Description

Pumpe für breiiges oder Stücke enthaltendes Fördergut mit Zubringevorrichtung Es sind Pumpen für breiiges oder Stücke enthaltendes Fördergut mit Zubringevorrichtungen bekannt, bei denen die Schnecken auf derselben Welle angeordnet sind wie die Pumpe, so @daß Schnecken und Pumpe mit der gleichen Geschwindigkeit umlaufen müssen. Hieraus ergibt sich eine Beeinträchtigung der Wirkung der Schnecken oder aber der Pumpe, da für diese ganz verschiedene Geschwindigkeiten zur Erreichung einer guten Leistung erforderlich sind.Pump for conveying material containing pulp or pieces with a feeding device They are pumps for conveying goods with pulpy or pieces containing conveying devices known, in which the screws are arranged on the same shaft as the pump, so @ that the screw and the pump must rotate at the same speed. From this there is an impairment of the action of the screws or the pump, because for this very different speeds to achieve a good performance required are.

Dieser Nachteil wird gemäß der Erfindung dadurch behoben, daß die- der Pumpe vorgeschaltete Zubringevorrichtung gegenüber der Pumpe einen gesonderten Antrieb erhält. Diese Zubringevorrichtung kann gleichzeitig als Zerkleinerungs- oder Mischvorrichtung ausgebildet oder mit einer solchen versehen sein.This disadvantage is eliminated according to the invention in that the- The feed device upstream of the pump has a separate feed device compared to the pump Drive receives. This feeding device can also be used as a shredding or mixing device or be provided with such a device.

Bei dieser Anordnung wird die dem Fördergut durch die Zerkleinerungsvorrichtung erteilte Bewegungsenergie dazu ausgenutzt, selbst steife oder stückige Massen in die Pumpe zu bringen.With this arrangement, the material to be conveyed is passed through the shredding device Granted kinetic energy is used to even stiff or lumpy masses in bring the pump.

Bei Kolbenpumpen, namentlich bei eineiti- wirkenden, die den herbeigedrückten Stoff nur absatzweise aufnehmen, ist es nützlich, einen Windkessel vor die Pumpe zu schalten, der einen Druckausgleich herbeiführt, oder ein feder- oder gewichtsbelastetes Rück- oder Umlaufventil anzuordnen, das den jeweilig überschüssigen Stoff in die Zuleitung zurückführt. Die Zeichnung stellt Ausführungsbeispiele für diese Anordnungen dar.With piston pumps, especially with single-acting pumps that push the one towards you If you only want to pick up material in intermittent steps, it is useful to have an air chamber in front of the pump to switch, which brings about a pressure equalization, or a spring or weight-loaded To arrange return or circulation valve, which the respective excess substance in the Leads back. The drawing represents exemplary embodiments for these arrangements represent.

Ahb. i zeigt eine einfach wirkende Kolbenpumpe a, der eine mit einer Siebscheibe h versehene Preßschnecke c den ihr bei d zufließenden Stoff zutreibt, während ein Umlaufventil c den jeweilig überschüssigen Stoff in den Einlauf zurückleitet.Ahb. i shows a single-acting piston pump a, which a press screw c provided with a sieve disk h drives the substance flowing in at d, while a circulation valve c guides the respective excess substance back into the inlet.

Abb. a zeigt einen zwischen der Preßschnecke c und der Pumpe eingeschalteten Windkessel f.Fig. A shows one connected between the press screw c and the pump Windkessel f.

Abb. 3 zeigt eine der Abb. i entsprechende Anordnung mit einer Kreiselpuinpeg.Fig. 3 shows an arrangement corresponding to Fig. I with a centrifugal guinpeg.
