Abstract

An insulator (14) has a part that closely and radially surrounds a shaft (3) between seal rings (10,11) and an opening (16) to form a small gap (13) through which oil can flow. The seal rings are exposed to the flowing oil to prevent oil from getting to seals.

Description

Die Erfindung betrifft einen Dichtkopf zum Zuführen eines Wärmeträgermediums, insbes. eines Wärmeträgeröls, zu einem rotierenden Drucksystem, wie einer Trockentrommel, Heizwalze oder dergl., bestehend aus einem an das Drucksystem angeschlossenen rohrförmigen Rotor und einem über mittels Fett oder Öl geschmierten Wälzlager auf dem Rotor angeordneten stillstehenden Dichtkopfgehäuse mit mindestens einem Anschlußstutzen für eine das Wärmeträgermedium führende Anschlußleitung, wobei im Inneren des Dichtkopfgehäuses der Rotor in offener Verbindung mit dem Anschlußstutzen steht und axial zwischen dem Anschlußstutzen und den Wälzlagern eine den Rotor gegen die Wand des Dichtkopfgehäuses abdichtende Gleitringdichtung angeordnet ist.The invention relates to a sealing head for supplying a heat transfer medium, esp. A heat transfer oil, to a rotating pressure system, such as a drying drum, heat roller or the like. Comprising a connected to the pressure system tubular rotor and lubricated by means of grease or oil bearings on the rotor arranged stationary sealing head housing with at least one connecting piece for a heat transfer medium leading connecting line, wherein in the interior of the sealing head housing the rotor is in open communication with the connecting piece and axially between the connecting piece and the rolling bearings a rotor against the wall of the sealing head housing sealing mechanical seal is arranged.

Ein derartiger Dichtkopf ist beispielsweise aus der EP 0 448 730 bekannt und hat sich in der Praxis außerordentlich bewährt (siehe auch Dokument DE-C-196 18 661). Zu beachten ist jedoch, daß diese Lösung einen erhöhten Aufwand wegen der Zirkulation eines Vorlagemediums erfordert.Such a sealing head is known, for example, from EP 0 448 730 and has proven extremely successful in practice (see also document DE-C-196 18 661). It should be noted, however, that this solution requires increased expense because of the circulation of a master medium.

Der Erfindung liegt die Aufgabe zugrunde, durch konstruktive Weiterentwicklung einen Dichtkopf der eingangs genannten Art so zu verbessern, daß bei vereinfachtem Aufbau gleichwohl ein Betrieb bei Maximaltemperatur des Wärmeträgermediums ermöglicht wird, ohne daß ein erhöhter Verschleiß insbesondere im Dichtungsbereich auftritt.The invention has for its object to improve by constructive development of a sealing head of the type mentioned so that in a simplified structure nevertheless operation at maximum temperature of the heat transfer medium is made possible without increased wear occurs especially in the sealing area.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die Gleitringdichtung von einem am Dichtkopfgehäuse angeordneten Kühlflansch umschlossen ist, der sich axial beidseits zur Gleitringdichtung erstreckt, und daß an der dem Anschlußstutzen zugewandten Seite der Gleitringdichtung ein den Raum zwischen dem Rotor und dem Dichtkopfgehäuse bis auf einen verbleibenden schmalen Ringspalt abdichtendes Isolierelement vorgesehen ist.This object is achieved according to the invention in that the mechanical seal is surrounded by a sealing head housing arranged on the cooling flange, which extends axially on both sides of the mechanical seal, and that on the connecting piece facing side of the mechanical seal a space between the rotor and the sealing head housing up on a remaining narrow annular gap sealing insulating is provided.

Der durch die Erfindung erreichte Vorteil besteht im wesentlichen darin, daß trotz reduzierter Aufwendungen, wie die Durchführung von einfachen Kühlmaßnahmen sowie die Anbringung eines einfachen Isolierelementes ein sicherer Betrieb bei Maximaltemperatur des Wärmeträgermediums möglich wird, ohne daß Standzeitprobleme an der Dichtung auftreten.The advantage achieved by the invention consists essentially in the fact that despite reduced expenses, such as the implementation of simple cooling measures and the attachment of a simple insulating safe operation at maximum temperature of the heat transfer medium is possible without standstill problems occur at the seal.

