PLATES AND FRAMES FOR FILTER PRESSES WITH A HIGH DEHYDRATING CAPACITY ACHIEVED BY VOLUME VARIATIONS AND A FILTER PRESS MADE WITH SAID PLATES AND/OR SAID FRAMES

摘要

To achieve a better dehydration of the slurry collected in the filtering chambers of a filter press, the filter pack is be compressed at the end of the filtering process, by bringing the plates (5a) in the filter pack (5) closer together and consequently reducing the volume of the filtering chambers. Said volume reduction is obtained, for instance, by elastically deforming the edges (5f) of the interconnected plates forming the filter pack (5).
