The structure and operation regulations of high pressure diaphragm filter press are introduced in detail.

1、 Greatly reduce the moisture content of filter cake and complete the reduction of filter cake.

2、 Protect the ecological environment, reduce energy consumption and filter cycle time.

3、 Increase the service life of the diaphragm filter press.

With the increase of the working pressure of filtration, the risk of gas pressure will also increase rapidly at the end of each filtration cycle. According to diaphragm technology, low-voltage filtration and high-pressure extrusion greatly prevent the generation of gas pressure, and the gas pressure is just the primary cause of filter plate damage.

Principle of high-pressure diaphragm filter press: with the help of the transfer pump, the filter cloth in the filter room, a major advantage of the high-pressure diaphragm filter press is that it can carry out the special design scheme of the second dry extrusion filtration birthday cake filter room, so that the filter room can automatically close the supply valve after it is filled with filtered birthday cake, and make the filter cloth swell and deform according to the vapor or liquid, so as to achieve the effect of secondary extraction of the filter cake and further reduce the water content.

The structure of high pressure diaphragm filter press consists of three parts.

1. Sound card frame: the frame is the basic component of the high-pressure diaphragm filter press. The two sides are the driving plate and the pulling force. The two sides are connected by the car beam. The car beam is used to support the filter plate, filter frame and pin of the point filter press.

2. The filter tissue system consists of filter plate, filter framework, filter cloth and squeeze diaphragm. Both sides of the filter plate are covered by filter cloth. When squeeze diaphragm is required, the filter plate group consists of diaphragm and back plate.

Both sides of the bottom plate of the high pressure diaphragm filter press are covered with plastic diaphragms, and both sides of the diaphragm are covered with filter cloth. The baffle plate is the filter plate of general filter press. Raw materials enter each filter chamber from the time-lapse material hole on the thrust plate, the solid particles are intercepted in the filter chamber because their particle diameter exceeds the diameter of the filter material (filter cloth), and the leachate is discharged from the drain hole under the filter plate. When the filter cake needs to be squeezed dry, in addition to the diaphragm, air compression or steam can be introduced from the cleaning port to wash away the water in the filter cake according to the cyclone, so as to reduce the water content of the filter cake.
