AI Technical Summary
Technical Problem
In the process of preparing single-walled carbon nanotubes by plasma arc method, material entanglement is prone to occur on the cathode graphite rod, which affects the generation and collection of carbon nanotubes.
Method used
A conveying channel and a diversion port are set on the graphite cathode rod. The diversion channel is used to reverse the airflow and blow away the material wrapped around the cathode, so as to avoid the material entanglement phenomenon and maintain the normal operation of plasma discharge.
Benefits of technology
This technology enables continuous production of single-walled carbon nanotubes without affecting plasma discharge, thus avoiding cathode entanglement and improving yield and purity.

Abstract
The utility model provides an electrode and a device for preparing a single-walled carbon nanotube by a plasma arc method, and relates to the technical field of carbon nanotubes. Specifically, the electrode comprises a graphite cathode rod, the graphite cathode rod is provided with a conveying channel in the length direction of the graphite cathode rod, and the two ends of the graphite cathode rod are provided with an air inlet and an air outlet which are communicated with the conveying channel respectively; a plurality of shunting ports are formed in positions, close to the air outlet, of the side surface of the graphite cathode rod; and the shunting ports are communicated with the conveying channel through shunting channels. According to the graphite cathode based on a specific structure, the material winding phenomenon in the preparation process of the carbon nanotube can be avoided under the conditions that external force is not applied and plasma discharge is not influenced, the single-walled carbon nanotube with high content and high yield is obtained, and the graphite cathode has a good application prospect.
