ABSTRACT:
An apparatus for filtering a liquid slurry is described. The apparatus uses a pair of filter chambers formed by a pair of fixed plates, and a pair of opposed moveable plates. The moveable plates are moved into engagement with the fixed plates by the downward movement of a wedge member disposed between the plates and, the plates are bias so that when the wedge member is withdrawn, the plates will be drawn together opening the filter chambers. The chambers are sealed by opposed arcuate gaskets so that the sealing action is achieved by internal pressure rather than the pressure driving the plates together. A filter media is provided on a continuous roll which extends between the gaskets and is intended to carry the filter cake out of the chamber when the plates are separated whereupon the cake will be dropped from the filter media into a collection area so that the filter media can be reused.
