DETAILED DESCRIPTION

[0024] The following is a detailed description of a cobalt-nickel solution extraction device provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternative methods to implement them; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, an embodiment of the utility model provides an extraction device for cobalt-nickel solution, comprising: an extraction body 1 and a plurality of liquid storage parts 3, the extraction body 1 is divided into a mixing chamber 4 and a clarifying chamber 10 by a partition 9, the liquid storage part 3 comprises: a liquid storage tank 302; a connecting pipe 303, installed on the liquid storage tank 302, the connecting pipe 303 is used to connect the liquid storage tank 302 and the extraction body 1, and the connecting pipe 303 adopts a tangential direction to feed water to form a vortex.

[0026] The solution and the extractant first enter the mixing chamber 4, and after mixing, an organic phase and an aqueous phase containing metal ions are formed. The mixed solution then enters the clarification chamber 10. In the clarification chamber 10, due to the density difference, the organic phase and the aqueous phase will gradually separate. The organic phase is usually located in the upper layer, while the aqueous phase is located in the lower layer. The number and capacity of the multiple liquid storage tanks 302 must be designed to meet production needs to ensure the flexibility of continuous or batch processing. Each liquid storage tank 302 is loaded with different types of extractants, such as P204 sulfonated kerosene and P507. A precision pump and valve 2 are used to accurately adjust the required extractant ratio. An online mixer is set to ensure that the extractant is fully mixed before injection. The connecting pipe 1 303 adopts a tangential water inlet design, which can form a vortex in the liquid storage tank 302, promote uniform mixing of the solution and reduce dead zones, thereby improving fluid dynamics. Liquid inlets are provided on the extraction body 1 and the multiple liquid storage parts 3.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the liquid storage part 3 further includes: a variable frequency driver 301 installed on the liquid storage tank 302; a rotating member 304 installed on the variable frequency driver 301; and a plurality of stirring members 305 installed on the rotating member 304.

[0028] The variable frequency drive 301 is used to accurately control the rotation speed of the rotating part 304. By adjusting the rotation speed of the motor, the stirring speed can be controlled, so that the stirring intensity and fluidity can be adjusted according to different process requirements and material characteristics to achieve a more efficient mixing and reaction process.

[0029] The rotating member 304 is connected to a plurality of stirring members 305, and its main function is to transmit the power of the variable frequency drive 301 to the stirring members 305, driving them to perform efficient stirring operations. This structure enables the rotating member 304 to operate at different speeds and modes to meet different stirring requirements.

[0030] A plurality of stirring members 305 are in direct contact with the liquid to perform the actual stirring action. These stirring members 305 are usually designed into a specific shape, such as a streamlined shape or a spiral shape, to optimize the flow pattern and reduce eddy currents, thereby improving the mixing efficiency. By installing a plurality of stirring members 305 on a rotating member 304, a more extensive liquid stirring can be achieved, ensuring that every part of the liquid can be stirred evenly.

[0031] like Figure 1 , Figure 2 and Figure 6 As shown, the stirring part 2 is installed on the extraction body 1, and the stirring part 2 includes: a second frequency conversion driver 201; a second rotating member 202 installed on the second frequency conversion driver 201; and a plurality of second stirring members 203 installed on the second rotating member 202.

[0032] The variable frequency drive 201 is used to accurately control the rotation speed of the rotating part 202. By adjusting the rotation speed of the motor, the stirring speed can be controlled, so that the stirring intensity can be adjusted according to different process requirements and material characteristics to achieve a more efficient mixing and reaction process.

[0033] The main function of the rotating member 202 is to transmit the power of the variable frequency drive 201 to the stirring member 1 305, driving them to perform efficient stirring operations, so that the rotating member 202 can operate at different speeds and modes to adapt to different stirring needs. Multiple stirring members 203 are in direct contact with the liquid to perform actual stirring actions. These stirring members 203 are usually designed into specific shapes, such as streamlined or spiral shapes, to optimize flow patterns and reduce eddies, thereby improving mixing efficiency. By installing multiple stirring members 203 on the rotating member 202, a wider range of liquid agitation can be achieved, ensuring that every part of the liquid can be evenly stirred.

[0034] like Figure 6 As shown, the stirring member 203 is configured to be streamlined.

