Description

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

Einen gattungsgemäßen Separator zeigt die US 4,729,759 . Einen weiteren bekannten Separator zeigt die DE 10 2004 038 613 A1 .A generic separator shows U.S. 4,729,759 . Another known separator shows DE 10 2004 038 613 A1 .

Ein derartiger Separator hat sich für die Klärung einer Suspension an sich bewährt, soll aber insbesondere in konstruktiver Hinsicht und vorzugsweise auch in seiner Wirksamkeit nochmals weiter optimiert werden.Such a separator has proven itself for the clarification of a suspension, but should be further optimized in particular in terms of construction and preferably also in its effectiveness.

Feststoffphasen werden bislang aus Separatoren auf einem relativ großen Radius der Schleudertrommel abgeleitet, wobei mit diesem Ableiten ein relativ großer Energieverlust erfolgt. Da die Feststoffphase noch relativ gut fließfähig ist, kann es daher sinnvoll sein, diese Phase nicht diskontinuierlich durch Kolbenschieber abzuleiten, sondern beispielsweise durch Düsen am größten Innendurchmesser des Trommelunterteils eine kontinuierliche Ableitung zu ermöglichen. Insgesamt ist hierbei ausgehend von dem gattungsgemäßen Stand der Technik eine energieeffiziente Arbeitsweise un eine gute Reinigbarkeit ein besonderes Ziel bzw. eine besondere Aufgabe.Solid phases have so far been diverted from separators on a relatively large radius of the centrifugal drum, with this diverting a relatively large loss of energy. Since the solid phase is still relatively easy to flow, it can therefore make sense not to discharge this phase discontinuously through piston valves, but rather to enable continuous discharge through nozzles on the largest inner diameter of the lower part of the drum. Overall, based on the generic prior art, an energy-efficient mode of operation and good cleanability is a particular goal or task.

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

Durch die Ableitung der Feststoffphase aus der Schleudertrommel auf einen kleineren inneren Radius wird der Energieverlust beim Ableiten der Feststoffphase verringert. Dabei wird die Feststoffphase üblicherweise aus dem Feststoffraum außerhalb des Tellerpakets nach innen abgeleitet und durch das feststehende Schälorgan und den sich daran anschließenden Feststoffaustrag, der konzentrisch zur Drehachse der Schleudertrommel verläuft, unter verringertem Energieverlust abgeführt.By diverting the solid phase from the centrifugal drum to a smaller inner radius, the energy loss when diverting the solid phase is reduced. The solids phase is usually diverted to the inside from the solids space outside the disk pack and removed through the fixed peeling element and the adjoining solids discharge, which runs concentrically to the axis of rotation of the centrifugal drum, with reduced energy loss.

Um eine Reinigung der Ableitungskammer zu ermöglichen, weist das Schälorgan oder der Feststoffaustrag nahe zur Drehachse oder genau im Bereich der Drehachse eine Durchtrittsöffnung auf, welche die Ableitungskammer, mit dem Inneren des Schälorgans oder des Feststoffaustrags verbindet. Dadurch wird ein Teil des Feststoffstroms durch die Durchtrittsöffnung geleitet und spült den Bereich der Ableitungskammer aus. Somit können Ablagerungen oder Verstopfungen vorteilhaft vermieden werden.In order to enable the discharge chamber to be cleaned, the peeling element or the solids discharge has a passage opening close to the axis of rotation or precisely in the area of the axis of rotation, which connects the discharge chamber with the interior of the peeling element or the solids discharge. This becomes a part of the solids flow is passed through the passage opening and flushes out the area of the discharge chamber. In this way, deposits or blockages can advantageously be avoided.

Der Feststoffaustrag ist bevorzugt als konzentrisch zur Drehachse verlaufendes feststehendes Ableitungsrohr ausgebildet. In einer besonders bevorzugten Ausführungsvariante ist die Durchtrittsöffnung im Bereich zwischen der Drehachse und dem Innenradius des feststehenden Ableitungsrohres angeordnet. Dadurch erreicht der Feststoffstrom beim Rückspülen alle Bereiche in der Ableitungskammer.The solids discharge is preferably designed as a stationary discharge pipe running concentrically to the axis of rotation. In a particularly preferred embodiment variant, the passage opening is arranged in the area between the axis of rotation and the inner radius of the stationary discharge pipe. As a result, the flow of solids reaches all areas in the discharge chamber during backwashing.

