Detailed Implementation

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this utility model can be combined with each other. The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Referring to the accompanying drawings, this utility model provides a microwave reaction apparatus for whisker preparation, including a reaction chamber 1, a microwave generating and transmitting component, a cooling system, and a main controller. A support frame 2 is disposed within the reaction chamber 1, and a container 3 for holding whisker material is detachably connected to the support frame 2. Several temperature sensors are disposed within the reaction chamber 1. The microwave generating and transmitting component includes a magnetron and a waveguide, with the waveguide positioned between the magnetron and the reaction chamber 1, transmitting the microwaves generated by the magnetron to the reaction chamber 1. The cooling system includes a cooling element disposed within the reaction chamber 1, connected to a cold source component that provides a cooling medium. The temperature sensors, magnetron, and cold source component are all electrically connected to the main controller. The main controller controls the power of the magnetron and the speed at which the cold source component provides the cooling medium to the cooling element based on the temperature information received from the temperature sensors and stored control information. This embodiment is applicable to the preparation of high-performance whiskers such as silicon carbide whiskers and alumina whiskers.

[0028] Before operation, the whisker material (precursor material) is placed in container 3, and container 3 is mounted on support frame 2, thus placing the whisker material into reaction chamber 1. The reaction device begins operation; the magnetron generates microwaves, which are transmitted to reaction chamber 1 via waveguides. Under the influence of the microwaves, the whisker material vibrates at high speed, generating heat through intermolecular friction, thus heating the whiskers. Microwave heating offers advantages such as rapid heating, high energy utilization, and uniform heating, solving the technical problems of resistance heating in existing technologies. Throughout the process, a temperature sensor monitors the internal temperature of reaction chamber 1 and the temperature of the whisker material in real time, transmitting this temperature information to the main controller. Based on the received temperature information from the sensor and stored control information, the main controller controls the power of the magnetron and the rate at which the cold source assembly provides cooling medium to the cooling elements, thereby precisely controlling the heating rate and temperature of the whisker material via microwave heating.

[0029] In this embodiment, the magnetron serves as the microwave source, with a frequency of 2.45 GHz or 915 MHz and an adjustable power range of 0.5-10 kW, a maximum power of 10 kW, and both power and frequency are adjustable. The temperature sensor can be a thermocouple sensor or an infrared thermometer. Simultaneously, the control information includes the heating temperature, heating time, and heating rate of the whisker material. During the gradual heating of the whisker material, the main controller primarily considers whether the heating rate meets the requirements. When the heating rate is lower than the set rate, the magnetron power is increased to increase the microwave heating rate of the whisker material; when the heating rate is higher than the set rate, the magnetron power is decreased to reduce the microwave heating rate of the whisker material. When the whisker material temperature reaches the set range, the main controller primarily references this temperature. When the whisker material temperature is below the set range, the power of the magnetron is increased to raise the whisker material temperature and maintain it within the set range. When the whisker material temperature is above the set value, the magnetron power is reduced while a cooling medium is supplied to the cooling element through the cold source assembly, lowering the temperature of reaction chamber 1, widening the temperature difference between reaction chamber 1 and the whisker material, improving the whisker material's heat dissipation efficiency, and further reducing the whisker material temperature, thus maintaining it within the set range. When all operations are complete and a temperature reduction is needed in reaction chamber 1, the magnetron is shut off while a cooling medium is supplied to the cooling element through the cold source assembly, lowering the temperature of reaction chamber 1. Throughout this process, the main controller controls the rate at which the cold source assembly supplies the cooling medium to the cooling element, thereby controlling the cooling rate of reaction chamber 1.

[0030] In this embodiment, the cooling system includes a liquid cooling component and / or an air cooling component; the cooling element in the liquid cooling component is a liquid cooling pipe 4 disposed in the reaction chamber 1, the cold source component is a cooling circuit, the cooling circuit and the liquid cooling pipe 4 are interconnected, and the cooling circuit is electrically connected to the main controller; the cooling element in the air cooling component is an air inlet 5 and an air outlet 6 disposed on the inner wall of the reaction chamber 1, the cold source component is a fan 7, the fan 7 is disposed at the air inlet 5 and / or the air outlet 6, and the air inlet 5, the air outlet 6 and the fan 7 are all electrically connected to the main controller.

