Description

Technical Field

[0001] The utility model relates to the technical field of water electrolyzers, in particular to a rubber pad group specially used for sheet-shaped water electrolyzers. Background Art

[0002] A new type of sheet water electrolyzer group with the Chinese authorized announcement number CN213357770U. The pressure relief valve can release air to the outside when the pressure in the electrolyzer is too high, and return to normal after the pressure is released to ensure the continuous operation of the electrolyzer. It uses a rubber pad set specially designed for sheet electrolyzers. It is formed by two sets of rubber pads nested, plus the hollow trough body at both ends of the rubber pad set, to form an independent electrolysis unit with 3 electrolysis chambers, and then such independent electrolysis units are stacked, and a heat dissipation wind tunnel is left between each group of electrolysis units to form the sheet electrolyzer we are using.

[0003] Conventional electrolyzers are mostly composed of a simple stacking and pressing of plates + rubber pads + plates + rubber pads to form an overall electrolyzer. Such an assembly is usually accompanied by the problem of heat dissipation that cannot be solved. The temperature of the part closer to the middle of the electrolyzer will be higher, which will cause the rubber pad in the middle to be threatened by higher temperatures and age faster. Therefore, we have proposed a rubber pad assembly specifically for sheet-shaped water electrolyzers. Utility Model Content

[0004] The purpose of the utility model is to provide a rubber pad assembly specifically for a sheet-shaped water electrolyzer, so as to solve the problem that conventional electrolyzers mentioned in the above background technology mostly use a simple overlapping and compacting method of electrode plate + rubber pad + electrode plate + rubber pad to form an overall electrolyzer, and such an assembly is generally accompanied by the problem of heat dissipation that cannot be solved. The temperature of the part closer to the middle of the electrolyzer will be higher, which will cause the rubber pad in the middle part to be threatened by higher temperature and accelerate the aging speed.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A rubber pad group specially used for a sheet-shaped water electrolyzer comprises a hollow insulating pad, a plate insulating pad is nested in the step of the hollow insulating pad, a mounting groove is provided in the plate insulating pad, a second electrolytic plate is embedded in the mounting groove, and a first electrolytic plate is embedded between the hollow insulating pad and the rubber pad of the plate insulating pad.

[0007] As a preferred solution of the present invention, the first electrolytic plate and the second electrolytic plate have the same length, and the first electrolytic plate and the second electrolytic plate are both rectangular in shape.

[0008] As a preferred solution of the utility model, the shape of the hollow insulating pad is rectangular, and a plurality of equidistantly distributed circular holes are provided at the edge of the hollow insulating pad, and the radii of the plurality of circular holes are the same.

[0009] As a preferred solution of the utility model, the shape of the pole plate insulating pad is rectangular, and the pole plate insulating pad is arranged on the side of the hollow insulating pad.

[0010] As a preferred solution of the utility model, the shape of the mounting groove is rectangular, and the mounting groove is opposite to the second electrolytic plate.

[0011] As a preferred solution of the present invention, the thickness of the hollow insulating pad and the plate insulating pad are the same.

[0012] As a preferred solution of the utility model, a through hole is opened at the edge of the electrode plate insulating pad.

[0013] As a preferred solution of the present invention, the thickness of the first electrolytic plate and the second electrolytic plate are the same.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. In the utility model, a rubber pad group specially used for a sheet-shaped water electrolyzer is composed of a hollow insulating pad and a plate insulating pad through the coordinated use of a hollow insulating pad, a plate insulating pad and two electrolytic plates. Each group of rubber pad groups is used in an electrolytic unit, and the assembly is simple and only requires mutual nesting. Two electrolytic plates are built in, and three electrolytic chambers can be formed. The overall width is small and there will be no problem of excessive temperature in the middle.

[0016] 2. In the utility model, the phenomenon that the temperature of the part closer to the middle of the electrolytic cell becomes higher can be avoided, and the rubber pad in the middle part can be prevented from being threatened by higher temperature, thereby delaying the aging speed of the rubber pad and protecting the rubber pad.

[0027] Among them, through the coordinated use of the hollow insulating pad 1, the plate insulating pad 2 and the two electrolytic plates, the rubber pad group specially used for the sheet water electrolyzer is composed of two parts: the hollow insulating pad 1 and the plate insulating pad 2. Each group of rubber pad groups is used in an electrolytic unit. The assembly is simple and only requires nesting with each other. Two electrolytic plates are built in to form three electrolytic chambers. The overall width is small and there will be no problem of excessive temperature in the middle.
