Diaphragm filter press, that is, diaphragm filter press, is a filter press with a layer of elastic film added between the filter plate and the filter cloth. During use, when the feeding is finished, the high-pressure fluid or gas medium can be injected into the diaphragm plate, then the whole diaphragm will bulge and press the filter cake, thus realizing the further dehydration of the filter cake, which is commonly referred to as pressing and filtering.

Diaphragm filter press has the advantages of high pressing pressure, good corrosion resistance, convenient maintenance, safety and reliability. It is metallurgy, gas, papermaking, coking, pharmaceutical, food, brewing, fine chemical industry and other industries.

diaphragm filter press has been widely used in various fields requiring solid-liquid separation. The diaphragm filter press is considered as an alternative upgrade equipment to the common chamber filter press.

Diaphragm filter press in the unit area processing capacity, reduce the filter cake moisture, the processing material properties of adaptability, etc. have shown good results.

Diaphragm filter press and ordinary box type filter press the main difference is in the filter plate on both sides of the installation of two pieces of elastic membrane, the operation process, when the end of the feed, the high pressure fluid medium into the diaphragm plate, then the whole diaphragm will bulge, oppression filter cake, so as to achieve the filter cake further dehydration, is the press filter.
