Description

Technical Field

[0001] The present invention relates to the technical field of powder preparation, and specifically to a preparation device and method for a high-performance composite powder material. Background Art

[0002] Copper is widely used as a structural material in engineering applications due to its excellent chemical stability, wear resistance, plasticity, and thermal and electrical conductivity. However, copper has low strength, especially under high-temperature conditions, and its mechanical properties cannot meet the requirements of applications. These disadvantages greatly limit its practical applications in many fields. Graphene is a two-dimensional structural material composed of carbon atom hybridization, which has excellent physical and mechanical properties. By combining the two to prepare a graphene copper-based composite material, while maintaining the good thermal and electrical conductivity of the copper matrix itself, the mechanical properties of the matrix material can be significantly improved.

[0003] In the production process of graphene copper-based composite materials, mainly by mixing vaporized copper vapor with a carbon source gas, so that graphene can coat on the copper vapor. Specifically, the carbon source gas realizes the production of graphene copper-based composite materials by impacting and mixing with the carbon source gas in the reaction chamber.

[0004] In the process of mixing the carbon source gas and copper vapor, in order to improve the coating effect of graphene on copper vapor, it is often necessary to spray the carbon source gas and copper vapor multiple times to improve the fusion effect. However, the space in the reaction chamber is large, resulting in a poor collision effect between graphene and copper vapor. Even with multiple sprays, the positive effect of graphene coating on copper vapor is not significant, that is, the effect achieved while consuming energy is average, affecting the production quality of graphene copper-based composite materials.

[0031] A method for preparing a high-performance composite powder material using the preparation device comprises the following steps:

[0032] Step 1: introducing protective gas into the reaction chamber until the air in the reaction chamber is exhausted;

[0033] Step 2: The first power structure controls the action of the suction component to form a negative pressure in the reaction chamber. When the negative pressure reaches a preset value, the follower component controls the action of the energy storage component and drives the valve to open through the transmission structure.

[0038] Step 7: Control the flip plate to reset, and then collect the powder.

[0039] Compared with the prior art, the beneficial effects of the present invention are:

[0040] By providing the flip plate, nozzle, suction assembly, first power structure and second power structure, when the protective gas flows back into the reaction chamber, two circulating airflows can be formed under the guidance of the flip plate. On the one hand, this can improve the mixing effect of the carbon source gas and the copper vapor. On the other hand, it can also make the copper vapor coated with graphene circulate, and reduce the agglomeration phenomenon through collision. At the same time, it can also shorten the circulating flow path of the airflow. When the airflow is blown to the nozzle at the same speed, the duration of the airflow circulating is longer, ensuring the mixing effect. And the flip plate is shaped like dividing the reaction chamber into two chambers, reducing the space for the carbon source gas and the copper vapor to move, and can improve the collision probability of the carbon source gas and the copper vapor, further ensuring the mixing effect between the two and improving the production quality of the powder;

[0041] By providing the valve, vertical plate, energy storage assembly and follower assembly, the real-time pressure value in the reaction chamber can be detected. Compared with the existing flow sensors or pressure sensors, it will not be affected by graphene powder and the working state is more stable. And the rapid opening and closing of the valve can make the gas volume of the carbon source gas entering the reaction chamber easier to be accurately controlled, avoiding the decrease in powder quality caused by too little carbon source gas or the agglomeration phenomenon of the powder caused by too much carbon source gas.

Detailed implementation manners

[0052] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0053] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, which can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0054] Please refer to Figures 1 to 9 , in the embodiment of the present invention, a preparation device for a high-performance composite powder material includes: a reaction chamber 2, a turning plate 23, a nozzle 24, a suction assembly, a first power structure, and a second power structure.

[0055] The reaction chamber 2 is disposed on the equipment platform 1, and a first discharge pipe 4 and a second discharge pipe 5 are disposed in the reaction chamber 2. The first discharge pipe 4 is connected to a high-energy beam generator 3 disposed on the reaction chamber 2;

[0056] The suction assembly is connected to two groups of the nozzles 24, and a contact wheel 32 is connected to the suction assembly;

[0057] The suction assembly includes a suction sleeve 36 connected to the reaction chamber 2 and communicating with two groups of the nozzles 24. Specifically, the suction sleeve 36 is connected to the nozzle 24 through a conduit 37. A second sealing plug 34 is hermetically and slidably installed in the suction sleeve 36. A telescopic shaft 33 penetrating the suction sleeve 36 is connected to the second sealing plug 34. A third spring 35 is sleeved on the telescopic shaft 33. One end of the third spring 35 is connected to the second sealing plug 34, and the other end is connected to the suction sleeve 36;

[0058] One end of the telescopic shaft 33 away from the second sealing plug 34 is connected to a connecting plate 31, and the connecting plate 31 is rotatably connected to the contact wheel 32.

