Description

Zentrifuge mit einer mit einem Trenntellerpaket versehenen Trommel Centrifuge with a drum provided with a separator plate package
Die Erfindung betrifft eine Zentrifuge, insbesondere einen Separator, mit einer Trom- mel nach dem Oberbegriff des Anspruchs 1.The invention relates to a centrifuge, in particular a separator, with a drum according to the preamble of claim 1.
Derartige Separatoren sind an sich seit langem bekannt. Zum Stand der Technik seien insofern die DE 36 20 548 Al, die GB 728 822 A, die FR 13 59 356 A und die DE 654 319 Al genannt.Such separators have been known for a long time. In this respect, DE 36 20 548 A1, GB 728 822 A, FR 13 59 356 A and DE 654 319 A1 are known from the state of the art.
Verbesserungsbedarf besteht nach wie vor in Hinsicht auf die Art und Weise der Zuleitung des Schleudergutes in das Trenntellerpaket, und zwar insbesondere dann, wenn die Zentrifuge derart gestaltet ist, dass das Schleudergut in der Trommel radial von außen in das Trenntellerpaket strömt.There is still a need for improvement with regard to the manner in which the product to be centrifuged is fed into the separator plate package, in particular when the centrifuge is designed in such a way that the product to be centrifuged flows radially from the outside into the separator plate package.
Aus der DE 654 319 A ist es bekannt, in einem Tellerpakt in den einzelnen Trenntellern in einem äußeren Umfangsrandbereich, der horizontal ausgerichtet ist, jeweils Ausprägungen auszubilden, welche im Zusammenspielen in axialer Richtung eine Art Steigekanal ausbilden.From DE 654 319 A, it is known, in a disc pact in the individual separation plates in an outer peripheral edge region, which is aligned horizontally, each forms forms, which form a kind of rising channel in the axial direction together.
Aus der US 25 99 619 A ist es bekannt, am Außenumfang des Tellerpakets wenigstens rohrartige Elemente zu verteilen, die radial nach Innen hin offen sind und nach außen hin einzelne axial versetzte Schlitze aufweisen, so dass Feststoff nach außen hin austreten kann. Diese Kanäle sind in das Trommelunterteil integriert, was wenig praktisch und im Betrieb instabil ist.From US 25 99 619 A it is known to distribute on the outer circumference of the plate package at least tubular elements which are radially inwardly open and outwardly have individual axially offset slots, so that solid material can escape to the outside. These channels are integrated into the drum base, which is less practical and unstable during operation.
Die Erfindung hat ausgehend von dem gattungsgemäßen Stand der Technik die Aufgabe, die Zuleitung des zu verarbeitenden Schleudergutes in das Tellerpaket in der Trommel zu optimieren.Starting from the generic state of the art, the invention has the task of optimizing the supply of the material to be processed into the disk package in the drum.
Die Erfindung löst diese Aufgabe durch den Gegenstand des Anspruchs und den Gegenstand des Anspruchs 17. Danach sind am Außenumfang des Tellerpakets wenigstens eines oder mehrere rohrartige Elemente angeordnet, so dass auf einfache Weise eine steigekanalähnliche Zuleitung des zu verarbeitenden Produktes in das Trenntellerpaket erfolgt, und zwar nach einer möglichen - aber nicht zwingenden - Variante über dessen gesamte axiale Höhe verteilt. Es sind ferner die rohrartigen Elemente außen am Trenntellerpaket befestigt.The invention solves this problem by the subject matter of the claim and the subject matter of claim 17. Thereafter, at least one or more tubular elements are arranged on the outer circumference of the plate package, so that in a simple manner a rising channel-like supply of the product to be processed in the Trenntellerpaket, namely distributed over a possible - but not mandatory - variant over its entire axial height. Furthermore, the tubular elements are attached to the outside of the separator plate package.
