Aufgabe der vorliegenden Erfindung ist es, eine kompakte Zerkleinerungsanlage für medizinische Abfälle zu schaffen, mit der die Feststoffe in ein hohlraumarmes Gemisch unter weitestgehender Verhinderung von Staubaustritt in die Atmosphäre überführt werden und bei der das Auswechseln der Gefäße vereinfacht ist.The object of the present invention is to provide a compact shredder for medical waste, with which the solids are transferred into a low-void mixture with the greatest possible prevention of dust escaping into the atmosphere and with which the exchange of the vessels is simplified.
Die Aufgagbe wird erfindungsgemäß durch die im Patentanspruch 1 angegebenen Merkmale gelöst. Bevorzugte Weiterbildungen der Erfindung sind den Ansprüchen 2 und 3 zu entnehmen.The task is solved according to the invention by the features specified in
Die erfindungsgemäße Lösung besteht im wesentlichen darin, daß in einem zusammenhängenden, jedoch aus mehreren Abschnitten bestegenden Gehäuse in seinem oberen Bereich ein Zerkleinerer mit einem anschliessenden Gleitschacht für die Führung des zerkleinerte Gutes in einen Separator angeordnet ist, wobei der Separator zur Trennung der Flüssigkeit und der Feststoffe vorgesehen ist und eine Lagerung am Boden des Gehäuses sowie je einem Auslauf für die Flüssigkeit und Feststoffe aufweist, und das Gehäuse durch eine Ständer in einer das Auswechseln der Abfallgefäße ermöglichenden Höhe fixiert ist.The solution according to the invention essentially consists in that a shredder with a subsequent slide shaft for guiding the shredded material into a separator is arranged in a coherent, but consisting of several sections housing in its upper region, the separator being provided for separating the liquid and the solids and being stored on the floor of the housing and each have an outlet for the liquid and solids, and the housing is fixed by a stand at a height which enables the replacement of the waste containers.
Das so aufbereitete Abfallgut kann - in der Regel, d.h. soweit es nicht infektiös ist -, durch die Hausmüllbeseitigung aufgenommen werden, wobei allerdings durch nachfolgende Verfahren eine weitere Volumenreduktion erreicht werden kann. Hierbei ist insbesondere an eine pyrolytische Nachbehandlung zu denken.The waste material prepared in this way can - as a rule, ie insofar as it is not infectious - be taken up by household waste disposal, although a further reduction in volume can be achieved by the following processes. A pyrolytic aftertreatment should be considered here in particular.
Das Antriebssystem treibt also mit einer durchgehend geführten Welle einen horizontal gegliederten Zweiwellen-Zwangszerkleinerer und einen senkrecht hierzu angetriebenen zentrifugenartig konzipierten Separator in einem Gehäuse an. Des weiteren ist, fluchtend mit der Lagerung des Separatorbodens im Gehäuseboden, eine für die mehrzahlige Aufstellung von Flüssigkeits- und Feststoffgefäßen angeordnete Drehscheibe vorgesehen, die nach dem Verfüllen durch ein Ausschwenken der Gefäße die Durchführung jweils eines Verschlusses, z. B. eines Schweißverschlusses, ermöglicht.The drive system uses a continuously guided shaft to drive a horizontally structured twin-shaft shredder and a centrifuge-type separator that is driven perpendicular to it in a housing. Furthermore, in alignment with the storage of the separator base in the housing base, a turntable arranged for the multiple installation of liquid and solid vessels is provided, which after filling by swiveling out of the vessels sometimes carries out a closure, e.g. B. a welded closure.
Zum Separator ist festzustellen, daß dieser einen topfartig noch oben gezogenen Rand ausweist und dem Boden konzentrisch ein kegelstumpfförmiges Sieb verbunden ist, in das der Gleitschacht einmündet und in dem, zur inneren Siebfläche des Siebes gerichtet, ein die Feststoffschicht abhebender Schaber angeschlossen ist, der zu einem stationär im geneigten Gehäuseboden vorgesehenen ersten Auslaß für die Feststoffe gerichtet ist und der periphere Bereich des Separatorbodens ein Siebteil bildet, in das der im geneigten Gehäuseboden vorgesehene zweite Auslauf für die Flüssigkeit einmündet.Regarding the separator, it should be noted that this has a pot-like edge still drawn upwards and a truncated cone-shaped sieve is concentrically connected to the bottom, into which the slide shaft opens and in which, directed towards the inner sieve surface of the sieve, a scraper lifting off the solid layer is connected a stationary first outlet for the solids provided in the inclined housing base and the peripheral region of the separator base forms a sieve part into which the second outlet for the liquid provided in the inclined housing base opens.
Abschließend wird noch vorgeschlagen, daß zur Unterdrückung der Staubentwicklung und zur Desinfektion im Bereich des Zerkleinerers, einleitend in den Separator, eine Vorrichtung zur Oberflächenbehandlung des zerkleinerten Gutes vorgesehen ist, die eine sichere Lagerung des so aufbereiteten medizinischen Abfalls als Hausmüll zuläßt.Finally, it is proposed that a device for surface treatment of the shredded material is provided to suppress the development of dust and for disinfection in the area of the shredder, leading into the separator, which device permits safe storage of the medical waste thus processed as domestic waste.
