[0031] In related technologies, the uncontrollability and instability of manual operation lead to the inability to uniformly and continuously add the additive solution to the electrolytic cell, which in turn causes fluctuations in the quality of electrolytic copper.

[0032] The following is for reference. Figures 1-3 A copper electrolysis additive addition system 1 according to an embodiment of the present invention is described.

[0033] like Figures 1-3As shown, the copper electrolytic additive addition system 1 according to the present invention includes an electrolytic cell, an additive dissolving device 11, and a first transmission pipeline 12. The electrolytic cell is used for the electrolytic refining of copper. In the electrolytic cell, by applying voltage, copper ions are reduced to metallic copper at the cathode, while oxidation may occur at the anode, generating other compounds or ions. The additive dissolving device 11 is used to dissolve and prepare the additive solution to be added to the electrolytic cell. The additive is used to adjust the composition and properties of the electrolyte to optimize the electrolysis process, improve the purity of copper, or improve the physical properties of electrolytic copper. An additive dissolving tank 111 is formed within the additive dissolving device 11, which is used to hold and dissolve the additive. One end of the first transmission pipeline 12 is connected to the electrolytic cell, and the other end of the first transmission pipeline 12 is connected to the outlet of the additive dissolving device 11, for conveying the dissolved additive solution from the outlet of the additive dissolving device 11 to the electrolytic cell.

[0034] The copper electrolysis additive addition system 1 also includes a first metering pump 13, which is a pump used for precise control of fluid flow rate. The first metering pump 13 is located in the first transmission line 12, thus allowing adjustment of the flow rate of the additive solution delivered from the additive dissolving device 11 to the electrolytic cell as needed. By precisely controlling the flow rate, it can be ensured that the additive solution is added to the electrolytic cell at a set rate, thereby maintaining the stability of the electrolysis process and obtaining high-quality electrolytic copper.

[0035] The copper electrolytic additive addition system 1 also includes an electronic control device 14, which is used to monitor and control various devices and processes in the copper electrolytic additive addition system 1. The electronic control device 14 is communicatively connected to the first metering pump 13, so the electronic control device 14 can receive information from the first metering pump 13 or other sensors, and send control commands to the first metering pump 13 to adjust its flow output based on the acquired information and preset control logic.

[0036] Through the communication connection between the electronic control device 14 and the first metering pump 13, data transmission and command exchange can be achieved between the electronic control device 14 and the first metering pump 13. The electronic control device 14 can adjust the operating status of the first metering pump 13 in real time according to the actual needs of the electrolytic copper production process, thereby precisely controlling the flow rate of the additive solution. This improves the automation level of the system, reduces manual operation, and ensures that the additive solution is added to the electrolytic cell uniformly and continuously, helping to maintain the stability and controllability of the electrolysis process, thus improving the quality and production efficiency of electrolytic copper.

[0037] Therefore, the copper electrolysis additive addition system 1 according to the present invention achieves precise control and uniform and continuous addition of the additive solution, thereby improving the stability of the electrolysis process and the quality and production efficiency of electrolytic copper.

[0038] According to some embodiments of the present invention, such as Figures 1-3 As shown, the copper electrolysis additive addition system 1 also includes a stirring device 15, which is used to ensure that the additive is fully and uniformly dissolved in the additive dissolving tank 111. The stirring device 15 is disposed on the additive dissolving device 11 to facilitate direct stirring of the solution in the additive dissolving tank 111. The stirring device 15 has a stirrer disposed in the additive dissolving tank 111, which stirs the solution by rotation or vibration.

[0039] The stirring device 15 is communicatively connected to the electronic control device 14, enabling the electronic control device 14 to control the operating state of the stirring device 15. Through this communication connection, the electronic control device 14 can receive information from the stirring device 15 or other sensors, and send control commands to the stirring device 15 based on the acquired information and preset control logic. Specifically, the electronic control device 14 can adjust the operating state of the stirring device 15 in real time, such as starting, stopping, or changing the stirring speed, to ensure that the additives can dissolve fully and uniformly in the dissolving tank. This helps improve the dissolution efficiency and concentration uniformity of the additive solution, thereby further optimizing the electrolysis process and improving the quality and production efficiency of electrolytic copper.

