Description

Technical Field

[0001] This application relates to the field of hydrogen energy production technology, and in particular to a stable hydrogen production device with aluminum powder quantity control effect. Background Technology

[0002] Hydrogen energy is a clean and renewable energy source, characterized by high energy density and zero emissions. Since hydrogen can be produced in various ways, and the only waste generated during its use is water, it holds immense potential to reduce carbon emissions and address energy supply issues. With technological advancements and market development, hydrogen energy is expected to play an even more significant role in the future.

[0003] Hydrogen has a high energy density and is the main carrier for hydrogen energy utilization. Hydrogen needs to be stored before transportation. There are various existing storage methods, such as compression storage in high-pressure containers, low-temperature liquid storage of larger quantities of hydrogen through liquid hydrogen, and storage methods using materials that adsorb hydrogen through metal-organic frameworks or carbon nanotubes.

[0004] Among the above-mentioned material storage methods, hydrogen production is required first. Hydrogen production from molten aluminum has become one of the mainstream solutions due to its low cost. However, the molten aluminum hydrogen production solution still has many drawbacks, such as the violent reaction leading to unstable hydrogen production rate and hydrogen pressure, and the coexistence of reactants and products resulting in low hydrogen production rate.

[0005] Referring to the hydrogen production device and method disclosed in CN115057408A, the scheme described in the application document is that the hydrogen produced by extruding inert gas into the hydrogen production device greatly improves the problem of low hydrogen production rate caused by the coexistence of reactants and products, and at the same time alleviates the current situation of unstable hydrogen pressure. In addition, the application document also sets up porous mesh plates at different heights inside the hydrogen production device to fill aluminum powder and install aluminum rods to achieve uniform distribution of liquid, thereby achieving uniform distribution of hydrogen production area.

[0006] Regarding the aforementioned technologies, although the application document improves the problem of unstable hydrogen pressure inside the hydrogen production device, placing all aluminum powder together and evenly sprinkling water on the surface of all aluminum powder during hydrogen production still cannot effectively improve the problem of violent hydrogen production reaction, and easily leads to excessive consumption of aluminum powder. Based on this, the technology in the aforementioned application document can be improved to reduce the amount of aluminum powder in contact with water at one time, significantly improve the current situation of violent hydrogen production reaction, and further alleviate the problems of unstable hydrogen pressure and low hydrogen production rate. Summary of the Invention

[0007] In order to significantly improve the current situation of violent hydrogen production reaction and further alleviate the problems of unstable hydrogen pressure and low hydrogen production rate, this invention provides a stable hydrogen production device with aluminum powder quantity control effect.

[0008] The present invention provides a hydrogen pressing device with aluminum powder quantity control effect, which adopts the following technical solution: A hydrogen pressing device with aluminum powder quantity control effect includes a module box and module slots opened inside the module box, each module slot being closed; in addition, it also includes; The hydrogen production module is set in the module slot and the reaction plates inclined towards the center are fixed to both ends of the inner wall of the hydrogen production module. Correspondingly, the top wall of the hydrogen production module near both ends is evenly provided with water inlet holes corresponding to the reaction plates. Aluminum powder is placed at the bottom of the hydrogen production module. The feeding section is rotatably connected to the inner walls of the two opposite sides of the hydrogen production module and is set up for each reaction plate. By rotating, it transports the aluminum powder at the bottom of the hydrogen production module to the reaction plate in batches. The spray nozzles are positioned above both ends of the hydrogen production module, corresponding to the water inlet holes, to spray water onto the water inlet holes. The liquid cooling unit is set up for each hydrogen production module and is used to control the temperature of the hydrogen production module.