Derart wird die Zuleitung des Schleudergutes in die Trommel und in das Trenntellerpaket optimiert. Die Anordnung ist auch bei hohen Drehzahlen sicher und stabil. Zudem ist sie im Gegensatz zum gattungsgemäßen Stand der Technik leicht herstellbar.In this way, the supply of the material to be centrifuged is optimized in the drum and in the Trenntellerpaket. The arrangement is safe and stable even at high speeds. In addition, it is easy to produce in contrast to the generic state of the art.
Der Begriff der rohrartigen Elemente ist nicht zu eng zu fassen. Er umfasst insbesondere verschiedenste Formen nicht umfangsgeschlossener Rohre oder Rinnen. Besonders vorteilhaft ist eine halbzylindrische rinnenartige Form, wobei die offene Seite dieser Rinnen radial nach innen hin gerichtet wird. Die Rinnen können einen halbkreisförmigen Querschnitt aber beispielsweise auch einen abgeflachten oder winkligen Querschnitt aufweisen.The concept of tubular elements is not too narrow. In particular, it comprises a wide variety of shapes of non-circumferentially closed pipes or gutters. Particularly advantageous is a semi-cylindrical groove-like shape, wherein the open side of these grooves is directed radially inward. The grooves may have a semicircular cross-section but also, for example, a flattened or angled cross-section.
Die Erfindung schafft auch den Gegenstand des nebengeordneten und selbstständig für sich - aber auch in Weiterbildung des Anspruchs 1- erfinderischen Anspruchs 17, nach dem auch bereits eine optimierte Einleitung des zu verarbeitenden Produktes in den Trenntellerstapel in der Trommel erreicht wird. Eine besonders vorteilhafte Produktzuführung wird erreicht, wenn eines der Alternativen dieses Anspruchs mit den rohrartigen Elementen kombiniert wird.The invention also provides the subject matter of the independent and self-contained - but also in development of claim 1- inventive claim 17, after which an optimized introduction of the product to be processed is already achieved in the separation plate stack in the drum. A particularly advantageous product delivery is achieved when one of the alternatives of this claim is combined with the tubular elements.
Vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous embodiments of the invention can be found in the dependent claims.
Nachfolgend wird die Erfindung unter Bezug auf die Zeichnung Anhang von Ausführungsbeispielen näher beschrieben. Es zeigt:The invention will be described in more detail below with reference to the drawing appendix of exemplary embodiments. It shows:

Figur 4 eine Schnittansicht eines Teilbereiches einer vierten Separatortrommel.Figure 4 is a sectional view of a portion of a fourth separator drum.
Figur 1 und 3 zeigen einen Teilbereich eines Unterteils einer für einen kontinuierlichen Betrieb ausgelegten Trommel 1 mit vertikaler Drehachse D einer hier in bevorzugter Ausgestaltung als Separator ausgebildeten Zentrifuge.Figures 1 and 3 show a portion of a lower part of a designed for continuous operation drum 1 with a vertical axis of rotation D of a trained here in a preferred embodiment as a separator centrifuge.
Die Trommel 1 weist vorzugsweise sowohl einen einfach oder doppelt konischen In- nenmantel als auch einen einfach oder doppelt konischen Außenmantel auf. DieThe drum 1 preferably has both a single or double conical inner jacket and a single or double conical outer jacket. The
Trommel 1 ist hier mehrteilig ausgebildet und weist einen Trommelverschlussring 24 auf, der ein Trommelunterteil Ia und ein Trommeloberteil Ib der Trommel 1 zusammenhält.Drum 1 is here designed in several parts and has a drum lock ring 24, which holds a drum base Ia and a drum shell Ib of the drum 1 together.
Die Trommel 1 weist ein Zulaufrohr 2 auf, welches in einen Verteiler 3 mündet, der einen ersten rohrartigen Abschnitt 4 und einen sich daran anschließenden, sich konisch aufweitenden Abschnitt 5 aufweist.The drum 1 has a feed pipe 2, which opens into a distributor 3, which has a first tubular section 4 and an adjoining, conically widening section 5.
