Description
Drehtrommel für Schmelzöfen Die Trommeln für drehbare Schmelzöfen bestehen aus einem geschlossenen Blechmantel, in dem das Ofenfutter eingesetzt ist. Brennt bei zu weit getriebener Abnutzung des Ofens das Ofenfutter an irgendeiner Stelle durch, so läuft das flüssige Material, da es nicht sofort einen Austritt nach außen linden kann, zwischen Futter und Mantelblech weiter. Es wird dann an irgendeiner anderen Stelle den Blechmantel durchbrechen. Ein solcher Durchbruch schwächt den Mantel und verursacht kostspielige Reparaturen. Man kann dieser Gefahr natürlich dadurch begegnen, daß man das Ofenfutter öfter erneuert. Diese Gegenmaßnahme ist aber sehr unwirtschaftlich, zumal der Abbrand des Ofenfutters bei abnehmender Wandstärke geringer wird.Rotary drum for melting furnaces The drums for rotating melting furnaces consist of a closed sheet metal jacket in which the furnace lining is inserted. If the oven is worn too far, it will burn the oven lining on anybody Pass through, so the liquid material runs, as it does not leak immediately can linden outwards, between the lining and the jacket sheet. It will then turn on break through the metal jacket at any other point. Such a breakthrough weakens the coat and causes costly repairs. One can risk this counter this, of course, by renewing the oven lining more often. This countermeasure but is very uneconomical, especially since the burning of the furnace lining with decreasing Wall thickness becomes smaller.
Um diese Nachteile zu vermeiden, wird die Ummantelung des Ofens nicht mehr als starre geschlossene Trommel. sondern als elastisches offenes Gerippe aus Profileisen oder Kesselblechstreifen ausgeführt. Beim Durchbrennen des Ofenfutters tritt das flüssige Material an der Durchbruchstelle aus, die durchbrochene Stelle ist sofort kenntlich und kann durch Drehen des Ofens nach oben gestellt werden, um ein weiteres Ausfließen zu vermeiden. Die durchbrochene Stelle des Futters kann evtl. von außen und innen ausgebessert werden. Da bei einem solchen Ofen das Durchbrennen des Futters sofort zu erkennen, der Austritt des flüssigen Materials durch Drehen des Ofens zu verhindern und die Durchbruchstelle wieder leicht auszubessern ist, so läßt sich ein solcher Ofen weit besser ausnutzen. Außerdem wird der frisch ausgemauerte Ofen in weit kürzerer Zeit austrocknen als ein Ofen mit geschlossenem Blechmantel.In order to avoid these disadvantages, the jacket of the furnace is not more than a rigid closed drum. but as an elastic open framework Profile iron or boiler plate strips executed. When the oven lining burns through the liquid material emerges at the breakthrough point, the perforated point is immediately recognizable and can be raised by turning the oven, to avoid further leakage. The perforated part of the lining can may need to be repaired from the outside and inside. As with such a furnace, the burning through of the feed can be seen immediately, the exit of the liquid material by turning of the furnace and the breakthrough is easy to repair again, in this way such a furnace can be used far better. In addition, the freshly bricked-up Dry out the oven in a much shorter time than an oven with a closed sheet metal jacket.
In den Abb. z und a ist eine beispielsweise Ausführungsform eines solchen Drehofens im Ouer- und Längsschnitt dargestellt. Es bedeutet a die Ausmauerung und b das aus Profileisen oder Kesselblechstreifen gebildete Gerippe.In Figs. Z and a, an example embodiment of such a rotary kiln is shown in cross-section and longitudinal section. It means a the brickwork and b the framework formed from profile iron or boiler sheet strips.
