Abstract

Eine Flüssigkeit, die durch ein Verteilerrohr strömt und auf mehrere, vom Verteilerrohr abzweigende Abgänge verteilt wird, läßt sich schneller durch eine andere Flüssigkeit verdrängen, beispielsweise beim Farbwechsel von Spinnlösungen, wenn man die vor einem beliebigen Abgang befindliche, gesamte wandnahe Flüssigkeitsschicht durch diesen Abgang zum Abströmen bringt.A liquid that flows through a distributor pipe and is distributed to several outlets branching off from the distributor pipe can be displaced more quickly by another liquid, for example when changing the color of spinning solutions, if one passes the entire liquid layer near the outlet through this outlet to the outlet Outflow brings.

Description

Die Erfindung betrifft ein Verfahren zum Verteilen von Flüssigkeiten, die durch ein Verteilerrohr strömen, auf mehrere vom Verteilerrohr abzweigende Abgänge, bei dem das Verdrängen einer Flüssigkeit durch eine andere schneller als bisher erfolgt.The invention relates to a method for distributing liquids which flow through a distributor pipe to a plurality of outlets branching off from the distributor pipe, in which one liquid is displaced by another more quickly than hitherto.

Die Erfindung betrifft weiterhin eine Vorrichtung zum Verteilen von Flüssigkeiten, bestehend aus einem Verteilerrohr und mehreren, vom Verteilerrohr abzweigenden, vorzugsweise gleichartigen Abgängen in Form von Rohren mit kleinerem Durchmesser als das Verteilerrohr, beispielsweise einem Verteilerrohr, mit dem eine Spinnlösung auf mehrere Spinnstellen verteilt wird.The invention further relates to a device for distributing liquids, consisting of a distributor tube and several, preferably identical branches branching off from the distributor tube in the form of tubes with a smaller diameter than the distributor tube, for example a distributor tube with which a spinning solution is distributed to several spinning stations.

Bei der Herstellung von Spinnfäden durch Verspinnen einer Spinnlösung oder Spinnschmelze wird die Lösung oder Schmelze durch ein Verteilerrohr über engere Rohre, die vom Verteilerrohr abzweigen (Abgänge) zu den Spinnstellen transportiert und dort durch die Spinndüsen zu Fäden versponnen. Zu Problemen kommt es, wenn ein Spinnlösungswechsel, beispielsweise durch einen Farbwechsel, vorgenommen wird. Da es sehr aufwendig ist, die Spinnmaschine abzuschalten, zu reinigen und mit der neuen Spinnlösung oder -schmelze wieder anzufahren, wird der Spinnbetrieb nicht unterbrochen, sondern die bisherige Spinnlösung oder -schmelze wird durch die neue Spinnlösung oder -schmelze verdrängt. Das führt zu oft stundenlangen Umspinnzeiten, in denen unbrauchbares Material erzeugt wird, weil eine Vermischung der neuen mit der alten Spinnlösung oder -schmelze stattfindet. Insbesondere störend ist, daß in Fließrichtung der Lösung oder der Schmelze gesehen, an den ersten vom Verteilerrohr abzweigenden Spinnstellen bereits einwandfreies Material erzeugt wird, während an den letzten Spinnstellen nach wie vor Ausschuß produziert wird. Da bekanntlich die Fäden einer bestimmten Anzahl von Spinnstellen zu einem Band oder Kabel zusammengefaßt werden und die Bandstärke möglichst nicht geändert wird, auch nicht während der Umspinnzeit, muß das einwandfreie Material aus den vorderen Spinnstellen solange ausgemustert werden, bis auch die letzte Spinnstelle einwandfreies Material produziert.In the production of spun threads by spinning a spinning solution or spinning melt, the solution or melt is transported through a distributor pipe via narrower pipes which branch off from the distributor pipe (outlets) to the spinning stations and there are spun into threads through the spinnerets. Problems arise when a spinning solution change, for example by changing the color. Since it is very complex to switch off the spinning machine, clean it and start it up again with the new spinning solution or melt, the spinning operation is not interrupted, but the previous spinning solution or melt is displaced by the new spinning solution or melt. This often leads to hours of re-spinning in which unusable material is produced because the new spinning solution or melt is mixed with the old one. It is particularly troublesome that, viewed in the direction of flow of the solution or the melt, perfect material is already produced at the first spinning stations branching off from the distributor pipe, while rejects are still produced at the last spinning stations. As is known, the threads of a certain number of spinning stations are combined into a band or cable and the band thickness is not changed as far as possible, not even during the spinning time, the flawless material from the front spinning stations must be retired until the last spinning station also produces flawless material .