[0031] In this embodiment, the cooling system may include only a liquid cooling component, or only an air cooling component, or both. The liquid cooling component supplies coolant to the liquid cooling pipe 4 via a cooling circuit. The coolant in the liquid cooling pipe 4 exchanges heat with the gas in the reaction chamber 1, reducing the internal temperature of the reaction chamber 1. The main controller controls the rate at which the cooling circuit supplies coolant to the liquid cooling pipe 4, thereby controlling the rate at which the internal temperature of the reaction chamber 1 decreases. The air cooling component controls whether the reaction chamber 1 is connected to the outside environment by controlling the opening and closing of the air inlet 5 and the air outlet 6. When the reaction chamber 1 is connected to the external environment, the fan 7 supplies cooling airflow to the reaction chamber 1 through the air inlet 5, or the fan 7 draws air out of the reaction chamber 1 through the air outlet 6, creating a negative pressure in the reaction chamber 1 and drawing in cooling airflow, thereby reducing the internal temperature of the reaction chamber 1. In this embodiment, the main controller controls the cooling airflow speed by controlling the rotation speed of the fan 7, and controls the inlet and outlet speeds by controlling the opening of the air inlet 5 and the outlet 6. These methods together control the rate at which the internal temperature of the reaction chamber 1 decreases. In this embodiment, the liquid cooling component has a smaller cooling range, while the air cooling component has a faster cooling rate. The liquid cooling component is suitable for situations where the temperature of the whisker material reaches near the set range and the cooling range is small, making it more suitable for precisely controlling the internal temperature of the reaction chamber 1. The air cooling component is suitable for situations where the temperature inside the reaction chamber 1 needs to be reduced rapidly after all operations are completed. The combined control of the two cooling components within the reaction chamber 1 results in better temperature control.

[0032] Preferably, the liquid cooling pipe 4 is coiled around the inner wall of the reaction chamber 1. The cooling circuit includes a cooling tank 8. The inlet and outlet of the liquid cooling pipe 4 and the cooling tank 8 are connected by pipes. A water pump 9 is installed between the outlet of the cooling tank 8 and the liquid cooling pipe 4. The water pump 9 is electrically connected to the main controller. In this embodiment, the coolant is stored in the cooling tank 8. The water pump 9 supplies coolant to the liquid cooling pipe 4. The coolant enters the reaction chamber 1 through the liquid cooling pipe 4. The coolant in the liquid cooling pipe 4 exchanges heat with the air in the reaction chamber 1 through the pipe wall of the liquid cooling pipe 4, reducing the temperature inside the reaction chamber 1. The heated coolant flows back into the cooling tank 8 under water pressure, completing the cooling of the reaction chamber 1. In this embodiment, the power of the water pump 9 is controlled by the main controller, thereby controlling the flow rate of the coolant inside the liquid cooling pipe 4, and thus controlling the cooling effect of the liquid cooling component. In this embodiment, the coolant is water, and the wall material of the liquid cooling pipe 4 is preferably an alloy material, especially a high-temperature alloy, such as a nickel-chromium alloy. The alloy material can isolate microwave transmission and prevent microwaves from heating the coolant.

[0033] In some embodiments, the cooling circuit is a grid pipe, which is connected to the liquid cooling pipe 4, and a water pump is installed between the two. The water pump drives the coolant to flow between the grid pipe and the liquid cooling pipe 4. A fan is installed on one side of the grid pipe, which blows directly onto the grid pipe. The airflow generated by the fan drives the airflow near the grid pipe, thereby dissipating heat and reducing the temperature of the coolant in the grid pipe.

[0034] In a further optimized design, the support frame 2 is rotatably mounted at the bottom of the reaction chamber 1, and is driven by a second motor. The second motor drives the support frame 2 to rotate, which in turn rotates the container 3 containing the whisker material, ensuring that the whisker material at different locations is heated uniformly and preventing localized overheating.

[0035] Preferably, the support frame 2 is detachably connected to several trays 10, all of which are arranged along the extending direction of the support frame 2; the trays 10 are detachably connected to the containers 3. In this embodiment, several trays 10 are detachably connected along the extending direction of the support frame 2, and several containers 3 are detachably connected to each tray 10. When the second motor drives the support frame 2 to rotate, the support frame 2 drives the trays 10 to rotate, which in turn drives the containers 3 to rotate around the rotation axis of the support frame 2, thereby ensuring that the whisker material can be heated uniformly. In this embodiment, the materials of the support frame 2 and the trays 10 can be high-temperature resistant alloys, ceramics, or high-purity silicon carbide, such as nickel-chromium alloys.

[0036] In some embodiments, the reaction chamber 1 is a cylindrical structure, and the support frame 2 is rotatably arranged at the central axis of the cylindrical structure; the tray 10 has a snap-fit ​​hole 11 along its central axis, and the support frame 2 is detachably connected to the tray 10 through the snap-fit ​​hole 11. In this embodiment, compared with the cubic structure reaction chamber 1, the cylindrical structure reaction chamber 1 reduces the number of corners or edges, reduces the generation of strong or weak microwave regions in the reaction chamber 1, and is more conducive to the uniform distribution of microwaves. Moreover, the symmetry of the cylindrical structure makes the reflection and propagation of microwaves in the reaction chamber 1 more uniform, ensuring uniform heating of the whisker material (precursor material); at the same time, the cubic structure has more edges and corners, which makes the reflection and scattering of microwaves more complex. Some microwave energy may be reflected multiple times in the container before being absorbed by the whisker material, affecting the heating efficiency, and may even form weak "cold spots" in some areas. In contrast, the surface of the cylindrical structure is relatively smooth, and the reflection of microwaves on its surface is relatively regular, with fewer complex scattering situations, allowing microwave energy to be absorbed by the whisker material more concentratedly, resulting in higher heating efficiency. In this application, the tray 10 is circular and coincides with the central axis of the reaction chamber 1. That is, the tray 10 and the support frame 2 are arranged concentrically, and the support frame 2 is detachably connected to the tray 10 through the snap-fit ​​hole 11. When the support frame 2 rotates, it drives the tray 10 to rotate synchronously, ensuring that the whisker material is heated evenly.

