Description

Die Erfindung betrifft eine Separatoranordnung nach dem Oberbegriff des Anspruchs 1.The invention relates to a separator arrangement according to the preamble of claim 1.

Für verschiedene Anwendungen von Separatoren, so insbesondere im Bereich der Medizin- oder Lebensmitteltechnik oder auf dem Gebiet der Milchverarbeitung werden Zentrifugentrommeln in einem Raum angeordnet und betrieben, der relativ zur Umgebung einen Unterdruck aufweist.For various applications of separators, particularly in the field of medical or food technology or in the field of milk processing, centrifuge drums are arranged and operated in a room that has a negative pressure relative to the environment.

Die in der gattungsgemäßen EP 1 119 416 B1 dargestellte Separatoranordnung und ihr in der Praxis eingesetztes Pendant weisen eine Separatortrommel zur Flüssig-/Flüssig-/Fest-Trennung mit einer vertikalen Drehachse auf, welche in einem abgedichteten Behältnis bzw. Haubenraum angeordnet ist, in welchem mit einer Pumpe ein Unterdruck gegenüber der Umgebung erzeugt werden kann. Die Separatortrommel weist ein Zulaufrohr auf sowie eine oder mehrere Schälscheiben zum Austrag der einen oder mehreren Flüssigkeitsphase sowie Feststoffaustragsöffnungen zum kontinuierlichen oder intermittierenden Austrag von Feststoffen.Those in the generic EP 1 119 416 B1 The separator arrangement shown and its counterpart used in practice have a separator drum for liquid/liquid/solid separation with a vertical axis of rotation, which is arranged in a sealed container or hood space in which a negative pressure relative to the environment is generated by a pump can be. The separator drum has an inlet pipe and one or more peeling disks for discharging the one or more liquid phases as well as solids discharge openings for the continuous or intermittent discharge of solids.

Eine Separatoranordnung gemäß dem Oberbegriff des Anspruchs 1 ist aus der WO 2010/101524 A2 bekannt. Die gattungsgemäße Konstruktion und ihre Arbeitsweise haben sich an sich bewährt. Dennoch besteht ein Bedarf nach einer weiteren Verbesserung der bekannten Separatoranordnung und des Verfahrens zu ihrem Betrieb.A separator arrangement according to the preamble of claim 1 is from WO 2010/101524 A2 known. The generic construction and its mode of operation have proven themselves. However, there is a need for further improvement in the known separator assembly and the method of operating it.

Die Erfindung löst diese Aufgabe durch den Gegenstand der Ansprüche 1 und 10. Es wird auch der Antriebsraum unter Unterdruck gegenüber der Umgebung gesetzt, insbesondere, um an rotierenden Teilen dieses Bereichs eine Energieersparnis zu erreichen.The invention solves this problem through the subject matter of claims 1 and 10. The drive chamber is also placed under negative pressure relative to the environment, in particular in order to achieve energy savings on rotating parts of this area.

In dem Komponenten der Antriebseinrichtung - insbesondere Motor-, Kupplungs-, Spindel-, Lager- und/oder sonstige Antriebskomponenten - enthaltenden Raum wird dazu ganz oder jedenfalls in einem Teilbereich ein Unterdruck relativ zur Umgebung erzeugt.For this purpose, in the space containing components of the drive device - in particular motor, coupling, spindle, bearing and / or other drive components - a negative pressure is generated relative to the environment in whole or at least in a partial area.

Hierzu ist der Antriebsraumbereich mit einer Pumpe oder einer sonstigen Unterdruck erzeugenden Einrichtung evakuierbar und/oder er ist mit dem (Hauben-)Raum, welcher die Trommel umgibt verbunden, so dass eine Pumpe bzw. eine entsprechende Einrichtung, welche ergänzend in diesem Raum ein Vakuum erzeugt, auch in dem Antriebsraum "mit" ein Vakuum erzeugen kann. Da auch der Haubenraum, in welchem die Trommel angeordnet ist, unter Unterdruck gegenüber der Umgebung gesetzt wird, ist zudem auch hier eine Energieersparnis zu erreichen. Ein Antriebsraum einer Laborzentrifuge unter Vakuum (die nicht kontinuierlich arbeitet) ist aus der JP 2032 058359 W bekannt.For this purpose, the drive room area can be evacuated with a pump or another device that generates negative pressure and / or it is connected to the (hood) room that surrounds the drum, so that a pump or a corresponding device, which additionally creates a vacuum in this room generated, can also create a vacuum in the drive room. Since the hood space in which the drum is arranged is also placed under negative pressure relative to the environment, energy savings can also be achieved here. A drive compartment of a laboratory centrifuge under vacuum (which does not operate continuously) is from the JP 2032 058359 W known.

