Filter press is a commonly used solid-liquid separation equipment, which is widely used in sludge dewatering projects. It is mainly composed of transmission part, filter plate part, pressing plate part, thrust plate part and pressing device (mainly hydraulic pressure Composed of tightening device), hydraulic system, electronic control system and auxiliary parts.
The filter cloth is installed on both sides of the filter plate. Under the action of the pressing device, the filter plate is pressed between the pressing plate and the thrust plate. A closed filter space is formed between every two filter plates. When the feed pump pumps the material into the closed filter space, under the pressure of the feed, the liquid phase is separated from the liquid filter hole through the filter cloth, and the fixed material stays in the closed filter space to slowly form a filter cake. To realize the solid-liquid separation of the material in pairs, after the feeding pump stops feeding, slowly loosen the compression plate, unload the filter cake, and complete a working cycle.
