Description

Technical Field

[0001] This utility model relates to the field of carbon nanotube preparation, and in particular to a backup purification device for carbon nanotubes. Background Technology

[0002] Carbon nanotubes, also known as buckytubes, are one-dimensional quantum materials with a unique structure (radial dimensions on the nanometer scale, axial dimensions on the micrometer scale, and both ends of the tube are basically sealed). Carbon nanotubes are mainly composed of several to dozens of layers of coaxial cylindrical tubes with carbon atoms arranged in a hexagonal pattern. As a one-dimensional nanomaterial, carbon nanotubes are lightweight, have a perfectly connected hexagonal structure, and possess many extraordinary mechanical, electrical, and chemical properties. In recent years, with the deepening of research on carbon nanotubes and nanomaterials, their broad application prospects have been continuously revealed.

[0003] A cyclone separator is a device used for separating gas-solid or liquid-solid systems. Its working principle is based on the rotational motion caused by the tangential introduction of airflow, which throws solid particles or liquid droplets with large inertial centrifugal force toward the outer wall surface and separates them. The cyclone separator is a dry gas-solid separation device that uses the centrifugal force generated when the gas-solid mixture rotates at high speed to separate dust from the airflow. Because the centrifugal force on the particles is much greater than gravity and inertial force, the separation efficiency is high.

[0004] Because carbon nanotubes often contain many impurities during the production process, but high purity is required for their application, carbon nanotubes can be purified by removing impurities under high temperature and vacuum conditions to achieve high purity.

[0005] The prior art patent application with publication number CN215540741U describes a process where materials are added into the vessel through the feed inlet. An external power source is then connected to activate the heating structure within the vessel, raising the temperature of the materials. During this process, a negative pressure device within the frame operates, creating negative pressure within the negative pressure pipe. This negative pressure draws in vaporized impurities and transfers them to the outlet pipe. The mixed airflow in the outlet pipe enters the separator through the air inlet. The separator then discharges the air free of solids through the air outlet, while the accidentally drawn-in materials fall through the dust outlet and back into the feed inlet via a connecting pipe, eventually returning to the vessel. The purified material is discharged from the outlet. This design is compact, convenient to use, and facilitates material purification while preventing waste, thus meeting the needs of users.

[0006] However, when using current purification equipment, multiple cooling tubes are installed at the bottom of the vessel to cool the raw materials inside. However, simply installing cooling tubes at the bottom of the vessel results in only the raw materials near the bottom of the vessel being cooled, while the raw materials far from the bottom of the vessel cannot be cooled evenly.

[0007] Therefore, it is necessary to provide a backup purification device for carbon nanotubes to solve the above-mentioned technical problems. Utility Model Content
