Through mechanical movement or the force of water flow, the sludge is pushed to one side of the pool for further treatment or removal. The function of the scraper is to ensure that the bottom of the sewage pool remains clean and prevent sludge accumulation from affecting the water quality in the pool and the operating efficiency of the equipment.

Therefore, after the scraper blade is installed, it is not easy to adjust the angle of the scraper blade and the pressure between the scraper blade and the bottom of the pool. As a result, the bottom of the scraper blade may be worn when used for a long time, resulting in failure to completely remove the sludge. In addition, the scraper blade has an unsatisfactory contact angle, which will also affect its cleaning effect and sewage treatment efficiency. Utility Model Content
