Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic water production equipment, specifically an electrolytic water preparation device. Background Technology

[0002] Electrolyzed hydrogen-rich water refers to water that is rich in molecular hydrogen and is produced using electrolysis technology.

[0003] Extensive searches revealed CN215161247U, which discloses an electrolysis device for producing hydrogen-rich water. Through the ion-selective permeability of the ion exchange membrane, oxygen is generated in the first chamber between the anode structure and the ion exchange membrane, and acidic water flows out. Hydrogen is generated in the second chamber between the ion exchange membrane and the cathode structure, and alkaline hydrogen-rich water flows out.

[0004] Existing technologies can increase the rate of hydrogen-rich water production, but a large amount of acidic water is also generated during the production process, resulting in a significant waste of water resources. Therefore, an electrolytic water preparation device is needed to solve this problem. Utility Model Content

[0005] The purpose of this invention is to provide an electrolytic water preparation device that has the advantage of reducing wastewater production during production and solves the problem of excessive acidic water production during hydrogen-rich water production, which leads to waste.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electrolytic water preparation device, comprising an electrolytic cell, a cover movably installed on the top of the electrolytic cell, an ion exchange membrane movably installed inside the electrolytic cell, and an anode assembly and a cathode assembly movably installed on both sides of the ion exchange membrane inside the electrolytic cell, wherein the space occupied by the anode assembly is smaller than the space occupied by the cathode assembly; The inner side of the cover has a groove in the middle and a limiting block is embedded therein. The bottom of the limiting block contacts the top of the ion exchange membrane but is not fixedly connected.

[0007] Preferably, a voltage stabilizing mechanism is fixedly installed on the front of the electrolyzer, and a first drain pipe and a second drain pipe are respectively connected and installed on both sides of the bottom of the electrolyzer. A support frame is fixedly installed below the outer wall of the electrolyzer, and an installation frame is fixedly installed inside the electrolyzer. The ion exchange membrane is movably inserted into the inner side of the electrolyzer through the installation frame. The voltage stabilizing mechanism fixedly installed on the front of the electrolyzer ensures the stability of voltage and current during electrolysis, which is crucial for improving electrolysis efficiency and ensuring the quality of electrolysis products. The first drain pipe and the second drain pipe are located directly below the anode assembly and cathode assembly, respectively. This design facilitates the separate collection of acidic water generated by the anode and hydrogen-rich water generated by the cathode, achieving effective product separation. The support frame fixedly installed below the outer wall of the electrolyzer not only provides stable support but also ensures the stability of the electrolyzer during operation, avoiding damage caused by vibration or external forces. The movable insertion of the ion exchange membrane through the installation frame makes the replacement and maintenance of the ion exchange membrane more convenient, while also ensuring the stability and efficiency of the ion exchange membrane during electrolysis.

[0008] Preferably, the voltage regulator has two connecting wires movably inserted at its top. These two connecting wires are electrically connected to the anode and cathode components, respectively. A connection socket is located on the front of the voltage regulator. This design, with the two connecting wires electrically connected to the anode and cathode components, and the movable insertion design at the top of the voltage regulator, achieves stable current transmission and control of the electrolysis process. This design also facilitates the replacement and maintenance of the connecting wires. The connection socket on the front of the voltage regulator provides convenience for power connection while ensuring the stability and safety of the power supply.

[0009] Preferably, the first drain pipe and the second drain pipe are located directly below the anode assembly and the cathode assembly, respectively, and valves are fixedly installed at the bottom of both the first drain pipe and the second drain pipe. The valves fixedly installed at the bottom of both the first drain pipe and the second drain pipe in this design allow for precise control of the draining process, preventing accidental liquid loss when draining is not required, and facilitating rapid product discharge when needed.

[0010] Preferably, placement racks are fixedly installed on both sides of the mounting frame, and the anode and cathode assemblies are movably inserted into the sides of the electrolytic cell via these placement racks. This design, with placement racks fixedly installed on both sides of the mounting frame, allows the anode and cathode assemblies to be more securely inserted into the sides of the electrolytic cell, preventing loosening or damage caused by vibration or water flow impact. Simultaneously, this design facilitates the replacement and maintenance of the anode and cathode assemblies.

