Description

Technical Field

[0001] The present invention relates to the technical field of metal extraction from copper electroplating solutions, and specifically to a metal extraction, recovery and utilization device for copper electroplating solutions. Background Art

[0002] Metal extraction, recovery and utilization devices for copper electroplating solutions are usually used to extract copper and other valuable metals from copper-containing electroplating wastewater or solutions. They not only contribute to the recycling of resources but also reduce environmental pollution, meeting the requirements of green environmental protection.

[0003] The patent with the patent announcement number CN215404422U relates to a metal extraction, recovery and utilization device for copper electroplating solutions, including a base. Four corners of the lower end of the base are fixedly connected with anti-slip sleeves. The upper end of the base is fixedly connected with a recovery box. The middle and lower part of the right end of the recovery box is inserted and movably connected with an outlet plug. A rectifier is installed at the upper left part of the front end of the recovery box. The front part of the upper end of the recovery box is movably sleeved with a box cover. The upper end of the recovery box is fixedly connected with a filter box. A filter component is movably sleeved in the filter box. The lower rear part of the right end of the filter box is inserted and fixedly connected with a delivery pipe. The lower end of the delivery pipe is inserted and fixedly connected with the upper end of the recovery box. For the precious metal extraction and recovery device described in this patent, by setting the filter component, the waste liquid is filtered through the filter screen on the fixed frame. The mesh holes of the filter screen filter out solid impurities and the like, while the waste liquid seeps into the filter box through the mesh holes of the filter screen, thereby realizing the purification and filtration of the waste liquid and improving the recovery purity of precious metals.

[0004] In the above patent, by setting the filter component, the waste liquid is filtered through the filter screen on the fixed frame. The mesh holes of the filter screen filter out solid impurities and the like. However, during the filtering process, there are many impurities in the waste liquid and it is impossible to filter it cleaner, which may affect the metal extraction and recovery efficiency. Therefore, a metal extraction, recovery and utilization device for copper electroplating solutions with recovery, filtration and decomposition is designed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a metal extraction, recovery and utilization device for copper electroplating solutions, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: A metal extraction and recycling device for copper electroplating solution, comprising a base, above which a recycling box is fixedly installed, above which a filtration box is fixedly installed, above which a motor one is fixedly installed, and a feed pipe is fixedly penetrated through the side of the filtration box. A motor two is fixedly installed on the side of the recycling box. Inside the filtration box, there is a filtration, recycling and decomposition device for filtering and recycling the copper electroplating solution. The filtration, recycling and decomposition device includes a medicine box fixedly installed on the side of the filtration box. A filter plate is slidably installed on the inner wall of the filtration box, and a mounting plate is fixedly installed on the inner wall of the filtration box. A T-shaped plate is fixedly installed above the filter plate. The output end of the motor one is fixedly installed with a rotating shaft one, and a stirring rod one is fixedly installed on the circumferential surface of the rotating shaft one. The output end of the motor two is fixedly installed with a rotating shaft two, and a stirring rod two is fixedly installed on the circumferential surface of the rotating shaft two. An electrolytic cell is fixedly installed inside the recycling box. When the filter plate moves downward, it will drive the T-shaped plate to move downward. When the T-shaped plate moves downward, it will release the blockage of the medicine outlet groove. When the medicine outlet groove is not blocked, the reducing agent in the medicine box will flow into the interior of the filtration box from the medicine outlet groove and merge with the copper electroplating solution.

[0007] According to the above technical solution, a first spring is provided between the upper part of the filter plate and the mounting plate. The side surface of the T-shaped plate is slidably connected to the inner wall of the filtration box. When the T-shaped plate moves downward, it will release the blockage of the medicine outlet groove.

[0008] According to the above technical solution, a medicine outlet groove is provided on the side surface of the filtration box, and the surface of the medicine outlet groove is slidably connected to the T-shaped plate. The reducing agent in the medicine box will flow into the interior of the filtration box from the medicine outlet groove and merge with the copper electroplating solution.

[0009] According to the above technical solution, a recycling device for extracting and recycling the metal of the electroplating solution is provided on the inner wall of the recycling box. The recycling device includes a scraper slidably installed on the surface of the electrolytic cell. An extrusion block is fixedly installed on the side surface of the scraper. A baffle is slidably installed on the side surface of the recycling box. A square plate is fixedly installed on the side surface of the baffle. A recycling frame is fixedly penetrated through the surface of the base. When the rotating shaft two rotates, it will drive the stirring rod two to rotate. The rotation of the stirring rod two will stir the copper electroplating solution, making the copper electroplating solution fully contact with the electrolytic cell in the electrolytic cell, and making the extraction of metal from the copper electroplating solution more sufficient.

