Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen production by electrolysis, and specifically to a constant-temperature and high-efficiency hydrogen electrolysis preparation device. Background Art

[0002] Hydrogen electrolysis is a process of producing hydrogen by electrolyzing water. It uses electrical energy to drive the decomposition of water molecules into hydrogen and oxygen. Electrolysis is a process in which an electric current passes through an electrolyte solution or a molten substance to cause the electrolyte to undergo a decomposition reaction..

[0003] The prior art discloses a Chinese patent with the application number CN202311465140.1, a hydrogen electrolysis manufacturing device, and discloses that hydrogen and oxygen are electrolyzed separately through two electrolysis chambers, and a crushing wheel crushes large-sized hydrogen compounds so that the hydrogen compounds can be fully absorbed by tap water.

[0004] Although the above device can complete the production of hydrogen from water and oxygen, there are still some problems: 1. When electrolyzing hydrogen, the internal temperature will rise due to the reduction of the electrolyte. If the temperature is not lowered, the concentration of the electrolyte will change, affecting electrolysis. Therefore, it is impossible to cool down and recover the high temperature during electrolysis, and it is impossible to isolate hydrogen and oxygen in the gas during temperature discharge, resulting in the discharge of hydrogen and oxygen; 2. When electrolyzing hydrogen, it is necessary to keep the space airtight to reduce the influence of external air on the purity of hydrogen. Therefore, it is impossible to supplement additives to the anode and cathode in the electrolytic cell during the electrolysis of hydrogen, which brings inconvenience to hydrogen production by electrolysis.

[0015] A copper mesh is fixedly installed on the lower end surface of the telescopic pipe. When the pure water in the electrolytic cell is electrolyzed and the temperature becomes too high due to the reduction of the water volume, when the hot air inside is discharged, the copper mesh can block oxygen and hydrogen when the hot air is discharged.

[0016] Advantages of the present invention: 1. The present invention drives the shaft rod to rotate by starting the motor. When the shaft rod rotates, it synchronously drives the middle ring to rotate. When the middle ring rotates, it synchronously drives the carriage to move up and down. When the carriage slides downward, it drives the vertical rod to move downward, so that the rubber plug removes the blockage of the blanking port. At this time, the additive in the collection rack falls into the receiving hopper, and then is respectively put into the anode and cathode in the electrolytic cell through the feeding pipe. And as the weight of the additive in the collection rack decreases, under the action of the spring, and due to the impact when the rubber plug moves up and down, it can also make the additive in the collection rack vibrate, thus avoiding the situation that the additive agglomerates and cannot fall. Since the receiving hopper is in a funnel shape, when the vertical rod slides up and down inside it, the receiving hopper can fully receive the additive falling from the blanking port. Compared with the existing device, the present invention can put additives inside in a space-closed state when the electrolytic cell is working during electrolytic hydrogen production, and the feeding operation can be completed without opening the electrolytic cell, so that the feeding of additives is more convenient and flexible.

[0017] 2. Through the setting of the belt pulley and the belt, the present invention can synchronously drive the middle rod to rotate. When the middle rod rotates, it can stir and displace the additives stored between multiple partitions. Through stirring, the additives can be kept dry, avoiding adhesion during storage. By opening the conveying pipe, the additives between two partitions can be replenished into the collection rack, and the quantity of additives between each two partitions is the same, so that the amount of additives added to the collection rack each time is the same. Compared with the existing device, the present invention can automatically put additives during water-oxygen electrolysis without manual operation for additive feeding, and can vibrate the additives during additive feeding to avoid adhesion of the additives.

[0018] 3. By starting the electric push rod, the driven bevel gear at its end meshes with the driving bevel gear. When the shaft rod rotates, it can also drive the driving bevel gear to rotate. When stirring the additives in the electrolytic cell, when the driving bevel gear rotates, it synchronously drives the driven bevel gear to rotate through meshing. When the electric push rod rotates, it can synchronously drive two stirring blades to rotate through the sprocket and the chain. When the two stirring blades rotate, they can fully stir the additives in the electrolytic cell. Through stirring, the uniform distribution of the electrolytic cell can be promoted, and at the same time, it can prevent the precipitation and accumulation of sediment and structures in the electrolyte inside the electrolytic cell, keeping its interior clean and unobstructed. Compared with other electrolysis devices, the present invention can utilize the feeding of additives to synchronously stir the electrolyte in the electrolytic cell without additional drive, saving energy.

