It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] In order to solve the technical problem of how to form a clamping structure without external pressure between the plate frame and the electrode plate, the present utility model provides a clamping structure of the plate frame and the electrode plate, which can realize the formation of a clamping structure without external pressure between the plate frame and the electrode plate.

[0031] It should be noted that the clamping structure of the plate frame and the electrode plate described in the present utility model is applicable to but not limited to electrolytic cells, etc. For the convenience of description, in the present utility model, only the case where the clamping structure of the plate frame and the electrode plate is applied to an electrolytic cell is taken as an example for description, and the principle of applying the clamping structure of the plate frame and the electrode plate to other types of equipment is essentially the same as that applied to an electrolytic cell, and will not be elaborated here one by one.

[0032] Please refer to Figure 1 , Figure 1The figure is a schematic structural diagram of a clamping structure between a plate frame and a plate electrode in an embodiment of the present utility model. The clamping structure between the plate frame and the plate electrode includes a plate electrode member 1, a plate frame member 2, a sealing ring 3, and a fastening portion 4. Under the basic combination of the clamping structure, the two plate frame members 2 are respectively arranged on both sides of a plate electrode member 1. Among them, the plate electrode member 1 can be a cathode plate or an anode plate. The sealing ring 3 is embedded on the end faces of the plate frame member 2. When the plate frame member 2 is pressed onto the end face of the plate electrode member 1, the gap is sealed by pressing the sealing ring 3. The fastening portion 4 is arranged on both sides of the plate frame member 2, specifically the front side and the rear side. The fastening portion 4 is an extended portion of the plate frame member 2 towards both sides. The fastening portion 4 is used to fasten the two plate frame members 2 and clamp the sealing ring 3. In this way, a plate electrode member 1 is clamped between two adjacent plate frame members 2, and there is no need to apply additional external force for pressing and sealing. The fastening portion 4 provided on the plate frame member 2 can form a sufficient sealing effect, eliminating the need for an additional pressing device and reducing the occupied space of the entire device. Specifically, the fastening portion 4 includes a base 41, a pushing block 42, and a fastening part 43. The base 41 is arranged on the side surface of the plate frame member 2. The base 41 is a part extended from the plate frame member 2. A fastening groove 44 is opened on one side of the base 41 near one end face. The fastening groove 44 penetrates through the top and bottom of the plate frame member 2, allowing the fastening part 43 to be inserted from bottom to top and the fastening part 43 to be inserted from top to bottom. The pushing block 42 is arranged inside the fastening groove 44. The fastening part 43 is arranged on one side of the base 41 near the other end face, and is used to be inserted into the corresponding fastening groove 44 on the adjacent plate frame member 2 and abut against the pushing block 42 inside it, pressing the sealing ring 3 onto the end face of the plate electrode member 1. By inserting the fastening part 43 into the fastening groove 44 and abutting the fastening part 43 against the pushing block 42, when abutting, the sealing ring 3 is pressed, prompting the plate frame member 2 and the plate electrode member 1 to be pressed tightly to form a seal.

[0033] Further, please refer to Figure 2 , the shape of the fastening part 43 is L-shaped, and the shape of the corresponding fastening groove 44 is also L-shaped, forming a hook-shaped insertion structure. Under the abutment with the pushing block 42, the sealing ring 3 is extruded to form a fastening.

[0034] In one of the embodiments, please refer to Figure 1 、 Figure 2 and Figure 3, the pushing block 42 has a flat portion 421 and a curved surface portion 422. The curved surface portion 422 is provided at the top and bottom of the flat portion 421 and has a curved surface that gradually contracts starting from the flat portion 421. That is, the outer diameters of both ends of the pushing block 42 are small, and the outer diameter gradually increases during the process of gradually moving towards the middle section. During the process of the fastener 43 being pushed down or up, it has the effect of gradually pushing to press the plate frame member 2 and the electrode plate member 1 tightly. Among them, the fastener 43 has a position state of being internally buckled with the curved surface portion 422, a position state of being internally buckled with the flat portion 421, and a position state of disengaging from the buckle groove 44. When it is in the position state of being internally buckled with the flat portion 421, it is in the position of tightly clamping the electrode plate member 1.

