     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention is directed to shale shakers with cartridge screen assemblies. 
     2. Description of Related Art 
     Vibratory separators are used in a wide variety of industries to separate materials such as liquids from solids or solids from solids. Typically such separators have a basket or other screen holding or mounting apparatus mounted in or over a receiving receptacle or tank and vibrating apparatus for vibrating the basket. One or more screens is mounted in the basket. Material to be treated is introduced to the screen(s) either by flowing it directly onto the screen(s) or by flowing it into a container, tank, or “possum belly” from which it then flows to the screen(s). Also in some multi-screen apparatuses material flows generally horizontally or uphill from one screen to another and, in certain systems, from an upper screen onto a lower screen. 
       FIG. 1  illustrates an apparatus according to the prior art, in which the debris laden mud  1  flows downwardly through a vibrating flat screen  2  to filter out the debris. The screen  2  is vibrated by vibrating the whole body of the apparatus using motors  3  with eccentric weights, for example. The cleaned mud exits the apparatus and then generally is ready for re-use. Debris that does not pass through the screen is caught on the screen and is carried by the direction and amplitude of the screen vibration upwardly towards an exit  4 . Corrugated shaped screens have been used in the industry. In certain prior art screens the mud passes either vertically down through the screen, as is the case with the flat screens, or has a downward component to the flow, as is the case with certain three-dimensional screens. Arrangements have been proposed where the angle of the screen is increased and may be vertical in parts. 
     Examples of the general configuration of filter are disclosed in U.S. Pat. No. 4,459,207, WO-A-02 43 832 and WO-A-03 028 907.

In showing and describing the preferred embodiments, like or identical reference numerals are used to identify common or similar elements. The figures are not necessarily to scale and certain features and certain views of the figures may be shown exaggerated in scale or in schematic in the interest of clarity and conciseness. 
     As used herein and throughout all the various portions (and headings) of this patent, the terms “invention”, “present invention” and variations thereof mean one or more embodiment, and are not intended to mean the claimed invention of any particular appended claim(s) or all of the appended claims. Accordingly, the subject or topic of each such reference is not automatically or necessarily part of, or required by, any particular claim(s) merely because of such reference. 
     DETAILED DESCRIPTION OF THE INVENTION 
       FIGS. 1-4  present subject matter which the present invention improves. 
       FIG. 2  shows new directions of flow for drilling fluid or mud with entrained debris. The mud passes through the screen either vertically  5 , horizontally  6 , or with an upward component  7 . The debris falls under gravity to the lower surface  8  where it is conveyed out of the apparatus. The lower surface  8  may be a mesh screen, a roughened plate or a rotating belt or chain(s). The design of the apparatus is such that it is not possible for debris laden mud to bypass the screens. Unlike in certain prior art configurations, the mud is introduced into a compartment under the screens, not from above the screens. The pressure required to force the mud through the screen is provided by the height of a pool of mud adjacent to the screening compartment, although alternatively this could be provided for by other means such as a centrifugal pump. 
     Referring now to  FIGS. 3 and 4 , debris-laden fluid or mud is introduced into a pool  9 , and the fluid is forced through a vibrating screen  10  into a channel  11  that allows the substantially debris free mud to flow via pipe work or channels  12  to tanks for subsequent re-use. The cleaned mud may either exit the shakers from the sides or bottom of the shaker. The debris falls under gravity to a lower surface  13 , which conveys the debris out from under the screen by vibration or via a moving belt. An inclined surface  14  conveys the debris out of the pool. This mode of conveyance may alternatively be a moving belt; however it is preferably similar to prior art inclined surfaces and consists of a vibrating screen which will assist the removal of mud from the debris. The debris  15  exiting the device may be sent to a screw press, centrifugal device or prior art shaker to further recover mud closely associated with the debris. 
       FIG. 5  shows an alternative arrangement, in which a main enclosure  20  contains a filter body  21  whose lowermost wall consists of a screen  22  which can be vibrated with the body  21  or independently thereof. In either case, the energy required to vibrate the screen is substantially smaller than would be required for vibration of the whole apparatus, as in the prior art apparatus. Debris-laden mud enters at  23  and the head of mud above the level of the screen  22  is sufficient to drive the mud through the screen into the body  21 , from where it can flow out at  24  for re-use. Debris retained by the screen  22  is dislodged by the vibration and falls on to a horizontal conveyor belt  25 , which carries it on to an inclined conveyor belt  26 . This belt  26  carries the debris out of the mud and discharges it into a chute  27 , from which it falls on to a secondary vibrating screen  28  arranged to remove residual mud for re-use before discharging the debris for disposal. 
