[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8An embodiment of the present invention is as follows: a multi-frequency ultrasonic vacuum emulsification reactor, comprising a bottom plate 13, a support plate 6 and a support cabinet 7 are installed on the top of the bottom plate 13, the support cabinet 7 is located on one side of the support plate 6, partitions 9 are evenly arranged inside the support cabinet 7, an ultrasonic generator 11 is installed between the partition 9 and the support cabinet 7, connecting rods 5 are installed on one side outer walls of the support cabinet 7 and the support plate 6, a reactor outer cylinder 1 is installed between two groups of the connecting rods 5, a vacuum pump 15 is installed on the top of the bottom plate 13, a vacuum pipe 16 is installed on the output end of the vacuum pump 15, the vacuum pipe 16 is located behind the reactor outer cylinder 1, a vacuum valve 17 is installed on the outer surface of the vacuum pipe 16, a reactor inner cylinder 3 is installed inside the reactor outer cylinder 1, ultrasonic transducers 4 are evenly arranged on the bottom wall of the reactor outer cylinder 1, and the ultrasonic transducer 4 is electrically connected to the ultrasonic generator 11.

[0025] Furthermore, the outer cylinder 1 of the reactor is fixed between the support plate 6 and the support cabinet 7 by a connecting rod 5, and a plurality of ultrasonic generators 11 are installed in the support cabinet 7. A plurality of ultrasonic transducers 4 are arranged between the outer cylinder 1 of the reactor and the inner cylinder 3 of the reactor. Each ultrasonic generator 11 is connected to a plurality of ultrasonic transducers 4, so that the ultrasonic generator 11 provides matching frequency signals for the plurality of ultrasonic transducers 4, and controls the plurality of ultrasonic transducers 4 to work under the same frequency condition at the same time. The ultrasonic generator 11 provides high-frequency electric energy for the ultrasonic transducer 4, and the ultrasonic transducer 4 converts the electric energy into mechanical energy to generate ultrasonic vibration. The plurality of ultrasonic generators 11 provide frequency signals of different frequencies for the ultrasonic transducer 4, and generate alternating ultrasonic vibrations on the inner cylinder 3 of the reactor. The changing high-frequency vibrations propagate in the liquid material in the inner tube 3 of the vibration reactor, forming alternating waves of sparse and dense, producing cavitation effects, mechanical effects and thermal effects. The cavitation effect causes the tiny bubbles in the liquid to form, grow and collapse rapidly under the action of ultrasound, generating local high temperature, high pressure and strong shock waves, thereby breaking the material particles and refining the emulsion droplets. The mechanical effect uses the vibration of the ultrasonic wave to generate strong friction, collision and shear force between the material particles, further promoting the dispersion and emulsification of the material. The thermal effect helps to increase the reaction rate and the fluidity of the material. At the same time, the air in the inner tube 3 of the reactor is extracted through the vacuum pump 15, so that the inside of the inner tube 3 of the reactor is in a vacuum state. Under the vacuum condition, the material The gas and volatile components in the material are effectively removed, reducing the presence of bubbles, allowing ultrasonic energy to be more effectively transferred to the material, enhancing the ultrasonic cavitation and emulsification effects. At the same time, the vacuum environment can reduce the boiling point of the material, prevent the deterioration or volatilization of certain components at high temperatures, and help maintain the quality and performance of the product. The vacuum can also prevent the material from contacting with oxygen in the air and reduce the occurrence of oxidation reactions. Emulsification is carried out by combining multi-frequency ultrasonic cavitation and vacuum environment, so that the emulsification reaction can be carried out at a lower temperature and pressure, reducing the impact on heat-sensitive materials and volatile components. It can be applied to materials of various properties, which to a certain extent expands the scope of application of the device, and in a closed vacuum environment. The reaction can reduce the contact between the material and the outside air, reduce the risk of oxidation and pollution, and help reduce the waste of materials. The synergistic effect of the two can make the particle size of the emulsion droplets smaller and the distribution more uniform, achieve a finer emulsification and dispersion effect, greatly improve the stability and quality of the product, and to a certain extent improve the production efficiency. The power of each ultrasonic generator 11 is adjusted separately to accurately control the ultrasonic power emitted by the ultrasonic transducer 4. Different powers are set for the ultrasonic transducers 4 at different positions according to the material distribution and emulsification requirements to make the emulsification effect more uniform. The vacuum gauge 18 monitors the vacuum degree in the inner tube 3 of the reactor, which is convenient for the controller 12 to accurately control the vacuum pump 15 to extract air.

[0027] Furthermore, the temperature inside the inner tube 3 of the reactor is monitored by a temperature sensor 1 22 installed on the top of the reactor, a temperature sensor 3 24 installed on the bottom of the reactor, and a temperature sensor 2 23 installed on the upper, middle and lower parts of the reactor wall, and the temperature sensor 1 22, the temperature sensor 2 23 and the temperature sensor 3 24 are electrically connected to the controller 12. When the temperature at a certain position deviates from the set value, the controller 12 can adjust the heating and cooling process in time according to the temperature distribution. The temperature distribution inside the inner tube 3 of the reactor is comprehensively monitored by multi-point temperature monitoring. If the temperature at the bottom of the reactor is too high, the alarm 10 sounds an alarm, and the controller 12 can increase the flow rate of the cooling medium at the top of the reactor, or reduce the flow rate of the heating medium at the bottom of the reactor to restore the temperature to a uniform state, so as to maintain the uniformity of the temperature of the entire reactor body and avoid local overheating, thereby improving the overall quality and stability of the emulsification reaction to a certain extent.

