Description

Technical Field

[0001] The invention relates to the technical field of carbon nanotube production, in particular to a carbon nanotube purification device with a magnetic separation structure. Background Art

[0002] Carbon nanotubes are a new type of one-dimensional nanomaterial. Their production and purification require processes such as raw material preparation, carbon nanotube synthesis, impurity separation, purification, cleaning and purification, drying, and dispersion. Because of their excellent temperature resistance, electrical conductivity, thermal conductivity, chemical resistance, and mechanical properties, they are widely used in semiconductors, engineering plastics, new energy, and other fields.

[0003] In the prior art, carbon nanotubes are subjected to magnetic separation and impurity separation before purification. When the magnetic impurities are attracted and separated, a large number of carbon nanotubes are directly poured into the equipment for magnetic separation and impurity separation. Since the magnetic force generated by the magnetic separation structure at the same time is limited, when a large number of carbon nanotubes are magnetically separated at the same time, the magnetic separation structure cannot completely attract and separate the magnetic impurities contained in the large number of carbon nanotubes at the same time, resulting in low efficiency and effect when a large number of carbon nanotubes are subjected to magnetic separation and impurity separation, which is easy to affect the subsequent purification of the carbon nanotubes or the quality of the finished product.

DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0029] See also Figure 1 - Figure 8As shown, a purification device for carbon nanotubes with a magnetic separation structure comprises a box body 1; the top of the outer wall of the box body 1 is open; a group of support columns 2 are fixedly connected to the bottom end of the outer wall of the box body 1; a feed pipe 3 is fixedly connected to the center of the bottom end of the outer wall of the box body 1, and a first electric control valve is arranged in the feed pipe 3, and the feed pipe 3 is connected to the box body 1; a feed shell 4 is fixedly connected to the top end of the inner wall of the box body 1; a magnetic separator is arranged at the bottom end of one side of the outer wall of the feed shell 4 through a square plate 5, and the magnetic separator is located below the feed shell 4; the magnetic separator is connected to the bottom end of the outer wall of the box body 1 ...

When the carbon nanotubes slide along the feed shell 4 into the quantitative grooves 14 on the cylinder 13, the rotating shaft 12 is driven to rotate by the motor 11, and the rotating shaft 12 drives the cylinder 13 to rotate, so that the rotation of the cylinder 13 drives a part of the carbon nanotubes in the quantitative grooves 14 to fall. When the carbon nanotubes fall, the magnetic impurities contained in the carbon nanotubes will be attracted and separated by the magnetic separator. Because a large number of carbon nanotubes are dropped one by one, the device can clean up the magnetic impurities in a large number of carbon nanotubes one by one, so that the device can attract and separate the magnetic impurities in the carbon nanotubes, and the effect is better, so that the subsequent purification or finished product quality of the carbon nanotubes is guaranteed.

[0030] One side of the outer wall of the square plate 5 is fixedly connected to one side of the outer wall of the feed shell 4; one end of the outer wall of a group of rotating rods 6 is rotatably connected to one side of the outer wall of the square plate 5, and the group of rotating rods 6 is distributed in a V shape; the outer side walls of a group of rotating rods 6 are fixedly connected with electromagnets 15, and the electromagnets 15 are ring-shaped; one end of the outer wall of a group of rotating rods 6 and the outer side wall of one end of the rotating shaft 12 located in the box body 1 are fixedly connected with a first gear 16, and a group of first gears 16 are meshed with each other. When the motor 11 drives the rotating shaft 12 to rotate, because one end of the outer wall of a group of rotating rods 6 and the outer side wall of one end of the rotating shaft 12 located in the box body 1 are fixedly connected with the first gear 16, and a group of first gears 16 are meshed with each other, the rotation of the rotating shaft 12 is achieved through the group of first gears 16. A group of rotating rods 6 are driven to rotate, so that the group of rotating rods 6 drive a group of electromagnets 15 to rotate, so that when the carbon nanotubes fall through the rotation of the cylinder 13, the group of electromagnets 15 can attract and separate the magnetic impurities contained in the carbon nanotubes, and because the group of rotating rods 6 in the device are distributed in a V shape, the group of electromagnets 15 are distributed in a V shape, so that when the carbon nanotubes fall, there are electromagnets 15 on both sides of the carbon nanotubes, and the carbon nanotubes need to be attracted and separated by a group of electromagnets 15 for multiple times, so that the device has better effect and efficiency in attracting and separating magnetic impurities in the carbon nanotubes, and the electromagnets 15 are kept rotating all the time, so that the outer surface of the electromagnets 15 can evenly absorb the magnetic impurities, so that the device can collect more magnetic impurities.

