DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example: like Figure 1-18 As shown, this embodiment provides an extraction mixing and stirring reactor dedicated to refining, comprising a fixed frame 10, a tank body 20 is arranged in the fixed frame 10, and a stirring shaft 14 is arranged in the tank body 20; The outer wall of the stirring shaft 14 is evenly provided with multiple groups of guide sleeves 50, and the stirring shaft 14 is rotatably arranged in the inner cavity of the guide sleeve 50. Two groups of stirring ring plates 30 are arranged on the guide sleeve 50, and multiple stirring components 40 are arranged between the two groups of stirring ring plates 30. The stirring components 40 are in contact with the guide sleeve 50. The stirring shaft 14 rotates, driving the stirring ring plates 30 and the stirring components 40 to rotate about the axis of the stirring shaft 14. The guide sleeve 50 guides the stirring components 40 to move back and forth in the radial direction of the stirring ring plates 30 to drive the material to move in multiple directions.

[0019] In this embodiment, when the material is extracted, the material is introduced into the tank body 20, and the stirring shaft 14 rotates, driving the stirring ring plate 30 to rotate. Since the stirring ring plate 30 is provided with multiple groups of stirring components 40, the stirring components 40 rotate as the stirring ring plate 30 rotates. At the same time, since the stirring components 40 cooperate with the guide sleeve 50, the stirring components 40 move back and forth on the stirring ring plate 30 during the rotation process, disturbing the material in the tank body 20, so that the material moves in multiple directions; The stirring ring plate 30 and the stirring assembly 40 are driven to rotate about the axis of the stirring shaft 14 by the rotation of the stirring shaft 14, and the stirring assembly 40 moves back and forth on the stirring ring plate 30, which can more effectively disturb the material and improve the stirring efficiency; Through the cooperation of the stirring assembly 40 and the guide sleeve 50, the material moves back and forth while rotating, which increases the contact frequency and contact area between the materials, thereby strengthening the extraction process. In addition, the design of the stirring assembly 40 allows for reciprocal movement on the stirring ring plate 30, which provides operational flexibility and allows the stirring intensity and method to be adjusted according to specific process requirements to meet different stirring requirements. At the same time, the reciprocating motion helps prevent the material from being deposited in the tank body 20 and maintains the fluidity of the material, which is particularly important for viscous or easily deposited materials. The multi-directional movement of the material in the tank 20 helps to improve the mixing uniformity. At the same time, the multi-directional movement helps to break the local concentration gradient in the material and also helps to promote heat exchange and mass transfer, thereby effectively improving the reaction rate and efficiency in the refining process.

[0020] Specifically, the stirring assembly 40 includes a stirring shell 41, which is connected between two groups of stirring ring plates 30. An elastic displacement rod 44 is arranged in the stirring shell 41, and the elastic displacement rod 44 is in contact with the guide sleeve 50. A stirring plate 43 is arranged on the elastic displacement rod 44, and the stirring plate 43 is arranged at an angle. The stirring plate 43 is arranged at one end away from the guide sleeve 50.

[0021] In this embodiment, when the stirring ring plate 30 rotates, the stirring assembly 40 is driven to rotate, that is, the stirring shell 41 is driven to rotate. Since the stirring shell 41 is connected between the two groups of stirring ring plates 30, the stirring ring plates 30 can be divided into a plurality of small compartments. When rotating, the materials are stirred in different areas during the rotation process, thereby improving the mixing efficiency. When the stirring ring plate 30 drives the stirring shell 41 and the stirring plate 43 to rotate, the material in the tank body 20 can be driven to rotate, forming a multi-phase flow movement, in which the dispersed phase floats or settles in the continuous phase depending on the density difference between the phases, and the continuous phase moves in the opposite direction to the dispersed phase under the action of the pressure difference and potential difference; The stirring shell 41 is connected between the two sets of stirring ring plates 30, and an elastic displacement rod 44 is provided in the stirring shell 41, so that the material can be reciprocated while rotating, thereby increasing the contact frequency and contact area between the materials, strengthening the extraction process, and facilitating the effective separation of the dispersed phase and the continuous phase. At the same time, the centrifugal force generated by the rotation causes the material to perform centrifugal motion along the radial direction of the stirring shaft 14, thereby strengthening the mixing of the material in the tower and increasing the residence time of the material in the tower, thereby improving the washing and extraction effect.

