Patentanspruch:Claim: Vertikalachsiger Oberflächenbelüfter für Abwasser, bei dem ein unten offener, sich drehender Hohlkörper mit mehreren nach außen ansteigenden, kreisförmig angeordneten, geschlossenen Strömungskanälen versehen ist, an deren Außenseite nach unten weisende Schaufeln angebracht sind, dadurch gekennzeichnet, daß der Hohlkörper als oben geschlossener Hohlzylinder (3) ausgebildet ist, in dessen oberem senkrechten Wandteil mehrere kreisrunde Löcher ausgebildet sind, in denen eine entsprechende Anzahl von die geschlossenen Strömungskanäle bildenden Rohren (4) eingesetzt ist.Vertical-axis surface aerator for wastewater with a rotating, open at the bottom Hollow body with several outwardly rising, circularly arranged, closed flow channels is provided with blades pointing downwards on the outside, characterized in that the hollow body is a hollow cylinder (3) closed at the top is formed, in the upper vertical wall part formed a plurality of circular holes are in which a corresponding number of the closed flow channels forming the tubes (4) is inserted. Die Erfindung betrifft einen vertikalachsigen Oberflächenbelüfter für Abwasser, bei dem ein unten offener, sich drehender Hohlkörper mit mehreren nach außen ansteigenden, kreisförmig angeordneten, geschlossenen Strömungskanälen versehen ist, an deren Außenseite nach unten weisende Schaufeln angebracht sind.The invention relates to a vertical-axis surface aerator for waste water, in which a bottom open, rotating hollow body with several outwardly rising, circularly arranged, closed Flow channels is provided, on the outside of which blades pointing downwards are attached. Ein Oberflächenbelüfter dieser Art ist durch die schweizerische Patentschrift 3 68 757 bekannt. Bei dieser bekannten Vorrichtung sind an einem kegelstumpfförmigen sich nach oben erweiternden Teil Schaufeln befestigt, die mit einem weiteren ringförmigen Teil Strömungskanäle bilden. In der schweizerischen Patentschrift 4 15 480 ist ein ähnlicher Belüfter dargestellt.A surface aerator of this type is known from Swiss patent specification 3 68 757. at of this known device are on a frustoconical part which widens upwards Fastened blades, which form flow channels with a further annular part. In the Swiss A similar aerator is shown in U.S. Patent 4,155,480. Diese Vorrichtung hat jedoch den Nachteil, daß durch die Vielzahl der Kanten eine hohe Verstopfungsgefahr besteht, und die Konstruktion dadurch sehr kompliziert ist, daß sie aus einer Anzahl von einzelnen speziell geschnittenen und zusammengefügten Blechen gebildet werden muß.However, this device has the disadvantage that there is a high risk of clogging due to the large number of edges consists, and the construction is very complicated in that it is made up of a number of individual ones specifically cut and joined sheets must be formed. Der Erfindung liegt daher die Aufgabe zugrunde einen Oberflächenbelüfter der eingangs genannten Art zu schaffen, bei dem eine möglichst geringe Verstopfungsgefahr besteht und der zugleich eine einfache Bauweise aufweist.The invention is therefore based on the object of a surface aerator of the type mentioned at the beginning to create with the lowest possible risk of clogging and at the same time a simple one Has construction. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Hohlkörper als oben geschlossener Hohlzylinder ausgebildet ist, in dessen oberem senkrechten Wandteil mehrere kreisrunde Löcher ausgebildet sind, in denen eine entsprechende Anzahl von die geschlossenen Strömungskanäle bildenden Rohren eingesetzt ist.According to the invention, this object is achieved in that the hollow body is a hollow cylinder closed at the top is formed, in the upper vertical wall part of which several circular holes are formed, in which a corresponding number of tubes forming the closed flow channels is inserted. Die mit der Erfindung erzielten Vorteile liegen darin, daß der Oberflächenbelüfter weniger Kanten aufweist und damit die Verstopfungsgefahr vermindert ist und von der Fertigung her sehr einfach herzustellen ist.The advantages achieved with the invention are that the surface aerator has fewer edges and thus the risk of clogging is reduced and is very easy to manufacture in terms of manufacture. Die Erfindung ist in der Zeichnung beispielsweise dargestellt. Der in der Zeichnung dargestellte Oberflächenbelüfter besteht im einzelnen aus einer senkrechten Antriebswelle 1, welche von der nicht dargestellten Antriebseinheit angetrieben wird und über eine Flanschverbindung 2 mit einem unten offenen, oben geschlossenen Hohlzylinder 3 verbunden ist. Die radial angeordneten Strömungskanäle bestehen hier aus Rohren 4, die im oberen senkrechten Wandteil des Hohlzylinders 3 an Rundlöcher angeschlossen sind. An der unteren Seite der Anschlußrohre sind in diesem Fall dreiecksförmige Schaufeln 5 annährend senkrecht befestigt.The invention is shown in the drawing, for example. The surface aerator shown in the drawing consists in detail of a vertical drive shaft 1, which of the not shown Drive unit is driven and via a flange connection 2 with an open below, above closed hollow cylinder 3 is connected. The radially arranged flow channels consist of here Pipes 4, which are connected to round holes in the upper vertical wall part of the hollow cylinder 3. At the lower side of the connecting pipes in this case triangular blades 5 are approximately perpendicular attached.
