Description

Mischdüse für Asche-Ejektoren Die Mischdüsen bei Asche-Ejektoren für Spülentaschungen sind besonders bei Förderung von Schlacken einem hohen Verschleiß unterworfen. Dieser Verschleiß wird durch die Schleifwirkung des die Düse passierenden Schlackenbreies hervorgerufen.Mixing nozzle for ash ejectors The mixing nozzles for ash ejectors for Sink ash removal is particularly subject to high wear when pumping slag subject. This wear and tear is caused by the abrasive action of what passes through the nozzle Caused cinder slurry.

Die Mischdüse gemäß der Erfindung, bei der die wirksame Düsenfläche von Kugeln begrenzt wird, hat den bekannten Einrichtungen gegenüber den Vorteil, daß ein Abrollen des Schlackenbreies ermöglicht ist, so daß die Düse bzw. deren wirksame Fläche wesentlich geringer beansprucht wird als die wirksame Fläche einer festen Düse.The mixing nozzle according to the invention, in which the effective nozzle area is limited by balls, has the advantage over the known devices, that a rolling of the slag is enabled, so that the nozzle or its effective area is used much less than the effective area of a fixed nozzle.

Der äußere Düsenkörper a (s. Zeichnung) liegt fest und dient als Lauffläche für Kugeln b, deren Durchmesser sich nach den Betriebsverhältnissen richten. Eine Korbdüse hält die auf den Umfang verteilten Kugeln in ihren Lagerstellen fest; diese innere Düse (Korbdüse) kann sich in dem feststehenden Teil des Düsenkörpers frei drehen. Außerdem können sich die Kugeln in ihren Lagerstellen frei bewegen. Die Korbdüse ist gegen Herausfallen gesichert.The outer nozzle body a (see drawing) is fixed and serves as a running surface for balls b, the diameter of which depends on the operating conditions. One Basket nozzle holds the balls distributed around the circumference in their bearings; these inner nozzle (basket nozzle) can freely move into the fixed part of the nozzle body turn. In addition, the balls can move freely in their bearings. the The basket nozzle is secured against falling out.

Der Zwischenraum zwischen dem festen und dem beweglichen Teil der Mischdüse kann an eine Druckleitung angeschlossen werden, die in diesem Teil der Düse einen Überdruck erzeugt, um das Eindringen von Schlackenbrei in den Hohlraum zu verhindern.The space between the fixed and moving parts of the Mixing nozzle can be connected to a pressure line in this part of the Nozzle creates an overpressure to prevent slag from entering the cavity to prevent.
