Description

Technical Field

[0002] As an efficient solid-liquid separation equipment, the filter press plays a vital role in the modern ceramic raw material production process. The filter press separates solid particles from liquid by passing the ceramic raw material slurry containing a large amount of water through the filter cloth under high pressure, thereby obtaining a dry filter cake. In the existing filter press technology, after the filtration operation is completed, the separation process of the filter plate usually requires the use of a drag plate device set on the tracks on both sides of the filter press. The device drags the filter plates one by one to separate them from the adjacent filter plates, thereby realizing the disassembly and cleaning of the filter plates.

[0003] Since the plate dragging device can usually only drag one filter plate at a time, and the filter press has multiple filter plates, the plate dragging device needs to drag the filter plates repeatedly, resulting in a long separation process and low efficiency. Utility Model Content
