Grid type sewage treatment apparatus

Abstract

The invention discloses a grid type sewage treatment apparatus. The apparatus structurally comprises a grid sewage cleaning machine, a bracket, grid bars, a secondary decontamination mechanism, rake teeth, a traction chain, a driving device, a deslagging guide pipe and a removal mechanism, fine dirt in the sewage is further filtered and fished by the grid bars through a filter screen to improve the sewage filtering treatment, an ejector rod collides with an oscillating rod to make the oscillating rod drive a water filtering attaching plate to be attached to the back surface of a filter screenthrough a connecting rod, and the water filtering attaching plate is used for ejecting out an object which is attached by dirt and is blocked on the filter screen by utilizing a thorn cone to preventthe filter screen from being blocked to influence filtering. The apparatus is used for improving the filtering treatment of fine dirt in sewage, the traction chain rotates to drive the convex teeth, and then the convex teeth drive the removal mechanism to rotate, so that the removal mechanism brushes the grid bars passing through in a reciprocating manner, the grid bars are prevented from being blocked, and the grid bars do not need to be cleaned manually again, so the manual labor cost is reduced.

Description

technical field [0001] The invention relates to the field of sewage treatment devices, in particular to a grid-type sewage treatment device. Background technique [0002] The sewage flowing in urban drainage pipes often contains a large amount of solid residues, such as waste cotton yarn, waste plastics, etc. The more these solid debris accumulate, the more they will cause the blockage of drainage pipes and affect the sanitation of the city. In order to remove the solid debris in the drainage pipe, it is necessary to use a grill to block the solid debris, and then salvage the solid debris. The work is dirty and tiring. There is also a kind of equipment used to remove sundries in sewage. The grille is flat and installed vertically. Some transmission parts are located in the sewage. The filter grille plays an important role in the sewage treatment process, but the filter grille It is easy to be blocked due to dirt adhesion, which affects the filtering effect; in order to prev...

Problems solved by technology

There is also a kind of equipment used to remove sundries in sewage. The grille is flat and installed vertically. Some transmission parts are located in the sewage. The filter grille plays an important role in the sewage treatment process, but the filter grille It is easy to be blocked due to dirt adhesion, which affects the filtering effect; in order to prevent the filter grid from being blocked, it is often necessary to manually clean it regularly, and the cleaning frequency is not easy to control. If the cleaning frequency is too high, it will consume too much manpower and material resources. If the frequency is too low, it will affect the filtering effect, and the filter grill can only roughly clean up larger solids, but cannot clean up the sewage more carefully
