Abstract

975,663. Filter press plates. J. A. JOHNSON. Dec. 21, 1962 [Nov. 24,1961], No. 42025/61. Heading B1D. At least some of the faces of the trays in a filter press are fitted with contoured grids, the grids having apertures covered by a filter cloth. Filter cakes, e.g. of ceramic material, formed between the trays, are thus formed with inherent lines of weakness along which they are easily separatable into a number of blanks or billets. All trays in the press may have a grid on one face only, or alternate trays may have grids on both faces, or all trays may have a grid of half-depth fitted on both faces. In one embodiment, Fig. 1, filter trays 10, having thicker frame portions 13, are fitted on one face with contoured grids 12, the grid defining a number of apertures 15, Fig. 4. Under filtering pressure, cloth 11 takes up the contour of the grid so that the filter cake is similarly contoured. A wire mesh or perforated grid may be interposed between the faces of the press tray and the contoured grid of the invention. Specifications 795,167, 820,668, 842,669, 842,795, 883,595, 888,340, 927,697, 937,669 and 975,662 are referred to.
