Abstract

[0002] The agitation tank is an indispensable key piece of equipment in the lithium carbonate production process, widely used in the cleaning of various minerals. This equipment uses the rotation of an agitator impeller to ensure thorough contact and mixing of the material with the cleaning solution. Through mechanical force, impurities and contaminants on the material surface are removed, ensuring the quality of subsequent processing. During the cleaning process, appropriate chemical cleaning agents are sometimes added to the cleaning solution. These cleaning agents can chemically react with the dirt on the material surface, decomposing and dissolving the dirt, thereby improving the cleaning effect.
[0003] Currently, in the lithium carbonate production process, lithium ore contains a large amount of fixed impurities. After prolonged operation, these impurities tend to accumulate in large quantities at the bottom of the mixing tank, affecting not only the normal flow of raw materials but also potentially reducing the efficiency of the mixing device and even causing equipment damage. Therefore, effectively removing these fixed impurities and maintaining the good working condition of the mixing tank has become an urgent technical problem to be solved. Utility Model Content

[0022] The following will be combined with the appendix Figure 1 -Appendix Figure 3The technical solutions in the embodiments of the present invention are clearly and completely described herein. The described embodiments are only possible technical implementations of the present invention and not all possible implementations. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of the present invention without creative effort, and these embodiments are also within the protection scope of the present invention.
[0023] The inventors of this application have discovered that in the current lithium carbonate production process, due to the presence of numerous fixed impurities in lithium ore, these impurities tend to accumulate in large quantities at the bottom of the mixing tank after prolonged operation. This not only affects the normal flow of raw materials but may also lead to a decrease in the efficiency of the mixing device, or even damage to the equipment. Therefore, this application discloses a mixing tank for lithium carbonate production, mainly employing the following solution:
[0024] Example 1
[0025] This application discloses a stirring tank for lithium carbonate production. (Refer to...) Figure 1 The system includes a tank body 1, with a raw material inlet 11 and a cleaning liquid inlet 12 at the top and a raw material outlet 13 at the bottom. The tank body 1 is equipped with a stirring device for stirring materials. A guide section 14 is provided near the bottom of the tank body 1 to guide fixed impurities to be discharged from the raw material outlet 13, thereby effectively removing fixed impurities and maintaining the stirring tank in good working condition.
[0026] Reference Figure 1 The mixing device includes a mixing rod 15, a mixing impeller 16, and a motor 17. The mixing rod 15 is rotatably inserted into the tank 1, and its axis is vertical. The mixing impeller 16 is fixedly mounted on the mixing rod 15. The motor 17 is fixedly mounted on the top of the tank 1, and its output shaft is coaxially and fixedly connected to the mixing rod 15 to drive its rotation. The mixing rod 15 can be made of stainless steel to prevent corrosion and extend its service life; alternatively, it can be made of carbon steel, suitable for lower-cost applications. The combination of the mixing rod 15, the mixing impeller 16, and the motor 17 enables the entire mixing device to operate efficiently within the tank 1. Through the rotation of the mixing impeller 16, the materials in the tank are fully contacted and mixed with the cleaning liquid, and impurities and contaminants on the surface of the materials are washed away by mechanical force.
[0027] Specifically, the impeller 16 can be arranged in multiple layers along the length of the stirring rod 15. The impeller 16 includes multiple blades, which are evenly distributed around the circumference of the stirring rod 15. The blades can be curved and spirally arranged along the side wall of the stirring rod 15, with each blade having the same spiral direction (not shown in the figure). This design allows the water flow to form a spiral motion, more effectively mixing the materials and cleaning liquid. The blades can also be flat or vertical. Flat blades have a simple structure and low manufacturing cost, making them suitable for mass production; vertical blades can be directly mounted vertically on the stirring rod 15, suitable for applications requiring rapid and uniform mixing.
