Abstract

957,622. Presses for separating liquids from solids. STOCKDALE ENGINEERING Ltd. June 5, 1962 [June 6, 1961], No. 20331/61. Heading B 1 D. A rotary vacuum filter for sludge comprises a perforated drum A mounted on a rotating shaft A<SP>1</SP> and divided into four compartments by radial walls, Fig. 1, a plurality of endless tapes, or cords, b extending around the drum A and drums b<SP>1</SP>, b<SP>2</SP>, and a plurality of vibrating rollers B which compress the sludge collected by the cords b from a trough C. The moisture expelled from the sludge is sucked into the drum. The rollers B may be vibrated against the action of spring d', Fig. 3, by an electrically operated vibrator D<SP>3</SP>. Alternatively, the rollers may be vibrated by pistons actuated by fluid, e.g. air, and attached to both ends of each roller, Fig. 2 (not shown), the flow of fluid to cylinders containing the pistons is controlled by a cam operated valve, flow regulators and pressure reducing valves. Suction is applied to the drum through apertures a<SP>1</SP>, a stationary chamber a<SP>3</SP>, Fig. 3, provided with seals as shown, and a pipe a<SP>2</SP>. Deliquidified sludge is discharged from the tapes b into a receptacle C<SP>1</SP>.
