The long-fiber or strand-like premd materials such fluids must not get tangled and cause blockages in or behind the pump.
TJm dies bei einer Exzenterschneckenpumpe der eingangs genannten Art besonders wirksam-zu verhindern und dabei eine Verengung des DurchgangquerSchnitts und eine Hemmung der Förderung mit dem Schneidwerk möglichst zu vermeiden, besteht neuerungsgemäß das Schneidwerk aus einem mit dem Pumpengehäuse fest verbundenen Schneidring, dessen öffnung eine gezackte oder gewellte Schneidkante aufweist,,und einem damit zusammenwirkenden, sowohl die Drehbewegung als auch die oszillierende Bewegung des Schneckenrotors mitmachenden Schneidrad mit einer spiraligen, als Messerschneide ausgebildeten Speiche. Es kann von Vorteil sein, in Verbindung hiermit eine Federeinrichtung so anzuordnen, daß das Schneidrad und der Schneidring ständig unter elastischem axialen Druck aneinander liegen.TJm to prevent this particularly effectively in an eccentric screw pump of the type mentioned at the outset, and at the same time a Narrowing of the passage cross-section and an inhibition of the conveyance To avoid with the cutting unit as far as possible, according to the innovation the cutting unit consists of one with the pump housing firmly connected cutting ring, the opening of which has a serrated or corrugated cutting edge, and one with it cooperating, participating in both the rotary movement and the oscillating movement of the screw rotor Cutting wheel with a spiral spoke designed as a knife edge. It can be beneficial in conjunction hereby to arrange a spring device so that the cutting wheel and the cutting ring are constantly under elastic axial pressure lie against each other.
Der Vorteil der Neuerung besteht darin, daß der Durchgangsquerschnitt zwischen Schneidring und Schneidrad an der Einlaufstelle zwischen Rotor und Stator verhältnismäßig groß sein kann und die spiralige Messerspeiche diesen Querschnitt nur sehr wenig mindert, während zugleich durch die oszillierende Bewegung und die Drehbewegung des Schneidrades in Verbindung mit der Gestaltung1beider Schneidwerkelemente eine besonders wirksame zwangsläufige - Zerkleinerung der im Fördermedium enthaltenen. Fremdstoffe erreicht wird.The advantage of the innovation is that the passage cross-section between the cutting ring and the cutting wheel at the entry point between the rotor and stator can be relatively large and the spiral knife spoke only slightly reduces this cross-section, while at the same time due to the oscillating movement and the rotary movement of the cutting wheel in connection with the design 1 of both cutter elements a particularly effective inevitable - comminution of the contained in the conveying medium. Foreign matter is reached.
Im folgenden ist die Neuerung anhand der Zeichnung beispielsweise näher erläutert:The following is an example of the innovation based on the drawing explained in more detail:
Pig. 1 und 2 zeigen ein Äusführungsbeispiel einer Exzenterschneckenpumpe gemäß der Neuerung in zwei Schnitt ansichten.Pig. 1 and 2 show an exemplary embodiment of an eccentric screw pump according to the innovation in two sectional views.
1 ist das Pumpengehäuse mit dem Saugstutzen 2 und dem Druckstutzen 3· 4 ist der Stator und 5 der Rotor der Exzenterschneckenpumpe. Das Schneidwerk in dem Vorraum auf der Saugseite besteht aus dem Schneidring 6 und dem Schneidrad 7· Eine Federeinrichtung, welche die beiden Schneidwerkselemente elastisch gegeneinander drückt, ist nicht mit dargestellt. Sie könnte in an sich bekannter Weise durch einen Stapel federnder Ringscheiben gebildet sein, der zwischen die Nabe des Schneidrades 7 und den Körper des Rotors 5, auf dem das Schneidrad tragenden Zapfen 8 des Rotors angeordnet wird. Pig. I läßt die gezackte Schneidkante des Schneidringes 6 sowie ihr Zusammenwirken mit dem Schneidring 7 besonders deutlich erkennen, ebenso wie den verhältnismäßig großen, durch die Bauelemente des Schneidwerks kaum verminderten Durchtrittsquerschnitt. ■1 is the pump housing with the suction nozzle 2 and the pressure nozzle 3 · 4 is the stator and 5 is the rotor of the eccentric screw pump. The cutting unit in the anteroom on the suction side consists of the cutting ring 6 and the cutting wheel 7. A spring device which presses the two cutting unit elements elastically against one another is not shown. It could be formed in a manner known per se by a stack of resilient annular disks, which is arranged between the hub of the cutting wheel 7 and the body of the rotor 5 on which the cutting wheel-bearing pin 8 of the rotor is arranged. Pig. I shows the serrated cutting edge of the cutting ring 6 and its interaction with the cutting ring 7 particularly clearly, as well as the relatively large passage cross-section, which is hardly reduced by the components of the cutting mechanism. ■
