Die Erfindung betrifft eine pneumatische Fördervorrichtung für Getreide und andere körnige Materialien, bei welcher die Mischung von Luft und Korn im Saugrohre eine Drehbewegung erhält, um zu verhindern, dafs das Getreide sich in wagerechten Theilen des Saugrohres ablagere.The invention relates to a pneumatic conveying device for grain and others granular materials in which the mixture of air and grain in the suction pipe causes a rotary motion in order to prevent the grain from being deposited in horizontal parts of the suction pipe.
Wenn diese Drehbewegung, wie bekannt, durch in die Saugleitung eingebaute Schneckengänge erzielt wird, so entsteht eine starke Reibung der Körner an den Schneckengängen, und dadurch wird die Leistungsfähigkeit der Vorrichtung verringert.When this rotary movement, as is known, by worm flights built into the suction line is achieved, there is strong friction between the grains and the worm threads, and this reduces the performance of the device.
Die Erfindung besteht nun darin, dafs die ringförmige, das Ansaugen des Getreides bewirkende Saugdüse mit geneigten Rillen für den alleinigen Durchgang der Luft versehen ist, derart, dafs das Getreide, welches sich mit der aus den geneigten Rillen austretenden Luft mischt, an der Drehbewegung des Luftstromes theilnimmt, ohne sich an den schrägen Flächen zu reiben.The invention now consists in the fact that the ring-shaped suction effect of the grain Suction nozzle is provided with inclined grooves for the sole passage of air, so that the grain, which is with which mixes the air emerging from the inclined grooves, due to the rotary motion of the air flow participates without rubbing against the sloping surfaces.
Fig. ι der beiliegenden Zeichnung veranschaulicht die Gesammtanlage der auf einem mit Getreide beladenen Schiffe aufgestellten pneumatischen Fördervorrichtung.Fig. Ι the accompanying drawing illustrates the entire system of the pneumatic conveying device set up on a ship loaded with grain.
Fig. 2 ist ein senkrechter Schnitt des ringförmigen Injectors undFig. 2 is a vertical section of the annular injector and
Fig. 3 ein Schnitt nach der Linie A-B der Fig. 2. FIG. 3 shows a section along the line AB in FIG. 2.
Die pneumatische Fördervorrichtung zeigt zwei parallele Rohre 1 und 4, deren untere gegen einander gebogene Enden durch eine Kapsel 2 und ein an dieser sitzendes Ringstück 3 verbunden sind. Die innere Wandung des Ringstückes 3 hat nahezu Zylindrische oder, wie in Fig. 2 dargestellt, hyperboloidische Form. Das Ringstück reicht bis in die Nähe des Bodens 5 der Kapsel 2. Der Boden 5 nimmt in einer Kreisöffnung eine Saugdüse 6 auf, deren Aufsenseite kegelförmig verläuft und mit etwas Spielraum in die untere Oeffnung des Ringstückes 3 hineinragt.The pneumatic conveying device shows two parallel tubes 1 and 4, the lower one ends bent towards one another through a capsule 2 and a ring piece seated on this 3 are connected. The inner wall of the ring piece 3 is almost cylindrical or, as shown in Fig. 2, hyperboloidal shape. The ring piece extends into the vicinity of the base 5 of the capsule 2. The base 5 accommodates a suction nozzle 6 in a circular opening on, the outside of which is conical and with some clearance in the lower opening of the ring piece 3 protrudes.
Die kegelförmige Aufsenseite der Düse 6 ist mit schrägen Rillen 7 versehen, welche den durch die Rillen eintretenden Luftstrahlen eine solche Richtung geben, dafs sie in einer hyperboloidischen Mantelfläche verlaufen, ohne dafs sie sich treffen.The conical outside of the nozzle 6 is provided with inclined grooves 7, which the air jets entering through the grooves give such a direction that they are in a hyperboloidal direction Outer surface run without meeting.
Die Theile 2 und 6 einerseits sowie die Theile 3 und 4 andererseits sind mittelst Bolzen so mit einander verbunden, dafs der Abstand zwischen der Düse 6 und dem Ringstück 3 leicht geregelt werden kann.Parts 2 and 6, on the one hand, and parts 3 and 4, on the other hand, are by means of bolts so connected that the distance between the nozzle 6 and the ring piece 3 can be easily regulated.
Die durch einen Ventilator erzeugte Prefsluft strömt in der Pfeilrichtung durch das biegsame Rohr 8 zum Injector, worauf das Getreide- und Luftgemisch durch die Steigeleitung 14 weiter zur Entladestelle befördert wird. An der Stelle 13 kann noch ein Hülfsinjector angeordnet sein.The compressed air generated by a fan flows through the in the direction of the arrow flexible pipe 8 to the injector, whereupon the grain and air mixture through the riser pipe 14 is transported further to the unloading point. An auxiliary injector can also be used at position 13 be arranged.
Mit Hülfe eines an dem Ringe 11 befestigten Seiles 10 wird die Fördervorrichtung so aufgehängt, dafs die Saugdüse 6 theilweise in das Getreide hineinragt.With the help of one attached to the ring 11 Rope 10, the conveyor device is suspended in such a way that the suction nozzle 6 partially enters the Grain protrudes.
Infolge der in der Saugdüse 6 entstehenden Druckverminderung wird an dieser Stelle das Getreide und die Aufsenluft angesaugt und, indem sie sich mit der aus den Rillen 7 austretenden-Luft mischen, treten sie in dasAs a result of the pressure reduction occurring in the suction nozzle 6, the Grain and the outside air sucked in and by being with the air emerging from the grooves 7 mix, step into that
