The invention discloses a vortex air-flotation
sediment scraper, which comprises a
machine body, the left side of the top of the
machine body communicates with a water inlet
pipe, the right side of the bottom of the
machine body communicates with a water outlet
pipe, and the bottom of the left side of the inner cavity of the machine body is fixedly connected with a fixing block; a clamping slot isformed in the right side of the fixing block, a clamping block is disposed at the inner side of the clamping slot, and a filter plate is fixedly connected to an end, away from the inner cavity of theclamping slot, of the clamping block; and a fixing frame is fixedly connected to the bottom of the right side of the inner cavity of the machine body, and a spring is fixedly connected to the right side of the inner cavity of the fixing frame. The
sediment scraper of the invention can drive a
threaded rod to rotate by arrangement of a motor, and at the same time, a thread sleeve moves by cooperation of the
threaded rod and the threaded sleeve; and through arrangement of the threaded sleeve, a scraping plate is driven to move to clean impurities on the surface of the filter plate, thereby facilitating
sewage treatment, and meanwhile solving the problem that the
sewage treatment efficiency is reduced due to the fact that an existing
sediment scraper cannot completely remove impurities on the surface of a filter plate.
