Description

Selbstentleerender Separator mit Tellerpaket Self-draining separator with disc package
Die Erfindung betrifft einen selbstentleerenden Separator mit Tellerpaket nach dem Oberbegriff des Anspruchs 1.The invention relates to a self-draining separator with disc package according to the preamble of claim 1.
Selbstentleerende Separatoren mit Tellerpaketen, die beispielsweise zur Entleerung einen Kolbenschieber oder dgl. aufweisen, sind an sich in verschiedensten Ausfüh¬ rungsformen bekannt. Sie werden in verschiedenen Arten von Zentrifugen, so z.B. in Klär-, Trenn- oder Entkeimungszentrifugen für verschiedenste Zwecke eingesetzt. Bevorzugtes Anmeldungsgebiet ist dabei die Verarbeitung von Milchprodukten und hier insbesondere die Entkeimung und die Entrahmung von Milch.Self-emptying separators with disk packs which, for example, have a piston slide or the like for emptying, are known per se in a wide variety of embodiments. They are used in different types of centrifuges, e.g. Used in clarifying, separating or sterilizing centrifuges for a variety of purposes. The preferred area of application is the processing of dairy products and in particular the sterilization and skimming of milk.
Es ist auch bekannt, selbstentleerende Zentrifugentrommeln mit Rippen außerhalb des Tellerpakets zu versehen. Eine derartige Anordnung zeigt beispielsweise die US 2,126,864, die einen Separator mit einer Trommel mit Feststoffaustragsöffnungen zeigt, welche von einem Kolbenschieber verschließbar sind.It is also known to provide self-emptying centrifuge drums with ribs outside the plate pack. Such an arrangement is shown, for example, in US Pat. No. 2,126,864, which shows a separator with a drum with solids discharge openings, which can be closed by a piston slide.
Bei den heute üblichen selbstentleerenden Separatoren treten in der Praxis u.U. Reini¬ gungsprobleme auf. Es zeigt sich, dass der Reinigungseffekt am Trommeldeckel und am Boden des Schleuderraumes in der Trommel besonders problematisch ist und dass dort nach einer automatischen Reinigung oftmals noch Verschmutzungen aufgefunden werden können.In today's usual self-cleaning separators u.U. Cleaning problems on. It turns out that the cleaning effect on the drum cover and on the bottom of the centrifugal space in the drum is particularly problematic and that there is often still contamination to be found after an automatic cleaning.
Vor diesem Hintergrund hat die Erfindung die Aufgabe, den konstruktiven Aufbau des Separators auf gattungsgemäße Art derart zu verbessern, dass eine verbesserte Reinigungswirkung erzielbar ist.Against this background, the invention has the object to improve the structural design of the separator in the generic way such that an improved cleaning effect can be achieved.
Die Erfindung löst diese Aufgabe durch den Gegenstand des Anspruches 1. Nach der Erfindung weist die Trommel Feststoffaustragsöffhungen auf und der Ab¬ stand zwischen den Rippen - bzw. dem vorteilhaft realisierten Rippeneinsatz - und der Innenwandung der Trommel beträgt an jeder Stelle mindestens drei Millimeter.The invention solves this problem by the subject matter of claim 1. According to the invention, the drum has Feststoffaustragsöffhungen and the Ab¬ stood between the ribs - or the advantageous realized rib insert - and the inner wall of the drum is at least three millimeters at each point.
Damit wird ein derart großer Abstand zwischen den Rippen und dem Innenmantel der Trommel realisiert, dass im Feststoffraum an jeder Stelle ausreichend große Abstände zwischen den Rippen und dem Trommelinnenmantel, insbesondere dem Trommelde¬ ckel und dem Boden des Schleuderraums sowie vorzugsweise zu sonstigen hinsicht¬ lich der Reinigung kritischen Stellen bestehen, wodurch an der äußeren Umfangsflä- che und in anderen Randbereichen des Schleuderraumes stets eine genügend große Relativbewegung der Flüssigkeit gegenüber der Trommel in Umfangsrichtung zuge¬ lassen wird.Thus, such a large distance between the ribs and the inner shell of the drum is realized that in the solid space at any point sufficiently large distances between the ribs and the drum inner shell, in particular the Trommelde¬ ckel and the bottom of the centrifugal space and preferably to other hinsicht¬ Lich the Cleaning critical points exist, which is on the outer peripheral surface and in other peripheral regions of the centrifugal space always sufficient relative movement of the liquid relative to the drum in the circumferential direction zuge¬ is allowed.
