Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei mit Dampf beheizten Trockentrommeln, z. B. der Papier- und Textilindustrie, besteht der Übelstand, daß der zugeführte Dampf sich an der Trommelwandung abkühlt und niederschlägt und das Niederschlagswasser aus der Trommel abgeführt werden muß. Dies bedingt, daß dauernd die Dampfzufuhr erneuert werden muß, was einen erheblichen Brennstoffverbrauch bedingt.In the case of steam-heated drying drums, e.g. B. the paper and textile industry the inconvenience that the supplied steam cools down on the drum wall and precipitates and the rainwater out the drum must be removed. This means that the steam supply is constantly renewed must be, which requires a significant fuel consumption.

ίο Dort wo elektrische Energie billig zur Verfügung steht, wie bei Betrieben mit Wasserkräften, kann man den Brennstoffverbrauch dadurch einschränken, daß in dem Dampfraum der Trockentrommel elektrische Heizkörper angeordnet sind, welche dem Dampf Wärme zuführen. Hierdurch wird der Wärmeverlust, den der Dampf durch Berührung mit der Trommelwandung erleidet, ergänzt und die Temperatur in der Trommel auf einer solchen Höhe gehalten, daß ein Niederschlagen des Dampfes nicht oder in nur unerheblichem Maße eintritt. Man erreicht dabei noch die günstige Wirkung, daß durch die Zwischenschaltung des Dampfes zwischen elektrischen Heizkörper und Trommelmantel örtliche Oberhitzungen des letzteren vermieden werden.ίο Wherever electrical energy is available cheaply stands, as in operations with water power, you can limit the fuel consumption in that in the steam room Electric heating elements are arranged in the drying drum, which add heat to the steam. This reduces the heat loss, which the steam suffers from contact with the drum wall, and the temperature in the drum on one held at such a height that precipitation of the steam is not or only insignificant Dimensions enters. One still achieves the beneficial effect that through the interposition of the steam between electrical Radiator and drum jacket local overheating of the latter can be avoided.

Eine beispielsweise Ausführungsform einer Trockentrommel gemäß der Erfindung ist in der Zeichnung in Fig. ι in einem Längsschnitt, und inAn example embodiment of a drying drum according to the invention is shown in FIG the drawing in Fig. ι in a longitudinal section, and in

Fig. 2 in einem Schnitt nach Linie A-A der Fig. ι schematisch dargestellt.Fig. 2 is shown schematically in a section along line AA of Fig. Ι.

Die Trockentrommel 1 besitzt hohle Zapfen 2 und 3. Durch den Zapfen 2, an den eine Leitung 4 angeschlossen ist, wird der Dampf in die Trommel geleitet. In dieser sind elektrische Heizkörper 5 (in der Zeichnung schematisch angedeutet) angeordnet, und zwar hauptsächlich am Umfang der Trommel, wo die Abkühlung des Dampfes erfolgt. Die Stromzuführung nach den Heizkörpern erfolgt von B aus durch den Zapfen 2. Mit 6 ist ein Schöpfwerk bezeichnet, das etwaiges Niederschlagswasser durch den hohlen Zapfen 3 und Leitung 7 aus der Trommel abführt.The drying drum 1 has hollow pins 2 and 3. The steam is passed into the drum through the pin 2, to which a line 4 is connected. In this electric heater 5 (indicated schematically in the drawing) are arranged, mainly on the circumference of the drum, where the cooling of the steam takes place. The power is supplied to the radiators from B through the pin 2. 6 denotes a pumping station, which removes any rainwater through the hollow pin 3 and line 7 from the drum.
