Annular combined backwashing water filter

Abstract

The invention discloses an annular combined backwashing water filter, which relates to the technical field of environmental protection equipment, and comprises a telescopic transposition mechanism, awater filtering unit, a lifting top cover mechanism and a lifting sewage disc mechanism. According to the design scheme, the four groups of water filtering units which are uniformly distributed in theannular array are driven by pressure provided by the telescopic transposition mechanism to realize sealing, mutual connection, combination and assembly; the upper end surface and the lower end surface of a water filtering shell are effectively connected in a sealing manner under the symmetrical extrusion of the bottom lifting sewage disc and the top lifting top cover mechainism; on the premise that normal use of the water filtering unit is guaranteed, all components of the water filtering unit are automatically disassembled and assembled in a butt joint mode, the cleaning convenience of the water filtering unit is greatly improved, the cleaning efficiency and the cleaning thoroughness are improved, the water filtering quality can be guaranteed, the water filtering efficiency is improved,and the service life of the water filter is prolonged.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to an annular combined backwash water filter. Background technique [0002] At present, backwash water filters are widely used as environmental protection equipment for sewage treatment, but at present, after long-term use of backwash water filters, it is easy to cause the filter tank shell and filter screen to be adhered to scale and tiny impurities, resulting in filter tubes The quality of water filtration is reduced, the efficiency of water filtration is reduced, and the service life of the water filter is reduced. At present, the cleaning of the internal components of the backwash water filter requires the overall disassembly of the water filter to be reassembled after cleaning. low efficiency. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the present invention provides an annular combined back...