[0009] By adopting the above technical solution, the modular box serves as the main body for the hydrogen production reaction. The interior of the modular box is divided into multiple modular slots, with a hydrogen production module correspondingly installed in each slot. Each hydrogen production module serves as the basic unit for hydrogen production. Placing all hydrogen production modules simultaneously within the same modular box reduces the footprint and increases the overall hydrogen production rate. The hydrogen production reaction occurs inside the hydrogen production module, which is rectangular in shape. Technicians first place aluminum powder at the bottom of the module and place aluminum rods on the reaction plate. A rotating feeding unit continuously transports small amounts of aluminum powder onto the reaction plate, where it accumulates. Small droplets are continuously sprayed from the spray nozzle above, falling into the hydrogen production module through the water inlet and reacting with the aluminum powder and aluminum oxide on the reaction plate. The rods come into contact, producing aluminum hydroxide and water. Compared to the reaction of aluminum with acidic solutions, the reaction rate of aluminum with water is slower. Using the reaction plate as the main structure of the aluminum-water hydrogen production reaction, a small amount of water is continuously brought into contact with a small amount of aluminum powder, replacing the traditional direct contact between water and a large amount of aluminum powder. This greatly improves the problems of violent and uneven reaction and unstable gas pressure inside the device. The heat generated by the aluminum-water hydrogen production reaction is carried away by the liquid cooling plate through direct contact with the outer wall of the hydrogen production module, removing the heat inside the hydrogen production module through heat transfer. In summary, the above scheme reduces the amount of aluminum powder in each batch to reduce the amount of aluminum powder in contact with water, and continuously supplies aluminum powder to the reaction plate to ensure the supply of raw materials for the reaction, so that hydrogen is generated slowly and continuously. The supply of aluminum powder is controlled by controlling the rotation speed of the feeding section, thus achieving aluminum powder quantity control.

[0010] Optionally, the feeding section includes; The rotating shaft is horizontally set and its two ends are rotatably connected to the inner wall of the hydrogen production module. The outer wall of the hydrogen production module is provided with a rotating component that drives the rotating shaft. The rotating plates are distributed at equal intervals around the side wall of the rotating shaft, perpendicular to the tangent of the rotating shaft. The multiple rotating plates are distributed in a divergent manner, with one side of the rotating plate bent into a groove shape. The end of the rotating plate away from the rotating shaft is set close to the reaction plate.

[0011] By adopting the above technical solution, the rotating shaft and rotating plate are the simplest mechanisms to move the aluminum powder placed at the bottom of the hydrogen production module upwards. The rotating plate on the bottom side of the rotating shaft abuts against and inserts into the aluminum powder. The rotating shaft is driven to rotate by an externally installed rotating component, which in turn drives the rotating plate to rotate, lifting the aluminum powder onto the reaction plate. Based on this, the side of the rotating plate is protruded, making the rotating plate as a groove to ensure the transport capacity per batch. It should be noted that the external driving component can be a brushless motor. At the same time, in order to ensure that the motor housing occupies less space and improve space utilization, the brushless motor is vertically installed in the module box, and a bevel gearbox is installed between the brushless motor and the rotating shaft to change the output direction of the brushless motor. The motor housing of the brushless motor is attached to the outer wall of the hydrogen production module to increase space utilization. In addition, the brushless motor controls the rotation speed of the rotating shaft, thereby controlling the angular displacement speed of the rotating plate and realizing the supply of aluminum powder on the reaction plate. Optionally, each of the rotating plates is provided with an elastic element at the part connecting it to the rotating shaft, which contracts to tilt the rotating plate when it collides with the reaction plate.

