Description

Technical Field

[0001] The present invention belongs to the technical field of hydrogen energy storage, and specifically relates to a hydrogen storage tank. Background Art

[0002] Hydrogen is a clean energy with great potential. The product of hydrogen combustion is only water, which will not produce pollutants such as carbon dioxide, sulfur dioxide, and nitrogen oxides, nor will it emit greenhouse gases, and is very friendly to the environment.

[0003] Although hydrogen has a relatively high mass energy, its density is small, making it not easy to store and transport. If you want to use hydrogen more efficiently, you need to store more hydrogen in a smaller volume.

[0004] In the prior art, the storage tank for hydrogen generally requires high pressure resistance, and there are certain requirements for the heat preservation performance of the tank. Especially after hydrogen is cooled to a liquid state at low temperature, if it is to be kept in a liquid state, the storage device must be kept in an ultra-low temperature environment, resulting in a high use cost. Moreover, since hydrogen molecules are very small, they will penetrate into the metal lattice, reducing the mechanical properties of the metal outer wall, causing hydrogen embrittlement, and also affecting the service life.

[0005] Although some existing storage tanks are provided with solid metal materials inside, for example, magnesium metal materials are often selected, and hydrogen storage is achieved by adsorbing hydrogen through the magnesium metal material. However, an oxide layer is easily generated on the surface of the magnesium metal material, and the oxide layer affects the efficiency of hydrogen entering the magnesium metal lattice. And treating the surface of the magnesium metal material by pickling and other methods is rather troublesome and increases the cost. Summary of the Invention

[0006] The purpose of the present invention is to provide a hydrogen storage tank that can reduce the cost of hydrogen storage.

[0007] To achieve the above purpose, the technical solution adopted by the present invention is a hydrogen storage tank, which includes a mixing tank body and a feeding component. A mixing chamber is arranged inside the mixing tank body. The feeding component is used to carry solid materials and transport the solid materials into the mixing chamber. A solid material treatment component is installed on the feeding component to couple the solid materials with the solid material treatment component. A heat conduction component is arranged in the mixing chamber. After the heat conduction component is docked with the solid material treatment component, a treatment chamber is formed in the mixing chamber, so that the solid materials, hydrogen, and the solid material treatment component are all located in the treatment chamber; A hydrogen circulation pipe head is arranged on the mixing tank body for inputting hydrogen into the treatment chamber, and a driving component is also arranged. The driving component is connected to the solid material treatment component and is used to control the operation of the solid material treatment component, so that the solid material treatment component can perform a cleaning treatment on the oxide layer on the surface of the solid material.

[0008] Furthermore, the feeding assembly includes a positioning part and a conveying platform. The positioning part is connected to the solid material processing assembly and is used to carry solid materials. The conveying platform is connected to the positioning part and is used to move the positioning part toward the mixing tank body so that the solid materials enter the mixing chamber.

[0009] Furthermore, the solid material processing assembly includes an auxiliary positioning frame and a pull rod. The auxiliary positioning frame is used to support and surface treat the solid material, and the solid material is in a rod shape; the pull rod is used to connect the auxiliary positioning frame with the positioning part, and the pull rod controls the auxiliary positioning frame to move linearly.

[0010] Furthermore, the auxiliary positioning frame is provided with a plurality of channels for passing the rod-shaped solid material, so that after the rod-shaped solid material passes through the channels, the ends of the rod-shaped solid material are connected to the positioning portion.

[0011] Furthermore, a scraper is provided on the auxiliary positioning frame, the scraper is located in the channel, the inner end of the scraper can be against the rod-shaped solid material, and when the auxiliary positioning frame moves, the scraper can remove the oxide layer on the surface of the rod-shaped solid material.

[0012] Furthermore, a positioning blind hole is provided on the positioning portion so that the end of the rod-shaped solid material can be located in the positioning blind hole. A clamping assembly is provided in the positioning blind hole, and the clamping assembly is used to clamp the rod-shaped solid material.

[0013] Furthermore, a driving assembly is provided on the positioning portion, and the driving assembly is used to control the rotation of the pull rod and the clamping assembly.

[0014] Furthermore, the solid material processing component includes a material distribution component, which is located in the processing chamber and connected to the positioning part, and is used to move the solid material in the processing chamber, and the solid material is in block shape.

