Abstract

The invention discloses a grid for sewage treatment. The grid comprises a main plate, wherein a coarse grid and a fine grid are arranged on the side wall of one side of the main plate and are parallel; the fine grid is fixedly connected with the side wall of one side of the main plate, and the coarse grid is connected with the side wall of one side of the main plate in a sliding manner; a supporting rod is also vertically arranged on the main plate, and is positioned between the coarse grid and the fine grid; a first supporting plate is also horizontally arranged between the coarse grid and the fine grid, and the side wall of one side of the first supporting plate is fixedly connected with the supporting rod; the supporting plate is also provided with a slag discharging pipe vertically arranged, and the slag discharging pipe is positioned between the supporting rod and the fine grid; the main plate is provided with two driving motors which are symmetrically arranged, and the two driving motors are respectively arranged at the two sides of the supporting rod; the tail ends of outputs shafts of the two driving motors are respectively connected with a gear. The grid for sewage treatment disclosed by the invention has the beneficial effects that floating substances on the water can be conveniently cleared, no influence on filtration of the grids is caused and the sewage treating efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a grid for sewage treatment. Background technique [0002] Grille, also known as steel grating, steel grating, or grating plate, is a tool device welded by flat steel and twisted steel. It is mainly used in construction, design and decoration, sewage treatment, engineering applications and other fields. The grills are mainly divided into three types: coarse grills, medium grills and fine grills. There are three types of artificial grills, mechanical grills and hydraulic clearing grills. There are various structural forms such as drum type, rotary type, tooth rake type and stepped type. During the sewage treatment process, the grille is mostly used to filter large garbage and other floating objects on the water surface. The grille for sewage treatment is generally composed of coarse grille and fine The grids are composed together. In the existing grids for sewage treatme...
