The conveying device 3 and the pulling device 6 are controlled by the control panel 2. Flip-door devices 7 are installed on both sides of kiln 1. The flip-door device 7 includes a limiting frame 71, a limiting groove 72, a sliding block 73, a spring 74, a rotating disc 75, and a horizontal sliding groove 76. The sliding block 73 is slidably connected within the limiting groove 72. The rotating disk 75 axially penetrates the internal cavity of the sliding block 73. Both ends of the rotating disk 75 are slidably connected to the inner wall of the sliding block 73 through rotating bearings. The right end of the horizontal sliding groove 76 is fixedly connected to the limiting groove 72. The bottom of the limiting frame 71 is slidably connected to the horizontal sliding groove 76. The left end of the rotating disk 75 moves up and down within the limiting frame 71. The right end of the rotating disk 75 is fixedly connected to the end of the long column at the lower end of the sliding block 73 through a spring 74. The right end of the limiting groove 72 is fixedly connected to the inner wall of the kiln 1.
[0015] The kiln 1 includes a kiln body 11 and a rotating door 12. The rotating door 12 is installed on both sides of the kiln body 11. The output end of the rotating shaft disk 75 is fixedly connected to the rotating door 12. The rotating door 12 and the kiln body 11 have a close and smooth contact surface, which ensures the flexibility of the rotating door 12 in the rotation of the kiln body 11, while ensuring the heat preservation capacity of the kiln 1.
[0016] The snap-fit groove 5 has a sliding groove 51. The snap-fit groove 5 is installed on the left and right sides of the edge of the kiln 1 to limit the offset of the moving door 4 and improve the stability of the opening and closing of the moving door 4.
[0017] The sliding door 4 includes a sliding door body 41 and slider wheels 42. Slider wheels 42 are installed at the four corners of the sliding door body 41. The slider wheels 42 slide in the groove of the slide rail 51, and the contact surfaces are close and smooth, which makes the sliding door 4 move smoothly and stably.
[0018] The front end of the sliding block 73 is fixedly connected to the movable door 4. When the movable door 4 closes and opens, it drives the sliding block 73 to rotate the flip door 12 180 degrees to achieve the exchange of the inner and outer walls of the kiln 1.

The slider wheel 42 of the sliding door 4 moves smoothly in the slide groove 51 to achieve opening and closing. Meanwhile, the movement of the sliding door 4 is achieved by the sliding block 73 sliding within the limiting slot 72. The sliding block 73 drives the rotating disk 75 to move up and down within the limiting frame 71. The output end of the rotating disk 75 reaches the bottom triangle and the upper hole of the limiting frame 71 to complete the 180° rotation of the flip door 12, turning the ash-accumulated surface of the inner wall of the kiln 1 into the outer wall for easy cleaning. During this process, the spring 74 assists the rotating disk 75 in resetting and rotating through elastic deformation, and the horizontal sliding groove 76 ensures the stability of the sliding trajectory of the limiting frame 71. Ash and slag fall from the bottom of kiln 1 into conveying device 3 and are automatically transported to achieve continuous ash discharge; When the sliding door 4 is closed, the sliding block 73 moves in the opposite direction, the rotating disc 75 is reset under the action of the spring 74, and the flip door 12 returns to its original position and fits tightly against the kiln body 11 to ensure sealing. The entire process is coordinated by the control panel 2, and no manual intervention is required.
