Description

Technical Field

[0001] The utility model relates to the technical field of carbon nanotubes, and specifically relates to an improved carbon nanotube dispersion device. Background Art

[0002] Carbon nanotubes, also known as buckytubes, are one-dimensional quantum materials with a special structure. Their radial size is on the nanometer scale, the axial size is on the micrometer scale, and both ends of the tube are basically sealed. Carbon nanotubes are mainly composed of several to dozens of coaxial circular tubes formed by carbon atoms arranged in a hexagonal pattern. And according to the different orientations of the carbon hexagons along the axis, they can be divided into three types: zigzag, armchair, and helical. Among them, the helical carbon nanotubes have chirality, while the zigzag and armchair carbon nanotubes do not have chirality. Therefore, carbon nanotubes need to be processed by a carbon nanotube dispersion device with a heating device.

[0034] Working principle:

[0035] When it is necessary to heat the carbon nanotubes:

[0036] The operator places the carbon nanotubes in the net cage 4, pours water into the first box body 2, and starts two heating blocks 3 (such as Figure 2 ), the heating blocks 3 heat the water in the first box body 2, thereby heating the carbon nanotubes by water bath. After the carbon nanotubes are heated, the two heating blocks 3 are turned off.

[0037] Drying the carbon nanotubes:

[0038] Open the solenoid valve on the first discharge pipe 12, and the carbon nanotubes fall into the second box body 5 through the first discharge pipe 12. Open the spray head 711, and the nitrogen in the nitrogen source is sprayed out from the spray head 711 through the rigid pipe 710. Connect the external power supply of the first motor 701 and start the first motor 701. The output shaft of the first motor 701 rotates to drive the first connecting rod 702 to rotate (such as Figure 6 ), the rotation of the first connecting rod 702 drives the protrusion at the left end of the second connecting rod 703 to slide in the groove 704, the sliding of the groove 704 drives the sector slideway 705 to rotate in the first housing 6, the sliding of the sector slideway 705 drives the sector rack 713 to slide, the sliding of the sector rack 713 drives the first gear 706 to rotate, the rotation of the first gear 706 drives the threaded rod 707 to rotate, the rotation of the threaded rod 707 drives the nut 708 to slide in the first housing 6, the sliding of the nut 708 drives the rigid pipe 710 to move, the movement of the rigid pipe 710 drives the spray head 711 to move, the movement of the rigid pipe 710 drives the baffle 712 to move, and the baffle 712 can block the gap between the rigid pipe 710 and the chute of the first housing 6 to prevent the carbon nanotubes from entering the first housing 6 when the spray head 711 sprays nitrogen.

After the carbon nanotubes are dried, turn off the first motor 701 and close the spray head 711.

[0039] When the carbon nanotubes need to be dispersed:

[0040] Open the solenoid valve of the second discharge pipe 13, and the dried carbon nanotubes enter the third box body 10 through the second discharge pipe 13. Pour an appropriate amount of carbon nanotube dispersion liquid into the third box body 10. Connect the external power supply of the third motor 909 and start the third motor 909.

[0041] Cleaning the third box body 10:

[0042] Connect the external power supply of the second motor 901 and start the second motor 901. The output shaft of the second motor 901 rotates to drive the second gear 902 to rotate (such asFigure 4 ) When the second gear 902 rotates, it drives the third gear 903 to rotate around the second gear 902 within the annular rack 904.

The sliding of the chute 907 drives the third housing 908 to move. The movement of the third housing 908 drives the stirring rod 910 to move. When the stirring rod 910 moves to the uppermost position, the second motor 901 is turned off to clean the residue of the carbon nanotubes in the third box body 10. After the cleaning is completed, the second motor 901 is started. The second motor 901 moves the stirring rod 910 in the direction opposite to the above-mentioned movement direction. The second motor 901 moves the stirring rod 910 back to its original position in the above-mentioned manner, which is convenient for the next use. The second motor 901 is turned off, and the processing process of the carbon nanotube dispersion device with a heating device is completed.
