Description

Technical Field

[0001] This invention relates to the field of electrode design, and in particular to an electrode frame and electrode assembly and a method for processing thereof. Background Technology

[0002] In the existing technology, the electrode plate is directly injection molded into the plastic electrode frame. However, due to the area requirements of the electrode plate, a bulge will appear in the middle under the design size. This is due to the shrinkage effect of the plastic. The metal insert of the electrode plate is subjected to centripetal extrusion force, which causes the electrode plate to deform. In severe cases, the height of the bulge of the electrode plate exceeds the surface of the electrode frame, making it impossible to use normally.

[0003] Therefore, there is an urgent need for an electrode frame and electrode plate assembly and its processing method, which would help solve the technical problem of the lack of an electrode plate injection molding deformation method in the existing technology. Summary of the Invention

[0004] In one embodiment, the present invention provides an electrode frame and electrode plate assembly. In addition to being formed by a plastic outer frame and a first electrode plate, a portion of the electrode plate is also fixed separately, so that the injection molding does not affect the deformation of the second electrode plate. This helps to solve the technical problem of the lack of an electrode plate injection molding deformation method in the prior art.

[0006] The electrode frame includes a plastic outer frame and a first electrode plate, with one edge of the first electrode plate embedded in the plastic outer frame;

[0009] In one embodiment, the second electrode plate is a disk structure, and the outer edge of the disk structure is fixedly connected to the inner edge of the first electrode plate.

[0010] In one embodiment, the second electrode plate is fixed to the first electrode plate by welding on both sides.

[0011] In one embodiment, nipple-like protrusions are provided on the bidirectional side surfaces of the second electrode plate.

[0012] In one embodiment, the plastic outer frame is provided with flow channels for alkali solution and gas, the flow channels penetrating from one side of the plastic outer frame and passing through the plastic outer frame and the first electrode plate.

[0013] In one embodiment, the electrode frame and electrode plate assembly are applied to an electrolytic cell.

[0016] A second electrode plate is connected at the edge on the other side of the first electrode plate.

[0030] In the design of this invention, the plastic outer frame 11 and the first electrode plate 12 still adopt the embedded structure of the prior art. On the one hand, this ensures structural stability; on the other hand, compared with metal electrode frames, plastic materials have the advantages of being able to be integrally molded, lightweight, low-cost, and corrosion-resistant. Therefore, the plastic outer frame has great advantages. However, the problem of electrode plate deformation during injection molding is the most important issue that this invention aims to solve.

[0031] Figure 1 This is a front view of the electrode frame and electrode plate assembly in one embodiment of the present invention. Figure 2 This is a side view of the pole frame and pole plate assembly in another embodiment of the present invention. Figure 3 This is a schematic diagram of a separate structure for the pole frame and pole plate assembly in another embodiment of the present invention. Figure 1 and Figure 2 ,as well as Figure 3 As shown, in one embodiment, the present invention provides an electrode frame and electrode plate assembly, the electrode frame and electrode plate assembly including an electrode frame 1 and a second electrode plate 2;

[0032] The electrode frame 1 further includes a plastic outer frame 11 and a first electrode plate 12, with one edge of the first electrode plate 12 embedded in the plastic outer frame 11;

[0033] After the edge of the second electrode plate 2 is aligned with the edge of the first electrode plate 12, it is fixed.

[0034] This embodiment provides a specific structure for an electrode frame and electrode plate assembly. The electrode plate is divided into two parts: a first electrode plate 12 and a second electrode plate 2. The first electrode plate 12 ensures the relative positional relationship and structure between the plastic outer frame 11 and the electrode plate. The second electrode plate 2 participates in the injection molding process to ensure the overall flatness of the electrode plate portion, ultimately connecting the second electrode plate 2 and the electrode frame 1. This maintains the original structural advantages while avoiding the problem of excessive overall deformation of the electrode plate, helping to solve the technical problem of lacking an electrode plate injection molding deformation method in the prior art.

[0035] In one embodiment, the plastic outer frame 11 and the first electrode plate 12 are annular structures, with the first electrode plate 12 being fitted inside the plastic outer frame 11, and the outer edge of the first electrode plate 12 being embedded inside the plastic outer frame 11.

