Description

Technical Field

[0001] The invention relates to the technical field of carbon nanotube processing, and more specifically, to a purification device for carbon nanotube materials. Background Art

[0002] During the large-scale production process, the carbon nanotubes produced often contain more impurities, such as amorphous carbon, fullerenes, catalysts and nanocarbon capsules. These impurities will affect the physical, chemical and electrochemical properties of carbon nanotubes and limit their application in various fields.

[0003] At present, the carbon nanotube purification equipment on the market needs to treat the chlorine-containing gas after the reaction in the purification furnace after purifying the carbon nanotubes to prevent metal catalyst impurities or other impurities from being adsorbed together with the purified carbon nanotubes again, resulting in substandard purification. The chlorine-containing gas is discharged into a solid adsorption medium through a pipeline and then treated.

[0004] However, since the chlorine-containing gas is directly extracted from the purification furnace, it will cause dust problems of carbon nanotubes. During the dust generation process, the carbon nanotubes will be re-adsorbed with the metal catalyst impurities mixed in the chlorine-containing gas. Since carbon nanotubes have a high specific surface area and a unique surface structure, they can adsorb various gases and particulate matter. After purification, the impurity carbon on the carbon nanotubes is oxidized and the catalyst nanoparticles are exposed. During the dust generation process, the metal catalyst particles exposed by the metal catalyst impurities will react with the chlorine atoms in the chlorine-containing gas to form metal chlorides and be re-adsorbed, resulting in the carbon nanotubes not meeting the purification standards.

The high-temperature purification furnace is heated to a preset temperature (the preset temperature is between 800 degrees and 1200 degrees). At the preset temperature, the metal impurities in the carbon nanotubes to be purified react with the chlorine-containing gas to generate low-boiling point metal chlorides.

[0052] The first cylinder 23 and the second cylinder 24 provide conditions for the sliding of the sealing cover 25. When the output ends of the two groups of the first cylinder 23 and the second cylinder 24 are extended, the two sealing covers 25 are fitted together to seal the reaction furnace 13. When the output ends of the two groups of the first cylinder 23 and the second cylinder 24 are retracted, the two sealing covers 25 are driven back to the sliding groove 26, and the output ends of the two groups of the first cylinder 23 and the second cylinder 24 can slide in the sealing plate 21.

[0054] The exhaust furnace 31 can collect the gaseous form of the metal chloride, and the exhaust port 32 is composed of an exhaust valve and an exhaust pipe. When the exhaust valve is opened, the gaseous form of the metal chloride is discharged through the exhaust pipe.

[0055] See also Figures 3 to 9 The covering component 4 is made of high temperature resistant material. The covering component 4 includes a covering top plate 41. A connecting telescopic rod 43 is symmetrically installed below the covering top plate 41. A connecting telescopic cylinder 48 is symmetrically installed above the covering top plate 41 at a position that fits with the connecting telescopic rod 43. A fixing device 45 is installed at the output end of the two connecting telescopic rods 43. A shielding device 46 is arranged below the fixing device 45. The shielding device 46 includes a plurality of shielding plates 462. A shielding connecting block 461 is installed on the shielding plate 462. A second rotating shaft 463 is rotatably installed in the middle of the shielding connecting block 461. The second rotating shaft 463 is hinged to the fixing device 45.

[0056] The covering top plate 41 can close the top of the exhaust furnace 31, and the connecting telescopic rod 43 limits the synchronous rotation of the fixing device 45. The shielding device 46 is used to cover the purified carbon nanotubes. Multiple shielding plates 462 cooperate to shield the carbon nanotubes to avoid secondary combination of carbon nanotubes and metal chlorides after dust is generated. The second rotating shaft 463 rotates on the shielding connecting block 461.

[0057] The covering assembly 4 includes a driving motor 42 , which is installed above the covering top plate 41 . The output end of the driving motor 42 penetrates the covering top plate 41 and is rotatably installed with a rotating telescopic rod 44 , and a linkage device 47 is fitted below the rotating telescopic rod 44 .

[0058] The driving motor 42 drives the rotating telescopic rod 44 to rotate, and the linkage device 47 drives the shielding device 46 to change.

[0059] The fixing device 45 includes a fixing plate 451, the top of the fixing plate 451 is connected to the output ends of the two connecting telescopic rods 43, and the bottom of the fixing plate 451 is circularly and equidistantly installed with fixing blocks 452, and the middle of the fixing block 452 is rotatably installed with a first rotating shaft 453, and the first hinge block 454 is installed on the first rotating shaft 453, and the first hinge block 454 is respectively connected to the first rotating shaft 453 and the second rotating shaft 463.

