Description: ELECTRO-SMOKELESS EXTRACTION/RECOVERY SYSTEM Background of the Invention This application is based upon a Provisional Application Registration No. 36,110 to Jack Lester Hansen filed 3/19/98. Field of the Invention The present invention relates to a reclamation system and more particularly pertains to reclaiming chemicals from scrap tires through convection, conduction and radiation to extract usable gas, oil and carbon black. Description of the Prior Art The use of heating and reclamation devices is known in the prior art. More specifically, heating and reclamation devices heretofore devised and utilized for the purpose of reclaiming used elastomeric materials are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements. By way of example, United States Patent Number 4,090,054 to Heine et al discloses a preheating apparatus for foundry ladles. United States Patent Number 5,316,708 to Drews discloses a method for making products made from recycled vehicle tires. United States Patent Number 5,395,404 to Burckhalter discloses an apparatus for heating whole tires in a pressure vessel. United States Patent Number 5,733,943 to Doan discloses street signs and other products and method for making same from used rubber tires. Lastly, United States Patent Number 5,800,754 to Woods discloses building materials from recycled tires. While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a tire reclamation system that allows reclaiming used elastomeric materials. In this respect, the electro-smokeless extraction/recovery system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of reclaiming chemicals from scrap tires through convection, conduction and radiation to produce usable gases, oil, solvents, and carbon black. Therefore, it can be appreciated that there exists a continuing need for a new and improved extraction chemical reclamation system which can be used for reclaiming chemicals (non-renewable natural resources, elements, etc.) from scrap tires and waste (farm waste, hazardous medical waste, etc.) through convection, conduction and radiation to produce usable gases, oils, solvent chemicals, and carbon black. In this regard, the present invention substantially fulfills this need. SUMMARY OF THE INVENTION In view of the foregoing disadvantages inherent in the known types of heating and reclamation devices now present in the prior art, the present invention provides an improved tire reclamation system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved waste, tire, chemical reclamation system and method which has all the advantages of the prior art and none of the disadvantages. To attain this, the present invention essentially comprises a new and improved electro-smokeless extraction/recovery system for converting waste and shredded tires to carbon black and fluid discharge of oil and solvent and gases and chemicals. In the preferred embodiment, a reaction vessel is formed with a generally cylindrical side wall and a bottom plate. The bottom plate has a plurality of heat apertures and a plurality of drain apertures there through. The vessel also has an open top for the receipt of waste and shredded scrap tires. A lid is provided and is adapted to be removably placed over the top with sealing bolts for the purpose of sealing the reaction vessel to allow for pressurized heating in the absence of oxygen, a combustion making gas. A plurality of hollow sheaths are formed of a thermally conductive material. Each sheath has spaced concentric cylindrical side walls, a closed top, and an open bottom positioned in sealing relationship with the heat apertures and a space extending upwardly therefrom to a location adjacent to the top. A plurality of electrical heating elements are provided within the sheaths and positioned through the open bottom of the sheath. Each heating element or tube is comprised of a hollow cylindrical rod with heating coils inside. Baffles are positioned between each heating tube at an angle of about 45 degrees to equally reflect heat and equalize the heat. Spaces allow for the full flow of heated air. Each heating element is adapted to heat adjacent waste and shredded scrap tires through the sheath by conduction through the transfer of thermal radiation energy from the sheath through the waste and shredded scrap tires in the vessel, convection through the flow of heated air and gas flow between the inter- particle spacing between the waste and shredded scrap tires in the vessel, and radiation across the space between shredded tires in the vessel. Each heating element may be vertical, perpendicular to the bottom blate, but is preferably slated into a spiral configuration and adapted to operate at between about 200 and 3,000, preferably about 1,700, degrees Fahrenheit at between about 1 psi and 20 psi, preferably about 10 psi, for between about 15 and 60, preferably 40, minutes. The times and temperatures are selected for any particular application. Next provided are a plurality of hollow drains. Each drain has spaced concentric cylindrical or oval side walls and a top. Each channel and/or drain pipe also has an open bottom positioned in sealing relationship with drain apertures. Openings are provided on at least a portion of the side walls of each drain. The openings extend upwardly from the bottom plate to a location adjacent with spaced baffles within each drain to the top to effect the flow of fluid discharge from the reaction vessel. Support means are provided for the reaction vessel. The support means are provided with pivot pin for optionally adjusting the angular orientation of the reaction vessel. There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.

