  • Sealed waste transfer system for vacuum blasting
    Patent number: 5591067
    Abstract: A vacuum blasting machine with a sealed waste transfer system has a collapsible sleeve that provides a containment interface between the waste chamber and the waste collection drum. The periphery of one end of the sleeve is secured around the periphery of the opening in the waste collection drum. In the transfer operation, the other end of the sleeve is pulled over the dump housing, providing an impervious containment barrier between the dump housing and the interior of the collection drum. The drum has a vent opening with a bushing to which a vent line is attached. A vent line connects the collection drum to the interior of the waste chamber via a valve.
