Description

Technical Field

[0001] This utility model relates to the field of copper electrolyte purification technology, specifically an automatic flushing device for electrowinning tanks. Background Technology

[0002] During the copper electrowinning process, a large amount of oxygen is continuously released from the anode surface due to the oxygen evolution reaction (4OH-→O2↑+2H2O+4e-), which leads to a significant increase in the concentration of sulfuric acid mist on the electrolyte surface. A tank cover needs to be installed above the electrowinning tank. Although this effectively reduces the escape of acid mist, it also causes a large amount of crystals and impurities to adhere to the conductor and anode plates. The accumulation of crystals and impurities not only increases the circuit contact resistance, leading to increased power loss, but may also cause serious problems such as short circuits on the plates and decreased current efficiency. The tank cover needs to be opened regularly for rinsing.

[0003] Currently, electrolysis plants both domestically and internationally generally adopt a manual operation mode of dragging water pipes to rinse the busbars and electrode plates. This mode has some significant problems. Not only does it require a large amount of manpower, but the high concentration of acid mist released when the tank cover is opened further deteriorates the workshop working environment. In addition, manual rinsing has problems such as uneven water flow coverage and blind spots, resulting in low rinsing efficiency. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an automatic flushing device for electrodeposition tank, which realizes automatic flushing of the conductive busbar and anode and cathode plates in electrodeposition tank by adjusting the solenoid valve.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic flushing device for an electrowinning tank, comprising three conductive bars, anode and cathode plates fixedly installed on the left side of the three conductive bars, and groove sides fixedly connected to the upper and lower sides of the three conductive bars, with pipes installed on the sides of the two groove sides that are far apart from each other. Five branch pipes are fixedly connected to each of the two pipes. The opposite ends of the ten branch pipes extend into the interior of the trench, and the opposite ends of the ten branch pipes extend out of the two trenches respectively. The ten branch pipes are all fixedly connected to the opposite ends of the corrugated hoses, and the ten corrugated hoses are all equipped with nozzles. Solenoid valves are installed on both pipes, and adjustment mechanisms are provided on both of the groove sides. The flushing position of the nozzles can be changed through the adjustment mechanisms. The two adjustment mechanisms are arranged symmetrically above and below, and the following description focuses on the lower adjustment mechanism. The adjustment mechanism includes an adjustment frame, a moving block, two limit slides, two limit sliders, an electric push rod, and two limit rods.

[0006] Preferably, the adjusting frame is fixedly connected to the upper side of the groove, and the moving block is slidably connected inside the adjusting frame; The upper ends of the five corrugated hoses all pass through the moving block, and the moving block is fixedly connected to the five nozzles.

[0007] Preferably, the two limiting grooves are respectively formed on the front wall and the rear wall of the adjusting frame, and the two limiting sliders are respectively fixedly connected to the front and rear sides of the moving block; Two limit sliders are slidably connected inside two limit grooves, and an electric push rod is fixedly connected to the left side of the adjustment frame.

[0008] Preferably, the output end of the electric push rod is fixedly connected to a telescopic rod, and the right end of the telescopic rod slides into the interior of the adjustment frame.

[0009] Preferably, the right end of the telescopic rod is fixedly connected to the moving block, and both limiting rods are fixedly connected to the left wall of the adjusting frame, with the two limiting rods arranged symmetrically front and back.

[0010] Preferably, the right ends of both limiting rods slide through the moving block, and the right ends of both limiting rods are fixedly connected to the right wall of the adjusting frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) The automatic flushing device for the electrowinning cell not only replaces manual flushing and improves the automation level of the process, but also avoids acid mist escaping caused by opening the cover for flushing, thus purifying the working environment at the production site.

[0012] (2) The automatic flushing device for the electrowinning tank drives the telescopic rod through the electric push rod in the adjustment mechanism, thereby causing the moving block to slide in the adjustment frame. The moving block drives the corrugated hose and nozzle to move, which can flexibly change the flushing position of the nozzle. This allows the flushing position to be precisely adjusted according to the degree of dirt in different areas of the electrowinning tank and the operational requirements, thereby improving the targeting and effectiveness of the flushing.

