Description

Technical Field

[0001] This application relates to the technical field of metal separation in production lines, and in particular to a germanium selective adsorption device based on an indium production line. Background Technology

[0002] In indium production lines, germanium often exists as a by-product. However, due to the similar chemical properties of germanium and indium, traditional precipitation or extraction methods easily lead to co-precipitation or emulsification, resulting in low separation efficiency and high energy consumption. This paper proposes a technique for the efficient separation and enrichment of germanium from complex solutions containing indium and germanium using specific adsorbents. This method not only avoids the problems of lengthy steps, high reagent consumption, and low germanium recovery rates in traditional precipitation or extraction processes, but also significantly reduces production costs and environmental pollution. It is particularly suitable for treating low-grade germanium and high-impurity indium production line by-products or waste liquids, and is of great significance for the resource recovery of rare and dispersed germanium and the purification of indium products.

[0003] Currently, there are no germanium adsorption devices specifically designed for indium production lines. However, the electrolytic zinc production process requires the separation and recovery of rare metals such as indium and germanium, as exemplified by the waste liquid filtration device for the indium-germanium recovery process in electrolytic zinc production (publication number CN215161623U). The aforementioned prior art provides a waste liquid filtration device for the indium-germanium recovery process in electrolytic zinc production, comprising a tank with a wastewater outlet on the upper left side. A main toothed disc fixedly connected to the bottom of a stirring rod meshes and rotates with a driven toothed disc movably connected to the middle of a collection box. During this rotation, a support shaft fixedly connected to the bottom of the driven toothed disc rotates inside the collection box, causing a brush plate at the bottom of the support shaft to clean the surface of the ultrafiltration membrane, improving the filtration effect. Furthermore, when the cover is rotated and removed, a spring ring ejects the ultrafiltration membrane inside the collection box, facilitating replacement and cleaning.

[0004] However, the existing technologies mentioned above still have some drawbacks when it comes to the selective adsorption of germanium: 1. The existing technologies use components such as collection boxes, brush plates and main toothed discs to clean the surface of the ultrafiltration membrane by the brush plates at the bottom of the support shaft, thereby improving the filtration effect. However, this method has a slow filtration speed and low efficiency in the recovery of indium and germanium, which is still a drawback.

[0005] 2. The above-mentioned prior art uses components such as a collection box, a pneumatic telescopic rod, and a clamping plate in combination. After the sewage inside the tank is filtered, the pneumatic telescopic rod drives the clamping plate to move down at the bottom of the tank, so that the collection box can be removed from the inside of the limiting sleeve. This makes it convenient to take out the heavy metals inside the collection box for centralized treatment. However, it cannot selectively treat germanium, and there are still technical defects.

[0006] Based on this, and given the above viewpoints, there is still room for improvement in the existing technology for the selective adsorption of germanium. Summary of the Invention

[0035] The following is in conjunction with the appendix Figures 1 to 11 This application will be described in further detail.

[0036] This application discloses a germanium selective adsorption device based on an indium production line, which can significantly improve the adsorption of germanium by realizing the swinging of the adsorption frame through a unique mechanical structure.

[0037] refer to Figure 1 and Figure 2A germanium selective adsorption device based on an indium production line includes a housing 11, which is stacked vertically to achieve multi-stage adsorption of germanium. A support leg 12 is provided on the lowermost housing 11. A water inlet pipe 13 is provided at the upper end of the housing 11, and a water outlet pipe 14 is provided at the lower end of the housing 11. The water inlet pipes 13 and outlet pipes 14 of adjacent housings 11 are interconnected. A germanium-containing solution enters the housing 11 through the water inlet pipe 13, is treated by germanium adsorption, and is discharged through the water outlet pipe 14, then enters the next housing 11 for further treatment. After multiple adsorption treatments, the germanium is removed. A side opening is provided on the housing 11. The operating port 15 is equipped with a barrier door 16 to facilitate the replacement of the device for processing germanium inside the housing 11. A buffer frame 17 is provided at the upper end of the housing 11 for temporarily storing the germanium-containing solution to be processed. A collection frame 18 is provided at the lower end of the housing 11, and the lower end of the collection frame 18 is connected to the water outlet pipe 14 for collecting the solution after germanium is adsorbed. A partition plate 19 is provided in the middle of the collection frame 18, and a recovery frame 110 is slidably provided on the collection frame 18 and is located on one side of the partition plate 19. After separating germanium from the solution, germanium is eluted and the germanium-enriched solution is recovered.