[0011] Preferably, the upper surface of the cover has openings on both sides, with connecting conduits for wiring. The tops of the anode and cathode assemblies extend into these conduits and are electrically connected to the connecting wires. The rear ends of both sides of the cover have openings and connecting vent pipes. This design provides a convenient passage for the wires on the tops of the anode and cathode assemblies, preventing wire clutter and potential damage. It also facilitates the replacement and maintenance of the connecting wires. The vent pipes on the rear ends of both sides of the cover allow for the timely release of gases (such as oxygen and hydrogen) generated during electrolysis, preventing pressure increases and potential hazards caused by gas accumulation. This design also helps maintain ventilation and heat dissipation inside the electrolytic cell.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, the space occupied by the anode assembly is smaller than that occupied by the cathode assembly. This design means that during electrolysis, the total amount of water molecules in the anode region electrolyzed to produce oxygen and hydrogen ions (thus forming acidic water) is relatively small because the water volume in the anode region is limited. In contrast, the cathode region, due to its larger space, can accommodate more water molecules for electrolysis, producing hydrogen gas (which dissolves in the water to form hydrogen-rich water) and hydroxide ions (making the water alkaline). An ion exchange membrane is located between the anode and cathode assemblies. It allows specific ions (such as hydrogen ions and hydroxide ions) to pass through, but blocks other ions (such as sodium ions, chloride ions, etc.) from passing through. During electrolysis, hydrogen ions generated at the anode migrate through the ion exchange membrane to the cathode region, combining with hydroxide ions generated at the cathode to form water, thereby reducing the production of acidic water. Simultaneously, the cathode region remains alkaline due to the accumulation of hydroxide ions, which is conducive to the formation of hydrogen-rich water. A groove is cut into the middle of the inner side of the cover body to embed a limiting block. The bottom of the limiting block contacts the top of the ion exchange membrane but is not fixedly connected. This design ensures the stability of the ion exchange membrane during electrolysis, preventing displacement or damage due to disturbances caused by water flow or bubbles. A stable ion exchange membrane can more effectively prevent ion mixing between different regions, thereby further reducing the generation of acidic water. In summary, by optimizing the spatial configuration of the anode and cathode components, utilizing the selective permeability of the ion exchange membrane, and designing stable limiting blocks, this water electrolysis preparation device can significantly reduce wastewater production, especially reducing the generation of acidic water, thus solving the problem of excessive acidic water generation and waste during hydrogen-rich water production. This design not only improves water resource utilization but also reduces production costs and environmental burden. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of this utility model is provided: an electrolytic water preparation device, including an electrolytic cell 1, a cover 2 movably installed on the top of the electrolytic cell 1, an ion exchange membrane 11 movably installed inside the electrolytic cell 1, and an anode assembly 31 and a cathode assembly 32 movably installed on both sides of the ion exchange membrane 11 in the electrolytic cell 1, respectively. The space occupied by the anode assembly 31 is smaller than the space occupied by the cathode assembly 32. A groove is cut in the middle of the inner side of the cover 2 and a limiting block 22 is embedded therein. The bottom of the limiting block 22 contacts the top of the ion exchange membrane 11 but is not fixedly connected.