Zum Stand der Technik werden noch die DE 567 665, die DE 444,573, die US 2,662,687 und die US 2,313,541 genannt. Diese Schriften zeigen jeweils Kammerse¬ paratoren mit Rippeneinsätzen außerhalb der Tellerpakte, aber keine Feststoffaus- tragsöffnungen, so dass sich die erfindungsgemäßen Vorteile nicht ergeben können. Die US 2,477,982 zeigt einen selbstentleerenden Separator mit Austrittsöffnungen ohne Kolbenschieber, wobei sich Rippen außerhalb der Tellerpakets wiederum bis an den Trommeldeckel erstrecken. Die US 5,735,789 zeigt einen Separator mit einem Tellerpaket mit rippenförmigen Abstandshaltern.The prior art still DE 567 665, DE 444.573, US 2,662,687 and US 2,313,541 called. These documents each show Kammerse¬ parators with rib inserts outside the disk pacts, but no solid discharge openings, so that the advantages of the invention can not arise. The US 2,477,982 shows a self-draining separator with outlet openings without spool, with ribs outside the plate package in turn extend to the drum lid. US 5,735,789 shows a separator with a disk package with rib-shaped spacers.
Vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous developments and refinements of the invention can be found in the dependent claims.
Vorzugsweise wird zwischen den Rippen und dem Tellerpaket ein Ringspalt von mindestens 0,5 mm, maximal aber 5 mm ausgebildet, um auch diesen Bereich genü¬ gend zu reinigen.Preferably, an annular gap of at least 0.5 mm, but not more than 5 mm, is formed between the ribs and the plate pack in order to sufficiently clean this region as well.
Nach einer weiteren Ausgestaltung der Erfindung ist es vorteilhaft, wenn die Rippen mindestens 5 Prozent aber maximal 95 Prozent der Querschnittsfläche des Feststoffraumes abdecken, um stets eine genügend große Reinigungswirkung sicherzustellen. Bei einer Auslegung als Trennseparator ist es nach der Erkenntnis der Erfindung fer¬ ner vorteilhaft, wenn der Außendurchmesser der Rippen mindestens 1 mm, maximal aber 25 mm größer ist als der Durchmesser des Scheidetellers.According to a further embodiment of the invention, it is advantageous if the ribs cover at least 5 percent but not more than 95 percent of the cross-sectional area of the solids space in order to always ensure a sufficiently large cleaning effect. In a design as Trennseparator it is according to the invention of the invention fer¬ ner advantageous if the outer diameter of the ribs at least 1 mm, but at most 25 mm larger than the diameter of the separator plate.
Hierbei sollte der Schwerpunkt der Rippenfläche vorzugsweise oberhalb der Entlee¬ rungsebene liegen. Alternativ ist es auch denkbar, diesen Schwerpunkt unterhalb der Entleerungsebene anzuordnen, was aber zu weniger vorteilhaften Ergebnissen führt.In this case, the center of gravity of the rib surface should preferably be above the drainage level. Alternatively, it is also conceivable to arrange this center of gravity below the emptying level, but this leads to less advantageous results.
Nach einer weiteren vorteilhaften Weiterbildung der Erfindung sind die Rippenflä¬ chen mit Ausgleichsöffnungen versehen. Diese entlasten die Rippen bei Trommelent¬ leerungen in vorteilhafter Weise von Spitzen des Coriolisdruckes.According to a further advantageous development of the invention, the rib surfaces are provided with compensation openings. These relieve the ribs in Trommelent¬ emptying advantageously of tips of the Coriolisdruckes.
Es ist ferner vorteilhaft, die Rippen so zu positionieren, dass ihre Flächen jeweils in einem Winkel von bis zu 45° voreilend oder nacheilend zum Radius der Trommel ausgerichtet sind.It is also advantageous to position the ribs so that their surfaces are each aligned at an angle of up to 45 ° leading or trailing to the radius of the drum.
