[0001] The invention relates to the technical field of cobalt and nickel recovery, and in particular to a cobalt and nickel separation mechanism in a manganese sulfate solution. Background Art

[0002] Chinese patent publication number CN116970816A discloses a method for recovering battery-grade nickel sulfate crystals and battery-grade cobalt sulfate crystals from a complex nickel-cobalt-manganese sulfate solution, and the specific operation is as follows: Step 1): Use a neutralizer to adjust the pH of the complex nickel-cobalt-manganese sulfate solution to 1.5-2.5 as a P204 extraction liquid; Use di(2-ethylhexyl) phosphate and No. 260 solvent oil to prepare a P204 extractant, and use a saponifier to saponify the P204 extractant; Use the saponified P204 The extractant extracts the P204 extract solution to obtain a P204 organic phase and a P204 aqueous phase; the P204 aqueous phase is a nickel cobalt magnesium sulfate solution; step 2): using a neutralizer to adjust the pH of the nickel cobalt magnesium sulfate solution obtained in step 1) to 4.0-4.5 to prepare a P507 extract solution; using 2-ethylhexyl phosphate 2-ethylhexyl ester and No. 260 solvent oil to prepare a P507 extractant, using a saponifier to saponify the P507 extractant; using the saponified P507 extractant to extract the P507 The feed liquid is extracted to obtain a P507 organic phase and a P507 aqueous phase; the P507 aqueous phase is a nickel-magnesium sulfate solution; the P507 organic phase is washed with 1.2-1.3 mol / L sulfuric acid, and the washed P507 organic phase is back-extracted with 4.0-5.0 mol / L sulfuric acid to obtain a cobalt sulfate solution; step 3): using a neutralizer to adjust the pH of the nickel-magnesium sulfate solution obtained in step 2) to 4.5-5.0 as a C272 extraction feed liquid; using 2-ethylhexyl phosphate 2-ethylhexyl The extractant C272 is prepared by mixing 2,4,4-trimethylpentyl phosphinic acid, di(2,4,4-trimethylpentyl)phosphinic acid and No. 260 solvent oil, and the C272 extractant is saponified by using a saponifying agent; the C272 extractant is used to extract the C272 extract liquid to obtain a C272 organic phase and a C272 aqueous phase; the C272 aqueous phase is a nickel sulfate solution; step 4): the cobalt sulfate solution obtained in step 2) and the nickel sulfate solution obtained in step 3) are evaporated and crystallized to obtain battery-grade cobalt sulfate crystals and battery-grade nickel sulfate crystals.

[0003] In step 1), a neutralizing agent is used to adjust the pH of the complex nickel-cobalt-manganese sulfate solution to 1.5-2.5 as the P204 extraction feed solution. When the neutralizing agent is added to the reactor containing the nickel-cobalt-manganese sulfate solution, the following two situations may occur:

[0004] First, when adding the reaction neutralizer, most of them are added at the feed inlet. Since the neutralizer is not preheated in advance, the activity of the neutralizer is not high, and it is difficult for the reaction neutralizer entering the reactor to react quickly with the manganese sulfate solution;

[0005] Second, the concentration of the neutralizer is too high, so the manganese sulfate solution reacts too quickly with the newly added neutralizer, and the other manganese sulfate solutions have no time to react, and the neutralizer is completely diluted;

[0006] 3. The uneven contact between the reaction neutralizer and the manganese sulfate solution after being added at the same time will also cause the solution in the reactor to react incompletely.

[0007] Therefore, the present application provides a cobalt-nickel separation mechanism in a manganese sulfate solution to meet the demand. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide a cobalt-nickel separation mechanism in a manganese sulfate solution to solve the existing problems that: when adding a reaction neutralizer, most of them are added at a feed inlet. Since the neutralizer is not preheated in advance, the activity of the neutralizer is not high, and it is difficult for the reaction neutralizer entering the reactor to react quickly with the manganese sulfate solution; the concentration of the neutralizer is too high, so the manganese sulfate solution at this time reacts too quickly with the newly added neutralizer, and other manganese sulfate solutions have no time to react, and the neutralizer is completely diluted; at the same time, the added reaction neutralizer is not in uniform contact with the manganese sulfate solution, which also causes the solution in the reactor to react incompletely.

[0018] Optionally, a conical head is installed at the end of the limiting rod, and a groove is formed on the outer surface of the top of the limiting rod. The position of the conical head is exactly at the top of the moving path of the conical gravity block.

