Abstract
A rotary disc filter device comprises a rotary drum and a plurality of disc-shaped filter members secured about the drum. Each disc-shaped filter member has a filtering material disposed on the outside thereof. A guide bar extends longitudinally across the disc-shaped filter members and has a movable carriage mounted thereon. One or more nozzles are operatively connected to the carriage for delivering cleaning fluid onto the filtering materials. The guide bar is rotates between a cleaning position and an adjustment position. 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. When the guide bar is in the adjustment position, the carriage is movable along the guide bar without interference from the disc-shaped filter members.
