Description

Zentrifugalpumpe zum Fördern von faseriges Gut enthaltenden Flüssigkeiten Die Erfindung behandelt eine Zentrifugalpumpe zum Fördern von faseriges Gut enthaltenden Flüssigkeiten mit Schneiden in Laufrichtung der Pumpe im Raum zwischen den Schaufeln und in Wirkungsverbindung mit scharfkantigen Durchbrechungen der Bodenplatte.Centrifugal pump for pumping liquids containing fibrous material The invention deals with a centrifugal pump for conveying fibrous material containing Liquids with cutting edges in the direction of rotation of the pump in the space between the blades and in connection with sharp-edged openings in the base plate.

Bei einer bekannten Zentrifugalpumpe dieser Art ist das Laufrad saugseitig mit einer Platte abgeschlossen, in der kreisförmige <Öffnungen vorgesehen sind, die mit den Durchbrechungen der Bodenplatte zum Zerschneiden des faserigen Gutes zusammenwirken.In a known centrifugal pump of this type, the impeller is on the suction side closed with a plate in which circular <openings are provided, those with the openings in the base plate for cutting up the fibrous material cooperate.

Diese Öffnungen im Laufrad und in der Bodenplatte geben nur einen begrenzten Teil des Strömungsquerschnitts frei, so daß die Pumpe zum Verstopfen neigt.These openings in the impeller and in the base plate give only one limited part of the flow cross-section free, so that the pump for clogging tends.

Um diesen Nachteil zu vermeiden, wird erfindungsgemäß vorgeschlagen, daß die im Abstand von der Pumpenachse angeordneten Ansaugöffnungen nierenförmige Gestalt haben und die Schneiden durch der Bodenplatte zugewandte, abgewinkelte Kanten der Schaufelblätter gebildet sind.In order to avoid this disadvantage, it is proposed according to the invention that that the suction openings arranged at a distance from the pump axis are kidney-shaped Have shape and the cutting edge through the bottom plate facing, angled edges of the airfoils are formed.

Bei Gebläserotoren ist es bekannt, die Schaufelkanten der Schaufelräder als Schneiden für langfaseriges Gut auszubilden und sie hierzu in Laufrichtung umzubiegen und zuzuschärfen. Eine Scherwirkung im Zusammenwirken mit einer mit Durchbrechungen versehenen Bodenplatte ist hier nicht beabsichtigt.In the case of fan rotors, it is known to use the blade edges of the blade wheels to be designed as cutting edges for long-fiber goods and to bend them in the running direction for this purpose and sharpen. A shear action in conjunction with one with perforations provided base plate is not intended here.
