Abstract

Sludge scraping mechanism for enclosed sedimentation tanks (1) for wastewater treatment comprising a semi-rigid sludge scraper blade (12) connected rigidly with a support arm (13) to a traversing wagon (15) on wheels (16). The scraping mechanism automatically positions itself in an upright position during the scraping cycle and in an angled position during the return cycle by means of the horizontal U-profile (14) guide rails, and another switching mechanism (14B, 21B, 22B) at the outlet end of the guide rails (14). The guide rails (14) are constructed in u-profiles with the openings facing each other horizontally and serve as supports for the traversing wagon (15) on wheels (16) that moves back and forth during the scraping cycles.
