Flexicon has designed a system to prevent dust escaping during the in-line untying and discharging of bulk bags with ingredients that feed on to pneumatic conveying equipment.
The BFF Series bulk bag discharger has a two section bag-to-conveyor interface. The uppermost section contains a Spout-Lock clam ring positioned above a pneumatically actuated Tele-Tube telescoping tube, allowing dust-tight connections between the bag spout and the hopper, as well as automatic tensioning of the bag as it empties to promote flow and evacuation.
The lower section comprises a small surge hopper that directs material into a pneumatic pick-up adapter with four conveying line connections.
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 dust-tight seal between the bag spout and clamp ring allows full-open discharge from bag spouts of all popular diameters, eliminating the need for iris valves commonly employed to lessen dust escape with bag spouts hanging loosely in hopper intake chutes.
The system is vented to an optional Bag-Vac dust collection device that collapses empty bags prior to retying and disconnection, eliminating dust emitted during manual flattening of empty bags.
The unit is constructed in carbon steel with a durable industrial finish or stainless steel finished to food grade standards.
