Abstract
(DE)
Um zu verhindern, daß sich bei einem Rührwerk für feststoff- oder faserhaltige Flüssigkeiten derartige Bestandteile in den Spalt (8) einziehen können, der sich zwischen der Propellernabe (5) und dem Gehäuse (1) für den Antriebsmotor befindet, wird ein elastischer Abweisring (9) vorgeschlagen, der sowohl die Propellernabe (5) wie auch das Gehäuse (1) übergreift und eine tragflächenartige äußere Umfangsfläche (15) aufweist. Dieser Abweisring (9) liegt mit einer Dichtfläche (14) auf der Propellernabe (5), wobei durch die tragflügelartige Ausbildung der äußeren Umfangsfläche (15) eine Strömungsbeschleunigung hervorgerufen wird, die die Feststoffteilchen oder faserhaltige Bestandteile vom Abweisring (9) bzw. Spalt (8) wegreißt.
(EN)
The invention concerns an agitator for fluids which contain solids of fibres and prevents these substances entering the gap (8) between the propeller boss (5) and the drive motor housing (1). To this end, a resilient deflector ring (9) overlaps both the propeller boss (5) and the housing (1) and has an outer peripheral surface (15) acting as a support surface. This deflector ring (9) lies with a sealing surface (14) on the propeller boss (5). The design of the external peripheral surface (15) as a support surface produces flow acceleration such that the solids particles or fibrous components are drawn away from the deflector ring (9) or gap (8).
(FR)
L'invention concerne un agitateur pour fluides renfermant des substances solides ou fibreuses, qui permet d'éviter que ces éléments ne pénètrent dans la fente (8) située entre le moyeu d'hélice (5) et le carter (1) du moteur d'entraînement. A cet effet, un anneau déflecteur élastique (9) repose sur le moyeu d'hélice (5) et le carter (1), et présente une surface périphérique extérieure (15) faisant office de surface d'appui. Cet anneau déflecteur (9) repose avec une surface d'étanchéité (14) sur le moyeu d'hélice (5). La conception sous forme de surface d'appui de la surface périphérique extérieure (15) crée une accélération du flux qui retire et entraîne les particules solides ou les éléments fibreux de l'anneau déflecteur (9) ou de la fente (8).
