Drainage device for preventing backflow of sewage and drainage method of drainage device

Abstract

The invention belongs to the technical field of rapid drainage treatment of sewage pipelines, and discloses a drainage device for preventing backflow of sewage and a drainage method of the drainage device. The drainage device is configured together with drainage equipment through a main sewage pipe, an anti-odor drainage pipe is arranged, the efficient drainage effect on waste water in a sewage pipeline is achieved, and meanwhile, odor in the sewage pipeline is further effectively prevented from scattering into a residence along the main sewage pipe. By arranging an alarm device, a control device, an actuator and other parts in the drainage device, it is ensured that the phenomenon can be detected at the fastest speed after the backflow in the sewage pipeline occurs, so that the backflow sewage in the sewage pipeline is successfully discharged, the loss rate of the sewage pipeline is significantly reduced, the repair labor loss is reduced, and thus the quality of national life is improved. The drainage method is simple in steps and convenient and quick, the effect of rapid drainage is achieved through a simple linkage method, and high efficiency and very high practicability are achieved.

Description

technical field [0001] The invention belongs to the technical field of rapid drainage treatment of sewage pipes, and in particular relates to a drainage device and a drainage method for preventing sewage backflow. Background technique [0002] In ordinary high-rise residential buildings, there are many pipelines for discharging daily sewage, and so many sewage pipelines will be uniformly converged from the high-rise to the first floor and the underground sewage storage tank. At the same time, because there are often a large number of clogs left in sinks such as kitchens and bathrooms in various households, these remnants and clogs will follow the sewer and drainage pipes along with the movement of sewage, which will easily cause the probability of sewage pipes being blocked. Thereby make sewer overflow (reverse choking water) phenomenon become more common problem in the life, meanwhile, the problem that very easily causes blockage about sewage pipe has also been subjected to...

AI Technical Summary

Problems solved by technology

The improvement of this structure can only be used to prevent the overflow of the drainage pipe when there is no kitchen sewage and waste water, and it cannot be well solved for the problem of preventing the backflow of the drainage pipe and effectively dual drainage and discharge of sewage and waste water at the same time. At the same time, the structure is not equipped with an anti-odor structure to prevent the pollution of the family environment caused by the foul smell in the sewage pipes
