BULK BAG DISCHARGERS
Total Dust Containment
Sealed system prevents dust throughout the entire discharging process, from untying of bag spout to collapsing and retying of empty bags
The high integrity connection between the bag outlet spout and the discharger creates a sealed system that prevents the escape of dust throughout the entire discharging process, from untying of bag spouts to retying of partially empty bags to collapsing and retying of empty bags.
Patented SPOUT-LOCK® clamp ring creates high-integrity sealed connection
The SPOUT-LOCK® clamp ring
creates a high-integrity sealed connection between the clean side of the bag spout and the clean side of the TELE-TUBE® telescoping tube.
Once connected to the bag spout, the drawstring can be released, allowing material to fall freely into the hopper rapidly and free of dust.
The positive connection can eliminate the need for flow control valves employed to prevent uncontrolled bursts of material from the bag and dust into the plant environment.
Flow control valves are, therefore, only required for retying spouts of partially empty bags.
BAG-VAC® dust collector collapses empty bag prior to tie-off
The high integrity connection between bag outlet spout and discharger creates a sealed system that can be vented through a filter sock, to a central dust collection system, or to an optional BAG-VAC® dust collector (patent pending). Actuating the BAG-VAC® dust collector creates negative pressure within the sealed system to collapse empty bags prior to retying, eliminating dust commonly emitted when bags are flattened manually. In addition, the BAG-VAC® dust collector vacuums any particles trapped in spout creases during disconnect, eliminating the need for awkward access ports.
Double wall TELE-TUBE® telescoping tube with BAG-VAC® dust collector provides double protection against spillage
Where absolute spillage containment is essential, this optional double wall version (shown) of the TELE-TUBE® telescoping tube draws errant particles into the dust collector through an annular gap that encircles the bag spout seal.
Dust Containment Enclosure Contains Bag Spout Leaks and Spills
The Dust Containment Enclosure 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 six-sided enclosure contains a circular opening that allows passage of the bag spout to the equipment connection point, while the flat bottom supports the bag/spout interface.
Shown is a TELE-TUBE® telescoping tube that pneumatically raises a SPOUT-LOCK® clamp ring which makes a secure, dust-free connection between the clean side of the spout and the clean side of the equipment. Also available is an iris valve bag/spout interface for applications in which dust containment is not a concern.
