Description

Technical Field

[0001] This utility model belongs to the field of electrolytic copper technology, and more specifically, it relates to a bubble elimination device in the electrolytic copper electrolysis process. Background Technology

[0002] In the process of copper electrolysis, the generation of bubbles mainly originates from electrode reactions (such as oxygen evolution at the anode and hydrogen evolution at the cathode). The accumulation of bubbles can significantly affect current efficiency, energy consumption and product quality. Currently, the commonly used defoaming method is a combination of mechanical stirring and electrolyte circulation system, which can push the bubbles inside the electrolyte upward to the top of the electrolyte level, thereby reducing the impact on the copper electrolysis process.

[0003] Existing application number: CN202121596869.9, this utility model provides an electrolytic cell for electrolytic copper. The electrolytic cell is disposed on the top of an electrolytic tank. A fixed plate is fixedly installed on the rear side of the top of the electrolytic tank, and a movable plate is disposed on the front side of the top of the electrolytic tank. A connecting rod is disposed at the bottom of the movable plate, and an embedded rod is fixedly connected to one side of the connecting rod. The embedded rod has a limit hole inside. The movable groove is disposed on one side of the front of the electrolytic tank. The limiting device is disposed on one side of the front of the top of the electrolytic tank. This utility model provides an electrolytic cell for electrolytic copper, which uses a fixed plate and a movable plate to wrap and limit the conductive rods at both ends of the copper plate, so that the two ends of the conductive rods are not exposed and cannot move freely. This avoids the conductive rods from moving and touching conductive materials due to bumps and impacts, reduces the working danger of workers, and improves the safety of the electrolysis process.

[0004] Based on the above, although mechanical stirring and electrolyte circulation in the electrolytic cell can bring the bubbles to the liquid surface, the top area of ​​the electrode may still experience a decrease in local current density, uneven copper deposition, pinholes or nodules on the cathode surface due to its proximity to the bubble layer, thus affecting the quality of the cathode copper surface. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a bubble elimination device during the electrolytic copper electrolysis process. This device solves the problem that while mechanical stirring and electrolyte circulation in the electrolytic cell can bring bubbles to the liquid surface, the top area of ​​the electrode, being close to the bubble layer, may still experience a decrease in local current density, uneven copper deposition, pinholes or nodules on the cathode surface, thus affecting the quality of the cathode copper surface.

[0006] The purpose and effectiveness of this utility model's bubble elimination device during copper electrolysis are achieved through the following specific technical means:

[0007] A bubble elimination device for copper electrolysis includes an electrolytic cell, electrodes, a front baffle tank, a rear baffle tank, drive cylinders, a first connecting water pipe, a water circulation pump, a defoaming component, and a filtration and separation component. Multiple electrodes are disposed within the electrolytic cell. The front baffle tank is fixedly connected to the front of the electrolytic cell. The rear baffle tank is fixedly connected to the rear of the electrolytic cell. Two drive cylinders are disposed, with their bottoms fixedly connected to the left and right sides of the electrolytic cell, respectively. The front and rear ends of the first connecting water pipe are fixedly connected to the right sides of the front and rear baffle tanks, respectively. The water circulation pump is fixedly connected to the left side of the electrolytic cell. The defoaming component is disposed inside and in front of the electrolytic cell. The filtration and separation component is disposed in front of the electrolytic cell.

[0008] Furthermore, the defoaming component includes: a connecting ring and water-blocking blocks; the connecting ring is fixedly connected to the piston rod ends of the two drive cylinders, and the connecting ring is slidably connected to the electrolytic cell; multiple water-blocking blocks are provided, and the multiple water-blocking blocks are dispersedly and fixedly connected to the connecting ring.

[0009] Furthermore, the defoaming assembly also includes: a connecting pipe and a water storage tank; the top of the connecting pipe is fixedly connected to the bottom of the front water tank; the water storage tank is fixedly connected to the front of the electrolytic cell.

[0010] Furthermore, the defoaming component also includes: a defoaming pump and a second connecting water pipe; the defoaming pump is fixedly connected to the water storage tank; the left and right ends of the second connecting water pipe are respectively fixedly connected to the water storage tank and the water circulation pump.

[0011] Furthermore, the filtration and separation assembly includes: a filter plate and a lifting ring; the filter plate is inserted into the top of the connecting tube; and the lifting ring is fixedly connected to the filter plate.

[0012] Furthermore, the filtration and separation assembly also includes: a sealing block, a fixing column, and a squeezing plate; the sealing block is inserted into the bottom of the front water tank; the fixing column is fixedly connected to the bottom of the front water tank; and the right end of the squeezing plate is rotatably connected to the bottom of the fixing column.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, when bubbles accumulate at the top of the electrolytic cell, the drive cylinder is activated to move the baffle block downwards. The electrolyte containing bubbles at the top flows into the front baffle tank through the notch. Then, the electrolyte flows into the storage tank through the connecting pipe and settles into layers. After the defoaming pump is activated to disperse the upper layer of bubbles, the water circulation pump re-injects the purified electrolyte into the electrolytic cell for recycling, thereby quickly eliminating the bubbles on the top layer of the electrolyte.

