In ventor wr/L ' Attorney Patented Aug. 5, 1930 UNITED STATES rarer ortica y GEORGE E. WILBE, or irErioair, NEW JERSEY Appli-cation filed September 4, 1929. Serial No. 390,303.
This invent-ion relates to filters and more particularly to devices of this character of the type wherein the iiltering is accomplished by means of centrifugal force, propelling or driving the fluid portions of the slip or material to be filtered through a suitable filtering material, the solid portion of said slip being retained by said filtering material.
One object of the invent-ion is to provide in a manner as hereinafter set forth a filter of the aforementioned character, having means for pr-ogressively feeding the material from which the fluid has been extracted to a point of discharge.
Another object of the invention is to provide, in a manner as hereinafter set forth, a device of the aforementioned character, wherein the movement of the material from which the fluid content has been extracted toward the point of discharge is accomplished by means of the rotary movement of the filtering element.
Other objects of the invention are to provide a device of the character set forth which will be simple in construction, strong, durable, eflicient in its use and which may be manufactured at low cost.
Other objects and advantages of the invention will be apparent from a study of the followin g specification, taken in' connection with the accompanying drawings, wherein like characters of reference designate corresponding parts throughout the several views, and wherein: The figure illustrating the invention is a View in partial vertical section, illustrating a filtering device constructed in accordance with this invention.
Referring to the drawings in detail, the reference character 1 designates generally a rotatable cylinder having a perforated cylindrical body portion or side walls 2, and oppositely extending conical end walls 3 and 4. The lower end of the conical end wall 4 f `terminates in a sleeve 5 of uniform diameter,
which rests upon the upper face of a suitable support or bracket 6 for the purpose of supporting the cylinder l. The apex of. the upper conical end wall 3 is provided Lwith a trunnion or pivot pin which projects.y upwardly to a supporting bracket 8 and has mounted on its upper -or free end, adrive pulley 9, upon which a drive belt 10 is mounted for transmitting power to the. cylinder l from a suitable source. A filtering agent or material 1l is applied to they inner periphery of the perforated wall 2 of the cylinder and is held in place thereagainst by a filter cloth 12. Extending longitudinally through the cylinder 1 is a substantially cylindrical core member or conveyor screw which is designated generally by the reference character 13.` The conveyor screw 13 is provided on the periphery with a spiraly rib 111, which extends over the entire length of the cylindrical portion of the conveyor. rlhe opposite endsk of the conveyor screwlt are provided with conical portions 15 and 16, The lower conical portion 16vis provided with a downwardly extending shank 17 which passes through the sleeve 5 and the supportbracket 6, `to which said Shanks may be secured-as byy akey for the purpose of holding the screws 13 againstrotation. A conveyorpipe 18 has one end supported in the bracket 6 and communicates with a passageway19formed inthe shank 17, which opens into thecontainer or cylinder 1, as clearly illustrated in the drawings.
, It will be apparent that the shank 17 functionsI as a means for retaining thek sleeve 5 against lateral movement upon the bracket 6. Near itsapex, the upper endwall 3 of the cylinderl is provided with an internally disposed ,web portion 20 which is providedl with ay centrally `disposed opening for the reception 'ofa trunnion 21 mounted on the conical portion 1 5, of the cylinder 13. A Vdischarge spout or pipe 22 is also mounted in the upper conicalend wall 3. As clearly'illustrated in thedrawin'gs, the outer face of the spiral rib 14: isspaced inwardly from the ltering Cloth. 12. 1 l v In-use, the slip o'r the material to be filtered is pumped from the tank, not shown, through the pipe 18 and passes into the cylinder l, through the passage 19 formed ingthe shank 17. It is to be understood,.of course, that the' cylinder 1 is being rapidly rotated, through the medium of the pulley 9 and belt 10. The supply pipe, and a discharge conduit cornrotary movement of the cylinder 1 causes the mumcatmg with the container adjacent its fluid contents of the slip to be thrown outupper end.
wardly by centrifugal force through the filter cloth 12 and the filtering material 11 and then through the perforated side walls 2 of the cylinder, in a well known manner.
The solid material which is retained in the container by means of the filtering elements 11 and 12, is carried around with the cylinder 1, which rotary movement causes said solid y material to befed upwardly and out through the discharge spout 22, by means of the rell atively stationary spiral rib 14 on the conveyor screw 13.
lt is thought that the many advantages of a filter constructed in accordance with this invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is tov be understood that changes in the de.- tails of construction may be had, which may fall within the scope of the invention as claimed. Y
VJ hat is claimed is: Y
A. filter of the character described comprising a rotary cylindrical container having side walls adapted for the passage of the extracted material, said container furtherl including conical end walls, upper and lower supporting brackets, a trunnion formed integrally on the apex portion of one of the end walls extending rotatably through the upper bracket, a drive pulley fixed on the upper end portion of the trunnionvabove the Vupper bracket, a tubular sleeve formed intions extending into the conical end walls of the conveyor, an integral trunnion on one end of the screw conveyor mounted for rotation through thebearing plate, an integral shank formed on the opposite end portion or the screw conveyor and extending downwardly through lthe sleeve and the lower supporting bracket, the sleeve adaptedfor rotation on the shank and the shank fixed to the lower bracket in a manner to retain the screw conveyor against rotation, said shank! constituting means for retaining the sleeve In testimony whereof I affix my signature.
