Description
Verfahren und Vorrichtung zum Körnen von Schlacke.Method and apparatus for granulating slag.
Gegenstand der Erfindung ist ein Verfahren und eine Vorrichtung zum Körnen von Schlacke, wobei diese nur so wenig Feuchtigkeit annimmt, daß die noch vorhandene Wärme des Korns diese Feuchtigkeitsmenge zum Verdunsten bringen kann. Auf diese Weise findet ein selbsttätiges Trocknen der gekörnten Schlacke statt. Die Erfindung l esteht darin, daß die flüssige Schlacke in einen in einer geneigten ;Rinne fließenden Wasserstrom geleitet und kurz danach die gekörnte Schlacke von der Wasserströmung über einen in der Rinne liegenden Rost hinweg wieder aus der Rinne herausbefördert wird, während das Wasser durch den Rost abfließt. The invention relates to a method and a device for Grains of slag, whereby it only absorbs so little moisture that it still Existing heat of the grain can cause this amount of moisture to evaporate. In this way, the granular slag dries automatically. The invention l est is that the liquid slag in an inclined ; Channel flowing water flow and shortly afterwards the granular slag from the water flow over a grate lying in the channel away from the The channel is conveyed out while the water drains through the grate.
Auf der Zeichnung ist eine Ausführungsform der Vorrichtung zur Ausübung des Verfahrens im Schnitt dargestellt. Die Schlacke fl eßt idurch eine Rinne I in schnell sftömendes Wasser 2, aus dem sie gekörnt wieder an die Oberfläche steigt, wo sie infolge der Wasserströmung auf einen Schwimmer 3 geschoben wird, der zweckmäßig schräg gelagert ist, so daß die Schlacke von dem Schwimmer auf einer Rinne6 abwärts, z. B. in einen Wagen geleitet wird. In the drawing is an embodiment of the device for exercising of the procedure shown in section. The slag flows through a channel I in fast flowing water 2, from which it rises back to the surface in granular form, where it is pushed onto a float 3 as a result of the water flow, which is expedient is inclined so that the slag from the float on a channel6 downwards, z. B. is directed into a car.
Damit von dem Wasser die Schlackenkörner nicht mitgerissen werden, ist an dem Schwimmer ein Rost 4 befestigt, der die Schlackenkörner auffängt. Der Rost ist gleichfalls schräg angeordnet, so daß die Wasserströmung die Körner an ihm entlang auf den Schwimmer schiebt. Dieser ruht auf dem Wasser, das unter ihm nach einem Fallrohr 5 strömt. Die Schlacke ist nur derart kurze Zeit mit dem Wasser in Berührung, daß die einzelnen Körner nur außen abgeschreckt, nicht aber vollständig ausgekühlt werden. Infolgedessen bewirkt die in den Körnern noch vorhandene Wärme ein Verdunsten des auf ihrer Oberfläche haftenden Wassers, wodurch die Körner vollkommen getrocknet werden. So that the slag grains are not carried away by the water, a grate 4 is attached to the float, which catches the slag grains. Of the The grate is also arranged at an angle so that the water flow to the grains pushes along him on the float. This rests on the water below it after a downpipe 5 flows. The slag is only with the water for such a short time in contact that the individual grains are only quenched on the outside, but not completely be cooled down. As a result, causes the heat still present in the grains an evaporation of the water adhering to their surface, making the grains complete to be dried.