[0015] Furthermore, the material dividing assembly includes a central shaft, spiral blades and a material shifting assembly. The central shaft is connected to the positioning portion. The central shaft rotates under control. The spiral blades are fixed on the central shaft to enable the block of solid material to move along the length direction of the central shaft. The material shifting assembly is fixed on the central shaft so that the block of solid material can be shifted through the material shifting assembly when the central shaft rotates.

[0016] Furthermore, the material dividing assembly also includes a separation cylinder, which is located in the processing chamber and divides the processing chamber into a processing space and an adsorption space, so that the spiral blade and the material dividing assembly are respectively located in the processing space and the adsorption space.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: By simultaneously transporting a solid material and hydrogen into a mixing tank body, and then pressurizing the internal environment of the mixing tank body, hydrogen enters the metal lattice of the solid material to form a hydride. This hydride is a solid under normal temperature and pressure, so there is no need to keep the mixing tank body in a high-pressure and low-temperature state all the time, and the hydrogen stored in the solid material will not affect the quality of the mixing tank body;

[0018] When hydrogen enters the solid material, the oxide layer on the surface of the solid material can be treated to increase the efficiency of hydrogen entering the internal lattice of the solid material. Similarly, the efficiency of hydrogen release can also be improved. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0035] Refer to Figures 1 to 4As shown in the figure, a hydrogen storage tank includes a mixing tank body 1 with a mixing chamber 2 inside. The mixing tank body 1 is installed on a base 3 and is connected to a pressurizing device 4. An input port and a hydrogen circulation pipe head 5 are also provided on the mixing tank body 1. When storing hydrogen, the solid material is conveyed through the input port into the mixing chamber 2 of the mixing tank body 1, and at the same time, hydrogen is input into the mixing tank body 1 through the hydrogen circulation pipe head 5. Conversely, when it is necessary to discharge the stored hydrogen, it can also be discharged through a gas transmission pipeline. After the hydrogen is input into the space where the solid material is located, the input port is closed, and the valve on the hydrogen circulation pipe head 5 is closed. At this time, the mixing tank body 1 is pressurized by the pressurizing device 4, so that the hydrogen in the mixing tank body 1 enters into the crystal walls of the solid material, thereby realizing the storage of hydrogen through the solid material.

[0036] A feeding assembly is provided on the base 3. The feeding assembly can send the solid material into the mixing tank body 1 through the input port of the mixing tank body 1. The feeding assembly includes a conveying table 601. A positioning part is installed on the conveying table 601. The solid material is placed on the positioning part. A rail groove is provided on the bottom surface of the conveying table 601, and a track 603 is provided on the base 3. The rail groove of the conveying table 601 cooperates with the track 603 on the base 3, so that the conveying table 601 can slide along the length direction of the track 603. When the conveying table 601 approaches the mixing tank body 1, the solid material on the positioning part is sent into the mixing tank body 1.

[0037] The positioning part is hinged to the conveying table 601. Specifically, a support arm 604 is provided on the conveying table 601, and the positioning part includes a cylindrical bearing main body 6021. The bearing main body 6021 is connected to the upper end of the support arm 604 through a shaft column. At this time, one end of the bearing main body 6021 is a hinged end, and the other end is a free end. The bearing main body 6021 can be turned over with the hinge as the base point. A positioning seat 6022 is connected to the free end of the bearing main body 6021. The positioning seat 6022 is also cylindrical. A solid material processing component is installed on the positioning seat 6022. A driving component is provided on the positioning seat 6022. The driving component can control the solid material processing component to work, and the surface of the solid material is polished through the solid material processing component. After the solid material processing component cooperates with the positioning seat 6022, the solid material is positioned. A heat conduction component is provided in the mixing tank body 1, and the heat conduction component includes a heat conduction disk 8. The heat conduction disk 8 is located in the mixing tank body 1. A positioning groove is provided on the heat conduction disk 8. There is a certain distance between the heat conduction disk 8 and the end of the mixing tank body 1, and a placement space is formed at this distance. A heating assembly 9 is installed in the placement space, and the heat conduction disk 8 is heated through the heating assembly 9, so that the temperature of the internal space of the mixing tank body 1 can reach a specified temperature value, which is beneficial to the entry of hydrogen into the solid material.

