The new bulk bag discharger from Queensland-based Flexicon includes an enclosure to contain errant dust escaping through the seams or fabric of bulk bags when working with unlined bags.
The Bulk-Out Model BFC discharger has white polymer panels enclosing the sides, rear, and top of the frame, while clear panels on four hinged access doors allow monitoring of the discharging process.
A port on the rear panel allows venting of the enclosure to a centralised dust collection system.
Intended for applications in which trace amounts of dust can't be tolerated or when dusty materials leak through the bag itself, the enclosure works in concert with the discharger’s dust-tight bag spout interface and expands the ability of the discharger to contain dust from all areas of the bag.
To maintain dust control at the bag spout, a manual Spout-Lock clamp ring positioned on top of a pneumatically actuated Tele-Tube telescoping tube enables an operator to make a quick, dust-tight connection between the bag spout and hopper, and automatically elongate the bag as it empties to promote flow and evacuation.
The telescoping tube raises the clamp ring assembly that seals the clean side of the bag spout to the clean side of the telescoping tube, then lowers until the bag spout is pulled taut. Once the spout is untied, the telescoping assembly exerts continual downward tension on the spout, elongating the bag as it empties.
The high-integrity, dust-tight seal between the bag spout and clamp ring allows full-open discharge from the bag without dusting.
