Abstract
Description
Die Erfindung betrifft eine Homogenisator-Vorrichtung zum Dispergieren und/oder Homogenisieren flüssiger bis zähflüssiger Substanzen, mit einem Behälter mit einer oder mehr Öffnungen zum Einleiten der zu bearbeitenden Substanzen, der in einem zentralen Bereich seines Bodens eine Öffnung zum Zuführen der Substanzen in eine Bearbeitungseinheit aufweist, die zwei unabhängig voneinander antreibbare, konzentrisch angeordnete, kreisförmig ausgebildete Zahnkränze enthält, die über einen vorgegebenen Zwischenraum voneinander getrennt sind, wobei die Substanzen von einem zentralen Bereich durch den Zwischenraum in einen peripheren Bereich der Zahnkränze geleitet werden.The The invention relates to a homogenizer apparatus for dispersing and / or homogenizing liquid to viscous substances, with a container with one or more openings for introducing the substances to be processed, in a central Area of its bottom an opening to the Respectively the substances in a processing unit, the two independently drivable, concentrically arranged, circular trained Cassettes contains the above a predetermined gap are separated from each other, wherein the substances from a central area through the gap be directed into a peripheral region of the sprockets.
Vorrichtungen der eingangs genannten Art werden im Stand der Technik verwendet, um zähflüssige Substanzen unter hoher Drehzahl der betreffenden Zahnkränze zu homogenisieren. Mit den hohen Drehzahlen der Zahnkränze sind auf die zu bearbeitenden Substanzen einwirkende Zentrifugalkräfte verbunden, die eine Pumpwirkung hervorrufen, die wiederum zur Bildung eines die Substanzen fördernden Unterdruckes führt. Die bekannten Vorrichtungen weisen jedoch den Nachteil auf, dass mit Ausbildung des Unterdruckes sich in den Substanzen Kavitäten bilden, die einerseits ab einer kritischen Drehzahl auch bei weiterer Erhöhung der Drehzahl die Pumpleistung begrenzen und andererseits Korrosion und einen vorzeitigen Materialverschleiß begünstigen.devices of the type mentioned above are used in the prior art, viscous substances Homogenize at high speed of the respective sprockets. With the high speeds of the sprockets are connected to the substances to be processed acting centrifugal forces, which cause a pumping action, which in turn leads to the formation of a promoting the substances Negative pressure leads. However, the known devices have the disadvantage that with formation of the negative pressure cavities form in the substances, on the one hand from a critical speed even with further increase in Speed limit the pump power and on the other hand corrosion and promote premature wear of material.
Aufgabe der Erfindung ist es deshalb, eine Homogenisator-Vorrichtung zu schaffen, mit der bei einer hohen Effizienz eine Kavitätenbildung weitestgehend verhindert ist.task The invention is therefore to provide a homogenizer device with which in a high efficiency a cavity formation is largely prevented.
Für eine Vorrichtung der eingangs genannten Art wird diese Aufgabe dadurch gelöst, dass in der Bearbeitungseinheit zusätzlich eine Fördereinrichtung vorgesehen ist, die die Substanzen unter Druck in Richtung der Zahnkränze fördert.For a device of the aforementioned type, this object is achieved in that in the processing unit additionally a conveyor is provided, which promotes the substances under pressure in the direction of the sprockets.

Gemäß einer wichtigen bevorzugten Ausführungsform der erfindungsgemäßen Vorrichtung ist vorgesehen, dass die Zähne eines inneren Zahnkranzes zueinander in jeweils größerem Abstand angeordnet sind als die Zähne eines äußeren Zahnkranzes. Ein Zahn ist dabei vorzugsweise im Wesentlichen quaderförmig ausgebildet, wobei der Abstand zweier benachbarter Zähne eines Zahnkranzes kleiner bemessen ist als die Länge eines Zahns.According to one important preferred embodiment the device according to the invention is provided that the teeth an inner gear rim to each other at a greater distance are arranged as the teeth an outer sprocket. A tooth is preferably formed substantially cuboid, wherein the distance between two adjacent teeth of a sprocket smaller is measured as the length a tooth.
Gemäß einer weiteren wichtigen bevorzugten Ausführungsform der erfindungsgemäßen Vorrichtung ist vorgesehen, dass die beiden Zahnkränze gegenläufig antreibbar sind.According to one another important preferred embodiment of the device according to the invention is provided that the two sprockets are driven in opposite directions.