[0038] After completely transporting the solid material into the mixing tank 1, the solid material processing component and the heat conduction component cooperate to heat the solid material. At the same time, the pressure in the mixing tank 1 is adjusted in cooperation with the pressurizing device 4 so that hydrogen can be adsorbed by the solid material;

[0039] Refer to Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown in, Example 1, in this embodiment, the solid material fed by the feeding component is a magnesium rod. That is, the feeding component transports the magnesium rod material into the mixing tank 1, and then the magnesium rod adsorbs hydrogen, finally completing the solid-state storage of hydrogen. The solid material processing component in this embodiment includes an auxiliary positioning frame 701 and a pull rod 702. The pull rod 702 connects the auxiliary positioning frame 701 to the positioning seat 6022. There are at least three pull rods 702, and the three pull rods 702 need to be parallel to the central axis of the positioning seat 6022. The auxiliary positioning frame 701 moves on the pull rod 702. The specific moving direction is: moving towards or away from the positioning seat 6022. A number of channels 703 for passing through the magnesium rod are provided on the auxiliary positioning frame 701. At the same time, a number of positioning blind holes 6023 are provided on the positioning seat 6022. Each positioning blind hole 6023 and the corresponding channel 703 are on the same straight line. After passing the magnesium rod through the channels 703 on the auxiliary positioning frame 701, the auxiliary positioning frame 701 supports the magnesium rod, and the end of the magnesium rod can be inserted into the positioning blind hole 6023. At this time, the magnesium rod is carried, and then the magnesium rod is transported into the mixing tank 1 so that the end of the pull rod 702 is connected to the heat conduction disk 8. At this time, the magnesium rod is also connected to the heat conduction disk 8. In this embodiment, an outer cover cylinder 801 is provided on the heat conduction disk 8. When the magnesium rod is connected to the heat conduction disk 8, the solid material processing component is located inside the outer cover cylinder 801. At this time, the heat conduction disk 8 and the positioning seat 6022 on the feeding component form a processing chamber through the outer cover cylinder 801. An opening is provided on the outer cover cylinder 801, and this opening is connected to the hydrogen circulation pipe head 5 through a sealing short pipe, and hydrogen can be input into the outer cover cylinder 801.

[0040] At this time, the auxiliary positioning frame 701 is located between the heat conduction disk 8 and the positioning seat 6022, and the auxiliary positioning frame 701 can move towards the positioning seat 6022. Specifically, a guiding channel 7011 is provided on the auxiliary positioning frame 701, and a lead screw nut is provided in the guiding channel 7011. The pull rod 702 cooperates with the lead screw nut in the guiding channel 7011. At this time, the pull rod 702 is a driving lead screw. When the pull rod 702 rotates, it will drive the auxiliary positioning frame 701 to move. The moving direction of the auxiliary positioning frame 701 is related to the rotation direction of the pull rod 702;

[0041] A scraping member 704 is arranged in a channel 703 on the auxiliary positioning frame 701. The inner end of the scraping member 704 can abut against the magnesium rod. When the auxiliary positioning frame 701 moves towards or away from the positioning seat 6022, the oxide layer on the surface of the magnesium rod can be processed by the scraping member 704.

[0042] In this embodiment, the driving assembly includes a driving motor 10, a transmission assembly and a clamping assembly. The driving motor 10 is installed on the positioning seat 6022. The clamping assembly is arranged in the positioning blind hole 6023 of the positioning seat 6022. After the inner end of the magnesium rod is inserted into the positioning blind hole 6023, the magnesium rod is clamped and positioned by the clamping assembly. The driving motor 10 is connected to the clamping assembly and the driving lead screw through the transmission assembly. When the driving motor 10 works, the clamping assembly and the driving lead screw can be rotated, so that the magnesium rod can be rotated while the auxiliary positioning frame 701 moves, and the oxide layer on the surface of the magnesium rod is processed by the scraping member 704 on the auxiliary positioning frame 701.

