Municipal road sewer decontamination and dredging device

Abstract

The invention discloses a municipal road sewer decontamination and dredging device which comprises a sewer pipeline, wherein a sewage circulation cavity is arranged in the sewer pipeline, a decontamination block is arranged in the sewage circulation cavity, a telescopic device is arranged in the decontamination block and comprises bilaterally symmetrical installation blocks, and the installation blocks can be tightly abutted against the inner end wall of the sewage circulation cavity, so that the decontamination block is fixedly installed in the sewage circulation cavity. According to the invention, an integral device is driven by an advancing device to move to a position in the pipeline which needs to be subjected to decontamination and dredging, and then is suspended and fixed in the pipeline by a stretching device, a cutting knife rotates to cut and crush congestion or crush sludge, and the cutting knife can lift and move to work, so that the working area of the pipeline is enlarged, the decontamination and dredging work of the pipeline can be accelerated, and the dredging work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a decontamination and dredging device for municipal road sewers. Background technique [0002] The traditional urban sewer decontamination and dredging work uses high-pressure water to impact the congested objects in the pipeline, so that the congested flow can be circulated, so as to complete the dredging work. This method not only wastes water resources, but also requires the assistance of high-pressure water jetting equipment. The area and space of the area to be dredged are limited, and when the blockage hits the next sewer, it is easy to cause the blockage of the next sewer. Secondly, after the sewer pipe is bent, the water pressure of the high-pressure water will be reduced, and its impact on the blockage will be affected. If it is reduced, the dredging work is difficult and time-consuming, and even requires the assistance of the staff to clear the congestion in th...

Problems solved by technology

[0002] The traditional urban sewer decontamination and dredging works through the impact of high-pressure water on the congested objects in the pipeline to make the congested flow unblocked, so as to complete the dredging work. This method not only wastes water resources, but also requires the assistance of high-pressure water injection equipment, which is large in size and subject to The region and space of the area to be dredged are limited, and when the congested objects hit the next sewer, it is easy to cause the blockage of the next sewer. Secondly, after the sewer pipe is bent, the water pressure of the high-pressure water will be reduced, and its impact on the congested objects Reduced, resulting in difficult and time-consuming dredging work, and even requiring the assistance of staff to go down to the pipeline to clear the congestion, poor working environment, resulting in low work efficiency
