A self-cleaning filter

Abstract

The invention discloses a self-cleaning filter screen, comprising a filter screen body, the lower side wall of the filter screen body is provided with a support rod, the filter screen body is rotatably connected to the upper end of the support rod, and the lower end of the support rod is fixed A telescopic spring is connected, and a turntable is arranged on the outside of the pole. The inner wall of the turntable is rotatably connected with a gear in contact with the outer wall of the pole. The outer wall of the pole is provided with sawtooth meshing with the gear. The outer wall of the turntable is rotatably connected with a resisting rod, the upper side wall of the filter body is provided with a horizontal plate, the end of the horizontal plate is rotatably connected with a water tank, and the end of the resisting rod is in contact with the outer wall of the water tank , the lower side of the filter body is provided with a fixing plate. In the present invention, when there are too many impurities on the filter screen body, it moves down to drive the turntable to rotate to realize the movement of the lever, and then drives the water tank to automatically tilt to make the water pour out to wash the filter screen body, so as to realize the self-cleaning of the filter screen body and ensure the filter screen Ontology filtering effect.

Description

Technical field [0001] The present invention relates to the technical field of municipal facilities, particularly to a self-cleaning filter. Background technique [0002] Screen is a component for municipal water was filtered, the filter for water purification of the impurities to facilitate the subsequent process water. [0003] Screen typically provided on the lower side of the discharge port to filter impurities, the filter can prevent some solid particles into the drain caused by the large drain plug, but with the filter the filter more filtrate, which surface impurities will gradually accumulation, thereby affecting the drainage of the filter effect. Inventive content [0004] Object of the present invention is to solve the problems in the background art, a method proposed self-cleaning filter. [0005] In order to achieve the above object, the present invention adopts the following technical solution: [0006] A self-cleaning filter, comprising a filter body, the side wall...

AI Technical Summary

Problems solved by technology

[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 surface impurities will gradually Accumulation, thereby affecting the water filtration effect of the filter