Dieser unerwünschte Effekt wird dadurch erzeugt, daß wegen der Reibung der Flüssigkeit an den Wänden, die in der :r Mitte des Verteilerrohres transportierte Flüssigkeit schneller strömt, so daß die an den Wänden strömende erste Flüssigkeit den letzten Abgang erst erreicht, wenn an den ersten Abgängen bereits ausschließlich die zweite Flüssigkeit abfließt und der in der Mitte des Rohres strömende Anteil der zweiten Flüssigkeit den letzten Abgang längst erreicht hat.This undesirable effect is caused by the fact that, due to the friction of the liquid on the walls, the liquid transported in the middle of the distributor pipe flows faster, so that the first liquid flowing on the walls only reaches the last outlet when the first outlet only the second liquid is already flowing off and the portion of the second liquid flowing in the middle of the tube has long since reached the last outlet.

Aufgabe der vorliegenden Erfindung war es, ein Verfahren und eine Vorrichtung bereitzustellen, mit denen es gelingt, die Umspinnzeit zu reduzieren und vorzugsweise auf das unbedingte Minimum zu begrenzenr bzw. zu erreichen, daß an allen Abgängen das Auftreten der reinen zweiten Flüssigkeit gleichzeitig erfolgt.It was an object of the present invention to provide a method and a device with which it is possible to reduce the spinning time and preferably to limit it or to achieve that the appearance of the pure second liquid occurs simultaneously at all outlets.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die vor einem beliebigen Abgang befindliche, gesamte wandnahe Flüssigkeitsschicht durch diesen Abgang zum Abströmen gebracht wird.The object is achieved in that the entire liquid layer located in front of any outlet is caused to flow through this outlet.

Apparativ wird diese Aufgabe insbesondere dadurch gelöst, daß in Höhe jeden Abganges im Verteilerrohr richtungsgleich ein Rohreinsatz mit geringerem Durchmesser als das Verteilerrohr angebracht ist.In terms of apparatus, this object is achieved in particular in that a pipe insert with a smaller diameter than the distributor pipe is attached in the same direction at the level of each outlet in the distributor pipe.

Vorzugsweise beträgt der Innendurchmesser des Rohreinsatzes 60 bis 80 X des Innendurchmesser des Verteilerrohres. Der Außendurchmesser des Rohreinsatzes ist vorzugsweise 5 bis 40 X größer als der Innendurchmesser des Rohreinsatzes. Die Rohreinsatzlänge beträgt insbesondere 30 bis 80 % des Abstandes zwischen zwei Abgängen. Die Mitte der Rohreinsatzlänge kann sich in Höhe der Mitte des betreffenden Abganges befinden. Sie ist vorzugsweise um 0 bis 95 % der Rohreinsatzlänge entgegen der Fließrichtung der Flüssigkeit von der Mitte des Abganges verschoben.The inner diameter of the tube insert is preferably 60 to 80 X of the inner diameter of the distributor tube. The outside diameter of the pipe insert is preferably 5 to 40 times larger than the inside diameter of the pipe insert. The pipe insert length is in particular 30 to 80% of the distance between two outlets. The center of the pipe insert length can be at the center of the outlet in question. It is preferably shifted from 0 to 95% of the length of the pipe insert against the direction of flow of the liquid from the center of the outlet.

Die von der Flüssigkeit berührten Flächen des Verteilerrohres und der Rohreinsätze sind zweckmäßigerweise von gleichartig glatter Beschaffenheit, um Druckverluste wegen Reibung zu minimieren. Die Rohreinsätze werden mit Abstandshaltern im Verteilerrohr befestigt, wobei die Abstandshalter zweckmäßigerweise in einer gegenüber der Flüssigkeit strömungsgünstigen Weise gestaltet sind. Weiterhin ist es zweckmäßig, wenn auch nicht unbedingt erforderlich, die Rohreinsätze im Verteilerrohr konzentrisch anzubringen.The surfaces of the distributor pipe and the pipe inserts in contact with the liquid are expediently of a similarly smooth nature in order to minimize pressure losses due to friction. The pipe inserts are fastened with spacers in the distributor pipe, the spacers being expediently designed in a manner that is streamlined compared to the liquid. Furthermore, it is expedient, if not absolutely necessary, to attach the tube inserts concentrically in the distributor tube.

