ABSTRACT:
A rotary cartridge filler for the containerization of hazardous waste in a controlled environment, comprising an upper die module for receiving volumes of shredded waste and a lower canister module for receiving empty containers to be charged with waste from the upper module. The upper and lower modules are axially aligned and separated by a wall containing an opening for the transfer of waste from the upper module to the lower module. Both modules are mounted on a turret which rotates the modules about their axes. The upper and lower modules each contain six chambers uniformly spaced around the outer perimeter of the module and vertically aligned. In a first station, a canister enters a chamber in the lower module, and the modules are then rotated to a second station where both the upper and lower modules are purged with nitrogen. The modules are then rotated to a third station where the upper module is filled with a volume of shredded material before being rotated to a fourth station where the material is discharged to the canister in the lower module by a discharge cylinder located above the upper module. The modules are then rotated to a fifth station where the air in both modules is evacuated before being rotated to a sixth station where the filled canister is removed from the lower module.
