Description

Technical Field

[0001] The present invention relates to the field of battery technology, and particularly to a metal-air fuel cell system for large-size anode tracking adjustment.

Background Art

[0002] Metal-air fuel cells have advantages such as low cost, non-toxicity, non-pollution, discharge voltage stability, high safety, high specific energy, and high specific output. Our country has abundant metal resources such as metals like magnesium, aluminum, and zinc, all of which can be used as the anode of metal-air fuel cells and can gradually develop into a new energy with great development and application prospects. In recent years, with the development and completion of several theoretical processes, the application of metal-air fuel cells has become increasingly widespread in fields such as energy storage, national defense, and transportation equipment, and it also has extremely great development potential among several emerging energy industries.

[0003] Conventional metal-air fuel cells often use a metal plate as the battery anode. Due to the limitation of the size of the metal plate, it is necessary to frequently replace the anode, and time and energy are consumed in the process of processing the metal ingot into a metal plate. If a large-size standard cubic metal ingot is directly used as the metal battery anode, the defects of the metal plate can be compensated. However, current metal batteries still often adopt a rigidly fixed battery box. As the chemical reaction progresses, the volume of the metal ingot gradually shrinks while the size of the battery box remains unchanged, the distance between the surface of the metal ingot and the inner wall of the battery box where the air electrode is embedded becomes larger, the electrochemical reaction rate significantly decreases, the sustainability and stability of the electrochemical reaction cannot be guaranteed, and it has a serious impact on the performance of the metal-air fuel cell. This is also a major technical obstacle to the popularization and application of large-size metal-air fuel cells.

Embodiments for Carrying Out the Invention

[0017] Hereinafter, while referring to the drawings in the embodiments of the present invention, the technical aspects in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present invention.

[0018] The object of the present invention is to solve the problems existing in the above-mentioned prior art, realize real-time size adjustment through a tracking adjustment mechanism based on the size change of the metal ingot in the reaction process, ensure the sustainability and stability of the electrochemical reaction, and provide a metal-air fuel cell system for large-size anode tracking adjustment that can improve the performance reliability of the metal-air fuel cell.

[0019] In order to make the above objects, features, and advantages of the present invention clearer and easier to understand, the present invention will be further described in more detail below by combining the attached drawings and specific embodiments.

[0020] <Term Explanation> Follow-up adjustment system: Also known as a servo system or tracking system, the follow-up adjustment system is a feedback adjustment system in which the input amount of the follow-up adjustment system changes randomly, and the output amount of the system changes with a constant precision according to the change in the input amount. Metal-air fuel cell: A special type of fuel cell that uses metal as fuel and generates electrical energy through an oxidation-reduction reaction with oxygen in the air. Electrolyte: The electrolyte is a medium used in chemical batteries, electrolytic capacitors, etc., and in this invention, the electrolyte is a 10% sodium chloride solution. Standard cubic metal ingot: A standard cubic metal with sides measuring 1 meter and a purity of 99.9%.

[0021] As shown in Figures 1, 2, and 6, the present invention includes a flexible rubber housing 1 for housing an electrolyte and a metal ingot 24. The present invention employs a large cubic metal ingot as the anode, the flexible housing 1 serves as an electrochemical reaction space, and the inner wall of the flexible housing 1 incorporates a flexible air electrode as the cathode. A follow-up adjustment module is connected to the side wall of the flexible housing 1, which can change the shape of the flexible housing 1 in accordance with the dimensional changes of the metal ingot 24, thereby reducing the dimensions of the electrochemical reaction space. A drive mechanism is used to control the operation of the follow-up adjustment module. The present invention directly uses a large standard cubic metal ingot as the battery anode, and its housing is manufactured from flexible rubber material. In cooperation with the follow-up adjustment system, the shape of the housing can be adjusted in real time according to the size of the metal ingot, ensuring the sustainability and stability of the electrochemical reaction process and solving the technical problem in which the performance of large metal batteries gradually deteriorates as the reaction progresses.

