Suction cleaning device for filter chamber

Abstract

The invention discloses a suction cleaning device for a filter chamber, comprising a sucking disc installation rack (A) and sucking discs (3) arranged on the sucking disc installation rack (A), wherein the sucking disc installation rack (A) comprises two rack rods (1), a part of the sucking disc installation rack (A), which corresponds to each sucking disc (3), is provided with a pair of sucking disc installation seats (11), and a strip-shaped installation hole (11a) is arranged on each sucking disc installation seat (11); a pair of installation lugs are arranged on the outer side of each sucking disc (3), a sucking disc connecting plate (4) is installed on the back face of each sucking disc (3) and is provided with a limit projected column (41), and a spring(5) which enables the sucking discs (3) to tend to all along move away from the sucking disc installation rack(A) is sheathed on the periphery of the limit projected column (41). Compared with the prior art, the contact force between the sucking discs of the invention and filter media can be automatically adjusted by the sucking discs, thereby guaranteeing the effect of cleaning dirt of the filter media, protecting the integrity of the filter media and prolonging the service lives of the filter media.

Description

Suction scrubbers for filters technical field The invention relates to the technical field of filter pools for cooling water and sewage treatment, in particular to a suction and washing device for filter pools that can remove dirt adsorbed on filter media. Background technique At present, suction and washing devices are mostly used in the filter tanks used to treat cooling water and sewage, which are used to absorb dirt adhering to the filter medium in the filter tank, and regularly clean the filter medium to restore it to a workable state. For example, the Chinese utility model patent "Fiber Rotary Disc Filter for Sewage Advanced Filtration Treatment" whose patent number is 200720173409.9 (announcement number is CN201085959Y) discloses a filter cloth back-suction device for the rotary disc filter. The filter cloth reverse suction device is composed of a suction cup, a connecting pipe, an electric valve and a reverse suction water pump. On the side of the disk, there is a...

AI Technical Summary

Problems solved by technology

It can be seen that the suction cup fixing device and the suction cup are fixed relative to the pool body, and the filter disc as the filter medium is constantly rotating around the same axis. When the suction cup encounters the concave surface of the filter disk, the distance between the surface of the filter disk and the suction cup is too large, which cannot ensure that the dirt on the surface of the filter disk can be completely sucked by the suction cup, and the cleaning effect is not ideal. When the suction cup touches the raised surface of the filter disk At this time, the resistance force of the suction cup to the filter disk is too large, the suction cup is easy to scratch the filter disk and appear damaged, the filter tank cannot work normally, and needs to be replaced, which reduces the service life of the filter medium and increases the cost of use.

At the same time, when the dirt on the filter medium is sucked, it is necessary to drive the entire turntable to rotate, which requires high energy consumption and troublesome maintenance
