Description
Drehbarer Trockenzylinder für Papier-, Textil- und ähnliche Maschinen Die Leistung der dampfgeheizten drehbaren Trockenzylinder für I-'apier-,*Textilinaschinen u. dgl. wird bei hoher Umfangsgeschwindigkeit dadurch erheblich beeinträchtigt, daß das im Innern des Zylinder: sich ansammelnde Kondenswasser durch die Schleuderwirkung nach außen getrieben wird und infolgedessen eine die Innenseite des Zylindermantels in gewisser Höhe vollständig bedeckende wärmeisolierende Schicht bildet, die den Übertritt der Wärme des in das Innere des Zylinders eingeführten Heizdampfes in den Zylinderniantel erschwert.Rotatable drying cylinder for paper, textile and similar machines The performance of the steam-heated rotating drying cylinder for paper and textile machines and the like is significantly impaired at high circumferential speed, that the inside of the cylinder: accumulating condensation water due to the centrifugal effect is driven to the outside and as a result the inside of the cylinder jacket to a certain extent completely covering the heat-insulating layer that forms the The heat of the heating steam introduced into the interior of the cylinder passes into complicates the cylinder measure.
Gemäß der Erfindung wird dieser Übelstand dadurch beseitigt. daß man an der Innenfläche des Zvlinderniantels vorgesehene Rippen, wie sie an sich bei Hohlwalzen für Kalander bekannt sind, in ihrer radialen Höhe in bezug auf die Mündung des in den Hohlzylinder ragenden lUires zur Ableitung des Kondenswassers so bemißt. daß der Abstand der Rohrmündung von der Drehachse des Zylinders größer ist als der Radius der Innenflächen der Rippen. Dadurch wird erreicht, daß die Rippen auf alle Fälle mindestens teilweise aus der beim Umlaufen des Zylinders an dessen innerer Mantelfläche haftenden hondensatschicht herausragen und dadurch das Heizmittel an den betreffenden Stellen finit dem Metall des Zylindermantels in unmittelbare Berührung bringen.According to the invention, this drawback is thereby eliminated. that he ribs provided on the inner surface of the Zvlindeniantel, as they are in Hollow rolls for calenders are known in their radial height with respect to the mouth of the lUires protruding into the hollow cylinder for draining off the condensation water. that the distance of the muzzle from the axis of rotation of the cylinder is greater than that Radius of the inner surfaces of the ribs. This ensures that the ribs on all Cases at least partially from the rotation of the cylinder on its interior The surface of the adhesive layer of condensate protrudes and thereby the heating agent the points concerned are in direct contact with the metal of the cylinder jacket bring.
In der Zeichnung, die die Erfindung in mehreren Ausführungsformen beispielsweise veranschaulicht, zeigt Abb. i einen Trockenzylinder im Längsschnitt. bei dem die zylincirische llantelinnenfläche i derart mit ringsum laufenden Rippen oder andersartig gestalteten Erhöhungen a versehen ist, daß der sich infolge der Schleuderwirkung zwischen ihnen bildende Wasserring 3 einen Teil der Rippen oder Erhöhungen 2 frei läßt. so daß diese mit dem im Innern des Zylinders befindlichen Heizdampf in unmittelbarer Berührung stehen. Dazu ist es erforderlich, daß das durch die hohle Drehachse des Zylinders in diesen eingeführte Rohr zur Abführung des Kondenswassers in einer radialen Entfernung von der Achse mündet, die größer ist als die radiale Entfernung der Rippenitinenflächen. Die Heizrippen 2 werden vorteilhafter-«eise so angeordnet, daß das sich an der tiefsten Stelle des Zylinders -ansanituelnde Kondenswasser einer bestimmten Stelle zufließen kann. von wo das Kondensat durch das erwähnte Abführungsrohr entfernt wird.In the drawing, the invention in several embodiments Illustrated for example, Fig. i shows a drying cylinder in longitudinal section. in which the cylindrical inner surface i with ribs running all around or otherwise designed elevations a is provided that the result of the Spin effect between them forming water ring 3 or part of the ribs Leaves 2 bumps free. so that this is with the one located inside the cylinder Are in direct contact with heating steam. For this it is necessary that that through the hollow axis of rotation of the cylinder inserted into this tube for the discharge of the condensed water opens at a radial distance from the axis which is greater than the radial Removal of the rib tine surfaces. The heating ribs 2 are more advantageous arranged in such a way that it is at the lowest point of the cylinder Condensation water can flow to a certain point. from where the condensate comes through the mentioned discharge pipe is removed.
Abb. 2 zeigt eine Ausführung. bei der die Heizrippen 2 schraubenartig verlautend ausgebildet sind, so- daß das Kondenswasser wie mittels -einer Förderschnecke gegen die _lbzugstelle befördert wird, an der das Abfiihrungsrolir iniindet.Fig. 2 shows an embodiment. in which the heating ribs 2 are helical are apparently designed so that the condensation water as by means of a screw conveyor to the point of departure where the discharge roller starts.
Abb.3 veranschaulicht eine ähnliche Anordnung, bei der aber die Heizrippen a in zwei Gruppen nach einer links- und einer rechtsgängigen Schraube verlaufen. so daß die Abzugstelle .f au beliebiger Stelle längs der Zylinderachse gewählt werden kann.Fig.3 illustrates a similar arrangement, but with the heating fins a run in two groups after a left-hand and a right-hand screw. so that the withdrawal point .f can be selected anywhere along the cylinder axis can.
Die Heizrippen können auch in anderer Weise, z. F. segmentartig bzw. unterbrochen, wie in Abb. 4. angedeutet, ausgebildet werden, um den günstigsten Abflußweg für das Kondensat zu ermöglichen.The heating fins can also be used in other ways, e.g. F. segment-like or interrupted, as indicated in Fig. 4., trained to be the most favorable To enable drainage path for the condensate.