[0031] The outer wall of the box body 1 is fixedly connected with a medicine tube 19, and the medicine tube 19 is connected to the box body 1, and the medicine tube 19 matches the purification space 8; a pair of circular rods 20 are rotatably connected to the top of the outer wall of the partition 7; the outer wall tops of the pair of circular rods 20 are fixedly connected to the second bevel gear 21; the inner wall of the box body 1 is rotatably connected to the first rotating rod 22; the outer wall of the first rotating rod 22 and the outer wall of the end of the rotating shaft 12 located in the box body 1 are fixedly connected with a sprocket 23, and the pair of sprockets 23 are connected by a chain 24; the outer wall of the first rotating rod 22 is fixedly connected with a pair of third bevel gears 25, and the pair of third bevel gears 25 are respectively meshed with the pair of second bevel gears 21; the outer walls of the pair of circular rods 20 are fixedly connected with a group of rotating plates 26. When the magnetic impurities in the carbon nanotubes are attracted and separated by the electromagnet 15, the carbon nanotubes will continue to fall onto the partition 7. At this time, the external purification medicine storage container is connected to the medicine tube 19. , so that the purified agent flows into the purification space 8 in the box body 1 through the agent tube 19. At this time, the purified agent contacts with the carbon nanotubes. Because the outer wall of the first rotating rod 22 and the outer wall of one end of the rotating shaft 12 located in the box body 1 are fixedly connected with a sprocket 23, and a pair of sprockets 23 are connected by a chain 24, so that the rotating shaft 12 drives the electromagnet 15 to rotate while the first rotating rod 22 is driven to rotate through the sprocket 23 and the chain 24. The rotation of the first rotating rod 22 drives a pair of third bevel gears 25 to rotate. Because the pair of third bevel gears 25 are respectively meshed with the pair of second bevel gears 21, the third bevel gears 25 drive a pair of circular rods 20 to rotate through the second bevel gears 21, so that the pair of circular rods 20 drive a group of rotating plates 26 to rotate, so that the rotation of the rotating plates 26 stirs the purified agent, so that the carbon nanotubes can be more fully in contact with the purified agent, thereby improving the purification effect and efficiency of the carbon nanotubes.

[0032] A group of cleaning plates 17 are fixedly connected to the inner wall of the box body 1, and the group of cleaning plates 17 are inclined; one end of the outer wall of the group of cleaning plates 17 is in contact with the outer wall of a group of electromagnets 15; a group of impurity through grooves 18 are opened on the outer wall of the box body 1, and the group of impurity through grooves 18 are matched with a group of cleaning plates 17, and a group of cleaning plates 17 are fixedly connected to the inner wall of the box body 1, and the group of cleaning plates 17 are inclined; one end of the outer wall of the group of cleaning plates 17 is in contact with the outer wall of a group of electromagnets 15, so that after the magnetic impurities are adsorbed by the electromagnets 15, when the electromagnets 15 rotate to When the electromagnet 15 is at the cleaning plate 17, a part of the electromagnet 15 close to the cleaning plate 17 can be temporarily powered off, so that the magnetic impurities fall onto the cleaning plate 17, and then fall along the inclined surface of the cleaning plate 17 through the impurity through groove 18 to the outside of the box body 1 to be collected, so that the device can separate and collect the magnetic impurities at the same time, so that the electromagnet 15 is not easily adsorbed by a large number of magnetic impurities on its outer surface, resulting in a reduced adsorption effect, so that the adsorption capacity of the electromagnet 15 in the device is guaranteed, and the magnetic impurities can be separated, collected and cleaned at the same time.

