is a detrashing operational mode, which can be an intermediate position of the conveyor 402C, the conveyor 402C is moved to receive the material from the conveyor 802, such as at or below the conveyor 802. For example, such material can comprise sugarcane billets and trash. Also, for example, the material can be conveyed perpendicularly from the conveyor 802 onto the conveyor 402C. Resultantly, the conveyor 402C conveys the material toward the dryer section 406.
In a third position, as shown in FIG. 15C, which is a foreign matter reject position, which can be a leftmost position of the conveyor 402C, the conveyor 402C is retracted such that a gap is created between the conveyor 402C and the dryer section 406. For example, the gap can be about four feet long along the horizontal plane. Therefore, the conveyor 402C is able to receive the material from the conveyor 802, yet unable to convey the material onto the dryer section 406. Resultantly, the conveyor 402C conveys the material such that the material falls into the gap and onto the ground surface before entering the dryer section 406. Otherwise, upon entry into the dryer section 406, such material can cause damage at least to the dryer section 406, such as scratching. Once the foreign matter is rejected or the sensor does not sense such matter, then the conveyor 402C automatically returns into the second position.
In other embodiments, the input conveyor section 402 can comprise a chute mounted below the conveyor 402C and configured to receive the material with the foreign matter. Such chute can comprise a U-shape cross-section, while extending longitudinally along a diagonal plane. However, note that such chute can also comprise an 0-shape cross-section, such as a tubular duct, which can be polygonal. Such chute is positionally fixed. However, in other embodiments, such chute is positionally adjustable, whether along a horizontal plane or a vertical plane. In yet other embodiments, such chute is longitudinally extendible, whether manually or automatically, such as via telescoping.
The foreign matter can comprise a metal, a material comprising a metallic property, a metal compound, a metallic compound, or a metal alloy. For example, the foreign matter in the sugarcane trash can comprise iron, steel, aluminum, gold, silver, carbide, or others. In some embodiments, the foreign matter can also be non-metallic. The foreign matter is detected via a suitable sensor mounted over the conveyor 802 and in operable communication with the computer/control panel. Accordingly, upon a detection of the foreign matter via the sensor, the computer/control panel instructs the conveyor 402C to move away from the dryer section 406 such that the conveyor 402C is able to receive the material from the conveyor 802, yet unable to convey the material onto the dryer section 406, with the material with the foreign matter falling into the gap.
Whether additionally or alternatively, at least one of the conveyor 802 and the conveyor 402C comprises a magnet disposed thereabove. The magnet can attract at least one of a metal, a material comprising a metallic property, a metal compound, a metallic compound, or a metal alloy if mixed with the material being conveyed. Via such attraction, the magnet can pull out the foreign matter from the material during the conveyance via at least one of the conveyor 802 and the conveyor 402C, which would prevent such matter from entering at least the dryer section 406.

The fingers 410H1 are positionally fixed, but can be pivoting, such as about a diagonal axis, vertical axis or a horizontal axis. The compartments 410H are identical to each other in volume or shape, but can be different. For example, when the portion 410A1 is substantially closed except for the 12 o'clock and 6 o'clock positions, the material in the compartments 410H remains in the compartments 410H until or before the 12 o'clock position, such as about 10 o'clock, when the material gravitationally falls out or starts falling out from the compartments 410H.

The door 410K3 comprises a handle, but can lack one as well. When opened, the door 410K3 provides a hands on or tool access to the inner chamber of the duct 410K or the at least partially open bottom surface or the bottom opening, such as for clean up or maintenance. When closed, the door 410K3 can provide a seal to the duct 410K for fluid flow efficiency, which can be hermetic. The duct 410K is in fluid communication with the segment 412B via the opening 410K3.

In the second position, the lifter 410D elevates the material to an upper quadrant of the lifter 410D, as the product is stored in the compartments 410H. In the upper quadrant, the lifter 410D drops the material, such as the sugarcane billets and remaining trash, onto the conveyor 410I. During the drop, the air or gas, which can be heated as described herein, under pressure, from the air knife 410C separates the material, such as the trash from the sugarcane billets, and blows some of the constituents of the material, such as the trash, toward the opening 410K2, which is in fluid communication with the segment 412B. Resultantly, some of the heavier constituents of the material, such as the sugarcane billets, drop onto conveyor 410I that drops that material into a subsequent lifter 410D. Such process is repeated by the subsequent lifter 410D, with each instance separating the material to a higher degree than before. Note that such drop can be a slide or a release, whether active or passive, whether with a force application or gravitationally induced, whether direct or indirect, whether in whole or in part.
