[0044] According to the embodiment of the application, specifically: first, the bentonite raw material is mixed with a sodium agent (such as NaCl solution) in proportion, then the mixture enters the first-stage chamber 401 through the feeding valve end 500, then the inner energy-saving driving motor 800 drives the stirring shaft 405 to rotate, the inner mixing stirring structure 404 and the outer mixing stirring structure 406 are driven to rotate, the raw material in the first-stage chamber 401 is preliminarily mechanically mixed, then the frequency conversion ultrasonic generator 402 in the first-stage chamber 401 is used to vibrate at a low frequency (in the range of 20-40 kHz), and the electromagnetic induction coil 403 is used to heat, (to 50-60 DEG C), so that the bentonite primary aggregate is broken (at this time, the particle size is greater than 50 microns), and the surface impurities are stripped.

[0045] Subsequently, the material processed by the primary chamber 401 enters the secondary chamber 407 through the conical guide valve end 414, which can adjust the opening degree to control the flow rate of the material. When the material enters the secondary chamber 407, the planetary gear structure 411 is driven to rotate by the stirring shaft 405, which is connected to the secondary chamber 407. The rotation of the planetary gear structure 411 drives the secondary chamber 407 to form a reverse rotation inside the tertiary chamber 412 through the rotating ring 410, forming a shear force field. The inner disturbance breaking structure 413 rotates at high speed with the stirring shaft 405, generating turbulent flow and cavitation effect. At the same time, the variable frequency ultrasonic generator 402 in the secondary chamber 407 vibrates at medium frequency (in the range of 60-80 kHz), promoting the penetration of sodium agent into the interlayer of montmorillonite and accelerating the ion exchange reaction.

[0046] Afterwards, the material enters the migration chamber 601 from the electromagnetic discharge valve, which controls the amount of material. The opening and closing of the valve port of the electromagnetic discharge valve is controlled by the external PLC controller according to the real-time sodium degree. The tertiary chamber 412 is connected to the high-speed magnetic particle generator 602 through the back end, which supplements the surface carboxylated Fe3O4 nanoparticles (particle size in the range of 15-20 nm) in real time. After the action of the directional migration assembly 600, the material falls into the tertiary chamber 412 from the discharge valve port 604 for operation. Due to the reverse rotation of the secondary chamber 407 inside the tertiary chamber 412, the first meshing breaking structure 408 and the second meshing breaking structure 409 are engaged with each other, further breaking the particles (in the range of 20-30 μm) and stripping the Ca²⁺ and montmorillonite complex on the surface of the particles. In combination with the variable frequency ultrasonic generator 402, the Ca²⁺ and montmorillonite complex on the surface of the particles are stripped by high-frequency ultrasonic operation (in the range of 100-120 kHz). Then the material is discharged from the discharge valve end 417, and the magnetic particles are recycled and reused through the gradient magnetic field.

[0047] The whole device realizes efficient modification from raw material pretreatment to finished product output through the cooperation of multiple components. First, the raw material is mixed with the sodium agent and enters the first chamber 401, and the mechanical stirring and low-frequency ultrasonic crushing of the agglomerates create conditions for ion exchange. Then the material enters the second chamber 407, and the planetary gear structure 411 drives the second chamber 407 to rotate reversely to form a shear force field, which, together with the intermediate-frequency ultrasonic and internal turbulent flow crushing structure 413, promotes the penetration of the sodium agent and accelerates the ion exchange. Then the material enters the migration chamber 601, and the high-speed magnetic particle generator 602 sprays nano-particles to adsorb Ca²⁺, and the magneto-electric field coupling generator 607 drives the directional migration of the composite ion pair to complete the deep exchange. Finally, the material enters the third chamber 412, and the high-frequency ultrasonic peeling removes the water 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 sodium reaction time, increases the sodium degree, and simultaneously reduces energy consumption and raw material cost, and has a high magnetic particle recovery rate, which improves the product uniformity and performance stability of bentonite efficient modification.
