Abstract: A pressure plate filter having a filter vessel with an upper cylindrical section and a lowers downwardly tapering conical section. A stack of spaced-apart filter plates is mounted on a support frame within the filter vessel for pivoting about an offset axis between a lowered filtering position in which the filter plates are horizontally arranged within the conical sections to a raised filter cake discharge position in which the filter plates are supported above the conical section in a sloped position. The stack of filter plates is raised and lowered by means of a hoist assembly. In a further embodiment, the filter includes a separation frame which can move relative to the support frame and which causes the filter plates to move apart relative to each other when placed in the raised discharge position.

Abstract: A vacuum or gas pressure clamp prevents movement of an elongate filter cloth used in a horizontal vacuum filter. The clamp includes a support frame and a planar supporting device having a perforated support surface for supporting the filter cloth. The vacuum clamp is mounted on the frame and is adapted for connection to a vacuum source so that vacuum can be applied to numerous holes in the support surface. An imperforate sealing sheet extends over the support surface and in close proximity thereto. The filter cloth can be drawn between the supporting device and the sealing sheet. A vacuum can be applied to the filter cloth in order to prevent its movement in the longitudinal direction. Preferably the support surface forms a rectangular grid comprising rows of closely spaced holes. This grid is surrounded by a sealing surface. In the gas pressure clamp, an enclosure extends around the supporting device and the sealing sheet and a positive air pressure can be provided in this enclosure. In this version, the perforated support surface can be vented to atmosphere.
