Description

Austragseinrichtung für Reaktionsräume Die Erfindung bezieht sich auf eine Austragseinrichtung für Reaktionsräume, bei welcher durch das auszutragende Material Dichnmgspfropfen gebildet werden. Eine solche Austragseinrichtung kann z. B. bei der Herstellung von Fluor-Wasserstoffsäure aus Flußspat und Schwefelsäure zum Abführen des als Nebenprodukt entstehenden Anhydtites aus dem Re aktionsofen verwendet werden.Discharge device for reaction spaces The invention relates to a discharge device for reaction spaces, in which by the to be discharged Material sealing plugs are formed. Such a discharge device can z. B. in the production of hydrofluoric acid from fluorspar and sulfuric acid to remove the anhydrite formed as a by-product from the reaction furnace be used.

Das Neue gemäß der Erfindung besteht darin, daß die Einrichtung ein Austragsgehäuse mit Labyrinthgängen aufweist, wobei in jedem Gang eine Förderschnecke untergebracht ist, welche vor der Übergangsstelle zwischen den einzelnen Labyrinthgängen aufhört, so daß an den Üb ergangs stellen zwischen den einzelnen Gängen dichtende Materialpfropfen entstehen. Bei dieser Ausbildung muß das Gas mehrere Pfropfen passieren. Durch die damit erreichte Addition der zur Erreichung einer Dichtheit des Pfropfens zulässigen Druckunterschiede wird ein Arbeiten mit höheren Drücken im Reaktionsofen ermöglicht. The novelty according to the invention is that the device is a Has discharge housing with labyrinth passages, with a screw conveyor in each passage is housed, which is in front of the transition point between the individual labyrinth passages ceases, so that at the transition points between the individual courses sealing Material plugs arise. In this training, the gas must pass several plugs. Through the addition achieved in this way to achieve a tightness of the plug permissible pressure differences will work with higher pressures in the reaction furnace enables.

Zweckmäßigerweise werden dieLabyrinthgänge durch Zwischenwände so voneinander getrennt, daß ein durchgehender Förderweg entsteht.The labyrinth passages are expediently made by partition walls separated from each other that a continuous conveying path is created.

In der Zeichnung ist ein Ausführungsbeispiel des Ertindflngsgegenstandes dargestellt. In the drawing is an embodiment of the object of the invention shown.

Mit 1 ist das Auslaufende eines Reaktionsraumes, z. B. das Auslaufende eines Reaktionsofens zur Erzeugung von Fluor-Wasserstoffsäure bezeichnet, welches Auslaufende über einen Stutzen 2 mit dem Ge häuse 3 der Austragseinrichtung in Verbindung steht. With 1 is the outlet end of a reaction chamber, z. B. the end of the line of a reaction furnace for the production of hydrofluoric acid, which Outflow via a nozzle 2 with the Ge housing 3 of the discharge device in connection stands.

Das Gehäuse 3 weist Labyrinthgänge4, 5, 6 und 7 auf, welche durch Zwischenwände8, 9 und 10 so voneinander getrennt sind, daß ein durchgehender Förderweg entsteht. Der Labyrinthgang 7 steht mit einem Auslaufstutzen 11 in Verbindung.The housing 3 has labyrinth passages 4, 5, 6 and 7, which through Partitions 8, 9 and 10 are separated from each other so that a continuous conveying path arises. The labyrinth passage 7 is connected to an outlet nozzle 11.

In jedem Labyrinthgang 4, 5, 6 und 7 ist je eine Förderschnecke 12, 13, 14 und 15 vorhanden, welche das Material durch die Gänge 4 bis 7 und schließlich durch den Auslaufstutzen 11 fördert. Die Anordnung der Schnecken ist dabei so getroffen, daß jede Schnecke vor der Übergangsstelle 16 bzw. 17 bzw. 18 zwischen den einzelnen Labyrinthgängen aufhört. In dieser Weise entstehen im Bereich der tJbergangsstelle Materialpfropfen 19, 20, 21 und 22, welche eine vollständige Abdichtung der Gänge bilden und jede Gasentweichung verhindern. In each labyrinth passage 4, 5, 6 and 7 there is a screw conveyor 12, 13, 14 and 15 are available, which the material through aisles 4 to 7 and finally promotes through the outlet nozzle 11. The arrangement of the snails is made in such a way that that each screw before the transition point 16 or 17 or 18 between the individual Labyrinth ceases. In this way arise in the area of the transition point Material plugs 19, 20, 21 and 22, which completely seal the aisles and prevent any gas leakage.

Jede Schnecke 12, 13, 14 und 15 weist eine Antriebswelle 23, 24, 25 und 26 auf, welche durch die Stirnwand 27 des Gehäuses 3 ins Freie ragen und von einer gemeinsamen Welle 28 angetrieben werden, die durch Kupplungen 29 unterteilt ist. Zum Antrieb der Welle 28 dient ein Motor 30 mit Getriebe 31. Each worm 12, 13, 14 and 15 has a drive shaft 23, 24, 25 and 26, which protrude through the end wall 27 of the housing 3 into the open and are driven by a common shaft 28, the divided by clutches 29 is. A motor 30 with gear 31 is used to drive the shaft 28.

Wie aus der Zeichnung hervorgeht, sind die Gänge 4 bis 7 etagenweise übereinander angeordnet. As can be seen from the drawing, aisles 4 to 7 are on each floor arranged one above the other.

Die Schnecken können dabei senkrecht oder schräg üb ereinanderliegen.The screws can lie vertically or diagonally one above the other.
