Description

Technical Field

[0001] The invention relates to the technical field of electrolyzers, in particular to an electrolyzer for producing hydrogen by electrolyzing pure water. Background Art

[0002] Water electrolysis refers to the process of pure water being electrolyzed to produce hydrogen and oxygen. Water gains electrons at the cathode and is reduced to form hydrogen, and loses electrons at the anode and is oxidized to form oxygen. The amount of hydrogen produced is about twice that of oxygen. Based on its high energy density and zero emissions, hydrogen has been listed as a potential clean energy fuel. Traditional hydrogen production methods include alkaline aqueous solution electrolysis, proton exchange membrane electrolysis, alkaline membrane electrolysis, etc. The hydrogen production electrolyzer is the place where electrochemical reactions and mass transfer take place during the water electrolysis process. The membrane electrode assembly (MEA) is the core component of the zero-gap electrolyzer and is an important factor in determining the electrolysis performance and stability.

[0003] However, the above technology has the following defects: the anode chamber and cathode chamber are generally separated by a diaphragm in the electrolytic cell. During the electrolysis of water, water-insoluble impurities (calcium hydroxide, ferric hydroxide, ferrous hydroxide, etc.) will be generated in the water body, which will clog the pores on the surface of the diaphragm over time, thereby increasing the energy consumption of the electrolytic cell and reducing its efficiency. To this end, those skilled in the art have proposed an electrolytic cell for electrolyzing pure water to produce hydrogen to solve the above problems. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides an electrolytic cell for electrolyzing pure water to produce hydrogen, which solves the problem that the diaphragm inside the electrolytic cell of the prior art may be blocked, thereby reducing the electrolysis efficiency of the electrolytic cell.

[0007] Preferably, a plurality of knocking plates are fixedly connected to the front side of the electrolytic cell body, the number of the knocking plates is equal to the number of diaphragms, and the installation positions of the knocking plates correspond one-to-one to the positions of the diaphragms, a limiting seat is fixedly connected to the outer middle side of the knocking plate, a knocking rod is connected to the inner side of the limiting seat through a pin shaft, a knocking ball is fixedly connected to the top of the knocking rod, the bottoms of the plurality of knocking rods are connected to each other through a connecting rod, and a support rod is movably connected to the outer side of the connecting rod.

[0008] Preferably, the cooling component includes a fixed cylinder, which is fixedly installed on the outside of the electrolytic cell body, a rubber piston is slidably connected to the inside of the fixed cylinder, a movable rod is fixedly connected to the outside of the rubber piston, the upper surface of the fixed cylinder is connected to a mounting tube, one side of the fixed cylinder is connected to a connecting tube, and one-way valves are installed on the inner sides of the connecting tube and the mounting tube, an air cooler is fixedly connected to the right side of the electrolytic cell body, a connecting tube is connected to the top of the air cooler, one end of the connecting tube is fixedly connected to a cooling tube, and a plurality of nozzles are fixedly connected to the outer surface of the cooling tube at equal intervals.

[0009] Preferably, one end of the connecting pipe is connected to the bottom of the air cooler, and the side of the movable rod away from the rubber piston passes through the outside of the fixed cylinder and is rotatably connected to one end of the right eccentric shaft.

[0010] Preferably, the rear end of the fixing seat is rotatably connected to one end of the left eccentric shaft, and the front end of the fixing seat is fixedly connected to one end of the support rod.

[0011] Preferably, a pole plate is installed inside the electrolytic cell body, and the pole plate is divided into a positive plate and a negative plate. The positive plate is fixedly installed on the inner top wall of the electrolytic cell body, and the negative plate is fixedly installed on the inner bottom wall of the electrolytic cell body. The negative plate is located at a relative position to the positive plate.

[0012] Preferably, the outer side of the second gear is meshingly connected with the outer side of the second rack plate, and the outer side of the second gear is meshingly connected with the outer side of the connecting plate.

[0013] Preferably, one end of the drive shaft is fixedly connected to the outer side of the first gear, and the other end of the drive shaft is movably connected to the inner wall of the electrolytic cell body through a bearing.

[0014] Preferably, two exhaust pipes are fixedly installed on one side of the electrolytic cell body, and a liquid inlet pipe is fixedly connected to the other side of the electrolytic cell body.

