[0032] Combine the following Figure 1-Figure 8 Various embodiments of the invention are described.

[0033] Reference Figure 1 and Figure 2 , the sealing assembly 100 provided by the present invention includes a first sealing gasket 110 and a second sealing gasket 120, and a diaphragm 130 is provided between the first sealing gasket 110 and the second sealing gasket 120. Specifically, the first sealing gasket 110 and the second sealing gasket 120 are both annular structures, and their shapes can be selected and designed according to different electrolytic cells 200, and no specific restrictions are made here. Specifically, for a square electrolytic cell 200, the specific structure of the first sealing gasket 110 and the second sealing gasket 120 can be a square annular structure, and for a circular electrolytic cell 200, the specific structure of the first sealing gasket 110 and the second sealing gasket 120 can be a circular annular structure. Since the first sealing gasket 110 and the second sealing gasket 120 are placed between two adjacent electrodes during specific use, and the two adjacent electrodes are of opposite sex. Therefore, the first sealing gasket 110 and the second sealing gasket 120 are arranged on the anode side as an anode sealing gasket, and the one arranged on the cathode side is a cathode sealing gasket.

[0034] The first sealing gasket 110 and the second sealing gasket 120 are coated on the edge of the diaphragm 130, that is, the edge of the diaphragm 130 is wrapped by the first sealing gasket 110 and the second sealing gasket 120. This coating design allows the edge of the diaphragm 130 to be completely covered by the first sealing gasket 110 and the second sealing gasket 120 to form a complete sealing layer. Under high pressure, this coating design can effectively prevent the electrolyte from leaking from the edge of the diaphragm 130. At the same time, the edge of the diaphragm 130 is limited by the second step surface 116 to ensure that it remains stable under high pressure and prevent displacement. This design not only provides double protection, but also ensures the sealing performance of the second sealing gasket 120 under high pressure.

[0035] The one side of the first sealing gasket 110 and the second sealing gasket 120 that faces each other is a step structure, which includes a first step surface 115 and a second step surface 116, wherein the first step surface 115 is located on the outside of the second step surface 116; the first step surface 115 protrudes from the second step surface 116; the second step surface 116 is a plane and is used to limit the diaphragm 130; the other side of the second sealing gasket 120 and the first sealing gasket 110 that faces each other is a plane.

[0036] It can be understood that, in some embodiments, the side of the first sealing gasket 110 facing the second sealing gasket 120 is stepped, and the side of the second sealing gasket 120 facing the first sealing gasket 110 is flat. In other embodiments, the side of the second sealing gasket 120 facing the first sealing gasket 110 is stepped, and the side of the first sealing gasket 110 facing the second sealing gasket 120 is flat.

[0037] In the above structure, the first stepped surface 115 forms a protective "fence" to ensure that the edge of the diaphragm 130 is not directly exposed to the outside under high pressure, thereby preventing the edge of the diaphragm 130 from being deformed or displaced due to high pressure. In addition, the first stepped surface 115 also plays a role in dispersing pressure, so that the high pressure generated inside can be evenly distributed on the first stepped surface 115, rather than concentrated on a certain part of the diaphragm 130, thereby preventing the diaphragm 130 from being damaged due to excessive local force.

[0038] The side of the second sealing gasket 120 facing the first sealing gasket 110 is designed to be flat, and the main purpose of this design is to prevent the diaphragm 130 from being damaged under high pressure. The flat surface can prevent the diaphragm 130 from being rubbed or scratched when it contacts the second sealing gasket 120, especially when the pressure inside the electrolytic cell 200 is high, this protection is particularly important. In addition, the flat design also helps to adjust the position of the diaphragm 130 more easily during the assembly process, ensuring that the diaphragm 130 can be evenly distributed in the entire sealing assembly 100, thereby improving the sealing effect.

[0039] The present invention can maintain good sealing performance under high pressure conditions and effectively prevent leakage of electrolyte by protecting the edge of the diaphragm 130 and dispersing the pressure through the stepped structure of the first sealing gasket 110 and protecting the diaphragm 130 through the planar design of the second sealing gasket 120. This design not only improves the working efficiency of the electrolytic cell 200, but also reduces the cost of back-end separation and purification caused by poor sealing, ensuring the stable operation of the entire system.

