Description

Die Erfindung betrifft eine Wärmebehandlungsvorrichtung, insbes. einen Trockner für instabile Warenbahnen, wie Textilbahnen oder dergl., bei der gas- oder dampfförmiges Behandlungsmittel aus in oberhalb und/oder unterhalb einer Warenbahn angeordneten Flächen befindlichen Zu- und Abströmöffnungen, die mit Zu-und Abströmräumen verbunden sind, auf die Warenbahn aufgeblasen und von dieser wieder abgeführt wird, wobei die der Warenbahn zugewandten Flächen mit den Zu- und Abströmöffnungen die Böden von Düsenkörpern für die Zuführung des Behandlungsmittels sind, in denen eine Vielzahl von über die ganze Bodenfläche verteilte Zu- und Abströmöffnungen in der Weise angebracht sind, daß sowohl in Laufrichtung der Warenbahn als auch über die Breite der Warenbahn gleiche, relativ kleinflächige neben- und hintereinanderliegende, in sich strömungsmäßig abgeschlossene Behandlungseinheiten ohne nennenswerte resultierende Strömungskomponenten längs- oder quer zur Warenbahn über mehrere Behandlungseinheiten hinweg gebildet werden.The invention relates to a heat treatment device, in particular a dryer for unstable webs, such as textile webs or the like, in which gaseous or vaporous treatment agent consists of inflow and outflow openings located in areas arranged above and / or below a web, which have inflow and outflow spaces are connected, inflated and removed from the web, the surfaces facing the web with the inflow and outflow openings being the bottoms of nozzle bodies for the supply of the treatment agent, in which a large number of inflows and outlets distributed over the entire floor surface Outflow openings are attached in such a way that both in the direction of travel of the web and across the width of the web, the same, relatively small-area side by side and one behind the other, self-contained treatment units without significant flow components along or across the web over several treatment units ten are formed.

Es ist bei der Behandlung von Warenbahnen mit gas- oder dampfförmigen Behandlungsmitteln bekannt, bei, um das freie Schrumpfen der Warenbahn bei der Behandlung nicht zu behindern, d. h. um eine spannungsarme Ware zu erhalten, lose in Spannketten durch die Behandlung geführten Warenbahnen oder bei, um Abfleckungen der feuchten Warenbahn an Führungselementen wie Walzen oder dergl. durch die Warenbahn zu verhindern, frei schwebend durch den Behandlungsraum geführten Warenbahnen das Behandlungsmittel in der Weise auf die Warenbahnen zu blasen, daß die Warenbahnen vom Behandlungsmittel frei zwischen den Flächen mit den Zu- und Abströmöffnungen getragen werden.It is known in the treatment of webs with gaseous or vaporous treatment agents, in order not to hinder the free shrinkage of the web during the treatment, i. H. in order to obtain a low-tension product, loosely in tension chains through the treatment-guided product webs, or in order to prevent the wet product web from being stained by guide elements such as rollers or the like, by the product web floating freely through the treatment room, the treatment agent in such a way on the To blow material webs that the material webs are carried freely by the treatment agent between the surfaces with the inflow and outflow openings.

Die Erfahrung hat nun gezeigt, daß dieses erstrebenswerte Ziel bei den bekannten Vorrichtungen und Anordnungen zur Zu- und Abführung des gas- oder dampfförmigen Behandlungsmittels zu und von der Warenbahn insbesondere bei sehr instabilen Warenbahnen nur unvollkommen erreicht wird. Es treten vielmehr immer mehr oder weniger starke Flattererscheinungen mit Anschlagen der Warenbahnen an die Düsenkörper auf und außerdem mehr oder weniger stark ausgeprägte gerichtete Strömungen über weite Bereiche der Warenbahnen, die zu Faltenbildungen in den Warenbahnen führen.Experience has now shown that this desirable goal is only incompletely achieved in the known devices and arrangements for supplying and discharging the gaseous or vaporous treatment agent to and from the web, in particular in the case of very unstable webs. Rather, more or less pronounced fluttering phenomena occur with the material webs striking the nozzle body and, moreover, more or less pronounced directional flows over large areas of the material webs, which lead to wrinkling in the material webs.

