Abstract
Der heutige Stand der Technik kennt zweigängige oder dreigängige Knet- und Mischblöcke mit flachem ausgebildetem Schneckenkamm. Um mit diesen herkömmlichen Knet- und Mischelementen einen guten Aufschmelz- und Mischprozess zu erzielen sind hohe Schneckenwellendrehzahlen notwendig, was aber schwerwiegende Nachteile im weiteren Prozessverlauf in der Mischmaschine nach sich zieht, insbesondere treten bei diesen hohen Schneckenwellendrehzahlen bei der austretenden Masse gegen ein Werkzeug, mit unterschiedlichem Druck, hohe Massetemperaturen auf, die zur Schädigung der zu verarbeitenden Masse führt, was nicht gewollt ist, aber in Kauf genommen werden muss. Der Aufgabe liegt nun zu Grunde, eine sehr gute Aufschmelz- und Mischleistung der zu verarbeitenden Massen zu erzielen, bei gleichzeitiger Schonung der zu verarbeitenden Massen. Die Lösung für diese Aufgabe ist in Anspruch 1 erklärt.The current state of the art knows zweigängige or three-course kneading and mixing blocks with flat trained Schneckenkamm. In order to achieve a good melting and mixing process with these conventional kneading and mixing elements high screw shaft speeds are necessary, but this entails serious disadvantages in the further course of the process in the mixing machine, in particular occur at these high worm shaft speeds in the exiting mass against a tool, with different pressure, high melt temperatures, which leads to damage to the processed mass, which is not wanted, but must be taken into account. The task is now based on achieving a very good melting and mixing performance of the masses to be processed, while sparing the masses to be processed. The solution to this problem is explained in claim 1.
Description
Die Erfindung betrifft eine mehrwellige kontinuierlich arbeitende Misch und Knetmaschinen fürplastifizierbare Massen mit zwei in einem Gehäuse drehenden Wellen, die jeweils ein die betreffende Welle umgebendes zylindrisches Gehäuseteil durchsetzen und Einzug – und Austragszonen sowie dazwischen mindesten eine Aufschmelz- und eine Mischzone aufweisen, wobei die Einzugs- und Austragszonen durch ineinandergreifende gleichsinnig drehende Förderelemente gebildet und in den Aufschmelz- und Mischzonen erfindungsgemäß gegenüberliegende Multimixprozesselemente angeordnet sind, deren Kanten beim Drehen mit geringem Spiel sowie auch größerem Spiel aneinander vorbeilaufen, wobei zur Bildung einer sich über die Multimixprozesselemente erstreckenden Kammer, die Kanten von dem sie umgebenden Gehäuseteil sowohl mit geringem Spiel wie auch größerem Spiel verschiedenen Abstand einhalten. Durch die erfindungsgemäße Oberflächenvergrößerung der oberen Kanten der Multimixprozesselemente, sowie deren insbesondere Viergängigkeit, besteht ein wesentlich längeren Kontakt zu den zu verarbeitenden Massen im Vergleich zu herkömmlichen zweigängigen Knet- und Mischelementen mit flachem Oberflächenkamm.The invention relates to a multi-shaft continuous mixing and kneading machines for plasticizable masses with two shafts rotating in a housing, each of which pass through a cylindrical housing part surrounding the shaft in question and have intake and discharge zones and at least one reflow zone and a mixing zone between them. and Austragszonen formed by interlocking co-rotating conveying elements and in the melting and mixing zones according to the invention opposite Multimixprozesselemente are arranged, the edges of which rotate when turning with little play as well as greater play, wherein forming an over the Multimixprozesselemente extending chamber, the edges of the they comply with surrounding housing part both with little play as well as larger game different distance. The inventive surface enlargement of the upper edges of the Multimixprozesselemente, as well as their particular Viergängigkeit, there is a much longer contact with the masses to be processed in comparison to conventional two-start kneading and mixing elements with a flat surface comb.
Eine derartige zweigängige Misch – und Knetmaschine ist aus der
Der Erfindung liegt die Aufgabe zugrunde, die Mischwirkung der eingangs genannten Maschine, sowie auch die Dispergierleistung erheblich zu steigern. Weiterhin sind Knetelemente bekannt, jedoch bisher nur in zwei- oder dreigängiger symmetrischer Ausführung mit einem glatten Schneckenkamm, bei der das zu verarbeitende Material durch einen engen Schneckenspalt gezwungen wird, was hohe Scherkräfte und Temperaturen hervorruft und nur mit einem großen erforderlichen Drehmoment zu bewältigen ist.The invention is based, to significantly increase the mixing effect of the aforementioned machine, as well as the Dispergierleistung the task. Furthermore, kneading elements are known, but so far only in two- or three-start symmetrical design with a smooth screw crest, in which the material to be processed is forced through a narrow screw gap, which causes high shear forces and temperatures and can be overcome only with a large torque required.