[0028] Reference Figure 1 Multiple baffles 18 are fixedly installed on the inner wall of the tank 1, and the baffles 18 are evenly distributed along the circumference of the tank 1. The multiple equally spaced baffles 18 form a complex flow path, forcing the liquid to reflux multiple times within the tank 1, thus enhancing the turbulence effect. In this way, even some fine impurities can be thoroughly washed away, improving the thoroughness and uniformity of cleaning. In addition, the presence of the baffles 18 can also slow down the eddies generated by the stirring impeller 16, prevent excessive dispersion of materials, maintain an appropriate degree of aggregation, and facilitate subsequent separation operations.
[0029] Specifically, the height of baffle 18 can be set to one-third to one-half of the height of the tank 1. This effectively blocks large particles of impurities without affecting the normal flow of materials. The material of baffle 18 can be stainless steel, which is highly corrosion-resistant and has a wide range of applications; or high-strength plastic, which is lightweight and easy to install and replace. The shape of baffle 18 can be designed as rectangular for easy processing and installation; or as triangular to reduce resistance and improve flowability.
[0030] Reference Figure 1 The guide section 14 is an inclined structure located at the bottom of the tank body 1. The raw material outlet 13 is located on the side wall of the tank body 1, close to the bottom of the tank body 1. The guide section 14 is inclined downwards in the direction close to the raw material outlet 13. The specific inclination angle of the guide section 14 is 3°-5°, so that fixed impurities can be smoothly discharged from the raw material outlet 13 under the action of gravity.
[0031] The implementation principle of a stirring tank for lithium carbonate production according to an embodiment of this application is as follows: By optimizing the design of the stirring device and the flow guide 14, the problem of fixed impurity accumulation in traditional stirring tanks is solved. Specifically, the multi-layered propeller impeller 16 can effectively promote the mixing of materials and cleaning liquid, improving the cleaning effect; while the special design of the flow guide 14 can promptly discharge fixed impurities under the action of gravity, maintaining the cleanliness and working efficiency of the stirring tank. This improvement not only enhances the cleaning capacity of the stirring tank but also extends the service life of the equipment, reduces maintenance costs, and significantly improves the overall process flow of lithium carbonate production.
[0032] Example 2
[0033] Reference Figure 2 The difference from the previous embodiment is that the guide section 14 is a conical structure located at the bottom of the tank 1, and the raw material outlet 13 is located at the bottom of the cone of the guide section 14. The conical structure design gradually reduces the space at the bottom of the tank 1, allowing fixed impurities to naturally collect at the bottom of the cone under gravity. This allows all fixed impurities to be easily discharged at a single point (i.e., the raw material outlet 13), simplifying the slag removal process. Compared to planar or sloping structures, the conical structure provides better slag removal, especially when handling high-concentration solid impurities.
[0034] Specifically, the inclination angle of the conical guide section 14 can be set according to actual needs, typically between 10° and 45°. This ensures the angle is neither too steep, making it difficult for materials to enter, nor too flat, affecting slag discharge. The material of the conical structure can also be stainless steel or high-strength plastic, chosen flexibly based on the actual usage environment and economic conditions. The diameter of the raw material outlet 13 at the bottom of the cone can be appropriately increased to facilitate the smooth discharge of fixed impurities.
[0035] Example 3
[0036] Reference Figure 3 The difference between this embodiment and Embodiments 1 and 2 is that the guide section 14 is an arc-shaped structure located at the bottom of the tank 1, and the raw material outlet 13 is located at the bottom of the arc of the guide section 14. The arc-shaped design eliminates sharp edges and flat areas at the bottom of the tank 1, making it difficult for fixed impurities to remain there. Instead, they slide off the arc surface, eventually converging at the bottom and being discharged through the raw material outlet 13. This not only reduces the accumulation of fixed impurities but also improves the utilization rate of the tank 1 and expands the effective cleaning area.
[0037] Specifically, the radius of the arc-shaped structure can be set to approximately two-thirds of the width of the tank 1. This ensures sufficient space to accommodate fixed impurities without occupying too much effective volume. The material for the arc-shaped structure can be stainless steel or high-strength plastic, depending on the usage environment and economic conditions. The diameter of the raw material outlet 13 at the bottom of the arc can be appropriately increased to facilitate the smooth discharge of fixed impurities.
[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
