Description

Technical Field

[0001] This utility model relates to the field of hydrogen production by water electrolysis, and in particular to an electrolyzer with a novel structure. Background Technology

[0002] Electrolytic cells require a support structure during use. In practical applications, existing copper foil electrolytic cell support structures, due to the arc-shaped side surfaces and friction, may cause the cell's center of gravity to be located in the upper half, posing a risk of rolling and tipping. Furthermore, the cylindricity control of the inner arc surface of the support plate is inaccurate. Since the existing anode support plate is supported only by two thin stainless steel side plates, which lack rigidity, the support effect on the anode support plate is poor.

[0003] Patent CN205024334U discloses a support structure for a copper foil electrolytic cell, including a support base and an electrolytic cell support. The electrolytic cell support includes two opposing cell support frames, each with a side plate and an arc-shaped support groove. An outer ring plate is located on the inner wall of the arc-shaped support groove, and an inner ring plate is located at the inner end of the outer ring plate. An inlet tank support frame is connected between the bottom of the inner ring plates of the two cell support frames. An overflow tank support rod is connected between the two ends of the inner ring plates of the two cell support frames. A reinforcing support rod is also connected between the inner ring plates of the two cell support frames. Connecting holes are provided on the outer ring plate, the inlet tank support frame, the overflow tank support rod, and the reinforcing support rod. A reinforcing rod is connected between the bottom of the side plates of the two cell support frames. A support frame connecting plate is located along the length of the lower end of the side plate. This utility model has high overall structural strength, a large contact support area, prevents processing deformation, ensures the roundness and flatness of the side plates, provides good sealing effect, and has a long service life.

[0004] However, the use of curved contact surfaces in the comparison documents still makes it difficult to solve the rolling problem when the gravitational potential energy is high.

[0005] An electrolytic cell is needed to solve the above problems. Utility Model Content

[0006] This invention addresses the problem that in existing electrolytic cells, due to the friction caused by the curved side surface of the cell under support, the center of gravity may be located in the upper half of the cell, posing a risk of rolling and overturning. Furthermore, the cylindricity of the inner curved surface of the support plate is not precisely controlled. Additionally, the existing anode support plate is supported only by two thin stainless steel side plates, which lack rigidity and provide poor support. This invention provides a novel electrolytic cell structure that solves these problems.

[0007] This utility model provides a novel electrolytic cell structure, including several tie rods, an electrolytic cell body, and a pair of end plates. The end plates are located at both ends of the electrolytic cell body and are circular plate structures. The electrolytic cell body is a cylindrical structure, and the diameter of the end plates is larger than the diameter of the electrolytic cell. The tie rods are straight rod structures with threads at both ends. The two ends of the tie rods are fastened to the inner ring of the outer circumference of the end plates. The fastening ends of the tie rods are equipped with a balancer and a detachable counterweight ball. A center adjustment mechanism is provided in the middle of the outer plate surface of the end plates.

[0008] In a preferred embodiment of the novel electrolytic cell described in this utility model, the end plate includes an end plate body, several fastening holes, an end plate water inlet, four adjusting bases, four auxiliary counterweights, one main counterweight, and four threaded rods. The end plate body is a plate structure. The fastening holes are evenly distributed around the outer circumference of the end plate, and the end plate water inlet is located within the fastening holes. The adjusting bases are blocks fixed to the end plate and have screw holes parallel to the surface of the end plate body. The screw holes of the adjusting bases are collinear in pairs, and the axes of the two screw holes are perpendicular to each other. The threaded rods pass through the screw holes and are hinged to the auxiliary counterweights. The main counterweight is a two-tiered block. The first tier of the main counterweight is a cuboid, and the second tier is a cylinder. The cylinder and the cuboid share a common centerline. The diameter of the cylinder is larger than the longest diameter of the cuboid connecting the cylindrical surface. The auxiliary counterweights and the end plate are fitted with the two end faces of the cylindrical main counterweight, and the inner surface of the auxiliary counterweight contacts the cuboid side surface of the main counterweight.

[0009] In a preferred embodiment of the novel electrolytic cell described in this utility model, the electrolytic cell body is composed of several stacked electrolytic cell chambers. Each electrolytic cell chamber includes an anode plate, an anode electrode, a diaphragm, a cathode electrode, a sealing gasket, and a cathode plate. A diaphragm mounting groove is provided on one side of the anode plate, and the diaphragm is installed in the diaphragm mounting groove. The anode plate, anode electrode, diaphragm, cathode electrode, sealing gasket, and cathode plate are stacked sequentially. Water inlets are provided at corresponding positions on the end plates, anode plate, cathode plate, and sealing gasket.

[0010] In a preferred embodiment of the novel electrolytic cell described in this utility model, the electrolytic cell body is further provided with an intermediate electrode plate, which is disposed between the electrolytic cell chambers, and the number of electrolytic cell chambers on both sides of the intermediate electrode plate is equal.

[0011] In a preferred embodiment of the novel electrolytic cell described in this utility model, the pull rod includes a screw, an insulating washer, a disc spring, a disc spring guide ring, a disc spring guide sleeve, a tension nut, a level, and a counterweight ball. The two ends of the screw pass through the fastening holes of the end plate. The insulating washer, the disc spring guide ring, the disc spring, the disc spring guide sleeve, and the tension nut are installed sequentially from the inside to the outside on the threads on the outer side of the end plate. The level is installed at both ends of the screw. The counterweight ball has a screw hole and is installed at the end of the screw outside the tension nut through the screw hole.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) This device changes the overall center of gravity by using an external structure, so that the overall center of gravity is concentrated in the lower half of the device, reducing gravitational potential energy while ensuring that the center of gravity is located in the middle of the device as much as possible.

[0014] (2) By manually adjusting the structure, the overall center of gravity can be restored as much as possible, reducing the metal fatigue problem caused by the imbalance of the support structure. Attached Figure Description
