Decontamination and purification device for municipal drainage pipeline opening

Abstract

The invention discloses a decontamination and purification device for a municipal drainage pipeline opening. The decontamination and purification device structurally comprises a water inlet, an operation box, a connecting flange, a support, a sewage draining outlet and a sewage draining valve, wherein the water inlet is fixedly connected with the operation box, the operation box is connected with the connecting flange in an embedded mode, the support and the operation box are of an integrated structure, the sewage draining outlet is connected with the operation box in an embedded mode, and the sewage draining valve is mechanically connected with the operation box. Column bodies connected with a buffer net are arc-shaped columns, an arch-shaped filtering structure is formed by splicing the arc-shaped column bodies, the arch-shaped structure has pressure resistance, and when the impact force of drainage acts on a filter net, the filter net is not prone to deformation; and an overturning shaft is arranged on an assembling shaft of the filter net, hollow openings formed in extending structures on the two sides of the overturning shaft are different in position installation, the contact surfaces, acting on the overturning shaft, of the drainage are different, the impact force of the drainage can push the overturning shaft to rotate, the flow speed of the drainage passing through the filter net is reduced, and therefore the impact force of the drainage on the filter net is relieved.

Description

technical field [0001] The invention relates to the field of municipal gardens, in particular to a decontamination and purification device for municipal drainage pipe outlets. Background technique [0002] The decontamination and purification equipment at the mouth of municipal drainage pipes is called pipeline filter, which can be divided into vertical decontamination and purification equipment, horizontal decontamination and purification equipment, and vertical decontamination and purification equipment can be divided into vertical straight-through decontamination equipment according to the different pipelines. Pollution purification equipment, vertical corner decontamination purification equipment, etc.; [0003] In the prior art, the decontamination and purification equipment at the mouth of the drainage pipe filter out the impurities in the drainage through the filter screen inside the equipment. On the filter screen, the connection end between the grid and the grid wi...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the decontamination and purification equipment at the mouth of the drainage pipe filter out the impurities in the drainage through the filter screen inside the equipment. On the filter screen, the connection end between the grid and the grid will fall off and tilt, causing the filter screen to deform, resulting in a larger filter aperture, and the equipment cannot completely filter out impurities such as sludge in the drainage.
