Abstract
An apparatus and method of reclaiming particles of powder material from a powder spray system (100) having an inlet passageway (190) of a collection subsystem (104) in fluid communication with an interior of a spray booth (108). An airflow conduit (250) extends between a trough (140) located under a conveyor belt (130) which in turn is located below the spray booth (108) and the inlet passageway (190) of the collection subsystem (104). Airflow through the airflow conduit (250) is augmented by a compressed air injector (280) disposed in the airflow conduit (250) and oriented so that it ejects compressed air in the direction of the inlet passageway (190). In this manner, particulate matter (overspray) settling in the trough (140) becomes entrained in an airstream (252) flowing into the collection subsystem (104). The collection subsystem (104) suitably includes a cyclone separator (170) and a filter stack (200).