Dieses wird auch nicht durch eine Lochdüsenanordnung nach der DE-A-3 232 613 verhindert, bei der zwischen den bekannten üblichen Düsenkörpern und der Warenbahn eine Trennwand angeordnet ist, in der Öffnungen für die Zu-und Abführung des Behandlungsmittels zur und von der Warenbahn angebracht sind, weil das abströmende Behandlungsmittel auf der der Warenbahn abgewandten Seite der Trennwand unmittelbar im Bereich der Düsen in allen Richtungen strömen kann, womit aber auch die Abströmung aus den, Düsen behindert wird in dem Sinn, daß die Abströmung nicht gleichmäßig sein kann mit den genannten Folgen. Außerdem sind bei dieser Anordnung keine klaren Zuordnungen der Abströmöffnungen zu den Zuströmöffnungen gegeben, was zur Folge hat, daß leistungsmindernde Querströmungen an der Warenbahn auftreten. Weiterhin ist die Ausbildung der Zuströmöffnungen mit größerem Durchmesser als dem der Abströmöffnungen für die Behandlungswirkung und die Strömungsführung ungüstig.This is also not prevented by a perforated nozzle arrangement according to DE-A-3 232 613, in which a partition is arranged between the known conventional nozzle bodies and the web, in which openings for the supply and discharge of the treatment agent to and from the web are provided are because the outflowing treatment agent on the side of the partition facing away from the web can flow directly in the area of the nozzles in all directions, but this also hinders the outflow from the nozzles in the sense that the outflow cannot be uniform with the aforementioned Consequences. In addition, in this arrangement there are no clear assignments of the outflow openings to the inflow openings, which has the consequence that cross-flows which reduce performance occur on the material web. Furthermore, the formation of the inflow openings with a larger diameter than that of the outflow openings is unfavorable for the treatment effect and the flow guidance.

Durch die vorliegende Erfindung sollen diese Nachteile der bekannten Vorrichtungen und Anordnungen vermieden und die Aufgabe gelöst werden, eine Wärmebehandlungsvorrichtung zu schaffen, bei der nicht nur ein einwandfreies Tragen der Warenbahnen durch das Behandlungsmittel ohne Anschlagen der Bahnen an die Düsenkörper auch bei kleinen für eine gute Behandlungswirkung erwünschten Abständen zwischen den Bahnen und den Düsenkörpern vermieden wird, sondern bei der auch keine resultierenden Strömungskomponenten in der Warenbahnebene auftreten können.The present invention is intended to avoid these disadvantages of the known devices and arrangements, and to solve the problem of creating a heat treatment device in which not only is the fabric correctly carried by the treatment agent without the webs striking the nozzle body, even with small ones, for a good treatment effect desired distances between the webs and the nozzle bodies is avoided, but at which no resulting flow components can occur in the web plane.

Zur Lösung dieser Aufgabe wird erfindungsgemäß bei einer Wärmebehandlungsvorrichtung der eingangs genannten Art vorgeschlagen, bei den Behandlungseinheiten jeweils mehrere Zuströmungsöffnungen stern- bzw. ringförmig um eine zentrale Abströmöffnung, welche mittels eines durch den Düsenkörper hindurchgeführten Rohres mit dem Abströmraum verbunden ist, anzuordnen.To achieve this object, it is proposed according to the invention in a heat treatment device of the type mentioned at the outset to arrange a plurality of inflow openings in the treatment units in a star or ring shape around a central outflow opening which is connected to the outflow space by means of a pipe which is guided through the nozzle body.

Die Zu- und Abströmöffnungen können dabei als runde Bohrungen oder auch als Schlitze in den Bodenflächen der Düsenkörper ausgebildet sein. Besonders günstige Strömungsverhältnisse werden erreicht, wenn die Zu- bzw. Abströmöffnungen gleiche Abstände zu den zugeordneten Ab- bzw. Zuströmöffnungen aufweisen.The inflow and outflow openings can be designed as round bores or as slits in the bottom surfaces of the nozzle bodies. Particularly favorable flow conditions are achieved if the inflow and outflow openings are at equal distances from the assigned outflow and inflow openings.

Zur Erzielung einer gleichmäßigen Behandlung der Warenbahn sollen in Laufrichtung der Warenbahn hintereinanderliegende Behandlungseinheiten versetzt zueinander sein. Auch quer zur Laufrichtung können die Behandlungseinheiten zueinander versetzt sein. Es kann auch eine Kombination beider Möglichkeiten vorgesehen werden.In order to achieve a uniform treatment of the material web, treatment units lying one behind the other in the running direction of the material web should be offset from one another. The treatment units can also be offset from one another transversely to the running direction. A combination of both options can also be provided.