Note that although the segments 412A, 412B suction from different directions, such configuration can be different in other embodiments. For example, the segments 412A, 412B can both extend in one direction, such as toward the conveyor 800 or away from the conveyor 800. Note that although the lifters 410D are extending along a diagonal plane, in other embodiments the lifters 410D can be stationed along a horizontal plane. Similar configurations can be achieved with the air knives 410C in any manner as described herein. Note that since the air or gas pressure or temperature can decrease if the air knives 410C are fed from one conduit, in other embodiments, the air knives 410C can be fed from more than one conduit and/or comprise air pressure boosters between the air knives 410C to maintain a relative pressure among the air knives 410C. However, in some embodiments, the pressure can be increasing as the material travels upward to improve the separation process and/or decrease as the material travels upward because undesired material frequency decreases with each level of travel between the lifters 410D.
FIG. 32 shows a perspective view of an example embodiment of a return conveyor according to the present disclosure. FIG. 33 shows a longitudinal cross-sectional view of an example embodiment of a return conveyor according to the present disclosure. Some elements of these figures are described above. Thus, same reference characters identify identical and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication.
The return conveyor section 414 comprises a chute into which the last duct 410K conducts the material, as serially separated. For example, such material comprises sugarcane billets as substantially separated from the sugarcane trash. The chute comprises a U-shape cross-section, while extending longitudinally along a diagonal plane. However, in other embodiments, the chute can also comprise an O-shape cross-section, such as a tubular duct, which can be polygonal. The chute is configured to receive material from the at least partially open bottom surface or the bottom opening of the duct 410K. The chute is positionally fixed. However, in other embodiments, the chute is positionally adjustable, whether along a horizontal plane or a vertical plane. In yet other embodiments, the chute is longitudinally extendible, whether manually or automatically, such as via telescoping.
The section 414 comprises a bin 414A and a motorized conveyor 414F hosted in the bin 414A. The bin 414A can be of any type, shape, or volume. The conveyor 414F can be of any type. The bin 414A defines an interior open space 4148 with access to the conveyor 414F. The space 414B can be of any volume or shape. The section 414 comprises an upper portion 414D and a door 414E. The section 414 comprises a movement mechanism 414C, which slidably lifts the door 414E with respect to the portion 414D along a diagonal plane to provide access to the space 414B Such lifting creates an exit opening for the material, which can be of any shape or size. Alternatively, the door 414E pivots, such as hingedly, to allow for the material to exit. Accordingly, the conveyor 414 receives the material from the chute and conveys the material horizontally toward the door 414E, which is slid open via the mechanism 414C. Some of the material on the conveyor 414F exits via the exit opening. However, when the material piles up on the conveyor 414F, such as being higher than the door 414E can accommodate, the portion 414D applies force to the piled up material to exit the bin 414A through the exit opening. Note that the material output section 900 can receive the material from the exit opening.
FIG. 34 shows a perspective view of an example embodiment of a material processing assembly according to the present disclosure. Some elements of this figure are described above. Thus, same reference characters identify identical and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication.
The material processing assembly 700 comprises the suction source 712 resting on the ground surface and the ductwork 710 in fluid communication with the suction source 712 and the cyclone separator 704. The suction source 712 provides negative air or gas pressure to suction the material from the ductwork assembly 500, as received from the separation assembly 400. For example, the suction source 712 is a motorized suction pump configured to create a pressure difference to provide continuous suctioning action. In other embodiments, the frame 702 hosts the suction source 712, such as via fastening, mating, interlocking, adhering, clamping, nesting, adhering, magnetizing, or other methods.
The frame 702 hosts the separator 704, which comprises a duct 707, a cyclone cylindrical body 705 in fluid communication with the duct 707, and the conical section 706 in fluid communication with the cyclone body 705 at a first end of the cyclone body 705. The separator 704 operates opposite from the air supply section 300, such as the separator 304. In contrast to the separator 304 supplying air, the separator 704 suctions air via cyclonic separation principles.
