Filter plate of filter press

Abstract

The invention relates to a filter press (1) for filtering suspensions that comprises a plurality of filter plates (1M, 1K) that can be displaced in parallel with respect to one another. In a filtering position, said filter plates can be compressed to a package that comprises a filter chamber (23) between respective two filter plates (1M, 1K), said chamber being provided with at least one filter cloth (7M, 7K). In a discharge position, adjoining filter plates (1M, 1K) can be moved apart by a discharge distance (3) so that the filter cake adhering to the filter cloth (7K) can be discharged. Every filter chamber (3) is correlated with at least one filling element (2) for feeding the suspension to the filter chamber (23). The aim of the invention is to prevent leakages in the zone of the peripheral sealing edge, to guarantee an unimpaired filter capacity during feeding and to facilitate operation of the filter press without an external supply line and outgoing connection lines. To this end, the filling element (2) is disposed on a joining piece (5) that extends outside a plate level and within a sealing edge (27) on the periphery of the filter plates (1M, 1K) and that can be linked with a filter plate (1M). In the filtering position, the filling elements (2) form a suspension supply channel (22) that extends through the filter plate package and are sealingly wedged between adjoining filter plates (1M, 1K).

Description

technical field [0001] The invention relates to a filter plate for a filter press used to filter suspensions, wherein a plurality of filter plates arranged in parallel to each other and relatively movable can be compressed into a filter plate group at the filtering position, and the filter plate group is used for each filter plate group. There is a filter cavity with at least one filter cloth set between the two filter plates, wherein the filter plates can be separated from each other by a slag discharge distance when they are in the slag discharge position, wherein each filter cavity is provided with at least one suspension Feed parts to the filter cavity. Background technique [0002] A filter press with such a filter plate is known from European patent specification EP-0540705 B1. The feed element there is in each case a rod-shaped tubular body which is seated sealingly in an edge-side groove-shaped recess running in the direction of the sealing edge on the edge region. ...

AI Technical Summary

Problems solved by technology

[0007] The disadvantage of corner entry is that the filter cloth must be clamped to the filter plate in the entry area by means of a screw-in clamp

This results in a considerable amount of work when changing the filter cloth
