RENDERING TANK.
Application led July 1, 1918, Serial No. 242,768. 'Renewed February 6, 1922. Serial No. 534,581.
To aZZ whom it may concern:
Be it known that I, WILLIAM LIsTER, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illlnois, have invented certain new and useful Improvements in Renderin Tanks, of which the following is a full, c ear, and exact specification.
My lnvention is concerned with rotary rendering tanks of the general character shown in the application of Lister No. 17 3,- 734, filed June 9, 1917, and is designed to provide such a tank with a steam jacket and Various other improvements 'so that it can be used more economically and Yexpeditiously in carrying out the various rendering processes for which such tanks are em loyed.
o illustrate my invention, I annex hereto five sheets of drawings in which the same reference characters are used to designate identical parts in all the figures of which- Fig. 1 is a side elevation of a tank employing my im rovements with the connecting pipes associated therewith illustrated some.
what diagrammatically;
Fig. 2 is an end elevation with parts broken away and as seen from the left-hand end of Fig. 1, and as showing the driving gearing which is omitted in F ig. 1;
Fig. 3 is a central longitudlnal vertical section;
Fig. 4 is an enlarged view of the pipe connections seen at the left-hand end of Fig. 3 but on a larger scale;
Fig. 5 is a similar view of the connections seen at the right-hand end of Fig. 3; and
Fig. 6 is a. detail of the elements associl ated with Fig. 4 but on a somewhat smaller scale. 1
As a support for the tank in its preferred form, I employ the three columns 10 on one side, each of which is surmounted by the bearing bracket 11 for the rooved antifriction roller 12 journaled t erein, which rollers co-operate with the three supporting rings 13 which are secured to the periphery of the tank in the manner which will be described. At the other side of the apparatus, I emfploy the two smaller basel elements 14 which have secured thereon the bearing brackets 15 for a shaft 16, which Ashaft 16 has secured thereon the three grooved supporting and driving rolls 17 In line with the base elements' 14 is the larger base elenaled in the bearings 22 secured on top of the bearing brackets 20 supported on the base 18 1s provided at its outer end with `a belt ulley 23 by which the shaft is driven and it as secured thereon between the bearings the worm 24 which meshes with the worm gear 25 secured on the'outer end of the shaft 16. It will be noted that the three supporting rolls 12 on one side of the tank are much hi her than the similar supporting driving rol s 17 on the other side of the tank, and as a consequence a considerable portion of the weight of the tank rests on the rolls17 so that the rotation of the shaft 16 serves to rotate the tank by the friction of the rolls 17 with the rings 13.
The tank is composed of the inner cylindrical body portion 26 which has riveted to the ends thereof the preferably concaved 'circular heads 27 and 28. Surrounding the inner shell or tank proper is the jacket which is made up of the cylindrical body portion 29 spaced apart from the body portion 26 a suitable distance and having riveted to the ends thereof the preferably concaved circular heads 30 and 31. The rings 13 have the general contour of a railroad rail but with a very wide base 32, through which base at suitable intervals are passed the supporting bolts 33 which pass through the shells 29 and 26 into which they are threaded and the rails 13 are secured in the desired position of adjustment by the lock nuts 34 co-operating with the outer face of the bases 32 of the rails or rings 13.
In order in some cases to supply treating iuids to the contents of the tank and in other cases to draw ofi the fluid contents of the tank, I locate in the tank a horizontal perforated pipe 35 which extends along the length of the tank near its bottom, when the tank is in the position shown in Fig. 3, and is secured from movement in the tank by any suitable means, and the position of which is indicated on the exterior of the tank by some suitable indication, preferably by placing it in .alignment with the external lug 36 to be subsequently described.
This pipe 35 is connected by an elbow 37 with the radially extending pipe 38 which 1s connected at its other end by the union 39 with an elbow 40 secured to a horizontal pipe 41 which is central of the tank and ex' tends out through the stuffing boxes to .be described and terminates, as shown 1n Fig 6, in a stationary pipe 42 shown 1n Flg. 1 as connected by suitable short plpes 43 and elbows 44 with a header pipe 45 to which 1s connected the five pipes 46, 47, 48,49'and 50, each of which pipes is provided wlth a shutf off valve 46, 47 a, 488L 49a and 50, and lWhlch pipes are convenienti ly to a point for the ischarge of Waste gas; to a live steam supply; toa grease discharge tank; to a glue discharge tank; and to a hot water supply. Associated wlth the pipe 46 is a pressure gauge 46b which serves to show the pressure in the tank for the various purposes for which an accurate knowled e of the pressure is needed. Associated wit the pipe 5() is a test cock 50b from which a sample of the contents of the tank as they would be delivered through the pipe 35, 41, etc., can at any timel be taken. The plpe 42 terminates in a stufiing box l'whichhas associated therewith the adjustable head 52 bywhich the stuffing, not shown, can be put under the desired pressure. With the rotating pipe 41 passing through the. stuffing box into the stationary pipe 42 1t will be obvious that no leakage will occur 1n the passage of the fluids from the rotating pipe to the stationary pipe. y