[0019] 4. When the piston rod compresses downward in the air cylinder in the present invention, the air cylinder injects external gas into the upper layer tube at this time. Subsequently, the external gas is transmitted to the lower layer tube through the U-shaped tube and finally placed below the two sealing plates in the electrolytic cell through the telescopic tube. When the piston rod sucks upward in the air cylinder, the high temperature below the two sealing plates enters the lower layer tube through the telescopic tube, and the hot air in the lower layer tube enters the upper layer tube through the U-shaped tube. Since a one-way valve is provided at the connection between the air cylinder and the upper layer tube, when the piston rod sucks upward in the air cylinder, the hot air in the upper layer tube will not enter the air cylinder. The exhausted hot air is finally recycled to the recycling box through the recycling tube for secondary use. Through the setting of the copper mesh, when the temperature in the electrolytic cell is too high and its temperature is discharged to reduce the temperature, the copper mesh can effectively block oxygen and hydrogen in the electrolytic cell, avoiding the emission of hydrogen and oxygen generated during water electrolysis for hydrogen production into the recycling box. Compared with the existing device, the present invention can cool the internal temperature of the electrolytic cell immediately when the temperature of the electrolytic cell is too high during water electrolysis for hydrogen production, and the copper mesh can block oxygen and hydrogen in the exhausted high temperature, and can also recycle the exhausted high temperature for secondary use.

[0020] 5. While the present invention cools down by compressing gas in the air cylinder by the piston rod into the electrolytic cell, the compressed gas impacts the sealing plug through the vertical tube. At this time, the moving plate drives the sealing plug to move downward, and at this time, the moving plate moves downward to press the button. After the button is pressed, it controls the water tank to transport the pure water inside it to below the two sealing plates through the water supply pipe. It should be noted that the spaces formed by the two sealing plates and the electrolytic cell are the cathode and the anode respectively. Oxygen is generated at the anode and hydrogen is generated at the cathode. The oxygen and hydrogen generated at the anode and the cathode respectively are discharged and collected through the corresponding collecting tubes communicating with their interiors. Compared with the existing device, the present invention can inject external gas and discharge internal gas when the temperature in the electrolytic cell is too high, realizing heat exchange and cooling while also supplementing the electrolyte inside, and further assisting in cooling the electrolytic cell by supplementing the electrolyte.

[0021] 6. The present invention can realize water electrolysis for hydrogen production through the setting of the electrolytic cell. By setting two diaphragms, the purity of hydrogen during electrolysis for hydrogen production can be improved, the internal resistance of the electrolytic cell can be reduced, thus ensuring the safe operation of the equipment. Through the setting of the feeding unit, additives can be put in, and the setting of the supplement unit can ensure the quantitative supplement of additives each time. Through the setting of the stirring blades, the additives can be fully stirred after being put in, so that they are evenly distributed in the anode space and the cathode space in the electrolytic cell, improving the electrolysis efficiency and hydrogen production, and maintaining the stability of the electrolysis process. The setting of the display can directly observe the temperature during water electrolysis in the electrolytic cell, so as to immediately supplement the water volume in the electrolytic cell, avoiding the decomposition of the electrolyte or the inactivation of the electrode material due to the excessive temperature in the electrolytic cell caused by the reduction of the water volume, affecting the stability and service life of the electrolytic cell.

