Description

Technical Field

[0001] This invention relates to the field of hydrogen storage material production technology, and in particular to an integrated machine for producing hydrogen storage materials. Background Technology

[0002] With the development of hydrogen energy, the demand for hydrogen storage materials is increasing day by day. Hydrogen storage materials are materials that can react with hydrogen under certain temperature and pressure conditions to form hydrides and release hydrogen when needed. Magnesium ingots play an important role in the production of hydrogen storage materials due to their good hydrogen storage performance and hydrogen purification effect.

[0003] Currently, magnesium ingots used in hydrogen storage materials are required to reach the nanoscale to improve their surface area and reactivity. Therefore, an integrated machine is needed to process them during production. A common integrated machine consists of a milling device and a refining machine. Milling is a pre-processing step for refining, and its milling effect directly affects the subsequent refining effect. Therefore, a milling device capable of fine milling is required to complete the operation.

[0004] A search revealed that patent document CN218799588U discloses a magnesium ingot chipping device, which includes a housing, legs provided at the four corners of the lower surface of the housing, and a conical hopper for collecting magnesium chips provided at the lower part of the housing.

[0005] The above-mentioned magnesium ingot cutting device has the following shortcomings: When processing magnesium ingots, milling with only two milling cutters cannot guarantee that the resulting magnesium powder particles are of uniform size. Magnesium powder of varying sizes will affect the subsequent refining process, resulting in poor overall product quality. Furthermore, some magnesium powder will adhere to the milling cutters during the milling process, and long-term adhesion will further reduce the milling effect of the cutters. Therefore, it is necessary to design an integrated machine for producing hydrogen storage materials. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an integrated machine for producing hydrogen storage materials, which solves the problems in hydrogen storage material production mentioned in the background section.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A hydrogen storage material production integrated machine includes a main unit, a powder lifting structure, and a refining machine, wherein the powder lifting structure is installed between the main unit and the refining machine, and further includes: The main spindle is rotatably mounted on the host machine, and a positioning plate one is fixedly mounted on the main spindle. A positioning plate two is fixedly mounted on the positioning plate one by a fixing rod. A secondary shaft is rotatably mounted on the main unit. One end of the main shaft, located inside the main unit, rotates within the secondary shaft. A mounting plate is threaded onto the secondary shaft, and multiple clamps are fixedly mounted on the mounting plate. Each clamp holds a magnesium ingot. A differential assembly is installed between the secondary shaft and the main shaft. Two mounting shafts are rotatably mounted on the front end of the main unit, and vertical blade blocks are fixedly mounted on one end of each mounting shaft inside the main unit.

The cleaning section includes two jet hoods fixedly installed in the main unit, and the two jet hoods are respectively positioned opposite the two vertical cutting blocks. An air supply assembly that cooperates with the two jet hoods is installed between the two friction plates.

[0008] Furthermore, the chain drive structure consists of a sprocket one, a chain, and two sprockets two. The sprocket one is fixedly mounted on the main shaft, and the two sprockets two are respectively fixedly mounted on two mounting shafts. The chain is installed between the sprocket one and the two sprockets two. A protective cover that matches the chain drive structure is fixedly mounted on the side wall of the main unit, and a motor is fixedly mounted on the protective cover. The output end of the motor is fixedly connected to the sprocket one.

[0009] Furthermore, the clamp consists of a mounting frame, a chuck, a protrusion, and a positioning block. The mounting frame is fixedly mounted on a mounting plate, the chuck is fixedly mounted on the mounting frame, the protrusion is fixedly mounted on the inner wall of the chuck, the positioning block is slidably mounted on the chuck, and the positioning block corresponds to the position of the protrusion. A screw is threaded onto the chuck, and a compression spring is installed between the screw and the positioning block. A telescopic rod is fixedly mounted on the side wall of the positioning block, and a telescopic groove that mates with the telescopic rod is provided on the side wall of the chuck.

