Description

 Filter press quick unloading cake and cleaning filter cloth device

Technical field

 The present invention relates to the field of filter press manufacturing technology, and more particularly to a filter press quick release cake and a cleaning filter cloth device for use in a filter press.

Background technique

 The filter press is a special filtering device in the solid-liquid separation industry. The filtrate enters the filter press through the feed pump. The filter cloth from the filter media intercepts the particles in the filtrate and forms a filter cake in the filter chamber. The filtrate is discharged from the outlet of the filter plate. Since the filter press can be used in various industries, the characteristics of the filtrate produced in different industries are different. Some filtrates contain not only tiny particles but also strong viscosity, so that highly viscous particles adhere easily. On the filter cloth, the venting hole of the filter cloth is clogged, which causes difficulty in draining, and the filter chamber cannot form a filter cake, thereby seriously affecting the filtering effect of the filter press. In order to solve this problem, the commonly used method is to manually clean the filter cloth with high-pressure water, or to remove the filter cloth from the filter plate for cleaning. The cleaning speed is slow, the labor intensity of the worker is large, and the cleaning water is directly discharged. , it will still cause environmental pollution.

The application number is 200810110557. 5, the invention patent entitled "Crusher cleaning filter cloth device and its preparation method" discloses a filter cloth cleaning device designed to solve the above problems, the cleaning device is supported by a bracket and a mobile vehicle.
