The centrifuge has a stationary outer housing (1), a shaft bearing (5) which is arranged on the top side of the outer housing so as to be flexible or rotatable, a shaft (4) which is rotatably received by the shaft bearing and extends into the outer housing and a centrifuge drum supported by the shaft. An inner housing (2) is arranged on the shaft bearing so as to surround the drum in a gas-tight manner and so as to be rotated together with the drum. The device for removing (11) the solid cake arranged on the drum wall is secured to the shaft bearing or to the inner housing so as to be rotatable together with the same, thereby ensuring that the solid cake can be completely removed without damaging the inner wall of the drum.

Description

Zentrifuge  centrifuge
Die vorliegende Erfindung betrifft eine Zentrifuge mit hängend angeordneter Zentrifugentrommel mit einem festen Außengehäuse, einem an der Oberseite des Außengehäuses flexi- bei bzw. verschwenkbar angeordneten Wellenlager, einer vom Wellenlager drehbar gelagerten und sich in das Außengehäuse erstreckenden Welle, einer von der Welle getragenen Zentrifugentrommel mit Einlass und Auslass, einem außerhalb des Außengehäuses angeordneten Wellenantrieb und einer Einrich- tung zum Entfernen des an der Trommelinnenwand angesammelten Feststoffkuchens . The present invention relates to a centrifugally arranged centrifuge drum with a fixed outer housing, a pivotable on the upper side of the outer housing and arranged pivotally mounted shaft bearing rotatably mounted and extending into the outer housing shaft, carried by the shaft with a centrifuge drum Inlet and outlet, a shaft drive arranged outside the outer housing and a device for removing the solids cake accumulated on the drum inner wall.
Derartige Zentrifugen sind bekannt. Sie haben den Vorteil, dass sie mit sehr hohen Drehzahlen betrieben werden können, durch pendelnde Lagerung der Zentrifugentrommel hohe auf das Lager einwirkende Kräfte vermieden und kritische Vibrationen verhindert werden können. Die die Zentrifugentrommel tragende Welle erstreckt sich dabei von oben in das feste Außengehäuse der Zentrifuge hinein und wird von einem au- ßerhalb des Außengehäuses angeordneten Antrieb angetrieben. Die flexible Anordnung des Wellenlagers wird beispielsweise dadurch erreicht, dass das Wellenlager eine Kugelkalotte besitzt, die in einer entsprechenden Lagerpfanne des Außengehäuses gelagert ist und somit entsprechende Schwenk- bzw. Pendelbewegungen der Zentrifugentrommel mit Welle ermög- licht. Such centrifuges are known. They have the advantage that they can be operated at very high speeds, by oscillating storage of the centrifuge drum high forces acting on the bearing can be avoided and critical vibrations can be prevented. The shaft carrying the centrifuge drum extends from above into the fixed outer housing of the centrifuge and is driven by a drive disposed outside the outer housing. The flexible arrangement of the shaft bearing, for example achieved in that the shaft bearing has a spherical cap, which is mounted in a corresponding bearing cup of the outer housing and thus enables appropriate pivoting or oscillating movements of the centrifuge drum with shaft light.
Zur Entfernung des nach dem Zentrifugieren an der Trommelinnenwand angesammelten Feststoffkuchens findet eine entsprechende Entfernungseinrichtung Verwendung, bei der es sich beispielsweise um eine mechanisch wirkende Einrichtung handeln kann, die entsprechende Schaber- bzw. Messervorrichtungen zum Entfernen des Kuchens besitzt. In order to remove the solid cake accumulated on the inside wall of the drum after centrifuging, a corresponding removal device is used, which may be, for example, a mechanically acting device which has corresponding scraper or knife devices for removing the cake.
