Description

Technical Field

[0001] This utility model relates to the field of experimental device technology, specifically to a high-efficiency electric arc reaction device for fullerene production. Background Technology

[0002] The electric arc method involves evacuating the arc chamber to a high vacuum and then introducing an inert gas such as helium. The arc chamber contains a cathode and an anode for the preparation of fullerenes. The cathode material is usually a spectroscopic-grade graphite rod, and the anode material is also usually a graphite rod. Typically, tungsten, nickel, copper, or tungsten carbide are added to the anode electrode as a catalyst. When two high-purity graphite electrodes approach each other and perform an electric arc discharge, the carbon rods vaporize to form plasma. Under the inert atmosphere, small carbon molecules collide, merge, and close repeatedly to form stable C60 and high-carbon fullerene molecules. These molecules exist in a large amount of particulate soot and are deposited on the inner wall of the reactor. The soot is collected for extraction.

[0003] Chinese Patent CN209522578U discloses an arc discharge device for preparing fullerenes, including a reactor. A flange is provided on one side of the reactor exterior, and a cathode rod is fixed to the upper end of the flange. The cathode rod is vertically inserted into the reactor, and a cathode plate is installed at one end inside the reactor. Several cathode discharge electrodes are arranged side by side at the lower end of the cathode plate. One end of a movable rod is connected to an anode rod, and the other end is connected to the output end of an electric telescopic rod. A distance sensor is embedded inside each cathode discharge electrode. A gas collection chamber is provided at the top of the reactor. A filter baffle is embedded in the inner wall of the top of the buffer chamber. Several gas equalization holes are provided in the filter baffle. The side end of the buffer chamber is connected to a vacuum pump, and a valve is provided on the gas guide pipe. A sealing cover is fitted on the outer wall of the reactor. A water storage chamber is provided at the top of the cooling cavity, and a drainage chamber is provided at the bottom of the cooling cavity. The bottom of the drainage chamber is connected to a water tank. One side of the bottom of the water tank is connected to the water storage chamber through a water guide pipe, and water is installed on the water guide pipe.

[0004] However, in the above technical solution, the distance between the anode rod and the cathode discharge electrode can be automatically adjusted under the control of the main control panel by setting a distance sensor and an electric telescopic rod, so as to ensure the efficient reaction. However, the electric arc will continue to act on the same area of ​​the anode, causing that area to be consumed rapidly, while other areas are consumed more slowly, eventually forming a conical or uneven surface. The unevenness of the graphite rod surface will reduce the yield and purity of fullerene by destroying the stability of the electric arc, interfering with the uniformity of carbon vapor and increasing the generation of by-products. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a high-efficiency electric arc reaction device for fullerene production.

[0006] The technical solution of this utility model is as follows: A high-efficiency electric arc reactor for fullerene production includes a reactor body with multiple pipes connected to its side wall, and a first flange connected to each pipe; a second flange connected to the first flange, with a support plate connected to one end of the second flange; a cathode rod connected to the second flange, with one end of the cathode rod disposed inside the reactor body, and a cathode trigger plate connected to the cathode rod; an anode rod arranged parallel to the cathode rod, positioned below the cathode rod, with one end of the anode rod disposed inside the reactor body; and a moving assembly connected to the second flange. The moving assembly includes a linear sliding module, a connecting rod, and a rotating component. The linear sliding module is connected to the support plate, the connecting rod is collinear with the anode rod, one end of the connecting rod is connected to a slide table of the linear sliding module, and the rotating component is connected to the support plate, with the connecting rod connected to the rotating component. In the operation of the moving assembly, the slide table of the linear sliding module drives the connecting rod to push the anode rod closer to the cathode rod, and the rotating component rotates as it moves along its own axis when it contacts the connecting rod.

[0007] Preferably, the connecting rod consists of a sealing rod body and a moving rod body. One end of the sealing rod body is connected to the moving rod body, and the other end of the sealing rod body is connected to an installation sleeve. The anode rod is connected inside the installation sleeve, and two spiral guide grooves are formed on the outer peripheral wall of the moving rod body.

[0008] Preferably, the rotating component consists of a fixed plate and a locking block. Two symmetrically arranged fixed plates are connected to a support plate, and locking blocks are connected to opposite sides of the fixed plates. The locking blocks are slidably connected to guide grooves opened on the moving rod.

[0009] Preferably, the cathode trigger plate is connected to multiple evenly distributed bumps, the cathode trigger plate is made of graphite, and the bumps are made of metal.

[0010] Preferably, both the cathode rod and the anode rod are graphite rods.

