Description

Technical Field

[0001] This utility model belongs to the field of copper electrolytic refining technology, specifically relating to an automatic liquid level adjustment device for a buoyancy-type electrolytic cell. Background Technology

[0002] In the copper electrolysis production process, copper ions are deposited on the cathode plate. The liquid level of the electrolyte in the electrolytic cell determines the metal adsorption height. If the adsorption is too high, the electrolyzed metal is difficult to peel off; if the adsorption is too low, it will lead to a reduction in production capacity. At the same time, in order to adapt to the operation of the automatic cathode plate stripping unit, it is necessary to change the liquid level at the cathode plate to adjust the thickness of the electrolyzed copper on the cathode plate, so that the electrolyzed copper is thinner at the top and thicker at the bottom, which facilitates the smooth operation of the subsequent automatic stripping unit and reduces the difficulty of peeling off the electrolyzed copper. Therefore, in the copper electrolysis production process, it is necessary to frequently adjust the liquid level of the electrolytic cell to produce multiple different liquid level heights.

[0003] Currently, most electrolytic cell liquid level adjustment methods achieve liquid level changes by manually adjusting the liquid outlet or inlet speed. For example, by installing a sleeve on the liquid outlet pipe to extend the height of the outlet pipe, the liquid level in the electrolytic cell can be adjusted. On the one hand, it requires manual disassembly and reassembly of the sleeve, which is quite troublesome. On the other hand, the liquid level is fixed after adjustment and cannot achieve automatic reciprocating rise and fall of the liquid level. Summary of the Invention

[0004] This invention addresses the problem that current electrolytic cell level adjustment methods often rely on manual adjustment of the liquid outlet or inlet speed, which is cumbersome and results in a fixed liquid level after adjustment, making automatic reciprocating rise and fall impossible. It provides a buoyancy-based automatic electrolytic cell level adjustment device. By utilizing the buoyancy of a float ball within the electrolytic cell, the device adjusts the sealing and opening of the outlet pipe, thereby automatically adjusting the liquid level. This reduces manual intervention, ensures optimal precipitation, and facilitates subsequent electrolytic copper stripping.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An automatic liquid level adjustment device for a buoyancy-type electrolytic cell is installed on the outlet pipe of the electrolytic cell, which is located on the bottom surface of the cell. The device includes a limiting mechanism fixed above the outlet pipe, within which a buoyancy mechanism is slidably mounted. The buoyancy mechanism rises under the buoyancy of the liquid in the electrolytic cell. A cap, conical in shape with a downward protrusion, is connected to the lower end of the buoyancy mechanism. The upper part of the cap seals the outlet pipe opening. By sealing the outlet pipe, the liquid level in the electrolytic cell rises. This rise causes the buoyancy mechanism to lift the cap, opening the outlet pipe. When the outflow exceeds the inflow, the liquid level drops, and the cap falls back down to seal the outlet pipe. This continuous rise and fall of the liquid level allows for automatic adjustment of the liquid level in the electrolytic cell without manual intervention.

[0007] Preferably, the limiting mechanism includes a limiting cylinder and two first guide rails disposed opposite to each other on the limiting cylinder, and a protrusion is provided in the middle of the first guide rail along the circumference of the limiting cylinder; the buoyancy mechanism includes a float and a float ball, the lower end of the float is fixedly connected to a plug, the float is threaded through the float ball, and two limiting rods are fixedly disposed on the outside of the float ball, the ends of the two limiting rods are respectively slidably disposed in the two first guide rails and correspond to the first guide rails, the first guide rails guide and limit the movement of the float ball, and the float ball drives the plug to rise and fall with the liquid level in the electrolytic cell.

[0008] Preferably, two elastic elements are arranged opposite each other on the outer side of the float. The elastic elements are slidably connected to the limiting cylinder, and the float is kept at the central axis position of the limiting cylinder by the elastic elements.

