Description

Separator mit vertikaler Drehachse  Separator with vertical axis of rotation

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

Ein derartiger Separator ist aus der DE 10 2004 038 613 Al 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, Tankum- Schaltungen 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 known from DE 10 2004 038 613 Al. As described in this document, it may come in a use of separators for the sterilization of milk u.U. too short-term deterioration of the sterilization efficiency due to pressure increases in the inlet, the z. B. caused by partial discharges, Tankum- circuits or by an increased air content in the product. Another problem is the transport (shaft run) of germs to the peeling disk.

Zur Lösung dieses Problems wird in der gattungsgemäßen DE 10 2004 038 613 Al 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 Entlüftung s werte erzielbar sind. Diese Lösung hat sich an sich bewährt, soll aber insbesondere in konstruktiver Hinsicht und vorzugsweise auch Hinsicht ihrer Wirksamkeit nochmals weiter optimiert werden. To solve this problem is proposed in the generic DE 10 2004 038 613 Al that connecting holes to an annulus, which is formed above the free end of the inlet pipe in the manifold, are provided that extend the connection holes between a preferably conical inlet space and the annulus , and that the outlet openings from the inlet space in the inlet bores of the distributor and the connecting bores to the annular space is assigned in each case a rib. As a result, a particularly uniform acceptance and acceleration as well as a particularly uniform ventilation of the product is achieved, whereby even with increased air content in the product relatively constant ventilation s values are achieved. This solution has proven itself, but should be further optimized especially in terms of design and preferably also their effectiveness.

Die Lösung dieses Problems ist die Aufgabe der Erfindung. The solution to this problem is 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 schonende- re Produktzuführung im Verteiler. Zudem wird die Gefahr, dass sich im Zulaufbereich Ablagerungen bilden, verringert. The ribbed body is easy to assemble. In addition, the inlet pressure can be reduced and the feed rate increased. This results in a gentle re product feed in the distributor. In addition, the risk of deposits forming in the inlet area is reduced.

Vorzugsweise ist eine oder sind mehrere der Drehachse ausgerichtet, was eine star- ke Beschleunigung des Schleudergutes in Umfang srichtung bedeutet. Es ist aber auch denkbar, sie relativ zur jeweiligen Radialen anzustellen, beispielsweise zwischen 1° und 80°. Die Rippen können gerade, aber auch gebogen ausgebildet sein. Denkbar ist auch eine schaufelartige Auslegung mit Krümmungen in allen Raumrichtungen, solange eine Beschleunigungswirkung in Umfang srichtung gegeben ist. Preferably, one or more of the axis of rotation is aligned, which means a strong acceleration of the material to be centrifuged in the circumferential direction. But it is also conceivable to make them relative to the respective radial, for example, between 1 ° and 80 °. The ribs may be straight, but also curved. It is also conceivable a blade-like design with curvatures in all directions, as long as an acceleration effect in the circumferential direction is given.

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: The invention will be described in more detail below with reference to the drawings with reference to an exemplary embodiment. Show it:

Figur 1 einen vereinfachten Schnitt durch eine Schleudertrommel eines erfin- dungsgemäßen Separators; 1 shows a simplified section through a centrifugal drum of a separator according to the invention;

Figur 2 einen vereinfachten Schnitt durch einen Teilbereich einer weiteren  2 shows a simplified section through a portion of another

Schleudertrommel; und  Centrifugal drum; and

Fig. 3, 4 jeweils perspektivische Ansichten von Rippenkörpern.  Fig. 3, 4 are each perspective views of rib bodies.

Figur 1 zeigt eine vereinfachte Darstellung eines Teilbereichs einer um eine Drehachse D drehbaren Schleudertrommel 1 eines kontinuierlich betreibbaren Separa- tors, 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. FIG. 1 shows a simplified representation of a partial region of a centrifugal drum 1 of a continuously operable separator rotatable about a rotation axis D, in which a plate package 2 of a multiplicity of plates 3 is arranged concentrically to the machine axis or axis of rotation D. The centrifugal drum is here twice conically formed 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 by means of spacers, not shown here (tabs and the like.) Distance from each other.

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 package 2 is held on a distributor shaft 4 of a distributor 5, which is provided on its outer periphery with radially outwardly projecting webs (here not visible), which engage on the inner circumference of the plate 3 in this. The plate package 2 has riser channels 6, which consist of directly superimposed holes in the plates 3 and extend over the entire height of the plate package 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. An inlet pipe 7 lying concentrically to the machine axis makes it possible to feed a centrifuged material from above into the centrifugal drum 1 and through the distributor shaft 4 and below the plate package 2 in the distributor 5 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 o- der mehrere Ableitungen 9, ggf. auf verschiedenen Durchmessern, z.B. durchThe actual clarification of the product to be processed by solids (for example for sterilization) and / or a separation of the product into different liquid phases, which take place through one or more outlets 9, if necessary at different diameters, then takes place continuously in the centrifugal drum 1 , eg by

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. Peeling discs (not shown here) and solid discharge openings 10 are derived from the centrifugal drum 1. Here, the solids discharge openings 10 are 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 supply pipe 7, which is stationary in operation, to the distributor 4 rotating in operation, i. from the non-rotating system to the rotating system during operation.