Der Abschnitt 5 ist umfangsverteilt mit sich hier relativ zur vertikalen Drehachse D in radialer Richtung schräg nach unten sowie außen erstreckenden Verteilerkanälen 6 versehen, die hier in besonders bevorzugter Ausgestaltung rohrförmig zylindrisch ausgebildet sind.The section 5 is circumferentially distributed with here relative to the vertical axis of rotation D in the radial direction obliquely downward and outwardly extending distribution channels 6 are provided, which are formed here in a particularly preferred embodiment tubular cylindrical.
Auf dem Verteiler 3 ist ein Tellerpaket 7 aus Trenntellern 8 (trennend und/oder klä- rend wirkend) angeordnet, zwischen denen jeweils ein Abstandsspalt ausgebildet ist, dessen Höhe von Laschen 9 bestimmt wird.Disposed on the distributor 3 is a disc pack 7 of separating discs 8 (separating and / or clarifying acting), between each of which a spacing gap is formed, the height of which is determined by tabs 9.
Die Trommel 1 weist wenigstens einen oder mehrere FlüssigkeitsauslaßΛlässe wie z.B. Schälscheiben auf (hier nicht dargestellt) sowie umfangsverteilt im Bereich des größ- ten Durchmessers der innen vorzugsweise einfach oder doppelt konischen Trommel 1 Feststoffaustragsöffhungen 10, die hier mit Hilfe eines vorzugsweise fluidbetätigten Kolbenschiebers 11 in der Trommel 1 geöffnet und verschlossen werden können, um eine Feststoffphase aus der Trommel auszutragen. Der Kolbenschieber 11 wird vorzugsweise hydraulisch betätigt, wozu ein Hydrauliksystem mit einer Steuerwasserzuleitungsbohrung 21, einem Steuerventil 23, einer Steuerwasserableitungsbohrung 22 und/oder eine Steuerwasserzuführung 25 vorgesehen sein können.The drum 1 has at least one or more FlüssigkeitsauslaßΛlässe such as peeling discs on (not shown here) and circumferentially distributed in the region of the largest diameter of the inside preferably single or double conical drum 1 Feststoffaustragsöffhungen 10 here by means of a preferably fluid-operated spool 11 in the Drum 1 can be opened and closed to discharge a solid phase from the drum. The piston valve 11 is preferably actuated hydraulically, for which purpose a hydraulic system with a pilot water supply bore 21, a control valve 23, a control water drainage bore 22 and / or a control water supply 25 may be provided.
In die Trommel 1 zu leitendes Schleudergut wird durch das Zulaufrohr 2 und die Verteilerkanäle 6 um den unteren äußeren Rand 12 des Verteilers herum in das Tellerpaket bzw. die Spalte zwischen den Trenntellern geleitet.Into the drum 1 to be conveyed centrifugal material is passed through the inlet pipe 2 and the distribution channels 6 around the lower outer edge 12 of the distributor around in the plate package or the gap between the separator plates.
Vorzugsweise sind jeweils unterhalb des Mündungsbereiches jedes Verteilerkanals 6 rinnenartige Vertiefungen als Umlenkungsbereiche 13 in der zum Trommelinnenraum bzw. Tellerpaket 7 gewandten Fläche des Kolbenschiebers 11 ausgebildet, die sich von diesem Bereich wiederum vorzugsweise radial etwas - z.B. einige wenige Zentimeter - bis über den äußeren Umfang des Tellerpakets 7 radial hinaus erstrecken und in ihrem Endbereich derart konvex ausgebildet sind, dass sie einen durch die Verteilerkanä- Ie 6 in die Trommel 1 geleiteten Produktstrom parallel zur Drehachse D radial außerhalb des größten Umfangs des Trenntellerpakets 7 axial nach oben hin in rohrartige Elemente 14 umlenken.Preferably groove-like depressions are formed as deflecting regions 13 in the surface facing towards the drum interior or plate package 7 of the piston slide 11 respectively below the mouth region of each distributor channel 6, which in turn preferably radially from this region something -. a few centimeters - to extend radially beyond the outer periphery of the plate package 7 and are formed in its end portion so convex that they pass through the Verteilerkanä- Ie 6 in the drum 1 product flow parallel to the axis of rotation D radially outside the largest circumference of the separator plate package 7 deflect axially upward into tubular elements 14.