[0010] Furthermore, the differential assembly consists of a fixed gear, a transmission gear, and a fixed gear ring. The fixed gear is fixedly mounted on the main shaft, the fixed gear ring is fixedly mounted on the countershaft, and the transmission gear is rotatably mounted on the main unit via a rotating shaft. Both ends of the transmission gear mesh with the fixed gear and the fixed gear ring, respectively. A fixed cover that cooperates with the fixed gear ring is fixedly mounted on the side wall of the main unit.

[0011] Furthermore, two symmetrically arranged sluice plates are fixedly installed inside the host, and the distance between the bottom of the two sluice plates is less than the sum of the widths of the two friction plates. Both sluice plates are provided with multiple destination discharge holes.

[0012] Furthermore, the transmission assembly consists of a rotating rod, an incomplete gear, a driven bevel gear, a driving bevel gear, and two fixed racks. The rotating rod is rotatably mounted inside the main unit. The incomplete gear is fixedly mounted at the bottom of the rotating rod. The two fixed racks are respectively fixedly mounted on two friction plates, and the two fixed racks respectively engage with the two ends of the incomplete gear. The driven bevel gear is fixedly mounted at the top of the rotating rod, and the driving bevel gear is fixedly mounted on the countershaft, and the driving bevel gear meshes with the driven bevel gear.

[0013] Furthermore, the inner wall of the host has two receiving grooves that slide and seal with the two ends of the friction plate, and springs are installed between the two ends of the friction plate and the two receiving grooves.

[0014] Furthermore, the air supply assembly consists of an air box, a central chamber, two piston plates, two push rods, two connecting pipes, and two one-way air inlet pipes. The air box and the central chamber are both fixedly installed on the side wall of the main unit, and the air box is divided into left and right end air chambers.

The two connecting pipes are respectively fixedly connected between the central chamber and the two jet hoods. The two one-way air inlet pipes are respectively fixedly connected between the central chamber and the two air chambers.

[0015] Furthermore, a protective cover that cooperates with the air box and motor is fixedly installed on the side wall of the main unit, and a one-way return air pipe is installed between the side wall of each of the two air chambers and the main unit.

[0016] Compared with existing technologies, the advantages of this invention are: 1. The design of two vertical cutting blocks and the horizontal distance between their cutting heads allows for more precise milling of magnesium ingots, resulting in smaller magnesium powder particles. This reduces the difficulty of subsequent refining processes and effectively improves the refining effect, ensuring product quality.

[0017] 2: Through the design of the transmission components, the feeding of magnesium ingots by the rotation of the secondary shaft can drive the two friction plates to perform continuous reciprocating reverse motion during the milling process. This motion of the two plates can further crush the magnesium powder with larger particle size, thereby improving the overall milling effect.

[0018] 3: Through the design of the jet hood and air supply components, the continuous reciprocating reverse motion of the two friction plates during the milling process can be used to continuously jet the vertical cutter block, thereby removing the magnesium powder attached to it and ensuring the milling effect on magnesium ingots.

[0019] In summary, this invention, through the rotation of the secondary shaft during the milling process, can simultaneously drive the secondary crushing of magnesium powder, and utilize the secondary crushing action to enable the air jet hood to continuously clean the vertical cutter block. This not only ensures the milling effect of the vertical cutter block but also improves the overall milling uniformity, significantly enhancing the fine milling effect of magnesium ingots.

[0022] Reference Figure 1 A hydrogen storage material production integrated machine includes a main unit 1, a powder lifting structure 3, and a refining machine 37. The powder lifting structure 3 is installed between the main unit 1 and the refining machine 37. The main unit 1 is used to mill magnesium ingots 2 to form 40-mesh magnesium powder. The powder lifting structure 3 is used to lift the milled magnesium powder and send it into the refining machine 37 for further refining to form magnesium powder with a smaller particle size. Both the powder lifting structure 3 and the refining machine 37 are existing products, and their working principles and specific structures will not be described here. The main unit 1 is also equipped with a hatch cover 4 via an electric push rod. When milling the magnesium ingot 2, the electric push rod is used to close the hatch cover 4 to keep the main unit 1 sealed. Then, the argon gas protection device is turned on. When the pressure inside the main unit 1 reaches 0.03MPa, the exhaust valve at the top of the hatch cover 4 is manually opened (to ensure the purity of the argon gas inside the chamber) to perform gas protection. The working pressure is 0.03-0.05MPa. The electric push rod, argon gas protection device and exhaust valve are all existing products, and their working principle and specific structure will not be described here.

