Description

Die Erfindung betrifft einen Separator mit vertikaler Drehachse nach dem Oberbe griff des Anspruchs 1.The invention relates to a separator with a vertical axis of rotation according to the Oberbe handle of claim 1.

Ein derartiger Separator ist aus der US 4,005,817 bekannt. Ein Separator ist aus der DE 10 2004 038 613 A1 bekannt. Wie in dieser Schrift beschrieben, kommt es bei einem Einsatz von Separatoren zur Entkeimung von Milch u.U. zu kurzzeitigen Verschlechterungen der Entkeimungseffizienz aufgrund von Druckanstiegen im Zulauf, die z. B. durch Teilentleerungen, Tankumschaltungen oder durch einen erhöhten Luftgehalt in dem Produkt hervorgerufen werden. Ein weiteres Problem ist der Transport (Schaftlauf) von Keimen zur Schälscheibe.Such a separator is from the US 4,005,817 known. A separator is out of the DE 10 2004 038 613 A1 known. As described in this document, when using separators for sterilizing milk, there may be brief deteriorations in the sterilizing efficiency due to pressure increases in the feed, which, for. B. caused by partial emptying, tank switching or by an increased air content in the product. Another problem is the transport (shaft run) of germs to the peeling disc.

Zur Lösung dieses Problems wird in der DE 10 2004 038 613 A1 vorgeschlagen, dass Verbindungsbohrungen zu einem Ringraum, welcher oberhalb des freien Endes des Zulaufrohres im Verteiler ausgebildet ist, vorgesehen sind, dass sich die Verbindungsbohrungen zwischen einem vorzugsweise konischen Zulaufraum und dem Ringraum erstrecken, und dass den Austrittsöffnungen aus dem Zulaufraum in die Zulaufbohrungen des Verteilers und den Verbindungsbohrungen zum Ringraum jeweils eine Rippe zugeordnet ist. Hierdurch wird eine besonders gleichmäßige Annahme und Beschleunigung sowie auch eine besonders gleichmäßige Entlüftung des Produktes erreicht, wodurch auch bei erhöhtem Luftgehalt im Produkt relativ konstante Entlüftungswerte erzielbar sind.To solve this problem is in the DE 10 2004 038 613 A1 It is proposed that connection bores to an annular space, which is formed above the free end of the inlet pipe in the distributor, be provided that the connection bores extend between a preferably conical inlet space and the annular space, and that the outlet openings from the inlet space into the inlet bores of the distributor and a rib is assigned to the connection bores to the annulus. This results in a particularly uniform acceptance and acceleration as well as a particularly uniform ventilation of the product, which means that relatively constant ventilation values can be achieved even with an increased air content in the product.

Diese Lösung hat sich an sich bewährt, soll aber insbesondere in konstruktiver Hinsicht und vorzugsweise auch Hinsicht ihrer Wirksamkeit nochmals weiter optimiert werden.This solution has proven itself per se, but should be further optimized, particularly in terms of construction and preferably also in terms of its effectiveness.

Die Lösung dieses Problems ist ausgehend von der US 4,005,817 die Aufgabe der Erfindung.The solution to this problem is based on the US 4,005,817 the object of the invention.

Die Erfindung löst diese Aufgabe durch den Gegenstand des Anspruches 1.The invention solves this problem by the subject matter of claim 1.

Der Rippenkörper ist einfach montierbar. Darüber hinaus lassen sich der Zulaufdruck reduzieren und die Zulaufleistung erhöhen. Hieraus resultiert eine schonendere Produktzuführung im Verteiler. Zudem wird die Gefahr, dass sich im Zulaufbereich Ablagerungen bilden, verringert.The rib body is easy to assemble. In addition, the inlet pressure can be reduced and the inlet capacity increased. This results in a gentler product feed in the distributor. In addition, the risk of deposits forming in the inlet area is reduced.

