Vorrichtung zur Vor-Ort-Entsorgung von Hygienemüll, insbesondere von Inkontinenz-Artikeln und Verfahren hierfür

摘要

On-site disposal unit for hygiene e.g. incontinence waste of fabric fleece, absorbent cellulose layer with embedded gel or absorbent granulate, outer plastics cover and hook/adhesive strip, rubber band etc. closure-retainer, has stationary drum, inlets for dosed washing and hygiene liquids and powder or liquid for treating superabsorber, bottom outlet for liquid, vertical rotary disk cutter, transport and compressing screws, solids collector and programmed control system. On-site disposal unit for hygiene waste, especially incontinence articles, of fabric fleece, absorbent cellulose layer with embedded gel or absorbent granulate, outer plastics cover on one side and hook/adhesive strips, rubber bands etc. closure-retainer, has means of reducing waste to small pieces mechanically and (partial) dissolution in washing liquid, separating residue from this liquid, passing liquid to drain and drying and separate disposal of residue. The novel features are that the unit (10) has a housing (11) comprising a stationary drum container (20) with horizontal middle axis, a filling port (25) for the waste; and separate inlets (28, 29, 129) for doses of (a) washing liquid, (b) hygiene liquid for suppressing odors and disinfection and (c) chemicals in powder or liquid form for treating the superabsorber, e.g. solids from plastics or superabsorbing polymer products or gel particles in the waste, especially diapers; an integrated outlet (50) near the bottom, preferably a screw conveyor (65) for removing crushed waste interspersed with washing liquid; a rotary vertical disk cutter (30) on one side in the drum; a compressing screw (60) with varying pitch and web thickness, in tubular housing (61), at the bottom, taking waste from the screw conveyor; a shear sieve plate (70) for separating solids from wash liquid; a functional unit preventing the compressing screw and sieve plate becoming blocked; pump (81) for discharging wash liquid to drain (85); collector (95) for compressed and crushed solids in top of housing; and programmed system for controlling feed stream dosing pumps (28', 29', 129'), cutter and compressor drives (35, 66). The pumps are controlled by this system or a freely programmable unit.
