Description

Municipal drainage sewage pipes

Technical Field

The utility model relates to the field of municipal drainage, in particular to a municipal drainage sewage pipeline.

Background

Municipal administration refers to various administrative tasks of the city. Also referred to as market trade transactions and city management work. Water is involved in municipal life, and a large amount of domestic or industrial wastewater is discharged correspondingly, wherein various wastewater often contains a large amount of large dirt or impurities, so that most of municipal drainage pipelines are generally provided with filtering anti-blocking structures.

However, when the anti-blocking layer is blocked by massive sundries, the drainage capacity of the pipeline is reduced, meanwhile, the filter screen cannot separate silt from entering the pipeline, the silt can be slowly accumulated in the pipeline, and finally the pipeline is blocked, so that the pipeline has room for improvement.

The Chinese patent with the application number 202022525457.8 discloses a municipal drainage and sewage pipeline which comprises a pipeline body and a sewage box, wherein a connecting pipe is arranged on the pipeline body, a connecting pipe is connected between the connecting pipe and the sewage box, and a valve is arranged on the connecting pipe; a connecting disc is arranged in the connecting tube, a screw rod is arranged at the lower end of the connecting disc, a motor is arranged at the upper end of the connecting disc, and an electric telescopic rod is also arranged at the upper end of the connecting disc; the pipe mouth of the pipe body is provided with a filter screen, the filter screen is provided with a clamping ring, and the inside of the filter screen is provided with a connecting disc. The motor is started to drive the screw rod to rotate, and the connecting disc of the motor telescopic rod is pushed to drive the screw rod to vertically move in the connecting pipe, so that the screw rod touches the sludge at the bottom of the pipe body, and then the sludge is rolled into the sludge by the screw rod and finally discharged into the sewage draining box through the connecting pipe. The filter screen can filter sundries in the sewage, and when the sundries are cleaned, the sundries in the filter screen can be lifted out only by lifting the connecting plate through the connecting rod.

However, the device still has some defects in the actual use process:

The screw rod of the device moves vertically through the electric telescopic rod pusher, the coaxiality of the screw rod and the connecting pipe can be affected by installation accuracy, sludge uniformity degree and the like, the screw rod is easy to deflect and contact with the connecting pipe, and the screw rod is prevented from rotating smoothly, and screw rod blades are damaged. In addition, when the screw rod sinks to the pipeline, the screw rod bottom is close to open state, and the lifting capacity of screw rod receives the influence of silt mobility, and when the pipeline internal water is less, the silt of deposit in the position far away from the screw rod is difficult to gather around the screw rod, leads to the screw rod idle running, and when the pipeline internal water is more, the screw rod then can lift excessive water up, extravagant energy and be unfavorable for the processing of follow-up silt.
