Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, specifically a reaction vessel for nickel carbonate production. Background Technology
[0002] Nickel carbonate (NiCO3) is an important nickel compound widely used in battery manufacturing, catalysts, pigments, and chemical synthesis. As nickel is a key component in nickel-metal hydride and lithium-ion batteries, it is particularly crucial in the battery industry. A reaction vessel is a container specifically designed for chemical reactions, providing suitable reaction conditions (such as temperature, pressure, and stirring) to promote the reaction. In the production of nickel carbonate, the reaction vessel effectively stirs and mixes the raw materials, ensuring that the reactants react under uniform conditions, thereby improving reaction efficiency and product quality.
[0003] An investigation revealed that a Chinese utility model discloses a reaction vessel for nickel carbonate production (publication number: CN221847136U), comprising a reaction vessel body, an installation frame at the top of the inner cavity of the reaction vessel body, a filter screen inside the installation frame, a stirring roller rotatably mounted on the bottom wall of the inner cavity of the reaction vessel body, the top end of the stirring roller penetrating the filter screen and being rotatably connected to the filter screen, and a first motor fixedly mounted at the bottom of the reaction vessel body, the output end of the first motor being drivenly connected to the stirring roller.
[0004] Although the aforementioned patent can filter and crush the input raw materials through a filter screen and a stirring roller, and crush some larger particles to make the stirring more uniform, and the air blowing mechanism can evenly disperse the filtered and crushed raw materials into the reactor body to make the mixing more uniform, reduce the mixing time of the raw materials and improve the working efficiency of the stirring, the distance between the stirring roller and the filter screen is not adjustable, making it difficult to control the rolling pressure. Excessive rolling may damage the crystal structure of nickel carbonate, resulting in reduced activity and affecting its chemical reaction activity and catalytic efficiency.

[0027] 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.
[0028] This utility model provides a reaction vessel for nickel carbonate production, such as... Figures 1-5 As shown, a reaction vessel for nickel carbonate production includes a reaction vessel body 1, a stirring assembly fixedly installed in the middle of the lower surface of the reaction vessel body 1, a vibration assembly fixedly connected inside the reaction vessel body 1, and a rolling assembly fixedly connected in the middle of the upper surface of the reaction vessel body 1.
[0029] The rolling assembly includes a cylinder 2. The bottom end of the cylinder 2 is fixedly connected to the middle of the upper surface of the reactor body 1. The top end of the cylinder 2 is fixedly connected to a connecting frame 3. The bottom end of the connecting frame 3 is fixedly connected to a pressure rod 4. When the cylinder 2 is started, the pressure rod 4 moves up and down through the connecting frame 3, thereby controlling the distance between the pressure rod 4 and the sieve plate 8. This allows for adjustment of the rolling pressure exerted by the pressure rod 4 on nickel carbonate, preventing excessive rolling from damaging the crystal structure of nickel carbonate, which would reduce its activity and affect its chemical reaction activity and catalytic efficiency.
[0030] The mixing assembly includes a motor 5, the upper surface of which is fixedly mounted in the middle of the lower surface of the reactor body 1. A rotating rod 6 is fixedly connected to the output end of the motor 5. A stirring blade 7 is fixedly connected to the middle of the outer surface of the rotating rod 6. A sieve plate 8 is slidably connected to the outer surface of the rotating rod 6 above the stirring blade 7. When the motor 5 is started by an external power source, the rotating rod 6 drives the stirring blade 7 to rotate, which can stir the substances inside the reactor body 1 and drive the sieve plate 8 to rotate, so as to receive nickel carbonate and make the nickel carbonate enter the sieve plate 8 evenly. This facilitates the uniform rolling of the sieve plate 8 by the pressure rod 4. At the same time, after rolling, the sieve plate 8 will vibrate during continuous rotation, which facilitates the uniform entry of the nickel carbonate on the upper surface of the sieve plate 8 into the reactor body 1 and avoids clogging of the sieve plate 8, thereby effectively ensuring the uniformity of the mixing and improving the mixing efficiency.
[0031] The vibration assembly includes a fixed ring 9, the outer surface of which is fixedly connected to the inner wall of the reactor body 1. A groove is provided on the upper surface of the fixed ring 9, and a heating plate 10 is fixedly connected inside the groove. A memory spring 11 is fixedly connected to the upper surface of the heating plate 10, and a limit ring 12 is fixedly connected to the top of the memory spring 11. When the heating plate 10 is activated to heat the memory spring 11, the memory spring 11 can be in a retractable state so that when the rotating rod 6 drives the sieve plate 8 to rotate, the sieve plate 8 can vibrate up and down. Subsequently, turning off the heating plate 10 can restore the memory spring 11 to a normal temperature state so that it is in a fixed state, fixing the position of the sieve plate 8, which facilitates the pressure rod 4 to roll the nickel carbonate above it.
[0032] A limiting groove is provided on the outer surface of the rotating rod 6 at the connection point of the screen plate 8. A limiting block 13 adapted to the limiting groove is provided on the inner wall of the screen plate 8. The limiting block 13 is slidably connected inside the limiting groove, so that the screen plate 8 can rotate with the rotating rod 6 and can move up and down.
[0033] A feed inlet is provided on one side of the upper surface of the reactor body 1, and a feed pipe 14 is fixedly connected to the edge of the feed inlet. Nickel carbonate can be added to the inside of the reactor body 1 through the feed pipe 14.
[0034] A discharge port is provided on one side of the lower surface of the reactor body 1, and a discharge pipe 15 is fixedly connected to the edge of the discharge port, so that the reacted nickel carbonate can be discharged through the discharge pipe 15.
[0035] A support leg 16 is fixedly connected to the bottom of the outer surface of the reactor body 1. A base plate 17 is fixedly connected to the bottom of the support leg 16. The support leg 16 supports the reactor body 1 and leaves space below it to facilitate the installation of the motor 5 and the discharge pipe 15. The base plate 17 can increase the contact area between the support leg 16 and the ground, thereby improving the stability of the device.
[0036] Working steps: First, nickel carbonate is added into the reactor body 1 through the feed pipe 14. At the same time, the external power supply starts the motor 5, which drives the stirring blade 7 to rotate via the rotating rod 6. This stirs the material inside the reactor body 1 and drives the sieve plate 8 to rotate, so as to receive the nickel carbonate evenly. Next, the cylinder 2 is started, which drives the pressure rod 4 to move up and down via the connecting frame 3. This controls the distance between the pressure rod 4 and the sieve plate 8. During the rotation of the sieve plate 8, the nickel carbonate is rolled. After the rolling is completed, the heating plate 10 is started to heat the memory spring 11, which puts the memory spring 11 into a retractable state. During the continuous rotation of the sieve plate 8, it will vibrate, which makes it easier for the nickel carbonate on the upper surface of the sieve plate 8 to enter the reactor body 1 evenly. Finally, the reacted nickel carbonate can be discharged through the discharge pipe 15.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
