Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum fortlaufenden Mischen mindestens einer Zusatzflüssigkeit mit einem kontinuierlichen Strom einer viskosen Masse durch Umrühren.The invention relates to a method and an apparatus for continuously mixing at least one additional liquid with a continuous stream a viscous mass by stirring.

Bisher hat man die flüssigen Zusätze, z. B. Färbpigmentdispersionen, fortlaufend den in einem Mischrohr strömenden Massen, z. B. Spinnmassen, beigegeben und das Ganze mittels eines Stiftrührers, dessen Welle achsengleich mit dem Mischrohr verläuft, durchgeführt. Hierbei zeigte es sich, daß der Zusatz durch die rotierenden Stifte in der viskosen Masse zunächst in Ringform verteilt wurde. Der Ring nahm nach und nach die Form eines Schlauches an, der sich mit der viskosen Masse gleichzeitig in axialer Richtung im Rohr weiterbewegte. Diese schlauchartige Verteilung erstreckte sich über das ganze Mischrohr und behielt überall ihre Form fast unzerstört bei, da die Strömung bei viskosen Massen typisch laminar, d. h. wirbelfrei ist.So far you have the liquid additives such. B. Color pigment dispersions, continuously the masses flowing in a mixing tube, e.g. B. spinning masses added and the whole thing by means of a pin stirrer whose shaft runs on the same axis as the mixing tube, carried out. It was found that the addition by the rotating pins in the viscous Mass was initially distributed in a ring shape. The ring gradually took the shape of a tube, which moved along with the viscous mass in the axial direction in the pipe at the same time. This hose-like Distribution extended over the entire mixing tube and retained its shape almost undamaged everywhere at, since the flow of viscous masses is typically laminar, i.e. H. is eddy-free.

Es wurde nun gefunden, daß eine homogene Ver- ao mischung der Zusatzflüssigkeit über den gesamten Querschnitt des Stromes erreicht wird, wenn erfindungsgemäß das Umrühren in quer zur Strömungsrichtung der Masse verlaufenden und außerdem abwechselnd in einem Winkel gegeneinander versetzten Rotationsebenen vorgenommen wird.It has now been found that a homogeneous mixture of the additional liquid over the entire Cross-section of the flow is achieved when, according to the invention, the stirring is carried out transversely to the direction of flow of the mass and also alternately is made at an angle to each other offset planes of rotation.

Der Massestrom mit den einverleibten Zusätzen wird auf diese Weise auf seinem Weg durch das Mischrohr kreuz und quer verwirbelt.The mass flow with the incorporated additives is in this way on its way through the Mixing tube swirled all over the place.

Die Vorrichtung zur Ausübung des Verfahrens besteht aus mehreren im Abstand voneinander angeordneten Rührorganen, deren Achsen erfindungsgemäß quer, vorzugsweise senkrecht zur Achse des Mischrohres und außerdem in einem Winkel von vorzugsweise 90° zueinander versetzt angeordnet sind.The device for performing the method consists of several spaced apart Agitators whose axes according to the invention are transverse, preferably perpendicular to the axis of the mixing tube and are also arranged offset from one another at an angle of preferably 90 °.

In der Zeichnung sind Ausführungsbeispiele des Erfindungsgegenstandes schematisch dargestellt.Exemplary embodiments of the subject matter of the invention are shown schematically in the drawing.

Das zylindrische Mischrohr 1 wird vom viskosen Massestrom, z. B. einer Spinnlösung, die durch den Stutzen 2 in das Rohr 1 eintritt und durch den Stutzen 3 austritt, kontinuierlich in Richtung der Pfeile durchflossen. Durch die in den Stutzen 2 mündende Leitung 4 wird die Zusatzflüssigkeit, z. B. ein Farbpigment, in den Strom eingeführt; innerhalb des Mischrohres 1 befinden sich Rührer 5, 6, 7 und 8, deren Achsen 9, 10, 11 und 12 senkrecht zur Achse des Mischrohres 1 und zusätzlich wechselweise im rechten Winkel zueinander versetzt angeordnet sind. Der Antrieb der Rührer erfolgt über die Räder 13, 14, 15 und 16. Durch den Einbau von vier Rührorganen innerhalb des Mischrohres findet für den Verfahren und VorrichtungThe cylindrical mixing tube 1 is from the viscous mass flow, z. B. a spinning solution, which by the Nozzle 2 enters the pipe 1 and exits through the nozzle 3, continuously in the direction of the Arrows flowed through. Through the line 4 opening into the nozzle 2, the additional liquid, for. B. a Color pigment introduced into the stream; inside the mixing tube 1 there are stirrers 5, 6, 7 and 8, whose axes 9, 10, 11 and 12 are perpendicular to the axis of the mixing tube 1 and also alternately in the are arranged offset from one another at right angles. The stirrer is driven by the wheels 13, 14, 15 and 16. The installation of four agitators inside the mixing tube means that the Method and device

durchlaufenden Strom ein mehrmaliger Wechsel der Wirbelebenen statt. Ein mindestens einmaliger Wechsel ist für die Durchführung des Verfahrens erforderlich. a repeated change of the eddy planes takes place. A change at least once is necessary for the implementation of the procedure.

Die Mischung geht in ihren einzelnen Phasen folgendermaßen vor sich: Die durch die Leitung 4 eintretende Zusatzflüssigkeit läuft zunächst in den viskosen Hauptstrom in Form eines Stranges mit, wird dann durch den Rührer 5 in der Masse derart verteilt, daß sie die Form eines Bandes annimmt, dessen Ebene senkrecht zur Achse des Rührers 5 verläuft. Der Zusatz wird zu diesem Band ausgezogen, bis zum Rührer 6 innerhalb der viskosen Masse mitgenommen und durch diesen Rührer, dessen Achse um 90° versetzt zu der des Rührers 5 angeordnet ist, praktisch über den ganzen Querschnitt des durch das Mischrohr 1 fließenden viskosen Stromes verteilt.The mixing takes place in its individual phases as follows: The one entering through line 4 Additional liquid initially runs along with the viscous main flow in the form of a strand then distributed by the stirrer 5 in the mass in such a way that it takes the form of a band, its Plane runs perpendicular to the axis of the stirrer 5. The addition to this tape will be pulled off until Stirrer 6 taken along within the viscous mass and offset by this stirrer whose axis is 90 ° to which the stirrer 5 is arranged, practically over the entire cross section of the through the mixing tube 1 flowing viscous stream distributed.

Um den Mischeffekt zu verstärken und die Homogenisierung der Mischung je nach Zähigkeit des Hauptstromes noch vollständiger durchzuführen, sind in dem Mischrohr 1 anschließend an die Rührorgane 5 und 6 die Rührwerke 7 und 8 angeschlossen, deren Achsen ebenfalls um 90° versetzt angeordnet sind.To increase the mixing effect and to homogenize the mixture depending on the toughness of the Main stream to be carried out even more completely, are in the mixing tube 1 subsequent to the agitator 5 and 6, the agitators 7 and 8 are connected, the axes of which are also arranged offset by 90 °.

Als scheibenförmige Rührer können in einer Ebene angeordnete Stabrechen, gelochte Scheiben oder mit Sieben bespannte Ringe Anwendung finden.