[0059] In the initial state, the third spring 35 is in a compressed state. At this time, the reaction chamber 2 is filled with a protective gas (argon, nitrogen or helium). When the first power structure acts, it can cooperate with the abutting wheel 32, and the connecting plate 31 can drive the second sealing plug 34 to act through the telescopic shaft 33. At this time, the protective gas in the reaction chamber 2 can be pumped into the suction sleeve 36, so that a negative pressure state can be generated in the reaction chamber 2. Using this negative pressure, the external carbon source gas can be pumped into the reaction chamber 2 without using an additional pumping device to pump the carbon source gas, reducing the production cost of the device. Moreover, in the negative pressure state, there can be a more violent collision between the carbon source gas and the copper vapor, thereby improving the mixing degree of the two and enhancing the effect of graphene coating the copper vapor.

[0060] When the second power structure acts, it can release the abutting wheel 32. At this time, the third spring 35 can pump the protective gas in the suction sleeve 36 into the reaction chamber 2 by releasing the elastic potential energy. On the one hand, it can restore the pressure in the reaction chamber 2. On the other hand, the protective gas pumped into the reaction chamber 2 can form a tendency of circulating flow in the reaction chamber 2, so that the copper vapor not coated with graphene in the reaction chamber 2 can further flow, and there is a secondary mixing effect between the graphene and the copper vapor.

[0061] Please refer to Figures 7 to 9 , the flipping plate 23 is rotatably installed in the reaction chamber 2;

[0062] There are two groups of the nozzles 24 and they are symmetrically installed on the reaction chamber 2. The two groups of the nozzles 24 are arranged diagonally along the rotation axis of the flipping plate 23;

[0063] The first power structure is connected to the suction assembly, and a stop portion 2801 that rolls with the abutting wheel 32 is provided on the first power structure;

[0064] The first power structure includes a lifting rod 27 slidably arranged on the reaction chamber 2. A pulling rod 28 is slidably installed on the lifting rod 27. The pulling rod 28 is connected to the stop portion 2801. Specifically, the lifting rod 27 is arranged in the vertical direction of space, and the pulling rod 28 is arranged in the horizontal direction of space;

[0065] The first power structure further includes an electric telescopic rod 30 connected to the reaction chamber 2. A connecting frame 29 slidably connected to the pulling rod 28 is connected to the action end of the electric telescopic rod 30;

[0066] The second power structure is connected to the first power structure and the flipping plate 23, and can misalign the stop portion 2801 and the abutting wheel 32 when the flipping plate 23 deflects by a predetermined angle;

[0067] The second power structure includes a driving device 25 fixedly installed on the reaction chamber 2 and connected to the turning plate 23, and a follower 26 connected to the turning plate 23. A fitting shaft 2601 is provided at an eccentric position of the follower 26, and the fitting shaft 2601 is slidably engaged with a fitting groove 2701 provided on the lifting rod 27.

[0068] In the initial state, the turning plate 23 is in a vertical state. At this time, controlling the electric telescopic rod 30 to act can drive the pull rod 28 to move horizontally. Under the action of the abutting portion 2801 and the abutting wheel 32 abutting against each other, the connecting plate 31 can follow the movement of the pull rod 28, and drive the second sealing plug 34 to act through the telescopic shaft 33. While pumping the protective gas in the reaction chamber 2 into the suction sleeve 36, a negative pressure is generated in the reaction chamber 2. When the carbon source gas and the copper vapor in the reaction chamber 2 are first mixed, the driving device 25 will act and drive the turning plate 23 to deflect by a predetermined angle. At the same time, the follower 26 follows the turning of the turning plate 23, causing the fitting shaft 2601 to perform a circular motion. During this process, the fitting shaft 2601 cooperates with the fitting groove 2701 to drive the lifting rod 27 to move upward and pull the pull rod 28 upward, so that the abutting portion 2801 can be misaligned with the abutting wheel 32. At this time, the third spring 35 releases elastic potential energy and can pump the protective gas in the suction sleeve 36 back into the reaction chamber 2. Since the turning plate 23 is in an inclined state at this time, and the two groups of nozzles 24 are arranged diagonally along the rotation axis of the turning plate 23, the protective gas pumped to the nozzles 24 through the conduit 37 can act on the turning plate 23 to change the flow direction of the protective gas, thereby generating two circulating airflows in the reaction chamber 2 to perform secondary mixing on the carbon source gas and the copper vapor in the reaction chamber 2 and improve the mixing effect.

