Description

  

  
 



  Einrichtung zum kontinuierlichen Herstellen von Lösungen und Suspensionen
Die vorliegende Erfindung bezieht sich auf leine   liin-    richtung zum kontinuierlichen Herstellen von Lösungen und Suspensionen.



   Kontinuierliche Löseprozesse sind mittels Schnekkenmaschinen verschiedener Bauart durchführbar. Dabei wurde jedoch als nachteilig empfunden, dass beim Dosieren im Einfüllbereich oft grössere Agglomerate entstehen, die vom Lösemittel umhüllt werden und den weiteren Lösevorgang erschweren. Nur durch Aufbringen von relativ grossen Scherkräften sind die gallertartigen Häute abzureiben, um dadurch neue Oberflächen für die Lösemittelpenetration frei zu legen. Dazu ist jedoch grosser technischer Aufwand nötig und oft müssen spezielle Reibelemente Anwendung finden. Bei der Herstellung von Suspensionen stellen sich oft ähnliche Probleme.



   Es wird angestrebt, eine Einrichtung vorzuschlagen, bei welcher bei separater Dosierung der Flüssigkeitskomponenten die Bildung von Agglomeraten verhindert wird, so dass diese mit bekannten Schneckenmaschinen verarbeitet werden können.



   Die erfindungsgemässe Einrichtung zum   kontinuierTi-    chen Herstellen von Lösungen und Suspensionen weist eine Knetvorrichtung und eine der Knetvorrichtung vorgeschaltete rotierende Mischvorrichtung auf, welche mit einer höheren Drehzahl als die Knetvorrichtung arbeitet.



  Zweckmässigerweise kann die Mischvorrichtung eine rotierende mit Misch- und Zerkleinerungsorganen versehene vertikale Welle   aufweisen.    Auf beiliegender Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch dargestellt.



   Die dargestellte Einrichtung zum kontinuierlichen Durchführen von Löseprozessen weist eine Knetvorrichtung 1 auf, welche eine in einem Gehäuse 2 rotierende Schnecke 3 besitzt, die mittels eines in einem Gehäuse 4 angeordneten nicht dargestellten Motors über ein Getriebe angetrieben wird. An die Einfüllöffnung des Gehäuses 2 ist eine Mischvorrichtung 5 mit ihrer Austrittsdüse 6 angeschlossen. Die Mischvorrichtung weist eine in einem vertikalen Gehäuse 7 langeordnete Welle 8 auf, die mit   Mlisch-und      Zerkleinerungsorganen    9 ausgerüstet ist. Die Misch- und   Zerkleinerungsorgane    9 sind entlang der Welle radial verteilt. Zum Antrieb der Welle 8 dient ein Elektromotor 10, welcher am oberen aus dem Gehäuse 7 herausragenden Ende der Welle 8 befestigt ist.

   Die Welle 8 rotiert   mit    mehrfach erhöhten Drehzahlen gegenüber der Schnecke 3.



   Die Feststoffe, welche in einer Flüssigkeit gelöst werden sollen, befinden sich in einem Behälter 11 und gelangen mittels eines Förderbandes oder Dosierwaage 12 durch den Einfüllstutzen 13 in die Mischvorrichtung.



  Der Einfüllstutzen 13 der Mischvorrichtung ist am oberen Teil des Gehäuses 7 angeordnet Die pulverförmigen Feststoffe   werden    im Gehäuse 7 von den rotierenden flügelartigen   Misch- und    Zerkleinerungsorganen erfasst und in wirbelnde Bewegung versetzt. Die Flüssigkeit wird aus   einem    Behälter 14 mittels einer Leitung 15 über eine Dosierpumpe 17 in das Gehäuse 7 eingeführt. An Stelle der einzigen Leitung 15, können weitere aus der Leitung 15 abzweigende Leitung vorhanden sein, die an verschiedenen Umfangsstellen in das Gehäuse 7 münden. Das benetzte oder angeteigte Material wird zwangläufig oder durch die Schwerkraft nach unten gefördert, wobei die relativ lockeren   Agglomerate    zerschlagen werden.

