Description

Technical Field

[0001] The utility model relates to a filter element plug-in type cyclone precision filter. Background Art

[0002] Traditional cyclone filters generally enter and exit at a tangent. The liquid is introduced into the filter at a tangent, causing the liquid to swirl in the cylinder, generating a tangential centrifugal force. The impurities in the liquid are thrown to the inner wall of the filter and then fall into the cone bucket at the bottom, achieving separation of solid and liquid impurities.

[0003] The existing method of cleaning the filter residue on the filter screen is to disassemble the filter. The filter screen needs to be disassembled for cleaning, which is troublesome. The filter needs to be disassembled once for each cleaning, and the frequent disassembly takes a long time, which seriously affects the filter production. Therefore, a filter element plug-in cyclone precision filter is proposed to solve the above problems. Utility Model Content
