Pipeline device for sewage treatment by utilizing negative pressure adsorption principle

Abstract

The invention relates to the technical field of sewage treatment, and discloses a pipeline device for sewage treatment by utilizing a negative pressure adsorption principle. The pipeline device includes a separation pipe; a sewage pipe is movably connected to the exterior of the separation pipe; a leakage-proof pad is fixedly connected to one end, close to the separation pipe, of the sewage pipe;an airflow pipe is movably connected to the exterior of the separation pipe; a rack is fixedly connected to the exterior of the separation pipe; a threaded rod is meshed with the exterior of the rack;a limiting plate is fixedly connected to the exterior of the threaded rod; a rotating column is fixedly connected to the exterior of the limiting plate, and a motor is fixedly connected to the rightside of the rotating column. Under the interaction of a first plate, a second plate, a hydraulic rod, a filter screen and a water treatment layer, it can be guaranteed that when sewage enters the separation pipe, the first plate and the second plate are opened inwards, solid waste cannot be disengaged during rotation and can be attracted by airflow to enter the airflow pipe to be taken away untilthe solid waste rotates to the airflow pipe, solid-liquid separation is truly achieved, the solid waste cannot enter subsequent treatment steps, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a pipeline device for sewage treatment using the principle of negative pressure adsorption. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. Sewage treatment can be divided into three types according to its function: physical method, biological method and chemical method. The physical method mainly uses physical action to separate the insoluble substances in the sewage, and does not change the chemical properties during the treatment process; the biological method uses the metaboli...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a pipeline device for sewage treatment using the principle of negative pressure adsorption, which has the advantages of rapid solid waste treatment, solid-liquid separation, and high efficiency, and solves the problem of manual or manual waste removal when filtering solid waste. Operate the machine to clean once. This operation will cause the accumulation of garbage to have a great impact on the water flow rate of the sewage, which will reduce the speed of sewage treatment, which is not conducive to the efficiency of sewage treatment. If the sewage brings too much solid waste, It is very easy to cause blockage of the pipeline, and the sewage treatment device will stop running, which will cause damage to the sewage treatment device and cause a large amount of sewage to accumulate.