Detailed Embodiments

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0025] As shown in the attached Figure 1-8 figures, a constant-temperature and high-efficiency hydrogen electrolysis preparation device includes an electrolytic cell 1. An installation frame 10 is fixedly installed in the middle of the electrolytic cell 1. Diaphragms 11 are provided on both sides of the installation frame 10. The diaphragms 11 divide the electrolytic cell 1 into an anode and a cathode. A sealing plate 101 is provided on the top of the installation frame 10. Stirring blades 12 rotatably connected to the electrolytic cell 1 are provided on both sides of the installation frame 10. Two symmetrically arranged collecting pipes 13 are fixedly installed on one side of the electrolytic cell 1. The two collecting pipes 13 are respectively used to discharge hydrogen and oxygen during water and oxygen electrolysis for collection. A feeding unit is fixedly installed on the outside of one side of the electrolytic cell 1, and a replenishing unit is fixedly installed on the outside of the feeding unit. A temperature reduction unit is fixedly installed in the inner cavity of the electrolytic cell 1. Recovery boxes 17 are fixedly installed on the lower parts of both sides of the electrolytic cell 1. A plurality of recovery pipes 171 are commonly installed between the recovery boxes 17 and the temperature reduction unit. A display 18 for real-time monitoring of the temperature inside the electrolytic cell 1 is fixedly installed in the middle of one side of the electrolytic cell 1.

[0026] The setting of the electrolytic cell 1 can realize hydrogen production by electrolyzing water. Since there are two diaphragms 11, the purity of hydrogen during electrolytic hydrogen production can be improved, and the internal resistance of the electrolytic cell can be reduced, thereby ensuring the safe operation of the equipment. The setting of the feeding unit can put additives. The setting of the replenishing unit can ensure the quantitative replenishment of additives each time. The setting of the stirring blades 12 can fully stir the additives after being put in, so that they are evenly distributed in the anode space and the cathode space in the electrolytic cell 1, improving the electrolysis efficiency and hydrogen production, and maintaining the stability of the electrolysis process. The setting of the display 18 can directly observe the temperature during water and oxygen electrolysis in the electrolytic cell 1, so as to immediately supplement the water volume in the electrolytic cell 1 to avoid the electrolyte decomposition or the loss of activity of the electrode material due to the excessive temperature in the electrolytic cell 1 caused by the reduction of the water volume, affecting the stability and service life of the electrolytic cell 1.

[0027] As shown in the attached Figure 6 、 7As shown in the figure, the feeding unit includes a side box 20. A shaft rod 21 is rotatably installed in the middle of the side box 20 by a motor. An outer sleeve 22 is rotatably installed outside the shaft rod 21. A collecting frame 23 is slidably installed up and down outside the outer sleeve 22. The collecting frame 23 is slidably connected to the side box 20. A blanking port 230 is opened on one side of the lower end surface of the collecting frame 23. A circular plate 24 fixed to the shaft rod 21 is provided below the collecting frame 23. A plurality of circumferentially arranged springs are fixedly installed on the upper end surface of the circular plate 24. A thread is provided on the outer edge of the shaft rod 21 below the circular plate 24. A middle ring 25 is threadedly and rotatably installed outside the thread. A sliding frame 26 is rotatably installed on the outer edge of the middle ring 25. One side of the sliding frame 26 is slidably connected to the side box 20 up and down.

[0028] When the motor is started, the shaft rod 21 is driven to rotate. When the shaft rod 21 rotates, the middle ring 25 is synchronously driven to rotate. When the middle ring 25 rotates, the sliding frame 26 is synchronously driven to lift and lower. When the sliding frame 26 slides downward, the vertical rod 250 is driven to move downward, so that the rubber plug 251 removes the blockage of the blanking port 230. At this time, the additive in the collecting frame 23 falls into the receiving hopper 28, and then is respectively put into the anode and cathode in the electrolytic cell 1 through the feeding pipe 281. And as the weight of the additive in the collecting frame 23 decreases, under the action of the spring, and the impact when the rubber plug 251 moves up and down, the additive in the collecting frame 23 can also be shaken, thereby avoiding the situation that the additive agglomerates and cannot fall. Since the receiving hopper 28 is in a funnel shape, when the vertical rod 250 slides up and down inside it, the receiving hopper 28 can fully receive the additive falling from the blanking port 230. Compared with the existing device, the present invention can put the additive inside in a space-closed state when the electrolytic cell 1 is working during electrolytic hydrogen production, and the feeding operation can be completed without opening the electrolytic cell 1, so that the feeding of the additive is more convenient and flexible.

