An arc-shaped baffle is arranged between the limiting rings. Through the arranged arc-shaped baffle, the feeding ports can be blocked to prevent the tail gas from leaking during drying and thus polluting the environment.

[0007] Further, in order to facilitate the collection and discharge of the waste gas, the upper cover is set as a conical structure, and the upper end of the upper cover is the small end.

[0008] Further, in order to facilitate the opening operation of the arc-shaped baffle, a handle is provided on the arc-shaped baffle.

[0009] Further, in order to facilitate the fixing of the drying round cover on the upper cover, a plurality of rotating protrusions are provided on the outer periphery of the lower end of the upper cover.
