Description

Technical Field

[0001] This invention relates to the field of electroosmotic drying and mixing technology, and in particular to an electroosmotic drying mixer and its method of use. Background Technology

[0002] In electroosmotic drying mixing technology, materials such as macroporous silica gel, polyvinyl alcohol water-soluble curing agent, molecular sieve, activated alumina and graphene are usually preferred. By mixing them to form fluid adsorbent materials, improving the mixing efficiency of the adsorbent materials is crucial to the electroosmotic dehumidification capacity. Therefore, the research on fluid mixing efficiency technology of micro mixers has become one of the hot topics in the theoretical research of microfluidic systems.

[0003] At the microscale, the flow of fluid adsorbent materials is typically highly ordered laminar flow, lacking turbulence; therefore, diffusion is the primary mechanism for mixing. Small molecules (i.e., rapidly diffusing substances) can achieve diffusion mixing over distances of tens of micrometers within seconds, but the equilibrium time required for macromolecules such as macroporous silica gel, water-soluble polyvinyl alcohol curing agents, and molecular sieves to mix over the same distance can range from several minutes to several hours.

[0004] For electroosmotic drying, excessively long mixing times are impractical. In practical applications, improving the mixing efficiency of adsorbent materials is crucial. Therefore, a more rationally structured solution is urgently needed to control the electrode field strength and frequency on the outer wall of the electroosmotic mixer, thereby improving mixing efficiency. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is that the moving parts in the active mixer are very thin at the microscale, resulting in low mixing efficiency.

[0006] The above-mentioned technical problems are solved by the following technical solutions:

[0007] This invention proposes an electroosmotic drying mixer, which includes a mixer, a titanium alloy electrode assembly, a vibratory viscometer, and a control host.

[0008] In a preferred embodiment of the electroosmotic drying mixer of the present invention: the mixer has a storage chamber formed inside;

[0009] At least two pairs of titanium alloy electrode groups are disposed on the outer wall of the mixer;

[0010] A vibration viscometer, installed in the storage chamber, is used to detect the viscosity of the fluid adsorbed material in the storage chamber in real time; and,

[0011] The control host is electrically connected to the vibratory viscometer and the titanium alloy electrode assembly. The control host receives the viscosity signal from the vibratory viscometer, compares the viscosity signal with a set threshold to determine the mixing efficiency, and adjusts the intensity and frequency of the alternating electric field applied to the titanium alloy electrode assembly based on the mixing efficiency through an adaptive algorithm.

[0012] In a preferred embodiment of the electroosmotic drying mixer of the present invention: the adaptive algorithm built into the control host is a proportional-integral-derivative control algorithm, wherein the error signal of the control algorithm is the difference between the set target viscosity and the actual viscosity detected in real time by the vibratory viscometer.

[0013] In a preferred embodiment of the electroosmotic drying mixer of the present invention: when the fluid viscosity detected by the vibratory viscometer is lower than the set threshold, the control host determines that the mixing efficiency is too low and automatically increases the intensity and frequency of the electric field applied to the titanium alloy electrode assembly.

[0014] In a preferred embodiment of the electroosmotic drying mixer of the present invention: the storage chamber is provided with a fluid adsorption material, which includes macroporous silica gel, polyvinyl alcohol water-soluble curing agent, molecular sieve, activated alumina and graphene.

[0015] In a preferred embodiment of the electroosmotic drying mixer of the present invention: the control host includes a main control module and an electrode drive module.

[0016] In a preferred embodiment of the electroosmotic drying mixer of the present invention: the main control module is used to receive the viscosity signal from the vibratory viscometer and run the adaptive algorithm;

[0017] The electrode driving module is used to drive the titanium alloy electrode assembly according to the instructions of the main control module.

[0018] In a preferred embodiment of the electroosmotic drying mixer of the present invention: the surface of the titanium alloy electrode assembly is covered with a ceramic insulating coating.

[0019] In a preferred embodiment of the electroosmotic drying mixer of the present invention: the ceramic insulating coating is alumina or zirconium oxide, and the coating thickness is 30–40 micrometers.

[0020] The present invention also proposes a method for using an electroosmotic drying mixer, which includes a basic mixing stage, a real-time monitoring stage, a judgment and decision-making stage, and an adaptive adjustment stage.

