Problems solved by technology

[0002] The main key technology of liquid filtration lies in the discharge of impurities. At present, the shunt design or backwash design is mainly adopted. Two technical schemes are adopted: shunt flushing and backwashing. Shunt flushing is easy to realize automation, but the flushing is not thorough, and impurities are embedded in the filter mesh. Blockage is formed, and backwashing requires multiple valves to control, and the failure rate is high

Description

technical field [0001] The split-flow filtering device with backwashing provided by the invention relates to a split-flow liquid filtering device with backwashing function. It is suitable for the field of liquid filtration, especially the filtration of water, oil and other liquids. Background technique [0002] The main key technology of liquid filtration lies in the discharge of impurities. At present, the shunt design or backwash design is mainly adopted. Two technical schemes are adopted: shunt flushing and backwashing. Shunt flushing is easy to realize automation, but the flushing is not thorough, and impurities are embedded in the filter mesh. Blockage is formed, and backwashing requires multiple valves to control, and the failure rate is high. Contents of the invention [0003] The object of the present invention is to provide a shunt type filter device with backwashing to filter the impurities in the liquid, and combine the two methods of forward flushing and backw...
