Description

Zuteilschnecks Es ist bakannt, @uteilschnecken z.B. für staubförmige Güter am Ende des Austrags mit gut abdichtenden Stopfbüchsen zu versehen. Dennoch läßt es sich nicht vermeiden, daß insbesonders My-Fraktionen in die Stopfbüchse eindringen und dort Undichtigkeiten bewirken. Um diesen Nachteil zu beseitigen, wird erfindungsgemäß vorgeschlagen, eine Zuteilschnecke entsprechend beiliegender Zeichnung zu verwenden.Feeding screw It is not known @uteilschnecks e.g. for powdery Provide goods with well-sealed stuffing boxes at the end of the discharge. Yet it cannot be avoided that My fractions in particular get into the stuffing box penetrate and cause leaks there. To eliminate this disadvantage, is proposed according to the invention, a metering screw correspondingly enclosed Drawing to use.

En der Zeichnung, ist dargestellt: mit 1) Materialaufgabe mit 2) Förderschnecke mit Schneckenwindung in Förderrichtung 3) mit 4) der Stopfbüchse vorgelagerte, gegenläufige Schneckenwindung Durch diese Art der vor der Stopfbüchse gelagerten gegenläufigen Schneckenwindung wird die Stopfbüchse entlastet und das Material, das von den Förderschneckenwindungen 2) normalerweise gegen die Stopfbüchse gedrückt würde, in Förderrichtung 3) abgelenkt.In the drawing, it is shown: with 1) material feed with 2) screw conveyor with screw winding in the conveying direction 3) with 4) upstream of the stuffing box, counter-rotating Spiral winding Due to this type of counter-rotating in front of the stuffing box The screw conveyor relieves the stuffing box and the material from the conveyor screw windings 2) would normally be pressed against the stuffing box, deflected in the conveying direction 3).

Selbstverständlich ist die erfindung nicht auf die vorstehend im einzelnen beschriebenen und dargestellten Ausführungen beschränkt, sondern es sind zahlreiche Abänderungen -möglich, ohne jedoch von dem Grundgedanken abzuweichen, eine Zuteilschnecke so zu bauen, daß im Bereich des Auslaufs vor der Stopfbüchse eine gegenläufige Schneckenwindung angebracht ist.Of course, the invention is not limited to the above in detail described and illustrated embodiments are limited, but there are numerous Modifications - possible, but without deviating from the basic idea, a feed screw to be built in such a way that in the area of the outlet in front of the stuffing box there is a counter-rotating spiral is appropriate.
