Description

Technical Field

[0001] This invention generally relates to the field of carbon-based catalyst preparation technology, and more specifically, to a carbon-based catalyst preparation apparatus. Background Technology

[0002] Graphdiyne (GDY) is a carbon-based catalyst and a novel carbon nanostructure material following fullerenes, carbon nanotubes, and graphene. Graphdiyne is composed of unique sp-sp2 carbon atoms and possesses excellent electrical conductivity, a highly π-conjugated atomic structure, and a uniformly distributed sub-nanopore structure, giving it great potential for development as a catalyst and catalyst support. Furthermore, Graphdiyne is widely used in energy, biomedicine, and separation analysis.

[0003] Current methods for preparing graphyne involve first dispersing graphyne precursor molecules and a coupling catalyst in an organic solvent, then reacting them in a microwave reactor according to a specific program to obtain a graphyne dispersion. However, this method has the following drawbacks: 1. It can only be prepared in a single mode, and cannot match the preparation mode to different raw materials, making it difficult to meet the diverse preparation needs of users; 2. It requires multiple repetitive manual operations, involves complex formulation control, has relatively low preparation precision, and results in small single-batch synthesis, affecting production efficiency.

The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0144] This embodiment provides a carbon-based catalyst preparation apparatus, such as... Figure 1 As shown, the carbon-based catalyst preparation apparatus includes a base 1, a carrier 2 mounted on the base 1, a solid-phase conveying mechanism 3, a liquid-phase conveying mechanism 4, a weighing mechanism 5, a transfer mechanism 11, and a reaction mechanism 7. The carrier 2, solid-phase conveying mechanism 3, liquid-phase conveying mechanism 4, and reaction mechanism 7 are arranged around the transfer mechanism 11. The carrier 2 is used to carry the apparatus 20. The solid-phase conveying mechanism 3 is used to convey solid raw materials, the liquid-phase conveying mechanism 4 is used to convey liquid raw materials, and the weighing mechanism 5 is used to weigh the apparatus 20.

[0145] The base 1 is similar to a cuboid structure. The base 1 has at least one plane that is parallel to the horizontal plane. The first direction and the second direction are two directions that are perpendicular to each other on the plane. The third direction is perpendicular to the plane. The first direction, the second direction and the third direction are perpendicular to each other. The first direction is identified by D1, the second direction by D2, and the third direction by D3.

[0146] The carrier 2 can be an apparatus rack, which provides a placement location for the apparatus 20 and provides a certain degree of support for the apparatus 20. The apparatus 20 is a container for holding solid or liquid raw materials, and different apparatus 20 can be selected according to the state of the raw materials. For example, the apparatus 20 can be a Y-shaped rack, a beaker, a crucible, etc.

[0147] The weighing mechanism 5 can be a balance, weighing device, or other device with weighing function. When there is no solid or liquid raw material in the apparatus 20, the weighing mechanism 5 is used to weigh the apparatus 20 first; when solid or liquid raw material is placed in the apparatus 20, the weighing mechanism 5 is used to weigh the apparatus 20 again. By comparing the values ​​of the two weighing mechanisms 5, the weight of the solid or liquid raw material in the apparatus 20 can be determined, thereby allowing for precise control of the amount of raw material used and improving the accuracy of preparation.

[0148] The solid-phase conveying mechanism 3 is used to convey solid raw materials. These solid raw materials can be graphyne precursors, reaction catalysts, graphyne monomers, and coupling catalysts, etc.

[0149] The liquid transport mechanism 4 is used to transport liquid raw materials. These liquid raw materials can be organic reagents, etc.

[0150] The reaction mechanism 7 can be a microwave reaction mechanism or other heating reaction mechanism, and different types of reaction mechanisms 7 can be selected according to the different states of the raw materials. Of course, the preparation can be carried out by mixing only solid raw materials, mixing only liquid raw materials, or mixing solid and liquid raw materials.

[0151] Among them, the transfer mechanism 11 can be a robotic arm, which can grasp the instrument 20 and transport the instrument 20 to the solid phase conveying mechanism 3, the liquid phase conveying mechanism 4, the weighing mechanism 5 and the reaction mechanism 7 respectively to realize different process stages.

[0152] In one embodiment, the transfer mechanism 11 is configured to transport the apparatus 20 to the weighing mechanism 5. After the solid phase transport mechanism 3 adds solid raw materials to the apparatus 20, the liquid phase transport mechanism 4 and the solid phase transport mechanism 3 selectively add liquid raw materials or different solid raw materials into the apparatus 20 to switch between solid mixing mode and solid-liquid mixing mode, and transport them to the reaction mechanism 7 through the transfer mechanism 11 to generate graphylene product in the reaction mechanism 7.

[0153] For example, in solid mixing mode, the transfer mechanism 11 is configured to transport the apparatus 20 to the weighing mechanism 5, and use the solid phase transport mechanism 3 to add different solid raw materials into the apparatus 20 located in the weighing mechanism 5, so that the different solid raw materials are mixed in the apparatus 20, and then transported to the reaction mechanism 7 through the transfer mechanism 11 to generate graphylene product in the first reaction mechanism 7.

[0154] For example, in the solid-liquid mixing mode, the transfer mechanism 11 is configured to transport the apparatus 20 to the weighing mechanism 5, use the solid phase transport mechanism 3 to add solid raw materials into the apparatus 20 located in the weighing mechanism 5, use the liquid phase transport mechanism 4 to add liquid raw materials into the apparatus 20, so that the solid raw materials and liquid raw materials are mixed in the apparatus 20, and then transported to the reaction mechanism 7 through the transfer mechanism 11 to generate the graphylene product in the reaction mechanism 7.

[0155] The carbon-based catalyst preparation apparatus provided in this embodiment has a reaction mechanism 7, a carrier 2, a solid phase transport mechanism 3, and a liquid phase transport mechanism 4 arranged in a ring around a transfer mechanism 11, so that the transfer mechanism 11 is located in a near-central position. This facilitates the transfer mechanism 11 to transport the apparatus 20 to each mechanism, saving the transfer time of the apparatus 20, realizing high-throughput preparation of graphyne materials, with a high degree of automation, and improving the production efficiency of graphyne material preparation.

[0156] With the coordinated action of the solid phase conveying mechanism 3, the liquid phase conveying mechanism 4, the weighing mechanism 5, and the reaction mechanism 7, different solid raw materials are mixed in the solid mixing mode to complete the graphylene product preparation process; in the solid-liquid mixing mode, solid raw materials and liquid raw materials are mixed to complete the graphylene product preparation. The corresponding mixing mode can be switched according to different raw material types, which is flexible, functional, and meets the diverse needs of users.

[0157] Using the same solid-phase conveying mechanism 3, solid raw materials can be provided not only in solid mixing mode but also in solid-liquid mixing mode. The preparation function can be realized without adding other components, saving the number of conveying mechanisms and reducing production costs.

[0158] In the embodiments of this application, the solid raw material conveying process, the liquid raw material conveying process, and the reaction process are independent. That is, when one device 20 is reacting in the reaction mechanism 7, other mechanisms can simultaneously convey raw materials to another device 20; when the reaction in the reaction mechanism 7 stops, the other device 20 can continue to enter the reaction mechanism 7, thereby improving the utilization rate of different mechanisms and increasing the yield of graphyne samples.

[0159] Meanwhile, the carbon-based catalyst preparation device provided in this embodiment has the advantages of high operability, high precision, and good versatility. It can be matched with the preparation of other types of materials and is applicable to various fields such as catalysis, biology, and medicine, with strong versatility.

[0160] The following sections describe the carrier 2, solid phase transport mechanism 3, weighing mechanism 5, transfer mechanism 11, reaction mechanism 7, and liquid phase transport mechanism 4.

[0161] like Figure 2As shown, the carrier 2 includes a frame 21 and shelves 22. Shelves 22 are disposed on the frame 21. There can be multiple shelves 22. Multiple shelves 22 are spaced apart in the frame 21 along a third direction to provide placement positions for different appliances 20 and to avoid confusion when there are a large number of appliances 20.

