ABSTRACT:
A bag type air cleaning apparatus is described for collecting particulate sediment from a source of pressurized air. The apparatus is adapted for connection to the pressurized air source and receives the pressurized air within a cylindrical plenum. A plurality of upright pervious bags are openly associated with the plenum for receiving the pressurized air. The air and particulate sediment is forced upwardly into the bags and against the bag interior surfaces where the sediment will collect as the air escapes through the pervious material. The bags are mounted on upright frames that are collapsible for storage purposes. A sliding duct is provided in communication with a blower mechanism in order to successively clean the inside surfaces of the bags. The sliding duct includes a manifold that comes into contact with successive openings of the bags while being pivoted about within the plenum. The manifold is connected to the blower mechanism which produces a suction force to reverse the pressure within the successive bags. The sediment is thereby pulled from the inside walls of the bags and is delivered through the sliding duct to a discharge. In addition, sediment will settle on the bottom or floor of the plenum. This sediment is gathered and delivered by an auger mechanism to the same discharge. A biased valve is associated with the auger to close and open alternately in response to outward pressure produced by the sediment being forced outwardly by the auger. Thus the sediment received from the sliding duct and from the auger is passed through the same discharge and is disposed of by the same blower mechanism.
