Description
Fördervorrichtung für pulverförmiges Gut. Es sind Fördervorrichtungen -für pulverförmiges Gut bekannt, bei denen das Gut in eine vom Fördergehäuse seitlich abzweigende Leitung durch -eine Förderschnecke, die einerseits an der Stirnwand des Fördergehäuses und andererseits in der Wand der abzweigenden Leitung gelagert ist, und durch ein aus Düsen austretendes flüssiges -oder gasförmiges Fördermittel gefördert wird.- Die Erfindung erbringt aber eine neue Kombination insofern, als das flüssige oder gasförmige Fördermittel in die Masse des aus dem Schneckengehäuse austretenden gepreßten Gutes gleichzeitig durch den hinter der Förderschnecke angeordneten Düsenring und aus dem unter den Druck des Fördermittels gesetzten Schneckenlager in der Wand der abzweigenden Leitung zugeführt wird. Durch diese Kombination an sich schon bekannter Elemente wird eine neue Wirkung erzielt, die in dem Zusammenarbei= ten der beiden Fördermittelzuführungen zur Durchsetzung des von der Förderschnecke zusammengepreßten pulverförmigen Gutes und dessen Ablenkung in die seitliche Förderleitung zu suchen ist. Gleichzeitig wird die Nebenwirkung erreicht, daß die Zuführung des flüssigen oder gasförmigen Fördermittels über das Schneckenlager in der Abzweigleitung dieses Lager in an sich bekannter Weise vor Eintritt von Staub schützt.Conveyor device for powdery material. They are conveyors -for powdery material known, in which the material in one of the conveyor housing laterally branching line through -a screw conveyor on the one hand on the front wall the conveyor housing and on the other hand stored in the wall of the branching line is, and by a liquid or gaseous conveying means emerging from nozzles is funded.- The invention, however, provides a new combination in that the liquid or gaseous conveying medium in the mass of the from the screw housing exiting pressed material at the same time by the arranged behind the screw conveyor Nozzle ring and from the screw bearing placed under the pressure of the conveyor is fed in the wall of the branching line. Through this combination elements that are already known, a new effect is achieved, which in the cooperation = ten of the two conveyor feeds to enforce the from the screw conveyor compressed powdery material and its deflection into the lateral conveying line to look for. At the same time, the side effect is achieved that the supply of the liquid or gaseous conveying medium via the screw bearing in the branch line this camp protects in a manner known per se from the entry of dust.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist schematisch auf der Zeichnung dargestellt.An exemplary embodiment of the subject matter of the invention is schematic shown on the drawing.
Abb. i zeigt einen Längsschnitt durch die ganze Einrichtung.Fig. I shows a longitudinal section through the entire facility.
Abb.2 zeigt den Düsenring in vergrößertem Maßstabe.Fig.2 shows the nozzle ring on an enlarged scale.
Die Fördervorrichtung besteht aus dem Gehäuse a, in welches das pulverförmige Gut durch den Trichter b eingebracht wird, und aus einer Schnecke c, die auf eine Welle d aufgesetzt ist. Die Welle d wird von außen her angetrieben.The conveyor consists of the housing a, in which the powdery Well is introduced through the funnel b, and from a screw c, which on a Shaft d is attached. The shaft d is driven from the outside.
Durch die Schnecke wird das pulverförmige Gut vom Trichter b nach dem Austragende bewegt, wobei es gleichzeitig in bekannter Weise einem zunehmenden Druck ausgesetzt wird; indem z. B. sich das Gehäuse a entsprechend verjüngt. Unmittelbar hinter der Schnecke ist der Düsenringe mit dem ringsumlaufenden ]Kanal/ angebracht, an welchen sich die einzelnen Düsen g anschließen. Diese Düsen g sind gleichmäßig über den ganzen Umfang des Mundstückes der Förderleitung a verteilt, so daß das pulverförmige Gut von allen Seiten von dem flüssigen oder gasförmigen Fördermittel erfaßt und mit diesem innig vermischt wird.The pulverulent material is moved from the hopper b by the screw the discharger moves, at the same time it is increasing in a known manner Exposure to pressure; by z. B. the housing a tapers accordingly. Direct behind the screw is the nozzle ring with the surrounding] channel /, to which the individual nozzles g connect. These nozzles g are uniform distributed over the entire circumference of the mouthpiece of the delivery line a, so that the powdery material from all sides by the liquid or gaseous conveying means is detected and intimately mixed with this.
Die Ausflußöhnungen der Düsen g sind, um gleichzeitig die Förderwirkung der Vorrichtung zu unterstützen, in bekannter Weise so gerichtet, daß ihre Achsen sämtlich auf einem Punkt der Achse der Förderschnecke zusammentreffen. Unmittelbar hinter dem Düsenring zweigt die Förderleitung h von dem Gehäuse a seitlich ab.The Ausflußöhnungen the nozzles g are to simultaneously the conveying effect to support the device, directed in a known manner so that their axes all meet at one point on the axis of the screw conveyor. Direct behind the nozzle ring, the delivery line h branches off laterally from the housing a.
Die den Durchtritt der Achse d hinter dem Düsenring e vermittelnde Stopfbüchse l steht so unter Luft- oder Wasserdruck, daß Luft oder Wasser nur nach innen übertritt, wo es mit dem aus dem Düsenring austretenden Gut zusammentrifft.The mediating the passage of the axis d behind the nozzle ring e Stuffing box l is so under air or water pressure that air or water only after inside where it meets the material emerging from the nozzle ring.
