When the activated carbon activating device is used, the electromagnetic valve of the feeding hole 3 is opened, charcoal obtained by burning wood is taken out of the burning furnace and poured into the activated carbon activating device from the feeding hole 3, the electromagnetic valve of the feeding hole 3 is closed, the motor 1 is started to rotate positively, and the electromagnetic valves on the first oxygen pipe 61 and the second oxygen pipe 62 are opened simultaneously; the motor 1 drives the rotating rod 5 to rotate positively, the rotating rod 5 drives the rotating inner box to rotate positively, when the rotating inner box rotates positively, the first spiral groove 27 on the inner wall of the rotating inner box rotates to drive the rotating ring 72, the stirring rod 73, the stirring blade 74, the electric heating ring 75 and the gear 76 in the stirring unit 7 to move upwards, in the process of moving upwards, charcoal to be activated is compressed, meanwhile, because the rotating ring 72 is in spiral transmission with the worm 71, when the rotating ring 72, the stirring rod 73, the stirring blade 74 and the electric heating ring 75 move upwards, the gear 76 is in meshing transmission with the rack 271 on the first spiral groove 27, the stirring rod 73 starts to rotate, when the stirring rod 73 rotates, the stirring blade 74 starts to rotate to fully stir the charcoal to be activated, at the moment, oxygen in the oxygen tank 6 flows into the rotating inner box through the first oxygen pipe 61 and the second oxygen pipe 62 via the second channel 25, oxidizing the charcoal to be activated; when oxygen is introduced into the rotary inner box to oxidize the charcoal, the electric heating ring 75 heats the charcoal to be activated, so that the charcoal activation time is shortened, and the charcoal activation efficiency is improved; when the rotating ring 72, the stirring rod 73, the stirring blade 74, the electric heating ring 75 and the gear 76 move to the top of the rotating inner box, the driving motor 1 rotates reversely, the rotating ring 72, the stirring rod 73, the stirring blade 74 and the electric heating ring 75 start to move downwards and rotate, and the charcoal is subjected to rotary stirring again to be rapidly activated; the charcoal can be stirred twice in a rotating way by the stirring unit 7 through one positive and negative rotation of the motor 1; when the rotary inner box rotates, the electromagnetic valve on the catalyst pipeline 81 is opened, the catalyst firstly enters the hollow cavity 23 and then enters the rotary inner box from the through hole to be contacted with the rotary charcoal to be activated, so that the catalyst is fully contacted with the charcoal to be activated; when the electric heating ring 75 heats the charcoal to be activated, a through hole is formed in the side wall of the rotating inner box, so that a part of heat is dissipated, when the rotating inner box rotates forwards, the second spiral groove 9 drives the magnetic block 91 to move upwards, the magnetic block 91 can push the heat dissipated by the electric heating ring 75 in the first channel 25 to enter the rotating inner box when moving upwards, meanwhile, when the magnetic block 91 moves upwards, the iron block 92 is driven to move upwards, so that oxygen in the second channel 26 can be rapidly compressed to enter the rotating inner box, and therefore the charcoal can be rapidly activated, and when the heat in the first channel 25 is in contact with the oxygen, the oxygen can be rapidly introduced into the rotating inner box; similarly, when the rotary inner box rotates reversely, the second spiral groove 9 drives the magnetic block 91 to move downwards, the magnetic block 91 can push heat dissipated by the electric heating ring 75 in the first channel 25 to enter the rotary inner box when moving downwards, and meanwhile, when the magnetic block 91 moves downwards, the iron block 92 is driven to move downwards, so that oxygen in the second channel 26 can be rapidly compressed to enter the rotary inner box, and the activation rate of charcoal is further improved; in the process of activating the charcoal in the rotary inner box, heat generated by burning wood raw materials in the combustion furnace enters the rotary inner box through the heat distribution pipeline, so that the activation of the charcoal can be accelerated; after the charcoal is activated, the charcoal enters the cooling chamber 4 through the cooling pipeline 41 to be cooled.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
