ABSTRACT:
A waste removal flushing system for storing and selectively outputting water for flushing animal waste from a waste collection surface of a hog house or other animal pen. The flushing system includes a tank with a plurality of water output openings. A flushing valve is slidably mounted at each water output orifice on a valve guide rod that extends from a bottom surface through the water output opening, and into the tank. The valves are slidably positionable on the guide rods between a closed position where water in the tank is prevented from passing through the water output openings and an open position where water in the tank passes through the water output openings. Each valve is sized to extend beyond the outer periphery of the output opening and is sized to seat with a seating surface surrounding the output opening such that a water-tight seal is formed when the valve is in the closed position. The valve is positioned between the open and closed positions by a dual-acting, pneumatic cylinder. The pneumatic cylinder is coupled to the valve through a tubular sleeve extending from the valve head. A controller coupled between an air supply and the pneumatic cylinder provides for positioning of the valves at selected times. The controller includes a solenoid-operated, air valve for controlling the pneumatic cylinder.
