Description

Technical Field

[0001] The invention relates to the technical field of metallurgy and chemical engineering, and in particular to a continuous coarse indium replacement device. Background Art

[0002] Indium has been widely used in high-tech fields such as computers, energy, electronics, communications, optoelectronics, medicine and health, national defense and military, aerospace, nuclear industry and modern information industry. At present, it is mainly recovered from zinc smelting, and a small amount is also recovered from copper, lead and tin smelting. The extraction raw materials are mainly smelting by-products, such as hydrometallurgical / pyrometallurgical zinc smelting slag, crude lead refining slag, production wastewater, copper, lead, zinc, tin and steel smelting indium dust. Depending on the source of indium, its separation and recovery methods are also different. At present, the most widely used is the extraction replacement method, and its principle process is divided into acid leaching, extraction and enrichment of indium, replacement, casting and crude indium. In the production practice, the indium chloride solution or indium sulfate solution obtained by extraction and enrichment is usually placed in a replacement tank with an aluminum plate hanging on it until the sponge-like crude indium is taken out from the replacement tank after the replacement is completed.

[0003] At present, in the process of crude indium replacement extraction, a large amount of heat is first generated, which increases the temperature in the reaction container. If the temperature is too high, it will be difficult to condense and extract the crude indium. At the same time, during the extraction process, the indium chloride solution or the indium sulfate solution is placed in the replacement tank with the aluminum plate hanging on it, and the reaction continuity is poor. The indium in the solution cannot completely contact and react with the aluminum plate, which will cause residual indium ions in the solution. If the solution is placed in the reaction tank of the aluminum plate for a long time for a thorough reaction, the extraction efficiency will be greatly reduced. The traditional replacement extraction method has a slow efficiency and cannot replace the indium ions in the solution at a high proportion. In addition, the aluminum plate is always in the solution, and its consumption will increase, which will also lead to the problem of excessive consumption of the aluminum plate. Therefore, a continuous crude indium replacement device is proposed to solve the above-mentioned problems. Summary of the invention

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 7A continuous crude indium replacement device comprises a reaction box 1; a solution box 2 for storing an indium chloride solution or an indium sulfate solution obtained by extraction and enrichment; and a swinging continuous mechanism 4.

[0022] In this embodiment, the swing continuous mechanism 4 includes a drainage device for draining the solution inside the solution box 2 to the inside of the reaction box 1; a reaction device for controlling the indium chloride solution or the indium sulfate solution to perform a swing-type continuous replacement reaction; a driving device for driving the reaction device to perform a swing-type operation; and a temperature-controlled gas outlet device for automatically controlling the flow and discharging the high-temperature airflow generated by the replacement reaction.

[0023] Furthermore, the driving device includes a driving motor 401, the output end of the driving motor 401 is fixedly connected to a driving gear 402, one side of the driving gear 402 is fixedly connected to an axle pin 403, the surface of the axle pin 403 is slidably connected to a swing fork 404, the swing fork 404 is fixedly connected to a swing shaft 406, the swing shaft 406 is rotatably connected to the reaction box 1, the driving motor 401 is fixedly installed on the reaction box 1, and the swing shaft 406 is connected to the reaction device. The rotation of the driving motor 401 will drive the rotation of the driving gear 402, and will drive the rotation of the axle pin 403, and the axle pin 403 is in the groove inside the swing fork 404. With the rotation of the axle pin 403, the swing fork 404 will be driven to rotate in a circular swing, providing swing power for the subsequent reaction device, because during the swinging process, the aluminum plate 408 is not immersed in the solution, but interspersed and contacted in the solution, at this time, the consumption of the aluminum plate 408 will be low, avoiding the situation where the aluminum plate 408 is excessively consumed in the traditional immersion replacement.

