Description

Technical Field

[0001] This invention belongs to the field of lithium carbonate preparation technology, specifically, it relates to an energy-saving and environmentally friendly lithium carbonate preparation device. Background Technology

[0002] Lithium carbonate is an inorganic compound with the chemical formula Li₂CO₃ and a molecular weight of 73.89. It is a colorless monoclinic crystal, 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 of the periodic table. It does not deliquesce in air and can be obtained by adding sodium carbonate to lithium sulfate or lithium oxide solution. Passing carbon dioxide into its aqueous solution converts it to an acidic salt, and boiling causes hydrolysis. It is used as a raw material in ceramics, glass, ferrites, and for silver paste coating of components.

[0003] Chinese Patent CN116251398A discloses a lithium carbonate preparation apparatus, relating to the field of lithium carbonate preparation technology. The invention includes a cylindrical body and a filter basket. The filter basket is movably disposed inside the cylindrical body, with a limiting sleeve fixed to the bottom of the basket. A rotating rod is rotatably disposed on the bottom surface inside the cylindrical body, with a support plate fixed to its upper end, cooperating with the inner cavity of the limiting sleeve to provide support and stability for the filter basket. A cylindrical cover is movably disposed at the upper end of the cylindrical body, with a top rod rotatably disposed on the cover. A cover plate is fixed to the end of the top rod away from the cover, cooperating with the opening end of the filter basket. A first motor is connected to the upper end of the top rod to drive the filter basket to rotate. Combined with the cleaning fluid inside the cylindrical body, this facilitates the washing of lithium carbonate inside the filter basket. A shell is disposed on the outer side of the cylindrical body, with several heating tubes inside the shell to facilitate the drying of the washed lithium carbonate, thus achieving integrated operation of lithium carbonate washing, filtration, and drying.

[0004] However, in actual use, the aforementioned comparative documents require manual addition of lithium carbonate to the filter basket, making it difficult to control the amount of lithium carbonate added. If too much lithium carbonate is added, the centrifugation efficiency of the lithium carbonate in the middle of the filter basket will be poor. If the weight of the lithium carbonate in the filter basket is unbalanced, the filter basket will easily shake during centrifugation, causing damage.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an energy-saving and environmentally friendly lithium carbonate preparation device.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] An energy-saving and environmentally friendly lithium carbonate preparation apparatus includes a cylindrical body, a filter basket located inside the cylindrical body and having an opening at the top, a basket cover that can be fitted onto the opening of the filter basket, a linkage assembly disposed between the filter basket and the cylindrical body, and a pressing assembly disposed above the cylindrical body. The bottom of the filter basket has a slidable block that can slide along its central axis. The slidable block is connected to the linkage assembly. The telescopic end of the pressing assembly is fixedly connected to the basket cover. The pressing assembly can drive the basket cover to fasten onto the filter basket and press down on the filter basket to trigger the linkage assembly, causing the slidable block to move from a first position to a second position. When the slidable block is in the first position, it protrudes upward relative to the inner bottom surface of the filter basket. When the slidable block is in the second position, its top surface is flush with the inner bottom surface of the filter basket.

The arc-shaped triangular block has a highest point and a lowest point. The arc-shaped drive groove has a first end and a second end. In the initial state where the basket cover is not in contact with the filter basket, the highest point is located on the side closer to the first end. At this time, the lowest point and the second end are far apart from each other. When the basket cover and the filter basket are fastened together, the lowest point is located on the side closer to the first end, and the highest point is located on the side closer to the second end. The drive ring can also be provided with a rubber pad on the lower side to reduce friction and collision with the filter basket. The outer side of the basket cover is equipped with a rod, and the outer side of the filter basket is equipped with a block. The block has a slot, and the slot matches the rod.

[0011] Optionally, the energy-saving and environmentally friendly lithium carbonate preparation device also includes a fixed frame, on which the cylinder is mounted. The pressing assembly includes a C-shaped mounting bracket mounted on the side of the fixed frame, a cylinder mounted on the top of the inner wall of the C-shaped mounting bracket, a concave block mounted on the output end of the cylinder, and a cylinder cover mounted on the lower side of the concave block. The cylinder cover mates with the cylinder. Limiting blocks are installed on both sides of the cylinder cover, and limiting holes are opened on the limiting blocks. A limiting rod that mates with the limiting blocks is installed on the top of the inner wall of the C-shaped mounting bracket, and the limiting rod is located in the limiting hole. An embedding groove that mates with the cylinder is opened on the lower side of the cylinder cover. The cylinder is equipped with a piston rod, which has the same structure as the output end of the cylinder. One end of the piston rod is fixedly connected to the concave block.