Nach Weiterbildung der Erfindung ist es zudem denkbar, anstelle von ebenen Rippen dreidimensional gekrümmte Schaufeln einzusetzen.After development of the invention, it is also conceivable to use three-dimensionally curved blades instead of flat ribs.
Schließlich hat es sich gezeigt, dass wenigstens zwei, vorzugsweise aber 8 bis 24 Rip¬ pen, insbesondere gleichmäßig am Außenumfang des Tellerpakets verteilt werden sollten.Finally, it has been shown that at least two, but preferably 8 to 24 ribs should be distributed in particular uniformly on the outer circumference of the plate package.
Vorteilhaft werden die Rippen durch Verbindungselemente zu einem ringförmigen Einsatz zusammengefaßt, was die Montage und Demontage der Rippen als Einheit erleichtert.Advantageously, the ribs are combined by connecting elements to form an annular insert, which facilitates the assembly and disassembly of the ribs as a unit.
Dieser Rippeneinsatz wird zudem vorzugsweise durch Stützelemente, die in das Tel¬ lerpaket integriert sind, in seiner Position fixiert.This rib insert is also preferably fixed in position by support elements which are integrated in the telescope package.
Ergänzend wird der Rippeneinsatz zur Fixierung vorzugsweise fest mit dem Scheideteller - wenn vorhanden - verbunden. Nachfolgend wird die Erfindung unter Bezug auf die Figuren anhand bevorzugter Ausführungsbeispiele näher beschrieben. Es zeigt:In addition, the rib insert for fixing is preferably firmly connected to the separator plate - if present. The invention will be described in more detail below with reference to the figures with reference to preferred embodiments. It shows:

Draufsicht.Top view.
Figur 1 zeigt eine stark schematisiert dargestellte Trommel 1 für einen ansonsten nicht hinsichtlich seiner übrigen Komponenten wie dem Antrieb u.dgl. dargestellten Sepa¬ rator mit vertikaler Drehachse D, wobei die Trommel einen Schleuderraum 2 um¬ grenzt, in den ein Tellerpaket 3 aus einer Mehrzahl konischer Teller 4 eingesetzt ist, in denen ein oder mehrere Steigekanäle 5 ausgebildet sind.Figure 1 shows a highly schematic illustrated drum 1 for an otherwise not with regard to its other components such as the drive and the like. shown separator with a vertical axis of rotation D, wherein the drum um¬ a centrifugal space 2 borders, in which a plate package 3 of a plurality of conical plate 4 is inserted, in which one or more riser channels 5 are formed.
An dieser Stelle sei angemerkt, dass die Begriffe wie „oben", „unten", „vorne" oder „hinten" u.dgl. sich lediglich auf die dargestellten schematisieren Ausführungsbeispie¬ le beziehen und nicht einschränkend zu verstehen sind. So kann das Zulaufrohr bei Alternativen, hier nicht dargestellte Ausführungsform, auch von unten her in die Trommel geführt sein, obwohl in Figur 1 eine Variante dargestellt ist, bei welcher das Zulaufrohr von oben in die Trommel geführt ist.It should be noted that the terms such as "top", "bottom", "front" or "rear" and the like. refer only to the illustrated schematic examples and are not to be understood as limiting. Thus, the inlet pipe in alternatives, not shown embodiment, also be guided from below into the drum, although in Figure 1, a variant is shown, in which the inlet pipe is guided from above into the drum.
Das zentrische Zulaufrohr 6 mündet von hier zunächst von oben her in einen Verteiler 7, der Kanäle 8 aufweist, welche das Schleudergut nach außen bis zu Austrittsöffnun¬ gen 9 in den Schleuderraum 2 leiten.The centric inlet pipe 6 opens from here initially from above into a distributor 7, which has channels 8, which conduct the material to be centrifuged outwards as far as exit openings 9 into the centrifuging space 2.
