Abstract: Apparatus comprising at least one rotatably driven drum having a circumferential filter medium adjacent which pressurized liquid suspension containing fibrous material is supplied in the rotary direction of the drum driven rotation. One or more baffles, having low friction material on their surfaces opposing the filter medium, are resiliently biased by pressurized liquid and/or mechanical biasing means to gradually converge towards the filter medium in the rotary direction of the drum driven rotation, and fibrous material collected on the filter medium may be washed by either the biasing liquid or separately supplied pressurized liquid. Also, a method for processing a suspension containing fibrous material through the employment of such an apparatus.

Abstract: A continuous drum vacuum filter wherein the drum, rotatable about its axis, has on its working surface cells whose external sides are formed by a filtering material. The cells are connected by means of ducts to the movable part of a valve installed coaxially with the drum and serving to connect the cells in the required sequence to suction and compressed air lines during rotation of the drum. The fixed part of the valve has an overflow channel so ensuring communication of a cell emerging from the suspension with a cell submerging into the suspension that overflowing of the filtrate from the former cell to the latter is ensured.

Abstract: 1,211,765. Filter. IMPROVED MACHINERY Inc. 9 Dec., 1968 [29 Dec., 1967], No. 58330/68. Heading B1D. A filter, for thickening wood pulp suspension, comprises a cylindrical perforate drum 11, located in a housing having an inlet 7 and an outlet 8 upstream of the drum and a filtrate outlet 9 downstream, the drum being cleaned by relatively rotating means which induces reverse flow and is followed by means which limits subsequent filtrate flow, to prevent immediate re-clogging of newly cleaned drum surface. In Fig. 2, drum 11 rotates, together with radial partitions 30 which divide its downstream surface, an arcuate baffle wall 24, pivoted at 26 and adjusted at 27, creates reverse flow adjacent outlet 8 by virtue of the drum and baffle wall 24 converging in the direction of drum rotation. A similar baffle wall 34, adjacent inlet 7, diverges from the drum to limit filtrate flow adjacent the inlet. The annular space 42, 10 outside the drum increases in width from inlet 7 to outlet 8 and is so dimensioned that incoming liquid in portion 42 assumes the same peripheral speed as the drum. This construction could be reversed, with outward flow of filtrate through the drum, and partitions 30 and baffle walls 24, 34 located outside the drum. In Figs. 3, 4 (not shown) the drum is fixed, filters by inward flow, and encloses a pair of rotary baffles (83), each of which has a leading portion converging towards the drum, to induce reverse flow cleanings, and a trailing portion diverging from the drum, to limit subsequent filtrate flow. Liquid flow round the outside of the screen may be in the same direction as or opposed to the baffle rotation, openings (85, 86) each serving as inlet or thickened suspension outlet. The baffle 23 in Fig. 2 could be replaced by a nozzle directing reverse flow liquid on to the screen, or both baffles 23, 33 could be replaced by a roller rotating about an axis parallel to that of the drum and having axial slots engaging partitions 30.

Abstract: The invention is a development of the apparatus of Specification 982425, the new features being (a) two concentric sets of filter tubes, those in one set being staggered in relation to those in the other set; (b) a central tubular member extending through the outlet chamber and providing communication from the inlet end of the housing to the other end; (c) the provision of bearings for the back-wash tube at both ends of the housing, the backwash tube extending through the above-mentioned tubular member; (d) the provision of two hollow radial arms of unequal length extending from the back-wash tube at each end of the outlet chamber, the longer arm communicating with the outer set of filter tubes and the shorter with the inner set, at each end. Thus each filter tube is open at both ends, and during back-washing filtrate and residue are discharged from both ends simultaneously.

Abstract: 1,065,850. Filters. UNITED STATES STEEL CORPORATION. Dec. 30, 1963 [Dec. 31 1962], No. 51210/63. Heading BID. The filter cake picked up as hollow, vacuumleaf filters rotate and dip into the slurry in a tank 10 is heated uniformly by arranging heating units, each operated at equal intensity and arranged in arcuate rows on each side on the outside of hoods 21 which cover a portion of each leaf filter above slurry level. The number of rows is sufficient to present a substantially solid front of heating units at the lower edge of each hood, there being a single heating unit in the innermost row, and the number of units in each succeeding row increasing by one. A plurality of leaf-filters are carried by and rotated by a shaft 15. The dried filter cake is blown off the filter into a shoot 18 by a blower 16 acting on the sector 17 of the leaffilter. The remainder of the space within each filter being under vacuum. Scrapers 20 which assist in removing the cake, and splash guards 19, may also be provided.
