The plate and frame filter press is a filter unit composed of a filter plate and a filter frame, which can withstand lower filter pressure. Plate and frame filter press is generally used for filtering materials with less particulate matter, and is often used for filtering precision products. The advantage of the plate and frame filter press is that the filtration quality is high, and the filter cake can be backwashed twice to make the filter cake more pure.

Compared with the box filter press, the filter space is larger and the quantity is faster; it is more convenient and faster to replace the filter cloth, provide the utilization rate, and improve the filter power; the cycle period is long, the filter plate size is the same, and the storage filter cake space is larger, The gap cycle time is longer, which is the main feature of the box filter press; the weight is lighter than the box filter press, which is easy to transport and move. Because of its relatively many advantages, the price is relatively high.

The single filter plate of the box filter press is thicker than the plate and frame filter plate. When compressed, a filter chamber is formed between the two filter plates, which is used to store the granular objects separated by the filter cloth. The feed hole is placed in the center of the filter plate and is generally used for materials with more particulate matter. The characteristic of the chamber filter press is that the bias of each filter chamber should not be formed, so the filter plate should not be damaged. Fast filtering speed, convenient slag unloading, large filtering pressure, low liquid content of filter cake, single active plate unloading, wider customary scale, large filter press can be manufactured.

The advantages of the box-type filter press are low price; stable function, strong wear resistance, and generally one year more than the frame filter press; more and more tidy, which is conducive to the promotion of future intelligence; more useful maintenance filter cloth, Make it longer service life, more convenient for active cleaning; when replacing the filter plate, the standard is the same, no special arrangement is required.