Die Austrittsöffnungen 9 können auf verschiedenen Radien angeordnet werden, vor¬ zugsweise auf solchen Radien, welche kurz vor bzw. innerhalb oder nach bzw. außer¬ halb des Außenumfanges der Teller 4 liegen. Die Trommel weist Feststoffaustragsöffnungen 10 auf, die vorzugsweise am größten Durchmesser der Trommel liegen und denen vorzugsweise ein Kolbenschieber (hier nicht dargestellt) vorgeschaltet ist. Zur Realisierung der Selbstentleerungsfunktion bzw. zum Öffnen und Schließen der Feststoffaustragsöffnungen 10 kann z.B. ein hier nicht dargestellter Kolbenschieber dienen.The outlet openings 9 can be arranged at different radii, preferably on those radii which lie shortly before or within or after or outside the outer circumference of the plates 4. The drum has Feststoffaustragsöffnungen 10, which are preferably at the largest diameter of the drum and which preferably a piston slide (not shown) is connected upstream. To realize the self-emptying function or to open and close the solids discharge openings 10 can serve, for example, a not shown here spool.
Wenigstens ein Ableitungskanal 11, dem eine Schälscheibe nachgeschaltet sein kann, ermöglicht das Ableiten einer Flüssigkeitsphase aus dem Schleuderraum 2.At least one discharge channel 11, which may be followed by a paring disc, allows the discharge of a liquid phase from the centrifugal space 2.
Nach dem Ausführungsbeispiel der Figur 2, welches vereinfacht dargestellt ist, so dass das Zulaufrohr und die Kanäle und Austrittsöffnungen des Verteilers nicht darge¬ stellt sind, ist es noch möglich, eine zweite Flüssigkeitsphase über einen Scheideteller 23 (Außendurchmesser Ds) aus der Trommel abzuleiten.According to the embodiment of Figure 2, which is shown in simplified form, so that the inlet pipe and the channels and outlet openings of the manifold are not darge, it is still possible to derive a second liquid phase via a separator plate 23 (outer diameter Ds) from the drum.
Die Trommel 1 weist ein Trommelunterteil 12 und ein Trommeloberteil 13 auf, die über einen Verschlußring 14 o.dgl. fest miteinander verbunden sind.The drum 1 has a drum base 12 and a drum shell 13, or the like via a locking ring 14. are firmly connected.
Außerhalb des Tellerpakets ist in dem sich radial nach außen verjüngenden Ring¬ bzw. Feststoffraum 15 ein Rippeneinsatz 16 (siehe Figur 8) mit mehreren Rippen 17 angeordnet, wobei die Rippen 17 durch Verbindungselemente 18, 19 zu dem Einsatz 16 zusammengefaßt sind.Outside the plate package, a rib insert 16 (see FIG. 8) with a plurality of ribs 17 is arranged in the radially outwardly tapering ring or solid space 15, the ribs 17 being joined to the insert 16 by connecting elements 18, 19.
Der Einsatz kann durch Stützelemente, die in das Tellerpaket integriert sind (hier nicht dargestellt), in seiner Position fixiert werden. Auch der Einsatz ist an jeder Stelle mindestens 3 mm von der Trommelinnenwandung beabstandetThe insert can be fixed in its position by supporting elements that are integrated in the plate package (not shown here). Also, the insert is spaced at any position at least 3 mm from the drum inner wall
Alternativ ist es auch denkbar, den Rippeneinsatz 16 zur Fixierung fest mit dem Scheideteller 23 der Figur 2 zu verbinden.Alternatively, it is also conceivable to firmly connect the rib insert 16 for fixing with the divider plate 23 of FIG.
Wichtig ist, dass der Rippeneinsatz 16 im Feststoffraum 15 fest in seiner Lage fixiert ist. Die Rippen können dabei - wie in Figur 8 erkennbar - radial nach außen gerichtet sein oder aber in Hinsicht auf die Drehrichtung (R)- siehe Figur 7 - insbesondere bis zu 45° geneigt zur Radialen r (Winkel α) voreilend oder nacheilend ausgerichtet sein.It is important that the rib insert 16 is firmly fixed in the solid space 15 in its position. As can be seen in FIG. 8, the ribs can be directed radially outwards or, with regard to the direction of rotation (R) - see FIG. 7 - in particular up to 45 ° inclined to the radial r (angle α) can be aligned leading or lagging.
