Description
Einrichtung zum Mischen und/oder Zerkleinern von pulverförmigem und/oder flüssigem Gut Die Erfindung bezieht sich auf eine Einrichtung zum Zerkleinern, von pulverförmigem Gut und zum Mischen miteinander oder mit Flüssigkeit in einem vorzugsweise kesselförmigen Behälter, auf dessen Boden ein aus aufrechtstehenden Zerkleinerungswerkzeugen gebildeter feststehender Werkzeugkranz vorgesehen ist, in dem ein Flügelrad mit hoher Drehzahl umläuft und das Gut gegen die Zerkleinerungswerkzeuge des Werkzeugkranzes schleudert, wobei zwischen dem Werkzeugkranz und dem Umfang des Flügelrades ein schmaler Ringspalt vorhanden ist. Device for mixing and / or grinding powdery and / or Liquid material The invention relates to a device for comminuting, of powdery material and for mixing with each other or with liquid in one preferably Kettle-shaped container, on the bottom of which is made up of upright crushing tools formed fixed tool rim is provided in which an impeller with rotates at high speed and the material against the shredding tools of the tool ring throws, with a between the tool rim and the circumference of the impeller there is a narrow annular gap.
Es sind bereits derartige Misch- oder Zerkleinerungsvorrichtungen bekannt, bei denen ein Flügelrad in einem Werkzeuígkranz rotiert, bei denen aber eine Verstellmöglichkeit zwischen diesen beiden Teilen und damit eine Möglichkeit zur Änderung der Breite des Ringspaltes zwischen denselben nicht vorhanden ist. There are already such mixing or comminuting devices known, in which an impeller rotates in a tool rim, but in which an adjustment between these two parts and thus a possibility to change the width of the annular gap between the same does not exist.
Dadurch ist der Anwendungsbereich dieser Einrich-- tungen insofern beschränkt, als eine Anpassung der Breite des Ringspaltes an das jeweils zu verarbeitende Gut und an den gewünschten Misch- bzw. Zerkleinerungseffekt nicht möglich ist. As a result, the scope of these facilities is insofar limited, as an adaptation of the width of the annular gap to the respective to be processed Good and the desired mixing or crushing effect is not possible.
Zwar ist bei einer weiteren bekannten Mischvorrichtung am Außenumfang des Werkzeugkranzes ein verstellbarer Schlitz vorgesehen. Dieser Schlitz befindet sich jedoch zwischen zwei Teilen, die keine Relativbewegung gegeneinander ausführen. Da deshalb eine Zerkleinerung des Gutes an dieser Stelle nicht oder zumindest nicht in dem erforderlichen Maße erfolgen kann, ist zu befürchten, daß sich der Schlitz während des Betriebes durch Gutteilchen, die durch die Schleuderwirkung beim Austritt aus dem Flügelrad und beim Eintritt in den Werkzeugkranz nicht genügend zerkleinert werden, zusetzt. It is true that in another known mixing device on the outer circumference an adjustable slot is provided on the tool rim. This slot is located however, between two parts that do not move relative to each other. As a result, the material is not or at least not shredded at this point can be done to the extent necessary, it is to be feared that the slot during operation by good particles caused by the centrifugal effect when exiting not sufficiently shredded from the impeller and when entering the tool rim become, clogs.
Diese Nachteile mit einfachen Mitteln zu vermeiden ist die Aufgabe der Erfindung. Danach wird bei einer Einrichtung der eingangs genannten Art vorgeschlagen, den Werkzeugkranz an seinem Innenumfang und das Flügelrad an seinem Außenumfang konisch auszubilden und eines dieser Teile gegenüber dem anderen zur Änderung der Breite des Ringspaltes in axialer Richtung verstelllbar anzuordnen. The task is to avoid these disadvantages by simple means the invention. It is then proposed for a facility of the type mentioned at the outset that the tool rim on its inner circumference and the impeller on its outer circumference to be conical and one of these parts compared to the other to change the Arrange the width of the annular gap adjustable in the axial direction.