[0033] The bottom ends of the outer walls of the pair of circular rods 20 penetrate the partition 7, and the bottom ends of the outer walls of the pair of circular rods 20 are rotatably connected to the bottom ends of the inner walls of the box body 1; the outer walls of one end of the pair of circular rods 20 located in the cleaning space 9 are fixedly connected with a pair of stirring plates 27, and the two pairs of stirring plates 27 are distributed in a T shape; the outer wall of the box body 1 is fixedly connected with a cleaning pipe 28, and the cleaning pipe 28 is connected to the box body 1; the cleaning pipe 28 matches the cleaning space 9, and when the carbon nanotubes are purified, the purification space 8 is cleaned through the reagent pipe 19. The purification agent is extracted, and then the second electrically controlled valve at the discharge port 10 is opened to allow the purified carbon nanotubes to fall from the discharge port 10 to the bottom of the inner wall of the box body 1. At this time, water is input into the cleaning space through the cleaning pipe 28 to contact the carbon nanotubes, and then the rotation of the circular rod 20 drives the two pairs of stirring plates 27 to rotate, so that the water can better clean the purified carbon nanotubes and the agents adhered to the outer surface of the carbon nanotubes are cleaned, so that the residue of the purification agent is not easy to affect the purity and quality of the carbon nanotubes.

[0034] A group of air holes 29 are provided at the bottom end of the outer wall of the stirring plate 27; a square groove 30 is provided at the top end of the inner wall of the group of air holes 29; a circular groove 31 is provided inside the pair of circular rods 20, and the pair of circular grooves 31 are respectively connected to the two pairs of square grooves 30; a hot air device 32 is fixedly connected to the outer wall of one end of the pair of circular rods 20 located in the cleaning space 9, and the pair of hot air devices 32 are respectively connected to the pair of circular grooves 31; a sealing block 33 is fixedly connected to one side of the inner wall of the square groove 30 through a first spring, and the sealing block 33 matches a group of air holes 29; the outer wall of the sealing block 33 is sealingly and slidably connected to the inner wall of the square groove 30; a connecting groove 34 is provided at the top end of the inner wall of the square groove 30, and a group of openings of the connecting groove 34 match a group of air holes 29 respectively. When the carbon nanotubes are cleaned, water is extracted through the cleaning pipe 28, and at this time the hot air device 32 blows hot air into the circular groove 31 In the embodiment, the hot air will enter a pair of square grooves 30 through the circular groove 31. Since the square grooves 30 are sealed by the sealing block 33, the wind force of the hot air will push the sealing block 33, so that the sealing block 33 drives the first spring to contract. At this time, a group of air holes 29 and the connecting groove 34 are exposed. At this time, the hot air will blow to other air holes 29 through the connecting groove 34 until the hot air is blown out from a group of air holes 29. When the hot air is blown out, the hot air will blow to the carbon nanotubes placed at the bottom end of the inner wall of the box body 1, and the stirring plate 27 is rotated all the time, so that the device can evenly blow the hot air to the carbon nanotubes, so that the carbon nanotubes can be evenly dried, making the cleaning and drying of the carbon nanotubes more convenient and quick. When the carbon nanotubes are cleaned, the air holes 29 are blocked by the sealing block 33, so that water will not enter the stirring plate 27. When the hot air device 32 is started, the sealing block 33 is blown, so that the air holes 29 are opened for drying.

[0035] A reciprocating rod 37 is rotatably connected to the edge of one side of the top end of the outer wall of the stirring plate 27 through a first square plate; a dispersion plate 38 is provided on the outer wall of the reciprocating rod 37, and the inner wall of the dispersion plate 38 contacts the outer wall of the stirring plate 27; one end of the outer wall of the two pairs of reciprocating rods 37 is fixedly connected to a fifth bevel gear 39; a pair of annular racks 40 are fixedly connected to the bottom end of the outer wall of the partition 7 through a group of connecting rods, and the pair of annular racks 40 are respectively meshed with the two pairs of fifth bevel gears 39. When the stirring plate 27 rotates with the circular rod 20, the rotation of the stirring rod will drive the reciprocating rod 37 and the fifth bevel gear 39 on the reciprocating rod 37 to rotate around the circular rod 20 through the first square plate. The bevel gears 39 mesh with each other and are stationary with the annular rack 40. The fifth bevel gear 39 rotates. When the fifth bevel gear 39 rotates, it rotates along the tooth grooves on the annular rack 40, thereby causing the fifth bevel gear 39 to drive the reciprocating rod 37 to rotate. The rotation of the reciprocating rod 37 drives the dispersion plate 38 to reciprocate on the stirring plate 27. When the stirring plate 27 rotates, the dispersion plate 38 moves back and forth on the stirring plate 27. The back and forth movement of the dispersion plate 38 flattens the carbon nanotubes accumulated at the bottom end of the inner wall of the casing 1 and disperses the carbon nanotubes. Although most of the impurities have been removed from the purified carbon nanotubes, the mutual attraction between the particles is significantly increased due to the nanoscale effect, and agglomerates are easily formed. This agglomeration phenomenon not only affects the performance of carbon nanotubes, but also limits their effective use in various applications. The present device can disperse the carbon nanotubes after purification, cleaning and drying, so that the carbon nanotubes are not easily entangled and adhered, thereby facilitating the subsequent processing of the carbon nanotubes. The rotation of the toggle rod 36, in conjunction with the movement of the dispersion plate 38 and the rotation of the stirring plate 27, can better disperse the carbon nanotubes, so that the dispersion efficiency and effect of the carbon nanotubes are better. The reciprocating motion of the dispersion plate 38 can also enhance the stirring effect of the stirring plate 27, so that when the carbon nanotubes are cleaned, the cleaning efficiency is further improved.