   Zur Unterstützung dieser Wirkung können im Gehäuse 7 noch Statorelemente 16 vorhanden sein, welche mit den Misch- und Zerkleinerungsorganen 9 zusammenwirken. Durch die Düse 6 tritt ein Gemenge in die Knetvorrichtung 1 ein, welches in dieser ohne   Schwierigkeiten    weiter   verarbeitet    wird.



   Die   beschriebene    Einrichtung ist z. B. besonders geeignet zur Lösung von Polyacrylnitril in Dimethylfornamid, von Acetyl-Cellulose in Aceton, PVC in Cyclohexanon usw. und Herstellung von Suspensionen z. B. aus Therephthalsäure und Glykol, wobei die Verweilzeit des Produktes in der kontinuierlichen gegenüber der chargenweise arbeitenden Einrichtung wesentlich herabgesetzt werden kann. Dadurch wird die Qualität des Produktes verbessert und beispielsweise ;bei der Lö  sung von Polyacrylnitril in Dimethylfornamid d die sonst     auftretende Gelbfärbung wesentlich herabgesetzt oder sogar ganz verhindert.   



  
 



  Device for the continuous production of solutions and suspensions
The present invention relates to a line for the continuous production of solutions and suspensions.



   Continuous dissolving processes can be carried out using various types of screw machines. However, it was found to be disadvantageous that when metering in the filling area, larger agglomerates are often formed which are enveloped by the solvent and make the further dissolving process more difficult. The gelatinous skins can only be rubbed off by applying relatively high shear forces in order to expose new surfaces for solvent penetration. However, this requires a great deal of technical effort and often special friction elements have to be used. Similar problems often arise in the production of suspensions.



   The aim is to propose a device in which, with separate dosing of the liquid components, the formation of agglomerates is prevented so that they can be processed with known screw machines.



   The device according to the invention for the continuous production of solutions and suspensions has a kneading device and a rotating mixing device connected upstream of the kneading device, which works at a higher speed than the kneading device.



  The mixing device can expediently have a rotating vertical shaft provided with mixing and crushing elements. An exemplary embodiment of the subject matter of the invention is shown schematically in the accompanying drawing.



   The device shown for continuously performing loosening processes has a kneading device 1 which has a screw 3 rotating in a housing 2, which is driven by means of a motor, not shown, arranged in a housing 4 via a gear. A mixing device 5 with its outlet nozzle 6 is connected to the filling opening of the housing 2. The mixing device has a shaft 8 which is arranged in a vertical housing 7 and is equipped with mixing and comminuting elements 9. The mixing and crushing elements 9 are distributed radially along the shaft. An electric motor 10, which is fastened to the upper end of the shaft 8 protruding from the housing 7, is used to drive the shaft 8.

   The shaft 8 rotates at several times higher speeds than the worm 3.



   The solids which are to be dissolved in a liquid are located in a container 11 and reach the mixing device by means of a conveyor belt or metering scale 12 through the filler neck 13.



  The filler neck 13 of the mixing device is arranged on the upper part of the housing 7. The pulverulent solids are captured in the housing 7 by the rotating, wing-like mixing and comminuting elements and set in a whirling motion. The liquid is introduced into the housing 7 from a container 14 by means of a line 15 via a metering pump 17. Instead of the single line 15, further lines branching off from the line 15 can be present, which open into the housing 7 at various points on the circumference. The wetted or pasted material is forced downwards or by gravity, whereby the relatively loose agglomerates are broken up.

   To support this effect, stator elements 16 can also be present in the housing 7, which interact with the mixing and comminuting elements 9. A mixture enters the kneading device 1 through the nozzle 6 and is further processed in this without difficulty.



   The device described is z. B. particularly suitable for the solution of polyacrylonitrile in dimethylformamide, acetyl cellulose in acetone, PVC in cyclohexanone, etc. and the production of suspensions z. B. from terephthalic acid and glycol, whereby the residence time of the product in the continuous compared to the batch-wise operating device can be significantly reduced. This improves the quality of the product and, for example, when polyacrylonitrile is dissolved in dimethylformide, the yellow coloration that otherwise occurs is significantly reduced or even completely prevented.
