OIL-EXT-RACTING APPARATUS.
Specication of Letters Patent. i .Patentd am, '2" 1911,
Application led January 31, 1910. Serial No. 541,203.
To all whom it my concern: 4 Be it known that we, CHARLES TURNE and RICHARD F. SCHROEDER, citizens of the United States, and residents of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Oil-Extracting Apparatus, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.
The invention relates to devices for eX- tracting oils from solids, such as meats, fish, garbage, etc.; its object being to provide for rapid and continuous action upon the material from which the oil is to be extracted by means of a solvent and from which the solvent taken up by absorption may be recovered, and it consists in a structure such as is hereinafter described and as illustrated inthe accompanying drawings,
in Which- Figure 1 is a erspective view of the machine, a portion eing broken away, showing the internal construction; Fig. 2 found in part upon each of two sheets of the drawings, is a longitudinal, vertical section; Fig. 3 is a vertical section on the vline 3 3 of Fig. 2; Fig. 4 is asectional detail of a portion of a pipe or cylinder through which the solid material is passed for treatment, and
showing the arrangement of pipes for introducing a dissolving agent; Fig. 5 is a sectional detail of a retarding device which may be mounted Within the cylinder; and Fig. 6
' is a detail ofthe delivery end of the cylin-v der showing a modified form of construction.
The device comprises, generally speaking, V
a cylinder here shown as horizontal throughout its entire length, and through which the material is driven by means of screw conveyers; a receptacle for the oil liberated by the dissolving agent, that section of the cylinder located within the receptacle being perforated; means for introducing a solvent,
such as gasolene, into the material when occupying the perforated section of the cylinder; means for introducing l'a vaporizing agent, such as steam, into the material after it has passed beyond.tlie receptacle, the pory. tion of the cylinder then occupied by the material being perforated to permitthe escape of the vapors and liquids; sectional screw conveyers revolving within the cylinder for advancing the material therethrough and impacting it at either side of the sections of the cylinder within which it is acted upon by the solvent and the vaporizing agent; and means for introducing into the cylinder these agents; together with other incidental features as hereinafter pointed out.
The cylinder, through which the material to be acted upon is passed, is as a whole designated 10. Adjacent one end thereof there is provided a hopper' 11, for receiving the material', and adjacent its opposite end there is provided a discharge nipple 12. A shaft 13 extends entirely through the cylinder and is located upon the axis thereof and is suitably journaled in en d plates 14, 15, and carries a pulley 16 by means of which it may be turned. AA spiral or screw conveyer 17 is mounted upon the shaft 13 and extends under the hopper 11, and terminates a little shortof the section 18 of the cylinder within which themate'rial is acted upon by the solvent, this latter section being located within a tank 19 for receiving the liquids drained off. A second spiral or screw conveyer 20, xed upon the shaft 13, is located within the section 18 of the cylinder,
and moves the material therethrough, delivering it to a third section 21 of the cylinder within which it is to be treated by the vaporizing agent, this section being located within a tank 22. The material is then taken up and advanced by a third spiral or screw conveyer 23 and moved to the discharge end 24 of the cylinder, where it is delivered to the nipple 12. The sections 18 and 21 of the cy inder 10 are freely perforated to permit the escape of vapors and liquids. Y
The dissolving agent, such as gasolene, is introduced into the section 18 of the cylinderby means of a pipe 25 leading from aV suitable source 0f supply and entering the tank 19 through branches 26, 27 provided with suitable valves, as indicated at 28, 29,
these branch pipes each communicating with pipes as 30, 31 and 32 33, which he along the sides of theV cylinder sect-ion 18 and communicate with the interior thereof through a plurality of nipples, as shown at 34. An additional suppl of the solvent may be introduced througli the shaftA 13, which is shown as tubular for this purpose .and as having eduction ports 35 opening to the cylinder section 18. The solvent is introduced into the tubular shaft through a branch pipe 36 in swiveled engagement with the end of the shaft through a stuiiing box 37. A plug -der and may be provided with one or more cups, as 41, from the bottom of which drainpipes 42 lead tothe exterior of the tank and are provided with valves, as 43, supplying means for testing the operation of. the apparatus. The liquid contents of the tank 19 may be drained off through a pipe 44.
