[0035] A temperature sensor 3 and a semiconductor heat sink are also provided. The temperature sensor 3 is fixed on the reaction tank 1 and is used to monitor the temperature of the reaction tank 1 in real time. The reaction tank 1 is an electrically heated reaction tank 1. The semiconductor heat sink is provided on the reaction tank 1 for heat dissipation. The controller transmits data with the temperature sensor 3, and the controller controls the semiconductor heat sink.

[0036] Among them, the semiconductor heat sink adopts the existing product of the existing technology and will not be described in detail. The temperature sensor adopts the existing product, and its brand and model can be selected according to needs.

[0037] In this embodiment, the reaction tank 1 is heated by its own electric heating function, and the temperature sensor 3 performs temperature monitoring. In order to solve the problem of different temperatures during the two-stage decomposition of fine seeds, the temperature of the fine seeds is higher during the first stage of decomposition. When the second stage of decomposition is required, the controller can control the semiconductor heat sink to accelerate the heat dissipation of the reaction tank 1 until the required temperature is reached.

[0038] It also includes an exchange tube anti-clogging component 5, which includes a support ring 502, a first L-shaped connecting rod 503, a second L-shaped connecting rod 504, a movable ring 505 and a top rod 506. One side of the support ring 502 is fixedly connected to the first L-shaped connecting rod 503, the vertical rod of the first L-shaped connecting rod 503 passes through the bracket 2, the cross rod end of the first L-shaped connecting rod 503 is fixedly connected to the second L-shaped connecting rod 504, and the lower end of the vertical rod of the second L-shaped connecting rod 504 is fixedly connected to the movable ring 505.

The top rod 506 can be inserted into the exchange tube 203, and the top rod 506 and the exchange tube 203 are arranged in a one-to-one correspondence.

[0039] In this embodiment, the ejector rod 506 of the exchange tube anti-clogging assembly 5 can be reciprocally inserted into the exchange tube 203 to eject the fine seeds in the exchange tube 203 to prevent clogging.

[0040] The exchange tube anti-clogging component 5 is connected to the fine seed circulation component 4 through a linkage component 6. The linkage component 6 is used to drive the push rod 506 to move up and down, continuously inserting and pulling out the exchange tube 203, and ejecting the fine seeds blocked in the exchange tube 203.

[0041] The linkage assembly 6 includes a second bevel gear 601, a guide shaft 602, a straight groove rod 603, an eccentric wheel 604 and a third L-shaped connecting rod 605. The bevel gear ring 403 engages the second bevel gear 601. The central axis of the second bevel gear 601 is rotatably connected to the bracket 2. The end of the central axis of the second bevel gear 601 is fixedly connected to the center of the eccentric wheel 604. The eccentric shaft of the eccentric wheel 604 is arranged in the slide groove of the straight groove rod 603. The eccentric shaft of the eccentric wheel 604 matches the slide groove of the straight groove rod 603. The upper center of the straight groove rod 603 is fixed to the support ring 502 through the third L-shaped connecting rod 605. The lower center of the straight groove rod 603 is fixedly connected to the guide shaft 602. The guide shaft 602 passes through the bracket 2.

[0042] In this embodiment, the rotation of the bevel gear ring 403 can drive the second bevel gear 601 to rotate, and the second bevel gear 601 drives the eccentric wheel 604 to rotate. The eccentric shaft of the eccentric wheel 604 rotates circumferentially in the sliding groove of the straight groove rod 603, thereby driving the straight groove rod 603 to move up and down. The straight groove rod 603 drives the guide shaft 602 to move up and down along the circular hole passing through the bracket 2. The straight groove rod 603 drives the third L-shaped connecting rod 605, the support ring 502 and the first L-shaped connecting rod 503 to move up and down. The first L-shaped connecting rod 503 finally drives the movable ring 505 and the top rod 506 to move up and down.

[0043] The support ring 502 is rotatably connected to a circular wheel 9, the central axis of the circular wheel 9 is fixedly connected to the upper end of the power rod 404, and the axis of the movable ring 505 and the circular wheel 9 are the same.

[0044] Furthermore, there is a certain gap between the circulation driving block 4041 and the umbrella-shaped cavity 202 for the upward and downward movement of the circulation driving block 4041 . The diameter of the power rod 404 is smaller than the diameter of the transmission channel 201 , so as to facilitate the entry and circulation of fine seed crystals.

[0045] In order to achieve more complete contact between the fine seeds and the air and the electrolyte, and to quickly decompose the alumina, a circular wheel 9 is set in the support ring 502. The support ring 502 drives the circular wheel 9 to move up and down during the up and down movement. The circular wheel 9 drives the power rod 404 and the guide rod 405 to move up and down. The power rod 404 drives the circulation drive block 4041 to move up and down. In the process of the power rod 404 moving up and down, since the guide rod 405 is fixed, the guide rod 405 passes through the turntable 406, and the turntable 406 follows the bevel gear ring 403 to rotate, which can realize the rotation of the guide rod 405 and the power rod 404, drive the circular wheel 9 and the circulation drive block 4041 to rotate, and realize the circulation drive block 4041 to rotate and move up and down in the umbrella-shaped cavity 202. In the process of the circulation drive block 4041 moving up and down, air and fine seeds are continuously inhaled from the receiving funnel 806 and discharged from the exchange tube 203. The electrolyte and fine seeds enter and exit the circulation hole 204 and are discharged from the exchange tube 203 to realize self-circulation.

