Description

Vorrichtung zum Fördern von staubförmigem Gut durch Luft aus dem Vorratsbehälter in- den Gebrauchsbehälter von Bunkern Bei der Förderung von staubförmigem Gut ,aus Bunkern an die Verbrauchsstellen mittels Saugluft zeigt sich oft der Übelstand, daß das im Bunker liegende Gut infolge einer gewissen Neigung zum Backen schlecht nachrutscht, indem sich Brücken und Nester bilden. Man hat daher bereits mittels eines besonderer Gebläses Druckluft in den unteren Teil des Bunkers durch dort eingebaute Düsen in das Gut eingeblasen, um das Nachrutschen zu sichern. Die Erfindung besteht nun darin, daß man die zu erzielende Gesamtwirkung der Förderung und Aufwirbelung mit einem einheitlichen Gebläse hervorbringt, indem dessen Saugseite in üblicher Weise an den Staubabscheider des Gebrauchsbehälters, dessen Druckseite aber an eine AuflockerLUlgsclüse im unteren Teil des Vorratsbunkers angeschlossen ist. Auf diese Weise wird mit einfachsten Mitteln eine sehr wirksame, keinen Stockungen ausgesetzte Förderung des Staubgutes unter Vermeidung von. Staubverlusten mit der entweichenden Luft erzielt. Zwar ist es an sich bereits bekannt,, bei reiner Druckluftförderung den Druckluftstrom zu teilen, indem man einen Teilstrom in eine Auflockerungsdüse leitet, den anderen, größeren; zur Förderung selbst benutzt. Aber es besteht hierbei keine genügende Sicherung gegen das Entweichen von staubhaltiger Luft aus dem Gebrauchsbehälter, so daß diese Einrichtung für sehr feinkörniges Gut nicht ausreicht. Auch die bekannten Druckluftdüsen, die am Boden eines Silos angebracht sind, um dessen Inhalt in einen darunter angebrachten Behälter zu entleeren, tragen dem Umstand nicht Rechnung, - daß die im oberen Teil des Behälters abziehende Luft noch staubhaltig ist, so daß, um den Staub zu gewinnen, noch ein besonderer Staubabscheider anzuschließen und. der Staub in den Gebrauchsbehälter zurückzuführen wäre. Die Anordnung gemäß der Erfindung bewirkt durch eine geschlossene Ringleitung, in die- das teils saugend, teils drückend wirkende Gebläse eingeschaltet ist, die Überführung des Staubgutes, die Aufwühlung desselben im unteren Teil des Bunkers und die * Rückführung der etwa noch geringe Staubteilchen enthaltenden Abluft ir den Bunker.Device for conveying dusty material by air from the storage container into the containers of use from bunkers When conveying powdery material Bunkering at the consumption points by means of suction air often shows the inconvenience, that the goods lying in the bunker are bad because of a certain tendency to bake slides, creating bridges and nests. One has therefore already means A special blower compressed air into the lower part of the bunker through built-in there Nozzles are blown into the material to ensure that it slides down. The invention exists now in the fact that one can achieve the overall effect of the promotion and whirling up with a unitary fan produces by its suction side in the usual Way to the dust collector of the container, but its pressure side to a LoosenerLUlgsclüse is connected in the lower part of the storage bunker. To this With the simplest means, wise one becomes very effective and not subject to any stagnation Conveying the dust, avoiding. Dust losses with the escaping Air achieved. It is already known per se, in the case of pure compressed air delivery to divide the compressed air flow by directing a partial flow into a loosening nozzle directs the other, larger one; used to promote itself. But here it is insufficient protection against the escape of dusty air from the container, so that this device is not sufficient for very fine-grained goods. Even the known ones Compressed air nozzles attached to the bottom of a silo to deliver its contents into a Emptying the container underneath does not take into account the fact that - That the air drawn off in the upper part of the container is still dusty, so that in order to collect the dust, a special dust collector should be connected and. the dust would be returned to the use container. The arrangement according to the invention caused by a closed ring line, into which - the partly sucking, partly depressing blower is switched on, the transfer of the dust, the commotion same in the lower part of the bunker and the * Return of the exhaust air, which still contains small dust particles, to the bunker.

Die Zeichnung stellt eine Ausführungsform des Erfindungsgedankens dar. Das im Vor= ratsbunker a enthaltene Vorratsgut wird durch die Saugdüse b ünd die För derleitun- b' in den Staubabscheider c übergeführt, von dvem es" durch eine daruntergebäute luftdicht(, Aüstragschleuse und ein Förderband in bekannter Weise der Verbrauchsstelle zugeführt wird. Der Unterdruck wird erzeugt durch das Gebläse e, das. die von Staub befreite Luft aus dem Staubabscheider c absaugt. .Die auf der Druckseite des Gebläses entcv;ichendc Luft wird nun, statt wie in üblicher Weis eins Freie; erfindungsgemäß in einen den unteren trichterförmigen Bunkerteil umschließenden Ringkanal f geleitet. Sie tritt dann durch geeignete Düsen g, vorzugsweise Rin, spaltdüsen, in das zu fördernde Gut ein. Der Druck in diesem Ringkanal kann dadurch geregelt werden, daß in der gegenüber der Eintrittsseite der Gebläseluft mündenden Seite ein Luftaustrittsrohr angeschlossen ist, das eine Regelklappe i o.dgl. enthält. Da unterhalb der Düse b an der tiefsten Stelle des Bunkers im allgemeinen noch Unterdruck herrscht, kann an dieser Stell,-ein Ansaugestutzen k für Frischluft angebracht sein, die dann bei ihrem Eintritt ebenfalls aufwühlend wirkt. Auf diese Weise wird ein Teil der im Kreislauf umgewälzten Förde rluft, der ins Freie abgeführt werden kann, durch Frischluft ergänzt. Die Regelklappe i kann in diesem Fall finit einer in diesem Fi-ischluftkanal eingebauten Regelklappe l zwangsläufig verbunden sein, um eine gemeinsrtme Regelung vorzunehmen.The drawing represents an embodiment of the inventive concept The stored goods contained in the storage bunker a are b ünd through the suction nozzle the conveying line b 'transferred into the dust separator c, from dvem it "through a Airtight built underneath (, Aüstragschleuse and a conveyor belt in a known manner is fed to the point of consumption. The vacuum is generated by the fan e, that sucks the air freed from dust from the dust separator c. .The on from the pressure side of the blower; instead of the usual air, air is now released one free; according to the invention in a lower funnel-shaped bunker part enclosing Ring channel f passed. It then occurs through suitable nozzles g, preferably Rin, slot nozzles into the material to be conveyed. The pressure in this ring channel can thereby be regulated that opens in the opposite to the inlet side of the blower air Side an air outlet pipe is connected, which a control flap i or the like. contains. Since below the nozzle b at the deepest point of the bunker there is generally still negative pressure prevails, an intake connection k for fresh air can be attached at this point, which then also has a disturbing effect when it occurs. This way becomes a Part of the air circulated in the circuit that can be discharged into the open, supplemented by fresh air. The control flap i can in this case finitely one in this Fi-ischluftkanal built-in control flap l inevitably be connected to a to undertake common regulation.

In die Saugleitung rd zwischen Saugpumpc-und Staubabscheider kann ein nicht dargetelltes Luftfilter eingeschaltet sein.In the suction line between suction pump and dust separator can an air filter, not shown, must be switched on.
