General filter press filter plate using a diaphragm filter plate and a box filter plate combination, which box filter plate is a solid structure, diaphragm filter plate by the diaphragm and the core plate composition of the internal chamber structure.

The diaphragm filter plate is composed of two diaphragms and a core plate. An external medium (water or compressed air, etc.) is introduced into the chamber between the core plate and the diaphragm, so that the diaphragm swells to compress the diaphragm filter plate and the box The filter cavity composed of the filter plate is compressed, and then better separated and the solid content is improved. Among them, the diaphragm is the main moving part, and repeated movement is easy to cause the diaphragm to deform and damage.

Rubber diaphragm filter plate diaphragm is generally embedded in the core plate groove, easy to remove and replace, because the rubber diaphragm has a high elasticity, so it is not easy to damage.

Polypropylene filter plate diaphragm is generally made of integral welding, the use of welded diaphragm can not be replaced.