Die Rippen sind gebogen ausgebildet mit einer schaufelartigen Auslegung mit Krümmungen in allen Raumrichtungen, solange eine Beschleunigungswirkung in Umfangsrichtung gegeben ist.The ribs are curved with a blade-like design with curvatures in all spatial directions as long as there is an acceleration effect in the circumferential direction.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

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

Fig. 1 , 3 and 4 are not according to the invention.

Figur 1 zeigt eine vereinfachte Darstellung eines Teilbereichs einer um eine Drehachse D drehbaren Schleudertrommel 1 eines kontinuierlich betreibbaren Separators, in der ein Tellerpaket 2 aus einer Vielzahl von Tellern 3 konzentrisch zur Maschinenachse bzw. Drehachse D angeordnet ist. Die Schleudertrommel ist hier innen doppelt konisch ausgebildet. Figure 1 shows a simplified representation of a partial area of a centrifugal drum 1 of a continuously operable separator which can be rotated about an axis of rotation D and in which a plate pack 2 comprising a plurality of plates 3 is arranged concentrically to the machine axis or axis of rotation D. The centrifugal drum is double conical on the inside.

Die Teller 3 weisen eine konische Form auf, sind axial übereinander gestapelt und mittels hier nicht dargestellten Abstandshaltern (Laschen und dgl.) voneinander beabstandet.The plates 3 have a conical shape, are stacked axially one above the other and are spaced apart by means of spacers (tabs and the like), not shown here.

Das Tellerpaket 2 ist an einem Verteilerschaft 4 eines Verteilers 5 gehalten, der an seinem Außenumfang mit radial nach außen vorkragenden Stegen versehen ist (hier nicht zu erkennen), welche am Innenumfang der Teller 3 in diese eingreifen. Das Tellerpaket 2 weist Steigekanäle 6 auf, die aus direkt übereinander liegenden Löchern in den Tellern 3 bestehen und sich über die gesamte Höhe des Tellerpakets 2 erstrecken.The plate pack 2 is held on a distributor shaft 4 of a distributor 5, which is provided on its outer circumference with radially outwardly projecting webs (cannot be seen here) which engage on the inner circumference of the plates 3. The plate pack 2 has riser channels 6 which consist of holes in the plates 3 lying directly one above the other and which extend over the entire height of the plate pack 2.

Ein konzentrisch zur Maschinenachse liegendes Zulaufrohr 7 ermöglicht die Zuleitung eines Schleudergutes hier beispielhaft von oben in die Schleudertrommel 1 sowie dort durch den Verteilerschaft 4 und unterhalb des Tellerpakets 2 im Verteiler 5 ausgebildete Verteilerkanäle 8 in das Tellerpaket 2, beispielhaft im Bereich des Steigekanals 6 oder an einer anderen Stelle.A feed pipe 7 located concentrically to the machine axis enables the feed of a centrifugal material here, for example, from above into the centrifugal drum 1 and there through the distributor shaft 4 and below the plate package 2 in the distributor 5, distributor channels 8 into the plate package 2, for example in the region of the riser channel 6 or on another place.

In der Schleudertrommel 1 erfolgt dann kontinuierlich die eigentliche Klärung des zu verarbeitenden Produkts von Feststoffen (z. B. zur Entkeimung) und/oder eine Trennung des Produktes in verschiedene Flüssigkeitsphasen, welche durch eine oder mehrere Ableitungen 9, ggf. auf verschiedenen Durchmessern, z.B. durch Schälscheiben (hier nicht dargestellt) sowie Feststoffaustragsöffnungen 10 aus der Schleudertrommel 1 abgeleitet werden. Hier ist den Feststoffaustragsöffnungen 10 ein Kolbenschieber 11 vorgeschaltet, der vertikal beweglich ist und mit dem die Feststoffaustragsöffnungen geöffnet und verschlossen werden können.In the centrifugal drum 1, the actual clarification of the product to be processed from solids (e.g. for disinfection) and / or a separation of the product into different liquid phases, which are carried out by one or more discharge lines 9, possibly of different diameters, e.g. are derived from the centrifugal drum 1 by peeling discs (not shown here) and solids discharge openings 10. Here the solids discharge openings 10 is preceded by a piston slide 11 which is vertically movable and with which the solids discharge openings can be opened and closed.

