Description

Schaufel zur Einmauerung in das Mauerwerk von Drehöfen Bei Drehofenausmauerungen sind des ;öfteren vorspringende Schaufeln oder Wendeleisten angewendet worden zu dem Zweck, die Beschickung umzuwenden oder durchzurühren, um einen schnelleren Wärmeübergang von den heißen Gasen auf das Gut zu erreichen. Versuche in dieser Hinsicht scheiterten, weil die vorspringenden Teile der Ausmauerung über kurz oder lang wegplatzten. Denn insbesondere bei Anwendung höherer Temperaturen führte der Temperaturunterschied zwischen dem in das Ofeninnere hineinragenden, der vollen Hitze ausgesetzten Teil und dem eingemauerten Teil des Steines zu inneren Spannungen, die der hitzebeständige Stoff, Schamotte oder ein ähnlicher hitzebeständiger Baustoff, nicht vertrug.Shovel for brickwork in the brickwork of rotary kilns often protruding blades or turning strips have been used to the purpose of turning or stirring the charge in order to achieve faster heat transfer from the hot gases to reach the estate. Attempts in this regard failed because sooner or later the protruding parts of the brickwork burst away. Because The temperature difference resulted in particular when using higher temperatures between the part that protrudes into the interior of the oven and is exposed to full heat and the walled-in part of the stone to internal stresses that the heat-resistant Fabric, chamotte or a similar heat-resistant building material, not tolerated.

Während nach dem Hauptpatent 61o 8I4 im vorspringenden Stein eine odex mehrere Aushöhlungen an der der Drehrichtung @entgegengesetzten. Seite vorgesehen sind, können nach der Erfindung diese Aushöhlungen, die bis hinter die innere Ausmauerungsoberfläche des Drehofens greifen, auch an anderen Seiten der Schaufeln, die der Diehrichtmig nicht entgegengesetzt sind, angebracht werden. Hierdurch wird eine Durchwärmung des Steines auch im eingemauerten Teil. ermöglicht, weil die heißen Gase nicht nur den vorspringenden Teil, sondern auch das Innere des Steines erhitzen. Der Temp;eraturgegensatz im Stein selbst und -damit die inneren Spannungen werden hierdurch stark verringert und em Abplatzen verhütet.While according to the main patent 61o 8I4 in the protruding stone odex several cavities on the opposite of the direction of rotation @. Side provided are, according to the invention, these cavities that extend beyond the inner lining surface of the rotary kiln, also on other sides of the blades, which the Diehrichtmig are not opposite to each other. This creates a warming through of the stone also in the walled-in part. made possible because the hot gases not only heat the protruding part but also the inside of the stone. The temp; erature contrast In the stone itself and thus the internal tensions are greatly reduced and prevents chipping.
