ABSTRACT:
A filter cleaning apparatus for removing dust and debris from a stationary filter having a dust and debris collecting surface. The apparatus includes a longitudinally extending duct having a lengthwise slot formed therein. A belt in the duct extends across the slot whereby the duct and the belt together define a plenum. The belt has an opening formed therein adjacent the slot and in fluid communication with the plenum. The belt is mounted for movement along the slot such that the opening may be repositioned along the length of the slot. A nozzle is mounted on the belt for movement therewith and extends outwardly from the belt. The nozzle has an inlet distal from the belt. The inlet has a width substantially transverse to the length of the slot which is greater than a corresponding width of the opening in the belt. The inlet is in fluid communication with the opening and thereby the plenum. The apparatus further includes a belt driver for moving the belt along the slot.