[0029] A vertical rod 250 is fixedly installed on one side of the upper end surface of the sliding frame 26. A rubber plug 251 for blocking the blanking port 230 is fixedly installed at the top of the vertical rod 250. A support plate 27 fixed to the side box 20 is provided on one side of the shaft rod 21. A receiving hopper 28 slidably located outside the vertical rod 250 is provided in the middle of the support plate 27. A feeding pipe 281 is fixedly installed on one side of the receiving hopper 28. The side of the feeding pipe 281 away from the receiving hopper 28 is of a two-section structure and respectively penetrates through two sealing plates 101.

[0030] As shown in the Figure 8 figure, the replenishing unit includes a fixed frame 30. A storage cylinder 31 is fixedly installed in the middle of the fixed frame 30. A middle rod 32 is rotatably installed in the middle of the storage cylinder 31. A plurality of circumferentially arranged partition plates 33 are fixedly installed on the upper side of the middle rod 32. A conveying pipe 34 penetrating through the side box 20 is fixedly installed on one side of the storage cylinder 31. One end of the conveying pipe 34 is telescopically arranged and communicated with the collecting frame 23.

[0031] When the motor is turned on to drive the shaft 21 to rotate, the middle rod 32 can be synchronously driven through the settings of the belt pulley 320 and the belt 321. When the middle rod 32 rotates, it can stir and displace the additives stored between multiple partitions 33. Through the stirring, the additives can be kept dry to avoid bonding during storage. By opening the conveying pipe 34, the additives between two partitions 33 can be supplemented into the collection rack 23, and the quantity of additives between every two partitions 33 is the same, so that the amount of additives added to the collection rack 23 each time is the same. Compared with the existing devices, the present invention can automatically put additives during the electrolysis of water and oxygen without manual operation, and can shake the additives during the addition to avoid bonding of the additives.

[0032] A belt pulley 320 is fixedly installed at the bottom of the middle rod 32 and on the shaft 21, and a belt 321 is commonly installed between the belt pulleys 320. An electric push rod 16 rotatably connected to the outer wall of the electrolytic cell 1 is provided between two stirring blades 12. Sprockets 14 are installed on both the electric push rod 16 and the two stirring blades 12, and a chain 15 is installed between the sprockets 14. A driven bevel gear 161 is fixedly installed at the telescopic end of the electric push rod 16, and a driving bevel gear 210 fixed to the shaft 21 is provided on one side of the driven bevel gear 161.

[0033] When the electric push rod 16 is turned on to make the driven bevel gear 161 at its end mesh with the driving bevel gear 210, the shaft 21 can drive the driving bevel gear 210 to rotate while rotating. When stirring the additives in the electrolytic cell 1, when the driving bevel gear 210 rotates, it synchronously drives the driven bevel gear 161 to rotate through meshing. When the electric push rod 16 rotates, it can synchronously drive the two stirring blades 12 to rotate through the sprockets 14 and the chain 15. When the two stirring blades 12 rotate, they can fully stir the additives in the electrolytic cell 1. Through the stirring, the uniform distribution of the electrolytic cell 1 can be promoted, and at the same time, the precipitation and accumulation of sediment and structures in the electrolyte in the electrolytic cell 1 can be prevented, keeping its interior clean and unobstructed. Compared with other electrolysis devices, the present invention can utilize the addition of additives to synchronously stir the electrolyte in the electrolytic cell 1 without additional drive, saving energy.

[0034] As shown in the Figure 3 accompanying drawings, the cooling unit includes an upper layer pipe 40. A lower layer pipe 41 fixed to the inner wall of the electrolytic cell 1 is provided below the upper layer pipe 40. A plurality of U-shaped pipes 42 arranged at equal intervals are commonly installed between the upper layer pipe 40 and the lower layer pipe 41. A plurality of groups of telescopic pipes 43 are fixedly installed on both sides of the lower end face of the lower layer pipe 41. A copper mesh 44 is fixedly installed at the lower end face of the telescopic pipes 43. Two groups of telescopic pipes 43 respectively penetrate through the sealing plates 101 below them, and the telescopic pipe 43 placed in the cathode of the electrolytic cell 1 is higher than the other group of telescopic pipes 43 placed in the anode.

