Description

Die Erfindung betrifft eine medizinische Ab­fallzerkleinerungsanlage.The invention relates to a medical waste crushing plant.

Die Entsorgung des medizinischen Abfalles ist im allgemeinen darauf ausgerichtet, daß dieser, sofern er nicht strahlende oder nicht schnell abbauende, stark toxische oder infizierende Substanzen enthält, durch die Hausmüllbeseiti­gung mit aufgenommen werden sollte.The disposal of medical waste is generally geared towards the fact that, if it does not contain radiating or rapidly degrading, highly toxic or infectious substances, it should be taken up with the household waste disposal.

Es ist bekannt, daß bei den praktizierenden Ärzten - sowohl in der Zahn- als auch in der Humanmedizin - sehr viel Abfall aus verschiede­nen Stoffen, z. B. in Form von Einwegspritzen, Kanülen, Verbandstoffen, Gummihandschuhen usw. anfällt. Die Entsorgung dieses Abfalls sollte sowohl die Trennung der Flüssig- und Feststoffe als auch die Kompaktierung beinhalten, wobei allerdings die Problematik als solche ernster geworden ist. Denkt man beispielsweise an die wachsende Zahl aidskranker Patienten und an die Tatsache, daß ein behandelnder Arzt oder Zahn­arzt im Augenblick einer Wundbehandlung nicht weiß, ob eine Infektion dieser Art vorliegt, so muß dieses System als absolut unzulänglich be­trachtet werden.It is known that in the practicing doctors - both in dentistry and in human medicine - a lot of waste from different substances, e.g. B. in the form of disposable syringes, cannulas, bandages, rubber gloves, etc. The disposal of this waste should include both the separation of liquids and solids and the compaction, although the problem as such has become more serious. If one thinks, for example, of the growing number of AIDS patients and the fact that a treating doctor or dentist does not know at the moment of wound treatment whether an infection of this type is present, this system must be regarded as absolutely inadequate.

Obwohl man sich heute bereits auf Fassungsvolumen dieser Abfallkontainer zwischen 5 und 20 Ltr. be­schränkt, sollten insbesondere die Feststoff­volumina der nicht genügend schnell abbaufähigen und im wesentlichen organischen Stoffe weitgehend reduziert werden, da der momentane Raumbedarf letzt­lich die Kosten der Entsorgung, d.h. der Endlagerung, bestimmt.Although the volume of these waste containers between 5 and 20 liters is already limited today, the solids volumes in particular should not be able to be degraded quickly enough and essentially organic substances are largely reduced, since the current space requirement ultimately determines the costs of disposal, ie final storage.

Eine andere Schwierigkeit stellen Patienten mit nos­komialen Infektionserregern dar, wie Z.B. Wundinfek­tionen mit Staphylococcen, Kolibakterien usw. Gerade die letztgenannten verursachen sogenannte Schmierinfektionen und sind deshalb außerordentlich unangenehm.Another problem is presented by patients with noscomial infectious agents, such as e.g. Wound infections with staphylococci, coli bacteria, etc. The latter in particular cause so-called smear infections and are therefore extremely unpleasant.

Es ist deshalb Aufgabe dieser Erfindung, den anfallen­den Abfall nicht nur zu trennen, sondern speziell die Feststoffe durch ein manuelles Eingreifen in ein möglichst hohlraumarmes Gemisch zu überführen, wobei im Rahmen der Zerkleinerung auf weitgehende Verhin­derung von Staubaustritt in die Atmosphäre zu achten ist.It is therefore an object of this invention not only to separate the waste which arises, but in particular to convert the solids by manual intervention into a mixture which is as void of void as possible, with extensive prevention of dust escaping into the atmosphere during the comminution.

Die erfindungsgemäße Lösung dieser Aufgabe sieht vor, daß in einem zusammenhängenden, jedoch aus mehreren Abschnitten bestehenden Gehäuse in seinem oberen Bereich ein Zerkleinerer mit einem anschlies­senden Gleitschacht für die Führung des zerkleinerten 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 einen Ständer in einer das Auswechseln der Abfallgefäße ermöglichenden Höhe fixiert ist.The solution to this problem according to the invention provides that a shredder with a subsequent slide shaft for guiding the shredded material into a separator is arranged in a cohesive, but consisting of several sections in its upper region, the separator for separating the liquid and the Solids is provided and has a storage at the bottom of the housing and an outlet for the liquid and _ solids, and the housing is fixed by a stand at a height that allows 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, that is to say 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.