[0010] According to the above technical solution, the electrolytic cell is slidably connected to the inner wall of the recycling box. The side surface of the extrusion block is provided with a first inclined surface. When the scraper moves towards the end away from the motor two, it will drive the extrusion block on the side surface to move towards the end away from the motor two.

[0011] According to the above technical solution, a second spring is provided between the side surface of the recycling box and the inner wall of the baffle. The scraper is slidably connected above the recycling box. When the scraper moves towards the end away from the second motor, the metal that has been extracted from the electrolytic cell will be scraped towards the end away from the second motor.

[0012] According to the above technical solution, a cleaning device for cleaning the waste electroplating solution is provided above the base. The cleaning device includes a garbage bin. The garbage bin fixedly penetrates the surface of the base. A cross plate is fixedly installed on the side surface of the baffle. A first fixing plate is fixedly installed on the side surface of the recycling box. A pressing plate is slidably installed inside the garbage bin. A second fixing plate is fixedly installed on the inner wall of the filter box. A knocking plate fixedly penetrates the surface of the second fixing plate. Under the action of the second spring, the baffle will return to its initial state, driving the cross plate out of the range of the pressing plate. The pressing plate will return to its initial state under the action of the third spring, and squeeze the dust and foreign matters inside the garbage bin, improving the recycling efficiency.

[0013] According to the above technical solution, the side surface of the cross plate is provided with a second inclined surface. A third spring is provided between the upper part of the pressing plate and the first fixing plate. When the pressing plate is squeezed by the scraper, it will drive the pressing plate to move upward.

[0014] The present invention provides a metal extraction and recycling device for copper electroplating solution. It has the following beneficial effects: (1) For the metal extraction and recycling device for copper electroplating solution, when the medicine outlet groove is unobstructed, the reducing agent in the medicine box will flow into the interior of the filter box from the medicine outlet groove and mix with the copper electroplating solution. This can improve the metal recycling efficiency while optimizing the effect of the entire extraction process, reducing resource waste, lowering costs, and contributing to environmental protection. It can reduce impurity interference. The first stirring rod rotates to fully mix the copper electroplating solution and the reducing agent, making the impurities inside it filtered more thoroughly, improving the working efficiency of subsequent metal extraction and recycling, ensuring that the medicine fully reacts with metal ions and impurities in the waste liquid, thereby improving the precipitation and separation efficiency, enhancing the metal recovery rate, and improving the filtering effect.

[0015] (2) For the metal extraction and recycling device for copper electroplating solution, when the second rotating shaft rotates, it will drive the second stirring rod to rotate. The second stirring rod rotates to stir the copper electroplating solution, making the copper electroplating solution fully contact with the electrolytic cell in the electrolytic cell, making the extraction of metal from the copper electroplating solution more complete, optimizing the metal recycling efficiency during the electrolysis process, contributing to improving the speed and uniformity of the electrolysis reaction, preventing metal ion precipitation, enhancing the stability of the electrolyte, increasing the mass transfer rate, and thus realizing a more efficient and stable copper metal extraction and recycling process.

[0016] (3)The metal extraction and recycling equipment for the copper electroplating solution scrapes the metal onto the inner wall of the recycling box through a scraper for recycling, improving the recycling efficiency. On the contrary, after the metal is recycled, when the scraper moves towards the end away from the recycling box, it will drive the extrusion block to move towards the end away from the recycling box, and extrude another baffle to release the closure of the recycling box, facilitating the cleaning of foreign matters on the surface of the electrolytic cell, enhancing the efficiency, quality and economy of the electroplating process, and at the same time, it can also extend the service life of the equipment and ensure the sustainability of the copper electroplating process.

[0017] (4)The metal extraction and recycling equipment for the copper electroplating solution returns to the initial state under the action of spring three through the pressing plate, and squeezes the dust and foreign matters inside the dustbin, improving the recycling efficiency, contributing to enhancing the efficiency of metal extraction and recycling in the copper electroplating solution, reducing environmental pollution and resource waste at the same time, optimizing the entire recycling process. The filter plate will return to the initial state under the action of spring one, the filter plate moves upward to contact the bottom of the knocking plate, and the knocking plate will knock and clean the filter plate to prevent the filter plate from being blocked, contributing to maintaining the filtering effect, increasing the metal recovery rate, extending the service life of the filter plate, and at the same time, it can also ensure the stable operation of the equipment and reduce the maintenance cost.

