Description

Technical Field

[0001] This utility model relates to the field of electrowinning smelting technology, and in particular to an electrowinning copper device. Background Technology

[0002] Electrolytic copper deposition is a crucial step in hydrometallurgy. It works by using electrolysis to deposit copper ions from a copper sulfate solution onto the cathode, thus obtaining high-purity metallic copper. However, existing electrolytic copper deposition equipment often suffers from problems such as uneven electrolyte distribution, significant concentration polarization, and inconvenient electrode replacement. These issues lead to low deposition efficiency and poor purity and surface quality of the produced copper, failing to meet the demands of high-quality production. Therefore, structural optimization of the electrolytic copper deposition equipment is necessary to address these problems. Utility Model Content

[0003] The purpose of this invention is to provide an electrolytic copper electrodeposition device to solve the problems of uneven electrolyte distribution, low electrolytic copper electrodeposition efficiency, and poor product quality in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An electrolytic copper electrolysis apparatus includes an electrolytic cell. A cover plate is detachably and fixedly connected to the top of the electrolytic cell. Six insulating seats are fixedly connected to the top of the cover plate. Conductive bars are fixedly sleeved within the insulating seats. An anode plate is detachably and fixedly connected to the bottom of the left conductive bar, and a cathode plate is detachably and fixedly connected to the bottom of the right conductive bar. A connecting seat is fixedly connected to the top of both the anode and cathode plates. A disassembly and replacement mechanism is provided between the connecting seat and the conductive bar. A uniform liquid inlet / outlet mechanism is provided between the cover plate and the electrolytic cell. Three partitions are fixedly connected to the bottom of the cover plate, located between the anode and cathode plates. A stirring mechanism is provided on the electrolytic cell.

[0006] As a preferred embodiment of this utility model, the disassembly and replacement mechanism includes four triangular blocks, a conductive base fixedly connected to the bottom of the conductive busbar, and an insert fixedly connected to the top of the connector. Two ear plates are fixedly connected to both sides of the conductive base, and the four triangular blocks are respectively fixedly connected to both sides of the connector. An elastic part is fixedly connected to the bottom of the ear plate, and a locking block is fixedly connected to the bottom of the elastic part. The locking block is movably engaged with the bottom of the triangular block.

[0007] In a preferred embodiment of this invention, the insert block is movably inserted into the conductive base, and the connecting base is movably abutted against the bottom of the conductive base.

[0008] As a preferred embodiment of this invention, one side of the ear plate is threaded with a screw, and the insert is fixedly connected to the conductive base by four screws.

[0009] As a preferred embodiment of this utility model, the top of the cover plate has six mounting holes, the insulating seat is movably inserted into the corresponding mounting holes, and the top of the insulating seat is threaded with two fixing screws, and the insulating seat is fixedly connected to the top of the cover plate by the two fixing screws.

[0010] As a preferred embodiment of this utility model, the uniform liquid inlet and outlet mechanism includes a liquid inlet component and a liquid outlet component. The liquid inlet component includes multiple liquid inlet pipes fixedly connected to the bottom of the electrolytic cell. The bottom ends of the multiple liquid inlet pipes are fixedly connected to the same main pipe. A flow meter is installed on each liquid inlet pipe. A rotary motor is fixedly connected to one side of each liquid inlet pipe. Rotary shafts are rotatably connected to both sides of each liquid inlet pipe. The output shaft of the rotary motor is fixedly connected to one end of the corresponding rotary shaft. A gate is fixedly connected between the two rotary shafts.

[0011] As a preferred embodiment of this invention, the liquid outlet assembly includes an annular tube fixedly connected to the top of the cover plate, and the bottom of the annular tube is fixedly connected to multiple liquid outlet pipes.

[0012] As a preferred embodiment of this utility model, sealed bearings are fixedly connected to both sides of the liquid inlet pipe, and the two rotating shafts are respectively fixedly sleeved in the inner ring of the corresponding sealed bearings.

[0013] As a preferred embodiment of the present invention, the stirring mechanism includes a stirring motor fixedly connected to one side of the electrolytic cell, a stirring shaft fixedly connected to the output shaft of the stirring motor, and a plurality of stirring rods fixedly connected to the outer side of the stirring shaft.

[0014] As a preferred embodiment of this invention, a drain pipe is fixedly connected to one side of the bottom of the electrolytic cell, and a control valve is provided on the drain pipe.

It also facilitates the removal and placement of the cathode plate and the stripping of copper products. The cathode plate is made of pure copper or stainless steel, which ensures the quality of copper deposition. The partition slows down the flow rate of the electrolyte, allowing copper ions sufficient time to deposit on the cathode plate, while avoiding interference between adjacent electrodes.

