Abstract
The waste compactor comprises a housing having an inclined wall in the upper part thereof. A motor on the upper wall drives a helical screw on the lower side of the inclined wall which converges conically downwardly with a decreasing pitch. A lower hopper extending downwardly from the inclined wall below the helical screw forms a funnel and is opened above to an inlet area. The inlet area receives waste material to be compacted, which material descends into the area of the helical screw. A lower more narrow end of the helical screw is located in a conduit which is slightly wider than the lower end of the helical screw and converges downwardly to a constriction at its lower end. Waste material is compacted by downward movement under the action of the helical screw and by being forced through the conduit. The lower hopper has drainage holes through which liquid can drain, by gravity, and a collector is positioned to collect the liquid passing through the drainage holes.
