Description
Die Erfindung bezieht sich auf ein RĆ¼hrwerk mit einer in einem BehƤlter drehbaren RĆ¼hrwerkwelle, an der RĆ¼hrorgane angeordnet sind, und mit einer auĆerhalb des BehƤlters befindlichen Antriebseinheit fĆ¼r die RĆ¼hrwerkwelle. Solche RĆ¼hrwerke sind z.B. aus
An RĆ¼hrwerke, die in sterilen und hochsterilen Anwendungsbereichen, z.B. in der pharmazeutischen Industrie, eingesetzt werden, werden hohe Anforderungen, insbesondere hinsichtlich sicher zu gewƤhrender SterilitƤt gestellt. Sie mĆ¼ssen einerseits leicht zu reinigen und dabei steril zu machen sein, andererseits sollen Ablagerungen, Mƶglichkeiten der Verschmutzung, der Keimbildung usw. von vornherein weitgehendst vermieden werden.Stirrers used in sterile and highly sterile applications, e.g. in the pharmaceutical industry, high demands are made, in particular with regard to certain sterility. On the one hand, they have to be easy to clean and to be sterile, on the other hand, deposits, possibilities of contamination, nucleation, etc., should be largely avoided from the outset.
Bei bekannten RĆ¼hrwerken ist die aus dem BehƤlter herausgefĆ¼hrte RĆ¼hrwerkwelle mit der Antriebswelle einer separat bauenden Antriebseinheit verbunden, die aus dem eigentlichen Antriebsmotor und einem Getriebe besteht, welches die Drehzahl des Antriebsmotors auf die fĆ¼r das RĆ¼hrwerk erforderliche Drehzahl herabsetzt. Verbindungsstellen zwischen Baueinheiten sind immer anfƤllig fĆ¼r Schmutzablagerungen und Verunreinigungen, sie sind meist schwer zugƤnglich und damit schlecht zu reinigen und erst recht nur schwer steril zu halten. Eine Quelle fĆ¼r Verschmutzungen bildet z.B. auch das fĆ¼r ein Getriebe erforderliche Getriebeƶl; die KĆ¼hlrippen eines Motors sind anfƤllig fĆ¼r Ablagerungen.In known agitators, the agitator shaft led out of the container is connected to the drive shaft of a separately constructed drive unit, which consists of the actual drive motor and a gear which reduces the speed of the drive motor to the speed required for the agitator. Junctions between units are always vulnerable to dirt and impurities, they are usually difficult to access and thus difficult to clean and even more difficult to keep sterile. A source of contamination forms e.g. also the transmission oil required for a transmission; The cooling fins of an engine are prone to sedimentation.
Aufgabe der Erfindung ist es, ein RĆ¼hrwerk derart mit einer Antriebseinheit zu versehen und zu verbinden, dass Stellen, die fĆ¼r Ablagerungen und Verunreinigungen und, soweit wie mƶglich, auch deren Quellen vermieden werden und das RĆ¼hrwerk insgesamt, also einschlieĆlich seiner Antriebseinheit, hohen Erfordernissen an SterilitƤt, wie sie beispielsweise, aber nicht nur in der pharmazeutischen Industrie gestellt werden, gerecht wird, dabei notwendige Wartungs- und Reinigungsarbeiten zur Herstellung der SterilitƤt leichter ausfĆ¼hrbar und weniger hƤufig vorzunehmen sind. Die Antriebseinheit soll verkleinert und steriltechnisch optimiert werden.The object of the invention is to provide such an agitator with a drive unit and connect, that places that are avoided for deposits and impurities and, where possible, their sources and the agitator as a whole, including its drive unit, high requirements Sterility, as they are, for example, but not only made in the pharmaceutical industry, meet the necessary maintenance and cleaning work to make the sterility easier to carry out and less frequent. The drive unit is to be scaled down and optimized for sterilization.

Bei einem RĆ¼hrwerk der eingangs genannten Art ist die RĆ¼hrwerkwelle aus dem RĆ¼hrwerkbehƤlter herausgefĆ¼hrt; dabei ist die Antriebseinheit auf dem aus dem RĆ¼hrwerkbehƤlter herausragenden Teil der RĆ¼hrwerkwelle montiert und mit der von der RĆ¼hrwerkwelle durchstoĆenen BehƤlterwand fest verbunden; zugleich sind die Lager der RĆ¼hrwerkwelle und die Abdichtung des Innenraums des RĆ¼hrwerkbehƤlters im Bereich der DurchfĆ¼hrung der RĆ¼hrwerkwelle durch die BehƤlterwand in die Antriebseinheit integriert. Die RĆ¼hrwerkwelle ist also zugleich auch Antriebswelle der Antriebseinheit und kann z.B. auch einstĆ¼ckig mit ihr ausgebildet sein. Dadurch und durch die Verbindung der Antriebseinheit mit der BehƤlterwand wird ein kompakter, Platz sparender Aufbau erreicht; der insgesamt leicht steril zu halten ist.In an agitator of the type mentioned, the agitator shaft is led out of the agitator tank; In this case, the drive unit is mounted on the protruding from the agitator tank part of the agitator shaft and fixedly connected to the pierced by the agitator shaft container wall; At the same time, the bearings of the agitator shaft and the seal of the interior of the agitator vessel in the region of the implementation of the agitator shaft are integrated through the container wall in the drive unit.