Besonders vorteilhaft ist nach einer Variante ein Unterdruckanschluss auf besonders großem Radius im Haubenraum, da sich hier die Trommeldrehung unterstützend auf die Erzeugung des Vakuums auswirkt. Vorzugsweise sind dabei sowohl die Trommel als auch der Haubenraum abschnittsweise konisch ausgebildet.According to one variant, a vacuum connection on a particularly large radius in the hood space is particularly advantageous, since here the drum rotation has a supporting effect on the generation of the vacuum. Both the drum and the hood space are preferably designed to be conical in sections.

Eine Variante für einen Unterdruckanschluss kann ein Anschluss über eine Bohrung in der Spindel sein. In diesem Fall wird das freie Ende der Spindel unten durch die abgedichtete Gestellwandung geführt und über abgedichtete Anschlüsse erfolgt die Anbindung an ein Unterdrucksystem. Die Bohrung in der Spindel endet im Bereich unterhalb der Trommel im Haubenraum. Die Durchführung der Spindel durch die Gestellwandung ist ebenfalls mittels schleifenden Elementen abgedichtet.A variant for a vacuum connection can be a connection via a hole in the spindle. In this case, the free end of the spindle is guided through the sealed frame wall at the bottom and the connection to a vacuum system is made via sealed connections. The hole in the spindle ends in the area below the drum in the hood space. The passage of the spindle through the frame wall is also sealed using sliding elements.

Als Flüssigkeitsabläufe in der Trommel eignen sich übliche Schälscheiben. Es ist aber auch eine Abdichtung/Isolierung der Greifer / Trommel mittels einer Tauchscheibe denkbar.Conventional peeling discs are suitable as liquid drains in the drum. However, sealing/insulating the gripper/drum using a diving disk is also conceivable.

Zum technologischen Hintergrund sei noch die nicht kontinuierlich nutzbare Laborzentrifuge der JP 32 58 359 A genannt, bei der die zu schleudernden Produkte in Probengläsern aufgenommen sind, so dass das Produkt beim Schleudern gut geschützt ist.The technological background is the laboratory centrifuge, which cannot be used continuously JP 32 58 359 A called, in which the products to be spun are held in sample glasses so that the product is well protected during centrifuging.

Besonders vorteilhaft ist ein Einsatz eines fluid-, insbesondere öl- oder wassergekühlten Motors.It is particularly advantageous to use a fluid-, in particular oil- or water-cooled, engine.

Vorteilhaft erscheint es, auch das Ölschmierungssystem, insbesondere ein Umlaufschmierungssystem im Vakuumbereich anzuordnen, insbesondere mit einem oder mehreren der folgenden Merkmale:

  • Ölumlaufpumpe im Vakuumbereich
  • Ölbehälter im Vakuumbereich,
  • Wärmetauscher (für Ölkreislauf) im Vakuumbereich
It appears advantageous to also arrange the oil lubrication system, in particular a circulation lubrication system, in the vacuum range, in particular with one or more of the following features:
  • Oil circulation pump in the vacuum area
  • Oil container in the vacuum area,
  • Heat exchanger (for oil circuit) in the vacuum area

Vorteilhaft erscheint auch eine Kühlfluidzufuhr durch die Trommel (nach Art der DE 19922237 ).A supply of cooling fluid through the drum (in the manner of DE 19922237 ).

Besonders vorteilhaft ist zudem, wenn im Betrieb ein Unterdruck unter dem Atmosphärendurck, insbesondere 0,3 bar kleiner als dieser, vorzugsweise 0,4 bar kleiner als dieser, insbesondere 0,7 bar kleiner als dieser erzeugt wird.It is also particularly advantageous if, during operation, a negative pressure is generated below the atmospheric pressure, in particular 0.3 bar smaller than this, preferably 0.4 bar smaller than this, in particular 0.7 bar smaller than this.

