Abstract

When a running ring is fastened to the shell of a rotary tube, the lining plates located between the running ring and the shell of the rotary tube must be secured by retaining elements against displacement both in the longitudinal direction of the rotary tube and in the radial direction, since otherwise not only are the lining plates rapidly destroyed but damage is also caused to the shell of the rotary tube. According to the invention, the retaining elements 5, 6 for the lining plates 3 are fastened to the supporting elements 4 which are arranged offset from one another on both sides of the running ring 1, the retaining elements 5, 6 - as viewed in the circumferential direction of the rotary tube 2 - projecting on both sides of the supporting elements 4 and supporting the lining plates 3 from above. In this way, not only are the lining plates 3 reliably locked both in the longitudinal direction of the rotary tube and in the radial direction and the service life of the lining plates 3 is thereby increased, but the exchange of the lining plates is also considerably facilitated as a result. <IMAGE>

   Gemäss einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Futterbleche von oben gesehen-rechteckig ausgebildet-und an einer Stirnseite mit einer Ausnehmung versehen, die in das jeweils auf der gegenüberliegenden Seite des Laufringes befindliche Stützelement eingreift. Auf diese Weise kann sehr vorteilhaft das Futterblech ohne besondere Arretierungselemente auf dem Drehrohrmantel, insbesondere in Umfangsrichtung gesehen, in seiner Lage festgehalten werden. 



   Die Erfindung wird an Hand eines schematischen Ausführungsbeispieles nachfolgend näher erläutert : Es zeigen : Fig. 1 einen Teillängsschnitt durch einen Laufringschuss eines Drehrohrofens mit Futterblech und Laufring, Fig. 2 eine Draufsicht auf den Drehrohrofenmantel gemäss   Fig. l,   Fig. 3 eine Draufsicht auf ein Futterblech gemäss der Erfindung. 



   Wie die Fig. l und 2 zeigen, sind zwischen dem Laufring-l-und dem Mantel eines Drehrohrofens --2-- mehrere, auf dem Mantelumfang gleichmässig verteilte Futterbleche--3-lose angeordnet. Zu beiden Seiten des   Laufringes-l-befinden   sich   Stützelemente--4--,   die am   Drehrohrofenmantel --2-- angeschweisst sind.   Diese   Stützelemente --4-- sind,   wie Fig. 2 zeigt, jeweils abwechselnd auf der einen und auf der andern Laufringseite versetzt gegeneinander angeordnet. Die   Stützelemente --4-- dienen   in erster Linie zur sicheren Halterung des Laufringes - in seiner Lage. 



   Im übrigen besteht das   Stützelement --4-- aus   zwei Teilen,   u. zw.   aus einer am Laufring -   anliegenden Führungsleiste --4'-- und   aus einem diese Leiste haltenden, auf dem Drehrohr- 
 EMI2.1 
 am Drehrohrmantel vornehmen zu müssen. 



   An den   Stützelementen --4-- sind   ferner Halteelemente--5 und   6-- für   die Futterbleche - angeordnet, derart, dass sie-in der Umfangsrichtung des Drehrohrofens gesehen-zu beiden Seiten über die   Stützelemente --4-- hinauskragend   die Futterbleche --3-- von oben her abstützen. Die Halteelemente --5-- sind hiebei im Querschnitt rechteckig ausgeführt, während die Halteelemente --6-- aus einfachen Winkeleisen bestehen. Durch die Halteelemente --5 und
6-- werden die Futterbleche --3-- sowohl in der Drehrohrofenlängsrichtung als auch in axialer Richtung in ihrer Lage festgehalten. 



   Wie Fig. 3 zeigt, ist das Futterblech --3-- jeweils rechteckig ausgebildet und an einer Stirnseite mit einer   Ausnehmung --7-- versehen.   Dieses   Futterblech --3-- wird   bei der Montage von der Seite her in der Pfeilrichtung --8-- zwischen den   Stützelementen --4-- einerseits   und dem Laufring-l-und dem Drehrohrofenmantel --2-- anderseits eingeschoben, u. zw. so weit, bis dass die innere Stirnfläche der Ausnehmung --7-- fest an der Innenkontur des   Stützelementes --4-- anliegt.   



  Auf diese Weise wird ein zahnartiger Eingriff des   Stützelementes --4-- in   die Ausnehmung --7-des Futterbleches --3-- erreicht, und dadurch das Futterblech in seiner Lage festgehalten. 



  Anschliessend werden an den   Stützelementen --4-- die Halteelemente --5 und 6-- angeschweisst,   und dadurch das Futterblech sowohl in der Drehrohrofenlängsrichtung als auch in radialer Richtung festgehalten. Die Futterbleche --3-- sind ferner sehr vorteilhaft-in Umfangsrichtung des Drehrohrofens --2-- gesehen - mit Abstand --9-- voneinander angeordnet. Hiedurch wird nicht nur sehr vorteilhaft eine bessere Kühlung des Laufringes erreicht, sondern hiedurch kann auch der Verschleiss des Laufringes leichter kontrolliert werden.