[0028] See also Figure 2 , Figure 5 and Figure 6 An embodiment of the present invention is: a multi-frequency ultrasonic vacuum emulsification reactor, wherein the outer surface of the inner cylinder 3 of the reactor is equipped with three sets of jackets 25, the jacket 25 is located inside the outer cylinder 1 of the reactor, a pipe 26 and a pipe 27 are installed inside the jacket 25, and a thermal insulation board 28 is installed inside the jacket 25, and the thermal insulation board 28 is located between the pipe 1 26 and the pipe 2 27.

[0029] Furthermore, jackets 25 are arranged at the upper, middle and lower parts of the outer wall of the inner tube 3 of the reactor, and pipes 1 26 and 27 are arranged in the jackets 25. The inner tube 1 26 is used for hot water, and the inner tube 27 is used for cooling water. The pipes 1 26 and 27 are insulated by a heat insulation board 1 28 to prevent mutual interference between the pipes 1 26 and 27. The hot water flows in the pipe 1 26 to heat the material in the inner tube 3 of the reactor, and the heat is evenly transferred to the material to ensure that the heat can be taken away in time. The cooling water in the pipe 2 27 is The circulation in the reactor body helps to take away the heat of the material in time and reduce the occurrence of local overheating. By arranging a segmented jacket 25 outside the inner tube 3 of the reactor, the jacket 25 is divided into three sections: upper, middle and lower sections along the height direction of the inner tube 3 of the reactor. The temperature of each area can be controlled independently. By adjusting the flow rate of the heating or cooling medium in each section of the jacket 25, the temperature of the material at different heights of the reactor body can be made more uniform, and the local overheating caused by the shearing action of the stirring and emulsifying heads, which leads to changes in the properties of the material, is reduced, thereby improving the overall quality and stability of the product to a certain extent.

[0030] See also Figure 2 and Figure 7 , an embodiment provided by the present invention: a multi-frequency ultrasonic vacuum emulsification reactor, the top of the cylinder cover 2 is equipped with a control motor 29, the output end of the control motor 29 is equipped with a stirring main rod 30, the stirring main rod 30 is located inside the outer cylinder 1 of the reactor, the outer surface of the stirring main rod 30 is equipped with a turbine stirring paddle 31, an anchor stirring paddle 32 and a toothed emulsification head 33, the anchor stirring paddle 32 is located between the toothed emulsification head 33 and the turbine stirring paddle 31, the stirring main rod 30 and the turbine stirring paddle 31, the anchor stirring paddle 32 and the toothed emulsification head 33 are connected.

[0031] Furthermore, during the emulsification reaction, the control motor 29 needs to be operated to drive the stirring main rod 30, the turbine stirring paddle 31, the anchor stirring paddle 32 and the toothed emulsifying head 33 to rotate. The turbine stirring paddle 31 can generate a strong radial flow to allow the materials to be quickly mixed in the horizontal direction. The anchor stirring paddle 32 is mainly used to scrape the kettle wall to promote the exchange of materials near the kettle wall and the materials in the central area, thereby improving the temperature uniformity. The toothed emulsifying head 33 generates a strong shear force through high-speed rotation to break large droplets into tiny droplets. At the same time, the emulsifier molecules are adsorbed at the oil-water interface to reduce the interfacial tension, so that the tiny droplets can be stably dispersed in another liquid to form an emulsion. The toothed emulsifying head 33 is tooth-shaped, which can provide a softer dispersion effect while generating shear force, which can reduce the damage to sensitive components during the emulsification process, improve the stability of the emulsion to a certain extent, and enable the reactor to handle materials of different properties. The stirring paddle 31, the anchor stirring paddle 32 and the toothed emulsifying head 33 are all fixed on the stirring main rod 30 by a locking assembly, which is convenient for disassembly. When disassembly is required, the barrel cover 2 and the stirring main rod 30 are removed, and then the micro electric push rod 34 is controlled to shorten by the controller 12, driving the limit block 37 to be retracted into the placement groove 35, releasing the locking effect on the fixing ring 36, so that the turbine stirring paddle 31, the anchor stirring paddle 32 and the anchor stirring paddle 32 can be removed from the stirring main rod 30. A detachable double-layer stirring paddle is adopted, with the upper layer being the turbine stirring paddle 31 and the lower layer being the anchor stirring paddle 32, which helps to make the emulsification reaction more complete during stirring. After the reaction is completed, the turbine stirring paddle 31, the anchor stirring paddle 32 and the toothed emulsifying head 33 are removed, which simplifies the internal structure of the reactor to a certain extent, facilitates cleaning and disinfection, reduces dead corners, prevents material residues from causing bacteria to grow, and thus affects the emulsification quality of the material next time, and improves the cleaning efficiency.