[0043] The clamping assembly includes an anti - detachment chassis 1101. The anti - detachment chassis 1101 is located at the bottom of the positioning blind hole 6023. An inner sleeve body 1102 is arranged on the anti - detachment chassis 1101. At the same time, an outward - expanding groove 6024 is arranged at the bottom of the positioning blind hole 6023, so that the diameter of the bottom position of the positioning blind hole 6023 is larger than that of the upper part. At this time, both the anti - detachment chassis 1101 and the inner sleeve body 1102 are located in the outward - expanding groove 6024. A number of radially extending grooves are also arranged on the anti - detachment chassis 1101. The inner sleeve body 1102 is connected with a clamping plate 1104 through an elastic member 1103. The lower end of the clamping plate 1104 is located in the radially extending groove. At this time, the clamping plates 1104 are also in a number. The number of clamping plates 1104 is arranged in an array around the central axis of the anti - detachment chassis 1101. An arc - shaped transition part is arranged on the side of each clamping plate 1104 away from the inner sleeve body 1102. When the lower end of the magnesium rod is inserted between the clamping plates 1104, the lower end of the magnesium rod contacts the arc - shaped transition part on the clamping plate 1104, and then applies a thrust to the clamping plate 1104, so that the clamping plate 1104 moves towards the inner sleeve body 1102. Then, under the restoring force of the elastic member 1103, a reaction force is applied to the bottom end of the magnesium rod through the clamping plate 1104 to realize the clamping of the magnesium rod. A transmission short rod 1105 is fixed at the center of the anti - detachment chassis 1101. The free end of the transmission short rod 1105 is connected to the driving assembly, so that the clamping assembly can rotate.

[0044] The above - mentioned positioning seat 6022 is internally provided with a cavity. The cavity is communicated with the positioning blind hole 6023 through a shaft hole. The transmission short rod 1105 fixed on the anti - detachment chassis 1101 passes through the shaft hole. The transmission assembly is located in the cavity of the positioning seat 6022.

[0045] The transmission assembly includes a central gear disk 1201, an auxiliary gear disk 1202, and an end gear disk 1203. The central gear disk 1201 is docked with the output shaft of the drive motor 10. The rotation of the central gear disk 1201 is controlled by the drive motor 10. The auxiliary gear disk 1202 and the end gear disk 1203 are respectively docked with the transmission short rod 1105 and the drive lead screw. The auxiliary gear disk 1202 and the end gear disk 1203 are connected to the central gear disk 1201. Specifically, an auxiliary ring 1204 and an outer edge ring 1205 are provided on the central gear disk 1201. The auxiliary ring 1204 meshes with the auxiliary gear disk 1202, and the outer edge ring 1205 meshes with the end gear disk 1203. When the central gear disk 1201 rotates, it can drive the auxiliary gear disk 1202 and the end gear disk 1203 to rotate simultaneously, thereby rotating the magnesium rod and the drive lead screw. The surface of the magnesium rod is processed by the scraping member 704 on the auxiliary positioning frame 701;

[0046] The scraping rod 704 includes an intermediate positioning rod 7041. The end of the intermediate positioning rod 7041 has an insertion hole. An insertion rod 7042 is inserted into the insertion hole. A compression return spring 7043 is arranged in the insertion hole. The inner end of the insertion rod 7042 abuts against the compression return spring 7043. The outer end of the insertion rod 7042 is fixed with a scraping head 7044. The scraping head 7044 has a scraping surface. This scraping surface contacts the magnesium rod. An acting force is applied to the scraping head 7044 through the compression return spring 7043, so that the scraping surface of the scraping head 7044 can always contact the magnesium rod. A locking screw is connected to the middle position of the intermediate positioning rod 7041. The locking screw penetrates through the intermediate positioning rod 7041. A placement groove 7012 for placing the intermediate positioning rod 7041 is provided on the auxiliary positioning frame 701. A threaded blind hole is arranged in the placement groove 7012. When connecting the locking screw with the auxiliary positioning frame 701, the intermediate positioning rod 7041 is placed in the placement groove 7012, and then through the cooperation of the locking screw and the threaded blind hole, the locking and positioning of the intermediate positioning rod 7041 are realized.

[0047] The drive motor 10 in this embodiment is a stepper motor, which is connected with a pulse signal controller. The switch of the pulse signal controller is arranged on the end face of the positioning seat 6022. The auxiliary positioning frame 701 moves towards the positioning seat 6022. When the auxiliary positioning frame 701 contacts the switch, the output shaft of the stepper motor can rotate in the reverse direction. At this time, the auxiliary positioning frame 701 moves in the direction away from the positioning seat 6022. When the auxiliary positioning frame 701 moves to the end of the drive lead screw, the drive motor 10 can be controlled to stop working or the output shaft can rotate in the reverse direction again, so as to process the oxide layer on the surface of the magnesium rod to a certain extent and avoid the hindrance effect on hydrogen storage.

