Description

Die Erfindung betrifft eine Verbesserung und \rereinfachung des Verfahrens und der Vorrichtung des Hauptpatentes 330065, und zwar soll die Abführung der sich bildenden Brüden sowie die Abkühlung des Stuckgipses an der Auslaufstelle und die Einstellung der Brenntemperatur in bequemer Weise beeinflußt und herbeigeführt werden können. Das Verfahren besteht darin, daß ein durch eine Regelvorrichtung einstellbarer Luftstrom im Gegenstrom durch den Riingraum gesaugt und darauf in den Schornstein abgeleitet wird. Damit zur weiteren Vereinfachung des Verfahrens von der Anordnung eines besonderen Exhaustors zur Absaugung des Feinen und der entstehenden Brüden abgesehen werden kann, ist der Anfangsschuß der Drehtrommel derart siebartig ausgebildet, daß das mit aufgegebene feine Gut durch diesen Siebschuß hindurchfällt und sofort anderweitig verwendet werden kann.The invention relates to an improvement and \ r IMPLIFICATION of the method and apparatus of the main patent 330 065, specifically to the removal of the forming vapors and cooling the stucco to the discharge point and the setting of the combustion temperature can be influenced in a convenient manner and brought about. The method consists in that an air flow adjustable by a control device is sucked in countercurrent through the ring space and then discharged into the chimney. In order to further simplify the process, it is possible to dispense with the arrangement of a special exhaustor for suctioning off the fines and the resulting vapors, the initial section of the rotary drum is designed in the form of a sieve that the fine material also falls through this sieve section and can be used for other purposes immediately.

Die Zeichnung veranschaulicht eine beispielsweise Ausführungsfomi des Verfahrens. Mittels des trichterförmigen Einlaufes am Brenntrommelende α gelangt der Rohgips in den Ringraum b der BrenntiOmmel. Eine wesentliche Vereinfachung des Verfahrens nach dem Hauptpatent liegt in der Abführung der sich in diesem Ringraum bildenden Brüden aus dem Ringraum b. Diese Brüden werden in einfachster Weise durch den Schornstein f abgesaugt, zu welchem Zweck die Abgasrohrleitung durch eine Haube g umschlos- . sen ist, die mit dem Schornstein in Verbindung steht. LTm jederzeit mehr oder weniger Frischluft über das Brenngut führen zu können, ist am Ende der Trommel, und zwar zweckmäßig am Miauerwerk, ein RegeAungsorgan h, ein Ringschieber o. dgl. angeordnet, so daß neben der Regelung der Frischluft zugleich auch eine Regelung der Brenntemperatur in weiten Grenzen herbeigeführt werden kann.The drawing illustrates an exemplary embodiment of the method. By means of the funnel-shaped inlet at the end of the firing drum α , the raw plaster of paris gets into the annular space b of the firing drum. A significant simplification of the process according to the main patent lies in the removal of the vapors that form in this annulus from the annulus b. These vapors are sucked off in the simplest way through the chimney f , for which purpose the exhaust pipe is enclosed by a hood g. that is connected to the chimney. L T m to be able to lead more or less fresh air over the material to be fired at any time is at the end of the drum, expediently on the meowing, a regulating element h, a ring slide o the firing temperature can be brought about within wide limits.

Wie auch bei dem Haiuptpatent vorgesehen, ist die Brenntrommel mit Schaufeln versehen, welche die annähernd gleich großen Gipsstücke auf die heißen Wandungen des Außenrohres und des Innenrohres c werfen, so daß alle Flächen der Einzelstücke mit ihnen in Berührung kommen und ein möglichst gleichmäßiges Durchbrennen erzielt wird. Da das innere die Feuerungsabgase zum Schornstein führende Rohr c nicht mit der äußeren Drehtrommel umläuft, sondern feststeht, kann ein Durchbiegen des inneren Rohres dadurch vermieden wenden, daß das Rohr etwa in der Mitte der Trommel durch einen Schleifring gehalten wird. Ebenso kann über dem Rohr ein Dach o. dgl. angeordnet sein, um ein Ab-· lagern des Brenngutes auf dem festen Rohr 6c zu vermeiden.As also provided for in the main patent, the firing drum is provided with blades which throw the almost equally large pieces of plaster onto the hot walls of the outer tube and inner tube c , so that all surfaces of the individual pieces come into contact with them and burn through is as even as possible . Since the inner pipe c leading the combustion exhaust gases to the chimney does not rotate with the outer rotary drum, but is fixed, bending of the inner pipe can be avoided by holding the pipe approximately in the middle of the drum by a slip ring. A roof or the like can also be arranged over the pipe in order to prevent the material to be fired from being deposited on the fixed pipe 6c.