Es ist ferner vorteilhaft, wenn der Wert des Unterdruckes jedenfalls im Haubenraum mit der Trommel während des Betriebs abhängig vom Betriebszustand verändert wird. So kann beispielsweise zeitlich vor, bei oder nach einer Änderung des Betriebszustandes auch eine Änderung des Unterdruckes erfolgen. Dabei kann die Änderung des Betriebszustandes, die vor, bei oder nach der Änderung des Unterdruckes erfolgt, eine Feststoffentleerung sein. Beispielsweise kann der Unterdruck kurz vor oder zumindest während der Entleerung etwas erhöht werden (z.B. von 0,2 bar auf 0,5 bar) und nach der Entleerung wieder abgesenkt werden (z.B. wieder auf 0, 2bar), damit bei der Feststoffentleerung keine nachteiligen Effekte aufgrund des hohen Unterdruckes auftreten.It is also advantageous if the value of the negative pressure in the hood space with the drum is changed during operation depending on the operating state. For example, a change in the negative pressure can also take place before, during or after a change in the operating state. The change in the operating state that occurs before, during or after the change in negative pressure can be an emptying of solids. For example, the negative pressure can be increased slightly shortly before or at least during emptying (e.g. from 0.2 bar to 0.5 bar) and lowered again after emptying (e.g. back to 0.2 bar), thus during solids emptying no adverse effects occur due to the high negative pressure.

Nach einer weiteren vorteilhaften Variante kann beispielsweise die Änderung des Betriebszustandes, vor, bei oder nach der Änderung des Unterdruckes erfolgt, eine Anlauf- oder Abfahr-/Auslaufphase sein.According to a further advantageous variant, for example, the change in the operating state that occurs before, during or after the change in negative pressure can be a start-up or shutdown/run-down phase.

Besonders geeignet ist die Erfindung für eine Separatoranordnung mit einem Separator mit einer Trommel mit vertikaler Drehachse, die auf eine drehbare Spindel aufgesetzt und von einer Haube umgeben ist, wobei die Trommeln einen Trommeldurchmesser größer 500 mm, insbesondere 800 mm, ganz besonders bevorzugt größer 900 mm und/oder Drehzahlen z.B. größer 8000 U/min, 5000 U/min, 4000 U/min im Betrieb aufweisen.The invention is particularly suitable for a separator arrangement with a separator with a drum with a vertical axis of rotation, which is placed on a rotatable spindle and surrounded by a hood, the drums having a drum diameter greater than 500 mm, in particular 800 mm, very particularly preferably greater than 900 mm and/or speeds e.g. greater than 8000 rpm, 5000 rpm, 4000 rpm during operation.

Vorzugsweise beträgt die die Umfangsgeschwindigkeit am Trommelaußendurchmesser wenigstens 100 m/s oder mehr.Preferably, the peripheral speed at the outer diameter of the drum is at least 100 m/s or more.

Die Oberfläche der Trommel beträgt ferner vorzugsweise 0,5m2 bis 5m2, insbesondere 1-3,5 m2, damit sich die Wirkung der Unterstützung der Unterdruckerzeugung besonders vorteilhaft auswirkt.The surface area of the drum is also preferably 0.5m 2 to 5m 2 , in particular 1-3.5 m 2 , so that the effect of supporting the negative pressure generation has a particularly advantageous effect.

Weitere vorteilhafte Ausgestaltungen sind in den übrigen Unteransprüchen angegeben.Further advantageous refinements are specified in the remaining subclaims.

Nachfolgend wird die Erfindung unter Bezug auf die Zeichnung anhand eines Ausführungsbeispiels näher beschrieben. Es zeigen:

Fig. 1 zeigt eine Separatoranordnung 1 mit einem Separator mit vertikaler Drehachse D, der eine drehbare Trommel 2 aufweist, die auf eine drehbare Antriebsspindel 3 aufgesetzt ist. Die Produktzuleitung eines im kontinuierlichen Betrieb verarbeitbaren Produktes P erfolgt vorzugsweise von oben durch ein Zuleitungsrohr 4 (hier nicht detailliert dargestellt). Dieser Aufbau wird bevorzugt. Es ist aber auch eine hängende Trommel mit einem Antrieb oberhalb der Trommel realisierbar. Fig. 1 shows a separator arrangement 1 with a separator with a vertical axis of rotation D, which has a rotatable drum 2 which is placed on a rotatable drive spindle 3. The product supply of a product P that can be processed in continuous operation is preferably carried out from above through a supply pipe 4 (not shown in detail here). This structure is preferred. However, a hanging drum with a drive above the drum can also be implemented.

