[0051] like Figure 1 As shown, this embodiment provides a reactor, which is a reaction vessel for completing processes such as sulfidation, nitration, hydrogenation, hydrocarbonization, polymerization, condensation, etc. The reactor comprises a reactor body 1, which is used to contain reaction materials and perform chemical reactions. In this embodiment, the reactor is used as a reaction vessel for high-pressure acid leaching of laterite nickel ore for illustration.

[0052] Optionally, the reactor further comprises a stirring device 2, which is rotatably connected to the reactor body 1 to mix the reaction materials evenly and accelerate the reaction speed.

[0053] Optionally, the reactor further comprises a spoiler 3, which is arranged on the inner wall of the reactor body 1, and is used to disturb the material in the reactor body 1 to enhance the turbulent mixing effect of the stirring device 2. However, the back side of the spoiler 3 is prone to produce a wake zone, and the material flow rate in the wake zone is low, which is prone to the problem of material deposition and scaling. The back side of the spoiler 3 is the side of the spoiler 3 that is away from the material rotation direction.

[0054] In order to solve the above problems, Figure 1-Figure 5 As shown, the reactor provided in this embodiment also includes a driving device 4, and the spoiler 3 is movably installed on the inner wall of the reactor body 1. The driving device 4 is connected to the spoiler 3 and is used to drive the spoiler 3 to move. When used specifically, the stirring device 2 can stir the material to accelerate the flow of the material, and the spoiler 3 can disrupt the flow trajectory of the material, thereby achieving the effect of turbulent mixing. At the same time, the driving device 4 drives the spoiler 3 to move. During the movement of the spoiler 3, the material on the back side thereof will be disturbed to a certain extent, thereby accelerating the dispersion of the material on the back side of the spoiler 3 and avoiding the formation of a wake zone, thereby solving the problem of material deposition and scaling.

[0055] Combination Figure 2-Figure 10 The specific structure of the driving device 4 is described as follows. Figure 2-Figure 10 As shown, the driving device 4 includes a shell 41, an impeller 42 and a transmission assembly. The shell 41 is arranged in the kettle body 1. The shell 41 is provided with an installation cavity 411 and an inlet 412 and an outlet 413 connected to the installation cavity 411. The inlet 412 is used for introducing steam. The impeller 42 is rotatably installed in the installation cavity 411. The impeller 42 is connected to the spoiler 3 through the transmission assembly. The driving device 4 drives the spoiler 3 to swing.

[0056] like Figure 2-Figure 4 and Fig.11 As shown, the spoiler 3 is provided with a rotating shaft 31, and the spoiler 3 is rotatably installed on the inner wall of the kettle body 1 along the axis in the vertical direction through the rotating shaft 31. The driving device 4 is connected to the rotating shaft 31, so that the driving device 4 can drive the spoiler 3 to rotate or swing back and forth within a certain angle. The purpose of accelerating the dispersion of the material on the back side of the spoiler 3 is achieved through the rotation and swinging of the spoiler 3.

[0057] Optionally, the spoiler 3 is in the shape of an elongated strip, and the rotating shaft 31 is formed by at least partially extending outward from both ends of the spoiler 3 in the length direction, and the rotating shaft 31 is set away from the center line of the width direction of the spoiler 3, and the spoiler 3 can be divided into two parts along the axis of the rotating shaft 31, one part faces the kettle cavity, and the other part faces the inner wall of the kettle body 1, the size of the part facing the kettle cavity is larger than the part facing the inner wall of the kettle body 1, and the driving device 4 drives the spoiler 3 to swing around the axis of the rotating shaft 31.

[0058] In this embodiment, when the laterite nickel ore undergoes high-pressure acid leaching reaction in the kettle body 1, high-temperature and high-pressure steam is injected into the kettle body 1. The high-temperature and high-pressure steam provides a high-pressure and high-temperature reaction environment, which is conducive to the reaction between the ore pulp and the acid, and the steam can be used as a driving source for driving the spoiler 3 to swing, that is, the shell 41 is fixedly installed in the kettle body 1, and the shell 41 is provided with a mounting cavity 411 and an inlet 412 and an outlet 413 connected to the mounting cavity 411. The impeller 42 is rotatably installed in the mounting cavity 411 along the vertical direction, and the middle part of the impeller 42 is connected to the rotating shaft 31 through a transmission component, and the inlet 412 is connected to the steam source in the plant through a pipeline. Since the shell 41 is located in the kettle cavity of the kettle body 1, the outlet 413 is connected to the kettle cavity. When the steam enters the mounting cavity 411 through the inlet 412, it will drive the impeller 42 to rotate, and the impeller 42 drives the spoiler 3 to swing back and forth through the transmission component. With this arrangement, there is no need to set an additional driver, and only the steam required for the reaction is used to drive the spoiler 3 to move, thereby reducing energy consumption.

