Befestigung für Laufringe bei Drehrohröfen, Drehtromineln o. dgl.Attachment for race rings in rotary kilns, Rotating tumblers or the like
Die Erfindung befaßt sich mit der Befestigung für Laufringe· bei Drehrohröfen, Drehtrommeln O0 dglo Bei einer Befestigung der Laufringe auf dem Drehrohr oder auf der Drehtrommel, bei der der Laufring nicht starr mit dem Rohrmantel verbunden ist, muß auf die Möglichkeit einer Relativ-Bewegung zwischen dem Rohrmantel und dem Laufring Rücksicht genommen werden, da sich der Rohrmantel infolge der Wärmeeinwirkung ausdehnt und bei Abkühlung wieder zusammenzieht. Für derartige Laufringbefestigungen sind bereits eine größere Anzahl von Vorschlägen gemacht wordeneThe invention is concerned with the fastening for races in rotary kilns, rotary drums O 0 dglo When the races are fastened on the rotary tube or on the rotary drum, in which the race is not rigidly connected to the tube jacket, the possibility of relative movement must be ensured Consideration must be given between the pipe jacket and the race, as the pipe jacket expands as a result of the action of heat and contracts again when it cools down. A large number of proposals have already been made for such raceway fastenings
Die Erfindung hat sich die Aufgabe gestellt, eine möglichst einfache und billige Befestigungsart vorzuschlagen. Die Erfindung besteht darin, daß der Laufring mit radialem Spiel gegenüber dem Trommelmantel zwischen Führungsplatten geführt ist, die auf parallel zur Rohrachse und in Umfangsrichtung des Rohrmantels, im Abstand nebeneinander liegenden Tragplätten aufgeschweißt sind, und die Verbindung zwischen dem Laufringfuß und den Führungsplatten durch eine Vielzahl von am Umfang in Abständen hintereinander vorgesehenen, radial gerichteten BoIzea erfolgt, wobei jeder Bolzen in je zur Hälfte im Lauf ringfuß und in den Führungsplatten angebrachten Bohrungen eingesetzt und einseitig an den Führungsplatten angeschweißt ist. Diese Befestigungsart bietet den Vorteil, daß die Verbindung nach erfolgtem Ausrichten und Einlaufen des Drehrohrofens auf der Baustelle vorgenommen werden kann.The object of the invention is to propose the simplest and cheapest possible type of fastening. The invention consists in that the race with radial play relative to the drum shell between guide plates is guided, which are parallel to the pipe axis and in the circumferential direction of the pipe jacket, at a distance from one another lying support plates are welded, and the connection between the race foot and the guide plates a plurality of radially directed BoIzea provided at intervals one behind the other on the circumference, each Half of the bolts are in the ring base and half in the guide plates attached holes and is welded on one side to the guide plates. This type of attachment offers the advantage that the connection is made after alignment and running in of the rotary kiln on the construction site can be made.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown in one embodiment.
Abb. 1 ist ein Schnitt nach Linie A-B der Abb, 2„ Abb» 2 ist ein Schnitt nach Linie C-D der Abb. 3.Fig. 1 is a section along line A-B of Fig. 2 " Fig »2 is a section along line C-D of Fig. 3.
Abb. 3 zeigt die erfindungsgeaiäße Befestigungsart im Grundriß.Fig. 3 shows the type of fastening according to the invention in plan.
Auf der Drehrohrtrommel 1 sind in ümfangsrichtung der Trommel im Abstand nebeneinander die Tragplatten 2 aufgeschweißt. Auf diesen wiederum sind die Führungsplatten 3 durch Schweißung befestigt. Zwischen den einander gegenüberliegenden Führungsplatten 3 ist der Laufring 4 mit radialem Spiel gegenüber dem Rohrmantel 1 bzw. den Tragplatten 2 geführt. Die Verbindung des Laufringfußes mit den Führungsplatten 3 erfolgt durch die Bolzen 5» die radial zum Ofenrohr verlaufen. Die Bolzen 5 befinden sich in Bohrungen, die zur Hälfte im Laufringfuß und zur Hälfte in den Führungsplatten 3 vorgesehen sind. Die Bolzen 5 sind einseitig an ihrem oberen Ende mit den Führungsplatten 3 verschweißt. Bei einer Ausdehnung des Kohrmantels 1 kann sich dieser mittels der Bolzen 5 relativ zum Laufringfuß verschieben, wobei die Mitnahme des Laufringes in ümfangsrichtung gesichert ist. On the rotary drum 1, the support plates 2 are welded next to one another at a distance in the circumferential direction of the drum. The guide plates 3 are in turn attached to these by welding. Between the opposing guide plates 3, the race 4 is guided with radial play with respect to the pipe jacket 1 or the support plates 2. The connection of the race foot with the guide plates 3 is made by the bolts 5 »which run radially to the furnace tube. The bolts 5 are located in bores half of which are provided in the race foot and half in the guide plates 3. The bolts 5 are welded to the guide plates 3 on one side at their upper end. When the barrel jacket 1 expands, it can be displaced relative to the base of the barrel by means of the bolts 5, the entrainment of the barrel being secured in the circumferential direction .