DESCRIPTION OF THE PREFERRED EMBODIMENT With reference now to the drawings, and in particular to Figure 1 thereof, the preferred embodiment of the new and improved tire reclamation system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. The present invention, electro-smokeless extraction/recovery system is comprised of a plurality of components. Such components in their broadest context include a reaction vessel, a plurality of hollow sheaths, a plurality of electrical heating elements, and a plurality of hollow drain members. Such components are individually configured and correlated with respect to each other so as to attain the desired objective. The present invention essentially comprises a new and improved electro-smokeless extraction/recovery system for converting waste and shredded tires to carbon black and fluid discharge of oil and solvent and gases and chemicals and steel, such being done, preferably with zero air emissions. In the preferred embodiment, a reaction vessel 12 is formed with a generally cylindrical side wall 14 and a bottom plate 16. The bottom plate has a plurality of heat apertures 18 and a plurality of drain apertures 20 there through. The vessel also has an open top 22 for the receipt of waste and shredded scrap tires. A lid 24 is provided and is adapted to be removably placed over the top with sealing bolts 26 for the purpose of sealing the reaction vessel to allow for pressurized heating in the absence of oxygen, a combustion making gas. A plurality of hollow sheaths 28 are formed of a thermally conductive material. Each sheath has spaced concentric cylindrical side walls 30, a closed top 32, and an open bottom 34 positioned in sealing relationship with the heat apertures 18 and a space extending upwardly therefrom to a location adjacent to the top 32. A plurality of electrical heating elements 36 are provided within the sheaths and positioned through the open bottom of the sheath. Each heating element or tube 36 is comprised of a hollow cylindrical rod with heating coils inside. Baffles 39 are positioned between each heating tube at an angle of about 45 degrees to equally reflect heat and equalize the heat. Spaces 41 allow for the full flow of heated air. Each heating element is adapted to heat adjacent waste and shredded scrap tires through the sheath by conduction through the transfer of thermal energy from the sheath through the waste and shredded scrap tires in the vessel, convection through the flow of heated air and gas flow between the inter- particle spacing between the waste and shredded scrap tires in the vessel, and radiation across the space between shredded tires in the vessel. Each heating element may be vertical, perpendicular to the bottom plate, but is preferably slated into a spiral configuration and adapted to operate at between about 200 and 3,000, preferably about 1,700, degrees Fahrenheit at between about 1 psi and 20 psi, preferably about 15 psi, for between about 15 and 60, preferably 40, minutes. The times and temperatures are selected for any particular application. The distance between the sheaths containing the heating elements is between 2 inches and 24 inches, preferably 10 inches. The size of the mass of material to be heated is preferably between 500 pounds and 2,000 pounds, preferably 1,000 pounds. Next provided are a plurality of hollow drains 38. Each drain has spaced concentric cylindrical side walls 40 and a top 42. Each drain also has an open bottom 44 positioned in sealing relationship with drain apertures. Openings in the form of screens are provided on at least a portion of the side walls of each drain. The openings extend upwardly from the bottom plate to a location adjacent to the top to effect the flow of fluid discharge from the reaction vessel. A screen cylinder 46 is located at the center of the vessel. Support means 50, as shown in Figure 6, are provided for the reaction vessel. The support means are provided with pivot pin 52 for adjusting the angular orientation of the reaction vessel and holding it in such orientation for a particular application. As shown in Figures 7 and 8, an alternate embodiment of the invention is formed wherein the heating elements 56 are essentially cylindrical and spaced from each other and drain members 58 are essentially cylindrical and spaced from each other. The preferred spacing between heating elements is between about 2 inches and 24 inches, preferably about 10 inches, from each other. This embodiment employs heating elements and drain members in a triangular configuration to match the triangular configuration of the reaction vessel 60. This arrangement maximizes the heat output in a flat walled reaction vessel. The embodiment of Figures 9 and 10, the third embodiment or second alternate embodiment, features heating elements 64 which are essentially cylindrical and the drain members are screens 66 configured to hold the waste and shredded scrap tires in an essentially cylindrical configuration around the heating elements. Drains 68 are located in the base of the housing beneath the screened areas 70. Figure 11, the fourth embodiment or third alternate embodiment, relates to an embodiment wherein the heating elements 74 are cylindrical with generally rectilinear sheaths 76 receiving the heating elements. This construction with heating elements within sheaths allows for the removal, repair and replacement of heating elements without opening the reaction vessel. The drains are screens 78 in a rectilinear configuration with drains there beneath. Figure 12, the fifth embodiment or fourth alternate embodiment, employs drain members 82 as cylinders and heating members 54 in sheaths 86. The heating elements and drain members are spaced and parallel with respect to each other. They extend from edge to edge of a cylindrical reaction vessel 88. The rectilinear configuration is the simplest to fabricate. As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