[0012] By adopting the above technical solution, the rotating plate is generally made of metal. When the rotating plate transports aluminum powder, the aluminum powder easily sticks to the plate. When the rotating plate rotates above the reaction plate, gravity alone cannot guarantee that a sufficient amount of aluminum powder will fall off the plate. Furthermore, ensuring that the ends of the rotating plate and the reaction plate do not interfere with or collide further limits the amount of aluminum powder transported each time. Therefore, the rotating shaft is positioned closer to the bottom of the reaction plate, so that each rotating plate, when rotating to a position near the end of the reaction plate, can abut against the end of the reaction plate. The collision at the end of the reaction plate shakes the aluminum powder adhering to the rotating plate off onto the reaction plate, ensuring a sufficient amount of material is fed each time. It is important to note that the method of shaking off the aluminum powder is necessary; otherwise, the aluminum powder will accumulate on the rotating plate, leading to a decrease in the feeding capacity of the rotating plate. The lower the angle, the better. Furthermore, in order to solve the interference problem of the rotating shaft after the collision, an elastic element is set at the connection between the rotating shaft and the rotating plate. When the end of the rotating plate contacts the end of the reaction part, the rotating shaft continues to rotate. The elastic element gives the rotating plate a clearance distance, causing the rotating plate to tilt as a whole and fall against the end of the reaction plate. After falling, the elastic element, which has lost its restraining force, releases its elastic force and pushes the reaction plate back to its original position. A spring is more suitable as the elastic element. The connection between each rotating plate and the rotating shaft is hinged. A fixed plate perpendicular to the rotating shaft is fixed along the circumference of each rotating plate. A spring is set between the fixed plate and the rotating plate. One end of the spring abuts against the rotating plate, and the other end is fixed to the fixed plate. When the angle of the reaction plate changes, it will compress the spring, and the elastic force of the spring will be used to reset the rotating plate.

[0013] Optional, also includes; The material distribution plates are perpendicular to and fixed to the reaction plate. Multiple plates are evenly distributed along the length of the reaction plate. Correspondingly, the side of the reaction plate is raised and forms a groove for containing aluminum powder between it and the adjacent material distribution plates.

[0014] By adopting the above technical solution, the distribution plate divides the reaction plate surface into multiple slots along the length of the reaction plate, improving the plate's capacity to hold aluminum powder and facilitating the collection and even distribution of water spilled from the water inlet. Water falls into the hydrogen production module through the water inlet and is evenly distributed on the reaction plate. Without the distribution plate, the water slides down the reaction plate and accumulates at the downward-sloping end. After accumulating a certain amount, it easily slides down onto the aluminum powder at the bottom of the hydrogen production module, causing the same violent reaction problem as in traditional solutions. Furthermore, the water sliding to the bottom of the hydrogen production module and reacting with the aluminum powder reduces the contact between the rotating plate and the aluminum powder, affecting the supply of aluminum powder to the reaction plate. It should be noted that adjacent distribution plates should be placed close together to minimize the slot spacing on the reaction plate, ensuring that the water is evenly distributed within each slot due to the obstruction of the slot walls, reacting with the aluminum powder in each slot to generate hydrogen.

[0015] Optional, also includes; The packing plate is integral with the hydrogen production module and is hinged to the side wall of the hydrogen production module at its bottom. The side wall of the hydrogen production module has a packing port corresponding to the packing plate. When the hydrogen production reaction is in progress, the packing plate and the side wall of the hydrogen production module are on the same plane to seal the hydrogen production module.

[0016] By adopting the above technical solution, the side wall of the hydrogen production module is provided with a filling port for technicians to fill aluminum powder, and the filling plate is used as the main structure to seal the filling port. Under normal conditions of the aluminum-water hydrogen production reaction, the side wall of the hydrogen production module and the filling plate are on the same plane. The filling plate seals the inside of the hydrogen production module. As the reaction continues, the rotating plate supplies aluminum powder to the reaction plate. When the amount of aluminum powder decreases to the point that it affects the transport of the rotating plate, the technician rotates the filling plate around the hinge side away from the hydrogen production module to open the connection between the inside of the hydrogen production module and the outside. The technician can then fill the inside of the hydrogen production module with aluminum powder. An external filling port should be opened at the filling port part corresponding to each hydrogen production module in the module box. The structure of the filling plate needs to be explained. First, the bottom side of the filling plate should be set as the hinge side so that the filling port of the filling plate opens upwards and the opening angle is limited to prevent aluminum powder from sliding off the filling port after the filling plate is opened. In addition, the technician should open the filling plate slowly to avoid airflow disturbance blowing away the aluminum powder when the filling plate is opened.

[0017] Optionally, the liquid cooling section includes; The liquid cooling plate is the part that is set up and surrounds the bottom side, both ends and the corresponding reaction plate of the hydrogen production module. The inside of the liquid cooling plate is hollowed out to hold cold water.

