Description

Technical Field

[0001] This utility model relates to the field of physical and chemical reaction equipment technology, and in particular to an ultrasonic, microwave, ultraviolet light combined vacuum reaction device. Background Technology

[0002] Ultrasound, microwaves, ultraviolet light, and vacuum-assisted technologies, as typical physical field enhancement methods, each have their advantages in chemical and physical reactions, exhibiting unique mechanisms of action and engineering application value. For example, ultrasound utilizes cavitation, mechanical, and thermal effects to induce physicochemical changes and promote reactions; in the field of electromagnetics, microwaves generate heat through the interaction of high-frequency electromagnetic waves with molecules, exhibiting selective and efficient heating characteristics and influencing reaction kinetics; in optics, ultraviolet light, with its high energy, induces photochemical reactions and can also synergize with ultrasound and microwaves. Vacuum technology creates a vacuum environment to lower boiling points, prevent thermal decomposition, and reduce side reactions. Although ultrasound, microwaves, ultraviolet light, and vacuum each have advantages in catalytic reactions, current reaction devices mostly employ a single technology for catalytic reactions. Single catalytic methods often fail to achieve the expected catalytic effect and are relatively limited in scope. For instance, ultrasound technology has limited atomization effects and difficulty in controlling cavitation; microwave technology suffers from uneven heating and limited effectiveness on non-polar substances; ultraviolet light technology has weak penetration and complex catalyst selection; and vacuum technology has high equipment costs and complex operation. Therefore, by constructing an integrated reaction system of ultrasound-microwave-ultraviolet-vacuum through the principle of multi-physics field synergistic coupling, the inherent limitations of a single physical field can be overcome.

[0024] Please refer to Figure 1 and 2 The present invention provides an ultrasonic, microwave, ultraviolet light combined vacuum reaction device, which mainly includes a housing 1, an ultrasonic vibration platform 2, an ultraviolet lamp 3, a microwave transmitter 4, and a vacuum pump 5.

[0025] The interior of the chamber 1 is a reaction space. The shape of the chamber 1 can be flexibly set according to the actual application scenario. For example, in this embodiment, the shape of the chamber 1 is a cuboid. The front side of the chamber 1 is generally provided with an openable door 7 to allow the reaction materials to be placed in or removed. To facilitate the movement of the chamber 1, the bottom of the chamber 1 is also provided with multiple casters 13, which are omnidirectional casters.

[0026] Please refer to Figure 3 , 4 5. The ultrasonic vibration platform 2 is disposed within the housing 1. The ultrasonic vibration platform 2 includes a loading platform 14 and multiple ultrasonic transducers 15. Each ultrasonic transducer 15 is circumferentially spaced around the loading platform 14. Each ultrasonic transducer 15 includes a piezoelectric ceramic 20 and an ultrasonic amplitude transformer 21. The piezoelectric ceramic 20 is fixed within the housing 1 and connected to the ultrasonic amplitude transformer 21, which is connected to the loading platform 14. Each ultrasonic transducer 15 outputs ultrasonic vibration through the piezoelectric ceramic 20, and then the ultrasonic amplitude transformer 21 amplifies the amplitude of the output ultrasonic vibration and converts the vibration direction to the desired direction, causing the loading platform 14 to vibrate vertically.

[0027] Specifically, the housing 1 is equipped with a partition 11, which is horizontally arranged and divides the housing 1 into upper and lower spaces. The loading platform 14 is located above the partition 11. The ultrasonic transducer 15 also includes a vibrating head 23. The ultrasonic amplitude transformer 21 is horizontally arranged, and one end of the ultrasonic amplitude transformer 21 near the loading platform 14 has a truncated cone with a gradually decreasing diameter. One end of the vibrating head 23 is connected to the truncated cone, and the other end is connected to the loading platform 14.

[0028] In some embodiments, the ultrasonic amplitude transformer 21 has a flange 22 at one end away from the loading platform 14. A fixed mounting bracket 18 is provided inside the housing 1, with its lower end fixedly mounted on the partition 11. The ultrasonic amplitude transformer 21 passes horizontally through the mounting bracket 18, and the flange 22 is fixedly connected to the mounting bracket 18. The piezoelectric ceramic 20 is fixedly connected to the side of the flange 22 away from the loading platform 14. Thus, when the piezoelectric ceramic 20 is energized, it inputs horizontal vibrations to the ultrasonic amplitude transformer 21. The ultrasonic amplitude transformer 21 converts the horizontal vibrations into vertical vibrations, which are then applied to the loading platform 14 via the vibrating head 23, causing the loading platform 14 to vibrate vertically. Here, an ultrasonic microwave driving power supply 12 is provided below the partition 11 inside the housing 1. The ultrasonic microwave driving power supply 12 is connected to the piezoelectric ceramic 20 to supply power to it.

[0029] It should be noted that, in order to ensure that the platform 14 can generate a good vibration effect on the reactants placed on it, the number of ultrasonic transducers 15 can be flexibly set according to the shape and specifications of the platform 14. For example, in this embodiment, the platform 14 is rectangular, and there are four ultrasonic transducers 15, arranged in pairs on both sides of the platform 14. Figure 7 As shown in this embodiment, under the action of the ultrasonic transducer 15, the loading platform 14 can generate obvious vertical vibration, thereby producing a good vibration effect on the reactant.