[0035] Since the electrolyte is electrolyzed in the electrolytic cell 1, the electrolyte will gradually decrease. At this time, the temperature water in the electrolytic cell 1 gradually rises with the evaporation of the electrolyte. If it is not cooled down, the excessive temperature will carry away a large amount of lye and water vapor, increasing the risk of equipment corrosion. At the same time, it may also cause changes in the electrolyte concentration and affect the electrolysis efficiency. Therefore, it is necessary to reduce the temperature in the electrolytic cell 1. At this time, the motor is turned on. When the motor is turned on, it drives the cam 490 to rotate. When the cam 490 rotates, it synchronously drives the round rod 491 to rotate. When the round rod 491 rotates, it drives the piston rod 46 to compress in the air cylinder 45. When the piston rod 46 compresses downward in the air cylinder 45, the air cylinder 45 injects external gas into the upper layer pipe 40 at this time. Subsequently, the external gas is transmitted to the lower layer pipe 41 through the U-shaped pipe 42 and finally placed below the two sealing plates 101 in the electrolytic cell 1 through the telescopic pipe 43. When the piston rod 46 sucks upward in the air cylinder 45, the high temperature below the two sealing plates 101 enters the lower layer pipe 41 through the telescopic pipe 43. The hot gas in the lower layer pipe 41 enters the upper layer pipe 40 through the U-shaped pipe 42. Since a one-way valve is provided at the connection between the air cylinder 45 and the upper layer pipe 40, when the piston rod 46 sucks upward in the air cylinder 45, the hot gas in the upper layer pipe 40 will not enter the air cylinder 45. The exhausted hot gas is finally recovered into the recovery box 17 through the recovery pipe 171 for secondary use. Through the setting of the copper mesh 44, when the temperature in the electrolytic cell 1 is too high and its temperature is discharged to reduce the temperature, it can effectively block the oxygen and hydrogen in the electrolytic cell 1, avoiding the hydrogen and oxygen generated during the electrolysis of water and oxygen to be discharged into the recovery box 17. Compared with the existing device, the present invention can cool the internal temperature of the electrolytic cell 1 immediately when the temperature of the electrolytic cell 1 is too high during the electrolysis of water and oxygen to produce hydrogen, and use the setting of the copper mesh 44 to resist the oxygen and hydrogen in the discharged high temperature, and can also recover the discharged high temperature for secondary use.

[0036] A cylinder 45 communicating with the upper layer pipe 40 is fixedly installed on one side of the electrolytic cell 1. A piston rod 46 is slidably installed in the cylinder 45. One end of the piston rod 46 is fixedly installed with an end plate 47. An arc groove 48 is opened in the middle of the end plate 47. Above the end plate 47, there is a fixing plate 49 fixed to the electrolytic cell 1. One side of the lower end surface of the fixing plate 49 is rotatably installed with a cam 490 through a motor. One side of the lower end surface of the cam 490 is fixedly installed with a round rod 491, and the round rod 491 is placed in the arc groove 48.

[0037] As attached Figure 1 、 8As shown in the figure, a water tank 50 fixed to the electrolytic cell 1 is provided below the air cylinder 45. A middle frame 51 is fixedly installed above the water tank 50. A vertical pipe 52 is commonly connected between the middle frame 51 and the air cylinder 45. A moving plate 53 is slidably installed in the middle of the middle frame 51. A spring is commonly installed between the lower end surface of the moving plate 53 and the middle frame 51. A sealing plug 54 for blocking the vertical pipe 52 is fixedly installed on the upper end surface of the moving plate 53.