As the dirty air is input via the inlet duct into the cylindrical body 705, such as in a laterally originating path from the duct 506, the dirty air begins to flow within the cylindrical body 705 in a downward helical pattern from a top portion of the cylindrical body 705, i.e. from the duct 707, toward the open end of the conical section 706 before exiting the cylindrical body 705 in a straight upward stream path through a center of the helical pattern via the duct 707 along the vertical axis along which the first end and the second end are positioned. Such upstream airflow is directed to the ductwork 710 through which the suction 712 provides suctioning action, whether on a continuous or a periodic basis. However, when the dirty air enters the conical section 706, the dirt in the air has excessive inertia to follow a tight curve flow of the hot air upward toward the duct 707, such as due to size or density. Resultantly, the dirt strikes an inner surface of the conical section 706. Since a rotational path is reduced in the conical section 706, due to a tapering volume of the conical section 706, such striking action causes the dirt to separate into a set of small particles, which are output through the open end of the conical section 706 based at least in part on natural gravity. Accordingly, the dirt exits the conical section 706 and falls onto the chute 708. The air, which is effectively substantially free from the dirt, exits the separator 704, via the rectilinear outlet duct toward the ductwork 710 as suctioned via the suction source 712. The suction source exits such air via a duct 709.
FIG. 35 shows a schematic flow diagram of an example embodiment of a method for detrashing according to the present disclosure. Some elements of this figure are described above. Thus, same reference characters identify identical and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication.
As described herein, the air or gas is provided by the air supply section 300 to the separation sections 410 via the segment 408A and to the dryer section 406 via the segment 408B. The dryer section 406 receives the material from the input conveyor section 402. Upon exit from the dryer section 406, based on the air or gas, the material is separated, with some of the constituents of the material exiting via the segment 412A through the ductwork assembly 500 to the material processing assembly 700, and with some of the constituents of the material being conducted to the separation sections 410 for further separation. Based on such separation via the air or gas, the material is separated, with some of the constituents of the material being conducted to the separation sections 410 for further separation and some of the constituents of the material exiting via the segment 412B through the ductwork assembly 500 to the material processing assembly 700. Such process iterates based on a number of the separation stations in the separation section. Accordingly, the return conveyor section 414 receives the material, which has been separated as desired.
In some embodiments, the system 100 can handle about 1250 metric tons of sugarcane biomass per hour and extract a minimum of about 85% of the trash and ash present in the biomass. The system 100 has enough biomass extraction capacity to include all field trash (material currently left in a field). The field trash can be transported to the sugar mill and all sugarcane billets currently left behind in the field can be processed for sugar extraction increasing sugar yields up to about 8% per acre. The system 100 is designed to extract most, if not all, metallic objects in the biomass before entry at least into the drum 406L. The system 100 includes four vacuum stations and three high-pressure blowing systems utilizing hot air to separate the trash and ash from the sugarcane billets. However, those numbers can be higher or lower. The system 100 elevates the material via lifter drums to drop the material three times for trash extraction. The system 100 transfers the clean sugarcane billets after the last drop into a chute and the cleaned sugarcane billets slide to an accumulation conveyor. The system 100 transfers the clean sugarcane billets back to the mill from the accumulation conveyor at a controlled rate desired for mill operations. The system 100 can extract dirt in extremely wet conditions, such as about 2 inches of rainwater per hour. The system 100 can utilize waste heat to separate leaves and dirt from the sugarcane billets. The system 100 can separate trash and dirt at the mill before the material enters the sugar making process reducing wear and tear on at least some mechanical mill systems. The system 100 can be designed for flexible speed to follow the sugar mills variable crushing speed. The system 100 can increase a crushing capacity of the mill by up to about 20%. The system 100 can be designed to return the biomass at the exact point where the system 100 receives the biomass. In some embodiments, the system 100 is housed indoors, such as in a warehouse and/or a tent, with some outputs exiting to outdoors. Note that such drop can be a slide or a release, whether active or passive, whether with a force application or gravitationally induced, whether direct or indirect, whether in whole or in part.
