Description

Technical Field

[0001] This invention belongs to the technical field of hydrogen production and relates to a generator for hydrogen production. Background Technology

[0002] With the development of clean energy technologies, hydrogen has received widespread attention as a highly efficient and environmentally friendly energy carrier. To meet the hydrogen demands of various applications, hydrogen generators have become important hydrogen production devices due to their convenience and flexibility. Hydrogen generators typically employ water electrolysis technology, which is based on the principle that water molecules decompose into hydrogen and oxygen under the influence of electrical energy.

[0003] Currently, although commercially available electrolyte hydrogen generators use electrolysis to produce hydrogen, which is highly efficient, in actual operation, as the electrolysis process continues, the solution gradually decreases, requiring replenishment of the electrolyte. Otherwise, when the electrolyte level is close to the minimum level of the electrolysis device, the equipment is prone to damage due to lack of electrolyte. The existing method requires manual replenishment of the electrolyte, which is a rather cumbersome process. Summary of the Invention

[0004] In view of this, the present invention provides a generator for hydrogen production.

[0005] The technical solution is as follows: A generator for hydrogen production includes a manufacturing chamber, a swing plate, an electrolytic tank, a connecting pipe, a diaphragm, an oxygen discharge pipe, a hydrogen discharge pipe, an electrolysis structure, a gas storage mechanism, and a liquid addition mechanism. The manufacturing chamber is rotatably connected to the swing plate. Electrolytic tanks are connected to both sides of the manufacturing chamber. A connecting pipe connects the lower sides of the two electrolytic tanks. Two diaphragms are installed inside the connecting pipe. An oxygen discharge pipe is connected to the top of one electrolytic tank, extending out of the manufacturing chamber. Hydrogen discharge pipes are connected to both sides of the top of the other electrolytic tank. The manufacturing chamber contains an electrolysis structure for electrolyzing a solution, a gas storage mechanism for storing hydrogen, and a liquid addition mechanism for adding solution.

[0006] Furthermore, it is particularly preferred that the electrolysis structure includes a battery, conductive pillars, electrolytic plates, and conductive wires. The battery is connected to the upper part of the manufacturing box, and a conductive pillar is connected to the middle of the inside of the electrolysis tank. One of the conductive pillars is connected to the positive electrode of the battery with a conductive wire, and the other conductive pillar is also connected to the negative electrode of the battery with a conductive wire. Multiple electrolytic plates are evenly spaced on the conductive pillar.

[0007] Furthermore, it is particularly preferred that the gas storage mechanism includes an exhaust box, a baffle, an exhaust pipe, and a valve. The exhaust box is connected to the manufacturing box body, the bottom of the exhaust box is connected to the hydrogen exhaust pipe, the upper part of the exhaust box is connected to the baffle, and both sides of the baffle are connected to the exhaust pipe. A valve is installed at the exhaust pipe.

[0008] Furthermore, it is particularly preferred that the liquid addition mechanism includes a liquid storage tank, a liquid injection pipe, a water pump, a liquid inlet pipe, a cylindrical stopper, and a control component. The liquid storage tank is connected to the upper part of the manufacturing box. The bottom of the liquid storage tank is connected to both electrolytic tanks by liquid injection pipes. A water pump is installed at the bottom of the liquid storage tank. The outlet end of the water pump is connected to the liquid injection pipe, and the inlet end of the water pump is connected to the inside of the liquid storage tank. The top of the liquid storage tank is connected to the liquid inlet pipe, and a cylindrical stopper is inserted into the liquid inlet pipe.

[0009] Furthermore, it is particularly preferred that the control component includes a guide sleeve, a float block, a start button, and a stop button, wherein the guide sleeve is connected to the upper part of an electrolysis tank and communicates with the interior of the electrolysis tank, a float block is slidably connected inside the guide sleeve, a stop button is connected to the top of the float block, and a start button is connected to the lower part of the guide sleeve. Both the start button and the stop button are electrically connected to the water pump.

[0010] Furthermore, it is particularly preferred that a cleaning mechanism is also included, which includes a drive motor, a drive gear, a transmission gear, an internal gear ring, scrapers, connecting plates, and pinions. The drive motor is installed in the middle of the upper part of the manufacturing box, and the drive gear is connected to the output shaft of the drive motor. Transmission gears are rotatably connected to the top of both electrolytic tanks, and the drive gear meshes with the transmission gear. The lower part of the transmission gear extends into the electrolytic tank and is connected to a pinion. An internal gear ring is rotatably connected to the upper part of the electrolytic tank, and the internal gear ring meshes with the pinion. Connecting plates are connected to both sides of the bottom of the internal gear ring. Multiple sets of scrapers are evenly spaced on the connecting plates, and each set of scrapers has two scrapers and is sleeved on the upper and lower sides of the electrolytic plate.

[0011] Furthermore, it is particularly preferred that the device also includes a drainage mechanism, which includes a discharge cylinder, a liquid guide pipe, a second valve, a turbine, and bottom scrapers. The discharge cylinder is connected to the middle of the bottom of both electrolytic tanks. The bottom of the discharge cylinder is connected to a liquid guide pipe. The rear sections of the two liquid guide pipes are connected to each other and their ends extend out of the manufacturing box. The second valve is provided on the liquid guide pipe.

