EMBODIMENT

Obviously, the embodiments described below are only some of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the patent, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the patent.

[0039] As Figure 1As shown, the specific embodiment provides a visual composite electrode plate of an alkaline water electrolyzer, which comprises an anode electrode frame 3, a cathode electrode frame 1 and a conductive electrode plate 4. The cathode electrode frame 1 and the anode electrode frame 3 are coaxially arranged. The outer and inner circles of the anode electrode frame 3 and the cathode electrode frame 1 have the same size. The inner circle of the anode electrode frame 3 and the inner circle of the cathode electrode frame 1 are used to place a support net. The cathode electrode frame 1 and the anode electrode frame 3 are made of transparent and non-conductive materials. The cathode electrode frame 1 and the anode electrode frame 3 are detachably connected. The conductive electrode plate 4 is arranged between the cathode electrode frame 1 and the anode electrode frame 3. The conductive electrode plate 4 is made of conductive material.

[0040] In the specific embodiment, the anode electrode frame 3 and the cathode electrode frame 1 are made of transparent materials, so that the internal flow field and electrode changes of the electrolyzer can be directly observed. By arranging the conductive electrode plate 4, the defect that the transparent and non-conductive materials cannot conduct electricity is solved. The conductive electrode plate 4 can completely replace the function of the electrode plate in the electrolyzer. In addition to achieving the technical effect of visualizing the electrolyzer, the conductive electrode plate 4 can also avoid the stray current, bypass current and parasitic current generated when the metal electrode plate is used in the prior art, thereby avoiding energy loss.

[0041] As shown in Figure 4 , Figure 8 and Figure 9 , in order to facilitate the assembly of the composite electrode plate itself and the installation of other components in the electrolyzer, in the specific embodiment, the cathode electrode frame 1 comprises a mounting end surface one 10. The mounting end surface one 10 is close to the conductive electrode plate 4. A mounting groove one 20 is coaxially arranged on the mounting end surface one 10. The conductive electrode plate 4 is arranged in the mounting groove one 20. Further, the anode electrode frame 3 comprises a mounting end surface two 21. The mounting end surface two 21 is away from the conductive electrode plate 4. The mounting end surface two 21 is provided with a mounting groove two 18 and a mounting groove three 17. The mounting groove two 18 and the mounting groove three 17 are coaxially arranged with the inner circle of the anode electrode frame 3. The diameter of the mounting groove two 18 is smaller than that of the mounting groove three 17. The mounting groove two 18 is used to install the anode electrode. The mounting groove three 17 is used to install the diaphragm.

[0042] As shown in Figures 2 to 9As shown, in order to facilitate the smooth flow of alkaline water and the shunting of oxygen and hydrogen, in the embodiment, the cathode pole frame 1 and the anode pole frame 3 are respectively provided with four through holes 7, the axial direction of the through holes 7 is parallel to the axial direction of the anode pole frame 3 or the cathode pole frame 1, the four through holes 7 on the cathode pole frame 1 and the four through holes 7 on the anode pole frame 3 are arranged opposite to each other, and through the opposite arrangement, i.e., the coaxial arrangement of the through holes 7, water flow channels, oxygen flow channels and hydrogen flow channels are formed. The cathode pole frame 1 includes a mounting end face four 19, which is away from the conductive pole plate 4. The mounting end face four 19 is provided with a water guide groove one 14 and a hydrogen guide groove 11. The water guide groove one 14 communicates one of the through holes 7 on the cathode pole frame 1 (in the embodiment, the through hole 7 is located at the lower part of the cathode pole frame 1) with the inner ring of the cathode pole frame 1. The hydrogen guide groove 11 communicates another through hole 7 on the cathode pole frame 1 (in the embodiment, the through hole 7 is located at the upper part of the cathode pole frame 1. Such an arrangement conforms to the flow direction of the gas and improves the flow efficiency of hydrogen) with the inner ring of the cathode pole frame 1. The mounting end face two 21 is provided with a water guide groove two 16 and an oxygen guide groove 15. The water guide groove two 16 communicates one of the through holes 7 on the anode pole frame 3 (in the embodiment, the through hole 7 is located at the lower part of the anode pole frame 3) with the inner ring of the anode pole frame 3. The oxygen guide groove 15 communicates another through hole 7 on the anode pole frame 3 (in the embodiment, the through hole 7 is located at the upper part of the anode pole frame 3. Such an arrangement conforms to the flow direction of the gas and improves the flow efficiency of oxygen) with the inner ring of the anode pole frame 3. The water guide groove one 14 and the water guide groove two 16 are both arranged below and staggered. The hydrogen guide groove 11 and the oxygen guide groove 15 are both arranged above and staggered. After such an arrangement, the alkaline water enters the two end faces of the conductive pole plate 4 through the two through holes 7 at the lower part to generate corresponding electrochemical reactions, and the oxygen generated at the side of the anode pole frame 3 and the hydrogen generated at the side of the cathode pole frame 1 flow to different directions after converging through the different two through holes 7 at the upper part, thereby realizing shunting.