[0021] In a preferred embodiment of the method of using the electroosmotic drying mixer of the present invention: the viscosity of the fluid adsorbent material in the storage chamber is detected in real time using a vibratory viscometer;

[0022] The control host drives the titanium alloy electrode group through the electrode drive module to generate an alternating electric field to mix the fluid adsorbed material in the storage chamber;

[0023] The main control module inside the control unit compares the received fluid viscosity with a set threshold, and automatically increases the intensity and frequency of the alternating electric field when the fluid viscosity is detected to be lower than the set threshold, so as to improve the mixing efficiency.

[0024] In a preferred embodiment of the method of using the electroosmotic drying mixer of the present invention: the step of automatically enhancing the intensity and frequency of the alternating electric field by means of a proportional-integral-derivative control algorithm is realized. The control algorithm uses the difference between a set target viscosity and the real-time detected fluid viscosity as an error signal to generate a control output for adjusting the electric field intensity and frequency.

[0025] The beneficial effects of this invention are as follows: It solves the problem of low efficiency in traditional mixers. It employs a closed-loop control system that uses a built-in vibratory viscometer to detect fluid viscosity in real time. When the viscosity falls below a set threshold, the adaptive algorithm of the control unit automatically increases the intensity and frequency of the electric field applied to the electrodes, generating a chaotic flow field through electroosmosis, thereby significantly improving mixing efficiency.

[0034] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0035] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0036] Example 1, referring to Figure 1 This embodiment provides an electroosmotic drying mixer, including a mixer 1, at least two pairs of titanium alloy electrode groups 2, a vibratory viscometer 3, and a control host 4.

[0037] The mixer 1 is the main body of the device and can be made of corrosion-resistant materials such as Hastelloy C-276 or titanium alloy Ti-6Al-4V. Inside it, a storage chamber 11 is formed to contain the working medium.

[0038] Titanium alloy electrode assembly 2 is symmetrically embedded on the outer wall of mixer 1. The surface of electrode assembly 2 is uniformly covered with a ceramic insulating coating with a thickness of 30–40 micrometers by plasma spraying or sputtering deposition technology.

[0039] The titanium alloy electrode group 2 includes a first titanium alloy electrode group positive electrode 21, a first titanium alloy electrode group negative electrode 22, a second titanium alloy electrode group positive electrode 23, and a second titanium alloy electrode group negative electrode 24, all of which are electrically connected to the control host 4.

[0040] The coating material can be alumina (Al2O3) or zirconium oxide (ZrO2). Its function is to ensure the insulation and safety of the electrodes while ensuring that the electric field can effectively penetrate the container wall and act on the internal fluid.

[0041] The vibratory viscometer 3 is fixedly installed inside the storage chamber 11 of the mixer 1. It is a sensor used to continuously monitor the viscosity of the fluid adsorbed material in the storage chamber 11, and at the same time, it converts the measurement results into an electrical signal and outputs it to the control host 4.

[0042] The control host 4 is located on one side of the mixer 1 and is connected to the vibratory viscometer 3 inside the mixer 1 and the titanium alloy electrode assembly 2 outside the mixer 1 via a programmable cable. The control host 4 integrates a proportional-integral-derivative PID control algorithm, which can process sensor signals and issue control commands, thus forming a complete closed-loop feedback control system.

[0043] During operation, the control unit 4 drives the titanium alloy electrode assembly 2 to generate a preset alternating electric field. This electric field induces a spiral chaotic flow field in the fluid within the storage chamber 11 through the electroosmotic effect. This disordered flow driven by the electric field can effectively break the ordered laminar flow state of the fluid at the microscale, achieving more efficient macroscopic mixing than traditional diffusion mixing. Simultaneously, the vibratory viscometer 3 within the storage chamber 11 operates continuously, measuring the overall viscosity of the fluid adsorbed material in real time and continuously sending this viscosity signal to the control unit 4.

[0044] After receiving the viscosity signal, the control host 4 compares it with a pre-set target viscosity threshold. Fluid viscosity is used as an indirect indicator of mixing efficiency. Typically, when two or more components are mixed more uniformly, the macroscopic viscosity of the resulting colloidal or suspension system changes specifically; in this case, it increases. Therefore, when the host determines that the detected actual viscosity is lower than the set threshold, it considers the current mixing efficiency to be substandard. Once the mixing efficiency is determined to be low, the built-in PID algorithm of the control host 4 is immediately triggered. The PID algorithm automatically calculates the adjustment amount u(t) based on the difference between the current viscosity and the target viscosity, i.e., the error signal e(t), and outputs a command accordingly to dynamically increase the intensity and frequency of the alternating electric field applied to the titanium alloy electrode assembly 2.

