Verfahren zum Anordnen von Einbauten in Gutführungsrohre von Wärmebehandlungseinrichtungen für pulvriges bis körniges, rieselfähiges, gegebenenfalls angeschlämmtes GutMethod for arranging internals in material pipes of heat treatment devices for powdery products to granular, free-flowing, possibly slurried material

Die Erfindung richtet sich auf ein Verfahren zum Anordnen von Einbauten in um eine Achse drehbare, von außen beheiz- und kühlbare Gutführungsröhre von Wärmebehandlungseinrichtungen für pulvriges bis körniges, rieseifähiges, gegebenenfalls angeschlämmtes Gut.The invention is directed to a method for arranging internals in rotatable about an axis of Outside heatable and coolable material guiding tubes from heat treatment facilities For powdery to granular, gigantic, possibly slurried goods.

Drehrohre oder Rohre von Drehtrommeln mit Rohrbündeln mit indirekter Beheizung zum Wärmebehandeln von pulvrigem bis stückigem, rieselfähigem Gut weisen recht häufig solch geringen Durchmesser auf, daß man zum Einbringen der Einbauten und zum Befestigen derselben nicht mehr hineinkriechen kann. In solchen Fällen wurden bisher Halbrohre verwendet, die nach dem Einschweißen oder Annieten der Einbauten zusammengeschweißt wurden. Diese Verfahrensweise ist sehr aufwendig und bereitet wegen der fertigungstechnischen Toleranzen der Halbrohre oft Schwierigkeiten. Von besonderem Nachteil dabei ist, daß der Verschleiß der Einbauten im Rohrinneren nurRotary tubes or tubes of rotary drums with tube bundles with indirect heating for the heat treatment of powdery products to lumpy, free-flowing material quite often have such a small diameter that it is necessary to introduce the fixtures and fixtures can no longer crawl into them. In such cases were So far, half-pipes have been used, which were welded together after the fixtures were welded in or riveted on. This procedure is very complex and prepares because of the manufacturing tolerances of the half-tubes often difficulties. A particular disadvantage here is that the internals only wear out

schlecht kontrollierbar ist und daß vor allem schadhafte Teile ohne Aufschneiden des Rohres nicht austauschbar sind. Auch ist es nicht möglich, für die aufeinanderfolgende Wärmebehandlung verschiedener Güter die Einrichtung hinsichtlich der Einbauten in den Gutführungsrohren die dem jeweiligen zu behandelnden Gut eigenen Bedürfnisse anzupassen.is difficult to control and, above all, damaged parts cannot be replaced without cutting open the pipe are. It is also not possible for the successive heat treatment to be different Goods the device with regard to the fixtures in the crop guide pipes to be treated in each case Adapt well to your own needs.

Die Aufgabe besteht darin, ein Verfahren anzugeben, mit dem sich Einbauten in Gutführungsrohren von Wärmebehandlungseinrichtungen derart anordnen lassen, daß die Montage schnell und einfach vor sich geht, daß zur Verbesserung des wärmeübergangs enge Toleranzen eingehalten werden können und daß die Einbauten leicht austauschbar sind.The task consists in specifying a method with which internals in material guide pipes of heat treatment facilities Can be arranged in such a way that the assembly is quick and easy, that tight tolerances to improve the heat transfer can be complied with and that the internals are easily exchangeable.

Die Aufgabe wird dadurch gelöst, daß die Einbauten je Rohr als Einheit vorgefertigt und als solche in das Rohr eingebracht und austauschbar befestigt werden. The object is achieved in that the internals per pipe prefabricated as a unit and as such in the tube can be inserted and fastened interchangeably.

Dadurch wird erreicht, daß in Umfangsrichtung völlig geschlossene Rohre verwendet werden können. Die Einbaueinheit läßt sich, gegebenenfalls unter Zuhilfenahme von Vorrichtungen ,aus Einzelteilen zusammenschweißen, -nieten oder -schrauben. Sie wird vorzugsweise an ihren Enden mit Befestigungselementen versehen und ist ohne Schwierigkeiten in das Gutführungsrohr einschiebbar und daran befestigbar.This ensures that completely in the circumferential direction closed tubes can be used. The installation unit can be, if necessary with the help of of devices, welding, riveting or screwing together from individual parts. She will preferably provided with fastening elements at their ends and is easily inserted into the crop guide tube can be pushed in and attached to it.

Es hat sich überraschenderweise gezeigt, daß auch bei langen Rohren so enge Toleranzen eingehalten werden können, daß die Einbauten, die beispielsweise aus Wendeln und Leisten bestehen, mit der Innenwandung des Rohres nahezu dicht abschließen. Dies istIt has surprisingly been found that also with long pipes so tight tolerances can be maintained that the internals, for example from Coils and strips exist, close almost tightly with the inner wall of the pipe. This is besonders wesentlich, damit bei indirekt von außenespecially essential, so with indirect from the outside beheiz- oder kühlbaren Rohren das Gut auf der Rohrwandung bei der Drehbewegung des Rohres nicht schleift, sondern durch die Einbauten mit hochgenommen wird und erst bei einem gewissen Winkel die darunterliegende Gutschichtheatable or coolable pipes the material on the pipe wall does not grind when the pipe rotates, but is taken up by the fixtures and only at the underlying layer of material at a certain angle überrieselt. Dadurch wird der Wärmeübergang erheblich verbessert, und der Verschleiß an der Rohrwand sinkt auf ein Minimum.trickled over. This increases the heat transfer considerably improved, and the wear on the pipe wall is reduced to a minimum.

Bei der Vorfertigung einer Einbaueinheit, die beispielsweise aus Leisten und Wendeln aufgebaut ist, ist es zweckmäßig, die Leisten und/oder Wendeln mit Passschlitzen zu versehen und mittels dieser Schlitze zusammenzustecken. Sofern eine genügend feste Klemmwirkung vorhanden ist., ist ein Verschweißen der Teile unter Umständen nicht einmal erforderlich.When prefabricating a built-in unit, which is made up of strips and coils, for example, it is expedient to provide the strips and / or coils with fitting slots and by means of these slots put together. If there is a sufficiently firm clamping effect, the parts must be welded may not even be necessary.