[0040] According to some embodiments of the present invention, such as Figure 1 As shown, the copper electrolysis additive addition system 1 also includes a heat source, a second transmission pipeline 16, and a medium valve 17. The heat source provides heat energy to heat a medium (such as steam) to transfer the heat energy to the additive dissolving device 11, helping the additive dissolve more quickly. The second transmission pipeline 16 is used to transmit the heating medium. One end of the second transmission pipeline 16 is connected to the heat source, and the other end is connected to the heating medium inlet of the additive dissolving device 11, allowing the heated medium to flow into the additive dissolving device 11 through the second transmission pipeline 16, providing it with the required heat. The medium valve 17 is located in the second transmission pipeline 16 and is used to regulate or cut off the flow of the heating medium.

[0041] Through the communication connection between the medium valve 17 and the electronic control device 14, the opening, closing or adjustment degree of the medium valve 17 can be executed according to the instructions of the electronic control device 14. The electronic control device 14 can send control instructions to the medium valve 17 through the communication connection according to the temperature requirements of the additive dissolving device 11 and the preset control strategy, thereby adjusting the opening degree or opening and closing state of the medium valve 17, so as to accurately control the flow rate and temperature of the heating medium and ensure that the temperature in the additive dissolving device 11 reaches the optimal state.

[0042] According to some embodiments of the present invention, such as Figure 1 and Figure 2As shown, the copper electrolysis additive addition system 1 also includes a water source, a third transmission pipeline 18, and an inlet valve 19. The water source provides the necessary water for the additive dissolving device 11. The third transmission pipeline 18 is used to transport water. One end of the third transmission pipeline 18 is connected to the water source, and the other end is connected to the inlet of the additive dissolving device 11, for transporting water from the water source to the additive dissolving device 11, so that the water from the water source can smoothly enter the additive dissolving device 11 through the third transmission pipeline 18. The water valve is installed in the third transmission pipeline 18, and the opening and closing state of the water valve can control the flow of water in the third transmission pipeline 18. When the water valve is in the open state, the water from the water source can flow smoothly along the third transmission pipeline 18 until it reaches the inlet of the additive dissolving device 11, providing the necessary water for the dissolving process. When the water source has provided enough water to the additive dissolving device 11, the water valve is closed to cut off the water flow, so that the liquid level in the additive dissolving tank 111 is at a preset height.

[0043] Through the communication connection between the water valve and the electronic control device 14, the opening and closing status of the water valve can be executed according to the instructions of the electronic control device 14. The electronic control device 14 can send control commands to the water valve through the communication connection according to the liquid level of the additive dissolution tank 111 and the preset control strategy, thereby adjusting the opening and closing status of the water valve. Whether it is necessary to add water or to cut off the water flow to prevent overflow, the electronic control device 14 can react quickly and accurately, which not only greatly reduces the burden on operators and improves work efficiency, but also makes the operation of the entire copper electrolysis additive addition system 1 more stable and reliable.

[0044] According to some embodiments of the present invention, the electronic control device 14 is configured to adjust the operating status of the stirring device 15, the water inlet valve 19 and the heating medium valve 17 according to the dissolution process of the additive in the additive dissolution tank 111.

[0045] During the dissolution process, the electronic control device 14 can automatically turn the stirring device 15 on or off according to the preset stirring speed and the actual situation in the dissolution tank, and adjust its speed to ensure that the additive can be fully dissolved and reach the expected concentration.

[0046] At different stages of the dissolution process, the electronic control device 14 will automatically open or close the water inlet valve 19 as needed to replenish or stop water replenishment. For example, during the primary and secondary water replenishment stages, the electronic control device 14 will control the opening and closing of the water inlet valve 19 respectively to ensure that the liquid level in the dissolution tank is maintained at a preset height.

[0047] During the dissolution process, the electronic control device 14 will automatically open or close the heating medium valve 17 and adjust its opening degree according to the preset temperature target and the actual temperature in the additive dissolution tank 111, so as to achieve precise control of the temperature in the additive dissolution tank 111. This not only helps to accelerate the dissolution process of the additive, but also ensures that the temperature in the additive dissolution tank 111 is always kept within a suitable range.

