Description
Abstreicherkärnme für Scheibenwalzenroste Bei Scheibenwalzenrosten zum Absieben von Schüttgut sind die in den Spaltei- zwischen den Scheiben angeordneten Abstreicher aus Stahl hergestellt worden. Dabei zeigte sich der übelstand, daß die Scheiben sich am Umfang nach längerer Betriebszeit durch die Reibung an den Abstreichzähnen stark abnutzen. Man ist daher für die Ausführung der Abstreicher zu anderen Baustoffen- Schmiedeeisen, auch in Form von Schwarzblech, Graueisen, Temperguß .oder Bronze - übsrgegangen. -Demgegenüber besteht die Erfindung darin, daß die Abstreicherkämme aus Holz oder Hartgummi hergestellt werden, wobei bei der Verwendung von Holz die Fasern in der Richtung der Abstreichzähne verlaufen müssen. Diese Baustoffe besitzen eine genügende Zähigkeit, daneben aber auch eine geringe federnde Nachgiebigkeit. Diese .letztere Eigenschaft haben die bisher für Abstreicher verwandten Baustoffe nicht.Scraper arms for disc roller grates For disc roller grates for sieving off bulk material, those arranged in the gaps between the panes are Scrapers made of steel. It showed the evil that the Discs themselves on the circumference after a long period of operation due to the friction on the scraper teeth wear out heavily. It is therefore necessary to carry out the scrapers for other building materials Wrought iron, also in the form of black plate, gray iron, malleable cast iron. Or bronze - passed over. -In contrast, the invention consists in that the scraper combs made of wood or hard rubber, with the use of wood the Fibers must run in the direction of the scraper teeth. Own these building materials a sufficient toughness, but also a low resilience. The building materials previously used for scrapers have this latter property not.
Auf der Zeichnung sind mehrere Ausführungsbeispiele von Abstreichern nach der Erfindung dargestellt. Abb. i -bis ¢ zeigen eine für die Herstellung.aus Holz geeignete Abstreicherform und Abb.5 und- 6 einen durch Pressen oder Gießen aus Hartgummi herstellbaren Abstreicherkamm. -Die Abstreicher nach der Erfindung haben gegenüber den Abstreichern aus den bisher verwandten Baustoffen den Vorteil, daß sie sich bei geringen Ungenauigkeiten in der Form oder Anordnung gegenüber den Scheiben der Rostwalzen schnell anpassen, ohne die Scheiben anzugreifen, dann aber eine gute Widerstandsfähigkeit im Betrieb, zeigen. Ein weiterer Vorteil liegt darin, daß der Baustoff leicht bearbeitbar ist, so daß, insbesondere bei Herstellung .der Abstreicher aus Holz, im Bedarfsfall ein Ersatz an Ort und Stelle hergestellt werden kann.Several embodiments of scrapers are shown in the drawing shown according to the invention. Fig.i -bis ¢ show one for making. From A scraper shape suitable for wood and Fig. 5 and 6 one by pressing or pouring Scraper comb that can be made from hard rubber. -The scrapers according to the invention have the advantage over scrapers made from previously used building materials, that they are with minor inaccuracies in the form or arrangement compared to the Quickly adjust the slices of the grate rollers without attacking the slices, but then show good resistance in operation. Another advantage is that the building material is easy to process, so that, especially when manufacturing .der Scraper made of wood, if necessary a replacement can be made on the spot can.
