Vorrichtung zur Bildung einer Suspension fester, pulverförmiger Stoffe in einem Träger- gas zum Zwecke der Einführung in ein Metallbad
EMI1.1
<Desc/Clms Page number 2>
Die Platte 15 und die Düsen) 16 werden durch die Leitung 17 versorgt, jedoch kann dies ebenso aus der Hauptleitung erfolgen.
Wenn die Speisung der Leitung 1 ausfällt, so fällt in der Leitung 17 der Druck rasch auf einen sehr kleinen Wert, während es einige Zeit dauert, bis der Druck in der Leitung 20 abnimmt. Im Augenblick des Ausfalles öffnet sich das Einwegventil 18 für den Durchtritt von Gas, welches sich unter Druck in der Leitung 20 und im Oberteil des Behälters befindet. Dadurch bildet sich in der Leitung 17 ein gewisser Gasdruck aus, welcher zur Beaufschlagung der verschiedenen porösen Platten und Düsen für eine gewisse Zeit nach dem Ausfall des Gasdruckes in der Leitung 1 ausreicht. Es besteht dann keine Gefahr, dass sich verschiedene Teile im Verlaufe des Fliessens des pulverförmigem Materials verstopfen könnten.
PATENTANSPRÜCHE :
1. Vorrichtung zur Bildung einer Suspension fester, pulverförmiger Stoffe in einem Trägergas zum Zwecke der Einführung in ein Metallbad, dadurch gekennzeichnet, dass die Trägergashauptleitung, welche eine Venturidüse oder eine andere Düse speist, die an einer Stelle angeordnet ist, wo das pulverförmige Material in den Gasstrom eingeführt wird, mit einem regelbaren Ventil ausgestattet ist, vor welchem die das Absetzen und Hängen verhindernden Einrichtungen und nach welchem eine Leitung grossen Querschnittes, die im Oberteil des Vorratsbehälters für das pulverförmige Material mündet, angeschlossen sind.

Device for the formation of a suspension of solid, powdery substances in a carrier gas for the purpose of introduction into a metal bath
EMI1.1
<Desc / Clms Page number 2>
The plate 15 and the nozzles 16 are supplied by the line 17, but this can also be done from the main line.
If the feed to the line 1 fails, the pressure in the line 17 falls rapidly to a very small value, while it takes some time for the pressure in the line 20 to decrease. At the moment of failure, the one-way valve 18 opens for the passage of gas which is under pressure in the line 20 and in the top of the container. This creates a certain gas pressure in line 17, which is sufficient to act on the various porous plates and nozzles for a certain time after the gas pressure in line 1 has failed. There is then no risk that various parts could become clogged in the course of the flow of the powdery material.
PATENT CLAIMS:
1. Device for forming a suspension of solid, powdery substances in a carrier gas for the purpose of introduction into a metal bath, characterized in that the carrier gas main line, which feeds a Venturi nozzle or another nozzle, which is arranged at a point where the powdery material in the gas flow is introduced, is equipped with a controllable valve, in front of which the devices preventing settling and hanging and after which a line of large cross-section, which opens into the upper part of the storage container for the powdery material, is connected.
