Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a V-shaped filter with a sand-proof structure. Background Technology

[0002] V-type filters are a type of rapid filter named for the V-shaped shape of their inlet tank. Their main characteristics are uniform water distribution and good backwashing effect. V-type filters are also called uniform granular material filters. V-type filters require backwashing.

[0003] In the actual operation of activated sand filters, if the backwashing intensity is too high, the filter media will be washed away, which is called "sand running phenomenon". Sand running leads to unsatisfactory interception effect, and the need to constantly replenish the filter media will increase economic investment. At the same time, the sand running into the waste liquid tank can enter the volute of the waste liquid pump during operation, causing the pump to operate abnormally and requiring manual labor costs for cleaning. It can also easily block the inlet and outlet. Utility Model Content