Der Abstand zwischen den Stegen dieser Knetelemente und auch der Abstand zur Gehäusewand beträgt je nach Schneckendurchmesser ca. 0,2 bis max. 1 mm. Zudem sind die Prozeßschneckenelemente der gleichsinnig drehenden Compounder zwei- oder maximal dreigängig ausgeführt.The distance between the webs of these kneading elements and the distance to the housing wall is depending on the screw diameter about 0.2 to max. 1 mm. In addition, the process screw elements of the co-rotating compounder are designed to be two or more than three turns.
Der neuartigen Erfindung der Multimixprozesselemente liegt insofern ferner die Aufgabe zu Grunde, die Mischwirkung bei gleicher Umdrehungsgeschwindigkeit der Schneckenwellen zu steigern, unter Berücksichtigung der besonderen Ausführungsvarianten der erfindungsgemäß zu verwendenden Multimixprozesselemente im Verhältnis zu zwei- oder dreigängigen Knetelementen. Die neuartigen Multimixelemente sind im wesentlichen so gestaltet, dass durch eine Kombination aus Symmetrie und Asymmetrie in Verbindung mit unterschiedlich gefrästen Oberflächen der Schneckenkämme und unterschiedlichem Schneckenspalt die gewünschten Aufschmelzzonen und Mischprozessen besser realisiert werden können, als mit herkömmlichen Knet- und Mischsystemen.The novel invention of the multimix process elements is also based on the object to increase the mixing effect at the same rotational speed of the screw shafts, taking into account the particular embodiments of the present invention to be used Multimixprozesselemente in relation to two- or three-speed kneading. The novel multi-mix elements are essentially designed so that the desired melting zones and mixing processes can be better realized by a combination of symmetry and asymmetry in connection with differently milled surfaces of the screw flights and different screw gap, as with conventional kneading and mixing systems.
Weiterhin liegt der neuartigen Erfindung der Multimixprozesselemente, die Aufgabe zu Grunde, die Mischwirkung zu steigern bei gleicher Umdrehungsgeschwindigkeit der Schneckenwellen, unter Berücksichtigung der besonderen Ausführungsvarianten der Multimixprozesselemente im Verhältnis zu zwei- oder dreigängigen Knetelementen, so wird durch die neuartigen Multimixprozesselemente die doppelte Knet- und Mischleistung bei der gleichen Umdrehungsgeschwindigkeit erreicht.Furthermore, the novel invention of the Multimixprozesselemente, the task is based on increasing the mixing effect at the same speed of rotation of the screw shafts, taking into account the particular embodiments of Multimixprozesselemente in relation to two- or three-speed kneading, so is the double-kneading and the new Multimixprozesselemente Mixing performance achieved at the same rotational speed.
Insbesondere wird die Dispergier- und Mischwirkung durch die asymmetrische Ausbildung der Multimixprozesselemente und die vergrößerte Oberfläche der Schneckenkämme der Multimixprozesselementen wesentlich erhöht, bei gleicher Schneckenwellendrehzahl im Vergleich zu herkömmlichen zweigängigen Knetblöcken.In particular, the dispersing and mixing action is substantially increased by the asymmetric design of the multi-mix process elements and the increased surface area of the screw combs of the multimix process elements, at the same screw shaft speed compared to conventional double-flighted kneading blocks.
Des Weiteren liegt der Erfindung die Aufgabe zu Grunde durch die beschriebene Ausführung der Multimixprozesselemente die mit den zu verarbeitenden Massen in Kontakt kommenden Oberflächen der Elemente so zu vergrößern, dass bei gleicher Länge der Multimixprozesselemente, im Vergleich zu herkömmlichen zweigängigen Knetblöcken eine wesentlich längerer Kontakt- und Verweildauer des zu verarbeitenden Materials in den neuartigen Multimixprozesselementen gegeben ist und somit die Misch- und Dispergierleistung wesentlich verbessert wird.Furthermore, the object of the invention is based on the described embodiment of the multimix process elements to increase the surfaces of the elements which come into contact with the masses to be processed in such a way that with the same length of the multimix process elements, a considerably longer contact and contact length compared to conventional double-kneaded kneading blocks Dwell time of the material to be processed is given in the novel Multimixprozesselementen and thus the mixing and dispersing performance is significantly improved.
Der Aufschmelzprozess der verschiedenen thermoplastischen Massen oder Ähnlichem, wird erfindungsgemäß durch die neuartig gestalteten Multimixprozesselemente entscheidend verstärkt und ist so auch bei geringen Schneckenwellendrehzahlen durch das vergrößerte Kammervolumen der neuartigen Erfindung der Multimixprozesselemente und der besonderen Oberflächen der Schneckenkämme auch in Verbindung mit der Asymmetrie möglich und daher von entscheidendem Vorteil gegenüber herkömmlichen Knetblöcken.The melting process of the various thermoplastic materials or the like, according to the invention significantly strengthened by the newly designed Multimixprozesselemente and is thus possible even at low screw shaft speeds by the increased chamber volume of the novel invention of Multimixprozesselemente and the special surfaces of the screw combs also in connection with the asymmetry and therefore of decisive advantage over conventional kneading blocks.