[0059] like Figure 5-Figure 8 As shown, the transmission assembly includes a turntable 43, a first connecting rod 44 and a second connecting rod 45. The turntable 43 is rotatably mounted on the housing 41, the impeller 42 is coaxially connected to the turntable 43, one end of the first connecting rod 44 is rotatably connected to the turntable 43 and its rotation axis is spaced apart from the axis of the turntable 43, the other end of the first connecting rod 44 is rotatably connected to one end of the second connecting rod 45, and the other end of the second connecting rod 45 is fixedly connected to the rotating shaft 31.

[0060] like Figure 5-Figure 9 As shown, the turntable 43 is rotatably installed on the housing 41 along the axis in the vertical direction, and the turntable 43 is coaxially arranged with the impeller 42, and the impeller 42 is connected to the turntable 43, so that the turntable 43 is driven to rotate through the impeller 42, and a connecting column 4331 is provided on the turntable 43, and the connecting column 4331 is eccentrically arranged with the turntable 43, one end of the first connecting rod 44 is rotatably installed on the connecting column 4331 along the axis in the vertical direction, the first connecting rod 44 and the second connecting rod 45 are rotatably connected in turn, and the second connecting rod 45 is fixedly connected to the rotating shaft 31, when the impeller 42 drives the turntable 43 to rotate, the turntable 43 can drive the first connecting rod 44 and the second connecting rod 45 to move, thereby driving the spoiler 3 to swing within a certain angle.

[0061] like Figure 6-Figure 10 As shown, the turntable 43 includes a disk body 431, two limit blocks 432, a slider 433 and a screw rod 434. The disk body 431 is provided with a T-slot 4311, and the T-slot 4311 is extended in the radial direction of the disk body 431. The two limit blocks 432 are fixedly installed at both ends of the T-slot 4311. The slider 433 is adapted to the T-slot 4311. The slider 433 is slidably installed in the T-slot 4311. The slider 433 is provided with a threaded hole. The two ends of the screw rod 434 are rotatably installed on Two limit blocks 432 and a slider 433 are threadedly matched with a screw rod 434 through a threaded hole, so that the slider 433 can be driven to slide by rotating the screw rod 434, and a connecting column 4331 is arranged on the slider 433, so that the connecting column 4331 can be driven to move through the slider 433, so as to adjust the distance from the connecting column 4331 to the center of the disk body 431, and then adjust the swing amplitude of the spoiler 3. Such a setting can adjust the swing amplitude of the spoiler 3 according to actual conditions to achieve a better spoiler effect.

[0062] In another embodiment, the spoiler 3 is rotatably arranged in the kettle body 1, and the transmission assembly includes a driving gear and a driven gear, the driving gear is coaxially connected to the impeller 42, and the driven gear is installed on the rotating shaft 31, and the driving gear is meshed with the driven gear, so that when the impeller 42 rotates, the driving gear and the driven gear are meshed, thereby driving the spoiler 3 to rotate.

[0063] In this embodiment, the reactor is a horizontal reactor. In order to allow the slurry to react fully, one end of the reactor body 1 is the feed end and the other end is the discharge end. A plurality of partitions 5 are arranged in sequence in the reactor cavity of the reactor body 1 along the material flow direction. The plurality of partitions 5 divide the reactor cavity into a plurality of compartments connected at the upper part. The compartments at the two ends of the plurality of compartments correspond to the feed end and the discharge end. Acid leaching reaction will be carried out in each compartment, so each compartment is provided with a stirring device 2, and therefore a spoiler 3 needs to be arranged in each compartment. The spoiler 3 can be arranged on the inner side wall of the reactor body 1 or on the partition 5. Taking the spoiler 3 being arranged on the partition 5 as an example, the shell 41 is fixedly installed in the middle of the upper end of the partition 5, and two mounting protrusions 51 spaced apart in the vertical direction are arranged on opposite sides of the partition 5. A rotating shaft hole is arranged through the mounting protrusion 51, and the rotating shaft 31 is rotatably installed in the rotating shaft hole, so that the spoiler 3 can rotate, and one end of the second connecting rod 45 is fixedly connected to the rotating shaft 31 located above.

[0064] Alternatively, if Figure 3-Figure 5 As shown, two transmission assemblies are provided, and the two transmission assemblies are respectively connected to the spoilers 3 on both sides of the partition 5, so as to simultaneously drive the spoilers 3 on both sides to swing through the impeller 42.

[0065] In this embodiment, in order to simplify the structure of the driving device 4 and reduce the space occupied in the kettle body 1, the impeller 42 is fixedly connected to the two turntables 43, so that the two turntables 43 are driven to rotate at the same time by the impeller 42, and then the spoilers 3 on both sides of the partition 5 are driven to move at the same time through the corresponding transmission components. Such a setting can reduce the number of driving devices 4, reduce the volume, and avoid occupying too much space.

