Discharger Dust Hood Contains Bag Spout Leaks and Spills

Flexicon1118

A new Dust Hood for Flexicon Bulk Bag Dischargers contains spillage and dust that can escape through seams in the bag and folds in the spout. The six-sided enclosure seats against the rim of a hopper or flange of downstream equipment and is equipped with an exhaust port for dust collection and a hinged door with inspection window.

The top of the enclosure contains a circular opening that allows passage of the bag spout to the equipment connection point. The flat bottom of the enclosure supports a Tele-Tube telescoping tube that pneumatically raises a Spout-Lock clamp ring which connects the clean side of the spout to the clean side of the equipment.

Allowing the telescoping tube to descend under its own weight maintains constant downward tension on the spout as the bag empties and elongates, as Flow-Flexer bag activators raise and lower opposite bottom edges of the bag at timed intervals to loosen compacted materials, promoting material flow and complete discharge from the bag.

The enclosure contains incidental leakage of fine powders from seams in the bag, as well as material released from bag spout folds during connection and disconnection activities. Associated dust is vented through the sidewall-mounted port to an optional Bag-Vac dust collector or plant bag house, preventing contamination of the environment.