[0040] Specifically, in some other possible embodiments, the protruding portion of the first stepped surface 115 can be set as a sealing tooth 114, and the plurality of sealing teeth 114 are arranged in sequence along the width direction of the first sealing gasket 110, that is, the plurality of sealing teeth 114 are arranged in sequence from the inside to the outside. If the thickness of the first sealing gasket 110 is marked as h, and the height of the sealing teeth 114 on the first stepped surface 115 is marked as h1, then h1 < 1 / 3h; if the ring width of the first sealing gasket 110 is marked as w, and the width of the second stepped surface 116 is marked as w1, then w1 ≤ 1 / 2w.

[0041] In this embodiment, these sealing teeth 114 are arranged in sequence from the inside to the outside, and each sealing tooth 114 can form an independent sealing portion at the edge of the diaphragm 130. When high pressure is generated inside the electrolytic cell 200, these sealing teeth 114 can gradually press the edge of the diaphragm 130, and through the superposition effect of the multi-layer sealing portion, it is ensured that the edge of the diaphragm 130 can still remain tightly fitted under high pressure, effectively preventing the electrolyte from leaking from the edge. This design of multi-layer sealing teeth 114 not only improves the reliability of the seal, but also ensures that when a certain sealing tooth 114 is slightly worn or damaged, the other sealing teeth 114 can still continue to function, thereby ensuring the long-term stability and durability of the entire sealing assembly 100.

[0042] In addition, the design of the sealing teeth 114 being arranged sequentially from the inside to the outside can also better disperse the internal pressure. Each sealing tooth 114 can evenly transmit the pressure, preventing the edge of the diaphragm 130 from being deformed or damaged due to excessive local force. This design ensures that the diaphragm 130 remains stable under high pressure and reduces the risk of sealing failure caused by local pressure concentration.

[0043] Reference Figure 2 In some embodiments of the present invention, sealing teeth 114 are provided on the surfaces of the first sealing gasket 110 and the second sealing gasket 120 which are opposite to each other.

[0044] In actual use, the side of the first sealing gasket 110 and the second sealing gasket 120 that are away from each other needs to be press-fitted with different middle frames 210 to form a whole. In this embodiment, by providing sealing teeth 114 on the side of the first sealing gasket 110 and the second sealing gasket 120 that are away from each other, the contact area between the first sealing gasket 110, the second sealing gasket 120 and the middle frame 210 can be significantly increased, making the combination between the sealing gasket and the middle frame 210 more secure.

[0045] In addition, each sealing tooth 114 forms a plurality of tiny sealing points by closely contacting the surface of the middle frame 210. These tiny sealing points can effectively prevent the electrolyte from leaking from the gap between the sealing gasket and the middle frame 210, especially in a high-pressure environment, the effect of this multi-point sealing is more significant.

[0046] Furthermore, the design of the sealing teeth 114 can also increase the friction between the sealing gasket and the middle frame 210, thereby ensuring that the sealing gasket will not be displaced due to external pressure during the press-fitting process. This enhanced friction not only helps to maintain the fixed position of the sealing gasket, but also reduces loosening caused by vibration or other external factors, further improving the stability and reliability of the sealing assembly 100.

[0047] Reference Figure 3In some embodiments of the present invention, the first sealing gasket 110 and the second sealing gasket 120 both include a first insulating layer 111 and a second insulating layer 113, and a metal wire layer 112 is provided between the first insulating layer 111 and the second insulating layer 113. Specifically, the first insulating layer 111, the metal wire layer 112 and the second insulating layer 113 can be vulcanized and compounded in a mold, and a corresponding structure can be obtained through the mold, and the material of the first insulating layer 111 and the second insulating layer 113 can be rubber. In this embodiment, the first sealing gasket 110 and the second sealing gasket 120 are combined through a multi-layer structure, which not only ensures the electrical insulation performance of the sealing assembly 100, but also enhances its mechanical strength, thereby significantly improving the comprehensive performance and reliability of the sealing assembly 100 under high pressure environments.

[0048] Specifically, in the structural design of the first sealing gasket 110 and the second sealing gasket 120, the first insulating layer 111 and the second insulating layer 113 are both made of rubber. Rubber has excellent elasticity and sealing properties, which can ensure that the sealing gasket maintains a tight fit under high pressure and effectively prevents leakage of the electrolyte. At the same time, the rubber material also has good chemical corrosion resistance and can be used for a long time in the strong acid or strong alkali environment of the electrolytic cell 200 without aging or damage.

