Description

Die Erfindung betrifft eine Entaschungsvorrichtung für Unterwindwanderroste, insbesondere Zonen-Unterwindwanderroste für Dampfkesselfeuerungen. Bei solchen Wanderrosten ist es bekannt, den Rostdurchfall ohne Windverlust aus den Zonenkästen unten durch aus Zellenrädern bzw. aus mit Längsschlitz versehenen Hohltrommeln bestehende Entaschungsvorrichtungen zu entfernen. Dabei besteht der Nachteil, daß die Entleerung auf das rücklaufende Rostband erfolgt. Es sind auch Entaschungsvorrichtungen für Zonen-Wanderroste bekannt, bei denen eine an ihrem Austragende durch einen umlaufenden Drehschieber abgeschlossene Förderschnecke benutzt wird. Bei jeder Umdrehung des Schiebers' wird der Auslauf einmal geöffnet. Diese bekannte Vorrichtung hat den Nachteil, daß der durch entsprechende Bemessung der Teile erstrebte Luftabschluß durch im Schneckenkanal verbleibende Asche bei der Anwendung höherer Luftpressungen unzureichend ist. Die einen dichten Luftabschluß ergebende Hinzufügung eines weiteren Drehschiebers mit Austragschnecke bedeutet einen erheblichen und nicht allgemein vertretbaren Aufwand an technischen Mitteln.The invention relates to an ash removal device for underwind wandering grates, in particular zone underwind grids for steam boiler firing. With such traveling grids it is known that the rust diarrhea without loss of wind from the zone boxes below Ash removal devices consisting of cellular wheels or hollow drums provided with a longitudinal slot to remove. There is the disadvantage that the emptying on the returning Grate band takes place. Ash removal devices for zone traveling grates are also known, one of which is closed at its discharge end by a rotating rotary valve Conveyor screw is used. With every turn of the slide the outlet open once. This known device has the disadvantage that by corresponding Dimensioning of the parts aimed for air exclusion by remaining in the screw channel Ash is insufficient when using higher air pressures. Some are poetic Addition of a further rotary valve with discharge screw resulting in air exclusion means a considerable and not generally justifiable expenditure on technical Means.

Die Erfindung vermeidet diese Nachteile dadurch, daß die Förderschnecke den Rostdurchfall aus (lern Zonenkasten einer als Schlitztrommel ausgebildeten luftdicht abschließenden Zellenradschleuse zuführt.The invention avoids these disadvantages in that the screw conveyor the grate diarrhea from (learn the zone box of an airtight drum designed as a slotted drum final rotary feeder feeds.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown in one embodiment.

Abb. i zeigt die Entaschungsvorrichtung im Längsschnitt, Abb. 2 im senkrechten Querschnitt.Fig. I shows the ash removal device in longitudinal section, Fig. 2 in vertical cross-section.

Im Boden jedes Zonenkastens eines Unterwindwanderrostes ist eine Schnecke i angebracht, die von der Welle 2 angetrieben wird. Die Schnecke fördert den Rostdurchfall in den außerhalb des Wanderrostes angeordneten Kasten 3, der unten durch das Zellenrad I luftdicht abgeschlossen wird, das die Form einer mit Längsschlitz ausgerüsteten Trommel besitzt. Welle 2 und Zellenrad .I werden gemeinsam vom Rost aus angetrieben. Durch das Zellenrad wird der Rostdurchfall ausgeschleust. Die Einrichtung nach der Erfindung bietet den Vorteil, daß das durch den Rost durchfallende Gut aus dem Rost herausgeschafft und unter Luftabschluß, d. h. ohne Druckverlust, ausgeworfen wird.There is a snail in the bottom of each zone box of an underwind grating i attached, which is driven by shaft 2. The snail promotes rust diarrhea in the outside of the traveling grate arranged box 3, which is down through the cellular wheel I is hermetically sealed, which has the shape of a fitted with a longitudinal slot Owns drum. Shaft 2 and cellular wheel .I are driven together from the grate. The grate diarrhea is discharged through the cell wheel. The establishment after the Invention has the advantage that the material falling through the grate from the grate removed and sealed off from the air, d. H. is ejected without loss of pressure.