[0048] The electronic control device 14 achieves precise control of the additive dissolution process by intelligently regulating the operating status of the stirring device 15, the water inlet valve 19, and the heating medium valve 17. This not only improves the efficiency and stability of the dissolution process but also reduces the labor intensity of operators, providing strong support for the automated and intelligent operation of the copper electrolysis additive addition system 1.

[0049] According to some embodiments of the present invention, the electronic control device 14 is configured to instruct the replenishment of a corresponding type of additive based on the dissolution process of the additive in the additive dissolution tank 111.

[0050] Based on the needs of the dissolving process, the electronic control device 14 can determine whether a specific additive needs to be added and issue instructions to the operator through appropriate means (such as text prompts on the display screen, audible alarms, etc.). Instructions include, but are not limited to, the type and quantity of additive to be added, and the timing of addition. Through the intelligent instructions of the electronic control device 14, operators can more precisely control the addition of additives, thereby improving the efficiency and accuracy of the dissolving process and reducing waste and errors.

[0051] The following describes the additive dissolution process in a copper electrolysis additive addition system 1 according to an embodiment of the present invention.

[0052] When the system starts, the electronic control device 14 controls the water valve to open and begin replenishing water to the additive dissolving tank 111. When the liquid level reaches the preset initial water replenishment level, the electronic control device 14 controls the water valve to close, stopping the water replenishment, so that there is enough water in the additive dissolving tank 111 for the subsequent dissolving process.

[0053] After the initial water replenishment is completed, the electronic control device 14 controls the stirring device 15 to start. The stirring device 15 operates at a preset speed to ensure that the additive can be fully and evenly dissolved in the water.

[0054] Next, the electronic control device 14 will prompt the operator to add materials according to a preset program. First, the electronic control device 14 prompts the operator to add gelatin. After the operator adds gelatin, the water in the additive dissolving tank 111 begins to dissolve the gelatin. When the dissolving time reaches the set time, the electronic control device 14 prompts the operator to add thiourea. After the operator adds thiourea, the water in the additive dissolving tank 111 begins to dissolve the thiourea. When the thiourea dissolving time reaches the set time, the electronic control device 14 continues to prompt the operator to add avitamin. After the operator adds avitamin, the water in the additive dissolving tank 111 begins to dissolve the avitamin.

[0055] During the feeding and dissolving process, the electronic control device 14 automatically raises the temperature according to the preset target temperature. The electronic control device 14 controls the opening of the medium valve 17 to heat the medium using the heating medium. The opening degree of the medium valve 17 can be set as needed to control the heating rate. When the preset target temperature is reached, the electronic control device 14 controls the medium valve 17 to close, stopping the heating.

[0056] In the later stages of additive dissolution, the electronic control device 14 controls the water valve to open and automatically replenish water as needed. Similar to the initial water replenishment, by controlling the opening and closing of the water valve, the liquid level in the additive dissolution tank 111 is ensured to be maintained at the preset secondary water replenishment level.

[0057] Throughout the dissolution process, the system continuously monitors heat loss. When the heat loss falls below the preset control temperature target value, the system automatically repeats the heating program to maintain the temperature of the medium, ensuring that the temperature inside the dissolution tank remains within a suitable range and preventing temperature fluctuations from affecting the dissolution effect.

[0058] Once all additives have dissolved and the temperature and liquid level in the additive dissolving tank 111 have reached the preset requirements, the system automatically completes the dissolving process and proceeds to the subsequent addition procedure.

[0059] According to some embodiments of the present invention, the copper electrolysis additive addition system 1 further includes a level detector, which is disposed within the additive dissolving device 11 and adapted to detect the level of the additive dissolving tank 111. By detecting the level of the additive dissolving tank 111, the quantity of additive solution can be monitored in real time. The level detector is communicatively connected to the electronic control device 14 to send level data to the electronic control device 14. After receiving the level data sent by the level detector, the electronic control device 14 can determine and execute corresponding control commands based on the level data. For example, during the water replenishment process, when the level reaches a preset initial water replenishment level, the electronic control device 14 controls the water valve to close, stopping the water replenishment, so that there is sufficient water in the additive dissolving tank 111 for subsequent dissolution processes.

