Abstract

The invention provides a membrane filter plate. The membrane filter plate comprises a solid core plate and two membranes respectively arranged on two sides of the solid core plate, wherein an internal cavity is formed between each membrane and the solid core plate; the solid core plate comprises a middle plate body and a plate frame surrounding the middle plate body; edge positions of the middle plate body and the membranes are connected, and first grooves are formed at the joints of the middle plate body and the membranes; the first grooves are located on the surfaces of one sides, back on to the solid core plate, on the membranes. According to the membrane filter plate, the deformation stresses borne by the membranes due to the expansion of the membranes in a use process can be reduced, and the deformation of the membranes caused due to the deformation stresses can be relieved; meanwhile, the flow-out speed of filter liquid as well as the flow-in speed of washing liquid can be increased.

Description

technical field [0001] The invention relates to the field of filter press components, in particular to a diaphragm filter plate. Background technique [0002] Generally, the filter plate of the filter press is used in combination with a diaphragm filter plate and a box-type filter plate at intervals. The box-type filter plate is a solid structure, and the diaphragm filter plate consists of two diaphragms and a core plate to form an internal chamber structure. When in use, an external medium (water or compressed air, etc.) is introduced into the chamber between the core plate and the diaphragm to make the diaphragm bulge to compress the filter chamber composed of the diaphragm filter plate and the box filter plate, thereby better Separation of liquid and solid, increase the solid content. [0003] The purpose of the diaphragm filter plate is to increase the dehydration efficiency of the filter press, increase the dryness of the filter cake, reduce pollution and reduce labor ...
