New generation bulk bag discharger.

A new generation Bulk Bag Discharger from Flexicon (Europe) Ltd has recently been launched. The innovative design increases operator safety by eliminating dust during untying, discharging, retying, collapse and removal of bulk bags while achieving complete discharge with greater efficiency.

Central to the new design is a bulk bag/hopper interface consisting of a manual Spout-Lock[TM] clamp ring positioned above a pneumatically actuated Tele-Tube[TM] telescoping tube. Together, the devices enable an operator to make a quick, dust-tight connection between the bag spout and hopper, and to 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 bag spout and clamp ring allows full-open discharge from the bag, often eliminating the need for iris valves commonly employed to reduce the escape of dust by reducing the initially high rate of flow from the bag.

For applications requiring retying of partially empty bags, the company also offers a new Power-Cincher[TM] pneumatically actuated flow control valve. Unlike opposing bars that pinch the spout from two sides, the new valve contains a series of curved, articulated stainless steel rods that cinch the spout from two sides, the new valve contains a series of curved, articulated stainless steel rods that cinch the spout concentrically on a horizontal axis for easy tie off and vertically in a light zigzag pattern to prevent leakage of fine powders.
