Description
Vorrichtung zur Verhinderung von Grubenexplosionen mittels Gesteinsstaub. Die bisher im Bergbaubetriebe zwecks Verhinderung von Grubenexplosionen zur Verwendung gekommenen Staubverteiler haben sich mehr oder minder als unwirksam erwiesen. Bei den bekannten Ausführungen wird der Staub nicht restlos dem Mundstück zugeführt, sondern entweicht teilweise durch den Füllrumpf nach außen. Diese Nachteile werden durch Gegenstand vorliegender Erfindung beseitigt. Die Zeichnung veranschaulicht einen derartigen Staubverteiler, und zwar Abb. x im Querschnitt nach Linie A-B, Abb. 2 im Grundriß.Device for preventing mine explosions using rock dust. Previously used in mining operations to prevent mine explosions Any dust distributors that have come have proven to be more or less ineffective. at In the known designs, the dust is not completely fed to the mouthpiece, but partially escapes through the filling hull to the outside. These disadvantages will be eliminated by subject matter of the present invention. The drawing illustrates such a dust distributor, namely Fig. x in cross section along line A-B, Fig. 2 in plan.
Die Neuerung besteht im wesentlichen darin, daß in dem Füllrumpf a ein Blechkegel b in Verbindung mit der nach unten gerichteten Strahldüse d derartig angeordnet ist" daß der Gesteinsstaub durch den freien Zwischenraum c je nach Entnahme dem Mundstück des Füllrumpfes a selbsttätig zugeführt wird und die austretende Preßluft denselben durch den Schlauch zur Verwendungsstelle drückt, so daß ein Entweichen aus dem Füllrumpf nach oben hin ausgeschlossen ist.The innovation consists essentially in the fact that in the filling hull a a sheet metal cone b in connection with the downwardly directed jet nozzle d of this type is arranged "that the rock dust through the free space c depending on the extraction the mouthpiece of the filling hull a is automatically supplied and the exiting compressed air pushes the same through the hose to the point of use, so that an escape is excluded from the filling hull towards the top.
