Description

Vorrichtung zur kontinuierlichen Herstellung nahtloser, biegsamer Schläuche aus Celluloselösung Die Erfindung betrifft eine Vorrichtung zur kontinuierlichen Herstellung nahtloser. biegsamer Schläuche aus Celluloselösung, bei der die Lösung aus einer Ringdüse in ein Fällbad gelangt und gleichzeitig Fällflüssigkeit in (las aus der Düse austretende schlauchförmige Gebilde geleitet wird Bei einer derartigen Vorrichtung wird erfindungsgemäß zur Entfernung des verbrauchten Fällmittels im Innern des Schlauches ein Heber angeordnet.Apparatus for the continuous production of seamless, flexible Tubing made from cellulose solution The invention relates to a device for continuous Making more seamless. flexible tubing made of cellulose solution, in which the solution passes from an annular nozzle into a precipitation bath and at the same time the precipitation liquid is poured into (read The tubular structure emerging from the nozzle is guided in such a case According to the invention, the device is used to remove the spent precipitant A lifter is arranged inside the hose.

Durch die auf diese Weise erreichte (lauernde und gleichmäßige Abfuhr unwirksam gewordener Fällflüssigkeit aus dem entstelienden Schlauch wird eine gleichmäßige Form und Beschaffenheit des Schlauches gewälirleistet. Auch kann der Stand der Fällflüssigkeit im Schlauchinnern und im äußeren Fällbad leicht geregelt werden, da durch Einstellung eines im Heber vorgesehenen Hahnes bequem die Heberwirkung verändert werden kann. Ferner gestaltet sich die Flüssigkeitsentnahme (furch den Heber einfach und zuverlässig, da das verbrauchte Fällmittel im Schlauchinnern nach oben geht.Through the lurking and even discharge achieved in this way Ineffective precipitation liquid from the resulting hose becomes a uniform one Shape and texture of the hose are guaranteed. The level of the precipitating liquid can also be can be easily regulated inside the hose and in the outer precipitation bath, as by setting a cock provided in the lifter, the lifting effect can be changed easily. Furthermore, the liquid withdrawal is designed (for the siphon simple and reliable, because the used precipitant goes up inside the hose.

Zweckmäßig wird die Regelung der Zu-und Abfuhr des inneren Fällmittels so vorgenommen, daß der Flüssigkeitsspiegel innerhalb des entstehenden Schlauches gleich oder etwas höher ais der Stand des äußeren Fällbades ist. Man kann dies dadurch erreichen, daß der zur Abführung des verbrauchten inneren Fällmittels dienende Heber mit dem anderen Ende in das äußere Fällbad taucht, aus dem das verbrauchte Fällmittel über einen Überlauf abfließen kann. Dadurch wird auch ein ständiger gleichmäßiger Druckausgleich zwischen der inneren und der äußeren Fällflüssigkeit aufrechterhalten, was ebenfalls. für die Gleichmäßigkeit der herzustellenden Schläuche von Bedeutung ist. Die Zu- und Abführung der inneren Fällflüssigkeit erfolgt corteilhafterweise im Gegenstrom, indem das Zuführungsrohr möglichst tief unter dem Flüssigkeitsspiegel mündet und an diesem der Heber die infolge ihres geringeren spezifischen Gewichtes aufsteigende verbrauchte Fällflüssigkeit abnimmt.It is useful to regulate the supply and discharge of the internal precipitant made so that the liquid level is within the resulting tube equal to or slightly higher than the level of the outer felling bath. You can do this through this achieve that the lifter serving to remove the used inner precipitant the other end is immersed in the outer precipitation bath, from which the used precipitant is removed can flow off via an overflow. This also makes a constant more even Maintain pressure equalization between the inner and outer precipitating liquid, what also. important for the evenness of the hoses to be produced is. The internal precipitating liquid is supplied and removed in a corteilige manner in countercurrent by placing the feed pipe as deep as possible below the liquid level opens and at this the lifter due to its lower specific weight rising used precipitation liquid decreases.

Die Zeichnung zeigt die Vorrichtung nach der Erfindung in einem Ausführungsbeispiel. Aus der Ringdüse r fließt die Celluloselösung, z. B. Viskose, unmittelbar in das Fällbad 2 in Form einer zylindrischen Schicht 3 ein. In das Innere der Düse r, die in das Fällbad etwas eintauchen kann, ragt ein Rohr ,I hinein, das zur Zuführung von Fällflüssigkeit in rien Innenraum des entstehenden Schlauches 3 dient und mit einem Regelventil s versehen ist. Mit Hilfe des Hebers 6, der nur wenig unter die Oberfläche der inneren Fällflüssigkeit taucht und in seinem oberen Teil einen Regelhahn enthält, wird der verbrauchte Teil dieser Fällflüssigkeit dauernd und gleichmäßig abgeführt. Der Heber 6 mündet mit dem anderen Ende in das Fällbad 2, aus dem durch den Überlauf 7 das verbrauchte Fällmittel abfließt. Der sich bildende Schlauch 3 wird mit Hilfe der Rollen 8 und 9 aus dem Bad 2 zur Weiterbehandlung in den üblichen Wasch-, Bleich-, Entschwefelungs-, Färb- und Geschmeidigkeitsbädern herausgeführt.The drawing shows the device according to the invention in one embodiment. The cellulose solution flows out of the ring nozzle r, e.g. B. viscose, directly into the Precipitation bath 2 in the form of a cylindrical layer 3. In the interior of the nozzle r that can immerse something in the precipitation bath, protrudes a pipe, I, to the supply of precipitating liquid in rien interior of the resulting tube 3 is used and with a control valve s is provided. With the help of the lifter 6, which is only slightly under the Surface of the inner precipitation liquid is immersed and in its upper part a control valve contains the consumed part this precipitation liquid continuously and discharged evenly. The other end of the lifter 6 opens into the felling bath 2, from which the used precipitant flows through the overflow 7. The forming Hose 3 is removed from bath 2 with the help of rollers 8 and 9 for further treatment in the usual washing, bleaching, desulphurizing, dyeing and softening baths led out.

Durch das Regelventil s kann der Zufluß von innerer Fällflüssigkeit so eingestellt werden, daß die Erneuerung ständig entsprechend dem Verbrauch erfolgt, der von der Beschaffenheit der Celluloselösung, der Arbeitsgeschwindigkeit und den Abmessungen des herzustellenden Schlauches abhängt. Infolge der Wirkung des Hebers 6 besteht zwischen der inneren und der äußeren Fällflügsigkeit stets Druckausgleich. Um dem Schrumpfungsbestreben des entstehenden Schlauches entgegenzuwirken, kann im Schlauchinnern ein Überdruck erzeugt werden, indem z. B. die innere Fällflüssigkeit durch Verstellung des Regelhahnes des Hebers auf ein höheres Niveau als das äußere Fällbad eingestellt wird.The inflow of internal precipitating liquid can be controlled through the control valve s be set in such a way that the renewal takes place continuously according to consumption, that of the nature of the cellulose solution, the operating speed and the Dimensions of the hose to be produced depends. As a result of the action of the lifter 6 there is always pressure equalization between the inner and outer felling flux. In order to counteract the shrinkage tendency of the resulting tube, can an overpressure can be generated in the interior of the hose by z. B. the inner precipitation liquid by adjusting the control valve of the lifter to a higher level than the outside Precipitation bath is set.
