Problems solved by technology

Existing filters all use filter elements to filter the water body. If the filter elements are used for a long time, the accumulation of sundries on the filter elements will easily affect the water quality. In severe cases, the filter will be clogged and invalid. , and the cost of maintenance by professionals is high

Abstract

The invention relates to a self-cleaning mechanical filter, which comprises a filter element and a barrel. The filter element is arranged in a filtering cavity of the barrel, a water inlet cavity with a water inlet is arranged at the bottom of the barrel, a water outlet is arranged on a side wall of the barrel, the water inlet is communicated to the water outlet via the water inlet cavity, the filter element and the filtering cavity respectively, a backwashing elbow is disposed in the water inlet cavity, the backwash elbow can be rotationally communicated with the filter element or the water inlet cavity can be rotationally communicated with the filter element via the backwashing elbow, and the backwashing elbow is connected with a backwashing outlet outside the water inlet cavity. The backwashing elbow rotates, so that the filter element is respectively communicated with the water inlet cavity and the backwashing elbow, and a normal filtering function and a filter element self-cleaning function of the filter are respectively realized. The self-cleaning mechanical filter is simple and compact in structure and convenient in use, does not need manual maintenance and saves cost. The filter element can be cleaned automatically.

Description

technical field [0001] The invention relates to a filter device, in particular to a mechanical filter with self-cleaning function. Background technique [0002] As a widely used device for water purification, the filter can filter out the sundries in the water to ensure the water quality. Existing filters all use filter elements to filter the water body. If the filter elements are used for a long time, the accumulation of sundries on the filter elements will easily affect the water quality. In severe cases, the filters will be blocked and fail. , and the cost of maintenance by professionals is high. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a self-cleaning mechanical filter with simple and compact structure, which can automatically clean the filter element, is convenient to use, requires no maintenance, and saves costs. [0004] The technical solution adopted in the present inv...