Eine derartige Entfernungseinrichtung wurde bisher in der Regel am festen Außengehäuse angeordnet, um für eine stabile Lagerung zu sorgen. Diese Art der Lagerung hat jedoch den Nachteil, dass dann, wenn die Welle mit Zentrifugentrommel beim Entfernen des Feststoffkuchens eine relativ zur Zentrifugenachse verschwenkte Lagerung einnimmt, wenn die Welle beispielsweise während der Entfernung des Feststoffkuchens mit geringen Drehzahlen rotiert, keine Parallelität mehr zwischen der Welle mit Zentrifugentrommel und der Entfernungseinrichtung gegeben ist, so dass die Gefahr besteht, dass die Entfernungseinrichtung an manchen Stellen zu tief in den Feststoffkuchen einschneidet, was zu Beschädigungen führen kann, und an manchen Stellen nicht tief genug in den Kuchen eindringt, so dass Feststoffkuchenreste zurückbleiben. Weitere Probleme können bei derartigen Zentrifugen dadurch auftreten, dass Flüssigkeiten oder Gase, die im Außengehäu- se bzw. im Trommelraum enthalten sind, aus der Lagerdichtung austreten können, da diese Lagerdichtungen bei der hier beschriebenen flexiblen Pendellagerung keine absolute Dichtigkeit besitzen. Ein solcher Austritt ist unerwünscht und birgt ein gewisses Gefahrenpotential. Such a removal device has hitherto generally been arranged on the fixed outer housing in order to ensure stable storage. However, this type of storage has the disadvantage that when the shaft with centrifuge drum during removal of the solid cake occupies a pivoted relative to the centrifuge axis storage, when the shaft rotates, for example, during the removal of the solids cake at low speeds, no more parallelism between the shaft Centrifuge drum and the removal device is given, so that there is a risk that the removal device in some places cuts too deeply into the solids cake, which can lead to damage, and in some places does not penetrate deeply enough into the cake, so that remain solid cake residues. Further problems can occur in such centrifuges in that liquids or gases which are in the outer housing se or contained in the drum space can escape from the bearing seal, since these bearing seals have no absolute tightness in the case of the flexible self-aligning bearing described here. Such leakage is undesirable and carries a certain potential for danger.
Aus der US-PS 5 425 698 ist eine Zentrifuge bekannt, die die Merkmale des Oberbegriffes von Patentanspruch 1 aufweist. Bei dieser bekannten Zentrifuge vermeidet man die vorstehend geschilderten Probleme einer Schiefstellung zwischen Welle und Entfernungseinrichtung beim Entfernen des Feststoffkuchens dadurch, dass man die Welle mit Zentrifugentrommel beim Entfernen des Feststoffkuchens arretiert, so dass sich zwischen Welle und Entfernungseinrichtung eine Parallelstellung ergibt. Eine derartige Ausschaltung des Pendelvermögens der Welle wird bei niedrigen Drehzahlen, die bei der Entfernung des Feststoffkuchens Anwendung finden, als unschädlich angesehen. Zur Arretierung der Welle mit Trommel dient ein Kolben, der in der Mitte der Zentri- fugentrommel abgesenkt wird und dabei eine am oberen Ende der Trommel angeordnete Nabe umgreift und hierdurch Welle und Trommel gegen Radialbewegungen sichert bzw. axial fixiert. Bei dieser Zentrifuge ist die Entfernungseinrichtung am Gehäuse der Zentrifuge angebracht. From US-PS 5 425 698 a centrifuge is known which has the features of the preamble of claim 1. In this known centrifuge avoids the above-described problems of misalignment between the shaft and removal device when removing the solids cake in that the shaft is locked with centrifuge drum during removal of the solid cake, so that there is a parallel position between shaft and removal device. Such elimination of the pendulum power of the shaft is considered harmless at low speeds used in the removal of the solids cake. To lock the shaft with the drum, a piston is used, which is lowered in the center of the centrifuge drum and engages around a hub arranged at the upper end of the drum and thereby secures the shaft and drum against radial movements or fixes them axially. In this centrifuge, the removal device is attached to the housing of the centrifuge.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine mit hohen Drehzahlen betreibbare Zentrifuge der eingangs wiedergegebenen Art zu schaffen, die sich bei einem einfachen Aufbau durch eine hohe Gas/Flüssigkeitsdichtigkeit auszeichnet und eine besonders effiziente und rasche Entfernung des Feststoffkuchens ermöglicht. Diese Aufgabe wird erfindungsgemäß bei einer Zentrifuge der angegebenen Art dadurch gelöst, dass am Wellenlager zusammen mit diesem verschwenkbar ein die Trommel gasdicht umge- bendes Innengehäuse angeordnet ist und dass die Entfernungseinrichtung am Lager oder am Innengehäuse zusammen mit diesen verschwenkbar ist. The present invention has for its object to provide a high-speed operable centrifuge of the type reproduced above, which is characterized in a simple structure by a high gas / liquid tightness and allows a particularly efficient and rapid removal of the solids cake. This object is achieved in a centrifuge of the specified type in that at the shaft bearing together with this pivotable a gas-tight surrounding the drum inner housing is arranged and that the removal device on the bearing or on the inner housing is pivotable together with these.
