Description

Es ist bekannt, geschmolzene Stoffe, insbesondere Metalle, in der Weise in körnige Form überzuführen, elaß man einen Strahl des geschmolzenen Stoffes unter Zuführung von Wasser auf ein sich drehendes Holzrad leitet. Zur besseren Verteilung der geschmolzenen Masse ist es dabei zweckmäßig, das Holzrad mit eingefrästen Nuten zu versehen. Dabei zeigt sich jedoch, daß das Holzrad einem verhältnismäßig starken Verschleiß unterworfen ist und daß die mit zunehmendem Verschleiß immer stärker auftretenden Explosionen eine weitere, so starke Beschädigung des Rades bewirken, daß dieses ausgewechselt werden muß.It is known to have molten substances, especially metals, in the In the manner of granular form, a stream of the molten substance was passed with the supply of water on a rotating wooden wheel. For better distribution the molten mass, it is useful to the wooden wheel with milled grooves to provide. It turns out, however, that the wooden wheel is a relatively strong one Is subject to wear and tear and that with increasing wear, the stronger occurring explosions cause further, so severe damage to the wheel, that this must be replaced.

Es wurde nun gefunden, daß man beim Körnen geschmolzener Stoffe diese Schwierigkeiten bedeutend verringern kann, wenn man die geschmolzene Masse unter Zuführung einer Flüssigkeit auf ein Rad oder eine Walze leitet, auf denen ein in Segmente unterteilter Zahnkranz befestigt ist. Sind einzelne Zähne durch Verschleiß unbrauchbar geworden, so kann man in einfacher Weise, ohne das Rad auszubauen, das betreffende Zahnsegment auswechseln. Ein Segment kann einen oder mehrere Zähne enthalten.It has now been found that when granulating molten substances this Difficulties can be significantly reduced if you take the molten mass under it Feeding a liquid onto a wheel or roller on which an in Segments divided ring gear is attached. Are individual teeth due to wear and tear has become unusable, so you can easily, without removing the wheel, the Replace the relevant tooth segment. A segment can contain one or more teeth.

Die Vorrichtung kann z. B. aus einer Blechwalze i bestehen, die an beiden Enden durch zwei volle Scheiben begrenzt ist, durch die die Antriebswelle geht. Auf der Walze sind in bestimmten Abstän-den scliwall>enschwarrzf@irrnige Federn 2 befestigt, auf die die mit Nuten versehenen Zahnsegmente 3 geschoben sind. Die Zahnsegmente können auch in der Länge der Walze noch unterteilt sein.The device can e.g. B. consist of a sheet metal roll i, which is limited at both ends by two full disks through which the drive shaft goes. Fastened to the roller at certain intervals are narrow, fisted tongues 2, onto which the toothed segments 3, which are provided with grooves, are pushed. The tooth segments can also be subdivided along the length of the roller.

Als Werkstoff für die Zahnsegmente kommt z. B. Preßholz oder Gießholz in Frage. -Man kann auch Naturholz verwenden und dann die Faserrichtung so wählen, <iaß die höchste Widerstandsfähigkeit erreicht wird.The material used for the toothed segments is, for. B. pressed wood or cast wood in question. -You can also use natural wood and then choose the grain direction so The highest resistance is achieved.