[0036] A square shell 35 is fixedly connected to the edge of one side of the bottom end of the outer wall of the stirring plate 27; a toggle rod 36 is fixedly connected to the top end of the inner wall of the square shell 35 through a second spring, and the toggle rod 36 is L-shaped, and the outer wall of one end of the toggle rod 36 is slidably connected to the inner wall of the square shell 35; the bottom end of the inner wall of the toggle rod 36 is arc-shaped, and the bottom end of the outer wall of the toggle rod 36 is in contact with the bottom end of the inner wall of the box body 1, and the square shell 35 is fixedly connected to the edge of one side of the bottom end of the outer wall of the stirring plate 27; the top end of the inner wall of the square shell 35 is fixedly connected to the inner wall of the square shell 35 through the second spring. The second spring is fixedly connected with a toggle rod 36, so that when the stirring rod rotates, the toggle rod 36 will be driven to rotate, so that when the air holes 29 on the stirring plate 27 are blown and dried, the rotation of the toggle rod 36 will toggle the carbon nanotubes accumulated at the bottom end of the inner wall of the box body 1, so that the carbon nanotubes can be turned over or moved under the toggle of the toggle rod 36, so that the entire outer surface of the carbon nanotubes can be dried by hot air, so that the drying of the carbon nanotubes is more uniform, thereby further improving the drying effect and efficiency of the carbon nanotubes. Example 2

[0037] See also Figure 6 - Figure 7 As shown, one end of the outer wall of the fifth bevel gear 39 is fixedly connected to a pair of circular shells 41 through a second square plate; the opposite sides of the inner walls of the pair of circular shells 41 are fixedly connected to a vibration rod 42 through a second spring, and the outer side walls of the pair of vibration rods 42 are respectively slidably connected to the inner side walls of the pair of circular shells 41; the opposite ends of the outer walls of the pair of vibration rods 42 are fixedly connected to a vibration ball 43, and the vibration ball 43 matches the stirring plate 27. When the reciprocating rod 37 rotates, the reciprocating rod 37 will drive the pair of circular shells 41 to rotate through the second square plate, so that the circular shells 41 drives the vibration rod 42 and the vibration ball 43 to rotate, so that the vibration ball 43 hits the outer wall of the stirring plate 27 under the action of the elastic force and rotational force of the second spring, so that the stirring plate 27 vibrates, and then the vibration force is transmitted to the toggle rod 36 and the dispersion plate 38 through the stirring plate 27, so that when the dispersion plate 38 and the toggle rod 36 disperse the carbon nanotubes, the vibration force will be transmitted to the carbon nanotubes, and the bonded carbon nanotubes will be vibrated and dispersed, so that the device can further improve the dispersion efficiency and effect of the carbon nanotubes through the vibration force.

