Two types of filter cloth design for Sudong filter presses improve operational safety and environmental performance


Sudong Chemical Machinery Co., Ltd. is an old brandFilter pressProduction and R&D companies, with rich industry experience, have introduced the following two filter cloths to solve this environmental protection problem in response to the phenomenon that some materials will volatilize toxic and harmful gases when filtering, which will harm the health of operators and pollute the environment.


1. Brush the special rubber slurry on the sealing surface of the filter cloth except the filter surface, thereby blocking the pores in the filter cloth, further increasing the sealing performance of the filter plate, and ensuring the phenomenon of running, leaking, dripping and leakage during the filtering process. The toxic and harmful gases are sealed in the inner cavity of the filter press.


2. Using embedded filter cloth, the filter cloth is embedded in the filter chamber with a rubber ring. A sealing ring is added on the sealing surface of the filter plate to enhance the sealing performance between the filter plates and avoid liquid leakage.

The above two methods solve the problem of filter cloth capillary and sealing surface leakage between the filter plates, avoid the volatilization of toxic and harmful gases, ensure personal safety, and reduce environmental pollution. It should be noted that part of the gas may still volatilize at the end of filtering and unloading. Users with higher requirements need to add a plexiglass cover to the filter press and use an induced draft fan to discharge harmful gases during unloading.