[0069] Further, in this embodiment, when the protective gas flows back into the reaction chamber 2, it can form two circulating airflows under the guidance of the turning plate 23. On the one hand, this can improve the mixing effect of the carbon source gas and the copper vapor. On the other hand, it can also make the copper vapor coated with graphene circulate and reduce the agglomeration phenomenon through collision. At the same time, it can also shorten the circulating flow path of the airflow. When the airflow is blown to the nozzles 24 at the same speed, the duration of the airflow circulating is longer, ensuring the mixing effect. And the turning plate 23 is shaped like dividing the reaction chamber 2 into two chambers, reducing the space for the carbon source gas and the copper vapor to move, and can improve the collision probability of the carbon source gas and the copper vapor, further ensuring the mixing effect between the two and improving the production quality of the powder.

[0070] Please refer to Figures 4 to 6 , a preparation device for a high-performance composite powder material, further comprising: a valve 6, a vertical plate 11, an energy storage component, and a follower component.

[0071] The valve 6 is communicated with the second discharge pipe 5, and a transmission structure capable of controlling its opening and closing is arranged on the valve 6;

[0072] The transmission structure includes a gear 7 coaxially and fixedly connected to the control shaft of the valve 6 and a guide rod 9 arranged on the valve 6. A rack plate 8 meshing with the gear 7 is arranged on the guide rod 9;

[0073] The transmission structure further includes a connecting member 10. A sliding connection portion 1002 and a vertical groove 1001 are arranged on the connecting member 10. The sliding connection portion 1002 is slidably connected to a retention groove 801 arranged on the side of the rack plate 8, and the vertical groove 1001 is in rolling fit with a first convex shaft 13 connecting the grooved pulley 12;

[0074] The vertical plate 11 is arranged on the valve 6. A connecting groove is formed on the vertical plate 11. A grooved pulley 12 is rotatably installed in the connecting groove. The grooved pulley 12 is connected to the transmission structure. Specifically, the connecting groove includes two groups of inclined grooves 1101 symmetrically arranged on the vertical plate 11, and a bending portion is arranged at the connection of the two groups of inclined grooves 1101.

[0075] In the prior art, the pumping of the carbon source gas depends on an external pumping device for transportation. In this process, the transportation volume of the carbon source gas is mainly monitored by a flow sensor built in the valve 6 or a pressure sensor built in the reaction chamber 2. However, the carbon source gas contains graphene with very small particles, so that these graphene may enter the inside of the flow sensor or the pressure sensor, causing errors in the flow sensor and the pressure sensor, thereby reducing the transportation accuracy of the carbon source gas.

[0076] In this embodiment, the extraction of the carbon source gas mainly relies on the negative pressure in the reaction chamber 2. Specifically, in the initial state, the valve 6 is in a closed state. At this time, the sprocket 12 is at one end of the inclined groove 1101. At the same time, the energy storage component has a tendency to pull the sprocket 12 towards the valve 6. In this state, the sprocket 12 has a certain effect of being limited, thereby improving the stability of the sprocket 12 in this state. When the protective gas in the reaction chamber 2 is pumped away to generate a negative pressure, the follower assembly will act and drive the sprocket 12 to move along the inclined groove 1101 towards the bent portion. At this time, the first convex shaft 13 will also cooperate with the vertical groove 1001 to drive the connecting member 10 to slide along the accommodating groove 801. At this time, the rack plate 8 can remain stationary, and the valve 6 remains in a closed state. When the negative pressure in the reaction chamber 2 reaches the preset value, the follower assembly can drive the sprocket 12 to move past the bent portion. At the same time, the connecting member 10 can abut against the side wall of one side of the accommodating groove 801. At this time, the energy storage component drives the sprocket 12 to move along the other inclined groove 1101 and makes the rack plate 8 move along the guide rod 9. At this time, the gear 7 rotates and controls the opening of the valve 6. Under the action of the negative pressure, the carbon source gas can be pumped into the reaction chamber 2. As the negative pressure in the reaction chamber 2 decreases, the follower assembly will act in the reverse direction and drive the sprocket 12 to move in the reverse direction. When the negative pressure in the reaction chamber 2 reaches the predetermined value, the sprocket 12 moves past the bent portion along the inclined groove 1101 again, so that the sprocket 12 moves in the reverse direction and resets. At this time, the gear 7 rotates in the reverse direction and can close the valve 6.

[0077] Through the above settings, under the action of the follower structure, the valve 6 has a state of being instantaneously opened and closed, improving the action speed of the valve 6 and making it easier to accurately control the amount of gas of the carbon source gas entering the reaction chamber 2.