[0012] Furthermore, it is particularly preferred that the gas exhaust box also includes a partition and a molecular sieve, with two partitions connected to the lower part of the exhaust box and a molecular sieve between the two partitions, the molecular sieve being able to remove moisture mixed in with the gas.

[0013] The beneficial effects of the present invention are as follows: 1. During the electrolysis of the solution, the solution in the electrolysis tank gradually decreases. When the solution decreases to a certain amount, it can contact the start button through the float, thereby starting the water pump to inject the solution into the electrolysis tank, so as to achieve the function of automatically replenishing the electrolyte, making the operation more convenient.

[0014] 2. When performing electrolysis, the present invention can also start the drive motor to drive the scraper to rotate through the transmission between the drive gear, transmission gear, pinion and internal gear ring. When the scraper rotates, it can scrape off the impurities on the surface of the electrolytic plate, thereby cleaning the electrolytic plate. Attached Figure Description

[0029] A generator for hydrogen production, such as Figure 1-Figure 5 As shown, the device includes a manufacturing chamber 1, a swing plate 11, an electrolytic tank 3, a connecting pipe 4, a diaphragm 5, an oxygen exhaust pipe 9, a hydrogen exhaust pipe 10, an electrolysis structure, a gas storage mechanism, and a liquid addition mechanism. The swing plate 11 is rotatably connected to the upper right side of the manufacturing chamber 1. Electrolytic tanks 3 are connected to both the left and right sides of the manufacturing chamber 1. A connecting pipe 4 connects the lower sides of the two electrolytic tanks 3. Two diaphragms 5 are installed inside the connecting pipe 4. An oxygen exhaust pipe 9 is connected to the top of the left electrolytic tank 3 and extends out of the manufacturing chamber 1. Hydrogen exhaust pipes 10 are connected to both the front and rear sides of the top of the right electrolytic tank 3. The manufacturing chamber 1 is equipped with an electrolysis structure for electrolyzing the solution, a gas storage mechanism for storing hydrogen, and a liquid addition mechanism for adding solution.

[0030] like Figure 2 As shown, the electrolysis structure includes a battery 2, a conductive post 6, an electrolytic plate 7, and a conductive wire 8. The battery 2 is connected to the upper part of the manufacturing box 1. The conductive post 6 is connected to the middle of the inside of the electrolysis tank 3. A conductive wire 8 is connected between the left conductive post 6 and the positive electrode of the battery 2, and a conductive wire 8 is also connected between the right conductive post 6 and the negative electrode of the battery 2. Multiple electrolytic plates 7 are evenly spaced on the conductive post 6.

[0031] like Figure 3 As shown, the gas storage mechanism includes an exhaust box 101, a baffle 102, an exhaust pipe 103, and a valve 104. The exhaust box 101 is connected to the right side of the manufacturing box 1. The bottom of the exhaust box 101 is connected to the hydrogen exhaust pipe 10. The upper part of the exhaust box 101 is connected to the baffle 102. The front and rear sides of the baffle 102 are connected to the exhaust pipe 103. The exhaust pipe 103 is located on the left side of the swing plate 11. Opening the swing plate 11 can connect the external pipe to the exhaust pipe 103. A valve 104 is provided at the exhaust pipe 103.

[0032] like Figures 2-5 As shown, the liquid addition mechanism includes a liquid storage tank 111, a liquid injection pipe 112, a water pump 113, a liquid inlet pipe 114, a cylindrical stopper 115, and a control component. The liquid storage tank 111 is connected to the upper part of the manufacturing box 1. The bottom of the liquid storage tank 111 is connected to the two electrolysis tanks 3 by liquid injection pipes 112. A water pump 113 is installed at the bottom of the liquid storage tank 111. The outlet end of the water pump 113 is connected to the liquid injection pipe 112, and the inlet end of the water pump 113 is connected to the inside of the liquid storage tank 111. The top of the liquid storage tank 111 is connected to the liquid inlet pipe 114, and a cylindrical stopper 115 is inserted into the liquid inlet pipe 114.

[0033] like Figure 4 and Figure 5 As shown, the control assembly includes a guide sleeve 121, a float block 122, a start button 124, and a stop button 123. The guide sleeve 121 is connected to the upper part of the electrolysis tank 3 on the left side, and the guide sleeve 121 communicates with the interior of the electrolysis tank 3. The float block 122 is slidably connected inside the guide sleeve 121. The stop button 123 is connected to the top of the float block 122. The start button 124 is connected to the lower part of the guide sleeve 121. Both the start button 124 and the stop button 123 are electrically connected to the water pump 113.

