Description

Die Erfindung betrifft einen DrehrohTofen zum Brennen von Zement oder ähnlichem Gut mit "um das Drehrohr außen herum angeordneten Kammern, die durch enge Schlitze oder ähnliche Mündungen mit dem Drehrohrinneren in Verbindung stehen und von den Brenngasen nicht unmittelbar berührt werden, und das Neue besteht darin, daß in den Kammern schaufelfförmi.ge Einbauten vorgesehen ,sind, die den Beginn und das Ende der Gutstreuung aus jeder Kammer in das Drehrohr beeinflussen.The invention relates to a rotary kiln for burning cement or Similar goods with "around the rotary tube arranged around the outside chambers, which by narrow Slots or similar mouths are connected to the interior of the rotary tube and are not directly touched by the combustion gases, and the new thing is that shovel-shaped internals are provided in the chambers, which begin and affect the end of the material spreading from each chamber into the rotary kiln.

Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung dar und zeigt in den Abb. i und 2 schematisch das Einlaufende eines Drehrohrofens in Längs- und Querschnitt, in Abb. 3 eine Einzelheit.The drawing shows an embodiment of the invention and shows in Figs. i and 2 schematically the inlet end of a rotary kiln in longitudinal and cross-section, in Fig. 3 a detail.

Der Drehrohrofen i (Abb. i und 2) ist mit dem Schamottefutter 2 ausgekleidet. Durch das Zulaufrohr 3 fließt das zweckmäßig vorgeformte trockene oder auch nasse Gut in den Drehrohrofen i und wird zunächst von spiralig vorgesehenen Druckschaufeln q. nach vorn geschoben. Es fällt dann durch Schlitze 5 in einen-das Drehrohr umgebenden Doppelmantel 6, der mit Stegen 7 in einzelne Kammern unterteilt ist. Dadurch wird das Gut mit nach oben genommen und fällt dann durch die jeweils oben befindlichen Schfitze 5 in einzelnen, ,breiten, zweckmäßig gegeneinander versetzten Schleiern durch den ganzen Querschnitt des Ofens, der allein von den Heizgasen durchströmt wird, welche schließlich durch die öffnung 8 in die Staubkammer 9 entweichen. Auf diese Weise erhält man in dem mit Schamottefutter ausgekleideten Drehrohr den vollen Querschnitt des Ofens zur Verfügung und verteilt das Gut durch die Kammerwände 7, die den Heizgasen nicht ausgesetzt sind, fortlaufend über den vorderen Ofenquerschnitt. Die Kammerwände 7 können dabei zum besseren Transport beliebig durchbrochen ausgebildet sein. Die Kammern besitzen gerade oder gekrümmte Vorsprünge 12, welche den Beginn und das Ende der Gutstreuung .so beeinflussen, daß tatsächlich der ganze Querschnitt- des Drehrohrofens fortlaufend mit Gutschleiern erfüllt wird. Es ist auch möglich, den äußeren Doppelmantel beliebig konisch zu gestalten.The rotary kiln i (Fig. I and 2) is lined with the chamotte lining 2. The expediently preformed dry or also wet flows through the inlet pipe 3 Well in the rotary kiln i and is initially provided by pressure blades provided in a spiral q. pushed forward. It then falls through slots 5 into one surrounding the rotary tube Double jacket 6, which is divided into individual chambers with webs 7. This will the goods are taken upwards and then falls through the one on top Schfitze 5 in individual, wide, appropriately staggered veils through the entire cross-section of the furnace, through which only the heating gases flow which finally escape through the opening 8 into the dust chamber 9. on in this way you get the full barrel lined with fireclay lining Cross-section of the furnace available and distributes the material through the chamber walls 7, that are not exposed to the hot gases, continuously across the front cross-section of the furnace. The chamber walls 7 can be designed to be perforated as desired for better transport be. The chambers have straight or curved projections 12, which the beginning and the end of the material spreading so that the entire cross-sectional of the rotary kiln is continuously filled with veils. It is also possible, to make the outer double jacket conical as desired.

Abb.3 zeigt eine gekrümmte schaufelartige Kammer 1q. mit gekrümmten Einbauten 15, die für eine gleichmäßige Gutsverteilung über die Schlitze 16 Sorge tragen.Fig.3 shows a curved blade-like chamber 1q. with curved Internals 15, which ensure an even distribution of material over the slots 16 wear.

Bei Einführung nassen Gutes werden im Doppelmantel und den Kammern sowie im Ofen. zweckmäßig Kettenoder ähnliches angebracht.When introducing wet goods are in the double jacket and the chambers as well as in the oven. appropriate chains or the like attached.

Jedenfalls kann auf diese Weise eine weitgehende Vorwärmung dies Gutes und eine weitgehende Herabsetzung der Austrittstemperatur ohne Gefährdung von Einbauten im Ofen selbst durchgeführt werden. Es ist möglich, dasselbe Verfahren zu verwenden beim Trocknen oder Kühlen von beliebigen Massengütern.In any case, extensive preheating can do this well in this way and a substantial reduction in the outlet temperature without endangering internal components be carried out in the furnace itself. It is possible to use the same procedure when drying or cooling any bulk goods.

Um ein eventuelles Verstopfen der Schlitze zu vermeiden, können in den Schlitzen Reinigungselemente, beispielsweise Ketten, vorgesehenwerden, oder es können die Schlitze von außen durch den Doppelmantel hindurch mittels Stangen gesäubert werden.To avoid any clogging of the slots, in cleaning elements, e.g. chains, are provided in the slots, or the slots can be passed through the double jacket from the outside by means of rods to be cleaned.
