AI Technical Summary
Existing wastewater treatment flotation tanks are inefficient at removing fine particles and adhesives from the water surface, as each scraper needs to work continuously, resulting in insufficient efficiency.
It employs multiple scraping tooth mechanisms, which are driven by chains and shafts to move the scraping teeth. Combined with the design of guide plates and springs, it realizes the cyclical movement and self-cleaning of the scraping teeth, and quickly removes fine particles and adhesive substances from the water surface.
It improves the cleaning efficiency of fine particles adhering to the water surface. The scraping teeth shake off and collect the residue into the collection chamber during the self-cleaning process, achieving a highly efficient solid-liquid separation effect.