     The embodiment of  FIG. 6  has a filtration section  30  of uniform cross-section and a tapering section  31  beneath it. The filtration section  30  contains a vibrating screen  32  mounted so as to separate the filtration section into two sections: a lower inlet section  33  and an upper outlet section  34 . The inlet section  33  is supplied with debris-laden mud via a supply pipe  35 . The mud is pumped or otherwise supplied at a pressure sufficient to urge it upwardly through the vibrating screen  32  and into the outlet section  34 , from where it flows for re-use through an outlet pipe  36 . 
     Debris retained by the screen  32  falls into the tapering section  31 , where it settles. An auger  37  is mounted in the lowermost part of the tapering section  31  and can be driven by an external motor (not shown) to urge the settled material out of the apparatus for disposal or further filtration or treatment as required to extract any residual liquid mud. In order to ensure that the minimum of liquid is removed in this manner, the tapering section  31  can be provided with a sensor to detect density or liquid content of the settled material above the auger  37  and to prevent operation of the external motor when the liquid content of the material adjacent to the auger is above a predetermined proportion, thereby preventing the loss of excess liquid mud. 
     It will be understood that, while the debris is represented in the drawings as discrete lumps or rock pieces, it will typically be a mixture of larger and smaller particles and pieces. 
       FIGS. 7A-7C  illustrate a system  100  according to the present invention which has a housing  102  for containing material M to be treated. A screen apparatus  110  is removably secured to a box  104  which is mounted to the housing  102 . Any known structure and/or apparatus may be used to removably secure the screen apparatus  110  to the box  104  and, as shown, in one aspect, a known inflatable seal apparatus  106  is used for this purpose. 
     Vibratory apparatus  108  connected to the box  104  vibrates the box  104  and thus the screen apparatus  110 . Any suitable known vibratory apparatus may be used for the vibratory apparatus  108 . Any suitable known screen or screens, screen assembly or screen assemblies may be used for the screen apparatus  110 . The box  104  is mounted on anti-vibration mounts  122 . 
     An arrow  112  indicates the introduction of the material M (including, but not limited to, drilling material including drilling fluid or mud, and drilled solids and debris) into the housing  102 . Arrows  114  indicate the flow of the material M up to and through the screen apparatus  110 . An arrow  116  indicates the discharge of recovered cleaned fluid  124  through a discharge duct  118  from the box  104  (shown schematically in  FIG. 7C ). In one aspect the duct  118  is flexible or has a flexible portion so that the duct  118  and the box  104  can be lowered in the housing  102 , e.g. for access, maintenance, or cleaning. A deflector  117  directs incoming fluid flow. Heavier solids, directed by the deflector  117 , will flow downwardly to the conveyor system  130  and will not impact the screen apparatus  110 . 
     Solids S that do not pass through the screen apparatus  110  fall within the housing  102  and enter a conveyor system  130 . An auger apparatus  132  rotated by a motor  134  augers the solids S up to a discharge opening  136 . An arrow  138  indicates the flow of the material with discharged solids from the system  100  to storage, to disposal, or to additional processing. 
     According to the present invention, one, two, three, four, or more auger apparatuses may be used with a system according to the present invention; e.g. the system  100  as shown in  FIG. 7B  has three auger apparatuses  132 . Optionally, the system  100  is enclosed with an enclosure  140 . In one aspect air, fumes, gases, and/or material entrained in air above the box  104  are evacuated through an access opening  142 . Optionally this is accomplished by an HVAC system  144  and/or a filtration system  146  with appropriate pumping apparatus and/or vacuum apparatus. Optionally the enclosure  140  itself or the enclosure  140  with sound insulation material  148  reduces noise from the system  100 . 
       FIG. 8  illustrates one embodiment of the system  100  (and like numerals indicate like parts) which includes a screen apparatus  150  which receives the discharged material  138 . It is within the scope of the present invention for the screen apparatus  150  to be inclined downwardly and for material to move off of it under the influence of gravity; or, as shown, in  FIG. 8  the screen apparatus  150  includes vibratory apparatus  155  (like, e.g. the vibratory apparatus  108 ) which vibrates a screen or screens  152  (e.g. like the screen apparatus  110 ). Separated solids  154  flow off an exit end  156  of the screen(s)  152  and reclaimed fluid  158  flows to a receptacle or container  159 . 