Bei der Verarbeitung im kontinuierlichen Betrieb wird das zu verarbeitende Produkt kontinuierlich in die Trommel geleitet bzw. zugeführt, kontinuierlich zentrifugiert und wenigstens eine oder sämtliche der bei der Klärung und/oder Trennung gebildeten Phasen wird/werden auch kontinuierlich abgeleitet. Flüssigkeitsphase(n) wird/werden kontinuierlich abgeleitet. Eine ggf. auch gebildete Feststoffphase kann kontinuierlich durch Düsen oder nicht kontinuierlich beispielsweise mit von Kolbenschiebern verschließbaren Öffnungen ausgetragen werden.During processing in continuous operation, the product to be processed is continuously fed into the drum, continuously centrifuged and at least one or all of the phases formed during the clarification and/or separation are also continuously removed. Liquid phase(s) is/are continuously drained away. Any solid phase that may also be formed can be discharged continuously through nozzles or non-continuously, for example with openings that can be closed by piston valves.

Die Trommel 2 ist hier dazu ausgelegt, das zu verarbeitende Produkt P in wenigstens eine Flüssigkeitsphase L oder mehrere Flüssigkeitsphasen sowie eine Feststoffphase S zu trennen. Sie weist hier wie die Trommel der EP 1 119 416 B1 bzw. das in der Praxis eingesetzte Pendant im Inneren vorzugsweise einen Trenntellerstapel aus Trenntellern auf (hier nicht zu erkennen).The drum 2 is designed here to separate the product P to be processed into at least one liquid phase L or several liquid phases and a solid phase S. It points here like the drum of the EP 1 119 416 B1 or the counterpart used in practice preferably has a stack of separating plates inside (not visible here).

Die Flüssigkeitsphasen L werden über Flüssigkeitsauslässe, insbesondere Schälscheiben nach Art einer Zentripetalpumpe, aus der Trommel 2 abgeleitet. Die Ableitung der Feststoffphase S erfolgt dagegen entweder diskontinuierlich an diskontinuierlich verschließbaren Feststoffaustragsöffnungen 5 im Trommelmantel oder kontinuierlich durch Düsen im Trommelmantel.The liquid phases L are drained from the drum 2 via liquid outlets, in particular peeling disks in the manner of a centripetal pump. The solids phase S, on the other hand, is discharged either discontinuously at discontinuously closable solids discharge openings 5 in the drum shell or continuously through nozzles in the drum shell.

Vorteilhaft erscheint der Einsatz insbesondere eines flüssigkeitsgesteuerten Kolbenschiebers.The use of a liquid-controlled piston valve in particular appears to be advantageous.

Die Trommel 2 ist in einen gegen die Umgebung abgedichtet ausgebildeten Haubenraum 6 eingesetzt.The drum 2 is inserted into a hood space 6 that is sealed against the environment.

Dieser Haubenraum 6 wird hier von einer Haube 7, die an einem Fundament - hier einem Maschinengestell 8 - festgelegt ist, einer Abdeckung 9 unterhalb der Trommel, die an der Haube 7 festgelegt ist sowie einem Spindelgehäuse 10 begrenzt, welches von der Antriebsspindel 3 durchsetzt ist, festgelegt.This hood space 6 is delimited here by a hood 7, which is fixed to a foundation - here a machine frame 8 -, a cover 9 below the drum, which is fixed to the hood 7, and a spindle housing 10, which is penetrated by the drive spindle 3 , fixed.

Dabei sind vorzugsweise zwischen aneinander grenzende Elemente wie zwischen die Haube 7 und das Maschinengestell 8 sowie zwischen die Abdeckung 9 und die Haube 7 sowie zwischen die Abdeckung 9 und das Spindelgehäuse 10 und zwischen dem Spindelgehäuse (fest) und die Antriebsspindel 3 (die sich im Betrieb dreht) geeignete Dichtungen angeordnet, um eine abgedichtete Bauweise zu realisieren.There are preferably between adjacent elements such as between the hood 7 and the machine frame 8 and between the cover 9 and the hood 7 as well as between the cover 9 and the spindle housing 10 and between the spindle housing (fixed) and the drive spindle 3 (which is in operation rotates) suitable seals are arranged to realize a sealed construction.

In der Haube 7 ist ferner ein Feststofffänger 11 ausgebildet, welcher dazu dient, aus der Trommel austrende Feststoffe aus dem Haubenraum durch eine Feststoffableitung 12 abzuleiten.A solids catcher 11 is also formed in the hood 7, which serves to divert solids escaping from the drum from the hood space through a solids discharge line 12.

An den Haubenraum 6 ist ferner an einem Unterdruckanschluss 13 eine Pumpe 14a (oder eine sonstige Einrichtung zum Senken des Druckes in dem Haubenraum 6 gegenüber der Umgebung) angeschlossen, mit welcher in dem Haubenraum 6 ein Unterdruck gegenüber der Umgebung U außerhalb des Haubenraumes 6 erzeugbar ist.A pump 14a (or another device for lowering the pressure in the hood space 6 relative to the environment) is also connected to a vacuum connection 13 to the hood space 6, with which a negative pressure relative to the environment U outside the hood space 6 can be generated in the hood space 6 .

