Description

Technical Field

[0001] The present invention relates to the technical field of bentonite production, in particular to a sodium modification treatment system and process used in bentonite production. Background Art

[0002] Bentonite is a non-metallic mineral with montmorillonite as its main mineral component. The montmorillonite structure is a 2:1 type crystal structure consisting of two silicon-oxygen tetrahedra sandwiched by a layer of aluminum-oxygen octahedron. Due to the presence of certain cations in the layered structure formed by the montmorillonite unit cell, and the fact that these cations interact with the montmorillonite unit cell very unstablely and are easily exchanged by other cations, it has good ion exchange properties.

[0003] However, in the prior art, such as the "fully automatic processing equipment and method for sodium modified bentonite" in China Publication No. CN116688801A, a water replenishing device, a fixed plate, a processing box, a first motor, a main uniform stirring wheel, a mobile stirring and mixing device, an output frame, a second motor and a sealing baffle, the fixed plate is fixedly connected to both sides of the bottom of the processing box, the first motor is fixedly connected to the middle outer side of the processing box, the water replenishing device is fixedly connected to the upper end of the processing box, the main uniform stirring wheel is rotatably installed in the middle of the bottom end of the processing box, and the mobile stirring and mixing device is arranged inside the processing box. By setting a water replenishing device, the water replenishing device can be used to replenish the water of the bentonite in the processing box in real time, and the rotating main uniform stirring wheel can improve the efficiency of the bentonite in adjusting the water content of the original ore. By setting a mobile stirring and mixing device, the two stirring adjustment devices in the mobile stirring and mixing device can automatically reciprocate inside the processing box to accelerate the mixing of the bentonite and the sodium agent, so that the bentonite and the sodium agent are evenly mixed, and the rotating column and the auxiliary rotating stirring rod inside the stirring adjustment device rotate during the movement, which plays a role in accelerating the mixing, so that the sodium modification effect of the bentonite is good, and the efficiency is high, saving time and effort.

[0004] At present, in the sodium modification process of bentonite production, although traditional stirring devices (such as the above-mentioned device) improve mixing uniformity, the "water-proof membrane" on the surface of the bentonite particles still hinders the penetration of Na+, resulting in the sodium modification reaction only occurring on the surface of the particles, causing incomplete sodium modification and severely limited product performance. In other words, the Ca²⁺ between the montmorillonite layers cannot be fully replaced by Na⁺, and the CEC value of the modified bentonite cannot effectively reach the ideal value, which will directly affect its key properties such as adsorption and swelling. In addition, the surface reaction mode makes the sodium modification time long and the utilization rate insufficient, which leads to high overall energy consumption and increased raw material costs. Therefore, it is necessary to propose a sodium modification treatment system and process for bentonite production. Summary of the Invention

That is, the Ca²⁺ between the montmorillonite layers cannot be fully replaced by Na⁺, and the CEC value of the modified bentonite cannot effectively reach the ideal value, which will directly affect its key properties such as adsorption and expansibility.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] In the embodiment of the present invention, referring to Figure 1 、 Figure 2 and Figure 6 As shown: A sodium modification treatment system for bentonite production includes a three-stage ultrasonic mixing chamber component 400 and a directional migration component 600 installed therein. The three-stage ultrasonic mixing chamber component 400 is used to break up bentonite particle agglomerates, peel off the surface water-isolating film, and promote ion exchange reactions through gradient ultrasonic vibration. The directional migration component 600 is used to target the adsorption of Ca²⁺ through magnetic particles and drive the directional migration of ions by coupling the magnetic field and electric field.

[0021] In some embodiments, according to Figure 1-Figure 7As shown, the three-stage ultrasonic mixing chamber assembly 400 includes a primary chamber 401, a secondary chamber 407 and a tertiary chamber 412. Electromagnetic induction coils 403 and variable frequency ultrasonic generators 402 are respectively installed in the internal cavity spaces of the primary chamber 401, the secondary chamber 407 and the tertiary chamber 412. The variable frequency ultrasonic generators 402 are respectively set to low frequency, medium frequency and high frequency action modes.

[0022] The three-stage ultrasonic mixing chamber assembly 400 further includes an internal mixing and stirring structure 404 and an external mixing and stirring structure 406. The internal mixing and stirring structure 404 and the external mixing and stirring structure 406 are both connected with a stirring shaft 405. The internal mixing and stirring structure 404 and the external mixing and stirring structure 406 are arranged inside the first-stage chamber 401, and a conical guide valve end 414 is installed at the side end of the first-stage chamber 401.