Weitere vorteilhafte Ausführungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the invention are the subject of the subclaims.

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

Figur 1
einen vereinfachten Schnitt durch eine Schleudertrommel eines erfindungsgemäßen Separators;
Figur 2
eine Ausschnittsvergrößerung aus Fig. 1.
The invention is described in more detail below with reference to the drawings using an exemplary embodiment. They show:
Figure 1
a simplified section through a centrifugal drum of a separator according to the invention;
Figure 2
an enlarged section Fig. 1 .

Figur 1 zeigt eine vereinfachte Darstellung einer um eine vertikale Drehachse D drehbaren Schleudertrommel 1 eines kontinuierlich betreibbaren Separators. Die Schleudertrommel weist ein Trommelunterteil 2 und ein Trommeloberteil 3 auf, die vorzugsweise in hier nicht dargestellter Weise miteinander verschraubt sind. Derartige Verschraubungen sind dem Fachmann an sich bekannt und bedürfen hier keiner näheren Erörterung. Die Schleudertrommel 1 ist hier ferner innen und außen doppelt konisch ausgebildet. Figure 1 shows a simplified representation of a centrifugal drum 1 rotatable about a vertical axis of rotation D of a continuously operable separator. The centrifugal drum has a lower drum part 2 and an upper drum part 3, which are preferably screwed together in a manner not shown here. Such screw connections are known per se to the person skilled in the art and do not require any further explanation here. The centrifugal drum 1 is also double conical inside and outside.

In der Schleudertrommel 1 ist ein Tellerpaket 4 aus einer Vielzahl von Tellern 5 konzentrisch zur Maschinenachse bzw. zur vertikalen Drehachse D angeordnet. Die Teller 5 weisen eine konische Form auf, sind axial übereinander gestapelt und mittels hier nicht dargestellten Abstandshaltern (Laschen und dgl.) voneinander beabstandet.In the centrifugal drum 1, a set of plates 4 composed of a plurality of plates 5 is arranged concentrically to the machine axis or to the vertical axis of rotation D. The plates 5 have a conical shape, are stacked axially one above the other and are spaced apart from one another by means of spacers (brackets and the like) not shown here.

Das Tellerpaket 4 ist an einem Verteilerschaft 6 eines Verteilers 7 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 4 kann Steigekanäle aufweisen, die aus direkt übereinander liegenden Löchern in den Tellern 5 bestehen und sich über die gesamte Höhe des Tellerpakets 4 erstrecken.The plate pack 4 is held on a distributor shaft 6 of a distributor 7, which is provided on its outer circumference with radially outwardly projecting webs (not visible here) which engage in the plate 3 on the inner circumference. The set of plates 4 can have riser channels which consist of holes in the plates 5 that are directly above one another and extend over the entire height of the set of plates 4.

Ein konzentrisch zur Drehachse D angeordnetes Zulaufrohr 8 ermöglicht die Zuleitung eines Schleudergutes hier beispielhaft von oben in die Schleudertrommel 1 sowie dort durch den Verteilerschaft 6 und durch unterhalb des Tellerpakets 4 im Verteiler 7 ausgebildete Verteilerkanäle 9 in die Schleudertrommel 1.A feed pipe 8 arranged concentrically to the axis of rotation D enables the feed of material to be centrifuged here, for example, from above into the centrifugal drum 1 and there through the distributor shaft 6 and through distributor channels 9 formed below the plate assembly 4 in the distributor 7 into the centrifugal drum 1.

In der Schleudertrommel 1 erfolgt dann kontinuierlich die eigentliche Klärung des zu verarbeitenden Produkts von einer fließfähigen Feststoffphase (z. B. zur Entkeimung) und/oder eine Trennung des Produktes in verschiedene Flüssigkeitsphasen.In the centrifugal drum 1, the actual clarification of the product to be processed from a flowable solid phase (e.g. for sterilization) and / or a separation of the product into different liquid phases then takes place continuously.