[0018] By adopting the above technical solution, the liquid cooling plate is attached to the side wall of the hydrogen production module, and contacts the side wall of the hydrogen production module through heat transfer to absorb the heat released by the reaction inside the hydrogen production module. The aluminum-water hydrogen production reaction is an exothermic reaction, which releases a large amount of heat energy during the reaction process, and the reaction rate increases with the increase of temperature, causing the reaction to gradually become more intense. Therefore, the liquid cooling plate is set to reduce the ambient temperature of the reaction, and at the same time, it can also prevent excessively high temperatures from damaging the auxiliary devices and equipment of the hydrogen production module. In addition, cooling also helps to improve the selectivity of the reaction and reduce the occurrence of side reactions within the hydrogen production module. The above solution selects a metal plate as the contact heat transfer medium, which is attached to the outer wall of the hydrogen production module and the part where the hydrogen production reaction occurs. At the same time, the interior is hollowed out and filled with cold water with high heat capacity and high heat absorption capacity, which quickly absorbs and removes the heat released by the reaction, thereby effectively reducing the ambient temperature inside the hydrogen production module. In addition, cold water contact cooling is a relatively safe cooling method, which does not involve the base temperature or flammable and explosive substances, and has a low risk.

[0019] Optional, also includes; The outlet pipe is fixed at one end to the hydrogen production module and connected to the inside of the hydrogen production module at the other end. It passes through the liquid cooling plate and is used to export hydrogen from inside the hydrogen production module. The buffer chamber is located inside the side walls at both ends of the module box and is connected to the gas outlet pipe. The hydrogen gas flowing out of the gas outlet pipe is temporarily stored in the buffer chamber.

[0020] By adopting the above technical solution, a gas buffer chamber is formed by hollowing out the interior of both ends of the module box. The buffer chamber is connected to the interior of the hydrogen production module through the gas outlet pipe. The hydrogen produced by multiple hydrogen production modules distributed on the same vertical line is transported together to the buffer chamber to form a gas buffer situation. Structurally, this reduces the design cost. Designers only need to set gas collection pipes connecting the buffer chamber at both ends of the module box. In terms of hydrogen production efficiency, the buffer situation in the buffer chamber slows down the flow rate of hydrogen and inert gas, thereby ensuring the stability of the gas pressure inside the hydrogen production module and avoiding the instability of the hydrogen production module pressure under the rapid flow of hydrogen, which would cause a large amount of oxygen and alumina powder to flow in from the gas inlet.

[0021] Optional, also includes; The air inlet is located in the center of the top wall of the hydrogen production module and is connected to the air inlet pipe for introducing inert gas to expel hydrogen.

[0022] By adopting the above technical solution, the hydrogen produced in the hydrogen production process is a combustible gas. An inert gas forms an inert atmosphere within the hydrogen production module, diluting the hydrogen concentration to below the explosion limit. This, combined with a liquid cooling plate, reduces the risk of explosion. Furthermore, the introduction of inert gas reduces the presence of oxygen within the hydrogen production module, lowering oxidation reactions and protecting the materials and equipment within the device. Taking advantage of these inert gas features, in this solution, inert gas is introduced into the top wall of the hydrogen production module in a manner that does not interfere with the inlet vent. Simultaneously, water mist is sprayed from a spray nozzle, and the gas flows directly into the hydrogen production module through a pipeline. The hydrogen produced within the inert gas system is then utilized. The inert gas should be delivered slowly and intermittently. The extruded hydrogen and inert gas are collected in the outlet pipeline and separated using a low-cost adsorption separation method. The inert gas is reused, while the hydrogen is collected and stored a second time. In practical applications, argon is recommended as the more widely used inert gas.

