Drainage device used for collecting municipal sewage

Abstract

The invention discloses a drainage device used for collecting municipal sewage. The key points of the technical scheme are as follows: the drainage device comprises a water collecting tank, wherein a vacuum tube is arranged in the water collecting tank, a support rod is rotatably arranged on the outer wall of the vacuum tube, a cleaning hopper used for fishing up impurities on the surface of the sewage is rotatably arranged on the support rod in a form of surrounding the support rod, a collecting box used for receiving the impurities falling from the cleaning hopper is further arranged on the support rod, a first drive part used for driving the support rod to rotate is arranged on the vacuum tube, and a second drive part used for driving the cleaning hopper to rotate is further arranged on the support rod. When the impurities in the water collecting tank need to be treated, the cleaning hopper fishes up the impurities floating on the surface of the sewage, along with the rotation of the cleaning hopper, the impurities in the cleaning hopper fall into the collecting box under the effect of gravity to be collected, due to the adoption of the cleaning hopper, the first drive part and the second drive part, the impurities on the surface of the sewage are cleaned, the cleaning efficiency is high, the automatic cleaning is realized, and the cleaning cost is reduced.

Description

technical field [0001] The invention relates to the technical field of municipal drainage, more specifically, it relates to a drainage device for collecting municipal sewage. Background technique [0002] Residential sewage collection is an important part of municipal drainage and sewage treatment. Its purpose is to collect the sewage discharged by multiple drainage units in the community and transport it to the main pipeline for discharge or discharge it after treatment through sewage treatment facilities. [0003] The invention patent with the publication number CN104652573A provides a vacuum drainage system technology and device for municipal sewage collection. An emptying pipe connected to the air is installed at the end of the vacuum pipe, and the opening and closing of the emptying pipe is controlled. A certain amount of air increases the pressure difference between the front end and the rear end of the water column, so that the water column at the end can move forward...

AI Technical Summary

Problems solved by technology

[0004] When working, the sewage at the drainage point first flows into the nearby water collection tank through gravity flow. There is a vacuum tube in the water collection tank. The vacuum tube will pump out the sewage in the water collection tank. There is a set of nets to intercept debris. When the debris in the water collection tank accumulates to a certain amount, it needs to be cleaned manually. Usually, a scenic spot covers an area of ​​12.5 hectares, and 11 water collection tanks need to be installed at a time. For clearing, 11 water collection tanks need to be cleaned, which consumes a lot of manpower and material resources, making cleaning inconvenient and costly