[0030] The ultraviolet lamp 3 is located on the top of the housing 1 and above the loading platform 14. Specifically, the ultraviolet lamp 3 is installed on the top of the housing 1, aimed at the center of the loading platform 14, and can irradiate the reactants placed on the loading platform 14 with ultraviolet light.

[0031] Combination Figure 6 As shown, the microwave transmitter 4 is disposed inside the housing 1 and located on one side of the loading platform 14. The microwave transmitter 4 can emit microwaves onto the reactive material placed on the loading platform 14. Specifically, the upper surface of the loading platform 14 is provided with a receiving groove 19, which is used to place the reactive material. Side baffles 17 extending upwards are provided on both sides of the receiving groove 19, and the microwave transmitter 4 is fixed to the side baffles 17. The microwave transmitter 4 is a prior art technology, mainly comprising a transmitter body 25, a magnetron 27, and a microwave emission cavity 26. The microwave emission cavity 26 is disposed on the upper part of the transmitter body 25, and the magnetron 27 is disposed inside the microwave emission cavity 26. The ultrasonic microwave driving power supply 12 is connected to the microwave transmitter 4 to supply power to the microwave transmitter 4. The transmitter body 25 irradiates the reactive material placed on the loading platform 14 with ultraviolet light through the magnetron 27.

[0032] The number of microwave transmitters 4 can be flexibly set to multiple depending on the application scenario. Each microwave transmitter 4 is disposed on the outside of the loading platform 14 and can emit microwaves upwards towards the loading platform 14. In this embodiment, the number of microwave transmitters 4 is set to two, and the two microwave transmitters 4 are symmetrically installed on the two side baffles 17, respectively disposed on both sides of the receiving groove 19, and can emit microwaves to the reaction material placed in the receiving groove 19 on the loading platform 14. It is understood that in other embodiments, the number of microwave transmitters 4 is not limited to the specific number described in this embodiment, and its number can be increased or decreased according to the needs of the material reaction.

[0033] In some embodiments, considering the cooling issue during operation of the microwave transmitter 4, the microwave transmitter 4 further includes a water-cooling assembly 28. The water-cooling assembly 28 is disposed on one side of the transmitter body 25. A fan 24 is provided at the end of the ultrasonic amplitude transformer 21 away from the loading platform 14, and the fan 24 is located below the water-cooling assembly 28. Furthermore, to prevent the piezoelectric ceramic 20 from being exposed to microwaves and causing interference during operation of the microwave transmitter 4, an L-shaped isolation cover 16 is provided above the piezoelectric ceramic 20. One side of the isolation cover 16 is fixed to the upper part of the mounting bracket 18, and the other side extends to one side of the loading platform 14 without contacting the loading platform 14, thus covering the piezoelectric ceramic 20. A side baffle 17 is vertically fixed to the isolation cover 16, so that the microwave transmitter 4 is mounted on the outside of the side baffle 17.

[0034] The vacuum pump 5 is connected to the housing 1 to evacuate the interior of the housing 1. Specifically, the vacuum pump 5 is located inside the housing 1 below the partition 11. The vacuum pump 5 is connected to a pneumatic triplet 6, which in turn connects to the space above the partition 11 in the housing 1. The vacuum pump 5 evacuates the space above the partition 11 in the housing 1, creating a vacuum environment for the reactants placed in the receiving slot 19 on the loading platform 14. The pneumatic triplet 6 is a conventional pneumatic component, integrating an air filter, a pressure reducing valve, and an oil mist lubricator. The pneumatic triplet 6 filters moisture and oil from the air, improving the service life of the vacuum pump 5.

[0035] In some embodiments, a temperature and humidity sensor 8 and a camera 9 are provided on the top of the housing 1. The temperature and humidity sensor 8 is installed on the top of the housing 1 and has a downward-extending temperature and humidity sensing probe 10 to monitor the temperature inside the housing 1. The camera 9 is a rotating spherical camera, installed on the top of the housing 1, above the loading platform 14, and can capture images of the reaction process of the reactants placed in the receiving slot 19 on the loading platform 14.

[0036] The working principle of the ultrasonic-microwave-ultraviolet-light combined vacuum reaction device provided by this utility model is as follows: The reactant is placed in the receiving slot 19 of the carrying platform 14, and the housing 1 is closed. The ultrasonic vibration platform 2, the microwave transmitter 4, the ultraviolet lamp 3, and the vacuum pump 5 can be activated simultaneously to act on the reactant. Alternatively, the reactant can be acted on separately in different sequences. That is, for the four selections, when k is 1, 2, 3, and 4, the permutation numbers are respectively: When k=1, P(4,1)=4; When k=2, P(4,2)=12; When k=3, P(4,3)=24; When k=4, P(4,4)=24; This allows for 64 different combinations of functions (4+12+24+24), and the duration of each function can be controlled. The reaction process can also be monitored using the temperature and humidity sensor 8 and the camera 9, recording the changes in the state and parameters of the substances during the reaction.

It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.

[0038] Where there is no conflict, the embodiments and features described above can be combined with each other.
