Description

Schacht zum Trocknen, Kühlen, Rösten o: dgl. Die Erfindung bezieht sich auf einen Schacht, in welchem durch Einwirkung eines von unten eintretenden Luft- oder gasförmigen Mittels, im folgenden mit Luft bezeichnet, ein Trocknen, Kühlen, Rösten oder andere Behandlung von Gut aller Art vorgenommen werden soll. Beispielsweise ist die Einrichtung gemäß der Erfindung für das Kühlen von Zementklinkern geeignet. Zwecks gleichmäßigerVerteilung der Luft wird diese durch ein von unten in die Masse des Gutes hineinragendes, von einer Haube überdecktes Einführungsrohr eingeblasen, damit sie sich in dem zu behandelnden Gut gleichmäßig ausbreiten kann. Bei schwerem oder zum Zusammenbacken neigendem Gut kann nun der Widerstand, welchen die Gutsäule der aufsteigenden Luft entgegensetzt, so groß werden, daß die Luft teilweise nach unten hin durch die Austragseinrichtung zu entweichen sucht, und zwar vorzugsweise an derSchachtwand und dem Zuführungsrohr entlang. In besonders starkem Maße tritt dies ein, wenn der Schacht nach unten hin trichterförmig ausgebildet ist, wie dies meist der Fall ist, um die Verengung des Schachtquerschnitts durch das Luftzuführungsrohr und die Abdeckhaube auszugleichen oder um eine zu schnelle Austragung des Gutes zu verhindern.Chute for drying, cooling, roasting or the like. The invention relates on a shaft in which by the action of one entering from below Air or gaseous means, hereinafter referred to as air, a drying, Cooling, roasting or other treatment of all kinds of goods should be carried out. For example, the device according to the invention is for cooling cement clinker suitable. In order to distribute the air evenly, it is fed through from below Infeed tube that protrudes into the mass of the goods and is covered by a hood blown in so that it can spread evenly in the material to be treated. In the case of heavy goods or goods with a tendency to stick together, the resistance can now determine which the column of good opposed to the rising air, become so large that the air partially seeks to escape downward through the discharge device, and preferably along the shaft wall and the feed pipe. Especially this occurs to a large extent when the shaft is funnel-shaped towards the bottom is, as is usually the case, around the narrowing of the shaft cross-section to compensate for the air supply pipe and the cover hood or to avoid a too fast To prevent the goods from being carried away.

Die Erfindung schafft hiergegen dadurch Abhilfe, daß die Schachtwand in ihrem unteren trichterförmigen Teil mit Stauvorrichtungen ausgerüstet ist, in denen sich Gut ablagert und den Durchtritt der Luft nach unten hin verhindert. Auch an dem Rohr zur Einführung der Luft werden zweckmäßig solche Stauvorrichtungen an der Außenseite angebracht. - Als derartige Staumittel kommen vorzugsweise waagerecht herumlaufende Stauringe oder Vorsprünge in Betracht.The invention provides a remedy for this in that the shaft wall is equipped with damming devices in its lower funnel-shaped part, in where good is deposited and prevents the passage of air downwards. Even Such damming devices are expediently attached to the pipe for introducing the air attached to the outside. - Such stowage means are preferably horizontal running around retaining rings or projections into consideration.

Die Zeichnung stellt ein Ausführungsbeispiel gemäß derErfindung dar und zeigt einen senkrechten Schnitt durch einen zum Kühlen, Trocknen, Rösten oder für ähnliche Zwecke dienenden Schacht.The drawing shows an embodiment according to the invention and shows a vertical section through one for cooling, drying, roasting or shaft used for similar purposes.

Die Wandung des Schachtes z trägt in ihrem unteren Teil eine Anzahl Rippen 2, welche derart nach aufwärts gerichtet sind, daß sich das niedergehende Gut auf ihnen ablagern kann. Auch die Zuleitung 3 für die Luft ist an der Außenseite mit ähnlichen Rippen 4 besetzt. Sowohl die Wandungen des Schachtes als auch die Leitungen erhalten daher eine genügend rauhe Oberfläche, um den Durchtritt von Luft o. dgl. nach unten hindurch zu verhindern.The wall of the shaft z carries a number in its lower part Ribs 2, which are directed upwards in such a way that the descending Can well deposit on them. The supply line 3 for the air is also on the outside occupied with similar ribs 4. Both the walls of the shaft and the Lines are therefore given a sufficiently rough surface to allow air to pass through o. The like. Down through to prevent.