[0022] Specifically, a stirring sleeve 31 is disposed at the center of the stirring ring plate 30, and the stirring sleeve 31 is fixedly disposed on the outer wall of the stirring shaft 14; The stirring shell 41 is provided with a connecting plate 412 , and two groups of reinforcing plates 411 are provided on the connecting plate 412 . The connecting plate 412 and the reinforcing plates 411 are both connected to the outer wall of the stirring sleeve 31 , and the elastic displacement rod 44 is provided below the connecting plate 412 .

[0023] In this embodiment, when the stirring shaft 14 rotates, the stirring shaft 14 drives the stirring sleeve 31 to rotate, thereby driving the stirring ring plate 30 to rotate through the connecting plate 412 .

[0024] Specifically, a fixed pipe 46 is provided in the mixing shell 41; The fixed pipe 46 is provided with a displacement through hole 463, and the elastic displacement rod 44 is slidably set in the displacement through hole 463. A fixed surface 462 is also provided in the fixed pipe 46. A displacement plate 443 is fixedly set on the outer wall of the elastic displacement rod 44. The displacement plate 443 is slidably set in the inner cavity of the fixed pipe 46. A reset spring 461 is provided between the displacement plate 443 and the fixed surface 462, and the reset spring 461 is sleeved on the outer wall of the elastic displacement rod 44.

[0025] In this embodiment, the reset spring 461 is set to provide elasticity to the elastic displacement rod 44. When the elastic displacement rod 44 cooperates with the guide sleeve 50 and moves away from the stirring shaft 14, the reset spring 461 is in a compressed state, and when the elastic displacement rod 44 does not cooperate with the guide sleeve 50, the reset spring 461 resets and drives the elastic displacement rod 44 to reset.

[0026] Specifically, a plurality of flow channels 45 are provided between the fixed pipe 46 and the stirring shell 41 , and a fixed plate 464 is provided between the fixed pipe 46 and the stirring shell 41 ; The flow channel 45 is provided with a first flow cavity 451 and a second flow cavity 452 . The first flow cavity 451 is provided at the fixed surface 462 . A flow slope 453 is provided at the junction of the first flow cavity 451 and the second flow cavity 452 .

[0027] Specifically, an extrusion cavity 413 is provided in the stirring shell 41, and the extrusion cavity 413 is provided between the first flow cavity 451 and the stirring plate 43, and the sum of the capacities of the plurality of groups of flow channels 45 is smaller than the capacity of the extrusion cavity 413; The elastic displacement rod 44 is provided with a sealing plug 42 . The sealing plug 42 contacts the inner wall of the extrusion cavity 413 . The sealing plug 42 is slidably provided on the inner wall of the extrusion cavity 413 .

[0028] Specifically, the surface of the sealing plug 42 is evenly provided with four groups of guide slopes 421, and the surfaces of two groups of guide slopes 421 in the horizontal direction are provided with multiple groups of guide grooves 423; The sealing plug 42 is provided with a sealing portion 422, which is in close contact with the inner wall of the extrusion cavity 413. The sealing portion 422 moves in the extrusion cavity 413 toward the first flow cavity 451, so that the material passes through the extrusion cavity 413, the first flow cavity 451, and the second flow cavity 452 in sequence.

