Description

Technical Field

[0001] This utility model patent belongs to the field of hydrometallurgical electrowinning technology, specifically relating to a combined conductive device for the surface of an electrolytic cell in the electrowinning industry. Background Technology

[0002] Currently, the sulfuric acid-based cobalt-nickel electrowinning processes used in hydrometallurgy and environmental protection both domestically and internationally employ a cathode-bag diaphragm electrowinning process. This process divides the anode and cathode into several small sections with a fixed inter-electrode distance. Under the influence of current, electrons are deposited in the cathode region, resulting in a reduction reaction that produces electrowinning nickel, while electrons are received in the anode region, resulting in an oxidation reaction that produces a large amount of oxygen. To ensure the smooth introduction of metal ions from the solution onto the cathode plate, conductive copper rods are used above the anode and cathode regions to guide the ions onto the cathode and anode. The conductive ions are then transferred under the influence of current. Therefore, a conductive device needs to be designed. Furthermore, existing electrowinning processes often suffer from the following problems: 1. Inaccurate positioning between the cathode and anode rods can lead to short circuits; 2. Poor contact between the anode and cathode rods and the conductive copper busbars can cause overheating; 3. Liquids and debris used during tank cleaning can easily flow into the electrowinning tank, causing contamination. Therefore, it is urgent to develop a combined conductive device for the electrolytic cell surface suitable for this type of electrowinning and to solve the problems existing in the current process. Utility Model Content

[0003] To address the aforementioned issues, the purpose of this utility model patent is to provide a combined conductive device for the electrolytic cell surface in the electrowinning industry, thereby solving the problems existing in the current process.

[0004] To achieve the above objectives, the specific technical solution is as follows:

[0005] An electrolytic cell surface combined conductive device includes a liquid receiving box, a rubber insulating pad, a conductive copper busbar, and a resin insulating partition.

The rubber insulating pad is embedded in the liquid receiving box, the conductive copper busbar is placed on the rubber insulating pad, and the resin insulating partition is placed on the conductive copper busbar. The liquid receiving box has two concave and convex sidewalls for positioning the cathode rod and anode rod and for preventing liquid and impurities from overflowing. The bottom inner side of the liquid receiving box has two grooves to facilitate the discharge of liquid and impurities from the liquid receiving box.

[0006] Furthermore, the side wall of the liquid receiving box is provided with an inverted trapezoidal groove and an arc-shaped groove for receiving the corresponding cathode rod and anode rod; the inverted trapezoidal groove and the arc-shaped groove are arranged alternately in sequence.

[0007] Furthermore, the upper surface of the conductive copper busbar is provided with through arc-shaped protrusions on both sides.

[0008] Furthermore, the resin insulating partition is disposed on the conductive copper busbar, and openings are provided at intervals on the resin insulating partition corresponding to the arc-shaped protrusions of the conductive copper busbar.

[0009] Furthermore, gaps are reserved between the two side edges of the rubber insulating pad, the conductive copper busbar and the resin insulating partition and the corresponding side wall of the liquid receiving box, and the bottom of the gaps connects to the groove at the bottom of the liquid receiving box.

[0010] The beneficial effects of this utility model patent are as follows:

[0018] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0019] like Figures 1 to 3As shown, a combined conductive device for the surface of an electrolytic cell in the electrowinning industry includes a liquid receiving box 1, a rubber insulating pad 2, a conductive copper busbar 3, and a resin insulating partition 4. The liquid receiving box 1 is installed on the surface of the electrolytic cell 5, the rubber insulating pad 2 is embedded in the liquid receiving box 1, the conductive copper busbar 3 is disposed on the rubber insulating pad 2, and the resin insulating partition 4 is a thin insulating layer disposed on the conductive copper busbar 3.

[0020] The liquid receiving box 1 has two side walls 7 with concave and convex designs. The side walls 7 are provided with an inverted trapezoidal groove 71 and an arc-shaped groove 72, which match the end shapes of the cathode rod 8 and anode rod 9. These grooves are used to receive the corresponding cathode rod 8 and anode rod 9, enabling their positioning and preventing liquid and debris from overflowing. The bottom inner side of the liquid receiving box 1 has two grooves 6 to facilitate the drainage of liquid and debris from within the box. The inverted trapezoidal groove 71 and the arc-shaped groove 72 are alternately arranged to sequentially and alternately position the cathode rod 8 and anode rod 9.

[0021] Preferably, the upper surface of the conductive copper busbar 3 is provided with through arc-shaped protrusions 10 on both sides to prevent liquid and crystal deposition on the contact surface between the anode and cathode rods and the conductive copper busbar, which can enhance the conductivity between the cathode rod 8 and the anode rod 9, effectively reduce the number of daily maintenance times, and make later use, maintenance and cleaning more convenient.

[0022] The resin insulating partition 4 is disposed on the conductive copper busbar 3. Openings 41 are spaced apart on the resin insulating partition 4 corresponding to the arc-shaped protrusions 10 of the conductive copper busbar 3, exposing the arc-shaped protrusions 10 of the conductive copper busbar 3, for isolating the cathode rod 8 and the anode rod 9. Both the cathode rod 8 and the anode rod 9 have conductive rods at both ends. During positioning, for example, if the anode rod 9 is placed on the conductive copper busbar 3, then the cathode rod 8 must be placed on the resin insulating partition 4, alternating between the two to achieve isolation.

[0023] This utility model's liquid receiving box 1 is made of fiberglass material, possessing excellent insulation and corrosion resistance. It features two concave-convex sidewalls 7 for positioning the anode and cathode rods and preventing liquid and debris spillage. The bottom inner side of the receiving box 1 has two grooves 6 to facilitate the drainage of liquid and debris. Gaps 11 are provided between the two sides of the rubber insulating pad 2, the conductive copper busbar 3, and the resin insulating partition 4 and the corresponding sidewalls 7 of the receiving box 1. The bottom of these gaps 11 connects to the grooves 6 at the bottom of the receiving box 1, allowing cleaning fluid and debris to enter the grooves 6 and then drain out.

[0024] The rubber insulating pad 2 of the conductive device of this utility model has a certain elasticity, which can prevent the conductive copper busbar 3 set on it from shifting, and also has a certain insulation effect.

[0025] Similarly, the resin insulating partition 4 is made of fiberglass mixed resin material, which has a certain degree of insulation and corrosion resistance. It can effectively achieve electrical isolation between the cathode rod 8 and the anode rod 9, and can withstand a certain high temperature to prevent the anode and cathode rods from overheating and burning out.

[0026] like Figure 4 and Figure 5 As shown, the electrolytic cell surface combined conductive device of this utility model is installed between adjacent electrolytic cells 5 during application. The cathode rod 8 and anode rod 9 are installed on the conductive device and alternately contact the conductive copper busbar 3. The length of the conductive device matches the electrolytic cell 5. The above-mentioned surface combined conductive device can solve the short circuit problem caused by inaccurate positioning of the cathode and anode rods, and the heat generation problem caused by poor contact between the cathode and anode rods and the conductive copper busbar 3. It enhances the conductivity, reduces power consumption, and can prevent liquids and impurities used during cleaning of the cell surface from flowing into the electrowinning cell, thus improving product quality. It also has the characteristics of simple structure, low cost, and convenient maintenance, making it suitable for widespread application.

[0027] It should be noted that the internal structure of electrolytic cell 5 is existing technology and will not be described in detail here.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto.