[0015] Working principle: To use this device, first add pure water and electrolyte to the main body of the electrolytic cell, then connect the power supply to the main body of the electrolytic cell, and apply a voltage of more than 1.23 volts to allow current to pass through the electrolyte to start the electrolysis reaction, in which water molecules undergo oxidation reaction near the anode to generate oxygen and hydrogen ions, and the hydrogen ions are reduced near the cathode to generate hydrogen, completing the electrolysis process;

[0016] By starting the dual-axis servo motor, the two transmission rods are driven to rotate, which further realizes the coaxial rotation of the circular wheel, so that one end of the eccentric shaft realizes eccentric rotation along the outer surface of the circular wheel. Under the action of the traction force of the eccentric shaft, the movable rod and the first rack plate are driven to realize reciprocating motion. Since the first rack plate is meshed with the first gear, when the first rack plate realizes the forward and backward reciprocating motion, it will drive the first gear to perform synchronous forward and reverse rotation, thus driving the drive shaft to rotate coaxially. The second gear is further driven to rotate coaxially by the rotation of the drive shaft. Since the connecting plate and the second rack plate are meshed with the second gear, as the second gear rotates, the connecting plate and the second rack plate are close to each other, or away from each other, further driving the cleaning plate to move synchronously, and the outer surface of the diaphragm is cleaned by the flexible bristles on the outer surface of the cleaning plate. This can effectively reduce the deposition of impurities in the diaphragm, ensure that the produced hydrogen has a higher purity, and meet the high requirements of industrial and chemical reactions for hydrogen quality;

[0017] In addition, when the first rack plate moves back and forth, it will drive the support rod to move synchronously, and then when the support rod moves, it will drive the connecting rod to move synchronously, further driving the bottom end of the knocking rod to swing. At this time, the top end of the knocking rod, under the action of the pin, continuously knocks the outer surface of the knocking plate through the knocking ball, causing it to vibrate. With the above-mentioned cleaning component, the cleaning effect of the diaphragm can be greatly improved. In this way, the diaphragm can be kept clean, ensuring the efficient movement of ions during the electrolysis process, and significantly increasing the production of hydrogen;

[0018] Finally, with the reciprocating movement of the connecting tube, the rubber piston continuously reciprocates left and right inside the fixed cylinder. When the rubber piston moves to the left along the inner wall of the fixed cylinder, the gas inside the fixed cylinder is discharged into the air cooler through the connecting tube. After cooling, it becomes cold air. Then, the cold air is discharged onto the outer surface of the electrolytic cell body through the cooling tube and the nozzle, so as to cool the electrolytic cell body. In this way, the electrolytic cell body can be within a suitable temperature range, which can ensure the effective migration of ions in the electrolyte and improve the overall efficiency of the electrolytic reaction.

[0019] The present invention provides an electrolytic cell for producing hydrogen by electrolyzing pure water. It has the following beneficial effects:

[0020] 1. The present invention can automatically clean impurities on the outer surface of the diaphragm through the mutual cooperation between the cleaning plate, the connecting plate, the second gear, the second rack plate and other structures, which can effectively reduce the deposition of impurities on the diaphragm, ensure that the produced hydrogen has a higher purity, and meet the high requirements of industrial and chemical reactions on hydrogen quality.

[0021] 2. The present invention uses the supporting rod, connecting rod, limiting seat, knocking plate and other structures to cooperate with each other, so that the knocking plate can be continuously knocked to make the diaphragm vibrate. With the above-mentioned cleaning components, the cleaning effect of the diaphragm can be greatly improved. In this way, the diaphragm can be kept clean, ensuring the efficient movement of ions during the electrolysis process, and significantly increasing the production of hydrogen.

[0022] 3. The present invention can efficiently cool the outer surface of the electrolytic cell body by adding a cooling component, so that the electrolytic cell can be within a suitable temperature range, which can ensure the effective migration of ions in the electrolyte, improve the overall efficiency of the electrolytic reaction, and thus increase the production of hydrogen. At the same time, it can extend the service life of the electrolytic cell and its related components and reduce the replacement and maintenance costs of the equipment.