[0029] In this embodiment, when the elastic displacement rod 44 moves back and forth in the fixed pipe 46, the sealing plug 42 moves back and forth in the extrusion cavity 413; When the sealing plug 42 is away from the stirring shaft 14, since the stirring ring plate 30 is in a rotating state, the material can enter the extrusion cavity 413 through the guiding slope 421, and when the sealing plug 42 is displaced toward the stirring shaft 14 as the elastic displacement rod 44 is reset, the sealing portion 422 on the sealing plug 42 cooperates with the inner wall of the extrusion cavity 413 to extrude the material in the extrusion cavity 413, so that the material moves toward the stirring shaft 14 through the extrusion cavity 413, the first flow cavity 451, and the second flow cavity 452 in sequence, so as to strengthen the radial movement of the material, thereby enhancing the radial mixing of the material in the tank body 20, and the extrusion process of the material in the extrusion cavity 413 helps to increase the contact frequency and contact area between different phases, thereby improving the mass transfer efficiency, especially in the extraction and reaction process, and at the same time, the extrusion effect of the sealing plug 42 on the material in the extrusion cavity 413 increases the shear force between the materials, helps to refine the dispersed phase, and improves the mixing effect; Since the total capacity of the multiple groups of flow channels 45 is smaller than the capacity of the extrusion cavity 413 and under the guidance of the flow slope 453, the material will accelerate when moving from the extrusion cavity 413 to the first flow cavity 451 and the second flow cavity 452 to further improve the mixing efficiency.

[0030] Specifically, the stirring plate 43 is provided with a movable window 431; The sealing plug 42 is provided with two sets of movable plates 61, the two sets of movable plates 61 are arranged in the movable windows 431, the movable plates 61 are provided with movable rods 64, and the movable rods 64 are provided with movable holes 641; Two groups of support rods 63 are disposed on the sealing plug 42 . Support blocks 631 are disposed on both sides of the support rods 63 . The support blocks 631 are connected to the sealing plug 42 . The support rods 63 are disposed in the movable holes 641 .

[0031] Specifically, the movable plate 61 is provided with a movable blade 60, and an angle is provided between the movable blade 60 and the movable plate 61, and the angle is between 100° and 160°; The movable plate 61 is provided with a movable through slot 611 , in which a limiting rod 62 is arranged. The two groups of the limiting rod 62 match the positions of the two groups of stirring ring plates 30 . The two ends of the limiting rod 62 are provided with limiting blocks 621 , and the limiting blocks 621 are connected to the stirring ring plates 30 .

[0032] In this case, the length of the movable through slot 611 is set according to actual conditions.

[0033] In this embodiment, during the displacement of the elastic displacement rod 44, the sealing plug 42 is displaced along with the displacement of the elastic displacement rod 44, so that the support rod 63 on the sealing plug 42 is displaced, and during the displacement of the support rod 63, the support rod 63 drives the movable rod 64 to displace in the movable window 431, thereby driving the movable plate 61 to displace, and since the limit rod 62 is provided in the movable through groove 611, the limit rod 62 limits the displacement of the movable plate 61, ensuring that the movable plate 61 moves within a predetermined path; That is, when the sealing plug 42 is displaced in the direction away from the stirring shaft 14, the movable plate 61 first rotates with the axis of the limit rod 62, so that the movable blade 60 is fanned in the direction of the stirring shaft 14. When the limit rod 62 and the support rod 63 are in the same plane, the movable plate 61 is in a lifted state. When the sealing plug 42 continues to drive the support rod 63 to displace in the direction away from the stirring shaft 14, the support rod 63 drives the movable plate 61 to descend, and the movable plate 61 continues to rotate with the axis of the limit rod 62. When the movable plate 61 no longer descends and no longer rotates, the sealing plug 42 is displaced to the end of the stroke. At this time, the sealing plug 42 is reset to drive the movable blade 60 to fan. Of course, when the movable plate 61 is in the descending state, the material enters the extrusion cavity 413 through the guide slope 421; Through the linkage mechanism of the movable rod 64 and the support rod 63, the dynamic adjustment of the movable plate 61 is realized, and the flow path of the material in the tank body 20 can be changed, so that the flow of the material in the mixing process is smoother, the flow dead angle is reduced, the mixing efficiency, the uniformity of the material mixing and the transfer efficiency are improved, and the material can be effectively cut and dispersed, further refining the dispersed phase and enhancing the mixing effect of the material; Of course, when the sealing plug 42 moves to the end of the stroke, the movable plate 61 no longer descends and no longer rotates. With the cooperation of the movable through groove 611 and the limiting rod 62, the sealing plug 42 can be positioned to prevent the sealing plug 42 from moving too long and contacting the inner wall of the tank body 20.

