Abstract

This utility model discloses an electrochemical device and equipment. The electrochemical device includes an electrolysis assembly and a support frame. The electrolysis assembly includes a conductive bus, a connector, and an electrode plate. The conductive bus is mounted on top of the electrolysis cell. The first end of the connector is connected to the conductive bus, and the second end of the connector is connected to the electrode plate. The support frame includes a frame body and flow-deflecting ribs. The frame body is disposed inside the electrolysis cell and is used to allow the electrode plate to extend into it. The flow-deflecting ribs extend along a first transverse direction on the frame body and are used to shield the second end of the connector in a second transverse direction. The second end of the connector is connected to the electrode plate. The flow-deflecting ribs obstruct the second end of the connector, causing the flow state of the electrolyte flowing through the flow-deflecting ribs to change under the obstruction of the flow-deflecting ribs. This effectively prevents particles in the electrolyte from accumulating at the second end of the connector, thereby preventing nodule formation and granulation on the electrode plate surface and improving the surface quality of the cathode plate.

[0028] Detailed Implementation

[0029] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0030] The electrochemical device of this invention is described below with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown, this utility model provides an electrochemical device, which includes an electrolysis assembly 100 and a support frame. The electrolysis assembly 100 includes a conductive bus 110, a connector 120, and an electrode 130. The conductive bus 110 is mounted on the top of the electrolysis cell. The first end 121 of the connector 120 is connected to the conductive bus 110, and the second end 122 of the connector 120 is connected to the electrode 130. The support frame includes a frame body 200 and a baffle 300. The frame body 200 is disposed in the electrolysis cell and is used to allow the electrode 130 to extend into it. The baffle 300 extends along a first transverse direction on the frame body 200 and is used to block the second end 122 of the connector 120 in a second transverse direction.

[0032] The electrochemical device of this invention can be used in electrochemical equipment for metal electrodeposition. The electrode plate 130 is a cathode plate, and the connector 120 can be a lug, hook, buckle, or other connector used to connect the conductive busbar 110 and the electrode plate 130. The conductive busbar 110 is a group of metallic conductors, generally rod-shaped, used to support and fix other objects, and to bear and transmit loads. In some embodiments, the conductive busbar 110 is also called a busbar or conductive beam, etc. When the metallic conductor is a copper conductor, it is also called a copper busbar.

[0033] It should be noted that, taking the connection of connector 120 to the cathode plate by means of lifting lug riveting as an example, during the metal electrodeposition process, the riveting structure of the cathode plate and the lifting lug is immersed in the electrolyte for a long time. Due to the low processing precision, burr residue and uneven surface of the riveting structure, metal ions in the electrolyte are very likely to accumulate at the riveting structure, resulting in nodules and granules on the surface of the cathode plate.

[0034] Specifically, the frame body 200 is disposed inside the electrolytic cell, the conductive bus 110 is mounted on the top of the electrolytic cell, the electrode plate 130 is connected to the conductive bus 110 via the connector 120 and extends into the frame body 200, and the turbulence-deflecting ribs 300 on the frame body 200 extend along a first transverse direction and block the second end 122 of the connector 120 in a second transverse direction; wherein, the first transverse direction is configured as follows: Figure 2 The left and right directions are shown, and the second horizontal direction is set as follows: Figure 2 In the front-back direction shown, the second end 122 of the connector 120 is connected to the electrode plate 130. The turbulence rib 300 blocks the second end 122 of the connector 120, that is, the projection area of ​​the turbulence rib 300 in the second transverse direction covers the second end 122 of the connector 120. The turbulence rib 300 can be set at a distance from the second end 122 of the connector 120 or abut against the second end 122 of the connector 120, so that the electrolyte flowing through the turbulence rib 300 changes the flow state of the electrolyte under the blocking effect of the turbulence rib 300, and can increase the Reynolds number (Re) of the electrolyte, so that the electrolyte generates eddies. In some cases, it can change from a laminar flow state to a turbulent flow state, effectively preventing the accumulation of particles in the electrolyte at the second end 122 of the connector 120, thereby preventing nodules and particles from forming on the surface of the electrode plate 130 and improving the surface quality of the cathode sheet.

[0035] In some embodiments, the turbulence rib 300 blocks the connection between the second end 122 and the electrode plate 130 in the second lateral direction. That is, the connection between the second end 122 and the electrode plate 130 is blocked by the turbulence rib 300 in the second lateral direction, which is beneficial to further improve the effect of the turbulence rib 300 in changing the electrolyte flow state to prevent nodules and particles from forming on the surface of the electrode plate 130, and further improve the surface quality of the cathode sheet.

[0036] Furthermore, the number of deflector ribs 300 is set to two, the two deflector ribs 300 are arranged at a second transverse interval, and there is a mounting opening 310 between the two deflector ribs 300 for the electrode plate 130 to pass through. Figures 3 to 5 As shown, two turbulence ribs 300 are provided on the frame body 200 and are spaced apart in the front-back direction. An installation port 310 is formed between the two turbulence ribs 300, so that the electrode plate 130 can pass through the installation port 310 and extend into the frame body 200. Both turbulence ribs 300 can agitate the electrolyte, which increases the electrolyte flow rate on both sides of the electrode plate 130 and can change into a chaotic and irregular flow state. This simultaneously prevents nodules and granules from forming on both sides of the electrode plate 130, and further improves the surface quality of the electrode.

[0037] In this embodiment of the utility model, the frame body 200 includes a bottom frame 210 and two side frames 220. The two side frames 220 are arranged at two ends of the bottom frame 210 along a first lateral distance. The two ends of the turbulence ribs 300 are respectively connected to the two side frames 220 one by one. A mounting cavity 230 is formed between the bottom frame 210 and the two side frames 220. The mounting cavity 230 is connected to the mounting opening 310 and is used for the electrode plate 130 to extend into.

