The plate and frame filter press
By using the structural design of the plate and frame filter press, an effective pressure difference environment is formed for both sides of the medium, and the medium can only allow liquid to permeate through, and can intercept the solid interception to the medium, thus realizing the frame pressure. The basic principle of filter separation of the filter. All in all, they all use the barrier separation of the plate and frame filter press media to achieve the essence of solid-liquid separation.
The reason for the different categories is that they handle the filtering details differently. To illustrate this point we have to explain the difference in the filtering structure between them. Each plate filter press has the same chance, and the top of the filter plate is recessed to form a space for storing the filter cake, and the two sides are respectively put on the filter cloth and connected in the middle. The combination of the filter plate and the filter cloth is squeezed and connected to a plurality of filter plates and filter cloths of the same structure, so that the same filter cloth space as the hoist string is formed, which is the chamber filter press filter chamber.
The plate and frame filter presses are different. The filter plates of the plate and frame filter press can be divided into two types, a solid filter plate and a plate and frame filter plate. There is a feed channel at the corner of the filter plate to divert the filtrate to the filter chamber. Among them, the two solid filter plates are sandwiched between the hollow plate frames, and the filter frame is placed on the plate frame, thus forming the filter structure of the plate and frame filter press. This is also the origin of the name of the plate and frame filter press.
