ABSTRACT:
A filter screen assembly for removing particulate material from a slurry. The assembly includes filter media for accumulating particulate of larger than predetermined size as filter cake exteriorly of plates having a plurality of slots therein. A hook member along an edge of each of the plates engages a tubular distributor having slots therealong. Each of the slots of the tubular distributor receives the hook member of one of the plates so that the plates are mounted on the tubular distributor. Other edges of the plates are connected to form chamber means therebetween. The chamber means communicates with the interior of the tubular distributor. A reduced pressure is impressed on the interior of the tubular distributor to cause liquid of the slurry to be drawn through the slots in the plates so that the particular material collects on the outside of the plates.