[0043] As Figures 2 to 9As shown, since the conductive plate 4 is located between the cathode pole frame 1 and the anode pole frame 3 and is made of different materials, there is a gap between the two end faces of the conductive plate 4 and the cathode pole frame 1 and the anode pole frame 3. In order to avoid leakage and mutual penetration of hydrogen and oxygen, in the specific embodiment, a sealing gasket 2 is further arranged between the conductive plate 4 and the anode pole frame 3. The outer diameter of the sealing gasket 2 is not less than the outer diameter of the anode pole frame 3 or the cathode pole frame 1, and the inner diameter of the sealing gasket 2 is less than the diameter of the conductive plate 4. By arranging the sealing gasket 2, the gap between the three can be effectively blocked to reduce leakage. Further, in order to improve the sealing performance of the composite plate, in the specific embodiment, the anode pole frame 3 includes a mounting end face three 22 close to the conductive plate 4. The corresponding positions of the mounting end face one 10 and the mounting end face three 22 are provided with a sealing groove group one 8 and a sealing groove group two 9. That is, the sealing groove group one 8 of the mounting end face one 10 is arranged opposite to the sealing groove group one 8 on the mounting end face three 22, and the sealing groove group two 9 of the mounting end face one 10 is arranged opposite to the sealing groove group two 9 on the mounting end face three 22. The sealing groove group one 8 and the sealing groove group two 9 each include a plurality of coaxial sealing grooves. By arranging the sealing grooves, the extrusion effect on the sealing ring can be enhanced, the sealing ring can be elastically deformed, the sealing distance can be increased, and the sealing effect can be further improved. In order to realize the flow of alkaline water, oxygen and hydrogen, a spacing is arranged between the sealing groove group one 8 and the sealing groove group two 9, that is, the diameter of the smallest sealing groove in the sealing groove one is greater than the diameter of the largest sealing groove in the sealing groove two. The four through holes 7 are arranged between the sealing groove group one 8 and the sealing groove group two 9. By arranging the sealing groove group one 8, the sealing performance of the anode pole frame 3 and the cathode pole frame 1 close to the edge position can be enhanced, and water leakage can be effectively prevented. By arranging the sealing groove two, the sealing performance of the anode pole frame 3 and the cathode pole frame 1 close to the inner circle position can be enhanced, and mutual penetration of oxygen and hydrogen can be prevented, that is, the sealing effect is ensured, and the flow is not affected.

[0044] As shown in Figure 3 and Figure 8 Since a sealing ring is arranged between adjacent composite plates in the multi-chamber electrolytic cell, in order to enhance the sealing effect of adjacent composite plates, in the specific embodiment, the corresponding positions of the mounting end face four 19 and the mounting end face two 21 are provided with a sealing groove group three 13. The sealing groove group three 13 includes a plurality of sealing grooves, and the sealing groove group three 13 is arranged opposite to the sealing groove group one 8.

[0045] As shown in Figure 3 and Figure 8As shown, due to the deformation of the sealing ring between adjacent composite plates under the compression of the anode frame 3 and the cathode frame 1, wrinkles will form in the part between the sealing groove group 1 8 and the sealing groove group 2 9. These wrinkles will then fill the water guide groove 1 14 and the water guide groove 2 16, affecting flow. Therefore, in this specific embodiment, two anti-clogging grooves 12 are provided on both the mounting end face 4 19 and the mounting end face 2 21. The two anti-clogging grooves 12 on the mounting end face 4 19 are respectively connected to the water guide groove 1 14 and the hydrogen guide groove 11, and the two anti-clogging grooves 12 on the mounting end face 2 21 are respectively connected to the water guide groove 1 14 and the hydrogen guide groove 11. The anti-clogging groove 12 is not connected to the water guide groove 16 or the oxygen guide groove 15. The depth of the anti-clogging groove 12 is less than the depth of the water guide groove 14, the water guide groove 16, the oxygen guide groove 15, or the hydrogen guide groove 11. The anti-clogging groove 12 is provided with support plates, and multiple support plates span the corresponding water guide groove 14, water guide groove 16, oxygen guide groove 15, and hydrogen guide groove 11 respectively. By setting the support plates and the anti-clogging groove 12, the sealing ring can be prevented from deforming and blocking the corresponding guide groove. The guide groove can always achieve communication between the corresponding through hole 7 and the inner ring, ensuring the smooth flow of alkaline water, oxygen, and hydrogen.

[0046] The anode frame 3 and the cathode frame 1 can be made of acrylic material. In this specific embodiment, both the anode frame 3 and the cathode frame 1 are made of quartz glass. By using quartz glass, not only can internal visualization be achieved, but also high temperature resistance and lightweight effect are achieved. The conductive electrode plate 4 is made of corrosion-resistant metal material, such as stainless steel or nickel-plated carbon steel, which can improve the corrosion resistance of this composite electrode plate.

[0047] like Figure 12 As shown, the multi-chamber alkaline water electrolysis cell contains multiple composite electrode plates and end plates 6 at both ends. An anode electrode, a cathode electrode, and a diaphragm are also provided between two composite electrode plates. During installation, the anode electrode is close to the support mesh of the inner ring of the anode electrode frame 3, and the cathode electrode is close to the support mesh of the inner ring of the cathode electrode frame 1. A diaphragm is also provided between adjacent anode and cathode electrodes, and a sealing ring is provided between different chambers. Four tension bolts 5 are provided between the two end plates 6. Through the action of the tension bolts 5, the multiple composite electrode plates and the sealing rings between them are pressed together.

[0048] The working process of this composite electrode plate is as follows:

[0049] The alkaline water enters the two end faces of the conductive electrode plate 4 through the water guide groove one 14 and the water guide groove two 16 from the through hole 7 at the lower part of the composite electrode plate, respectively generates hydrogen at the cathode electrode at the cathode electrode frame 1, the hydrogen flows upwards, enters the upper through hole 7 through the upper hydrogen guide groove 11, generates oxygen at the anode electrode at the anode electrode frame 3, the oxygen flows upwards, enters the upper through hole 7 through the upper oxygen guide groove 15, and the oxygen and the hydrogen are separated; the anode electrode frame 3 and the cathode electrode frame 1 are transparent, so that the gas flow in the electrolytic tank and the electrode color change can be directly observed, and the electrolytic tank structure can be optimized.