[0023] Reference Figure 1 - Figure 15 A hydrogen storage material production integrated machine also includes a main shaft 6, which is rotatably mounted on the main machine 1. A positioning plate 7 is fixedly mounted on the main shaft 6, and a positioning plate 9 is fixedly mounted on the positioning plate 7 via a fixing rod 8. With the cooperation of the positioning plate 7 and the fixing rod 8, the positioning plate 9 can be rotated simultaneously by the rotation of the main shaft 6. The side walls of the positioning plate 7 and the positioning plate 9 are provided with multiple horizontal placement slots for placing one end of the magnesium ingot 2.

[0024] A secondary shaft 10 is rotatably mounted on the main machine 1. One end of the main shaft 6, located inside the main machine 1, rotates within the secondary shaft 10. A mounting plate 11 is threaded onto the secondary shaft 10, and multiple clamps 12 are fixedly mounted on the mounting plate 11. Each clamp 12 holds a magnesium ingot 2. The secondary shaft 10 and the fixed rod 8 are in sliding fit. Through the design of the fixed rod 8, the mounting plate 11 can be driven to rotate simultaneously when the main shaft 6 rotates. This allows multiple magnesium ingots 2 to rotate within the main machine 1 along with the mounting plate 11, continuously changing the magnesium ingots 2 that come into contact with the vertical cutter block 14. When the secondary shaft 10 rotates, the mounting plate 11 can drive the multiple clamps 12 to move along the secondary shaft 10, thereby realizing the feeding of multiple magnesium ingots 2. By adjusting the feeding speed of the magnesium ingots 2, the rotation speed of the mounting plate 11, and the rotation speed of the vertical cutter block 14, synchronous milling of all magnesium ingots 2 can be achieved. The clamp 12 consists of a mounting frame 121, a chuck 122, a protrusion 123, and a positioning block 125. The mounting frame 121 is fixedly mounted on the mounting plate 11, the chuck 122 is fixedly mounted on the mounting frame 121, the protrusion 123 is fixedly mounted on the inner wall of the chuck 122, and the positioning block 125 is slidably mounted on the chuck 122, with the positioning block 125 corresponding to the protrusion 123. A screw 124 is threaded onto the chuck 122, and a compression spring 126 is installed between the screw 124 and the positioning block 125. A fixed spring 126 is installed on the side wall of the positioning block 125. The mounting bracket 122 is equipped with a telescopic rod, and the side wall of the clamp 122 is provided with a telescopic groove that cooperates with the telescopic rod. When fixing the magnesium ingot 2, it is placed on the positioning plate 29 and pushed into the corresponding clamp 122 until one end contacts the mounting bracket 121. Then, by turning the screw 124 on the adjacent clamp 122, the positioning block 125 moves closer to the protrusion 123, thus completing the effective fixing of the magnesium ingot 2. Through the design of the compression spring 126, it can be ensured that the positioning block 125 always applies an effective clamping force to the magnesium ingot 2, thereby improving the fixing effect of the magnesium ingot 2.

[0025] A differential assembly is installed between the secondary shaft 10 and the main shaft 6. The differential assembly consists of a fixed gear 33, a transmission gear 34, and a fixed gear ring 35. The fixed gear 33 is fixedly installed on the main shaft 6, and the fixed gear ring 35 is fixedly installed on the secondary shaft 10. The transmission gear 34 is rotatably installed on the main machine 1 via a rotating shaft, and both ends of the transmission gear 34 mesh with the fixed gear 33 and the fixed gear ring 35, respectively. A fixed cover 36 that cooperates with the fixed gear ring 35 is fixedly installed on the side wall of the main machine 1. The rotating shaft is not shown in the figure. The rotating shaft is rotatably installed on the side wall of the main machine 1 and is fixedly connected to the transmission gear 34. Under the action of the transmission gear 34, the rotation of the main shaft 6 can be transmitted to the fixed gear ring 35 via the fixed gear 33, so that the secondary shaft 10 can rotate at the same time. By designing the dimensions of the transmission gear 34, the fixed gear 33, and the fixed gear ring 35, the transmission ratio between the main shaft 6 and the secondary shaft 10 can be controlled, thereby regulating the feeding speed of the magnesium ingot 2.

