[0044] The utility model will be further explained in detail in combination with the drawings and examples.It can be understood that the specific examples described here are only used to explain the utility model and not limited to the utility model.In addition, it should be noted that in order to facilitate the description, only the part related to the utility model is shown in the drawings and not all the structures.

[0045] In the description of the utility model, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated;It can be mechanically connected, or it can be electrically connected;It can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication inside two elements or the interaction relationship between two elements.For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0046] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0047] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0048] Currently, in the hydrometallurgical process for laterite nickel ore, a slurry, strong acid, and steam are typically injected into a reactor to extract nickel and cobalt. The slurry and strong acid are injected from the top of the reactor, along with high-temperature steam, creating a high-temperature, high-pressure, and highly acidic environment inside. To improve reaction efficiency, a stirring device is usually installed inside the reactor. However, some of the slurry settles at the bottom of the reactor under gravity, resulting in insufficient contact with the strong acid, affecting the reaction rate, and leading to incomplete reaction and waste of raw materials.

[0049] To solve the above problems, such as Figures 1-7 As shown, this embodiment provides a high-pressure leaching reactor with dual-power stirring. This reactor includes a reactor body 1, a stirring mechanism, and a drive assembly 3. The stirring mechanism includes a hollow shaft 21, a nozzle assembly 22, and a stirring component. The hollow shaft 21 is rotatably inserted into the reactor body 1, and a solution is connected to the outside of the hollow shaft 21. The hollow shaft 21 is connected to the nozzle assembly 22, which is positioned towards the inner bottom wall of the reactor body 1. The solution is sprayed from the nozzle assembly 22 to blow up the slurry deposited at the bottom of the reactor body 1. The stirring component is located on the outer periphery of the hollow shaft 21. The drive assembly 3 is mounted on the reactor body 1 and is configured to drive the hollow shaft 21 to rotate. In this embodiment, the solution is a strong acid oil.

[0050] The solution can flow in through the hollow shaft 21 and be sprayed out through the spray head assembly 22, and since the spray head assembly 22 is directed towards the inner bottom wall of the reactor body 1, the solution can impact and blow up the slurry deposited on the bottom of the reactor, effectively solving the problem of insufficient contact with the solution caused by slurry deposition; the stirring assembly arranged on the outer periphery of the hollow shaft 21 rotates with the rotation of the hollow shaft 21, further strengthening the mixing effect of the slurry and the solution and improving the reaction efficiency. The high-pressure leaching reactor with double-power stirring provided by the present application can blow up the slurry deposited on the bottom of the reactor body 1 under the action of water power, and the stirring assembly can stir the solution and the slurry under the action of mechanical power, significantly reducing the low reaction rate and insufficient reaction caused by slurry deposition and improving the extraction rate of nickel and cobalt.

[0051] It should be noted that the reactor body 1 is a tank structure that can be thought of by those skilled in the art, and for the sake of brevity, this embodiment will not be described and explained in detail. For example, the reactor body 1 can adopt a horizontal structure as shown in Figure 1 , or a vertical structure as shown in Figure 2 , which can all achieve the purpose of the present embodiment and are not limited.

[0052] Specifically, as shown in Figures 1-3 , the spray head assembly 22 includes a plurality of first spray heads 221, and the plurality of first spray heads 221 are arranged around the circumference of the hollow shaft 21 and are inclined away from the hollow shaft 21 in a vertically downward direction. The vertically downward direction is specifically shown by arrow B in Figure 1 , Figure 2 . The solution sprayed from the first spray heads 221 can form a jet flow with a certain angle and kinetic energy, which can more effectively impact and blow up the slurry deposited on the bottom of the reactor body 1; since the direction of the jet flow forms an angle with the bottom of the reactor body 1, the solution can more easily flow upwards along the inner wall of the reactor body 1 after impacting the slurry and mix with the upper layer of slurry; the first spray heads 221 arranged around the circumference of the hollow shaft 21 can ensure that the spraying range of the solution on the bottom of the reactor body 1 is more uniform, reduce the dead angle of slurry deposition, and make the slurry in the reactor body 1 more fully contact with the solution, thereby improving the reaction rate.