[0049] The metal wire layer 112 disposed between the two layers of rubber material not only improves the mechanical strength of the sealing gasket, making it less likely to deform or break under high pressure, but also enhances the thermal conductivity of the sealing gasket. During the electrolysis process, a large amount of heat will be generated inside the electrolytic cell 200, and the metal wire layer 112 can effectively conduct this heat away to avoid damage to the sealing gasket due to local overheating. In addition, the metal wire layer 112 can also provide a certain electromagnetic shielding effect, reduce the impact of external electromagnetic interference on the electrolysis process, and ensure the stable operation of the electrolytic cell 200.

[0050] Reference Figure 3 In some embodiments of the present invention, the metal wire layer 112 is a mesh structure. The mesh structure of the metal wire layer 112 uses a 304 stainless steel wire mesh with a wire diameter of 20-40 meshes and a wire diameter of 0.2-0.4 or a corrosion-resistant metal wire mesh such as nickel or titanium. The metal wire mesh is ≤2mm from the boundary and completely covers the inside of the first insulating layer 111 and the second insulating layer 113.

[0051] It should be noted that the mesh structure of the metal wire layer 112 can be a woven mesh or a stamped mesh. The woven mesh can be formed by interweaving metal wires through warp and weft to form a continuous mesh structure. The metal wire layer 112 of this mesh structure has high flexibility and ductility. The high flexibility of the woven mesh enables the sealing gasket to deform with the shape when subjected to external pressure, ensuring a close fit with the middle frame 210 of the electrolytic cell 200, thereby improving the sealing effect. In addition, the ductility of the metal wire layer 112 of the woven mesh can also absorb and disperse external shocks and vibrations, reduce fatigue damage to the sealing gasket, and extend its service life. This structure performs particularly well in the electrolytic cell 200 that needs to be frequently disassembled or works in a dynamic environment, and can ensure that the sealing gasket can still maintain good sealing performance after multiple uses. In other possible embodiments, when the specific structure of the mesh of the metal wire layer 112 is a woven mesh, some non-metallic materials can also be woven into the metal wire layer 112.

[0052] The stamped grid can be a grid structure formed by a metal sheet through a stamping process. The metal wire layer 112 of this grid structure has high strength and rigidity. The high rigidity of the stamped grid can provide stronger support under high pressure environment, prevent the sealing gasket from being deformed or damaged under high pressure, and ensure the reliability of the seal. The high rigidity of the stamped grid can also effectively transfer and disperse the heat generated inside, avoiding material aging or damage caused by local overheating.

[0053] Reference Figure 2 In some embodiments of the present invention, a gap is provided between the edge of the diaphragm 130 and the first step surface 115. Specifically, if the distance between the edge of the diaphragm 130 and the first step surface 115 is represented as L, then L is 0.1 mm-5 mm.

[0054] In this embodiment, a gap is provided between the edge of the diaphragm 130 and the first stepped surface 115. The design of this gap allows the diaphragm 130 to have a certain amount of movement space when subjected to internal pressure. When high pressure is generated inside the electrolytic cell 200, the diaphragm 130 will be pushed outward. If there is no appropriate gap, the diaphragm 130 may be over-extruded, resulting in deformation or damage. By providing a gap, the diaphragm 130 can freely expand and contract within a certain range, thereby avoiding the risk of excessive extrusion.

[0055] In addition, the existence of the gap also helps to reduce the friction between the diaphragm 130 and the first stepped surface 115. Under high pressure, if the diaphragm 130 is in direct contact with the first stepped surface 115, the friction may cause wear on the surface of the diaphragm 130, thereby affecting the sealing effect. By setting the gap, a certain distance is maintained between the diaphragm 130 and the first stepped surface 115, reducing friction and extending the service life of the diaphragm 130.

[0056] Furthermore, the design of the gap can also improve the adaptability of the sealing assembly 100. In actual applications, the pressure in the electrolytic cell 200 may fluctuate, and the size and shape of the diaphragm 130 may also change due to temperature changes. By setting the gap, the sealing assembly 100 can better adapt to these changes and ensure that good sealing performance can be maintained under different working conditions.

