Drum dumper discharges bulk material dust-free through slide gate valve
September 21, 2009
The drum dumper seals drums against a discharge cone, tips the drum, mates the cone against a gasketted connection, and discharges bulk material dust-free through a slide gate valve. The dumper accommodates drums from 30 to 55 gallons. The drum platform is raised by a single hydraulic cylinder, creating a dust-tight seal between the rim of a drum and the underside of the discharge cone. A second hydraulic cylinder tips the platform-hood assembly and drum, stopping at dump angles of 45, 60 or 90 degrees with a motion-dampening feature. The vertically-oriented cone mates with a gasketted inlet port fitted to the lid of an optional hopper with integral flexible screw conveyor or pneumatic pick-up adapter, or to existing process equipment. A pneumatically-actuated slide gate valve prevents material flow until the discharge cone has been properly seated in the gasketted-receiving ring. The drum dumper is available constructed of mild steel with durable industrial finishes, with material contact surfaces of stainless steel, or in all-stainless steel finished to food, dairy, pharmaceutical or industrial standards.
