Description

Die Erfindung bezieht sich auf einen Rührwerkzeug zum Herstellen eines flüssigen, gegebenenfalls gasförmige und/oder feinkörnige Bestandteile enthaltenden Gemischs aus wenigstens zwei Komponenten gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a stirring tool for producing a liquid, optionally gaseous and / or fine-grained constituents containing mixture of at least two components according to the preamble of claim 1.

Mischen ist eine in der chemischen Technik oft ausgeübte Operation. Fluide Mischungspartner werden üblicherweise in feststehenden Behältern mit rotierenden Mischeinrichtungen, die in der Mitte des Behälters angeordnet sind, durch Zwangsströmungen gemischt. In der Regel wird ein möglichst homogener Verteilungszustand der Mischungspartner angestrebt. In den bekannten Mischapparaturen für Fluide, beispielsweise Rührbehälter mit einem mechanisch bewegten Scheibenrührer, ist die erreichbare Homogenität der Mischung häufig unbefriedigend, insbesondere wenn höherviskose Mischungspartner verarbeitet werden müssen. Das Problem stellt sich auch beim Durchmischen, Dispergieren, Emulgieren, Einrühren von verschiedenen Komponenten, von denen zumindest eine in einem leicht fließfähigen Zustand vorliegt, in kleinen Behältern, wie sie z.B. in einem Labor eingesetzt werden. Ursächlich hierfür ist die den zu mischenden Komponenten nicht in ausreichendem Maße zuführbare Mischenergie, so dass nur eine entsprechend geringe Verdränger- und Scherwirkung in dem Komponentengemisch erreicht werden kann.Mixing is a common practice in chemical engineering. Fluid mixing partners are usually mixed in fixed containers with rotating mixers arranged in the center of the container by forced flows. As a rule, a homogeneous distribution state of the mixing partners is sought. In the known mixing apparatus for fluids, for example stirred tank with a mechanically agitated disk stirrer, the achievable homogeneity of the mixture is often unsatisfactory, especially when higher-viscosity mixing partners have to be processed. The problem also arises when mixing, dispersing, emulsifying, stirring in various components, at least one of which is in a readily flowable state, in small containers, such as e.g. be used in a laboratory. The reason for this is the mixing energy that can not be supplied to a sufficient extent to the components to be mixed, so that only a correspondingly low displacement and shear action in the component mixture can be achieved.

Aus der DE 195 04 033 C2 ist ein motorgetriebener Rührer zum Mischen kleiner Mengen von Flüssigkeiten, Emulsionen, Dispersionen und von Trocken- oder Nassmischungen aus feinkörnigen Feststoffen bekannt, bei dem endseitig an einer Rührwelle eine Rotorscheibe befestigt ist. Die Rotorscheibe besteht aus einer kreisförmigen Flügelscheibe und besitzt Durchströmöffnungen, welche sich radial vom Zentrum der Scheibe bis in die Nähe ihres Außenumfangs erstrecken. An den radialen Seitenkanten der Durchströmöffnungen sind nach oben und nach unten gerichtete Mischflügel angebracht, über die eine gleichförmige Wellenströmung in dem Mischgut erzeugt werden soll. Die mit einer solchen Rührerkonstruktion erzielbare Mischgüte befriedigt jedoch nicht in jeder Hinsicht, da die durch die Mischflügel gebildeten Kanäle nach oben bzw. unten offen sind und sich somit nur bedingt Zwangsströmungen ergeben. Darüber hinaus ist während der Rotation des Rührers ein Mitdrehen des Mischgutes im Behälter praktisch nicht zu vermeiden.From the DE 195 04 033 C2 is a motor-driven stirrer for mixing small amounts of liquids, emulsions, dispersions and dry or wet mixtures of fine-grained solids known in the end to a stirring shaft, a rotor disk is attached. The rotor disk consists of a circular disk disk and has flow-through openings which extend radially from the center of the disk to the vicinity of its outer periphery. At the radial side edges of the flow-through upward and downward directed mixing blades are attached, via which a uniform wave flow is to be generated in the mix. However, the achievable with such a stirrer mixing quality does not satisfy in every way, since the channels formed by the mixing blades are open upwards or downwards and thus result only limited forced flows. In addition, during the rotation of the stirrer co-rotation of the mixed material in the container practically unavoidable.