[0012] Optionally, a motor is installed on the upper side of the cylinder cover, and the output end of the motor is fixedly connected to the basket cover.

[0013] Optionally, a lifting assembly that cooperates with the filter basket is installed at the bottom of the inner wall of the cylinder. The lifting assembly includes a guide rail installed at the bottom of the inner wall of the cylinder, a housing installed at the center of the bottom of the inner wall of the cylinder, a lifting rod that slides and elastically cooperates with the housing, and a lifting plate that rotates and cooperates with the lifting rod. The lifting plate cooperates with the filter basket, and multiple limiting grooves are provided on the lifting plate. The limiting grooves and the guide rail cooperate with the connecting leg. A rotating ball is installed at the bottom of the connecting leg. The structure of the rotating ball is the same as that of the universal ball in the prior art. It is used to slide in the guide rail. The guide rail is an annular guide rail. A second spring is also installed in the housing. The second spring is installed between the lower side of the lifting rod and the cylinder. A connecting block for connecting with the bottom of the cylinder is also installed on the lower side of the guide rail.

[0014] Optionally, an L-shaped support block is installed on one side of the fixed frame, and a hot air blower is installed on one side of the L-shaped support block. A duct connects the output end of the hot air blower to the cylinder.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0017] 1. The present invention can prevent the excessive amount of lithium carbonate in the filter basket from causing poor centrifugation efficiency by setting a placeholder block inside the filter basket. During the stable downward movement of the basket cover, the stirring component inside the basket cover will stir the lithium carbonate in the filter basket, so that the weight of lithium carbonate in the filter basket is balanced, and the filter basket will not shake during the centrifugation process, which will cause damage.

[0018] 2. The filter in this invention can effectively prevent environmental pollution caused by the cleaning solution after use.

[0019] 3. The present invention uses a lifting component. When the filter basket moves down, it squeezes the lifting plate, causing the second spring to contract. When the basket cover rises, the second spring pushes the filter basket and the dried lithium carbonate inside out of the cylinder. This not only makes it easier for workers to remove the dried lithium carbonate from the filter basket, but also prevents excessive heat loss from the inner cavity of the cylinder, thus saving energy.

[0020] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0033] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0034] The invention will now be described in further detail with reference to the accompanying drawings.

[0035] Please see Figures 1-9 As shown, this embodiment provides an energy-saving and environmentally friendly lithium carbonate preparation device, including a cylindrical body 2, a filter basket 26 located inside the cylindrical body 2 and having an opening at the top, a basket cover 14 that can be fitted onto the opening of the filter basket 26, a linkage assembly disposed between the filter basket 26 and the cylindrical body 2, and a pressing assembly disposed above the cylindrical body 2. The bottom of the filter basket 26 is provided with a slidable block 29 that can slide along its central axis. The slidable block 29 is connected to the linkage assembly. The telescopic end of the pressing assembly is fixedly connected to the basket cover 14. The pressing assembly can drive the basket cover 14 to fasten onto the filter basket 26 and press down the filter basket 26 to trigger the linkage assembly, causing the slidable block 29 to move from a first position to a second position. When the slidable block 29 is in the first position, the slidable block 29 protrudes upward relative to the inner bottom surface of the filter basket 26. When the slidable block 29 is in the second position, the top surface of the slidable block 29 is flush with the inner bottom surface of the filter basket 26.

[0036] Beneficial effects: The placeholder block 29 set inside the filter basket 26 can prevent the filter basket 26 from being filled with too much lithium carbonate, which would cause poor centrifugation efficiency. The lifting component not only makes it easy for the staff to remove the dried lithium carbonate inside the filter basket 26, but also prevents excessive heat loss from the inner cavity of the cylinder 2, thus achieving energy saving.

