Anti-blocking grating for water purification

Abstract

The invention discloses an anti-blocking grating for water purification, relates to the technical field of filter devices for sewage treatment, and aims to solve the problem that sewage contains lotsof impurities, so that grating holes are always blocked, resulting in low water velocity and reduced sewage treatment efficiency. One side of a secondary filtering grating plate is provided with a primary filtering grating plate, and the primary filtering grating plate is fixedly connected with the secondary filtering grating plate through screws; both sides of the primary filtering grating plateare provided with water diversion plates, anti-blocking brush arms are arranged between the secondary filtering grating plate and the primary filtering grating plate, both sides of the anti-blocking brush arms are provided with anti-blocking brush arm fixing links, the middle part of each anti-blocking brush arm is provided with a rotating shaft, impellers are arranged outside each rotating shaft,brush plates are arranged both above and below each rotating shaft, one side of each brush plate is provided with anti-blocking brush hair, and a brush plate connecting rod is arranged between each brush plate and the corresponding rotating shaft.

Description

technical field [0001] The invention relates to the technical field of filter devices for sewage treatment, in particular to an anti-clogging grid for water purification treatment. Background technique [0002] Pollutants in sewage generally exist in three forms: suspended (including floating) state, colloid and dissolved state. The physical treatment of sewage is generally called the solid-liquid separation treatment of wastewater, and the grille is the main auxiliary equipment for solid-liquid separation in sewage treatment. The grid is generally composed of a group of parallel grid bars, which are placed obliquely at the inlet of the sump of the pump station. According to the shape, the grid can be divided into two types: flat grid and curved grid. The plane grille is composed of bars and frames. Curved grilles can be divided into two types: fixed curved grilles and rotating drum grills. [0003] At present, the grids on the market are generally simple to block the lar...
