[0016] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0017] like Figure 1The present invention discloses a stirring device for the activated carbon kneading and molding process based on steam heating, comprising a stirring tank 1 and a steam generator 2. A rotating shaft 3 is mounted inside the stirring tank 1, and a driving mechanism 4 for driving the rotating shaft 3 to rotate is fixed on the stirring tank 1. A stirring paddle 5 is fixed on the rotating shaft 3 inside the stirring tank 1. An air inlet channel 301 and an exhaust channel 302 are provided inside the rotating shaft 3. The air inlet channel 301 is connected to the air outlet of the steam generator 2. An air delivery channel 501 is provided on the stirring paddle 5, which is connected to the air inlet channel 301 and the exhaust channel 302 respectively. The stirring paddle 5 is made of a heat-conducting material.

[0018] The mixing tank 1 has a feed inlet at the top and a collection hopper at the bottom, with a discharge outlet at the bottom of the collection hopper. The axis of the mixing tank 1 extends vertically, as does the axis of the rotating shaft 3. The air inlet channel 301 and the exhaust channel 302 extend axially along the rotating shaft 3. Insulation materials can be provided on the rotating shaft 3 to wrap the air inlet channel 301 and the exhaust channel 302 respectively. The drive mechanism 4 is existing technology and can be a motor. The exhaust channel 302 is connected to the air inlet of the steam generator 2. The sealing device is existing technology and can be made of wear-resistant and high-temperature resistant material.

[0019] Activated carbon, binders such as coal tar, and additives are added to the mixing tank 1. The drive mechanism 4 is started, and the drive mechanism 4 drives the stirring paddle 5 to rotate in the mixing tank 1 through the rotating shaft 3. The stirring paddle 5 continuously stirs the raw materials in the mixing tank 1. The steam generator 2 is started, and the steam generator 2 inputs steam into the air inlet channel 301 of the rotating shaft 3. The steam passes through the air inlet channel 301 and enters the air delivery channel 501. The steam dissipates heat into the mixing tank 1 through the stirring paddle 5. The stirring paddle 5 continuously heats the raw materials while stirring them, so that the raw materials maintain a certain temperature. The steam and / or water that have completed the heat dissipation enter the exhaust channel 302 through the air delivery channel 501 and are discharged through the exhaust channel 302.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the rotating shaft 3 has an air inlet 304 connected to the air inlet channel 301 and an exhaust port 305 connected to the exhaust channel 302. A sealing device 6 is fitted on the rotating shaft 3 and fits against the outside of the rotating shaft 3. The rotating shaft 3 is rotatably mounted inside the sealing device 6, and the air inlet 304 and the exhaust port 305 are located inside the sealing device 6. The sealing device 6 has two through holes. The openings of the two through holes face the movement trajectories of the air inlet 304 and the exhaust port 305, respectively.

The through hole with the opening facing the movement trajectory of the exhaust port 305 is connected to the air inlet of the steam generator 2.

[0021] The rotating shaft 3 rotates within the sealing device 6, causing the air inlet 304 and the exhaust port 305 to rotate. When the air inlet 304 rotates to the through hole with its opening facing the trajectory of the air inlet 304, the air inlet 304 and the exhaust port of the steam generator 2 are connected, and the steam output by the steam generator 2 enters the air inlet channel 301. When the exhaust port 305 rotates to the through hole with its opening facing the trajectory of the exhaust port 305, the exhaust port 305 is connected to the outside, and the steam and / or water in the exhaust channel 302 are discharged.

[0023] For the heat-dissipating steam to be transferred in the intake passage 301, and for the heat-dissipating steam and / or water to be transferred in the exhaust passage 302, the heat insulation layer 303 isolates the intake passage 301 and the exhaust passage 302 to prevent heat exchange between the intake passage 301 and the exhaust passage 302.

[0024] In actual production, activated carbon, binders such as coal tar, and additives are added to the mixing tank 1; the drive mechanism 4 is started, which drives the rotating shaft 3 to rotate within the sealing device 6; the rotating shaft 3 drives the stirring paddle 5 to rotate within the mixing tank 1 and continuously stirs the raw materials within the mixing tank 1; the steam generator 2 is started, and the exhaust port 305 of the steam generator 2 continuously outputs steam, while the rotating shaft 3 drives the air inlet 304 and the exhaust port 305 to rotate within the sealing device 6; when the air inlet 304 rotates to the through hole whose opening faces the trajectory of the air inlet 304, the air inlet 304 and the steam generator... The outlet of device 2 is connected, and the steam output from steam generator 2 enters the inlet channel 301. The steam passes through the inlet channel 301 and enters the delivery channel 501. The heat is dissipated into the mixing tank 1 by the stirring paddle 5. The stirring paddle 5 continuously heats the raw material while stirring it, so that the raw material maintains a certain temperature. The steam and / or water that have completed the heat dissipation enter the exhaust channel 302 through the delivery channel 501. When the exhaust port 305 rotates to the through hole facing the trajectory of the exhaust port 305, the exhaust port 305 is connected to the outside, and the steam and / or water in the exhaust channel 302 is discharged.