In bevorzugter Ausführungsform der Erfindung ist das Isolierelement zweckmäßigerweise als am Dichtkopfgehäuse festgelegtes Hülsenteil gestaltet, wobei die dem Anschlußstutzen zugewandte Seite als radial vorstehender Innenflansch ausgebildet ist, dessen Mantelfläche die Begrenzung des Ringspaltes als Begrenzung zum Motor hin bildet. Auf diese Weise wird zunächst eine deutliche Wärmeisolierung zum Anschlußstutzen hin erreicht.In a preferred embodiment of the invention, the insulating element is expediently designed as a sealing head housing fixed sleeve part, wherein the connecting piece facing side is formed as a radially projecting inner flange, whose lateral surface forms the boundary of the annular gap as a boundary to the engine. In this way, a clear thermal insulation is first achieved to the connection piece out.

Dabei ist es weiter von Vorteil, wenn sich das Isolierelement axial gegen den Kühlflansch abstützt, da somit eine nahtlose Isolierung bis zum Kühlflansch hin erreicht wird. Dazu ist im Rahmen der Erfindung zweckmäßigerweise vorzusehen, daß das Isolierelement aus einem Material von geringer Wärmeleitfähigkeit besteht.It is further advantageous if the insulating member is supported axially against the cooling flange, since thus a seamless insulation is achieved to the cooling flange. For this purpose, it is expedient to provide in the context of the invention that the insulating element consists of a material of low thermal conductivity.

Eine weitere Verminderung der Temperatur im Bereich der Gleitringdichtung wird dadurch erreicht, daß der Kühlflansch eine ringförmige Kühlkammer für ein durchströmendes Kühlmedium aufweist. Hierzu empfiehlt es sich weiter, daß die Kühlkammer mit je einem diametral zueinander angeordneten Zu- bzw. Ablauf versehen ist. Dadurch ist eine vollständige Trennung dieses Kühlkreislaufes gewährleistet, so daß die Kühlung wahlweise mit Schmieröl oder auch lediglich mit Kühlwasser erfolgen kann.A further reduction of the temperature in the region of the mechanical seal is achieved in that the cooling flange has an annular cooling chamber for a flowing cooling medium. For this purpose, it is further recommended that the cooling chamber is provided with a respective diametrically arranged inlet and outlet. This ensures a complete separation of this cooling circuit, so that the cooling can be done either with lubricating oil or only with cooling water.

Darüber hinaus wird im Rahmen der Erfindung vorgeschlagen, daß auf der dem Anschlußstutzen abgewandten Seite der Gleitringdichtung zwischen dem Dichtkopfgehäuse und dem Rotor ein eine geschlossene Kammer bildendes Dichtelement angeordnet ist, wobei in die Kammer ein Befüllstutzen für ein vorzugsweise flüssiges Medium mündet. Diese Kammer kann mit einer geeigneten Flüssigkeit ohne Druck über den Befüllstutzen befüllt werden, wodurch eine chemische Reaktion zwischen dem Luftsauerstoff und der über die Gleitringdichtung übertretenden Ölleckage verhindert wird.In addition, it is proposed in the invention that on the side facing away from the connecting piece side of the mechanical seal between the sealing head housing and the rotor a closed chamber forming sealing element is arranged, wherein in the chamber a filling nozzle for a preferably liquid medium opens. This chamber can be filled with a suitable liquid without pressure via the filling nozzle, whereby a chemical reaction between the oxygen in the air and over the mechanical seal leaking oil leakage is prevented.

Schließlich besteht noch in an sich bekannter Weise die Möglichkeit, eine zusätzliche Isolierung zum Innenraum des Rotors hin in der Weise vorzunehmen, daß der Rotor in dem sich über die Gleitringdichtung bzw. das Dichtungselement und die Lager erstreckenden Bereich doppelwandig ausgebildet ist.Finally, in a manner known per se, it is possible to provide additional insulation to the interior of the rotor in such a way that the rotor is designed to be double-walled in the region extending over the mechanical seal or the sealing element and the bearings.

