ABSTRACT:
A system including apparatus for automatically and continuously, or intermittently, feeding disposal material such as highly combustible waste plastic in containers such as 55 gallon steel drums or in packages such as 30 gallon sizes into a rotary kiln or any other appropriate receiver. Highly combustible or explosive materials must be placed carefully into a rotary kiln or other type of combustible disposal equipment because of the likelihood of explosion or blow back when the material reaches the heat. Such material contained in packages of 55 gallon steel drums or in bales or disposable cartons is delivered by conveyor to a grid for raising same and in clamping means which holds the reclaimable drum and tilts same through an openable closure into the furnace or incinerator, dumps the container and returns it to reclaimable position to be moved on out another conveyor system. The system comprises basically four components, some of which may be eliminated or substituted: (1) four roller conveyors (2) a dumping grid (3) a clamping assembly (4) a ram cylinder (5) a feeding grid (optional) (6) an airlock housing, together with suitable electrical and hydraulic control devices. The motor driven conveyors deliver either the drums or self-contained packages to the clamping assembly whereat by automatic operation of the electrical control system the drum or pack is either clamped and dumped or pushed into the furnace and if it is to be clamped and dumped and reclaimed the drum is delivered back down the conveyor system. The operator is at a remote point and may at any time overpower the system by electrical control and buttons to interrupt the process or otherwise control the outcome.
