Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium carbonate technology, specifically to a dynamically concentrated lithium carbonate refining storage tank. Background Technology
[0002] Lithium carbonate (Li₂CO₃) is an important inorganic lithium salt, a white powder at room temperature, slightly soluble in water, and weakly alkaline. As a core raw material in the lithium battery industry chain, it is mainly used to prepare cathode materials for lithium-ion batteries (such as lithium cobalt oxide, lithium iron phosphate, and ternary materials), and is also a key additive in glass ceramics, rare earth smelting, and pharmaceuticals. Its purity grade (industrial grade / battery grade) directly affects the performance of downstream products. Battery-grade lithium carbonate (purity ≥ 99.5%) has extremely strict requirements for impurity control and is the cornerstone of ensuring battery safety and energy density.
[0003] Dynamic concentration-adjustable lithium carbonate refining storage tanks are a technology that monitors and actively adjusts the lithium ion concentration in the solution (or slurry) in real time during the lithium carbonate refining process. The purpose is to maintain the optimal concentration range required for the reaction or crystallization, thereby improving product purity, crystal morphology, and process efficiency. However, lithium carbonate solutions may produce precipitates during the reaction during storage, which leads to a decrease in the overall concentration of the solution and affects the usability when it is retrieved. Therefore, we propose a dynamic concentration-adjustable lithium carbonate refining storage tank. Utility Model Content

[0026] Please see Figures 1-6 This utility model provides a technical solution:
[0027] A dynamically concentrated lithium carbonate refining storage tank includes: a storage tank 1, with a connecting cover 2 fixedly connected to the top of the storage tank 1. The tank is characterized by: multiple electric valves 3 fixedly connected to the back of the storage tank 1; a liquid pump 4 is provided on one side of each electric valve 3; an infusion pipe 5 is fixedly connected to the other end of each electric valve 3; a pure water tank 6 is fixedly connected to the bottom of one infusion pipe 5; a concentrated lithium liquid tank 7 is fixedly connected to the bottom of the storage tank 1; a supporting base plate 8 is fixedly connected to the bottom of the storage tank 1, the position of which matches the pure water tank 6 and the concentrated lithium liquid tank 7; a control console 9 is fixedly connected to one side of the storage tank 1; a concentration sensor 10 is provided on one side of the control console 9; a stirring assembly 11 is provided on the inner wall of the storage tank 1; an anti-sedimentation assembly 12 is fixedly connected to the surface of the stirring assembly 11; and multiple supporting legs 13 are fixedly connected to the bottom of the storage tank 1.
[0028] In this embodiment, the storage tank 1 provides storage space for lithium carbonate solution, and the connecting cap 2 helps to seal the inside of the storage tank 1. The user can use the control console 9 to control the opening of the electric valve 3 through the electrical connection of the entire device. When needed, the liquid pump 4 can be used to extract the liquid from the pure water tank 6 or the concentrated lithium solution tank 7 and input it into the storage tank 1 through the infusion pipe 5 to adjust the concentration of the lithium carbonate solution inside the storage tank 1. The supporting base plate 8 can support the pure water tank 6 and the concentrated lithium solution tank 7 from the bottom to improve the stability of the device. The concentration sensor 10 can monitor the concentration inside the storage tank 1 at any time and transmit it to the control console 9 for the user to observe. The stirring assembly 11 can be continuously started to keep the lithium carbonate solution inside the storage tank 1 flowing to prevent precipitation from affecting the concentration. The anti-precipitation assembly 12 can work with the stirring assembly 11 to further prevent precipitation and improve the storage effect of the device.
[0029] The stirring assembly 11 includes a motor stabilizing plate 1101, a drive motor 1102, a rotating base 1103, a rotating central shaft 1104, staggered stirring rods 1105, a limiting plate 1106, a connecting plate 1107, and a cleaning brush 1108. The motor stabilizing plate 1101 is fixedly connected to the bottom of the storage tank 1, the drive motor 1102 is located on one side of the motor stabilizing plate 1101, and the rotating base 1103 is located at the bottom of the inner wall of the storage tank 1.