[0022] Specifically, the flexible housing 1 is a topless, rounded-corner rectangular housing manufactured by molding flexible rubber material, and is the core component of the entire apparatus. A follow-up adjustment mechanism allows it to change shape in real time according to changes in the size of the metal ingot, ensuring the persistence and stability of the reaction process. A circulating electrolyte interface 4 is opened in one corner of the bottom of the flexible housing 1, and the circulating electrolyte interface 4 is externally connected to an electrolyte circulation system to discharge excess electrolyte solution during the housing deformation process and to perform precipitation purification under certain conditions. As shown in Figure 7, the electrolyte circulation system includes a water tank 22 and a sedimentation tank 23. The electrolyte circulation interface 4 communicates with the water tank 22 via a first water supply pipe, the water tank 22 communicates with the flexible housing 1 via a first return water pipe, the water tank 22 communicates with the lower part of the sedimentation tank 23 via a second water supply pipe, and the water tank 22 communicates with the upper part of the sedimentation tank 23 via a second return water pipe. Water pumps 27 are provided in the first water supply pipe, the first return water pipe, the second water supply pipe, and the second return water pipe. The reaction tank is connected to the circulation system by the circulating electrolyte interface 4. The water tank serves as a temporary storage space for the electrolyte and simultaneously performs sedimentation and purification when certain conditions are met, ensuring that the electrochemical reaction proceeds efficiently and stably.The driven adjustment module includes four rigid support rods 5 fixedly inserted into vertical through holes 3 opened in the center of the four side walls of the flexible housing 1, each rigid support rod 5 having a slider fixedly connected to its bottom, each slider having an axial threaded through hole along the direction of the lead screw 6, and a horizontally positioned lead screw 6 is screwed into the threaded through hole, converting the rotational motion of the lead screw 6 into the translational motion of the rigid support rod 5, one end of the lead screw 6 being dynamically connected to a drive mechanism, the drive mechanism including a drive motor 9, the drive motor 9 being dynamically connected to a drive bevel gear 11 via a coupling 10, and the drive bevel gear 11 is A drive mechanism engages with a horizontally positioned driven bevel gear 12, with a disc bevel gear 8 coaxially mounted above the driven bevel gear 12. A compression bevel gear 7 is fixedly mounted to one end of a rigid support rod 5, and each of the four compression bevel gears 7 is electrically connected to the disc bevel gear 8. The rigid support rod 5 acts as a direct biasing member for the deformation of the housing, allowing the drive mechanism to rotate the lead screw 6. As the lead screw 6 rotates, the screwed slider moves horizontally along the lead screw 6. Furthermore, under the action of the lead screw 6, the four rigid support rods 5 can move toward the center, pushing the housing wall inward to cause elastic deformation.

[0023] To make the mounting of the transmission mechanism more robust and reliable, the present invention uniquely designs a first base plate 13 and a second base plate 21. As shown in Figures 4 and 5, the bottom of the first base plate 13 is fixedly connected to the second base plate 21 via a plurality of telescopic support rods 16. Guide grooves 14 extending towards the center are provided in all four side walls of the first base plate 13, and four rigid support rods 5 are vertically movable and installed correspondingly within the four guide grooves 14. A compression bevel gear outer bearing base 15 is fixedly attached to the lower outside of the guide grooves 14, and a compression bevel gear bearing that connects to a compression bevel gear is mounted on the compression bevel gear outer bearing base 15. A disc bevel gear bearing base 18 is attached to the inner bottom of the first bottom plate 13, and a driven bevel gear bearing base 17 is attached coaxially to the disc bevel gear bearing base 18 on the top of the second bottom plate 21. The disc bevel gear bearing base 18 and the driven bevel gear bearing base 17 are used to connect the disc bevel gear shaft and the gear shaft of the driven bevel gear. A drive bevel gear bearing base 19 is provided on the side of the driven bevel gear bearing base 17, and a drive motor mounting through hole 20 is provided in the second bottom plate on the outside of the drive bevel gear bearing base 19. The drive motor mounting through-hole 20 is connected to the drive motor 9 via bolts, and each bevel gear structure and the drive motor 9 can be mounted at corresponding positions on the bottom plate. The first bottom plate 13 is positioned below the flexible housing 1, and the bottom surface of the flexible housing 1 is supported by the first bottom plate 13, preventing the bottom surface of the housing from bulging downwards during the deformation process. The rigid support rod 5, which penetrates the rubber housing, passes through the guide groove 14 and meshes with the lead screw 6. The guide groove 14 acts as a guide for the translational motion of the rigid support rod 5, restricting the support rod from moving only in the direction of the groove. The telescopic support rod 16 is used to adjust the spacing between the two layers of the bottom plate in order to facilitate the assembly of the drive mechanism.

[0024] Referring to Figure 3, the transmission calculation for the drive mechanism is explained as follows. Let n0 be the rotational speed of the drive motor. Since the drive bevel gear is connected to the drive motor shaft via a coupling, its rotational speed is n1 = n0. If the transmission ratio between the drive bevel gear and the driven bevel gear is i1, then the rotational speed n2 of the driven bevel gear satisfies the following relationship.

[0025]

number

[0026] Since the driven bevel gear and the disc bevel gear are fixed and continuous on the same axis, if the rotational speed of the disc bevel gear is n3 = n2 and the transmission ratio between the disc bevel gear and the four compression bevel gears is i2, then the rotational speed of the compression bevel gear n4 satisfies the following relationship.

[0027]

number

[0028] Since the compression bevel gear is fixed and continuous with the screw, if the lead screw rotation speed n5 = n4 and the lead of the lead screw is d, then the horizontal movement speed v of the support rod, which is the linear motion speed of the nut, is as follows.

[0029]

number

[0030] By combining the above equations, we obtained a relationship between the horizontal movement speed v of the support rod and the motor rotation speed n0.

