Description

Technical Field

[0001] This invention relates to the field of metal recycling technology, and in particular to a palladium ion recycling device. Background Technology

[0002] Currently, palladium, as an important precious metal, is widely used in chemical fields such as catalytic hydrogenation / hydrogenolysis and coupling reactions. The treatment of palladium-containing liquids mainly focuses on the recovery of high-concentration palladium ions, while the treatment technology for low-concentration palladium-containing liquids is still immature, with problems such as low recovery efficiency and high treatment costs.

[0003] In existing technologies, the treatment and recovery of palladium-containing liquids and palladium ions typically employ a multi-step process. First, the palladium-containing liquid is pretreated using physical filtration to remove suspended solids, particulate matter, and other insoluble impurities, ensuring the smooth progress of subsequent treatment processes. Second, palladium ions are recovered using a resin exchange device. Utilizing the principle of resin exchange, palladium ions are effectively enriched in the palladium-containing liquid through chemical adsorption.

[0004] Regarding the aforementioned technologies, as the resin exchange reaction proceeds, palladium ions accumulate on the resin surface and encapsulate the resin. At this point, the resin in the resin exchange device needs to be replaced. First, the resin exchange device needs to be disassembled, the resin removed from the resin exchange device, and new resin needs to be added to the resin exchange device. This process takes a lot of time and is inconvenient to operate. Therefore, there is an urgent need for a palladium ion recovery device to improve the convenience of resin replacement. Summary of the Invention

[0005] To improve the convenience of resin replacement, this application provides a palladium ion recovery device.

[0006] This application provides a palladium ion recovery device, which adopts the following technical solution:

[0007] A palladium ion recovery device includes a filtration device and a resin exchange device. The filtration device removes solid particles from a liquid containing palladium ions, and the resin exchange device adsorbs palladium ions from the filtered liquid. A first infusion pipe is connected between the filtration device and the resin exchange device, and a water pump is installed in the first infusion pipe. A feeding device is installed on the resin exchange device. An activated carbon adsorption device is installed on the side of the resin exchange device away from the filtration device. A second infusion pipe is connected between the resin exchange device and the activated carbon adsorption device. A remote monitoring device is installed on one side of the resin exchange device. The control equipment is used to control the switching on and off of the water pump. The resin exchange device includes an exchange box, several storage baskets, and several permeable plates. The exchange box has several openings on one side along the horizontal direction. The storage baskets and permeable plates are one-to-one and are all located inside the exchange box. The permeable plates are located below the storage baskets and are attached to the storage baskets. The lower end of the storage basket has an opening. The permeable plates are fixedly connected to the inside of the exchange box and are set horizontally. The storage baskets are slidably connected to the permeable plates along the horizontal direction. Several storage baskets are fixed with the same support plate on the side near the opening. The outside of the exchange box is provided with a movable part for moving the support plate.

[0008] By adopting the above technical solution, the filtration device removes solid particles from the palladium-containing liquid. The water pump transports the palladium-containing liquid from the filtration device to the resin exchange device through infusion pipe one. The palladium ions in the liquid are adsorbed by the resin in the collection basket. The liquid flows into infusion pipe two through the permeable plate. When the resin needs to be replaced, the moving part controls the moving plate to move the collection box away from the exchange box in the opening one. The resin falls out from the opening two, and the palladium-containing liquid flows into the activated carbon adsorption device from infusion pipe two. The activated carbon adsorption device further adsorbs the palladium ions. The remote monitoring device monitors the water pressure inside the device and adjusts the liquid flow rate and water pump switch in a timely manner. The feeding device replenishes the resin in the resin exchange device in a timely manner, improving the convenience of resin replacement.

[0009] Optionally, the moving parts include a motor, a gear, and a rack. The rack is fixedly connected to one side of the support plate along the longitudinal direction. The rack is horizontally set and slidably connected to the exchange box along its own length. The motor is fixedly connected to the outside of the exchange box. The gear is fixedly connected to the output shaft of the motor. The gear meshes with the rack. A recovery trough is fixedly provided at the lower end of the exchange box. The lower end of the exchange box is connected to the infusion pipe.

