Description

Technical Field

[0001] This utility model relates to the technical field of water electrolysis for hydrogen production, specifically to a water electrolysis for hydrogen production. Background Technology

[0002] Hydrogen production via water electrolysis is a process that uses the electrolysis of water to produce hydrogen gas. An electrolyzer is a device used to carry out the electrolysis reaction, in which water molecules are decomposed into hydrogen and oxygen under the influence of an electric current. Specifically, a water electrolysis hydrogen production electrolyzer is a device or equipment used to decompose water (H2O) into hydrogen (H2) and oxygen (O2). The electrolyzer uses electrical energy to drive the electrolysis reaction of water molecules; this reaction occurs by applying a voltage between the anode and cathode.

[0003] However, it still has some drawbacks. For example, the current water electrolysis hydrogen production electrolyzer has a relatively simple structure. The electrode plates are usually directly fixed without any limiting or fixing. The electrode plates are easy to fall off or deviate from their intended positions, and are not easy to disassemble and install. Moreover, when electrolyzing water, a certain amount of heat is generated, which causes the electrolyte temperature to rise, resulting in increased conductivity of the electrolyte. This leads to excessive local current density, causing uneven reactions on the electrode surface, and may even exacerbate the polarization of the electrode.

[0004] To address the aforementioned issues, this application proposes a water electrolysis hydrogen production electrolyzer. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water electrolysis hydrogen production electrolyzer, comprising an electrolyzer body, wherein an inlet and an outlet are fixedly installed at the front end of the electrolyzer body, the inlet being located above the outlet, a support base is fixedly installed on one side of the electrolyzer body, and a heat dissipation mechanism is fixedly installed at the upper end of the support base.

[0007] Preferably, an installation plate is detachably installed on the upper end of the electrolytic cell, a connecting bolt is detachably installed on the upper end of the installation plate, a drive box is fixedly installed on the lower end of the installation plate, and a clamping assembly is movably installed in the inner cavity of the drive box.

[0008] Preferably, the heat dissipation mechanism includes a cooling fan, a conveying pipe, a first air outlet pipe and a second air outlet pipe. The conveying pipe is fixedly installed on one side of the cooling fan, and the first air outlet pipe and the second air outlet pipe are fixedly installed on the inner side of the conveying pipe.

[0009] Preferably, the clamping assembly includes an adjustment knob, a connecting rod, a driving gear, a driven gear plate, and a fixing rod. The lower end of the adjustment knob is fixedly connected to the connecting rod, the lower end of the connecting rod is fixedly mounted with the driving gear, the outer wall of the driving gear is movably mounted with the driven gear plate, one side of the driven gear plate is fixedly connected to the fixing rod, and one side of the fixing rod is fixedly mounted with the clamping plate.

[0010] Preferably, the number of mounting plates and the number of electrode sheets are both multiple sets, and the lower end of the connecting bolt is detachably connected to the upper end of the electrolytic cell through the mounting plate.

[0011] Preferably, the first air outlet pipe is located on one side of the electrolytic cell, and the second air outlet pipes are fixedly located at both ends of the electrolytic cell, and there are multiple sets of the second air outlet pipes.

[0012] Preferably, the adjustment knob is movably located at the upper end of the mounting plate, the connecting rod and the drive gear are movably located in the inner cavity of the drive box, and the clamping plates are respectively located at both ends of the electrode sheet.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model, through the coordinated operation of the cooling fan, conveying pipe, first air outlet pipe, and second air outlet pipe in the heat dissipation mechanism, reduces the possibility of damage to the electrolytic cell body and top cover due to heat generation and lack of heat dissipation during operation, accelerates heat transfer and dissipation, and improves the utilization rate of the device. The arrangement of the first air outlet pipe and the second air outlet pipe also increases the heat dissipation range.

[0015] This invention utilizes a clamping assembly with an adjusting knob, connecting rod, driving gear, driven gear plate, fixing rod, and clamping plate to facilitate the fixing and clamping of electrode sheets, preventing them from moving. Two sets of clamping plates can hold electrode sheets of different sizes. Adjusting the connecting rod drives the driving gear at its lower end, which in turn moves the driven gear plate, which in turn moves the clamping plate on one side of the fixing rod. This causes the two sets of clamping plates to move towards each other, securing the electrode sheets and preventing them from easily falling off or deviating from their intended position, thus improving stability and facilitating electrode sheet replacement.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-2 This utility model provides a technical solution: a water electrolysis hydrogen production electrolyzer, including an electrolyzer body 1. An inlet 2 and an outlet 3 are fixedly installed at the front end of the electrolyzer body 1. The inlet 2 is located above the outlet 3. A support base 4 is fixedly installed on one side of the electrolyzer body 1. A heat dissipation mechanism 5 is fixedly installed at the upper end of the support base 4. An installation plate 6 is detachably installed at the upper end of the electrolyzer body 1. A connecting bolt 7 is detachably installed at the upper end of the installation plate 6. A drive box 8 is fixedly installed at the lower end of the installation plate 6. A clamping assembly 9 is movably installed in the inner cavity of the drive box 8. The number of installation plates 6 and the number of electrode plates 10 are both multiple sets. The lower end of the connecting bolt 7 is detachably connected to the upper end of the electrolyzer body 1 through the installation plate 6, which facilitates the disassembly and installation of the electrode plates.