[0009] Preferably, the limiting cylinder is provided with a second guide rail, and each second guide rail is provided with a slider that slides up and down. The two elastic elements are respectively fixedly connected to the two sliders, and the sliders guide the elastic elements to rise and fall, so as to prevent them from rotating in the circumferential direction.

[0010] Preferably, the elastic element is a spring, and when the float is located on the central axis of the limiting cylinder, the two springs have the same elastic force.

[0011] Preferably, a tube is fixedly installed inside the limiting cylinder, and the tube is sleeved on the float above the float ball. The inner diameter of the tube is larger than the diameter of the float ball, and the tube limits the movement of the float ball.

[0012] Preferably, the upper end of the float is threadedly connected to an adjustment knob after extending out of the tube. By rotating the adjustment knob, the position of the float on the float can be adjusted, thereby adjusting the upper and lower limits of the lifting height of the float and the plug.

[0013] Preferably, the lower end of the limiting cylinder is fixedly connected to a plurality of spaced fixing rods, the lower end of which is detachably connected to the outside of the liquid outlet pipe, and the limiting cylinder is supported by the fixing rods.

[0014] Preferably, an annular protrusion is fixedly provided on the outer side of the upper end of the plug, and the outer diameter of the annular protrusion is larger than the inner diameter of the liquid outlet pipe to ensure that the liquid outlet pipe is completely blocked when the plug falls.

[0015] The beneficial effects of this utility model through the above technical solution are as follows:

[0016] 1. This utility model uses a plug to seal the outlet pipe, which raises the liquid level in the electrolytic cell. The buoyancy of the plug causes the float to rise with the plug, opening the outlet pipe and causing the liquid level to drop. Under the weight of the float and the plug, the plug falls back down to seal the outlet pipe, causing the liquid level in the electrolytic cell to continuously rise and fall in a cycle. The whole process does not require frequent manual operation or even manual intervention.

[0017] 2. This utility model adjusts the position of the float on the float rod by rotating the adjustment knob, thereby adjusting the upper and lower limits of the lifting height of the float and the plug, and thus realizing the adjustment of the upper and lower limits of the liquid level in the electrolytic cell.

[0018] 3. This utility model features a protrusion in the middle of the first guide rail, along with two elastic elements. When the float rises or falls to the point where the limiting rod contacts the protrusion, the protrusion blocks the float from rising or falling, causing the liquid level to continue to rise or fall until the accumulated buoyancy overcomes the elastic force of the elastic elements. At this point, the limiting rod passes around the protrusion and continues to rise, and the float and the plug continue to rise. Alternatively, when the weight of the float and the plug overcomes the resistance of the elastic elements, the limiting rod passes around the protrusion and continues to fall, and the float and the plug continue to fall. Simultaneously, the two opposing elastic elements ensure that the limiting rod returns to its original position on the central axis of the limiting cylinder after passing around the protrusion, thus ensuring the stability of the liquid level rise and fall.

[0019] 4. By setting a plug with a hollow conical structure with an upper opening, this utility model allows some electrolyte to remain inside the plug when the liquid level in the electrolytic cell drops, increasing the weight of the plug and ensuring that the float and plug can smoothly overcome the elastic force of the elastic element and continue to descend.

