ABSTRACT:
A chamber filter press including frameless chamber plates covered on both sides with filter clothes stretched thereover, wherein two adjacent chamber plates contact each other with an outer, continuous clamping rim and define a filter chamber, consisting of a central filter cake compartment lying between the filter cloths and two outer filtrate compartments lying between the plate and the filter cloth. Repressing devices for the filter cake are arranged in the zone of at least one of the two filtrate compartments of each filter chamber. The repressing devices are fashioned as distensible cushions suspended within at least one filtrate compartment of each filter chamber at the adjoining chamber plate by marginal suspension strips which keep open, at least at the lower edge of the distensible cushion. A liquid passage is provided between the half of the filtrate compartment on the filter cloth side and the half on the plate side.