[0038] When the present invention is in use, by putting carbon nanotubes into the feed shell 4, when the carbon nanotubes slide down the feed shell 4 into the quantitative groove 14 on the cylinder 13, the motor 11 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the cylinder 13 to rotate, so that the rotation of the cylinder 13 drives a part of the carbon nanotubes in the quantitative groove 14 to fall. Because one end of the outer wall of a group of rotating rods 6 and the outer side wall of one end of the rotating shaft 12 located in the box body 1 are fixedly connected with the first gear 16, and the group of first gears 16 are meshed with each other, the rotation of the rotating shaft 12 drives the group of rotating rods 6 to rotate through the group of first gears 16, so that the group of rotating rods 6 drives the group of electromagnets 15 to rotate, so that when the carbon nanotubes fall through the rotation of the cylinder 13, the group of electromagnets 15 can The magnetic impurities contained in the carbon nanotubes are attracted and separated. Because a group of rotating rods 6 in the device are distributed in a V shape, a group of electromagnets 15 are distributed in a V shape, so that when the carbon nanotubes fall, there are electromagnets 15 on both sides of the carbon nanotubes, and the carbon nanotubes need to be attracted and separated by a group of electromagnets 15 for multiple times, so that the device has better effect and efficiency in attracting and separating magnetic impurities in the carbon nanotubes. The electromagnets 15 are kept rotating all the time, so that the outer surface of the electromagnets 15 can uniformly absorb the magnetic impurities, so that the device can collect more magnetic impurities. A large number of carbon nanotubes are divided into portions and fall through the rotation of the cylinder 13, so that the device can separate a large number of magnetic impurities in the carbon nanotubes in part and in part. The device can clean the magnetic impurities in the carbon nanotubes by suction, so that the effect of the device on attracting and separating the magnetic impurities in the carbon nanotubes is better, so that the subsequent purification or quality of the carbon nanotubes is guaranteed, and a group of cleaning plates 17 are fixedly connected to the inner wall of the box body 1, and the group of cleaning plates 17 are inclined; one end of the outer wall of a group of cleaning plates 17 is in contact with the outer wall of a group of electromagnets 15, so that after the magnetic impurities are adsorbed by the electromagnets 15, when the electromagnets 15 rotate to the cleaning plates 17, the electromagnets 15 and the part of the electromagnets 15 close to the cleaning plates 17 can be temporarily powered off, so that the magnetic impurities fall onto the cleaning plates 17, and then fall along the inclined surface of the cleaning plates 17 through the impurity slots 18 to the outside of the box body 1 to be collected, so that the device can separate the magnetic impurities while Magnetic impurities are collected, so that the electromagnet 15 is not easy to reduce the adsorption effect due to the large amount of magnetic impurities adsorbed on its outer surface, so that the adsorption capacity of the electromagnet 15 in the device is guaranteed, and the magnetic impurities can be separated, collected and cleaned at the same time. When the magnetic impurities in the carbon nanotubes are attracted and separated by the electromagnet 15, the carbon nanotubes will continue to fall onto the partition 7. At this time, the external purification agent storage container is connected to the agent tube 19, so that the purified agent flows into the purification space 8 in the box body 1 through the agent tube 19. At this time, the purified agent and the carbon nanotubes are in contact with each other. Because the outer side wall of the first rotating rod 22 and the outer side wall of one end of the rotating shaft 12 located in the box body 1 are fixedly connected with a sprocket 23, and a pair of sprockets 23 are connected by a chain 24,When the rotating shaft 12 drives the electromagnet 15 to rotate, the first rotating rod 22 is driven to rotate through the sprocket 23 and the chain 24. The rotation of the first rotating rod 22 drives a pair of third bevel gears 25 to rotate. Because the pair of third bevel gears 25 are respectively meshed with the pair of second bevel gears 21, the third bevel gears 25 drive a pair of circular rods 20 to rotate through the second bevel gears 21, so that the pair of circular rods 20 drive a group of rotating plates 26 to rotate. The rotation of the rotating plates 26 stirs the purification agent, so that the carbon nanotubes can be more fully contacted with the purification agent, thereby improving the purification effect and efficiency of the carbon nanotubes. When the purification of the carbon nanotubes is completed, the purification agent in the purification space 8 is extracted through the agent tube 19, and then the second electrically controlled valve at the discharge port 10 is opened to make The purified carbon nanotubes fall from the discharge port 10 to the bottom end of the inner wall of the box body 1. At this time, water is input into the cleaning space through the cleaning pipe 28 to contact the carbon nanotubes, and then the rotation of the circular rod 20 drives the two pairs of stirring plates 27 to rotate, so that the water can better clean the purified carbon nanotubes, so that the reagents adhered to the outer surface of the carbon nanotubes are