[0038] When processing germanium-containing solutions, the germanium-containing solutions enter the housing 11 through the inlet pipe 13. After the germanium is adsorbed by the multi-stage device inside the housing 11, the solution is discharged from the outlet pipe 14. When recovering germanium, the germanium is eluted with a desorption solution to obtain a concentrated solution, which is collected by the recovery frame 110.

[0039] refer to Figure 3 This is a schematic diagram of the structure of the adsorption component 2 of the present invention. In order to adsorb germanium in the solution, an adsorption component 2 is provided between the buffer frame 17 and the collection frame 18. The adsorption component 2 includes several mounting shafts 21 disposed on the inner side walls of the housing 11. A swing frame 22 is rotatably disposed on the same set of mounting shafts 21. When adsorbing germanium, the swing frame 22 swings back and forth periodically. A mounting frame 23 is mounted on the swing frame 22. Two guide frames 24 are respectively disposed on the lower two sides of the mounting frame 23, and the two guide frames 24 are respectively located on both sides of the partition plate 19. An adsorption frame 25 is slidably disposed in the mounting frame 23. A liquid outlet 26 is opened on both sides of the bottom of the adsorption frame 25. Several adsorption plates 27 are staggered inside the adsorption frame 25. When the swing frame 22 swings, the solution and the surface of the adsorbent particles undergo relative shearing motion, which reduces the liquid film resistance and promotes the diffusion of germanium ions to the surface of the adsorbent. Indium ions have a large hydration radius and high charge density, making it difficult for them to approach the adsorbent, thereby achieving selective adsorption. The solution after adsorption treatment is discharged through the liquid outlet 26.

[0040] After the germanium-containing solution enters the adsorption frame 25 through the buffer frame 17, the swing frame 22 swings, and the solution on the adsorption frame 25 flows in a meandering manner within the adsorption frame 25, increasing the contact time with the adsorption plate 27 so as to adsorb the germanium in the solution. Finally, after the adsorption treatment, the solution is discharged through the outlet 26.

[0041] refer to Figure 4 This is a schematic diagram of the structure of the swing assembly 3 of the present invention. In order to swing the swing frame 22, the lower end of the buffer frame 17 is provided with the swing assembly 3. The swing assembly 3 includes a mounting frame 31 provided in the housing 11. A rotating shaft 32 is rotatably mounted on the mounting frame 31. A rotating disk 33 is mounted on the side of the rotating shaft 32 facing the swing frame 22. A telescopic rod 34 is provided at the eccentric part of the rotating disk 33. A sliding block 35 is slidably provided on the side end of the swing frame 22. A connecting block 36 is rotatably provided on one end of the telescopic rod 34. The sliding block 35 and the connecting block 36 are hinged together. When the rotating shaft 32 rotates, the rotating disk 33 rotates accordingly. Under the drive of the telescopic rod 34, the sliding block 35 slides back and forth, thereby driving one end of the swing frame 22 to rise and fall, so that the swing frame 22 swings.

[0042] refer to Figure 5 This is a schematic diagram of the structure of the drive component 4 of the present invention. In order to drive the rotating disk 33 to rotate, the lower end of the buffer frame 17 is provided with the drive component 4. The drive component 4 includes a connecting pipe 41 provided at the lower end of the buffer frame 17. A rotating impeller 42 is installed in the connecting pipe 41. The impeller shaft 43 on the rotating impeller 42 extends downward to the side end of the swing frame 22. The lower end of the impeller shaft 43 and the side of the rotating shaft 32 away from the rotating disk 33 are respectively provided with bevel gears 44 that mesh with each other. When the solution flows into the connecting pipe 41 from the lower end of the buffer frame 17, the solution falls and impacts the blades, causing them to rotate continuously. When the impeller shaft 43 rotates, under the meshing of the bevel gears 44, it drives the rotating shaft 32 and the rotating disk 33 to rotate.