Vorzugsweise ist dieser Unterdruckanschluss 13 an einer Stelle ausgebildet, welche relativ zur Drehachse D auf einem relativ großen Radius Rp liegt, insbesondere auf einem Radius, der gleich oder größer ist als der größte Radius RT der Trommel 2.This vacuum connection 13 is preferably formed at a location which lies on a relatively large radius R p relative to the axis of rotation D, in particular on a radius which is equal to or larger than the largest radius R T of the drum 2.

Durch den Betrieb bei Unterdruck, insbesondere bei einem Unterdruck, der mehr als 0,2 bar niedriger ist als der Umgebungsdruck in der Umgebung U, kann der Energieverbauch zum Antrieb der Trommel 2 gesenkt werden. Dies ist an sich allerdings bereits bekannt, so aus dem eingangs genannten Stand der Technik.By operating at negative pressure, especially at a negative pressure that is more than 0.2 bar lower than the ambient pressure in the area U, the energy consumption for driving the drum 2 can be reduced. However, this is already known per se, from the prior art mentioned at the beginning.

Gegenüber dem Stand der Technik wird der Energieverbrauch der Separatoranordnung 1 hier sodann nochmals dadurch weiter gesenkt, dass nicht nur der Haubenraum 6, in welchem die Trommel 2 angeordnet ist, sondern auch ein Antriebsraum 15, in welchem eine oder mehrere Komponenten eines Separatorantriebs 16 angeordnet sind, so abgedichtet ausgelegt ist, dass in ihm wiederum mit wenigstens einer weiteren Pumpe 14b oder ebenfalls mit der Pumpe 14a ein Unterdruck, insbesondere ein Unterdruck von mehr als 0,2 bar, gegenüber dem Umgebungsdruck in der Umgebung U erzeugt werden kann bzw. im Betrieb erzeugt wird.Compared to the prior art, the energy consumption of the separator arrangement 1 is further reduced here in that not only the hood space 6, in which the drum 2 is arranged, but also a drive space 15, in which one or more components of a separator drive 16 are arranged , is designed to be sealed in such a way that a negative pressure, in particular a negative pressure of more than 0.2 bar, compared to the ambient pressure in the environment U can be generated in it with at least one further pump 14b or also with the pump 14a or during operation is produced.

Der Antriebsraum 15 wird hier einer Antriebsumhausung 17 begrenzt, die entsprechend der Aufgabe, in dem Antriebsraum 15 einen Unterdruck gegenüber der Umgebung U zu erzeugen, wiederum in entsprechend abgedichteter Bauart ausgeführt ist. Dazu sind nach Fig. 1 zwischen Elementen der Antriebsumhausung 17 wiederum geeignete Dichtungen 18 ausgebildet.The drive chamber 15 is delimited here by a drive housing 17, which is in turn designed in a correspondingly sealed design in accordance with the task of generating a negative pressure in the drive chamber 15 relative to the environment U. This is what we are looking for Fig. 1 between elements of the drive housing 17, suitable seals 18 are formed.

Hier wird der Antriebsraum 15 von dem Maschinengestell 8 sowie Verschlussplatten 19 umgrenzt, die Öffnungen des Maschinengestells verschließen. Nach oben hin wird er von der Abdeckung 9 unterhalb der Trommel 2 und dem ein- oder mehrteiligen Spindelgehäuse 10 begrenzt.Here the drive space 15 is delimited by the machine frame 8 and closure plates 19, which close openings in the machine frame. At the top it is limited by the cover 9 below the drum 2 and the one-part or multi-part spindle housing 10.

Die Pumpe 14b ist an einen Unterdruckanschluss 20 des Antriebsraumes 15 anschließbar.The pump 14b can be connected to a vacuum connection 20 of the drive chamber 15.

Im Antriebsraum 15 sind eines oder mehrere oder sogar sämtliche Elemente des Separatorantriebs 16 untergebracht. Lediglich die Antriebsspindel 3 ragt nach Fig. 1 aus dem Antriebsraum heraus mit ihrem oberen Ende in den Haubenraum.One or more or even all elements of the separator drive 16 are accommodated in the drive chamber 15. Only the drive spindle 3 protrudes Fig. 1 from the drive compartment with its upper end into the hood compartment.