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 supplied through the inlet pipe 7 first enters from the inlet pipe 7 into an inlet chamber 12 in the center of the distributor shaft 4, the free lower outlet of the inlet pipe 7 extending below the upper edge of the inlet chamber 12.

Die Verteilerkanäle 8 setzen in der Umfangswand 13 des Zulaufrohres an. The distribution channels 8 begin 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 feed chamber 12 is designed according to FIG. 1 such that a ribbed body 14 with one or preferably a plurality of ribs 15 can be inserted into it. The ribbed bodies 14 are rotatably connected to the centrifugal drum, preferably with the distributor 4, connected.

Beispielhaft sind zwei geeignete Rippenkörper 14 in Fig. 3 und 4 dargestellt. By way of example, two suitable ribbed bodies 14 are shown in FIGS. 3 and 4.

Die dargestellten Rippenkörper 14 weisen jeweils einen Basisabschnitt 16 auf. Dieser Basisabschnitt 16 ist vorzugsweise als umfangsgeschlossener Ringabschnitt ausgebildet (Fig. 1 ', Fig. T). 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.l erstreckt er sich vertikal, nach Fig. 2 ist der Basisabschnitt 16 dagegen konisch ausgebildet. Der Basisabschnitt 16 wird jeweils mit dem drehenden System, insbesondere mit dem Verteiler 4, drehfest verbunden. The illustrated ribbed bodies 14 each have a base portion 16. This base portion 16 is preferably formed as a circumferentially closed ring portion (Fig. 1 ', Fig. T). According to Figures 3 and 4, the annular base portions 16 are flat, so that they extend in the installed state perpendicular to the axis of rotation D, according to Fig.l it extends vertically, according to Fig. 2, the base portion 16, however, is conical. The base portion 16 is rotatably connected respectively to the rotating system, in particular to the distributor 4.

Die Form des Basisabschnitts 16 entspricht jeweils vorzugsweise der Formgebung des Verteilers 4 in einem entsprechenden Anlage- bzw. Auflagebereich. The shape of the base portion 16 preferably corresponds in each case 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. Of the annular base portion 16, the ribs 15 project vertically vertically and when installed, they are also vertically aligned.

Die Basisabschnitte 16 der Ausführungsbeispiele der Fig. 3 und 4 werden vorzugs- weise vertikal nach unten hin ausgerichtet, so dass die Rippen 15 vertikal nach oben in den Zulaufraum 12 ragen. The base sections 16 of the exemplary embodiments of FIGS. 3 and 4 are preferably oriented 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 RippenThe ribs 15 of the embodiments are formed integrally with the base portion 16 and project from one axial side thereof vertically. The ribs 15 are formed circumferentially distributed on the base body 16. The radial length of the ribs

15 entspricht vorzugsweise zumindest der vertikalen Höhe der Eintrittsöffnungen 17 in die Verteilerkanäle 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. Der Rippenkörper 14 wird in den Ringraum 12 eingesetzt bzw. eingebaut. 15 preferably corresponds at least to the vertical height of the inlet openings 17 in the distributor channels 8. The ribs 15 are aligned according to a variant radially to the axis of rotation D (Fig. 3, Fig. 4). But you can also - see Fig. 2 - be aligned at an angle to the radial direction. The ribbed body 14 is inserted or installed in the annular space 12.

Vorzugsweise in Drehrichtung (im Uhrzeigersinn; siehe auch Figur 3) 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 FIG. 3), a bore-like inlet opening 17 from the inlet chamber 12 into the inlet bores or channels 8 is formed or arranged directly behind each of the ribs 15 and radially outside the ribs. The ribs are located radially inward to the inlet openings 17th

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 Scheißen oder dgl. erfolgen kann. It is advantageous that the rib body 14 as a whole or as a single element in the assembly of the centrifugal drum is easily settable in the inlet chamber 12, where it is fixed in rotation against the distributor 4, which is e.g. by fastening means such as screws, bayonet-like, by shitting or the like. Can be done.

