  • Sludge handling system with rotating discharge device for discharging sludge from a bin
    Patent number: 8662354
    Abstract: A sludge handling system includes at least one bin that receives sewage sludge at an upper end thereof, and that has sloped side wall(s) at the lower end thereof, for directing sewage sludge toward a generally central discharge opening. A rotating discharge device is provided in the form of a thin foil or blade that is rotationally driven to scrape along the sloped side wall(s) of the bin, scraping sludge therefrom, to keep the sludge from adhering to sloped portions of the bin, and to direct sludge out the discharge opening. The rotating discharge device is mounted on and carried by a generally cylindrical rotating table that is motor-driven. A generally cylindrical seal is also carried by the rotating table, and slides along the inside of a sludge discharge chute, at the discharge opening of the bin.