[0048] Refer to Figures 9 to 11As shown, in the second embodiment, in this embodiment, it is used to feed magnesium fragments, that is, the feeding component is used to transport magnesium fragments into the mixing tank body 1. The feeding component in this embodiment still includes a conveying table 601 and a positioning part. The positioning part includes a cylindrical bearing body 6021 and a positioning seat 6022. The positioning seat 6022 is also cylindrical. One end of the positioning seat 6022 is fixed with a main shaft rod 6025. An axial through hole is provided on the bearing body 6021. The main shaft rod 6025 on the positioning seat 6022 passes through the axial through hole. The main shaft rod 6025 and the axial through hole are respectively located at the centers of the positioning seat 6022 and the bearing body 6021. A driving motor 10 is fixed on the bearing body 6021 to enable the positioning seat 6022 to rotate. A material loading cylinder 6026 is installed on the positioning seat 6022. The material loading cylinder 6026 is butted on the end face of the positioning seat 6022. The free end of the material loading cylinder 6026 is in an open state, and magnesium fragment materials can be placed in the material loading cylinder 6026. The main shaft rod 6025 is butted with a driving component. The driving component in this embodiment is the driving motor 10. The solid material processing component is located in the material loading cylinder 6026 and is butted with the main shaft rod 6025. The solid material processing component in this embodiment includes a material distribution component 705 located in the material loading cylinder 6026. As the material loading cylinder 6026 is transported into the mixing tank body 1, the magnesium fragment materials also enter the interior of the mixing tank body 1. After the material loading cylinder 6026 is butted with the heat conduction disc 8, the space inside the material loading cylinder 6026 becomes a processing chamber. The material loading cylinder 6026 is provided with air passing holes. At this time, the hydrogen circulation pipe head 5 in this embodiment can be butted with the air passing holes on the material loading cylinder 6026 to input hydrogen into the material loading cylinder 6026. The material distribution component 705 is also connected to the heat conduction disc 8. The magnesium fragments in the material loading cylinder 6026 can be heated through the material distribution component 705;

[0049] The material distribution component 705 includes a central shaft body 7051 passing through the center of the positioning seat 6022. A spiral blade 7052 is fixed on the central shaft body 7051. An end position frame is butted at the open end of the material loading cylinder body 6026. A central hole is provided on the end position frame. The free end of the central shaft body 7051 is located in the central hole. At the same time, a partition cylinder 7053 is arranged in the material loading cylinder body 6026. The partition cylinder 7053 is a conical cylinder. The large-diameter end of the partition cylinder 7053 is connected to the material loading cylinder. At this time, the partition cylinder 7053 and the material loading cylinder body 6026 form a processing space 7054 and an adsorption space. Initially, the magnesium fragments are located in the processing space 7054. After the magnesium fragments are conveyed into the mixing tank body 1, the central shaft body 7051 is connected to the heat conduction component. The magnesium fragments are moved through the spiral blade 7052 on the central shaft body 7051. Specifically, the pitch of the spiral blade 7052 is larger at one end near the positioning seat 6022. As the spiral blade 7052 gradually extends towards the small-diameter end of the partition cylinder 7053, the pitch of the spiral blade 7052 gradually becomes smaller. At the same time, the diameter of the spiral blade 7052 is not fixed. According to the diameter of the spiral blade 7052, the spiral blade 7052 can be divided into two parts. One part is the straight guide part, and the other part is the squeezing part. The squeezing part is surrounded by the partition cylinder 7053. The diameter of the squeezing part of the spiral blade 7052 gradually becomes smaller. Specifically, the spiral blade 7052 gradually becomes smaller towards the small-diameter end of the partition cylinder 7053. In this way, the magnesium fragments can be squeezed in the processing space 7054 to make the magnesium fragment particles more uniform. Then the magnesium fragments enter the adsorption space. The magnesium fragments contact with hydrogen in the adsorption space. A material stirring component is arranged in the adsorption space. The material stirring component is fixed on the central shaft body 7051. So at this time, the material stirring component also rotates accordingly. The magnesium fragments in the adsorption space are stirred by the material stirring component to avoid excessive accumulation of the magnesium fragments. At the same time, by stirring the magnesium fragments, the contact effect between the magnesium fragments and hydrogen can be increased.

