Anti-blocking regulating valve for sewage pipeline of municipal construction site

Abstract

The invention relates to the technical field of construction sewage treatment, and particularly relates to an anti-blocking regulating valve for a sewage pipeline of a municipal construction site. The inner walls of the upper end and the lower end of a pipeline shell are slidably connected with regulating rods, and a first bevel gear is fixedly connected to the position, located in the pipeline shell, of one end of each regulating rod; the outer surface of each first bevel gear is engaged with a double-sided gear, and the outer surface of each double-sided gear is engaged with a second bevel gear; the outer wall of each double-sided gear is fixedly connected with a limiting ring plate, and the outer surface of each limiting ring plate is fixedly connected with a limiting shaft; and stirring blades are fixedly connected to the positions, located in the limiting shafts, of the outer surfaces of the second bevel gears. The stirring blades connected to the second bevel gears revolve along the double-sided gears and rotate at the same time, silt in the pipeline shell can be stirred to be in a suspended state advantageously and flows out along with sewage in the pipeline, the phenomenon of deposition of the sewage in the pipeline can be effectively prevented, and pipeline blocking is avoided.

Description

technical field [0001] The invention relates to the technical field of building sewage treatment, in particular to an anti-clogging regulating valve for municipal building site sewage pipelines. Background technique [0002] The sewage generated on the construction site mainly contains a large amount of sediment. The sediment can be reused after a series of sedimentation treatment to avoid the waste of resources. The sewage is finally passed through a series of sewage pipes into the sewage treatment tank Subsequent treatment is carried out in the pipeline, and the pipeline is connected by multiple switch valves to facilitate the control of sewage. [0003] Because the construction site sewage contains a lot of sediment, and when the sediment passes through the sewage pipe, it will settle. If the flow rate of the water is small, a large amount of sediment will be deposited on the inner wall of the pipe, and the long-term accumulation will block the pipe. , it is difficult to...

Problems solved by technology

[0003] Because the construction site sewage contains a lot of sediment, and when the sediment passes through the sewage pipe, it will settle. If the flow rate of the water is small, a large amount of sediment will be deposited on the inner wall of the pipe, and the long-term accumulation will block the pipe. , it is difficult to clean up in the later stage, and there are gases produced by anaerobic respiration of bacteria and microorganisms in the sewage. If a large amount of gas inside the pipeline cannot be discharged, it will cause damage to the pipeline. Therefore, those skilled in the art provide a sewage pipeline for municipal construction sites Anti-clogging regulating valve, to solve the problems raised in the above-mentioned background technology
