[0033] Working Principle: When the starting device heats up, the material is fed through the funnel-type feed block 6 and falls into the annular heating furnace 2 below via the conveyor box 12. The servo motor 19 is started, and its output shaft drives the connecting rod 22 to rotate. During the rotation of the connecting rod 22, a set of metal annular plates 27 fixedly connected to its surface also rotates. The waste activated carbon falling into the annular heating furnace 2 comes into contact with the set of metal annular plates 27 and rotates with them. The metal annular plates 27 have gaps. As they rotate, the waste activated carbon is blocked by the fixing rod 23 fixed to the inner wall of the annular heating furnace 2. After being blocked, it falls through the gaps to the bottom of the annular heating furnace 2 below. This structure allows the waste activated carbon to roll, thus making full contact with the hot air. In addition, the set of metal annular plates 27 are all made of metal. After contacting the hot air, the surface heats up, improving the heating effect of the waste activated carbon.

The heating coil 21 is started by the main controller 7. The heating coil 21 is heated by the heat generated by the resistance when current passes through the conductor. The inner wall of the annular heating furnace 2 is equipped with a temperature sensor 25. The temperature of the heating element is monitored by the temperature sensor 25. Then, the current or power supply is adjusted through the feedback loop to maintain the required temperature. The temperature is intelligently controlled and has a high degree of intelligence.

[0035] A ring-shaped heating furnace 2 is fixedly connected inside the limiting and fixing frame 1. A recovery filter box 4 is set on the left side of the ring-shaped heating furnace 2. A conveying connection pipe 5 is set on the upper surface of the ring-shaped heating furnace 2 and the recovery filter box 4. The conveying connection pipe 5 is connected to both. When the ring-shaped heating furnace 2 generates organic gas and char powder during use, the conveying fan 16 is started to operate. The organic gas and char powder in the ring-shaped heating furnace 2 are conveyed to the recovery filter box 4 through the conveying connection pipe 5 and filtered by the square filter plate 13. After the char powder is filtered, the filtered organic gas is returned to the ring-shaped heating furnace 2 through the conveying pipe 15 for combustion, realizing the recovery and utilization of heat energy.

[0036] During the feeding process, the servo motor 34 is started, and its output shaft drives the rotating threaded rod 32 to rotate. The rotating threaded rod 32 has a threaded design. During the rotation, it conveys the waste activated carbon in the funnel-shaped feed block 6, realizing automated feeding. The waste activated carbon is conveyed to the conveying box 12 by rotating the threaded rod 32. The conveying box 12 is rotatably connected to a rotating block 37, which is in close contact with the inner wall of the conveying box 12. The servo motor 30 is started, and its output shaft drives the rotating block 37 to rotate. The rotating block 37 has a square limiting groove 38 on its surface.