[0162] The apparatus 20 includes a first apparatus 23, which is disposed on the shelf 22 of the carrier 2. For example, the first apparatus 23 may be a beaker. The first apparatus 23 is disposed on the bottom shelf 22 and is used to contain a mixture of solid and liquid raw materials in a solid-liquid mixing mode. Multiple receiving slots 272 may be provided on the shelf 22 to contain multiple first apparatuses 23, providing receiving positions for different first apparatuses 23 and, to a certain extent, limiting the position of the first apparatuses 23.

[0163] The device 20 also includes a second device 24, which is disposed on the carrier 2. For example, the second device 24 may be a Y-shaped frame. The second device 24 is disposed on the top shelf 22 of the carrier 2. The second device 24 is used to contain a mixture of solid raw materials in a solid mixing mode.

[0164] Specifically, the second appliance 24 includes a main body 241 and a cover 242. The main body 241 is provided with an open end, and the cover 242 is detachably connected to the main body 241.

[0165] When the second device 24 is not in use, the cap 242 is placed over the opening of the main body 241 to prevent external air and dust contamination when the opening of the main body 241 is open. When the second device 24 needs to be used, the cap 242 is opened to expose the opening, allowing solid raw materials to be added into the second device 24 through the opening.

[0166] The main body 241 includes multiple connecting pipes arranged at an angle, with one end of each pipe connected to the other and the other end having multiple open ends. For example, the connecting pipes can be three, intersecting to form a Y-shaped structure, and the second device 24 can also be called a Y-shaped frame.

[0167] This configuration, with multiple interconnecting pipes arranged at an angle, provides a space for the solid raw materials to distribute at a certain angle, increasing the distribution range of the solid raw materials within the second apparatus 24. For example, when solid raw materials such as graphylene precursors and catalyst powders are placed into the second apparatus 24, during subsequent mechanical stirring or other subsequent mixing processes, the solid raw materials at different locations will flow and disperse between the multiple interconnecting pipes of the second apparatus 24, causing the solid raw materials to come into contact and collide with each other, thereby improving the uniformity and thoroughness of mixing.

[0168] The carrier 2 also includes a base 25. A V-shaped groove 251 is provided on the side of the base 25 facing the second device 24. The second device 24 is disposed in the V-shaped groove 251. The included angle between the two groove walls of the V-shaped groove 251 is adapted to the included angle between the two connecting pipes of the second device 24, so that the two caps 242 of the second device 24 can be placed on the two groove walls of the V-shaped groove 251 to provide stable support for the second device 24.

[0169] The carrier 2 also includes a limiting block 252, which is disposed on the base 25 and is used to limit the second device 24 to prevent the second device 24 from moving relative to the base 25. The number of limiting blocks 252 can be multiple, and the second device 24 can be located between two adjacent limiting blocks 252 to separate multiple second devices 24.

[0170] In one embodiment, the apparatus 20 further includes a reactor vessel 26, which is disposed on the carrier 2. For example, the reactor vessel 26 may be a crucible, disposed on the topmost shelf 22 of the carrier 2, and is used to contain a mixture of solid raw materials in a solid mixing mode.

[0171] If the second apparatus 24 has high-temperature resistance, after mixing the solid raw materials in the second apparatus 24, the second apparatus 24 can be placed directly into the reaction mechanism 7. If the second apparatus 24 does not have high-temperature resistance, but the reactor apparatus 26 has high-temperature resistance, after mixing the solid raw materials in the second apparatus 24, the mixed solid raw materials can be poured into the reactor apparatus 26, and then the reactor apparatus 26 can be placed into the reaction mechanism 7. The reactor apparatus 26 serves as a transfer device to prevent the second apparatus 24 from being damaged if it is placed directly into the reaction mechanism 7.

[0172] In one embodiment, such as Figure 2 As shown, the carrier 2 includes a support assembly 27, which includes a bracket 271, a column 274, and a dust cover 273. The bracket 271 is provided with a receiving groove 272, and the reactor 26 is disposed in the receiving groove 272. The column 274 is disposed on the bracket 271, and the dust cover 273 is sleeved on the column 274 and correspondingly disposed in the receiving groove 272. The dust cover 273 serves to prevent dust.

[0173] In one embodiment, such as Figures 3-5 As shown, the solid phase conveying mechanism 3 includes a bearing component 31, a powder injection mechanism 32, and multiple powder storage tanks 33. The multiple powder storage tanks 33 are disposed on the bearing component 31 and are used to contain solid raw materials.

[0174] The supporting component 31 provides a support location for multiple powder storage tanks 33. Different powder storage tanks 33 can store the same solid raw materials or different solid raw materials. For example, different solid raw materials such as graphylene precursors and reaction catalysts can be stored independently in different powder storage tanks 33 to avoid mixing and contamination of solid raw materials.

[0175] The weighing mechanism 5 is located between the bearing component 31 and the powder injection mechanism 32, that is, the bearing component 31 and the weighing mechanism 5 are arranged adjacent to each other. The distance between the bearing component 31 and the weighing mechanism 5 is relatively small, which reduces the path of the powder storage tank 33 from the bearing component 31 to the weighing mechanism 5, reduces the loss of solid raw materials due to spillage during long-distance transfer, and thus improves the weighing accuracy.

[0176] Among them, the powder injection mechanism 32 can drive the powder storage tank 33 to the weighing mechanism 5 and inject the solid raw materials in the powder storage tank 33 into the appliance 20.

[0177] A powder injection mechanism 32 can drive the powder storage tank 33 to complete both the transfer and injection processes, eliminating the need for manual handling or injection and improving production efficiency. Simultaneously, after completing the weighing process with the powder storage tank 33, the powder injection mechanism 32 can directly add the solid raw materials from the tank to the apparatus 20, eliminating the time gap between the weighing and injection processes, reducing transitions, saving production time, and minimizing material loss during transfer, thereby improving preparation accuracy.

[0178] In one embodiment, such as Figures 4-6 As shown, the bearing assembly 31 includes a bearing frame 311 and multiple support seats 312. The multiple support seats 312 are disposed on the bearing frame 311, and a support cavity 3121 is provided in the support seat 312. The multiple powder storage tanks 33 are at least partially disposed in the support cavity 3121 of the multiple support seats 312.

[0179] The inner shape of the support cavity 3121 is adapted to the outer wall shape of the powder storage tank 33. For example, the lower end of the powder storage tank 33 is similar to a conical structure, and the inner cavity of the support cavity 3121 is also a conical structure, so that the support seat 312 can provide good support for the powder storage tank 33.

[0180] Among them, such as Figure 5 and Figure 7As shown, one of the support base 312 and the powder storage tank 33 is provided with a positioning groove 3122, and the other is provided with a positioning protrusion 3311. The positioning protrusion 3311 is disposed within the positioning groove 3122. For example, the support base 312 is provided with a positioning groove 3122, and the outer wall of the powder storage tank 33 is provided with a positioning protrusion 3311. The positioning protrusion 3311 cooperates with the positioning groove 3122 to ensure the positioning between the powder storage tank 33 and the support base 312, and to ensure the accuracy of the position of the powder storage tank 33 relative to the support base 312.

[0181] In one embodiment, such as Figures 6-7 As shown, the bearing assembly 31 also includes a plurality of sealing covers 313, which are respectively covered on the outside of the plurality of support seats 312. A sealing cavity is formed between the sealing covers 313 and the support seats 312, and the powder storage tank 33 is disposed in the sealing cavity.

[0182] In this manner, the sealed cavity between the sealing cover 313 and the support base 312 provides a closed storage environment for the powder storage tank 33, effectively isolating it from moisture, dust, and other impurities in the external air. This prevents external dust from contaminating the powder storage tank 33, serving as a moisture-proof and dust-proof measure and preventing leakage, contamination, and deliquescence of solid raw materials. Furthermore, if the raw material is volatile, the sealed cavity reduces the escape of solid raw materials due to trace amounts of volatilization, preventing cross-contamination between different powder storage tanks 33 and ensuring the independence and safety of each powder storage tank 33.

[0183] In one embodiment, the powder storage tank 33 is made of a corrosion-resistant material, such as polytetrafluoroethylene, suitable for strong acid or alkaline environments. A single powder storage tank 33 can hold 40g to 80g.