[0045] The enhanced electric field generates a stronger electroosmotic effect and a more intense chaotic flow field, thereby further improving mixing efficiency. This increased mixing efficiency leads to a rise in fluid viscosity. The vibratory viscometer 3 feeds back the new viscosity value to the control unit 4, which then compares and adjusts it again. This process repeats continuously, forming a dynamic, automatic closed-loop control until the fluid viscosity stabilizes near the set target value, ensuring a highly uniform final mixture and solving the problem of low efficiency in traditional mixers due to a lack of real-time feedback.

[0046] Example 2, refer to Figure 1 This embodiment is based on the previous embodiment and provides an electroosmotic drying mixer, including a mixer 1, a titanium alloy electrode group 2, a vibratory viscometer 3 and a control host 4.

[0047] The mixer 1 is the main body of the device and can be made of corrosion-resistant materials such as Hastelloy C-276 or titanium alloy Ti-6Al-4V. Inside it, a storage chamber 11 is formed to contain the working medium.

[0048] The storage chamber 11 is pre-filled with a fluid adsorption material, which is a functional mixture composed of macroporous silica gel, polyvinyl alcohol as a water-soluble curing agent, molecular sieve, activated alumina, and graphene.

[0049] The titanium alloy electrode assembly 2 is symmetrically embedded on the outer wall of the mixer 1. The surface of the electrode assembly 2 is uniformly covered with a ceramic insulating coating with a thickness of 30–40 micrometers by plasma spraying or sputtering deposition technology to achieve precise electric field control and ensure safety.

[0050] The ceramic insulating coating is preferably alumina (Al2O3) or zirconium oxide (ZrO2). Its function is to ensure the insulation and safety of the electrode while ensuring that the electric field can effectively penetrate the wall of the device and act on the internal fluid. The thickness is preferably between 30 and 40 micrometers to achieve the best balance between insulation performance and electric field penetration efficiency.

[0051] The vibratory viscometer 3 is fixedly installed inside the storage chamber 11 of the mixer 1. It is a sensor used to continuously monitor the viscosity of the fluid adsorbed material in the storage chamber 11, and at the same time, it converts the measurement results into an electrical signal and outputs it to the control host 4.

[0052] The control host 4 is located on one side of the mixer 1 and is connected to the vibratory viscometer 3 inside the mixer 1 and the titanium alloy electrode assembly 2 outside the mixer 1 via a programmable cable. The control host 4 integrates a proportional-integral-derivative PID control algorithm, which can process sensor signals and issue control commands, thus forming a complete closed-loop feedback control system.

[0053] The control host 4 includes an intelligent main control module 41 and an electrode drive module 42. The intelligent main control module 41 is electrically connected to the electrode drive module 42. The intelligent main control module 41 provides frequency control signals, and the electrode drive module 42 provides alternating electric field strength.

[0054] The titanium alloy electrode group 2 includes a first titanium alloy electrode group positive electrode 21, a first titanium alloy electrode group negative electrode 22, a second titanium alloy electrode group positive electrode 23, and a second titanium alloy electrode group negative electrode 24, all of which are electrically connected to the electrode drive module 42 of the control host 4.

[0055] In use, the vibratory viscometer 3 measures the viscosity of the fluid material in real time and transmits the electrical signal representing the viscosity precisely to the intelligent main control module 41 of the control host 4. The intelligent main control module 41 has a built-in proportional-integral-derivative (PID) control algorithm. It compares the received actual viscosity value with a preset "target viscosity value" and calculates the difference between the two, i.e., the error signal e(t). The module 41 continuously judges whether the actual viscosity is lower than a key "set threshold". Once it is lower than the threshold, the system determines that the mixing efficiency is insufficient. The PID algorithm performs proportional, integral, and derivative operations based on the magnitude and trend of the error signal e(t) to generate a precise control signal for adjusting the electric field strength and frequency.

[0056] The control signal generated by the intelligent main control module 41 is sent to the electrode drive module 42. The drive module 42 functions as a power amplifier, amplifying the weak control signal from the main control module 41 and converting it into high-power alternating current sufficient to drive the titanium alloy electrode assembly 2.

[0057] The titanium alloy electrode assembly 2 generates an alternating electric field of specific intensity and frequency under drive. This electric field penetrates the ceramic insulating coating and the wall of the mixer 1, inducing a stronger chaotic flow in the internal fluid, thereby significantly improving the mixing efficiency. The increased efficiency causes a change in the fluid viscosity. This new viscosity value is captured by the vibratory viscometer 3 and sent back to the intelligent main control module 41, forming a complete, accurate, and efficient PID closed-loop control until the error signal e(t) approaches zero, that is, the actual viscosity reaches the target viscosity.

