AI Technical Summary

Technical Problem

During wastewater treatment, debris in the water adheres to the grid, making it impossible to collect and clean it in a targeted manner. This leads to cleaning difficulties and, over time, grid blockage, affecting the water flow rate.

Method used

It adopts a structure linking conical rods and grid belts. The matrix-arranged conical rods vertically penetrate the water flow to enhance the garbage hooking ability, and the grid belt circulating conveyor chain driven by the motor lifts the garbage to the top. Combined with the synergistic effect of rollers and flexible scrapers, it realizes the directional transportation and zero-residue stripping of garbage. At the same time, the lifting mechanism of frame plate and threaded screw realizes the solid-liquid separation of garbage and convenient cleaning.

Benefits of technology

It achieves efficient interception and targeted transport of sewage and garbage, improves garbage capture rate, solves grid clogging problem, and shortens maintenance time and improves water flow rate through automated cleaning process.

Abstract

The utility model relates to the technical field of sewage treatment, and solves the problems that during sewage treatment, garbage in water is attached to a grid, directional cleaning and collection cannot be realized, inconvenience is brought to later cleaning, the cleaning difficulty is increased, the grid is blocked after a long time, and the water passing rate is influenced. The grid for sewage treatment comprises a gantry frame, fixing plates are symmetrically arranged on the inner side wall of the gantry frame, a motor A is arranged at the top end of one fixing plate, the output end of the motor A penetrates through the fixing plate to be fixedly connected with a rotating shaft A, and the surface of the rotating shaft A is sleeved with a grid belt. The side, away from the rotating shaft A, of the grid belt is sleeved with a rotating shaft B, the two ends of the rotating shaft B are rotationally connected with the fixing plates through bearings, and a plurality of conical rods are arranged on the surface of the grid belt. A trapezoidal frame is fixed to the top of the gantry frame, a motor B is arranged on the side face of the trapezoidal frame, and the output end of the motor B penetrates through the trapezoidal frame and is fixedly connected with a roller.
