Description

Technical Field

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

[0002] Currently, the sulfuric acid system 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. These conductive ions are then transferred under the influence of current. Therefore, a conductive device needs to be designed. In addition, the existing electrowinning process often has the following problems: 1. Inaccurate positioning between the cathode rod and the anode rod 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 cleaning of the cell surface can easily flow into the electrowinning cell, causing contamination; 4. Different electrolytic cell sizes for different projects require the creation of new molds for the liquid receiving box and insulating plate, increasing project costs. 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] A segmented molded composite conductive device for an electrolytic cell surface includes a receiving box, a rubber insulating pad, a conductive copper busbar, and a resin insulating partition. The receiving box is installed on the surface of the electrolytic cell, located at the bottom of the composite conductive device. The rubber insulating pad is embedded in the receiving box, and the conductive copper busbar is placed on top of the rubber insulating pad. The resin insulating partition, which has a specific cut shape, is placed on top of the conductive copper busbar, and the upper surface of the conductive copper busbar is flat. The specific cut shape is as follows: a hollow strip is provided in the middle of the resin insulating partition, and alternating rectangular teeth are provided on both sides. After the cutting process, the conductive copper busbar is exposed underneath the resin insulating partition.

[0006] Furthermore, both the liquid receiving box and the resin insulating partition are segmented designs. The liquid receiving box is assembled from several liquid receiving box units, and the resin insulating partition is assembled from several resin insulating partition units. The liquid receiving box and the resin insulating partition are molded into segments and connected into a whole. This allows different projects to share molds, reducing project investment and standardizing spare parts dimensions.

[0007] Furthermore, the receiving box has two concave-convex sidewalls for positioning the cathode and anode rods and preventing liquid and debris from spilling out.

[0008] Furthermore, the rectangular teeth on both sides of the resin insulating partition are staggered.

[0009] 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.

[0010] Furthermore, the bottom inner side of the liquid receiving box has two grooves to facilitate the discharge of liquid debris from the liquid receiving box.

[0011] 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.

[0012] The beneficial effects of this utility model patent are as follows:

[0013] The segmented molding and assembly conductive device described above can solve the short circuit problem caused by inaccurate positioning of the anode and cathode rods, and the overheating problem caused by poor contact between the anode and cathode rods and the conductive copper busbars. It enhances conductivity, reduces power consumption, and prevents liquids and impurities used during cleaning from flowing into the electrolytic cell, thus improving product quality. The segmented assembly design of the receiving box and resin insulating partition makes it highly versatile, reduces mold costs, and effectively solves the problem of needing to re-make molds due to inconsistent electrolytic cell sizes in different projects, as well as the problem of inconsistent spare parts. It reduces project investment costs and features a simple structure, low cost, and convenient maintenance. The receiving box and resin insulating partition are molded, resulting in stronger product toughness and a simple structure, making them suitable for widespread application.

[0020] 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. Example 1

[0021] like Figures 1 to 5 As shown, a segmented molded composite 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.

[0022] The receiving box 1 has two side walls 7 with concave and convex designs. The side walls 7 are provided with inverted trapezoidal grooves 71 and arc-shaped grooves 72, which match the end shapes of the cathode rods 8 and anode rods 9. These grooves are used to receive the corresponding cathode rods 8 and anode rods 9, facilitating their positioning and preventing liquid and impurities from overflowing. The bottom inner side of the receiving box 1 has two grooves 6 to facilitate the drainage of liquid and impurities from within the receiving box 1. The inverted trapezoidal grooves 71 and arc-shaped grooves 72 are alternately arranged to alternately position the cathode rods 8 and anode rods 9. Both the receiving box 1 and the resin insulating partition 4 are assembled in separate units. The receiving box is segmented; in this embodiment, the segment size is preferably 700mm, and it is composed of multiple segments according to the size of the electrolytic cell. The resin insulating partition is also segmented; in this embodiment, the segment size is preferably 560mm, and it is composed of multiple segments according to the size of the electrolytic cell. The molding process involves segmented processing and assembly into a whole, allowing different projects to share the same mold, reducing project investment, and standardizing spare parts dimensions.

[0023] Preferably, the upper surface of the conductive copper busbar 3 is a flat surface, which does not require special processing services and reduces project investment costs.

[0024] The resin insulating partition 4 is disposed on the conductive copper busbar 3. The resin insulating partition 4 is an insulating partition with a specific cutting shape, and the upper surface of the resin insulating partition 4 is a flat surface. The specific cutting shape is as follows: a hollow strip is provided in the middle of the resin insulating partition 4, and alternating rectangular teeth are provided on both sides at intervals. After cutting, the resin insulating partition 4 exposes the conductive copper busbar 3 underneath (e.g., Figure 3 As shown), the cut and processed resin insulating partition exposes the copper surface of the conductive copper busbar 3, used to isolate 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, when the anode rod 9 is placed on the conductive copper busbar 3 (…), Figure 3 (Position A), then cathode rod 8 should be placed on the resin insulating partition ( Figure 3 Alternately set positions (B in the middle) to achieve isolation.

[0025] This utility model's liquid receiving box 1 is made of resin 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 10 are provided between the two side edges of the rubber insulating pad 2, conductive copper busbar 3, and resin insulating partition 4 and the corresponding sidewalls 7 of the receiving box 1. The bottom of these gaps 10 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.

[0026] 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.

[0027] Similarly, the resin insulating partition 4 is made of resin fiberglass mixed resin material, which has certain insulation and corrosion resistance, can effectively realize electrical isolation between the cathode rod 8 and the anode rod 9, and can withstand certain high temperatures to prevent the anode and cathode rods from overheating and burning out.

[0028] like Figure 4 and Figure 5As 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 is matched with the electrolytic cell 5 after segmented molding and assembly. The above-mentioned segmented molding 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 electrolytic cell. It effectively solves the problem of needing to re-make molds due to inconsistent sizes of electrolytic cells in different projects, as well as the problem of inconsistent spare parts, reducing project investment costs. It also features a simple structure, low cost, and convenient maintenance, making it suitable for widespread application.

[0029] It should be noted that the internal structure of electrolytic cell 5 is existing technology and will not be described in detail here.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
