This drum dumper is dust tight

| By Chemical Engineering



A new Tip-Tite Mobile Drum Dumper (photo) allows dust-free transfer of bulk materials from drums into process equipment and storage vessels. It is mounted on a mobile frame with quick-action floor jacks for stable operation anywhere in the plant. A hydraulic cylinder raises the drum carriage which seals the drum rim against a discharge cone, after which a second hydraulic cylinder tips the carriage-hood assembly and drum, stopping at a predetermined dump angle of either 45, 60 or 90 deg with a motion-dampening feature. As the assembly approaches its fully-tipped position, the outlet of the discharge cone mates with a gasketed receiving-ring inlet fitted to existing process equipment or to the lid of an optional hopper with integral pneumatic, tubular cable or flexible screw conveyor, creating a dust-tight seal. Once the discharge cone is seated against the gasket, a pneumatically-actuated slide gate valve opens, allowing material to enter the receiving vessel. The unit accommodates drums from 30 to 55 gal, weighing up to 750 lb. — Flexicon Corp., Bethlehem, Pa.
