Description
In pneumatischen Förderrohrleitungen angeordnetes, einseitig offenes Schaufelrad Bei der Förderung staubhaltiger, gasförmiger Stoffe oder bei der pneumatischen Förderung von treide, Malz, Zuckerrübenschnitzel, Häcksel, Holzspänen, Baumwolle u. a. ist man bestrebt, die Reibung des Fördergutes an den Wandungen der Fördereinrichtung möglichst gering zu halten. Diese Reibung ist besonders groß, wenn das Fördergut durch die Laufschaufeln eines Axial- oder Radialventilators hindurchgeführt wird. Sie wird geringer, wenn verdichtete Luft bzw. Gas injektorartig zum Ansaugen und Weitertragen des Fördermediums benutzt wird. Open on one side and arranged in pneumatic conveying pipelines Bucket wheel For conveying dusty, gaseous substances or for pneumatic Transport of grain, malt, sugar beet pulp, chaff, wood shavings, cotton i.a. one strives to reduce the friction of the conveyed material on the walls of the conveyor to be kept as low as possible. This friction is particularly great when the conveyed material is passed through the blades of an axial or radial fan. It is less when compressed air or gas is sucked in and injected like a injector Forwarding of the pumped medium is used.
Der Nachteil der Injektorförderung ist, daß das zum Betrieb erforderliche Arbeitsmedium in einem besonderen Verdichter erzeugt und zur Gebrauchsstelle weitergeleitet werden muß, der Nachteil der Schaufelradventilatoren, daß das Fördergut zwangläufig durch die Schaufelkanäle hindurchgeführt werden muß.The disadvantage of injector funding is that it is necessary for operation Working medium generated in a special compressor and forwarded to the point of use must be, the disadvantage of the impeller fans that the material to be conveyed inevitably must be passed through the blade channels.
Die Erfindung vermeidet diese Mängel unter Verwendung eines in einem Gehäuse umlaufenden, einseitig offenen Schaufelrades dadurch, daß das Schaufelrad aus einer muldenförmigen Scheibe besteht und in eine Vertiefung des Gehäuses derart eingefügt ist, daß der zwischen der offenen Seite des Schaufelrades und der gegenüberliegenden Gehäusewandung verbleibende freie Durchgangsquerschnitt eine Förderung des Gutes lediglich durch die von dem Schaufelrad hervorgerufene Rotation eines Teiles des Fördergutes gestattet. The invention avoids these shortcomings using one in one Housing revolving, one-sided open paddle wheel in that the paddle wheel consists of a trough-shaped disc and in a recess of the housing in such a way is inserted that between the open side of the impeller and the opposite Housing wall remaining free passage cross-section a promotion of the goods caused only by the rotation of part of the paddle wheel Conveyed goods permitted.
Die Zeichnung zeigt schematisch ein Ausführungsbeispiel. The drawing shows schematically an embodiment.
Das angetriebene Schaufelrad 1 besteht aus einer einseitig offenen, muldenförmigen Scheibe, die in eine Vertiefung des Gehäuses eingefügt ist, derart, daß das Schaufelrad selbst nicht im Förderstrom des Gutes liegt. Zwischen der offenen Seite des Schaufelrades und der gegenüberliegenden Wandung des Gehäuses 2 befindet sich ein so großer freier Durchgangsquerschnitt3, daß ein von dem Schaufelrad in Rota tion versetzter geringer Teil des Fördermediums einen Wirbel erzeugt, in den zwangläufig weitere Teile des Fördermediums gezogen werden, ohne daß diese Teile des Fördermediums in das Schaufelrad selbst gelangen. Es wird also der weitaus überwiegende Teil des von dem Fördermedium getragenen Fördergutes ebenfalls nicht mit dem Schaufelrad in Berührung kommen, sondern sofort in der Pfeilrichtung ausgestoßen. Die Weiterleitung des Förderstromes erfolgt dann ähnlich wie bei normalen Zentnfugalventilatoren in einem Spiralgehäuse. The driven paddle wheel 1 consists of a one-sided open, trough-shaped disc, which is inserted into a recess in the housing, in such a way, that the paddle wheel itself is not in the flow of the goods. Between the open Side of the impeller and the opposite wall of the housing 2 is located there is such a large free passage cross-section3 that one of the paddlewheels in Rotation offset small part of the pumping medium creates a vortex in the inevitably further parts of the pumped medium are drawn without these parts of the pumped medium get into the impeller itself. So it will be the overwhelming majority Part of the conveyed goods carried by the conveying medium also not with the paddle wheel come into contact, but immediately ejected in the direction of the arrow. The forwarding of the flow rate is then similar to that of normal central fans in a volute casing.
Die Schaufeln 1' sind in der muldenförmig ausgebuchteten Radscheibe versenkt; der äußere Flügelkreis und der innere Radfiügelkreis liegen in verschiedenen Ebenen. The blades 1 'are in the trough-shaped bulged wheel disk sunk; the outer wing circle and the inner wheel wing circle are in different Levels.
