Two factors affecting the operating efficiency of filter press

In order to improve the working efficiency of the filter press, we need to have a detailed understanding of many parameters that affect the operation of the equipment. Here, the technical staff of Sudong Chemical will emphasize the two major influencing factors, namely the material concentration and fineness. Especially in the mining and sludge industries, the changes in material concentration and fineness are very unstable, which has a significant impact on the overall work of the filter press.


When the material concentration is very low, the cycle feeding time will be longer. Because the coefficient of the feeding pump is constant, the filter cake will accumulate on the filter cloth for a long time, which will cause a sandwich cake. The state of the filter cake is double-layered. , Can not fall off automatically, this will bring a lot of inconvenience to the unloading work and prolong the cycle time. When the material concentration is too high, the feeding time is shortened, but it needs to be matched with the parameters of the feeding pump, and a stable feeding with a small flow rate and a small pressure is required. The reason is that the material that enters the filter chamber first hangs during the feeding process. On the filter cloth, in the later stage, the material is filtered with the previous material as the filter medium. If the concentration is too high, it will be difficult to filter, so it is necessary to filter slowly and continuously, and give the filter press a certain amount of time to filter.


When the fineness of the material is relatively fine, the situation is very similar to when the material concentration is low. Because the material is very fine, it is easy to block the permeable holes of the filter cloth. It affects the filtering effect, so it needs high pressure and high flow filtering power to help filter. When the material is thicker, it is easier to filter, as long as you master the filtration time, observe the size of the liquid volume and the change of the system pressure.


Summarizing the above content, it can be concluded that suitable and stable material concentration and fineness are the guarantee and basis for the efficient operation of the filter press. Therefore, everyone must control the concentration and fineness of suitable materials by matching the parameters of the feed pump. Ensure and improve the working efficiency of the filter press.