[0024] Furthermore, the reaction device includes a plurality of plug plates 407, and an aluminum plate 408 is plugged into each plug plate 407, and the plurality of aluminum plates 408 are linearly staggeredly distributed. A bottom bracket 6 is fixedly installed at the bottom of the reaction box 1, and the solution box 2 and the reaction box 1 are inclined with the bottom bracket 6. A liquid outlet 405 is provided at the bottom of the reaction box 1, and the reaction box 1 is connected to the drainage device. When the solution just starts to enter the interior of the reaction box 1, it will be blocked by the first aluminum plate 408 and confined to the leftmost area. As the swing fork 404 swings, the swing shaft 406 will be driven to swing synchronously, and the swing shaft 406 will drive multiple plug plates 407 and aluminum plates 408 connected to its surface to swing. The aluminum plate 408 will contact with the solution, gradually break away from the first aluminum plate 408, and enter the side space of the second aluminum plate 408. When the first aluminum plate 408 rotates to the left extreme position and the right extreme position, along with the aluminum plates 408 distributed in a staggered array, the second aluminum plate 408 will block the flowing solution and contact it at the same time, thereby performing a contact replacement reaction, gradually replacing crude indium, and forming flocculent crude indium between each aluminum plate 408. In this way, the solution will sequentially intersperse and continuously contact multiple staggered aluminum plates 408, thereby forming a replacement reaction.

[0025] In addition, the drainage device includes a swing frame 420, which is fixedly connected to the swing fork 404. A cavity is provided in the swing frame 420. A filter plate 422 is fixedly installed on the swing frame 420. Filter holes are provided on both sides of the upper surface of the filter plate 422. A drainage tube 419 is slidably connected to the filter plate 422, and one end of the drainage tube 419 is connected to the solution tank 2. The swing fork 404 will drive the swing frame 420 to swing synchronously, and the swing frame 420 will drive the upper filter plate 422 to slide on the bottom of the drainage tube 419 during its rotation. After sliding to the left and right extreme positions, the solution inside the solution box 2 will follow the drainage tube 419 and then enter the inside of the swing frame 420 through the filter holes, and then flow from the inside of the two guide tubes 423 into the inside of the reaction box 1. Therefore, every time the swing frame 420 swings, it will drive the solution temporarily accumulated in the drainage tube 419 to flow to the inside of the two guide tubes 423 respectively, and flow out from the two holes. The filter holes can filter out many impurities, making the solution entering the reaction box 1 purer.

[0026] In addition, a partition 421 is fixedly installed inside the swing frame 420, and a guide pipe 423 is connected to both sides of the swing frame 420. One end of the guide pipe 423 is connected to the reaction box 1, and a retractable bellows is provided on the guide pipe 423. Because the entire swing frame 420 is in a state of swinging left and right, and at this time, in order to prevent the guide pipe 423 from being in a swinging state all the time, a retractable bellows is provided. Therefore, when the swing frame 420 swings, the retractable bellows will be squeezed and contracted, so as to achieve the contraction and giving way during the swing, and at the same time, it will not have too much impact on the flow of the entire solution, and the inner wall of the bellows needs to be coated with anti-corrosion paint to prevent the solution from corroding it when it flows through the bellows.

[0027] It is worth noting that the temperature-controlled gas outlet device includes a frame 3, on which an air outlet pipe 426 is installed, and a pressure plate 427 is slidably connected inside the air outlet pipe 426, one end of which is connected to a boost plate 424, and the surface of the boost plate 424 is slidably connected to the frame 3, a plate body is fixedly installed on the frame 3, and a pressure cavity is formed between the boost plate 424 and the plate body, and a plurality of heat conducting plates 425 are inserted and connected on the plate body, and the bottom of the heat conducting plates 425 is located in the cavity of the reaction box 1, and an air outlet 428 is provided on one side of the air outlet pipe 426, and an open groove 429 is provided inside the reaction box 1, and the internal reaction gas of the reaction box 1 enters the air outlet pipe 426 from the position of the open groove 429 and is discharged from the air outlet 428. A slide bar 417 is slidably connected to the solution box 2, and the bottom of the slide bar 417 is connected to the boost plate 424, and a compression spring 430 is sleeved on the surface of the slide bar 417. During the replacement reaction, the high temperature generated inside will enter the position of the air outlet pipe 426 from the position of the opening groove 429, and then be discharged from the position of the air outlet 428 to achieve exhaust. If the temperature inside the reaction box 1 continues to rise, the high temperature will be transmitted to the internal sealed cavity above the plate body through the heat conductive sheet 425. As the temperature rises, the air pressure in the internal cavity increases, thereby slowly lifting the booster plate 424. When the booster plate 424 gradually rises, it will drive multiple pressure plates 427 to rise, and then gradually enlarge the air outlet 428, thereby achieving large-volume exhaust, realizing rapid cooling of the inside of the reaction box 1, and maintaining the temperature balance inside the reaction box 1.

