The diaphragm filter press is generally considered to be an upgraded version of the ordinary box filter press. Compared with the ordinary box filter press, the diaphragm filter press realizes the further dewatering of the filter cake and reduces the transportation cost of the filter cake. Now it's metallurgy. Papermaking. Medicine. Widely used in food and other industries. The advantages of the diaphragm filter press are described in detail below.

1. The use of low-pressure filtration and high-pressure squeezing can greatly shorten the entire filtration cycle.

2. Using TPE elastomer, the filtration pressure can reach 25MPA, which greatly reduces the water content, saves the drying cost and increases the output.

3. Save operation power consumption, small flow after filtration and high pressure.

4. The diaphragm pressing function completes this process in a very short time, saving power consumption.

5. Increase the degree of mud cake, reduce the content of mud cake. The filter cake after the second extrusion of the diaphragm rearranges the filter cake structure, increases the density, replaces part of the water, and improves the dryness.

6. Strong corrosion resistance, basically suitable for all solid-liquid separation operations.

7. Configurable PLC man-machine interface control.

8. The diaphragm filter plate has fatigue resistance. Anti-aging. Sealing performance.

The main difference between the diaphragm filter press and the ordinary box filter press is that there are two elastic membranes on both sides of the diaphragm. During operation, a high pressure fluid medium may be injected into the diaphragm. When the filter cake fills the entire filter chamber, the device stops filtering, and then fills the filter plate with an expanding material (such as water or air). At this point, the entire membrane will expand and exert pressure on the filter cake. With the increase of pressure, the filter cake can be pressed out through the liquid of the filter cloth, so as to realize the secondary dehydration of the filter cake and reduce the water content of the filter cake.