[0010] By adopting the above technical solution, when the resin needs to be replaced, the motor rotates, the gear rotates, and the rack slides, causing the collection basket to slide within the first opening and move away from the exchange box. The resin passes through the second opening and falls into the recycling tank, improving the convenience of resin removal.

[0011] Optionally, several baffles are fixedly installed horizontally on the side of the exchange box near the opening. The baffles are located between two adjacent storage baskets. Several support openings are opened horizontally on the support plate. Sliding plates are installed in the support openings. The sliding plates are slidably connected to the support plate along their own length. When the storage basket is located outside the exchange box, the sliding plate is located below the storage basket and fits against the storage basket. Several protrusions are fixedly installed on both sides of the bottom sliding plate along the longitudinal direction. The protrusions are made of elastic material. The support plate has grooves that communicate with the support openings. A moving device is provided on the outside of the exchange box. The moving device is used to drive the remaining sliding plates to move sequentially.

[0012] By adopting the above technical solution, the baffle is used to reduce the probability of resin splashing during recycling and addition. When the original resin is removed, the bottom sliding plate is pushed to block the opening of the bottom storage basket. The groove and the protrusion cooperate to fix the bottom sliding plate. As resin is continuously added, the moving device drives the remaining sliding plate to block the opening of the storage basket. Several sliding plates block the opening of the storage basket from bottom to top in sequence, which improves the convenience of storing resin in the storage basket.

[0013] Optionally, the moving device includes a motor five, a rack two, a gear two, two connecting shafts, and two connecting rods. The rack two is located on the side of the exchange box away from the rack one and is slidably connected to the exchange box along its own length. The motor five is fixedly connected to the side of the exchange box away from the motor one. The gear two is fixedly connected to the output shaft of the motor five and meshes with the rack two. The two connecting shafts are respectively fixedly connected to the two sides of the rack two along the vertical direction. The lower connecting shaft is located on the side of the rack two away from the support plate, and the upper connecting shaft is located in the middle of the rack two. The two connecting rods are respectively fixedly connected to the two upper sliding plates. The connecting rods are arranged horizontally, and the connecting shafts are located between the connecting rods and the rack two. An elastic element is provided between the connecting shafts and the connecting rods. The elastic element is fixedly connected to the connecting shafts and slidably connected to the connecting rods. A positioning opening is provided on the side of the connecting rod away from the support plate along the vertical direction.

[0014] By adopting the above technical solution, motor five drives gear two to rotate, gear two causes rack two to move laterally. At this time, the elastic element on the lower connecting shaft is located in the positioning port of the lower connecting rod. The movement of rack two drives the middle connecting rod to move, and the lower connecting rod drives the middle sliding plate to move. When the middle sliding plate completely blocks the passage two, rack two continues to move, and the lower elastic element separates from the positioning port. At this time, the elastic element on the upper connecting shaft is located in the positioning port of the upper connecting rod. The upper connecting rod drives the upper sliding plate to block the passage two, which improves the convenience of the sliding plate blocking the passage two.

[0015] Optionally, the feeding device includes a feeding hopper, an auger, a second motor, a third motor, a rotating shaft, and several stirring rods. The feeding hopper is fixedly connected to the side of the exchange box near the first opening. The auger is located inside the feeding hopper and is horizontally arranged. The auger is rotatably connected to the feeding hopper. The second motor is fixedly connected to the outside of the feeding hopper. The output shaft of the second motor passes through the feeding hopper and is fixedly connected to the auger. The third motor is fixedly connected to the outside of the feeding hopper and is arranged vertically. The third motor is located on the side of the auger away from the second motor. The output shaft of the third motor passes through the feeding hopper. The rotating shaft is fixedly connected to the output shaft of the third motor. Several stirring rods are fixedly connected to the lower end of the rotating shaft and are evenly arranged along the circumference of the rotating shaft. A material leveling device is provided inside the second opening to ensure that the resin in the collection basket is evenly distributed.

