Abstract
An apparatus for removing liquid from a composite mixture of liquid and solids comprises a hopper mounted atop a compactor ram assembly. A snout section and an extruder section are mounted axial to the compactor ram assembly. A hydraulically-operated ram compresses wet material into the snout and extruder sections. Under pressure from the ram, liquid in the waste material escapes from drainage holes in the snout section top, bottom, and sides, and the extruder section top, bottom, and sides. A platen, pivotally mounted to the extruder top plate near the exit of the device and biased with a constant pressure, controls the back pressure in the extruder and snout sections. The apparatus has an extruder section and snout section of the same constant cross section and coaxial with each other. In a second embodiment of the apparatus, certain of the walls may diverge to further facilitate access to the first platen through the exit opening.