[0023] In summary, this application includes at least the following beneficial technical effects: 1. This design utilizes a rotating mechanism with the lowest design cost and simplest design to achieve batch transportation of aluminum powder. The reaction plate serves as the new load-bearing structure for the hydrogen production reaction. This improves upon the problems of traditional solutions where large amounts of aluminum powder directly contact water, leading to violent reactions, unstable internal gas pressure in the hydrogen production module, and excessive consumption of aluminum powder. This solution uses rotating plates to transport aluminum powder stored inside the hydrogen production module. A brushless motor drives a rotating shaft, which in turn drives multiple rotating plates to rotate. These plates sequentially and continuously contact the aluminum powder, transporting it to the reaction plate. Droplets from the spray nozzle are evenly sprayed onto the reaction plate through water inlets, thus achieving slow and continuous contact between water and aluminum powder on the reaction plate. This reduces the intensity of the aluminum powder reaction and alleviates the problem of excessive aluminum powder consumption. 2. Both the reaction plate and the rotating plate are grooved. The grooved shape of the rotating plate as a whole can ensure the amount of aluminum powder transported by a single rotating plate in a single operation. Correspondingly, the multiple closely spaced distribution plates on the reaction plate divide the reaction plate into multiple narrow grooves. After the rotating plate places the aluminum powder on the reaction plate, it is conducive to the uniform distribution of the aluminum powder on the reaction plate. In addition, water droplets falling from the water inlet are evenly distributed between adjacent distribution plates through the distribution plates, preventing water from accumulating at the downward tilt of the reaction plate and achieving uniform hydrogen production reaction. 3. A buffer chamber is created by hollowing out the inner wall of the module box to collect the hydrogen and inert gas flowing from the hydrogen production module, forming a gas buffer. This reduces the hydrogen flow rate while ensuring sufficient gas inside the hydrogen production module, and also reduces the amount of inert gas used, thus reducing the cost of hydrogen production. In addition, setting up a buffer chamber can save on the structure of hydrogen collection, which only requires setting collection pipes at both ends of the module box, without the need for a one-to-one design for each hydrogen production module.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] This application discloses a hydrogen pressing device with aluminum powder quantity control effect. (Refer to...) Figure 1 and Figure 2 A hydrogen-stabilizing device with aluminum powder control includes a module box 1. In this embodiment, the module box 1 is generally rectangular in shape and hollowed out into a shell. A perforated plate 11 is horizontally arranged in the middle of the height of the module box 1, and another perforated plate 11 is vertically arranged in the middle of the length of the module box 1. The middle parts of the two perforated plates 11 intersect, dividing the interior of the module box 1 into four module slots 12. Each module slot 12 is used to hold a hydrogen production module 2. The hydrogen production module 2 serves as the main structure for hydrogen production. Multiple hydrogen production modules 2 are uniformly placed in the module box 1, that is, the hydrogen produced by multiple hydrogen production modules 2 is collected in a unified manner, reducing the hydrogen collection cost. Only the module box 1 is used as a unit to set up a collection pipe 16.

[0032] For ease of illustration, this embodiment only has four module slots 12 in a module box 1. In actual application, the number of module slots 12 and corresponding hydrogen production modules 2 is not limited to four, but the expansion of their number is limited to the vertical direction, that is, the height direction of module box 1. By increasing the height of module box 1, a mesh plate 11 is erected to form a new module slot 12.

[0033] Reference Figure 1 and Figure 2 In this embodiment, buffer cavities 13 are hollowed out on the inner walls at both ends of the module box 1. A gas outlet pipe 14 is fixed horizontally to the end wall of the hydrogen production module 2 closest to the buffer cavity 13. The gas outlet pipe 14 penetrates the inner wall of the module box 1 and connects the interior of the hydrogen production module 2 with the buffer cavity 13, providing a hydrogen production channel to draw the hydrogen produced inside the hydrogen production module 2 into the buffer cavity 13 for buffering. The buffer cavity 13, by buffering the hydrogen produced by the hydrogen production module 2, slows down the hydrogen production rate of the hydrogen production module 2. By slowing down the hydrogen flow rate, the internal gas pressure of the hydrogen production module 2 is stabilized, allowing a large amount of air to continuously flow into the hydrogen production module 2, thus reducing the hydrogen concentration and increasing the degree of oxidation reaction between the aluminum powder and oxygen in the air.

