Diaphragm frame filter press, also known as diaphragm filter press, is an upgraded equipment of box filter press. The diaphragm filter press has a good effect on the processing capacity per unit area, reducing the moisture content of the filter cake, and adapting to material properties, making solid-liquid separation more thorough.
The difference between a diaphragm filter press and a plate and frame filter press is that there is an elastic diaphragm filter plate sandwiched between two filter plates and the filter cloth. After the feeding is completed, high-pressure fluid or gas medium is injected into the diaphragm filter plate, and then the diaphragm filter plate will bulge and squeeze the filter cake on both sides. The secondary pressing of the filter cake can achieve the effect of deep dehydration of the filter cake. Compared with ordinary filter presses, diaphragm filter presses also have higher solid content in the filter cake.
Diaphragm filter press is widely used in various fields that require solid-liquid separation, such as urban sludge dewatering, chemical industry, metallurgy, petroleum, food, medicine, brewing, papermaking, steel, coking, etc. Diaphragm filter press has the advantages of corrosion resistance, high pressure, and simple and convenient maintenance.
The filter cake processed by the diaphragm filter press has the advantages of high solid content and low moisture content. Greatly reducing the transportation and post-processing costs of filter cake. The filter cake can also be directly burned in the power plant, truly converting sludge into resources and sewage into clean water.
