[0021] Furthermore, the vacuum box includes a box body, which is arranged on the frame, and a box cover is detachably provided on the top surface of the box body.

[0023] Furthermore, the vacuum generating member includes a first extension plate, which is provided on the outer surface of the vacuum box. A vacuum pump is provided on the first extension plate, and the vacuum pump is connected to the interior of the vacuum box.

[0025] The ash extraction component includes an exhaust fan, which is arranged on the frame and connected to the vacuum box; a second solenoid valve, which is connected to the exhaust fan and the vacuum box, and the exhaust fan is provided with an external pipe.

[0026] Therefore, the present invention provides the following effects and / or advantages:

[0027] 1) The vacuum generating element is used to evacuate the vacuum box to a predetermined vacuum, and the inert gas generating element is used to input a predetermined amount of inert gas into the vacuum box after the vacuum generating element evacuates the vacuum box to the predetermined vacuum.

[0028] The isolating drive component is used to drive the graphite cathode column to rotate to the next movable disk at predetermined intervals after the inert gas generating component inputs a predetermined amount of inert gas into the vacuum box, until it rotates to each movable disk, so that the multiple graphite anode columns on each movable disk successively cooperate with the graphite cathode column, thereby generating a sufficient amount of a mixture containing fullerenes in a limited space.

[0029] The front-end driving member is used to input a predetermined amount of inert gas into the vacuum box through the inert gas generating member and drive several graphite anode columns on the movable disk to cooperate with the graphite cathode column in succession before the graphite cathode column rotates to the next movable disk.

[0030] Each graphite anode column and graphite cathode column are coordinated as follows: the graphite cathode column and the graphite anode column are fitted together and energized at the same time to generate an electric arc to cause the graphite anode column to evaporate and produce a mixture containing fullerenes; after a predetermined time has passed since the graphite cathode column and the graphite anode column were energized, the driving compensation drive component drives the graphite anode column away from the graphite cathode column until the distance between the graphite anode column and the graphite cathode column reaches a predetermined value to prevent a short circuit, thereby ensuring that the graphite anode column continues to evaporate and continuously produces a mixture containing fullerenes; when the distance between the graphite anode column and the graphite cathode column reaches a predetermined value and shortens as the graphite anode column continues to evaporate, the driving component gradually drives the graphite anode column close to the graphite cathode column to maintain the distance between the graphite anode column and the graphite cathode column at a predetermined value, thereby preventing the distance between the graphite anode column and the graphite cathode column from exceeding the predetermined value and causing the graphite anode column to be unable to stably and effectively evaporate.

[0031] The driving compensation driving member is used to drive the graphite anode column close to the graphite cathode column when the gradual retraction driving member fails to effectively maintain the distance between the graphite anode column and the graphite cathode column, so as to perform distance compensation, thereby ensuring that the distance between the graphite anode column and the graphite cathode column is a predetermined value, ensuring that the graphite anode column can stably and effectively evaporate.

[0032] The limiting guide sleeve is used to support and limit the graphite anode column when the graphite anode column is not matched with the graphite cathode column, so that the graphite anode column is stable in the limiting guide sleeve, thereby preventing the graphite anode column from being unable to align and fit with the graphite cathode column; the limiting guide sleeve is used to guide the movement of the graphite anode column during the period when the graphite anode column is matched with the graphite cathode column and the gradually retracting driving member drives the graphite anode column close to the graphite cathode column, so as to prevent the graphite anode column from deflecting during movement, thereby preventing the graphite anode column from being unable to align and fit with the graphite cathode column.

[0033] The soot extraction member is used to extract the mixture containing fullerenes in the vacuum box out of the vacuum box after the several graphite anode columns on each movable disk are matched with the graphite cathode columns in succession and driven.

[0034] In summary: the graphite cathode column can be rotated to the next predetermined position at predetermined intervals until it reaches each predetermined position; several graphite anode columns at each predetermined position can be successively matched with the graphite cathode column to produce a sufficient amount of a mixture containing fullerenes in a limited space; short circuits can be prevented when the graphite anode column and the graphite cathode column are matched, thereby ensuring that the graphite anode column continues to evaporate and continuously produces a mixture containing fullerenes; and the graphite anode column can be stably and effectively evaporated when the graphite anode column and the graphite cathode column are matched.

[0035] 2) The supporting and pushing plate is used to block the mixture containing fullerenes generated during the period when the retracting driving member drives the graphite anode column close to the graphite cathode column, so as to prevent the generated mixture containing fullerenes from adhering to the compression spring, thereby extending the service life of the compression spring and ensuring the use effect of the compression spring; the supporting and pushing plate is used to push the mixture containing fullerenes adhering to the inner wall of the bearing guide sleeve to the outside of the bearing guide sleeve during the period when the retracting driving member drives the graphite anode column close to the graphite cathode column, so as to prevent the mixture containing fullerenes from accumulating in the bearing guide sleeve, thereby preventing the mixture containing fullerenes from adhering to a new graphite anode column.