[0184] like Figures 5-6 As shown, the powder storage tank 33 includes a tank body 331 and a powder injection head 332. The tank body 331 is used to contain solid raw materials. One end of the powder injection head 332 is detachably connected to the tank body 331, and the other end is provided with a discharge port 3321.

[0185] The tank body 331 has a cylindrical shape and can be detached from the powder injection head 332 using bolts, threads, or other methods, facilitating their installation and removal. During use, the powder injection head 332 is removed from the tank body 331 to allow for the addition of solid raw materials, which is beneficial for the solid materials.

[0186] The powder injection head 332 has a cone-shaped structure, with a large end and a small end. The large end of the powder injection head 332 is connected to the tank body 331, and can accommodate a large area of ​​solid raw materials inside the tank body 331. The discharge port 3321 is located at the small end of the powder injection head 332 to prevent the solid raw materials from being discharged too quickly. At the same time, the inner wall surface of the powder injection head 332 is inclined, which provides a certain guiding force for the solid raw materials, facilitating the discharge of solid raw materials from the discharge port 3321.

[0187] In one embodiment, such as Figure 5 and Figure 8 As shown, the powder storage tank 33 also includes a stirring component 333, which is at least partially disposed within the tank body 331. The powder injection mechanism 32 is configured to clamp the tank body 331 and move it to the weighing mechanism 5. The powder injection mechanism 32 can also drive the stirring component 333 to rotate relative to the tank body 331, causing the solid raw material within the tank body 331 to fall from the discharge port 3321 into the container 20 located in the weighing mechanism 5.

[0188] Driven by the powder injection mechanism 32, the stirring component 333 can rotate relative to the tank 331 inside the tank 331 to stir the solid raw materials inside the tank 331. The directional thrust generated by the stirring component 333 can push the solid raw materials to the discharge port 3321, avoiding the accumulation of solid raw materials in the tank 331 and causing blockage of the discharge port 3321, thereby ensuring the smooth discharge of solid raw materials.

[0189] In one embodiment, the stirring component 333 includes a connecting rod 3331, which passes through the tank body 331, and the outer wall of the connecting rod 3331 is provided with a guide portion 3332 along a spiral line.

[0190] The connecting rod 3331 extends along the axial direction of the tank 331 to increase the agitation range within the tank 331.

[0191] The guide part 3332 may be a spiral blade, which is wound around the outer wall of the connecting rod 3331 along a spiral trajectory. When the powder injection mechanism 32 can drive the connecting rod 3331 to rotate relative to the tank 331, the guide part 3332 plays a guiding role to guide the solid raw material in the tank 331 toward the discharge port 3321, which is beneficial to the discharge process of the solid raw material.

[0192] In one embodiment, the stirring component 333 further includes a baffle 3333, which is disposed at the end of the connecting rod 3331 facing the discharge port 3321. The cross-sectional area of ​​the baffle 3333 is smaller than the area of ​​the discharge port 3321. For example, the discharge port 3321 may be a circular through hole, and the shape of the baffle 3333 is similar to a D-shaped structure.

[0193] Among them, the powder injection mechanism 32 can drive the connecting rod 3331 to rotate relative to the tank body 331, so that the baffle 3333 at least partially covers the discharge port 3321.

[0194] As the connecting rod 3331 rotates, the overlapping area between the baffle 3333 and the discharge port 3321 changes with the rotation angle of the connecting rod 3331. That is, the straight edge and the arc edge of the baffle 3333 alternately approach the discharge port 3321 to change the discharge channel formed between the baffle 3333 and the discharge port 3321. When rapid discharge is required, the baffle 3333 is controlled to cover only a small area of ​​the discharge port 3321 to increase the area of ​​the discharge channel. When the weighing of solid raw materials is close to the target value, the baffle 3333 is controlled to increase the area covering the discharge port 3321, reduce the area of ​​the discharge channel, and make the solid raw materials fall slowly, realizing the process of micro-feeding.

[0195] By adding a baffle 3333 with a cross-sectional area smaller than the discharge port 3321 and a D-shaped structure to the end of the connecting rod 3331 facing the discharge port 3321, and by driving the connecting rod 3331 to rotate via the powder injection mechanism 32, the baffle 3333 partially covers the discharge port 3321. By controlling the rotation speed of the connecting rod 3331 driven by the powder injection mechanism 32, the discharge speed of the solid raw material can be controlled, thereby regulating the discharge flow rate.

[0196] This spiral stirring method enables precise addition of solid raw materials, with a single addition amount of approximately 20g to 100g.

[0197] In one embodiment, such as Figure 9 As shown, the powder injection mechanism 32 includes a clamping assembly 321, a powder injection rotation assembly 322, and a powder injection moving assembly 323. The clamping assembly 321 is used to clamp the tank 331. The powder injection rotation assembly 322 is connected to the stirring component 333 and can drive the stirring component 333 to rotate. The powder injection moving assembly 323 is disposed on the powder injection worktable 34 and is connected to the clamping assembly 321 and the powder injection rotation assembly 322. The powder injection moving assembly 323 can drive the clamping assembly 321 and the powder injection rotation assembly 322 to move along a first direction, a second direction, and a third direction; wherein the first direction, the second direction, and the third direction are perpendicular to each other.

[0198] When powder needs to be injected into the apparatus 20 on the weighing mechanism 5, the powder injection moving component 323 can drive the clamping component 321 and the powder injection rotating component 322 to move towards the powder storage tank 33. The clamping component 321 clamps the tank body 331 of the powder storage tank 33, so that the powder storage tank 33 can move with the movement of the powder injection moving component 323. When the powder storage tank 33 is above the apparatus 20, the powder injection rotating component 322 can drive the stirring component 333 to rotate, so that the solid raw material in the powder storage tank 33 falls from the discharge port 3321 into the apparatus 20, realizing the powder injection process.

[0199] The powder injection mechanism 32 provided in this embodiment uses a clamping component 321 to clamp the powder storage tank 33, preventing the powder storage tank 33 from becoming loose, tilted, or falling off during movement or stirring, ensuring that the powder storage tank 33 remains stable and preventing the solid raw materials inside the powder storage tank 33 from being lost due to spillage. The powder injection rotation component 322 and the stirring component 333 are connected by a drive mechanism. The powder injection rotation component 322 provides rotational power to the stirring component, making the feeding speed of the solid raw materials uniform. By adjusting the rotation speed of the powder injection rotation component 322, the powder injection speed can be adjusted to meet different powder injection requirements, such as uniform feeding or micro-feeding.

[0200] In one embodiment, such as Figure 10 As shown, the clamping assembly 321 includes a clamping drive source 3211 and two jaws 3212. The clamping drive source 3211 may be a clamping cylinder. The clamping drive source 3211 can drive the two jaws 3212 to move closer to or further away from each other.

[0201] When the clamping drive source 3211 drives the two jaws 3212 to move closer to each other, the two jaws 3212 can clamp the powder storage tank 33 for fixing the powder storage tank 33; when the clamping drive source 3211 drives the two jaws 3212 to move away from each other, the two jaws 3212 can release the powder storage tank 33 and lock and fix it in contact with the powder storage tank 33.

[0202] Among them, the claw 3212 is provided with a locking engagement part 3213 (such as... Figure 10 As shown), the powder storage tank 33 also includes a snap-fit ​​part 3312 (as shown). Figure 5 As shown), the snap-fit ​​part 3312 is provided on the tank body 331, and the snap-fit ​​part 3312 snaps into the snap-fit ​​mating part 3213.

[0203] For example, a snap-fit ​​part 3312 is provided on the tank body 331 of the powder storage tank 33. The snap-fit ​​part 3312 may be a boss, and the snap-fit ​​part 3213 may be a snap-fit ​​mating part 3213. Of course, the structure and position of the snap-fit ​​part 3312 and the snap-fit ​​mating part 3213 can also be interchanged.

[0204] The snap-fitting between the snap-fitting part 3312 and the snap-fitting mating part 3213 ensures the fixation between the claw 3212 and the powder storage tank 33, further improving the clamping effect of the clamping assembly 321 and preventing the powder storage tank 33 from falling off during movement.

