Problems solved by technology

Then, due to seasonality, weather or changes in production and life, the flow of water channels and the content and size of solid pollutants will fluctuate. If the load exceeds the rated working range of the grill machine, it will cause blockage of the grill and make the grill The grid becomes the bottleneck of the canal; and during the water shortage season, people hope to store water in the canal

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] refer to Figure 1 to Figure 4 As shown, it is a curved surface grid cleaning machine with adjustable grid bar spacing according to the present invention, which includes a main scraper 1, an auxiliary scraper 5, a grid 6, a quadrilateral telescopic frame 8, a push rod 10, and a grid storage layer 13 , hinge 16;

[0024] The grille 6 is an arc-shaped curved surface. The concave surface of the grille 6 is used as the water-facing side to face the water flow. The top of the convex side of the grille 6 is provided with a garbage storage bin 7. The arc center of the arc surface of the grille 6 is provided with a main scraper. Plate 1, the main scraper 1 is driven to rotate by the main motor 2 and the end matches the curved surface of the grid 6;

[0025] The grille 6 is arranged at certain intervals by the grille bars 12, and the upstream side and the backwater sid...

Abstract

The invention provides a curved-surface grid trash remover with adjustable grid bar intervals and belongs to the technical field of water pollution treatment. The trash remover mainly comprises a main scraper, a grid, quadrilateral telescopic frames, push rods and hinges. The grid is an arc-shaped curved surface, the concave surface of the grid serves as an upstream side to bear down on currents, the upstream side and the downstream side of the grid are fixed to rotary shaft positions of the quadrilateral telescopic frames respectively through the hinges, and the ends of the quadrilateral telescopic frames are connected with motors through the push rods. Equal-range adjustment of the grid bar intervals is achieved through synchronous telescopic motion of the quadrilateral telescopic frames of the upstream side and the downstream side, and then the grid intercepting efficiency is adjusted; the grid rotates through non-synchronous telescopic motion of the quadrilateral telescopic frames, and then water storage is achieved. The curved-surface grid trash remover is simple in principle, reasonable in structure, reliable in running and high in practicality, and has grid intercepting and water storing functions.

Description

technical field [0001] The invention relates to the technical field of water pollution treatment, and is especially suitable for grid cleaning of solid pollutants in water. Background technique [0002] The grid cleaning equipment is generally used on the water inlet channel of sewage treatment or at the entrance of the sump of the lifting pump station. Process load, and play a role in protecting pumps, pipelines, instruments, etc. [0003] The screen machines commonly used in the sewage treatment industry mainly include rotary type, rake type and rotary arm type. [0004] Among them, the rotary grille cleaning machine adopts rake teeth to assemble a set of rotary grille chains. Driven by the motor, the rake tooth chains rotate against the direction of water flow, which can continuously and automatically intercept and remove various sundries in the water channel. High efficiency, high separation efficiency, and the operation interval of equipment can be adjusted arbitraril...