Der in der Zeichnung dargestellte Dichtkopf 1 dient zum Zuführen eines Wärmeträgermediums, insbesondere eines Wärmeträgeröls, zu einem rotierenden Drucksystem 2, beispielsweise einer Trockentrommel, Heizwalze oder dergleichen, das in der Zeichnung nur mit seiner Anschlußeinrichtung angedeutet ist. Dazu besteht der Dichtkopf 1 aus einem an das Drucksystem 2 angeschlossenen rohrförmigen Rotor 3 und einem über zwei Wälzlager 4 auf dem Rotor 3 angeordneten stillstehenden Dichtkopfgehäuse 5, das einen Anschlußstutzen 6 für eine das Wärmeträgermedium führende, in der Zeichnung nicht näher dargestellte Anschlußleitung besitzt. Im Inneren des Dichtkopfgehäuses 5 steht der Rotor 3 am offenen Rohrende über Öffnungen 7 in unmittelbarer Verbindung mit dem Anschlußstutzen 6, so daß das Wärmeträgermedium durch den Anschlußstutzen 6 und den Rotor 3 in das Drucksystem gelangen kann. Axial zwischen dem Anschlußstutzen 6 und den Wälzlagern 4 ist eine Gleitringdichtung 8 angeordnet, die den Rotor 3 gegen die Wand des Dichtkopfgehäuses 5 abdichtet. Diese Gleitringdichtung 8 besteht vorzugsweise aus einem über einen Faltenbalg 9 am Rotor 3 befestigten Dichtungsring 10 und einem am Dichtkopfgehäuse 5 feststehend angeordneten Dichtungsring 11.The sealing head 1 shown in the drawing is used for supplying a heat transfer medium, in particular a heat transfer oil, to a rotating printing system 2, for example a drying drum, heat roller or the like, which is indicated in the drawing only with its connecting device. For this purpose, the sealing head 1 consists of a connected to the pressure system 2 tubular rotor 3 and a two roller bearings 4 arranged on the rotor 3 stationary sealing head housing 5, which has a connection piece 6 for a heat transfer medium leading, not shown in the drawing connection line. Inside the sealing head housing 5, the rotor 3 is at the open end of the tube via openings 7 in direct communication with the Connecting piece 6, so that the heat transfer medium can pass through the connecting piece 6 and the rotor 3 in the printing system. Axially between the connecting piece 6 and the rolling bearings 4, a mechanical seal 8 is arranged, which seals the rotor 3 against the wall of the sealing head housing 5. This mechanical seal 8 is preferably made of a sealing ring 10 secured to the rotor 3 via a bellows 9 and a sealing ring 11 fixedly arranged on the sealing head housing 5.

Die Gleitringdichtung 8 ist von einem am Dichtkopfgehäuse 5 angeordneten Kühlflansch 12 umschlossen, der sich axial beidseits zur Gleitringdichtung 8 erstreckt.The mechanical seal 8 is enclosed by a cooling flange 12 arranged on the sealing head housing 5, which extends axially on both sides to the mechanical seal 8.

Ferner ist an der dem Anschlußstutzen 6 zugewandten Seite der Gleitringdichtung 8 ein den Raum zwischen dem Rotor 3 und dem Dichtkopfgehäuse 5 bis auf einen verbleibenden schmalen Ringspalt 13 abdichtendes Isolierelement 14 vorgesehen.Further, at the connecting piece 6 facing side of the mechanical seal 8 a the space between the rotor 3 and the sealing head housing 5 to a remaining narrow annular gap 13 sealing insulating 14 is provided.