[0060] According to some embodiments of the present invention, such as Figure 1As shown, the copper electrolysis additive addition system 1 also includes an electric valve 20, which is used to control the flow of fluid. The electric valve 20 is electrically driven to open and close, thereby controlling the fluid flow. The electric valve 20 is located upstream of the first metering pump 13, meaning the fluid must pass through the electric valve 20 before reaching the first metering pump 13. This allows the electronic control device 14 to control the flow of fluid to the first metering pump 13 by controlling the opening and closing of the electric valve 20. The electric valve 20 is communicatively connected to the electronic control device 14. The electronic control device 14 can send control commands to the electric valve 20 to instruct it to open or close, reducing manual operation and improving the system's automation and operating efficiency.

[0061] According to some embodiments of the present invention, the electronic control device 14 is configured to control the operating status of the stirring device 15, the medium valve 17, the first metering valve, and the electric valve 20 based on the liquid level data detected by the liquid level detector after the first metering valve and the electric valve 20 are opened.

[0062] After the electronic control device 14 controls the opening of the first metering valve and the electric valve 20, the additive solution in the additive dissolving tank 111 begins to be transferred to the electrolytic cell. During the transfer process, the liquid level in the additive dissolving tank 111 is detected by the liquid level detector and the liquid level data is sent to the electronic control device 14. As the additive solution flows out, the electronic control device 14 controls the operating status of the stirring device 15, the medium valve 17, the first metering valve, and the electric valve 20 according to the changes in the liquid level data, realizing the stable and precise transfer of the additive solution from the dissolving tank to the electrolytic cell, providing a strong guarantee for the efficient and high-quality operation of the copper electrolysis process.

[0063] The following describes the conveying process of the additive solution in the copper electrolysis additive addition system 1 according to an embodiment of the present invention.

[0064] When the system receives an instruction to add the additive solution to the electrolytic cell, the electronic control device 14 first controls the electric valve 20 to open, so that the additive solution can smoothly pass through the first metering valve into the electrolytic cell.

[0065] Ten seconds after the electric valve 20 is opened, the electronic control device 14 controls the first metering pump 13 to start. The operating frequency of the first metering pump 13 is controlled by the electronic control device 14 and is automatically adjusted to meet the preset flow target value. Once the target flow rate is reached, the first metering pump 13 will operate stably, continuously and uniformly adding the additive solution to the electrolytic cell.

[0066] As the additive solution is continuously added, the liquid level in the additive dissolving tank 111 will continuously decrease. The liquid level in the additive dissolving tank 111 is detected by a liquid level detector. When the liquid level reaches the preset set value, the electronic control device 14 will control the stirring device 15 to stop operating.

[0067] At the same time, when the liquid level in the additive dissolving tank 111 reaches the set value, the electronic control device 14 will also control the medium valve 17 to close.

[0068] After confirming that the additive solution has been fully added to the electrolytic cell, the electronic control device 14 will control the first metering pump 13 to stop operating.

[0069] Ten seconds after the first metering pump 13 stops running, the electronic control device 14 will control the electric valve 20 to close.

[0070] The above-described additive solution delivery process enables continuous addition of the additive solution, ensuring its efficient utilization.

[0071] According to some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the copper electrolysis additive addition system 1 also includes a hydrochloric acid addition device 21, which is used for storing and supplying hydrochloric acid. A hydrochloric acid tank is formed within the hydrochloric acid addition device 21 for storing hydrochloric acid solution.

[0072] The copper electrolysis additive addition system 1 also includes a fourth transmission pipeline 22 and a second metering pump 23. The fourth transmission pipeline 22 is used to transfer hydrochloric acid from the hydrochloric acid tank to the electrolytic cell to meet the hydrochloric acid requirements during electrolysis. The second metering pump 23 is used to control the amount of hydrochloric acid transferred. One end of the fourth transmission pipeline 22 is connected to the electrolytic cell, and the other end is connected to the outlet of the hydrochloric acid addition device 21, allowing the fourth transmission pipeline 22 to transport the hydrochloric acid solution from the hydrochloric acid tank to the electrolytic cell. The second metering pump 23 is located in the fourth transmission pipeline 22 to regulate the flow rate of the hydrochloric acid solution transferred through the fourth transmission pipeline 22. Through a communication connection between the second metering pump 23 and the electronic control device 14, the electronic control device 14 can control the operation of the second metering pump 23, thereby adjusting the hydrochloric acid transfer rate as needed.