At the same end of the tank I employ means for supplying steam or compressed air to the interior of the tank at its top or for exhausting the pressure at the top of the tank, irrespective of the position to which it may be rotated, and for this purpose I have the pipe 53, provided with suitable perforations 54 in the upper end thereof extending from the highest position inside the tank radially down to the center of the adjacent end of the tank, where the pipe 53 terminates in an annular enlargement or sort of a hub 55 which is screwed onto the threaded end of the stationary sleeve 56, best seen in Fig. 4, which has its outer end closed by the cap 57 screwed therein. Associated with this cap 57 is a stuffing box 58, which may be of any desired construction, and which is employed to prevent leakage in spite of the rotation of the tube 41 therein. The outer end of the sleeve 56 has threaded therein in suitable bosses a pipe 59 on the upper side which is connected to suitable means for supplying steam or compressed air, as may be desired, and similarly secured in the under side is a pipe 60 which is connected with suitable means for exhausting the air or gases from the interior of the tank. The head 3() has bolted thereto the Stuiiing box bearing 6l which rotates about connected respective- 62 in said sleeve, and consequently there is free communication through this stationary sleeve 56 either by the pipe 59 or 60, and the pipe 53 to the top of the tank. To prevent leakage from the interior of the tank to the interior of the sleeve 56, 1 provide the stationary inner sleeve 63, which has its outer end entering a recess 64 inthe cap 57 and engaging a gasket 65 in said recess. The inner end of the sleeve 63 is provided with a head 66 which is screwed into the internally threaded end of the sleeve 56, and which serves to hold the pipe 53 in place as Well as to close the end of the sleeve 56. The head 66 is provided in the flange 67 with the recesses 68l by which the necessary wrench can be applied to screw the sleeve 63 into place. At the same end of the tank, I preferably employ the circular, preferably concaved, shield 69 through the center of which the pipe 41 passes, and which terminates short of the central cylinder 26, to which it is secured at suitable intervals by the angular pieces 70 riveted at their ends to the shield and cylinder Y' respectively. This shield 69 serves to keep the solid materials in the body of the tank from engagement with the pipe 53 ,and the bearing at the center, and this promotes thedurability of the apparatus.
Secured on the inner Wall of the shell 26 are preferably provided suitable veins or blades 71 which serve to lift the material in the tank as it rotates.
At the other end of the tank, 1 provide a short pipe 72, provided With suitable perforations, and passed by suitable liquid tight connections through the shells 28 and 31 into the boss 73 secured on the'exterior of the head 3,1. This boss 73 has a passage therethrough and has the radially extending pipe 74 connected thereto and connected by the union 75 with a passage 76 in a small head 77 secured to the center of the outside of the end 31. The pipe 74 is provided with cock 78 by which it can be opened or closed, as desired, and the associated pipe 72 is preferably located diametrically opposite in the tank to the pipe 35, so that the position of the boss 73 or the boss 36 serves to show at any time the location of the 'pipes 72 and 35. On the other side of the head 77 is a passage 78 which is connected by the union 79 with a pipe 80 which opens into the previously mentioned boss 36, which is secured to the end piece 31 and has an opening through said end piece so that the pipe 8O can thus be connected to the steam jacket surrounding the tank proper. A cock 81 located in the pipe enables me to shut it olf as may be desired and. I may here state that the purpose of th1s pipe is to free 'the jacket of the watery of condensation of the steam supplied thereto. The head 77 has projecting centrally therefrom the outer sleeve 82 and the inner sleeve or pipe 83, the two sleeves forming between them an elongated annular passage 84 connected to the passages 7 6 and' 78. head 85 is held in place by the pipes 86 and 87 screwed into suitable bosses formed in the top and bottom of the head and the outer side of the head is provided with the small stulling box 88 through which the sleeve 83 passes and in which it rotates. It will be noted that the sleeve 83 serves as a pipe leading from the steam jacket, and it will be understood that the outer end of this pipe 83 is connected by a stuffing box such `as is shown in Fig. 6 to a stationary pipe connected with a suitable supply of live steam for use in the steam jacket when desired. The head 85 has on the inner face of it, the body 89 of -a large stung box screwed into it, and th1s stationary stufling box prevents the escape of fluids from the central cavity 90 of the head 85 through the space between the rotating sleeve 82 and its stationary bearing. To close the end of the sleeve 82 and secure an adequate bearing against the end of the stuffing box 89, I screw into the internally threaded end of the Vsleeve 82 the nut 91, open at its center, and having the flange 92, between which flange and the end of the stuffing box 89, I place the two flat bearing rings 93 and 94. The nut 92 is provided with suitable recesses 95 so that a wrench can be applied thereto. The pipe 87, previously mentioned, is employed to discharge the water of condensation and is provided with a suitable connecting pipe 96 and a shut-off valve 97 which leads to any suitable discharge for the said water condensation. The pipe 86 is connected to a suitable header pipe 98, to which is preferably connected the four pipes 99, 100, 101 and 102, each of said pipes being provided with an associated stop cock 99a, 1001, 101a and 1022*, and the pipes being for ordinary use preferably connected respectively with a hot water supply; a cold water supply; a steam supply; and a compressed air supply.
The use of mynovel rendering tank will be apparent to those skilled in the art. The employment of the steam jacket enables me to reduce materially the amount of time required in those steps which involve the evaporation of water and the drying of t-he residues, and the ability to draw off vapor by a vacuum also contributes to this result. All ordinary rendering processes can be carried out by my tank rapidly and in a sanitary manner.
While I have shown and described my invention as embodied in the form which I at present consider best adapted to carry out its purpose, it will be understood that it is capable of modifications, and that I do not desire to be limited in the interpretation of the following claims except as may be necessitated by the state of the prior art.
