Box-type filter plates are used for solid-liquid separation occupations such as petroleum, chemical industry, metallurgy, coal and medicine, light industrial food, environmental protection textile, clay, etc. The sealing performance of the filter plate should be kept clean and tidy. When pressing, the filter cloth should be checked to ensure that it is not folded, damaged and slag-free, so as to make it flat and defect-free, so as to ensure the filtering effect. The filter cloth should be washed together to ensure the filtering performance of the filter cloth, the filter plate should be cleaned and neatly arranged on the frame of the box filter press, and pressed with a pressure of 1-5 MPa. The box filter plate can be replaced with different filter cloths according to the different filtered solutions, and the number of filter plate layers can be appropriately reduced or added according to the user's production flow rate to be very fine, so as to make it suitable for production requirements. The depression of the box filter plate and the outstanding particle depression at the bottom make room for the filtered filter cake, the filter cake is collected and stored in such a space. The small particles at the bottom are for the friction force between the filter cloth and filter cake of the filter plate in the filtration, and play a useful support for the filter cake when the filter cake accumulates too much. There are also several relatively large bosses at the bottom of the filter plate. The height of the bosses is consistent with the height of the filter plate edge. In the filtration process, there is a boss in the pressure environment, and the middle of the filter plate can transmit pressure, make the pressure uniform and better protect and support the filter plate, avoid; filter plate local force, can not bear and damage.

The box filter plate is of solid structure. Two adjacent depressed filter plates are placed to form a filter chamber. The two sides of the filter plate are recessed. Every two filter plates are combined to form a box filter chamber. The surface of the filter plate is grooved. The outstanding part of the filter plate is fixed on each filter plate with supported filter cloth. The main advantages are less loss during feeding, fast filtering speed, good sealing performance, uniform filter cake washing and low water content, and the pressure of each filter chamber is not easy to damage the plate. High degree of automation, cleaning filter cloth also has automatic device, filter cloth is easy to replace. Wide scope of application.
