Abstract
Description
Technical Field
[0001] This utility model relates to the field of extraction and purification technology, and in particular to a purification device for zinc extraction by extraction method. Background Technology
[0002] In the field of zinc extraction and impurity removal, traditional processes generally suffer from problems such as insufficient mixing, low separation efficiency, high equipment energy consumption, and poor stability, which seriously restrict the development of the industry. Existing technologies mostly adopt a combination of single-stage stirring and static sedimentation, which makes it difficult to achieve efficient mixing of the extractant and zinc-containing solution. This results in insufficient complexation reaction of impurity ions, leaving a large amount of impurities in the aqueous phase, affecting the purity of subsequent zinc extraction. At the same time, due to the lack of enhanced mass transfer methods, the contact area between the two phases is limited, and the extraction process is time-consuming and cannot meet the needs of continuous production.
[0003] In the separation process, conventional equipment relies on centrifugation or gravity sedimentation alone, which cannot separate large and small particles. Although large impurities can be separated quickly by centrifugation, the separation effect on small impurity particles is poor, which can easily cause organic phase entrainment and loss, resulting in waste of extractant and increased production costs. In addition, the structure of traditional separation equipment is dispersed, and multiple stages need to be connected in series to achieve stepwise separation of impurities of different particle sizes, which not only occupies a lot of space, but also increases the difficulty of equipment maintenance and failure rate.
[0004] In terms of power system, traditional equipment often uses independent motors to drive stirring and conveying separately, resulting in complex equipment structure, high energy consumption, poor coordination of various components, and problems such as uneven mixing and conveying blockage. Some equipment even relies on manual adjustment of operating parameters, making it difficult to accurately control the mixing and separation process. Improper operation often leads to emulsification, causing separation failure and production interruption.
[0005] As the zinc smelting industry continues to demand higher product purity and production efficiency, the limitations of traditional processes are becoming increasingly apparent. Their inefficient mixing and extraction, extensive separation methods, high-energy-consuming power systems, and unstable operating conditions not only make it difficult to improve the purity of zinc extraction, but also increase the production costs and environmental pressures of enterprises.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.
[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0028] Please see Figure 1-4 This utility model provides a technical solution: a purification device for zinc extraction by extraction method, including a shell 1, a solution inlet 2 and an extractant inlet 3 fixedly connected to the top of the shell 1, a conveying pipe 10 fixedly connected to the bottom of the shell 1, a stirring shaft 4 rotatably connected to the top of the shell 1, a driven sprocket 5 and a stirring blade 8 fixedly connected to both ends of the stirring shaft 4 respectively, and a cyclone separator is provided at the outlet of the conveying pipe 10.
[0029] The zinc-containing solution and the organic extractant enter from the solution inlet 2 and extractant inlet 3 above the shell 1, respectively. The extractant selectively complexes impurity ions to form hydrophobic complexes that enter the organic phase, while the zinc ions remain in the aqueous phase. The stirring shaft 4 and stirring blades 8 rotate at high speed, breaking the two liquid phases into tiny droplets, increasing the contact area, promoting the extraction reaction, and transporting the mixed solution into the hydrocyclone separator through the conveying pipe 10.
[0030] The cyclone separator includes: a cyclone chamber 12, a dilute phase discharge pipe 13, a dense phase discharge pipe 14, and an inclined plate 15;
[0031] The cyclone chamber 12 is fixedly connected to the outlet end of the conveying pipe 10, and the dilute phase discharge pipe 13 is fixedly installed above the cyclone chamber 12.
[0032] The dense phase discharge pipe 14 is fixedly installed at the bottom of the cyclone chamber 12, and the inclined plate 15 is fixedly installed in the middle of the inside of the cyclone chamber 12;
[0033] The outlet end of the conveying pipe 10 is injected tangentially into the swirl chamber 12. The high end of the inclined plate 15 is located at the dense phase discharge pipe 14, and the low end of the inclined plate 15 is located at the dense phase discharge pipe 14.