Die oberhalb und unterhalb der Warenbahn befindlichen Behandlungseinheiten können spiegelbildlich zueinander liegen, sie können aber auch versetzt zueinander sein.The treatment units located above and below the web can be mirror images of one another, but they can also be offset from one another.

In den Figuren sind gleiche Teile mit gleichen Bezugszeichen versehen.In the figures, the same parts are provided with the same reference symbols.

In den Figuren 1 bis 3, sind verschiedene Ausführungsformen von Behandlungseinheiten 15 dargestellt, bei denen um eine zentrale Abströmöffnung 13 jeweils mehrere Zuströmöffnungen 12 angeordnet sind. Es liegt auch im Rahmen der Erfindung, daß die Zuströmöffnungen und die Abströmöffnungen gegeneinander vertauscht sind. In Fig. 1 weisen die als Bohrungen ausgebildeten Zuströmöffnungen 12 einen gleichmäßigen Abstand zur Abströmöffnung 13 auf, während sie in Fig. 2 sternförmig, d. h. mit unterschiedlichen Abständen um die Abströmöffnung angeordnet sind. In Fig. 3 sind die Zuströmöffnungen 12 als Schlitze ausgebildet, die, anders als dargestellt, auch alle konzentrisch um die Abströmöffnung herum liegen können.FIGS. 1 to 3 show different embodiments of treatment units 15 in which a plurality of inflow openings 12 are arranged around a central outflow opening 13. It is also within the scope of the invention that the inflow openings and the outflow openings are interchanged. In Fig. 1, the inflow openings 12 designed as bores are at a uniform distance from the outflow opening 13, while in Fig. 2 they are star-shaped, ie. H. are arranged at different distances around the outflow opening. In Fig. 3, the inflow openings 12 are formed as slots which, unlike shown, can also all be concentric around the outflow opening.

In Fig. 4 sind Ausschnitte aus Böden von Düsenkörpern wiedergegeben, die erkennen lassen, wie sich die erfindungsgemäßen Behandlungseinheiten 15 auf dem Boden verteilen. In der Figur ist die Laufrichtung der Warenbahnen durch Pfeile gekennzeichnet. Man sieht, daß die Behandlungseinheiten 15 in Laufrichtung der Warenbahn gegeneinander versetzt sind. Die Behandlungseinheiten können jedoch auch quer zur Laufrichtung der Warenbahn versetzt sein. Auch eine dieser Kombination dieser Versätze ist möglich.4 shows sections from the bottoms of nozzle bodies which show how the treatment units 15 according to the invention are distributed over the bottom. In the figure, the direction of travel of the webs is indicated by arrows. It can be seen that the treatment units 15 are offset from one another in the running direction of the web. However, the treatment units can also be offset transversely to the direction of travel of the web. One of these combinations of these offsets is also possible.

Der in Fig. 5 dargestellte Düsenkörper 14 ist ein unterhalb der Warenbahn angeordneter Düsenkörper und läßt insgesamt die Anordnung der Zu-12 und Abströmöffnungen 13, sowie die Luftzuführung in den Düsenkörper und von dort zu den Zuführungsöffnungen 12 erkennen. Einzelheiten dazu sind aus Fig. 6 zu entnehmen, bei der oberhalb und unterhalb der Warenbahn 10 Düsenkörper 14 mit Zu- 12 und Abströmöffnungen 13 dargestellt sind. Die Führung der Behandlungsmittelströme ist durch Pfeile gekennzeichnet. Man erkennt, daß das Behandlungsmittel aus dem Innenraum der Düsenkörper durch die Zuströmöffnungen 12 auf die Warenbahn aufgeblasen und von dort durch die Abströmöffnungen 13, die mittels durch die Düsenkörper hindurchgeführter Rohre 16 mit dem Abströmraum 17 verbunden sind, abgeführt wird.The nozzle body 14 shown in FIG. 5 is a nozzle body arranged underneath the web and, overall, shows the arrangement of the inlet and outlet openings 13, as well as the air supply into the nozzle body and from there to the supply openings 12. Details can be found in FIG. 6, in which 10 nozzle bodies 14 with inflow and outflow openings 13 are shown above and below the web. The guidance of the treatment agent flows is indicated by arrows. It can be seen that the treatment agent is inflated from the interior of the nozzle body through the inflow openings 12 onto the fabric and from there through the outflow openings 13, which are connected to the outflow space 17 by means of pipes 16 guided through the nozzle body.