Von besonderem Interesse ist hier der Aufbau des Zulaufbereiches von dem im Betreib stillstehenden Zulaufrohr 7 in den sich im Betrieb drehenden Verteiler 4, d.h. von dem sich im Betrieb nicht drehenden System in das sich im Betrieb drehende System.Of particular interest here is the construction of the inlet area from the inlet pipe 7, which is stationary during operation, into the distributor 4 rotating during operation, i.e. from the non-rotating system to the non-rotating system.

Ein durch das Zulaufrohr 7 zugeführtes Produkt tritt aus dem Zulaufrohr 7 zunächst in einen Zulaufraum 12 im Zentrum des Verteilerschaftes 4 ein, wobei sich der freie untere Austritt des Zulaufrohrs 7 bis unterhalb des oberen Randes des Zulaufraumes 12 erstreckt.A product fed through the feed pipe 7 first enters the feed pipe 7 into an feed chamber 12 in the center of the distributor shaft 4, the free lower outlet of the feed pipe 7 extending to below the upper edge of the feed chamber 12.

Die Verteilerkanäle 8 setzen in der Umfangswand 13 des Zulaufrohres an.The distribution channels 8 start in the peripheral wall 13 of the inlet pipe.

Der Zulaufraum 12 ist nach Fig. 1 derart gestaltet, dass in ihn ein Rippenkörper 14 mit einer oder vorzugsweise mehreren Rippen 15 einsetzbar ist. Die Rippenkörper 14 sind drehfest mit der Schleudertrommel, vorzugsweise mit dem Verteiler 4, verbunden.The inlet space 12 is after Fig. 1 designed in such a way that a rib body 14 with one or preferably a plurality of ribs 15 can be inserted into it. The rib bodies 14 are non-rotatably connected to the centrifugal drum, preferably to the distributor 4.

Beispielhaft sind zwei geeignete Rippenkörper 14 in Fig. 3 und 4 dargestellt.Two suitable rib bodies 14 in are exemplary 3 and 4 shown.

Die dargestellten Rippenkörper 14 weisen jeweils einen Basisabschnitt 16 auf. Dieser Basisabschnitt 16 ist vorzugsweise als umfangsgeschlossener Ringabschnitt ausgebildet (Fig. 1', Fig. 2).The rib bodies 14 shown each have a base section 16. This base section 16 is preferably designed as a circumferentially closed ring section ( Fig. 1 ', Fig. 2 ).

Nach Fig.3 und 4 sind die ringförmigen Basisabschnitte 16 eben ausgebildet, so dass sie sich im eingebauten Zustand senkrecht zur Drehachse D erstrecken, nach Fig.1 erstreckt er sich vertikal, nach Fig. 2 ist der Basisabschnitt 16 dagegen konisch ausgebildet.To Fig. 3 and 4 are the annular base portions 16 flat, so that they extend perpendicular to the axis of rotation D after installation Fig. 1 it extends vertically, after Fig. 2 the base section 16, however, is conical.

Der Basisabschnitt 16 wird jeweils mit dem drehenden System, insbesondere mit dem Verteiler 4, drehfest verbunden.The base section 16 is connected to the rotating system, in particular to the distributor 4, in a rotationally fixed manner.

Die Form des Basisabschnitts 16 entspricht jeweils vorzugsweise der Formgebung des Verteilers 4 in einem entsprechenden Anlage- bzw. Auflagebereich.The shape of the base section 16 preferably corresponds to the shape of the distributor 4 in a corresponding contact or support area.