[0057] Reference Figure 2 In some embodiments of the present invention, the tooth shape of the sealing tooth 114 includes a triangle and a trapezoid.

[0058] In this embodiment, the main advantage of the design of the triangular sealing teeth 114 is that it can provide a strong local pressing force. When high pressure is generated inside the electrolytic cell 200, the sharp apex of the triangular sealing teeth 114 can first contact and press the edge of the diaphragm 130 to form a preliminary sealing point. As the pressure increases, the two sides of the sealing teeth 114 gradually press the diaphragm 130 to ensure that the edge of the diaphragm 130 can still remain tightly fitted under high pressure. This gradual pressing effect can effectively prevent the electrolyte from leaking from the edge and improve the reliability of the seal.

[0059] In addition, the sharp apex of the triangular sealing tooth 114 can also form a tiny depression on the surface of the diaphragm 130, increasing the contact area and friction between the diaphragm 130 and the sealing tooth 114. Such increased contact area and friction help to further enhance the sealing effect and reduce the risk of sealing failure due to vibration or other external factors. However, it should be noted that the sharp apex of the triangular sealing tooth 114 may cause a certain amount of wear to the diaphragm 130, so in order to balance the sealing effect and the service life of the diaphragm 130 during design, an arc-shaped chamfer can be set at the top of the triangular sealing tooth 114.

[0060] The design feature of the trapezoidal sealing teeth 114 is that they are narrow at the top and wide at the bottom. The main advantage of this design is that it can provide uniform compression force distribution. When high pressure is generated inside the electrolytic cell 200, the wide bottom of the trapezoidal sealing teeth 114 can evenly transmit pressure to prevent the edge of the diaphragm 130 from being deformed or damaged due to excessive local force. This uniform compression force distribution not only improves the reliability of the seal, but also extends the service life of the diaphragm 130.

[0061] In addition, the wide bottom design of the trapezoidal sealing teeth 114 can also increase the contact area with the diaphragm 130, improving the stability and reliability of the seal. Under high pressure, the trapezoidal sealing teeth 114 can better adapt to the deformation of the diaphragm 130, ensuring a tight fit between the sealing teeth 114 and the diaphragm 130. This design can also reduce the friction between the diaphragm 130 and the sealing teeth 114, reduce the wear of the diaphragm 130, and further improve the durability of the sealing assembly 100.

[0062] It should be noted that any of the above tooth shapes are within the protection scope of the present invention. In practical applications, it is only necessary to select a suitable sealing tooth 114 shape or use a combination of multiple tooth shapes according to specific working conditions and requirements.

[0063] Reference Figures 4 to 6 The present invention further provides an electrolytic cell 200, which includes at least one sealing assembly 100 according to any one of the above embodiments and at least two middle frames 210, wherein the sealing assembly 100 and the middle frames 210 are arranged alternately.

[0064] Specifically, a partition 250 is provided in the middle of the middle frame 210, an anode plate is provided on one side of the partition 250, and a cathode plate is designed on the other side. By arranging the sealing assembly 100 on one side of the middle frame 210, a small chamber can be formed between the diaphragm 130 and the partition 250. Multiple sealing assemblies 100 and the middle frame 210 are arranged alternately and then pressed together by extrusion to form multiple small chambers. It should be noted that the polarities of the electrodes on the opposite sides of two adjacent partitions 250 are opposite.

[0065] Reference Figure 2 In some embodiments of the present invention, a side of the middle frame 210 facing the sealing assembly 100 is provided with an anti-skid layer 220. It is understandable that both sides of the middle frame 210 are provided with an anti-skid layer 220, while the outer surface of the middle frame 210 located at the outermost side may not be provided with an anti-skid layer 220. During specific installation, the first sealing gasket 110 or the second sealing gasket 120 is pressed onto the surface of the middle frame 210.

[0066] In some specific embodiments, the anti-slip layer 220 can be provided by adding a mesh pattern to the outer surface of the middle frame 210. The mesh pattern can be formed on the surface of the metal plate by mechanical processing or chemical treatment. Mechanical processing methods include rolling, stamping or engraving, etc., which can form regular or irregular mesh patterns on the surface of the metal plate. For example, through a rolling process, the metal plate can be stamped by a roller with a mesh pattern, so as to form a uniform mesh pattern on the surface of the middle frame 210. This method is suitable for large-scale production and can efficiently form a stable mesh structure on the surface of the middle frame 210.

