Description

Trockentrommel mit längslaufenden, nur an ihrer freien Längskante aufgebogenen Hebeblechen. Um die Wärme der Trockengase oder Trockenluft in Trockentrommeln gut auszunutzen, sind sie meist mit längslaufenden Hebeblechen versehen, die ,an ihrer freien Längskante aufgebogen sind, um das Trockengut bei der Drehung der Trommel auf möglichst großem Bogen mitzunehmen. Hierbei rieselt das Gut über die Vorderkante der längslaufenden Bleche in Längsschleiern ab, zwischen denen nun aber kanalartige freie Räume verbleiben. Die durch diese Räume hindurchznehenden Trockengase werden nicht genügend ausgenutzt.Drying drum with longitudinal, only on its free longitudinal edge bent lifting plates. To heat the drying gases or drying air in drying drums good to use, they are usually provided with longitudinal lifting plates, the their free longitudinal edge are bent up to allow the material to be dried when the drum rotates to take with you on as large a sheet as possible. The material trickles over the front edge of the longitudinal sheets in longitudinal veils, but now channel-like between them free spaces remain. The drying gases flowing through these spaces become not sufficiently exploited.

Dem wird erfindungsgemäß dadurch abgeholfen, daß die Hebebleche mit schmalen, in kurzen Abständen aufeinanderfolgenden Querschlitzen versehen sind. Durch diese fällt ein Teil des Trockengutes bei Drehung der Trommel hindurch, so daß sich also außer den bekannten Längsschleiern auch dünne Querschleier bilden, die von den Heizgasen durchströmt werden.This is remedied according to the invention in that the lifting plates with narrow, at short intervals successive transverse slots are provided. Part of the material to be dried falls through this when the drum rotates, see above that in addition to the known longitudinal veils, thin transverse veils also form, through which the heating gases flow.

An sich ist es bekannt, die längslaufenden Hebebleche zu unterbrechen. Das ist aber aus rein baulichen Gründen vorgeschlagen worden, ohne daß dabei bewußt die Bildung von Querschleiern erstrebt worden ist, .und es sind auch die bekannten unterteilten Ausbildungen der Hebebleche nicht in der Lage, während des Dauerbetriebes Querschleier zu erzeugen. Man hat einesteils statt der Hebebleche einzelne Schaufeln angewendet, bei denen das Schaufelblech seitlich hochgebogen ist. Hierbei wird die Bildung von. Querschleiern geradezu durch die hochgiebogene Seitenränder behindert. Sodann hat man, um die Hebeblecheinbauten herausziehbar zu machen, diese in achs:ial aufeinanderfolgende Gruppen unterteilt. Zwischen den aufeinanderfolgenden Gruppen weisen die Hebebleche Unterbrechungen auf. An diesen stellt sich aber sehr bald-ein Böschungswinkel ein, so daß während des Betriebes dann tatsächlich nur über die Längskanten der Hebebleche das Trockengut in Längsschleiern herabrieselt. Bekannt ist hierbei sowohl die Anordnung der Hebebleche der einzelnen Gruppen in fortlaufenden Ebenen oder zueinander versetzt, was aber in den gerügten Nachteilen nichts ändert. Erfindungsgemäß sind aber die Schlitze schmal und folgen in kurzen Abständen aufeinander, so daß sie keine Seitenbegrenzung der Hebebleche im eben erwähnten Sinne darstellen, sich also während der Arbeit an den Schlitzen kein Böschungswinkel ausbildet, sondern das Arbeitsgut dauernd durch die Schlitze ebenso wie über die Längsvorderkanten abrieselt und wegen der üblichen Geneigtlage der Trockentrommel zum Teil auch auf die andere Schlitzseite übertritt.It is known per se to interrupt the longitudinal lifting plates. But this has been suggested for purely structural reasons, without being aware of it the formation of transverse veils has been sought, and there are also known ones subdivided training of the lifting plates not able to work during continuous operation To create transverse veils. On the one hand, you have individual blades instead of the lifting plates used in which the blade plate is bent up to the side. Here the Formation of. Transverse veils are virtually hindered by the high-arched side edges. Then you have to pull out the lifting plate fixtures in achs: ial successive groups divided. Between the consecutive Groups have the lifting plates on interruptions. But there is a lot to do with this soon-an angle of repose, so that during operation then actually only The dry material trickles down in longitudinal veils over the longitudinal edges of the lifting plates. The arrangement of the lifting plates in the individual groups is known here continuous levels or offset to each other, but what in the criticized disadvantages nothing changes. According to the invention, however, the slots are narrow and follow in short Clearances on each other so that there is no side limit to the lifting plates in the flat represent the mentioned senses, so there is no angle of repose while working on the slots trains, but the work material continuously through the slots as well as over the The longitudinal leading edges trickle down and because of the usual incline of the drying drum partly also crosses over to the other side of the slot.

Auf der Zeichnung ist en Ausführungsbeispiel teils im Querschnitt, teils im Längsschnitt mit Angabe der Drehrichtung dargestellt. In den Hebeblechen sind quer zur Längsrichtung liegende Schlitze e vorgesehen. Diese Schlitze folgen verhältnismäßig dicht, d. h. in kurzen Entfernungen aufeinander, und jeder der Schlitze ist verhältnismäßig schmal. Dadurch entstehen die aus den Zeichnungen ersichtlichen Querschleier, die scheibenartig in ihrer Gesamtheit den Querschnitt überdecken - außerdem rieselt auch Arbeitsgut über die Längskanten (s. bei a).In the drawing, an exemplary embodiment is partly in cross-section, partly shown in longitudinal section with indication of the direction of rotation. In the lifting plates slits e lying transversely to the longitudinal direction are provided. These slots follow relatively dense, d. H. at short distances to each other, and each of the slots is relatively narrow. This creates what can be seen in the drawings Cross veils that cover the cross-section in their entirety like a disk - In addition, work material also trickles over the longitudinal edges (see a).

Um große Fallhöhen zu vermeiden und etwa empfindliches Trockengut zu schonen, empfiehlt es sich, die Schlitze c in den einzelnen Blechen gegeneinander zu versetzen (s. Längsschnitt).To avoid great heights of fall and sensitive items to be dried To conserve it, it is advisable to juxtapose the slots c in the individual metal sheets to move (see longitudinal section).
