  Reinigungsvorrichtung für Rohre, insbesondere Rippenrohre von Ekonomisern. 
 EMI1.1 
 



   Bei der in Fig. 3 veranschaulichten Ausführung der Reinigungsvorrichtung erhält die Bürste e während ihrer Fortbewegung zwischen den Rohrreihen auch eine umlaufende Bewegung um ihre Achse. Auf der Bürstenstange sitzen Zahnräder g (Fig. 4), die mit unbeweglichen Zahnstangen h in Eingriff stehen, welche parallel zur Bewegungsrichtung der   Längsstücke   der Kette a angeordnet sind. Bei der Bewegung der Kette a rollen die Zahnräder g längs der Zahnstangen   h   ab und bewirken die Drehung der Bürste e um ihre Achse. Die Zahnstangen h sind zweckmässig mittels Rohrschellen (nicht dargestellt) auf den Rohren aufgehängt. Bei sehr grosser Zahl der Rohrreihen können diese in zwei oder mehrere Gruppen geteilt und für jede Gruppe eine Reinigungsvorrichtung nach der Ei findung vorgesehen werden.

  Cleaning device for pipes, in particular finned pipes for economizers.
 EMI1.1
 



   In the embodiment of the cleaning device illustrated in FIG. 3, the brush e is also given a rotating movement about its axis during its movement between the rows of tubes. On the brush rod sit gears g (Fig. 4) which are in engagement with immovable racks h, which are arranged parallel to the direction of movement of the longitudinal pieces of the chain a. When the chain a moves, the toothed wheels g roll along the toothed racks h and cause the brush e to rotate about its axis. The racks h are expediently suspended on the pipes by means of pipe clamps (not shown). If the number of rows of tubes is very large, they can be divided into two or more groups and a cleaning device can be provided for each group according to the egg finding.

Claims

PATENT CLAIMS: 1. Cleaning device for pipes, in particular finned pipe from economizers, with brushes, the ends of which are suspended in rotating endless chains guided over rollers, characterized in that each of the endless chains (a) driven by a single common shaft (d) in line - 'or loop shape is passed through all the spaces between the rows of pipes so that each brush (s) successively sweeps all these spaces to clean the pipes.

2. Cleaning device according to claim 1, characterized in that the brushes (a) are set in rotation around their axis when passing between the rows of tubes, for example by means of gear wheels (g) seated on the brush shaft, which during the movement of the brushes (e) longitudinally Unroll immovable racks (h).