Zur Lösung der vorstehend geschilderten Probleme geht die Erfindung einen anderen Weg als der geschilderte Stand der Technik. Während beim Stand der Technik die Entfernungseinrichtung am Außengehäuse der Zentrifuge angebracht ist, d.h. abhängig von Welle und Zentrifugentrommel, sieht die Erfindung eine Anbringung der Entfernungseinrichtung am Wellenlager oder an einem die Trommel gasdicht umgebenden Innengehäuse vor. Hierdurch wird erreicht, dass die Entfernungseinrichtung die Bewegungen der Welle mit Zentrifugentrommel immer mitmacht und in jedem Zustand ihre Parallelität zur Welle beibehält, d.h. zwischen Welle mit Trommel und Entfernungseinrichtung keine Relativbewegung auftritt. Hierdurch wird sichergestellt, dass in jedem Zustand, d.h. selbst bei erhöhten Drehzahlen der Zentrifugentrommel, eine einwandfreie Entfernung des Feststoffkuchens stattfinden kann, ohne hierdurch die Trommelinnenwand zu beschädigen oder keine vollständige Entfernung des Feststoffkuchens zu bewirken. Die Entfernungseinrichtung ist erfindungsgemäß entweder am Wellenlager selbst oder am erfindungsgemäß zusätzlich vorgesehenen Innengehäuse angebracht. Diese Teile führen die Schwenk- bzw. Pendelbewegung der Welle und Trom- mel mit durch. Das zusätzlich erfindungsgemäß vorgesehene Innengehäuse, das die Trommel gasdicht umgibt, verhindert den Austritt von Flüssigkeiten oder (schädlichen) Gasen aus der Trommel und stellt zusätzlich zur Lagerdichtung am Außengehäuse eine weitere Barriere zum Austritt von unerwünschten Substanzen dar. Das Innengehäuse kann somit als „Fanggehäuse" bezeichnet, werden. Es folgt zwangsweise der Pendelbewegung des Rotors . To solve the problems described above, the invention takes a different route than the described prior art. While in the prior art, the removal device is mounted on the outer housing of the centrifuge, ie depending on the shaft and the centrifuge drum, the invention provides an attachment of the removal device on the shaft bearing or on a drum surrounding the drum inner housing. This ensures that the removal device always participates in the movements of the shaft with the centrifuge drum and maintains their parallelism to the shaft in each state, ie no relative movement occurs between shaft with drum and removal device. This ensures that in each state, ie even at increased speeds of the centrifuge drum, a proper removal of the solid cake can take place without damaging the inner wall of the drum or causing complete removal of the solid cake. The removal device according to the invention is mounted either on the shaft bearing itself or on the invention additionally provided inner housing. These parts carry out the swiveling or oscillating movement of the shaft and drum. The additionally inventively provided inner housing, which surrounds the drum in a gastight manner, prevents the escape of liquids or (harmful) gases from the drum and is in addition to the bearing seal on the outer housing another barrier to the escape of undesirable substances, the inner housing can thus be referred to as "catching enclosure." It follows forcibly the pendulum motion of the rotor.