Bei den sogenannten Kolloidmühlen ist es allerdings bereits bekannt, die Zerkleinerungswerkzeuge konisch auszubilden und den Mahlspalt durch gegenseitiges axiales Verschieben der konischen Zerkleinerungswerkzeuge zu ändern. In the so-called colloid mills, however, it is already known the comminution tools to be conical and the grinding gap by mutual to change the axial movement of the conical grinding tools.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstanldes dargestellt, und zwar zeigt Fig. 1 einen Länlgsschnitt durch die erfindungsgemäß vorgeschlagene Einrichtung und Fig. 2 einen Schnitt nach der Linie II-II der Fig. 1. The drawing shows an embodiment of the subject matter of the invention shown, namely Fig. 1 shows a longitudinal section through the invention proposed device and FIG. 2 shows a section along the line II-II of FIG. 1.
Ein kesselförmiger Behälter 1 ist an Bolzen 2 um eine waagerechte Achse schwenkbar in Lagerböcken 3 aufgehängt. Unter dem Behälter 1 ist ein Antriebsmotor 4 befestigt, dessen Welle 5 durch den Boden des kesselförmigen Behälters 1 in diesen hineinragt. Die Welle 5 ist im Behälterboden auf nicht näher dargestellte Weise abgedichtet. Auf der Welle 5 des Antriebsmotors 4 ist ein Flügelrad 6 befestigt, dessen einzelne Flügel an ihrem Umfang durch einen Ring 7 derart abgedeckt sind, daß eine mittlere Eintrittsöffnung 8 entsteht, in die das zu bearbeitende Gut eintreten kann, während es am Umfang des Flügelrades 6 aus demselben herausgeschleudert wird. Auf dem Boden des Behälters 1 ist ein Werkzeugkranz 9 befestigt, auf dem die Zerkleinernngswerkzeuge 10 befestigt sind. Zwischen dem Werkzeugkranz 9 mit den Zerkleinerungswerkzeugen 10 und dem Flügelrad 6 ist ein Ringspalt 11 vorgesehen. A kettle-shaped container 1 is attached to bolts 2 around a horizontal one Axis pivotably suspended in bearing blocks 3. Under the container 1 is a drive motor 4 attached, the shaft 5 through the bottom of the kettle-shaped container 1 in this protrudes. The shaft 5 is in the container bottom in a manner not shown sealed. An impeller 6 is attached to the shaft 5 of the drive motor 4, the individual wings of which are covered on their circumference by a ring 7 in such a way that that a central inlet opening 8 is created, into which the material to be processed enter can, while it is thrown out of the same on the periphery of the impeller 6. On the bottom of the container 1, a tool ring 9 is attached, on which the comminuting tools 10 are attached. Between the tool rim 9 with the shredding tools 10 and the impeller 6, an annular gap 11 is provided.
Der Werkzeugkranz 9 mit den Zerkleinerungswerkzeugen 10 ist an seinem inneren Umfang konisch ausgebildet. Ebenso ist auch das Flügelrad 6 an seinem Außenumfang konisch ausgebildet. Gleichzeitig sind Werkzeugkranz 9 und Flügelrad 6 gegeneinander in nicht näher dargestellter Weise in axialer Richtung verstellbar, so daß die Breite des Ringspaltes 11 verändert werden kann. The tool rim 9 with the shredding tools 10 is on his conical inner circumference. The impeller 6 is also on its outer circumference conical. At the same time, the tool rim 9 and the impeller 6 are against each other adjustable in the axial direction in a manner not shown, so that the width of the annular gap 11 can be changed.
