AI Technical Summary
Existing sewage treatment dredging devices have difficulty accurately adhering to the sludge surface in different operating scenarios, resulting in incomplete cleaning, easy clogging of filter components, and affecting the continuity and efficiency of dredging operations.
It adopts an adjustable-angle scraping and crushing mechanism, combined with a motor-driven threaded rod and telescopic rod, to achieve self-cleaning of the filter plate and dynamic adaptation to sludge. Equipped with a sludge pump and crushing blades, it ensures effective sludge scraping and filtration, avoiding clogging.
It improves sludge coverage and suction efficiency, prevents filter plate clogging, ensures smooth sludge flow, adapts to complex pool bottom conditions, reduces the risk of pipeline blockage, and achieves automated control and efficient sludge removal.