Die Figuren zeigen Längs- und Querschnittskizzen der erfindungsgemäßen Vorrichtung.The figures show longitudinal and cross-sectional sketches of the device according to the invention.

Fig. 1 zeigt im Längsschnitt das Verteilerrohr 1, in das in Pfeilrichtung die zu verteilende Flüssigkeit einfließt. 2 kennzeichnet die Rohreinsätze, 3 die Abgänge, an deren Ende Pumpen 4 angebracht sind, die die Flüssigkeit weiter transportieren, beispielsweise zu den Spinnstellen.Fig. 1 shows a longitudinal section of the distributor pipe 1, in which the liquid to be distributed flows in the direction of the arrow. 2 identifies the tube inserts, 3 the outlets, at the end of which pumps 4 are attached, which transport the liquid further, for example to the spinning stations.

Fig. 2 zeigt einen Querschnitt durch das Verteilerrohr in Höhe eines Abganges.Fig. 2 shows a cross section through the manifold at the level of an outlet.

Die erfindungsgemäße Vorrichtung ist nicht auf eine bestimmte Anzahl von Abgängen beschränkt, jedoch ergibt sich die optimale Zahl von Abgängen aus dem zu überwindenden Druckverlust und den damit verbundenen Aufwendungen. Durch die Rohreinsätze innerhalb des Verteilerrohres wird zwar der Druckverlust erhöht, jedoch nur in so untergeordnetem Umfang, daß eine Verkürzung des Verteilerrohres auf eine geringere Anzahl von Abgängen normalerweise nicht erforderlich ist.The device according to the invention is not limited to a specific number of outlets, but the optimal number of outlets results from the pressure loss to be overcome and the associated expenses. Through the pipe inserts within the manifold, the pressure loss is increased, but only to such a minor extent that the manifold is shortened to one less number of exits is normally not required.

Die erfindungsgemäße Vorrichtung eignet sich insbesondere zum Verteilen von Spinnlösungen oder -schmelzen auf mehrere Spinnstellen.The device according to the invention is particularly suitable for distributing spinning solutions or melts over several spinning stations.

Hierbei konnte eine Verringerung der Umspinnzeiten auf höchstens 20% der Dauer, die mit einem herkömmlichen Verteilerrohr ohne Einbauten erzielt wurde, erreicht werden.In this way, the spinning times could be reduced to a maximum of 20% of the duration achieved with a conventional distributor pipe without internals.

Die Fördermenge an Spinnlösung betrug 27 l/h. Die Spinnlösung enthielt einen roten Farbstoff und wurde zum Zeitpunkt 0 durch eine Spinnlösung, die einen blauen Farbstoff enthielt, ersetzt.In the distribution pipe concentric 200 mm long insert pipes with an inner diameter of 46 mm and a wall thickness of 2 mm were attached, the middle of which was 90% at the beginning, then gradually up to the last outlet by 5% of the length of the pipe inserts against the direction of flow of the liquid the middle of the respective outlet was shifted. The flow rate of spinning solution was 27 l / h. The spinning solution contained a red dye and was replaced at 0 with a spinning solution containing a blue dye.

Die Spinnlösungen wurden aus 1155-Lochdüsen mit 0,2 mm Düsenlochdurchmesser bei einer Abzugsgeschwindigkeit von 330 m/min trocken versponnen. Die Verweilzeit der Spinnfäden in den Spinnschächten betrug 15 Sekunden. Die Schachttemperatur lag bei 180°C und die Lufttemperatur betrug 280°C. Die durchgesetzte Luftmenge betrug 50 m3/h für jeden Schacht, die am Kopf des Schachtes in Längsrichtung zu den Fäden eingeblasen wurde.The spinning solutions were dry spun from 1155-hole nozzles with a nozzle hole diameter of 0.2 mm at a take-off speed of 330 m / min. The dwell time of the spun threads in the spinning shafts was 15 seconds. The shaft la temperature g at 180 ° C and the air temperature was 280 ° C. The throughput of air was 50 m 3 / h for each shaft, which was blown in at the head of the shaft in the longitudinal direction to the threads.
