T9-CV Total Containment Unloader

System OVerview

Spiroflow’s T9-CV bulk bag unloader is designed specifically for handling materials that require complete containment to avoid air contamination during the unloading process. This system is ideally suited for safely unloading volatile, hazardous, or explosive contents from bulk bags.

To achieve complete material containment, the T9-CV is designed with a pneumatically actuated outlet spout clamp, with inflatable seal. Sealing the outlet spout of the bag to the downstream unloading equipment. Dual switches and a safety door interlock require operators hands to be away from the pneumatic clamp while it is in motion.

Furthermore, the T9-CV accommodates super sacks of varying sizes with its adjustable height feature.

HOW IT WORKS & BENEFITS

The T9-CV Bulk Bag Unloader is crafted to fully contain hazardous, explosive, or toxic materials. The design allows for unloading based on either volume or weight, and it can be equipped with a built-in bag hoist. Here are the core things you need to know about this model.

BASE FRAMEWORK

The base framework is engineered to support the full weight of a super sack, constructed our of 3″ square tubing. The structure features a fully welded design, and incorporates a support dish that can fit any bottom-spout bulk bag. The bag’s spout extends through the center of the dish for easy access. The rubber membrane dust seal creates an extra seal against the bottom edges of the bulk bag, ensuring a dust-free operation.

CONTAINMENT ENCLOSURE

The containment enclosure features a hinged access door equipped with polycarbonate panels for viewing. The liner clamp and downspout are contained within the enclosure. A 4-inch (100 mm) dust extraction outlet is installed at the back of the housing, for easy connection to a dust extraction setup.

OUTLET CLAMP & DOWNSPOUT

Located within the containment enclosure, the OUTLET CLAMP & DOWNSPOUT system includes a pneumatically actuated stainless steel clamp with a pneumatic seal and a stationary downspout. This setup enables the secure fastening of the bulk bag outlet spout to the downspout. Operated pneumatically, the clamp is designed to retract and connect with the clean bag spout.

The movement of the clamp is controlled by a dual-button control box, measuring 5 inches (125 mm) in width, which is positioned at the front center of the unit, just beneath the containment enclosure. Requiring the door to be shut, and both buttons depressed to actuate the clamp. Protecting operators from any potential pinch points.

PROCESS STEPS

The Bag Lifting Frame is attached to the bulk bag of material.
An operator uses a forklift to lift the bulk bag over the unloader.
The lifting frame with the bulk bag is then set onto the side tensioning frame.
The bag’s weight causes the tensioning frame springs to compress, allowing the weight of the bulk bag to settle on the support dish.
Once the bag is securely in place, the operator accesses the bulk bag’s outlet spout through the untie chamber.
The operator proceeds to pull down the outlet spout, then engage the spout closure bars to prevent flow of material during untying.
The operator wraps the outlet spout and liner (if applicable) around the downspout.
Next, the operator engages the dual safety switches, lowering the retaining ring around the bag’s outlet spout and onto the downspout.
With the retaining ring fully engaged, an inflatable ring expands to create a secure, dust-proof seal.
Finally, the operator closes the untie chamber and opens the spout closure bars to initiate the discharge of material from the bulk bag.
