Description

Technical Field

[0001] This invention relates to the field of solid-state hydrogen storage technology, specifically to a solid-state hydrogen storage device. Background Technology

[0002] Hydrogen energy is a green energy source with advantages such as wide availability, high energy density, large-scale storage capability, and clean, low-carbon operation, making it considered the most ideal "ultimate energy source" for humankind. Among these technologies, solid-state hydrogen storage (SSD) using hydrides has shown remarkable performance in recent years, offering advantages such as high volumetric hydrogen storage density, low pressure, and safe storage and transportation. However, it places high demands on storage materials, making it more suitable for stationary hydrogen storage. With significant improvements in the performance of storage materials, SSDs have demonstrated excellent application prospects and potential in high-safety hydrogen refueling (storage) stations.

[0003] However, in current hydrogen storage, the magnesium-based hydrogen storage material powder is placed directly in the storage tank, allowing the hydrogen to react with the magnesium-based hydrogen storage material on its own. However, due to the stacking of the magnesium-based hydrogen storage material, the hydrogen cannot fully react with the magnesium-based hydrogen storage material, resulting in a low hydrogen storage capacity.

[0011] Preferably, a bidirectional lead screw located directly above the isolation cover is rotatably connected to the top of the tank body.

[0014] The beneficial effects of this invention are reflected in:

[0015] 1.

[0017] 3. This solid hydrogen storage device, by setting up an isolation cover, a pressing motor drives a bidirectional lead screw to rotate, which in turn moves a moving block, causing the support rod to push the isolation cover down to seal the groove. At the same time, the sealing sleeve moves down to expose the movable groove. Simultaneously, the connecting plate and connecting column pull the sealing plate down to seal it against the sealing ring. The heating plate heats the magnesium-based hydrogen storage material, causing the hydrogen stored in the magnesium-based hydrogen storage material to overflow.

A fixed plate 4 is fixedly installed inside the tank 1 below the partition 5. A rotating shaft 12 located directly below the inlet pipe 2 is rotatably connected through the middle of the partition 5. A drive blade 14 located above the partition 5 is fixedly installed at the top of the rotating shaft 12. A jet pipe 17 with its end facing the drive blade 14 is fixedly installed at the bottom of the outer periphery of the inlet pipe 2. A stirring blade 13 located above the fixed plate 4 is fixedly installed on the outer periphery of the rotating shaft 12. A connecting pipe 6 is fixedly installed inside the side wall of the tank 1. A gas guide pipe 7 located above the partition 5 is integrally connected to the top of the connecting pipe 6. A dispersion pipe 8 penetrating into the interior of the fixed plate 4 is integrally connected to one side of the connecting pipe 6. An outlet is provided at the bottom of the dispersion pipe 8. Through the inlet pipe 2 and connecting pipe 6, hydrogen enters the tank 1 from above the internal partition 5 via the inlet pipe 2, then enters the connecting pipe 6 and the dispersion pipe 8 via the guide pipe 7, and is sprayed out through the outlet 9 onto the powdered magnesium-based hydrogen storage material above the fixed plate. Several outlets 9 evenly distributed below the fixed plate 4 spray the hydrogen delivered by the inlet pipe 2 onto the powdered magnesium-based hydrogen storage material, allowing the hydrogen to react fully with the magnesium-based hydrogen storage material, thereby increasing the hydrogen storage capacity of the device. Through the jet nozzle and drive blade 14, hydrogen is sprayed out through the jet pipe 17 onto the drive blade 14, causing the drive blade 14 to rotate, which in turn drives the rotating shaft 12 to rotate, thereby driving the stirring blade 13 to rotate, stirring the powdered magnesium-based hydrogen storage material above the fixed plate 4, thus allowing the hydrogen to react fully with the magnesium-based hydrogen storage material, further increasing the hydrogen storage capacity and improving the practical value of the device.

[0032] In one embodiment of the present invention, a fixed circular plate 10 located below the dispersion tube 8 is fixedly installed on the bottom of the fixed plate 4, and the air outlet 9 is disposed through the fixed circular plate 10. The bottom of the air outlet 9 is flush with the bottom of the fixed circular plate 10. A heating plate 11 is fixedly installed on the top of the fixed plate 4, and the top of the heating plate 11 is flush with the top of the fixed plate 4.

[0033] In one embodiment of the present invention, a set of dispersion tubes 8 are provided through the bottom of the partition 5, and a fixed circular plate 10 located below the dispersion tubes 8 is fixedly installed at the bottom of the partition 5, and a heating plate 11 is fixedly installed at the bottom inside the tank 1.

[0034] In one embodiment of the present invention, the middle part of the air intake pipe 2 is provided with a movable groove 16 located above the jet pipe 17. A sealing ring 22 located above the movable groove 16 is integrally provided inside the air intake pipe 2. The movable groove 16 is located inside the tank body 1. A connecting plate 18 is slidably connected inside the movable groove 16. A connecting post 19 that penetrates the sealing ring 22 is fixedly installed on the top of the connecting plate 18. A sealing sheet 20 is integrally connected to the top of the connecting post 19.

