KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei den bisher gebräuchlichen Kreiselpumpen für Fördergut mit festen Bestandteilen besteht der Übelstand, daß sich lange biegsame Körper, z. B. Strohhalme, an der Innenseite der Flügel aufwickeln bzw. sich um sie legen, bis der ganze Durchgang zwischen den einzelnen Flügeln vollständig verstopft ist, so daß keine Flüssigkeit mehr die Flügel durchströmen kann bzw. die Pumpe nicht mehrIn the previously used centrifugal pumps for conveyed goods with solid components there is the disadvantage that long flexible bodies such. B. Straws, on the inside the wings wind up or wrap themselves around them until the entire passage between them The wings are completely clogged so that no more liquid can flow through the wings can or the pump no longer
ίο fördert. Durch die vorliegende Erfindung soll dieser Übelstand beseitigt werden, indem mindestens ein an der Eintrittskante der Laufradflügel anliegender Teil vorgesehen ist, welcher derart ausgebildet und angeordnet ist, daß er biegsame Körper, wie Strohhalme o. dgl., verhindert, sich an den Eintrittskanten der Laufradflügel festzusetzen.ίο promotes. The present invention is intended to This drawback can be eliminated by adding at least one to the leading edge of the impeller blades adjoining part is provided which is designed and arranged in such a way that it has flexible bodies, such as straws o. The like., Prevents getting stuck on the leading edges of the impeller blades.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes im Vertikalschnitt dargestellt.The drawing shows an exemplary embodiment of the subject matter of the invention in vertical section shown.
Mit G ist das Gehäuse der dargestellten Kreiselpumpe, mit S ein an dieses angeschlossener Saugstutzen und mit W die z. B. von einem nicht dargestellten Vorgelege aus angetriebene Welle eines im Innern des Gehäuses G fest auf ihr sitzenden Laufrades L bezeichnet. Das letztere besteht aus einer Scheibe mit an ihrem Rande von der Planseite senkrecht abstehenden Flügeln F, deren innere Kanten die Eintrittsstelle in das Laufrad für die von letzterem durch den Stutzen S angesaugte Flüssigkeit, z. B. Jauche, bilden.With G the housing of the centrifugal pump shown, with S a suction port connected to this and with W the z. B. by a not shown countershaft driven shaft of a fixedly seated impeller L in the interior of the housing G on her. The latter consists of a disc with blades F protruding vertically at its edge from the flat side, the inner edges of which form the entry point into the impeller for the liquid sucked in by the latter through the nozzle S, e.g. B. manure, form.
Damit · sich in letzterer enthaltene biegsame Körper, z. B. Strohhalme, nicht um die inneren Kanten der Flügel F legen und den Durchgang von Jauche zwischen ihnen nicht verhindern können, ist in dem planförmigen Teil des Saugstutzens 5 innerhalb der achsialen Innenkanten der' Laufradflügel ein Zahn ζ eingesetzt. Dieser hat vierkantigen Querschnitt und ist so dicht an den genannten Kanten der Laufradflügel angeordnet, daß um diese sich legende Strohhalme beim Vorbeistreichen , an dem Zahne von ihm durchschnitten und abgestreift werden, wodurch die Eintrittsstelle des Laufrades stets frei bleibt und die Jauche ungehindert zwischen den Flügeln hindurchgelangen kann.So that flexible bodies contained in the latter, e.g. B. straws, do not put around the inner edges of the wings F and the passage of liquid manure between them can not prevent a tooth ζ is inserted in the planar part of the suction nozzle 5 within the axial inner edges of the 'impeller blades. This has a square cross-section and is arranged so close to the mentioned edges of the impeller blades that straws lying around them are cut through and stripped off the teeth when passing them, whereby the entry point of the impeller remains free and the liquid manure unhindered between the blades can get through.