Die rohrartigen Elemente 14 schließen sich vorzugsweise unmittelbar radial nach au- ßen hin an den äußeren Umfang des Trenntellerpakets 7 an und verlaufen parallel zur Drehachse der Trommel 1.The tube-like elements 14 preferably adjoin the outer circumference of the separator plate pack 7 directly radially outwards and run parallel to the axis of rotation of the drum 1.
Bei Entleerungen wird der Kolbenschieber nach unten bewegt, wohingegen die rohr- förmigen Elemente 14 am Trenntellerstapel verbleiben. Die rohrförmigen Elemente bilden eine Rinne aus, die aus einem durchgehenden axialen Stück (Fig. 1) oder aber aus mehreren axial aneinander gesetzten Abschnitten bestehen kann (Fig. 3)When emptying the spool is moved down, whereas the tubular elements 14 remain on the separator plate stack. The tubular elements form a channel, which may consist of a continuous axial piece (FIG. 1) or of a plurality of axially abutting portions (FIG. 3).
Die rohrförmigen Elemente 14 ragen hier radial in den Feststoffraum 20.The tubular elements 14 protrude radially into the solid space 20 here.
Es ist auch denkbar, dass der Verteiler 5 - siehe Fig. 4 - selbst so ausgebildet wird, dass in ihm eine Umlenkung im letzten Abschnitt vor seiner Austrittsöffnung nach oben in die rohrförmigen Elemente 14 erfolgt, wobei dann z.B. im Verteiler selbst einer Art Umlenkungsbereich 13' nach Art einer rinnenförmigen Vertiefung ausgebildet sein kann. Eine derartige Ausgestaltung wäre insbesondere sinnvoll, wenn die Trom- mel keinen Kolbenschieber aufweist sondern beispielsweise Düsen als Feststoffaus- tragsöffhungen, durch welche eine kontinuierliche Entleerung einer Feststoffphase erfolgen kann.It is also conceivable that the distributor 5 - see Fig. 4 - itself is formed so that in it a deflection in the last section upstream of its outlet opening into the tubular elements 14 takes place, in which case, for example, in the distributor itself a kind of deflection 13th 'may be formed in the manner of a groove-shaped depression. Such an embodiment would be particularly useful if the mel has no piston valve but, for example, nozzles as solids discharge openings, through which a continuous emptying of a solid phase can take place.
Die Trennteller 8 sind - siehe Fig. 2 - durch die radialen Laschen 9 voneinander ge- trennt und bilden übereinander gelegt Tellerspalte. Die rohrförmigen Elemente 14 liegen vorzugsweise - bezogen auf die Drehrichtung der Trommel - innerhalb von zwei Laschen jeweils unmittelbar hinter den Laschen 9.The separating plates 8 are - see Fig. 2 - separated by the radial tabs 9 from each other and form superimposed plate column. The tubular elements 14 are preferably - in relation to the direction of rotation of the drum - within two tabs immediately behind the tabs. 9
Die rohrförmigen Elemente 14 sind vorzugsweise nicht umfangsgeschlossen ausgebil- det, sondern weisen radial in der Trommel 1 jeweils nach innen hin einen sich axial erstreckenden Spalt bzw. offenen Bereich (siehe Fig. 2) 15 auf, durch den das zu verarbeitende Schleudergut radial nach innen hin in das Tellerpaket 7 eintreten kann.The tubular elements 14 are preferably not formed circumferentially closed, but have radially in the drum 1 inwardly towards an axially extending gap or open area (see Fig. 2) 15, through which the material to be processed centrifuged radially inward can enter into the plate package 7.