[0017] Specifically, the space occupied by the anode assembly 31 is smaller than that occupied by the cathode assembly 32. This design means that during electrolysis, the total amount of water molecules in the anode region electrolyzed to produce oxygen and hydrogen ions, thus forming acidic water, is relatively small because the water volume in the anode region is limited. In contrast, the cathode region, due to its larger space, can accommodate more water molecules for electrolysis, producing hydrogen gas which dissolves in the water to form hydrogen-rich water and hydroxide ions, making the water alkaline. The ion exchange membrane 11 is located between the anode assembly 31 and the cathode assembly 32. It allows specific ions, such as hydrogen ions and hydroxide ions, to pass through, but prevents other ions, such as sodium ions and chloride ions, from passing through. During electrolysis, hydrogen ions generated at the anode migrate through the ion exchange membrane 11 to the cathode region, where they combine with hydroxide ions generated at the cathode to form water, thereby reducing the production of acidic water. At the same time, the cathode region remains alkaline due to the accumulation of hydroxide ions, which is conducive to the formation of hydrogen-rich water. A groove is cut in the middle of the inner side of the cover 2, and a limiting block 22 is embedded therein. The bottom of the limiting block 22 contacts the top of the ion exchange membrane 11 but is not fixedly connected. This design ensures the stability of the ion exchange membrane 11 during the electrolysis process, preventing it from shifting or being damaged by water flow or bubbles. A stable ion exchange membrane 11 can more effectively prevent ion mixing between different regions, thereby further reducing the generation of acidic water. In summary, by optimizing the spatial configuration of the anode assembly 31 and the cathode assembly 32, utilizing the selective permeability of the ion exchange membrane 11, and designing a stable limiting block 22, this water electrolysis preparation device can significantly reduce the amount of wastewater generated during production, especially reducing the amount of acidic water produced, thus solving the problem of excessive acidic water generation and waste during hydrogen-rich water production. This design not only improves water resource utilization but also reduces production costs and environmental burden. Example

[0018] To ensure the stability and efficiency of the electrolysis process, effective product separation is achieved, while also facilitating equipment maintenance and management, such as... Figure 2 and Figure 4As shown, in this embodiment, a voltage stabilizing mechanism 12 is fixedly installed on the front of the electrolytic cell 1. A first drain pipe 16 and a second drain pipe 17 are respectively connected and installed on both sides of the bottom of the electrolytic cell 1. A support frame 14 is fixedly installed below the outer wall of the electrolytic cell 1, and a mounting frame 15 is fixedly installed inside the electrolytic cell 1. The ion exchange membrane 11 is movably inserted into the inner side of the electrolytic cell 1 through the mounting frame 15. The voltage stabilizing mechanism 12, fixedly installed on the front of the electrolytic cell 1, ensures the stability of voltage and current during electrolysis, which is crucial for improving electrolysis efficiency and ensuring the quality of electrolysis products. The first drain pipe 16 and the second drain pipe 17 are located directly below the anode assembly 31 and the cathode assembly 32, respectively. This design facilitates the separate collection of acidic water generated by the anode and hydrogen-rich water generated by the cathode, achieving effective product separation. The support frame 14 fixedly installed below the outer wall of the electrolytic cell 1 not only provides stable support but also ensures the stability of the electrolytic cell 1 during operation, avoiding damage caused by vibration or external forces. The ion exchange membrane 11 is movably inserted into the mounting bracket 15, making the replacement and maintenance of the ion exchange membrane 11 more convenient, while also ensuring the stability and efficiency of the ion exchange membrane 11 during the electrolysis process.

[0019] Furthermore, the voltage regulator 12 has two connecting wires 33 movably inserted at its top. These two connecting wires 33 are electrically connected to the anode assembly 31 and the cathode assembly 32, respectively. A connection socket 121 is located on the front of the voltage regulator 12. In this design, the two connecting wires 33 are electrically connected to the anode assembly 31 and the cathode assembly 32, respectively. The movable insertion design at the top of the voltage regulator 12 achieves stable current transmission and control of the electrolysis process. This design also facilitates the replacement and maintenance of the connecting wires 33. The connection socket 121 on the front of the voltage regulator 12 provides convenience for power connection while ensuring the stability and safety of the power supply.

[0020] Furthermore, the first drain pipe 16 and the second drain pipe 17 are located directly below the anode assembly 31 and the cathode assembly 32, respectively, and valves 13 are fixedly installed at the bottom of both the first drain pipe 16 and the second drain pipe 17. The valves 13 fixedly installed at the bottom of both the first drain pipe 16 and the second drain pipe 17 in this design allow for precise control of the draining process, preventing accidental liquid loss when draining is not required, and facilitating rapid product discharge when needed.

