Blowback and stripping system of filter press

The filter press designed and produced by Sudong Chemical is equipped with a backflush and blow-off system, which consists of an air compression system and a compressed air storage system and management. After being compressed by a screw air compressor, the air enters the air storage tank for storage, and the stored air is connected to the filter press itself through a pipeline.

It is divided into two links: filter press-diaphragm filter press-plate and frame filter press-Jiangsu Sudong Chemical Machinery Co., Ltd. Backflush is to use high-pressure air to blow air from the central feed pipe at the tail end of the filter press, so that the unfiltered sludge with high water content in the central feed pipe passes through the high-pressure air thrust so that the unfiltered sludge is placed in the aggregate pool through the return pipe, preventing the central pipeline from having high water content mud flowing out when unloading.

The blow-off air is blown off from the filtrate pipe on the front end of the filter press, so that the high-pressure air penetrates the filter cloth from one side of the filter plate and blows out the surface water of the mud cake and the filter cloth, making it easier to unload the mud when the filter cloth and the mud cake are separated. The blow-off air pressure is 0.7-0.8Mpa, and the backflush and blow-off time and number can be adjusted.

The XMYZF150-1250 reinforced polypropylene chamber filter press ordered by the customer is used for kitchen wastewater treatment.
