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 particulate material collects on the outside of the plates.

A filter screen assembly for removing particulate material from a slurry which comprises a pair of filter plates each having a respective hook member along a first edge of the plate, a tubular distributor having slots therealong, each of the slots of the tubular distributor receiving the hook member of a respective one of the plates so that the plates are mounted on the tubular distributor, means for closing one end of the tubular distributor, each of the filter plates having a plurality of separator bars oriented transversely of the first edge thereof to cooperate with opposed separator bars of the other plate to effect offsetting transfer of compression forces on the plates, means for connecting other edges of the plates to form chambers therebetween extending toward the first edges of the plates, means forming a passageway communicating between each chamber and the interior of the tubular distributor, there being slots in the filter plates extending transversely of the chambers, and means for impressing a reduced pressure on the interior of the tubular distributor to cause liquid of the slurry to be drawn through the slots of the plates, the removed particulate material collecting on the outside of the plates.
