Description

Technical Field

[0001] This invention relates to the field of lithium carbonate preparation technology, specifically an integrated lithium carbonate preparation system. Background Technology

[0002] Lithium carbonate is a colorless monoclinic crystal that is slightly soluble in water and dilute acids, but insoluble in ethanol and acetone. Its thermal stability is lower than that of carbonates of other elements in the same group in the periodic table. It does not deliquesce in air and can be obtained by adding sodium carbonate to lithium sulfate or lithium oxide solution.

[0003] Lithium carbonate has important applications in the new energy field because it is the main component of the cathode of lithium-ion batteries. In addition, lithium carbonate can be used to produce electrolytes in the electronics industry; and in the glass production process, it can be used as a colorant or to improve other properties.

[0004] Currently, in the process of lithium carbonate preparation, the ore raw materials need to be crushed, leached and crystallized to obtain lithium carbonate crystals.

The top of the positioning frame 11 is fixedly connected to the transmission frame 16.

[0045] In detail, each end of the stirring rod 8 located inside the leaching tank 7 is fixedly connected with a stirring plate, and the number of stirring plates is not less than two. By using the stirring plates, the stirring range of the stirring rod 8 can be greatly improved, so that the lithium carbonate ore raw material can react more fully with the acid solution.

[0046] The top of the leaching tank 7 is fixedly connected to a liquid filling pipe;

[0047] The leaching mechanism 2 also includes a central shaft 17, an eccentric transmission plate 18, a linkage rod 19, a transmission motor 20, a transmission bevel gear 21, a discharge pipe 22, an extension frame 23, a guide slide rod 24, a sealing frame 25, and a hydraulic rod 26.

A hydraulic rod 26 is fixedly connected to the side of the leaching tank 7 near the extension frame 23. The output end of the hydraulic rod 26 is fixedly connected to the sealing frame 25.

[0048] More specifically, when the drive motor 20 is started, the eccentric drive plate 18 pulls the displacement plate 13 back to its original position under the limit of the limit slide rod 12 via the linkage rod 19, and drives the drive gear 15 via the drive rack 14, thereby driving the stirring roller 8 connected to the drive gear 15 to rotate, causing multiple stirring rollers 8 to rotate simultaneously, so that the ore raw material and acid solution can react more fully, and the lithium in the ore raw material can be leached out.

[0049] Specifically, the end of the eccentric transmission plate 18 away from the central shaft 17 is fixedly connected to a guide shaft, and one side of the displacement plate 13 is fixedly connected to a linkage shaft. The linkage rod 19 is rotatably connected between the guide shaft and the linkage shaft. By utilizing the structural cooperation between the guide shaft and the linkage shaft, the linkage rod 19 can be assembled more stably and the linkage effect of the linkage rod 19 can be ensured.

[0050] In detail, sealing strips are fixedly connected to the inner wall of the discharge pipe 22 and the outer side of the sealing frame 25. Through the structural design of the sealing strips, the sealing performance when the sealing frame 25 and the discharge pipe 22 are connected can be greatly improved.

[0051] Furthermore, a transmission seat is fixedly connected to the top of the positioning frame 11, and the transmission motor 20 is fixedly connected to the top of the transmission seat by bolts. The transmission seat facilitates the assembly of the transmission motor 20 and makes subsequent maintenance convenient.

[0052] The refining mechanism 3 includes a feed box 27, a barrier screen 28, a feed pipe 29, a refining hopper 30, a crushing roller 31, a linkage spur gear 32, a crushing motor 33, a refining plate 34, a sealing plate 35, and a hydraulic cylinder 36. The feed box 27 is fixedly connected to the top of the leaching tank 7. The barrier screen 28 is fixedly connected to the bottom of the feed box 27. The feed pipe 29 is fixedly connected to one side of the feed box 27 at an angle. The refining hopper 30 is fixedly connected to the top of one end of the feed pipe 29. Two powder refining hoppers are laterally rotatably connected inside the refining hopper 30. The crushing rollers 31 are fixedly connected to one end of each of the two crushing rollers 31, and the two spur gears 32 are meshed together. The fine hopper 30 is fixedly connected to one end of the crushing motor 33, and the output end of the crushing motor 33 is fixedly connected to one of the crushing rollers 31.

[0053] Understandably, lithium carbonate ore is fed into the top of the refining hopper 30 and crushed by the contact between the crushing roller 31 and the lithium carbonate ore. The crushed ore raw material will be received by the barrier screen 28. The ore raw material that meets the preparation specifications will be discharged into the leaching tank 7 through the barrier screen 28. At the same time, the hydraulic cylinder 36 is activated to push the refining plate 34 downward so that the refining plate 34 contacts the ore raw material and crushes it by compression until it meets the specifications for subsequent preparation.

[0054] In detail, the top of the barrier screen 28 has multiple filter holes vertically opened, and the diameter of the filter holes is 5mm.

[0055] Among them, the top of the guide box 27 is slidably connected to a stabilizing slide rod, and one end of the stabilizing slide rod located inside the guide box 27 is fixedly connected to the refining plate 34. By setting the stabilizing slide rod, the displacement of the refining plate 34 can be assisted and guided, thereby ensuring the stability of the application of the refining plate 34.

