Description
Zellenradschleuse, insbesondere Durchblaseschleuse, für Anlagen zum Fördern von grob- oder feinkörnigem Gut mittels Preßluft Die Erfindung betrifft eine Zellenradschleuse, insbesondere eine Durchblaseschleuse, für Anlagen zum Fördern von grob- oder feinkörnigem Gut mittels Preßluft. Bei diesen mit Preßluft arbeitenden Zellenradschleusen besteht grundsätzlich das Problem, die Preßluft aus den leeren Zellen so abzuführen, daß kein Luftdurchtritt in den Materialeinlaufbereich der Schleuse stattfindet.Rotary lock, in particular blow-through lock, for systems for Conveying coarse or fine-grained material by means of compressed air The invention relates to a rotary valve, in particular a blow-through valve, for conveying systems of coarse or fine-grained material using compressed air. These work with compressed air Rotary feeders basically have the problem of removing the compressed air from the empty ones Discharge cells so that no air penetration into the material inlet area of the Lock takes place.
Erfindungsgemäß wird dieses Problem dadurch gelöst, daß in den Abführstutzen zur Druckförderleitung ein Zweigkanal einmündet, der von einer Öffnung des Schleusengehäuses ausgeht, an der sich die Zellen des Zellenrades nach der Entleerung vorbeibewegen.According to the invention this problem is solved in that in the discharge nozzle A branch channel opens to the pressure delivery line, which from an opening of the lock housing which the cells of the cellular wheel move past after emptying.
Vorteilhaft verläuft dabei der Zweigkanal mit Gefälle von der Schleuse zum Abführstutzen, denn so können Teile des Fördergutes, die in den Zellen zurückgeblieben waren, leichter in die Druckluftförderleitung gelangen. Zweckmäßig ist außerdem der Abführstutzen an der Einmündungsstelle des Zweigkanals düsenartig verengt, um eine Ejektorwirkung zu erzielen.The branch channel advantageously runs with a gradient from the lock to the discharge nozzle, because this allows parts of the conveyed material that remained in the cells were easier to get into the compressed air delivery line. It is also useful the discharge nozzle at the junction of the branch channel narrows like a nozzle to to achieve an ejector effect.
In der Zeichnung ist ein Ausführungsbeispiel des erfindungsgemäßen Schleusenanschlusses in perspektivischer Wiedergabe dargestellt. Dabei ist die vornliegende Seitenwand des Schleusengehäuses zum Teil entfernt und der Abführstutzen längs aufgeschnitten.In the drawing is an embodiment of the invention Lock connection shown in perspective rendering. Here is the one in front Side wall of the lock housing partially removed and the discharge nozzle cut open lengthways.
Im Gehäuse 1 der Zellenradschleuse läuft das Zellenrad 2 um. Ihr wird das Fördergut aus dem Aufgabebehälter 3 zugeführt und soll von ihr mit Hilfe der durch die Druckluftleitung 4 eingeleiteten Preßluft in den Abführstutzen 5, an den sich die nicht gezeichnete Förderleitung anschließt, abgeführt werden.The bucket wheel 2 rotates in the housing 1 of the rotary valve. Your will the conveyed material from the feed container 3 is supplied and is to be used by her with the help of the through the compressed air line 4 introduced compressed air into the discharge nozzle 5 to the the delivery line, not shown, is connected.
In den Abführstutzen 5 mündet ein schräg verlaufender Zweigkanal 6, der bis in eine Öffnung der Seitenwand des Schleusengehäuses 1 reicht. Diese Öffnung liegt in dem Bereich der Seitenwand, an dem die Zellen des Zellenrades 2 sich nach der Entleerung vorbei bewegen. An der Einmündungsstelle 7 ist der Abführstutzen 5 düsenartig verengt. Jede entleerte oder ungefähr entleerte Zelle 8 gelangt also noch einmal durch den Kanal 6 mit der Druckluftförderleitung bzw. deren Abführstutzen 5 in Verbindung. Durch Ejektorwirkung wird die noch in der betreffenden Zelle enthaltene Preßluft und das etwa zurückgebliebene Fördergut abgesaugt und gelangt noch mit in den abfließenden Luft-Fördergut-Strom.An inclined branch channel 6, which extends into an opening in the side wall of the lock housing 1, opens into the discharge nozzle 5. This opening is in the area of the side wall where the cells of the cellular wheel 2 move past after emptying. At the confluence point 7, the discharge nozzle 5 is narrowed like a nozzle. Each emptied or approximately emptied cell 8 is thus once again connected through the channel 6 with the compressed air delivery line or its discharge nozzle 5. The compressed air still contained in the cell in question and any remaining material to be conveyed is sucked out by the ejector effect and also enters the outflowing flow of air and material to be conveyed.