Um keine großen Massen mitbewegen zu müssen, ist das Innengehäuse vorzugsweise leicht ausgebildet. Es versteht sich, dass es eine entsprechende Festigkeit besitzen muss, wenn die Entfernungseinrichtung am Innengehäuse befestigt ist. Ist die Befestigungseinrichtung am Wellenlager montiert, kann das Innengehäuse eine geringere Festigkeit aufweisen. So ist das Innengehäuse bei einer ersten Ausführungsform zumindest teilweise als starres Gehäuse ausgebildet. Beispielsweise kann eine Ausführungsform Verwendung finden, bei der der Deckel des Gehäuses starr ausgebildet ist, um an diesem die Entfernungseinrichtung zu befestigen, während der restliche Teil des Gehäuses flexibel ausgebildet ist. Bei einer anderen Ausführungsform ist das Innengehäuse als flexibles Gehäuse (zumindest teilweise), insbesondere als Faltenbalg, ausgebildet. Die Entfernungseinrichtung kann insbesondere an der Oberseite oder aber auch an der Unterseite des Gehäuses befestigt sein. Bei einer Befestigung an der Unterseite ist die Gehäuseunterseite entsprechend starr ausgebildet. Bei der Entfernungseinrichtung kann es sich um eine mechanische Entfernungseinrichtung mit einer Schaber/Messervor- richtung handeln. Die Entfernungseinrichtung kann jedoch auch als Redispergiereinrichtung ausgebildet sein, mittels der ein Redispergierfluid in die Zentrifugentrommel eingeführt wird, um den gebildeten Feststoffkuchen von der Trom- melinnenwand zu lösen und aus der Zentrifuge herauszuführen, und ein Zuführrohr für ein Redispergierfluid besitzen. Entsprechende Ausführungsformen sind bekannt und müssen an dieser Stelle nicht mehr im Einzelnen erläutert werden. Wesentlich ist, dass erfindungsgemäß im Wesentlichen Paralle- lität zwischen Welle und Entfernungseinrichtung, d.h.. deren Zuführrohr oder deren Trägerelement für die Schaber/Messervorrichtung, eingehalten wird. In order not to have to move large masses, the inner housing is preferably formed slightly. It is understood that it must have a corresponding strength when the removal device is attached to the inner housing. If the fastening device is mounted on the shaft bearing, the inner housing may have a lower strength. Thus, in a first embodiment, the inner housing is at least partially designed as a rigid housing. For example, an embodiment may be used in which the cover of the housing is rigidly designed to attach to the removal device, while the remaining part of the housing is flexible. In another embodiment, the inner housing as a flexible housing (at least partially), in particular as a bellows, is formed. The removal device can be fastened in particular on the upper side or also on the underside of the housing. When attached to the bottom of the housing bottom is designed to be rigid. The removal device may be a mechanical removal device with a scraper / knife advance. acting direction. However, the removal device can also be designed as a redispersing device, by means of which a redispersing fluid is introduced into the centrifuge drum in order to detach the solid cake formed from the drum inner wall and to lead it out of the centrifuge, and to have a redispersing fluid feed tube. Corresponding embodiments are known and need not be explained in detail at this point. It is essential that according to the invention substantially parallelism between shaft and removal device, ie. the feed tube or the carrier element for the scraper / knife device, is maintained.
