How to prevent filter cloth clogging of plate and frame filter press

The working operation of the plate and frame filter press is to first press the plate and frame group by hydraulic pressure, and the sedimented sludge enters from the middle and is distributed between the filter cloths. The solid and liquid separation is achieved through the filtering medium. It can be seen that filter cloth plays a key role in the plate and frame filter press. If the filter cloth is blocked, the normal operation of the plate and frame filter press will be affected. Next, Sudong Chemical will introduce several methods to prevent the filter cloth of the plate and frame filter press from clogging.


1. The material used in the filter cloth of the plate and frame filter press, the size of the filter hole, and the interface technology will all affect the filtering effect of the filter cloth, and also cause the filter cloth to block.


2. Using polyester material, this material is generally suitable for acid filters, but also high temperature resistance, strong tensile strength, vertical and horizontal stability, abrasion resistance second only to nylon, and this is currently the most widely used filter on the market Cloth material.


3. The filter cloth is made of polypropylene. This material has better acid and alkali resistance. It is generally used at a temperature below 90 degrees. The disadvantage is that the tensile strength is not high. Under normal circumstances, most companies will not choose it, but there are some special industries will choose, this product is higher in alkali resistance.


The plate and frame filter press has good sealing performance, high filtration pressure, and strong adaptability to slurry, and it has been widely used at present. The clogging of the filter cloth seriously affects the working efficiency and filtering effect of the plate and frame filter press. Therefore, when we usually use the plate and frame filter press, we must pay attention to selecting the appropriate filter cloth, and regularly check and maintain the filter cloth.