Vorzugsweise ist die Spindellagerung ganz oder teilweise - hier sowohl ein Halslager 21a als auch ein Fußlager 21b - im Unterdruckbereich angeordnet. Es ist aber auch denkbar, dass eines (insbesondere das Halslager 21a) oder beide Lager 21a, b nicht zu diesem Unterdruckbereich gehören.The spindle bearing is preferably arranged entirely or partially - here both a neck bearing 21a and a foot bearing 21b - in the negative pressure area. However, it is also conceivable that one (in particular the neck bearing 21a) or both bearings 21a, b do not belong to this negative pressure area.

Das Spindelgehäuse 10 liegt in einem Flanschbereich an elastischen Elementen 40 abgestützt auf dem Maschinengestell 8 auf.The spindle housing 10 is supported on the machine frame 8 in a flange area on elastic elements 40.

Ebenfalls bevorzugt im Unterdruckbereich angeordnet ist der Antriebsmotor 22 angeordnet, der hier direkt in axialer Verlängerung der Antriebspindel 3 ausgebildet ist, so dass ein sogenannter Direktantrieb für die Trommel 2 gebildet wird.Also preferably arranged in the negative pressure area is the drive motor 22, which is formed here directly in the axial extension of the drive spindle 3, so that a so-called direct drive for the drum 2 is formed.

Der Rotor 22a ist hier direkt an der Antriebsspindel 3 befestigt und der Stator 22b ist im einem Motorgehäuse 23, welches wiederum an der von dem Haubenraum 6 abgewandten Seite des Maschinengestells 8 befestigt ist. Gerade ein solcher Direktantrieb ist bevorzugt im Antriebsraum unterbringbar, wobei der elektrische Antriebsmotor 22 aber auch zwischen den Lagern 21a, b angeordnet sein könnte (letztere Variante hier nicht dargestellt). Es ist ferner auch denkbar, den Antriebsmotor im Unterdruckbereich des Antriebsraums 15 unterzubringen, der über eine Kupplung mit der Antriebsspindel 3 verbunden ist (hier ebenfalls nicht dargestellt).The rotor 22a is attached here directly to the drive spindle 3 and the stator 22b is in a motor housing 23, which in turn is attached to the side of the machine frame 8 facing away from the hood space 6. Such a direct drive can preferably be accommodated in the drive space, although the electric drive motor 22 could also be arranged between the bearings 21a, b (the latter variant not shown here). It is also conceivable to accommodate the drive motor in the negative pressure area of the drive chamber 15, which is connected to the drive spindle 3 via a coupling (also not shown here).

Im Antriebsraum 15 ist zudem ein Schmierungssystem 24 angeordnet, welches zur Schmierung der Spindellagerung 21 und/oder zur Schmierung von Komponenten am Motor dient.A lubrication system 24 is also arranged in the drive chamber 15, which serves to lubricate the spindle bearing 21 and/or to lubricate components on the engine.

Das Schmierungssystem weist hier einen Schmiermittelkreislauf auf, welcher die Elemente Ölbehälter 25, Pumpe 26, Zuleitung 27a, b zu der Spindellagerung 21, Ölauffangbehälter 28, der drehfest mit der Spindel verbunden ist und in dem sich im Betrieb aufgrund der topfartigen Gestaltung auf einem Radius ein Ölpegel ausbildet, ein Schälorgan 29, welches das Öl im Auffangbehälter ableitet, sowie eine Rückleitung 27c, d in den Ölbehälter 25 aufweist. Hier sind all diese Elemente des Schmierungssystems vorteilhaft und kompakt in dem Unterdruckbereich, d.h. im Antriebsraum, untergebracht.The lubrication system here has a lubricant circuit, which has the elements oil container 25, pump 26, supply line 27a, b to the spindle bearing 21, oil collecting container 28, which is connected to the spindle in a rotationally fixed manner and in which it is located on a radius during operation due to the cup-like design Oil level forms, a peeling element 29, which drains the oil in the collecting container, and a return line 27c, d into the oil container 25. Here, all of these elements of the lubrication system are advantageously and compactly accommodated in the negative pressure area, i.e. in the drive room.

In den Antriebsraum münden hier ferner Ab- und Zuleitungen 30, 31, 32, 33 von einem oder mehreren Kühlmittelkreisläufen, hier einmal für den Motor 22 sowie einmal für das Schmierungssystem 24.Outflow and supply lines 30, 31, 32, 33 from one or more coolant circuits also open into the drive chamber, here once for the motor 22 and once for the lubrication system 24.

