Grating well integrated water treatment device convenient to overhaul

Abstract

The invention relates to a grating well integrated water treatment device convenient to overhaul. The device comprises a water treatment device which is arranged in a grating well and is communicatedwith a water inlet end of the grating well. The water treatment device comprises a crushing grillage machine, a screw press elevator and a connecting tank body connected with a slag outlet of the crushing grillage machine and a slag inlet of the screw press elevator. The slag outlet end of the crushing grillage machine is propped against the slag inlet end of the connecting tank body through a wear-resistant material for sealed communication; the slag outlet end of the connecting tank body is communicated with a slag inlet of the screw press elevator in a hasp mode, the two sides of the crushing grillage machine and the side wall of the grid well are installed in a sliding mode through guide rails in the depth direction of the grid well, and a hoisting steel cable is further arranged at the top of the crushing grillage machine. According to the invention, garbage and grid slag at the water outlet end of the grid well are ensured to meet the design requirements, the problems of fallingof garbage and grid slag and sewage leaching are eliminated, and the crushing grillage machine can be prevented from going down to the well to be overhauled.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a grid well integrated water treatment device which is convenient for maintenance. Background technique [0002] In water treatment, garbage and grid slag removal and cleaning are important links. The technology currently used is to install a grid machine in the grid well to lift the garbage and grids to the ground belt conveyor or screw conveyor, and then the belt conveyor or screw conveyor will transport the garbage and grids to the garbage bucket for transportation. [0003] Although the above-mentioned combination of equipment can remove garbage and grid slag in the water, it has serious adverse effects on the surrounding environment due to garbage, grid slag falling and sewage leaching during the production process; secondly, the grid well is mainly divided into coarse For grill wells and fine grill wells, in consideration of the lifting of garbage and gri...

AI Technical Summary

Problems solved by technology

[0003] Although the above-mentioned combination of equipment can remove garbage and grid slag in the water, it has serious adverse effects on the surrounding environment due to garbage, grid slag falling and sewage leaching during the production process; secondly, the grid well is mainly divided into coarse For grill wells and fine grill wells, in consideration of the lifting of garbage and grid slag, generally a coarse screen machine is installed in a coarse screen well, and the installation angle is generally about 60°, while a fine screen machine is installed in a fine screen well. The installation angle is generally about 45°, and the coarse and fine grid well pretreatment structures require a large installation space and a certain floor area; in addition, limited by equipment manufacturing costs, installation and management difficulties, the coarse grid well The installation depth of the grid machine generally does not exceed 10 meters, otherwise a transfer platform needs to be designed to solve the problem of garbage and grid slag lifting

[0004] For the Chinese patent, the publication number is CN208292683U, a grid well integrated water treatment device, which can better solve the above problems, but its broken grid machine, connecting box, and screw press hoist are fixedly connected in one. When the broken grid machine needs to be overhauled, it needs to be overhauled in the grid well, which is extremely inconvenient, time-consuming and laborious, and there is no non-down-well maintenance method for the grid machine in the prior art
