Description

"Speisevorrichtung für Schneckenpumpen" Das Hauptpatent (Anmeldung N 23 117 IC/59e) betrifft eine Speisevorrichtung für Schneckenpumpen, bei der einem Rotor, der in einem feststehenden Stator umläuft, mittels einer besonderen Schnecke unplastisches, kleinstÜckiges und feuchtes Fördergut zugeführt wird. Zur Erhöhung der Einzugsleistung-des Rotors ist bei der vorliegenden Erfindung eine besondere Ausbildung des Stators an seinem Einzugsende vorgeschlagen, die darin besteht, daß dieses Ende in Fortsetzung der Gewindegänge konisch erweitert ist. Die Schneckengänge des Rotors lau-fen in dieser Erweiterung aus und wird das in die konische Erweiterung eingesaugte FÖrdergut beim Umlauf des Rotors leichter in die Schneckengänge eingebracht und von ihnen erfaßt. Durch diese Maßnahme wird bei der Förderung von Faserstoffen, Papierstoff, Gerste, Maische und ähnlichen Fördergütern eine Mehrleistung der-Pumpe bis zu 100 % erreicht. In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt. Fig. 1 zeigt einen Schnitt durch das Pumpengehäuse mit dem über das Einzugsende hinausragenden-Rotor; Fig. 2 das erweiterte Einzugsende des Stators im vergrößerten 1,v-.aßstab und Fig. 3 dasselbe in der Vorderansicht. Der Stator 1 ist in eineig Stahlrohr 2 einvulkanisiert, das einen Teil des Pumpengehäuses bildet. Am Einzugsende ist der Stator mit einer konischen Erweiterung 3 versehen, deren Außendurchmesser vorzugsweise dem Außendurchmesser der Gewindegänge 4, 41 entspricht. Der Rotor ist mit 5 bezeichnet."Feed device for screw pumps" The main patent (application N 23 117 IC / 59e) relates to a feed device for screw pumps, in which a rotor, which rotates in a stationary stator, is fed non-plastic, small and moist material to be conveyed by means of a special screw. To increase the pull-in power of the rotor, the present invention proposes a special design of the stator at its pull-in end, which consists in that this end is conically widened in continuation of the thread turns. The worm threads of the rotor run out in this extension and the conveyed material sucked into the conical extension is more easily brought into the worm threads and grasped by them as the rotor rotates. This measure increases the pump output of up to 100% when conveying pulps, paper stock, barley, mash and similar conveyed goods. In the drawing, the subject matter of the invention is shown in an exemplary embodiment. 1 shows a section through the pump housing with the rotor protruding beyond the intake end; FIG. 2 shows the extended retraction end of the stator in an enlarged 1, v-scale, and FIG. 3 shows the same in the front view. The stator 1 is vulcanized into some steel tube 2 which forms part of the pump housing. At the draw-in end, the stator is provided with a conical enlargement 3 , the outer diameter of which preferably corresponds to the outer diameter of the threads 4, 41. The rotor is denoted by 5.