[0034] Reference Figure 2 It should be noted that the buffer chamber 13 in this embodiment can simultaneously buffer the hydrogen produced in multiple hydrogen production modules 2 on the same side of the module box 1, so as to reduce the hydrogen collection cost. Corresponding to the expansion of the number of module slots 12 in the height direction of the module box 1, the hydrogen production modules 2 installed after the expansion only need to connect the gas outlet pipe 14 to the buffer chamber 13 so that the buffer chamber 13 can maintain the buffering of the airflow in the hydrogen production modules 2 on the same side.

[0035] Reference Figure 3 and Figure 4 The hydrogen production module 2 is generally rectangular. Multiple water inlet holes 21 are provided near both ends of the top wall of the hydrogen production module 2. Multiple water inlet holes 21 are evenly distributed at each end of the top wall of the hydrogen production module 2. Inside the module tank 12, above both ends of the hydrogen production module 2, a vertically downward-facing spray head 22 is installed. The head of the spray head 22 faces the water inlet hole 21, and the tail is connected to a clean water tank (not shown in the figure) via a pipe. The clean water tank supplies cold water required for the aluminum-to-hydrogen reaction to the spray head 22. The cold water is dispersed into small droplets by the spray head 22 and sprinkled onto the water inlet holes 21 on both sides of the top wall of the hydrogen production module 2. The water then drips evenly through the multiple water inlet holes 21 into the interior of the hydrogen production module 2, contacting the aluminum powder and reacting. This process achieves uniform water distribution in the aluminum-to-hydrogen reaction.

[0036] Reference Figure 4 Both ends of the inner wall of the hydrogen production module 2 are fixed with a reaction plate 23 that is inclined downward toward the center. Each reaction plate 23 is located inside the hydrogen production module 2 below the water inlet 21. Multiple distribution plates 231 perpendicular to the top side of the reaction plate 23 are fixed to the top side of the reaction plate 23. The multiple distribution plates 231 are evenly distributed along their length direction, and adjacent distribution plates 231 are distributed at a predetermined distance. Corresponding to the distribution plates 231, each side of the reaction plate 23 is fixed with a side edge perpendicular to the surface of the reaction plate 23. Multiple narrow grooves are formed between the side edge of the reaction plate 23 and the adjacent distribution plate 231.

[0037] Aluminum powder is placed at the bottom of the hydrogen production module 2. In this embodiment, the aluminum powder is fed to the reaction plate 23 in batches and in quantitative quantities by the feeding part 24. Water droplets sprayed by the spray head 22 fall into the hydrogen production module 2 through the water inlet 21, are evenly distributed on each narrow groove on the reaction plate 23, and are blocked by each distribution plate 231 and accumulated in the narrow groove. At the same time, they come into contact with the aluminum powder transported to the reaction plate 23 by the feeding part 24 and undergo a chemical reaction in each narrow groove to produce hydrogen.

[0038] Reference Figure 3 and Figure 4 In this embodiment, the feeding section 24 includes a rotating shaft 241 corresponding to each reaction plate 23. Two rotating shafts 241 are horizontally rotatably connected to the lower end of each reaction plate 23 at the inclined downward end. Generally speaking, the two rotating shafts 241 are arranged in the middle part of the hydrogen production module 2. Multiple rotating plates 242 are arranged on the rotating shaft 241. The plate surface of the rotating plates 242 is radially distributed parallel to the cross section of the rotating shaft 241. The multiple rotating plates 242 are distributed in a divergent manner around the rotating shaft 241. The side of the rotating plate 242 away from the rotating shaft 241 is curved and bends in the opposite direction to the rotation of the rotating shaft 241, forming a spoon shape, which is used to ensure the amount of aluminum powder conveyed by a single rotating plate 242.

[0039] Reference Figure 3 The outer wall of the hydrogen production module 2 is equipped with a brushless motor 243 for driving the rotating shaft 241. In order to save internal space of the module box 1, the motor housing of the brushless motor 243 is fixed to the part of the outer wall of the hydrogen production module 2 corresponding to the rotating shaft 241. The output direction is changed by the helical bevel gear set 244 and connected to the end of the rotating shaft 241.