[0043] refer to Figure 6 This is a schematic diagram of the flow guiding component 5 of the present invention. In order to guide the solution to the middle of the adsorption frame 25, the flow guiding component 5 is provided on the connecting pipe 41. The flow guiding component 5 includes a diverter pipe 51 provided on the side end of the connecting pipe 41. A connecting plate 52 is provided on the upper end of the mounting frame 23. An outlet pipe 53 is installed on the connecting plate 52. The outlet pipe 53 and the diverter pipe 51 are connected by a connecting hose 54. When the adsorption frame 25 swings, the solution can smoothly enter the outlet pipe 53 from the connecting pipe 41 under the connection of the connecting hose 54. The solution flowing out of the connecting pipe 41 flows through the diverter pipe 51, the connecting hose 54 and the outlet pipe 53 to the middle of the adsorption frame 25 in one go.

[0044] refer to Figure 7 This is a schematic diagram of the structure of the energy storage and drainage component 6 of the present invention. In order to ensure the flow rate of the solution through the connecting pipe 41 so that the rotating impeller 42 can rotate, the energy storage and drainage component 6 is provided in the buffer frame 17. The energy storage and drainage component 6 includes a support frame 61 provided in the buffer frame 17. The support frame 61 has an outlet 62 on its side. A sliding rod 63 is slidably provided on the support frame 61. A blocking plug 64 is provided at the lower end of the sliding rod 63. A floating airbag 66 is installed at the upper end of the sliding rod 63 through a connecting arm 65.

[0045] When the liquid level in the buffer frame 17 is low, the blocking plug 64 blocks the connecting pipe 41 to prevent the solution in the buffer frame 17 from flowing into the connecting pipe 41. As the liquid level in the buffer frame 17 gradually rises, the sliding rod 63 slides upward under the action of the floating airbag 66 until the blocking plug 64 is raised above the outlet 62. Since the liquid level is high at this time, the pressure on the bottom of the buffer frame 17 is greater to ensure the flow rate of the solution through the connecting pipe 41. At the same time, the flowing solution pushes the blocking plug 64 up to ensure that the solution can continuously pass through the connecting pipe 41 until the solution in the buffer frame 17 is completely discharged. Under the action of gravity, the blocking plug 64 flushes the blocking connecting pipe 41.

[0046] refer to Figure 8 This is a schematic diagram of the sliding adjustment component 7 of the present invention. After the adsorption plate 27 is saturated with germanium ions, in order to collect the enriched solution of germanium elution by the recovery frame 110, a sliding adjustment component 7 is provided on the mounting frame 23. The sliding adjustment component 7 includes sliding strips 71 slidably disposed on both sides of the mounting frame 23. The sliding strips 71 are provided with a connecting groove 72 corresponding to the liquid outlet 26. The connecting grooves 72 correspond one-to-one with the guide frame 24. When the connecting groove 72 is located directly above the guide frame 24, the liquid in the adsorption frame 25 can flow out from the guide frame 24. The two ends of the two sliding strips 71 are connected by connecting strips 73. The two connecting strips 73 are provided with a connecting rod 74 on the side facing the operation port 15. A sliding handle 75 is provided on the connecting rod 74.

[0047] When the adsorption plate 27 is saturated, the sliding bar 71 is slid by the sliding handle 75 to adjust the position of the connecting groove 72, so that the guide frame 24 above the recovery frame 110 is connected to the inside of the adsorption frame 25. The desorption liquid is used to elute the adsorption plate 27 to obtain a germanium-enriched solution. The enriched solution flows from the guide frame 24 into the recovery frame 110 and is collected. After collection, the sliding bar 71 is slid by the sliding handle 75 again, so that the guide frame 24 above the collection frame 18 is connected to the inside of the adsorption frame 25, and the solution can be selectively adsorbed for germanium again.