[0034] Specifically, a displacement block 441 is disposed on the elastic displacement rod 44, and a displacement ball 442 is rotatably disposed inside the displacement block 441; The guide sleeve 50 is provided with a guide ring 55, and the guide ring 55 is provided with a guide block 56. The guide block 56 is provided with a stirring hole 53, and the stirring hole 53 is coaxially arranged with the guide sleeve 50. The guide block 56 is provided with multiple groups of guide rods 52, and the guide rods 52 are provided with a descending inclined surface 54. The guide rods 52 are provided with a first inclined surface 521 and a second inclined surface 523. A guide arc surface 522 is provided between the first inclined surface 521 and the second inclined surface 523, and the guide arc surface 522 is arranged away from the guide sleeve 50. The displacement ball 442 is displaced along the first inclined surface 521, the guide arc surface 522, and the second inclined surface 523, so that the elastic displacement rod 44 moves back and forth in the stirring shell 41; A guide reinforcement rod 51 is fixedly disposed on the outer wall of the guide sleeve 50 , and the guide reinforcement rod 51 is connected to the inner wall of the tank body 20 .

[0035] In this embodiment, when the elastic displacement rod 44 is reciprocatingly displaced, the displacement ball 442 first contacts the first inclined surface 521. When the elastic displacement rod 44 rotates with the stirring ring plate 30 about the axis of the stirring shaft 14, the displacement ball 442 is displaced on the first inclined surface 521 as the elastic displacement rod 44 rotates, so that the displacement plate 443 on the elastic displacement rod 44 squeezes the reset spring 461. When the displacement ball 442 is displaced to the guide arc surface 522, the displacement path of the elastic displacement rod 44 reaches the farthest distance, that is, the sealing plug 42 is displaced to the end of the stroke. During the continuous rotation of the elastic displacement rod 44, the displacement ball 442 contacts the second inclined surface 523, and the elastic displacement rod 44 is in a reset state, that is, the sealing plug 42 extrude the material in the extrusion cavity 413; The contact sequence design of the displacement ball 442 with the first inclined surface 521, the guide arc surface 522, and the second inclined surface 523 enables the elastic displacement rod 44 to reset and displace on a specific path. This design optimizes the flow path of the material in the tank body 20, reduces the flow dead angle, improves the stirring efficiency, helps prevent the material from depositing in the tank body 20, and maintains the fluidity of the material. When the displacement sphere 442 is in continuous contact with the first inclined surface 521, the guide arc surface 522, and the second inclined surface 523, vibration will be generated. The vibration can be transmitted to the inner wall of the tank body 20 through the guide reinforcement rod 51, and the vibration can increase the contact frequency and contact area between the materials, thereby strengthening the extraction process and mixing effect, helping to improve the mass transfer efficiency, and helping to break up aggregates or lumps in the material, especially for viscous materials or materials containing solid particles. At the same time, vibration can promote uniform dispersion of materials, and periodic vibration can prevent the deposition of materials on the wall of the tank body 20, maintain the fluidity of the materials, and vibration can reduce the accumulation of materials on the inner wall of the tank body 20, thereby reducing the need for cleaning and maintenance of the equipment.

The stirring shaft 14 is rotatably arranged on the top cover plate 23. The bottom end of the tank body 20 is provided with a bottom cover plate 25, and a heavy liquid outlet pipe 26 is provided on the bottom cover plate 25. The side walls of the tank body 20 are respectively provided with a heavy liquid inlet pipe 21 and a light liquid inlet pipe 22, and the light liquid inlet pipe 22 is arranged near the heavy liquid outlet pipe 26.