Im Maschinengestell sind ferner eine oder mehrere Durchgangsöffnungen 34, 35, 36, 37 ausgebildet, welche dafür sorgen, dass innerhalb des Antriebsraums 15 möglichst keine Druckgradienten entstehen.One or more through openings 34, 35, 36, 37 are also formed in the machine frame, which ensure that, if possible, no pressure gradients arise within the drive chamber 15.

Da im Antriebsraum 15 relativ zur Umgebung ebenfalls ein Unterdruck erzeugt wird, kann auch an den sich drehenden Teilen im Antriebsraum eine weitere Energieersparnis im Betrieb erreicht werden.Since a negative pressure is also generated in the drive chamber 15 relative to the environment, further energy savings can also be achieved during operation on the rotating parts in the drive chamber.

Zu erwähnen ist noch, dass der gesamte Separator bzw. das Maschinengestell an elastischen Fußelementen 38 auf einem Fundamt 39 abgestützt ist.It should also be mentioned that the entire separator or the machine frame is supported on elastic foot elements 38 on a foundation 39.

Nach Fig. 2 sind der Haubenraum 6 und der Antriebsraum 15 nicht gegeneinander abgedichtet. Hier wird das beispielhaft und einfach dadurch erreicht, dass die Abdeckung 9 unterhalb der Trommel 2 nicht radial innen zum Spindelgehäuse 10 abgedichtet ist sondern dass zwischen diesen Elementen ein Spalt 42 ausgebildet ist, der für einen Druckausgleich zwischen dem Haubenraum 6 und dem Antriebsraum 15 sorgt. Hierbei wird keine Abdichtung, z.B. keine Gleitringdichtung benötigt.After Fig. 2 the hood space 6 and the drive space 15 are not sealed against each other. Here, this is achieved by way of example and simply in that the cover 9 below the drum 2 is not sealed radially on the inside of the spindle housing 10, but rather that a gap 42 is formed between these elements, which ensures pressure equalization between the hood space 6 and the drive space 15. No sealing, e.g. no mechanical seal, is required.

Derart kann ggf. sogar mit nur einer einzigen Pumpe 14a der Unterdruck in beiden Räumen 6, 15 gleichzeitig erzeugt werden. Es können aber auch mehrere Pumpen vorgesehen sein.In this way, the negative pressure can even be generated in both rooms 6, 15 at the same time with just a single pump 14a. However, several pumps can also be provided.

Insgesamt ist auch nach Fig. 2 sowohl der Bereich innerhalb der Haube 7 mitsamt dem Antriebsraum 15 mit einer oder mehreren insbesondere auch drehbare Antriebskomponenten enthaltend, gegenüber der Umgebung U der Haube 7 so abgedichtet, das es möglich ist, diesen Bereich mit einer Pumpe 14a, b, die Luft/Gas aus dem Bereich zwischen der Haube 7 und der Trommel 2 und/oder dem Antriebsraum 15 pumpen kann, unter Unterdruck relativ zur Umgebung U zu setzen.Overall is also after Fig. 2 both the area within the hood 7 together with the drive chamber 15 containing one or more drive components, in particular also rotatable drive components, relative to the environment U Hood 7 is sealed in such a way that it is possible to close this area under negative pressure relative to the environment U with a pump 14a, b, which can pump air/gas from the area between the hood 7 and the drum 2 and/or the drive chamber 15 set.

Die gesamte Energie des Motors und die Ölversorgung des Antriebes (Motors) erfolgt auch nach Fig. 2 im geschlossenen Antriebsraum 15.The entire energy of the engine and the oil supply to the drive (motor) also takes place after Fig. 2 in the closed drive room 15.

Nach Fig. 3 ist dagegen keine Umlaufschmierung bzw. kein Schmiermittelkreislauf innerhalb des Antriebsraumes 15 angeordnet. Die Schmierölzu-und Abfuhr erfolgt in diesem Fall über ein extern (außerhalb des Antriebsraumes) installiertes Schmierölaggregat (hier nicht dargestellt).After Fig. 3 On the other hand, there is no circulating lubrication or no lubricant circuit within the drive chamber 15. In this case, the lubricating oil is supplied and removed via a lubricating oil unit (not shown here) installed externally (outside the drive room).

Sämtliche Separatoranordnung der Fig. 1 bis 3 werden auch höchsten Energieeinsparungsanforderungen gerecht.All separator arrangement of the Fig. 1 to 3 meet even the highest energy saving requirements.

