Description

Technical Field

[0001] This utility model relates to the field of sludge environmental protection treatment pond technology, and more specifically, to a sludge environmental protection treatment pond with a scraper mechanism. Background Technology

[0002] Sludge is a product of wastewater treatment. It is an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles, colloids, etc. During wastewater treatment, sludge needs to be separated in a sedimentation tank.

[0003] A search revealed that utility model patent CN216336962U discloses an environmentally friendly sludge treatment sedimentation tank, comprising a tank body. A motor is fixedly connected to the front of the tank body, and the rear end of the motor shaft passes through the inner cavity of the tank body and is fixedly connected to a rotating rod. The rear end of the rotating rod is movably connected to the back of the inner cavity of the tank body through a bearing. An agitator is fixedly connected to the surface of the rotating rod. A support plate is fixedly connected to the top of the tank body, and a water pump is mounted on the top of the support plate through a support. The input end of the water pump is fixedly connected to a telescopic pipe. This patent solves the problems of existing sedimentation tanks, which generally use a static method to allow sludge to settle before solid-liquid separation. This method is time-consuming, inefficient, and inconvenient for cleaning sludge. In addition, the fixed position of the pump head can easily cause filter clogging when the pump head is too low and inserted into the sludge, or prevent the water on the surface of the sludge from being fully extracted when the pump head is too high.

[0004] However, the aforementioned patent has the following shortcomings: when the push plate is driven by an electric telescopic rod, the sludge will affect the telescopic rod extending into the tank body, affecting its service life. Furthermore, when the sludge thickness is greater than the height of the push plate, sludge will also accumulate between the push plate and the inner wall of the tank, making it difficult to discharge and resulting in poor practicality. Therefore, we propose a sludge environmental treatment tank with a scraper mechanism. Utility Model Content

The side scraper is used to scrape the sludge attached to the side wall of the inner cavity of the pool body, and the triangular scraper is used to push the sludge at the bottom of the inner cavity of the pool body. This realizes the function of bidirectional pushing of sludge, while avoiding the sludge from affecting the driving device of the side scraper and the triangular scraper.

In addition, the second electric telescopic rod drives the end scraper to move up and down, and the end scraper scrapes off the sludge attached to the end face of the inner cavity of the pool body, ensuring that the sludge can be completely discharged, which is convenient and practical.
