Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a flushing device for the bottom pipeline of a rectangular secondary sedimentation tank. Background Technology

[0002] The rectangular secondary sedimentation tank has a sludge discharge pipe buried at the bottom with an opening at the top. After the sludge is scraped by the sludge scraper, it falls into the pipe and is then siphoned away. Due to the complex operation of urban wastewater treatment plants, when the MLSS in the biological tank is high and the sludge layer is thick, the siphon force is insufficient to remove the sludge from the pipe, which will cause the pipe to become blocked. However, shutting down the plant to vent and clean the pipe is time-consuming, labor-intensive, and difficult to achieve. In addition, when the existing pipe is cleaned by aeration, the gas in the pipe is prone to backflow, which affects the cleaning effect. Furthermore, the existing pipe is only connected at both ends, and because the pipe is too long, it is prone to shaking during use. Utility Model Content

[0033] The working process of this utility model is as follows: When flushing the bottom pipeline of the rectangular secondary sedimentation tank, the controller 11 controls the operation of the rotating motor 702. When the drive end of the rotating motor 702 rotates, it drives the rotating screw 703 to rotate. When the rotating screw 703 rotates, it drives the moving slider 704 to move on the side wall of the rotating screw 703. When the moving slider 704 moves, it drives the rotating shaft 708 and the rotating partition 709 to rotate through the rotating pull rod 706 and the connecting rotating rod 707. This prevents the gas from flowing back into the sludge conveying pipe 2 when the aeration pump 10 is running, thus affecting the cleaning effect of the sludge conveying pipe 2.

[0034] Place the aeration pipe 8 in the slot of the fixed sleeve 901, then align the slot on the movable sleeve 906 with the aeration pipe 8. As the movable sleeve 906 is pressed down, it drives the rotating plate 903 to rotate, so that the fixed block 905 and the connecting slot 907 cooperate with each other. Under the action of the return spring 904, the fixed sleeve 901 and the movable sleeve 906 are fixed together, thereby completing the installation of the aeration pipe 8 and facilitating the disassembly and assembly of the aeration pipe 8.