[0031]

number

[0032] More preferably, slide grooves 2 are provided at the four corners of the tip of the flexible housing 1, a fixed bracket 25 is installed above the flexible housing 1, a camera 26 is movably mounted on the fixed bracket 25, a controller is connected to the camera 26, the controller is electrically connected to the drive mechanism, a temperature sensor, a flow velocity sensor and a viscosity sensor are built into the circulating electrolyte interface 4, the temperature sensor, flow velocity sensor and viscosity sensor are electrically connected to the controller, a conventional microcontroller MCU is used as the controller, the metal ingot 24 is fixedly installed to the lower end of the fixed bracket 25 by bolts, four horizontal connecting rods are fixedly connected to the side wall of the fixed bracket 25, the horizontal connecting rods are located in the slide grooves 2, and inside the fixed bracket 25, wires are embedded to connect the air electrodes embedded in the wall surface of the flexible housing 1 to the metal ingot and to conduct a circuit, the camera 26 can rotate 360 ​​degrees around the mounting rod on the fixed bracket 25 and is used to collect image information and determine the reaction state of the metal ingot 24 and the distance between the metal ingot and the housing.

[0033] The basic control principle of this invention is as follows: A sensor collects information such as electrolyte temperature, flow rate, viscosity, and motor rotation speed; a camera collects data on the metal ingot and wall spacing and inputs it to the controller MCU; the MCU processes this data, compares the current spacing with a preset expected value, and sends command information to the drive motor and water pump based on its built-in algorithm; the drive motor receives the command and adjusts its operating state; a transmission mechanism connected to it transmits the rotation of the drive motor and converts it into movement of the rigid support rod 5, thereby changing the shape of the flexible housing 1 and enabling size adjustment of the flexible housing 1. On the other hand, when the flexible housing 1 is compressed, the MCU controls the water pump 27 between the reaction vessel and the water tank 22 inside the flexible housing 1 to suck excess electrolyte from inside the flexible housing 1 into the water tank; and when the shape of the flexible housing 1 is restored, the water pump 27 re-pumps the electrolyte from the water tank 22 into the flexible housing 1. When the viscosity data from the viscosity sensor exceeds a certain threshold, the MCU issues a command to the water pump 27 between the water tank and the sedimentation tank 23, pumping the metal hydroxide suspension in the water tank 22 to the sedimentation tank 23 to settle, and returning the supernatant to the water tank 22 as the reserve liquid for the reaction vessel in the flexible housing 1.

[0034] <Example 1> In this embodiment, using metallic magnesium as a specific example, the maximum internal space of the flexible housing 1 at the initial state, when the electrochemical reaction has not yet started and no elastic deformation has occurred, is considered to be the maximum size that can accommodate a standard cubic magnesium ingot of 1m × 1m × 1m. The flexible housing 1 is placed on a base plate, and before the magnesium battery is activated, the drive mechanism, base plate, flexible housing 1 and accessories are first connected. Then, bolts for the standard cubic magnesium ingot are fixed to the fixing bracket, which is attached to the tip of the flexible housing 1. The magnesium ingot is suspended inside the flexible housing 1 by the cooperation of the square sliding grooves, and its four sides are held parallel to the walls of the flexible housing 1. The camera, sensor signal interface and controller MCU are connected by wires, and then, the prepared 10% concentration sodium chloride solution is pumped into the flexible housing 1 via the electrolyte circulation interface 4 using a water pump until the entire magnesium ingot 24 is submerged, the electrochemical reaction starts, and the magnesium battery continues to generate power.

[0035] After the magnesium ingot 24 has undergone an initial reaction period, the camera 26 begins collecting image information, acquiring real-time distance data between the edge of the magnesium ingot 24 and the box wall, and the MCU sets the minimum interval L. min Analyzing L min When the distance exceeds 20 mm, the controller MCU issues a start command to the drive motor, causing it to start rotating in the forward direction, and compresses the wall surface of the flexible housing 1 through the drive mechanism. The drive motor 9 is connected to the rotation sensor and the controller, making it easy to adjust the rotation speed. min If the value is 10 mm or less, the controller MCU sends a signal to suppress the reversal, and the drive mechanism promotes the expansion of the wall surface of the flexible housing 1. When the MCU receives that the viscosity data input from the viscosity sensor exceeds a set viscosity threshold, it commands the water pump 27 between the water tank 22 and the sedimentation tank 23 to pump the suspension in the water tank 22 to the inclined tube sedimentation tank 23 to settle, extract the precipitate from the bottom, and recirculate the supernatant from the upper layer back into the water tank 22.

[0036] As shown in Figure 8, the tracking adjustment system enables the direct use of large-sized standard cubic magnesium ingots in magnesium-air fuel cells, maintaining a relatively constant distance between the battery anode magnesium ingot and the battery cathode air electrode, ensuring that the electrochemical reaction proceeds continuously and stably, and keeping the magnesium-air fuel cell in an efficient power generation state at all times.
