Flat cross-flow security filter device

Abstract

The invention discloses a flat cross-flow security filter device, and belongs to the technical field of water treatment. The device comprises a water inlet bucket, a water tank and a water pump, and also comprises a plurality of filter assemblies, a water inlet pipe, water inlet branch pipes, a water outlet pipe and water outlet branch pipes, the water inlet bucket is arranged on one side of the water tank, the plurality of filter assemblies are arranged in the water tank, the number of the water inlet branch pipes and the number of the water outlet branch pipes correspond to the number of the filtering assemblies, the water inlet branch pipes are arranged on one sides of the filter assemblies, and the water outlet branch pipes are arranged on the other sides of the filter assemblies. When the flat cross-flow security filter device works, sewage in the water inlet bucket is conveyed into the water inlet pipe through the water pump, the sewage is dispersed into the water inlet branch pipes through the water inlet pipe and then enters the filter assemblies, the filter assemblies adsorb impurities in the sewage, and finally the sewage enters the water outlet pipe through the water outlet branch pipes to be discharged. The service time is long, and the daily film changing frequency is reduced.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a flat cross-flow security filter. Background technique [0002] In my country's metallurgical chemical industry, pharmaceutical processing, food processing and scientific experiments and other industries, the pre-treatment of waste liquid needs to filter out impurities such as sediment and microorganisms in a large amount of water, aqueous solution or other liquids. For the filtration of a large amount of liquid, the common method is to filter the liquid through a microporous filter membrane of appropriate pore size. [0003] However, some waste liquids are directly fed into the membrane or processed by high-precision equipment, which will adhere to the membrane due to its certain viscosity and affect the efficiency of the filtration membrane. It needs to be removed during pretreatment; the general microporous filter on the market It is easy to block and difficult to cl...