The filtration and recovery device includes a medicine tank 71, the medicine tank 71 is fixedly installed on the side of the filtration tank 3, a filter plate 72 is slidably installed on the inner wall of the filtration tank 3, a mounting plate 73 is fixedly installed on the inner wall of the filtration tank 3, a T-shaped plate 75 is fixedly installed above the filter plate 72, the output end of the motor 1 4 is fixedly installed with a rotating shaft 1 76, a stirring rod 1 77 is fixedly installed on the circumferential surface of the rotating shaft 1 76, the output end of the motor 2 6 is fixedly installed with a rotating shaft 2 81, a stirring rod 2 82 is fixedly installed on the circumferential surface of the rotating shaft 2 81, an electrolytic cell 83 is fixedly installed inside the recovery tank 2. When the filter plate 72 moves downward, it will drive the T-shaped plate 75 to move downward. When the T-shaped plate 75 moves downward, it will release the blockage of the medicine outlet groove 78. When the medicine outlet groove 78 is not blocked, the reducing agent in the medicine tank 71 will flow into the interior of the filtration tank 3 from the medicine outlet groove 78 and mix with the copper electroplating solution.

[0022] A first spring 74 is arranged between the upper part of the filter plate 72 and the mounting plate 73. The side surface of the T-shaped plate 75 is slidably connected to the inner wall of the filtration tank 3. When the T-shaped plate 75 moves downward, it will release the blockage of the medicine outlet groove 78.

[0023] A medicine outlet groove 78 is opened on the side of the filtration tank 3. The surface of the medicine outlet groove 78 is slidably connected to the T-shaped plate 75. The reducing agent in the medicine tank 71 will flow into the interior of the filtration tank 3 from the medicine outlet groove 78 and mix with the copper electroplating solution.

[0024] During the operation of this embodiment: When in use, the copper electroplating solution is manually pumped from the pump into the filtration tank 3. The copper electroplating solution will pass through the filter plate 72 inside the filtration tank 3 for filtration. The filter plate 72 is subjected to the impact force of the copper electroplating solution, and the filter plate 72 will move downward. While the filter plate 72 moves downward, it will drive the T-shaped plate 75 to move downward. When the T-shaped plate 75 moves downward, it will release the blockage of the medicine outlet groove 78. When the medicine outlet groove 78 is not blocked, the reducing agent in the medicine box 71 will flow into the interior of the filtration tank 3 from the medicine outlet groove 78 and mix with the copper electroplating solution.

Finally, the copper electroplating solution will be filtered clean under the action of the filter plate 72 and flow into the recovery tank 2 from the feed pipe 5. At the same time, start the second motor 6. The rotation of the output end of the second motor 6 drives the rotation of the second rotating shaft 81. When the second rotating shaft 81 rotates, it will drive the rotation of the second stirring rod 82. The rotation of the second stirring rod 82 will stir the copper electroplating solution, making the copper electroplating solution fully contact with the electrolytic cell 83 in the electrolytic cell 83, making the extraction of metal from the copper electroplating solution more complete, optimizing the metal recovery efficiency in the electrolysis process, contributing to improving the speed and uniformity of the electrolysis reaction, preventing metal ion precipitation, enhancing the stability of the electrolyte, increasing the mass transfer rate, and thus realizing a more efficient and stable copper metal extraction and recovery process.

[0025] Please refer to Figures 1-7 , on the basis of the above embodiment, in another embodiment of the present invention, a recovery device for extracting and recovering the metal of the electroplating solution is provided on the inner wall of the recovery tank 2. The recovery device includes a scraping plate 84. The scraping plate 84 is slidably installed on the surface of the electrolytic cell 83. An extrusion block 85 is fixedly installed on the side surface of the scraping plate 84. A baffle 86 is slidably installed on the side surface of the recovery tank 2. A square plate 87 is fixedly installed on the side surface of the baffle 86. A recovery frame 89 is fixedly penetrated through the surface of the base 1. When the second rotating shaft 81 rotates, it will drive the rotation of the second stirring rod 82. The rotation of the second stirring rod 82 will stir the copper electroplating solution, making the copper electroplating solution fully contact with the electrolytic cell 83 in the electrolytic cell 83, making the extraction of metal from the copper electroplating solution more complete.

