Aluminum trihydride has a high hydrogen storage capacity, with a theoretical hydrogen mass fraction of up to 10.1%, and has great application potential in the field of energy storage. However, its original powder state or irregular block shape has some problems in practical hydrogen storage applications, such as poor fluidity and uneven packing density in hydrogen storage containers.

[0003] A granulator with a particle size control structure consists of multiple systems. The material is fed, mixed, and granulated in sequence.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 This utility model provides an embodiment of a granulator with a particle size control structure for the preparation of aluminum trihydride. The granulator includes a support plate 3, which serves as the basic support component of the entire device, providing a stable mounting platform for numerous internal components such as a motor 4. The motor 4 is fixedly connected inside the support plate 3, providing rotational power to a rotating rod 5, driving it to rotate, thereby driving a series of transmission components, including a connecting rod 6. The rotating rod 5 is fixedly connected to the drive end of the motor 4, rotating under the drive of the motor 4 and transmitting the motor's circumferential motion to the connecting rod 6. The top of the rotating rod 5 is rotatably connected to the connecting rod 6, which connects the rotating rod 5 to a triangular connecting block 7, serving as a force transmission and motion conversion mechanism. The bottom of the connecting rod 6 is rotatably connected to the triangular connecting block 7, which has a fixed post 8 fixed inside, providing stable support and positioning, and is also rotatably connected to a connecting rod 9. The triangular connecting block 7 is internally fixedly connected to a fixed post 8, the bottom of which is fixed inside the support plate 3, providing vertical support and positioning for the triangular connecting block 7. The triangular connecting block 7 is internally rotatably connected to a connecting rod 9, which connects the triangular connecting block 7 to the sliding plate 10, transmitting the movement of the triangular connecting block 7 to the sliding plate 10. The rod 9's rotation allows for adjustment of the direction and magnitude of the force.

[0033] A sliding plate 10 is rotatably connected to the left side of the connecting rod 9. A square sliding block 28 at the bottom of the sliding plate 10 is slidably connected to the inside of the support plate 3, ensuring stable horizontal sliding of the sliding plate 10. A square sliding block 28 is fixedly connected to the bottom of the sliding plate 10, cooperating with a slide rail or groove inside the support plate 3 to provide precise horizontal sliding guidance for the sliding plate 10. A connecting pipe 11 is slidably connected to the top of the sliding plate 10, with the top of the connecting pipe 11 connected to a material container 16, serving as the channel for material to flow from the material container 16 to the granulation area. A fixing ring 12 is fixedly connected to the outside of the connecting pipe 11, ensuring that the connecting pipe 11 can be dynamically adjusted as needed during material transmission, guaranteeing the stability and uniformity of material feeding. A triangular connecting block 15 is fixedly connected to the left side of the fixing ring 12, connecting the fixing ring 12 and the rotating block 13, transmitting motion and force between the connecting pipe 11 and the rotating block 13. A rotating block 13 is fixedly connected to the left side of the triangular connecting block 15. The bottom of the rotating block 13 is connected to the vibration assembly, the right side is fixedly connected to the triangular fixing block 14, and the left side is fixedly connected to the triangular connecting block 15. It is a key component connecting the relevant parts of the material container 16 and the vibration assembly. A vibration assembly for accelerating material feeding is rotatably connected to the bottom of the rotating block 13.

[0034] Reference Figure 2 , Figure 4 The vibration assembly includes a support frame 1, the top of which is rotatably connected to the bottom of the rotating block 13. It transmits the vibration generated by the vibration assembly to the container 16 and connecting pipe 11, acting as a bridge for force integration and transmission in the entire structure. A second support plate 18 is fixedly connected to the top right side of the support frame 1, providing a mounting platform for the second motor 19 and ensuring its stability during operation. The second motor 19 is fixedly connected inside the second support plate 18, serving as the power source for the vibration assembly and driving the rotating disk 20 to rotate. The rotating disk 20 is fixedly connected to the drive end of the second motor 19, causing the rotating rod 21 at its top to rotate in a circular motion. The rotating rod 21 is fixedly connected to the top of the rotating disk 20, connecting it to the moving rod 22. It transmits the circular motion of the rotating disk 20 to the moving rod 22, and changes the direction and magnitude of the force through its own rotation during the transmission process.

[0035] A movable rod 22 is rotatably connected to the top of the rotating rod 21. A fixed rod 23 is rotatably connected to the left side of the movable rod 22. The fixed rod 23 is rotatably connected to the movable rod 22, providing a fixed fulcrum for the movable rod 22 and restricting its horizontal displacement, allowing it to swing only around the fixed rod 23 at a specific angle. This restriction helps convert the motion transmitted from the rotating rod 21 into a stable and predictable oscillating motion, ensuring the stable and reliable vibration effect of the vibration assembly. A fixed plate 24 is rotatably connected inside the movable rod 22. The fixed plate 24 ensures that the movable rod 22 can drive the sliding rod 25 to move smoothly back and forth during the oscillation, so that the vibration can be effectively transmitted to the baffle 26 and the container 2, producing a continuous and stable vibration effect on the material. A sliding rod 25 is rotatably connected to the rear side of the fixed plate 24. The sliding fit between the sliding rod 25 and the fixed plate 24 needs to ensure low friction and high precision to reduce energy loss and ensure the accuracy and efficiency of vibration transmission. A baffle 26 is fixedly connected to the rear side of the sliding rod 25. The vibration of the baffle 26 directly acts on the material in the container 2. Through continuous impact and vibration, the material overcomes friction and cohesion, accelerates the feeding process, and at the same time helps the material to loosen and mix in the container 2, improving the uniformity and quality of granulation.

