Peter Meffert in Koblenz a. Rh. Mühlenaufgabevorrichtung mit ZerkleinerungseinrichtungPeter Meffert in Koblenz a. Rh. Mill feeding device with crushing device

Patentiert im Deutschen'Reiche vom 20. Januar 1932 abPatented in Germany on January 20, 1932

Die Erfindung bezieht sich auf eine Mühlenaufgabevorrichtung mit Zerkleinerungsvorrichtung, bestehend in einem von einer Prallwand umgebenen Schleuderteller.The invention relates to a mill feeding device with a comminuting device, consisting of a centrifugal plate surrounded by a baffle.

Das Neue besteht darin, daß unterhalb der Prallringebene ein mit dem Prallring gemeinsam angetriebenes Gebläserad vorgesehen ist, das einen" Luftstrom erzeugt, der den von dem Prallring niederfallenden Gutstrom kreuzt. Bei Anordnung mehrerer Gebläseräder übereinander sind unter dem Prallring stufenförmig zur Bildung von Gutstromkaskaden entsprechend jeder Gebläsestufe Rieselbleche angeordnet.The new thing is that below the level of the impact ring, a joint with the impact ring driven fan wheel is provided, which creates an "air flow that the of the falling material flow crosses the impact ring. When arranging several fan wheels one above the other are stepped under the impact ring to form crop flow cascades arranged according to each blower level trickle plates.

Nach der neuen Ausführung erreicht man, daß der feine blasfähige Pu<Jerstaub nicht mit in den Mahlgang gelangt und ihn somit nicht unnötig belastet. Der feine Kohlenstaub kann also nicht mehr für die groben, d. h. grießigen Kohlenteilchen als Polster wirken. Durch diesen Nachteil wurde bisher die Mahlung erschwert und verlangsamt.According to the new design, the fine blowable Pu'Jerstaub is not achieved gets into the grinding aisle and does not burden it unnecessarily. The fine coal dust so can no longer for the coarse, d. H. gritty coal particles as a cushion works. This disadvantage hitherto made grinding more difficult and slower.

Abb. 2 und 3 Einzelteile in vergrößertem Maßstabe.Fig. 2 and 3 individual parts on an enlarged scale.

Das Mahlgut wird aus dem Trichter in bekannter Weise durch den Wurfteller α gegen den feststehenden oder auch umlaufenden Prallring b geschleudert. Im letzteren Falle ist die Umdrehungsrichtung des Prallringes entgegengesetzt der Umdrehungsrichtung des Wurftellers, um die Prallwirkung zu erhöhen. Um die Prallwirkung weiter zu erhöhen, ist der Prallring möglichst nahe an dem Wurfteller angeordnet, außerdem ist er, um die Prallfläche zu vergrößern, mit Rippen versehen, die so gesetzt sind, daß das Mahlgut, welches tangential vom Wurfteller abfliegt, senkrecht gegen die Rippenwandung geschleudert wird, wie Abb. 3 zeigt. Des weiteren sind die Rippen etwas schräg nach unten gesetzt, um den Anprall des parabelförmig abfallenden Gutes zu verstärken, wie Abb. 2 zeigt.The ground material is thrown from the funnel in a known manner through the throwing plate α against the stationary or rotating baffle ring b. In the latter case, the direction of rotation of the impact ring is opposite to the direction of rotation of the throwing plate in order to increase the impact effect. In order to further increase the impact effect, the impact ring is arranged as close as possible to the throwing plate, and in order to increase the impact surface, it is provided with ribs that are set so that the grist, which flies tangentially from the throwing plate, perpendicularly against the rib wall is thrown, as Fig. 3 shows. Furthermore, the ribs are set slightly downwards to increase the impact of the parabolic sloping material, as Fig. 2 shows.

Bei der Erfindung soll möglichst viel Kohle durch den Anprall, d. h. durch die Schleuderkraft, zerkleinert werden. Das Mahlgut fällt kaskadenartig über die Jalousieringe d und wird beim Passieren der Kaskaden von dem Luftstrom erfaßt, welcher den Kohlenstaub mit in den Ring e reißt. Hier verringert sich die Luftgeschwindigkeit, wodurch der grießige Staub nach unten absinkt und mit der körnigen Kohle an dem Umfang des inneren Mantels f dem Mahlring und den Mahlwalzen der Mühle zufällt. Das zu mahlende grießige Gut wird so den Mahlflächen der Mahlkörper unmittelbar zugeführt.In the invention, as much coal as possible is to be crushed by the impact, ie by the centrifugal force. The ground material falls cascade-like over the louvre rings d and is caught by the air flow as it passes through the cascades, which pulls the coal dust with it into the ring e . Here the air speed is reduced, as a result of which the gritty dust sinks down and falls with the granular coal on the circumference of the inner jacket f to the grinding ring and the grinding rollers of the mill. The coarse material to be ground is thus fed directly to the grinding surfaces of the grinding media.

Um den durch das Gebläse^ erzeugten Luftstrom zu verstärken und den Kaskaden die Luft zuzuleiten, ist das mehrstufige Schaufelrad h vorgesehen. Die Schaufelbleche der ein-In order to increase the air flow generated by the fan ^ and to feed the air to the cascades, the multi-stage impeller h is provided. The blade plates of the

zelnen Luftzuführungsringe dienen gleichzeitig als Distanzbleche zwischen letzteren. Durch geeignete Speichenanordnung ist der Prallring b mit dem mehrstufigen Schaufel-S rad h verbunden. Das Schaufelrad kann auch durch die Welle der Hauptmühle angetrieben werden.Individual air supply rings also serve as spacer plates between the latter. The impact ring b is connected to the multi-stage blade wheel h by means of a suitable spoke arrangement. The paddle wheel can also be driven by the shaft of the main mill.

Spirally wound flat iron rings is provided in order to divert the gritty dust downwards, while the air with the powder dust is sucked in a known manner by the fan into the cyclone k , from which it is drawn off through sluices or the like.
