What is the difference between box type filter press and plate frame filter press

What is the difference between box type filter press and plate frame filter press? Firstly, let's understand what a filter press is? This is a special filtering medium that applies a certain amount of pressure to the object to allow the liquid to seep out. Mechanical equipment is a commonly used solid-liquid separation equipment. The filter plate has stable performance, convenient operation, and is safe and labor-saving; Metal pressure pipes are made of seamless steel pipes and plastic steel filter plates, which are resistant to high temperature, high pressure, and durable. There are two types of box type filter presses, and there are two types of plate and frame filter presses. What is the difference between the two? This is a brief introduction.

1, Structural composition

Plate and frame filter press is a filtration device used for intermittent filtration pressure. It consists of a compression part, a thrust plate, a compression plate, a crossbeam, and a frame. All filter plates and frames are stacked alternately. It is placed on two equal supporting beams. All filter plates and corresponding parts of filter frames have liquid channels for introducing suspension or discharging liquid. All filter plates have the same sealing surfaces on both sides of the filter frame. The filter cloth is sandwiched between the sealing surfaces of the plate and frame, and the sealing gasket is located inside the sealing surface of the filter plate and frame. The filtering surface supporting the filter cloth is covered with grooves, and all grooves and filtrate are discharged. The channel is connected. A filter press consists of multiple parallel filter chambers. Each filter chamber has a filter cloth layer on both sides to prevent the passage of solid particles in the suspension and allow the filtrate to permeate. The total filtration area of the filter plate represents the full production capacity of the filter press.

The plate and frame filter press consists of a filter plate and a filter frame, which can withstand low filtration pressure (usually less than 0.6Mpa). Each filter press has different plate frames according to the size of the area. Filters are usually used for filtering materials with fewer particles. Usually used for filtering fine products. You can use the filter paper on the back of the filter cloth to filter.
