Abstract

The fireproof lining separates the drum outlets of a tubular rotary furnace from the cooling pipes. It comprises an interchangeable prefabricated component (9), with a steel frame (1) screwed into the outlet. Anchors are welded to the frame inside surface for tamping fireclay forming the outlet opening (10), with expansion joints (11) extending radially from the latter. At the collar edge this clay runs parallel to the outlet opening in the axial direction, while it converges inwards to the collar edge of the adjacent prefabricated component. The tapering chamber formed is tamped with fireproof material anchored to the drum, having expansion joints to the adjacent prefabricated parts.

Description

FEUERFESTE ZUSTELLUNG FÜR DIE AUSLASSE FIRE-RESISTANT SHELVING FOR THE OUTLETS

EINES DREHROHROFENS Die Erfindung betrifft eine feuerfeste Zustellung für die Auslässe der Trommel eines Drehrohrofens gegenüber den nachgeordneten Kühlrohren. A ROTATING TUBE FURNACE The invention relates to a refractory lining for the outlets of the drum of a rotary kiln opposite the downstream cooling tubes.

Der Ofenauslauf unterliegt verstärktem Verschleiß, so daß die wegen ihrer komplizierten Form meist monolithische Zustellung des öfteren repariert werden muss.The furnace outlet is subject to increased wear, so that the their complicated shape, mostly monolithic lining, are often repaired got to.

Die bekannten Zustellungen im Drehrohr-Auslaßbereich sind zusammenhängend. Es kann dann nur der jeweils unterste Bereich der Zustellung mit Reparaturmasse ausgestampft werden. Danach muss man warten, bis die Masse abgebunden hat, und dann wird die Ofentrommel weiter gedreht bis sich der nächste reparaturbedürftige Auslaß unten befindet usw.The known infeeds in the rotary kiln outlet area are interrelated. Only the lowest area of the infeed with repair compound can then be used be stamped out. Then you have to wait for the mass to set, and then the furnace drum is rotated further until the next outlet in need of repair is located located at the bottom, etc.

Zur Verminderung der dadurch bei der bekannten feuerfesten Zustellung der eingangs erwähnten Gattung bedingten Stillstandszeit wird erfindungsgemäß vorgeschlpn, die Ausbildung-der Zustellung als im ganzen auswechselbares Fertigbauteil,mit einem dem Auslaß kragenförmig angepaßten und darin verschraubten Stahlrahmen, auf dessen Innenflächen Anker geschweißt sind für feuerfeste Stampfmasse, welche die Auslaßöffnung bildet und radial zu dieser Dennfugen aufweist und im Bereich des Kragenrandes achsparallel zur Auslaßöffnung verläuft, keilförmig nach innen konvergierend zum Kragenrand des jeweils benachbarten Fertigbauteiles, wobei der Keilraum mit an der Trommel verankerter feuerfester Masse ausgestampft ist, mit Dehnungsfugen gegenüber den benachbarten Fertigbauteilen.To reduce the resulting in the known refractory lining of the genus mentioned at the beginning Downtime becomes according to the invention vorlpn, the training - the delivery as a completely replaceable prefabricated component, with a steel frame adapted to the outlet in the shape of a collar and screwed into it whose inner surfaces are welded anchors for refractory ramming mass, which the Forms outlet opening and has radial to this Dennfugen and in the area of The collar edge runs axially parallel to the outlet opening, converging inwardly in a wedge shape to the collar edge of the respective adjacent prefabricated component, with the wedge space with Refractory mass anchored to the drum is stamped out, with expansion joints compared to the neighboring prefabricated components.

Die Verschleißteile der erfindungsgemäßen Zustellung können nach Lösen der Verschraubung einfach vom Trommelinneren aus abgezogen und gegen ein neues Zustellelement ausgetauscht werden.The wearing parts of the lining according to the invention can after loosening The screw connection is simply removed from the inside of the drum and against a new feed element be replaced.
