Description

Vorrichtung zum Trocknen oder Abschwelen feinkörniger Nassen in stetigem Betrieb Das Hauptpatent schützt eine Vorrichtung zum Trocknen oder Abschwelen feinkörniger Massen in stetigem Betrieb mit einem vom Heizmittel und vom Behandlungsgut durchflossenen Behälter, der dadurch gekennzeichnet ist, daß Heizmittel und Trocken-at in getrennten Strömen durch den Behälter fließen und der Wärmeübergang durch leicht erwärmbare Körper erfolgt, die kreisend oder schwingend erst zur Wärmeaufnahme den vom Heizgas durchströmten Raum durchwandern und dann zur Wärmeabgabe in die Masse des Behandlungsguts eintauchen.Device for drying or liming fine-grained wet in steady Operation The main patent protects a device for drying or degreasing fine grains Masses in continuous operation with one through which the heating medium and the material to be treated flow Container, which is characterized in that heating means and dry gas in separate Currents flow through the container and the heat transfer through easily heatable Body takes place that circling or swinging only to absorb heat from the heating gas wander through the flowed-through space and then to give off heat into the mass of the material to be treated immerse.

Diese Wärmeaustauschvorrichtung soll in erster Linie als Ersatz für die bisher üblichen Drehtrommeln dienen, wobei einerseits das Drehen der schweren Trommel vermieden, besonders aber erreicht werden sollte, daß ein Durcheinanderwirbeln von Heizmittel und Trockengut verhindert wird; denn hierbei werden die staubförmigen Teile des Trockenguts von dem Heizmittelstrom aufgenommen und gehen verloren.This heat exchange device is primarily intended as a replacement for the previously common rotary drums are used, on the one hand turning the heavy ones Avoid drumming, but what should be achieved in particular is to prevent it from being whirled around is prevented by heating medium and dry goods; because this is where the dusty Parts of the dry material absorbed by the heating medium flow and are lost.

Gegenstand der zusätzlichen Erfindung ist eine Ausführungsform, die in Verbindung mit der Drehtrommel verwendet werden kann. Diese Bauart ist nützlich in besonderen Fällen und wird hauptsächlich bei der Verarbeitung solcher Trockengüter zu verwenden sein, die weniger zur Staubbildung sowie zum Anbacken an der Trommelwand neigen. Dreht man die Trommel nur langsam, so wird man bei derartigen Trockengütern erreichen können, daß das Durcheinanderwirheln von Trockengut -und Heizmittel in schädlichen Maße vermieden wird. Die -Neigung, eine derartige Anordnung zu wählen, liegt hauptsächlich dann vor, wenn vorhandene Drehtrommeln verwendet werden sollen; um gleichzeitig die Vorteile, die die Wärmeaustauschkörper gemäß der Erfindung bieten, nutzbar zu machen, ohne die erheblich größeren Kosten für eine neue Behälteranlage aufzuwenden.The additional invention is an embodiment that can be used in conjunction with the rotating drum. This type of construction is useful in special cases and is mainly used when processing such dry goods to be used, the less dust and sticking to the drum wall tend. If you turn the drum slowly, you will be able to handle such dry goods can achieve that the confusion of drying material and heating means in harmful dimensions are avoided. The tendency to choose such an arrangement occurs mainly when existing rotary drums are to be used; at the same time to take advantage of the advantages offered by the heat exchange body according to the invention, can be used without the considerably higher costs of a new container system to spend.

Nach der Erfindung sollen bei einer Vorrichtung zum Trocknen oder Abschivelen feinkörniger Massen in stetigem Betrieb gemäß Patent 466 925 die Wärmeaustauschkörper an der drehbar gelagerten Trommelwand starr befestigt sein.According to the invention, in a device for drying or peeling off fine-grained masses in continuous operation according to patent 466 925, the heat exchange body should be rigidly attached to the rotatably mounted drum wall.

Die Schwierigkeiten, die sich bezüglich der getrennten Zuführung von Heizmittel und Behandlungsgut ergeben, können dadurch vermieden werden, daß erfindungsgemäß die Wärmeaustauschkörper mit der Trommelwand und einem mittleren Verdrängungskörper zu einem Drehkörper starr verbunden sind, der zwischen den feststehenden Stirnwänden um seine Mittelachse kreist.The difficulties that arise regarding the separate feeding of Resulting heating means and items to be treated can be avoided that according to the invention the heat exchange body with the drum wall and a central displacement body to a rotating body are rigidly connected between the fixed End walls circling around its central axis.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung schematisch in senkrechtem Schnitt durchTdie Mittelachse gezeigt.An embodiment of the subject matter of the invention is shown in the drawing shown schematically in a vertical section through the central axis.

Die Trommel a' ist in der bei Drehtrommeln üblichen Weise auf Rollböcken s, s' um ihre Mittelachse drehbax gelagert. Der Antrieb kann in üblicher Weise mittels eines Zahnkranzes t erfolgen. Die zylindrische Trommelwand ist mit den Trommelstirnwänden p, p' nicht starr verbunden, sondern diese sind unter Einfügung einer Dichtung in den Trommelmantel eingepaßt. Sie können infolgedessen in der oberen Hälfte einen Heizmitteleinlaß f -und einen Heizmittelauslaß g, in der unteren Hälfte einen Einlaß d und einen Auslaß e für das Behandlungsgut aufweisen.The drum a 'is on trestles in the manner customary with rotary drums s, s' rotatably mounted about their central axis. The drive can in the usual way by means of of a ring gear t take place. The cylindrical drum wall is aligned with the drum end walls p, p 'are not rigidly connected, but these are with the insertion of a seal in fitted to the drum shell. As a result, you can have one in the top half Heizmitteleinlaß f - and a Heizmittelauslaß g, in the lower half an inlet d and an outlet e for the material to be treated.

Die in Form von durchbrochenen Kreisscheiben c ausgebildeten Wärmeaustauschkörper sind an dem Trommelmantel a', dessen Querschnitt sie vollständig ausfüllen, starr befestigt, desgleichen in der Mitte an einem Verdrängungskörper r, der so groß gewählt ist, daß der für den Wärmeaustausch unnütze Mittelteil der Trommel verkleinert wird.The heat exchange body designed in the form of perforated circular disks c are on the drum shell a ', the cross-section of which they completely fill, rigid attached, also in the middle of a displacement body r, which is chosen so large is that the central part of the drum that is useless for heat exchange is reduced in size.

Die Wirkungsweise der Vorrichtung ist derart, daß das Behandlungsgut bei d einläuft und durch die Länge der Trommel nach dem Auslaß e abläuft. Dieses Ablaufen kann durch Erhöhung des Gefälles, beispielsweise durch Neigung der Trommel- vom Einlaß nach dem Auslaß,. begünstigt werden, desgleichen wirkendie Wärmeaustauschkörper c vorschiebend auf das Gut. Die Wärmeaustauschkörper erhitzen .sich an den den oberen Teil der Körper durchströmenden Heizgaseu und geben diese Wärme im unteren Teil an das Trocken-oder Verschwelungsgat ab.The operation of the device is such that the material to be treated enters at d and runs down the length of the drum to outlet e. This Drainage can be achieved by increasing the slope, for example by inclining the drum from inlet to outlet ,. are favored, the heat exchange bodies act in the same way c advancing on the property. The heat exchangers heat up on the upper ones Part of the body flowing through heating gases and give this heat in the lower part to the drying or carbonization gate.