[0022] Optionally, the liquid flow assembly includes a hose, which is installed at the bottom of the rotating cover and connected to the feed tube. A heating box is installed at the bottom of the hose, and a heating wire is arranged in the heating box. The heating box is connected to the top of the reagent cartridge of the first group through the feed tube, and side tubes are installed on both sides of the heating box, and the side tubes are connected to the top of the reagent cartridges of the second and third groups.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] In the above scheme, by setting a driving component, the driving circulation component drives the dosing component to move horizontally left and right on the inner wall of the reactor, so that when the reagent cylinder moves to the left, the conical gravity block below the reagent cylinder is driven to move to the left, and the conical gravity block is pushed upward by the conical head, driving the piston to move upward, and the preheated neutralizer is squeezed out of the spray pipe and evenly sprayed in the manganese sulfate solution inside the reactor. At the same time, the kinetic energy generated during the spraying and the kinetic energy of the dosing component moving horizontally left and right on the inner wall of the reactor, including the upper fixing frame, the bottom fixing frame and the fixing rod, will stir the manganese sulfate solution mixture when rotating, thereby accelerating the reaction rate.

[0025] By setting a driving component, the driving circulation component drives the dosing component to move horizontally on the inner wall of the reactor. When the inner wall of the reactor moves to the right, the conical gravity block will fall from the top of the limit rod and pull the piston downward by its own gravity. At this time, the manganese sulfate solution is sucked into the reagent cylinder by the piston. At the same time, the neutralizer in the reagent tray that flows into the heating box through the dosing tube and the hose for temporary storage and continuous heating is also sucked in through the side tube and the feed tube, and mixed with the manganese sulfate solution just sucked in in the small space of the reagent cylinder. The reaction neutralizer is preliminarily mixed with a small amount of manganese sulfate solution. Mixing will increase the concentration of the mixed solution and dilute the reaction neutralizer to prevent the reaction neutralizer from being too concentrated and reacting too quickly with the manganese sulfate solution, causing part of the reaction neutralizer to not be completely reacted. Finally, when it reciprocates to the left again, it will repeat the previous operation to spray out the mixed solution of manganese sulfate solution and neutralizer, and repeat this cycle, which can not only increase the uniformity of the neutralizer added to the manganese sulfate solution, but also heat the neutralizer in advance, improve the activity of the neutralizer, and make the neutralizer react faster when it contacts with the manganese sulfate solution.

[0026] By setting the blocking component, when the piston is pushed to the top by the conical gravity block, the push rod on the top of the piston will lift the blocking plug of the blocking component, and the blocking plug will no longer block the opening at the top of the piston. At the same time, when the internal threaded slider continues to move to the left on the bidirectional screw, the bottom end of the conical gravity block has just reached the top of the limit rod and moves to the left at the top of the limit rod. At the same time, the rotating column at the bottom of the conical gravity block and the multiple groups of corrugated bars installed on the outer surface move on the multiple groups of grooves at the top of the limit rod. When the rotating column with multiple groups of corrugated bars rotates and the ups and downs under the multiple groups of grooves, the conical gravity block vibrates and transmits the vibration to the piston. At this time, the remaining neutralizer on the piston will flow out from the opening and into the manganese sulfate solution, preventing the remaining liquid on the top of the piston from being squeezed out, thereby improving the reliability and stability of the dosing component and making the reaction neutralizer discharged more thoroughly in the reagent cylinder.

[0049] A circulation assembly 6 is installed at the bottom of the driving assembly 2, and the circulation assembly 6 is used to drive the liquid spraying pipe 42 to move in a circulation manner;

[0050] A dosing assembly 4 is installed at one end of the circulation assembly 6, and the dosing assembly 4 is used to spray the added neutralizing agent evenly in the manganese sulfate solution;

[0051] The inner wall of the dosing component 4 is plugged with a blocking component 5 , and the blocking component 5 is used to shake out the remaining neutralizing agent in the dosing component 4 after the dosing component 4 squeezes out all the neutralizing agent.

[0052] As an implementation method in this embodiment, Figure 2 - Figure 5 As shown, the driving assembly 2 includes a reduction motor 20, which is installed on the bottom inner wall of the reactor 10. An upper fixing frame 21 is installed at the output end of the reduction motor 20, a side rod 22 is installed at the bottom of the upper fixing frame 21, and a bottom fixing frame 23 is installed at the bottom end of the side rod 22.