Um die vorstehend erwähnte flexible bzw. schwenkbare Lage- rung der Welle mit Zentrifugentrommel zu erreichen, weist das flexible Wellenlager vorzugsweise eine Kugelkalotte auf, die in einer entsprechend ausgebildeten Lagerpfanne des Außengehäuses gelagert ist. Ferner besitzt das Wellenlager vorzugsweise eine ein Wälzlager oder ein Magnetlager für die Welle aufnehmende Lagerbuchse, die schwenkbar an der Oberseite des Außengehäuses gelagert ist, und zwar vorzugsweise mithilfe der vorstehend beschriebenen Kugelkalotte und sphärischen Lagerpfanne. Wenn die Entfernungseinrichtung am Wellenlager befestigt ist, ist sie insbesondere an der vorstehend beschriebenen Lagerbuchse des Wellenlagers montiert. Auch hiermit ist sichergestellt, dass die Entfernungseinrichtung die Wanderungsbewegungen der Welle mit Zentrifugentrommel mitmacht. Bei noch einer anderen bevorzugten Ausführungsform der Erfindung ist das Innengehäuse relativ zur Zentrifugentrommel absenkbar oder anhebbar. Hierbei weist das Innengehäuse insbesondere eine entfernbare Oberseite oder Unterseite auf. Die Absenkbarkeit oder Anhebbarkeit des Innengehäuses kann über eine geeignete kraftbetätigte Antriebseinrichtung, beispielsweise einen entsprechenden Linearantrieb, erreicht werden. Sinn und Zweck dieser Anordnung ist es, durch das Entfernen des Innengehäuses an die Zentrifugen- trommel zu gelangen, und zwar beispielsweise zu Wartungszwecken oder Reinigungszwecken. Beispielsweise wird hierzu die Oberseite (Deckel) des Innengehäuses entfernt und das Innengehäuse mithilfe der Antriebseinrichtung abgesenkt. Die Trommel ist dann zu den vorstehend angegebenen Zwecken frei zugänglich. Nach Beendigung des Wartungsvorganges wird das Innengehäuse wieder angehoben und mit seiner Oberseite verbunden . In order to achieve the abovementioned flexible or pivotable mounting of the shaft with centrifuge drum, the flexible shaft bearing preferably has a spherical cap, which is mounted in a correspondingly designed bearing cup of the outer housing. Further, the shaft bearing preferably has a rolling bearing or a magnetic bearing for the shaft receiving bushing, which is pivotally mounted on the upper side of the outer housing, preferably by means of the above-described spherical cap and spherical bearing cup. When the removal device is attached to the shaft bearing, it is in particular mounted on the bearing bushing of the shaft bearing described above. This also ensures that the removal device participates in the migration movements of the shaft with centrifuge drum. In yet another preferred embodiment of the invention, the inner housing is lowerable or raisable relative to the centrifuge drum. In this case, the inner housing in particular on a removable top or bottom. The sinkability or liftability of the inner housing can be achieved via a suitable power-operated drive device, for example a corresponding linear drive. The purpose of this arrangement is to get to the centrifuge drum by removing the inner housing, for example for maintenance or cleaning purposes. For example, for this purpose, the top (cover) of the inner housing is removed and the inner housing is lowered by means of the drive means. The drum is then freely accessible for the purposes stated above. After completion of the maintenance process, the inner housing is raised again and connected to its top.
Das Außengehäuse kann im Verhältnis zum Innengehäuse belie- big groß ausgebildet sein. Bei einer bevorzugten Ausführungsform ist das Außengehäuse der Zentrifuge als begehbarer Raum ausgebildet, was den Vorteil hat, dass die entsprechenden Teile zu Montage/Wartungs/Reinigungszwecken etc. gut zugänglich sind. The outer housing can be made arbitrarily large in relation to the inner housing. In a preferred embodiment, the outer housing of the centrifuge is designed as a walk-in space, which has the advantage that the corresponding parts for assembly / maintenance / cleaning purposes, etc. are easily accessible.