[0205] In one embodiment, such as Figure 10 As shown, the powder injection rotation assembly 322 includes a powder injection rotation drive source 3221 and a powder injection drive gear 3222. The powder injection rotation drive source 3221 can be a rotary motor, and its output end is connected to the powder injection drive gear 3222. The stirring component also includes a powder injection driven gear 3334 (e.g., ...). Figure 5 As shown, the powder injection driven gear 3334 is disposed outside the tank body 331 and sleeved outside the connecting rod 3331. The powder injection driven gear 3334 can mesh with the powder injection driving gear 3222. The powder injection rotation drive source 3221 can drive the powder injection driving gear 3222 to rotate, and drive the connecting rod 3331 to rotate through the powder injection driven gear 3334.

[0206] The powder injection drive gear 3222 and the powder injection driven gear 3334 form a gear meshing transmission. This gear meshing transmission has the advantages of a fixed transmission ratio and low power loss. The power from the powder injection rotary drive source 3221 is directly transmitted to the powder injection driven gear 3334 via the powder injection drive gear 3222, which in turn drives the connecting rod 3331 of the stirring component 333 to rotate, providing the necessary power for the rotation of the stirring component 333. The entire transmission process is smooth and lag-free, ensuring precise matching between the rotational speed of the stirring component 333 and the output speed of the powder injection rotary drive source 3221. By controlling the rotational speed of the powder injection rotary drive source 3221, a constant-speed rotation of the stirring component 333 can be achieved, ensuring the uniformity of the solid raw material feeding rate.

[0207] The powder injection driven gear 3334 is located outside the powder storage tank 33, specifically on the outside of the tank body 331. After the clamping assembly 321 clamps the powder storage tank 33, a transmission connection between the powder injection drive gear 3222 and the powder injection driven gear 3334 can be quickly established without additional docking steps, thus improving the docking efficiency between the powder injection mechanism 32 and the powder storage tank 33. Furthermore, by using an externally mounted powder injection driven gear 3334, it does not affect the internal structure of the powder storage tank 33 and does not contaminate the solid raw materials inside the tank body 331. Simultaneously, when the powder injection driven gear 3334 needs replacement after prolonged use, it can be replaced without disassembling the stirring component 333 inside the powder storage tank 33, facilitating daily inspection and maintenance and reducing maintenance costs.

[0208] In one embodiment, such as Figure 11As shown, the powder injection moving assembly 323 includes a first powder injection moving component 3231, a second powder injection moving component 3232, and a third powder injection moving component 3233. A clamping assembly 321 and a powder injection rotating assembly 322 are connected to the third powder injection moving component 3233. The third powder injection moving component 3233 can drive the clamping assembly 321 and the powder injection rotating assembly 322 to move vertically in a third direction. The second powder injection moving component 3232 is connected to the third powder injection moving component 3233, and can be driven to move in a second direction. The first powder injection moving component 3231 is connected to the second powder injection moving component 3232, and can drive the second powder injection moving component 3232 to move in a first direction.

[0209] With the combined action of the first powder injection moving component 3231, the second powder injection moving component 3232 and the third powder injection moving component 3233, the powder injection moving assembly 323 has three degrees of freedom, enabling the clamping assembly 321 and the powder injection rotating assembly 322 to move along the first direction, the second direction and the third direction respectively.

[0210] In one embodiment, the first powder-filling moving component 3231 includes a first drive source 3231, a second mixing mechanism, a first driving gear 3231b, a first driven gear 3231c, a first conveyor belt 3231d, and a moving frame 3231e. The first drive source 3231, second mixing mechanism, may be a drive motor. The output end of the first drive source 3231, second mixing mechanism, is connected to the first driving gear 3231b. The first driving gear 3231b and the first driven gear 3231c are arranged along a first direction. The first conveyor belt 3231d is wound around the first driving gear 3231b and the first driven gear 3231c. The moving frame 3231e is connected to the first conveyor belt 3231d via a first fixing member. During operation, the first drive source 3231, second mixing mechanism, drives the first driving gear 3231b to rotate, causing the first driven gear 3231c to rotate and the first conveyor belt 3231d to move. As the first conveyor belt 3231d moves, it causes the moving frame 3231e to move along the first direction.

[0211] Among them, the movable frame 3231e is a gate-shaped structure, and the movable frame 3231e provides an installation position for the second powder injection moving component 3232.

[0212] Among them, such as Figure 11As shown, the powder injection worktable 34 is provided with a guide through hole 341. The guide through hole 341 extends along the first direction. The moving frame 3231e passes through the guide through hole 341 and slides in cooperation with the guide through hole 341. The guide through hole 341 provides a clearance position for the movement of the moving frame 3231e, and can also plan a guide path for the moving frame 3231e to ensure the smoothness and accuracy of the movement of the moving frame 3231e.

[0213] Please continue to refer to Figure 11 The second powder injection moving component 3232 includes a second drive source 3232, a second mixing mechanism, a second driving gear 3232b, a second driven gear 3232c, a second conveyor belt 3232d, and a moving base 3232e. The second drive source 3232, the second mixing mechanism, is disposed on the moving frame 3231e. The second drive source 3232, the second mixing mechanism, can be a drive motor. The output end of the second drive source 3232, the second mixing mechanism, is connected to the second driving gear 3232b. The second driving gear 3232b and the second driven gear 3232c are arranged along a second direction. The second conveyor belt 3232d is wound around the second driving gear 3232b and the second driven gear 3232c. The moving base 3232e is connected to the second conveyor belt 3232d through a second fixing member. During operation, the second drive source 3232 and the second hybrid mechanism drive the second drive gear 3232b to rotate, which in turn drives the second driven gear 3232c to rotate and the second conveyor belt 3232d to move. As the second conveyor belt 3232d moves, it drives the moving seat 3232e to move along the second direction.

[0214] Please continue to refer to Figure 11 The third powder injection moving component 3233 includes a third drive source 3233, a second mixing mechanism, and a connecting seat 3233b. The third drive source 3233, second mixing mechanism, is disposed on the moving seat 3232e. The third drive source 3233, second mixing mechanism can be a moving motor, a lifting cylinder, a lifting hydraulic cylinder, etc. The output end of the third drive source 3233, second mixing mechanism, is connected to the moving seat 3232e, which is used to mount the clamping assembly 321 and the powder injection rotating assembly 322. The third drive source 3233, second mixing mechanism, can drive the moving seat 3232e to move the clamping assembly 321 and the powder injection rotating assembly 322 vertically in a third direction.

[0215] With the combined action of the first powder injection moving component 3231, the second powder injection moving component 3232 and the third powder injection moving component 3233, the clamping assembly 321 and the powder injection rotating assembly 322 can move along the first direction, the second direction and the third direction respectively.

[0216] In one embodiment, such as Figure 11As shown, the weighing mechanism 5 includes a weighing element 51 and a protective cover 52. The protective cover 52 is disposed outside the weighing element 51, and the appliance 20 is disposed on the weighing element 51 and located between the weighing element 51 and the protective cover 52.

[0217] The weighing device 51 can be a balance with an accuracy of -0.1mg to +0.1mg, or an electronic balance with an accuracy of 0.01mg. The apparatus 20 is placed on the weighing device 51, and the weight of the solid or liquid raw material placed inside is read. The amount of solid and / or liquid raw material used is calibrated in real time. After feedback from the weighing device 51, the dispensing speed of the powder dispensing head 332 is adjusted to ensure the accuracy of material dispensing.

[0218] The protective cover 52 is a hollow structure. The protective cover 52 covers the outside of the weighing component 51, so that a relatively closed space is formed between the weighing component 51 and the protective cover 52. When the instrument 20 is placed inside the protective cover 52, the protective cover 52 can isolate the external atmosphere and play a role in windproofing and anti-static, so as to prevent external air and impurities from affecting the weighing process.

[0219] Among them, such as Figure 11 As shown, the protective cover 52 is provided with a positioning through hole 521, and the powder storage tank 33 is at least partially inserted through the positioning through hole 521.