[0038] When the piston rod 46 compresses the gas in the air cylinder 45 and injects it into the electrolytic cell 1 to achieve temperature reduction, the compressed gas impacts the sealing plug 54 through the vertical pipe 52. At this time, the moving plate 53 drives the sealing plug 54 to move downward. At this time, the moving plate 53 moves downward and presses the button 501. After the button 501 is pressed, it controls the water tank 50 to transport the pure water inside it to the lower part of the two sealing plates 101 through the water supply pipe 502. It should be noted that the spaces formed by the two sealing plates 101 and the electrolytic cell 1 are the cathode and the anode respectively. Oxygen is generated at the anode and hydrogen is generated at the cathode. The oxygen and hydrogen generated at the anode and the cathode respectively are discharged and collected through the corresponding collecting pipes 13 communicating with their interiors. Compared with the existing device, the present invention can inject external gas and discharge internal gas when the temperature in the electrolytic cell 1 is too high, so as to achieve heat exchange and temperature reduction, and at the same time, it can supplement the electrolyte inside it. By supplementing the electrolyte, it further assists in cooling the electrolytic cell 1.

[0039] Below the moving plate 53, there is a button 501 for controlling the water tank 50 to inject pure water into the cathode and anode in the electrolytic cell 1. A water supply pipe 502 is fixedly installed on the lower end surface of the water tank 50. The end of the water supply pipe 502 away from the water tank 50 has a two-section structure and its two ends respectively penetrate through the two sealing plates 101.

[0040] A copper mesh 44 is fixedly installed on the lower end surface of the telescopic pipe 43. When the pure water in the electrolytic cell 1 is electrolyzed and the temperature becomes too high due to the decrease in water volume, when discharging the hot air inside it, the copper mesh 44 can block oxygen and hydrogen when discharging the hot air.

