Self-cleaning filter screen

Abstract

The invention discloses a self-cleaning filter screen. The filter screen comprises a filter screen body; a supporting rod is arranged on the lower side wall of the filter screen body; the filter screen body is rotationally connected with the upper end of the supporting rod; the lower end of the supporting rod is fixedly connected with a telescopic spring; a rotary disc is arranged on the outer side of the supporting rod; a gear making contact with the outer wall of the supporting rod is rotationally connected to the inner wall of the rotary disc; saw teeth meshed with the gear are arranged onthe outer wall of the supporting rod; an abutting rod is rotationally connected to the outer wall of the rotary disc; a transverse plate is arranged on the upper side wall of the filter screen body; awater tank is rotationally connected to the end of the transverse plate; the end of the abutting rod makes contact with the outer wall of the water tank; and a fixing plate is arranged on the lower side of the filter screen body. The filter screen body moves downwards to drive the rotary disc to rotate due to excessive impurities, the abutting rod moves, then the water tank is driven to incline automatically, water is poured out to flush the filter screen body, self-cleaning of the filter screen body is achieved, and the filtering effect of the filter screen body is guaranteed.

Description

technical field [0001] The invention relates to the technical field of municipal facilities, in particular to a self-cleaning filter screen. Background technique [0002] The filter screen is a component used for water filtration in municipal administration, and it is used to filter impurities in the water body to facilitate the subsequent water purification process. [0003] The filter is generally set on the lower side of the drain to filter impurities. This filter can prevent some large particles of solids from entering the drain and causing blockage of the drain. However, as the filter filters more and more filtrates, the impurities on the surface will gradually Accumulation, thereby affecting the water filtration effect of the filter screen. Contents of the invention [0004] The object of the present invention is to propose a self-cleaning filter screen in order to solve the problems in the background technology. [0005] In order to achieve the above object, the p...