[0037] In this embodiment, during the rotation of the stirring shaft 14, the driving cylinder 11 can drive the stirring shaft 14 to be lifted, so that the stirring assembly 40 does not cooperate with the guide sleeve 50, and the stirring shaft 14 can be rotated quickly. Of course, when the stirring shaft 14 is lowered, the stirring assembly 40 cooperates with the guide sleeve 50, and the stirring shaft 14 can be rotated slowly at this time; Of course, the stirring shaft 14 can be driven by the driving cylinder 11 to reciprocate and lift, so that the stirring ring plate 30 and the stirring assembly 40 can be lifted and lowered to stir the material; When the stirring shaft 14 descends, the displacement ball 442 contacts the descending slope 54 until the displacement ball 442 is placed on the guide block 56, so as to disturb the material; Of course, the above stirring method can be selected according to actual situation.

[0038] A method for using an extraction mixing and stirring reactor dedicated to refining and chemical industry comprises the following steps: S10, feeding: The material to be stirred is introduced into the tank body 20 through the heavy liquid inlet pipe 21 and the light liquid inlet pipe 22 and the light liquid outlet pipe 24 until the material is filled in the tank body 20; S20, slow stirring: The servo motor 13 is turned on to make the stirring shaft 14 rotate slowly, driving the multiple groups of stirring ring plates 30 to rotate, and through the cooperation of the stirring assembly 40 and the guide sleeve 50, the material is driven to move in multiple directions to perform a mixing and stirring operation; S30, stirring confirmation: In S20, when the material is driven to move in multiple directions, it touches the outer surface of the tank body 20. If there is obvious vibration, it proves that the stirring assembly 40 and the guide sleeve 50 are fully matched. If there is no obvious vibration, it proves that the stirring assembly 40 and the guide sleeve 50 are not fully matched. At this time, the driving cylinder 11 is turned on to make the lifting plate 12 descend, thereby driving the stirring shaft 14 to descend until the outer surface of the tank body 20 vibrates significantly. S40, lifting and stirring: After S20 is completed, the driving cylinder 11 is turned on to drive the lifting plate 12 to lift, so that the stirring assembly 40 and the guide sleeve 50 are not fully matched, and during the lifting process of the lifting plate 12, the stirring shaft 14 keeps rotating at a slow speed, and this step is repeated at the same time, so that the stirring shaft 14 is lifted and lowered reciprocatingly to perform secondary mixing and stirring; S50, high speed stirring: After S40 is completed, when the lifting plate 12 is lifted to the highest position, the stirring assembly 40 and the guide sleeve 50 are not fully matched, and the servo motor 13 is turned on to drive the stirring shaft 14 to rotate at a high speed, driving the multiple groups of stirring ring plates 30 to rotate, and performing three mixing and stirring operations; S60, interspersed stirring: After S50 is completed, the stirring methods in S20, S40, and S50 are selected and used in combination according to the actual stirring conditions to complete the final stirring reaction process.

[0039] In this embodiment, by combining slow stirring, lifting stirring, high-speed stirring and interspersed stirring, multi-directional and multi-stage mixing of materials in the tank body 10 is achieved, thereby improving the mixing uniformity; the multi-stage stirring method increases the contact frequency and contact area between materials by combining different speeds and motion modes, thereby improving the extraction efficiency; the method allows different stirring modes to be selected for combination according to actual stirring conditions, providing operational flexibility to adapt to different stirring requirements; at the same time, the reciprocating lifting of the stirring shaft 14 during the lifting stirring process helps to prevent the material from depositing at the bottom of the tank body and maintain the fluidity of the material, and the multi-directional and multi-stage stirring helps to break the local concentration gradient in the material, promote heat exchange and mass transfer, thereby improving the reaction rate and efficiency in the refining process.