[0037] In this embodiment, the tray 10 has a protrusion on one side of the snap-fit ​​hole 11, and the support frame 2 has a sliding groove 12 on its radial outer side along its axial direction. The protrusion and the sliding groove 12 are slidably connected, thereby ensuring that the tray 10 can slide along the sliding groove 12 and reach the first designated position. The support frame 2 has a snap-fit ​​groove 17 on its radial outer side along its cross-sectional direction. The snap-fit ​​groove 17 is located at the first designated position, and the sliding groove 12 and the snap-fit ​​groove 17 are connected. The protrusion and the snap-fit ​​groove 17 are slidably connected, thereby ensuring that after the tray 10 slides to the first designated position, it can slide into the snap-fit ​​groove 17. Rotating the tray 10 causes the protrusion to reach the second designated position. The support frame 2 has a fixing groove on its radial outer side at the second designated position, and the fixing groove is connected to the snap-fit ​​groove 17. After the protrusion reaches the second designated position, the tray 10 falls into the fixing groove 18 under the action of gravity, completing the detachable operation of the tray 10 and the support frame 2.

[0038] Preferably, the tray 10 has a plurality of first mounting holes 13, which are arranged along the extending direction of the support frame 2, and the container 3 is snapped into the first mounting holes 13. In this technical solution, the container 3 is usually a crucible, and the shape of the crucible is usually an inverted frustum structure, that is, the diameter of the opening end (upper end) of the crucible is larger than the diameter of the bottom end. When the diameter of the first mounting hole 13 is between the outer diameter of the opening end and the outer diameter of the bottom end of the crucible, it is only necessary to snap the container 3 into the first mounting hole 13. In some embodiments, a mounting sleeve 14 is snapped into the first mounting hole 13, and a second mounting hole is provided in the middle of the mounting sleeve 14, and the container 3 is snapped into the second mounting hole. When the outer diameter of container 3 is all smaller than the inner diameter of the first mounting hole 13, the mounting sleeve 14 is snapped into the first mounting hole 13, and container 3 is snapped into the second mounting hole in the middle of the mounting sleeve 14. Thus, the mounting diameter of the first mounting hole 13 is reduced to the mounting diameter of the second mounting hole. This ensures that even when the outer diameter of container 3 is all smaller than the inner diameter of the first mounting hole 13, container 3 can still be snapped into the tray 10, expanding the applicability of tray 10 for snapping into container 3. That is, it is only necessary to snap into the first mounting hole 13 with mounting sleeves 14 of different specifications to accommodate containers 3 of different diameters.

[0039] In a further optimized design, a microwave stirring blade 15 is rotatably mounted on the top of the reaction chamber 1, driven by a first motor. The microwave stirring blade 15 corresponds to the output end of the waveguide. In this embodiment, the microwave stirring blade 15 is made of metal. During operation, the first motor drives the microwave stirring blade 15 to rotate, reflecting the microwaves transmitted from the waveguide in various directions, thus distributing the microwaves more evenly within the chamber and achieving a better heating effect. Preferably, a metal reflective layer 16 is provided on the inner wall of the reaction chamber 1. The metal reflective layer 16 is made of metal, such as copper or nickel-chromium alloy. The metal reflective layer 16 has good shielding performance, preventing microwave leakage. At the same time, the metal reflective layer 16 can also reflect the internal microwaves, improving microwave utilization. The metal reflective layer 16 and the microwave stirring blade 15 work together to improve microwave reflection efficiency, improve microwave field distribution, and ensure the heating uniformity of the whisker material within the reaction chamber 1. The inner wall of the reaction chamber 1 also includes a high-temperature and corrosion-resistant layer, which can be made of quartz or ceramic fiber. The metal reflective layer 16 is disposed on the side of the high-temperature and corrosion-resistant layer near the reaction chamber 1.

[0040] This invention also includes a microwave leakage detector: the microwave leakage detector is installed inside the reaction chamber 1 to monitor microwave leakage in real time, and is electrically connected to the main controller. Once microwave leakage is detected to exceed the safety threshold, the machine will automatically shut down and issue an alarm to prevent microwave radiation from harming the operators. Emergency stop buttons are provided on the control panel and in key locations so that operators can immediately stop the machine in case of an emergency.
