Description

Die Erfindung betrifft ein Rührwerk entsprechend dem Oberbegriff des Anspruches 1.The invention relates to an agitator according to the preamble of claim 1.

Die bisher verwendeten Rührwerke sind überwiegend mit radialgedichteten oder magnetgekoppelten Behälterdurchführungen für die Rührerwellen ausgerüstet. Schleifende Dichtungen unterliegen hohen Beanspruchungen und hohem Verschleiß, der durch zusätzlichen Einsatz von Schmier- und Kühlvorrichtungen gemindert wird. Dadurch erhöht sich die Gefahr, daß das zu rührende Medium nicht nur durch Abrieb der Dichtung, sondern zusätzlich bei Undichtigkeiten durch Kühl- und Schmiermittel verunreinigt wird. Bei Einsatz magnetgekoppelter Rührwerke ist die Übertragung hoher Drehmomente begrenzt.The agitators used so far are mainly with radially sealed or magnetically coupled tank bushings for the stirrer shafts. Grinding seals are subject to high loads and wear is reduced by the additional use of lubrication and cooling devices. Thereby increases the risk that the medium to be stirred is not only caused by abrasion of the seal, but is additionally contaminated by coolants and lubricants in the event of leaks. When using magnetically coupled agitators, the transmission of high torques is limited.

Aus DE-OS 15 57 130 ist ein Rührwerk mit abgewinkelter Rührwelle bekannt. Durch Kardangelenk und Unwuchtantrieb ist der Aufbau konstruktiv aufwendig.DE-OS 15 57 130 is an agitator with angled Stirring shaft known. Through universal joint and The unbalance drive is structurally complex.

Der Erfindung liegt die Aufgabe zugrunde, ein Rührwerk der im Oberbegriff 1 vorausgesetzten Art zu entwickeln, welches ohne die aufgeführten Nachteile arbeitet. Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.The invention is based, an agitator in the preamble 1 to develop the required type, which works without the disadvantages listed. This object is achieved by the characterizing features of Claim 1 solved.

Bei der erfindungsmäßigen Rührvorrichtung wird eine drehende abgeknickte Rührwelle, die von einem Rührrohr, welches weiter über ein flexibles Dichtungselement mit dem Behältergehäuse verbunden ist, gas- und flüssigkeitsdicht umschlossen. Durch diesen Aufbau ist eine Verunreinigung durch Abrieb, Schmieröle oder Kühlflüssigkeit ausgeschlossen und die Übertragung hoher Drehmomente möglich.In the inventive stirring device, a rotating bent agitator shaft of a stirring tube, which is further connected to the. via a flexible sealing element Container housing is connected, sealed gas and liquid tight. Through this Construction is contamination by abrasion, lubricating oils or coolant excluded and the transmission of high torques possible.

Zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche und werden im Zusammenhang mit der Beschreibung der in den Zeichnungen veranschaulichten Ausführungsbeispiele erläutert.Appropriate embodiments of the invention are the subject of the dependent claims and are illustrated in connection with the description of those illustrated in the drawings Exemplary embodiments explained.
