What is the difference between a plate and frame filter press and a chamber filter press?

Since there are always people who can't tell the difference between plate and frame filter press and chamber filter press, let's briefly analyze them today~
The plate and frame filter press consists of alternately arranged filter plates and filter frames. The board and frame are supported on the beams by means of handles on both sides. There are grooves on the surface of the filter plate to support and cover the filter cloth. The pressing plate moves, the thrust plate fixes the pressing plate and frame, and a filter chamber is formed between the plate and frame. There are through holes in the corners of the filter plate and filter frame, which form a complete channel after assembly. The pressurized material can enter the filter chamber through this channel. After the filtrate passes through the filter cloth, it is discharged through the channels on the surface of the filter plate. After filtration, the filter residue can be washed with clean water. After washing, the remaining washing liquid is sometimes removed by compressed air. Then open the compression plate, remove the filter residue, clean the filter cloth, and re-press the plate and frame, and so on. The single filter plate of the chamber filter press is thicker than the plate and frame filter plate, that is, the chamber filter press consists of two identical filter plates. When the two filter plates are compressed, a filter chamber is formed to store the granular objects isolated by the filter cloth. The feed hole is placed in the center of the filter plate. It is generally used in industries with large amounts of granular materials such as sewage treatment, mineral processing, and coal washing. The chamber filter press should not cause bias pressure in each filter chamber, so the filter plate should not be damaged. It has fast filtration speed, convenient slag discharge, high filtration pressure, low liquid content in the filter cake, and can withstand the maximum filtration pressure of up to 3.0Mpa. It is easy to Realize automatic plate unloading and wider adaptability. The main differences between plate and frame filter press and chamber filter press are the filter plate, feeding method and discharge method. The filter chamber of the plate and frame filter press is composed of filter plates and filter frames arranged in sequence, and adopts the form of angle feeding. The filter chamber of the chamber filter press is directly composed of filter plates and adopts the form of intermediate feeding. In addition, the plate and frame filter press can only discharge materials through manual pull plates, while the chamber filter press can use manual pull plate discharge and automatic pull plate discharge. The chamber filter press is an upgrade of the plate and frame filter press. It is better than the plate and frame filter press in terms of filtration effect and degree of automation.
