Description

Mischmaschine Die Erfindung schlägt eine Mischmaschine vor, die dadurch gekennzeichnet ist, daß von zwei ineinander angeordneten Maschinenteilen der erste auf einer Oberfläche einen schraubenlinienförmig verlaufenden Gang aufweist, der mit einer Oberfläche des zweiten Maschinenteiles so zusammenwirkt, daß das Material während seines Vorschubes durch den Gang eine Durchmischung erfährt, und der zweite auf der Oberfläche mit Wenigstens einer im wesentlichen ringrörmigen Aussparung versehen ist, die dazu dient, daß während des Betriebes der Maschine das durch den schraubenlinienförmigen Gang hindurchtretende Material von dem durch den übrigen Teil der zusammenwirkenden Flächen begrenzten Strömungsweg abweichen kann.Mixing machine The invention proposes a mixing machine that thereby is characterized in that of two machine parts arranged one inside the other, the first has on one surface a helical passage which cooperates with a surface of the second machine part so that the material undergoes mixing during its advance through the passage, and the second on the surface with at least one substantially annular recess is provided, which serves that during the operation of the machine by the helical passage of material passing through the remainder Part of the interacting surfaces can deviate from the limited flow path.

Ein Ausführungsbeispiel wird anhand der Zeichnung näher erläutert.An exemplary embodiment is explained in more detail with reference to the drawing.

Die einzige Figur zeigt eine geschnittene Seitenansicht einer Einzelheit der Mischmaschine.The single figure shows a sectional side view of a detail the mixer.

Die Mischmaschine weist einen als Schnecke 1 gestalteten Rotor aufj der in einem durch eine Trommel 2 gebildeten Gehäuseständer drehbar gelagert ist. In der Fläche 5 der Trommel 2, mit der die schraubengewindeartige Fläche 4 der Schnecke 1 zusammenwirkt, ist wenigstens eine im wesentlichen ringförmige Aussparung 5 vorgesehen.The mixing machine has a rotor designed as a screw 1 which is rotatably mounted in a housing stand formed by a drum 2. In the surface 5 of the drum 2 with which the screw thread-like surface 4 of the worm 1 cooperates, at least one substantially annular recess 5 is provided.

Während des Betriebes der Maschine wird das Material durch die Rotation der Schnecke 1 in ihrem Schraubenliniengang vorgeschoben, wobei es gemischt wird. Das Material neigt zu einer schichtweisen Lagerung, wie sie in der Zeichnung bei 6A bis 6D angedeutet ist und die Durchmischung erfolgt in jeder Lage. Der Materialaustausch von Lage zu Lage ist jedoch im allgemeinen gering und nur im Bereich der Aussparung bzw. Aussparungen 5 merklicher, weil das Material von seinem durch den übrigen Teil der zusammenwirkenden Flächen von Schnecke und Trommel begrenzten Strömungsweg abweichen kann.While the machine is in operation, the material is rotated the screw 1 is advanced in its helical flight, whereby it is mixed. The material tends to be stored in layers, as shown in the drawing 6A to 6D is indicated and the mixing takes place in every position. The exchange of materials however, from position to position is generally small and only in the area of the recess or recesses 5 more noticeable because the material from its through the remaining part of the interacting surfaces of the screw and bowl deviate from the limited flow path can.

Es tritt durch die Aussparung 5 hindurch und aufgrund des Druckgefälles über die Schneckenflanken hinweg, wobei die Schichtlagen aufgebrochen werden und der Mischvorgang verbessert wird.It passes through the recess 5 and due to the pressure gradient over the screw flanks, the layers being broken up and the mixing process is improved.

Die Anordnung kann so getroffen sein, daß die Schnecke feststeht und sich die Trommel dreht, daß sowohl die Schnecke als auch die Trommel sich drehen oder daß beide Teile feststehend vorgesehen sind, und das Material durch den Schneckengang hindurchgedrückt wird.The arrangement can be made so that the screw is fixed and the drum rotates so that both the screw and the drum rotate or that both parts are provided stationary, and the material through the screw flight is pushed through.

Die Mischmaschine kann ein Extruder oder eine andere Mischmaschine sein, bei der ein Medium mit unterschiedlichen Eigenschaften und/oder Zuständen innerhalb desselben oder eine Mehrzahl von Medien mit unterschiedlichen Eigenschaften#oder Zuständen in einen Zustand größerer Gleichförmigkeit als vorher überführt wird bzw.The mixing machine can be an extruder or other mixing machine be in the case of a medium with different properties and / or states within the same or a plurality of media with different properties # or States are transformed into a state of greater uniformity than before or

werden, unabhängig davon, ob dies der Hauptzweck der Einrichtung oder eine Nebenwirkung ihres Betriebes ist.regardless of whether this is the main purpose of the establishment or is a side effect of their operation.

Die unterschiedlichen Eigenschaften oder Zustände können verschiedene Aggregatzustände, Partikel, Größe oder Gestalt, Temperdur, Dichte und dgl. sein.The different properties or states can be different Physical states, particles, size or shape, temperature, density and the like. Be.

Außer einer guten Durchmischung des Materiales bewirkt die Maschine eine gute Wärmeübertragung, die ihre Hauptfunktion darstellen kann.In addition to a good mixing of the material, the machine causes good heat transfer, which can be its main function.