Da durch die erfindungsgemäße Anordnung eines Innengehäuses eine gute Gasdichtigkeit (gegen aus der Trommel austretende Gase) erreicht wird, können entsprechende Zusatzmaßnahmen, wie Membranen, Kompensatoren, entfallen, so dass eine ein- fache und kostengünstige Ausführungsform gewonnen wird. Die Erfindung wird nachfolgend anhand von zwei Ausführungsbeispielen in Verbindung mit der Zeichnung im Einzelnen erläutert. Es zeigen: Since a good gas-tightness (against gases emerging from the drum) is achieved by the inventive arrangement of an inner housing, corresponding additional measures, such as membranes, compensators, can be dispensed with, so that a simple and cost-effective embodiment is obtained. The invention will be explained in more detail below with reference to two exemplary embodiments in conjunction with the drawing. Show it:

Die in Figur 1 teilweise im Vertikalschnitt dargestellte Zentrifuge mit hängend angeordneter Zentrifugentrommel besitzt ein Außengehäuse 1, das beispielsweise aus Beton, Stahl etc. bestehen kann und einen großen Raum umschließt, in dem ein Innengehäuse 2 angeordnet ist, das eine Zentrifugentrommel 3 umschließt. Die Zentrifugentrommel 3 ist etwa zylindrisch ausgebildet und ist über eine Nabe mit einer Welle 4 fest verbunden. Die Welle 4 ist am Außengehäuse 1 über ein schematisch bei 5 dargestelltes Lager drehbar gelagert und erstreckt sich in das Außengehäuse 1 und das Innengehäuse 2 hinein. Sie wird von einem außerhalb des Außengehäuses angeordneten Antrieb 12 (Elektromotor) rotatorisch angetrieben. The centrifuge with suspended centrifuge drum, which is shown partially in vertical section in FIG. 1, has an outer housing 1, which can be made of concrete, steel, etc., and encloses a large space in which an inner housing 2 is arranged which encloses a centrifuge drum 3. The centrifuge drum 3 is approximately cylindrical and is fixedly connected to a shaft 4 via a hub. The shaft 4 is rotatably mounted on the outer housing 1 via a bearing schematically shown at 5 and extends into the outer housing 1 and the inner housing 2 inside. It is driven in rotation by a drive 12 (electric motor) arranged outside the outer housing.
Das Wellenlager 5 ist über eine Abdeckung 13 an der Außen-' seite des Gehäuses abgedeckt und besitzt eine Lagerbuchse 7, die sich nach oben erweitert und dort einen kugelkalot- tenförmigen Abschnitt 6 aufweist. Dieser Abschnitt ist in einer entsprechend sphärisch ausgebildeten Gelenkpfanne am fest am Außengehäuse 1 angebrachten Teil des Wellenlagers 5 flexibel gelagert. Aufgrund der sphärischen Lagerung der Welle 4 kann diese Radialbewegungen ausführen, die zu einem Verschwenken der Welle innerhalb der Gelenkpfanne des Au- ßengehäuses 1 führen. The shaft bearing 5 is covered by a cover 13 on the outer ' side of the housing and has a bearing bush 7, which widens upwards and there has a kugelkalot- tenförmigen section 6. This section is in a correspondingly spherical socket on firmly attached to the outer housing 1 mounted part of the shaft bearing 5 flexibly. Due to the spherical bearing of the shaft 4, this can perform radial movements, which lead to a pivoting of the shaft within the socket of the outer housing 1.
Innerhalb der Lagerbuchse befinden sich zwei Wälzlager (nicht gezeigt) , mit denen eine die Welle 4 umgebende Lagerhülse 16 drehbar innerhalb der Lagerbuchse 7 gelagert ist. Die Welle 4 ist daher sowohl drehbar als auch Within the bearing bush are two rolling bearings (not shown), with which a shaft 4 surrounding bearing sleeve 16 is rotatably mounted within the bearing bush 7. The shaft 4 is therefore both rotatable and
verschwenkbar gelagert. Durch Drehungen der Welle 4 wird die am unteren Wellenende befestigte Zentrifugentrommel 3 in Rotation versetzt. Das hier dargestellte Innengehäuse 2 ist als „Fanggehäuse" ausgebildet und verhindert das Austreten vor. Flüssigkeiten oder 'Gasen aus der Zentrifugentrommel 3. Das Innengehäuse 2 hat einen abnehmbaren Deckel 14 und ist im Übrigen sehr leicht ausgebildet. Es ist am Wellenlager 5, hier an der Lagerbuchse 7, befestigt und ist daher zusammen mit dempivoted. By rotation of the shaft 4, the attached at the lower end of the shaft centrifuge drum 3 is rotated. The inner housing 2 shown here is designed as a "catch housing" and prevents it from escaping from liquids or gases from the centrifuge drum 3. The inner housing 2 has a removable cover 14 and is otherwise very lightly formed the bearing bush 7, attached and is therefore together with the
Wellenlager 5 relativ zum Außengehäuse 1 verschwenkbar bzw. macht die von der Welle 4 ausgeführten Pendelbewegungen mit. Die Befestigung des Innengehäuses 2 am Wellenlager ist flüssigkeitsdicht und gasdicht ausgeführt. Shaft bearing 5 relative to the outer housing 1 pivoted or makes the running of the shaft 4 oscillations with. The attachment of the inner housing 2 on the shaft bearing is liquid-tight and gas-tight.
