The influence of filter plate design on the performance of plate and frame filter press

Familiar withPlate and frame filter pressAll of our customers know that the filter plate is one of the very important components of the plate and frame filter press. It can be said that the quality of the filter plate directly affects the performance of the plate and frame filter press. The quality of the filter plate depends on the material, quality and design of the filter plate. Today Su Dong will focus on the impact of the filter plate design on the performance of the plate and frame filter press.


In fact, the structure of the filter plate of the plate and frame filter press is relatively simple. The hollow in the middle is the same as the splicing of four filter plates. The hollow part in the middle is used to allow the filter cloth to contact the filter liquid. The area of ​​the hollow part is Larger, the larger the contact area between the filter cloth and the filtrate, the greater the filter efficiency of the corresponding plate and frame filter press. The remaining volume between the area and the thickness of the filter plate is used to store the filtered material that was blocked during filtration. Similarly, the larger the volume, the greater the capacity of the solids that can be stored, and the stronger the capacity of the corresponding plate and frame filter press for the same gap cycle processing.


Therefore, when designing the filter plate, it is necessary to reserve the area of ​​the filter cloth as much as possible, but the premise is to ensure the strong pressure of the plate frame, that is, the pressure of the solid against the filter plate. Therefore, in order to ensure the pressure, increase The area of ​​the filter cloth should make the filter plate stronger. Under normal circumstances, the edge width of the filter plate is often designed to be between 80mm and 120mm.


The above content is the influence of the design of the filter plate on the performance of the plate and frame filter press. Therefore, in order to achieve the best performance of the plate and frame filter press, when designing the filter plate, it is necessary to coordinate the pressure of the filter press and the filter cloth area. Don’t lose sight of the relationship between one another.