Vorzugsweise sind die rohrartigen Elemente 14 ferner an ihrem in der Trommel radial weiter außen liegenden Bereich mit axial beabstandeten Öffnungen 16 versehen, die in ihrem Zusammenspiel eine perforationsartige Struktur ausbilden. Durch diese Öffnungen 16 kann sich abscheidender Feststoff aus dem rohrartigen Element in den Feststoffraum 20 gelangen.Preferably, the tubular elements 14 are further provided at its in the drum radially further outwardly region with axially spaced openings 16 which form a perforation-like structure in their interaction. By means of these openings 16, precipitating solids can pass from the tubular element into the solids space 20.
Die rohrartigen Elemente 14 können sich — müssen sich aber nicht - in vertikaler Richtung über die gesamte Höhe des Trenntellerpakets erstrecken.The tubular elements 14 may - but need not extend - in the vertical direction over the entire height of the separator plate package.
Die rohrartigen Elemente 14 erlauben eine besonders gleichmäßige Verteilung und Zuleitung des zu verarbeitenden Produktes in das Trenntellerpaket 7. Es ist daher be- sonders vorteilhaft, wenn jedem der Verteilerkanäle 6 jeweils eines der rohrartigen Elemente 14 und eine Umlenkrinne 13 zugeordnet ist.The tubular elements 14 allow a particularly uniform distribution and supply of the product to be processed in the Trenntellerpaket 7. It is therefore particularly advantageous if each of the distribution channels 6 each one of the tubular elements 14 and a deflection channel 13 is assigned.
Vorzugsweise werden die rohrartigen Elemente außen am Trenntellerpaket 7 befestigt, beispielsweise an einem oder mehreren Haltetellern 19, die jeweils in einem vorgege- benen axialen Abstand zueinander zwischen die Trennteller 8 des Trenntellerpakets 7 gesetzt sind. Die rohrartigen Elemente 14 können die Halteteller 19 auch nur durchsetzen und in ihnen z.B. formschlüssig geführt sein, wobei die rohrartigen Elemente dann vorzugsweise an wenigstens einer Stelle, z.B. am untersten Halteteller verschweißt werden. Diese Art der Anordnung der rohrförmigen Elemente 14 ist besonders ein- fach und montagefreundlich, da die Anzahl notwendiger Verbindungen zwischen den Trenntellern und dem rohrformigen Element auf nur einen einzigen Bereich beschränkt wird.The tubular elements are preferably fastened on the outside of the separator plate package 7, for example on one or more holding plates 19, which are each set at a predetermined axial distance between the separating plates 8 of the separator plate package 7. The tubular elements 14 can only pass through the holding plate 19 and be guided in them, for example, form-fitting manner, wherein the tubular elements are then preferably welded to at least one point, eg at the lowest holding plate. This type of arrangement of the tubular elements 14 is particularly easy and easy to install, since the number of necessary connections between the separator plates and the rohrformigen element is limited to only a single area.
Die Halteteller 19 können jeweils im Abstand einer gewissen Anzahl von Trenntellern 8 im Tellerpaket 7 angeordnet sein, so dass sie einerseits die Funktion eines „normalen" Trenntellers erfüllen können und darüber hinaus mit den Laschen 17 bzw. Halterungen versehen sind.The holding plates 19 can each be arranged at a distance of a certain number of separation plates 8 in the plate package 7, so that they can fulfill the function of a "normal" separation plate on the one hand and are also provided with the tabs 17 and brackets.
.Die Halteteller 19 können an ihrem äußeren Umfang mit ringartigen Ansätzen / TeI- lerlaschen 17 versehen sein, welche von den rohrartigen Elementen 14 vorzugsweise formschlüssig durchsetzt sind..The holding plates 19 may be provided on their outer circumference with ring-like projections / partial lugs 17, which are preferably penetrated by the tubular elements 14 in a form-fitting manner.