[0041] In use, pure water is pre-injected into the electrolytic cell 1 for electrolytic hydrogen production. And two collecting tubes 13 are manually pre-connected to an external collecting device in advance to separately collect the oxygen and hydrogen generated during the electrolytic water and oxygen hydrogen production. The electrolytic cell 1 is turned on to realize the electrolytic water and oxygen hydrogen production. This is prior art and will not be elaborated here. The motor is turned on to drive the shaft rod 21 to rotate. When the shaft rod 21 rotates, it synchronously drives the middle ring 25 to rotate. When the middle ring 25 rotates, it synchronously drives the carriage 26 to move up and down. When the carriage 26 slides downward, it drives the vertical rod 250 to move downward, so that the rubber plug 251 cancels the blockage of the discharge port 230. At this time, the additive in the collecting rack 23 falls into the receiving hopper 28, and then is respectively put into the anode and cathode in the electrolytic cell 1 through the feeding pipe 281. And as the weight of the additive in the collecting rack 23 decreases, under the action of the spring, and the impact when the rubber plug 251 moves up and down, it can also make the additive in the collecting rack 23 vibrate, thereby avoiding the situation where the additive agglomerates and cannot fall. Since the receiving hopper 28 is in a funnel shape, when the vertical rod 250 slides up and down inside it, the receiving hopper 28 can fully receive the additive falling from the discharge port 230. Compared with the existing device, the present invention can, during the electrolytic hydrogen production, when the electrolytic cell 1 is working, put the additive inside in a closed space state without opening the electrolytic cell 1 to complete the feeding operation, so that the feeding of the additive is more convenient and flexible; When the motor starts and drives the shaft rod 21 to rotate, the middle rod 32 can be synchronously driven through the settings of the belt pulley 320 and the belt 321. When the middle rod 32 rotates, the additives stored between multiple partitions 33 can be transposed and agitated. Through agitation, the additives can be kept dry, avoiding adhesion of the additives during storage. By opening the delivery pipe 34, the additives between two partitions 33 can be supplemented into the collection rack 23, and the quantity of additives between every two partitions 33 is the same, enabling the same amount of additives to be added to the collection rack 23 each time. Compared with the existing devices, the present invention can automatically dispense additives during the electrolysis of water and oxygen, without manual dispensing of additives, and can jitter the additives during the dispensing process to avoid adhesion of the additives. When the electric push rod 16 is opened, the driven bevel gear 161 at its end meshes with the driving bevel gear 210. While the shaft rod 21 rotates, it can also drive the driving bevel gear 210 to rotate. When stirring the additives in the electrolytic cell 1, when the driving bevel gear 210 rotates, it synchronously drives the driven bevel gear 161 to rotate through meshing. When the electric push rod 16 rotates, it can synchronously drive the two stirring blades 12 to rotate through the sprocket 14 and the chain 15. When the two stirring blades 12 rotate, they can fully stir the additives in the electrolytic cell 1. Through stirring, the uniform distribution of the electrolytic cell 1 can be promoted, and at the same time, the precipitation and structures in the electrolyte can be prevented from accumulating in the electrolytic cell 1, keeping its interior clean and unobstructed. Compared with other electrolysis devices, the present invention can utilize the dispensing of additives to synchronously stir the electrolyte in the electrolytic cell 1 without additional drive, saving energy; Since the electrolyte is electrolyzed in the electrolytic cell 1, the electrolyte will gradually decrease. At this time, the temperature of the water in the electrolytic cell 1 gradually rises with the evaporation of the electrolyte. If the temperature is not lowered, the excessive temperature will carry away a large amount of alkali liquid and water vapor, increasing the risk of equipment corrosion. At the same time, it may also cause changes in the electrolyte concentration, affecting the electrolysis efficiency. Therefore, it is necessary to lower the temperature in the electrolytic cell 1. At this time, the motor is turned on. When the motor is turned on, it drives the cam 490 to rotate. When the cam 490 rotates, it synchronously drives the round rod 491 to rotate. When the round rod 491 rotates, it drives the piston rod 46 to compress in the air cylinder 45. When the piston rod 46 compresses downward in the air cylinder 45, the air cylinder 45 injects external gas into the upper layer pipe 40 at this time. Subsequently, the external gas is transmitted to the lower layer pipe 41 through the U-shaped pipe 42 and finally placed below the two sealing plates 101 in the electrolytic cell 1 through the telescopic pipe 43. When the piston rod 46 sucks upward in the air cylinder 45, the high temperature below the two sealing plates 101 enters the lower layer pipe 41 through the telescopic pipe 43. The hot gas in the lower layer pipe 41 enters the upper layer pipe 40 through the U-shaped pipe 42. Since a one-way valve is provided at the connection between the air cylinder 45 and the upper layer pipe 40, when the piston rod 46 sucks upward in the air cylinder 45, the hot gas in the upper layer pipe 40 will not enter the air cylinder 45. The exhausted hot gas is finally recovered into the recovery box 17 through the recovery pipe 171 for secondary use. Through the setting of the copper mesh 44, when the temperature in the electrolytic cell 1 is too high and its temperature is discharged to lower the temperature, the oxygen and hydrogen in the electrolytic cell 1 can be effectively blocked, preventing the hydrogen and oxygen generated during the electrolysis of water and oxygen to produce hydrogen from being discharged into the recovery box 17. Compared with the existing device, the present invention can cool the internal temperature of the electrolytic cell 1 immediately when the temperature of the electrolytic cell 1 is too high during the electrolysis of water and oxygen to produce hydrogen, and use the setting of the copper mesh 44 to block the oxygen and hydrogen in the discharged high temperature, and can also recover the discharged high temperature for secondary use; When the piston rod 46 compresses the gas in the air cylinder 45 to cool the electrolytic cell 1, the compressed gas impacts the sealing plug 54 through the vertical pipe 52. At this time, the moving plate 53 drives the sealing plug 54 to move downward. At this time, the moving plate 53 moves downward to press the button 501. At this time, after the button 501 is pressed, it controls the water tank 50 to transport the pure water inside it to the lower part of the two sealing plates 101 through the water supply pipe 502. It should be noted that the spaces formed by the two sealing plates 101 and the electrolytic cell 1 are the cathode and the anode respectively. Oxygen is generated at the anode and hydrogen is generated at the cathode. The oxygen and hydrogen generated at the anode and the cathode respectively are discharged and collected through the corresponding collection pipes 13 communicating with their interiors. Compared with the existing device, the present invention can inject external gas and discharge internal gas when the temperature in the electrolytic cell 1 is too high, realizing heat exchange and cooling, and can also supplement the electrolyte inside it, and further assist in cooling the electrolytic cell 1 by supplementing the electrolyte.