[0030] In this embodiment, the stirring assembly 11 can use the structure of the drive motor 1102 to drive the rotating central shaft 1104 to rotate, providing a rotational basis for the rotation of the rotating central shaft 1104. The rotating base 1103 provides a stable base for the rotation of the rotating central shaft 1104. The motor stabilizing plate 1101 can help the drive motor 1102 to remain stable on one side during use, preventing the drive motor 1102 from rotating on its own during use.
[0031] A rotating central shaft 1104 is located on top of a drive motor 1102, multiple staggered stirring rods 1105 are fixedly connected to the surface of the rotating central shaft 1104, and a limiting plate 1106 is fixedly connected to the top of the rotating central shaft 1104.
[0032] In this embodiment, the rotating central shaft 1104 drives the staggered stirring rods 1105, which are fixedly installed in an alternating manner, to continuously stir inside the storage tank 1, maintaining the flow of the lithium carbonate liquid inside and preventing precipitation. The limiting plate 1106 can help reinforce the installation of the rotating central shaft 1104, thereby further improving the overall stability of the device.
[0033] Multiple connecting plates 1107 are fixedly connected to the bottom surface of the rotating central shaft 1104, and multiple cleaning brushes 1108 are fixedly connected to the bottom of the connecting plates 1107. The size of the cleaning brushes 1108 matches the distance of the anti-settling component 12.
[0034] In this embodiment, the connecting plate 1107 can be fixed on both sides of the rotating central shaft 1104 so that it rotates with the rotating central shaft 1104, driving the cleaning brush 1108 to continuously clean the top of the anti-precipitation component 12, thereby preventing the accumulation of lithium carbonate precipitate and further improving the anti-precipitation effect of the device.
[0035] The anti-sedimentation component 12 includes a connecting base plate 1201, fixing nails 1202, mounting holes 1203 and cleaning columns 1204. The connecting base plate 1201 is disposed at the bottom of the inner wall of the storage tank 1, and multiple fixing nails 1202 are fixedly connected to the bottom of the connecting base plate 1201.
[0036] In this embodiment, the anti-sedimentation component 12 can be fixed to the bottom of the inner wall of the storage tank 1 by using the connecting base plate 1201 and the fixing nails 1202, thereby providing an overall fixed foundation for the anti-sedimentation component 12.
[0037] Mounting holes 1203 are formed on the inner wall of the connecting base plate 1201. The size of the mounting holes 1203 matches the size of the rotating base 1103. Multiple cleaning columns 1204 are fixedly connected to the top of the connecting base plate 1201.
[0038] In this embodiment, the mounting hole 1203 can fix the anti-precipitation component 12 to the surface of the rotating base 1103. At the same time, the cleaning column 1204 is used to perform secondary cleaning of the lithium carbonate precipitate attached to the bottom of the cleaning brush 1108 during the movement of the stirring component 11, so as to prevent the lithium carbonate precipitate from adhering to the inside of the cleaning brush 1108 and affecting the concentration of the lithium carbonate solution inside the storage tank 1.
[0039] Working Principle: This device provides a sealed space for storing lithium carbonate solution through storage tank 1. Connecting cap 2 allows for easy pouring of lithium carbonate solution into storage tank 1 and sealing. Electric valve 3 allows the user to operate via control console 9 to open it at any time based on information from concentration sensor 10. Liquid from pure water tank 6 or concentrated lithium solution tank 7 is drawn into the storage liquid in storage tank 1 through infusion tube 5 using liquid pump 4 to adjust the concentration. This completes the basic concentration adjustment function, allowing for convenient access to lithium carbonate solution of appropriate concentration at any time. Support base plate 8 can be combined with support legs 13 and the bottom of storage tank 1 to support pure water tank 6 and concentrated lithium solution tank 7, improving the overall stability of the device. At the same time, stirring component 11 can be continuously turned on to maintain the fluidity of the liquid inside storage tank 1, preventing precipitation of lithium carbonate solution in a static state from affecting the overall concentration of the liquid inside. In addition, anti-precipitation component 12 can further dissolve the solution after precipitation occurs, improving the overall storage effect of the device. Support legs 13 can support the entire device from the bottom, improving the overall stability of the device.