[0053] Further, as shown in Figures 1-3 , the spray head assembly 22 further includes a second spray head 222, and the second spray head 222 is arranged at the bottom end of the hollow shaft 21 and is arranged in a vertically downward direction. The solution sprayed from the second spray head 222 can directly impact the slurry on the bottom of the reactor body 1, so that the slurry on the bottom of the reactor body 1 can be effectively blown up, further increasing the coverage area of the spray head assembly 22.

[0054] Specifically, as shown inFigures 1-4 As shown, this stirring mechanism also includes an annular guide plate 23. Along the vertically downward direction, the annular guide plate 23 gradually expands to form a conical structure. The annular guide plate 23 is fixedly connected to the inner bottom wall of the reactor body 1. The annular guide plate 23 has a conical guiding surface, and several first nozzles 221 are parallel to the conical guiding surface. The conical guiding surface of the annular guide plate 23 can guide the solution sprayed from the first nozzles 221, allowing the solution to diffuse more evenly and flow upwards, more effectively flushing and agitating the deposited slurry. The conical guiding surface allows the solution sprayed from the first nozzles 221 to form a wider mixing zone when flushing the slurry, enabling the slurry and solution to have more complete contact and reaction, improving the mixing effect and reaction rate.

[0055] Since the annular guide plate 23 is fixed to the inner bottom wall of the reactor body 1 in a conical structure, the annular guide plate 23 and the inner bottom wall of the reactor body 1 form a semi-enclosed area. In order to facilitate the blowing out of the slurry deposited in this area, in this embodiment, the annular guide plate 23 is provided with several through holes 231, and the second nozzle 222 extends into the annular guide plate 23. The second nozzle 222 extends into the annular guide plate 23 to directly spray the solution into the semi-enclosed area to directly impact the slurry in this area. The blown-up slurry flows out through the through holes 231 onto the conical guide surface of the annular guide plate 23, and under the action of the first nozzle 221, it diffuses and flows upward with the solution sprayed by the first nozzle 221 to fully contact and react with the solution.

[0056] In this embodiment, there are multiple through holes 231, which are evenly arranged around the circumference of the annular guide plate 23. It can be understood that in this embodiment, the second nozzle 222 is positioned directly opposite the center of the bottom of the reactor body 1.

[0057] Specifically, such as Figures 1-4 As shown, the stirring mechanism also includes multiple support members 232, which are arranged at intervals along the circumference of the annular guide plate 23. One end of each support member 232 is connected to the annular guide plate 23, and the other end is connected to the inner bottom wall of the reactor body 1. The support members 232 provide additional support for the annular guide plate 23, enhancing its stability and preventing deformation or displacement of the annular guide plate 23.

[0058] Specifically, such as Figure 1 , Figure 2As shown, the stirring assembly comprises a stirring impeller 241 and an ascending impeller 242, which are arranged in a vertical downward direction in sequence, the ascending impeller 242 is used to drive the solution and slurry to flow in a vertical upward direction, and the stirring impeller 241 is used to drive the solution and slurry to diffuse around. The ascending impeller 242 can drive the slurry and solution blown upward to prevent the slurry from re-depositing at the bottom of the reactor body 1, and can drive the slurry and solution to the stirring impeller 241; the stirring impeller 241 can make the slurry and solution more fully contact to improve the reaction rate.

[0059] Specifically, as shown in Figure 5 The ascending impeller 242 comprises an inner ring 2421, an outer ring 2422 and ascending blades 2423, the inner ring 2421 is coaxially sleeved on the hollow shaft 21, the outer ring 2422 is coaxial with the inner ring 2421 and is connected by a plurality of ascending blades 2423, the plurality of ascending blades 2423 are arranged in a circumferential direction of the inner ring 2421, and the top of the ascending blade 2423 has an inclined surface 24231, which is inclined downward in the rotation direction of the ascending impeller 242. When the hollow shaft 21 rotates, the ascending impeller 242 also starts to rotate, and since the top of the ascending blade 2423 has the inclined surface 24231 inclined downward, when the solution and slurry flow through the inclined surface 24231, they will be subjected to an upward thrust to flow in a vertical upward direction. It should be noted that the specific number of the ascending blades 2423 is determined by actual needs, which is not limited in the embodiment.

[0060] For example, the rotation direction of the ascending impeller 242 in the embodiment is shown by an arrow C in Figure 5 The inclined surface 24231 gradually inclines toward the inner bottom wall of the reactor body 1 in the direction of the arrow C.