[0016] By adopting the above technical solution, the resin is located inside the feed hopper. Motor 2 drives the auger to rotate, and the auger transports the resin to the top of the stirring rod. Motor 3 drives the stirring rod to rotate through the rotating shaft. The stirring rod performs preliminary stirring on the resin so that the resin enters the collection basket evenly. The uniformizing component further distributes the resin in the collection basket, improving the uniformity of the resin in the collection basket.

[0017] Optionally, the material leveling component includes a leveling plate, a screen, a motor, and a lead screw. The leveling plate is located inside the second opening. The storage basket has a sliding opening along the horizontal direction, and a slider is installed inside the sliding opening. The slider is slidably connected to the storage basket along the vertical direction and is fixedly connected to the leveling plate. The leveling plate is slidably connected to the storage basket along the vertical direction. The motor is located inside the sliding opening and is fixedly connected to the storage basket. The lead screw is fixedly connected to the output shaft of the motor and passes through the slider and is threadedly connected to the slider. The leveling plate has a third opening along the vertical direction, and the screen is located inside the third opening. The pore size of the screen is much larger than the particle size of the resin. The leveling plate has several sliding grooves along the vertical direction that communicate with the third opening. A slider is installed inside the sliding groove and is fixedly connected to the screen. Both the slider and the screen are slidably connected to the leveling plate along the vertical direction. A spring is installed inside the sliding groove. The outside of the spring is coated with polypropylene material to reduce the corrosion of the spring by the palladium ion liquid. One end of the spring is fixedly connected to the slider, and the other end of the spring is fixedly connected to the leveling plate.

[0018] By adopting the above technical solution, when the resin falls into the storage basket, the resin contacts the screen and generates an impact force on the screen. The screen slides vertically within the three openings, and the screen drives the sliding block two to slide within the sliding groove. The sliding block two compresses the spring. When the impact force disappears, the spring resets, causing the screen to move upward. Through the reciprocating movement of the screen, the resin is evenly distributed in the storage basket. As the amount of resin increases, the motor four drives the lead screw to rotate, causing the slider one to rise at the sliding opening. The slider one drives the uniform plate to rise, further improving the uniformity of the resin in the storage basket.

[0019] Optionally, a shield is provided inside the sliding opening. The shield is set vertically and fixedly connected to the storage basket. The shield passes through the first slider and is slidably connected to the first slider vertically.

[0020] By adopting the above technical solution, when slider one moves, slider one moves along the length direction of the shielding plate. The shielding plate is used to shield the sliding port, which helps to reduce the probability of resin splashing from the sliding port during resin removal and addition, and improves the stability of resin removal and addition.

[0021] Optionally, the activated carbon adsorption device includes an adsorption box and several activated carbon adsorption plates. The adsorption box is set vertically, and the end of the infusion pipe away from the exchange box is connected to the upper end of the adsorption box. Several activated carbon adsorption plates are located inside the adsorption box and arranged vertically. The pore size of the activated carbon in the several activated carbon adsorption plates decreases from top to bottom. The adsorption box has a horizontally opened port four. A sliding component is provided between the activated carbon adsorption plates and the adsorption box. The sliding component is used to drive the activated carbon adsorption plates to move and to block the port four. A flow equalization plate is fixed inside the adsorption box. The flow equalization plate is set horizontally and located at the upper end of the adsorption box. A discharge pipe is connected to the lower end of the adsorption box.

[0022] By adopting the above technical solution, the infusion tube delivers palladium-containing liquid into the adsorption box, and the activated carbon adsorption plate adsorbs palladium ions in the liquid. When the activated carbon adsorption plate needs to be cleaned, the sliding part moves the activated carbon adsorption plate within the four-way opening, the flow equalization plate makes the palladium-containing liquid flow evenly into the adsorption box, and the discharge pipe is used to discharge the adsorbed liquid, which improves the convenience of cleaning the activated carbon adsorption plate and the adsorption efficiency of the activated carbon adsorption plate.

