Sewage filtering device with buffer mechanism

Abstract

A sewage filtering device with a buffer mechanism is disclosed in the invention, and comprises a working box and a compression mechanism, a center shaft is vertically and rotatably connected in the working box, the center shaft is slidably sleeved with a buffer plate, two sliding holes are symmetrically formed in the two sides of the working box, a flat plate is fixedly connected to the inner wall of the bottom of each sliding hole, a supporting rod is fixedly connected to the upper end face of each flat plate, a gear is rotationally connected to the upper end of each supporting rod, two toothed plates are connected to the two sides of each gear in a meshed mode, each toothed plate is slidably connected to the inner wall of the corresponding sliding hole, and the other ends, close to one side of the center shaft, of the toothed plates are fixedly connected to the buffer plate. Through the cooperation of the buffer plate, the toothed plate and the spring, the situation that sewage directly impacts the filter screen to deform or damage the filter screen can be prevented, then the filter screen is protected, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of filtering, in particular to a sewage filtering device with a buffer mechanism. Background technique [0002] With the acceleration of urbanization, the discharge of urban sewage has increased rapidly. The serious situation of water pollution is becoming an important factor restricting development. Sewage treatment is an important link in the treatment of water pollution. In the process of sewage treatment, filtering sewage is an indispensable process. [0003] At present, most of the sewage treatment devices use filters to filter the sewage, but the sewage directly rushes through the filter, and the water flow will generate a large impact force, which will deform or damage the filter, which will lead to the failure of the filter. Reduced service life. [0004] In view of the above problems, we propose a sewage filtering device with a buffer mechanism. Contents of the invention [0005] The purpose o...