[0073] According to some embodiments of the present invention, the copper electrolysis additive addition system 1 further includes a hydrochloric acid stock solution source, a fifth transmission pipeline, and a third metering pump. The hydrochloric acid stock solution source serves as the supply source of hydrochloric acid stock solution, ensuring a stable supply of hydrochloric acid. The fifth transmission pipeline is used to transport the hydrochloric acid stock solution. One end of the fifth transmission pipeline is connected to the hydrochloric acid stock solution source, and the other end is connected to the inlet of the hydrochloric acid addition device 21, thereby allowing the hydrochloric acid stock solution to be smoothly transported into the hydrochloric acid addition device 21 via the fifth transmission pipeline. The third metering pump is located in the fifth transmission pipeline and is communicatively connected to the electronic control device 14, allowing the electronic control device 14 to control the third metering pump, thereby regulating the flow rate of the hydrochloric acid stock solution in the fifth transmission pipeline.

[0074] According to some embodiments of the present invention, the copper electrolysis additive addition system 1 further includes an acid inlet valve, which is located upstream of the third metering pump and is communicatively connected to the electronic control device 14. The hydrochloric acid stock solution must pass through the acid inlet valve to flow to the third metering pump. Through the communicative connection between the acid inlet valve and the electronic control device 14, the electronic control device 14 can control the opening and closing state of the acid inlet valve, thereby achieving fine regulation of the hydrochloric acid stock solution before it flows into the third metering pump.

[0075] According to some embodiments of the present invention, the copper electrolysis additive addition system 1 further includes a water source, a sixth transmission pipeline, and an inlet valve 19. The water source serves as the water supply source, ensuring a stable water supply. One end of the sixth transmission pipeline is connected to the water source, and the other end is connected to the inlet of the hydrochloric acid addition device 21, allowing water from the water source to be transported to the hydrochloric acid addition device 21 through the sixth transmission pipeline. The inlet valve 19 is located on the sixth transmission pipeline and is communicatively connected to the electronic control device 14, enabling the electronic control device 14 to control the opening and closing state of the inlet valve 19 in real time, thereby regulating the amount of water entering the hydrochloric acid addition device 21.

[0076] The following is for reference. Figure 4 A control method for a copper electrolysis additive addition system 1 for any of the above-mentioned uses is described according to the present invention.

[0077] like Figure 4 As shown, according to the control method of the present invention, based on the dissolution process and / or the process of the solution being transported to the electrolytic cell, the electronic control device 14 determines and executes corresponding control commands. The control commands include, but are not limited to, adjusting the flow rate of the additive solution, indicating the replenishment of the corresponding type of additive, controlling the operating status of the stirring system, controlling the operating status of the heating system, and controlling the on / off status of the relevant valves.

[0078] According to the control method of the present invention, the operation of the copper electrolysis additive addition system 1 is highly automated and intelligent. Throughout the entire process of additive dissolution and the delivery of the additive solution to the electrolytic cell, the electronic control device 14 can accurately determine and execute corresponding control commands in real time based on the dissolution progress and / or the solution delivery process to the electrolytic cell.

[0079] Control commands include, but are not limited to:

[0080] Adjusting the flow rate of the additive solution: By controlling the first metering pump 13, the electronic control device 14 can ensure that the additive solution is added to the electrolytic cell uniformly and continuously according to the preset flow target value, which avoids waste and ensures the stability of the electrolysis process.

[0081] Instructions to replenish the corresponding types of additives: During the dissolution process, the electronic control device 14 will prompt the operator to add materials according to the preset program, ensuring that additives such as gelatin, thiourea, and avitin are added correctly in sequence and at specified time intervals, thereby optimizing the dissolution effect and the quality of electrolytic copper.

[0082] Controlling the operating status of the stirring system: By controlling the opening and closing of the stirring device 15 and adjusting its speed, the electronic control device 14 can ensure that the additive is fully and evenly dissolved in the water, thereby improving the dissolution efficiency.
