Description

Ofen mit Schubrost Das Hauptpatent betrifft einen Ofen zum Brennen von Zement und ähnlichen Stoffen auf einem Schubrost. Der Zweck eines solchen Rostes besteht darin, ein Überbrennen des Gutes oder einzelner Teile davon zu verhindern. Die Erfindung hat den Zweck, das Anwendungsgebiet des Ofens nachdem Hauptpatent zu erweitern, und zwar soll ein solcher Ofen für das Brennen von Ton zu Schamotte verwendet werden.Furnace with sliding grate The main patent relates to a furnace for burning of cement and similar materials on a sliding grate. The purpose of such a grate consists in preventing overburning of the goods or individual parts thereof. The invention has the purpose of the field of application of the furnace according to the main patent to expand, namely such a furnace for firing clay to fireclay be used.

Der zur Herstellung von Schamotte dienende Rohton erleidet beim Brande, bei dem die natürliche Feuchtigkeit und das Kristallwasser ausgetrieben wird, erhebliche Formänderungen, ohne daß er eine größere Fließfähigkeit erhält. Er verwandelt sich vielmehr beim Brennen in harte Stücke von verschiedener Größe. In den bisher für das Brennen benutzten Schacht-, Kammer- oder Tunnelöfen entstanden hierdurch große Schwierigkeiten, weil große Stücke sich festklemmten, kleine Teilchen hingegen den Ofen verstopften und den Durchgang der Feuergase verhinderten.The raw clay used to make chamotte suffers from fire, in which the natural moisture and crystal water is expelled, considerable Changes in shape without giving it greater fluidity. He's transforming rather when burning into hard pieces of various sizes. In the so far for The shaft, chamber or tunnel furnaces used for firing were created as a result of this large ones Difficulties because large pieces got stuck while small particles got stuck Clogged the furnace and prevented the passage of the gases from the fire.

Diese Schwierigkeiten werden vermieden, wenn erfindungsgemäß ein Ofen mit Schubrost benutzt wird. Der Schubrost hält den Ton während des Brandes in dauernder Bewegung und verhindert so die Bildung großer Stücke.These difficulties are avoided when inventing a furnace is used with a sliding grate. The sliding grate keeps the clay in place during the fire Movement, thus preventing large pieces from forming.

Zur Beschickung eines solchen Ofens wird der grubenfeuchte Rohton zweckmäßig auf einem Kollergang, einem Tonhobel oder einer Knetschnecke aufbereitet und mit dem für den Brand erforderlichen Brennstoff vermischt.The raw clay, which is moist in the pit, is used to load such a furnace expediently prepared on a pan mill, a clay plane or a kneading screw and mixed with the fuel required for the fire.

Je nach der Art des Rohtones wird dieser bisweilen vorteilhaft auch trocken aufbereitet durch Mahlen und Mischen verschiedener Tonsorten. Dem so erzeugten Mehl wird dann der Brennstoff beigegeben und das Gemscb angefeuchtet, um es besser aufgeben zu können.Depending on the type of raw clay, this is sometimes also beneficial prepared dry by grinding and mixing different types of clay. The one created in this way Flour is then added to the fuel and the Gemscb moistened to make it better to be able to give up.

Ein solches Mischen kann auch vorgenommen werden, wenn. ein zwar hochfeuerfester, aber beim Brennen sehr dicht und spröde werdender Ton zur Verfügung steht, der vor dem Brande gemagert werden muß, um eine brauchbare Schamotte zu ergeben. Auch zur Aufbesserung des Tonerdegehaltes und zur Erhöhung des Schmelzpunktes kann ein solches Mischen stattfinden, wobei dann vorteilhaft ein Zusatz von Kaolin erfolgt.Such mixing can also be done, if. a highly fireproof, but when burning there is a very dense and brittle tone available that is in front of must be leaned to the fire in order to produce a usable chamotte. Also for This can be done by improving the alumina content and increasing the melting point Mixing take place, in which case kaolin is advantageously added.
