Description

Technical Field

[0001] This utility model relates to the technical field, and more specifically, to an intelligent electrolysis equipment for electrolytic copper production. Background Technology

[0002] Electrolytic copper is a high-purity copper product. It is extracted from crude copper through electrolytic refining and has wide applications in numerous fields such as electrical, electronic, and mechanical manufacturing. When direct current is applied, an oxidation reaction occurs at the anode, where copper atoms in the crude copper lose electrons to become copper ions and enter the electrolyte. Meanwhile, copper ions on the cathode surface gain electrons and become copper atoms, depositing on the cathode surface. At this point, due to the large accumulation of copper ions around the anode and the significant consumption of copper ions around the cathode, concentration polarization occurs, which affects the quality of electrolytic copper.

[0003] Existing technologies often employ mechanical stirring or electrolyte flow displacement to reduce concentration polarization, but these two methods cannot improve the ion concentration differences in the dead zones of the cathode and anode and the microscopic ion concentration differences. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide an intelligent electrolysis equipment for electrolytic copper production.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] Box;

[0007] The electrolyte inlet / outlet mechanism has an inlet pipe located at the top of the tank for drawing in electrolyte, and an outlet pipe located at the bottom of the tank for discharging electrolyte; the electrolyte inlet / outlet mechanism also has a guide column for diverting electrolyte.

[0008] Anode and cathode electrodes are disposed on both sides of the housing and face each other; each anode and cathode electrode has a sensor disposed around the anode and cathode electrode for sensing the concentration of electrolyte ions; it also has a telescopic component disposed below the anode and cathode electrode for extending and retracting the anode and cathode electrode; the telescopic component is provided with a support part around the telescopic component for supporting the telescopic component and stabilizing the electrode.

[0009] The technical solution described above in this application example has at least the following technical effects:

[0010] The anode and cathode electrodes are mounted on a telescopic rod, surrounded by sensors monitoring the concentration of copper ions and other substances. When a large ion difference occurs near the electrodes, leading to concentration polarization, the sensors transmit information to control the telescopic rod's movement, adjusting the distance between the electrodes to even out the electric field and improve electrolyte quantity and efficiency. Because guide tubes are installed near the inlet and outlet pipes, the electrolyte is evenly distributed, maintaining a uniform copper ion concentration. The adjustment of the anode and cathode electrodes and the opening and closing of the inlet and outlet pipes can be fully automated, improving production efficiency.

[0011] In some embodiments, the liquid inlet / outlet mechanism further includes a guide column for receiving electrolyte from the liquid inlet pipe; the outer wall of the guide column is provided with a plurality of holes spaced apart along the axial direction for diverting electrolyte.

[0012] In some embodiments, the anode and cathode electrodes are detachably disposed at the output end of the telescoping device.

[0013] In some embodiments, two or more sensors are provided on the housing.

[0014] In some embodiments, the telescopic device has a driver and a telescopic rod disposed on a housing; the output end of the telescopic rod is connected to a positive and a negative electrode.

[0015] In some embodiments, the support portion has a movable portion disposed on the housing, and a support rod that is movably disposed at one end on the movable portion and movably connected to the telescopic rod at the other end. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 and Figure 3 This application provides an intelligent electrolysis device for copper electrolysis production, comprising a housing 01; an inlet / outlet mechanism 02, having an inlet pipe 03 disposed at the top of the housing 01 for drawing in electrolyte, and an outlet pipe 04 disposed at the bottom of the housing 01 for discharging electrolyte; the inlet / outlet mechanism 02 also has a guide column for electrolyte diversion; an electrode assembly 06, having anode and cathode electrodes 07 disposed opposite to each other on both sides of the housing 01; the electrode assembly 06 has a sensor 08 disposed on the housing 01 for sensing the ion concentration of the electrolyte; and a telescopic device 09 that, based on feedback from the sensor 08, drives the anode and cathode electrodes 07 to move relative to each other, thereby making the current between the anode and cathode electrodes 07 more uniform.

[0023] Understandably, the inlet / outlet mechanism 02 is a component used to control the input and output of the electrolyte. The inlet pipe 03 is the channel for the electrolyte to enter the tank 01, and the outlet pipe 04 is the channel for discharging the electrolyte. These can be, for example, corrosion-resistant rigid pipes or corrosion-resistant flexible pipes, etc., but are not limited to these. The guide column connects the inlet pipe 03 and the outlet pipe 04. To prevent electrolyte leakage, a sealed connection should be used between the guide column and the inlet pipe 03 and the outlet pipe 04. For example, the connection between the guide column and the inlet pipe 03 and the outlet pipe 04 can be a detachable transition installation, or a sealing ring can be used to seal the connection, etc., but are not limited to these. The anode and cathode electrodes 07 are crude copper plates and pure copper sheets used for electrolytic pure copper, which are existing technologies and will not be described in detail. Sensors 08, positioned around the anode and cathode electrodes 07, are used for real-time monitoring of components such as copper ions in the electrolyte. These sensors can be, for example, electrochemical sensors or spectroscopic sensors, but are not limited to these. Telescopic components are used to move the anode and cathode electrodes 07. These can be, for example, a screw-nut mechanism or an electric push rod mechanism, but are not limited to these. Support parts 10 ensure the stability of the anode and cathode electrodes 07 during movement. These can be, for example, a column-type support structure or a frame-type support structure, but are not limited to these.

