Description

Trockentrommel, in welcher der Länge nach stern-, kreuz- oder winkelförmige Rieseleinbauten angeordnet sind Bei den bisher bekannten Rieseleinbauten von Trockentrommeln geht die Bewegung, insbesondere das Herabrieseln des Gutes innerhalb des Einbaues über die ganze Länge jeder einzelnen Rieselfläche hin gleichzeitig vor sich, so daß sich zwischen dem herabrieselnden Gut zwangsläufig Kanäle bilden müssen, durch welche das Gas durchtritt, ohne das Gut zu berühren. Um nun diesem Übelstande abzuhelfen, wurde bekannterweise vorgeschlagen, die sich in der Längsrichtung der Trommel erstreckenden Rieseleinbauten um ihre eigenen Achsen zu verwinden, wodurch sowohl eine ständige Auflösung und Verteilung des Gutes bewirkt als auch die Bildung von Gaskanälen unterbunden werden soll, indem das Gut ständig und regelmäßig den Gasstrom durchschneidet.Drying drum in which the length is star, cross or angular Drainage baffles are arranged in the previously known trickle baffles of drying drums is the movement, especially the trickling down of the goods within the installation over the entire length of each individual trickle surface simultaneously in front of you, like this that channels inevitably have to form between the trickling down goods which the gas passes through without touching the goods. In order to remedy this evil, it has been proposed, as is known, to extend in the longitudinal direction of the drum Trickle installations to twist their own axes, creating both a permanent Dissolution and distribution of the material causes as well as the formation of gas channels prevented should be in that the material constantly and regularly cuts through the gas flow.

Dieser bekannten Ausführungsart der Rieseleinbauten haftet nun der große Mangel an, daß bei den üblichen Stern-, kreuz- oder winkelförmigen Profilen der Einbauten diese in einer gewissen gegenseitigen Stellung liegen müssen, wenn eine ordnungsgemäße Rieselbewegung stattfinden soll. Bei kreuzförmigen Einbauten nach Abb. i z. B. müssen je vier kreuzförmige Einbauten, welche zusammen eine Zelle bilden, in der dargestellten Weise zueinander liegen, damit während einer Trommeldrehung das Trockengut entsprechend oft und tunlichst aufgelöst (wie punktiert, Abb. i) von einer Leiste auf die andere rieselt und nebenbei in der aus den vier Kreuzen gebildeten Einbauzelle während der Trommeldrehung verbleibt. Werden nun die Einbauten um ihre eigene Achse fortlaufend verwunden, z. B. im Sinne des Pfeiles, so wäre bereits nach einer Verdrehung um den Winkel a (Abb. i) die sehr ungünstige Stellung der vier Kreuze gemäß Abb. a erreicht. Das Trockengut würde bei einer solchen gegenseitigen Stellung überhaupt nicht mehr rieseln, sondern nur, in dem Quadrat zusammengeballt, herumrutschen. Verfolgt man die gegenseitige Stellung der vier kreuzförmigen Einbauten bei einer weiteren Verwindung um die eigene Achse, so ergibt sich, daß nur eine bestimmte gegenseitige Stellung für die Gleichmäßigkeit und Oftmaligkeit des Rieselvorganges sowie die gleichmäßige Erfüllung des ganzen Trommelquerschnittes mit Trockengut die beste sein kann und daß die meisten anderen in dieser Hinsicht überhaupt unbrauchbar sind.This known embodiment of the trickle installations is now liable great lack of that with the usual star, cruciform or angular profiles of the internals these must be in a certain mutual position, if a proper trickle movement should take place. With cross-shaped fixtures according to fig. B. need four cross-shaped internals, which together form a cell form, lie to one another in the manner shown, so that during a drum rotation Dissolve the dry goods as often and as much as possible (as dotted, Fig. i) trickles from one bar to the other and incidentally in the one from the four crosses built-in cell remains during the rotation of the drum. Now are the fixtures continuously wound around their own axis, e.g. B. in the direction of the arrow, it would be the very unfavorable position already after a rotation by the angle a (Fig. i) of the four crosses shown in Fig. a. The dry goods would in such a mutual Position no longer trickle at all, but only, clumped together in the square, slide around. If one follows the mutual position of the four cross-shaped fixtures with a further twist around its own axis, it results that only one certain mutual position for the evenness and frequency of the trickling process as well as the uniform filling of the entire drum cross-section with dry material can be the best and that most of the others are useless at all in this regard are.

Auch bei stern- und winkelförmigen Einbauten liegen die Verhältnisse ähnlich, wie sie für kreuzförmige vorstehend geschildert wurden; nur eine bestimmte gegenseitige Stellung solcher Einbauten ist für deren Arbeitsweise die beste, während alle anderen dagegen schlechter bzw. ganz unbrauchbar sind.The same applies to star-shaped and angled internals similar to those outlined above for cruciforms; only a certain one mutual position of such internals is the best for their functioning while all others, however, are worse or completely useless.

Erfindungsgemäß werden nun die Vorteile, welche Einbauten, die um ihre eigene Längsachse verwunden sind, bringen sollen, ohne die dieser Art bei stern-, kreuz- oder winkelförmigen Einbauten anhaftenden Nachteile dadurch erreicht, daß solche Einbauten um die Mittelachse der Trommel als die allen Einbauten gemeinsame Schraubenachse nach Abb. 3 verwunden werden, wodurch die gegenseitige Stellung der einzelnen Einbauten über die ganze Trommellänge die gleiche bleibt.According to the invention, the advantages, which internals, the order their own longitudinal axis are twisted, should bring, without this kind of star, cruciform or angular internals adhering disadvantages achieved in that such internals around the central axis of the drum as those common to all internals Screw axis are twisted according to Fig. 3, whereby the mutual position of the individual fixtures remain the same over the entire length of the drum.