[0034] This device can be used when hydrogen production is required. In operation, first open the cylindrical stopper 115, then inject the solution into the storage tank 111 through the inlet pipe 114. Since there is no solution in the electrolysis tank 3 at this time, the float 122 sinks and contacts the start button 124, thereby controlling the water pump 113 to operate, drawing the solution from the storage tank 111 and injecting it into the electrolysis tank 3 through the injection pipe 112, until the solution in the electrolysis tank 3 increases to the level that contacts the float 122. As the solution continues to be added, it will cause the float 122 to move upward. The upward movement of the float 122 will cause the shut-off button 123 to move upward. When the shut-off button 123 moves upward to contact the top of the guide sleeve 121, it controls the water pump 113 to shut off. At this time, the solution in the electrolysis tank 3 is sufficient for electrolysis. Then, the solution continues to be added to the storage tank 111 until an appropriate amount of solution is added. Then, the cylindrical stopper 115 is inserted into the inlet pipe 114, and then the battery can be controlled. 2. Discharge: Electrolytic plates 7 discharge through conductive pillars 6 and conductive wires 8. The positive electrode of the left electrolytic plate 7 discharges to electrolyze the solution into oxygen, which is discharged through the oxygen exhaust pipe 9. The negative electrode of the right electrolytic plate 7 discharges to electrolyze the solution into hydrogen, which enters the exhaust box 101 through the hydrogen exhaust pipe 10 and is stored in the exhaust box 101. When hydrogen needs to be extracted, the swing plate 11 can be opened, the pipe can be connected to the exhaust pipe 103, and the valve 104 can be opened to allow the hydrogen to be discharged. In this way, the device can be used to produce hydrogen. During the production process, as the solution in the electrolytic tank 3 decreases, the floating block 122 will gradually sink until it moves to contact the start button 124, thereby restarting the water pump 113 to add solution. After the solution is added to a certain amount, the floating block 122 floats up again and contacts the stop button 123 to control the water pump 113 to shut down, thus realizing the automatic replenishment of solution.

[0035] like Figure 6 and Figure 7As shown, it also includes a cleaning mechanism, which includes a drive motor 131, a drive gear 132, a transmission gear 133, an internal gear ring 134, a scraper 135, a connecting plate 136, and a pinion 137. The drive motor 131 is mounted in the middle of the upper part of the manufacturing housing 1. The drive gear 132 is connected to the output shaft of the drive motor 131. Transmission gears 133 are rotatably connected to the tops of both electrolytic tanks 3. The drive gear 132 meshes with the transmission gear 133. The lower part of the transmission gear 133 extends into the electrolysis tank 3 and is connected to a pinion 137. An internal gear ring 134 is rotatably connected to the upper part of the electrolysis tank 3. The internal gear ring 134 meshes with the pinion 137 so that the rotation of the pinion 137 can drive the internal gear ring 134 to rotate. Connecting plates 136 are connected to the left and right sides of the bottom of the internal gear ring 134. Multiple sets of scraper plates 135 are evenly spaced on the connecting plates 136. Each set of scraper plates 135 has two scraper plates and is sleeved on the upper and lower sides of the electrolysis plate 7.

[0036] The drive motor 131 is controlled to operate, which drives the drive gear 132 to rotate. When the drive gear 132 rotates, it drives the transmission gear 133 to rotate. When the transmission gear 133 rotates, it drives the pinion 137 to rotate. When the pinion 137 rotates, it drives the internal gear ring 134 to rotate. When the internal gear ring 134 rotates, it drives the connecting plate 136 and the scraper 135 to move. When the scraper 135 moves, it can clean the impurities on both sides of the electrolytic plate 7, thereby achieving the effect of cleaning the electrolytic plate 7.

[0037] like Figures 8-11 As shown, it also includes a drainage mechanism, which includes a discharge cylinder 141, a liquid guide pipe 142, a second valve 143, a turbine 144, and a bottom scraper 145. The discharge cylinder 141 is connected to the middle of the bottom of both electrolytic tanks 3. The bottom of the discharge cylinder 141 is connected to the liquid guide pipe 142. The rear sections of the two liquid guide pipes 142 are connected to each other and the ends pass through the manufacturing box 1. The second valve 143 is provided on the liquid guide pipe 142. The turbine 144 is rotatably connected inside the discharge cylinder 141. Three bottom scrapers 145 are evenly spaced on the top of the turbine 144. The bottom scrapers 145 are in contact with the bottom of the electrolytic tank 3.

[0038] When the solution needs to be discharged after the generator is finished, valve 143 can be opened. The solution in the electrolysis tank 3 will be discharged through the discharge cylinder 141 and the liquid guide pipe 142. When the solution is discharged, it will impact the turbine 144, causing the turbine 144 to rotate. The rotation of the turbine 144 can drive the scraper 135 to rotate. When the scraper 135 rotates, it can clean the bottom of the electrolysis tank 3. In this way, the solution can be discharged, and the bottom of the electrolysis tank 3 can be cleaned at the same time.

[0039] like Figure 12 As shown, it also includes a partition 151 and a molecular sieve 152. The lower part of the exhaust box 101 is connected to two partitions 151, and a molecular sieve 152 is provided between the two partitions 151. The molecular sieve 152 can remove moisture mixed in the gas. When hydrogen enters the exhaust box 101, the hydrogen will pass through the molecular sieve 152, thereby removing moisture from the hydrogen and drying the hydrogen, making the hydrogen purer.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