[0061] Specifically, as shown in Figure 6 The stirring impeller 241 comprises a stirring ring 2411 and a plurality of stirring blades 2412, the stirring ring 2411 is coaxially sleeved on the hollow shaft 21, and the plurality of stirring blades 2412 are arranged in a circumferential direction of the stirring ring 2411. When the hollow shaft 21 rotates, the stirring impeller 241 also rotates, and the stirring blades 2412 can drive the solution and slurry to form a circulating flow in the reactor body 1 in the rotating process, so that the solution and slurry are more fully contacted to improve the reaction rate.

[0062] In the embodiment, the stirring blades 2412 are vertical plates, and the extending direction of the vertical plates is perpendicular to the axis of the stirring ring 2411. When the vertical plates rotate, a large shear force and impact force can be generated on the solution and slurry, thereby enhancing the stirring intensity, making the slurry and solution mix more fully, and improving the reaction rate. It should be noted that the specific number of the stirring blades 2412 is determined by actual requirements, and the embodiment does not limit the same.

[0063] Specifically, as shown in Figure 1 、 Figure 2 , the high-pressure leaching reaction kettle with double-power stirring further comprises a liquid supply assembly 4 in communication with the hollow shaft 21 to deliver the solution into the hollow shaft 21. The liquid supply assembly 4 can directly deliver the solution into the hollow shaft 21, thereby improving the delivery efficiency of the solution.

[0064] In the embodiment, as shown in Figure 1 、 Figure 2 , the liquid supply assembly 4 comprises a water pump, a water inlet pipe and a backflow pipe. The water inlet end of the water pump is in communication with the inside of the reaction kettle body 1100 through the backflow pipe, and the water outlet end of the water pump is in communication with the hollow shaft 21 through the water inlet pipe. The solution inside the reaction kettle body 1 is pumped into the hollow shaft 21 by the water pump, and then flows from the hollow shaft 21 to the spray head assembly 22 and is sprayed out by the spray head assembly 22, so that the solution can impact and blow up the slurry deposited at the bottom of the reaction kettle body 1, effectively solving the problem of insufficient contact between the slurry and the solution due to deposition.

[0065] Specifically, as shown in Figure 1 、 Figure 2 、 Figure 7 , the high-pressure leaching reaction kettle with double-power stirring further comprises a rotary joint 5 having a cavity. The output end of the driving assembly 3 and the top end of the hollow shaft 21 are rotationally and sealingly connected to the rotary joint 5, and both the output end of the driving assembly 3 and the top end of the hollow shaft 21 extend into the cavity of the rotary joint 5 to be connected. The side wall of the part of the hollow shaft 21 located in the cavity is provided with a water inlet hole 211, and the liquid supply assembly 4 is in communication with the cavity. The driving assembly 3 can drive the hollow shaft 21 to rotate and ensure the sealing of the rotary joint 5. The solution can enter the cavity of the rotary joint 5 from the liquid supply assembly 4, enter the hollow shaft 21 through the water inlet hole 211, and then be sprayed out through the spray head assembly 22.

[0066] Specifically, as shown in Figure 1 、 Figure 2As shown, the driving assembly 3 comprises a driving member 31 and a shaft coupling 32, and the output end of the driving member 31 is coaxially connected with the hollow shaft 21 through the shaft coupling 32. The shaft coupling 32 can make the output end of the driving member 31 co-rotate with the hollow shaft 21 and transmit torque, so as to ensure that the output end of the driving member 31 can efficiently transmit power to the hollow shaft 21 and realize synchronous operation of the two; and the shaft coupling 32 has the functions of buffering and damping, can absorb and compensate the deviation between the output end of the driving member 31 and the hollow shaft 21, reduce vibration and impact, and improve the stability and service life of the high-pressure leaching reaction kettle with double-power stirring.

[0067] In the embodiment, the driving member 31 is a motor; in other embodiments, the driving member 31 is a cylinder. It should be noted that any structure capable of driving the hollow shaft 21 of the embodiment to rotate can be used as the driving member 31 of the embodiment, and the embodiment is not limited in this regard.

[0068] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled in the art, various obvious changes, re-adjustment and replacement can be made without departing from the protection scope of the utility model.