Das Isolierelement 14 ist im einzelnen als am Dichtkopfgehäuse 5 festgelegtes Hülsenteil gestaltet, wobei die dem Anschlußstutzen 6 zugewandte Seite als radial vorstehender Innenflansch ausgebildet ist. Die innere Mantelfläche dieses Innenflansches bildet die Begrenzung des Ringspaltes 13 zum Rotor 3 hin. Die axiale Höhe dieses Innenflansches beeinflußt dabei die Breite des Ringspaltes 13, wodurch die Zirkulation von Wärmeträgermedium zwischen dem äußeren Bereich der Gleitringdichtung 8 und dem durchströmten Bereich am Anschlußstutzen 6 und den Öffnungen 7 weitgehend unterbunden und somit die Temperatur des Wärmeträgermediums im Dichtungsbereich deutlich reduziert wird. Im übrigen stützt sich das Isolierelement 14 axial gegen den Kühlflansch 12 ab, so daß, da das Isolierelement 14 zweckmäßigerweise aus einem Material geringer Wärmeleitfähigkeit besteht, eine durchgehend wärmeisolierende Wirkung bis hin zum Kühlflansch 12 erreicht wird.The insulating member 14 is designed in detail as fixed to the sealing head housing 5 sleeve part, wherein the connecting piece 6 facing side is formed as a radially projecting inner flange. The inner circumferential surface of this inner flange forms the boundary of the annular gap 13 towards the rotor 3. The axial height of this inner flange affects the width of the annular gap 13, whereby the circulation of heat transfer medium between the outer region of the mechanical seal 8 and the area flowed through at the connecting piece 6 and the openings 7 largely prevented and thus the temperature of the Heat transfer medium in the sealing area is significantly reduced. Moreover, the insulating member 14 is supported axially against the cooling flange 12, so that, since the insulating member 14 is suitably made of a material of low thermal conductivity, a continuous heat-insulating effect is achieved up to the cooling flange 12.

Der Kühlflansch 12 weist, wie sich insbesondere aus der Figur 2 ersehen läßt, eine ringförmige Kühlkammer 15 auf, die von einem Kühlmedium durchströmt wird. Dazu ist die Kühlkammer 15 mit je einem diametral zueinander angeordneten Zu- bzw. Ablauf 16,17 versehen. Als Kühlmedium kann eine Vielzahl jeweils geeigneter Flüssigkeiten zum Einsatz kommen, da dieser Kühlkreislauf in sich abgeschlossen ist, also keine Berührung beispielsweise mit dem Wärmeträgermedium auftreten kann. Insbesondere wird hierfür Schmieröl oder auch einfaches Kühlwasser zur Anwendung kommen.The cooling flange 12 has, as can be seen in particular from Figure 2, an annular cooling chamber 15, which is flowed through by a cooling medium. For this purpose, the cooling chamber 15 is provided with a respective diametrically arranged inlet and outlet 16,17. As a cooling medium, a variety of suitable liquids can be used, since this cooling circuit is self-contained, so no contact can occur, for example, with the heat transfer medium. In particular, lubricating oil or even simple cooling water will be used for this purpose.

Auf der dem Anschlußstutzen 6 abgewandten Seite der Gleitringdichtung 8 ist zwischen dem Dichtkopfgehäuse 5 und dem Rotor 3 ein eine geschlossene Kammer 18 bildendes Dichtelement 19 angeordnet. Diese so gebildete Kammer 18 kann über einen Befüllstutzen 20 mit einem vorzugsweise flüssigen Medium gefüllt werden, wodurch verhindert wird, daß eine chemische Reaktion der über die Gleitringdichtung 8 in diese Kammer 18 gelangenden Ölleckage mit Luftsauerstoff auftreten kann.On the side facing away from the connecting piece 6 of the mechanical seal 8 is a closed chamber 18 forming sealing element 19 is disposed between the sealing head housing 5 and the rotor 3. This thus formed chamber 18 can be filled via a filling nozzle 20 with a preferably liquid medium, thereby preventing that a chemical reaction of reaching over the mechanical seal 8 in this chamber 18 oil leakage can occur with atmospheric oxygen.

Der Rotor 3 ist in dem sich über die Gleitringdichtung 8 bzw. das Dichtungselement 19 und die Lager 4 erstreckenden, mit der Bezugsziffer 21 versehenen Bereich doppelwandig ausgebildet, wodurch ergänzend der Wärmetransport vom Rotor 3 her zur Gleitringdichtung 8 vermindert wird.The rotor 3 is in the over the mechanical seal 8 and the sealing member 19 and the bearing 4 extending, provided with the reference numeral 21 area formed double-walled, which in addition the heat transfer from the rotor 3 ago to the mechanical seal 8 is reduced.