[0028] It is worth noting that the surface of the slide bar 417 is located inside the solution box 2 and is fixedly connected to a baffle 418 through a connector, and the baffle 418 is located above the drainage tube 419. When the temperature rises, it means that the internal solution reaction consumption is too large. At this time, as the booster plate 424 is lifted, the slide bar 417 is also lifted, and then the baffle 418 is lifted. At this time, the solution inside the solution box 2 will flow into the drainage tube 419 at a large flow rate, and the larger the amount of accumulation, the more solution will flow through the reaction box 1 each time as the swinging process occurs, thereby automatically increasing the amount of solution put in each time, which is convenient for the rapid extraction of crude indium.

[0029] In addition, the protection door 5 includes a protection frame 501, which is fixed to the side of the reaction box 1. Two sliding doors 502 are slidably connected inside the protection frame 501. When the aluminum plate 408 inside the reaction box 1 is gradually consumed, the operator can relatively open the two sliding doors 502 to open the entire reaction box 1, and re-insert a new aluminum plate 408 into the interior of the plug plate 407, so as to facilitate the replacement of the internal aluminum plate 408.

[0030] In addition, a self-extraction device is also included, which includes an intermediate gear 7, which is rotatably connected to the reaction box 1, and a transmission gear 410 is meshed on the surface of the intermediate gear 7, and a rotating shaft 412 is fixedly connected to the transmission gear 410, and a collecting box 411 is rotatably connected to the surface of the rotating shaft 412, and a feeding port 414 is provided on the surface of the collecting box 411, and a spiral blade 413 is fixedly connected to the surface of the rotating shaft 412, and a discharge port 415 is provided at the bottom of the collecting box 411, and a collecting rack 416 is connected to the bottom of the collecting box 411, and an extraction rack 409 is arranged between every two plug plates 407, and the extraction rack 409 is fixed to the swing shaft 406 through a connecting rod. During the swinging process of the swing shaft 406, the extraction frame 409 will also be driven to swing, and then the crude indium in the flocculent material will be swung by the extraction frame 409 during the swinging process, and rotated to the position of the feed port 414, so that it enters the interior of the collection box 411. After that, during the rotation process of the driving gear 402, the gear meshing will drive the rotation of the transmission gear 410, and the transmission gear 410 will drive the rotation of the rotating shaft 412, and then drive the spiral blade 413 to rotate. With the rotation of the spiral blade 413, the flocculent crude indium in the collection box 411 will be driven to be transported horizontally, and discharged from the position of the discharge port 415 to the interior of the collection frame 416, so as to realize the automatic internal extraction of the crude indium, without the need to shut down the equipment, thereby realizing the continuous replacement extraction of the crude indium, and indirectly improving the overall efficiency of the crude indium extraction.