[0058] Example 3, referring to Figure 1 This embodiment provides a method for using an electroosmotic drying mixer, applicable to the electroosmotic drying mixers of Embodiments 1 and 2, including a basic mixing stage, a real-time monitoring stage, a judgment and decision-making stage, and an adaptive adjustment stage.

[0059] In the basic mixing stage, the fluid adsorbent material to be mixed is loaded into the storage chamber 11 of the mixer 1. This material is a functional mixture containing macroporous silica gel, polyvinyl alcohol water-soluble curing agent, molecular sieve, activated alumina and graphene. Then, the control host 4 sets a "target viscosity threshold" to determine whether the mixing is complete according to the process requirements.

[0060] The intelligent main control module 41 of the control host 4 issues an initial command, driving the titanium alloy electrode group 2 through the electrode drive module 42 to apply an alternating electric field of basic strength and frequency. This electric field penetrates the ceramic insulating coating and the container wall, inducing electroosmosis in the fluid in the storage chamber 11, forming a chaotic flow field, and initiating preliminary mixing of the materials. This disordered flow driven by the electric field can effectively break the ordered laminar flow state of the fluid at the microscale, achieving more efficient macroscopic mixing than traditional diffusion mixing. The electric field strength and frequency can be adjusted in real time based on fluid viscosity data, and the electrode strength and frequency are automatically increased when a decrease in mixing efficiency is detected, solving the problem of low mixing efficiency in traditional mechanical stirring mixers.

[0061] During the real-time monitoring phase, while mixing, the vibratory viscometer 3 in the storage chamber 11 works continuously to measure the overall viscosity of the fluid adsorbed material in real time, and continuously sends this viscosity signal to the intelligent main control module 41 of the control host 4.

[0062] During the decision-making phase, after receiving the viscosity signal, the intelligent main control module 41 of the control host 4 compares it with a pre-set target viscosity threshold. Fluid viscosity is used as an indirect indicator of mixing efficiency. Typically, when two or more components are mixed more uniformly, the macroscopic viscosity of the resulting colloidal or suspension system will change in a specific way; in this scheme, it will increase. Therefore, when the host determines that the detected actual viscosity is lower than the set threshold, it considers that the current mixing efficiency has not met the target.

[0063] During the adaptive adjustment phase, when the mixing efficiency is determined to be low, the PID algorithm built into the control host 4 is immediately triggered. The PID algorithm automatically calculates the adjustment amount u(t) based on the difference between the current viscosity and the target viscosity, i.e., the error signal e(t), and outputs a command accordingly. This command is then executed by the electrode drive module 42 to dynamically increase the intensity and frequency of the alternating electric field applied to the titanium alloy electrode group 2.

[0064] In this embodiment, the intelligent main control module 41 circuit uses the AT32F403ACGT7 as the signal control chip. This chip is based on the ARM Cortex-M4 core and is designed specifically for applications requiring real-time control. The core uses the ARM Cortex-M4, supporting DSP instructions and a floating-point unit (FPU). With a main frequency of up to 240MHz, it provides powerful computing capabilities, suitable for complex algorithms and real-time control tasks. Its high main frequency, large memory, and rich peripherals strike a balance between performance and cost, making it a preferred alternative to the traditional STM32F4 series. The 3.3V required by the chip is provided by an external power supply, and the specific flow of the control signals is as follows:

[0065] Viscosity signal acquisition: The output signal of the vibratory viscometer is input to the main control chip AT32F403ACGT7.

[0066] Control signal output: The main control chip outputs the control signal SIGNAL through pin 27 of the built-in digital-to-analog converter (DAC).

[0067] The electrode drive module uses a CA-IS3211 isolated gate driver, which amplifies the SIGNAL control signal on pin 27 and outputs the AC+ signal to drive the titanium alloy electrode group.

[0068] The control host 4 generates an alternating electric field, causing the two pairs of titanium alloy electrode groups (2) to generate a periodic electric field. Through the electroosmotic effect, the charged particles of the fluid in the mixer form a spiral chaotic flow field under the drive of the alternating electric field, significantly breaking the traditional laminar boundary layer. The control host has a built-in adaptive algorithm, which adopts the proportional-integral-derivative (PID) control algorithm, and its mathematical formula is as follows:

[0071] u(t): Control output (adjustment amount of electric field strength and frequency).

[0073] K p ,K i ,K d : PID controller parameters (need to be optimized based on experimental data).