[0023] Optionally, the sliding component includes several connecting blocks and a second baffle. The second baffle is fixedly connected to the activated carbon adsorption plate. The connecting blocks are all fixedly connected to the inside of the adsorption box and are set perpendicular to the second baffle. The activated carbon adsorption plate is located between the connecting blocks and is slidably connected to the connecting blocks along the length of the connecting blocks. A handle is fixedly provided on the side of the second baffle away from the adsorption box. A locking component is provided between the second baffle and the adsorption box to fix the second baffle and the adsorption box.

[0024] By adopting the above technical solution, adjusting the locking parts, and pulling the handle to move the baffle two, the activated carbon adsorption plate is moved out of the adsorption box, which improves the convenience of cleaning and replacing the surface of the activated carbon adsorption plate.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The auger conveys the resin to the top of the stirring rod, where the stirring rod performs initial stirring of the resin. When the resin falls into the collection basket, it impacts the screen, causing the screen to descend. The second sliding block compresses the spring. When the spring returns to its original position, the second sliding block drives the screen to move upward. The reciprocating movement of the screen ensures that the resin is evenly distributed in the collection basket, thus improving the uniformity of the resin in the collection basket.

[0027] 2. When the original resin is completely removed, push the bottom sliding plate to block the opening of the bottom storage basket. The groove and the protrusion work together to fix the bottom sliding plate. As resin is continuously added, motor five drives gear two to rotate. Gear two causes rack two to move laterally. The connecting shaft drives the sliding plate to block the opening of the second opening through the connecting rod, which improves the convenience of the sliding plate to block the opening of the second opening.

[0028] 3. When it is necessary to clean the activated carbon adsorption plate, adjust the locking device and pull the handle to move the baffle plate and the activated carbon adsorption plate out of the adsorption box, which improves the stability of the activated carbon adsorption plate cleaning and replacement process.

A remote monitoring device 112 is provided on one side of the resin exchange device 2. The remote monitoring device 112 is used to monitor the water pressure inside the resin exchange device 2 and adjust the liquid flow rate and the on / off state of the water pump 111 in a timely manner.

[0039] Reference Figure 1 and Figure 2The resin exchange device 2 includes an exchange box 21, multiple storage baskets 22, and multiple permeable plates. The accompanying drawings of this application show the resin exchange device 2 in the process of resin replacement. The exchange box 21 is vertically arranged, and the end of the infusion pipe 11 furthest from the filter device 1 is connected to the upper end of the exchange box 21, delivering palladium-ion-containing liquid into the exchange box 21. Multiple openings 211 are opened on one side of the exchange box 21. The storage baskets 22 and permeable plates are correspondingly located inside the exchange box 21. The storage baskets 22 slide within the openings 211 along their length. The permeable plates are located below and in contact with the storage baskets 22. The permeable plates are fixedly connected to the inside of the exchange box 21 and are horizontally arranged, supporting the storage baskets 22. The storage baskets 22 are slidably connected to the permeable plates along the horizontal direction. The lower end of the storage basket 22 has an opening 221. After the palladium ion liquid is adsorbed by the resin in the storage basket 22, the remaining liquid enters the next process through the permeable plate.

[0040] Reference Figure 1 and Figure 2 Multiple storage baskets 22 are fixed to the same support plate 222 near the opening 211. The support plate 222 is vertically arranged, and a rack 242 is fixed to one longitudinal side of the support plate 222. The rack 242 is horizontally arranged and slidably connected to the exchange box 21 along its own length. When the rack 242 moves, it drives the support plate 222 to move. A motor 24 is fixed to the outside of the exchange box 21. A gear 241 is fixed to the output shaft of the motor 24. The gear 241 meshes with the rack 242.

