Description

wahenrtist Bei Walzenrosten zum Absieben von Schüttgut zeigt sich der Übelstand, daß einerseits nicht das gesamte Feinkorn aus dem Schüttgut ausgesiebt wird und daß andererseits in dem letzten Teil des Rostes Überkorn. mit dem Feingut abgesiebt wird. ' .wahenrtist with roller grates for sieving off bulk material shows the disadvantage that, on the one hand, not all of the fine grain is sifted out of the bulk material and that on the other hand, in the last part of the grate, oversize grain. with the fine material is screened. '.

Ein älterer, jedoch nicht vorveröffentlichter Vorschlag zur Vermeidung dieses Übelstandes besteht darin, daß in der Förderrichtung des Rostes außer der Spaltweite auch die Um-1aufzahl oder die -Exzentrizität der Scheibenwalzen oder beide abnehmen sollen. -Die vorliegende Erfindung beruht dagegen auf der Erkenntnis, daß es genügt, bei einem Walzen-. bzw. Scheibenwalzenrost mit durchweg gleicher Spaltweite und gleicher Hubwirkung der Walzen die Umlaufzahl der Walzen in der Förderrichtung abnehmen zu lassen.An older, but not prepublished, suggestion to avoid this this drawback is that in the conveying direction of the grate except the Gap width also the number of units or the eccentricity of the disc rollers or both should lose weight. -The present invention, however, is based on the knowledge that it is sufficient for a roller. or disc roller grate with consistently the same Gap width and the same lifting effect of the rollers, the number of revolutions of the rollers in the conveying direction to lose weight.

Auf der Zeichnung sind zwei Ausführungsbeispiele der Erfindung schematisch dargestellt.Two exemplary embodiments of the invention are shown schematically in the drawing shown.

Abb. i zeigt einen Scheibenwalzenrost zeit Kreisscheiben in. Seitenansicht und Abb. 2 in. Draufsicht.Fig. I shows a disc roller grate time circular discs in. Side view and Fig. 2 in. Top view.

Abb.3 zeigt einen Scheibenwalzenrost mit ellipsenförmigen Scheiben im senkrechten Längsschnitt und Abb. 4 eine Draufsicht zu Abb. 3.Fig.3 shows a disc roller grate with elliptical discs in vertical longitudinal section and Fig. 4 is a plan view of Fig. 3.

Die Scheibenwalzen i des Walzenrostes nach Abb. ; und 2 werden von den beiden Längswellen 2 aus mittels der Kegelräder 3 angetrieben, deren übersetzungsverhältnisnach dem Überlaufende des Rostes hin sich derart ändert, daß die Umdrehungsgeschwindigkeit der Scheibenwalzen stetig abnimmt.The disk rollers i of the roller grate according to Fig.; and 2 are from the two longitudinal shafts 2 driven by means of the bevel gears 3, their transmission ratio according to the overflow end of the grate changes so that the speed of rotation the disc rollers steadily decreases.

Bei dem Scheibenwalzenrost nach Abb.3 und 4 sind die Scheibenwalzen 4 mit Ellipsenscheiben durch , dazwischen eingeschaltete Scheibenwalzen 5 mit kreisrunden Scheiben in. Gruppen abgeteilt. Die Scheibenwalzen werden von den beiden Längswellen 6 aus mittels der Kegelräder 7 angetrieben, wobei das Übersetzungsverhältnis der Kegelräder innerhalb jeder Gruppe gleichbleibt, sich aber nach dem Überlaufende des Rostes hin derart ändert, daß die Scheib:enwalvengruppen mit abnehmender Geschwindigkeit angetrieben -werden.- Die Schreiben der Walzen 5 greifen zwischen die Scheiben der benachbarten Walzen 4, und der Durchmesser der Kreisscheiben der Scheibenwalzen 5 ist so bemessen, daß zwischen den Scheiben dieser Walze und den Scheiben der anliegenden Walzen 4 kein Längsspalt entsteht.In the case of the disc roller grate according to Figures 3 and 4, the disc rollers are 4 with elliptical disks through, interposed disk rollers 5 with circular ones Slices divided into groups. The disc rollers are driven by the two longitudinal shafts 6 driven from by means of the bevel gears 7, the transmission ratio of the Bevel gears remains the same within each group, but changes after the end of the overflow of the grate changes in such a way that the disk: enwalvengruppen with decreasing speed -be driven.- The letters of the rollers 5 grip between the discs of the adjacent rollers 4, and the diameter of the circular disks of the disk rollers 5 is dimensioned so that between the discs of this roller and the discs of the adjacent Rolls 4 no longitudinal gap is created.

Durch die Einrichtung nach der Erfindung wird ein Anstauen des Siebgutes mach dem Überlaufende hin, bewirkt, so daß das Feingut Zeit hat, zwischen die Scheiben zu gelangen, und andererseits das Durchtreten von Überkorn vermieden wird.By means of the device according to the invention, the material to be screened is dammed up put down the overflow, so that the fine material has time between the panes and, on the other hand, the passage of oversized grain is avoided.