[0011] Preferably, an observation window is provided on the main body of the reactor.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] In this invention, when the anode rod is pushed close to the cathode trigger plate by the linear sliding module, the rotating part will contact the connecting rod. The spiral guide groove on the moving rod that forms the connecting rod will slide with the locking block on the fixed plate. The locking block restricts the moving rod to rotate when it moves horizontally, thereby causing the connecting rod and the anode rod to rotate. This allows the anode rod to rotate continuously during the evaporation process, ensuring that its surface is in uniform contact with the electric arc. This allows the graphite to be evaporated and consumed evenly. Uniform consumption keeps the anode surface flat, preventing the formation of cones or pits. Uniform consumption can also avoid local over-evaporation and improve the effective utilization rate of a single graphite rod. Attached Figure Description

[0019] Example 1

[0020] like Figures 1-4 As shown, this utility model proposes a high-efficiency electric arc reactor for fullerene production, comprising a reactor body 1, pipes 2, a first flange 3, a second flange 4, a support plate 5, a cathode rod 6, a cathode trigger plate 7, an anode rod 8, and a moving assembly. Multiple pipes 2 are connected to the side wall of the reactor body 1, and the first flange 3 is connected to each pipe 2. The second flange 4 is flange-connected to the first flange 3, and a support plate 5 is connected to one end of the second flange 4. The cathode rod 6 is connected to the second flange 4, and one end of the cathode rod 6 is disposed inside the reactor body 1. The cathode trigger plate 7 is connected to the cathode rod 6. The anode rod 8 is arranged parallel to the cathode rod 6 and is positioned within the cathode rod 6. Below the electrode rod 6, one end of the anode rod 8 is set inside the reactor body 1, and the moving component is connected to the second flange 4. The moving component includes a linear sliding module 9, a connecting rod 10, and a rotating component 11. The linear sliding module 9 is connected to the support plate 5. The connecting rod 10 is collinear with the anode rod 8. One end of the connecting rod 10 is connected to the slide table of the linear sliding module 9. The rotating component 11 is connected to the support plate 5, and the connecting rod 10 is connected to the rotating component 11. When the moving component is in use, the slide table of the linear sliding module 9 drives the connecting rod 10 to push the anode rod 8 closer to the cathode rod 6. When the rotating component 11 contacts the connecting rod 10, it rotates along its own axis.

[0021] In an optional embodiment, an observation window 18 is provided on the reactor body 1.

[0022] Example 2

[0023] like Figures 3-4 As shown, the present invention proposes a high-efficiency electric arc reaction device for fullerene production. Compared with Embodiment 1, this embodiment describes the detailed structure of the connecting rod 10. The connecting rod 10 consists of a sealing rod body 12 and a moving rod body 13. One end of the sealing rod body 12 is connected to the moving rod body 13, and the other end of the sealing rod body 12 is connected to an installation sleeve. The anode rod 8 is connected inside the installation sleeve. Two spiral guide grooves 14 are opened on the outer peripheral wall of the moving rod body 13.

[0024] In an optional embodiment, the rotating component 11 consists of a fixed plate 15 and a locking block 16. Two symmetrically arranged fixed plates 15 are connected to the support plate 5. The fixed plates 15 are connected to the locking blocks 16 on opposite sides. The locking blocks 16 are slidably connected to the guide grooves 14 opened on the moving rod 13.

[0025] Example 3

[0026] like Figure 3 As shown, this utility model proposes a high-efficiency electric arc reaction device for fullerene production. Compared with Embodiment 2, this embodiment describes the detailed structure of the electric arc reaction system.

[0027] In an optional embodiment, a plurality of evenly distributed bumps 17 are connected to the cathode trigger plate 7. The cathode trigger plate 7 is made of graphite, and the bumps 17 are made of metal. The bumps 17 are made of, but are not limited to, tungsten and molybdenum. Both of these metal materials have a long lifespan, can reduce the number of maintenance times, and have high breakdown voltage stability.

[0028] In an optional embodiment, both the cathode rod 6 and the anode rod 8 are graphite rods.

[0029] In summary, when using this invention, after installing the graphite rod, the main body 1 of the reactor is evacuated and injected with protective inert gas. After starting the power, the anode rod 8, cathode rod 6, and cathode trigger plate 7 form a loop-shaped flow guide circuit in the furnace body. When the anode rod 8 approaches the protrusion 17 on the cathode trigger plate 7, an arc discharge phenomenon is generated. The arc discharge phenomenon will cause the anode rod 8 to evaporate and consume rapidly in the arc, producing a mixture containing fullerene. At the same time, the linear sliding module 9 is started. The sliding table of the linear sliding module 9 moves, driving the connecting rod 10 composed of the sealing rod 12 and the moving rod 13 to move linearly. When the moving rod 13 moves, the spiral guide groove 14 on its outer side wall contacts the locking block 16. The locking block 16 will cause the moving rod 13 to rotate during the movement, thereby driving the anode rod 8 to rotate. This makes the graphite rod of the anode rotate during the preparation of fullerene, so that the arc is evenly distributed to enhance production efficiency.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
