The utility model belongs to the technical field of secondary sedimentation tanks, in particular to a novel sludge hopper for a secondary sedimentation tank, which is characterized in that a sludge discharge port is arranged at the bottom of a secondary sedimentation tank body, a sludge discharge pipeline corresponding to the sludge discharge port is arranged at the bottom of the secondary sedimentation tank body, a plurality of first sludge discharge holes are arranged at the bottom of the sludge discharge pipeline, and the inner side wall of the sludge discharge pipeline is connected with an adjusting plate in a sliding manner; the adjusting plate is provided with a second sludge discharge hole corresponding to the first sludge discharge hole, the adjusting plate is driven by a power device, the secondary sedimentation tank body is provided with a sludge scraping assembly, and the device has the beneficial effects of accurate sludge discharge control, efficient sludge scraping, good adaptability and the like.

This utility model discloses a sludge scraping device for a wastewater treatment sedimentation tank, relating to the field of wastewater treatment technology. It includes a sedimentation tank body, a lower sludge scraper, and an upper sludge scraper. The lower and upper sludge scrapers are installed on the inner walls of all four sides of the sedimentation tank body. A T-shaped groove is formed on the upper side of the lower sludge scraper, and the upper sludge scraper is installed above it. A T-shaped slider is fixed to the bottom of the upper sludge scraper, and the T-shaped slider is slidably connected to the T-shaped groove. A cleaning brush assembly is installed inside both the lower and upper sludge scrapers. The cleaning brush assembly includes a mounting cylinder, a spring, a limiting block, a connecting rod, and a cleaning brush. In this wastewater treatment sedimentation tank sludge scraping device, the cleaning brush is constantly pushed outward by the spring, allowing it to closely adhere to the inner wall of the sedimentation tank body. This enables the cleaning brush to assist the scraper in removing and cleaning the sludge from the inner wall of the sedimentation tank body, effectively improving the sludge scraping efficiency and effect.