[0067] Secondly, the anti-skid layer 220 can also be provided by chemical treatment, for example, by forming a reticulation on the surface of the metal plate through an etching process. The etching process generally involves immersing the metal plate in a specific chemical solution, and forming a desired reticulation pattern on the surface through a chemical reaction. This method can accurately control the depth and shape of the reticulation, and is suitable for occasions requiring high-precision reticulation. The reticulation structure formed by chemical etching has high consistency and uniformity, and can provide stable anti-skid performance.

[0068] By providing a mesh structure on the surface of the middle frame 210, the friction force of the outer surface of the middle frame 210 can be significantly increased. The uneven surface of the mesh can form more contact points with the contact surface of the electrolytic cell 200, increase the friction force, and thus prevent the middle frame 210 from sliding or displacing under high pressure and high temperature. This increased friction force not only improves the fixing effect of the middle frame 210, but also reduces the looseness caused by external vibration or impact, ensuring the stability and reliability of the sealing assembly 100.

[0069] Reference Figure 7 and Figure 8 The present invention also provides a flipping table, which is used for the electrolytic cell 200 of any of the above embodiments to realize the pre-installation of the electrolytic cell 200. The flipping table includes a support frame 310, a rotating frame 320 and a locking member. The rotating frame 320 is rotatably arranged on the support frame 310. The rotating frame 320 is used to limit the electrolytic cell 200 and is used to switch between the first position and the second position. The locking member is arranged between the support frame 310 and the rotating frame 320, and is used to fix the rotating frame 320 to the support frame 310. The support frame 310 includes a base 311, at least two first limiting rods 312 and a second limiting rod 313. The two first limiting rods 312 are arranged at intervals on the base 311. The first limiting rod 312 is used to fix the rotating frame 320 on a vertical plane. The second limiting rod 313 is arranged on the first limiting rod 312 in a one-to-one correspondence, and the second limiting rod 313 is used to fix the rotating frame 320 on a horizontal plane.

[0070] Specifically, in order to better install with 300, both sides of the middle frame 210 are provided with a limit block 230 and a first limit hole 240, and the limit block 230 is located at the top of the middle frame 210, and the first limit hole 240 is located at the bottom of the middle frame 210. The shape of the limit block 230 is adapted to the limit groove 323, so that the electrolytic cell 200 can be better limited on 300.

[0071] The base 311 is a rectangular frame structure, and its function is to bear. The first limiting rod 312 is a rectangular parallelepiped structure, and two first limiting rods 312 are provided. The two first limiting rods 312 are respectively vertically fixedly installed on the top surfaces of the two side frames, and the bottom of the first limiting rod 312 is provided with a second limiting hole 314. The second limiting rod 313 is horizontally fixedly installed on one side of the top of the first limiting rod 312, and the second limiting rod 313 is provided with a third limiting hole 315. The rotating frame 320 is a U-shaped mechanism, and the two ends of its opening are respectively rotatably connected to the top ends of the two first limiting rods 312. The rotating frame 320 is provided with a fourth limiting hole 321 and a fifth limiting hole 322.

[0072] When the electrolytic cell 200 needs to be pre-set, the rotating frame 320 is first placed in a vertical state, at which time the second limiting hole 314 and the fourth limiting hole 321 are aligned, and the positioning pin can be passed through the second limiting hole 314 and the fourth limiting hole 321, so that the rotating frame 320 is fixed on the first limiting rod 312, so that the rotating frame 320 remains in a vertical state, and then the limiting block 230 on the middle frame 210 is clamped on the limiting groove 323. Then the positioning pin is removed, and the rotating frame 320 is rotated to make it in a horizontal state, at which time the fifth limiting hole 322 is aligned with the third limiting hole 315, and then the positioning pin is passed through the fifth limiting hole 322 and the third limiting hole 315, so that the middle frame 210 remains in a horizontal state, and then the first sealing gasket 110 or the second sealing gasket 120 is installed on the middle frame 210, and finally the diaphragm 130 is installed on the first sealing gasket 110 or the second sealing gasket 120. In this way, the first sealing gasket 110 or the second sealing gasket 120 can be accurately installed with the diaphragm 130. After the electrolytic cell 200 is assembled, the electrolytic cell 200 can be turned over to a vertical state.