These protrusions 225 are evenly arranged laterally and made of elastic material. The support plate 222 has a groove that communicates with the support opening 223. When the bottom sliding plate 224 slides, the protrusions 225 are located in the groove, and the protrusions 225 and the groove cooperate to limit the bottom sliding plate 224. A moving device 25 is provided on the outside of the exchange box 21. The moving device 25 is used to drive the remaining sliding plate 224 to seal the opening 221 of the storage basket 22, improving the convenience of resin replacement and storage.

Multiple stirring rods 46 are fixedly connected to the lower end of the rotating shaft 45 and are evenly arranged around the circumference of the rotating shaft 45. Motor 3 44 drives the rotating shaft 45 to rotate. Multiple stirring rods 46 perform preliminary stirring of the resin, so that the resin enters the collection basket 22 evenly, improving the uniformity of the resin in the collection basket 22.

[0044] Reference Figure 2 and Figure 4The passage 221 is equipped with a material leveling component 47, which is used to evenly distribute the resin in the storage basket 22.

One end of the spring 475 is fixedly connected to the second slider 479, and the other end of the spring 475 is fixedly connected to the uniform material plate 471. When the resin falls into the storage basket 22, the resin comes into contact with the screen 472 and exerts an impact force on the screen 472. The screen 472 slides vertically in the three openings 477. The screen 472 drives the sliding block 2 to slide in the sliding groove 478. The sliding block 2 squeezes the spring 475. When the impact force disappears, the spring 475 returns to its original position, causing the screen 472 to move upward. Through the reciprocating movement of the screen 472, the resin is evenly distributed in the storage basket 22.

A slider 476 is installed within the sliding opening 227 and is slidably connected to the storage basket 22. The slider 476 is fixedly connected to a uniform material plate 471. Movement of the slider 476 moves the uniform material plate 471. A motor 473 is fixedly connected to the side of the storage basket 22 away from the uniform material plate 471 and located at the upper end of the storage basket 22. A lead screw 474 is fixedly connected to the output shaft of the motor 473 and rotates coaxially with the output shaft. The lead screw 474 passes through the slider 476 and is threadedly connected to it. Rotation of the lead screw 474 causes the slider 476 to rise and fall vertically. As resin is added, the motor 473 drives the lead screw 474 to rotate, causing the slider 476 to rise in the sliding opening 227. The slider 476 then moves the uniform material plate 471 upward, further improving the uniformity of the resin within the storage basket 22.

[0046] Reference Figure 4A shielding plate 226 is provided inside the sliding port 227. The shielding plate 226 is set vertically and fixedly connected to the storage basket 22. The shielding plate 226 passes through the slider 476 and is slidably connected to the slider 476 vertically. When the slider 476 moves, the slider 476 moves along the length of the shielding plate 226. The shielding plate 226 is used to shield the sliding port 227, which helps to reduce the probability of resin splashing from the sliding port 227 during resin removal and addition, and improves the stability of resin removal and addition.

[0048] Reference Figure 5 and Figure 6 When the resin is full in the storage basket 22, the motor 251 drives the gear 253 to rotate. The gear 253 causes the rack 252 to move laterally. At this time, the elastic element 256 on the lower connecting shaft 254 is located in the positioning port 257 of the lower connecting rod 255. The movement of the rack 252 drives the middle connecting rod 255 to move. The lower connecting rod 255 drives the middle sliding plate 224 to move.

The activated carbon adsorption device 3 is used to further adsorb the liquid after it has been adsorbed by the resin exchange device 2. A second infusion pipe 31 is provided between the resin exchange device 2 and the activated carbon adsorption device 3. The lower end of the exchange box 21 is connected to the second infusion pipe 31. The liquid in the resin exchange device 2 flows into the activated carbon adsorption device 3 from the second infusion pipe 31.