Für die Zerkleinerung normaler Abfälle werden Ein­wellenzerkleinerer vorgeschlagen, sofern das zu zer­kleinernde Material keine besondere Beanspruchung, d.h. Verschleiß bedingt. Für diesen wird vorgeschlagen, daß die beiden Wellen des Zwangszerkleinerers durch einen Stirnradantrieb gepaart sind, wo­bei eine aus dem Zerkleinerer austretende Welle mit einem Tellerrad versehen ist, daß ausgehend von einem rechtwinklig zu dem Tellerrad angeordneten Antriebsmotor über eine Antriebswelle und ein Kegelritzel der Antrieb für den Zwangszerkleinerer gebildet wird, und daß in Fortsetzung der Antriebswelle in der­selben Richtung ein Stirn- oder Reibrad für den Antrieb des unterhalb des Zwangszerkleine­rers mit Reib- oder Stirnkranz angeordneten Separators vorgesehen ist, der in einem abschlie­ßenden, geneigten Bogen gelagert ist. 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.Single-shaft shredders are proposed for the shredding of normal waste, provided that the material to be shredded does not cause any particular stress, ie wear. For this it is proposed that the two shafts of the forced shredder are paired by a spur gear drive, a shaft emerging from the shredder being provided with a ring gear that starts from a drive motor arranged at right angles to the ring gear via a drive shaft and a bevel pinion, the drive for the Forced shredder is formed, and that, in continuation of the drive shaft in the same direction, a front or friction wheel is provided for driving the separator arranged below the forced shredder with a friction or front ring, which is mounted in a final, inclined arc. The drive system thus drives a horizontally structured two-shaft forced shredder with a continuously guided shaft and a centrifuge-type separator, which is driven perpendicularly thereto, in one housing. Furthermore, in alignment with the storage of the separator bottom in the housing bottom, a turntable arranged for the multiple installation of liquid and solid vessels is provided, which after filling by swiveling out the vessels sometimes carries out a closure, e.g. B. a sweat 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, towards the inner sieve surface of the sieve, a scraper lifting off the solid layer is connected a stationary outlet in the inclined housing base for the solids is directed 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 also 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 allows safe storage of the medical waste thus processed as domestic waste.

Die Erfindung wird durch die beigefügte Zeichnung einer medizinischen Abfallzerkleinerungs­anlage in im wesentlichen schematischer. Dar­stellung näher erläutert.

  • Figur 1 zeigt die Gesamtansicht der Abfallzerkleinerungs­anlage einschließlich je eines Auslaufs für die Flüssigkeit und die Feststoffe.
  • Figur 2 zeigt im Grundriß die Drehscheibe für die Aufstellung der Abfallgefäße.
The invention is illustrated in an essentially schematic manner by the attached drawing of a medical waste crushing plant. Presentation explained in more detail.
  • Figure 1 shows the overall view of the waste crushing plant including an outlet for the liquid and the solids.
  • Figure 2 shows in the floor plan the turntable for the installation of the waste containers.

Die Abfallzerkleinerungsanlage 1 baut im wesentlichen in einem aus mehreren Abschnitten bestehenden Ge­häuse 2 auf. Im oberen Bereich dieses Gehäuses 2 ist ein Doppelwellenzwangszerkleinerer 3, dessen Zerkleinerungswellen 3.1 durch eine Stirnradpaarung 3.2 verbunden sind, vorgesehen. Eine der austretenden Wellen 3.3 trägt ein relativ groß gehaltenes Teller­rad 3.4 für den später weiter beschriebenen Antrieb.The waste comminution system 1 is essentially constructed in a housing 2 consisting of several sections. In the upper area of this housing 2 there is a double-shaft positive shredder 3, the shredding shafts 3.1 of which are connected by a spur gear pair 3.2. One of the emerging shafts 3.3 carries a relatively large ring gear 3.4 for the drive described later.