Es ist daher Aufgabe der Erfindung, ein Rührwerkzeug der im Oberbegriff des Anspruchs 1 angegebenen Art so zu verbessern, dass mit einfachen Mitteln eine stärkere örtliche Durchmischung von wenigstens zwei Komponenten erzielbar ist und dass besonders rasch reproduzierbare Komponentengemische in verbesserter Mischgüte erhalten werden können.It is therefore an object of the invention to improve a stirrer specified in the preamble of claim 1 type so that with simple means a stronger local mixing of at least two components can be achieved and that particularly rapidly reproducible component mixtures can be obtained in improved mixing quality.

Zur Lösung dieser Aufgabe werden die im Kennzeichen des Anspruchs 1 enthaltenen Maßnahmen vorgeschlagen.To solve this problem, the measures contained in the characterizing part of claim 1 are proposed.

Bei dem Rührwerkzeug nach der Erfindung sind in einer endseitig an einer Rührwelle befestigten kreis- oder polygonförmigen Rotorscheibe mehrere, vorzugsweise 4-6 Durchströmkanäle vorgesehen. Diese bestehen aus strömungstechnisch miteinander verbundenen axialen Bohrungen und radialen oder tangentialen Bohrungen. Beim Durchführen des Mischungsvorgangs entsteht infolge der durch die Rotorscheibe erzeugten Fliehkräfte ein Unterdruck in den Durchströmkanälen, der eine zusätzliche vertikale Strömung im Komponentengemisch induziert. Es werden entsprechend der Anzahl der Durchströmkanäle Teilströme aus dem Mischgut angesaugt, in den axialen Bohrungen umgelenkt und aus den radialen oder tangentialen Bohrungen ausgetragen, wobei eine kräftige Turbulenz erzeugt wird. Die sich einstellende Zirkulationsströmung führt zu einem besonders homogenen und stabilen Komponentengemisch.In the agitating tool according to the invention, a plurality of, preferably 4-6, flow-through channels are provided in a circular or polygonal rotor disk attached to one end of a stirring shaft. These consist of aerodynamically interconnected axial bores and radial or tangential bores. When carrying out the mixing process, a negative pressure in the flow-through channels, which induces an additional vertical flow in the component mixture, arises as a result of the centrifugal forces generated by the rotor disk. There are sucked according to the number of flow channels partial streams from the mix, deflected into the axial bores and discharged from the radial or tangential bores, with a strong turbulence is generated. The resulting circulating flow leads to a particularly homogeneous and stable component mixture.

Die erfindungsgemäßen Durchströmkanäle können kreisrunde oder polygonförmige Querschnitte aufweisen und gegebenenfalls konisch ausgebildet sein. Sie sind vorzugsweise symmetrisch zueinander angeordnet, derart, dass auf einem Teilkreis der oberen oder unteren Stirnfläche der Rotorscheibe axiale Bohrungen soweit in die Rotorscheibe eingebracht werden bis sie die radialen oder tangentialen Bohrungen schneiden. Hierdurch lassen sich besonders wirksam Gase oder Feststoffe in einem Komponentengemisch homogen verteilen.The flow channels according to the invention may have circular or polygonal cross-sections and optionally be conical. They are preferably arranged symmetrically to each other, such that on a pitch circle of the upper or lower end face of the rotor disk axial bores are introduced as far into the rotor disk until they intersect the radial or tangential bores. As a result, gases or solids can be distributed homogeneously in a component mixture in a particularly effective manner.

