Diaphragm filter press filter plate leakage prevention and its application fields
Diaphragm filter press has the advantages of high pressing pressure, good corrosion resistance, convenient maintenance, safety and reliability, etc. It is the best choice for customers in metallurgy, gas, papermaking, coking, pharmaceutical, food, brewing, fine chemical and other industries.
The main difference between the diaphragm filter press and the ordinary box filter press is that two elastic membranes are installed on both sides of the filter plate (the composite rubber diaphragm is an integral diaphragm). The high-pressure fluid medium is injected into the diaphragm plate, and then the entire diaphragm will bulge, pressing the filter cake, so as to achieve further dehydration of the filter cake, that is, pressing filtration.
The filter plate of the diaphragm filter press adopts an intermediate feed separation pipeline, which also has an obvious advantage that the diaphragm filter press can be formed during the filtration process, and the formed filter cake can be evenly formed in the middle of the filter plate. The neatness, the use of the secondary extrusion of the diaphragm filter press. If a half-angle feed separation pipeline is used, it will not only increase the reason for the irregular formation of the filter cake, but also reduce the feed amount, thereby affecting the efficiency of the diaphragm filter press.
The diaphragm filter press realizes a high-efficiency dehydration filtration process, and can ensure that the filter press exerts the best filtering effect and greatly reduces the moisture content of the filter cake. After the feeding process, the dewatering efficiency of the whole machine is improved by pressing the filter cake, the dryness of the filter cake is increased, the pollution and labor are reduced, and the drying process can even be omitted in some processes. If the air blowing operation is added before and after pressing, the moisture content of the filter cake can be further reduced.