[0026] The electrolytic cell 83 is slidably connected to the inner wall of the recovery box 2. The side surface of the extrusion block 85 is provided with a first inclined surface. When the scraping plate 84 moves away from the second motor 6, it will drive the extrusion block 85 on the side to move away from the second motor 6.

[0027] A second spring 88 is provided between the side surface of the recovery box 2 and the inner wall of the baffle 86. The scraping plate 84 is slidably connected above the recovery box 2. When the scraping plate 84 moves away from the second motor 6, it will scrape the metal that has been extracted on the electrolytic cell 83 away from the second motor 6.

[0028] Above the base 1, a cleaning device for cleaning the waste electroplating solution is provided. The cleaning device includes a garbage bin 91. The garbage bin 91 is fixedly penetrated through the surface of the base 1. A cross plate 92 is fixedly installed on the side surface of the baffle 86. A first fixing plate 93 is fixedly installed on the side surface of the recovery box 2. A pressing plate 94 is slidably installed inside the garbage bin 91. A second fixing plate 96 is fixedly installed on the inner wall of the filter box 3. A knocking plate 97 is fixedly penetrated through the surface of the second fixing plate 96. Under the action of the second spring 88, the baffle 86 will return to the initial state, driving the cross plate 92 out of the range of the pressing plate 94. The pressing plate 94 will return to the initial state under the action of the third spring 95, and squeeze the dust and foreign objects inside the garbage bin 91, improving the recovery efficiency.

[0029] The side surface of the cross plate 92 is provided with a second inclined surface. A third spring 95 is provided between the upper part of the pressing plate 94 and the first fixing plate 93. When the pressing plate 94 is squeezed by the scraping plate 84, it will drive the pressing plate 94 to move upward.

[0030] During the operation of this embodiment: Subsequently, when the copper electroplating solution extraction is completed, the operator manually moves the scraping plate 84 away from the second motor 6. When the scraping plate 84 moves away from the second motor 6, it will scrape the metal that has been extracted on the electrolytic cell 83 away from the second motor 6. At the same time, when the scraping plate 84 moves away from the second motor 6, it will drive the extrusion block 85 on the side to move away from the second motor 6. When the extrusion block 85 moves away from the second motor 6, it will release and squeeze the side surface of the square plate 87. When the square plate 87 is squeezed, it will drive the baffle 86 on the surface to open the entrance of the recovery box 2. Subsequently, the scraping plate 84 will scrape the metal to the inner wall of the recovery frame 89 for recovery, improving the recovery efficiency. On the contrary, after the metal is recovered, when the scraping plate 84 moves away from the recovery frame 89, it will drive the extrusion block 85 to move away from the recovery frame 89 and squeeze another baffle 86 to release the closure of the recovery box 2, facilitating the cleaning of foreign objects on the surface of the electrolytic cell 83, improving the efficiency, quality and economy of the electroplating process, and at the same time, it can also extend the service life of the equipment and ensure the sustainability of the copper electroplating process.

[0031] Meanwhile, when another baffle 86 moves towards the end away from the scraper 84, it will drive the cross plate 92 on the surface to move towards the end away from the scraper 84. When the cross plate 92 moves towards the end away from the scraper 84, it will contact and squeeze the side surface of the pressing plate 94. When the pressing plate 94 is squeezed by the scraper 84, it will drive the pressing plate 94 to move upward, facilitating the entry of dust and foreign objects into the interior of the dustbin 91. Subsequently, when the baffle 86 returns to its initial state under the action of the second spring 88, it will drive the cross plate 92 out of the range of the pressing plate 94. The pressing plate 94 will return to its initial state under the action of the third spring 95 and squeeze the dust and foreign objects inside the dustbin 91, improving the recycling efficiency, contributing to enhancing the efficiency of metal extraction and recovery in the copper electroplating solution, reducing environmental pollution and resource waste at the same time, and optimizing the entire recycling process. Meanwhile, after the filter plate 72 stops operating, the filter plate 72 will return to its initial state under the action of the first spring 74. The filter plate 72 moves upward to contact the bottom of the knocking plate 97, and the knocking plate 97 will knock and clean the filter plate 72 to prevent the filter plate 72 from being blocked, contributing to maintaining the filtering effect, increasing the metal recovery rate, prolonging the service life of the filter plate 72, and ensuring the stable operation of the equipment and reducing the maintenance cost at the same time.
