Description

Speisevorrichtung für umlaufende Öfen zum Brennen von Zementschlamm. Es gibt ein Verfahren, bei dem Zementschlamm vor seinem Eintritt in den umlaufenden Ofen zur Ersparung von Brennstoff und zur Erhöhung der Leistungsmenge durch mechanische Mittel, wie Filter, bis zu einem gewissen Grade entwässert wird. Dieses Verfahren konnte aber bisher keinen Eingang in die Praxis finden, weil es schwierig ist, diese nur etwa 2o Prozent Wasser enthaltende plastische Masse in den umlaufenden Ofen durch mechanische Mittel, wie Förderschnecken, Fallrohre o. dgl., einzuführen. Die plastische Masse löst sich unter dem Einflug der Ofendrehung und der Hitze in einzelne Körper auerverschiedenster Größe, von der Staubform bis zu Ballen von 15 cm Durchmesser, auf, was ein ungleichmäßiges Brennen zur Folge hat. Den Gegenstand der Erfindung bildet eine Einrichtung, die ein regelrechtes, gleichmäßiges Speisen eines umlaufenden Ofens mit mechanisch getrocknetem Zementschlamm und dadurch ein gleichmäßiges Brennen ermöglicht.Feeding device for rotary kilns for burning cement slurry. There is a process in which cement slurry is circulating before it enters the Furnace to save fuel and to increase the amount of power through mechanical Means, such as filters, are dehydrated to a certain extent. This method but has not yet found its way into practice because it is difficult to do this Plastic mass containing only about 20 percent water in the circulating furnace by mechanical means such as screw conveyors, downpipes or the like. To introduce. the plastic mass dissolves under the influx of the furnace rotation and the heat in individual Bodies of various sizes, from the form of dust to balls of 15 cm in diameter, on, which results in uneven burning. The subject the invention forms a device that a regular, even meal a rotating furnace with mechanically dried cement slurry and thereby a Allows even burning.

Wie die Zeichnung an einem Ausführungsbeispiel schematisch darstellt, besteht diese Einrichtung in einer Strangpresse e bekannter Einrichtung, die den aus einer beliebigen mechanischen Entwässerungsvorrichtung a kommenden Zementschlamm empfängt und die außerhalb des die Gase des Ofens d aufnehmenden Schachtes g aufgestellt ist, so daß die mechanisch bewegten Teile durch die Hitze dieser Gase nicht leiden. Ein Rohr f leitet den von der Strangpresse vorwärts getriebenen, entwässerten Schlammstrang durch den Schacht g in den umlaufenden Ofen d.As the drawing shows schematically in an exemplary embodiment, this device consists of an extruder e known device that the cement slurry coming from any mechanical dewatering device a receives and placed outside the shaft g receiving the gases from the furnace d so that the mechanically moving parts do not suffer from the heat of these gases. A pipe f conducts the dewatered strand of sludge driven forward by the extruder through the shaft g into the circulating furnace d.

Zweckmäßig ist es, das Rohr f, wie in der Zeichnung dargestellt, doppelwandig auszuführen, so daß man imstande ist, es durch Einführung von Luft oder Wasser in den >Mantelraum kühl zu halten. In dem Rohre f wird der Schlamm stark zusammengedrückt und bildet ein festes Formstück, das eine genügend harte Oberfläche besitzt, die es durch die Pressung gegen die noch immer hinreichend heiße Rohrwand erhält. Beim Austritt aus dem Rohre f zerbricht der Strang in einzelne gleichartige Stücke, die den Ofen durchwandern und so in gleichmäßiger und regelrechter Weise gebrannt werden.It is useful, the pipe f, as shown in the drawing, double-walled carried out so that one is able to do so by introducing air or water into to keep the> jacket room cool. The sludge is strongly compressed in the pipe f and forms a solid molding which has a sufficiently hard surface that it is retained by pressing against the pipe wall, which is still sufficiently hot. At the Leaving the tube f breaks the strand into individual pieces of the same type, which wander through the kiln and so be fired in an even and regular manner.

Es steht natürlich nichts im Wege, vor dem umlaufenden Ofen zum Zwecke weiterer Trocknung des Zementschlammes durch Wärme eine Trockentrommel einzuschalten und dieser den Schlamm in der beschriebenen Weise zuzuführen.Of course, there is nothing in the way of the rotating oven for the purpose switch on a drying drum for further drying of the cement slurry by means of heat and to supply the sludge to it in the manner described.
