A grid decontamination machine

Abstract

The present invention provides a grille decontamination machine, and relates to the technical field of sewage treatment equipment. The grille decontamination machine comprises a driving device and a grill machine, wherein the grilling machine comprises a driving wheel, a driven wheel and an annular conveying device, the driving wheel is driven by the driving device, the driving wheel is connectedwith the driven wheel through the annular conveying device; the annular conveying device is provided with rake rack rows and a sliding part, each rake rack row comprises a plurality of rake racks thesliding part sleeves the rake rack row, and can move back and forth along the axial direction of the rake racks, and the rake rack rows are arranged around the outer surface of the annular conveying device in multiple rows and can rotationally move along with the annular conveying device. The grille decontamination machine can effectively remove solid debris stuck in gaps of the rake rack rows andensures the decontamination effect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a grid decontamination machine. Background technique [0002] The grid decontamination machine mainly separates the suspended substances in the sewage through physical separation, such as waste paper, branches, fiber sundries, etc. When the existing grid decontamination machine is working, driven by the motor, it rotates The chain rotates from bottom to top. When the row of rake teeth on the traction chain turns to the upper part of the machine, the solid debris on the row of rake teeth falls off to the collection tank by its own weight. However, due to the complex water quality of sewage and many sundries, some daily necessities and fiber sundries are caught in the gaps of the rake teeth, which cannot fall off by themselves relying solely on their own gravity, which not only leads to blockage of the gaps between the rake teeth and reduces the interception rate...

Problems solved by technology

However, due to the complex water quality of sewage and many sundries, some daily necessities and fiber sundries are caught in the gaps of the rake teeth, which cannot fall off by themselves relying solely on their own gravity, which not only leads to blockage of the gaps between the rake teeth and reduces the interception rate of the grill machine, It will also cause some debris to enter the downstream link without being intercepted, resulting in unsatisfactory decontamination effect