[0023] In this embodiment, as Figure 3As shown, the heat dissipation mechanism 5 includes a cooling fan 501, a conveying pipe 502, a first air outlet 503, and a second air outlet 504. The conveying pipe 502 is fixedly installed on one side of the cooling fan 501, and the first air outlet 503 and the second air outlet 504 are fixedly installed on the inner side of the conveying pipe 502. The first air outlet 503 is located on one side of the electrolytic cell body 1, and the second air outlet 504 is fixedly located at both ends of the electrolytic cell body 1. There are multiple sets of second air outlet 504. Through the cooperation of the cooling fan 501, the conveying pipe 502, the first air outlet 503, and the second air outlet 504 in the heat dissipation mechanism 5, the possibility of damage to the electrolytic cell body and top cover due to heat generation and lack of heat dissipation during operation is reduced. The heat transfer and dissipation are accelerated, improving the utilization rate of the device. The setting of the first air outlet 503 and the second air outlet 504 increases the heat dissipation range.

[0024] In this embodiment, as Figure 4 As shown, the clamping assembly 9 includes an adjusting knob 901, a connecting rod 902, a driving gear 903, a driven gear plate 904, and a fixing rod 905. The lower end of the adjusting knob 901 is fixedly connected to the connecting rod 902, and the lower end of the connecting rod 902 is fixedly mounted with the driving gear 903. The driven gear plate 904 is movably mounted on the outer wall of the driving gear 903. The fixing rod 905 is fixedly connected to one side of the driven gear plate 904, and a clamping plate 906 is fixedly mounted on one side of the fixing rod 905. The adjusting knob 901 is movably located at the upper end of the mounting plate 6, and the connecting rod 902 and the driving gear 903 are movably located in the inner cavity of the drive box 8. The clamping plates 906 are located at both ends of the electrode sheet 10. The clamping assembly 9 consists of an adjusting knob 901, a connecting rod 902, a driving gear 903, a driven gear 904, and a fixing rod 905. The interaction of the driving gear 903, driven gear plate 904, fixing rod 905, and clamping plate 906 facilitates the fixing and clamping of the electrode sheet 10, preventing it from moving. Two sets of clamping plates 906 can clamp the electrode sheet 10, simultaneously clamping electrode sheets 10 of different sizes. Adjusting the driving gear 903 at the lower end of the connecting rod 902 causes the driving gear 903 to move the driven gear plate 904, which in turn moves the clamping plate 906 on one side of the fixing rod 905. This causes the two sets of clamping plates 906 to move towards each other, clamping and fixing the electrode sheet 10, preventing it from easily falling off or deviating from its intended position, improving stability, and facilitating the replacement of the electrode sheet 10.

[0025] Working principle:

[0026] Through the coordinated operation of the cooling fan 501, conveying pipe 502, first air outlet 503, and second air outlet 504 in the cooling mechanism 5, the possibility of damage to the electrolytic cell body and top cover due to heat generation and lack of heat dissipation during operation is reduced. Heat transfer and dissipation are accelerated, improving the utilization rate of the device. The arrangement of the first air outlet 503 and second air outlet 504 increases the heat dissipation range. The coordinated operation of the adjusting knob 901, connecting rod 902, driving gear 903, driven gear plate 904, fixing rod 905, and clamping plate 906 in the clamping assembly 9 facilitates the adjustment of the electrode plates. The electrode sheet 10 is fixedly clamped to prevent it from moving. Two sets of clamping plates 906 are provided to clamp the electrode sheet 10, and can clamp electrode sheets 10 of different sizes at the same time. By adjusting the driving gear 903 at the lower end of the connecting rod 902, the driving gear 903 drives the driven gear plate 904 to move, and then drives the clamping plate 906 on one side of the fixed rod 905 to move. This causes the two sets of clamping plates 906 to move towards each other, so that the clamping plates 906 clamp and fix the electrode sheet 10, preventing the electrode sheet 10 from easily falling off or deviating from the predetermined position, improving stability, and also facilitating the replacement of the electrode sheet 10.