[0037] like Figure 2 , Figures 5-6 and Figures 8-9 As shown, the filter basket 26 in this embodiment has a cavity 27 at its bottom. The linkage assembly includes multiple linkage components disposed within the cavity 27. The linkage components include a mounting plate 35 mounted on the bottom surface of the cavity 27, a main gear 37 and a secondary gear 39 rotatably fitted on the mounting plate 35, a winding wheel 40 mounted on one side of the secondary gear 39, a pull rope 41 disposed between the winding wheel 40 and the occupant block 29, and a connecting leg 52 slidably fitted within the cavity 27 and meshing with the main gear 37. A main rotating rod 36 and a secondary rotating rod 38 are respectively mounted on one side of the mounting plate 35. The main gear 37 and the secondary gear 39 are respectively mounted on the main rotating rod 36 and the secondary rotating rod 38. The circumference of the main gear 37 is greater than the circumference of the secondary gear 39. A mounting ring 31 is sleeved on the outer side of the occupant block 29. A connecting ring 32 for connecting to the end of the pull rope 41 is disposed on the outer side of the mounting ring 31. The other end of the pull rope 41 is wound around the winding wheel 40. On the reel 40, a protrusion 54 is installed on one side of the connecting leg 52. A rack 33 is installed on the upper side of the protrusion 54 to drive the main gear 37 to rotate when the connecting leg 52 moves. The rack 33 meshes with the main gear 37. Slider blocks are installed on both sides of the connecting leg 52 to slide stably in the cavity 27. A sliding groove is also opened on the inner wall of the cavity 27 to cooperate with the slider. The slider slides in the sliding groove. In order to ensure the stable movement of the rack 33, multiple sets of limiting plates 34 are also installed in the cavity 27 to limit the rack 33. Each set of limiting plates 34 includes two limiting plates 34, and a limiting gap is provided between the two limiting plates 34 to limit the rack 33. A third spring 30 is provided between the lower side of the occupant block 29 and the bottom of the cavity 27. An installation hole 28 is opened between the filter basket 26 and the cavity 27. The occupant block 29 slides in the installation hole 28. Through the set linkage components, when the connecting leg 52 moves upward, it drives the protrusion 54 to move upward. The protrusion 54 drives the rack 33 to move. The movement of the rack 33 drives the main gear 37 to rotate. The rotation of the main gear 37 drives the secondary gear 39 to rotate. The rotation of the secondary gear 39 drives the secondary rotating rod 38 to rotate. The rotation of the secondary rotating rod 38 drives the winding wheel 40 to rotate, thereby causing the pull rope 41 to pull the mounting ring 31 to move downward. The downward movement of the mounting ring 31 drives the placeholder block 29 to move downward, thereby causing the placeholder block 29 to retract into the cavity 27, preventing the placeholder block 29 from affecting the centrifugal effect.

[0038] like Figures 2-4 and Figure 9As shown, a stirring assembly is provided on the lower side of the basket cover 14 in this embodiment. The stirring assembly includes a mounting rod 15 mounted on the lower side of the basket cover 14, a rotating ring 16 rotatably fitted around the mounting rod 15, a drive ring 22 elastically fitted inside the basket cover 14, a spring mounted between the mounting rod 15 and the rotating ring 16, and multiple stirring rods 18 mounted on the lower side of the rotating ring 16. Multiple arc-shaped drive blocks 23 are mounted on the upper side of the drive ring 22, and arc-shaped drive grooves 17 corresponding to the multiple arc-shaped drive blocks 23 are opened on the rotating ring 16. Multiple rectangular grooves 19 are opened on the inner wall of the basket cover 14, and rectangular blocks 20 corresponding to the multiple rectangular grooves 19 are mounted on the outer wall of the drive ring 22. The rectangular blocks 20 are slidably fitted inside the rectangular grooves 19, and a first [missing information] is provided between the upper side of the rectangular block 20 and the top of the rectangular groove 19. A spring 21; an arc-shaped drive block 23 is an arc-shaped triangular block, and the inclined surface of the arc-shaped triangular block cooperates with the arc-shaped drive groove 17. The arc-shaped triangular block has a highest point and a lowest point. The arc-shaped drive groove 17 has a first end and a second end. In the initial state where the basket cover 14 is not in contact with the filter basket 26, the highest point is located on the side closer to the first end. At this time, the lowest point and the second end are far apart from each other. When the basket cover 14 and the filter basket 26 are fastened together, the lowest point is located on the side closer to the first end, and the highest point is located on the side closer to the second end. The lower side of the drive ring 22 can also be provided with a rubber pad to reduce friction and collision with the filter basket 26. A plug rod 24 is installed on the outside of the basket cover 14, and a plug block 25 is installed on the outside of the filter basket 26. A slot is opened on the plug block 25, and the slot cooperates with the plug rod 24. When the basket cover 14 moves down, the filter basket 26 presses against the drive ring 22, causing the drive ring 22 to rise along the rectangular groove 19. The rising drive ring 22 drives the arc-shaped drive block 23 to rise. Under the action of the arc-shaped drive block 23 and the arc-shaped drive groove 17, the rotating ring 16 rotates. The rotating ring 16 rotates and moves multiple stirring rods 18 to stir the lithium carbonate in the filter basket 26, thereby balancing the weight of the lithium carbonate in the filter basket 26 and preventing the filter basket from shaking and being damaged during centrifugation. When the basket cover 14 rises, the drive ring 22 and the rotating ring 16 are reset under the action of the first spring 21 and the spring.

