Description

Technical Field

[0001] This utility model belongs to the field of cobalt-nickel-manganese extraction technology, specifically relating to a saponification stirring tank with stable operation. Background Technology

[0002] In the cobalt-nickel-manganese extraction industry, saponification and stirring are key steps in solvent extraction processes, primarily used to optimize the performance of the extractant and improve the separation efficiency and recovery rate of cobalt.

[0003] The core functions of saponification stirring are as follows:

[0004] 1) Improve the activity of the extractant

[0005] Reaction principle: Acidic extractants (such as P204, Cyanex 272) are reacted with alkaline solutions (NaOH or NH3·H2O) to generate extractants in the form of sodium soap or ammonium soap (such as Na-P204), which enhances their selective binding ability to cobalt ions.

[0006] Example of chemical formula: P204(H2A2) + 2NaOH → Na2A2 + 2H2O (After saponification, the extractant is more likely to form a complex with Co²⁺).

[0007] 2) Adjust the pH value of the organic phase

[0008] The saponification process consumes H⁺, increasing the alkalinity of the organic phase, which enables it to capture cobalt ions (Co²⁺) more efficiently in subsequent extraction, while inhibiting the co-extraction of impurity metals (such as Fe³⁺ and Mn²⁺).

[0009] 3) Reduce the formation of the third phase

[0010] Thorough stirring can prevent the "third phase" (emulsion layer) caused by incomplete saponification reaction, ensure rapid separation of the organic phase and aqueous phase, and reduce entrainment losses.

[0011] 4) Extend the lifespan of the extractant

[0012] By removing acidic degradation products (such as free acid) from the extractant, corrosion of the equipment is reduced and the service life of the organic phase is extended.

[0013] In actual operation, the saponification tank is relatively light in weight because the material is stirred during use. After a long period of use, it is easy for the original installation position to shift, the concentricity between the stirring and the tank body is poor, the tank is prone to deformation and damage, and the replacement / maintenance cycle of the pipeline is long, which affects production efficiency. Therefore, metal reinforcement is often used in the installation stage, such as adding multiple columns between the stirring steel structure and the tank body, but this takes up a large area and is costly. Summary of the Invention

[0014] To overcome the problems in the prior art where saponification tanks are prone to displacement from their original installation position, poor concentricity between the agitator and the tank, easy deformation and damage of the tank, and long replacement / maintenance cycles of the pipelines, thus affecting production efficiency, this utility model provides a saponification mixing tank with stable operation; it increases the overall stability of the equipment, has good operational stability, long service life, and low maintenance costs.

[0015] To achieve the above objectives, this utility model is implemented through the following technical solution: A stable saponification mixing tank mainly includes a tank 1, a mixing device 2, and a support frame 3. The tank 1 is a cylindrical tank made of PVC material with good chemical stability. The bottom of the tank 1 is provided with a mounting flange 11, and the side wall of the tank 1 is provided with annular reinforcing ribs 12 to increase its strength. The top of the tank 1 is provided with a top cover 13 connected by a flange 10. The tank 1 is provided with symmetrical reinforcing support ribs 14 on both sides, and a support seat 15 is provided on the top of the reinforcing support ribs 14. The support frame 3 is horizontally installed on the top of the support seat 15 by bolts. The mixing device 2 is installed on the support frame 3. The mixing shaft of the mixing device 2 passes through the top cover 13 and extends into the tank 1. The top cover 13 is provided with a feed inlet 16, and the bottom side of the tank 1 is provided with a discharge outlet 17.

[0016] Furthermore, the tank body of the tank 1 is provided with reinforcing ribs 18 between the mounting flange 11 and the flange 10.

[0017] The beneficial effects of this utility model are:

[0018] This utility model's tank is fixed by mounting flanges and bolts to prevent displacement during operation. By connecting the tank and the mixing device into a whole, the concentricity of the mixing device and the tank is ensured, avoiding deformation and damage caused by dryness due to displacement. The tank itself has high strength, increasing the overall stability of the equipment, resulting in good equipment operation stability, extending its service life, extending the maintenance cycle, ensuring production efficiency, and having a simple reinforcement structure with a small footprint, effectively reducing production costs.