[0026] Two mounting shafts 13 are rotatably mounted on the front end of the main unit 1. Vertical cutter blocks 14 are fixedly mounted on one end of each mounting shaft 13 within the main unit 1. The rotation of the vertical cutter blocks 14 enables milling of the corresponding magnesium ingot 2. In specific operation, the runout of the cutter tips of the two vertical cutter blocks 14 is adjusted to be less than or equal to 0.02 mm, and the horizontal distance between their cutter tips is set to 0.05 mm. This horizontal distance allows for further fine milling of the magnesium ingot 2. A chain drive structure 15 is installed between the end of the main spindle 6 furthest from the differential assembly and the two mounting shafts 13. The chain drive structure 15 consists of a sprocket, a chain, and two sprockets. The main unit consists of a sprocket 1 fixedly mounted on the main shaft 6, two sprockets 2 fixedly mounted on two mounting shafts 13 respectively, and a chain installed between the sprocket 1 and the two sprockets 2. A protective cover 16 that cooperates with the chain drive structure 15 is fixedly mounted on the side wall of the main unit 1, and a motor 5 is fixedly mounted on the protective cover 16. The output end of the motor 5 is fixedly connected to the sprocket 1. When the motor 5 is working, it can drive the main shaft 6 and the two mounting shafts 13 to rotate simultaneously through the chain drive structure 15. By controlling the size of the sprocket 1 and the sprocket 2, the transmission ratio between the main shaft 6 and the mounting shafts 13 can be adjusted, thereby controlling the speed of the mounting plate 11 and the speed of the vertical cutter block 14.

[0027] The main unit 1 has two symmetrically arranged sluice plates 17 fixedly installed inside. Each of the two sluice plates 17 has multiple 40-mesh discharge holes. The bottom wall of the main unit 1 is an inverted trapezoid, and the bottom of the main unit 1 has a discharge trough that cooperates with the powder lifting structure 3. Through the design of the two sluice plates 17, magnesium powder with the required particle size can be separated from magnesium powder with a larger particle size, while magnesium powder with a larger particle size slides along the inclined surface of the sluice plate 17 towards the middle of the two sluice plates 17. The abrasive section is used to perform secondary crushing of large-diameter magnesium powder after milling. The abrasive section includes two friction plates 18 that are slidably mounted on the main unit 1. The friction plates 18 are plates with multiple friction teeth. The sides of the two friction plates 18 with friction teeth are close to each other. The distance between the bottoms of the two sluice plates 17 is less than the sum of the widths of the two friction plates 18. The magnesium powder of the particle size pad falls from between the two sluice plates 17 and enters the space between the two friction plates 18 for secondary crushing.