[0220] Before powder injection, the instrument 20 is placed inside the protective cover 52 and is positioned corresponding to the positioning through hole 521. The positioning through hole 521 serves to initially position the instrument 20. During powder injection, the powder injection mechanism 32 grabs the powder storage tank 33 and moves it above the protective cover 52. Then, the powder storage tank 33 is placed inside the positioning through hole 521, which positions the powder storage tank 33. Under the positioning effect of the positioning through hole 521, the solid raw materials in the powder storage tank 33 are accurately injected into the instrument 20, thereby ensuring the accuracy of powder injection into the powder storage tank 33.

[0221] In one embodiment, such as Figure 12 As shown, the carbon-based catalyst preparation apparatus also includes a capping mechanism 6, which includes a capping platform 61, a capping clamping assembly 62, and a capping assembly 63. The capping platform 61 is used to support the second device 24, the capping clamping assembly 62 is used to clamp the second device 24, and the capping assembly 63 is configured to rotate the cap 242 so that the cap 242 is selectively applied to the open end.

[0222] The capping platform 61 provides support for the second device 24. The second device 24 can be placed on the capping platform 61 alone, or the second device 24 with the base 25 can be placed on the capping platform 61 together.

[0223] The capping clamping assembly 62 clamps the second instrument 24 to fix its position and prevent the main body 241 from shifting when the capping assembly 63 screws on the cap 242. The capping assembly 63 screws on the cap 242 of the second instrument 24 to open the opening end of the second instrument 24, so that the powder injection mechanism 32 can inject solid raw materials through the opening end of the second instrument 24.

[0224] like Figure 12 As shown, the capping clamping assembly 62 includes a first clamping drive source 621, a fixing block 622, and a clamping block 623. The first clamping drive source 621 may be a clamping cylinder. The first clamping drive source 621 is mounted on the capping platform 61. The fixing block 622 is fixedly disposed relative to the capping platform 61. The output end of the first clamping drive source 621 is connected to the clamping block 623. The first clamping drive source 621 can drive the clamping block 623 to move toward or away from the fixing block 622.

[0225] The second device 24 with base 25 is placed between the fixing block 622 and the clamping block 623. The first clamping drive source 621 drives the clamping block 623 to move toward the fixing block 622 and abut against the base 25. Under the cooperation of the fixing block 622 and the clamping block 623, the position of the base 25 is fixed.

[0226] In one embodiment, such as Figure 12 As shown, the capping clamping assembly 62 also includes a second clamping drive source 624 and clamping arms 625. The second clamping drive source 624 may be a clamping cylinder. The second clamping drive source 624 can drive the two clamping arms 625 to move closer to or further away from each other. Under the driving action of the second clamping drive source 624, the two clamping arms 625 clamp the second device 24, preventing the second device 24 from moving when the capping assembly 63 screws on the cap 242, thus facilitating the capping assembly 63 to perform opening or closing operations.

[0227] like Figure 12 As shown, the capping clamping assembly 62 also includes a clamping adjustment drive source 626 and a clamping seat 627. The clamping adjustment drive source 626 may be a cylinder or the like. The output end of the clamping adjustment drive source 626 is connected to the clamping seat 627. The clamping seat 627 is used to install a second clamping drive source 624. The clamping adjustment drive source 626 can drive the clamping seat 627 to move toward or away from the capping platform 61 to adjust the position of the second clamping drive source 624 and the clamping arm 625 to adapt to the second tool 24 of different sizes and specifications, and to ensure the positional stability of the second tool 24 when capping.

[0228] In one embodiment, such as Figure 12As shown, the capping assembly 63 includes a capping drive 631 and a capping member 632. The capping member 632 has a groove for accommodating the cap 242 of the second appliance 24, and the inner wall shape of the groove is adapted to the outer wall of the cap 242. The capping drive 631 may be a rotary motor, and its output end is connected to the capping member 632. The capping drive 631 can drive the capping member 632 to rotate, which in turn drives the cap 242 to rotate. By screwing the cap 242, the cap can be opened or closed.

[0229] In one embodiment, such as Figure 12 As shown, the capping mechanism 6 also includes a capping adjustment assembly 64, which is connected to the capping assembly 63. The capping adjustment assembly 64 is used to adjust the position of the capping assembly 63 so that the capping assembly 63 can be aligned with the cap 242 of the second appliance 24. The capping adjustment assembly 64 includes a capping adjustment member 641 and an adjustment seat 642. The capping adjustment member 641 can be a lifting motor or a lifting cylinder. The output end of the capping adjustment member 641 is connected to the adjustment seat 642. The adjustment seat 642 is used to install the capping drive member 631 of the capping assembly 63. The capping adjustment member 641 can drive the adjustment seat 642 to move up and down in a third direction to adjust the position of the capping assembly 63 relative to the second appliance 24, facilitating the capping assembly 63 to screw on the cap 242 of the second appliance 24.

[0230] In one embodiment, such as Figure 13 As shown, the carbon-based catalyst preparation apparatus further includes a second mixing mechanism 8, which includes a rotary table 81, a fixing component 82, and a mixing drive component 83. The rotary table 81 is used to support the second apparatus 24. The fixing component 82 is disposed on the rotary table 81 and is used to fix the second apparatus 24. The output end of the mixing drive component 83 is connected to the rotary table 81, and the mixing drive component 83 can drive the second apparatus 24 to rotate through the rotary table 81 to mix the mixture of solid raw materials in the second apparatus 24.

[0231] The mixing drive assembly 83 drives the rotary table 81 to rotate, which in turn drives the second container 24 to rotate synchronously. The centrifugal force generated by the rotation causes the solid raw material mixture inside the second container 24 to move violently. Under the action of centrifugal force, the solid raw material mixture collides, rubs, and tumbles with each other, achieving uniform dispersion of the solid raw material mixture and thus improving the mixing uniformity of the solid raw material mixture.

[0232] The second device 24 is fixed by the fixing component 82 to prevent the second device 24 from shifting or shaking due to centrifugal force during rotation, thereby preventing the solid raw materials inside the second device 24 from spilling out and reducing raw material loss.

[0233] The rotating platform 81 has a rectangular parallelepiped shape and multiple sides for supporting multiple second instruments 24. There are multiple fixing components 82, which are correspondingly arranged on the multiple sides and fix the multiple second instruments 24. The mixing process of multiple second instruments 24 can be realized by using a mixing drive component 83. While ensuring the uniformity of mixing, it can also save preparation time and improve the preparation and production efficiency.

[0234] In one embodiment, such as Figure 13 As shown, the mixing drive assembly 83 includes a mixing drive component 831, a mixing drive wheel 832, and a mixing driven wheel 833. The mixing drive component 831 may be a rotary motor. The output end of the mixing drive component 831 is connected to the mixing drive wheel 832. A mixing conveyor belt (not shown in the figure) is wound around the mixing drive wheel 832 and the mixing driven wheel 833. The mixing driven wheel 833 is connected to the rotary table 81 through a connecting shaft.

[0235] After the second apparatus 24 is placed on the rotary table 81 and fixed by the fixing assembly 82, the mixing drive 831 drives the mixing drive wheel 832 to rotate, which in turn drives the mixing driven wheel 833 to rotate and the mixing transmission belt to move. As the mixing driven wheel 833 rotates, it drives the rotary table 81 to rotate through the connecting shaft, thereby providing the rotational centrifugal force required for mixing the second apparatus 24 placed on the rotary table 81.

[0236] In one embodiment, such as Figure 13 As shown, the fixing assembly 82 includes a fixing base 821, an adjusting member 822, and a push block 823. The fixing base 821 is mounted on the rotary table 81. The adjusting member 822 can be a screw. The end of the adjusting member 822 is connected to the push block 823. The adjusting member 822 passes through the fixing base 821 and can move relative to the fixing base 821. By turning the adjusting member 822, the adjusting member 822 can drive the push block 823 to move relative to the fixing base 821, so that the push block 823 abuts against the second device 24 to fix the second device 24, ensuring the positional stability of the second device 24 relative to the rotary table 81 and preventing the second device 24 from shifting position during rotation.

[0237] In one embodiment, such as Figure 13 As shown, the fixing component 82 also includes an elastic element 824, which may be a cylindrical spring or the like. The elastic element 824 is sleeved on the outside of the adjusting component 822. The two ends of the elastic element 824 abut against the fixing seat 821 and the push block 823. The elastic element 824 plays a buffering role to prevent the push block 823 from rigidly abutting against the second device 24, which could lead to damage to the second device 24.

