Description

Technical Field

[0001] This utility model belongs to the technical field of lithium carbonate processing equipment, specifically a washing device for lithium carbonate production. Background Technology

[0002] Lithium carbonate is an important inorganic compound widely used in new energy, materials science, medicine and other fields. In the production process of lithium carbonate, the crude lithium carbonate needs to be washed to remove the mother liquor and various soluble impurities adsorbed on the surface of the lithium carbonate. Therefore, a corresponding washing device is required.

[0003] A search revealed a washing device for lithium carbonate production, published under publication number CN220697643U. The device addresses the issue that, due to the weight of the crude lithium carbonate itself, it tends to precipitate onto the bottom wall of the stirring device, resulting in poor washing performance. The solution involves a crankshaft, moving rods, moving blocks, and actuating plates. A drive motor rotates the crankshaft, causing the stirring paddles to rotate and agitate the material and washing liquid in the washing tank. Simultaneously, as the crankshaft rotates, the moving rods at each crank point pull the corresponding moving blocks up and down, thus agitating the precipitated material in the washing tank as the blocks move downwards. The material is impacted, causing it to mix in the washing liquid. The cooperation between the moving blocks and the stirring paddles can complete the mixing and agitation of the material and the washing liquid in the washing tank. This has the advantage of reducing material sedimentation in the washing tank and ensuring the quality of lithium carbonate washing. However, in actual use, there are still shortcomings. Because lithium carbonate particles are prone to forming agglomerates during the crystallization process, the surface of the crude lithium carbonate is uneven, which prevents the washing liquid from fully contacting the crude lithium carbonate. Consequently, the micropores and cracks of the crude lithium carbonate cannot be effectively washed, affecting the washing effect. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a washing device for lithium carbonate production, which has the advantage of better washing effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a washing device for lithium carbonate production, comprising a washing tank, a base movably connected to the bottom of the washing tank, a partition fixedly sleeved on the top of the inner surface of the base, the top of the partition movably connected to the bottom of the washing tank, U-shaped frames movably sleeved inside the left and right ends of the partition, the top of the U-shaped frames fixedly connected to the bottom of the washing tank, a vertical rod movably sleeved inside the middle of the partition, the top of the vertical rod fixedly connected to the bottom of the washing tank, a fixed shaft fixedly sleeved inside the bottom of the vertical rod, a wheel movably sleeved on the outer surface of the fixed shaft, the outer surface of the wheel movably sleeved to the inner surface of the vertical rod, an inclined block movably connected to the lower right of the outer surface of the wheel, a rectangular seat movably sleeved at the bottom of the inclined block, the bottom of the rectangular seat movably sleeved to the right side of the bottom of the inner surface of the base, a support plate fixedly installed on the right side of the top center of the rectangular seat, a pneumatic cylinder fixedly sleeved inside the support plate, the left end of the pneumatic cylinder fixedly connected to the right end of the inclined block.

The bottom end of the rectangular block is movably connected to the bottom of the inner surface of the base.

[0007] As a preferred embodiment of this utility model, a servo motor is fixedly sleeved on the rear part of the bottom left side of the inner surface of the base, and a threaded rod is fixedly sleeved on the other end of the output shaft of the servo motor.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5As shown, this utility model provides a washing device for lithium carbonate production, including a washing tank 1. A base 2 is movably connected to the bottom of the washing tank 1. A partition 3 is fixedly sleeved on the top of the inner surface of the base 2. The top of the partition 3 is movably connected to the bottom of the washing tank 1. U-shaped frames 4 are movably sleeved inside the left and right ends of the partition 3, and the top of the U-shaped frames 4 is fixedly connected to the bottom of the washing tank 1. A vertical rod 5 is movably sleeved inside the middle of the partition 3, and the top of the vertical rod 5 is fixedly connected to the bottom of the washing tank 1. A fixed shaft 6 is fixedly sleeved inside the bottom of the vertical rod 5. A wheel 7 is movably sleeved on the outer surface of the fixed shaft 6. The outer surface of the wheel 7 is movably sleeved on the inner surface of the vertical rod 5. An inclined block 8 is movably connected to the lower right of the outer surface of the wheel 7. A rectangular seat 9 is movably sleeved at the bottom of the inclined block 8. The bottom of the rectangular seat 9 is movably sleeved on the right side of the bottom of the inner surface of the base 2. Next, a support plate 10 is fixedly installed on the right side of the top center of the rectangular base 9. A pneumatic cylinder 11 is fixedly sleeved inside the support plate 10. The left end of the pneumatic cylinder 11 is fixedly connected to the right end of the inclined block 8. When the pneumatic cylinder 11 is activated, the inclined block 8 will move along the top of the rectangular base 9, thereby generating a thrust on the wheel 7. This pushes the wheel 7 to move upward along the vertical rod 5 through the fixed shaft 6, causing the washing tank 1 to move together with the vertical rod 5. When the inclined block 8 stops pushing the wheel 7, the washing tank 1, the vertical rod 5, and the wheel 7 will return to their original positions under the action of gravity. This cycle repeats, thereby achieving the vibration of the washing tank 1 and improving the washing effect. At the same time, the cooperation between the partition plate 3 and the U-shaped frame 4 can also limit the vibration of the washing tank 1, thereby ensuring the stability of the vibration of the washing tank 1.

