ABSTRACT:
A filter press provided with a spray cleansing device of the kind described in U.S. Pat. No. 4,107,042 granted Aug. 15, 1978 to wash filter plates of the press disposed in a stack on horizontal guides in which the spray device comprises a support frame which moves along the stack of plates on the horizontal guides. Two branch conduits of the device are fitted with nozzles and surround a plate being washed to spray wash the plate simultaneously from both sides. The specific improvement in the present invention comprises a novel spray water catch basin which has a width more than twice the spacing between the branch conduits. Movable segments on both sides of the catch basin are provided which may be pivoted about a perpendicular axis to adapt the catch basin to many locations along the filter press. The important difference is the fact that at least the edge portions of the catch basin are movable in a horizontal direction relative to the vertical area of the frame of the washing device to provide a beneficial advantage over our prior patent. A new suspension is also provided for the catch basin which is adapted to the movement of the segments.
