Mobile drum dumper
Mobile drum dumper The Tip-Tite mobile drum dumper allows dust-free transfer of bulk materials from drums into process equipment and storage vessels. Ready to plug in and run, the drum dumper 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 degrees 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 gallons (114 to 208 liters) weighing up to 750 pounds (340 kg) and measuring 36 to 48 inches (91 to 122 cm) in height. (Flexicon)