Wichtig ist nun, dass an den Außenkanten der Rippen 17 und dem Trommelunterteil 12 bzw. dem Trommeloberteil 13 jeweils ein Spalt Sl, S2 verbleibt, der ringsum an jeder Rippe mindestens 3 mm oder mehr breit ist. Vorzugsweise besteht ferner zwi¬ schen den Rippen und dem Tellerpaket ein weiterer Ringspalt S3 von mindestens 0,5 mm und maximal 5 mm Breite.It is now important that at the outer edges of the ribs 17 and the drum base 12 and the drum shell 13 each have a gap Sl, S2 remains which is all around at least 3 mm or more wide at each rib. Furthermore, there is preferably between the ribs and the plate package, a further annular gap S3 of at least 0.5 mm and a maximum of 5 mm in width.
Derart wird eine besonders vorteilhafte Reinigungswirkung erzielt, denn es wird sichergestellt, dass stets eine genügend große Reinigungswirkung im Feststoffraum 15 erzielt wird, da an allen Stellen zwischen den Rippen 17 und der Trommel 1 stets eine genügend große Strömung an kritischen Stellen besteht und insbesondere an der äuße¬ ren Umfangsflächen in allen Randbereichen des Schleuderraumes eine genügend gro¬ ße Relativbewegung der Flüssigkeit gegenüber der Trommel in Umfangsrichtung zu¬ gelassen wird.Such a particularly advantageous cleaning effect is achieved because it is ensured that always a sufficiently large cleaning effect in the solid space 15 is achieved because at all points between the ribs 17 and the drum 1 is always a sufficiently large flow at critical points and in particular at the On the outer peripheral surfaces in all peripheral regions of the centrifugal space, a relatively large relative movement of the fluid relative to the drum in the circumferential direction is allowed.
Figur 1 zeigt eine Variante, bei welcher die Rippen 17 einen Großteil des Querschnitts des Feststoffraumes, insbesondere bis zu 95 Prozent des Querschnitts des Feststoff¬ raums 15 abdecken.FIG. 1 shows a variant in which the ribs 17 cover a large part of the cross section of the solids space, in particular up to 95 percent of the cross section of the solids space 15.
Der Querschnitt der Rippen 17 in Figur 2 ist dagegen etwas kleiner, wobei in Figur 2 auch noch der ergänzende Scheideteller 23 vorgesehen ist. Der Außendurchmesser DA der Rippen ist mindestens 2 mm und maximal 25 mm größer als der Durchmesser D5 des Scheidetellers 23.The cross-section of the ribs 17 in Figure 2, however, is slightly smaller, in Figure 2 also the additional cutting plate 23 is provided. The outer diameter D A of the ribs is at least 2 mm and a maximum of 25 mm larger than the diameter D 5 of the separator plate 23rd
Figur 3 veranschaulicht, dass der Schwerpunkt Pl der Rippenflächen oberhalb deren Wirkungsebene liegt, die durch die Feststoffaustragsöffnung 10 bestimmt ist.FIG. 3 illustrates that the center of gravity Pl of the rib surfaces lies above its plane of action, which is determined by the solids discharge opening 10.
Figur 4 veranschaulicht eine entsprechende Variante, bei der dieser Schwerpunkt P2 der Rippen unterhalb der Ebene der Feststoffaustragsöffnung 10 angeordnet ist. Figur 5 veranschaulicht weitere Verbindungselemente (z.B. Ringe) 20, 21 zur Verbin¬ dung der Rippen 17 untereinander.FIG. 4 illustrates a corresponding variant in which this center of gravity P2 of the ribs is arranged below the plane of the solids discharge opening 10. FIG. 5 illustrates further connecting elements (eg rings) 20, 21 for connecting the ribs 17 to one another.
Figur 6 zeigt, dass die Rippen mit Öffnungen 22 versehen sein können, um die Rip¬ penflächen der Rippen 17 am Feststoffaustrag von Spitzen des Coriolisdruckes zu ent¬ lasten. FIG. 6 shows that the ribs can be provided with openings 22 in order to relieve the rib areas 17 of the ribs 17 at the solids discharge of peaks of the Coriolis pressure.