[0023] A rotating groove is provided on the outer wall surface of the conical guide valve end 414, and the internal rotation of the rotating groove is connected to a rotating ring 410, and the outside of the rotating ring 410 is connected to the secondary chamber 407. A planetary gear structure 411 is installed inside the side end of the secondary chamber 407. The planetary gear structure 411 is synchronously installed on the outside of the stirring shaft 405 and is connected to the inner wall of the secondary chamber 407, and is used to drive the secondary chamber 407 to form a reverse rotation inside the tertiary chamber 412. The side end of the primary chamber 401 is connected to the feed valve end 500.

[0024] A first meshing crushing structure 408 is installed on the outer surface of the secondary chamber 407, an internal turbulence crushing structure 413 is installed inside the secondary chamber 407, and the internal turbulence crushing structure 413 is synchronously installed on the outside of the stirring shaft 405. A second meshing crushing structure 409 is installed around the inner wall surface of the tertiary chamber 412, and the side end of the secondary chamber 407 and the migration chamber 601 are connected through an electromagnetic discharge valve.

[0025] A stator and rotor structure 700 is installed at the side end of the tertiary chamber 412, and the interior of the stator and rotor structure 700 and the exterior of the stirring shaft 405 are nested. An energy-saving drive motor 800 is installed at the side end of the stirring shaft 405, and a pulley structure 300 is installed on the outside of the output end of the energy-saving drive motor 800. An electromagnetic blocker is installed at the connecting end of the pulley structure 300 and the output end of the energy-saving drive motor 800. When the secondary chamber 407 rotates in the reverse direction inside the tertiary chamber 412, the electromagnetic blocker can be used to connect the pulley structure 300 and the output end of the energy-saving drive motor 800, and then the pulley structure 300 drives the drive gear 416 to rotate, and then the drive gear 416 and the annular tooth edge 415 are meshed and connected, and the annular tooth edge 415 is used to drive the tertiary chamber 412 to rotate clockwise, so that the tertiary chamber 412 and the secondary chamber 407 rotate in different directions, so that the first meshing crushing structure 408 and the second meshing crushing structure 409 are meshed with each other to further crush the particles.

[0026] The top output end of the pulley structure 300 is connected to a driving gear 416, and a ring tooth edge 415 is installed around the outer wall surface of the tertiary chamber 412. The driving gear 416 and the ring tooth edge 415 are meshed and connected. The bottom end of the tertiary chamber 412 is connected to a discharge valve end 417, and the back end of the tertiary chamber 412 is engaged with the high-speed magnetic particle generator 602 for actively replenishing materials into the high-speed magnetic particle generator 602.

[0027] A connecting frame is installed on the outside of the energy-saving drive motor 800, and angle adjustment cylinders 200 are installed on the left and right ends of the connecting frame. The outside of the connecting frame is rotatably connected to the support structure 100. When the whole is operating, the angle adjustment cylinder 200 drives the three-stage ultrasonic mixing chamber component 400 and the directional migration component 600 to form angle adjustment.

[0028] According to an embodiment of the present invention, specifically: first, the bentonite raw material and the sodium-forming agent (such as NaCl solution) are mixed in proportion, and then enter the primary chamber 401 through the feed valve end 500. Then, the internal energy-saving drive motor 800 drives the stirring shaft 405, driving the internal mixing and stirring structure 404 and the external mixing and stirring structure 406 to rotate, thereby performing preliminary mechanical mixing of the raw materials inside the primary chamber 401. Then, the variable frequency ultrasonic generator 402 in the primary chamber 401 is used to vibrate at a low frequency (in the range of 20-40 kHz) and cooperate with the electromagnetic induction coil 403 to heat the raw materials (heated to 50-60°C), thereby breaking up the primary agglomerates of the bentonite (at this time, making its particle size greater than 50 μm) and removing surface impurities.

[0029] Subsequently, the material processed in the primary chamber 401 enters the secondary chamber 407 through the conical guide valve end 414, wherein the conical guide valve end 414 can adjust the opening to control the material flow rate. When the material enters the secondary chamber 407, the stirring shaft 405 synchronously drives the planetary gear structure 411 to rotate. Since the planetary gear structure 411 and the secondary chamber 407 are connected, the rotation of the planetary gear structure 411 is used to drive the secondary chamber 407 to form a counter-rotation inside the tertiary chamber 412 through the rotating ring 410, forming a shear force field, and causing the internal turbulence and fragmentation structure 413 to rotate at high speed with the stirring shaft 405, generating turbulence and cavitation effects. At the same time, the variable frequency ultrasonic generator 402 in the secondary chamber 407 vibrates at a medium frequency (in the range of 60-80kHz), promoting the penetration of the sodium agent into the montmorillonite interlayer and accelerating the ion exchange reaction.

