Appl. No.:
8/735004

Abstract:
An enclosed abrasive blasting apparatus for a ship hull or other working surface comprises a movable and adjustable boom and an enclosed operator containment mounted on the end of the boom. The containment has a top, sides, back, bottom, and an adjustable angle open front with a peripheral gum rubber seal that is placed against the working surface. The outlet nozzle for the abrasive blasting system is positioned within the containment where the operator directs the abrasive stream against the working surface. A waste collection system creates a negative pressure in the containment that seals the containment against the working surface, while at the same time directing an airflow stream from an inlet in the top of the containment downwardly across the working surface, entraining waste particles proximate to the working surface into the airflow stream, and further directs the waste particles to a sealed collection container below the enclosure. The heavy abrasive particles fall by gravity and settle out in the collection container for re-use while the lighter dust and waste particles are drawn off and separated in a dust collector operated by a centrifugal vacuum fan.
