Description
Die Erfindung betrifft einen Einströmungskopf .. für einen Trockenzylinder einer Papiermaschine, und zwar insbesondere einer solchen, bei der Heiß- wasser für die Trocknung ,der Papierbahn verwendet wird und bei dem in Tragzapfen mit zentralem umlaufendem Einlaßrohr und dieses umgebendem umlaufendem Auslaß vorgesehen ist, an welchen sich mittels einer Abdichtung ein stillstehender Auslaßraum anschließt, der zweckmäßig fest mit einem stillstehenden Zulaufrohr verbunden ist oder bei dem ein Tragzapfen mit zentralem umlaufendem Auslaßrohr und dieses umgebendem umlaufendem Einlaß vorgesehen ist, an welchen sich mittels . einer Abdichtung ein stillstehender Einlaßraum anschließt, der zweckmäßig fest mit einem stillstehenden Auslaßraum verbunden ist. Die bekannten, mit Dampf betriebenen Einrichtungen dieser Gattung haben jedoch den Nachteil; daß wenigstens zwei Abdichtungen notwendig sind, und zwar eine zwischen der Außenluft und dem Auslaß-bzw. Einlaßraum und eine zwischen diesem Raum und dem Zulauf- bzw. Ablaufrohr.The invention relates to an inflow head .. for a drying cylinder of a paper machine, in particular one in which hot water is used for drying the paper web and in which there is provided in support pins with a central circumferential inlet pipe and surrounding outlet which by means of a seal is followed by a stationary outlet space, which is expediently firmly connected to a stationary inlet pipe or in which a support pin with a central circumferential outlet pipe and surrounding inlet is provided, to which by means of. a seal is connected to a stationary inlet space, which is expediently firmly connected to a stationary outlet space. However, the known, steam-operated devices of this type have the disadvantage; that at least two seals are necessary, namely one between the outside air and the outlet or. Inlet space and one between this space and the inlet and outlet pipe, respectively.
Dieser Nachteil soll durch den Gegenstand der Erfindung behoben werden, der dadurch gekennzeichnet ist, daß das feststehende Zulaufrohr in das umlaufende Einlaßröhr innerhalb desAuslaßraumes oder eines damit verbundenen, unter dem Auslaßdruck stehenden Raumes einmündet, wobei in dem Zulaufrbhr an der Einmündungsstelle zweckmäßig eine Verengung vorgesehen ist.` Die eingangs an zweiter Stelle genannte Bauart wird dadurch verbessert, daß der feststehende Auslaßraum in das umlaufende Auslaßrohr innerhalb des Einlaßraumes oder eines mit diesem verbundenen und unter dessen Druck stehenden Raums einmündet, wobei in dem Auslaßröhr an der Einmündungsstelle zweckmäßig eine Erweiterung vorgesehen ist.This disadvantage is to be remedied by the subject matter of the invention, which is characterized in that the fixed inlet pipe in the circumferential Inlet tube within the outlet space, or one connected thereto, under the outlet pressure standing room opens, being expedient in the inlet pipe at the junction a narrowing is provided. 'The type mentioned in the second place is improved by the fact that the fixed outlet space in the circumferential outlet pipe within the inlet space or one connected to it and under its pressure standing room opens, in which case expedient in the outlet tube at the junction point an extension is planned.
Dadurch ergibt sich der Vorteil, daß die statischen Wasserdrücke auf beiden Seiten dieser Einmündungsstelle einander annähernd gleich werden, so daß an dieser Stelle keine Abdichtung mehr notwendig ist und man sich hier mit einer Labyrinthdichtung begnügen kann.This has the advantage that the static water pressures on both sides of this junction are approximately equal to each other, so that At this point no more sealing is necessary and you are here with a Labyrinth seal can be satisfied.
Die Erfindung sei an Hand der Zeichnung, in der in Fig. i und 2 zwei Ausführungsbeispiele des Erfindungsgegenstandes im Längsschnitt dargestellt sind, näher erläutert.The invention is based on the drawing, in Fig. I and 2 two Embodiments of the subject matter of the invention are shown in longitudinal section, explained in more detail.
Nach Fig. i ist der Trockenzylinder i mit seinem hohlen Tragzapfen 2 in einem Wälzlagerblock 3 gelagert. In diesem Tragzapfen ist mittels Bolzen q ein Innenrohr 4 befestigt. Eine Abdichtung 6 trennt den zentralen Einlaß durch das Innenrohr 4 von dem ringförmigen Auslaß durch den Tragzapfen 2. An den umlaufenden Tragzapfen 2 schließt sich unter Zwischenschaltung einer Abdichtung 8 die stillstehende Auslaßkammer 7 an. An das umlaufende Innenrohr 4 schließt sich unter Zwischenschaltung einer Labyrinthdichtung io die still-.stehende Zulaufleitung 9 an. An der Stelle der Labyrinthdichtung -weist die Zulaufleitung 9 eine Verjüngung i i auf, in der eine Geschwindigkeitssteigerung und demzufolge eine Herabsetzung des statischen Druckes erfolgt, derart, daß dieser Druck etwa dem in der Auslaßkammer 7 'herrschenden Druck gleich wird. Das aus den Teilen 9 und 7 zusarümengestellte Stück wird von außenliegenden Federn 12 nach links gedrückt, so daß bei 8 eine gute Abdichtung gewährleistet ist.According to Fig. I, the drying cylinder i is with its hollow support pin 2 stored in a roller bearing block 3. In this trunnion is by means of bolts q an inner tube 4 attached. A seal 6 separates the central inlet through the Inner tube 4 from the annular outlet through the support pin 2. To the circumferential Trunnion 2 closes with the interposition of a seal 8, the stationary Outlet chamber 7. The circumferential inner tube 4 is connected with the interposition a labyrinth seal io the stationary supply line 9. At the point the labyrinth seal, the inlet line 9 has a taper i i in which an increase in speed and consequently a decrease in the static Pressure takes place in such a way that this pressure is approximately that prevailing in the outlet chamber 7 ' Pressure will be the same. The piece made up of parts 9 and 7 is from external springs 12 pressed to the left, so that at 8 a good seal is guaranteed.
Selbstverständlich sind die Rollen des Ein- und Auslasses vertauschbar, wie Fig.2 erkennen läßt. Diese unterscheidet sich von Fig. i hauptsächlich nur in der aus den Pfeilen hervorgehenden Strömungsrichtung. 2' ist also hier das Einlaßrohr, das Auslaßrohr, 7' der Einlaßraum und g das Ablaufrohr. An der Stelle i i' ist jetzt keine Verjüngung, sondern eine Erweiterung vorgesehen, um -die erwünschte Erhöhung des statischen Auslaßdruckes bis auf den Wert des statischen Einlaßdruckes zu erreichen.Of course, the roles of the inlet and outlet are interchangeable, as Fig.2 shows. This differs from Fig. I mainly only in the direction of flow indicated by the arrows. 2 'is the inlet pipe here, the outlet pipe, 7 'the inlet space and g the drain pipe. At the point i i 'is now no rejuvenation, but an extension provided in order to increase the desired height of the static outlet pressure up to the value of the static inlet pressure.
