Fullerene has excellent electrical, optical, and mechanical properties, and shows great application potential in fields such as superconducting materials, solar cells, biomedicine, and catalysts.

[0003] During the production of fullerene, a vacuum pumping device is often used for the production of fullerene.

A vacuum generating member, an inert gas generating member, and a soot extraction member are arranged on the vacuum box. The isolating driving member is used to drive the graphite cathode column to rotate to the next movable disk at a predetermined time after the inert gas generating member 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 are matched with the graphite cathode column in succession; The coordination of each graphite anode column and graphite cathode column is as follows: the graphite cathode column and the graphite anode column are in contact and energized at the same time; after a predetermined time has passed since the graphite cathode column and the graphite anode column were energized, the driving compensation driving 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; when the distance between the graphite anode column and the graphite cathode column reaches a predetermined value and gradually shrinks as the graphite anode column continues to evaporate, the driving component drives the graphite anode column close to the graphite cathode column.

[0012] Furthermore, the linkage rod and the vacuum box are connected through a heat-resistant sealing layer. The heat-resistant sealing layer is used to prevent the generated heat and the mixture containing fullerenes from entering the adapter box through the connection between the linkage rod and the vacuum box during the cooperation between the graphite anode column and the graphite cathode column.

[0013] Furthermore, the vacuum box includes a box body disposed on the frame, and a box cover is detachably disposed on the top end surface of the box body.

[0014] Furthermore, a cooling limit seat is disposed inside the vacuum box and below the graphite cathode column. The cooling limit seat is located between several movable disks. A cooling channel is disposed inside the cooling limit seat. The cooling limit seat and the vacuum box are connected through a first hollow connecting rod and a second hollow connecting rod.

[0016] Accordingly, the present invention provides the following effects and / or advantages: 1) The vacuum generating member is used to evacuate the vacuum chamber to a predetermined vacuum, and the inert gas generating member is used to input a predetermined amount of inert gas into the vacuum chamber after the vacuum generating member evacuates the vacuum chamber to the predetermined vacuum.

[0017] The partition rotation driving member is used to drive the graphite cathode column to rotate to the next movable disk every predetermined time after the inert gas generating member inputs a predetermined amount of inert gas into the vacuum chamber until it rotates to each movable disk, so that several graphite anode columns on each movable disk are successively matched with the graphite cathode column, thereby generating a sufficient amount of fullerene-containing mixture in a limited space.

[0018] The pre-rotation land matching driving member is used to drive several graphite anode columns on the movable disk to be successively matched with the graphite cathode column after the inert gas generating member inputs a predetermined amount of inert gas into the vacuum chamber and before the graphite cathode column rotates to the next movable disk.

[0019] The matching of each graphite anode column and the graphite cathode column is as follows: The graphite cathode column is in contact with the graphite anode column and is energized simultaneously to generate an arc to evaporate the graphite anode column, generating a fullerene-containing mixture; after the graphite cathode column and the graphite anode column are energized for a predetermined time, the remote compensation driving member drives the graphite anode column away from the graphite cathode column until the distance between the graphite anode column and the graphite cathode column is a predetermined value to prevent short circuit, thereby ensuring that the graphite anode column continuously evaporates and continuously generates a fullerene-containing mixture; when the distance between the graphite anode column and the graphite cathode column is a predetermined value and during the period when the distance between the graphite anode column and the graphite cathode column shortens as the graphite anode column continuously evaporates, the gradually shrinking driving member drives the graphite anode column closer to the graphite cathode column to maintain the distance between the graphite anode column and the graphite cathode column at a predetermined value, so as not to cause the distance between the graphite anode column and the graphite cathode column to exceed the predetermined value and prevent the graphite anode column from stably and effectively evaporating.

[0020] The remote compensation driving member is used to drive the graphite anode column closer to the graphite cathode column when the gradually shrinking driving member fails to effectively maintain the distance between the graphite anode column and the graphite cathode column for distance compensation, thereby ensuring that the distance between the graphite anode column and the graphite cathode column is a predetermined value and ensuring that the graphite anode column can stably and effectively evaporate.

[0021] The bearing and limiting guide sleeve is used to support and limit the graphite anode column when it is not engaged with the graphite cathode column, so that the graphite anode column is stable within the bearing and limiting guide sleeve, thereby preventing the graphite anode column from failing to align and fit with the graphite cathode column; the bearing and limiting guide sleeve is used to guide the movement of the graphite anode column during the period when the graphite anode column is engaged with the graphite cathode column and the gradual contraction driving member drives the graphite anode column close to the graphite cathode column, so as to prevent the graphite anode column from shifting during movement, thereby preventing the graphite anode column from failing to align and cooperate with the graphite cathode column.

[0022] The soot extraction member is used to drive and extract the mixture containing fullerenes in the vacuum chamber out of the vacuum chamber after several graphite anode columns on each movable disk are successively engaged with the graphite cathode column.

[0023] In summary: it can make the graphite cathode column rotate to the next predetermined position every predetermined time until it rotates to each predetermined position; it can make several graphite anode columns at each predetermined position successively cooperate with the graphite cathode column to generate a sufficient amount of mixture containing fullerenes in a limited space; when the graphite anode column cooperates with the graphite cathode column, it can prevent short circuit, so as to ensure that the graphite anode column continuously evaporates and continuously generates a mixture containing fullerenes; when the graphite anode column cooperates with the graphite cathode column, it can make the graphite anode column stably and effectively evaporate.

[0024] 2) The supporting and blocking push plate is used to block the mixture containing fullerenes generated during the period when the gradual contraction driving member drives the graphite anode column close to the graphite cathode column, so as to prevent the mixture containing fullerenes generated from adhering to the compression spring, thereby prolonging the service life of the compression spring and ensuring the use effect of the compression spring; the supporting and blocking push plate is used to push the mixture containing fullerenes adhering to the inner wall of the bearing and limiting guide sleeve out of the bearing and limiting guide sleeve during the period when the gradual contraction 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 and limiting guide sleeve, thereby preventing the mixture containing fullerenes from adhering to the new graphite anode column.

[0025] 3) The heat-resistant sealing layer is used to prevent the generated heat and the mixture containing fullerenes from entering the connection box through the connection between the linkage rod and the vacuum chamber during the period when the graphite anode column cooperates with the graphite cathode column, prevent the second rotation motor from being damaged and causing other graphite anode columns on the movable disk to fail to successively cooperate with the graphite cathode column, and prevent the telescopic motor from being damaged and causing the driving member to be unable to drive the graphite anode column away from the graphite cathode column after the graphite cathode column and the graphite anode column are energized for a predetermined time.

[0026] 4) The lid is used to be driven to separate from the box body after the soot extraction part extracts the mixture containing fullerenes in the vacuum box, so that a new graphite anode column can be loaded into the bearing guide sleeve; the lid 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 bearing guide sleeve, so that the graphite cathode column is aligned and fitted with the uppermost graphite anode column of one of the movable disks.

[0027] 5) During the successive cooperation of several graphite anode columns on the movable disk with the graphite cathode column, 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 extraction pump, the inlet pipe, and the return pipe can reduce the temperature in the vacuum box, facilitating the generation of the mixture containing fullerenes; The cooling limit seat is used to prevent the generated mixture containing fullerenes from forming near other movable disks during the successive cooperation of several graphite anode columns on the movable disk with the graphite cathode column. 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 covering too much of the mixture containing fullerenes, which may cause the graphite anode columns to be unable to generate electric arcs and evaporate.

The objectives and other advantages of the present invention are achieved and obtained by the structures specifically pointed out in the description and the drawings.