[0021] Furthermore, mounting brackets 151 are fixedly installed on both sides of the mounting frame 15, and the anode assembly 31 and cathode assembly 32 are respectively movably inserted into the inner sides of the electrolytic cell 1 via the mounting brackets 151. In this design, the mounting brackets 151 fixedly installed on both sides of the mounting frame 15 allow the anode assembly 31 and cathode assembly 32 to be more securely inserted into the inner sides of the electrolytic cell 1, avoiding loosening or damage caused by vibration or water flow impact. At the same time, this design also facilitates the replacement and maintenance of the anode assembly 31 and cathode assembly 32. Example

[0022] To optimize the wiring layout and gas emission, and improve the ease of maintenance and operational safety of the electrolytic cell, such as... Figure 3 As shown, in this embodiment, holes are opened on both sides of the upper surface of the cover 2, and conduits 23 are installed therethrough. The tops of the anode assembly 31 and the cathode assembly 32 extend into the conduits 23 and are electrically connected to the connecting wires 33. Exhaust pipes 21 are opened at the rear ends of both sides of the upper surface of the cover 2. The conduits 23, with holes on both sides of the upper surface of the cover 2, provide a convenient channel for the wires on the tops of the anode assembly 31 and the cathode assembly 32, avoiding wire clutter and potential damage. This design also facilitates the replacement and maintenance of the connecting wires 33. The exhaust pipes 21, with holes at the rear ends of both sides of the upper surface of the cover 2, can promptly discharge gases such as oxygen and hydrogen generated during electrolysis, avoiding pressure increases and potential dangers caused by gas accumulation. This design also helps maintain ventilation and heat dissipation inside the electrolytic cell 1.

[0023] When using this invention, ensure that the electrolytic cell 1 is correctly placed on the support frame 14 and that all components of the electrolytic cell 1 are in place. Check that the anode assembly 31 and cathode assembly 32 are correctly installed on both sides of the inside of the electrolytic cell 1 via the placement frame 151, and ensure that their relative positions with the ion exchange membrane 11 are correct. Check that the valves 13 of the first drain pipe 16 and the second drain pipe 17 are closed to prevent accidental liquid leakage before electrolysis begins. Connect the connection socket 121 of the voltage stabilizing mechanism 12 to the power supply to ensure a stable power supply. Add an appropriate amount of water to the electrolytic cell 1, ensuring that the water level covers the anode assembly 31 and cathode assembly 32, but does not exceed the capacity limit of the electrolytic cell 1. Carefully place the cover 2 on top of the electrolytic cell 1, ensuring that the limiting block 22 is correctly in contact with the top of the ion exchange membrane 11. Pass the wires at the top of the anode assembly 31 and cathode assembly 32 through the conduit 23 and connect them correctly to the connecting wire 33. Ensure that the exhaust pipe 21 is not blocked. To release the generated gas during electrolysis, turn on the voltage regulator 12 and supply power to the anode assembly 31 and cathode assembly 32 via the connection socket 121. After electrolysis begins, observe whether gas is discharged from the exhaust pipe 21 and whether bubbles are generated inside the electrolytic cell 1. Water near the anode assembly 31 will be electrolyzed to produce oxygen and acidic water, while water near the cathode assembly 32 will be electrolyzed to produce hydrogen and hydrogen-rich water. When the required electrolysis time or output is reached, turn off the voltage regulator 12, disconnect the power supply, open the valve 13 of the first drain pipe 16 to collect the acidic water generated below the anode assembly 31, and open the valve 13 of the second drain pipe 17 to collect the hydrogen-rich water generated below the cathode assembly 32. After electrolysis is completed, close all valves 13, disconnect the power supply, and allow the electrolytic cell 1 to cool. Clean the inside of the electrolytic cell 1, including the anode assembly 31, cathode assembly 32, and ion exchange membrane 11, to ensure that there are no residues. Check all components for damage and replace them promptly if any are damaged or worn.