[0039] like Figures 1-3 and Figures 8-9As shown, the energy-saving and environmentally friendly lithium carbonate preparation apparatus of this embodiment also includes a fixed frame 1, a cylindrical body 2 mounted on the fixed frame 1, and a pressing assembly including a C-shaped mounting bracket 6 mounted on the side of the fixed frame 1, a cylinder 7 mounted on the top of the inner wall of the C-shaped mounting bracket 6, a concave block 10 mounted on the output end of the cylinder 7, and a cylinder cover 11 mounted on the lower side of the concave block 10. The cylinder cover 11 cooperates with the cylindrical body 2. Limiting blocks are installed on both sides of the cylinder cover 11, and limiting holes are opened on the limiting blocks. The top of the inner wall of the C-shaped mounting bracket 6 is equipped with a fitting that cooperates with the limiting blocks. A limiting rod 8 is located inside a limiting hole; an embedding groove that mates with the cylinder body 2 is provided on the lower side of the cylinder cover 11; a piston rod 9 is provided on the cylinder 7, and the piston rod 9 and the output end of the cylinder 7 have the same structure, with one end of the piston rod 9 fixedly connected to the concave block 10; a motor 12 is installed on the upper side of the cylinder cover 11 in this embodiment, and the output end of the motor 12 is fixedly connected to the basket cover 14, with the motor 12 located inside the concave block 10; the output end of the motor 12 is set as a rotating rod 13, which passes through the cylinder cover 11 and is fixedly connected to the basket cover 14. When the basket cover 14 needs to rise or fall, the cylinder 7 is activated by the set pressing component. The cylinder 7 drives the concave block 10 to rise or fall through the piston rod 9. The concave block 10 rises or falls, which drives the cylinder cover 11 to rise or fall. The cylinder cover 11 rises or falls, which drives the motor 12 to rise or fall. The motor 12 rises or falls, which drives the basket cover 14 to rise or fall. When it is necessary to drive the basket cover 14 to rotate, the motor 12 is activated. The motor 12 drives the basket cover 14 to rotate through the rotating rod 13, thereby causing the basket cover 14 to drive the filter basket 26 to rotate for centrifugal operation.

[0040] like Figures 7-9 As shown, in this embodiment, a lifting assembly is installed at the bottom of the inner wall of the cylinder 2 to cooperate with the filter basket 26. The lifting assembly includes a guide rail 48 installed at the bottom of the inner wall of the cylinder 2, a housing 42 installed at the center of the bottom of the inner wall of the cylinder 2, a lifting rod 43 that slides and elastically cooperates with the housing 42, and a lifting plate 45 that rotatably cooperates with the lifting rod 43. The lifting plate 45 cooperates with the filter basket 26, and multiple limiting grooves 46 are provided on the lifting plate 45. The limiting grooves 46 and the guide rail 48 both cooperate with the connecting leg 52. A rotating ball 53 is installed at the bottom of the connecting leg 52. The structure of the rotating ball 53 is the same as that of the universal ball in the prior art. It is used to slide in the guide rail 48. The guide rail 48 is an annular guide rail. A second spring 44 is also installed in the housing 42. The second spring 44 is installed between the lower side of the lifting rod 43 and the cylinder 2. A connecting block 47 for connecting with the bottom of the cylinder 2 is also installed on the lower side of the guide rail 48.