[0053] In this embodiment, the upper fixing frame 21 and the bottom fixing frame 23 are both set to be ring-shaped, and the material is set to be a lightweight aluminum alloy with good corrosion resistance. While reducing the weight, the service life can be extended. By opening the rotating cover 15 on the top of the reactor 10, the upper fixing frame 21 and the bottom fixing frame 23 can be conveniently lifted out as a whole, and the liquid passing component 3, the dosing component 4 and the circulation component 6 can be taken out for maintenance and inspection.

[0054] As an implementation method in this embodiment, Figures 3 to 5 As shown, the circulation component 6 includes a fixed rod 60, which is installed on the top of the bottom fixed frame 23, a bidirectional screw 61 is inserted into the outer surface of one side of the fixed rod 60, a gear 62 is installed at the left end of the bidirectional screw 61, a limiting rod 63 is installed on the outer surface of one side of the fixed rod 60, an internally threaded slider 64 is threadedly connected to the inner wall of the bidirectional screw 61, the limiting rod 63 is inserted into the outer surface of one side of the internally threaded slider 64, and a mounting seat 65 is installed on the top of the internally threaded slider 64.

[0055] The number of circulation components 6 is set to multiple groups, the bottom of the gear 62 is meshed with the gear ring 12, the bidirectional screw 61 is rotatably connected to the inner wall of the fixed rod 60, the internal threaded slider 64 can slide left and right on the surface of the bidirectional screw 61, and the limit rod 63 is slidably connected to the internal threaded slider 64.

[0056] In this embodiment, by starting the reduction motor 20, the upper fixing frame 21 is driven to start rotating, and the upper fixing frame 21 drives the bottom fixing frame 23 to rotate through the side rod 22. At this time, the bottom fixing frame 23 drives the fixing rod 60 to rotate along the inner wall of the reactor 10, and at the same time, the rotating cover 15, the dosing tube 140 and the reagent disk 14 will also rotate along the top of the reactor 10. At this time, the fixing rod 60 drives the gear 62 to rotate on the gear ring 12 meshing therewith, and the gear 62 drives the bidirectional screw 61 to rotate. At this time, when the bidirectional screw 61 rotates, the internal threaded slider 64 will be limited by the limiting rod 63 and move horizontally on the inner wall of the reactor 10. The kinetic energy generated by the horizontal movement of the internal threaded slider 64 on the inner wall of the reactor 10, including the upper fixing frame 21, the bottom fixing frame 23 and the fixing rod 60, will stir the manganese sulfate solution mixture when rotating;

[0057] As an implementation method in this embodiment, Figures 6 to 12 As shown, a liquid-passing assembly 3 is installed at the top of the dosing assembly 4, and the liquid-passing assembly 3 is used to provide a channel for the neutralizer in the dosing assembly 4 to flow out. The dosing assembly 4 includes a reagent cartridge 40, and the number of reagent cartridges 40 is set to three groups. The three groups of reagent cartridges 40 are installed on the top of the mounting seat 65, and a liquid spray tube 42 is installed at the center of the top of the reagent cartridge 40. A feed tube 48 is installed on the top of the reagent cartridge 40. A piston 47 is inserted into the inner wall of the reagent cartridge 40, and a conical gravity block 46 is installed at the bottom of the piston 47. A push rod 460 is installed on the top of the conical gravity block 46. A rotating column 461 is installed on the inner wall of the bottom of the conical gravity block 46, and multiple groups of ribs 462 are installed on the outer surface of the rotating column 461. One third of the rotating column 461 is exposed outside the conical gravity block 46; the blocking assembly 5 includes a blocking plug 50, which is installed on the inner wall of the opening 49, and the top of the blocking plug 50 A sealing ring 51 is installed; an opening 49 is provided on the top surface of the piston 47, a bottom limit ring 470 is installed on the bottom edge of the opening 49, an elastic pull rope 471 is installed on one side of the bottom limit ring 470, and the top of the elastic pull rope 471 is connected to the agent blocking plug 50; the liquid flow component 3 includes a hose 30, the hose 30 is installed at the bottom of the rotating cover 15, the hose 30 is connected to the dosing tube 140, a heating box 31 is installed at the bottom of the hose 30, a heating wire is arranged in the heating box 31, the heating box 31 is connected to the top of the first group of reagent cartridges 40 through the feed tube 48, side tubes 32 are installed on both sides of the heating box 31, and the side tubes 32 are connected to the top of the second and third groups of reagent cartridges 40; a conical head 630 is installed at the end of the limit rod 63, a groove 631 is provided on the outer surface of the top of the limit rod 63, and the position of the conical head 630 is just at the top of the moving path of the conical gravity block 46.