[0238] In one embodiment, such as Figure 14As shown, the carbon-based catalyst preparation apparatus also includes a cover opening mechanism 9. If the solid raw material mixture in the second vessel 24 needs to be transferred to the reactor vessel 26, since the reactor vessel 26 is covered with a dust cover 273, the transfer mechanism 11 grabs the reactor vessel 26 with the support component 27 and moves it to the cover opening mechanism 9. The cover opening mechanism 9 can open the dust cover 273, so that the reactor vessel 26 is in an open state, which makes it easy to pour the solid raw material mixture in the second vessel 24 into the reactor vessel 26.

[0239] The opening mechanism 9 includes a first support platform 91, a second support platform 92, and an opening component 93. The first support platform 91 is used to support the support component 27 and the reactor 26. The opening component 93 can adsorb the dust cover 273 of the support component 27 and transfer the dust cover 273 to the second support platform 92.

[0240] The opening assembly 93 includes an opening moving component 931 and an adsorption component 932. The opening moving component 931 is connected to the adsorption component 932 and moves along a first direction, a second direction, or rotates relative to the first support platform 91 to adjust the position of the adsorption component 932 relative to the first support platform 91, facilitating the adsorption component 932 to grasp the dust cover 273. The adsorption component 932 includes a vacuum generator and a suction cup. The vacuum generator is connected to the suction cup and can extract air from the suction cup, creating a negative pressure for adsorbing the dust cover 273.

[0241] In one embodiment, such as Figure 15 As shown, the reaction mechanism 7 includes a tubular furnace 7b and a reactor 26 for carrying a mixture of solid raw materials in a second apparatus 24. The reactor 26 is disposed in the tubular furnace 7b to generate graphylene products in the tubular furnace 7b.

[0242] Among them, the tube furnace 7b includes a heating and cooling module, the heating rate of which is approximately 0.2 to 20℃ / min, and the temperature range of the heating and cooling module is room temperature to 2200℃.

[0243] The tubular furnace 7b also includes a gas path control module with a flow rate of approximately 0-1000ccm. The gas path control module can switch between inert gases (such as Ar) and reducing gases (such as H2).

[0244] The tube furnace 7b includes a vacuum pump to ensure the vacuum level inside the tube furnace 7b, with a vacuum level range of approximately -0.2 MPa to atmospheric pressure, thereby ensuring calcination in an oxygen-free environment.

[0245] By precisely controlling the calcination conditions such as the heating and cooling modules, gas path control module, and vacuum pump, the graphylene product can be successfully synthesized, and the controllable coordination between the carbon substrate and metal single atoms can also be achieved.

[0246] In one embodiment, such as Figure 16 As shown, the transfer mechanism 11 includes a robotic arm 110 and a robotic gripper 111. The robotic arm 110 is connected to the robotic gripper 111. The robotic arm can drive the robotic gripper 111 to move. The robotic gripper 111 is used to grasp the device 20, realizing intermediate transfer operations in the processes of solid raw material addition, mixing, calcination reaction and discharge, so that each process does not need to wait and shortens the overall preparation time.

[0247] The robotic arm 110 has a repeatability of approximately ±0.1 mm. The robotic arm 110 has a degree of freedom of movement along the first direction, the second direction, and the third direction, and a degree of freedom of rotation around the first direction, the second direction, and the third direction, respectively, to increase the gripping range of the robotic gripper 111.

[0248] The operation process of the carbon-based catalyst preparation apparatus provided in this embodiment in solid mixing mode is as follows:

[0249] Solid raw materials are added and stored in powder storage tank 33;

[0250] The transfer mechanism 11 is used to transport the second instrument 24 to the weighing component 51 of the weighing mechanism 5, and the protective cover 52 is placed over the outside of the weighing component 51.

[0251] The solid conveying mechanism 3 uses the clamping component 321 to grab the powder storage tank 33, and the powder injection moving component 323 drives the powder storage tank 33 to move and place it in the positioning through hole 521 of the protective cover 52. The powder injection rotating component 322 drives the stirring component 333 in the powder storage tank 33 to perform spiral stirring, so that the solid raw material is injected into the second device 24. The weighing component 51 reads the powder injection amount and provides real-time feedback and calibration of the injection amount. The above operation is repeated to complete the injection process of different solid raw materials.

[0252] The protective cover 52 is opened using the transfer mechanism 11 and the second instrument 24 is taken out. The transfer mechanism 11 then transfers the second instrument 24 to the second mixing mechanism 8 to mix the solid raw materials evenly.

[0253] After being mixed by the second mixing mechanism 8, the transfer mechanism 11 transfers the second apparatus 24 to the tube furnace 7b for high-temperature calcination, or pours the solid mixture in the second apparatus 24 into the reactor apparatus 26, and transfers the reactor apparatus 26 to the tube furnace 7b for high-temperature calcination.

[0254] After cooling to room temperature, the second device 24 or the reactor device 26 is taken out using the transfer mechanism 11 to complete the preparation of the graphdiyne product.

[0255] The carbon-based catalyst preparation apparatus provided in this embodiment features a weighing mechanism 5 with high precision weighing element 51, ensuring that the error of solid raw materials is <0.01% and batch consistency reaches 99%. The gas path, temperature, and vacuum parameters of the tubular furnace 7b are linked in real time, achieving closed-loop control throughout the entire process and preventing precursor oxidation and deterioration. The calcination, mixing, and charging processes operate independently, enabling efficient parallel operation and improving equipment utilization. For example, equipment utilization can be increased by more than 50%, and daily output can be more than 20 times that of manual operation. Furthermore, the modular design allows for rapid adjustment of calcination programs, gas types, and mixing parameters, and can be extended to the preparation of materials such as MOFs and COFs, achieving flexible adaptation.

[0256] The carbon-based catalyst preparation apparatus provided in this embodiment also has the following advantages:

[0257] 1) Energy catalysis: 1. Mass production of carbon-supported single-atom catalysts (such as Fe-NC and Co-NC) for use in oxygen reduction reaction (ORR) and hydrogen production by water electrolysis (HER) in fuel cells. 2. High-throughput screening of highly active catalysts to promote the industrialization of CO2 electrochemical reduction to methanol, ethylene, etc.

[0258] 2) Environmental remediation: 1. Prepare highly efficient heterogeneous catalysts (such as Pt1 / C, Pd1 / C) for the catalytic oxidation of VOCs and the degradation of organic matter in wastewater. 2. Develop metal single-atom catalysts to promote the pyrolysis and gasification of biomass to produce high-value-added chemicals and realize the resource utilization of solid waste.

[0259] 3) In terms of integrating scientific research with industrialization: 1. Rapidly verify the coordination effects of different metals (Fe, Co, Ni) with carbon substrates, accelerate catalyst development cycles, and achieve high-throughput screening processes. 2. The equipment can be upgraded to connect to industrial production lines, achieving pilot-scale amplification.

[0260] 4) Intelligent Upgrades: 1. Integrate machine learning algorithms to optimize parameters such as calcination temperature and gas ratio based on catalyst performance data. 2. Build virtual equipment models to simulate the reaction process in real time, reducing trial-and-error costs.

[0261] 5) Green and environmentally friendly aspects: 1. Adopt low-carbon processes and develop low-temperature calcination procedures (<800℃) to reduce energy consumption and carbon emissions.

[0262] 2. It can be used as a carbon precursor for industrial waste (such as waste plastics and biochar), enabling waste recycling and resource recycling.

[0263] In one embodiment, such as Figure 17As shown, the liquid phase transport mechanism 4 can be mounted on the base 1 or on the powder injection worktable 34. The liquid phase transport mechanism 4 is made of a material resistant to organic reagent corrosion, such as a material resistant to corrosion and swelling of pyridine and toluene.

[0264] In one embodiment, such as Figure 17 As shown, the liquid phase delivery mechanism 4 includes a storage tank 41, a platform 42, an injection head 43, and an injection pump (not shown in the figure). The storage tank 41 is used to store liquid raw materials, the platform 42 is used to support the device 20, the injection head 43 is connected to the storage tank 41, and the injection pump can deliver the liquid raw materials in the storage tank 41 to the injection head 43, so that the injection head 43 can add liquid raw materials to the device 20 located on the platform 42.