[0034] A dual-shaft extension motor 9 is fixedly installed on the side of the outer casing 1. A drive sprocket 7 is fixedly installed on the upper output shaft of the dual-shaft extension motor 9. A chain 6 meshes and connects the drive sprocket 7 and the driven sprocket 5.
[0035] The lower output shaft of the dual-shaft extension motor 9 is fixedly equipped with a spiral blade 11, and the conveying pipe 10 is fixedly installed below the dual-shaft extension motor 9;
[0036] The output shaft of the dual-shaft extension motor 9 drives the active sprocket 7 to rotate, which in turn drives the driven sprocket 5 to rotate via the chain 6, thereby driving the stirring shaft 4 and stirring blades 8 to rotate. The lower output shaft of the dual-shaft extension motor 9 drives the spiral blades 11 to rotate, forcibly conveying the mixture to the tangential conveying pipe 10. The axial thrust of the spiral conveying ensures that the mixture is tangentially injected into the swirling chamber 12. The mixture forms a strong rotating flow field in the swirling chamber 12. The denser aqueous phase is thrown towards the chamber wall and flows spirally downward along the wall, while the less dense organic phase converges towards the center, forming an upward flow column, which is discharged through the dilute phase discharge pipe 13.
[0037] The inclined plate 15 in the upper part of the swirling chamber 12 divides the fluid into multiple thin-layer channels. Tiny organic phase droplets that are not completely separated by the swirling flow rise rapidly along the upper surface of the inclined plate 15 under the action of buoyancy, converge to the top of the swirling chamber 12, and are discharged through the dilute phase discharge pipe 13. The aqueous phase slides down along the lower surface of the inclined plate 15, superimposed with the downward flow of the swirling flow field, and is finally discharged through the dense phase discharge pipe 14.
[0038] Working principle: During use, the zinc-containing solution and the organic extractant enter from the solution inlet 2 and extractant inlet 3 of the outer shell 1, respectively. The dual-shaft extension motor 9 drives the upper output shaft, which drives the stirring shaft 4 and stirring blades 8 to rotate via the active sprocket 7, driven sprocket 5 and chain 6, breaking up the two-phase liquid and promoting the complexation of impurity ions by the extractant. The impurities enter the organic phase, while the zinc ions remain in the aqueous phase. The lower output shaft of the dual-shaft extension motor 9 drives the spiral blades 11 to tangentially inject the mixture into the swirling chamber 12 through the conveying pipe 10. The mixture forms a swirling field in the swirling chamber 12. Due to its high density, the aqueous phase is thrown towards the chamber wall and flows downward, while the loaded organic phase converges towards the center and is discharged through the dilute phase outlet pipe 13. The inclined plate 15 separates the fluid into layers. Tiny organic phase droplets float up along the inclined plate 15 and are discharged through the dilute phase outlet pipe 13, while the aqueous phase slides down along the inclined plate 15 and is discharged through the concentrated phase outlet pipe 14.
[0039] The dual-shaft extension motor 9 drives the upper output shaft, which in turn drives the stirring shaft 4 and stirring blades 8 to rotate via the active sprocket 7, driven sprocket 5 and chain 6. This fully breaks down and mixes the zinc-containing solution with the organic extractant, greatly increasing the contact area between the two phases and enabling the extractant to quickly and fully complex impurity ions, thus significantly improving the extraction efficiency. The lower output shaft of the same dual-shaft extension motor 9 drives the spiral blades 11 to force the mixture to be transported to the conveying pipe 10, reducing the need for additional power devices, simplifying the structure and reducing energy consumption.
[0040] The mixture is tangentially injected into the swirling chamber 12 through the conveying pipe 10 to form a swirling flow field. Initial separation is achieved by utilizing density differences. The inclined plate 15 in the swirling chamber 12 further divides the fluid. Through the principle of shallow pool, the tiny organic phase droplets are deeply separated, so that the loaded organic phase is discharged through the dilute phase discharge pipe 13 and the aqueous phase is discharged through the concentrated phase discharge pipe 14, which greatly improves the separation effect and purity. All components work closely together, and the conveying of the spiral blade 11 ensures the stable flow of the mixture and avoids blockage, ensuring that the device can work stably and continuously for a long time.
[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