[0022] The rectangular base 9 has a diagonal rod 12 hinged to the middle of its left end, and a rectangular block 13 hinged to the other end of the diagonal rod 12. The bottom end of the rectangular block 13 is movably connected to the bottom of the inner surface of the base 2. When the rectangular block 13 moves along the bottom of the inner surface of the base 2, since the left and right ends of the diagonal rod 12 are hinged to the rectangular block 13 and the rectangular base 9 respectively, the left end of the diagonal rod 12 will move along with the rectangular block 13. This causes the other end of the diagonal rod 12 to exert a pushing force on the rectangular base 9, pushing the rectangular base 9 to move. This allows the adjustment of the distance between the diagonal block 8 and the wheel 7 to be achieved.

[0023] A servo motor 14 is fixedly sleeved on the rear part of the bottom left side of the inner surface of the base 2. A threaded rod 15 is fixedly sleeved on the other end of the output shaft of the servo motor 14. The rear side of the outer surface of the threaded rod 15 is threadedly sleeved with the inner surface of the middle part of the rectangular block 13. When the servo motor 14 is started, the threaded rod 15 will rotate, thereby causing the rectangular block 13, which is threadedly sleeved with the threaded rod 15, to move along with the left end of the inclined rod 12. At the same time, a support block is provided on the front side of the outer surface of the threaded rod 15, so as to ensure the stability of the rotation of the threaded rod 15.

[0024] The washing tank 1 has a drive motor 16 fixedly installed in the middle of the left end. The other end of the output shaft of the drive motor 16 is fixedly sleeved with a crank 17. The right end of the crank 17 passes through the washing tank 1 and extends to the right side of the washing tank 1. The left and right sides of the outer surface of the crank 17 are respectively fixedly sleeved with stirring paddles 18. When the drive motor 16 is started, the crank 17 will drive the stirring paddles 18 to rotate, thereby stirring and washing the material and washing liquid inside the washing tank 1 through the stirring paddles 18, preventing the material from settling at the bottom of the washing tank 1. At the same time, the middle end of the crank 17 is a U-shaped crank.

[0025] The crank 17 has a circular sleeve 19 movably fitted in the middle of its outer surface, and a moving rod 20 is fixedly installed at the bottom of the circular sleeve 19. Both the outer surface of the crank 17 and the inner surface of the circular sleeve 19 are smooth, which ensures that the crank of the crank 17 can rotate on the inner surface of the circular sleeve 19, thereby ensuring that the crank 17 can rotate normally under the action of the drive motor 16.

[0026] The bottom end of the moving rod 20 is hinged to a moving block 21, and the bottom end of the moving block 21 is fixedly installed with a deflector plate 22. The outer surface of the deflector plate 22 is movably sleeved with the inner surface of the washing tank 1. When the crank 17 rotates, the sleeve 19 and the top end of the moving rod 20 will rotate together, thereby causing the bottom end of the moving rod 20 to generate a pulling force on the moving block 21, pulling the moving block 21 and the deflector plate 22 to move in the vertical direction. In this way, the up and down movement of the deflector plate 22 can impact the sediment in the washing tank, making it mix in the washing liquid.

[0027] The four corners of the outer surface of the movable block 21 are movably connected with guide bars 23. There are four guide bars 23, and the bottom ends of the four guide bars 23 are fixedly connected to the bottom of the inner surface of the washing tank 1. The length of the guide bars 23 is greater than the distance that the movable block 21 can move up and down. By setting the four guide bars 23, the movable block 21 can be limited, thereby ensuring that the movable block 21, along with the actuating plate 22, can move up and down in the vertical direction.

[0028] Working principle and usage process of this utility model:

[0029] In use, the operator first starts the drive motor 16, causing the crank 17 to drive the agitator 18 to rotate. This causes the sleeve 19 and the moving rod 20 to exert a pulling force on the moving block 21, pulling the moving block 21 and the actuating plate 22 to move up and down along the guide bar 23. At the same time, the operator starts the pneumatic cylinder 11, causing the inclined surface of the inclined block 8 to exert a pushing force on the circular wheel 7, pushing the circular wheel 7 through the fixed shaft 6 and the vertical rod 5 to move the washing tank 1 vertically upward. When the inclined block 8 stops pushing the circular wheel 7, the washing tank 1 will return to its original position under the action of gravity. This cycle is repeated to achieve the vibration of the washing tank 1. Through vibration, the washing liquid is directly applied to the micropores and cracks of the crude lithium carbonate, thereby further improving the washing effect.

[0030] Before the washing tank 1 vibrates, the operator starts the servo motor 14, causing the threaded rod 15 to rotate. This causes the rectangular block 13, which is threaded onto the outer surface of the threaded rod 15, to move along the inner surface of the bottom of the base 2, carrying one end of the inclined rod 12. This causes the other end of the inclined rod 12 to exert a thrust on the rectangular seat 9, pushing the rectangular seat 9 to move along with the inclined block 8 and the pneumatic cylinder 11. By adjusting the distance between the inclined block 8 and the wheel 7, the amplitude of the washing tank 1 can be adjusted, allowing the operator to adjust the vibration amplitude according to the actual situation of the material.
