Chemistry Industry Sulphate/Hydrometallurgy Filter Press

Chemistry Industry Sulphate/Hydrometallurgy Filter Press

The filtering press consists of filter plate, filter frame, filter cloth and squeezing diaphragm. The two sides of the filter plate is coated by cloth. When squeezing diaphragm need to configure, filter plate consists of diaphragm plate and side plate.Chamber filter press is the primary and intermittent filter equipment. It is used in solid-liquid (solid content is better of 5%-50%) separation of varipis suspension. widely used in mining, chemical. metallurgy, medicine, textile, food, inorhanic salt and other industries.This filter press consists of beam, filter plate, hydraulic unit. and control cabinet.

Filter Press Working Flow:

1- Closing of the press: as the filter is completely empty, the moving head activated by the jacks calmps the plates. 

2- Filling: For sludge having good filter ability it is best to fill the filter very quickly so as to avoid the formation of a cake in the first chamber before the last ones have been filled.

3- Filtration:  When the filtration pump has stopped, the filtrate circuits and central duct, which is still filled with liquid sludge, are purged by compressed air.

4- Filter opening: The moving head is drawn back to disengage the first filtration chamber. The cake falls has a result of his own weight. A mechanised system pulls out the plates one by one. 

5- Washing: Washing of clothes should be carried out every 15-30 processing oprations. For mid- or large units this take place on press using water sprayers at very high pressure (80-100 bar).