Nach einem weiteren Merkmal der Erfindung sind die axialen Bohrungen Durchgangsbohrungen. Auf diese Weise können bei Anordnung der Rotorscheibe im Bereich der Phasengrenze der zu mischenden Komponenten diese oberhalb und unterhalb der Rotorscheibe angesaugt, in den radialen oder tangentialen Bohrungen zusammengeführt und in turbulenter Strömung ausgetragen werden, wobei kontinuierlich Komponententeilströme nachgesaugt werden. Durch diese Zwangsströmungen ergibt sich eine intensive Durchmischung von Komponenten, insbesondere Komponenten unterschiedlicher Konsistenz innerhalb kurzer Rührzeiten.According to a further feature of the invention, the axial bores are through holes. In this way, when the rotor disk is arranged in the region of the phase boundary of the components to be mixed, they can be sucked in above and below the rotor disk, brought together in the radial or tangential bores and discharged in turbulent flow, wherein component partial streams are continuously sucked in. These forced flows result in an intensive mixing of components, in particular components of different consistency within short stirring times.

Um die beim Mischen flüssiger Komponenten in einem Rührbehälter sich einstellende und das Mischergebnis nachteilig beeinflussende Trombenbildung zu vermeiden, kann in weiterer Ausgestaltung des erfindungsgemäßen Rührwerkzeugs die aus einem Zylinderabschnitt bestehende Rotorscheibe auf wenigstens einer Stirnfläche des Zylinderabschnitts kegel- oder kegelstumpfförmig ausgebildet sein. Bei einer polygonförmigen Rotorscheibe kann auf wenigstens einer Stirnfläche eine entsprechend polyederförmige Erhebung ausgebildet sein. Die axialen Bohrungen erstrecken sich bei diesen Ausführungensformen der Rotorscheibe natürlich auch durch die kegel- oder polyederförmigen Erhebungen.In order to avoid the formation of bubbles during the mixing of liquid components in a stirred vessel and adversely affecting the mixing result, in a further embodiment of the stirring tool according to the invention, the rotor disk consisting of a cylinder section can be designed with a cone or truncated cone on at least one end face of the cylinder section. In a polygonal rotor disk may be formed on at least one end face a corresponding polyhedral elevation. The axial bores extend in these embodiments of the rotor disc, of course, by the conical or polyhedral elevations.

Das Rührwerkzeug nach der Erfindung eignet sich beispielsweise zum Mischen, Emulgieren von Flüssigkeiten, leicht pastösen Formulierungen sowie zum Lösen oder Dispergieren von Feststoffen und/oder Gasen in Flüssigkeiten, insbesondere zum Mischen von chemisch reaktionsfähigen Komponenten wie beispielsweise Lackbindemittel und Härter, Monomerlösungen und Katalysatoren, Polymerlösungen und Wirkstoffe sowie Klebstoff-Formulierungen.The stirring tool according to the invention is suitable for example for mixing, emulsifying liquids, slightly pasty formulations and for dissolving or dispersing solids and / or gases in liquids, in particular for mixing chemically reactive components such as paint binders and hardeners, monomer solutions and catalysts, polymer solutions and active ingredients and adhesive formulations.

Im Wesentlichen besteht das Rührwerkzeug nach den Figuren 1 bis 3 aus einer antreibbaren Rührwelle (1) und einer endseitig an der Rührwelle befestigten Rotorscheibe (2) in Form eines Zylinderabschnitts. Die Rotorscheibe enthält vier symmetrisch angeordnete Durchströmkanäle, die aus vier axialen Bohrungen (3) und vier radialen Bohrungen (4) gebildet sind. Jeweils eine axiale Bohrung ist mit einer radialen Bohrung verbunden. Der radiale Abstand der Bohrungen (3) von der Rührwelle (1) kann in Abhängigkeit der Durchmesser der Rotorscheibe und der Durchströmkanäle variiert werden. Mit (5) sind kegelförmige Erhebungen auf den Stirnflächen des Zylinderabschnitts der Rotorscheibe bezeichnet.In essence, the stirring tool according to FIGS. 1 to 3 consists of a drivable stirrer shaft (1) and a rotor disk (2) fastened to the end of the stirrer shaft in the form of a cylinder section. The rotor disk contains four symmetrically arranged through-flow channels, which are formed from four axial bores (3) and four radial bores (4). In each case an axial bore is connected to a radial bore. The radial distance of the bores (3) from the agitator shaft (1) can be varied depending on the diameter of the rotor disk and the flow-through channels. With (5) conical protrusions are designated on the end faces of the cylinder portion of the rotor disk.