[0265] The storage tank 41 can be an alternative to a raw material container. The storage tank 41 is placed below the base 1, without occupying the upper space of the base 1, and its concealed location beneath the base 1 contributes to its aesthetic appeal. The storage tank 41 is made of a material resistant to organic solvents, such as fluororubber. The volume of the storage tank 41 is approximately 2L to 3L. The storage tank 41 is used to store organic reagents such as pyridine and toluene.

[0266] The platform 42 has a cylindrical shape and is equipped with a liquid injection tank 421 for placing the device 20. For example, the inner wall shape of the liquid injection tank 421 matches the outer wall shape of the first device 23 to ensure the positional stability of the first device 23 when liquid is injected into the platform 42.

[0267] The single-dose accuracy of the injection pump is approximately -0.1 mg to +0.1 mg.

[0268] The injection head 43 can be connected to the storage tank 41 via a liquid delivery line, allowing the operator to hold the injection head 43 and inject liquid into the instrument 20. Alternatively, the injection head 43 can be mounted on the powder injection workbench 34 via an injection rack, suspending the injection head 43 directly above the platform 42. When injection is needed, one end of the injection line is connected to the storage tank 41, and the other end is connected to the injection head 43. Because the injection head 43 is fixedly mounted on the injection rack, the workload of the operator is reduced, and the injection production efficiency is improved.

[0269] In one embodiment, such as Figure 18 As shown, the reaction mechanism 7 includes a microwave reaction mechanism 7a, and a first device 23 is disposed in the microwave reaction mechanism 7a, so that the mixture of solid raw materials and liquid raw materials generates graphylene product in the microwave reaction mechanism 7a.

[0270] With this configuration, the microwave reaction mechanism 7a emits microwaves that act on the mixture of solid and liquid raw materials. The microwaves can be high-frequency electromagnetic waves, causing the molecules in the mixture to vibrate at high frequencies and generate heat, achieving an internal heating mode with good heating uniformity. Simultaneously, using this microwave heating method, the mixture can quickly reach the required reaction temperature, shortening the reaction time, improving the preparation efficiency of graphetrazine products, and meeting the needs of high-throughput preparation.

[0271] In one embodiment, such as Figure 18 As shown, the microwave reaction mechanism 7a includes a reaction chamber 71 and a microwave generator (not shown in the figure). The microwave generator is located inside the reaction chamber 71 and is used to release electromagnetic waves into the reaction chamber 71.

[0272] The reaction chamber 71 provides a sealed environment for the microwave generator, preventing electromagnetic waves from leaking out during the heating process and causing energy loss, and ensuring that the electromagnetic waves can be concentrated on the solid-liquid mixture in the first device 23, thereby improving energy utilization.

[0273] The microwave generator features constant power and temperature characteristics, with a power range of 0-900W and a temperature range between room temperature and 200℃. The microwave generator can directly release microwaves into the reaction chamber 71. Within the enclosed space of the reaction chamber 71, the microwaves are reflected and superimposed, forming a uniform microwave field. This ensures that the solid-liquid mixture in different areas of the first apparatus 23 can uniformly absorb microwave energy, avoiding localized overheating or insufficient heating due to uneven microwave distribution.

[0274] In one embodiment, such as Figure 18 As shown, the reaction chamber 71 includes a chamber body 71 and a door 72. The chamber body 71 is provided with an opening 710, and the door 72 is rotatably connected to the chamber body 71 for selectively sealing the opening 710.

[0275] When a reaction is required, the chamber door 72 is opened to allow the transfer mechanism 11 to carry the first device 23 through the opening 710 and place it into the chamber 71. Then, the chamber door 72 is closed, sealing the opening 710 to form a closed space inside the reaction chamber 71 and prevent electromagnetic wave leakage.

[0276] In one embodiment, the microwave reaction mechanism 7a further includes a door assembly 75, which includes a door drive source 751 and a blocking member 752. The door drive source 751 may be a cylinder, and the door drive source 751 can drive the blocking member 752 to move, so that the blocking member 752 selectively abuts against the door 72.

[0277] Before the reaction, the door-blocking drive source 751 drives the blocking member 752 to move towards the door 72. The blocking member 752 abuts against the door 72 to lock the position of the door 72, keeping the opening 710 of the container 71 open. After the first apparatus 23 is transferred into the container 71 via the transfer mechanism 11, the door-blocking drive source 751 drives the blocking member 752 to move away from the door 72. The blocking member 752 disengages from the door 72, releasing the position lock of the door 72, causing the door 72 to rotate relative to the container 71 and seal the opening of the container 71. In this way, locking and unlocking of the door 72 can be achieved automatically without manual intervention, improving preparation efficiency.

[0278] In one embodiment, such as Figure 18 As shown, the microwave reaction mechanism 7a also includes a temperature detection component 72. The reaction chamber 71 is provided with a detection through hole 711, which provides clearance space for the temperature detection component 72. The temperature detection component 72 can pass through the detection through hole 711 and extend into the first device 23 to detect the temperature of the solid-liquid mixture in the first device 23.

[0279] Among them, such as Figure 19 As shown, the temperature detection assembly 72 includes a detection lifting component 721 and a detection element 722. The output end of the detection lifting component 721 is connected to the detection element 722. The detection lifting component 721 can drive the detection element 722 to move up and down, so that the detection element 722 passes through the detection through hole 711 and extends into the first device 23. The detection element 722 is used to detect the temperature of the solid-liquid mixture in the first device 23 to regulate the reaction process. The detection element 722 can be a temperature sensor, and it is made of a corrosion-resistant material. The temperature detection range of the detection element 722 is greater than 0 to 1200°C.

[0280] Before the reaction begins, the detection lifting component 721 drives the detection element 722 to rise in a third direction, facilitating the transfer mechanism 11 to place and position the first device 23 inside the reaction chamber 71, preventing the detection element 722 from obstructing or interfering with the first device 23. At the start of the reaction, the detection lifting component 721 drives the detection element 722 to descend in a third direction, allowing it to extend into the first device 23 to detect the temperature of the solid-liquid mixture. Furthermore, depending on the size and specifications of the first device 23, the height of the detection element 722 can be adjusted by the detection lifting component 721 to ensure that the detection element 722 can smoothly extend into the first device 23 and contact the solid-liquid mixture, improving the adaptability and versatility of the microwave reaction mechanism 7a for different application scenarios.

[0281] Among them, such as Figure 19As shown, the detection lifting component 721 includes a detection drive component 7211, a detection drive wheel 7212, a detection driven wheel 7213, a detection conveyor belt 7214, and a detection frame 7215. The detection drive component 7211 may be a rotary motor. The output end of the detection drive component 7211 is connected to the detection drive wheel 7212. The detection drive wheel 7212 and the detection driven wheel 7213 are arranged along a third direction. The detection conveyor belt 7214 is wound around the detection drive wheel 7212 and the detection driven wheel 7213. The detection conveyor belt 7214 is connected to the detection frame 7215 through a fixing member. The detection frame 7215 is used to install the detection component 722.

[0282] The detection drive component 7211 drives the detection drive wheel 7212 to rotate, which in turn drives the detection driven wheel 7213 to rotate and the detection conveyor belt 7214 to move. As the detection conveyor belt 7214 moves, the detection component 722 is driven to move up and down along a third direction through the detection frame 7215.

[0283] In one embodiment, such as Figure 19 As shown, the temperature detection assembly 72 also includes a cover plate 723, and the detection element 722 passes through the cover plate 723. The cover plate 723 is used to seal the detection through hole 711.

[0284] By sealing the detection through-hole 711 with the cover plate 723, the reaction chamber 71 has a relatively closed sealed space. The microwaves generated by the microwave generator will not leak out through the detection through-hole 711, and the electromagnetic waves can be concentrated inside the reaction chamber 71, thereby improving the preparation efficiency of the graphdiyne product.