[0040] Therefore, the operating principle of the rotating shaft 241 and the rotating plate 242 is explained. The brushless motor 243 drives the two rotating shafts 241 to rotate simultaneously toward their respective reaction plates 23, thereby driving multiple rotating plates 242 to rotate simultaneously. The rotating plate 242 below the rotating shaft 241 abuts against the aluminum powder and holds a fixed amount of aluminum powder through the bending structure. After the rotating plate 242 rotates to the top, the aluminum powder falls onto the reaction plate 23 as the rotating plate 242 tilts, completing the directional batch feeding of the reaction plate 23.

[0041] Reference Figure 4 and Figure 5 The operator can control the output speed of the brushless motor 243 to reduce the feeding frequency of the reaction plate 23 and achieve quantity control. However, considering that aluminum powder, as a metal powder, is easily adsorbed on the rotating plate 242 and affects the supply of aluminum powder on the reaction plate 23, in this embodiment, the connection between the rotating plate 242 and the rotating shaft 241 is changed to a hinge. The side of the rotating plate 242 near the rotating shaft 241 is set as the hinge side, and a fixing plate is set for each rotating plate 242 and fixed to the end of the rotating plate 242. A spring 245 is fixed between the fixing plate and the rotating plate 242.

[0042] Reference Figure 4 and Figure 5 The state shown in the figure is the initial state, with the rotating plate 242 parallel to the radial direction of the section of the rotating shaft 241 and parallel to the fixed plate, and the spring 245 in a relaxed state.

[0043] The necessity of setting the spring 245 in this embodiment is that the elastic element can shake the aluminum powder adhering to the rotating plate 242 onto the reaction plate 23 by the collision between the end of the rotating plate 242 and the end of the reaction plate 23. Correspondingly, the rotating shaft 241 should be set close to the lower part of the reaction plate 23. However, in order to avoid interference between the rotation of the rotating plate 242 and the rotating shaft 241 during the collision, the spring 245 is set to give the rotating plate 242 a certain angular displacement as a clearance distance. When the end of the rotating plate 242 hits the end of the reaction plate 23, the rotating plate 242 receives the rigid support of the reaction plate 23 and rotates relative to the rotating shaft 241, causing the spring 245 to be compressed. When the spring 245 is compressed to a certain distance and rotates a certain distance with the rotating shaft 241, the rotating plate 242 detaches from the end of the reaction plate 23. The rotating plate 242 transports the aluminum powder to the reaction plate 23 and shakes the aluminum powder onto the reaction plate 23 by the collision.

[0044] Reference Figure 4 It should be noted that, since the end of the rotating plate 242 is curved, in this embodiment, the collision is achieved by the contact between the two sides of the rotating plate 242 and the side of the reaction plate 23. In addition, an end plate extends from the end of the reaction plate 23 along the tangent direction parallel to the rotation of the rotating shaft 241 at the contact point. The extended end plate of the reaction plate 23 contacts the rotating plate 242, and the plate surface is parallel to the direction of force transmission during the collision, which weakens the collision effect and ensures the structural stability of the reaction plate 23.

[0045] In this embodiment, by dividing the reaction plate 23 into slots, the droplets falling from the water inlet 21 and the aluminum powder conveyed from the rotating plate 242 are evenly distributed in each slot, thus preventing the aluminum powder and water from sliding directly down the inclined reaction plate 23 and accumulating at the end of the reaction plate 23.

[0046] Reference Figure 3 and Figure 4 In this embodiment, an inlet for conveying inert gas is provided in the center of the top of the hydrogen production module 2, and an inlet pipe 25 is fixedly connected to the inlet. Taking advantage of the chemical stability of inert gas, inert gas is slowly and intermittently conveyed into the hydrogen production module 2 to squeeze out the hydrogen produced inside. The hydrogen is then conveyed unidirectionally to the buffer chamber 13 through the inert gas. After the gas is output from the buffer chamber 13 through the collection pipe 16, the hydrogen and inert gas are separated by adsorption separation. The inert gas is re-transported into the hydrogen production module 2 for recycling, while the hydrogen is stored.

