Mobile Drum Dumper with
flexible screw feeder for use in hazardous locations
BETHLEHEM , PA — A new TIP-TITE ® Mobile Drum Dumper with integral flexible screw conveyor is designed for use in hazardous locations . It allows volumetric feeding of bulk material from drums into downstream processes dust free and with minimal operator intervention . The system is mounted on a mobile frame with quick-action floor jacks for stable operation anywhere in the plant .
The hydraulic power unit used to lift , seal and tip the drums is powered pneumatically , eliminating the risk of potential sparks from electrical or other equipment that might otherwise be used to actuate the hydraulics . As an additional safeguard , the controls for the flexible screw conveyor are mounted on extended support brackets , placing them outside of the hazardous zone .
The unit accommodates drums from 30 to 55 gal ( 115 to 200 liters ) and measuring 36 to 48 in . ( 91 to 122 cm ) in height . After the drum is placed in the lifting carriage , the carriage is raised against a rubber gasket mounted inside the discharge cone , creating a dust tight seal . The entire apparatus is then tipped , with a motion-dampening feature stopping the process when the predetermined dump angle is reached .
The material exits the discharge cone and into the charging adapter of the flexible screw conveyor . Fully enclosed inside polymer or steel tubing , the inner screw of the conveyor is the only moving part contacting material , resulting in reduced maintenance and increased reliability . As the screw rotates , it self-centers within the tube , providing ample clearance between the screw and the tube wall to
