Description

Technical Field

[0002] Cobalt acetate, also known as cobalt acetic acid, is an organic compound. Its production process uses cobalt oxide as raw material, which reacts with nitric acid to prepare cobalt nitrate solution. Then, it reacts with soda ash solution to generate cobalt carbonate precipitate. After washing and separation, acetic acid is added for acidification. The reaction solution is filtered, the pH value is adjusted, and it is concentrated to obtain cobalt acetate-acetic acid solution for recrystallization. Finally, it is centrifuged to obtain the finished cobalt acetate product.

[0003] In the production process, metallic cobalt is first used as the starting material.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-3As shown, a reactor for cobalt acetate production includes a reaction vessel 1. Several support legs 8 are fixedly distributed at the bottom of the reaction vessel 1. A feed cylinder 6 is fixedly connected to the top of the reaction vessel 1 for feeding. A discharge cylinder 7 is fixedly connected to the side of the reaction vessel 1 for discharging. The reactor also includes a grinding structure, which includes a grinding box 2 fixed to the side of the reaction vessel 1. A grinding roller 24 is rotatably connected to the top of the reaction vessel 1. The grinding roller 24 rotates to grind the cobalt on the top of the filter plate 21. A filter plate 21 for cobalt powder filtration is also provided inside the grinding box 2. The grinding roller 24 is located above the filter plate 21. A feed pipe 26 connects the bottom of the grinding box 2 to the side of the reaction vessel 1. A feed hopper 22 for cobalt feeding is connected to the upper surface of the grinding box 2. The top of the hopper 22 is covered with a cover plate 23 to prevent dust from flying. The top of the reactor 1 is rotatably connected to a stirring roller 5. A speed reduction structure is also provided between the outside of the stirring roller 5 and the reactor 1. Several stirring blades 52 for stirring are distributed on the side of the stirring roller 5 inside the reactor 1. The top of the reactor 1 is provided with a drive structure to drive the stirring roller 5 to rotate. A linkage structure is also provided between the stirring roller 5 and the grinding roller 24. During the rotation of the stirring roller 5, the grinding roller 24 can be driven to rotate by the synchronous belt 31 to grind the solid raw material cobalt on the filter plate 21. The ground powdered raw material cobalt enters the reactor 1 through the feed pipe 26, which facilitates the subsequent mixing of raw material cobalt and liquid dilute acetic acid, improving the stirring efficiency. The liquid after the reaction flows out through the discharge pipe 7.

[0028] In some specific implementation plans, such as Figure 2 As shown, in order to enhance the stability of the rotation of the grinding roller 24, a limiting sleeve 25 is provided between the grinding box 2 and the grinding roller 24. The height of the limiting sleeve 25 is higher than the height of the top plate of the grinding box 2. The limiting sleeve 25 is fixedly connected to the top of the grinding box 2. The grinding roller 24 is rotatably connected inside the limiting sleeve 25 to prevent the grinding roller 24 from tilting during rotation and affecting the grinding effect.

[0029] In some specific implementations, in order to facilitate the rotation of the stirring roller 5, the driving structure includes a motor 51. A fixed frame 45 is fixedly installed on the top of the reactor 1, and the motor 51 is fixed on the fixed frame 45. The driving end of the motor 51 is connected to the top of the stirring roller 5. Starting the motor 51 can drive the stirring roller 5 to rotate.

[0030] In some specific implementations, in order to facilitate the rotation of the grinding roller 24 during the rotation of the stirring roller 5, the linkage structure includes a driven synchronous wheel 3 and a driving synchronous wheel 32. The driven synchronous wheel 3 is fixed on the top of the grinding roller 24, and the driving synchronous wheel 32 is fixed on the outside of the stirring roller 5. A synchronous belt 31 is fitted on the outside of the driving synchronous wheel 32 and the driven synchronous wheel 3. During the rotation of the stirring roller 5 and the driving synchronous wheel 32, the driven synchronous wheel 3 can drive the grinding roller 24 to rotate due to the action of the synchronous belt 31.

[0031] In some specific implementation plans, such as Figure 3 As shown, to facilitate the deceleration of the fixed cylinder 41, the deceleration structure includes an internal gear ring 4, a drive gear 42, and a rotating shaft 44. The drive gear 42 is fixed to the outside of the stirring roller 5, and the internal gear ring 4 is fixed to the upper surface of the disc 40 and is integrally formed. The disc 40 has a through hole for the stirring roller 5 to pass through. The fixed cylinder 41 is located at the bottom of the disc 40, aligned with the through hole. The fixed cylinder 41 is rotatably connected to the top of the reactor 1 and extends to its inner side. The rotating shaft 44 is rotatably connected to the fixed frame 45. A driven gear 43 is fixed at the bottom of the rotating shaft 44. One side of the driven gear 43 is meshed with the driving gear 42, and the other side is rotatably connected to the internal gear ring 4. The motor 51 drives the driving gear 42 on the stirring roller 5 to rotate. The driven gear 43 meshes with the driving gear 42 and the internal gear ring 4 respectively. By utilizing the cooperation of the driving gear 42, the driven gear 43 and the internal gear ring 4, the rotation speed of the fixed cylinder 41 is reduced. The deceleration structure drives the scraper 54 to scrape the inner wall of the reactor 1, thereby reducing the wear rate of the scraper 54.

[0032] In some specific implementations, in order to facilitate the scraping of the inner wall of the reactor 1 by the rotating scraper 54 of the fixed cylinder 41, a scraper 54 is fixedly provided on the side of the fixed cylinder 41. The scraper 54 is in contact with the inner wall of the reactor 1. A reinforcing rod 55 is provided between the scraper 54 and the lower end of the fixed cylinder 41 to strengthen the connection strength of the scraper 54. During the rotation of the fixed cylinder 41, the scraper 54 scrapes the inner wall of the reactor 1.

[0033] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:

[0034] In operation, solid cobalt is first placed in the grinding box 2, and liquid dilute acetic acid is fed into the reactor 1 through the feed cylinder 6. Then, the motor 51 is started to drive the stirring roller 5 to rotate, which in turn drives the driven gear 43 to rotate, and in turn drives the internal gear ring 4 meshing with the driven gear 43 to rotate. The stirring roller 5 drives the stirring blade 52 to rotate, which improves the stirring effect. At the same time, the stirring roller 5 drives the scraper 54 to decelerate and scrape off the cobalt powder adhering to the inner wall of the reactor 1. Together with the stirring blade 52, the solid cobalt and liquid dilute acetic acid are fully mixed, reducing material waste. During the rotation of the stirring roller 5, the grinding roller 24 can be driven to rotate through the synchronous belt 31 to grind the solid cobalt on the filter plate 21. The ground cobalt powder enters the reactor 1 through the feed pipe 26, which facilitates the subsequent mixing of cobalt and liquid dilute acetic acid, improving the stirring efficiency. The reacted liquid flows out through the discharge cylinder 7.

[0035] The foregoing has described several embodiments of this utility model in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
