Description
Schneckenradpumpe Die vorliegende Erfindung betrifft eine Schnek- kenradpumpe zum Fördern von Flüssigkeiten mit aufgeschwemmten Feststoffen, bei der die Schnecke in den Saugmund bzw. -stutzen vorgezogen ist. Die Pumpe ist nun gemäss der .Erfindung dadurch ge kennzeichnet, dass der radiale Abstand der Umfangs kante der Schnecke zu deren Achse stetig zunimmt und in den Saugmund bzw. -stutzen hinein, einer Spirallinie folgend, an dessen Umfang gelangt; das Ganze derart, dass ein Zerschneiden der Feststoffe verhindert wird, indem diese beim Fördern gegen die Radachse abgelenkt werden.
Ein Ausführungsbeispiel der Erfindung, in An wendung auf eine Fischpumpe, ist in der Zeichnung im Axialschnitt dargestellt in Fig. 1 und im Quer schnitt nach der Linie 11-II der Fig. 1 in Fig.2.
Das Schneckenrad 1 weist einen radialen Teil la von an sich bekannter Bauart auf, nebst dem erfin dungsgemässen schneckenförmigen Schaufelanfang 1b mit seiner gegen die Radachse abfallenden und axial in diese hineinwachsenden (1d) Kante 1c.
Das Rad 1 befindet sich- in einem Spiralgehäuse 2 und wird über die Welle 3 rotiert. Der Schaufel anfang 1b schraubt sich in die von der Saugleitung 4 kommende Flüssigkeit-Feststoff-Masse. Die auf die Schaufelkante 1c fallenden Feststoffe 5 werden un beschädigt gegen die Radachse abgelenkt, wo sie in den Schaufelradkanal 2a und durch das Gehäuse 2 in das Druckrohr 6 gelangen. Beim vorliegenden Bei spiel ist ein offenes Rad 1 gezeigt, dieses kann aber auch geschlossen, d. h. mit Seitenwand ausgebildet sein.
Die stark gegen die Radachse abfallende Schaufel kante 1c vermeidet ein Zerschneiden von mit der Flüssigkeit geförderten Festkörpern. Die direkt auf die Schaufel fallenden Teile werden gegen die Rad achse geleitet, wo die Umfangsgeschwindigkeit relativ klein ist und wo - im Falle von Textil- oder Papier material - faserige Festteile sich nicht an der Schau fel verfangen können, sondern in den Radkanal 2a abgleiten.
Das vorliegende Rad wird mit Vorteil insbe sondere zum Fördern von Fischen, Textil- und Papiermaterialien verwendet. Die wichtigsten Vor teile gegenüber bekannten Rädern, z. B. schaufellose Schlauch- und andere Schlammräder, sind: Das Aus wuchten geschieht rascher und einfacher; ein Zer schneiden und Auffangen von Festmaterial wird vermieden; auch breiige Massen hoher Konzentration können gefördert werden, indem der schnecken förmige Schaufelanfang 1b sich leicht in solche bohrt.
Worm gear pump The present invention relates to a worm gear pump for pumping liquids with suspended solids, in which the worm is pulled forward into the suction mouth or nozzle. According to the invention, the pump is characterized in that the radial distance between the circumferential edge of the screw and its axis increases steadily and, following a spiral line, reaches its circumference into the suction mouth or nozzle; the whole thing in such a way that the solids are prevented from being cut up by deflecting them against the wheel axle during conveyance.
An embodiment of the invention, in application to a fish pump, is shown in the drawing in axial section in Fig. 1 and in cross section along the line 11-II of Fig. 1 in Fig.2.
The worm wheel 1 has a radial part la of a type known per se, in addition to the helical blade beginning 1b according to the invention with its edge 1c sloping towards the wheel axis and axially growing into it (1d).
The wheel 1 is located in a spiral housing 2 and is rotated via the shaft 3. The beginning of the scoop 1b is screwed into the liquid-solid mass coming from the suction line 4. The solids 5 falling onto the blade edge 1c are deflected undamaged against the wheel axle, where they get into the blade wheel channel 2a and through the housing 2 into the pressure pipe 6. In the present case, an open wheel 1 is shown, but this can also be closed, i.e. H. be designed with a side wall.
The blade edge 1c, which slopes sharply towards the wheel axle, avoids cutting up solids conveyed with the liquid. The parts falling directly onto the shovel are directed against the wheel axis, where the peripheral speed is relatively low and where - in the case of textile or paper material - fibrous solid parts cannot get caught on the shovel, but slide into the wheel channel 2a.
The present wheel is used with advantage in particular special for conveying fish, textile and paper materials. The most important before parts compared to known wheels, z. B. vane-less hose and other mud wheels are: Balancing is quicker and easier; cutting and collecting solid material is avoided; Even pulpy masses of high concentration can be conveyed by the screw-shaped blade beginning 1b boring easily into such.