[0034] Specifically, the electrolytic cell body 1 is the core structure of the entire electrolytic cell, which contains the electrolyte and provides the environment required for electrolysis. The diaphragm 6 is used to effectively separate hydrogen and oxygen to prevent gas mixing. At the same time, the diaphragm 6 is made of corrosion-resistant materials to enhance its durability in the electrolyte. The design of the cleaning plate 801 is to ensure the cleanliness of the diaphragm 6. A plurality of flexible bristles are installed on the outer surface, which can effectively remove the dirt on the surface of the diaphragm 6. The connection plate 802 and the second rack plate 804 are used in combination to realize the movement of the cleaning plate 801. When the connection plate 802 and the second rack plate 804 are close to or away from each other, the cleaning plate 801 will move accordingly. The outer surface of the cleaning plate 801 is equipped with a plurality of flexible bristles, which are designed to gently contact the outer surface of the diaphragm 6, effectively remove impurities and bubbles attached thereto, and ensure the efficient conduct of the electrolysis reaction. The function of the guide rod 7 is to provide a stable moving path for the cleaning plate 801 to ensure that it does not deviate from the predetermined track during the cleaning process. At the same time, the two ends of the guide rod 7 are fixedly connected to the inner wall of the electrolytic cell body 1, thereby enhancing the stability of the structure.

[0035] Please see attached Figure 1 - Attachment Figure 3 A dual-axis servo motor 201 is fixedly installed on the rear side of the electrolytic cell body 1, and the two output ends of the dual-axis servo motor 201 are fixedly connected to a transmission rod 202, and one end of the transmission rod 202 away from the dual-axis servo motor 201 is fixedly connected to a round wheel 203, and the outer eccentric part of the round wheel 203 is rotatably connected to an eccentric shaft 204, and a fixed seat 205 is fixedly connected to the left side of the electrolytic cell body 1, and the top of the fixed seat 205 is slidably connected to a first rack plate 206, and the outer side of the first rack plate 206 is meshed with a first gear 207.

[0036] Specifically, the dual-axis servo motor 201 is an existing mature technical means and is well known to those skilled in the art, so it will not be repeated here. The dual-axis servo motor 201 is started to drive the two transmission rods 202 to rotate, thereby further realizing coaxial rotation of the circular wheel 203, so that one end of the eccentric shaft 204 realizes eccentric rotation along the outer surface of the circular wheel 203, so that under the action of the traction force of the eccentric shaft 204, the transmission rod 202 and the first rack plate 206 are driven to realize reciprocating motion.

[0037] Please see attached Figure 3 and attached Figure 7A plurality of knocking plates 404 are fixedly connected to the front side of the electrolytic cell body 1, the number of the plurality of knocking plates 404 is equal to the number of the diaphragms 6, and the installation positions of the plurality of knocking plates 404 correspond one to one to the positions of the diaphragms 6, a limiting seat 403 is fixedly connected to the outer middle side of the knocking plate 404, a knocking rod 405 is connected to the inner side of the limiting seat 403 through a pin shaft, a knocking ball 406 is fixedly connected to the top of the knocking rod 405, and the bottoms of the plurality of knocking rods 405 are connected to each other through a connecting rod 402, and a support rod 401 is movably connected to the outer side of the connecting rod 402.

[0038] Specifically, when the first rack plate 206 moves back and forth, it will drive the support rod 401 to move synchronously, and then when the support rod 401 moves, it will drive the connecting rod 402 to move synchronously, and further drive the bottom end of the knocking rod 405 to swing. At this time, the top end of the knocking rod 405, under the action of the pin, continuously knocks the outer surface of the knocking plate 404 through the knocking ball 406 to make it vibrate, and with the above-mentioned cleaning component, it can greatly improve the cleaning effect of the diaphragm 6. In this way, the diaphragm 6 can be kept clean, ensuring the efficient movement of ions during the electrolysis process, and significantly increasing the production of hydrogen.

[0039] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 5 The cooling assembly includes a fixed cylinder 301, which is fixedly mounted on the outside of the electrolytic cell body 1, a rubber piston 310 is slidably connected inside the fixed cylinder 301, a movable rod 302 is fixedly connected to the outside of the rubber piston 310, a mounting tube 308 is connected to the upper surface of the fixed cylinder 301, a connecting tube 303 is connected to one side of the fixed cylinder 301, and a check valve 309 is installed on the inner sides of the connecting tube 303 and the mounting tube 308, an air cooler 304 is fixedly connected to the right side of the electrolytic cell body 1, a connecting tube 305 is connected to the top of the air cooler 304, one end of the connecting tube 305 is fixedly connected to a cooling tube 306, and a plurality of nozzles 307 are fixedly connected to the outer surface of the cooling tube 306 at equal intervals. One end of the connecting tube 303 is connected to the bottom of the air cooler 304, and the side of the movable rod 302 away from the rubber piston 310 passes through the outside of the fixed cylinder 301 and is rotatably connected to one end of the right eccentric shaft 204.