Through the arrangement of a main pipe and multiple inlet pipes in the liquid inlet assembly, and the combination of an adjustable-angle gate and a flow meter on each inlet pipe, the flow rate of the inlet pipe can be regulated, ensuring that the electrolyte enters the electrolytic cell evenly and avoiding excessively high or low local electrolyte concentrations. Simultaneously, the liquid inlet volume of each area can be controlled according to actual needs. The arrangement of multiple outlet pipes and annular pipes facilitates the discharge of gases and accumulated impurities generated during electrolysis, ensuring the purity of the electrolyte. The rotation of the stirring shaft and stirring rod driven by the stirring motor enhances electrolyte convection, further reducing concentration polarization and improving electrolysis efficiency. The drain pipe facilitates the periodic discharge of sediment and impurities from the bottom of the electrolytic cell, ensuring a clean electrolysis environment.

[0017] This utility model has a reasonable structural design. Through the design of multiple liquid inlet pipes at the bottom and uniform liquid outlet at the top, combined with the setting of adjustable angle gate, flow meter and stirring mechanism, it can effectively improve the uniformity of electrolyte, reduce concentration polarization, facilitate the uniform deposition of copper ions on the cathode, improve the quality of copper products, facilitate the disassembly and replacement of anode / cathode plates, and facilitate the removal and placement of cathode plates and the peeling of copper products.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 An electrolytic copper electrolysis device includes an electrolytic cell 1. A cover plate 2 is detachably and fixedly connected to the top of the electrolytic cell 1. Six insulating seats 4 are fixedly connected to the top of the cover plate 2. Conductive busbars 5 are fixedly sleeved inside the insulating seats 4. An anode plate 12 is detachably and fixedly connected to the bottom of the left conductive busbar 5, and a cathode plate 11 is detachably and fixedly connected to the bottom of the right conductive busbar 5. A connecting seat 98 is fixedly connected to the top of both the anode plate 12 and the cathode plate 11. A disassembly and replacement mechanism 9 is provided between the connecting seat 98 and the conductive busbar 5. A uniform liquid inlet and outlet mechanism 7 is provided between the cover plate 2 and the electrolytic cell 1. Three partitions 10 are fixedly connected to the bottom of the cover plate 2. The partitions 10 are located between the anode plate 12 and the cathode plate 11. A stirring mechanism 8 is provided on the electrolytic cell 1.

[0025] Furthermore, refer to Figures 1-3 The disassembly and replacement mechanism 9 includes four triangular blocks 96, a conductive base 91 fixedly connected to the bottom of the conductive busbar 5, and an insert 92 fixedly connected to the top of the connector 98. Two ear plates 93 are fixedly connected to both sides of the conductive base 91. The four triangular blocks 96 are fixedly connected to both sides of the connector 98. An elastic part 95 is fixedly connected to the bottom of the ear plate 93. A locking block 97 is fixedly connected to the bottom of the elastic part 95. The locking block 97 is movably locked into the bottom of the triangular block 96. The insert 92 is movably inserted into the conductive base 91. The connector 98 is movably abutted against the bottom of the conductive base 91. A screw 94 is threadedly connected to one side of the ear plate 93. The insert 92 is fixedly connected to the conductive base 91 by four screws 94.

[0026] The above scheme employs a four-part elastic mechanism 95, a triangular block 96, and a locking block 97 to secure the connecting seat 98 and the insert block 92 to the conductive seat 91. To ensure a secure installation, the screw 94 is tightened so that it screws into the threaded groove of the insert block 92, thereby locking the insert block 92 and the connecting seat 98. This significantly improves the secure installation of the anode plate 12 / cathode plate 11 and facilitates the disassembly and replacement of the anode plate 12 / cathode plate 11, making it easier to replace and maintain the anode plate. It also facilitates the removal and placement of the cathode plate 11 and the stripping of copper products. The cathode plate is made of pure copper or stainless steel, ensuring the quality of copper deposition. The partition 10 slows down the flow rate of the electrolyte, allowing sufficient time for copper ions to deposit on the cathode plate 11, while also preventing interference between adjacent electrodes.

[0027] Furthermore, the top of the cover plate 2 has six mounting holes, and the insulating seat 4 is movably inserted into the corresponding mounting holes. The top of the insulating seat 4 is threaded with two fixing screws 6. The insulating seat 4 is fixedly connected to the top of the cover plate 2 by the two fixing screws 6, which facilitates the disassembly and assembly of the insulating seat 4 and the conductive busbar 5.

