Description
Mittelbar beheizte Trockentrommel Die Erfindung betrifft eine mittelbar beheizte Trockentrommel, bei der um einen inneren zylindrischen Kern herum längs der Trommelachse Kanäle für das zu trocknende Gut und längs den Wandungen dieser Kanäle Heizkanäle verlaufen, und besteht in der durch den Anspruch bezeichneten Gesamtanordnung, deren einzelne für sich allein oder in anderer Verbindung bekannte Merkmale als solche nicht beansprucht werden. Die Trommel gemäß der Erfindung ist wiederstandsfähig, gut zugänglich und hat einen geschlossenen Mantel; sie läßt sich von den Stirnwänden aus leicht überwachen und bewirkt schonende Guttrocknung. Die Trockenzellen können mit einer Schutzmetallauskleidung versehen werden.Indirectly heated drying drum The invention relates to an indirectly heated drying drum, in which around an inner cylindrical core lengthways the drum axis channels for the goods to be dried and along the walls of this Channels run heating channels, and consists in the one identified by the claim Overall arrangement, the individual known for themselves or in other connection Features as such are not claimed. The drum according to the invention is resistant, easily accessible and has a closed jacket; she lets herself Easily monitor it from the front walls and ensure gentle drying of the material. the Dry cells can be provided with a protective metal lining.
Auf der Zeichnung sind zwei Ausführungsformen der Trommel nach der Erfindung dargestellt.In the drawing are two embodiments of the drum according to the Invention shown.
Fig. i zeigt im Längsschnitt eine Ausführungsforin.Fig. I shows in longitudinal section an embodiment.
Fig. 2 zeigt im Längsschnitt eine weitere Ausführungsform.Fig. 2 shows a further embodiment in longitudinal section.
Fig. 3 und 4. sind Querschnitte durch die Ausführungsforen nach Fig. i.FIGS. 3 and 4 are cross-sections through the execution forums according to FIG. i.
Fig. j und 6 sind Querschnitte durch die Ausführungsform nach Fig. 2.FIGS. J and 6 are cross-sections through the embodiment according to FIG. 2.
Die Trockentrommel a ist 4uf Laufrollen b und b1 gelagert, von denen sie angetrieben wird. Die Laufrollen haben verschiedene Höhenlage, so daß die Trommel schräg gelagert ist, um das Gut bei der Drehung der Trommel von dein einen nach dem anderen Ende zu fördern. Durch Rohre c bzw. cl werden die Heizgase aus einem beliebigen Ofen zugeführt. Das Zuführungsrohr c bzw. cl reicht bis zu der Stirnwand d der Trommel.The drying drum a is mounted on rollers b and b1, by which it is driven. The rollers have different heights, so that the drum is mounted at an angle in order to convey the material from your one to the other end as the drum rotates. The heating gases are fed from any furnace through pipes c or cl. The feed pipe c or cl extends to the end wall d of the drum.
Bei der Ausführungsform nach Fig. i verteilen sich die Gase beim Eintritt in die Trommel auf die radial verlaufenden Heizkanäle e. Sie durchströmen diese bis zur Stirnwand dl und werden von dort in einen Abzug g bzw. g1 geleitet, von wo sie durch einen Exhaustor abgesaugt werden oder in einen Schornstein abziehen. Wie man aus Fig. i erkennt, ist die Heizgasführung in allen Kanälen gleichgerichtet.In the embodiment according to FIG. I, the gases are distributed on entry into the drum on the radially extending heating channels e. They flow through them up to the end wall dl and are passed from there into a fume cupboard g and g1, respectively where they are sucked off through an exhaustor or vented into a chimney. As can be seen from Fig. I, the heating gas flow is rectified in all channels.
Bei der Ausfehrungsform nach Fig.2 strömen die Heizgase zunächst durch ein mittleres Heizrohr f1 bis zu der Stirnwand dl. Von der Stirnwand dl ab gelangen die Heizgase rückströmend in radial um das Mittelrohr angeordnete Heizkanäle h. Sie gehen dann zurück etwa bis zur Stirnwand d. Von dort strömen sie weiter in am Umfang angeordnete Kanäle i bis zur Querwand d$, wo sie in dem Rohrkrümmer g1 gesammelt und mittels eines Exhaustors oder Schornsteins abgezogen werden.In the embodiment according to FIG. 2, the heating gases initially flow through a central heating pipe f1 up to the end wall dl. Get off the front wall dl the heating gases flowing back into heating channels arranged radially around the central tube h. You then go back approximately to the front wall d. From there they continue to flow into am Circumferentially arranged channels i up to the transverse wall d $, where they are collected in the pipe bend g1 and drawn off by means of an exhaustor or chimney.
Das feuchte Trockengut wird mittels einer Schürre k in die Beschickungskammer 1 Zr fördert. Es verteilt sich infolge der Drehbewegung und durch die Schräglage der Trommel selbsttätig auf die Trockenzellen m. Das Gut wird in einer Entleerungskammer n aufgefangen, um dann über den Rand der Trommel zur weiteren Beförderung abzugleiten.The moist dry material is fed into the loading chamber by means of a chute k 1 Zr promotes. It is distributed as a result of the rotary movement and the inclined position the drum automatically on the drying cells m. The material is in an emptying chamber n caught in order to then slide over the edge of the drum for further transport.