[0040] Specifically, the fixed cylinder 301 has good sealing performance to ensure that the internal gas will not leak, the rubber piston 310 has good elasticity, and the rubber piston 310 is slidably connected in the fixed cylinder 301, responsible for promoting the flow of gas. When the piston moves in the fixed cylinder 301, it can effectively compress or expand the gas, thereby realizing the discharge and intake of the gas. The one-way valve 309 is installed in the connecting pipe 303 and the mounting pipe 308 to ensure that the gas only flows in a predetermined direction to avoid backflow. The function of the air cooler 304 is to exchange heat with the external environment, reduce the temperature of the incoming gas, and send cold air into the electrolytic cell body 1. The cooling pipe 306 is responsible for guiding the gas after cooling treatment to be discharged to the electrolytic cell 1. The nozzles 307 are evenly distributed on the outside of the cooling pipe 306 to evenly spray cold air on the electrolytic cell body 1 to improve the cooling effect. Keeping the electrolyzer within a suitable temperature range can ensure effective migration of ions in the electrolyte, improve the overall efficiency of the electrolysis reaction, and thereby increase hydrogen production. It can also extend the service life of the electrolyzer and its related components, and reduce equipment replacement and maintenance costs.

[0041] Please see attached Figure 1 and attached Figure 6 The rear end of the first rack plate 206 is rotatably connected to one end of the left eccentric shaft 204 , and the front end of the first rack plate 206 is fixedly connected to one end of the support rod 401 .

[0042] Specifically, the swing of the eccentric shaft 204 further drives the first rack plate 206 to move, and further drives the support rod 401 to move synchronously.

[0043] Please refer to Appendix 3. The inside of the electrolytic cell body 1 is equipped with a pole plate 5. The pole plate 5 is divided into a positive plate and a negative plate. The positive plate is fixedly mounted on the inner top wall of the electrolytic cell body 1, and the negative plate is fixedly mounted on the inner bottom wall of the electrolytic cell body 1. The negative plate is located at a relative position to the positive plate.

[0044] Specifically, the main function of the electrolyzer body 1 is to provide a closed environment for the reaction of electrolyzing water to produce hydrogen. Inside the electrolyzer body, a plate 5 is installed, and the plate 5 is divided into a positive plate and a negative plate.

[0045] The anode plate is fixedly mounted on the inner top wall of the electrolytic cell body 1, located above the cell body. This ensures that the anode plate can effectively contact the electrolyte during the electrolysis process to promote the generation of oxygen. The function of the anode plate is: in the electrolysis reaction, the anode plate is responsible for extracting electrons from water molecules, promoting the release of oxygen, and then the generated oxygen escapes from the surface of the anode plate and is discharged through the exhaust pipe 10.

[0046] The cathode plate is fixedly mounted on the inner bottom wall of the electrolytic cell body 1, and is located at the opposite position of the anode plate. This layout ensures an effective electric field between the anode plate and the cathode plate, and enhances the electrolysis efficiency. The cathode plate is used for reduction reaction. During the electrolysis process, hydrogen ions obtain electrons on the cathode plate surface to generate hydrogen. The generated hydrogen escapes through the cathode plate surface and is exported to the collection device.

[0047] Please see attached Figure 1 , Attachment Figure 2 , Attachment Figure 7 and attached Figure 8 The outer side of the second gear 803 is meshed with the outer side of the second rack plate 804, and the outer side of the second gear 803 is meshed with the outer side of the connecting plate 802. One end of the drive shaft 805 is fixedly connected to the outer side of the first gear 207, and the other end of the drive shaft 805 is movably connected to the inner wall of the electrolytic cell body 1 through a bearing. Two exhaust pipes 10 are fixedly installed on one side of the electrolytic cell body 1, and a liquid inlet pipe 9 is fixedly connected to the other side of the electrolytic cell body 1.

[0048] Specifically, the function of the exhaust pipe 10 is to discharge the hydrogen and oxygen inside the electrolytic cell body 1, and the function of the liquid inlet pipe 9 is to pour the electrolyte into the electrolytic cell body 1. Since the connecting plate 802 and the second rack plate 804 are meshed with the second gear 803, as the second gear 803 rotates, the connecting plate 802 and the second rack plate 804 approach each other, or move away from each other, further driving the cleaning plate 801 to move synchronously.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