[0285] In one embodiment, such as Figures 19-20 As shown, the microwave reaction mechanism 7a also includes a cleaning component 73, which is disposed outside the reaction chamber 71 and is used to clean the detection component 722.

[0286] Before the detection element 722 is inserted into the first apparatus 23, it is first cleaned by the cleaning component 73 to prevent the detection element 722 from carrying the solid-liquid mixture from the previous test into the solid-liquid mixture of the current test, thus ensuring the detection accuracy and improving the purity of the graphylene product. After the detection element 722 is inserted into the solid-liquid mixture in the first apparatus 23, the solid-liquid mixture may be corrosive. If the solid-liquid mixture adheres to the detection element 722 for a long time, it will affect the detection accuracy of the detection element 722. Cleaning the detection element 722 with the cleaning component reduces the residue of corrosive substances such as solid-liquid mixture and extends the service life of the detection element 722.

[0287] In one embodiment, such as Figure 20As shown, the cleaning assembly 73 includes a cleaning platform 731 with multiple receiving chambers spaced apart. These chambers are used to hold different cleaning agents. The spaced-apart chambers prevent cross-contamination caused by mixing different cleaning agents, which would affect the cleaning effect. They also facilitate the individual replacement of different cleaning agents.

[0288] The plurality of accommodating cavities include a first accommodating cavity 7311 and a second accommodating cavity 7312. The first accommodating cavity 7311 is used to accommodate organic solvents, and the second accommodating cavity 7312 is used to accommodate deionized water.

[0289] Depending on the degree of contamination or the type of raw material of the test piece 722, the type of cleaning agent can be selected or the combination can be adjusted. The test piece 722 can be placed only in the first receiving cavity 7311 or only in the second receiving cavity 7312; or, the test piece 722 can be placed in the first receiving cavity 7311 and the second receiving cavity 7312 in sequence, solving the problem that a single cleaning agent cannot thoroughly clean and improving the degree of cleaning.

[0290] In one embodiment, such as Figure 20 As shown, the cleaning assembly also includes a fan 732, and the cleaning station 731 is also provided with an air-cooled cavity 7313, with the air outlet of the fan 732 connected to the air-cooled cavity 7313.

[0291] After the test piece 722 is cleaned with the cleaning agent in the receiving cavity, the test piece 722 is placed in the air-cooling cavity 7313. The fan 732 delivers airflow into the air-cooling cavity 7313 through the air outlet, which can air-cool and dry the cleaned test piece to remove the cleaning agent adhering to the surface of the test piece 722 and improve the thoroughness of cleaning.

[0292] In one embodiment, such as Figure 20 As shown, the microwave reaction mechanism 7a also includes a switching component 74, which is connected to the temperature detection component 72. The switching component 74 can drive the temperature detection component 72 to rotate, so that the detection element 722 is selectively disposed between the detection through hole 711 and the cleaning component 73.

[0293] Before the reaction begins, the switching component 74 drives the detector 722 to rotate to the detection through hole 711, so that the detector 722 extends into the first device 23 to complete the temperature measurement process. After the reaction is completed, the detector 722 does not need to be manually disassembled. The switching component 74 can directly rotate the detector 722 to the cleaning component 73 for cleaning. The whole process does not need to be interrupted, which shortens the cleaning and resetting time of the detector 722, improves the preparation efficiency, and thus meets the high-throughput preparation requirements.

[0294] The switching component 74 can drive the detection element 722 to rotate, so that the detection element 722 can be selectively disposed in multiple receiving cavities and air-cooling cavities 7313, so as to switch between the detection through hole 711, the first receiving cavity 7311, the second receiving cavity 7312 and the air-cooling cavity 7313.

[0295] After the reaction is complete and the detector 722 detaches from the detection through-hole 711, the switching assembly 74 rotates the detector 722 away from the detection through-hole 711. The switching assembly 74 then sequentially feeds the detector 722 into the first receiving cavity 7311 and the second receiving cavity 7312 for cleaning, before transferring it to the air-cooling cavity 7313 for drying. Finally, it is reset to the detection through-hole 711 to await the next temperature measurement. The entire cleaning and reset process requires no manual intervention, reducing the processing time of the detector 722 and thus meeting the needs of high-throughput preparation.

[0296] In one embodiment, such as Figure 21 As shown, the carbon-based catalyst preparation apparatus also includes a first mixing mechanism 10, which is used to carry the first apparatus 23 and is capable of mixing the mixture of solid raw materials and liquid raw materials within the first apparatus 23.

[0297] The first mixing mechanism 10 can be a magnetic stirring mechanism, which has heating and stirring functions. The temperature range of the magnetic stirring mechanism is room temperature to 200℃, and the stirring speed is approximately 0-2000 rpm. The magnetic stirrer provides real-time feedback on temperature control and speed to achieve homogenization of solid-liquid mixing.

[0298] The solid-liquid mixture in the first apparatus 23 is stirred by the first mixing mechanism 10 to ensure the uniformity of the mixing of the solid and liquid raw materials. The solid-liquid mixture after being mixed by the first mixing mechanism 10 is then transferred to the microwave reaction mechanism 7a by the transfer mechanism 11 to further improve the reaction effect of the graphylene product.

[0299] The working process of the carbon-based catalyst preparation apparatus provided in this embodiment in solid-liquid mixing mode is as follows:

[0300] Solid raw materials are added and stored in powder storage tank 33;

[0301] The first instrument 23 is transported to the weighing component 51 of the weighing mechanism 5 using the transfer mechanism 11, and a protective cover 52 is placed over the outside of the weighing component 51.

[0302] The solid phase conveying mechanism 3 uses the clamping component 321 to grab the powder storage tank 33, and the powder injection moving component 323 drives the powder storage tank 33 to move and place it in the positioning through hole 521 of the protective cover 52. The powder injection rotating component 322 drives the stirring component 333 in the powder storage tank 33 to perform spiral stirring, so that the solid raw material is added into the first device 23. The weighing component 51 reads the powder injection amount and provides real-time feedback and calibration of the injection amount.

[0303] The first device 23 is placed on the platform 42 of the liquid phase conveying mechanism 4 using the transfer mechanism 11. The liquid pump delivers the liquid raw material in the storage tank 41 to the injection head 43 according to the single injection volume, and adds the liquid raw material into the first device 23 through the injection head 43.

[0304] The transfer mechanism 11 transfers the first instrument 23 to the first mixing mechanism 10 for heating and mixing the solid-liquid mixture;

[0305] After being mixed by the first mixing mechanism 10, the transfer mechanism 11 transfers the first device 23 to the reaction chamber 71 of the microwave reaction mechanism 7a, and uses the detection element 722 to detect the temperature in real time to regulate the reaction process.

[0306] The solution treated by the microwave reaction mechanism 7a is then subjected to centrifugation, freeze-drying, and other steps to obtain graphylene powder, thus completing one cycle of preparation.

[0307] The carbon-based catalyst preparation apparatus provided in this embodiment achieves high-precision control, with weighing, liquid addition, and positioning accuracy all reaching ±0.1 level, ensuring batch stability of the graphylene product. For example, the purity of the graphylene product is >98%, and the batch variation is <1%. The transfer mechanism 11 facilitates transfer between various processes, achieving full automation and improving production efficiency; for example, daily output is more than 10 times higher than manual operation. The modular design allows for flexible adjustment of parameters such as temperature, power, and formulation to adapt to different material preparation needs.

[0314] Of course, the carbon-based catalyst preparation apparatus provided in this embodiment can also use different liquid raw materials to achieve liquid-liquid mixing in order to prepare graphyne product. The specific working process is as follows:

[0315] The first device 23 is placed on the platform 42 of the liquid phase conveying mechanism 4 using the transfer mechanism 11. The liquid pump delivers the liquid raw material in the storage tank 41 to the injection head 43 according to the single injection volume, and adds the liquid raw material into the first device 23 through the injection head 43. Different liquid raw materials are delivered through separate injection pipelines.

[0316] The transfer mechanism 11 transfers the first device 23 into the microwave reaction mechanism 7a, and monitors the temperature in real time through the detection element 722 to regulate the reaction process;

[0317] After the reaction is complete, the solution is cooled to room temperature and removed, thus completing the automated microwave preparation of the specified solution product.