Zur Herstellung eines homogenen Gemischs wird das Rührwerkzeug in die in einem feststehenden Rührbehälter enthaltenden Komponenten eingetaucht und in eine Drehbewegung versetzt. Die hierdurch entstehenden Fliehkräfte bewirken eine Komponentenförderung durch die radialen Bohrungen (4) während durch die axialen Bohrungen (3) kontinuierlich Komponentenströme von oben und unten nachfließen. In den radialen Bohrungen sowie beim Austreten der Komponenten bzw. des Komponentengemischs aus den Durchströmkanälen erfolgt eine Vermischung der Komponenten bzw. des aus den Durchströmkanälen austretenden Komponentenstromes mit dem Rührbehälterinhalt. Durch wiederholtes Fördern des Mischgutes durch die Durchströmkanäle werden besonders homogene Gemische erhalten. Strömungsbeeinflussende Körper in den Durchströmkanälen (in den Zeichnungen nicht dargestellt) können die Mischwirkung erhöhen.To produce a homogeneous mixture, the stirring tool is immersed in the components contained in a stationary stirring container and set in a rotary motion. The resulting centrifugal forces cause a component delivery through the radial bores (4) while the axial bores (3) continuously flow component flows from above and below. In the radial Drilling as well as the leakage of the components or of the component mixture from the flow-through channels, a mixing of the components or the emerging from the flow passages component flow with the Rührbehälterinhalt. By repeatedly conveying the mixed material through the flow channels particularly homogeneous mixtures are obtained. Flow-influencing bodies in the flow-through channels (not shown in the drawings) can increase the mixing effect.

Bei der Ausführungsform des Rührwerkzeuges gemäß der Figuren 4 und 5 reichen die axialen Bohrungen (3) von unten nur soweit in die kreisförmige Rotorscheibe (2) bis sie die mittig in dem Zylinderabschnitt angebrachten Bohrungen (4) schneiden, so dass nur von unten Komponenten oder-gemisch angesaugt wird. Eine solche Konstruktion eignet sich besonders dann, wenn feinkörniger Feststoff in eine Flüssigkeit eingemischt oder wenn der Eintrag von Gasen in die Flüssigkeit vermieden werden soll. Für ein besonders schonendes Mischen von Komponenten hat es sich als zweckmäßig erwiesen, die Bohrungen (4) nicht radial sondern tangential, d.h. unter einem Winkel von etwa 30 bis etwa 45 Grad zur Radialen entgegen der Drehrichtung des Rührwerkzeuges anzuordnen.In the embodiment of the stirring tool according to FIGS. 4 and 5, the axial bores (3) extend from below only into the circular rotor disk (2) until they intersect the bores (4) mounted centrally in the cylinder section, so that only components or components from below Mixture is sucked. Such a construction is particularly suitable when fine-grained solid is mixed into a liquid or when the entry of gases into the liquid should be avoided. For a particularly gentle mixing of components, it has proven to be expedient, the bores (4) not radially but tangentially, i. at an angle of about 30 to about 45 degrees to the radial against the direction of rotation of the agitator to arrange.

Im Allgemeinen ist die Rotorscheibe (2) kreisförmig ausgebildet. Sie kann aber auch aus einem Polygon bestehen, wie dies in den Fig. 6 und 7 gezeigt ist.In general, the rotor disk (2) is circular. But it can also consist of a polygon, as shown in Figs. 6 and 7.