[0048] refer to Figure 9 The diagram shows the structure of the locking component 76 of the present invention. In order to prevent the sliding bar 71 from sliding arbitrarily, the connecting rod 74 and the side of the guide frame 24 are provided with the locking component 76. The locking component 76 includes locking blocks 761 symmetrically arranged on the side of the guide frame 24 facing the operation port 15. The connecting bar 73 is hinged to the locking bar 763 through the connecting bracket 762, which cooperates with the locking block 761. After the sliding bar 71 is slid, the locking bar 763 is rotated to make the locking block 761 lock the locking bar 763, thereby restricting the sliding of the sliding bar 71.

[0049] refer to Figure 10This is a schematic diagram of the structure of the fixing component 8 of the present invention. In order to fix the adsorption frame 25 to the mounting frame 23 and prevent the adsorption frame 25 from falling off when it swings, the fixing component 8 is provided on the sliding bar 71. The fixing component 8 includes a fixing bar 81 provided on one side of the two sliding bars 71 facing each other. The bottom of the adsorption frame 25 is provided with a fixing protrusion 82 that cooperates with the fixing bar 81. The fixing protrusion 82 cooperates with the fixing bar 81 to lock the position of the adsorption frame 25. A locking hole 83 is opened on the side end of the fixing protrusion 82. A locking post 84 is provided on each of the two connecting bars 73, and the locking post 84 passes through the locking hole 83 to lock the adsorption frame 25.

[0050] After the adsorption frame 25 is positioned and inserted into the mounting frame 23 by the fixing strip 81 and the fixing protrusion 82, during operation, the sliding strip 71 slides while the locking pin 84 engages in the locking hole 83, thus locking the adsorption frame 25. When it is necessary to remove the adsorption frame 25, the connecting rod 74 is slid to the middle of the mounting frame 23 by the sliding handle 75, so that the locking pins 84 on both sides of the connecting strip 73 disengage from the locking hole 83. At this time, the adsorption frame 25 can be removed to replace the adsorbent and achieve continuous production.

[0051] refer to Figure 11 This is a schematic diagram of the structure of the recovery rinsing assembly 9 of the present invention. After adsorption is completed, in order to rinse the adsorption plate 27 and collect the germanium-rich desorption liquid, the recovery rinsing assembly 9 is provided on the connecting plate 52. The recovery rinsing assembly 9 includes a storage tank 91 provided on the connecting plate 52 for storing the desorption liquid used to recover the adsorption plate 27. A connecting pipe 92 is provided on the storage tank 91. A flow divider 93 is provided at the lower end of the connecting plate 52, and both the connecting pipe 92 and the outflow pipe 53 extend into the flow divider 93 to divide the flow. The lower end of the cover 93 is provided with an outlet pipe 94. The recovery and rinsing assembly 9 also includes a connecting column 95 provided at the upper end of the connecting strip 73. A transmission rod 96 is provided at the side end of the connecting column 95, and the transmission rod 96 extends into the diversion cover 93. A blocking block 97 is provided at one end of the transmission rod 96. The blocking block 97 moves with the sliding strip 71 under the connection of the transmission rod 96. When adsorbing germanium ions, it blocks the connecting pipe 92. When recovering germanium ions on the adsorption plate 27, it blocks the outlet pipe 53.

[0052] During adsorption, the barrier block 97 is located at the lower end of the connecting pipe 41 to prevent the desorption liquid in the storage tank 91 from flowing out. At this time, the outflow pipe 53 is kept in a connected state so that the germanium-containing solution can enter the adsorption frame 25. After the sliding bar 71 moves, the guide frame 24 above the recovery frame 110 is opened. At the same time, the barrier block 97 is located at the lower end of the outflow pipe 53 to prevent the germanium-containing solution from entering the adsorption frame 25. Meanwhile, the desorption liquid in the storage tank 91 enters the adsorption frame 25 to rinse the adsorption plate 27 and collect the germanium-rich desorption liquid.

[0053] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
