Description

Technical Field

[0001] This utility model relates to the field of suction and scraping sludge machines, and more specifically, to a peripheral drive suction and scraping sludge machine for sewage treatment. Background Technology

[0002] Wastewater treatment is a purification process aimed at bringing wastewater up to the required water quality for discharge into a water body or for reuse. This process is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly integrated into the daily lives of ordinary people.

[0003] Chinese patent application number CN217139328U discloses a peripheral drive suction and scraper for sewage treatment, specifically relating to the field of suction and scraper.

[0004] In the above technical solution, the cleaning size of the cleaning component is adjustable, which greatly improves the applicability of the device. However, in actual use, as sludge is continuously squeezed into the sludge bin, since the sewage discharge process usually does not remove the upper layer of clean water, if the sludge pump device directly sucks out the dirt in the sludge bin, a large amount of clean water will be carried out at the same time, resulting in waste; in addition, some sludge in the sedimentation tank will be pushed into the water again by the water flow, and the diffused sludge needs to be re-sedied afterward; based on this, this application proposes a peripheral drive suction sludge scraper for sewage treatment.