Von dem ringförmigen Basisabschnitt 16 stehen die Rippen 15 vertikal senkrecht vor und im eingebauten Zustand sind sie ebenfalls vertikal ausgerichtet.The ribs 15 project vertically vertically from the annular base section 16 and, in the installed state, they are also oriented vertically.

Die Basisabschnitte 16 der Ausführungsbeispiele der Fig. 3 und 4 werden vorzugsweise vertikal nach unten hin ausgerichtet, so dass die Rippen 15 vertikal nach oben in den Zulaufraum 12 ragen.The base sections 16 of the embodiments of FIGS 3 and 4 are preferably aligned vertically downwards, so that the ribs 15 project vertically upwards into the inlet space 12.

Die Rippen 15 der Ausführungsbeispiele sind einstückig mit dem Basisabschnitt 16 ausgebildet und stehen von dessen einer Axialseite vertikal vor. Die Rippen 15 sind an dem Basiskörper 16 umfangsverteilt ausgebildet. Die radiale Länge der Rippen 15 entspricht vorzugsweise zumindest der vertikalen Höhe der Eintrittsöffnungen 17 in die Verteilerkanäle 8.The ribs 15 of the exemplary embodiments are formed in one piece with the base section 16 and project vertically from one axial side thereof. The ribs 15 are formed circumferentially distributed on the base body 16. The radial length of the ribs 15 preferably corresponds at least to the vertical height of the inlet openings 17 into the distribution channels 8.

Die Rippen 15 sind nach einer Variante radial zur Drehachse D ausgerichtet (Fig. 3, Fig. 4). Sie können aber auch - siehe Fig. 2 - winklig zur Radialrichtung ausgerichtet sein.According to one variant, the ribs 15 are aligned radially to the axis of rotation D ( 3, 4 ). But you can also - see Fig. 2 - be aligned at an angle to the radial direction.

Der Rippenkörper 14 wird in den Ringraum 12 eingesetzt bzw. eingebaut.The rib body 14 is inserted or installed in the annular space 12.

Vorzugsweise in Drehrichtung (im Uhrzeigersinn; siehe auch Figuren 1) und 2 ) ist jeweils direkt hinter jeder der Rippen 15 und radial außerhalb der Rippen eine bohrungsartige Eintrittsöffnung 17 aus dem Zulaufraum 12 in die Zulaufbohrungen bzw. - kanäle 8 ausgebildet bzw. angeordnet. Die Rippen befinden sich dabei radial innen zu den Eintrittsöffnungen 17.Preferably in the direction of rotation (clockwise; see also Figures 1 ) and 2nd ) a bore-like entry opening 17 is formed or arranged from the inlet space 12 into the inlet bores or channels 8 directly behind each of the ribs 15 and radially outside the ribs. The ribs are located radially inward of the inlet openings 17.

Vorteilhaft ist, dass der Rippenkörper 14 als Ganzes bzw. als ein einziges Element bei der Montage der Schleudertrommel einfachst in den Zulaufraum 12 setzbar ist, wo er drehfest am Verteiler 4 fixiert wird, was z.B. durch Befestigungsmittel wie Schrauben, bajonettartig, durch Schweißen oder dgl. erfolgen kann.It is advantageous that the rib body 14 as a whole or as a single element during the assembly of the centrifugal drum can simply be placed in the inlet space 12, where it is fixed in a rotationally fixed manner on the distributor 4, which e.g. can be done by fasteners such as screws, bayonet-like, by welding or the like.

Durch die vertikale sowie radiale oder in einem Winkelbereich zwischen ±50° zur Radialen R geneigte Ausrichtung der Rippen 15 wird das aus dem Zulaufrohr 7 austretende Produkt auf die Drehgeschwindigkeit der Schleudertrommel 1 beschleunigt und schonend in die Zulaufkanäle 8 des Verteilers 4 geleitet.Due to the vertical and radial orientation of the ribs 15 or inclined at an angle between ± 50 ° to the radial R, the product emerging from the feed pipe 7 is accelerated to the rotational speed of the centrifugal drum 1 and gently guided into the feed channels 8 of the distributor 4.

