Description
One, technical field
The utility model belongs to the arc technology field, particularly a kind of carbon nanotube arc discharge device free to rotate.
Two, background technology
Carbon nanotube is a kind of broad-spectrum novel nano-material with good physical and chemical property, the preparation carbon nanotube mainly contains arc process, catalytic pyrolysis method, chemical Vapor deposition process (CVD), laser evaporation method at present, wherein arc process is a kind of important method of preparation carbon nano-tube material, and the carbon nanotube degree of graphitization height of this method preparation, physical property is best, generally with the carbon nanotube performance of this method preparation nominal value as this material.At present; when using preparing carbon nano tube by arc process; exist output few, can not non-stop run etc. shortcoming; promptly the quality of each preparation is all less than a gram; carbon nanotube of every preparation all will carry out electrode and install, vacuumizes, fills trivial step such as shielding gas; be unfavorable for like this being unfavorable for reducing preparation cost at industrial a large amount of preparation carbon nanotubes, can't satisfy growing, to the market requirement of carbon nanotube.
Three, summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of arc discharge device that can improve the preparation carbon nanotube of carbon pipe output, strong operability simple in structure is provided.
For achieving the above object, the solution that the utility model adopts is: it comprises anode carrier, the cathode anchor that is arranged in the vacuum chamber, anode carrier links by anode transfer arm and anode, cathode anchor is provided with disk-shaped cathode, is characterized in being respectively arranged with in the lower end of anode carrier and cathode anchor anode turning handle and negative electrode turning handle.

The utility model is simple in structure, and is safe and reliable, can realize semi continuous work, and therefore the carbon nanotube yield height of preparation, can be used for arc process and prepare carbon nanotube in a large number.
Four, description of drawings
Accompanying drawing is the structural representation of an embodiment of the utility model.
Five, embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are described in further detail.
Referring to accompanying drawing, the utility model is anode carrier 2, cathode anchor 6 are inserted from the chassis of vacuum chamber 1 and to be fixed in the vacuum chamber 1, and anode props up and adds 2 and can rotate in vacuum chamber 1 with cathode anchor 6, anode carrier 2, cathode anchor 6 are connected the arc power output terminal by lead, load onto anode transfer arm 3 and anode 4 in anode carrier 2 upper ends, the upper end of cathode anchor 6 is provided with disk-shaped cathode 5.Be respectively arranged with anode turning handle 9 and water-cooled tube 7 in the lower end of anode carrier 2, be respectively arranged with negative electrode turning handle 8 and water-cooled tube 7 in the lower end of cathode anchor 6, water-cooled tube 7 can make electrode unlikely in the course of the work overheated, helps the generation of carbon nanotube.This device is regulated the position of anode 4, disk-shaped cathode 5 by the position of adjusting anode turning handle 9 and negative electrode turning handle 8, make the center of anode 4 axis near disk-shaped cathode 5, anode 4 is 1～2 millimeter with the gap of disk-shaped cathode 5, and anode carrier 2 and cathode anchor 6 also can be controlled the rotation of anode 4 and disk-shaped cathode 5 by motor.
Principle of work of the present utility model is as follows:
Vacuum chamber is vacuumized, open arc power after filling shielding gas, make the starting the arc between anode 4, the disk-shaped cathode 5, discharge, can form the column shaped deposits of carbon nanotubess on disk-shaped cathode 5 surfaces in about 5～10 minutes.The breaking arc power supply, discharge is suspended, rotate the negative electrode turning handle 8 of cathode anchor 6 belows, make disk-shaped cathode 5 rotate an angle, open arc power, restart discharge, after discharge after a while, can form the column shaped deposit of a new carbon nanotube again on disk-shaped cathode 5 surfaces, the settling that it and upper strata form is adjacent.Method has been discharged at every turn like this, makes disk-shaped cathode 5 rotate discharge again after the angle, just can be at the column shaped deposits of a series of carbon nanotubes of disk-shaped cathode 5 surface formation, and they are positioned on the disk-shaped cathode 5 pericentral circumference.After all being covered with the carbon nanotube column shaped deposit on the circumference, anode turning handle 9 below the rotation anode carrier 2, make anode transfer arm 3 turn over an angle, this moment, column anode 2 just was transformed on the another one concentric circumferences, open arc power again, restart discharge, after discharge after a while, can form the column shaped deposit of a new carbon nanotube again on disk-shaped cathode 5 surfaces.Behind the carbon nanotube column shaped deposit that has been covered with the formation of discharge back on the disk-shaped cathode 5, can stop preparation, disk-shaped cathode 5 is taken out in the vacuum system venting, and top carbon nanotube column shaped deposit is scraped, and just can obtain a large amount of carbon nanotube settlings.