[0019] Please see Figure 1-5This utility model provides a new technical solution: an automatic flushing device for an electrolytic cell, comprising three conductive bars 1, with anode and cathode plates 2 fixedly installed on the left side of the three conductive bars 1, and groove sides 3 fixedly connected to the upper and lower sides of the three conductive bars 1. Pipes 4 are installed on the opposite sides of the two groove sides 3, and five branch pipes are fixedly connected to each of the two pipes 4. The opposite ends of the ten branch pipes extend into the interior of the groove side 3, and the opposite ends of the ten branch pipes extend out of the two groove sides 3 respectively. Corrugated hoses 6 are fixedly connected to the opposite ends of the ten branch pipes, and nozzles 5 are installed on the opposite ends of the ten corrugated hoses 6. Solenoid valves 7 are installed on each of the two pipes 4, and adjustment mechanisms are provided on each of the two groove sides 3. The flushing position of the nozzles 5 can be changed through the adjustment mechanisms. The two adjustment mechanisms are arranged symmetrically, and the following description focuses on the lower adjustment mechanism. The adjustment mechanism includes an adjustment frame 8, a moving block 9, two limiting slide grooves 10, two limiting sliders 11, an electric push rod 12, and two limiting rods 14.

[0020] The adjusting frame 8 is fixedly connected to the upper side of the groove 3. The moving block 9 is slidably connected to the inside of the adjusting frame 8. The upper ends of the five corrugated hoses 6 all pass through the moving block 9. The moving block 9 is fixedly connected to the five nozzles 5. Two limiting grooves 10 are respectively opened on the front and rear walls of the adjusting frame 8. Two limiting sliders 11 are respectively fixedly connected to the front and rear sides of the moving block 9. The two limiting sliders 11 are respectively slidably connected to the inside of the two limiting grooves 10. The electric push rod 12 is fixedly connected to the left side of the adjusting frame 8. The output end of the electric push rod 12 is fixedly connected to the telescopic rod 13. The right end of the telescopic rod 13 slides into the inside of the adjusting frame 8. The right end of the telescopic rod 13 is fixedly connected to the moving block 9. Two limiting rods 14 are fixedly connected to the left wall of the adjusting frame 8. The two limiting rods 14 are symmetrically arranged front and back. The right ends of the two limiting rods 14 slide through the moving block 9. The right ends of the two limiting rods 14 are fixedly connected to the right wall of the adjusting frame 8.

[0021] The tank wall 3 is made of fiberglass, the pipe 4 is made of PE pipe, the nozzle 5 is a flat nozzle with a fan-shaped water outlet. The fan-shaped water outlet of the nozzle 5 located above the conductive bar is perpendicular to the conductive bar. The fan-shaped water outlet of the nozzle 5 located at the anode and cathode plate position in the middle of the electrolytic cell has an angle of 45° with the horizontal liquid surface. The solenoid valve 7 is connected to the end of the pipe 4 and connected to the computer.

[0022] Example 1: As Figure 4 As shown, when the computer sends a flushing signal, the solenoid valve 7 opens, and hot water flows through the pipe 4 to the nozzle 5 for flushing. The nozzle 5, located at the conductive bar, discharges water perpendicularly to the conductive bar. After flushing, the conductive bar is clean and free of crystals and impurities.

[0023] Example 2: Figure 5As shown, when the computer sends a flushing signal, the solenoid valve 7 opens, and hot water flows through the pipe 4 to the nozzle 5 for flushing. The nozzle 5, located at the position of the anode and cathode plates in the middle of the electrolytic cell, has a fan-shaped water outlet direction with an angle of 45° to the horizontal liquid surface (opposite on both sides). The anode and cathode plates are clean after flushing, without crystals or impurities.