[0058] In this embodiment, the reagent first flows from the reagent disk 14 into the dosing tube 140, and then flows from the dosing tube 140 into the hose 30, and then enters the heating box 31 from the hose 30, and is heated by the heating wire of the heating box 31 to increase the activity of the neutralizer, and finally flows into the neutralizer in the three groups of reagent cartridges 40 through the inlet tube 48 and the side tube 32 respectively. The internal threaded slider 64 is limited by the limit rod 63, and moves horizontally to the left and right of the inner wall of the reactor 10, driving the reagent cartridge 40 to move to the left, and driving the conical gravity block 46 under the reagent cartridge 40 to move to the left. Due to the conical head 63 The position of 0 is just at the top of the moving path of the conical gravity block 46. At this time, the conical head 630 will start to push the conical gravity block 46. After being pushed, the conical gravity block 46 moves upward, driving the piston 47 to push upward, squeezing the neutralizer from the spray pipe 42 and spraying it evenly in the manganese sulfate solution inside the reactor 10 (since the bottom ends of the feed pipe 48 and the side pipe 32 are both provided with a one-way valve, the neutralizer will not flow back from here). When the piston 47 is pushed to the top by the conical gravity block 46, the top rod 460 at the top of the conical gravity block 46 will block the piston 47. The stopper plug 50 of the agent assembly 5 is lifted up to expose the opening 49 at the top of the piston 47. At this time, the elastic pull rope 471 at the bottom of the stopper plug 50 is pulled to limit and reset the position of the stopper plug 50. At the same time, when the internal threaded slider 64 continues to move to the left on the bidirectional screw 61, the bottom end of the conical gravity block 46 has just reached the top of the limit rod 63 and moves to the left at the top of the limit rod 63. At the same time, the rotating column 461 at the bottom of the conical gravity block 46 and the multiple groups of ribs 462 installed on the outer surface move on the multiple groups of slots 631 at the top of the limit rod 63. When the rotating column 461 with multiple groups of ribs 462 rotates and the multiple groups of slots 631 rise and fall, the conical gravity block 46 vibrates and transmits the vibration to the piston 47. At this time, the remaining neutralizer on the piston 47 will flow out from the opening 49 and flow into the manganese sulfate solution to prevent the remaining liquid on the top of the piston 47 from being squeezed out; the top of the piston 47 is set to be concave, which is more conducive to the discharge of the remaining liquid. A sealing ring 51 is installed on the top of the agent blocking plug 50, and the sealing ring 51 is used to seal between the opening 49 and the agent blocking plug 50.

[0059] The internal threaded slider 64 is limited by the limit rod 63. When the inner wall of the reactor 10 moves to the right, the conical gravity block 46 will fall from the top of the limit rod 63 and pull the piston 47 downward by its own gravity. At this time, the piston 47 has a good sealing performance with the inner wall of the reagent cylinder 40. At the same time, the gravity of the conical gravity block 46 is greater than the sum of the friction between the piston 47 and the reagent cylinder 40 and the suction force of the manganese sulfate solution from the spray pipe 42. At this time, the manganese sulfate solution is sucked into the reagent cylinder 40 by the piston 47. At the same time, the neutralizer in the reagent disk 14 that flows into the heating box 31 through the dosing tube 140 and the hose 30 and is temporarily stored and continuously heated is continuously sucked in through the side tube 32 and the inlet tube 48, and mixed with the manganese sulfate solution just sucked in the small space of the reagent cylinder 40. The reaction neutralizer is pre-mixed with a small amount of manganese sulfate solution, which will increase the concentration of the mixed solution and dilute the reaction neutralizer at the same time to prevent the reaction neutralizer from being too concentrated and reacting too quickly with the manganese sulfate solution, resulting in part of the reaction neutralizer not being completely reacted.