[0028] A transmission assembly is installed between the secondary shaft 10 and the two friction plates 18. The transmission assembly consists of a rotating rod 21, an incomplete gear 22, a driven bevel gear 23, a driving bevel gear 24, and two fixed racks 20. The rotating rod 21 is rotatably installed inside the main unit 1. The incomplete gear 22 is fixedly installed at the bottom of the rotating rod 21. The two fixed racks 20 are respectively fixedly installed on the two friction plates 18, and the two fixed racks 20 are respectively engaged with the two ends of the incomplete gear 22. The driven bevel gear 23 is fixedly installed at the top of the rotating rod 21. The driving bevel gear 24 is fixedly installed on the secondary shaft 10, and the driving bevel gear 24 meshes with the driven bevel gear 23. When the secondary shaft 10 rotates, the rotating rod 21 can be driven to rotate through the meshing of the driving bevel gear 24 and the driven bevel gear 23. Then, through the meshing effect of the incomplete gear 22 and the two fixed racks 20, the two friction plates 18 move in opposite directions. The friction teeth between them are used to perform secondary crushing on the falling large-diameter magnesium powder to achieve the specified mesh size requirement. Two receiving grooves are provided on the inner wall of the main unit 1, which slide and seal with the two ends of the friction plate 18. Springs 19 are installed between the two ends of the friction plate 18 and the two receiving grooves. The incomplete gear 22 has two symmetrically arranged toothed parts and two symmetrically arranged missing tooth parts. The arc length of the toothed parts is equal to the length of the fixed rack 20. At the same time, the arc length of the missing tooth part on the incomplete gear 22 is greater than the length of the fixed rack 20. By utilizing the design of the missing tooth part on the incomplete gear 22 and the elastic force of the spring 19, the friction plate 18 can be reset under the action of the spring 19 when it moves to the maximum distance. After resetting, it will mesh with the toothed part on the incomplete gear 22 again, thereby realizing the continuous reciprocating motion of the friction plate 18. This ensures that the two friction plates 18 can always maintain opposite motion during the milling process, ensuring the crushing effect of large-diameter magnesium powder.

[0029] The cleaning section is used to clean the two vertical cutter blocks 14 during the milling process. The cleaning section includes two jet hoods 29 fixedly installed in the main unit 1, and the two jet hoods 29 are respectively positioned opposite the two vertical cutter blocks 14. The two jet hoods 29 are respectively located at the upper end of the two vertical cutter blocks 14. An air supply assembly that cooperates with the two jet hoods 29 is installed between the two friction plates 18. The air supply assembly consists of an air box 25, a concentration chamber 28, two piston plates 26, two push rods 27, two connecting pipes 30, and two one-way air inlet pipes 31. Both the air chamber 25 and the concentration chamber 28 are fixedly installed on the side wall of the main unit 1. The air chamber 25 is divided into left and right air chambers, which are not connected. Two connecting pipes 30 are fixedly connected between the concentration chamber 28 and the two jet hoods 29, respectively. Two one-way air inlet pipes 31 are fixedly connected between the concentration chamber 28 and the two air chambers, respectively. The one-way air inlet pipes 31 are connected to the end of the air chamber away from the main unit 1. The one-way air inlet pipes 31 can unidirectionally input the gas in the air chamber into the concentration chamber 28. The connecting pipes 30 can divide the gas entering the air chamber into two parts and input them into the two air chambers respectively. Argon gas is ejected from the jet hood 29. To ensure the gas protection effect inside the main unit 1, both the gas chamber and the concentration chamber 28 are filled with argon gas. One-way return gas pipes are installed between the side walls of the two gas chambers and the main unit 1. The one-way return gas pipes are connected to the end of the gas chamber away from the main unit 1. The one-way return gas pipes are not shown in the figure. The one-way return gas pipes allow the argon gas inside the main unit 1 to enter the gas chamber in one direction for replenishment. Thus, the reciprocating flow and pressurization of argon gas are used to clean the vertical cutting block 14, blowing off the magnesium powder adhering to it, and ensuring the milling effect of the vertical cutting block 14. Two piston plates 26 are respectively sealed and slidably installed in two air chambers. Two push rods 27 are respectively fixedly installed between the two piston plates 26 and the two friction plates 18. With the design of the two push rods 27, the two piston plates 26 can be moved by the movement of the two friction plates 18, thereby providing a drive for the flow of gas. Since the two friction plates 18 always maintain opposite movements, one of the two air chambers will always input compressed air into the concentration chamber 28 through the one-way return air pipe. Then, under the diversion effect of the two concentration chambers 28 and the two connecting pipes 30, the two jet hoods 29 can always spray air outward, ensuring that the vertical cutting block 14 can be effectively cleaned during the milling process. A protective cover 32 that cooperates with the air box 25 and the motor 5 is fixedly installed on the side wall of the main unit 1.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