[0028] Furthermore, refer to Figure 1 , Figure 2 and Figure 4 The uniform liquid inlet and outlet mechanism 7 includes an inlet component and an outlet component. The inlet component includes multiple inlet pipes 72 fixedly connected to the bottom of the electrolytic cell 1. The bottom ends of the multiple inlet pipes 72 are fixedly connected to the same main pipe 71. A flow meter 73 is installed on the inlet pipe 72. A rotary motor 76 is fixedly connected to one side of the inlet pipe 72. Rotary shafts 78 are rotatably connected to both sides of the inlet pipe 72. The output shaft of the rotary motor 76 is fixedly connected to one end of the corresponding rotary shaft 78. The same gate 77 is fixedly connected between the two rotary shafts 78. The outlet component includes an annular pipe 74 fixedly connected to the top of the cover plate 2. Multiple outlet pipes 75 are fixedly connected to the bottom of the annular pipe 74.

[0029] The above scheme employs a main pipe 71 and multiple inlet pipes 72 in the liquid inlet assembly. The inlet pipes 72 are equipped with adjustable-angle gates 77 and flow meters 73, allowing for flow rate regulation. This ensures the electrolyte enters the electrolytic cell 1 uniformly, preventing localized excessively high or low electrolyte concentrations. Simultaneously, the inlet volume of each area can be controlled according to actual needs. The multiple outlet pipes 75 and the annular pipe 74 facilitate the removal of gases and accumulated impurities generated during electrolysis, ensuring the purity of the electrolyte.

[0030] Furthermore, sealed bearings are fixedly connected to both sides of the inlet pipe 72, and two rotating shafts 78 are respectively fixedly sleeved in the inner ring of the corresponding sealed bearings, which can support the rotating shafts 78 and make their rotation more stable.

[0031] Furthermore, refer to Figure 2 The stirring mechanism 8 includes a stirring motor 81 fixedly connected to one side of the electrolytic cell 1, a stirring shaft 82 fixedly connected to the output shaft of the stirring motor 81, and a plurality of stirring rods 83 fixedly connected to the outside of the stirring shaft 82.

[0032] The above solution involves using a stirring motor 81 to drive the rotation of the stirring shaft 82 and the stirring rod 83, which enhances the convection of the electrolyte, further reduces concentration polarization, and improves electrolysis efficiency.

[0033] Furthermore, a drain pipe 3 is fixedly connected to the bottom of one side of the electrolytic cell 1. A control valve is installed on the drain pipe 3. Through the drain pipe 3, it is convenient to periodically discharge the sludge and impurities at the bottom of the electrolytic cell to ensure the cleanliness of the electrolysis environment.

[0034] In this invention, during use, the connecting seat 98 and the insert 92 can be fixed on the conductive seat 91 by the elastic engagement of four sets of elastic parts 95, triangular blocks 96 and locking blocks 97. To ensure the firmness of the installation, the screws 94 are tightened so that they are screwed into the threaded grooves opened in the insert 92, thereby locking the insert 92 and the connecting seat 98. This greatly improves the firmness of the anode plate 12 / cathode plate 11 installation and facilitates the disassembly and replacement of the anode plate 12 / cathode plate 11, making it convenient for the replacement and maintenance of the anode plate; it also facilitates the removal and placement of the cathode plate 11 and the peeling of copper products; the cathode plate is a pure copper plate or a stainless steel plate, which can ensure the quality of copper deposition. The partition 10 can slow down the flow rate of the electrolyte, allowing copper ions sufficient time to deposit on the cathode plate 11, while avoiding interference between adjacent electrodes.

[0035] The main pipe 71 and multiple inlet pipes 72 in the liquid inlet assembly, with an adjustable gate 77 and flow meter 73 on each inlet pipe 72, allow for flow control of the liquid inlet pipe 72. This ensures that the electrolyte enters the electrolytic cell 1 evenly, preventing local electrolyte concentrations from being too high or too low. Simultaneously, the liquid inlet volume in each area can be controlled according to actual needs. The multiple outlet pipes 75 and the annular pipe 74 facilitate the removal of gases and accumulated impurities generated during electrolysis, ensuring the purity of the electrolyte. The stirring motor 81 drives the rotation of the stirring shaft 82 and stirring rod 83, enhancing electrolyte convection, further reducing concentration polarization, and improving electrolysis efficiency. The drain pipe 3 facilitates the periodic removal of sediment and impurities from the bottom of the electrolytic cell, ensuring a clean electrolysis environment.
