When the rotary kiln body 1 is shut down, the rotating plug-in plate 405 is plugged into the left end of the rotary kiln body 1, which can prevent the material inside the rotary kiln body 1 from flowing out from the left discharge port of the rotary kiln body 1 when the rotary kiln body 1 is shut down. Balls are rotatably installed on the circumferential surface of the inner ring of the rotating plug-in plate 405, and the balls are in contact with the circumferential outer surface of the right end of the burner 2. Through the setting of the balls, the rotating plug-in plate 405 can rotate smoothly on the burner 2, and a stirring blade 406 is provided on the right side surface of the rotating plug-in plate 405.

[0020] Among them, the right end of the rotary kiln body 1 is the feed port, and the left end is the discharge port. The right end of the burner 2 is arranged inside the left end of the rotary kiln body 1, so that the heat ejected by the burner 2 when working can smoothly enter the interior of the rotary kiln body 1 to heat the material. The rotating plug-in plate 405 is close to the side of the inner wall of the rotary kiln body 1 and contacts the inner wall of the rotary kiln body 1, so that when the rotating plug-in plate 405 rotates and stirs, the material staying at the left end of the rotary kiln body 1 can be stirred to avoid the material adhering to the inner wall of the rotary kiln body 1 to cause agglomeration, thereby improving the production quality when the rotary kiln body 1 is shut down.

[0021] In this embodiment, preferably, the front end of the servo motor 401 is provided with a driven stirring mechanism 5, and the driven stirring mechanism 5 includes a fixed block 501, and the fixed block 501 is arranged at the front end of the upper surface of the mounting seat 3, and a telescopic cylinder 502 is arranged inside the lower end of the fixed block 501, and a movable connecting block 503 is arranged at the right end of the telescopic cylinder 502.