[0031] Working principle: first, the operator places the indium chloride solution or indium sulfate solution obtained by extraction and enrichment in the solution box 2, and a delivery pipeline is set on the solution box 2. Through the injection of the pipeline, it enters the interior of the solution box 2, and the solution box 2 is fixed on the frame 3, and the frame 3 is connected to the reaction box 1. Finally, the bottom bracket 6 contacts and bears the ground. Then, as the solution box 2 is tilted, the solution inside will follow gravity and flow to the right. At this time, controlling the rotation of the driving motor 401 will drive the rotation of the driving gear 402, and will drive the rotation of the shaft pin 403. The shaft pin 403 is in the groove inside the swing fork 404. As the shaft pin 403 rotates, the swing fork 404 will be driven to rotate in a circular swing, and the swing fork 404 will drive the swing frame 420 to swing synchronously. During the rotation of the swing frame 420, the filter plate 422 above will be driven to slide on the bottom of the drainage pipe 419. After sliding to the left and right extreme positions, the solution inside the solution box 2 will follow the drainage pipe 419 and then enter the inside of the swing frame 420 through the filter holes, and then flow from the inside of the two guide pipes 423 into the inside of the reaction box 1. Therefore, every time the swing frame 420 swings, it will drive the solution temporarily accumulated in the drainage pipe 419 to flow to the inside of the two guide pipes 423 respectively, and flow out of the two holes. The filter holes can filter out many parts of some impurities, making the solution entering the reaction box 1 purer.When the solution just starts to enter the reaction box 1, it will be blocked by the first aluminum plate 408 and restricted to the leftmost area. As the swing fork 404 swings, it will synchronously drive the swing shaft 406 to swing, and the swing shaft 406 will drive the multiple plug plates 407 and aluminum plates 408 connected to its surface to swing. The swing is divided into three amplitudes in total. The first amplitude is the left extreme position, the second is the right extreme position, and the third is the middle position. The left extreme position and the right extreme position mean the left and right extreme positions of the rotation of the swing shaft 406, and the middle position is when the swing shaft 406 is in the middle position, so when the swing shaft 406 swings When the reaction box 1 is swung, the solution is blocked by the first aluminum plate 408, which will prevent it from flowing downward. Because the reaction box 1 is in an inclined state, the solution will have a force to slide downward. As the swinging process proceeds, the aluminum plate 408 will contact with the solution, gradually break away from the first aluminum plate 408, and enter the side space of the second aluminum plate 408. When the first aluminum plate 408 rotates to the left limit position and the right limit position, along with the aluminum plates 408 distributed in a staggered array, the second aluminum plate 408 will block the flowing solution and achieve contact at the same time, thereby performing a contact replacement reaction and gradually replacing the crude indium. The solution will be interlaced and continuously contacted with the multiple staggered aluminum plates 408 in sequence to form flocculent indium. In this way, the solution will be continuously contacted with the multiple staggered aluminum plates 408 to form a replacement reaction, realize a continuous replacement reaction, and finally precipitate the indium ions in the solution to achieve extraction. Finally, the solution will be discharged from the position of the liquid outlet 405. At this time, the indium ions in the solution have basically been precipitated. Because of the continuous contact reaction of the aluminum plates 408, the separation and replacement effect of the contact has reached the extreme, so the replacement reaction effect is very thorough, and there is basically no residual indium ions. The produced flocculent coarse indium will be precipitated during the swing of the swing shaft 406. During the process, the extraction rack 409 will be driven to swing, and then the extraction rack 409 will swing the crude indium of the flocs to the position of the feed port 414, so that it enters the interior of the collection box 411. After that, during the rotation of the driving gear 402, the gear meshing will drive the transmission gear 410 to rotate, and the transmission gear 410 will drive the rotation of the rotating shaft 412, and then drive the spiral blade 413 to rotate. With the rotation of the spiral blade 413, the flocculent crude indium inside the collection box 411 will be transported horizontally and discharged from the position of the discharge port 415 to the interior of the collection rack 416. Therefore, the entire device realizes intermittent delivery of the solution, and also realizes the swinging contact reaction of the solution and the aluminum plate 408, and realizes the automatic internal extraction of the crude indium, without the need to stop the equipment, thereby realizing the continuous replacement extraction of the crude indium, and improving the overall efficiency of the crude indium extraction from the side.During the replacement reaction, the high temperature generated inside will enter the position of the air outlet pipe 426 from the position of the opening groove 429, and then be discharged from the position of the air outlet 428 to achieve exhaust. If the temperature inside the reaction box 1 continues to rise, the high temperature will be transmitted to the internal sealed cavity above the plate body through the heat conductive sheet 425. As the temperature rises, the air pressure in the internal cavity increases, thereby slowly lifting the booster plate 424. When the booster plate 424 gradually rises, it will drive multiple pressure plates 427 to rise, and then gradually enlarge the air outlet 428, thereby achieving large-volume exhaust, achieving rapid cooling of the inside of the reaction box 1, and maintaining the temperature balance inside the reaction box 1. Therefore, the overall process of automatic temperature control and exhaust is also realized without the need for manual intervention by the operator, which improves the degree of automation of the equipment and facilitates the operator's simple operation.