[0035] In this embodiment, the fastener 43 is inserted from bottom to top or the fastener 43 is inserted from top to bottom. Under the guidance of the curved surface portion 422, the pushing of the fastener 43 along the inclined surface causes the plate frame member 2 and the electrode plate member 1 to be gradually pressed tightly.

[0036] In one of the embodiments, please refer to Figure 3 , an outwardly convex elastic layer 423 is provided on the flat portion 421. When the fastener 43 is pressed onto the flat portion 421, a reaction force can be provided by the elastic layer 423 being extruded, making the clamping between the plate frame member 2 and the electrode plate member 1 tighter.

[0037] In one of the embodiments, please refer to Figure 5 , convex edges 201 are provided on both sides of one of the adjacent plate frame members 2 for splitting. By pushing the outwardly convex convex edges 201, it is convenient to apply a force to the plate frame member 2 to split the two plate frame members 2.

[0038] In one of the embodiments, please refer to Figure 4 , in order to perform pre-insertion positioning on the electrode plate member 1 during clamping, a limiting frame 202 is provided at the top of the plate frame member 2. The limiting frame 202 is U-shaped, and the electrode plate member 1 is inserted inside the U-shaped limiting frame 202. The top of the electrode plate member 1 has a conductive bus bar 101, and the bottom of the conductive bus bar 101 abuts against the top of the limiting frame 202, thereby forming insertion positioning, which is convenient for forming a clamping structure for the electrode plate member 1 after the subsequent two limiting frames 202 are buckled.

[0039] In one of the embodiments, please refer to Figure 4 , in order to facilitate the installation and positioning of the sealing ring 3, an annular groove 203 is opened on the end face of the plate frame member 2, and the sealing ring 3 is embedded inside the annular groove 203.

[0040] In another embodiment, please refer to Figure 6, the shape of the buckle 43 is T-shaped, and the shape of the corresponding buckle groove 44 is also T-shaped. Compared with the L-shaped buckle 43, there are two pushing blocks 42 in the buckle groove 44, which are respectively located on both sides of the T-shape and are both in contact with the T-shaped buckle. Compared with the L-shaped buckle 43, the buckle structure is more balanced.

[0041] For a better understanding of the present invention, the following is a detailed description of the technical solution of the present invention in conjunction with Figures 1 to 4 Insert the electrode plate member 1 into the limiting frame 202 of a frame member 2, and then insert the buckle 43 of the other frame member 2 from bottom to top into the buckle groove 44 on the previous frame member 2, and align the two frame members 2, so as to complete the clamping of the electrode plate member 1. Then, stack the limiting frames 202 and the electrode plate members 1 in sequence to form a plurality of sealed chambers, which constitute the main part of the electrolytic cell. Without an additional pressing mechanism, the clamping and sealing effect of the electrode plates can be achieved by using the buckling part 4.

[0042] In a second aspect, the present invention also provides an electrolytic cell, including the frame and electrode plate clamping structure described in any one of the above embodiments. The number of the frame and electrode plate clamping structures is multiple, and the multiple frame and electrode plate clamping structures are sequentially buckled and connected through the buckling part 4. The electrode plate member 1 is clamped between adjacent frame members 2. The electrode plate members 1 on the multiple buckled and connected frame and electrode plate clamping structures are respectively a cathode plate and an anode plate, and are arranged at intervals in sequence; it further includes head and tail plates 5. The number of the head and tail plates 5 is two, and they are respectively arranged at the head end and the tail end of the multiple buckled and connected frame and electrode plate clamping structures, so as to form a complete electrolytic cell.

[0043] It can be understood that the number of the frame and electrode plate clamping structures is multiple, which is set according to actual needs. The main purpose is to clamp the cathode plate and the anode plate and finally combine them into an electrolytic cell.

[0044] It should be noted that after the frame and the electrode plate are clamped, a plurality of chambers are formed. Communication holes are provided on both the frame and the electrode plate to penetrate each chamber to supply the electrolyte to flow through. The above is the prior art and will not be elaborated here.

[0045] Furthermore, a groove body matching the buckle 43 is provided on one of the head and tail plates 5, and a fastener matching the buckle groove 44 is provided on the other head and tail plate 5. The groove body is the same as the buckle groove 44, and the fastener is the same as the buckle 43, so as to match the buckling structure between the frame members 2.
