Sewage purification filter grid with surface cleaning structure

Abstract

The invention discloses a sewage purification filter grid with a surface cleaning structure. The sewage purification filter grid comprises a supporting plate, wherein grid main bodies are uniformly arranged in the middle of the supporting plate; sliding rods are symmetrically fixed to the left side and the right side of the back face of the supporting plate, the outer side of each sliding rod is sleeved with a sliding sleeve, a rotating shaft is inserted between the back faces of the two sliding sleeves through a support, turbine blades are fixedly installed on the outer side of the middle ofthe rotating shaft, and first bevel gears are fixedly installed on the outer walls of the left side and the right side of the rotating shaft. The turbine blades are arranged on one side of the back face of the supporting plate; the first bevel gears and second bevel gears are arranged and are in meshed connection through teeth, transmission of a belt wheel transmission mechanism and meshed connection between a worm and a worm wheel are matched, through pushing of water flow, the turbine blades can rotate to drive a scraping and brushing frame to rotate, and therefore scraping and brushing cleaning is conducted on the grid body through a brush installed on the scraping and brushing frame.

Description

technical field [0001] The invention relates to the technical field of filter grid equipment for sewage purification, in particular to a filter grid with a surface cleaning structure for sewage purification. Background technique [0002] With the development and progress of society, the pollution caused by people's life and production process to the surrounding environment is becoming more and more serious.