[0036] This embodiment provides a specific structure of a plastic outer frame 11 and a first electrode plate 12. It is precisely because the previous electrode plate adopted a ring structure that it bulged towards the center. This is because in the prior art, the electrode plate would be affected by stress and extend the material towards the center, so the center of the circular structure would bulge. However, in this embodiment, since the center of the ring structure is hollow, even if the material extends towards the center, there will be no concentrated strain.

[0037] In one embodiment, the second electrode plate 2 is a disk structure, and the outer edge of the disk structure is fixedly connected to the inner edge of the first electrode plate 12.

[0038] This embodiment provides a specific structure of the second electrode plate 2 and discloses the connection relationship between the disk structure and the first electrode plate 12. The outer diameter of the disk structure should be consistent with the inner diameter of the first electrode plate 12. Although the annular structure may also have a certain material extension towards the center, since the second electrode plate 2 is subsequently welded onto the first electrode plate 12, a certain amount of space deformation can be left to match the inner edge of the deformed first electrode plate 12.

[0039] In one embodiment, the second electrode plate 2 is fixed to the first electrode plate 12 by welding on both sides.

[0040] This embodiment provides a specific implementation method for welding and fixing. Preferably, a method for fixing the second electrode plate 2 to the first electrode plate 12 is provided.

[0041] In one embodiment, nipple-like protrusions 21 are provided on the bidirectional side surfaces of the second electrode plate 12.

[0042] In this embodiment, the second electrode plate 12 has nipple-like protrusions 21 on both sides to facilitate better electrochemical reactions during the subsequent electrolytic reaction in the electrolytic cell.

[0043] In one embodiment, the plastic outer frame 11 is provided with flow channels 111 for alkaline solution and gas, and the flow channels 111 penetrate from one side of the plastic outer frame 11 and the first electrode plate 12.

[0044] This embodiment provides a specific structure with flow channel holes 111 through which alkaline fluid flows between the electrode plate and the plastic frame 11. The flow channel holes 111 for both alkaline solution and gas are structural features of the electrode frame and electrode plate assembly that require coordination with other equipment designs.

[0045] In one embodiment, the electrode frame and electrode plate assembly are applied to an electrolytic cell.

[0046] This embodiment provides a specific application scenario for the aforementioned pole frame and pole plate assembly.

[0047] Figure 4 This is a schematic flowchart illustrating a processing method for an electrode frame and electrode plate assembly according to another embodiment of the present invention. Figure 4 As shown, in one embodiment, the present invention also provides a method for processing an electrode frame and electrode plate assembly, the processing method comprising:

[0048] S101, a plastic outer frame 11 is formed by injection molding on the first electrode plate 12 so that one side edge of the first electrode plate 12 is embedded in the plastic outer frame 11 to obtain the electrode frame 1.

[0049] This step provides a specific process for manufacturing the first electrode plate 12 and the plastic outer frame 11.

[0050] S102, the second electrode plate 2 is connected at the edge on the other side of the first electrode plate 12.

[0051] This step provides a specific procedure for setting the second electrode plate 2 on the first electrode plate 12.

[0052] This embodiment provides a method for processing an electrode frame and electrode plate assembly. First, the first electrode plate 12 provides support for the plastic outer frame 11. Figure 2 As shown, the edge of the first electrode plate 12 should be embedded in the middle part of the plastic outer frame 11, and then the first electrode plate 12 and the second electrode plate 2 are connected and welded together. The welding here is done on both sides.

[0053] In one embodiment, after the step of injection molding a plastic outer frame 11 onto the first electrode plate 12 to embed one side edge of the first electrode plate 12 into the plastic outer frame 11 to obtain the electrode frame 1, the method further includes:

[0054] The flow channel hole 111 is obtained by secondary processing of the pole frame 1 or by integral injection molding.

[0055] This embodiment provides a different implementation method based on the processing of flow channel holes 111. This is also an advantage of plastic one-piece molding technology. After one-piece molding, secondary processing of the plastic outer frame 11 can also achieve the purpose of processing flow channel holes 111.

[0056] In one embodiment, before the step of connecting the second electrode 2 at the edge on the other side of the first electrode 12, the method further includes:

[0057] The flatness of the second electrode plate 12 is adjusted.

[0058] This embodiment provides a specific implementation method for adjusting the flatness of the second electrode plate 12 before welding to meet predetermined design requirements. Further adjustments are made to the flatness of the second electrode plate 2.

The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