   Ein weiterer Vorteil der erfindungsgemässen Vorrichtung mit den Futterblechen zwischen dem Laufring und dem Mantel des Drehrohrofens besteht darin, dass durch die Ausnehmung --7-- in den Futterblechen --3-- ein zahnartiger Eingriff der   Stützelemente --4-- erreicht   wird, der in sehr einfacher Weise einen besonders sicheren Halt der   Futterbleche --3-- gegen   ein Verschieben in der Trommelumfangsrichtung gewährleistet. Wenn die Futterbleche verschlissen sind, können sie leicht von einer Seite des Laufringes her ausgewechselt werden. Um die verschlissenen Futterbleche --3-- gegen neue Futterbleche auszuwechseln, bedarf es hiebei lediglich der Beseitigung und Wiederanbringung der Halteelemente --5 und 6--.

   Da diese Halteelemente --5 und 6-- aber nicht am Mantel des Drehrohrofens sondern nur an den Stützelementen befestigt sind, entfallen bei Reparatur- oder Montagearbeiten im Bereich der Laufringanordnung alle Schweiss- und Fugarbeiten am Drehrohrofen.

   According to a further advantageous embodiment of the invention, the lining plates are rectangular when viewed from above and are provided on one end face with a recess which engages in the support element located on the opposite side of the race. In this way, the lining plate can be held in its position without any special locking elements on the rotary tube jacket, particularly when viewed in the circumferential direction.



   The invention is explained in more detail below on the basis of a schematic exemplary embodiment: FIG. 1 shows a partial longitudinal section through a race ring section of a rotary kiln with casing plate and race, FIG. 2 shows a plan view of the rotary kiln jacket according to FIG. 1, FIG. 3 shows a plan view of a Lining sheet according to the invention.



   As FIGS. 1 and 2 show, between the race ring 1 and the casing of a rotary kiln - 2 - several lining plates - 3-loosely distributed on the casing circumference - are arranged in a loose arrangement. On both sides of the race-l-are support elements - 4--, which are welded to the rotary kiln jacket --2--. These support elements --4-- are, as shown in Fig. 2, alternately offset on one side and on the other side of the race. The support elements --4-- primarily serve to securely hold the race - in its position.



   Otherwise, the support element --4-- consists of two parts, u. between a guide bar --4 '- resting on the race and a bar holding this bar on the rotary tube
 EMI2.1
 to have to make on the rotary tube jacket.



   On the support elements --4-- are also holding elements - 5 and 6-- for the casing sheets - arranged in such a way that - seen in the circumferential direction of the rotary kiln - they protrude on both sides over the support elements --4-- the casing sheets --3-- Support from above. The holding elements --5-- are rectangular in cross-section, while the holding elements --6-- consist of simple angle irons. Through the holding elements --5 and
6-- the lining plates --3-- are held in their position both in the longitudinal direction of the rotary kiln and in the axial direction.



   As shown in Fig. 3, the lining plate --3-- is each rectangular and provided with a recess --7-- on one end face. This lining plate --3-- is inserted from the side in the direction of the arrow --8-- between the support elements --4-- on the one hand and the race ring-l and the rotary kiln jacket --2-- on the other, u . Between until the inner end face of the recess --7-- is tight against the inner contour of the support element --4--.



  In this way, a tooth-like engagement of the support element --4-- in the recess --7-of the lining plate --3-- is achieved, and thereby the lining plate is held in its position.



  The holding elements --5 and 6-- are then welded to the support elements --4--, thereby holding the casing in place both in the longitudinal direction of the rotary kiln and in the radial direction. The lining plates --3-- are also very advantageous - seen in the circumferential direction of the rotary kiln --2-- - at a distance --9-- from each other. This not only very advantageously achieves better cooling of the race, but also makes it easier to control the wear of the race.

   Another advantage of the device according to the invention with the lining plates between the race and the jacket of the rotary kiln is that the recess --7-- in the lining plates --3-- results in a tooth-like engagement of the support elements --4--, which ensures a particularly secure hold of the chuck plates --3-- against shifting in the drum circumferential direction in a very simple manner. If the lining plates are worn out, they can easily be replaced from one side of the race. To replace the worn lining plates --3-- with new lining plates, all that is required is to remove and reinstall the holding elements --5 and 6--.

   Since these holding elements --5 and 6-- are not attached to the casing of the rotary kiln but only to the support elements, all welding and joining work on the rotary kiln is not necessary for repair or assembly work in the area of the race arrangement.