[0036] 3) The heat-resistant sealing layer is used to prevent the heat generated during the mating of the graphite anode column and the graphite cathode column and the mixture containing fullerenes from entering the connection box through the connection between the linkage rod and the vacuum box, to prevent the second rotating motor from being damaged, which would cause the other graphite anode columns on the movable disk to be unable to mated with the graphite cathode column one after another, and to prevent the telescopic motor from being damaged, which would cause the driving member to be unable to drive the graphite anode column away from the graphite cathode column after a predetermined time has passed since the graphite cathode column and the graphite anode column were energized.

[0037] 4) The box cover is used to be driven to separate from the box body after the soot extraction member extracts the fullerene-containing mixture from the vacuum box, so that a new graphite anode column can be loaded into the limiting guide sleeve; the box cover is used to be driven to be installed at a predetermined position on the box body after the new graphite anode column is loaded into the limiting guide sleeve, so that the graphite cathode column is aligned and fits with the uppermost graphite anode column of one of the movable disks.

[0038] 5) During the period when the graphite anode columns on the movable plate are successively matched with the graphite cathode columns, the temperature in the vacuum box can be reduced by the cooperation of the cooling limit seat, the cooling channel, the first hollow connecting rod, the second hollow connecting rod, the cooling box, the liquid pump, the inlet pipe, and the return pipe, thereby facilitating the production of a mixture containing fullerenes;

[0039] The cooling limit seat is used to prevent the formation of a mixture containing fullerenes near other movable disks when several graphite anode columns on the movable disk are successively matched with graphite cathode columns. It can limit most of the generated mixture containing fullerenes near the current movable disk, preventing the graphite anode columns on other movable disks from being covered with too much mixture containing fullerenes, which would prevent the graphite anode columns from generating arcs and evaporating.

The purpose and other advantages of the present invention are realized and obtained by the structures particularly pointed out in the description and the drawings.

[0056] The front-end driving member is used to input a predetermined amount of inert gas into the vacuum box 2 through the inert gas generating member and drive the multiple graphite anode columns 5 on the movable disk 3 to successively cooperate with the graphite cathode columns 6 before the graphite cathode column 6 rotates to the next movable disk 3;

[0057] Each graphite anode column 5 and graphite cathode column 6 cooperate as follows: the graphite cathode column 6 and the graphite anode column 5 are attached to each other and energized at the same time to generate an electric arc to cause the graphite anode column 5 to evaporate and produce a mixture containing fullerenes; after a predetermined time has passed since the graphite cathode column 6 and the graphite anode column 5 were energized, the driving compensation drive member drives the graphite anode column 5 away from the graphite cathode column 6 until the distance between the graphite anode column 5 and the graphite cathode column 6 reaches a predetermined value to prevent a short circuit, thereby ensuring that the graphite anode column 5 continues to evaporate and continuously produces a mixture containing fullerenes; when the distance between the graphite anode column 5 and the graphite cathode column 6 reaches a predetermined value and shortens as the graphite anode column 5 continues to evaporate, the driving member gradually drives the graphite anode column 5 closer to the graphite cathode column 6 to maintain the distance between the graphite anode column 5 and the graphite cathode column 6 at the predetermined value, thereby preventing the distance between the graphite anode column 5 and the graphite cathode column 6 from exceeding the predetermined value and causing the graphite anode column 5 to be unable to stably and effectively evaporate;

[0058] The driving compensation driving member is used to drive the graphite anode column 5 closer to the graphite cathode column 6 when the gradual retraction driving member fails to effectively maintain the distance between the graphite anode column 5 and the graphite cathode column 6, so as to perform distance compensation, thereby ensuring that the distance between the graphite anode column 5 and the graphite cathode column 6 is a predetermined value, ensuring that the graphite anode column 5 can stably and effectively evaporate;

[0059] The limiting guide sleeve 4 is used to support and limit the graphite anode column 5 when the graphite anode column 5 is not matched with the graphite cathode column 6, so that the graphite anode column 5 is stable in the limiting guide sleeve 4, thereby preventing the graphite anode column 5 from being unable to align and fit with the graphite cathode column 6; the limiting guide sleeve 4 is used to guide the movement of the graphite anode column 5 during the period when the graphite anode column 5 is matched with the graphite cathode column 6 and the gradually retracting driving member drives the graphite anode column 5 close to the graphite cathode column 6, so as to prevent the graphite anode column 5 from deflecting during movement, thereby preventing the graphite anode column 5 from being unable to align and fit with the graphite cathode column 6;