[0041] When the filter basket 26 moves down, the lifting plate 45 is squeezed by the lifting component, causing the second spring 44 to contract. When the basket cover 14 rises, the second spring 44 pushes the filter basket 26 and the dried lithium carbonate inside it out of the cylinder 2. After being pushed out, it is not only convenient for the staff to take out the dried lithium carbonate inside the filter basket 26, but the lifting plate 45 can also prevent excessive heat loss from the inner cavity of the cylinder 2, thus playing an energy-saving role.

[0042] like Figures 1-2 and Figures 8-9 As shown, in this embodiment, an L-shaped support block 3 is installed on one side of the fixing frame 1, and a hot air blower 4 is installed on one side of the L-shaped support block 3. The output end of the hot air blower 4 is connected to the cylinder 2 by an air duct 5. A liquid inlet pipe 51 is provided at the top of one side of the cylinder 2 in this embodiment. A liquid outlet pipe 49 is provided at the bottom of one side of the cylinder 2, and a filter 50 is connected to the outlet end of the liquid outlet pipe 49. By starting the hot air blower 4, the hot air blower 4 heats the inside of the cylinder 2 through the air duct 5, thereby raising the temperature inside the cylinder 2 and achieving the purpose of drying lithium carbonate.

[0043] One application of this embodiment is as follows: In use, the precipitated crude lithium carbonate is first placed into the filter basket 26. The placeholder block 29 inside the filter basket 26 prevents excessive lithium carbonate from being added, which could lead to poor centrifugation efficiency. The filter basket 26 containing lithium carbonate is then placed inside the cylinder 2, and the connecting leg 52 is inserted into the lifting assembly, supporting the filter basket 26. Then, the pressing assembly is activated, causing the basket cover 14 to move steadily downwards until it covers the upper end of the filter basket 26. The support from the lower lifting assembly, combined with the pressure from the upper basket cover 14, effectively clamps and limits the filter basket 26. The function of the cover 14 ensures the stability of the filter basket 26. Simultaneously, during the stable downward movement of the cover 14, the stirring component inside the cover 14 stirs the lithium carbonate in the filter basket 26, balancing its weight and preventing shaking and damage during centrifugation. The cover 14's compression of the filter basket 26 also causes the protrusion 54 on the connecting leg 52 to retract the placeholder block 29 into the filter basket 26, preventing the placeholder block 29 from affecting the centrifugation effect. Then, the cleaning solution is injected into the cylinder 2 through the inlet pipe 51. After the cleaning solution is injected, the motor 12 is started. The motor 12 rotates the cover 14 via the rotating rod 13, thereby causing the cover 14 to move the filter basket. The filter basket 26 rotates, causing the cleaning liquid to rotate as well. This agitates and washes the crude lithium carbonate inside the filter basket 26. Under the flow of the cleaning liquid, the mother liquor and soluble impurities adsorbed on the surface of the crude lithium carbonate are rinsed off. After washing, the cleaning liquid inside the cylinder 2 is discharged through the drain pipe 49. The discharged cleaning liquid will enter the filter 50 to avoid contamination. After the cleaning liquid is completely discharged, the motor 12 continues to run, driving the filter basket 26 and the washed lithium carbonate inside to continue rotating. Under centrifugal force, excess liquid on the lithium carbonate is thrown off. At the same time, the hot air blower 4 is started, and the hot air blower 4 heats the inside of the cylinder 2 through the air duct 5, thereby raising the temperature inside the cylinder 2. The process is as follows: After drying, the pressure assembly is activated. The cylinder 7 is activated, and the piston rod 9 drives the concave block 10 to rise or fall. The rise or fall of the concave block 10 drives the cylinder cover 11 to rise or fall. The rise or fall of the cylinder cover 11 drives the motor 12 to rise or fall. The rise or fall of the motor 12 drives the basket cover 14 to rise or fall. The basket cover 14 moves upward away from the filter basket 26. Finally, under the action of the second spring 44, the filter basket 26 and the dried lithium carbonate inside it are pushed out of the cylinder 2. After being pushed out, it is not only convenient for the staff to take out the dried lithium carbonate inside the filter basket 26, but the lifting assembly can also prevent excessive heat loss in the inner cavity of the cylinder 2, thus playing an energy-saving role.

Anyone should understand that structural changes made under the guidance of this invention, and any technical solutions that are the same as or similar to this invention, fall within the protection scope of this invention. Technical aspects, shapes, and structures not described in detail in this invention are all publicly known technologies.
