. Injektordüse zum Fördern von Feststoffen in Behälter mit Überdruck. In jector nozzle for conveying solids into containers with overpressure

Ih der Verfahrenstechnik ergibt sich oft die Aufgabe, Feststoffe in unter höherem Druck stehende Behälter einzubringen. Dies kann mittels Schleusen geschehen. Es ist aber oft vorteilhaft* mittels Injektordüsen diese Aufgabe zu lösen, vor allem dann, wenn der Feststoff als feinkörniges Schüttgut vorliegt und sowieso schon bis zum Behälter pneumatisch gefördert wurde. " ·In process engineering, the task often arises Bring solids into containers under higher pressure. This can be done using locks. However, it is often advantageous * to perform this task using injector nozzles to solve, especially when the solid is in the form of a fine-grained bulk material and in any case up to the container was conveyed pneumatically. "·

Die bisher bekannten Injektordüsen weisen einen sehr langen, sich in Strömungsrichtung konisch verjüngenden Mischraum auf, dem sich dann ein zylindrischer Teil und daran ein mit relativ großem öffnungswinkel versehenes Erweiterungsrohr anschließen.The previously known injector nozzles have a very long, tapering conically in the direction of flow Mixing space, which is then a cylindrical part and on it a one provided with a relatively large opening angle Connect the extension pipe.

Diese Aufgabe wurde durch eine Injektordüse, wie sie im Anspruch gekennzeichnet ist, gelöst.This object was achieved by an injector nozzle as characterized in the claim.

Anhand der Abbildung wird die neue Injektordüse beschrieben. The new injector nozzle is described using the illustration.

Aus einem Druckspeicher oder einer Sammelleitung strömt das Fördermedium, z. B. L/uft, durch die Treibdüse 1, deren engster Durchmesser d ist. An die Treibdüse 1 schließt sich die sogenannte Staudüse an, die aus dem Mischraum 2 und dem Erweiterungsrohr 3 mit dem Öffnungswinkel y besteht. Die Länge des Mischraumes 2, die sogenannte Mischstrecke a, wird vom Treibdüsenende in Strömungsrichtung bis zum engsten Querschnitt der Staudüse (Durchmesser D) gemessen. Über dem Mischraum 2 ist der Schüttguttrichter 4 angeordnet, so daß sich das Schüttgut mit dem Fördermedium am Treibdüsenende trifft. ■ ■ ·The pumped medium flows from a pressure accumulator or a collecting line, e.g. B. Air, through the propellant nozzle 1, the narrowest diameter of which is d. The so-called stagnation nozzle, which consists of the mixing chamber 2 and the extension pipe 3 with the opening angle y , is connected to the propellant nozzle 1. The length of the mixing space 2, the so-called mixing section a, is measured from the drive nozzle end in the direction of flow to the narrowest cross section of the stagnation nozzle (diameter D). The bulk material hopper 4 is arranged above the mixing chamber 2, so that the bulk material and the conveying medium meet at the end of the propellant nozzle. ■ ■ ·
