Die Erfindung bezieht sich auf Trockentrommeln, bei welchen durch Feuer erwärmte Luft in unmittelbarer Berührung mit den zu trocknenden Materialien gebracht wird. Derartige Trockentrommeln sind bereits bekannt, bei denen rechteckige, an einer Schmalseite offene Kammern in parallelen Reihen angeordnet sind, wobei die Trennwände der Kammern einer Reihe je in den Lichtraum der gegenüberliegenden Kammer hineinreichen. Bei Trockentrommeln dieser bekannten Bauart war jedoch die Wirkungsweise nicht in jeder Beziehung befriedigend. Die einzelnen Kammern dieser Trommeln konnten nur ver-The invention relates to drying drums which are heated by fire Air is brought into direct contact with the materials to be dried. Such Drying drums are already known in which rectangular, on one narrow side open chambers are arranged in parallel rows, with the partition walls of the chambers one row each into the clear space of the opposite chamber. In drying drums of this known type, however, the mode of operation was not in satisfactory in every relationship. The individual chambers of these drums could only be
*5 hältnismäßig wenig Material aufnehmen, da eine Anhäufung desselben nach dem Böschungswinkel kaum möglich war. Wies die Trommel eine geringfügige Mehrfüllung auf, so fiel hei der Drehung der Trommel das Material vom Trommelinnern nach dem äußeren Umfang hindurch, wo es sich in großen Mengen ansammelte, so daß die durch gleichmäßige Verteilung des Materials zu erzielende Ausbalancierung der Trommel und die dadurch bedingte Kraftverminderung unmöglich gemacht wurde.* 5 take up relatively little material because an accumulation of the same according to the angle of repose was hardly possible. Pointed the drum If there was a slight excess filling, the material fell as the drum rotated from the inside of the drum to the outer circumference, where it is in large quantities accumulated, so that the balance to be achieved by evenly distributing the material the drum and the resulting reduction in force was made impossible.
Zur Vermeidung dieses Ubelstandes werden gemäß vorliegender Erfindung die Rückwände der einzelnen Kammern einer Reihe stufenförmig gegeneinander versetzt und die Trennwände an der einen Seite der Kammer etwa doppelt so lang wie die Trennwände an der gegenüberliegenden Kammerseite gemacht. Infolge dieser Anordnung wird das Material in den Kammern ständig von drei Seiten begrenzt, wobei die Füllung der Kammern von dem Böschungswinkel des Materials vollkommen unabhängig wird. Die Bauart der vorliegenden Trockentrommel gestattet somit die Erreichung einer weitgehenden Füllung und einer dadurch bedingten besseren Wärmeausnutzung des Trommeleinbaues, wobei gleichzeitig ein Durchfallen des Materials vom Innern nach dem Trommelumfang völlig ausgeschlossen ist.To avoid this Ubelstandes the rear walls are according to the present invention the individual chambers of a row offset against each other in steps and the partition walls made on one side of the chamber about twice as long as the partitions on the opposite side of the chamber. As a result With this arrangement, the material in the chambers is constantly limited on three sides, the filling of the chambers is completely independent of the angle of repose of the material. The design of the present The drying drum thus enables a large amount of filling to be achieved and, as a result, a better utilization of heat of the drum installation, at the same time the material falling through from the inside according to the drum circumference is completely excluded.
Die Zeichnung veranschaulicht den Erfindungsgegenstand im senkrechten Querschnitt.The drawing illustrates the subject matter of the invention in vertical cross-section.
Im Innern der auf Rollen drehbar gelagerten Trommel sind die Schaufeln α durch die Querwände b derart miteinander vereinigt, daß sie mehrere, beispielsweise vier in Kreisabschnitten liegende Zonen und auf drei Seiten begrenzte Einzelkammern bilden, von denen je zwei verschiedener Zonen sich gegenüberliegen und mit ihren etwa um die Hälfte einer Kammerseite versetzten Schaufeln wechselseitig in bekannter Weise ineinandergreifen. In dieser Weise entsteht eine stufenförmige Anordnung der Rückwände b der einzelnen Kammern einer Reihe, wobei die Trennwände α an der einen Seite der Kammern etwa doppelt so lang wie die Trennwände an der gegenüberliegenden Kammerseite sind. Die Schaufeln c sind direkt an der inneren Trom-Inside the drum rotatably mounted on rollers, the blades α are united by the transverse walls b in such a way that they form several, for example four zones lying in circular segments and individual chambers delimited on three sides, of which two different zones are opposite each other and with their approximately blades offset by half of a chamber side mutually interlock in a known manner. This creates a stepped arrangement of the rear walls b of the individual chambers of a row, the partition walls α on one side of the chambers being approximately twice as long as the partition walls on the opposite side of the chamber. The blades c are directly on the inner drum

Die Vorwärtsbeförderung des Trockengutes wird durch die im Trommelinnern sich geltend machende Luftströmung bewirkt und durch geringe Schräglage der Trommel unterstützt.The forward conveyance of the dry material is applied by the inside of the drum causing air flow and supported by a slight inclination of the drum.
Der Einbau verteilt das Trockengut in kleineren Mengen auf den ganzen Trommelquerschnitt und bewirkt hierbei eine gleichmäßige Belastung der Trommel, wobei das Trockengut unter ständigem Umwenden bei jeder Trommeldrehung und Wandern innerhalb je zweier gegenüberliegender Kammern in innige Berührung mit der durchziehenden Heizluft gelangt, ohne daß es vom Trommelinnern nach dem äußeren Umfang der Trommel hindurchfallen kann. Durch die gleichmäßige Belastung wird aber zur Hervorrufung der Trommelbewegung weniger Kraft beansprucht und ein geringerer Verschleiß der Laufrollen und Laufkränze gewährleistet.The installation distributes the dry material in smaller quantities over the entire cross-section of the drum and causes an even load on the drum, with the material to be dried with constant turning over every drum rotation and wandering within two opposing chambers in intimate contact with the one passing through Heating air arrives without it from the inside of the drum to the outer circumference of the drum can fall through. Due to the even load, however, it becomes an evocation the drum movement requires less force and less wear on the rollers and running rings guaranteed.
In der Zeichnung ist die Verteilung des Materials sowie der zurückgelegte Weg durch punktierte Pfeile angegeben.In the drawing is the distribution of the material as well as the distance covered indicated by dotted arrows.