       FIGS. 9A-9C  illustrate an embodiment of a system  100  according to the present invention (like numerals indicate like parts) which includes at least one additional conveyor system  160  (like the conveyor system  130 ) which is oriented in a generally vertical orientation. A conveyor system  130   a , like the system  130 , may be oriented as shown in  FIG. 7A  or, as shown in  FIG. 9A , may be oriented generally horizontally. The conveyor system  130   a  moves material with separated solids to the conveyor system  160  which, in turn, moves the material up to an exit duct  166 . An optional paddle  168 , secured to an auger apparatus  162  of the system  160  so that it is adjacent the duct  166 , facilitates the movement of material into the exit duct  166 . In one aspect the paddle  168  is a straight blade section on the auger apparatus  162  (as opposed to screw flights on the rest of the auger apparatus  162 . Optionally, in one aspect a reversed flight  169  is used at the top of the auger apparatus (see, e.g.  FIG. 10A ) which moves material downwardly to the duct  166 . Such a flight  169  can be used with the paddle  168 . 
     Material with separated solids may, according to the present invention, flow to storage or to further processing or, as shown in  FIG. 9A , may be introduced to a vibratory separator apparatus  170  with screening apparatus  172  (like the screening apparatus  110 ) vibrated by vibratory apparatus  178  (like the vibratory apparatus  108 ). It is within the scope of the present invention for the material with solids separated by the vibratory separator apparatus to flow to disposal, to storage, or to further processing. Reclaimed fluid from the vibratory separator apparatus  170  can be directed to storage or to a container; or, as shown in  FIG. 9A  by an arrow  174 , it can flow back into the housing  102 . 
     Optionally, a valve  180  selectively controls the flow of fluid into the housing  102 . Optionally, in addition to (or instead of) the screen apparatus  110 , one or more walls of the box  104  may have a screen mounted therein or thereon, or a screen or screens can be secured to the box  104 . For example, as shown in  FIG. 9C  two inclined screens  181 ,  182  (like the screen apparatus  110 ) are secured to the box  104  and material M is flowable through the screens  181 ,  182  and through the screen apparatus  110 . Additionally, and optionally, a further screen  183 , oriented generally vertically, may be located to a vertical face  184  of the box  104 . 
     In certain aspects, the use of an additional conveyor, such as the conveyor system  160 , makes it possible for the material depth within the housing  102  to be increased as compared to a system with a lower conveyor system or systems. This can permit a screen apparatus to be set relatively deeper in a box which can result in side screens being taller so that more screening area is provided in a specified footprint area. In certain aspects according to the present invention, to empty a system as in  FIG. 9A  a height adjustment is made for both the box  104  and the duct  118 . 
       FIG. 10A  illustrates a system  100   b  like the system  100   a  of  FIG. 9A  (like numerals indicate like parts) which includes a solids conveying system  190 . Solids separated by the vibratory separator apparatus  170  are introduced to the solids conveying system  190 . In one particular aspect the solids introduced to the system  190  are drilled cuttings separated from a material that includes drilling fluid and drilled solids (“drilled cuttings”) and the system  190  is a drilled cuttings conveyance system. It is within the scope of the present invention to employ any suitable known cuttings conveyance system for the system  190 . 
     As shown in  FIG. 11  a system  196  according to the present invention may have a plurality of vibratory separators  191 ,  192 ,  193  (as any according to the present invention; in one aspect, each vibratory separator is a shale shaker processing drilling material). Material to be processed flows in a feed conduit or “gutter”  195  and each separator or shaker  191 - 193  has a flow valve  180   a ,  180   b ,  180   c , respectively which selectively controls flow to each separator or shaker  191 - 193 . Thus one, two or three separators or shakers  191 - 193  can be operational as desired.

       FIG. 12  shows a system M according to the present invention which has a container C into which material R is introduced, e.g. the material including liquid L and solids S. The material R flows to a screen apparatus A which is mounted in a basket or box X. Part P of the material, e.g. liquid or liquid plus some solids, flows up through the screen apparatus A. The part P is removed from the system by removal apparatus V (e.g. vacuum or pump apparatus). Part of the material, e.g. solids S and agglomerations or masses of solids, either settles down in the container C without contacting the screen apparatus A or, upon being prevented from further upward flow by the screen apparatus A and/or by material already adjacent the screen apparatus A, falls downwardly in the container C. 
