Verfahren und Vorrichtung zur Abdichtung benachbarterMethod and device for sealing adjacent
RäumeSpaces
Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zur gegenseitigen Abdichtung zweier benachbarter Räume, die über einen zum Durchtritt einer Materialbahn bestimmten Schlitz miteinander in Verbindung stehen.The invention relates to a method and a device for the mutual sealing of two adjacent ones Spaces that are connected to one another via a slot intended for a web of material to pass through.
Bei der kontinuierlichen Behandlung von Materialbahnen aus Textilien, Kunststoffen, Papier und dergleichen muß die Materialbahn häufig nacheinander verschiedene Räume durchlaufen, in denen sie unterschiedlichen Behandlungen ausgesetzt ist. So kann beispielsweise auf eine wärmebehandlung in dem einen Raum eine Kühlung im benachbarten Raum folgen.In the continuous treatment of material webs made of textiles, plastics, paper and the like must the web of material often pass through different rooms one after the other, in which it is subjected to different treatments is exposed. For example, heat treatment in one room can be followed by cooling in the neighboring one Follow space.
Tn vielen solchen Fällen kommt es darauf an, die benachbarten Räume, die durch den zum Durchtritt der Materialbahn bestimmten Schlitz miteinander in Verbindung stehen, möglichst gasdicht gegeneinander abzuschließen, um den unerwünschten Übertritt des gasförmigen Mediums aus dem einen Raum in den benachbarten Raum zu verhindern, so ist es beispielsweise bei der benachbarten Anordnung eines Trocknungsraumes und eines KUhlraumes unerwünscht, wennIn many such cases it depends on the neighboring Spaces that are in communication with one another through the slot intended for the passage of the material web, to seal against each other as gas-tight as possible in order to prevent the undesired passage of the gaseous medium from the To prevent a space in the adjacent room, so it is, for example, with the adjacent arrangement of one Drying room and a cold room undesirable if

heiße Trocknungsluft in den Kühlraum überströmt und umgekehrt. Beim Arbeiten mit im Umlauf geführten, durch Kondensation zurückgewonnenen Lösungsmitteln bringt ein Austreten von Lösungsmitteldämpfen in benachbarte Räume gleichfalls erhebliche Schwierigkeiten mit sich, da diese entwichenen Lösungsmitteldämpfe nur schwer niedergeschlagen und zurückgewonnen werden können.hot drying air flows over into the cooling space and vice versa. When working with circulating, through condensation Recovered solvents also lead to the escape of solvent vapors into neighboring rooms considerable difficulties with it, since these escaped solvent vapors are only difficult to condense and recover can be.
Es ist bekannt, solche durch einen Materialbahndurchtrittsschlitz miteinander verbundenen, benachbarten Räume mit Hilfe von mechanischen Elementen, beispielsweise Rollen oder Dichtlippen, gegeneinander abzudichten. Diese mechanischen Elemente stehen in Berührung mit der Materialbahn und führen daher bei empfindlichen Materialien leicht zu einer Beeinträchtigung der Oberflächenqualität.It is known to pass such a slot through a material web passage interconnected, adjacent rooms with the help of mechanical elements, such as rollers or sealing lips to seal against each other. These mechanical elements are in contact with the material web and therefore easily lead to a deterioration in the surface quality of sensitive materials.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zu entwickeln, das eine berührungsfreie, weitgehende Abdichtung benachbarter Räume gestattet.The invention is therefore based on the object of developing a method which is largely contact-free Sealing of neighboring rooms permitted.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß aus wenigstens einem der beiden Räume darin enthaltenes gasförmiges Medium abgesaugt und im Bereich des Schlitzes unter einem kleinen Winkel gegenüber der Materialbahn wieder in diesen Raum eingeblasen wird.According to the invention, this object is achieved in that at least one of the two spaces contained therein sucked gaseous medium and in the area of the slot at a small angle to the material web is blown back into this room.
