Description

Technical Field

[0001] The utility model relates to the technical field of zinc electrowinning production by wet zinc smelting, in particular to a novel zinc electrowinning copper bar connecting device. Background Art

[0002] Zinc electrowinning in hydrometallurgy is to purify the zinc sulfate aqueous solution that has been cleaned of various harmful impurities, use a multi-element alloy plate with Pb-Ag as the main component as the anode, and a pure aluminum rolled plate as the cathode. Under the action of external potential direct current, the positively charged zinc ions in the solution discharge and deposit on the cathode, while the negatively charged OH ions in the solution discharge and precipitate oxygen on the anode. In the hydrometallurgy process, zinc electrowinning is the main energy-consuming process, among which the AC power consumption of zinc electrowinning accounts for more than 70% of the energy consumption of the entire process. Therefore, reducing the AC power consumption of zinc electrowinning has a positive significance for reducing the production cost of hydrometallurgy. In the zinc electrowinning process, the straight copper busbar is a conductive carrier that provides electrical energy to the zinc electrowinning cathode and anode plates. The conductive effect of the straight copper busbar directly affects the AC power consumption of zinc electrowinning.

[0003] Traditionally, the straight copper busbar is connected to the busbar by welding. That is, a 5mm deep groove is cut every 60mm on a 25mm thick copper plate, and then the straight copper busbar is welded in the groove of the copper plate. After welding, the whole copper plate is welded to the top of the busbar to complete the conductive connection. This connection method has the following disadvantages during actual use: 1. During the zinc sheet unloading process, the electrolyte of the cathode plate will drip onto the straight copper busbar, and the acid mist generated during the electrolytic deposition process will gradually corrode the welding point of the straight copper busbar over time, causing the straight copper busbar to loosen and fall off, affecting the conductivity of the copper busbar; 2. After the straight copper busbar is corroded and thinned, it cannot be replaced during normal production and must be stopped for processing; 3. The straight copper plate is welded to the busbar, and only 4 surfaces can be welded. The middle position cannot be welded. In the acid mist environment, verdigris will be generated in the middle of the busbar and the copper plate, thereby reducing the contact surface between the two, resulting in poor conductivity of the busbar, severe heat generation, and even the welding point will be stretched; 3. During the annual maintenance period, more than 6 mechanics must be arranged to work overtime to weld and reinforce the busbar. Each welding position needs to be heated to more than 600°C with oxygen and acetylene before welding, so the welding process is very cumbersome and hard, and the labor intensity of the mechanics is relatively high Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a novel zinc electrodeposition copper busbar connection device to solve the technical problems raised in the above background.

[0005] To achieve the above object, the present utility model provides the following technical solution: a novel zinc electrowinning copper row connection device, which includes a conductive busbar and a plurality of one-piece copper rows. The sides of the plurality of one-piece copper rows are all trapezoidal structures with a wider bottom and a narrower top. The conductive busbar is provided with a plurality of trapezoidal grooves with a wider bottom and a narrower top. The bottom width of the side of the one-piece copper row is equivalent to the bottom width of the trapezoidal groove. The plurality of one-piece copper rows are embedded on the conductive busbar through the trapezoidal grooves.

[0006] Further, the conductive busbar is in a cuboid structure, with a length of 4600 mm, a width of 210 mm, and a height of 250 mm.

[0007] Further, the spacing between the plurality of trapezoidal grooves is 60 mm, the bottom width of the trapezoidal groove is 16 mm, the top width is 12.3 mm, and the height is 50 mm.

[0008] Further, the length of the one-piece copper row is 210 mm, its side is a trapezoidal structure, the bottom width of the side is 16 mm, the top width is 6 mm, and the height is 135 mm.

[0009] By setting trapezoidal grooves on the conductive busbar in the present utility model, the bottom of the one-piece copper row is equivalent to the trapezoidal groove, and the one-piece copper row can be directly embedded into the trapezoidal groove. The one-piece copper row can be fixedly connected to the conductive busbar without welding. This not only facilitates replacement and reduces maintenance time, but also the overall conductivity of the busbar is good, the average temperature can be reduced by about 5 °C, the power loss of converting electrical energy into heat energy can be reduced, the alternating current consumption of zinc electrowinning can be reduced, and the zinc smelting cost can be reduced.
