Abstract

867,690. Rotary filters. GENERAL ENGINEERING CO. A.B. June 17, 1959 [June 26, 1958], No. 20871/59. Class 46. [Also in Group XXVIII] A drum 5 rotating in a counterclockwise direction has the residue removed from the portion of its surface lying between a roller 30 and a scraper 29 by back-flowing filtrate 26. The wet residue is discharged along a tube 27 which extends through a wall of the filter casing 1 and is slotted (at 28) as shown only within the casing. The pressure differential of discharge is governed by a valve (not shown) in the tube 27. The roller is resiliently mounted about pins 33 by springs 34 and scraped by the leading edge 37 of the slot 28 in tube 27. In Fig. 1 (not shown), the drum is driven from one end by a stub axle and supported at the other by engagement of a flange projecting from its end plate in an elastic seal surrounding the filtrate pipe. The drum may be outward-flow instead of inward-flow, in which case the residue-removing apparatus is inside the drum.