[0035] In one embodiment of the present invention, the diameter of the inner annular surface of the sealing ring 22 is larger than the diameter of the connecting column 19, and the diameter of the sealing sheet 20 is larger than the diameter of the inner annular surface of the sealing ring 22. A rubber sealing ring is provided on the contact surface between the sealing sheet 20 and the sealing ring 22. By setting the isolation cover 21, the pressing motor 24 drives the bidirectional lead screw 23 to rotate, which drives the moving block 25 to move, so that the support rod 26 pushes the isolation cover 21 down to seal the sealing groove 15. At the same time, the sealing sleeve 27 moves down to expose the movable groove 16. At the same time, the sealing sheet 20 is pulled down by the connecting plate 18 and the connecting column 19 to seal the sealing sheet 20 against the sealing ring 22. The heating plate 11 heats the magnesium-based hydrogen storage material, causing the hydrogen stored in the magnesium-based hydrogen storage material to overflow. The overflowed hydrogen enters the interior of the isolation cover 21 through the movable groove 16 and the jet pipe 17, and is then discharged through the gas outlet pipe 3.

[0036] In one embodiment of the present invention, a sealing sleeve 27 located outside the air intake pipe 2 is connected to the outer peripheral surface of the connecting plate 18. The sealing sleeve 27 is slidably connected to the outer peripheral surface of the air intake pipe 2. An isolation cover 21 is integrally connected to the bottom of the outer peripheral surface of the sealing sleeve 27. The diameter of the isolation cover 21 is larger than the diameter of the drive blade 14.

[0037] In one embodiment of the present invention, the bottom of the vent pipe 3 is slidably connected to the top of the isolation cover 21, the top of the partition plate 5 is fixedly installed with a sealing groove 15 located directly below the isolation cover 21, a sealing ring is provided inside the sealing groove 15, the bottom of the vent pipe 3 is higher than the jet pipe 17, and a valve located outside the tank body 1 is provided at the top of the vent pipe 3.

[0038] In one embodiment of the present invention, a bidirectional lead screw 23 located directly above the isolation cover 21 is rotatably connected to the top of the inside of the tank body 1. A pressure motor 24 located at one end of the bidirectional lead screw 23 is fixedly installed on the top of the inside of the tank body 1. The output end of the pressure motor 24 is fixedly installed to one end of the bidirectional lead screw. Two symmetrical moving blocks 25 are threadedly connected through the bidirectional lead screw. Support rods 26 are rotatably connected to both sides of the moving blocks 25. The other end of the support rods 26 is rotatably connected to the top of the isolation cover 21.

[0039] In one embodiment of the present invention, a fixing plate 4 located below the partition 5 is uniformly fixedly installed inside the tank body 1, the distance between adjacent fixing plates 4 is the same, and the top of the fixing plate 4 is filled with powdered magnesium-based hydrogen storage material.

[0040] In one embodiment of the present invention, the bottom of the stirring blade 13 is higher than the top of the heating plate 11, the width of the stirring blade 13 is less than half the distance between the adjacent fixed plates 4, and the stirring blade 13 is an inclined strip. By setting the stirring blade 13, when the heating plate 11 heats the magnesium-based hydrogen storage material, the hydrogen gas sprayed through the jet pipe 17 drives the blade 14 to rotate, thereby driving the stirring blade 13 to stir the heated magnesium-based hydrogen storage material, so that the magnesium-based hydrogen storage material can be fully heated and the stored hydrogen gas can be completely released.

[0041] It should be noted that during use, hydrogen enters the tank 1 through the inlet pipe 2 above the internal partition 5, then through the gas guide pipe 7 into the connecting pipe 6 and the dispersion pipe 8, and is sprayed out through the outlet 9 onto the powdered magnesium-based hydrogen storage material above the fixed plate 4. Several outlets 9 evenly distributed below the fixed plate 4 spray the hydrogen supplied by the inlet pipe 2 evenly onto the powdered magnesium-based hydrogen storage material, allowing the hydrogen to react fully with the magnesium-based hydrogen storage material, thereby increasing the device's hydrogen storage capacity. Hydrogen is then sprayed through the jet pipe 17 onto the drive blade 14, causing the drive blade 14 to rotate. This causes the drive blade 14 to rotate the rotating shaft 12, which in turn rotates the stirring blade 13, stirring the powdered magnesium-based hydrogen storage material above the fixed plate 4. This further ensures that the hydrogen reacts fully with the magnesium-based hydrogen storage material, further increasing the hydrogen storage capacity and enhancing the practical value of the device. When releasing hydrogen, the clamping motor 24 drives the bidirectional lead screw 23 to rotate, which in turn moves the moving block 25. This causes the support rod 26 to push the isolation cover 21 down to seal the sealing groove 15. At the same time, the sealing sleeve 27 moves down to expose the movable groove 16. Simultaneously, the connecting plate 18 and the connecting column 19 pull the sealing plate 20 down to seal it against the sealing ring 22. The heating plate 11 heats the magnesium-based hydrogen storage material, causing the hydrogen stored in the material to overflow. The overflowing hydrogen enters the isolation cover 21 through the movable groove 16 and the jet pipe 17, and then exits through the outlet pipe 3. When the heating plate 11 heats the magnesium-based hydrogen storage material, the hydrogen ejected through the jet pipe 17 drives the driving blade 14 to rotate, which in turn drives the stirring blade 13 to stir the heated magnesium-based hydrogen storage material, allowing the material to be fully heated and the stored hydrogen to be completely released.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