[0066] Alternatively, if Figure 8 As shown, the impeller 42 is located between the two transmission components so that the impeller 42 is subjected to balanced force, so that the impeller 42 can better drive the two transmission components to move.

[0067] In this embodiment, the installation cavity 411 is open at both ends, and two turntables 43 are adapted to the installation cavity 411. The two turntables 43 are rotatably installed at the upper and lower ends of the installation cavity 411 along the vertical direction. The upper and lower ends of the impeller 42 are connected to the corresponding turntables 43. Such an arrangement can form a space for accommodating the impeller 42 by enclosing the two turntables 43 and the shell 41, and the structure is compact.

[0068] like Figure 3-Figure 5 As shown, in order to improve the spoiler effect, three spoilers 3 are arranged on each side of the partition 5, the three spoilers 3 are arranged at intervals, and the three spoilers 3 are connected by a connecting member 9 so that the multiple spoilers 3 swing synchronously. Of course, the number of spoilers can also be one, two, four or more, which can be adaptively selected according to actual needs.

[0069] Specifically, a mounting column 3232 is provided in the middle of one side of each spoiler 3 facing the partition 5, and a plurality of mounting holes are provided on the connecting piece 9, and the plurality of mounting holes correspond one to one to the plurality of mounting columns 3232. A gear is provided on the outer periphery of the mounting column 32, and a rack is provided in the mounting hole. The gear and the rack are meshed, so that when the driving device 4 drives one of the spoilers 3 to move, the plurality of spoilers 3 can be driven to move synchronously through the connecting piece 9.

[0070] Optionally, in order to extend the time it takes for the bottom of the kettle body 1 to be worn through, a wear-resistant plate 8 is provided on the inner bottom wall of the kettle body 1. Providing the wear-resistant plate 8 is essentially equivalent to increasing the thickness of the bottom of the kettle body 1 which is prone to wear, extending the time it takes for the bottom of the kettle body 1 to be worn through, and thereby extending the service life of the reactor.

[0071] Optionally, the wear-resistant plate 8 is a titanium alloy plate, which has the properties of acid corrosion resistance and wear resistance.

[0072] Optionally, the wear-resistant plate 8 is provided with a cavity, and the cavity is connected to a plurality of pores. The pores are arranged on the side of the wear-resistant plate 8 facing the kettle cavity, that is, the pores are arranged upward, and the outlet 413 is connected to the plurality of pores through the connecting pipe 7. External steam enters the installation cavity 411 through the inlet 412 to drive the impeller 42 to rotate and then enters the kettle cavity from the outlet 413. In order to make full use of this part of the steam, the outlet 413 is connected to the cavity of the wear-resistant plate 8 through the connecting pipe 7, so that the steam enters the cavity of the wear-resistant plate 8 from the pores. Since the wear-resistant plate 8 is located at the bottom of the kettle body 1, when the steam enters the kettle cavity from the pores, it will disturb the material at the bottom of the kettle body 1. In conjunction with the stirring device 2, the reaction efficiency can be improved.

[0073] Optionally, the reactor also includes a steam pipe 6 and a regulating valve, one end of the steam pipe 6 extends into the reactor body 1 and is connected to the inlet 412, and the other end of the steam pipe 6 is used to connect to the steam source in the factory area. The regulating valve is arranged on the steam pipe 6 and is used to adjust the steam volume. By adjusting the amount of steam entering the installation cavity 411 through the regulating valve, the rotation frequency of the impeller 42 can be controlled, thereby achieving the control of the swing frequency of the spoiler 3.

[0074] In order to better understand this application, the following Figure 1-Figure 11 The technical solution of this application is described in detail:

[0075] During specific use, the stirring device 2 can stir the material to accelerate the flow of the material. The spoiler 3 in the kettle body 1 can disrupt the flow trajectory of the material, thereby achieving the effect of turbulent mixing. At the same time, steam is transported to the installation cavity 411 through the steam pipe 6. The steam drives the impeller 42 to rotate. The impeller 42 drives the turntables 43 at the upper and lower ends to rotate. The turntables 43 respectively drive the corresponding first connecting rods 44 and second connecting rods 45 to move, thereby driving the spoiler 3 to swing. The spoiler 3 on the same side is connected by a connecting piece 9 so that it can swing synchronously. After the steam does work, it enters the wear-resistant plate 8 from the connecting pipe 7 and is discharged from the pores. When the steam enters the kettle cavity from the pores, it will disturb the material at the bottom of the kettle body 1. In conjunction with the stirring device 2, the reaction efficiency can be improved.