As the material passes on from the cylinder section 18, it holds by absorption some of the solvent, and this is evaporated out of it within the cylinder section 21 located Within the tank 22. For this purpose steam is introduced into the cylinder section 21 by means of a pipe 45 leading from a suitable source of steam pressure and entering the tank 22 through the branches 46, 47, which discharge into the cylinder through pipes which may be constructed and arranged like the pipes 30 to 33 and which are therefore not shown in detail in the drawings. An additional supply of steam may be delivered to the cylinder section 21through the shaft 13, a steam pipe 48 being in swiveled engagement with the end thereof through a stuiiing boX 49. The hot steam'causes the evaporation of the liquid held bythe material, the vapors escaping through the eduction ports 50 of the cylinder section 21 into the tank 22, from which they may escape through a pipe 51 which leads to a suitable condenser (not shown). Any liquids dripping from the cylinder section'21 or resulting from condensation of the vapors within the tank 22, are retained by this tank and may be discharged therefrom through a suitable pipe, as 52. Passing beyond the cylinder section 21 the material reaches 'the discharge nipple 12. The rate of discharge of the material may be regulated by means of a valve 53 slidably mounted on the shaft 13 and movable toward and away from the end of the cylinder, a lever 54 providing means for shifting this valve.
When the apparatus is used for treating "garbage or other material normally containing moisture and which has not been previously thoroughly dried out, the receiving end of the cylinder 10 may be inclosed within a steam jacket 55 to -which steam is led through a suitable pipe 56 and from which water of condensation may be discharged through a suitable pipe 57, the
detaches the material from the forward end of the plug thus formed and moves it on Ethrough the cylinder section 18 as a loose and open mass into which the solvent may readily pass, and delivers it into that ortion of the cylinder between the sections 18 and 21 within which there is located no conveyer. There it again becomes impacted .and forms a plug through which the solvent will not flow, and also prevents the steam with which the material is next treated from passing backwardly into thevcylinder section 18. The conveyer 23Y detaches the inaterial from this impacted mass and moves it forward through the cylinder section 21 in a sufficiently loose condition to permit the passage into it of the steam there introduced for the purpose of eliminating the solvent and oils which may have been held by absorption. As the conveyer 23 terminates short of the delivery end of the cylinder, the material again becomes impacted to a suilicient extent to prevent any loss of vapors, and the density of the plug here formed may be regulated by means of the valve 53. It may be found desirable to provide means for choking the cylinder passage at each side of the section 18 for the purpose of more densely impacting the material to prevent the escape therethrough of vapors and liquidsand when such choking is found to be necessary we employ truncated sleeves 69, 70, as shown in Fig. 1, but prefer to employ an elastically-expansible device such as that illustrated in Fig. 5 of the drawings. This device comprises a number of tapering slats or staves 58 arranged in annular series and hinged, as shown at 59, to a collar 60 which may be clamped between the flanges, as 61, 62,11niting the sections of the cylinder. The slats or staves 58 project from the collar 60 in the direction in which the material is moved', and their free .ends `are closed together by any suitable springmechanism, as shown, by means of springs 63 `coiled upon rods 64, which bear-upon the slats or staves 58 and project outwardly through caps 65 attached to the outer surface of the cylinder, the springs reacting between the ends of the caps and collars, as 66, on the rods.` A sight gage 67 is shown as vapplied to the tank 19 to indicate' the level of the liquid contents therein.
In treating the material with steam in the being spaced apart, and pipes cylinder must usually be dried before shipped as fertilizer. The apparatus may be provided With means for' completing this last step so that when discharged `therefrom it will be ready for packing, as in sacks, without further manipulation. To accomplish this purpose the end portion of the cylinder, that is to say, the portion lying between the section 21 and the discharge nipple 12, may be steam-jacketed, as shown at 71, in Fig. 6. For the purpose of carrying oftI any vapors which may accumulate Within the tank 19, a
valve-controlled pipe 72 leads therefrom to the pipe 52; and for the purpose of expelling from the tank 22 any vapors which may remain therein after the operation of the apparatus has been stopped, a steam pipe 7 3 may be led to the chamber thereof.
The method of extracting oils from solids as herein described may be practiced by other means thanthe apparatus forming the subject of this application, and such method is made the subject of our co-pending application Serial No. 541,202.
