ABSTRACT:
A vacuum cleaning machine for cleaning and removing industrial wastes, including hazardous waste products, mounted to the chassis of a truck having a collection tank thereon, including a flexible boom coupled to the collection tank and projecting forwardly, with a driver-actuable collection nozzle positioned in front of the truck. An air circulation system, including a blower, is used to draw material through the suction tubes into the collection tank, and a vortex separator removes particulate matter and wet residue from the suction air stream. The air circulation system includes a filter bag housing for removing further particulate matter from the suction air stream, and this is followed by a safety filter for removing the finest particulate matter from the suction air stream. The air circulation system includes a residue feedback loop for returning particulate matter from the bag filter back into the collection tank, and further includes an air conveying system for removing collected material from the tank, wherein the tank may be internally pressurized to assist in removal of the material from the tank.