[0060] The working principle provided by the present invention is that the staff first pours the manganese sulfate solution into the reactor 10 through the feed port 11, and flows from the reagent tray 14 into the dosing tube 140, and then flows from the dosing tube 140 into the hose 30, and then enters the heating box 31 from the hose 30, and is heated by the heating wire of the heating box 31 to increase the activity of the neutralizer. After heating to a certain temperature, the control center opens the valve of the heating box 31, and the neutralizer in the heating box 31 flows into the three groups of reagent cylinders 40 through the feed tube 48 and the side tube 32. Then the staff turns on the reduction motor 20 to drive the upper fixed frame 21 to start rotating, and the upper fixed frame 21 drives the bottom fixed frame 2 through the side rod 22 3 rotates, at this time, the bottom fixing frame 23 drives the fixing rod 60 to rotate along the inner wall of the reactor 10, and at the same time, the rotating cover 15, the dosing tube 140 and the reagent disk 14 will also rotate along the top of the reactor 10, at this time, the fixing rod 60 drives the gear 62 to rotate on the gear ring 12 meshing therewith, and the gear 62 drives the bidirectional screw 61 to rotate. When the bidirectional screw 61 rotates, the internal thread slider 64 will be limited by the limiting rod 63 and move horizontally on the inner wall of the reactor 10. The kinetic energy generated by the horizontal movement of the internal thread slider 64 on the inner wall of the reactor 10, including the upper fixing frame 21, the bottom fixing frame 23 and the fixing rod 60, will stir the manganese sulfate solution mixture when they rotate.

[0061] When the internal threaded slider 64 moves horizontally left and right on the inner wall of the reactor 10, it will drive the reagent cylinder 40 to move left, and simultaneously drive the conical gravity block 46 below the reagent cylinder 40 to move left. Since the position of the conical head 630 is exactly at the top of the moving path of the conical gravity block 46, the conical head 630 will start to push the conical gravity block 46 at this time. After being pushed, the conical gravity block 46 moves upward, driving the piston 47 to push upward.

[0062] When the piston 47 is pushed upward, the neutralizer in the three groups of reagent cartridges 40 is squeezed out from the spray pipe 42 and evenly sprayed in the manganese sulfate solution inside the reactor 10 (since the bottom ends of the feed pipe 48 and the side pipe 32 are both provided with a one-way valve, the neutralizer will not flow back from here). When the piston 47 is pushed to the top by the conical gravity block 46, the push rod 460 on the top of the conical gravity block 46 will push up the stopper plug 50 of the stopper assembly 5, and the stopper plug 50 will no longer block the opening 49 at the top of the piston 47. At this time, the elastic pull rope 471 at the bottom of the stopper plug 50 is pulled to limit and return the position of the stopper plug 50. At the same time, the internal threaded slider 64 continues to move in the bidirectional screw 61 moves to the left, at this time, the bottom end of the conical gravity block 46 has just reached the top of the limiting rod 63, and moves to the left at the top of the limiting rod 63. At the same time, the rotating column 461 at the bottom of the conical gravity block 46 and the multiple groups of ribs 462 installed on the outer surface move on the multiple groups of slots 631 at the top of the limiting rod 63. When the rotating column 461 with the multiple groups of ribs 462 rotates and the multiple groups of slots 631 rise and fall, the conical gravity block 46 vibrates and transmits the vibration to the piston 47. At this time, the remaining neutralizer on the piston 47 will flow out from the opening 49 and into the manganese sulfate solution to prevent the remaining liquid on the top of the piston 47 from being squeezed out.

[0063] The internal threaded slider 64 is limited by the limit rod 63. When the inner wall of the reactor 10 moves to the right, the conical gravity block 46 will fall from the top of the limit rod 63 and pull the piston 47 downward by its own gravity. At this time, the piston 47 has a good sealing performance with the inner wall of the reagent cylinder 40. At the same time, the gravity of the conical gravity block 46 is greater than the sum of the friction between the piston 47 and the reagent cylinder 40 and the suction force of the manganese sulfate solution from the spray pipe 42. At this time, the manganese sulfate solution is sucked into the reagent cylinder by the piston 47. 40, and at the same time, the neutralizer in the reagent disk 14 that flows into the heating box 31 through the dosing tube 140 and the hose 30 and is temporarily stored and continuously heated is continuously sucked in through the side tube 32 and the inlet tube 48, and mixed with the manganese sulfate solution just sucked in in the reagent cylinder 40, and finally the previous operation is repeated to spray out, and this cycle is repeated to increase the uniformity of the neutralizer added to the manganese sulfate solution, and the neutralizer is heated in advance to improve the activity of the neutralizer, so that the neutralizer can react faster when in contact with the manganese sulfate solution.

[0064] By opening the lid on the top of the reactor 10, the upper fixing frame 21 and the bottom fixing frame 23 can be conveniently lifted out as a whole, and the liquid passing assembly 3, the dosing assembly 4 and the circulation assembly 6 can be lifted upward for maintenance and inspection.