Für den kontinuierlichen Betrieb der Einrichtung ist ein Einfüllrohr 12 vorgesehen, welches bis vor die Eintrittsöffnung 8 des Flügelrades 6 in den Behälter 1 hineinragt, während ein Absaugrohr 13 bis unter die Oberfläche des zu bearbeitenden Gutes in den Behälter 1 hineinragt. For the continuous operation of the device there is a filler pipe 12 is provided, which up to the inlet opening 8 of the impeller 6 in the container 1 protrudes, while a suction tube 13 extends below the surface of the to be processed Good protrudes into container 1.
Die Wirkungsweise der Einrichtung ist die folgende: Das zu mischende und zu zerkleinernde Gut gelangt durch die Eintrittsöffnung 8 zwischen die einzelnen Flügel des mit hoher Drehzahl umlaufenden Flügelrades 6 und wird durch die Zentrifugalkraft aus diesen herausgeschleudert. Dabei gelangt es zum Teil in den Ringspalt 11 zwischen Flügelrad 6 und die Zerkleinerungswerkzeuge 10 des Werkzeugkranzes 9, wo es zerrieben wird, während ein anderer Teil gegen die Zerkleinerungswerkzeuge 10. geschleudert und an diesen zerspalten wird. Nach Austritt aus dem Werkzeugkranz erfährt das Gut, welches gleichzeitig in eine rotierende Bewegung in Drehrichtung des Flügelrades versetzt wird, eine Umlenkung durch die Kesselwand und steigt in Richtung der Pfeile 14 zur Oberfläche auf. The way the device works is as follows: The one to be mixed and the material to be shredded passes through the inlet opening 8 between the individual The wing of the high-speed rotating impeller 6 and is driven by centrifugal force thrown out of these. In doing so, some of it gets into the annular gap 11 between Impeller 6 and the crushing tools 10 of the tool rim 9, where it is ground while another part is thrown against the grinding tools 10. and is split at these. After exiting the tool ring, the good experiences which simultaneously in a rotating movement in the direction of rotation of the impeller is offset, a diversion through the boiler wall and rises in the direction of the arrows 14 to the surface.
An der Oberfläche wird das Gut erneut umgelenkt und in Richtung der Pfeile 15 erneut vom Flügelrad 6 angesaugt. Bei diesem Kreislauf entsteht eine Strömung zwischen aufsteigendem und abfallendem Gut, die durch die Pfeile 16, 17 angedeutet ist. Das Absaugrohr 13 taucht im Bereich dieser Grenzströmung, in der ein besonders starker Mischeffekt erzeugt wird, in die Oberfläche des Gutes ein und saugt das zerkleinerte und gemischte Gut aus dem Behälter 1 ab.On the surface, the material is deflected again and in the direction of the Arrows 15 sucked in again by the impeller 6. A current is created in this cycle between rising and falling material, which is indicated by the arrows 16, 17 is. The suction pipe 13 is immersed in the area of this boundary flow, in which a particularly strong mixing effect is created in the surface of the good and sucks it Shredded and mixed material from container 1.
Die Zerkleinerungswerkzeuge 10 haben zweckmäßig einen rechteckigen Querschnitt und weisen auf der dem Flügelrad6 zugekehrten Seite Schneidkanten auf. Es können aber auch Zerkleinerungswerkzeuge mit anderen Querschnitten, beispielsweise mit rundem, halbrundem oder tragflügelartigem Querschnitt, zur Anwendung gelangen. Ebenso ist es macht erforderlich, daß der Antriebsmotor unmittelbar am Behälterboden aufgehqängt ist. Es ist vielmehr auch möglich, den Antriebsmotor seitlich des Behälters an oder neben demselben anzuordnen und das Flügelrad beispielsweise durch Keilriemen anzutreiben. The comminuting tools 10 expediently have a rectangular shape Cross-section and have cutting edges on the side facing the impeller 6. However, shredding tools with other cross-sections can also be used, for example with a round, semicircular or airfoil-like cross-section, are used. It is also necessary that the drive motor is directly on the bottom of the container is hung up. Rather, it is also possible to have the drive motor on the side of the container to be arranged on or next to the same and the impeller, for example, by V-belt to drive.