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 aus- tretende Produkt auf die Drehgeschwindigkeit der Schleudertrommel 1 beschleunigt und schonend in die Zulaufkanäle 8 des Verteilers 4 geleitet. As a result of the orientation of the ribs 15, which is inclined vertically and radially or at an angle of ± 50 ° to the radial R, the product emerging from the feed tube 7 is accelerated to the rotational speed of the centrifugal drum 1 and gently guided into the inlet 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 chamber 12 is designed such that it adjusts a pressure increase in relation to a configuration without ribbed body 14 in operation.

Dies wird nach dem Ausführungsbeispiel der Fig.l dadurch erreicht, dass das Zu- laufrohr 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 Innenum- fangswandung 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. Im Versuch konnte gezeigt werden, dass sich durch den Einbau des Rippenkörpers der Zulaufdruck verringern lässt, z.B. bei 80000 l/h Zulaufleistung um 0,5 bar. Die Zulaufleistung kann entsprechend erhöht werden. Nach Fig. 2 wird ein weitgehend zu Fig.l 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. This is achieved according to the exemplary embodiment of FIG. 1 in that the inlet pipe 7 has a disk section 18 (a "hydro disk") which, according to FIG. 1, is advantageously - but not necessarily - formed at the vertically lower end of the inlet pipe 7, where it extends from the inlet pipe 1 perpendicular to the axis of rotation D or perpendicular to the axial direction of the inlet pipe 7 outwardly to the inner circumferential wall of the distributor 4. The remaining gap is preferably less than 10 mm, more preferably less than 7 mm radially inwardly projecting lug 24 at the upper end of the distributor forms an additional closure in operation radially upwards. In the experiment it could be shown that the inlet pressure can be reduced by installing the ribbed body, eg at 80000 l / h feed rate by 0.5 bar. The feed rate can be increased accordingly. According to Fig. 2, a largely similar to Fig.l structure is realized, however, the ribs 15 are not radially aligned here but inclined obliquely to the radial, so that the ribs with the respective radial enclosing an angle.

Zudem ist der Basisabschnitt 16 konisch geformt, so dass er auf einen entsprechen- den 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 portion 16 is conically shaped so that it can be placed on a corresponding conical portion 19 of the manifold, wherein the ribs 15 extending vertically upwards from the base portion also follow the conical shape of the base portion 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 also formed conically according to Fig. 2, at least in the region 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 derAbove the annular space 12 extends an axial pipe section 20 of the distributor 4. This pipe section 20 is in its upper vertical region in which the inlet pipe 7 terminates, here in a preferred embodiment slightly conical and cylindrical in the adjoining lower portion, wherein the

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. Diameter in this area preferably corresponds to the diameter of the inlet pipe 7. In the conical region, the inner diameter is preferably not more than 10 mm, preferably not more than 7 mm, larger than the outer diameter of the feed pipe 7.

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

Es ist auch wiederum von einem Scheibenabschnitt 18 umgeben. Dieser Scheiben- abschnitt 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 in front of its axial end.

Der Scheibenabschnitt 18 erstreckt sich radial in einen Ringraum 21, der sich vertikal oberhalb und unterhalb des Scheibenabschnittes 18 radial über den Außenum- fang 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 Umfang srichtung im Betrieb mitnehmen und damit dazu beitragen, dass sich ein radialer Flüssigkeitsspiegel in dem Ringraum 21 ausbilden kann. An dem Scheibenabschnitt 18 können wiederum vertikale Rippen 22 ausgebildet sein. The disk portion 18 extends radially into an annular space 21 which extends vertically above and below the disk portion 18 radially over the outer circumference. fang of the disc portion 18 extends inwardly. The annular space 21 connects vertically to the pipe section 20 of the distributor. Here are in a further preferred embodiment, ribs 23 (preferably at least partially aligned radially) at the upper edge of the annular space on a rotatably connected in operation with the distributor ring 25 or other rotating in operation machine part, which in the annular space in the circumference of the centrifuged material take in operation and thus help that a radial fluid level can form in the annular space 21. In turn, vertical ribs 22 may be formed on the disc section 18.

Im Betrieb bildet sich im Ringraum 18 außen ein Flüssigkeitsring aus, der den Zulaufbereich vertikal nach unten hin verschließt. In operation, a liquid ring forms in the annular space 18 on the outside, which closes the inlet area vertically downwards.

In Kombination mit einem Rippenkörper 14 im Zulaufbereich lässt sich wiederum der Zulauf druck reduzieren und die Zulaufleistung erhöhen. In combination with a ribbed body 14 in the inlet area can in turn reduce the inlet pressure and increase the inlet capacity.

Die Gefahr einer Verschmutzung des Zulaufbereiches der Schleudertrommel ist zudem besonders niedrig. The risk of contamination of the inlet area of the centrifugal drum is also particularly low.