Das RĆ¼hrwerk weist vorzugsweise gasdichte StromzufĆ¼hrungen zum Antriebsmotor auf.The agitator preferably has gas-tight power supply lines to the drive motor.
Nach einer anderen AusfĆ¼hrungsform ist ein erstes Lager der RĆ¼hrwerkwelle unmittelbar unterhalb des Antriebsmotors und ein zweites Lager ist im optimierten Abstand zum ersten Lager ebenfalls unterhalb des Antriebsmotors angeordnet, und ein Spalttopf ist zwischen Rotor und Stator angeordnet, durch den der RĆ¼hrwerkbehƤlter hermetisch abgeschlossen ist.According to another embodiment, a first bearing of the agitator shaft is directly below the drive motor and a second bearing is also arranged below the drive motor at the optimized distance from the first bearing, and a split pot is arranged between the rotor and stator, through which the agitator container is hermetically sealed.
Der Spalttopf kann aus einem faserverstƤrkten Kunststoff oder aus hochlegiertem Edelstahl bestehen.The containment shell may consist of a fiber-reinforced plastic or high-alloyed stainless steel.
Bevorzugt ist der Antriebsmotor ein Torquemotor; dabei kann dessen die Permanentmagnete tragender Rotor Ć¼ber eine Buchse durch eine Schrumpfscheibe oder einen Klemmring mit dem aus dem RĆ¼hrwerkbehƤlter herausragenden Teil der RĆ¼hrwerkwelle fest verbunden sein und sein die Wicklungen tragender Stator kann zwischen den Lagerflanschen gehalten sein. Ein Torquemotor ist ein getriebeloser Direktantrieb mit hohen Drehmomenten und relativ kleinen Drehzahlen und eignet sich in idealer Weise fĆ¼r prƤzise Direktantriebe, seine Drehzahl lƤsst sich vorteilhaft auf eine erwĆ¼nschte oder geforderte Drehzahl problemlos abregeln. Da kein Getriebe vorhanden ist, wird auch kein Getriebeƶl benƶtigt und so eine Quelle der Verschmutzung ausgeschlossen. Auch kommt er einer kleinen, Platz sparenden Bauweise entgegen.Preferably, the drive motor is a torque motor; while the rotor carrying the permanent magnets can be fixedly connected to the part of the agitator shaft protruding from the agitator vessel via a bush by a shrink disk or a clamping ring, and its stator carrying the windings can be held between the bearing flanges. A torque motor is a gearless direct drive with high torque and relatively low speeds and is ideally suited for precise direct drives, its speed can be easily adjusted to a desired or required speed easily. Since there is no gear, no gear oil is needed and so excluded a source of pollution. He also meets a small, space-saving design.

Zur Montage kann eine die aus dem RĆ¼hrwerkbehƤlter herausgefĆ¼hrte RĆ¼hrwerkwelle umgebende, ringfƶrmige Adapterplatte vorzugsweise durch Verschraubungen fest mit dem BehƤlter verbunden sein. Der obere Lagerflansch, das GehƤuse des Antriebsmotors und der untere Lagerflansch kƶnnen mittels durch sie hindurchgehender Schrauben mit der Adapterplatte fest verbunden sein. Wenn die AuĆenflƤchen der Lagerflansche, des GehƤuses und der Adapterplatte miteinander fluchten, kann eine geschlossene, nur durch Dichtringe unterbrochene AuĆenflƤche gebildet werden, mit der sich SterilitƤt leicht herstellen lƤsst.For mounting, an annular adapter plate surrounding the agitator shaft leading out of the agitator vessel can be fixedly connected to the container, preferably by screwing. The upper bearing flange, the housing of the drive motor and the lower bearing flange can be firmly connected by means of screws passing through them with the adapter plate. If the outer surfaces of the bearing flanges, the housing and the adapter plate are aligned with each other, a closed, interrupted only by sealing rings outer surface can be formed, with which sterility can be easily produced.

Thus, the sealing of the interior of the agitator tank is integrated into the drive unit.
Die Antriebseinheit kann nach oben durch einen Deckel dicht abgeschlossen sein, und mit diesem Deckel kann eine ZufĆ¼hrungseinheit verbunden sein, die so mit der Antriebseinheit eine Baueinheit bildet und Zuleitungen fĆ¼r gasfƶrmige und/oder flĆ¼ssige Medien aufweist. So wird die ZufĆ¼hrungseinheit in den kompakten, Platz sparenden Gesamtaufbau mit eingeschlossen. Die ZufĆ¼hrungseinheit kann eine DrehdurchfĆ¼hrung sein.The drive unit can be sealed upwards by a cover, and with this cover, a supply unit can be connected, which thus forms a structural unit with the drive unit and has supply lines for gaseous and / or liquid media. Thus, the feeder unit is included in the compact, space-saving overall construction. The feed unit can be a rotary feedthrough.
