ABSTRACT:
An industrial vacuum loader comprises an enclosed hopper into which particulate matter is drawn through a loading hose. The hopper is connected by a suction hose to the lower intake port of a bag house and the upper outlet port of the bag house is connected by a transformation hose to the suction port of an engine-driven positive displacement rotary blower. The bag house comprises an upper chamber containing filtration bags and a lower dust collection chamber in which dust filtered from dust-laden air passing through the bag house is collected. Means are provided to remove the collected dust from the dust collection chamber before the accumulation thereof adversely effects filtration capacity and comprises gates for selectively closing off the dust collection chamber from the upper chamber at a location below the inlet port of the bag house so as to isolate the dust collection chamber from the blower and enable build-up of substantially atmospheric rather than low pressure in the dust collection chamber and a dust duct for connecting the closed-off dust collection chamber to the enclosed hopper whereby the collected dust is sucked into the hopper as a result of the pressure differential between the dust collection chamber and the hopper.
