Abstract
Beschrieben wird ein axial angeströmtes Radial-Lüfterrad zum Fördern eines mit Partikeln beladenen Strömungsmittels. Es hat ein angetriebenes Trägerteil, das sich im Wesentlichen senkrecht zu einer Drehachse erstreckt und eine Schaufelanordnung mit einer Vielzahl von kranzartig im Umfangsabstand zueinander angeordneten Lüfterradschaufeln trägt. Die Lüfterradschaufeln weisen jeweils eine radial innenliegende Anströmkante und eine radial außenliegende Austrittskante auf. Zwischen den Lüfterradschaufeln sind radial nach außen gerichtete Strömungskanäle festgelegt, wodurch eine axiale Eintrittströmung radial nach außen umlenkbar ist. Um mit festen und/oder flüssigen Grobpartikeln beladene Strömungsmittel beim Durchströmen des Lüfterrads wirksam zu reinigen, hat das Trägerteil radial innerhalb der Lüfterradschaufeln zusätzliche vom Trägerteil axial vorstehende Zusatzschaufeln, die in Drehrichtung des Lüfterrads derart angestellt sind, dass in dem zu fördernden Fluid enthaltene Partikel mit einer zum Trägerteil hin gerichteten Kraftkomponente beaufschlagbar sind. Described is an axial impinged radial impeller for conveying a particle laden fluid. It has a driven support member extending substantially perpendicular to an axis of rotation and carrying a vane assembly having a plurality of vane-like circumferentially spaced impeller vanes. The fan blades each have a radially inward leading edge and a radially outer trailing edge. Between the fan blades radially outwardly directed flow channels are defined, whereby an axial inlet flow can be deflected radially outwards. In order to effectively clean fluid laden with solid and / or liquid coarse particles as it flows through the fan, the support member has radially within the Lüfterradschaufeln additional axially projecting auxiliary blades from the support member, which are employed in the direction of rotation of the fan so that in the fluid to be conveyed particles with a force component directed towards the carrier part can be acted upon.
