等間隔に形成されてなつている。 In FIGS. 4 and 5, the rotary retort furnace 1 has a cylindrical furnace core tube 3 mounted on the upper surface of an underframe 2 in a slightly inclined state such that the discharge port 3a is located below the insertion port 3b, and is oriented approximately horizontally. It is located in The outer periphery of the furnace core tube 3 is surrounded by a heat retaining section 4 made of a heat-resistant furnace material. A heating section 5 is arranged between the heat retaining section 4 and the furnace core tube 3. A screw-shaped guide vane 6 and a supply hopper 7 communicating above the guide vane 6 are provided on the insertion port 3b side of the furnace core tube 3. The guide vanes 6 and the furnace core tube 3 are rotated at predetermined rotational speeds by drive motors 19 and 8, respectively. The inner surface of the furnace core tube 3 is formed into a smooth surface, and a beater member 9 is disposed inside thereof in the axial direction. As shown in FIG. 5, this beater member 9 has a plurality of beater units 10 arranged in the axial direction and detachably connected to each other. Each beater unit 10 has a plurality of blades 12 formed at equal intervals in the radial direction of the shaft tube 11.

３内壁への付着を防止する。 Due to the rotation of the furnace core tube 3, the beater member 9 also rotates so as to roll on the inner wall surface of the furnace core tube 3, and each time the wing pieces 12 fall down, they strike the furnace core tube 3, thereby reducing the impact and scraping action. This prevents the material to be heat-treated from adhering to the inner wall of the furnace core tube 3.

However, in the furnace core tube 3, the discharge port 3a side is the insertion port 3b.
Because it is slanted so that it is located lower than the side,
The beater unit 10 on the side of the discharge port 3a receives the component force of the load of the other beater unit 10, and rotational friction becomes large, and the rotational speed becomes slow. Furthermore, since the resistance of the object to be heat treated is also non-uniform within the furnace core tube 3, the rotational speed of each beater 10 is further different. As a result, there is a problem that the two fitting protrusions 13, 13 are easily damaged due to torsional moment and shearing force acting on them.
そこで、本発明は上記問題点を解決するために
案出されたもので、ビーター単体の破損を防止す