[0078] Please refer to Figures 5 to 6 , the energy storage component is connected to the sprocket 12, and the energy storage component can make the sprocket 12 have a tendency to move towards the end of the connecting groove;

[0079] The energy storage component includes a horizontal holder 15 slidably mounted on the vertical plate 11. A horizontal groove 1501 is provided along the length direction of the horizontal holder 15. The horizontal groove 1501 is in rolling fit with the second convex shaft 14. Among them, a guiding portion 1502 is provided on the side of the horizontal holder 15, and the guiding portion 1502 is slidably connected to the vertical plate 11;

[0080] The end of the horizontal holder 15 is also slidably connected to a connecting shaft 16 provided on the vertical plate 11. A first spring 17 is sleeved on the connecting shaft 16. One end of the first spring 17 is connected to the end of the connecting shaft 16, and the other end is connected to the horizontal holder 15;

[0081] The follower assembly is connected to the reaction chamber 2 and is connected to the sprocket 12. The follower assembly can control the movement of the sprocket 12 according to the air pressure value in the reaction chamber 2;

[0082] The follower assembly includes a connecting sleeve 22 communicating with the reaction chamber 2. A first sealing plug 20 is hermetically and slidably installed in the connecting sleeve 22. A connecting rod 19 passing through the connecting sleeve 22 is connected to the first sealing plug 20. A second spring 21 is sleeved on the connecting rod 19. One end of the second spring 21 is connected to the first sealing plug 20, and the other end is connected to the side wall of the connecting sleeve 22;

[0083] A frame plate 18 is further provided at one end of the connecting rod 19 away from the first sealing plug 20. A hollow part is provided inside the frame plate 18, and the hollow part is in rolling fit with a second convex shaft 14 connecting the sprocket 12.

[0084] In the initial state, the second spring 21 is in a stretched state. When the air pressure in the reaction chamber 2 drops, the first sealing plug 20 will move towards the reaction chamber 2 in the connecting sleeve 22. At this time, the connecting rod 19 can drive the frame plate 18 to move, and thereby drive the second convex shaft 14 to move, so as to drive the sprocket 12 to roll in the inclined groove 1101. When the carbon source gas enters the reaction chamber 2, the air pressure in the reaction chamber 2 will drop again. At this time, the second spring 21 releases elastic potential energy and can pull the first sealing plug 20 to move in the reverse direction, and make the sprocket 12 move in the reverse direction, so as to realize the trigger movement of the sprocket 12 and realize the opening and closing control of the valve 6.

[0085] It should be noted that the length of the hollow part in the middle of the frame plate 18 is slightly larger than the projection length of the inclined groove 1101 on the horizontal plane, so that when the sprocket 12 moves past the bending part and moves along the inclined groove 1101 to the end, the second convex shaft 14 can be in contact with the other side wall of the hollow part, so that when the frame plate 18 moves in the reverse direction, the sprocket 12 can be immediately driven to move through the second convex shaft 14.

[0086] Through the above settings, under the action of the follower assembly, the real-time pressure value in the reaction chamber 2 can be detected. Compared with the existing flow sensors or pressure sensors, it will not be affected by graphene powder and its working state is more stable. Moreover, the rapid opening and closing of the valve 6 can make the gas volume of the carbon source gas entering the reaction chamber 2 easier to be accurately controlled, avoiding the decrease in powder quality caused by too little carbon source gas or the agglomeration phenomenon of the powder caused by too much carbon source gas.

[0087] As an embodiment of the present invention, a method for preparing a high-performance composite powder material using the preparation device as described above is also proposed, including the following steps:

[0088] Step 1: Introduce a protective gas into the reaction chamber 2 until the air in the reaction chamber 2 is exhausted;

[0089] Step 2: Control the suction assembly to act through the first power structure, so as to form a negative pressure in the reaction chamber 2. When the negative pressure reaches the preset value, the follower assembly controls the energy storage assembly to act, and drives the valve 6 to open through the transmission structure;

[0090] Step 3: The valve 6 is connected to an external carbon source gas storage tank. When the valve 6 is opened, the carbon source gas is pumped into the reaction chamber 2 by using the negative pressure in the reaction chamber 2. At the same time, the high-energy beam generator 3 vaporizes the copper powder into copper vapor and introduces it into the reaction chamber 2;

[0091] Step 4: The carbon source gas reacts with the copper vapor in the reaction chamber 2, enabling carbon to coat the copper vapor;

[0092] Step 5: When the negative pressure in the reaction chamber 2 drops to a predetermined value, the follower assembly controls the energy storage assembly to act, and drives the valve 6 to close through the transmission structure;

[0093] Step 6: The second power structure drives the turning plate 23 to deflect, and makes the stop portion 2801 misaligned with the turning plate 23. At this time, the suction assembly acts in the reverse direction to pump the protective gas into the reaction chamber 2. At this time, the copper vapor coated with carbon can circulate bidirectionally in the reaction chamber 2;

[0094] Step 7: Control the turning plate 23 to reset, and then collect the powder.