Als besonders vorteilhaft ist nochmals zu betonen, dass in Fig. 1 - 3 jeweils die Pumpe 14a zur Erzeugung des Unterstrucks durch Absaugung auf großem, insbesondere größtem Radius/Durchmesser der Haube 7 angeordnet ist.It should be emphasized once again that it is particularly advantageous Fig. 1 - 3 in each case the pump 14a for generating the substructure by suction is arranged on a large, in particular largest, radius/diameter of the hood 7.

Es erfolgt die Absaugung an einem Radius der Haube 7, der bezogen auf die Drehachse auf einem Radius liegt, der größer ist als 80%, insbesondere mehr als 100%, des größten Trommelradius. Vorteilhaft wirkt sich dabei insbesondere die Unterstützung durch die Trommel-Differenzdruckwirkung aus.The suction takes place at a radius of the hood 7, which, based on the axis of rotation, lies on a radius that is greater than 80%, in particular more than 100%, of the largest drum radius. The support provided by the drum differential pressure effect is particularly advantageous.

Denkbar ist auch ein Unterdruckanschluss an einem (hier nicht dargestellten) Feststoffbehälter.A vacuum connection on a solids container (not shown here) is also conceivable.

Ebenfalls vorteilhaft ist ein weiterer Unterdruckanschluss im Steuerwasser-Ablaufbereich unterhalb der Trommel (hier nicht dargestellt).Another vacuum connection in the control water drain area below the drum (not shown here) is also advantageous.

Ebenfalls vorteilhaft und baulich einfach wäre ein weiterer Unterdruckanschluss durch die Spindel 3 in den Antriebsraum 15 (z.B. eine Bohrung bei Maschinen mit externem Ölaggregat).Another vacuum connection through the spindle 3 into the drive chamber 15 would also be advantageous and structurally simple (e.g. a hole in machines with an external oil unit).

Weiter vorteilhaft ist eine abgedichtete/isolierte Ausgestaltung der Schälscheiben mittels einer Tauchscheibe. Weiter vorteilhaft ist ein Einsatz einer hermetischen Greifer / Pumpenkombination (nicht dargestellt).A further advantage is a sealed/insulated design of the peeling disks using a diving disk. It is also advantageous to use a hermetic gripper/pump combination (not shown).

Besonders vorteilhaft ist ein Einsatz eines fluid-, insbesondere öl- oder wasssergekühlten Motors, da durch den Unterdruck im Antriebsraum die Kühlwirkung durch Luft verringert wird.It is particularly advantageous to use a fluid-, in particular oil- or water-cooled, motor, since the negative pressure in the drive chamber reduces the cooling effect of air.

Die Separatoranordnung nach Art der Fig. 1 wird auch höchsten Energieeinsparungsanforderungen gerecht.The separator arrangement according to the type Fig. 1 also meets the highest energy saving requirements.

Vorteilhaft ist auch, das in Fig. 1 die Pumpe (14a) zur Erzeugung des Unterstrucks durch Absaugung auf großem, insbesondere größtem Durchmesser der Haube ausgelegt ist. Insbesondere erfolgt die Absaugung an einem Durchmesser der Haube, der bezogen auf die Drehachse auf einem größeren Radius liegt als der größte Trommelradius. Vorteilhaft wirkt sich dabei insbesondere die Unterstützung durch die Trommel-Differenzdruckwirkung aus.It is also advantageous that in Fig. 1 the pump (14a) is designed to generate the substructure by suction on a large, in particular largest, diameter of the hood. In particular, the suction takes place at a diameter of the hood which, based on the axis of rotation, is at a larger radius than the largest drum radius. The support provided by the drum differential pressure effect is particularly advantageous.

Ebenfalls vorteilhaft ist ein oder ein weiterer Unterdruckanschluss an der Pumpe 14b 14b im Antriebsraum oder auf einem (hier nicht dargestellten Feststoffbehälter im Zentrum mit einem "Verlängerungsrohr" großen Durchmessers zur "Sauberhaltung des Unterdruckanschlusses.Also advantageous is one or another vacuum connection on the pump 14b 14b in the drive room or on a solids container (not shown here) in the center with an "extension pipe" of large diameter to "keep the vacuum connection clean.

Ebenfalls vorteilhaft ist ein oder ein weiterer Unterdruckanschluss an der Pumpe 14b im Antriebsraum oder auf einem Anschluss im Steuerwasser-Ablaufbereich unterhalb der Trommel (ebenfalls nicht dargestellt).Also advantageous is one or another negative pressure connection on the pump 14b in the drive room or on a connection in the control water drain area below the drum (also not shown).