[0020] 5. This utility model uses two oppositely arranged elastic elements to limit the rotation of the float, so that when the adjustment knob is turned, the float moves up and down along the float rod to adjust the upper and lower limits of the liquid level. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0027] like Figures 1-4 As shown, this embodiment provides a buoyancy-type automatic liquid level adjustment device for an electrolytic cell, which is installed on the outlet pipe 1 of the electrolytic cell. The outlet pipe 1 is located on the bottom surface of the electrolytic cell. When the liquid level in the electrolytic cell is higher than the upper end of the outlet pipe 1, the electrolyte is discharged from the outlet pipe 1. The device includes a limiting mechanism fixedly installed above the outlet pipe 1. A buoyancy mechanism is slidably installed inside the limiting mechanism. The buoyancy mechanism rises under the buoyancy of the liquid in the electrolytic cell. A plug 2 is connected to the lower end of the buoyancy mechanism. The plug 2 is conical with its protrusion facing downwards. The upper part of the plug 2 blocks the opening of the outlet pipe 1. Specifically, the plug 2 is a hollow hemispherical structure with an opening on its upper side. An annular protrusion 15 is fixedly provided on the outer side of the upper end of the plug 2. The outer diameter of the annular protrusion 15 is larger than the inner diameter of the outlet pipe 1. When the plug 2 is located inside the outlet pipe 1 and the lower side of the annular protrusion 15 contacts the upper end face of the outlet pipe 1, the outlet pipe 1 is blocked, and the electrolyte cannot be discharged, thereby increasing the liquid level in the electrolytic cell.

[0028] The buoyancy mechanism includes a float 6 and a float 7. The lower end of the float 6 is fixedly connected to the plug 2, and the float 6 is threaded through the float 7. Specifically, the float 7 is a spherical structure made of PP foam material. Furthermore, the float 7 is a hollow spherical structure. When the electrolyte is submerged in the float 7, under the action of buoyancy, the float 7 and the plug 2 rise, opening the outlet pipe 1. The electrolyte is discharged from the outlet pipe 1 into the electrolytic cell, and the liquid level in the electrolytic cell drops.

[0029] The limiting mechanism includes a limiting cylinder 3 and two first guide rails 4 arranged opposite to each other on the limiting cylinder 3. A protrusion 5 is provided in the middle of the first guide rail 4 along the circumference of the limiting cylinder 3. Two limiting rods 8 are fixedly provided on the outside of the float 7. The ends of the two limiting rods 8 are slidably arranged in the two first guide rails 4 and correspond to the first guide rails 4. The first guide rails 4 guide and limit the limiting rods 8, so that the guide rods 8 can rise and fall smoothly.

[0030] Two elastic elements 9 are arranged opposite each other on the outer side of the float 7. The elastic elements 9 are springs. The elastic elements 9 are slidably connected to the limiting cylinder 3. Specifically, the limiting cylinder 3 is provided with a second guide rail 10. Each second guide rail 10 is provided with a slider 11 that slides up and down. The two elastic elements 9 are fixedly connected to the two sliders 11 respectively. On the one hand, the spring limits the rotation of the float 7. On the other hand, it ensures that the float 7 is located at the circumferential center of the limiting cylinder 3. At this time, the limiting rod 8 corresponds vertically to the protrusion 5.

[0031] As one possible implementation method, such as Figure 1-2 As shown, the width of the first guide rail 4 is greater than the diameter of the limiting rod 8, and an arc-shaped protrusion 5 is fixedly provided on one side wall of the first guide rail 4.

[0032] As one possible implementation method, such as Figure 4 As shown, the width of the first guide rail 4 matches the diameter of the limiting rod 8, and the middle part of the first guide rail 4 protrudes to one side to form a protrusion 5.

[0033] When the limiting rod 8 contacts the upper or lower side of the protrusion 5, it needs to overcome the spring force and move along the width direction of the first guide rail 4 to bypass the obstruction of the protrusion 5 in order to continue to lower or raise. After the limiting rod 8 passes the protrusion 5, under the action of the spring force, the limiting rod 8 returns to its position corresponding to the protrusion 5 vertically.

[0034] A tube 12 is fixedly installed inside the limiting cylinder 3. The tube 12 is sleeved on the float 6 above the float ball 7. The inner diameter of the tube 12 is larger than the diameter of the float 6. Specifically, the distance that the float 6 moves radially inside the tube 12 is greater than or equal to the lateral movement distance of the limiting rod 8 when it passes around the protrusion 5.