[0036] Reference Figures 2 to 4The bottom of the fixed column 8 is fixedly connected to the inside of the support plate 3, and the outside of the square sliding block 28 is slidably connected to the inside of the support plate 3. The square sliding block 28 ensures the stability and accuracy of the slide rail. The top of the connecting pipe 11 is fixedly connected to the material container 16, which is used to store the material to be granulated. The top connecting cover prevents impurities from entering and ensures the purity of the material. The top of the material container 16 is rotatably connected to the connecting cover, and the outside of the material container 16 is fixedly connected to the fixing ring 17. The fixing ring 17 shares the force on the material container 16 during movement, preventing the material container 16 from loosening or displacing due to vibration or other external forces, and ensuring the safe and reliable storage and feeding process of the material in the material container 16. The left side of the fixing ring 17 is fixedly connected to the triangular fixing block 14, which is fixed between the fixing ring 17 and the rotating block 13 of the material container 16, and plays a role in strengthening the connection and fixation. Its triangular structure provides excellent stability, effectively resisting forces from different directions and ensuring that the container 16 remains relatively stationary in complex motion environments. This ensures stable material feeding and also helps maintain the integrity of the entire device structure. The left side of the triangular fixing block 14 is fixedly connected to the right side of the rotating block 13. The top of the support plate 18 is fixedly connected to the fixing plate 24, which provides an installation platform for the motor 19, ensuring its stability during operation. A sliding rod 25 is slidably connected inside the fixing plate 24. The container 2 is fixedly connected to the top of the support frame 1. The rear side of the baffle 26 contacts the front side of the container 2, and vibrates back and forth under the action of the sliding rod 25. A connecting cover is fixedly connected to the bottom of the support plate 3. The top of the container 2 contacts the bottom of the connecting cover. A stirring rod 27 is rotatably connected to the bottom of the connecting cover, and the bottom of the stirring rod 27 is rotatably connected below the connecting cover, located inside the container 2. During the granulation process, the stirring rod 27 can stir and agitate the materials, making the mixture more uniform and preventing clumping or stratification. Its stirring speed, direction, and shape can be adjusted according to the material characteristics and granulation process requirements to optimize the material processing effect and improve the consistency and stability of granulation.

[0037] Working principle: During operation, the support plate 3 supports internal components such as the motor 4. The motor 4 drives the rotating rod 5 to rotate and transmits force to the connecting rod 6. The connecting rod 6 is connected to the triangular connecting block 7. The internal fixed column 8 provides support and positioning and is rotatably connected to the connecting rod 9. The connecting rod 9 is connected to the sliding plate 10. The square sliding block 28 at the bottom of the sliding plate 10 slides and guides along the support plate 3. The top of the sliding plate 10 is slidably connected to the connecting pipe 11. The top of the connecting pipe 11 is connected to the material container 16 and has a fixing ring 12 on the outside. The fixing ring 12 is connected to the rotating block 13 via the triangular connecting block 15. The rotating block 13 is connected to the material container 16 and plays a key role in transmission. The material flows to the granulation area under the action of the connecting pipe 11 and the container 2. The cooperation of each component and other structures can control the granulation particle size. Quantitative feeding can ensure that the amount of aluminum trihydride raw material participating in each granulation is relatively fixed. During the granulation process, the amount of raw materials directly affects the size and shape of the particles. By changing the quantitative feeding speed and observing the changes in particle size, the optimal feeding speed and target particle size can be determined. This is very helpful for improving the process level and product performance. Quantitative feeding can make the reaction proceed in a relatively stable state, reduce the possibility of accidents, and ensure production safety.

[0038] The top of the support frame 1 is connected to the rotating block 13 to transmit vibration. The support plate 2 18 on the right top is equipped with the motor 2 19. The motor 2 19 drives the rotating disk 20 to rotate, and the rotating rod 21 on its top moves in a circular motion and is connected to the moving rod 22 to change the direction of force. The left side of the moving rod 22 is rotatably connected to the fixed rod 2 23 to form a fulcrum, which restricts its horizontal displacement. The inside is rotatably connected to the fixed plate 24 to ensure that the sliding rod 25 moves back and forth smoothly. The sliding rod 25 and the fixed plate 24 are in low-friction and high-precision cooperation. The rear fixed baffle 26 vibrates and acts on the material in the container 2, accelerating the feeding and promoting loose mixing, improving the uniformity and quality of granulation. In the mixing granulator, the material may sometimes be blocked in some parts of the equipment due to moisture, high viscosity or other reasons, such as the discharge port and around the mixing blades. For some fine powders produced in the preparation of aluminum trihydrogen, vibration can promote them to agglomerate into particles of appropriate size. When the mixing granulator is vibrated, the aluminum trihydrogen raw materials and binders inside can be more fully mixed under the action of vibration.