[0074] In this embodiment, please refer to the appendix. Figure 4 The electrode drive module circuit uses CA-IS3211 as the driver chip, and the input signal SIGNAL of this driver chip is provided by the attached... Figure 3 Pin 27 of the chip is provided. This chip is an optocoupler-compatible single-channel isolated gate driver that can provide a 5A pull-up / 6A sink output peak current capability. A supply voltage range of up to 30V allows for effective signal drive. Key performance features of this chip include high common-mode transient immunity (CMTI), low propagation delay, and low pulse width distortion. An external adjustable resistor PR1 can be used to adjust the electric field strength of the electrodes.

[0075] In this embodiment, referring to Figure 5, to study the effect of alternating electric field electroosmosis on enhancing fluid mixing within the microchannel, the mixing of fluids within the microchannel was simulated when the applied alternating electric field was a sinusoidal field.

[0076] Among them, the sinusoidal electric field:

[0077] E(t)=E0sin(ωt)

[0078] (Where, ω = 2πf, f = 50Hz)

[0079] Figure 5 compares the velocity field streamlines of the fluid in the microchannel with and without an alternating electric field. As can be seen from Figure 5(a), when there is no alternating electric field, the fluid flow in the microchannel is stable and orderly, parallel to the channel axis, and belongs to laminar flow. Figure 5(b) shows that when an alternating electric field is introduced, the fluid forms a periodic swirling flow near the electrode on the wall of the microchannel, indicating that electroosmosis of the alternating electric field can effectively induce chaotic flow.

[0080] In this embodiment, referring to Figure 6, Figure 6 shows the change of solution mixing efficiency at the microchannel outlet with time under different alternating electric field strengths.

[0081] In Figure 6(a), E0 = 5V, w = 50Hz;

[0082] In Figure 6(b), E0 = 10V, w = 50Hz;

[0083] In Figure 6(c), E0 = 15V, w = 50Hz;

[0084] In Figure 6(d), E0 = 20V and w = 50Hz.

[0085] It can be observed that when the alternating electric field strength is 5 V / cm, the concentration of the mixed solution inside the ring exhibits a polarization between the upper and lower inner walls, with the concentration closer to 1 mol / m³ closer to the upper wall of the ring. 3 At this point, the alternating electric field frequency has little effect on the solution mixing efficiency. As the electric field strength gradually increases from 5 V / cm to 20 V / cm, the concentration of the mixed solution inside the annulus gradually becomes uniform, and the concentration differentiation between the upper and lower inner electrodes significantly weakens. Overall, the solution mixing efficiency at the microchannel outlet increases with the alternating electric field frequency. Therefore, when other conditions remain constant, selecting an appropriate alternating electric field strength can improve the fluid mixing efficiency in the microchannel.

[0086] In this embodiment, referring to Figure 7, Figure 7 shows the change of solution mixing efficiency at the microchannel outlet over time under different alternating electric field strengths.

[0087] In Figure 7(a), E0 = 20V, w = 20Hz;

[0088] In Figure 7(b), E0 = 20V, w = 30Hz;

[0089] In Figure 7(c), E0 = 20V, w = 40Hz;

[0090] In Figure 7(d), E0 = 20V and w = 50Hz.

[0091] It can be observed that when the alternating electric field frequency is 20Hz, the concentration of the mixed solution inside the ring exhibits a polarization between the upper and lower inner walls, with the concentration closer to 1 mol / m³ closer to the upper wall of the ring. 3 At this point, the alternating electric field frequency has little effect on the solution mixing efficiency. As the electric field frequency gradually increases from 20Hz to 50Hz, the concentration of the mixture inside the annulus gradually becomes more uniform, and the polarization of concentration between the upper and lower inner walls significantly weakens. Overall, the solution mixing efficiency at the microchannel outlet increases with the alternating electric field frequency. Therefore, when other conditions remain constant, selecting an appropriate alternating electric field frequency can improve the fluid mixing efficiency in the microchannel.

[0092] During operation, the enhanced electric field generates a stronger electroosmotic effect and a more intense chaotic flow field, further improving mixing efficiency. This increased mixing efficiency leads to a rise in fluid viscosity. The vibratory viscometer 3 feeds back the new viscosity value to the control unit 4, which then compares and adjusts it again. This process repeats continuously, forming a dynamic, automatic closed-loop control until the fluid viscosity stabilizes near the set target value. At this point, the error signal e(t) approaches zero, and the system reaches a stable state. This indicates that the fluid adsorbent material has achieved a highly uniform mixing state, the mixing process is complete, ensuring a highly uniform final mixture and solving the problem of low efficiency in traditional mixers due to a lack of real-time feedback.

[0093] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