Die Flüssigkeitsphase L, wird nach innen hin durch das Tellerpaket 4 und einen oder mehreren Ableitungskanäle in eine Schälkammer 10 und aus dieser mit einer Schälscheibe 12 aus der Trommel abgleitet.The liquid phase L is drained inwards through the disk pack 4 and one or more drainage channels into a peeling chamber 10 and out of this with a peeling disk 12 from the drum.

Zur Ableitung der fließfähigen Feststoffphase S werden keine Feststoffaustragsöffnungen wie Düsen am größten inneren Durchmesser der Schleudertrommel 1 angeordnet, sondern ein Ableitungsrohr 13. Dieses Ableitungsrohr 13 erstreckt sich vorzugsweise radial in der Trommel bis kurz vor den Bereich des größten Innendurchmessers der Schleudertrommel und verläuft von dieser Stelle am Innenumfang der Schleudertrommel radial nach innen bis zu einer Ableitungskammer 14. Das Eintrittsende 26 zum Abgreifen der Feststoffphase liegt in einem Feststoffraum 27 außerhalb des Tellerpakets auf einem Radius R13, welcher größer ist als der größte Radius des Tellerpakets R4. Vorzugsweise liegt das Eintrittsende im radial äußersten Bereich des Feststoffraumes, d.h. in der in Radialrichtung äußeren Hälfte des Feststoffraumes 27.For the discharge of the flowable solid phase S, no solid discharge openings such as nozzles are arranged on the largest inner diameter of the centrifugal drum 1, but a discharge pipe 13 on the inner circumference of the centrifugal drum radially inward up to a discharge chamber 14. The inlet end 26 for tapping off the solid phase lies in a solids space 27 outside the plate assembly on a radius R 13 which is greater than the largest radius of the plate assembly R 4 . The inlet end is preferably in the radially outermost area of the solids space, ie in the outer half of the solids space 27 in the radial direction.

Diese Ableitungskammer 14 ist vorzugsweise zwischen dem Trommelunterteil 3 und dem Verteiler 7 - also unterhalb des Verteilers 7 - ausgebildet, wobei der Spalt zwischen diesen beiden Trommelelementen von einem Ringbauteil 16 verschlossen sein kann. Das Ringbauteil 16 weist vorzugsweise Durchtrittsöffnungen 17 auf, in welche die Ableitungsrohre 13 nach innen hin münden. Der Mittelpunkt der Durchtrittsöffnung ist mit einem Radius R17 von der vertikalen Drehachse beabstandet. In der Ableitungskammer 14 ist wenigstens ein im Betrieb feststehendes, bzw. nicht mit der Schleudertrommel rotierendes Schälorgan 19 angeordnet, welches einen konischen Schälabschnitt 20 mit einer Ableitungsöffnung 21 aufweist, welche nach innen hin in einen Feststoffaustrag in Form eines übergreifenden stillstehenden Ableitungsrohrs 22 mit einem Innenradius R20 mündet, das konzentrisch zur Drehachse D ausgebildet ist und weiter vorzugsweise konzentrisch innerhalb des Zuleitungsrohrs liegt.This discharge chamber 14 is preferably formed between the lower drum part 3 and the distributor 7 - that is, below the distributor 7 - with the gap can be closed by a ring component 16 between these two drum elements. The ring component 16 preferably has passage openings 17 into which the discharge pipes 13 open towards the inside. The center point of the passage opening is spaced from the vertical axis of rotation by a radius R 17 . In the discharge chamber 14 there is at least one peeling element 19, which is stationary or does not rotate with the centrifugal drum, which has a conical peeling section 20 with a discharge opening 21 which leads inwards into a solids discharge in the form of an overlapping stationary discharge pipe 22 with an inner radius R 20 opens, which is designed concentrically to the axis of rotation D and further preferably lies concentrically within the supply pipe.

