Apparatus for spray shower maintenance |
摘要 |
Screen cleaning showers for a sludge dewatering rotary screen thickener are kept open and effective by periodically rotating a steel wire brush positioned coaxially within the cleaning shower manifold. Shower nozzles are set into the manifold to assure full mechanical wiping of a nozzle interior surface by the axially rotating brush bristles. Brush rotation is motor driven. An automatic controller periodically and simultaneously rotates the nozzle cleaning brush and opens a normally closed solenoid valve in the shower manifold drain line.
