Abstract:
1. A rotary disc filter device comprising: a. a rotary drum having an inlet for receiving liquid to be filtered; b. a plurality of disc-shaped filter members secured about the drum and extending outwardly therefrom, each disc-shaped filter member being rotatable with the drum about an axis of rotation; c. each disc-shaped filter member having a filtering material disposed on the outside thereof; d. a guide bar disposed adjacent to the disc-shaped filter members and outside of the rotary drum, the guide bar extending longitudinally across the disc-shaped filter members in a direction generally parallel to the axis of rotation; e. a carriage mounted on the guide bar and movable back and forth along the guide bar; f. one or more nozzles operatively connected to the carriage for delivering cleaning fluid onto the filtering materials and cleaning the filtering materials; h. a drive for driving the carriage along the guide bar; g. a pump operatively connected to the nozzle for delivering cleaning fluid to the nozzle; i. wherein the guide bar is rotatably mounted adjacent to the disc-shaped filter members such that the guide bar rotates between a cleaning position and an adjustment position; j. wherein when the guide bar is in the cleaning position, the nozzle is disposed adjacent to one of the disc-shaped filter members such that the nozzle is positioned to deliver cleaning fluid onto the filtering material; and k. wherein when the guide bar is in the adjustment position, the carriage and the nozzle are movable along the guide bar without interference from the disc-shaped filter members.