Derart werden die rohrartigen Elemente 14 auf einfache Weise in der Trommel gehalten.Thus, the tubular members 14 are easily held in the drum.
Es ist denkbar, die rohrformigen Elemente 14 mit dem Trenntellerstapel 7 z.B. an einer Stelle, insbesondere an einem Halteteller ergänzend oder alternativ zu verbinden.It is conceivable to connect the tube-shaped elements 14 with the separator plate stack 7, e.g. at one point, in particular on a retaining plate supplementary or alternatively to connect.
Es ist auch denkbar, die rohrformigen Elemente ergänzend am Verteiler zu befestigen.It is also conceivable to attach the rohrformigen elements complementary to the manifold.
Die rohrformigen Elemente 14 können einstückig, aber auch mehrstückig ausgebildet sein.The rohrformigen elements 14 may be integrally formed, but also in several pieces.
So ist es beispielsweise auch denkbar, ein rohrförmiges Element aus mehreren rippen- artigen Blechen zusammenzusetzen oder ein rohrförmiges Element dadurch auszubilden, dass beispielsweise zwei rippenförmige Bleche nach Art eines V oder L angeordnet werden. Ebenfalls ist die Form eines U oder Halbkreises möglich.For example, it is also conceivable to assemble a tubular element from a plurality of rib-like metal sheets or to form a tubular element in that, for example, two rib-shaped metal sheets are arranged in the manner of a V or L. Also, the shape of a U or semicircle is possible.
Wenn das rohrförmige Element mehrstückig ausgebildet ist, so sind die einzelnen E- lemente 14a, b, c, ... jeweils an einem der Halteteller befestigt. Auch ein axialer Überlapp der Elemente 14a, b, ... wäre bei entsprechender Ausgestaltung denkbar.If the tubular element is formed in several pieces, then the individual elements 14a, b, c, ... are each fastened to one of the retaining plates. An axial overlap of the elements 14a, b, ... would be conceivable with appropriate design.
Durch Wahl einer geeigneten Anzahl von Trenntellern zwischen den Haltetellern 19 ergibt sich wieder eine weitgehend geschlossene Rinne außen am Tellerpaket. Die verbleibenden Spalte 26 sind vernachlässigbar hinsichtlich der Wirkung des rohrartigen Elements 14By selecting a suitable number of separation plates between the holding plates 19 again results in a largely closed channel outside the plate package. The remaining gaps 26 are negligible with regard to the effect of the tubular element 14
Eine Anordnung nach Art eines L setzt im Grunde voraus, dass der Grundschenkel derart angeordnet wird, dass das aus dem Verteilerkanal 6 jeweils austretende Produkt von diesem Grundschenkel in Umfangsrichtung bzw. in Drehrichtung mitgenommen wird (Fig. 2b). Der zweite Schenkel verschließt den Weg radial in den Feststoffraum.An arrangement in the manner of an L basically requires that the base leg is arranged in such a way that the product emerging from the distribution channel 6 is taken along by this base limb in the circumferential direction or in the direction of rotation (FIG. 2b). The second leg closes the path radially into the solids space.
Die rohrartigen Elemente können auch radial etwas nach innen in die Tellerpakete hineinragen, beispielsweise, wenn diese an ihrem Außenumfang Aussparungen aufwei- sen, welche eine Art Rinne am Außenumfang des Trenntellerstapels ausbilden (hier nicht dargestellt), in welche die Ränder der rohrartigen Elemente 14 eingreifen. The tube-like elements can also protrude slightly radially inwardly into the plate packs, for example if they have recesses on their outer circumference, which form a kind of groove on the outer circumference of the separator plate stack (not shown here), in which the edges of the tube-like elements 14 engage ,
