ABSTRACT:
A filter press plate for layer and settling filters having an open frame of stainless steel and at least one partition plate of corrosion resistance material detachably supported within the frame by means of cooperating lugs and recesses on the mutually facing edges of the at least one partition plate and frame, sufficient clearance space being provided between the peripheral edge of the at least one partition plate and the adjacent frame edges as to accommodate any difference in the heat expansions thereof at the maximum temperature to which the filter press plate is to be exposed. The frame includes exteriorly projecting hollow eyes which define manifolds for supplying and removing the liquid to be filtered when a plurality of the elements are stacked together in use. The at least one partition plate is profiled on its opposite side faces to form channels for the liquid being filtered. For large size elements, the frame includes internal struts extending between opposite sides and defining a plurality of internal areas, each having a plate detachably supported therein.
