Description
Befestigung der Flohronden von Rauchgasvorwärmern in ihren Sammelkästen. Die Erfindung. "betrifft eine Befestigung der Rohrenden der Rauchgasvorwärmer in ihieii 5`ä.mmelkästen, bei der die kegelförmig angespitzten oder aufgeweiteten Rohrenden in oder über entsprechende kegelförmige Flächen der Rohrstutzen der Kästen geschoben werden.Fastening the flue tubes of flue gas preheaters in their collecting boxes. The invention. "relates to a fastening of the pipe ends of the flue gas preheater in ihieii 5`ä.mmelkästen, in which the conical pointed or widened pipe ends pushed into or over corresponding conical surfaces of the pipe socket of the boxes will.
Gemäß der Erfindung soll der auf Zug beanspruchte Teil des Rohres oder der Rohrstutzen mit einem Spannring umgeben sein, der die Zugspannungen aufnimmt.According to the invention, the part of the pipe which is subject to tensile stress or the pipe socket can be surrounded by a clamping ring that absorbs the tensile stresses.
In der Zeichnung ist die Erfindung in mehreren Ausführungsbeispielen dargestellt, und zwar zeigen: Abb. i die neue Befestigungsart, Abb. 2 einen wagerechten Schnitt nach Linie a-a der Abb. i mit Spannring.In the drawing, the invention is shown in several exemplary embodiments shown, namely: Fig. i the new type of fastening, Fig. 2 a horizontal one Section along line a-a of Fig. I with clamping ring.
Der untere Sammelkasten 3' ist außen mit kegelförmigen Stutzen 5 ausgerüstet. Das untere Ende 6 der Rohre 2' ist kegelförmig aufgeweitet und mit dieser Aufweitung über die kegelförmigen Stutzen 5 gepreßt. Um ein Auseinandersprengen des unteren Rohrendes zu verhüten, ist es mit einem Ring -7. (Schrumpfring) versehen. Das obere Ende 8 des Rohres 2' ist außen ebenfalls mit einer kegelförmig auslaufenden Fläche 9 versehen. Dieses Rohrende 8, das auch innen kegelförmig gestaltet ist, wird in eine entsprechende keilförmige Nut io an der Unterseite der oberen Sammelkästen q.' eingepreßt. Das Rohrende 8 oder die Innen- oder Außenwand der Ringnut io können mit Schlitzen versehen sein, um eine elastischere Verbindung zu sichern. Auch kann die Außenwand der Ringnut mit einer Spannvorrichtung 12 (Abb. 2) versehen sein.The lower collecting tank 3 'is equipped with conical connecting pieces 5 on the outside. The lower end 6 of the tubes 2 'is widened conically and with this widening pressed over the conical nozzle 5. To break apart the lower one To prevent the end of the pipe, it is with a ring -7. (Shrink ring). The top The end 8 of the tube 2 'is also on the outside with a conically tapering surface 9 provided. This pipe end 8, which is also conical on the inside, is shown in FIG a corresponding wedge-shaped groove io on the underside of the upper collecting tanks q. ' pressed in. The pipe end 8 or the inner or outer wall of the annular groove io can be provided with slots to ensure a more elastic connection. Also can the outer wall of the annular groove can be provided with a clamping device 12 (Fig. 2).
