Abstract

Die Erfindung betrifft eine Sandaustragungseinrichtung (1) für ein Schienenfahrzeug mit einem Vorratsbehälter (2) mit konisch zusammenlaufendem Boden und zumindest einem an der tiefsten Stelle des Bodens angeordneten Saugdüseneinsatz (5, 5'), der ein im Wesentlichen zylinderförmiges Gehäuse (6) mit einem nach unten offenen, in eine Sandförderleitung mündenden Hohlraum (7) aufweist, wobei der Saugdüseneinsatz (5, 5') von einem Druckluftstrom mit hoher Geschwindigkeit durchströmt wird. Weiters ist im Gehäuse (6) zumindest ein Saugkanal (10) für Sand angeordnet, der den Hohlraum (7) des Saugdüseneinsatzes (5, 5') mit dem Inneren des Vorratsbehälter (2) verbindet. Der Saugkanal (10) ist unter einem spitzen Winkel gegen die Mittelachse (16) des Gehäuses (6) nach unten geneigt und das Gehäuse (6) weist zumindest einen Belüftungskanal (13) mit einer Eintrittsöffnung (14) und einer Austrittsöffnung (15) auf, wobei die Austrittsöffnung (15) innerhalb der Sandaustragungseinrichtung (1) oberhalb der äußeren Öffnung (11) des Saugkanals (10) in den Vorratsbehälter (2) mündet.

The invention relates to a sand discharge device (1) for a rail vehicle with a reservoir (2) with conically converging bottom and at least one arranged at the lowest point of the bottom suction nozzle insert (5, 5 ') having a substantially cylindrical housing (6) with a has downwardly open, opening into a sand conveyor line cavity (7), wherein the suction nozzle insert (5, 5 ') is flowed through by a compressed air flow at high speed. Furthermore, in the housing (6) at least one suction channel (10) for sand is arranged, which connects the cavity (7) of the suction nozzle insert (5, 5 ') with the interior of the reservoir (2). The suction channel (10) is inclined at an acute angle towards the central axis (16) of the housing (6) downwards and the housing (6) has at least one ventilation channel (13) with an inlet opening (14) and an outlet opening (15) , wherein the outlet opening (15) within the sand discharge device (1) above the outer opening (11) of the suction channel (10) opens into the reservoir (2).