[0046] Specifically, when the circulating drive block 4041 rotates and moves up and down within the umbrella-shaped cavity 202, its unique structure and movement play a key role. The circulating drive block 4041 is conical in shape, and the upper curved surface is fixed with spirally arranged curved fan blades 4042. During high-speed rotation, the air within the umbrella-shaped cavity 202 is rapidly stirred and driven toward the exchange tube 203. Because there is a certain pressure difference between the exchange tube 203 and the external environment, and the exchange tube 203 serves as a channel for air exhaust, when a large amount of air is continuously driven toward the exchange tube 203, the air pressure within the umbrella-shaped cavity 202 will rapidly decrease, thereby forming a negative pressure state within the umbrella-shaped cavity 202 relative to the external environment.

[0047] Under the combined effects of gravity, the centrifugal force generated by the rotation of the circulating drive block 4041, and the airflow force, the fine seeds are sucked into the umbrella-shaped cavity 202 from the receiving funnel 806. The receiving funnel 806 serves as the feed port for the fine seeds. Under the attraction of the negative pressure in the umbrella-shaped cavity 202, the fine seeds in the storage trough 801 can more smoothly enter the transmission pipeline 201 through the feed channel 805 and the feed pipe 804, and finally reach the umbrella-shaped cavity 202.

[0048] Under the action of negative pressure, air is continuously drawn into the umbrella-shaped cavity 202 from the outside, where it mixes thoroughly with the incoming fine seeds. Subsequently, driven by the continuous rotation and up-and-down movement of the circulation drive block 4041, the fine seeds mixed with air enter the umbrella-shaped cavity 202 through the circulation hole 204. At this point, due to the kinetic energy imparted by the power rod 404 driving the circulation drive block 4041 to rotate, as well as the pressure difference between the inside and outside of the umbrella-shaped cavity 202, the fine seed and air mixture is discharged into the reaction tank 1 through the exchange tube 203. The discharged mixture continues to react in the reaction tank 1, while some of the unreacted fine seeds and the newly inhaled air re-enter the umbrella-shaped cavity 202 under the above mechanism. This reciprocating process achieves continuous circulation of fine seeds and air within the device, ensuring an adequate oxygen supply during the reaction process and promoting the decomposition of aluminum oxide. Simultaneously, the electrolyte also enters and exits the umbrella-shaped cavity 202 through the circulation hole 204 at the bottom of the transmission pipe 201, fully contacting the fine seeds, further optimizing the reaction environment and improving decomposition efficiency.

[0049] The use of the present invention is as follows:

[0050] Turn on the motor 401. After the motor 401 is running, its output shaft drives the first bevel gear 402 to rotate. Since the first bevel gear 402 and the bevel gear ring 403 are meshed with each other, the bevel gear ring 403 rotates accordingly, thereby driving the turntable 406 to rotate. The turntable 406 drives the power rod 404 to rotate. Finally, the power rod 404 drives the circulation drive block 4041 to rotate in the umbrella-shaped cavity 202, realizing the initial circulation of the fine seeds in the umbrella-shaped cavity 202, laying the foundation for the mixing of subsequent reaction materials. At the same time, according to the temperature requirements of the initial stage of the two-stage decomposition process of alumina, the electric heating function of the reaction tank 1 is turned on. The reaction system is heated by the electric heating module of the reaction tank 1. The temperature sensor 3 accurately monitors the temperature in the reaction tank 1 in real time to ensure that the temperature reaches the starting temperature range set by the process. The steering gear 802 is started, and the steering gear 802 drives the spiral transmission rod 803 to rotate. The fine seeds in the storage tank 801 are pushed by the spiral transmission rod 803 and move along the feeding channel 805 toward the receiving funnel 806. After passing through the receiving funnel 806 and the feeding pipe 804, they are smoothly transported to the transmission pipeline 201 and finally enter the reaction system, where they mix with the circulating materials and start the seed decomposition reaction.

[0051] During the entire reaction operation, the operator should continue to pay attention to the data fed back by the temperature sensor 3 and check the temperature changes in real time through the display screen or control system interface;

[0052] When the two-stage decomposition process of aluminum oxide enters the second stage and the reaction temperature needs to be lowered, the controller issues a command to start the semiconductor heat sink. The semiconductor heat sink quickly dissipates heat from the reaction tank 1 according to the heat dissipation power and target temperature set by the controller until the temperature in the reaction tank 1 reaches the temperature range required by the second stage decomposition process, ensuring that the reaction continues to proceed efficiently under appropriate temperature conditions.

[0053] As the equipment continues to operate, the fine seeds may be blocked in the exchange tube 203 during the circulation and reaction process. At this time, due to the rotation of the bevel gear ring 403, the second bevel gear 601 meshing with it also rotates, and the second bevel gear 601 drives the eccentric wheel 604 to rotate. The eccentric shaft of the eccentric wheel 604 performs a circular motion in the slide groove of the straight groove rod 603, thereby driving the straight groove rod 603 to move up and down. The straight groove rod 603 drives the support ring 502 to move up and down through the third L-shaped connecting rod, and the support ring 502 drives the moving ring 505 to move up and down, and finally, the push rod 506 is driven by the linkage assembly 6 to reciprocate and insert into the exchange tube 203, thereby timely ejecting the fine seeds that may be blocked in the exchange tube 203, ensuring that the exchange tube 203 is unobstructed and maintaining stable operation of the equipment.

Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
