DETAILED DESCRIPTION

[0016] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2As shown, the electrolytic cell electrode plate clamping device provided in the embodiment of the present application has a structure including symmetrical anode end plates 1 and cathode ends, and a plurality of tensioning mechanisms 3 connecting the anode end plates 1 and the cathode end plates 2, wherein the anode end plate 1 includes a rectangular frame 11, and a plurality of connectors 12 arranged and welded on the upper end surface and the lower end surface of the frame, wherein the rectangular frame 11 is provided with a through hole 101, and the connector 12 includes a No. 1 portion 121 located on the outer side of the frame end surface and a protrusion 122 integrally formed with the No. 1 portion 121 and extending into the through hole 101, wherein the protrusion 122 forms a clearance fit with the through hole 101, and the No. 1 portion 121 is welded to the frame.

[0018] In actual use, the anode end plate 1 and the cathode end plate 2 are tightened by the tightening mechanism 3, and the electrode plates for electrolysis are clamped by the anode end plate 1 and the cathode end plate 2. During the tightening process of the tightening mechanism 3, the connector 12 is subjected to tension. The cooperation of the protrusion 122 with the through hole 101 will limit the tearing of the connector 12 along the direction of the tension.

[0019] In the above design, by setting the protrusion 122 to cooperate with the rectangular frame 11 provided with the through hole 101, the service life and safety of the anode end plate 1 and the cathode end plate 2 can be further enhanced through the limitation between the protrusion 122 and the through hole 101, and during the manufacturing process of the anode end plate 1 and the cathode end plate 2, the positioning accuracy and production efficiency can be improved through the cooperation between the protrusion 122 and the through hole 101.

[0020] Specifically: Figure 2 As shown, the No. 1 portion 121 includes a No. 1 plate 1211, a No. 2 plate 1212 and a No. 3 plate 1213 symmetrically arranged on both sides of the No. 1 plate 1211, the protrusion 122 includes a No. 2 protrusion 1221 arranged on the lower end surface of the No. 2 plate 1212 and a No. 3 protrusion 1222 arranged on the lower end surface of the No. 3 plate 1213, and the No. 1 plate 1211 is provided with a through hole through which the tensioning mechanism 3 passes.

[0021] In actual use, the tensioning mechanism 3 passes through the No. 1 plate 1211, and the No. 2 plate 1212 and the No. 3 plate 1213 are welded with the rectangular frame 11 to form a weld along the extension direction of the tensioning mechanism 3. When the tensioning mechanism 3 is tightened, the No. 2 plate 1212 and the No. 3 plate 1213 will be subjected to tension, and the No. 2 protrusion 1221 and the No. 3 protrusion 1222 are clamped with the through hole 101 on the rectangular tube, which can prevent cracks from occurring in the welds between the No. 2 plate 1212 and the rectangular frame 11, and between the No. 3 plate 1213 and the rectangular frame 11.

[0022] In the above design, the structural design and specific implementation of the connecting member 12 can effectively achieve the positioning welding of the rectangular frame 11 and the firmness after welding.

[0023] Specifically: Figure 2 and Figure 3 As shown, the tensioning mechanism 3 includes a bald screw 31, an insulating sleeve 32 arranged on the bald screw 31, and a No. 1 fastener 33 and a No. 2 fastener 34 respectively arranged at both ends of the bald screw 31, and the two ends of the insulating sleeve 32 extend out of the anode end plate 1 and the cathode end plate 2 respectively, the No. 1 fastener 33 is used to limit one end of the bald screw 31 and the anode end plate 1, and the No. 2 fastener 34 is used to limit the other end of the bald screw 31 and the cathode end plate 2.

[0024] In actual use, insulation protection during the electrolysis process is achieved through the insulating sleeve 32. When the tensioning mechanism 3 is tightened, the No. 1 fastener 33 limits one end of the bald screw 31, and the No. 2 fastener 34 limits the other end of the bald screw 31 to ensure that the bald screw 31 will not fall off the anode end plate 1 and the cathode end plate 2.

[0025] In the above design, the structural design and specific implementation method of the tensioning mechanism 3 can effectively ensure the connection firmness between the entire tensioning mechanism 3, the anode end plate 1 and the cathode end plate 2.

[0026] Specifically: Figure 3 As shown, the No. 1 fastener 33 and the No. 2 fastener 34 have the same structure. The No. 1 fastener 33 includes a spring 331 and a nut 332 threadedly connected to the end of the bald screw 31. The two ends of the spring 331 are respectively against the nut 332 and the outer side of the anode end plate 1.

[0027] In actual use, the two ends of the spring 331 are respectively against the nut 332 and the rectangular frame 11, so that the rectangular frame 11 will not shake along the direction of the screw.

[0028] In the above design, the structural design and specific implementation of the No. 1 fastener 33 and the No. 2 fastener 34 facilitate the connection with the rectangular frame 11 .

[0029] Specifically: the anode end plate 1 includes a plurality of horizontal tubes and a plurality of vertical tubes.

[0030] In actual use, the horizontal tubes and the vertical tubes form a frame structure, and a stable structure is formed by the mutual support of the horizontal tubes and the vertical tubes. The horizontal tubes and the vertical tubes form a flow channel for electrolyte to pass through.

[0031] In the above design, the structural design and specific implementation of the anode end plate 1 can achieve normal flow of the electrolyte and structural stability of the entire rectangular frame 11 .