[0024] During the rinsing process, the electric push rod 12 is activated, and its output end drives the telescopic rod 13 to extend and retract. Because the right end of the telescopic rod 13 is fixedly connected to the moving block 9, the telescopic rod 13 will cause the moving block 9 to slide inside the adjusting frame 8 when it extends and retracts. The limiting sliders 11 on the front and rear sides of the moving block 9 slide in the limiting grooves 10 on the front and rear walls of the adjusting frame 8, respectively, to limit and guide the movement, ensuring that the moving block 9 moves in a straight line. At the same time, two limiting rods 14 pass through the moving block 9, and the two ends of the limiting rods 14 are fixed to the left and right walls of the adjusting frame 8, respectively. To further restrict the movement trajectory of the moving block 9 and prevent it from shaking, since the upper ends of the five corrugated hoses 6 pass through the moving block 9 and are fixedly connected to it, the movement of the moving block 9 will drive the corrugated hoses 6 to move, which in turn will drive the nozzles 5 to move, changing the rinsing position of the nozzles 5. This allows for rinsing of all parts of the conductive bar and the anode and cathode plates, avoiding the existence of dead corners. Because the moving block 9 is fixedly connected to the five nozzles 5, the angle of the nozzles 5 will not change when the moving block 9 drives the nozzles 5 to move, ensuring the rinsing effect.

[0025] Structural Description: Conductive Busbar 1: There are three conductive busbars 1 in total. The three conductive busbars 1 are the core conductive components of the electrodeposition cell. The left side of the three conductive busbars 1 is used to fix and install the anode and cathode plates 2. The upper and lower sides of the three conductive busbars 1 are respectively fixedly connected to the cell wall 3. The three conductive busbars 1 provide a conductive path for the electrodeposition process and also serve to support the anode and cathode plates 2 and the cell wall 3.

[0026] Anode and cathode plates 2: Anode and cathode plates 2 are fixedly installed on the left side of the three conductive bars 1. Anode and cathode plates 2 are the core working components for the deposition or dissolution of substances in the electrodeposition reaction. The surface of anode and cathode plates 2 needs to be rinsed by nozzle 5 to remove surface crystals and impurities, so as to ensure the efficiency of the electrodeposition reaction.

[0027] Channel 3: There are two channels 3, which are fixedly connected to the upper and lower sides of the three conductive bars 1 respectively. The channel 3 is made of fiberglass. One side of the channel 3 is used to install the pipe 4, and the inside of the channel 3 is for the branch pipe to pass through. The channel 3 serves as the frame of the device, supporting the pipe 4, adjustment mechanism and other components. At the same time, the fiberglass material gives the channel 3 corrosion resistance and high strength, making it suitable for the working environment of the electrowinning cell.

[0028] Pipeline 4: There are two pipelines 4, which are installed on opposite sides of the two tank walls 3. The material of pipeline 4 is PE pipe. The end of pipeline 4 is connected to solenoid valve 7. Five branch pipes are fixedly connected to pipeline 4. Pipeline 4 is the main channel for conveying the flushing medium, which is distributed to each branch pipe. The PE pipe material gives pipeline 4 the characteristics of chemical corrosion resistance and good flexibility, making it suitable for conveying flushing liquid.

[0029] Nozzle 5: There are ten nozzles 5 in total. The ten nozzles 5 are connected to ten branch pipes through corrugated hoses 6. The nozzles 5 are flat nozzles. The water outlet of the nozzles 5 is a fan-shaped water outlet. The nozzles 5 located above the conductive bar 1 have a fan-shaped water outlet direction perpendicular to the conductive bar 1, which is used to rinse the crystals and impurities on the surface of the conductive bar 1. The nozzles 5 located in the middle of the anode and cathode plates 2 of the electrolytic cell have a fan-shaped water outlet direction at an angle of 45° with the horizontal liquid surface, which is used to rinse the crystals and impurities on the surface of the anode and cathode plates 2.

[0030] Corrugated hose 6: There are ten corrugated hoses 6 in total. One end of each of the ten corrugated hoses 6 is fixedly connected to the opposite end of the ten branch pipes, and the other end of each of the ten corrugated hoses 6 is fixedly connected to the ten nozzles 5. The upper ends of five of the corrugated hoses 6 pass through the moving block 9 and are fixedly connected to the moving block 9. The corrugated hoses 6 are used to connect the branch pipes and the nozzles 5 and to transport the flushing medium. At the same time, the corrugated hoses 6 are telescopic and flexible, which can move the nozzles 5 to change position in coordination with the movement of the moving block 9 without affecting the transport of the medium.