Zur Entfernung des sich nach dem Zentrifugiervorgang an der radialen Innenwand der Zentrifugentrommel absetzenden Feststoffkuchens dient eine Entfernungseinrichtung 9, die am Deckel 14 des Innengehäuses befestigt ist. Diese Entfer- nungseinrichtung 9 weist einen sich parallel zur Welle 4 erstreckenden Arm 10 auf, der eine Vielzahl von Schabern bzw. Messern 11 trägt, mit denen der Feststoffkuchen entfernt wird. Der Arm 10 verläuft parallel zur Welle 4 bzw. Trommel 3. Dadurch, dass die Entfernungseinrichtung 9 am Deckel 14 des Innengehäuses 2 befestigt ist und das Innen- gehäuse 2 am Wellenlager 5 befestigt ist, macht die Entfernungseinrichtung 9 sämtliche Pendelbewegungen der Welle 4 mit, so dass der Abstand zwischen Welle 4 und Arm bzw. To remove the deposited after the centrifuging at the radial inner wall of the centrifuge drum solids cake is a removal device 9, which is fixed to the cover 14 of the inner housing. This removal device 9 has an arm 10 that extends parallel to the shaft 4 and that has a multiplicity of scrapers or knives 11 carries, with which the solid cake is removed. The arm 10 runs parallel to the shaft 4 or drum 3. Because the removal device 9 is fastened to the cover 14 of the inner housing 2 and the inner housing 2 is fastened to the shaft bearing 5, the removal device 9 makes all the oscillating movements of the shaft 4, so that the distance between shaft 4 and arm or
Trommelinnenwand und Arm 10 immer konstant bleibt, selbst wenn die Welle 4 relativ zum Außengehäuse 1 eine Schräg- Stellung einnimmt. Drum inner wall and arm 10 always remains constant, even if the shaft 4 assumes a skewed position relative to the outer housing 1.
Der Feststoffkuchen kann daher einwandfrei entfernt werden, ohne dass Reste zurückbleiben bzw. Beschädigungen der Trommelinnenwand verursacht werden. Am unteren Ende des Innen- gehäuses 2 befindet sich ein Auslass 15. The solid cake can therefore be removed properly without leaving residues or causing damage to the drum inner wall. At the lower end of the inner housing 2 there is an outlet 15.
Figur 2 zeigt eine weitere Ausführungsform einer derartigen Zentrifuge im Teilvertikalschnitt. Die Zentrifuge weist ein Außengehäuse 1 auf, das ebenfalls einen relativ großen Raum umgibt, in dem ein eine Zentrifugentrommel 3 umgebendes Innengehäuse 2 angeordnet ist. Auch bei dieser Ausführungsform ist das Innengehäuse 2 mit einem Deckel 14 versehen, der am Lagergehäuse 5, und · zwar an einer Lagerbuchse 7 des Lagergehäuses, befestigt ist. Das Wellenlager 5 ist in ei- ner Öffnung des Außengehäuses 1 in abgedichteter Weise montiert und hat ebenfalls einen kugelkalottenförmigen Abschnitt 6, mit dem das Lager schwenkbar bzw. flexibel in einer entsprechenden sphärisch ausgebildeten Lagerpfanne des fest am Außengehäuse 1 angebrachten Teiles des Wellen- lagers 5 gelagert ist. Die Lagerbuchse 7 kann somit Schwenkbewegungen relativ zum Außengehäuse 1 ausführen, wobei sich das Innengehäuse 2 mitbewegt. FIG. 2 shows a further embodiment of such a centrifuge in the partial vertical section. The centrifuge has an outer housing 1, which also surrounds a relatively large space in which a surrounding a centrifuge drum 3 inner housing 2 is arranged. Also in this embodiment, the inner housing 2 is provided with a lid 14 which is fixed to the bearing housing 5, and indeed on a bearing bush 7 of the bearing housing. The shaft bearing 5 is mounted in an opening of the outer housing 1 in a sealed manner and also has a spherical cap portion 6, with which the bearing pivotally or flexibly in a corresponding spherical bearing cup of the firmly attached to the outer housing 1 part of the shaft bearing fifth is stored. The bearing bush 7 can thus Execute pivoting movements relative to the outer housing 1, wherein the inner housing 2 moves.
