Abstract

1,111,387. Extracting liquid from slurry. G. A. HARVEY & CO. (LONDON) Ltd. 5 April, 1965 [10 Jan., 1964], 1206/64. Heading BID. . Liquid is extracted from a slurry or suspension by passing the mixture along an annular chamber defined by a barrel member 8 enclosing a worm member 6, the barrel and worm having respective helical grooves 12, 10 whose threads are of opposite hand and which vary in depth in opposite senses along the chamber, portions of the chamber walls being porous for extraction of liquid therethrough by pressure under which the mixture is delivered to the device. As shown, the barrel and worm each have additional helical grooves 14, 16 which are covered by porous metal ceramics or plastics elements (18) (Fig 2 not shown) and which communicate by holes (24), 20 with liquid outlet (22) (Fig. 3, not shown) and hollow interior 17 of worm 6. As shown, the worm is rotated by motor 40 within stationary barrel 8, but the barrel alone could rotate, or both worm and barrel could be fixed or rotate. Heating and/or cooling jackets may be provided. The barrel and worm narrow at the solids discharge end, and grooves 14, 16 stop short of that end, which is closeable by a plate 33 moved by rams 36. Initially, plate 33 is held against end 38 of barrel 8 as shown, while mixture is delivered to inlet 52. Once pressure has built up, plate 33 is withdrawn rightwards and solids are discharged from the right hand end 38 of the barrel. Liquid extracted is either discharged at outlet 53, together with any fluid from seal 50, or by resetting a valve (Fig. 2, not shown) the liquid may pass through conduit 30 and a corresponding central hole through shaft 34 to which suction is applied. Solids removed from one device may be mived with fresh liquid and delivered to another similar device. A screw 48 is provided for axial adjustment of worm 6 within the barrel, whereby the radial spacing between the crown portions of worm and barrel is varied.
