Description

Die Erfindung betrifft einen Schachtofen zum Brennen von Zement und ähnlichem Gut, bei dem der Ofenquerschnitt in der Vorwärm- und Entsäuerungszo-ne eingezogen, ist, um die Sinterz.one gegenüber dieser verhältnismäßig groß zu halten und dadurch das Auftreten von. Randfeuer- zu vermeiden. Naturgemäß muß das Gut durch diese Vorwärm- und Entsäuerungszone verhältnismäßig schnell hindurchgefördert werden, und um dies zu begünstigen, ist gemäß der Erfindung hier eine Einrichtung zum Fördern der Beschickung vorgesehen, beispielsweise ein Kolben.The invention relates to a shaft furnace for burning cement and Similar good, in which the furnace cross-section in the preheating and deacidification zone is drawn in, in order to keep the sintering zone relatively large compared to this and thereby the appearance of. Avoid rimfire. Naturally, the good has to go through this preheating and deacidification zone are conveyed through relatively quickly, and in order to facilitate this, according to the invention here is a device for conveying the charge provided, for example a piston.

Die Zeichnung stellt schematisch ein Ausführungsbeispiel der Erfindung dar. Sie zeigt einen Schachtofen in senkrechtem Schnitt. An den Hauptabschnitt 1 des Ofens, in welchem sich eine eine verhältnismäßig geringe Höhe aufweisende Sinterzone A bildet, schließt nach oben eine Zone a an, in welcher das durch den Einlauf 3 zugeführte Frischgut vorgewärmt und entsäuert wird und die sich kegelig nach oben verengt. In diesem verengten Teil ist ein Kolben 4 vorgesehen, der durch einen nicht dargestellten Antrieb im Sinne des Doppelpfeiles B auf- und abgeschoben werden kann. Durch dieses Bewegen des Kolbens 4 wird das eingefüllte Gut in der verengten Zone stärker abwärts bewegt als durch sein bloßes Eigengewicht.The drawing shows schematically an embodiment of the invention. It shows a shaft furnace in vertical section. The main section 1 of the furnace, in which a relatively low height sintering zone A is formed, is followed by a zone a at the top, in which the fresh material supplied through the inlet 3 is preheated and deacidified and which narrows conically upwards. In this narrowed part, a piston 4 is provided, which can be pushed up and down in the direction of the double arrow B by a drive (not shown). As a result of this movement of the piston 4, the filled product is moved more downward in the narrowed zone than by its mere own weight.

Im unteren, zum Kühlen dienenden Teil 5 des Schachtofens ist ein Austragerost 6 vorgesehen, der den erbrannten Klinker zur Austrageschleuse 7 fördert. Die Brennluft wird durch das Gebläse 8 unten in den SdharJhtofen eingeleitet.In the lower part 5 of the shaft furnace, which is used for cooling, there is a discharge grate 6 provided, which promotes the burnt clinker to the discharge lock 7. The combustion air is introduced by the fan 8 into the bottom of the SdharJhtofen.
