Kontinuierliche Löeegro@@s@@ sind mittels Schneckenmaschinen verschiedener @@@ert d@@@@f@hrbar. Dabei wurdfe jedoch als nachteilig @@pfunden, dase bein Desieren im Einfüllbereich oft rössere Appl@@@@@te ents@@@@@, die vom Lösemittel umhüllt werden und den weiteren Lössver@@@@ erschweren. Nur durch Aufbringen von relativ grossen Sch@@@@@@@@@ sind die @@llertartigen Mäute absurei@@@, @@ dadurch @@@@ Oberflächen für die Lösenittelpenetration frei zu l@@@@. @@@@ ist jedoch grosser technischer Aufwend @@tig und @@t @@@@@@ @@@@ielle Reibel@@@@te Anwendung finden. Bei der @@@@tellung von Susp@@@ionen stellen sich oft ähnliche Prebl@@@.Continuous Löeegro @@ s @@ are different by means of screw machines @@@ ert d @@@@ f @ hrbar. In doing so, however, @@ pounds were detrimental, that is when desiring in the filling area often larger appl @@@@@ te ents @@@@@, which are enveloped by the solvent and complicate the further Lössver @@@@. Just by applying relative big Sch @@@@@@@@@ are the @@ llert-like skins absurei @@@, @@ thereby @@@@ surfaces for solvent penetration free to l @@@@. However, @@@@ is more technical Aufwend @@ tig and @@ t @@@@@@ @@@@ ielle Reibel @@@@ te apply. At the @@@@ tellung Susp @@@ ions often have similar Prebl @@@.
Erfindungsgemäse wird @@@@@tr@@t, eine Einrichtung vorzuschlagen, bei welcher bei separat@@ Dosierung der Flüssigkeitskomponenten die Bildung von Agglemeraten verhindert wird, so dass diese mit bekannten Schneckenmaschinen verarbeitet werden können.According to the invention, @@@@@ tr @@ t will propose a device in which, with separately @@ dosing of the liquid components, the formation of Agglemeraten is prevented so that this with known screw machines can be processed.
Die erfindungsgemässe Einrichtung zum kontinuierlichen Herstellen von Lösungen und Suspensionen welt eine Knetvorrichtung und eine der Knetvorrichtung vorgeschaltete rotierende Mischvorrichtung auf, welch nilt einer Möheren Drehzahl als die Knetvorrichtung arbeitet. Zweckmässigerweise kann die Mischvorrichtung als Mischturbine ausgebildet sein, welche eine rotierende mit Misch-und Zerkleinerungsorganen versehene vertikale Welle aufweist.The device according to the invention for continuous production of solutions and suspensions world one kneading device and one of the kneading device upstream rotating mixing device, which nilt a higher speed as the kneader works. Conveniently, the mixing device as Mixing turbine can be designed, which has a rotating with mixing and comminuting elements has provided vertical shaft.
Auf bot liegender Zeichnung ist ein @usführungsbeispiel des zrfindungsgegenstandes schematisch dargestellet.The drawing on offer is an example of the object of the invention shown schematically.
Die dargestellte @inrichtung mut kontinuierlichen Durchführen von Löseprozessen weist eine Knetvorrichtung 1 auf, welche eine in einem Gehäuse 2 rotierende schnecke @ besitzt, die mittels eines in einem Gehäuse 4 angeordneten nicht darge@@llten Motors über ein Cetr@@@s angetrieben wird. An die Einfüllöffnung des Gehäus@@ 2 ist eine @ischvorrichtung 5 itt ihrer Austrittsdüse 6 angeschlossen. Die Mischvorrichtung weist eine in einem vertikalen Gehäuse 7 angeordnete Welle 8 auf. die itt @isch- und @erkleinerungsorganen 9 ausq@@üstet ist. Die @isch- und Zerkleinerungsorgane 9 sind entlang der Welle radial verteilt. Zum Antrieb der Welle @ dient ein Elektromotor 10. welcher an obere aus den Gehäuse 7 herzusra@enden Ende der Welle 8 befestigt ist. Die welle 8 rotiert mit mehrfach erhöhten Drehzahlen ge@enüber der Schnecke 3.The device shown must be carried out continuously Dissolving processes has a kneading device 1, which is rotating in a housing 2 worm @, which by means of a arranged in a housing 4 is not shown @@ llten Motor is driven via a Cetr @@@ s. To the filling opening of the housing @@ 2 an @ischvorrichtung 5 is connected to its outlet nozzle 6. The mixing device has a shaft 8 arranged in a vertical housing 7. the itt @ isch- and @reducing organs 9 ausq @@ üstet. The @ish and crushing organs 9 are distributed radially along the shaft. An electric motor is used to drive the shaft @ 10. which is attached to the upper end of the shaft 8 from the housing 7 herzusra @ ends is. The shaft 8 rotates at multiple increased speeds over the worm 3.