Aufgrund der sich ausbildenden Druckverhältnisse kann das Produkt vom Außenumfang der Trommel radial nach innen durch das wenigstens eine Ableitungsrohr 13 bis in die Ableitungskammer 14 strömen.Due to the pressure conditions that develop, the product can flow radially inward from the outer circumference of the drum through the at least one discharge pipe 13 into the discharge chamber 14.

Derart erfolgt die Produktableitung durch das innere Ableitungsrohr 13 in die Ableitungskammer 14 und aus dieser mit dem Schälorgan 19 durch das Ableitungsrohr 22 nach außen aus der Schleudertrommel 1 (hier vertikal nach oben aus der Schleudertrommel 1).In this way, the product is diverted through the inner discharge pipe 13 into the discharge chamber 14 and from there with the peeling element 19 through the discharge pipe 22 to the outside of the centrifugal drum 1 (here vertically upwards from the centrifugal drum 1).

Das Schälorgan 19 oder das Ableitungsrohr 22 weist nahe zur Drehachse D oder genau im Bereich der Drehachse D eine Durchtrittsöffnung 23 auf, welche die Ableitungskammer 14, d.h. den Bereich außerhalb des Schälorgans 19 nebst Ableitungsrohr 22 mit dem Inneren des Schälorgans 19 und des Ableitungsrohrs 22 verbindet.The peeling element 19 or the discharge pipe 22 has, close to the axis of rotation D or precisely in the area of the axis of rotation D, a passage opening 23, which the discharge chamber 14, i. connects the area outside the peeling element 19 together with the discharge pipe 22 to the interior of the peeling element 19 and the discharge pipe 22.

Derart strömt zwar ein Teil des durch das Schälorgan 19 abgeleiteten fleißfähigen Feststoffs aus dem Schälorgan 19 zurück in die Ableitungskammer 14. Dies ist von Vorteil, denn das Rückströmen resultiert in einem Reinigen der Ableitungskammer 14. Dieses Reinigen erfolgt einerseits kontinuierlich während des Betriebs des Separators. Insbesondere erfolgt zudem vorzugsweise eine intensive Reinigung in diesem Bereich durch gewählte Anordnung und Geometrie auch bei Reinigungen wie CIP-Reinigungen (Cleaning-In-Place).In this way, part of the hard-working solids diverted by the peeling element 19 flows out of the peeling element 19 back into the discharge chamber 14. This is advantageous because the return flow results in a cleaning of the discharge chamber 14. This cleaning takes place continuously during operation of the separator. In particular, intensive cleaning is also preferably carried out in this area due to the selected arrangement and geometry, even for cleaning such as CIP cleaning (cleaning-in-place).

Insgesamt wird ein energiesparender, hygienischer Separator zur Klärung von Produkten von einer fließfähigen Feststoffphase geschaffen, wie er beispielsweise bei der Klärung von Zitrusfrüchten oder bei der Klärung von Fermentationsbrühen oder dgl. anfallen kann. Dabei ist die Gefahr einer Verschmutzung des Ablaufbereiches der Schleudertrommel - wie vorstehend beschrieben - aufgrund der Reinigungs-/Spülwirkung besonders niedrig.Overall, an energy-saving, hygienic separator is created for the clarification of products from a flowable solid phase, such as can arise, for example, in the clarification of citrus fruits or in the clarification of fermentation broths or the like. The risk of contamination of the drainage area of the centrifugal drum - as described above - is particularly low due to the cleaning / rinsing effect.

Ergänzend kann der Fluss der fließfähigen Feststoffphase durch das Ableitungsrohr 13 durch ein hier nicht dargestelltes Steuer- oder Regelorgan gesteuert oder geregelt werden. Ergänzend können nach einer Alternative auch ergänzende Austrittsdüsen am größten Umfang der Trommel ausgebildet sein.In addition, the flow of the flowable solid phase through the discharge pipe 13 can be controlled or regulated by a control or regulating element not shown here. In addition, according to an alternative, additional outlet nozzles can also be formed on the largest circumference of the drum.