[0035] The upper end of the float 6 extends out of the tube body 12 and is threadedly connected to an adjustment knob 13. Rotating the adjustment knob 13 adjusts the position of the float 7 on the float 6, that is, it adjusts the distance between the two ends of the whole formed by the float 7 and the plug 2 and the tube body 12 and the upper opening of the liquid outlet pipe 1. In turn, it adjusts the upper and lower limits of the liquid level rise and fall in the electrolytic cell when the float 7 drives the plug 2 to rise and fall.

[0036] The lower end of the limiting cylinder 3 is fixedly connected to a plurality of spaced fixing rods 14. The lower end of the fixing rod 14 is detachably connected to the outside of the liquid outlet pipe 1. Specifically, the lower end of the fixing rod 14 is bolted to the outside of the liquid outlet pipe 1.

[0037] It should be noted that the diameter of the circular structure formed by the plurality of fixing rods 14 is larger than the outer diameter of the annular protrusion 15.

[0038] In use, the limiting mechanism and the buoyancy mechanism are installed on the outlet pipe 1 inside the electrolytic cell by the fixing rod 14. At this time, the plug 2, together with the annular protrusion 15, seals the opening of the outlet pipe 1. The limiting rod 8 is located directly below the corresponding protrusion 5. When the adjustment knob 13 is turned, the float 7 cannot rotate due to the restriction of the elastic element 9. Therefore, the float 7 moves along the axial direction of the float rod 6. The distance between the float 7 and the plug 2 is adjusted, that is, the distance between the float 7 and the lower end of the pipe body 12 when the plug 2 seals the outlet pipe 1, so that the limit of the liquid level rise and fall is a suitable height. Then, electrolyte is added to the electrolytic cell.

[0039] As the liquid level in the electrolytic cell rises, the electrolyte submerges the plug 2 and the float 7. Under the action of buoyancy, the float 7, carrying the plug 2, rises until the limiting rod 8 contacts the lower side of the corresponding protrusion 5. The liquid level continues to rise, and the buoyancy on the float 7 and the plug 2 increases. When the buoyancy is sufficient to overcome the spring force, the limiting rod 8 moves laterally, bypassing the corresponding protrusion 5 and reaching above the protrusion 5. Subsequently, under the action of the spring force, the limiting rod 8 returns to its original position, corresponding vertically to the corresponding protrusion 5, and the outlet pipe 1 opens. However, due to the action of the plug 2, the liquid inflow into the electrolytic cell is still greater than the liquid outflow. As the plug 2 continues to rise, until the plug 2 opens the outlet pipe 1 to a greater extent or even completely leaves the outlet pipe 1, the liquid outflow into the electrolytic cell is greater than the liquid inflow (when the upper part of the float 7 tops the lower part of the pipe body 12). The liquid level in the electrolytic cell begins to drop.

[0040] As the liquid level in the electrolytic cell decreases, the buoyancy of the float 7 and the plug 2 decreases, causing them to descend. When the limiting rod 8 contacts the upper side of the corresponding protrusion 5, the float 7 and the plug stop descending. As the liquid level continues to decrease, the float 7 detaches from the electrolyte, and the plug 2 gradually floats out of the electrolyte surface. Since the plug 2 is open and hollow at the top, some electrolyte remains inside the plug 2 to increase its weight. When the buoyancy mechanism and the overall weight of the plug 2 overcome the buoyancy of the plug 2 (or reach the point where the plug 2 is no longer buoyant after detaching from the liquid surface) and the spring force, the limiting rod 8 moves laterally around the corresponding protrusion 5 and reaches below it. At this point, the plug 2's sealing effect on the outlet pipe 1 increases, causing the inflow of liquid into the electrolytic cell to exceed the outflow again, and the liquid level rises. This process is repeated continuously, causing the liquid level in the electrolytic cell to rise and fall within a certain range. The entire liquid level adjustment process does not require manual intervention and is automatically achieved by the buoyancy of the electrolyte, the gravity of the buoyancy mechanism, and the spring force.

[0041] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