Die Feststoffe, welche in einer Flüssigkeit gelnst werden sollen, befinden sich in einen Behälter 11 und gelangen mittels $eines $@brderbandes oder Desierwaage 12 durch den Einfüllstutzen 13 in die Mischvorrichtung. Der @infüllstutzen 13 der Mischvorrichtung ist am oberen Teil des Gehauses 7 angeordnet. Die pulverförmigen Feststoffe werden il Gehause 7 von den rotierenden flügelertigen Misch- und Zerkleinerungsorganen erfasst und in wirbelnde Bewegung versetzt. t?ie Flüssickeit wlrd au einen Behalter 14 mittels einer Leitung 15 tiber eine Dosierpumpe 17 in das Gehäuse 7 eingeführt. an Stelle der einzigen Leitung 15 Konnen weitere aus der Leitung 15 abzweigende Leitungen vorhanden sein, die an verschiedenen Umfangsstellen in des Gehause 7 münden, Das benetzte oder angeteigte Material wird @wangsi@ufig oder durch die Schwerkraft nach unten gefördert, wobei die relativ lockeren Agglomerate zerschlagen werden. Zur Unterstützung dieser wirkung können ie Gehause 7 noch @tatorelemente 14 vorhanden sein, welche mit den Misch- und Zerkleinerungsorganen 9 zusa@@@@wirken. Durch die Düse 6 tritt eine Mischung in die Knetvorrichtung 1 ein, welche in dieser ohne schwierigkeiten weite@ vererbeitet wird.The solids that should be applied in a liquid, are in a container 11 and get by means of a $ @ brderbandes or Desierweigher 12 through the filler neck 13 into the mixing device. The @ filler neck 13 of the mixing device is arranged on the upper part of the housing 7. The powdery Solids are removed from the housing 7 by the rotating, ready-to-use mixing and comminuting elements captured and set in swirling motion. The liquid will be in a container 14 is introduced into the housing 7 by means of a line 15 via a metering pump 17. Instead of the single line 15, additional ones branching off from the line 15 can be used There are lines that open into the housing 7 at various points on the circumference, The wetted or pasted material becomes @wangsi @ ufig or by gravity conveyed downwards, the relatively loose agglomerates being broken up. To support this effect, the housing 7 can also be used with gate elements 14 which act together with the mixing and crushing organs 9. Through the Nozzle 6 a mixture enters the kneading device 1, which in this without difficulties wide @ is processed.
Die beschriebene Einrichtung ist z.B. beonders geeignet zur Lösung von Poly@orylitril in Dimethylfornamid, von Acetyl-Cellulose in Aceto@, @@@ in cyclohexanon etc. wtd Herstellung von Suspensi@@en z.B. aus Therephtalsäure und Glykol, wobei die Verweilseit des Produktes in der koptinuierlichen gegenüber der char@@@weise arbeitenden Einrichtung wesentlich herabgesetzt werde . Dadurch wird die Qu@lität des Produktes verbessert und beispielsweise bei der $Lösung von polyacrylnitr@@ in Dimethylfornamid die sonst auftretende Gel wesentlich herabgesetzt oder sogar ganz verhindert.bfärtungThe device described is, for example, particularly suitable for the solution of poly (@ orylitrile in dimethylformide), of acetyl cellulose in aceto @, @@@ in cyclohexanone etc. wtd Production of suspensions e.g. from terephthalic acid and glycol, whereby the dwell time of the product in the cop-continuous opposite the char @@@ way working facility will be significantly reduced. This increases the quality of the product and, for example, in the $ solution of polyacrylnitr @@ in dimethylfornamide the otherwise occurring gel is significantly reduced or even completely prevented