[0050] Reference Figure 1 The activated carbon adsorption device 3 includes an adsorption box 32 and multiple activated carbon adsorption plates 33. The adsorption box 32 is vertically arranged. The end of the infusion pipe 31 away from the exchange box 21 is connected to the upper end of the adsorption box 32. The lower end of the adsorption box 32 is connected to a discharge pipe 34 for discharging the adsorbed liquid. A flow equalization plate is fixed inside the adsorption box 32. The flow equalization plate is horizontally arranged and located at the upper end of the adsorption box 32. The liquid flows into the adsorption box 32 from the infusion pipe 31, and the flow equalization plate makes the palladium ion-containing liquid flow evenly in the adsorption box 32. The multiple activated carbon adsorption plates 33 are located inside the adsorption box 32 and arranged vertically. The pore size of the activated carbon in the multiple activated carbon adsorption plates 33 decreases from top to bottom. The liquid passes through the multiple activated carbon adsorption plates 33, and the activated carbon adsorption plates 33 adsorb palladium ions in the liquid.

[0051] Reference Figure 1 The adsorption box 32 has a transverse opening 36. A sliding member 35 is provided between the activated carbon adsorption plate 33 and the adsorption box 32. The sliding member 35 is used to move the activated carbon adsorption plate 33 and to block the opening 36. The sliding component 35 includes multiple connecting blocks 351 and a second baffle 352. The second baffle 352 is located inside the second opening 221. A sealing ring is provided at the connection between the second baffle 352 and the adsorption box 32, and it is fixedly connected to the activated carbon adsorption plate 33. The multiple connecting blocks 351 are fixedly connected to the inner side of the adsorption box 32 and are set perpendicular to the second baffle 352. The activated carbon adsorption plate 33 is located between the multiple connecting blocks 351 and is slidably connected to the connecting blocks 351 along the length direction of the connecting blocks 351. A handle 353 is fixedly provided on the side of the second baffle 352 away from the adsorption box 32. A locking component 354 is provided between the second baffle 352 and the adsorption box 32. By adjusting the locking component 354 and pulling the handle 353, the second baffle 352 moves the activated carbon adsorption plate 33, and the activated carbon adsorption plate 33 is moved out of the adsorption box 32, which improves the convenience of cleaning the surface of the activated carbon adsorption plate 33.

[0052] The implementation principle of a palladium ion recovery device in this application embodiment is as follows: the filter device 1 first removes solid particles from the liquid containing palladium ions, and the resin exchange device 2 adsorbs palladium ions into the liquid filtered by the filter device 1. When resin needs to be replaced, motor 24 rotates, gear 241 rotates, causing rack 242 to slide, so that the collection basket 22 slides in the opening 211 and moves away from the exchange box 21. The resin passes through the opening 221 and falls into the recycling tank 23, pushing the bottom sliding plate 224 to block the opening 221 of the bottom collection basket 22. The auger 42 transports the resin, and the stirring rod 46 initially stirs the resin, so that the resin falls evenly into the collection basket 22. When the resin falls into the collection basket 22, the resin contacts the screen 472 and generates an impact force on the screen 472. The screen 472 slides vertically in the opening 477. The screen 472 drives the sliding block 2 to slide in the sliding groove 478, and the sliding block 2 compresses the spring 475. When the impact force disappears, the spring 475 resets, causing the screen 472 to move upward. The reciprocating movement of the screen 472 makes the resin evenly distributed in the collection basket 22. The slider 476 drives the uniform plate 471 to rise, which evenly distributes the resin above, improving the uniformity of the resin in the collection basket 22. When the collection basket 22 is full of resin, the connecting shaft 254 drives the sliding plate 224 to move through the connecting rod 255 to block the opening 221 of the collection basket 22. The rack 242 drives the collection basket 22 into the exchange box 21. Multiple activated carbon adsorption plates 33 further adsorb the palladium ion-containing waste liquid. The resin replacement process of the resin exchange device 2 reduces manual operation, which helps to reduce the manpower and time of the replacement process and improves the convenience of resin replacement.

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