[0047] Reference Figure 3In this embodiment, a liquid cooling plate 26 is installed inside the module slot 12, attached to the outer wall of the hydrogen production module 2. The liquid cooling plate 26 is attached to the end walls, bottom wall, and side walls of the hydrogen production module 2 near the reaction plate 23. The interior of the liquid cooling plate 26 is hollowed out and filled with cold water. The liquid cooling plate 26 is made of metal and uses the metal plate as a heat transfer medium to absorb the heat generated by the hydrogen production reaction through physical cooling, preventing the internal temperature of the hydrogen production module 2 from rising and accelerating the reaction, and reducing the possibility of hydrogen explosion. The liquid cooling plate 26 should be connected to a water pipe connected to a cold water tank to intermittently supply cold water.

[0048] Looking back Figure 2 Each hydrogen production module 2 has a filling port at its bottom, and a corresponding filling plate 27 is hinged to it. The diameter of the filling plate 27 is equal to that of the filling port. The bottom side of the filling plate 27 is hinged to the bottom side of the corresponding filling port of the hydrogen production module 2. With the bottom side of the filling plate 27 as the rotation side, the filling plate 27 can rotate around the rotation side at a certain angle away from the filling plate 27. Correspondingly, the module box 1 has an external filling port for each filling port of the hydrogen production module 2, and an external filling plate 15 is provided to close the external filling port. When the aluminum-water hydrogen production reaction occurs, both the filling port and the external filling port are in a closed state. When aluminum powder needs to be added to the hydrogen production module 2, the technician opens the external filling port and slowly rotates the filling plate 27 along the bottom side of the filling port to add aluminum powder into the hydrogen production module 2, then slowly closes the filling port, and then closes the external filling plate 15.

[0049] It should be noted that in this embodiment, in order to protect the aluminum powder stored inside the hydrogen production module 2 and to prevent technicians from pulling the packing plate 27 at too large an angle, the design of the packing plate 27 should have an angle limitation, that is, to prevent technicians from rotating the packing plate 27 at too large an angle, so that the external airflow will affect the distribution of aluminum powder inside the hydrogen production module 2. However, no limitation is made on the outer packing plate 15.

[0050] The implementation principle of the hydrogen production device with aluminum powder quantity control in this embodiment is as follows: In this embodiment, the hydrogen production module 2 is used as the basic unit for producing hydrogen. Multiple hydrogen production modules 2 are uniformly placed in the module box 1 for unified collection, thereby reducing the collection cost of hydrogen.

[0051] A brushless motor 243 drives two rotating shafts 241 to rotate simultaneously toward their respective reaction plates 23, thereby driving multiple rotating plates 242 to rotate simultaneously. The rotating plates 242 below the rotating shafts 241 abut against the aluminum powder and hold a fixed amount of aluminum powder through a bending structure. After the rotating plates 242 rotate to the top, the aluminum powder falls onto the reaction plates 23 as the rotating plates 242 tilt. When the end of the rotating plates 242 hits the end of the reaction plates 23, the rotating shafts 241 maintain their original speed, causing the springs 245 to compress. By setting the springs 245, the rotating plates 242 are given a certain angular displacement as a clearance distance. When the springs 245 are compressed to a certain distance and rotate a certain distance with the rotating shafts 241, the rotating plates 242 detach from the end of the reaction plates 23. The rotating plates 242 transport the aluminum powder to the reaction plates 23 and shake the aluminum powder onto the reaction plates 23 through impact.

[0052] The reaction plate 23 is divided into slots, and the droplets falling from the water inlet 21 and the aluminum powder conveyed from the rotating plate 242 are evenly distributed in each slot. They come into contact with each slot on the reaction plate 23 and react. The operator can control the output speed of the brushless motor 243, thereby reducing the feeding frequency of the reaction plate 23 and achieving quantity control.

[0053] Then, inert gas is delivered into the hydrogen production module 2 through the air intake pipe 25 to squeeze out the hydrogen produced inside. The hydrogen is then transported unidirectionally to the buffer chamber 13 through the inert gas. After the gas is output from the buffer chamber 13 through the collection pipe 16, the hydrogen and inert gas are separated by adsorption separation. The inert gas is then transported back into the hydrogen production module 2 for recycling, while the hydrogen is stored.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