Ergänzend ist der Zulaufraum 12 derart ausgebildet, dass sich in ihm im Betrieb eine Druckerhöhung gegenüber einer Ausgestaltung ohne Rippenkörper 14 einstellt.In addition, the inlet space 12 is designed in such a way that a pressure increase occurs during operation compared to an embodiment without a rib body 14.

Dies wird nach dem Ausführungsbeispiel der Fig.1 dadurch erreicht, dass das Zulaufrohr 7 einen Scheibenabschnitt 18 (eine "Hydroscheibe") aufweist, der nach Fig. 1 vorteilhaft - aber nicht zwingend - am vertikal unteren Ende des Zulaufrohrs 7 ausgebildet ist, wo er sich vom Zulaufrohr 1 aus senkrecht zur Drehachse D bzw. rechtwinklig zur Axialrichtung des Zulaufrohrs 7 nach außen bis vor die Innenumfangswandung des Verteilers 4 erstreckt. Der verbleibende Spalt ist vorzugsweise kleiner als 10 mm, besonders bevorzugt kleiner als 7 mm. Ein radial nach innen ragende Ansatz 24 am oberen Ende des Verteilers bildet im Betrieb radial nach oben hin einen zusätzlichen Verschluss.This is according to the embodiment of the Fig. 1 achieved in that the inlet pipe 7 has a disc section 18 (a "hydraulic disc") which Fig. 1 Advantageously - but not necessarily - is formed at the vertically lower end of the feed pipe 7, where it extends from the feed pipe 1 perpendicular to the axis of rotation D or at right angles to the axial direction of the feed pipe 7 to the outside of the inner circumferential wall of the distributor 4. The remaining gap is preferably less than 10 mm, particularly preferably less than 7 mm. A radially inwardly projecting extension 24 at the upper end of the distributor forms an additional closure in operation radially upward.

Im Versuch konnte gezeigt werden, dass sich durch den Einbau des Rippenkörpers der Zulaufdruck verringern lässt, z.B. bei 80000 1/h Zulaufleistung um 0,5 bar. Die Zulaufleistung kann entsprechend erhöht werden.The experiment showed that the inlet pressure can be reduced by installing the rib body, e.g. at 80000 1 / h feed capacity by 0.5 bar. The feed rate can be increased accordingly.

Nach Fig. 2 wird ein weitgehend zu Fig.1 analoger Aufbau realisiert, allerdings sind die Rippen 15 hier nicht radial sondern geneigt schräg zur Radialen ausgerichtet, so dass die Rippen mit den jeweiligen Radialen einen Winkel einschließen.To Fig. 2 becomes a largely too Fig. 1 Analog structure realized, but the ribs 15 are not radially aligned but inclined obliquely to the radial, so that the ribs enclose an angle with the respective radial.

Zudem ist der Basisabschnitt 16 konisch geformt, so dass er auf einen entsprechenden konischen Abschnitt 19 des Verteilers aufsetzbar ist, wobei die sich vertikal vom Basisabschnitt nach oben erstreckenden Rippen 15 ebenfalls der konischen Formgebung des Basisabschnitts 16 folgen.In addition, the base section 16 is conically shaped, so that it can be placed on a corresponding conical section 19 of the distributor, the ribs 15 extending vertically upward from the base section likewise following the conical shape of the base section 16.

Der Ringraum 12 ist nach Fig. 2 zumindest in dem Bereich, in welchem die Rippen 4 ausgebildet sind, ebenfalls konisch ausgebildet.The annular space 12 is after Fig. 2 also conical at least in the area in which the ribs 4 are formed.

