Description
Die vorliegende Erfindung betrifft eine Mischvorrichtung anorganischer und/oder organischer Schüttgüter oder pastöser Massen gemäß dem Oberbegriff des Anspruches 1, sowie ein Verfahren zum Mischen eines Schüttgutes oder einer pastösen Masse zu einem extrudierfähigen Material.The present invention relates to a mixing device of inorganic and / or organic bulk materials or pasty materials according to the preamble of claim 1, and to a method for mixing a bulk material or a pasty mass into an extrudable material.
Aus dem Stand der Technik ist bekannt, bei der Herstellung von Produkten aus thermoplastischen Polymeren, diese zur Einstellung bestimmter Produkteigenschaften in der Regel mit Zusatzstoffen zu beaufschlagen. So wird beispielsweise in der Polyvinylchlorid(PVC)-Bearbeitung nahezu ausschließlich mit diskontinuierlichen Mischsystemen gearbeitet, mit welchen über eine Heiz-/Kühlanordnung ein allgemein unter „Dry Blend” bekanntes Gemisch hergestellt wird. Als Dry Blend, eine Trockenmischung, wird beispielsweise ein Gemisch eines Kunststoffpulvers mit Zuschlagstoffen, Flüssigkeiten wie z. B. Weichmacher oder anderen Alternativen bezeichnet. Die Bezeichnung ist vor allem bei der Verarbeitung von PVC üblich. Die Herstellung einer solchen sogenannten Trockenmischung erfolgt üblicherweise in warmen Zustand bei Temperaturen zwischen 110 und 120°C. Dabei wird beispielsweise der Weichmacher vollständig vom PVC absorbiert, sodass nach der Wiederabkühlung der Trockenmischung eine rieselfähige Mischung entsteht.It is known from the prior art, in the production of products made of thermoplastic polymers, to apply these additives to adjust certain product properties as a rule. Thus, for example, working in polyvinyl chloride (PVC) processing almost exclusively with discontinuous mixing systems, with which via a heating / cooling arrangement a generally known "dry blend" mixture is prepared. As a dry blend, a dry blend, for example, a mixture of a plastic powder with additives, liquids such. As plasticizers or other alternatives. The term is common especially in the processing of PVC. The preparation of such a so-called dry mixture is usually carried out in a warm state at temperatures between 110 and 120 ° C. In this case, for example, the plasticizer is completely absorbed by the PVC, so that after the re-cooling of the dry mixture, a free-flowing mixture is formed.
Die Herstellung der für Extrusionsprozesse benötigten Trockenmischungen erfolgt nahezu ausschließlich chargenweise und erfordert einen hohen Aufwand an Energie, Zeit und Maschinentechnik.The preparation of the dry mixtures required for extrusion processes takes place almost exclusively in batches and requires a great deal of energy, time and machine technology.
Versuche, solche mit Zuschlagstoffen wie Weichmacher im Extrusionsprozess direkt zuzugeben, haben sich als nicht praktikabel herausgestellt, da für die Aufnahme durch das Polymer und deren Homogenisierung eine erhebliche Verweilzeit im Extruder benötigt wird.Attempts to directly add those with additives such as plasticizers in the extrusion process, have turned out to be impractical, since for the absorption by the polymer and their homogenization a significant residence time in the extruder is needed.
Durch die Ersetzung des oben beschriebenen konventionellen Mischprozesses durch einen Inline-Prozess könnten viel Platz, Energie und Verarbeitungszeit eingespart werden. So ist aus der
Problematisch ist hier, dass bei dieser Apparatur auf Grund der hohen Viskosität der Voremulsion die zu geringe Förderkapazität dieser Apparatur zu Produkt-Rückstauungen oder zur örtlichen Überhitzung der Emulsion führen kann. Dieses Problem erhöht sich mit zunehmender Temperatur noch, wenn die zu mischenden Substanzen mit steigender Temperatur an Klebrigkeit zunehmen. Ein stabiler Betrieb einer solchen Mischapparatur ist somit nicht gewährleistet.The problem here is that in this apparatus due to the high viscosity of the pre-emulsion, the insufficient delivery capacity of this apparatus can lead to product backwater or local overheating of the emulsion. This problem increases with increasing temperature even if the substances to be mixed increase in tack as the temperature increases. A stable operation of such a mixing apparatus is thus not guaranteed.