Das zerkleinerte Gut führt über einen Gleitschacht 4 in den Separator 5 ein, der durch einen topfartigen Rand 5.1 abgegrenzt ist. Der Separatorboden 5.2 trägt ein konzentrisch angeordnetes, kegelstumpfförmiges Sieb 5.3, wobei der verbleibende periphere Boden­bereich 5.5 ebenfalls mit einem ringförmigen Siebteil 5.4 ausgebildet ist. Das kegelstumpfförmige Sieb 5.3 übernimmt dabei die Funktion des Trennsiebes.The comminuted material leads through a slide shaft 4 into the separator 5, which is delimited by a pot-like edge 5.1. The separator bottom 5.2 carries a concentrically arranged, truncated cone-shaped sieve 5.3, the remaining peripheral bottom region 5.5 also being formed with an annular sieve part 5.4. The frustoconical sieve 5.3 takes over the function of the separating sieve.

An der nach innen gerichteten Neigung der Sieb­fläche lagern sich die Feststoffteile ab und wer­den durch einen abhebenden Schaber 4.1 von der Wandung gelöst und durch die Öffnung 5.5 im Sepa­ratorboden 5.2 in den Auslauf 2.5 für die Fest­stoffe geleitet. Die Flüssigkeit wird, zentrifugal­kraftbedingt, durch das kegelförmige Sieb 5.3 wei­ter verdrängt, an den topfartigen Rand 5.1 nieder­geschlagen und über das im Boden plan angeordnete, ringförmige Siebteil 5.4 über den Auslauf 2.4 zu dem Flüssigeitsgefäß 6.3 abgeschieden.The solid parts are deposited on the inward inclination of the sieve surface and are removed from the wall by a lifting scraper 4.1 and passed through the opening 5.5 in the separator base 5.2 into the outlet 2.5 for the solids. Due to centrifugal force, the liquid is further displaced by the conical sieve 5.3, deposited on the pot-like edge 5.1 and separated via the outlet 2.4 to the liquid vessel 6.3 via the annular sieve part 5.4 arranged flat in the bottom.

Die verwendeten Gefäße 6.3 und 6.4 sind in ihrem oberen Randbereich für die Anordnung eines Kunst­stoffschweißverschlusses entsprechend ausgebildet.The vessels 6.3 and 6.4 used are appropriately designed in their upper edge area for the arrangement of a plastic weld closure.

Auf der Anlage ist der Antriebsmotor 7 vorgesehen, der über eine Abtriebswelle 7.1 zunächst das Kegel­radritzel 7.2 für den Antrieb des Tellerrades 3.4 und in dessen Verlängerung den Antrieb des Stirn- oder Reibrades 7.3 ermöglicht. Dieses Rad 7.3 greift in einen den Separator 5 umfassenden Stirn- oder Reibkranz 8 ein. Unterhalb der Zentralen des Se­parators 5 ist eine Drehscheibe 9 für die Auf­stellung der Gefäße 6.3 und 6.4 vorgesehen, wobei auf die Beschreibung dieser Einzelheit verzichtet wird.In the system, the drive motor 7 is provided, which, via an output shaft 7.1, first enables the bevel gear pinion 7.2 for driving the ring gear 3.4 and, in its extension, the drive of the spur or friction wheel 7.3. This wheel 7.3 engages in a front or friction ring 8 comprising the separator 5. Below the centers of the separator 5, a turntable 9 is provided for the installation of the vessels 6.3 and 6.4, the description of this detail being omitted.

Durch die Beschickung mündet eine Vorrichtung 10 zur Oberflächenbehandlung der zerkleinerten Teile ein, mit dem Ziel, einmal die Staubbildung weit­gehend zu unterdrücken und die Infektionsgefahr auf eine Minimum zu reduzieren.Through the loading, a device 10 for surface treatment of the shredded parts opens, with the aim of largely suppressing the formation of dust and reducing the risk of infection to a minimum.

Ergänzend ist zu bemerken, daß das Gehäuse 2 durch den Ständer 2.1 in einem die Manipulation der Gefäße 6.3 und 6.4 ermöglichenden Abstand getragen wird und zwar durch drei Klötze 11 auf einer Arbeits­platte.In addition, it should be noted that the housing 2 is carried by the stand 2.1 at a distance which enables the manipulation of the vessels 6.3 and 6.4, namely by three blocks 11 on a worktop.