[0030] Afterwards, the material enters the migration chamber 601 through the electromagnetic discharge valve, and the material quantity is controlled. The opening and closing of the electromagnetic discharge valve is controlled in real time by an external PLC controller according to the sodium content. The tertiary chamber 412 is connected to the high-speed magnetic particle generator 602 through the back side, and the surface carboxylated Fe3O4 nanoparticles (particle size is in the range of 15-20nm) are replenished in real time. After the action of the directional migration component 600, the material falls from the discharge valve port 604 into the tertiary chamber 412 for operation. And because the secondary chamber 407 is in the tertiary chamber The reverse rotation inside chamber 412 causes the first meshing crushing structure 408 and the second meshing crushing structure 409 to engage with each other, further crushing the particles (in the range of 20-30μm) and stripping the Ca²⁺ and montmorillonite complex on the particle surface. The variable frequency ultrasonic generator 402 operates with high-frequency ultrasonic waves (in the range of 100-120kHz) to strip the Ca²⁺ and montmorillonite complex on the particle surface. The material is then discharged from the discharge valve end 417, and the magnetic particles are recycled through the gradient magnetic field.

[0031] The overall system achieves efficient modification from raw material pretreatment to finished product output through the coordinated operation of multiple components. First, the raw materials are mixed with the sodium-forming agent and enter the primary chamber 401. Mechanical stirring and low-frequency ultrasound break up the agglomerates, creating conditions for ion exchange. The material then enters the secondary chamber 407. The planetary gear structure 411 drives the secondary chamber 407 to rotate in the opposite direction to form a shear force field. Combined with the medium-frequency ultrasound and the internal turbulent flow breaking structure 413, it promotes the penetration of the sodium-forming agent and accelerates ion exchange. The material then enters the migration chamber 601, and the high-speed magnetic particle generator 602 sprays nanoparticles. After adsorbing Ca²⁺, the magneto-electric field coupling generator 607 drives the directional migration of the composite ion pairs to complete deep exchange. Finally, the material enters the tertiary chamber 412, where high-frequency ultrasound peels off the water-proof film on the surface of the particles. The finished product is discharged through the discharge valve end 417, and the magnetic particles are recycled through the gradient magnetic field. The device shortens the sodiumization reaction time and achieves a high degree of sodiumization through the multi-field coordination of three-stage gradient ultrasonic crushing, reverse rotation shearing, and magneto-electric coupling migration. It simultaneously achieves reduced energy consumption and raw material costs, and has a high recovery rate of magnetic particles, which improves the uniformity and performance stability of the product for efficient modification of bentonite.

[0032] In some embodiments, according to Figure 7-10 As shown, the directional migration component 600 includes a migration chamber 601, a high-speed magnetic particle generator 602 and a magneto-electric field coupling generator 607. The high-speed magnetic particle generator 602 is composed of a double-cone swirl atomizing nozzle and a Venturi accelerator, which is used to spray surface carboxyl-modified nanoparticles between montmorillonite layers to form magnetic particle and Ca²⁺ composite ion pairs. The high-speed magnetic particle generator 602 is equally divided and arranged around the surface of the migration chamber 601, with its output end aligned with the internal area of the migration chamber 601. The magneto-electric field coupling generator 607 is used to drive the directional migration of ions through magneto-electric coupling.

[0033] The directional migration component 600 is installed at the connecting guide connection between the secondary chamber 407 and the tertiary chamber 412. The directional migration component 600 further includes a guide ring 603, which is located at the connecting end of the secondary chamber 407 and the migration chamber 601 and is used to guide and control the amount of material. A shielding plate 606 is installed inside the migration chamber 601, and miniature electromagnetic guide rods 605 are symmetrically installed on the top and bottom of the shielding plate 606 to drive the relative displacement adjustment of the shielding plate 606. A discharge valve port 604 is opened on the bottom surface of the migration chamber 601.

[0034] A driving guide rail 608 is installed on the surface of the shielding plate 606, and the side end of the driving guide rail 608 is slidingly connected to a one-way electromagnetic field control seat 612. A magnetic-electric field integrated detection sensor 611 is installed inside the one-way electromagnetic field control seat 612. The magnetic-electric field coupling generator 607 is installed at the side end of the one-way electromagnetic field control seat 612, and is independently controlled and driven by the one-way electromagnetic field control seat 612. A micro driver 609 is installed at the other end of the driving guide rail 608, and the output end of the micro driver 609 is connected to a flexible transmission rod 610. The micro driver 609 drives the one-way electromagnetic field control seat 612, the magnetic-electric field integrated detection sensor 611, and the magnetic-electric field coupling generator 607 to form displacement adjustment outside the driving guide rail 608 through the flexible transmission rod 610.

[0035] According to an embodiment of the present invention, more specifically: first, the material processed in the secondary chamber 407 enters the migration chamber 601 through the electromagnetic discharge valve, and the guide ring 603 located at the connection end controls the material flow through an annular slit (such as an adjustable width) to ensure that the bentonite particles enter the reaction area in a monodisperse state to avoid agglomeration and blockage. The shielding plate 606 in the migration chamber 601 is symmetrically arranged and controlled by the micro electromagnetic guide rod 605, so that the micro electromagnetic guide rod 605 can drive the shielding plate 606 and the structure on the surface of the shielding plate 606 to perform displacement adjustment.