[0060] The fixed plate 451 is used for supporting and fixing. The two connected telescopic rods 43 can drive the rotating telescopic rod 44 to extend synchronously. The first rotating shaft 453 can rotate on the fixed block 452. The first hinge block 454 connects the first rotating shaft 453 and the second rotating shaft 463, so that the shielding plate 462 can rotate relative to the fixed plate 451 through the first hinge block 454.

[0061] The rotatable telescopic rod 44 includes an extended end 441, and a matching thread 442 is arranged below the extended end 441. The linkage device 47 includes a linkage block 471, and the linkage block 471 is fitted and installed with the matching thread 442. The side wall of the linkage block 471 is circularly and equidistantly provided with linkage mounting blocks 472, and a hinged rod 473 is rotatably installed on the linkage mounting block 472.

[0062] The output end of the telescopic cylinder 48 penetrates the covering top plate 41 and is connected to the extending end 441. The extending end 441 can extend downward to drive the rotating telescopic rod 44 to move downward. When the rotating telescopic rod 44 rotates, the linkage block 471 can move downward through the matching thread 442. When the linkage block 471 moves downward, it synchronously drives the articulated rod 473 to move downward.

[0063] A shielding fixed block 465 is installed in the middle position above the shielding plate 462, and a second hinge block 464 is rotatably installed on the shielding fixed block 465. The end of the hinge rod 473 away from the linkage mounting block 472 is connected to the second hinge block 464, and the second hinge block 464 is respectively connected to the hinge rod 473 and the shielding fixed block 465.

[0064] When the hinged rod 473 moves downward, the angle between the hinged rod 473 and the shielding fixed block 465 gradually becomes vertical through the second hinged block 464, and a solid adsorption medium (solid adsorption medium includes activated carbon, molecular sieve, adsorption resin, etc.) is arranged above the shield 462 to adsorb impurities, and the shield 462 rotates downward until the shields all hang down.

[0065] By arranging a solid adsorption medium above the baffle 462, when the baffle moves upward, the problem of secondary contamination of the purified carbon nanotubes by inert gas and chlorine gas containing impurities that are not completely discharged can be avoided.

[0066] When the carbon nanotubes to be purified are introduced into the reactor 13, the sealing cover 25 is opened, inert gas is introduced, oxygen in the furnace is discharged through the exhaust port 32, and chlorine is introduced. When the gas ratio reaches the standard, the sealing cover is closed, and the reactor 13 is heated to a preset temperature. At the preset temperature, the metal impurities in the carbon nanotubes to be purified react with the chlorine-containing gas. After the reaction is completed, the two groups of first cylinders 23 and second cylinders 24 drive the two sealing covers 25 to open, the driving motor 42 rotates forward to drive the rotating telescopic rod 44 to rotate, the linkage block 471 moves downward, and the multiple shields 462 are opened. The two connecting telescopic rods 43 extend toward the purified carbon nanotubes, synchronously driving the rotating telescopic rods 44. When the inert gas and chlorine are extended to approach the carbon nanotubes, the driving motor 42 is reversed, the linkage block 471 moves upward, and the multiple shielding plates 462 are closed. Nitrogen is introduced into the reaction furnace 13 through the nitrogen ventilation pipe. The nitrogen is used as a carrier to lift the inert gas and chlorine upward and prevent the carbon nanotubes from being lifted. When the inert gas and chlorine rise into the exhaust furnace 31, the inert gas and chlorine are discharged through the exhaust port 32. When the inert gas and chlorine rise upward, the temperature has dropped. After being discharged, the closed shielding plates 462 are driven to move upward through the two connecting telescopic rods 43 to avoid the problem that some metal chlorides are still in gaseous form or other impurities are solidified, and the impurities are adsorbed to prevent them from falling.

[0067] By setting the drive motor 42 to rotate forward to drive the telescopic rod 44 to rotate, the multiple shielding plates 462 are opened when the linkage block 471 moves downward. When approaching the carbon nanotubes, the drive motor 42 is reversed to drive the linkage block 471 to move upward, and the multiple shielding plates 462 are closed, thereby achieving the effect of preventing the carbon nanotubes from raising dust during the gas replacement process.

[0068] Nitrogen is introduced into the reaction furnace 13 through a nitrogen ventilation pipe, and the nitrogen is used as a carrier to lift the inert gas and chlorine upward. When the inert gas and chlorine rise to the exhaust furnace 31, the inert gas and chlorine are discharged through the exhaust port 32, thereby achieving the effect of lifting the inert gas and chlorine containing impurities upward to avoid secondary pollution of the carbon nanotubes.
