Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei rotirenden Trommelofen, welche zu Brenn-, Rost- und Trockenzwecken gebraucht werden, findet eine erhebliche Wärmestrahlung von der Mantelfläche des Ofens aus statt, welche die Arbeit sehr erschwert und erhebliche Wärme Verluste im Gefolge hat. Um diesem Uebelstande einigermafsen zu begegnen, hat man versucht, den Ofenmantel zu kühlen, indem die Wandung desselben verdoppelt und von einem Wasserstrom durchflossen wurde. Durch diese Anordnung wird jedoch der Ofen sehr schwer, so dafs besondere Vorkehrungen gegen Durchbiegungen getroffen werden müssen. Aufserdem entstehen nicht unbeträchtliche Schwierigkeiten durch den Anschlufs des rotirenden Kühlmantels an die feststehenden Zu- und Ableitungen.With rotating drum kilns, which are used for firing, rusting and drying purposes there is considerable heat radiation from the outer surface of the furnace, which makes the work very difficult and results in considerable heat losses. To this To counter the inconvenience to some extent, attempts have been made to cool the furnace jacket by its wall was doubled and a stream of water flowed through it. However, this arrangement makes the furnace very difficult, so that special precautions must be taken against deflection. In addition, there are not inconsiderable difficulties when connecting the rotating cooling jacket to the fixed supply and discharge lines.

Vorliegende Erfindung besteht nun darin, dafs der Ofen mit einem feststehenden Kühlmantel umgeben wird. Dieser besteht aus einer doppelwandigen Trommel, in welcher eine Kühlflüssigkeit kreist. Bei dieser Anordnung wird das Gewicht der Ofentrommel in keiner Weise vergröfsert, vielmehr kann man durch Verringerung der Stärke des Ofenfutters eine wesentliche Gewichtsersparnifs herbeiführen. Die von dem feststehenden Kühlmantel aufgenommene Wärme kann unter Umständen zweckmäfsig weiter verwendet werden, so dafs erhebliche Wärmeersparnisse sich ergeben. The present invention consists in that the furnace is provided with a fixed cooling jacket is surrounded. This consists of a double-walled drum in which a coolant circulates. With this arrangement the weight of the furnace drum is not increased in any way, but by reducing the thickness of the furnace lining bring about a substantial weight saving. The ones from the fixed cooling jacket absorbed heat can be used appropriately under certain circumstances, so that considerable heat savings result.

Die beiliegende Zeichnung stellt in einem schematischen Längsschnitt eine derartige Ofenanordnung dar. Der in üblicher Weise gebaute, gelagerte und in Umdrehung versetzte Ofen α reicht mit seinem hinteren Ende in einen Fuchs. Der vor diesem liegende Theil des Ofens ist von einem hohlen Mantel d, der aus Blech hergestellt sein kann, umgeben. An den Unterstützungsstellen der Trommel ist dieser Mantel unterbrochen. Es wird beabsichtigt, diesen hohlen Mantel mit einer leicht siedenden Flüssigkeit zu füllen, beispielsweise mit flüssiger schwefliger Säure. Die entstehenden Dämpfe können dann durch eine Rohrleitung abgeführt und in geeigneter Weise verwerthet, beispielsweise in den neuerdings erprobten Kaltdampfmaschinen zur Krafterzeugung benutzt werden.The accompanying drawing shows a schematic longitudinal section of such a furnace arrangement. The furnace α , which is built, stored and set in rotation in the usual way, extends with its rear end into a fox. The part of the furnace in front of this is surrounded by a hollow jacket d, which can be made of sheet metal. This jacket is interrupted at the support points of the drum. It is intended to fill this hollow shell with a low-boiling liquid, for example liquid sulphurous acid. The resulting vapors can then be discharged through a pipeline and utilized in a suitable manner, for example used in the recently tried and tested cold steam machines to generate power.
