Abstract

The invention discloses a grid device for sewage treatment and a using method thereof, and relates to a grid device and a using method thereof. A coarse grid body consisting of a plurality of wavy rigid metal strips is arranged in a coarse grid plate; concave-convex positions are staggered to form elliptical openings; vertical rods on two sides of a coarse grid frame are correspondingly provided with penetrating rings; and a left supporting plate and a right supporting plate are fixed to two sides of the coarse grid plate, the middle is hollow, a sliding groove is formed behind the left supporting plate and the right supporting plate; a fine grid plate is inserted into the sliding groove; a steel wire rope with a brush is bent in a snake shape and penetrates through the multiple rows of elliptical openings and the corresponding penetrating rings; the head end and the tail end are oppositely turned and then fixedly connected, each bending point and turning point support a rotating wheel, the rotating wheel located at the upper turning point is provided with a driven belt wheel, the U-shaped grid groove is provided with an inserting groove into which the coarse grid plate is inserted, and a driving belt wheel of a driving motor is connected with the driven belt wheel through a belt. The coarse grid body is not prone to being blocked, the snakelike bent steel wire rope with a brush is arranged and can be controlled by the driving motor to move, and the blockage is prevented by the brush.

Description

technical field [0001] The invention relates to a grid device and a method for using the same, in particular to a grid device for sewage treatment and a method for using the same, belonging to the technical field of sewage treatment engineering. Background technique [0002] The grille device is a small device commonly used in sewage treatment projects to intercept impurities in sewage. It is mainly used for preliminary filtration of sewage to prevent more impurities from entering the subsequent fine treatment and causing a large load on the fine treatment equipment. Traditional grill devices are generally flat grills, which are easy to block some holes by larger garbage, reducing the processing efficiency. Therefore, how to improve the anti-blocking performance of the grille device and how to intercept impurities in the sewage for a long time has been the key to the research of the grille production designers. Contents of the invention [0003] The object of the present ...