     Electromagnetic vibrator apparatus O vibrates the basket X and, thus, the screen apparatus A. It is within the scope of the present invention to use one, two, three, four or more electromagnetic vibrator apparatuses (and to do so for any vibrator or vibration apparatus of any embodiment disclosed herein). It is within the scope of the present invention for the screen apparatus A (and the apparatus  110  described below) to be any suitable known screen or screen assembly used for vibratory separators or shale shakers. In one particular aspect the material R is drilling material with drilling fluid and drilled solids. Instead of, or in addition to, one or more electromagnetic vibrator apparatuses, according to the present invention, (as is true for any embodiment according to the present invention) one, two, three, four or more piezoelectric vibration apparatuses are used. Also, according to the present invention any vibrator or vibration apparatus of any embodiment according to the present invention may be connected directly to the screen apparatus instead of to the basket X. Appropriate mounts and/or isolators and/or shock absorbers O may be used to mount the vibrator or vibration apparatuses to a basket or directly to a screen apparatus. 
     It is within the scope of the present invention for any screen or screen assembly in any box or container of any system according to the present invention to be bowed, inwardly or outwardly, i.e., not flat across its extent (outwardly as in  FIGS. 13 ,  14 ).

Holding apparatus  104   h  holds a screen  183   e  bowed over a central member  104   i.    
       FIG. 15  shows a system  200  according to the present invention which has a box  204  according to the present invention (e.g. any box according to the present invention, e.g. like the boxes of  FIGS. 7A ,  8 ,  9 A,  9 C,  10 A,  13 ,  14 ) removably secured within a basket  206 . Separated material (with some liquid) flows down to an auger system  208  which moves the material to an optional pump apparatus  210  (shown schematically) in a housing  212 . 
     Material flowing up in the housing  212  (in one aspect moved by the pump apparatus  210  driven by a motor  250 ) encounters a porous body  214  which permits liquid (e.g. drilling fluid from the material) to flow in a line  216  back into the basket  206 . Solids (with some liquid) flow on a member  218  either out of the system for storage and/or further processing or, as shown, flow to a secondary shaker system  220 . 
     In the secondary shaker system  220  a motor  222  vibrates a screen or screens  224  mounted on isolation mounts  226 . Liquid flowing down through the screens  224  flows down to a member  226  and then back into the basket  206  through a line  228 ; or, optionally, the wall WL is removed. Solids (with some liquid) flow off the ends of the screen(s)  224  for collection, storage, and/or further processing. 
     The basket  206  has primary inlet  232  and, optionally, an alternative or additional inlet  234  for material (e.g. drilling fluid with drilled solids entrained therein) to be treated by the system  200 . Overflow is handled with a liquid overflow line  236 . Gases are vented through a vent connection  238 . A motor  230  vibrates the box  204  (optionally, the motor  230  vibrates the basket  206  or the basket  206  and the box  204 ). 
     Screens  240  (at the bottom) and screens  242  (on the sides) are removably secured to the box  204  (two screens  242  on each box side). 
     A level sensor  270  senses the level of material in the basket  206  and sends a signal indicative of the level to a control system  280 . The control system  280  processes these signals and controls basket speed and vibration which affect the feed of material into the basket  206 . The control system  280  is used to maintain a desired level of material in the basket and for controlling a valve  232   a  which permits flow to the inlet  232 . 
     The apparatus  210  and/or the secondary shaker  200  can be used with any system according to the present invention. 
       FIG. 16  shows a system  300  like the system  200  (like numerals indicate like parts) but without the apparatus  210 . The auger  208  feeds material to a pump apparatus  310  which pumps the material in a line  312  up to the filter  214 . 
     In one aspect the pump apparatus  310  is a MONO (trademark) pump from Mono Pumps Ltd and in one particular aspect a MONOBLOC (trademark) B Range pump is used. 
     Material pumped upwardly past the filter  214  is directed by members  314  and  316  to the secondary shaker  220 . In certain aspects the auger  208  and the pump apparatus  310  each has its own dedicated motor drive system. As shown in  FIG. 16 , a single drive system  209  turns the auger  208  and drives the pump apparatus  310  via shaft  316 . 
     In certain aspects the auger  208  is deleted and the pump apparatus  310  alone evacuates material from beneath the box  204  and transfers it into the line  312 . It is within the scope of the present invention in any system disclosed herein to delete auger apparatus(es) (any one, two, or all) and replace it or them with a pump apparatus like the pump apparatus  310 .