Diese annähernd tangential zur Materialbahn verlaufende, zusätzliche Gasströmung wirkt dem Austritt von in dem betreffenden Raum enthaltenem gasförmigen Medium durch den Materialbahndurchtrittsschlitz wesentlich entgegen. Da dieses Verfahren berührungsfrei arbeitet, ist auch bei empfindlichen Materialien eine Beeinträchtigung der Oberflächenqualität nicht zu befürchten.This additional gas flow, which runs approximately tangentially to the material web, acts on the outlet from in the relevant space contained gaseous medium through the material web passage slot substantially against. Since this If the process works without contact, the surface quality is impaired, even with sensitive materials not to fear.

Es versteht sich, daß die zum erneuten Einblasen des abgesaugten gasförmigen Mediums in den Raum dienenden, im Bereich des Materialbahndurchtrittsschlitzes angeordneten Düsen so gestaltet und angeordnet sein müssen, daß das aus den Düsen ausströmende Medium keine nennenswerte Sogwirkung auf das im benachbarten Raum befindliche gasförmige Medium ausübt.It goes without saying that the nozzles arranged in the area of the material web passage slot must be designed and arranged so that the The medium flowing out of the nozzles has no significant suction effect on the gaseous in the adjacent room Medium exercises.
Ein AusfUhrungsbeispiel der Erfindung ist in der Zeichnung schematir-ch veranschaulicht.An exemplary embodiment of the invention is shown in the drawing schematir-ch illustrated.
Die in Richtung des Pfeiles 1 bewegte Materialbahn 2 durchsetzt nacheinander die beiden benachbarten, abgeschlossenen Räume 3 und 4 und tritt dann in den Außenraum 5. In der Zwischenwand 6 zwischen den Räumen 3 und 4 sowie in der Außenwand 7 ist je ein Schlitz 8 bzw. 9 zum Durchtritt der Materialbahn 2 vorgesehen.The material web 2 moved in the direction of arrow 1 passes through the two adjacent, closed ones one after the other Rooms 3 and 4 and then enters the outside room 5. In the partition wall 6 between rooms 3 and 4 as well as in the outer wall 7 is each a slot 8 or 9 for passage the material web 2 is provided.
Um die Räume 3 und 4 gegeneinander sowie den Raum 4 vom Außenraum 5 abzudichten, sind paarweise angeordnete Schlitzdüsen 1C,11 und 12 vorgesehen. Die Schlitzdüsen 11 und 12 sind über die dargestellten Leitungen an einen gemeinsamen Ventilator 13 angeschlossen, der gasförmiges Medium aus dem Raum 4 absaugt. Das abgesaugte Gas wird aus den Schlitzdüse!: 11 und 12 unter einem kleinen Winkel geger.über der Materialbahn 2, annähernd-tangential, wieder in den Raum 4 eingeblasen (Pfeile 14,15). Auf diese Weise wird einem Austritt des im Kaum 4 enthaltenen gasförmigen Mediums in den Raum 3 oder in den Außenraum 5 entgegengewirkt,In order to seal off the spaces 3 and 4 from one another and the space 4 from the outside space 5, they are arranged in pairs Slot nozzles 1C, 11 and 12 are provided. The slot nozzles 11 and 12 are connected to a common one via the lines shown Fan 13 connected, which sucks the gaseous medium from the space 4. The extracted gas will be out the slot nozzle !: 11 and 12 at a small angle opposite the material web 2, approximately tangentially, blown back into the space 4 (arrows 14, 15). That way will counteracts an escape of the gaseous medium contained in the barely 4 into the space 3 or into the outer space 5,
Die Schlitzdüsen 10 des Raumes 3 werden von dem nicht dargestellten Ventilator versorgt, der diesem Raum 3 zugeordnet ist.The slot nozzles 10 of the room 3 are supplied by the fan, not shown, which is assigned to this room 3 is.
