Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment pool cleaning, in particular to a device for cleaning sludge on the side wall of a sewage treatment pool. Background Art

[0002] Wastewater treatment refers to the removal or transformation of pollutants in sewage through physical, chemical and biological methods to meet emission standards or reuse purposes. The sewage treatment tank is the core part of the sewage treatment facility, used to collect, store and treat sewage. During the long-term use of the sewage treatment tank, sludge may accumulate on its side walls, mainly due to the sedimentation characteristics of the sludge, the unevenness of air and water flow, and the change of sludge density. This sludge accumulation will not only reduce the treatment efficiency and equipment performance, but may also cause odor and harmful gas emissions.

[0003] Upon investigation, a Chinese patent discloses a sludge cleaning device for the side wall of a sewage treatment pool (publication number: CN220532515U), which includes a base plate, a shell, a servo motor, a first rotating shaft, a first transmission assembly, a crawler, a fixed rod and a brush rod. The shell is fixedly connected to the base plate, and a servo motor is installed inside the shell. The first rotating shaft is rotatably provided on the front and rear sides of the shell, and a first transmission assembly is provided between the output shaft of the servo motor and the two first rotating shafts. A crawler is connected between the left and right ends of the two first rotating shafts. Fixed rods are fixedly connected to the left and right sides of the base plate, and a brush rod for cleaning sludge is rotatably provided between the two fixed rods. An adsorption mechanism is also included, and an adsorption mechanism for adsorption is provided on the crawler.

[0004] In the above patent, the base is closed and opened by continuously manually moving the slider inward and outward, increasing and decreasing the air pressure inside the suction cup, so that the suction cup can intermittently adsorb on the side wall of the sewage treatment tank when the device moves, preventing the device from falling from the side wall of the sewage treatment tank, thereby facilitating the cleaning of the side wall of the sewage treatment tank and improving the cleaning efficiency of the sewage treatment tank.

[0005] However, the device does not have a recovery device for the cleaned sludge. The cleaned sludge falls into the sewage pool and settles again at the bottom of the pool, causing the thickness of the bottom sludge layer to increase, making subsequent cleaning work more difficult.

[0006] Therefore, the utility model provides a sludge cleaning device for the side wall of a sewage treatment tank to solve the above problems. Utility Model Content
