Working principle of plate and frame filter press

  1、 Brief introduction of plate and frame filter press
The filter press uses the pressure difference on both sides of the filter cloth to force most of the water in the material to flow out of the machine through the filter cloth, and the material is blocked in the filter chamber to form a filter cake to achieve the purpose of filtration
Due to the large pressure difference between the two sides of the filter cloth in the filtration process, the filtration speed is improved and the water content of the filter cake is reduced
The filter cloth is used to make the filtrate pure and clean, and the filtration effect is much better than that of the vacuum filter

Plate and frame filter press is a relatively new and fast filter, which is widely used in the fields of suspension filtration and solid-liquid separation
The plate and frame filter press has the advantages of simple structure, compact equipment, large filtering area and small floor area, high operating pressure, low water content of filter cake and strong applicability to various materials
It is suitable for intermittent operation

  3、 Working principle of plate and frame filter press
  The working principle of plate and frame filter press is relatively simple
Firstly, the filtered material liquid enters into each filter chamber from the feed hole of the rear top plate under pressure through the material transfer pump
Through the filter cloth, the solids are intercepted in the filter chamber and gradually form a filter cake; The liquid is discharged out of the machine through the water outlet hole on the plate frame
With the progress of the filtration process, the filter cake filtration begins, the mud cake thickness increases gradually, and the filtration resistance increases
The longer the filtration time, the higher the separation efficiency
The designed filter cloth can intercept particles smaller than 1μ Particles of M