[0024] As can be seen from the above, since a telescopic rod 11 that can move the anode and cathode electrodes 07 has been added to the electrode assembly 06, when the concentration of copper ions and other substances around the anode and cathode electrodes 07 increases or decreases, the telescopic rod 11 changes the distance between the anode and cathode electrodes 07, and at the same time promotes the flow of electrolyte between the anode and cathode electrodes 07. The redistribution of copper ions and other substances avoids the concentration polarization phenomenon. Meanwhile, the setting of the support rod 13 ensures the stability of the anode and cathode electrodes 07 during the movement process.

[0025] As is known, in some embodiments, please refer to Figure 3 The liquid inlet / outlet mechanism 02 also includes a guide column for receiving the electrolyte from the liquid inlet pipe 03; the outer wall of the guide column is provided with a number of holes spaced apart along the axial direction for diverting the electrolyte.

[0026] Understandably, the guide column is connected to the inlet pipe 03 and serves to receive the electrolyte introduced through it. Since the guide column is constantly immersed in a highly corrosive electrolyte, it should be a highly corrosion-resistant and durable insulating rigid pipe, such as a rigid polyvinyl chloride (UPVC) pipe or a polypropylene (PP) pipe, but not limited to these materials. The holes allow the electrolyte in the guide column 05 to be evenly distributed into the housing 01. For example, these holes could be multiple holes evenly spaced axially on the outer wall of the guide column 05, or multiple holes unevenly spaced, but not limited to these methods.

[0027] With this configuration, the guide column and its components can receive and distribute the electrolyte, preventing uneven ion concentration of the electrolyte in the tank 01. At the same time, the corrosion-resistant material used for the guide column not only prevents the guide column from contaminating the electrolyte due to corrosion, but also ensures that the guide column can be used for a long time, avoiding frequent replacements.

[0028] As is known, in some embodiments, please refer to Figure 3 The positive and negative electrodes 07 are detachably mounted at the output end of the telescopic device 09.

[0029] It is understandable that the anode and cathode are components that need to be replaced frequently during production. For example, the anode and cathode 07 can be installed on the telescopic device 09 by screwing them on, or the telescopic device 09 can be equipped with a clamping plate or jaws for holding the anode and cathode 07, but it is not limited to these.

[0030] With this setup, the positive and negative electrodes 07 can be replaced at any time to ensure the electrolysis process continues.

[0031] As is known, in some embodiments, please refer to Figure 4 Two or more sensors 08 are arranged around the housing 01.

[0032] Understandably, sensor 08 is a component that senses changes in the concentration of substances such as copper ions around the anode and cathode electrodes 07. The distribution and number of sensors 08 affect the sensitivity of the sensor to detect concentration changes. For example, only one sensor 08 can be set near the anode and cathode electrodes 07, or multiple sensors 08 can be set around the anode and cathode electrodes 07 on the housing 01, etc., but it is not limited to this.

[0033] With this setup, multiple sensors 08 can perform concentration detection comparisons, more sensitively detecting changes in electrolyte concentration near the anode and cathode electrodes 07, thus improving the reliability of monitoring.

[0034] As is known, in some embodiments, please refer to Figure 3 The telescopic device 09 has a driver 12 and a telescopic rod 11 mounted on the housing 01; the output end of the telescopic rod 11 is connected to the positive and negative electrodes 07.

[0035] Understandably, the driver 12 provides power to the telescopic rod 11, causing the telescopic rod 11 to move the positive and negative electrodes 07. For example, it can be an electric push rod structure, or a pressure pump plus push rod structure, etc., but is not limited to these.

[0036] As is known, in some embodiments, please refer to Figure 4 The support part 10 has a movable part 14 disposed on the housing 01, and a support rod 13 that is movably disposed on the movable part 14 at one end and movably connected to the telescopic rod 11 at the other end.

[0037] Understandably, the support rod 13 is used to stabilize the anode and cathode electrodes 07, ensuring their stability as they move with the telescopic rod 11. For example, the support rod 13 could be multiple columns parallel to the telescopic rod 11, connected to the anode and cathode electrodes 07, or it could be a frame-type support structure, but it is not limited to these. Since the movement of the telescopic rod 11 will cause the support rod 13 to move, the support part 10 needs to be equipped with a movable part 14 that allows the support rod 13 to move with the telescopic rod 11. Simultaneously, the connection points between the support rod 13 and the movable part 14, and between the support rod 13 and the telescopic rod 11, should be movable connections. For example, the movable part 14 could be a sliding mechanism, with the support rod 13 hinged to the slider 15 in the sliding mechanism and to the telescopic rod 11; or it could be a rolling mechanism, with the support rod 13 hinged to the slider 15 in the sliding mechanism and to the telescopic rod 11, etc., but it is not limited to these. Furthermore, the support part 10 needs to have at least two such parts to stabilize the anode and cathode electrodes 07.

[0038] This configuration, with multiple support rods 13 and moving parts 14 working together, allows the support part 10 to better stabilize the anode and cathode electrodes 07, preventing displacement of the electrode plates due to movement and affecting electrode quality. As can be seen from the above, when the electrolytic cell starts working, the anode and cathode electrodes begin to operate, gradually consuming internal copper ions. When the sensor detects a deviation in the electrolyte concentration near the anode and cathode electrodes from the set value, it transmits a command to the telescopic component. The telescopic component then moves the anode and cathode electrodes, changing the potential difference between them and ensuring normal electrolysis.

[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