Aus der
Da in der Praxis sowohl der Einsatz hoher Gehalte an schlecht fließenden, Brücken bildenden Substanzen und Flüssigkeiten als auch hohe Temperaturen gängige Praxis sind, ist dieses System in seinem Einsatzspektrum stark begrenzt.Since in practice both the use of high contents of poorly flowing bridging substances and liquids and high temperatures are common practice, this system is very limited in its range of applications.
Die bei der Friktion entstehenden hohen Temperaturen werden in der Regel nicht nur benötigt, um eine homogene PVC-Mischung mit Additiven und Flüssigkeiten zu gewährleisten, sondern auch, um den Energieverbrauch während des direkt nachfolgenden Aufschmelzvorganges zu reduzieren.The high temperatures created during the friction are usually not only needed to ensure a homogeneous PVC mixture with additives and liquids, but also to reduce the energy consumption during the direct subsequent melting process.
Aufgabe der vorliegenden Erfindung ist es, einen Mischvorrichtung sowie ein Verfahren zum Mischen eines Schüttgutes oder einer pastösen Masse zu einem extrudierfähigen Material bereit zu stellen, dass eine dauerhafte kontinuierliche Fahrweise bei geringen Energiekosten sowie geringer Verarbeitungszeit ermöglicht.Object of the present invention is to provide a mixing device and a method for mixing a bulk material or a pasty mass to an extrudable material that allows a continuous continuous operation with low energy costs and low processing time.
Diese Aufgabe wird durch eine Mischvorrichtung mit den Merkmalen des Anspruches 1 sowie durch ein Verfahren mit den Merkmalen des Anspruches 16 gelöst.This object is achieved by a mixing device having the features of claim 1 and by a method having the features of
Die erfindungsgemäße Mischvorrichtung weist einen Mischbehälter mit einer Mischkammer auf, ein drehbares Außenmisch- und Förderwerkzeug mit Scher- und Förderelementen sowie ein drehbares Innenmisch- und Förderwerkzeug mit Scher- und Förderelementen, wobei die Mischkammer eine sich an eine Mischzone in Förderrichtung anschließende Kompressionszone sowie eine sich an die Kompressionszone anschließende Austragzone aufweist. The mixing device according to the invention comprises a mixing container with a mixing chamber, a rotatable external mixing and conveying tool with shear and conveying elements and a rotatable internal mixing and conveying tool with shear and conveying elements, wherein the mixing chamber adjoining a mixing zone in the conveying direction compression zone and a Having on the compression zone subsequent discharge zone.
Mit der erfindungsgemäßen Mischvorrichtung ist ein stabiler, konstanter Produktionsbetrieb ermöglicht, durch den in einem Prozess drastische Einsparungen an Platz, Energieverbrauch sowie Verarbeitungszeit ermöglicht sind. Auch die Investitionskosten für Maschinen, Anlagen und Gebäude lassen sich deutlich reduzieren. Des Weiteren wird das Materialhandling vereinfacht und Entmischungen, wie sie im Batch-Mischprozess vorkommen können, werden hier vermieden. Auch der Personalaufwand zum Bedienen einer solchen Mischvorrichtung und zum Betreiben des erfindungsgemäßen Verfahrens benötigt weniger Personal als bei der Batch Fahrweise.With the mixing device according to the invention, a stable, constant production operation is made possible by which in a process drastic savings in space, energy consumption and processing time are possible. The investment costs for machines, plants and buildings can be significantly reduced. It also simplifies material handling and eliminates the segregation that can occur in the batch mixing process. Also, the personnel costs for operating such a mixing device and for operating the method according to the invention requires less staff than in the batch mode.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Gemäß einer bevorzugten Ausführungsvariante sind die Misch- und Förderwerkzeuge als zwei gleich und gegenläufig betreibbare Misch- und Förderwerkzeuge ausgebildet.According to a preferred embodiment variant, the mixing and conveying tools are designed as two equal and in opposite directions operable mixing and conveying tools.
