Description

Technical Field

[0001] The utility model provides a flushing device, belongs to the technical field of sedimentation tank equipment, and particularly relates to an inclined tube flushing device for an aerated sedimentation tank. Background Art

[0002] An aerated sedimentation tank is a wastewater treatment facility that increases dissolved oxygen in the water by injecting air into the sedimentation tank, thereby improving sedimentation efficiency. This facility is usually used to remove suspended solids and organic matter from the water. Aeration not only promotes the settling of sediments, but also promotes the growth of aerobic microorganisms by increasing the oxygen content in the water, which can break down organic pollutants in the water. The design of an aerated sedimentation tank can be rectangular or circular, and the aeration intensity and time can be adjusted according to the treatment needs. This type of sedimentation tank is widely used in municipal and industrial wastewater treatment processes and is an effective water treatment technology.

[0003] After long-term use of the inclined tube sedimentation tank, some sludge may accumulate on the inclined tube, causing the inclined tube to be blocked and affecting the sedimentation efficiency. Therefore, a device that can regularly clean the inclined tube is needed. At present, the commonly used flushing method is to use a high-pressure water gun to flush the water pipe. When flushing, the water level must be lowered below the inclined tube, which will affect the operation for a long time. If the water pressure is not well controlled during flushing, the inclined tube will be broken, and a large amount of water is required, resulting in a waste of water resources. At the same time, this method requires manual flushing and is not intelligent. Utility Model Content

[0024] In this implementation plan, the main electric valve 5 is connected to the PLC controller, and time parameters can be set to regularly open the electric valve 5 for inclined tube cleaning, thus realizing automatic control. The layered distribution design of the main aeration pipe 1 and the branch aeration pipes 2 ensures that the aeration process is carried out evenly throughout the sedimentation tank, improving the cleaning efficiency and aeration effect; the main aeration pipe 1 uses a DN80 pipe, and the branch aeration pipes 2 use DN50 pipes.
