  • Patent number: 9555415
    Abstract: A system and method for processing solid waste disposal includes a hydrolyzer (80) and an injection assembly (30) for transferring waste to the hydrolyzer (80). The injection assembly (30) includes a sleeve (40), in which waste is compressed with a ram (37), and a movable gate (52), which opens to allow the compressed waste (68) to exit the sleeve (40) and enter the hydrolyzer (80). The hydrolyzer (80) includes a pressure vessel (84), a rotating shaft (108) contained within the vessel (84), and agitates attached to the shaft for moving and processing the material through the hydrolyzer (80).

  • Patent number: 8684171
    Abstract: A modular conveyor apparatus includes a plurality of substantially identical conveyor segments. Each conveyor segment has a pair of laterally spaced protrusions or hooks extending from one end thereof. Each conveyor segment has a plurality of spaced openings or slots along at least one of its side walls, so that two like conveyor segments can be connected together perpendicularly with the hooks of a first segment received in the side wall slots of a second segment. Thus the perpendicular connection between two conveyor segments may be made at any selected one of a plurality of locations along the length of each conveyor. Provision may also be made for end to end connection of the conveyor segments.

  • Publication number: 20080048059
    Abstract: A system for processing waste on a continuous basis comprises an infeed assembly, a vessel held at a non-ambient pressure and/or temperature, and an outfeed assembly. The infeed assembly includes: a sleeve where waste is delivered; a gate construction that moves between an open and a closed position; and a ram that moves within the sleeve to compress waste when the gate construction is in the closed position and to push the compressed waste into the vessel, where it is metamorphically processed, when the gate construction is in the open position. The processed material moves from the vessel to the outfeed assembly, which includes a compaction chamber, a ram that moves within the compaction chamber, and a cutter assembly. Waste is compacted in the compaction chamber by the ram, cut by the cutter assembly, and delivered as a compacted block to an environment having an ambient pressure and/or temperature.
