Ultrahigh-temperature continuous carbon nanotube purification equipment

Abstract

The invention relates to the technical field of carbon nanotube equipment, and especially relates to ultrahigh-temperature continuous carbon nanotube purification equipment. An iodine vapor feeding pipe and a carbon nanotube feeding pipe are connected with a mixer, the mixer is connected with a distributor, the distributor is connected with a reaction kettle, the reaction kettle is connected with a tail gas treatment device, and the reaction kettle is provided with a heating device and a stirring shaft. The stirring shaft is provided with a cleaning device, the outer wall of a sliding sleeve is provided with two spiral grooves, the spiral grooves are in sliding connection with a mounting sleeve, the reaction kettle is provided with a sliding rod, the sliding rod is in sliding connection with a mounting sleeve, the mounting sleeve is provided with a cleaning support, the cleaning support is provided with a cleaning scraper, and the cleaning scraper abuts against the heating device. The stirring shaft rotates to drive the sliding sleeve to rotate, the mounting sleeve is forced to slide up and down along the sliding rod, and then the cleaning support and the cleaning scraper are driven to move up and down. Impurities on the outer wall of a protective cover are scraped off through the cleaning scraper. The heat transfer efficiency of the heating pipe is prevented from being influenced by impurities attached outside the protective cover, so that the energy loss of the equipment is increased.

Description

technical field [0001] The invention relates to the technical field of ultrasonic seams, in particular to ultra-high temperature continuous carbon nanotube purification equipment. Background technique [0002] Carbon nanotubes have attracted people's attention due to their unique structural characteristics, singular physical and chemical properties, and potential application value in the future high-tech field. They have become research frontiers and hot spots in the fields of physics, chemistry, biology, and materials. Devices, catalyst supports, electrochemical materials, composite materials and many other fields have broad application prospects. [0003] For example, Chinese patent application No. CN201920344690.0 discloses a high-temperature continuous purification equipment for carbon nanotubes, including a feeding tank, a high-temperature purification tank and a product cooling tank, and the high-temperature purification tank is arranged between the feeding tank and th...

Problems solved by technology

[0004] However, there are still problems in the above patent. For example, the high-temperature purification tank of this patent is not easy to clean. After long-term use, impurities will adhere to the inner wall of the tank, which in turn affects the heat conduction of the heating tube and increases energy loss.