[0035] The purpose of setting the stirring element 203 into a streamlined shape is to reduce the resistance during the stirring process and improve the mixing efficiency. The streamlined stirring element 203 can effectively reduce the resistance encountered by the liquid or material during the stirring process. According to the principle of mechanics, when a streamlined object is in motion, its shape can better adapt to the flow of the fluid, so it can significantly reduce the friction resistance and pressure difference resistance. This is closely related to the working method of the agitator, because the agitator needs to drive the liquid flow by rotation to achieve uniform mixing of the materials. The streamlined design can cut into the liquid more smoothly, reduce the additional resistance caused by the shape, thereby improving the stirring efficiency and reducing energy consumption. The streamlined design also helps to reduce eddy currents and turbulence in the liquid. When the liquid is driven by the agitator, its internal flow velocity and direction will change. If the design of the stirring element 203 cannot guide the liquid flow well, irregular flow states, namely eddy currents, will easily form inside the liquid. These eddy currents not only affect the uniformity of stirring, but also may cause the movement path of the material in the agitator to become unpredictable, thereby reducing the mixing efficiency. The streamlined stirring element can more effectively guide the liquid flow, reduce the generation of eddy currents, promote the overall uniformity of the material, further optimize the flow state of the liquid, make the stirring more sufficient, and increase the mixing efficiency.

[0036] like Figure 2 , Figure 3 and Figure 5 As shown, multiple connecting pipes 2 8 are installed on the partition 9, and multiple connecting pipes 2 8 are all provided with valve 1. Multiple connecting pipes 2 8 are all made of corrosion-resistant and wear-resistant materials, and valve 2 is provided on connecting pipe 1 303.

[0037] The connecting pipe 2 8 made of corrosion-resistant and wear-resistant materials can effectively prevent the corrosion of the pipeline by chemical substances, thereby reducing the risks caused by leakage and corrosion. The use of this material prolongs the service life of the equipment and reduces maintenance costs. By installing a valve 1 on the connecting pipe 2 8, precise control of the fluid flow can be achieved, which is particularly important for chemical processes that require accurate adjustment of the reactant addition rate, ensuring that the chemical reaction is carried out according to the established steps and conditions, thereby improving the utilization rate of raw materials.

[0038] like Figure 2 and Figure 5 As shown, a plurality of baffles 5 are installed in the clarification chamber 10, and the baffles 5 are inclined to reduce the turbulence of the fluid.

[0039] The inclined design of the baffle 5 not only helps to guide the flow of the fluid, but also can effectively reduce the turbulence of the fluid in the container, thereby promoting a more efficient and faster phase separation process. The inclined setting of the baffle 5 can effectively change the flow path of the fluid, causing the fluid to rise slowly, thereby reducing the turbulence caused by direct rise. In this way, the baffle 5 not only optimizes the flow state of the fluid, but also improves the efficiency and quality of the two-phase separation.

[0040] like Figure 2 and Figure 5 As shown, the organic phase outlet 7 is arranged on the clarification chamber 10; the water phase outlet 6 is arranged on the clarification chamber 10, and valves three are arranged on the organic phase outlet 7 and the water phase outlet 6.

[0041] The reasonable design of the organic phase outlet 7 and the aqueous phase outlet 6 and the valve 3 equipped therewith make this process more precise and controllable. After the extraction process is completed, the organic phase and the aqueous phase need to be effectively separated. By respectively arranging the organic phase outlet 7 and the aqueous phase outlet 6 on the clarification chamber 10, it can be ensured that the two phases can be correctly guided out through their respective outlets after separation to avoid cross contamination. The setting of the valve 3 is to accurately control the outflow rate of the organic phase and the aqueous phase. This control is very important for maintaining the stability of the production process and optimizing the quality of the product. By adjusting the valve 3, it can be ensured that the fluid flows at a predetermined rate, thereby efficiently managing the entire extraction process, and the valve 3 can also prevent the fluid from flowing back. In some cases, if the pressure in the pipeline changes, it may cause the fluid to flow in the opposite direction, which may cause re-mixing or contamination between the phases. By closing valve three, this problem can be effectively avoided to ensure the one-way flow of the fluid. Valve three is set at the organic phase outlet 7 and the aqueous phase outlet 6, and samples can be easily extracted from the system for quality inspection when necessary. Especially in the fields of pharmaceutical production and fine chemicals, the use of valve three not only improves the controllability of the system, but also simplifies operation and maintenance. The operator can control the entire system through simple valve switching actions without entering the equipment or performing complicated operations, which greatly improves work efficiency and safety.

[0042] The technical solution provided by the utility model is that when in use, the cobalt-nickel solution is added into the mixing chamber 4, and different types of extractants are added according to the use requirements, such as P204 sulfonated kerosene and P507, etc. The frequency conversion driver 201 is operated to drive the rotating member 202 and the stirring member 203 to rotate, so that the liquid in the mixing chamber 4 is fully mixed, and then enters the clarifying chamber 10 through the baffle 5. In the clarifying chamber 10, due to the density difference, the organic phase and the aqueous phase are gradually separated.

[0043] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