[0015] Secondly, when the electrolyte flows into the water storage tank through the connecting pipe, the filter plate can intercept the copper slag in the electrolyte, ensuring the cleanliness of the electrolyte entering the water storage tank. After rotating the squeezing plate to release the limit, the sealing block can be moved downwards to be removed from the bottom of the front water tank, which is convenient for cleaning the deposited copper slag and the filter plate trappings, ensuring that the circulation system is free from impurities.

[0016] This invention uses a drive cylinder to move a water baffle block to control the flow of electrolyte. After the electrolyte containing air bubbles is introduced into the water tank and allowed to settle and separate, the air bubbles are broken by an antifoaming pump and then circulated back into the electrolytic cell. At the same time, a filter plate intercepts copper slag. Combined with a detachable sealing block design, this achieves efficient cleaning of copper slag, reduces defects on the top surface of the electrode, lowers the cost of manual cleaning, and enables green and efficient production.

[0025] Example 1:

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] This utility model provides a bubble elimination device during the electrolysis of copper, including an electrolytic cell 1, electrodes 101, a front baffle tank 2, a rear baffle tank 3, a drive cylinder 4, a first connecting water pipe 6, a water circulation pump 11, and a defoaming component; multiple electrodes 101 are provided, and the multiple electrodes 101 are distributed inside the electrolytic cell 1; the front baffle tank 2 is fixedly connected to the front of the electrolytic cell 1; the rear baffle tank 3 is fixedly connected to the rear of the electrolytic cell 1; two drive cylinders 4 are provided, and the bottoms of the two drive cylinders 4 are respectively fixedly connected to the left and right sides of the electrolytic cell 1; the front and rear ends of the first connecting water pipe 6 are respectively fixedly connected to the right sides of the front baffle tank 2 and the rear baffle tank 3; the water circulation pump 11 is fixedly connected to the left side of the electrolytic cell 1; the defoaming component is provided inside and in front of the electrolytic cell 1.

[0028] The defoaming component includes a connecting ring 5 and a water-blocking block 501. The connecting ring 5 is fixedly connected to the piston rod ends of the two drive cylinders 4, and the connecting ring 5 is slidably connected to the electrolytic cell 1. Multiple water-blocking blocks 501 are provided, and the multiple water-blocking blocks 501 are dispersedly and fixedly connected to the connecting ring 5.

[0029] The defoaming component also includes: a connecting pipe 7 and a water storage tank 8; the top of the connecting pipe 7 is fixedly connected to the bottom of the front water tank 2; the water storage tank 8 is fixedly connected to the front of the electrolytic cell 1.

[0030] The defoaming component also includes: a defoaming pump 9 and a second connecting water pipe 10; the defoaming pump 9 is fixedly connected to the water storage tank 8; the left and right ends of the second connecting water pipe 10 are fixedly connected to the water storage tank 8 and the water circulation pump 11, respectively.

[0031] The specific usage and function of this embodiment are as follows: During use, if many bubbles appear at the top of the electrolyte in the electrolytic cell 1, the two drive cylinders 4 are activated to move the connecting ring 5 and the water-blocking block 501 downwards. At this time, the electrolyte mixed with bubbles will flow quickly into the front water tank 2 and the rear water tank 3 through the gap after the water-blocking block 501 falls. After the water level drops to the point where no more electrolyte flows out, the two drive cylinders 4 are activated again, and the connecting ring 5 and the water-blocking block 501 move upwards back to their original positions. The electrolyte in the front water tank 2 will flow into the water storage tank 8 through the connecting pipe 7, and the electrolyte in the rear water tank 3 will flow into the front water tank 2 through the first connecting water pipe 6 and then into the water storage tank 8. After the electrolyte in the water storage tank 8 has been left to stand for a while, the bubbles will float on the upper surface. The defoaming pump 9 is activated to disperse these bubbles and complete the defoaming work. Finally, the water circulation pump 11 is activated to extract the defoamed electrolyte from the water storage tank 8 and circulate it back into the electrolytic cell 1.

[0032] Example 2:

[0033] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown, it also includes a filtration and separation component, which is located in front of the electrolytic cell 1.

[0036] The specific usage and function of this embodiment: When the electrolyte in the front baffle tank 2 flows into the storage tank 8 through the connecting pipe 7, the filter plate 12 can filter the copper slag in the electrolyte to prevent the copper slag from affecting the subsequent electrolyte circulation process. At the same time, pulling the lifting ring 1201 upward can pull out the filter plate 12 for easy rinsing. Rotating the squeezing plate 15, the squeezing plate 15 rotates around the fixed column 14 as the axis. After releasing the restriction on the sealing block 13, the sealing block 13 moves downward, which can remove it from the front baffle tank 2, making it easy to remove and clean the copper slag deposited at the bottom of the front baffle tank 2 and trapped by the filter plate 12.