Oberhalb des Ringraums 12 erstreckt sich ein axialer Rohrabschnitt 20 des Verteilers 4. Dieser Rohrabschnitt 20 ist in seinem oberen vertikalen Bereich, in welchem das Zulaufrohr 7 endet, hier in bevorzugter Ausführung leicht konisch ausgestaltet und in dem sich daran anschließenden unteren Bereich zylindrisch, wobei der Durchmesser in diesem Bereich vorzugsweise dem Durchmesser des Zulaufrohrs 7 entspricht. In dem konischen Bereich ist der Innendurchmesser vorzugsweise nicht mehr als 10 mm, vorzugsweise nicht mehr als 7 mm größer als der äußere Durchmesser des Zulaufrohres 7.Above the annular space 12, an axial pipe section 20 of the distributor 4 extends. This pipe section 20 is in its upper vertical region in which the inlet pipe 7 ends, here in a preferred embodiment slightly conical and cylindrical in the adjoining lower region, the Diameter in this area preferably corresponds to the diameter of the inlet pipe 7. In the conical area, the inner diameter is preferably not more than 10 mm, preferably not more than 7 mm, larger than the outer diameter of the inlet pipe 7.

Das Zulaufrohr 7 erstreckt sich axial wiederum bis in den Einlaufbereich des Verteilers 4.The inlet pipe 7 in turn extends axially into the inlet area of the distributor 4.

Es ist auch wiederum von einem Scheibenabschnitt 18 umgeben. Dieser Scheibenabschnitt 18 ist aber vorzugsweise nicht am freien axialen Ende des Zulaufrohres 7 ausgebildet sondern ein Stück vor dessen axialen Ende.It is also surrounded by a disk section 18. However, this disk section 18 is preferably not formed at the free axial end of the inlet pipe 7, but rather a little in front of it axial end.

Der Scheibenabschnitt 18 erstreckt sich radial in einen Ringraum 21, der sich vertikal oberhalb und unterhalb des Scheibenabschnittes 18 radial über den Außenumfang des Scheibenabschnittes 18 nach Innen erstreckt. Der Ringraum 21 schließt sich vertikal an den Rohrabschnitt 20 des Verteilers an. Hier sind in weiter bevorzugter Ausführung Rippen 23 (vorzugsweise jedenfalls teilweise radial ausgerichtet) am oberen Rand des Ringraumes an einem sich im Betrieb mit dem Verteiler drehfest verbundenen Ring 25 oder einem sonstigen sich im Betrieb drehenden Maschinenteil ausgebildet, welche das Schleudergut im Ringraum in Umfangsrichtung im Betrieb mitnehmen und damit dazu beitragen, dass sich ein radialer Flüssigkeitsspiegel in dem Ringraum 21 ausbilden kann.The disk section 18 extends radially into an annular space 21, which extends vertically above and below the disk section 18 radially over the outer circumference of the disk section 18 inwards. The annular space 21 connects vertically to the pipe section 20 of the distributor. Here, in a further preferred embodiment, ribs 23 (preferably in any case partially radially aligned) are formed on the upper edge of the annular space on a ring 25 which is rotationally fixedly connected to the distributor during operation, or on another machine part which rotates during operation and which in the circumferential direction of the centrifugal material in the annular space Take operation with you and thus help to ensure that a radial liquid level can form in the annular space 21.

An dem Scheibenabschnitt 18 können wiederum vertikale Rippen 22 ausgebildet sein.Vertical ribs 22 can in turn be formed on the disk section 18.

Im Betrieb bildet sich im Ringraum 21 außen ein Flüssigkeitsring aus, der den Zulaufbereich vertikal nach unten hin verschließt.During operation, a liquid ring is formed in the annular space 21 on the outside, which closes the inlet area vertically downwards.

In Kombination mit einem Rippenkörper 14 im Zulaufbereich lässt sich wiederum der Zulaufdruck reduzieren und die Zulaufleistung erhöhen.In combination with a rib body 14 in the inlet area, the inlet pressure can in turn be reduced and the inlet capacity increased.

Die Gefahr einer Verschmutzung des Zulaufbereiches der Schleudertrommel ist zudem besonders niedrig.
