The structure combination of the filter plate of the diaphragm press filter

The filter plate of the diaphragm filter press adopts a combination of a diaphragm filter plate and a box filter plate, in which the box filter plate is a solid structure, and the diaphragm filter plate is composed of a diaphragm and a core plate to form the internal chamber structure. 


The diaphragm filter plate is composed of two diaphragms and a core plate, which flows into the external medium (water or compressed air, etc.) into the chamber between the core plate and the diaphragm, so as to make the diaphragm bulge and compress the filter cavity composed of the diaphragm filter plate and the box filter plate. and then better separation, improve solid content.Among them, the diaphragm is the main moving part, and repeated movement can easily cause the diaphragm to deform and then damage. 


The diaphragm filter plate is divided into rubber diaphragm filter plate and polypropylene diaphragm filter plate. The rubber diaphragm filter plate diaphragm is generally embedded in the groove of the core plate, which is easy to disassemble and replace, because the rubber diaphragm has high elasticity, so it is not easy to damage. Polypropylene filter plate diaphragm is generally made by integral welding, and the welded diaphragm can not be replaced.
