Description

Abschlußvorrichtung an den Austragöffnungen des Kohlendurchfalles bei Unterwind-Wanderrosten Bei Unterwind-Wanderrosten ist es wichtig, den Kohlendurchfall, der in die Windkästen gelangt, dauernd ohne Verlust an Unterwind abzuführen. Die Austragöffnungen für diesen Kohlendurchfall müssen also dauernd gegen den Unterwind abgedichtet sein, andererseits muB aber auch der Kohlendurchfall .dauernd entfernt werden, da eine Ansammlung desselben im Unterwindkasten die Gefahr seiner Entzündung mit sich bringt.Closing device at the discharge openings of the coal fall with traveling grids under the wind In the case of traveling grids under the wind, it is important to prevent carbon diarrhea, which gets into the wind boxes, continuously dissipating without loss of underwind. the Discharge openings for this coal fall must therefore constantly against the downwind be sealed, but on the other hand the carbon diarrhea must also be permanently removed as an accumulation of the same in the underwind box increases the risk of its ignition brings with it.

Die Erfindung betrifft eine Vorrichtung zum Fördern des Kohlendurchfalles und zum gleichzeitigen Abdichten der Austrittsstelle. Sie ist in der Zeichnung im Schnitt dargestellt. Aus den Windkästen wird mittels einer Schnecke a, die in einem Austragrohr b liegt, der Kohlendurchfall nach dem Ende dieses Rohres gedrückt. Die Welle c der Schnecke a ist nach außen verlängert und läuft in einem Lager d. An das Rohr b ist eine oben offene Auslaufrinne e angeschlossen, durch welche der Kohlendurchfall f hindurchgeschoben wird, um an ihrem Ende bei g nach unten in Sammelbehälter oder in eine weitere Fördervorrichtung zu fallen. Auf der Welle c innerhalb der Auslaufrinne ist eine kleine Schneckeh aufgesetzt, derenDrehrichtung entgegengesetzt zu der Drehrichtung der Schnecke a ist.The invention relates to a device for conveying the carbon dioxide fall and for the simultaneous sealing of the exit point. It is in the drawing Section shown. From the wind boxes is by means of a screw a, which in a Discharge tube b lies, the coal fall is pressed after the end of this tube. the Shaft c of worm a is extended outwards and runs in a bearing d. At the pipe b is connected to a discharge channel e open at the top, through which the coal fall through f is pushed through to at its end at g down into collecting container or to fall into another conveyor. On the shaft c within the discharge channel a small snail is attached, the direction of rotation of which is opposite to the direction of rotation the snail is a.

Durch diese Vorrichtung wird erzielt, daß der in ,der Rinne e befindliche Kohlendurchfall in seiner Förderung verzögert wird, so daß sich an der Austrittsstelle des Austragrohres b bei i ein Anstau bildet.By this device it is achieved that the coal downfall in the channel e is delayed in its conveyance, so that an accumulation forms at the exit point of the discharge pipe b at i .

Wenn nun wenig oder gar kein Kohlendurchfall in den Windkasten und damit in das Austragrohr b gelangt, so würde ohne die gegenläufige Schnecke lt schon durch die Erschütterung der Auslaufrinne e (der feine Kohlendurchfall allmählich so weit abgefördert werden, daß der auch im Innern des Rohres b herrschende Überdruck die Luft nach außen blasen würde. Durch die gegenläufige Schnecke h wird aber der in der Rinne e befindliche Durchfall stets zusammengeschoben und vor der öffnung des Austragrohres bei i gestaut, so daß diese Öffnung gegen den Winddruck dauernd verschlossen ist.If there is little or no carbon diarrhea in the wind box and so that it gets into the discharge pipe b, it would already be without the counter-rotating screw by the shaking of the discharge channel e (the fine coal drop gradually be conveyed away so far that the overpressure also prevailing inside the tube b the air would blow out. But by the counter-rotating screw h the Diarrhea in groove e always pushed together and in front of the opening of the discharge pipe jammed at i, so that this opening is permanent against the wind pressure is locked.