Ein geeigneter Wellenantrieb 12 in der Form eines Elektro- motors ist außerhalb des Außengehäuses 1 angeordnet. Eine Abdeckung 13 dient zur Abdeckung des Wellenlagers 5. Im Inneren der Lagerbuchse 7 sind wie bei der ersten Ausführungsform ein oder mehrere Wälzlager angeordnet, die die Welle 4 drehbar innerhalb der Lagerbuchse 7 lagern. Die Welle 4 kann somit eine Drehbewegung und eine Schwenk- bzw. Pendelbewegung ausführen. A suitable shaft drive 12 in the form of an electric motor is arranged outside of the outer housing 1. A cover 13 serves to cover the shaft bearing 5. In the interior of the bearing bush 7, as in the first embodiment, one or more rolling bearings are arranged, which support the shaft 4 rotatably within the bearing bush 7. The shaft 4 can thus perform a rotational movement and a pivoting or pendulum motion.
Eine Entfernungseinrichtung 9 zur Entfernung des Feststoffkuchens ist am Deckel 14 des Innengehäuses 2 bzw. an der Lagerbuchse 7 befestigt. Die Entfernungseinrichtung 9 weist einen sich durch den Deckel des Innengehäuses 2 erstreckenden Arm 10 auf, der entsprechende Messer 11 zur Entfernung des Feststoffkuchens trägt. Am unteren Ende des Innengehäuses ist ein Auslass 15 angeordnet. Ferner weist das Innen- gehäuse ein Schauglas 17 auf, mit dem eine Beobachtung der Zentrifugentrommel 3 möglich ist. A removal device 9 for removing the solids cake is fastened to the cover 14 of the inner housing 2 or to the bearing bush 7. The removal device 9 has an arm 10 which extends through the cover of the inner housing 2 and carries corresponding knives 11 for removing the solids cake. At the lower end of the inner housing, an outlet 15 is arranged. Furthermore, the inner housing has a sight glass 17, with which an observation of the centrifuge drum 3 is possible.
Ferner ist in Figur 2 ein Antrieb 16 dargestellt, der an der Innenseite des Außengehäuses 1 angebracht ist und mit dem das Innengehäuse 2 nach Entfernung des Deckels 4 absenkbar ist, um die Zentrifugentrommel 3 inspizieren und warten zu können. Further, a drive 16 is shown in Figure 2, which is mounted on the inside of the outer housing 1 and with which the inner housing 2 is lowered after removal of the lid 4 in order to inspect the centrifuge drum 3 and to wait.
Auch bei dieser Ausführungsform ist durch die Montage des Innengehäuses 2 am Wellenlager 5 und der Entfernungseinrichtung 9 am Deckel 14 des Innengehäuses 2 bzw. an der L gerbuchse 7 sichergestellt, dass Innengehäuse und Entfernungseinrichtung 9 die Schwenk- bzw. Pendelbewegungen der Welle 4 mitmachen, so dass zwischen dem Arm 10 und der Welle 4 bzw. der Trommelwand immer Parallelität herrscht. Also in this embodiment, by mounting the inner housing 2 on the shaft bearing 5 and the removal device 9 on the cover 14 of the inner housing 2 and L, respectively gerbuchse 7 ensures that inner housing and removal device 9 join the pivoting or oscillating movements of the shaft 4, so that there is always parallelism between the arm 10 and the shaft 4 and the drum wall.
