Abstract

The utility model relates to a sedimentation tank scraper for printing and dyeing sewage treatment. The outer surface is provided with an electric sliding block, and the lower surface of the electric sliding block is provided with a multi-stage hydraulic cylinder. The sedimentation tank scraper used for printing and dyeing sewage treatment works through the motor to drive the horizontal bridge to rotate. The two pulleys attached to the upper surface of the sedimentation tank play the role of auxiliary rotation. The horizontal bridge rotates and is evenly distributed through multiple pulleys. The supporting column drives the two first scrapers to scrape the sludge at the bottom of the sedimentation tank, so that the sludge gradually flows to the sludge collecting tank in the center of the sedimentation tank, and is finally discharged through the sludge discharge pipe. When the scraper is cleaned, the cleaning mechanism works, and gradually moves from the end of the first scraper close to the side wall of the sedimentation tank to the end of the central sludge collecting tank, scraping the sludge on the surface of the first scraper into the sludge collecting tank.
