Description

Verfahren zur Beheizung von Trockentrommeln Die Erfindung soll einem längst vorliegenden Bedürfnis nach einem Trockner für gleichzeitige Ausnutzung von Abdampf und Abgase für Trocknungszwecke abhelfen.Method for heating drying drums The invention is intended to provide a there has long been a need for a dryer for simultaneous use of Remove steam and exhaust gases for drying purposes.

Der Trockner ist für alle rieselfähigen Stoffe bestimmt, welche mit Feuergasen nicht in Berührung gebracht werden dürfen. Er besteht aus der eigentlichen Trockentrommel a, welche zwischen den Lagerungen von der Heizkammer b eingeschlossen wird, ferner aus dem Lufterhitzer c, der Lufteintrittskammer d, dem Abluftauslaßgehäuse e und dem Exhaustor f.The dryer is designed for all free-flowing substances that contain Fire gases must not be brought into contact. It consists of the actual Drying drum a, which is enclosed between the bearings of the heating chamber b is, furthermore from the air heater c, the air inlet chamber d, the exhaust air outlet housing e and the Exhaustor f.

Der Arbeitsvorgang im Trockner ist folgender: Das Naßgut wird in den Aufgalbetrichter g eingefüllt und gleitet aus diesem in die Drehtrommel a. Hier wird es durch die am Anfang angeordneten Spiralbleche h in die durch die Wände! und das Dampfrohr k gebildete Zellen gefördert, in welchen es bei Drehung der Trommel abwechselnd von dem durch Abgase von Dampfkesseln oder anderen industriellen Feuerungen beheizten Trommelumfang nach der dampfbeheizten Kammer h und wieder zum Umfang zurückrieselt. Statt eines Rohres von größerem Durchmesser kann aber auch ein Röhrenbündel, aus mehreren Rohren von kleinerem Durchmesser bestehend, in der Trommelmitte angeordnelt werden.The working process in the dryer is as follows: The wet material is poured into the Aufgalereinichter g and slides out of this into the rotating drum a. Here it is through the spiral sheets arranged at the beginning h into the through the walls ! and the steam pipe k conveyed cells formed in which, when the drum rotates, it alternately trickles from the drum circumference heated by exhaust gases from steam boilers or other industrial furnaces to the steam-heated chamber h and back again to the circumference. Instead of a tube with a larger diameter, however, a tube bundle consisting of several tubes with a smaller diameter can be arranged in the center of the drum.

Die Feuergase oder Abgase irgendeiner anderen Feuerungsanlage treffen bei L in die Heizkammer b ein, umspülen die Trommel, durch eingebaute Leitwände zwangläufig geführt, in Spiralwindungen und werden schließlich bei m wieder abgesaugt.Meet the flue gases or flue gases from any other combustion system at L into the heating chamber b, wash around the drum through built-in guide walls inevitably guided, in spiral windings and are finally sucked off again at m.

Als drittes Heizmittel wird Heißluft verwendet. Diese wird auf zwei verschiedene Weisen erhitzt. Ein Teil :der dazu nötigen Frischluft strömt durch die in den Wänden der Heizkammer angebrachten öffnungenn. in die in den Wänden befindlichen Zwischenräume o und erhitzt sich hier an dem heißen Mauerwerk, dieses gleichzeitig abkühlend. Die Erhitzung wird durch eingebaute Blechwände p noch gesteigert. Die so erhitzte Luft strömt dann durch die Verbindungskanäle q in die Lufteintrittskalnmer d und von hier in die Trommel. Der zweite Teil der Trockenluft tritt als Frischluft bei t' in den Lufterhitzer c, in welchem die Luft durch die vorteilhaft auch mit Abdampf beheizten Rippenrohres erhitzt wird. Auch diese Heißluft strömt durch die Lufteintrittskammer d in die Trockentrommel. Die so .erzeugte Heißluft durchströmt die Trommel nun. im Gegenstrom zum Trockengut und wird nach dem Durchgang aus dem AbluftausJa.ßgehäuse! e von dem Exhaustor f abgesaugt.Hot air is used as the third heating means. This will be on two heated different ways. One part: the fresh air required for this flows through the openings made in the walls of the heating chamber. in the ones in the walls Gaps o and heats up here on the hot masonry, this at the same time cooling. The heating is increased by built-in sheet metal walls p. the Air heated in this way then flows through the connecting ducts q into the air inlet duct d and from here into the drum. The second part of the dry air occurs as fresh air at t 'in the air heater c, in which the air is also advantageous with Exhaust steam heated finned tube is heated. This hot air also flows through the Air inlet chamber d in the drying drum. The hot air generated in this way flows through the drum now. in countercurrent to the dry material and is after the passage from the Exhaust air outlet housing! e sucked off from the exhaustor f.

Das getrocknete Gut wird durch die Ausziehschnecke t aus der Trommel abgeführt.The dried material is removed from the drum by the extraction screw t discharged.