[0036] Then, multiple sets of high-speed magnetic particle generators 602 surround the migration chamber 601 at intervals of 30°-60°. Their double-cone swirl atomizing nozzles mix the surface carboxyl-modified Fe3O4 nanoparticles (particle size 15-20nm) with the dispersion. After being accelerated by the Venturi accelerator, they are sprayed at supersonic speed to the center of the migration chamber 601. The high-speed particle flow forms an umbrella-shaped spray area, covering the entire migration chamber 601, so that the carboxyl groups on the particle surface and the Ca²⁺ between the montmorillonite layers are combined through coordination bonds, forming a composite ion pair of magnetic particles and Ca²⁺. The adsorption process is completed within 0.1 seconds, ensuring the effective capture of the interlayer Ca²⁺. The magnetic field coupling generator 60 7 is integrated into the unidirectional electromagnetic field control base 612. By driving the guide rail 608 to slide to the preset position, the magnetic field generating unit (such as a three-axis Helmholtz coil) generates a gradient magnetic field, and the electric field generating unit (such as a parallel plate electrode) applies a high-frequency alternating electric field. The phase difference between the two is automatically calibrated to 45°, forming a spiral composite force field. Under the synergistic action of the Lorentz force (magnetic field drive) and the dielectrophoretic force (electric field drive), the composite ion pairs migrate along the magnetic field gradient direction toward the bottom of the migration chamber 601. During this process, Na⁺ enters the montmorillonite interlayer from the solution, completing the Ca²⁺ replacement. The migration path covers the entire space of the migration chamber 601, ensuring deep ion exchange.

[0037] In addition, the above-mentioned micro-electromagnetic guide rod 605 can fine-tune the angle of the shielding plate 606 in real time (the angle range is controlled within 0-15°) based on the data of the magnetic-electric field integrated detection sensor 611, thereby optimizing the area of action of the particle flow and the composite field. For example, when it is detected that the sodium content in a certain area is insufficient, the shielding plate 606 is tilted to guide the material to remain, thereby extending the reaction time. The micro-actuator 609 slides the one-way electromagnetic field control seat 612 through the flexible transmission rod 610 to adjust the spatial position of the magnetic-electric field coupling generator 607 to ensure the uniformity of the field strength in the migration chamber 601. The magnetic-electric field integrated detection sensor 611 monitors the magnetic field strength and electric field frequency in real time, and automatically compensates for the deviation through an external PLC controller. The bentonite particles that have completed ion exchange enter the third-level chamber 412 through the discharge valve port 604 at the bottom of the chamber. The valve port opening is automatically adjusted according to the particle size of the material to avoid premature discharge of unreacted particles.

[0038] The annular slit of the guide ring 603 is adjusted to ensure that the material enters the migration chamber 601 in a monodispersed state, avoiding particle agglomeration and blockage. The dynamic inclination adjustment (0-15°) of the shielding plate 606 intelligently divides the injection zone and the reaction zone, minimizing the error in material residence time. This creates uniform flow conditions for targeted adsorption and field-effect driving, ensuring reaction consistency from the source. Furthermore, multiple sets of high-speed magnetic particle generators 602 use double-cone cyclonic atomization and Venturi acceleration technology to spray surface carboxyl-modified nanoparticles at supersonic speeds into the center of the chamber, forming an umbrella-shaped particle flow that covers the entire space. Within 0.1 seconds, the Ca²⁺ between the montmorillonite layers is efficiently captured through coordination bonds (adsorption efficiency ≥ 95%), breaking through the shallow limitations of traditional stirred adsorption and achieving difficult migration. The deep capture of ions lays the foundation for deep ion exchange. At the same time, the magnetic-electric field coupling generator 607 constructs a spiral composite force field. Through the synergistic effect of the Lorentz force and the dielectrophoretic force, it drives the three-dimensional directional migration of the composite ion pairs of magnetic particles and Ca²⁺. The path covers the entire chamber space, the migration rate is improved, the sodium reaction time is shortened, and the sodium degree is stable and high. This completely solves the problem of incomplete modification caused by only surface reaction in traditional processes. The magnetic-electric field integrated detection sensor 611 monitors the field strength and sodium degree in real time, and links the micro-electromagnetic guide rod 605 and the micro-driver 609 to dynamically adjust the angle of the shielding plate 606 and the position of the magnetic-electric field to ensure that the field strength uniformity has a small deviation. When the local reaction is insufficient, the residence time is automatically extended, which reduces the overall energy consumption and cost.