[0050] The feeding component includes a feeding wheel fixed on the central shaft body 7051. There are several feeding wheels, and the several feeding wheels are arranged along the length direction of the central axis. Each feeding wheel includes a fixed sleeve 70610 sleeved on the central shaft body 7051. A feeding blade 70612 is connected to the fixed sleeve 70610 through a lever 70611. The adsorption space in the loading cylinder 6026 is conical-columnar. The wall thickness of the loading cylinder 6026 at the part of the adsorption space is not uniform. The thickness of this part of the loading cylinder 6026 includes a variable section 60261 and a constant section 60262. The wall thickness of the variable section 60261 gradually decreases towards the heat conduction component, and the constant section 60262 is located at the end of the loading cylinder 6026, and the wall thickness of the constant section 60262 is uniform. When the processed magnesium fragments enter the adsorption space, the feeding blades 70612 on the feeding wheel move as the central shaft body 7051 rotates. The magnesium particles are stirred by the feeding blades 70612 to avoid accumulation, and as the magnesium particles are stirred by the feeding blades 70612, the magnesium particles move towards the uniform section;

[0051] Refer to Figure 12 As shown, a material receiving box 13 is arranged below the loading cylinder 6026. The material receiving box 13 is slidably connected to the loading cylinder 6026. The material receiving box 13 has an upper opening. A reset component is connected between the material receiving box 13 and the loading cylinder 6026. When the loading cylinder 6026 does not enter the mixing tank body 1, the reset component is in a natural state. The linear distance between the outer end of the material receiving box 13 and the positioning seat 6022 is greater than the length of the loading cylinder 6026. When the loading cylinder 6026 enters the mixing tank body 1 and until the material receiving box 13 contacts the heat conduction component, as the loading cylinder 6026 continues to enter the mixing tank body 1, the linear distance between the material receiving box 13 and the positioning seat 6022 gradually becomes smaller. At this time, the reset component has a restoring force. In this way, when the processing of the magnesium fragments is completed and the loading cylinder 6026 is moved outwards of the mixing tank body 1, under the action of the reset component, the position of the material receiving box 13 at this moment will be kept unchanged, and the magnesium fragments at the constant section 60262 in the loading cylinder 6026 will fall into the material receiving box 13 and then be taken out of the mixing tank body 1.

[0052] The reset component among them includes two collar rings 14 sleeved on the loading cylinder 6026. Both collar rings 14 are fixedly connected to the material receiving box 13. A positioning ring 15 is fixed on the loading cylinder 6026. A limiting rod is connected between the positioning ring 15 and one of the collar rings 14. A spring member 16 that generates a restoring force after being compressed is sleeved on the limiting rod. The limiting rod passes through the positioning ring 15 or the collar ring 14. When the limiting rod is fixedly connected to the collar ring 14, the limiting rod passes through the positioning ring 15, and when the limiting rod is fixed to the positioning ring 15, the limiting rod passes through the collar ring 14.

[0053] Finally, refer to Figure 13As shown, after the technical solution of the present application transports the solid material into the mixing tank 1, it is necessary to make the internal space of the mixing tank 1 in a sealed state. At this time, the positioning seat 6022 is docked with the input port of the mixing tank 1, and then the conveying platform 601 is locked. A traction seat 17 is provided at the bottom of the conveying platform 601, and a traction groove 18 is provided on the base 3. The traction groove 18 is located between the two tracks 603, and the extending direction of the traction groove 18 is the same as that of the tracks 603. The traction seat 17 is located in the traction groove 18. A traction motor 19 is provided on the base 3. The mixing tank 1 is located between the traction motor 19 and the conveying platform 601. A traction lead screw 20 is provided in the traction groove 18. The traction lead screw 20 is connected to the traction seat 17 and the traction motor 19. By controlling the rotation of the traction lead screw 20 through the traction motor 19, the traction seat 17 can be driven to translate, thereby adjusting the position of the conveying platform 601, so that the positioning seat 6022 can block the input port of the mixing tank 1.

[0054] After the hydrogen is adsorbed and stored by the solid material, the solid material can be placed in the mixing tank 1 of the present application. When it is necessary to release the hydrogen, the solid material can be heated, and at the same time, the solid material is processed by the solid material processing component, which helps to release the hydrogen.
