A flat cross-flow security filter device

Abstract

The invention discloses a flat plate cross-flow security filter device, which belongs to the technical field of water treatment and includes a water inlet barrel, a water tank and a water pump, and also includes a filter assembly, a water inlet pipe, a water inlet branch pipe, a water outlet pipe, and a water outlet branch pipe. The water bucket is arranged on one side of the water tank, and several filter assemblies are provided, and several of the filter assemblies are arranged in the water tank, and the quantity of the water inlet branch pipe and the water outlet branch pipe corresponds to the number of the filter assemblies, and the water inlet branch pipe is provided with On one side of the filter assembly, the outlet branch pipe is arranged on the other side of the filter assembly. When the present invention works, the water pump transfers the sewage in the water inlet bucket to the water inlet pipe, and the sewage is dispersed to each water inlet branch pipe through the water inlet pipe and then enters the filter assembly, and the filter assembly absorbs impurities in the sewage, and finally passes through each water outlet branch pipe It enters the outlet pipe and is discharged. In the present invention, the inlet and outlet water adopts a cross-flow design, which is not easy to form blockage, has a long service time, and reduces the frequency of daily membrane replacement.

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...
