Abstract

The invention discloses a grinding, transporting and sealing device for carbon nanotubes, and belongs to the technical field of chemical equipment. The grinding, transporting and sealing device for the carbon nanotubes comprises a constant pressure mechanism, a first cooling mechanism, a second cooling mechanism and a grinding tank, wherein the grinding tank is a double-layer tank body; the constant pressure mechanism comprises a gas storage tank which is communicated with the grinding tank; the first cooling mechanism comprises a cooling coil, and the cooling coil is located in the grinding tank; the second cooling mechanism comprises a cooling tank; the cooling tank is communicated with the interlayer of the double-layer tank body; and a grinding device is arranged in the grinding tank. According to the invention, a dual-cooling mode is used, so that the influence on the quality caused by overhigh temperature during grinding and stirring of the carbon nanotubes is avoided; moreover, the sealing performance is good, the interior of the device can be kept in a constant-pressure state all the time, the quality of the carbon nanotube slurry is ensured, and the effective utilization rate of the carbon nanotube slurry is improved.

Description

technical field [0001] The invention relates to a grinding, transportation and sealing device for carbon nanotubes, which belongs to the technical field of chemical equipment. Background technique [0002] Carbon nanotubes, also known as bucky tubes, are one-dimensional quantum materials whose radial dimensions are on the order of nanometers and axial dimensions are on the order of microns, and both ends of the tube are basically sealed. Carbon nanotubes can be regarded as curled graphene sheets, so according to the number of layers of graphene sheets can be divided into: single-walled carbon nanotubes (or single-walled carbon nanotubes, Single-walled Carbonnanotubes, SWCNTs) and multi- Walled carbon nanotubes (or multi-layer carbon nanotubes, Multi-walled Carbon nanotubes, MWCNTs), when multi-walled tubes start to form, it is easy to become a trap center between layers and trap various defects, so multi-walled tubes The wall of the pipe is usually covered with small hole-l...

AI Technical Summary

Problems solved by technology

[0004] Based on the characteristics of carbon nanotubes, carbon nanotubes often agglomerate and cannot be uniformly dispersed in the carbon nanotube slurry. When the tube slurry is in the slurry, due to the long-term operation of the device, the parts are aging and damaged, and the sealing performance is poor. It cannot ensure that the device is in a constant pressure state when grinding and stirring carbon nanotubes, which will reduce the quality of the carbon nanotube slurry; and when the device is grinding and stirring, the temperature is high. It will lead to the deterioration of heat-sensitive materials, which will seriously affect the quality of carbon nanotube slurry