[0031] Solenoid valve 7: There are two solenoid valves 7, which are installed on two pipes 4 respectively. The solenoid valve 7 is connected to the end of the pipe 4 and to the computer. The solenoid valve 7 is the control switch for the flushing medium. When the computer gives a flushing signal, the solenoid valve 7 opens, allowing the flushing medium to be delivered to the nozzle 5 through the pipe 4. When the flushing ends, the solenoid valve 7 closes, cutting off the medium delivery and realizing automatic control of the flushing process.

[0032] Adjustment Frame 8: There are two adjustment frames 8. The two adjustment frames 8 are fixedly connected to the upper side of the two groove sides 3 respectively. The adjustment frame 8 is the main frame of the adjustment mechanism. The interior of the adjustment frame 8 is for the sliding block 9. The front wall and rear wall of the adjustment frame 8 are provided with limiting slide grooves 10. The left wall of the adjustment frame 8 is fixedly connected to the electric push rod 12 and the limiting rod 14, and the right wall of the adjustment frame 8 is fixedly connected to the limiting rod 14, providing installation and operating space for the various components of the adjustment mechanism.

[0033] Moving block 9: Moving block 9 is slidably connected inside the adjusting frame 8. Moving block 9 is fixedly connected to five corrugated hoses 6. Moving block 9 is fixedly connected to the right end of the telescopic rod 13. Moving block 9 slides along the adjusting frame 8 under the drive of telescopic rod 13. When moving, moving block 9 drives the nozzle 5 to change the rinsing position through the corrugated hoses 6. At the same time, moving block 9 plays a role in fixing and supporting the corrugated hoses 6.

[0034] Limiting slide 10: There are two limiting slides 10. The two limiting slides 10 are respectively opened on the front wall and the rear wall of the adjusting frame 8. The limiting slide 10 provides a sliding track for the limiting slider 11, restricts the movement direction of the limiting slider 11, and thus plays a limiting and guiding role in the sliding of the moving block 9, ensuring that the moving block 9 moves in a straight line.

[0035] Limiting slider 11: There are two limiting sliders 11. The two limiting sliders 11 are fixedly connected to the front and rear sides of the moving block 9 respectively. The two limiting sliders 11 are slidably connected inside the two limiting grooves 10 respectively. The limiting sliders 11 move synchronously with the moving block 9. By sliding in the limiting grooves 10, they cooperate with the limiting grooves 10 to limit the movement trajectory of the moving block 9 and prevent the moving block 9 from deviating or shaking when sliding.

[0036] Electric push rod 12: The electric push rod 12 is fixedly connected to the left side of the adjustment frame 8. The output end of the electric push rod 12 is fixedly connected to the telescopic rod 13. The electric push rod 12 is the power source of the adjustment mechanism. When the electric push rod 12 is started, it drives the telescopic rod 13 to extend and retract through the output end, thereby driving the moving block 9 to slide inside the adjustment frame 8, providing power for the position adjustment of the nozzle 5.

[0037] Telescopic rod 13: The left end of the telescopic rod 13 is fixedly connected to the output end of the electric push rod 12, and the right end of the telescopic rod 13 slides into the interior of the adjustment frame 8 and is fixedly connected to the moving block 9. The telescopic rod 13 is the component that transmits power to the electric push rod 12. Through telescopic movement, it transmits the power of the electric push rod 12 to the moving block 9, causing the moving block 9 to slide along the adjustment frame 8.

[0038] Limiting rod 14: There are two limiting rods 14. Both limiting rods 14 are fixedly connected to the left wall of the adjusting frame 8 and are arranged symmetrically front and back. The right ends of the two limiting rods 14 slide through the moving block 9 and are fixedly connected to the right wall of the adjusting frame 8. The limiting rods 14 further restrict the movement trajectory of the moving block 9, prevent the moving block 9 from swaying up and down or left and right when sliding, and ensure that the moving block 9 moves stably along a straight line.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