[0038] like Figures 1 to 4 As shown, two side frames 220 are respectively connected to the left and right ends of the bottom frame 210 to form a mounting cavity 230. Two turbulence ribs 300 are arranged at intervals along the second lateral direction above the bottom frame 210, and the mounting opening 310 between the two turbulence ribs 300 is connected to the mounting cavity 230, so that the electrode plate 130 can pass through the mounting opening 310 and extend into the mounting cavity 230. Thus, the two turbulence ribs 300 are respectively arranged on both sides of the electrode plate 130 and correspondingly block the second end 122 of the connector 120. The electrode plate 130 is easy to install and effectively prevents nodules and granules from forming on the surface of the electrode plate 130.

[0039] Furthermore, the frame body 200 also includes two support grid plates 240, which are spaced apart along a second lateral direction on the bottom frame 210, and the mounting cavity 230 is located between the two support grid plates 240. Figures 1 to 5 As shown, both support grids 240 are connected to the upper side of the bottom frame 210, and a mounting cavity 230 for accommodating the electrode plate 130 is formed between the two support grids 240. The support grids 240 serve to support the electrode plate 130, thereby improving the bending stiffness and structural strength of the frame body 200. Furthermore, the grid-shaped perforated arrangement of the support grids 240 can reduce the flow resistance of the electrolyte, accelerate the flow rate of the electrolyte, and improve the electrolytic electrowinning efficiency.

[0040] In the embodiments of this utility model, such as Figures 2 to 5As shown, a plurality of first drain holes 221 are provided on the side frame 220 at intervals, and a plurality of second drain holes 211 are provided on the bottom frame 210 at intervals. Both the first drain holes 221 and the second drain holes 211 are used to allow the electrolyte to pass through, thereby increasing the flow rate of the electrolyte and further improving the electrolytic electrowinning efficiency.

[0041] In this embodiment of the invention, the side frame 220 includes a connecting section 222 and an extension section 223. The lower end of the connecting section 222 is connected to the bottom frame 210, and the lower end of the extension section 223 is connected to the upper end of the connecting section 222 and to the baffle rib 300. The upper end of the extension section 223 is used to extend beyond the surface of the electrolyte. Figures 2 to 5 As shown, the turbulence rib 300 is connected to the lower end of the extension section 223 so that the turbulence rib 300 can be immersed in the electrolyte to agitate the electrolyte and prevent metal ions and other particles in the electrolyte from accumulating at the second end 122 of the connector 120, thereby preventing nodules and particles from forming on the surface of the electrode plate 130. The upper end of the extension section 223 can extend above the surface of the electrolyte to facilitate positioning and placement of the frame body 200, thus improving the ease of assembly and disassembly.

[0042] Furthermore, such as Figures 3 to 5 As shown, the extension section 223 is provided with a guide groove 225, which guides the electrode plate 130 to extend into the mounting cavity 230, improving the ease of installation of the electrode plate 130. In addition, the upper end of the extension section 223 is formed with an inclined wall 226, which facilitates demolding during the manufacturing process of the frame body 200, simplifying the manufacturing process.

[0043] In this embodiment of the present invention, the extension section 223 includes a transition section 223a and an extension section 223b. The lower end of the transition section 223a is connected to the upper end of the connecting section 222 and is connected to the baffle rib 300. The extension section 223b is connected to the upper end of the transition section 223a and is used to extend out of the electrolyte surface. A through hole 224 is provided on the extension section 223b.

[0044] like Figures 2 to 5 As shown, the adapter 223a is connected between the connecting section 222 and the extension 223b, so that the turbulence rib 300 connected to the adapter 223a can be immersed in the electrolyte to change the flow state of the electrolyte, thereby preventing nodules and granules. The extension 223b is used to extend to the surface of the electrolyte and has a through hole 224. The frame body 200 is hoisted through the through hole 224 to realize the picking and putting of the frame body 200, which further improves the convenience of disassembly and assembly.

[0045] In this embodiment of the invention, an anti-crystallization notch 320 is formed between the frame body 200 and the baffle ribs 300, and the anti-crystallization notch 320 is located on the side of the baffle ribs 300 facing the conductive busbar 110. It should be noted that the temperature of the electrolyte is usually above 60°C. The high temperature of the electrolyte will produce water vapor that evaporates above the electrolyte surface. When the water vapor adheres to the rods and ribs, it will crystallize, resulting in ion depletion on the surface of the electrode plate 130, and thus producing quality defects such as black spots on the surface of the electrode plate 130.

[0046] like Figures 1 to 5 As shown, the ribs 300 extend in the left and right direction, and the two ends of the ribs 300 are respectively connected to the two side frames 220. An anti-crystallization notch 320 is formed between the ribs 300 and the two side frames 220, and the anti-crystallization notch 320 is located on the upper side of the ribs 300. The support grid plate 240 is connected to the lower side of the ribs 300. The ribs 300 are used to be immersed in the electrolyte. The anti-crystallization notch 320 avoids water vapor from adhering and forming crystals, thereby preventing ion depletion on the surface of the electrode plate 130 and the generation of black spots, and further improving the surface quality of the electrode.

[0047] In this embodiment of the invention, the baffle rib 300 is integrally formed on the frame body 200. Both the frame body 200 and the baffle rib 300 are made of fiberglass resin, epoxy resin, vinyl ester resin, or polypropylene. Specifically, both the frame body 200 and the baffle rib 300 can be made of fiberglass resin, epoxy resin, vinyl ester resin, or polypropylene, which gives the support frame the advantages of strong resistance to deformation, high structural strength, and high corrosion resistance, thus extending the service life of the support frame.