[0056] Example 2:

[0057] Please see Figure 7 This embodiment provides a technical solution based on Embodiment 1: The crystallization mechanism 5 includes a heating base 37, an electric heating wire 38, a crystallization tank 39, a mixing roller 40, a mixing motor 41, a transfer pump 42, an external inlet pipe 43, a transfer pipe 44, and an outlet pipe 45. The heating base 37 is fixedly connected to the top of the support base 4. The electric heating wire 38 is fixedly connected inside the heating base 37. The crystallization tank 39 is fixedly connected to the top of the heating base 37. The mixing roller 40 is vertically rotatably connected to the middle of the crystallization tank 39. The top of the crystallization tank 39... A mixing motor 41 is fixedly connected, and the output end of the mixing motor 41 is fixedly connected to the mixing roller 40. A transfer pump 42 is fixedly connected to the top of one end of the support base 4. An external lead pipe 43 is fixedly connected to the input end of the transfer pump 42, and the end of the external lead pipe 43 away from the transfer pump 42 is connected to the leaching tank 7. A transfer pipe 44 is fixedly connected to the output end of the transfer pump 42, and the top end of the transfer pipe 44 is connected to the crystallization tank 39. An outlet pipe 45 is fixedly connected to the bottom of the outside of the crystallization tank 39, and one end of the outlet pipe 45 is connected to the centrifuge 6.

[0058] In summary, the electric heating wire 38 is activated to heat the sodium carbonate solution to the required temperature, and the transfer pump 42 is activated to transfer the solution leached from the leaching tank 7 into the crystallization tank 39 to react with the sodium carbonate solution. After mixing, the solution is left to stand and age, allowing the lithium carbonate crystals to grow inside the feed tube 29.

[0059] Preferably, a pipe is fixedly connected to the top of the outer side of the crystallization tank 39 for adding solution into the crystallization tank 39, and a sealing cap is connected to the top of the pipe by a thread.

[0060] Here, a filter screen is fixedly connected inside the end of the external inlet pipe 43 near the leaching tank 7. By setting the filter screen, it is possible to prevent debris from entering the external inlet pipe 43 and causing damage to the transfer pump 42.

[0061] A solenoid valve is installed in the middle of the outlet pipe 45 to control the opening and closing of the outlet pipe 45.

[0062] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0063] During operation, the crushing motor 33 is first started, driving the connected crushing roller 31 to rotate. The connection between the two linked spur gears 32 transmits the power of the crushing motor 33, causing the two crushing rollers 31 to rotate simultaneously in opposite directions. Then, lithium carbonate ore is fed from the top of the refining hopper 30, where it is crushed through contact with the crushing rollers 31. The crushed ore is then fed into the feed box 27 via the feed pipe 29 and received by the barrier screen 28. Ore meeting the required specifications is discharged through the barrier screen 28 into the leaching tank 7. Inside, ore raw materials that do not meet the preparation specifications will remain at the top of the barrier screen 28. At the same time, the hydraulic cylinder 36 is activated to push the refining plate 34 downward, so that the refining plate 34 comes into contact with the ore raw materials and performs extrusion refining until it meets the specifications for subsequent preparation. During the downward movement of the refining plate 34, the sealing plate 35 can be used to block the feed pipe 29 to prevent the ore raw materials from being discharged to the top of the refining plate 34. During the upward movement of the refining plate 34, the sealing plate 35 simultaneously releases the separation from the feed pipe 29, so that some of the ore raw materials inside the feed pipe 29 can be discharged to the barrier screen 28.

[0064] After the ore raw material enters the leaching tank 7, acid is added into the leaching tank 7, and the drive motor 20 is started. With the connection between the two drive bevel gears 21, the central shaft 17 rotates. With the connection between the central shaft 17 and the eccentric drive plate 18, the eccentric drive plate 18 pulls the displacement plate 13 back to the starting position under the limit of the limit slide rod 12 through the linkage rod 19. It also drives the drive gear 15 through the transmission rack 14, thereby driving the stirring rod 8 connected to the drive gear 15 to rotate. With the setting of the linkage belt 10, the power of the rotating stirring rod 8 can be transmitted to cause multiple stirring rods 8 to rotate at the same time. The stirring rods 8 agitate the ore raw material, so that it reacts more fully with the acid and leaches the lithium in the ore raw material.

[0065] After leaching, a sodium carbonate solution is added to the crystallization tank 39, and the electric heating wire 38 is activated. The heat generated by the electric heating wire 38 is introduced into the crystallization tank 39 through the heating base 37, raising the temperature of the sodium carbonate solution inside to the required temperature. The transfer pump 42 is activated to draw the leached solution from the leaching tank 7 out through the external inlet pipe 43 and into the crystallization tank 39 through the transfer pipe 44 to react with the sodium carbonate solution. At the same time, the mixing motor 41 can be activated to drive the mixing roller 40 to rotate, stirring the solution inside the crystallization tank 39 to make the reaction more complete. After mixing, it is left to stand and age, allowing the lithium carbonate crystals to grow inside the feed pipe 29. Subsequently, the solution in the crystallization tank 39 is transferred to the centrifuge 6 through the outlet pipe 45, and the solution is separated by the centrifuge 6 to obtain lithium carbonate crystals.

[0066] The lithium carbonate ore material inside the leaching tank 7 can be discharged by activating the hydraulic rod 26, which pushes the sealing frame 25 to move out of the discharge pipe 22 under the limit of the guide slide rod 24, thereby releasing the blockage of the discharge pipe 22 and allowing the lithium carbonate ore material to be discharged through the discharge pipe 22.