Durch die einstellbaren Drehrichtungen können stets konstante Produktionsbetriebe gewährleistet werden, selbst bei Substanzen, welche schlecht fließend, Brücken bildend oder klebrig sind.The adjustable direction of rotation ensures constant production, even with substances that are poorly flowing, bridging or sticky.
Gemäß einer weiteren Ausführungsvariante ist die Austrittszone als Stopfwerk ausgebildet, durch das eine Radialbewegung des Mischgutes reduziert und durch eine Axialbewegung das Mischgut in den Extruder hinein gefördert wird.According to a further embodiment variant, the exit zone is designed as a stuffing unit, by which a radial movement of the mixed material is reduced and the mixed material is conveyed into the extruder by an axial movement.
Gemäß einer weiteren bevorzugten Ausgestaltung der Mischvorrichtung sind die Scherelemente des Außenmisch- und Förderwerkzeuges winklig zu den Scherelementen des Innenmisch- und Förderwerkzeuges ausgerichtet. In einer besonders bevorzugten Ausführungsvariante sind diese Scherwinkel der zusammenwirkenden Scherelemente verstellbar ausgebildet. Zusätzlich ist gemäß einer weiteren Ausgestaltung der Mischvorrichtung das Außenmisch- und Förderwerkzeug und/oder das Innenmisch- und Förderwerkzeug axial verschiebbar ausgebildet, um die Spaltbreite zwischen den Scherelementen verändern zu können, um die Dispergierung zu beeinflussen und somit ein Auftreten von lokalen Temperaturspitzen bei der Durchmischung wirksam zu vermeiden.According to a further preferred embodiment of the mixing device, the shearing elements of the external mixing and conveying tool are aligned at an angle to the shearing elements of the internal mixing and conveying tool. In a particularly preferred embodiment, these shear angles of the interacting shear elements are adjustable. In addition, according to a further embodiment of the mixing device, the external mixing and conveying tool and / or the internal mixing and conveying tool formed axially displaceable to change the gap width between the shear elements can to influence the dispersion and thus an occurrence of local temperature peaks during mixing to avoid effectively.
Bei dem erfindungsgemäßen Verfahren zum Mischen eines Schüttgutes oder einer pastösen Masse zu einem extrudierfähigen Material wird zunächst das zu mischende Schüttgut oder die pastöse Masse in die Mischzone der oben beschriebenen Mischvorrichtung eingezogen, dass Mischgut wird dann homogenisiert, anschließend dispergiert bzw. geliert und vor der Weitergabe in den Extruder zunächst komprimiert und anschließend gestopft, wobei sämtliche Verfahrensschritte kontinuierlich in einem Temperaturzyklus durchgeführt werden. Durch das erfindungsgemäße Verfahren ist es nunmehr ermöglicht, ein extrudierfähiges Material durch Mischen eines Schüttgutes oder einer pastösen Masse herzustellen, ohne die energie-, zeit- und maschinentechnisch aufwändigen Verfahrensschritte eines Batchprozesses, wie eingangs beschrieben, auf sich nehmen zu müssen.In the method according to the invention for mixing a bulk material or a pasty mass into an extrudable material, the bulk material or the pasty mass to be mixed is first drawn into the mixing zone of the mixing device described above, that the mixture is then homogenized, then dispersed or gelled and before passing initially compressed in the extruder and then stuffed, all the steps are carried out continuously in a temperature cycle. By the method according to the invention it is now possible to produce an extrudable material by mixing a bulk material or a pasty mass, without having to take on the energy, time and machine technically complex process steps of a batch process, as described above.
