A Preliminary Filter for Photochemical Sewage Treatment

Abstract

The invention discloses a primary filter for photochemical sewage treatment, which comprises a filter housing, a motor, a first bevel gear, a second bevel gear and a spring, and a motor is fixedly installed inside the filter housing. And the lower end of the motor is fixedly equipped with a first bevel gear, the right end of the first bevel gear is engaged with the second bevel gear, and the inside of the second bevel gear is welded with a first connecting shaft. The left end of a connection shaft passes through the connection block and is connected to the inner wall of the filter housing, and the front end surface of the connection block is welded with a first protrusion, and the first protrusion and the second protrusion are connected to each other. In the preliminary filter for photochemical sewage treatment, when the connecting block rotates, the connecting rod slides upward through the first bump and the second bump, and the side of the connecting block is regarded as a fan shape, so that the connecting block can be rotated about 180°. Effectively drive the connecting rod to slide down, so that the connecting rod can slide up and down intermittently.

Description

technical field [0001] The invention relates to the technical field of photochemical sewage treatment, in particular to a primary filter for photochemical sewage treatment. Background technique [0002] Photochemical sewage treatment refers to the treatment of sewage through technologies such as biotechnology, photosynthesis, energy transfer, trace elements, water and electronics, and low-energy organic matter. In order to save the cost of photochemical sewage treatment, it is necessary to conduct preliminary treatment of sewage Filtration, the preliminary filter can effectively filter some impurities that are relatively easy to separate first, so that only some impurities that are difficult to decompose will be treated in the subsequent photochemical sewage treatment, so as to achieve the effect of reducing costs, but the existing photochemical sewage The primary filter for processing generally has the following problems when used; [0003] 1. It is inconvenient to filter ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a preliminary filter for photochemical sewage treatment, to solve the inconvenience proposed by the above-mentioned background technology to filter the filter plate to a certain extent, so that the filter plate is prone to clogging when filtering, resulting in filter The filtering work cannot be carried out effectively, which in turn affects the working efficiency of the overall photochemical sewage treatment. After the preliminary filtering work is completed, when cleaning the internally filtered impurities, the operation is not convenient enough, which affects the subsequent preliminary filtering again. problem of work efficiency