cleaned, so that the residues of the purification reagents are not easy to affect the purity and quality of the carbon nanotubes. When the carbon nanotubes are cleaned, water is extracted through the cleaning pipe 28. At this time, the hot air device 32 blows hot air into the circular groove 31, and the hot air will pass through the circular groove 31 into a pair of square grooves 30. Because the square groove 30 is sealed by the sealing block 33, the wind force of the hot air will push the sealing block 33, so that the sealing block 33 drives the first spring to contract. At this time, a group of air holes 29 and the connecting groove 34 are exposed, and the hot air will be blown to other air holes 29 through the connecting groove 34 until the hot air is blown out from a group of air holes 29. When the hot air is blown out, the hot air will blow to the carbon nanotubes placed at the bottom end of the inner wall of the box body 1, and the stirring plate 27 is rotated all the time, so that the device can evenly blow the hot air to the carbon nanotubes, so that the carbon nanotubes can be evenly dried, making the cleaning and drying of the carbon nanotubes more convenient and quick. When the carbon nanotubes are cleaned, the air holes 29 are blocked by the sealing block 33, so that water will not enter the stirring plate 27. When the hot air device 32 is started, the sealing block 33 is blown, so that the air holes 29 are opened for blowing and drying, and the square shell 3 is fixedly connected to the edge of the bottom end of the outer wall of the stirring plate 27. 5; The top of the inner wall of the square shell 35 is fixedly connected with a toggle rod 36 through a second spring, so that when the stirring rod rotates, the toggle rod 36 is driven to rotate, so that when the air holes 29 on the stirring plate 27 are blown and dried, the rotation of the toggle rod 36 will toggle the carbon nanotubes accumulated at the bottom end of the inner wall of the box body 1, so that the carbon nanotubes can be turned over or moved under the toggle of the toggle rod 36, so that the entire outer surface of the carbon nanotubes can be dried by hot air, so that the drying of the carbon nanotubes is more uniform, so that the drying effect and efficiency of the carbon nanotubes are further improved, and when the stirring plate 27 rotates with the circular rod 20, the rotation of the stirring rod will drive the reciprocating rod 37 and the fifth bevel gear 39 on the reciprocating rod 37 to rotate around the circular rod 20 through the first square plate,Because a pair of annular racks 40 are respectively meshed with two pairs of fifth bevel gears 39, and the annular rack 40 is stationary, and the fifth bevel gear 39 is in motion and rotation, when the fifth bevel gear 39 rotates, it will rotate along the tooth grooves on the annular rack 40, so that the fifth bevel gear 39 drives the reciprocating rod 37 to rotate, and the rotation of the reciprocating rod 37 will drive the dispersion plate 38 to reciprocate on the stirring plate 27, so that when the stirring plate 27 rotates, the dispersion plate 38 moves back and forth on the stirring plate 27, and the back and forth movement of the dispersion plate 38 will flatten the carbon nanotubes accumulated at the bottom end of the inner wall of the box body 1, so that the carbon nanotubes are dispersed. Although most of the impurities have been removed from the purified carbon nanotubes, due to their nanoscale effect, the mutual attraction between the particles is significantly increased, and agglomerates are easily formed. This agglomeration phenomenon not only affects the performance of carbon nanotubes, but also limits their effective use in various applications. The present device can disperse the carbon nanotubes after purification, cleaning and drying, so that the carbon nanotubes are not easily entangled and adhered, thereby facilitating the subsequent processing of the carbon nanotubes. The rotation of the toggle rod 36, in conjunction with the movement of the dispersion plate 38 and the rotation of the stirring plate 27, can better disperse the carbon nanotubes, so that the dispersion efficiency and effect of the carbon nanotubes are better. The reciprocating motion of the dispersion plate 38 can also enhance the stirring effect of the stirring plate 27, so that when the carbon nanotubes are cleaned, the cleaning efficiency is further improved. When the reciprocating rod 37 rotates, the reciprocating rod 37 will drive a pair of circular shells 41 to rotate through the second square plate, so that the circular shells 41 drives the vibration rod 42 and the vibration ball 43 to rotate, so that the vibration ball 43 hits the outer wall of the stirring plate 27 under the elastic force and rotational force of the second spring, causing the stirring plate 27 to vibrate, and then the vibration force is transmitted to the toggle rod 36 and the dispersion plate 38 through the stirring plate 27, so that when the dispersion plate 38 and the toggle rod 36 disperse the carbon nanotubes, the vibration force will be transmitted to the carbon nanotubes, and the bonded carbon nanotubes will be vibrated and dispersed, so that the device can further improve the dispersion efficiency and effect of the carbon nanotubes through the vibration force. After the separation, purification, cleaning, drying, dispersion and other processes of the carbon nanotubes are completed, the first electric control valve at the discharge pipe 3 is opened, so that the carbon nanotubes fall out of the box 1 through the discharge pipe 3 and are collected.
