Description

Technical Field

[0001] This utility model belongs to the field of microwave reaction device technology, specifically, it relates to an improvement of an industrial microwave continuous high-temperature device. Background Technology

[0002] With the continuous development of microwaves, many microwave reaction devices have emerged that use microwaves to heat samples that require high-temperature heating. These devices consist of a microwave source and a microwave resonant cavity. The sample to be reacted is placed inside the microwave resonant cavity, and microwaves heat the sample, causing it to react. After the reaction is complete, the sample can be removed from the microwave resonant cavity. However, this type of microwave reaction device can only place and remove samples one by one when heating them. In industrial production, where a large number of samples need to be heated, the heating efficiency is too low if samples are placed and removed sequentially, which cannot meet the needs of production.

[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0004] This invention addresses the aforementioned technical problems of existing microwave reaction devices by proposing an industrial-grade continuous high-temperature microwave device that enables continuous high-temperature heating of large batches of samples, thus meeting the needs of industrial processing and production.

[0005] To achieve the above-mentioned utility model / design objectives, the present utility model adopts the following technical solution:

[0006] An industrial-grade microwave continuous high-temperature device includes:

[0007] A support base frame is provided with a placement position for placing a sample plate containing a sample;

[0008] The shell has a microwave resonant cavity formed inside it;

[0009] A microwave source device used to feed microwaves into a microwave resonant cavity;

[0010] A reaction channel, which is transparent to waves, is located inside the microwave resonant cavity and includes an outer channel;

[0011] And a detachable inner channel located within the outer channel;

[0012] The telescopic power component is telescopically mounted on the support base. It moves the sample plate placed at the placement position by telescopically pushing it to move multiple sample plates located on one side of the placement position and sequentially pass through the inner channel.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are:

[0014] This utility model discloses an industrial continuous high-temperature microwave device, which includes a microwave resonant cavity and a reaction channel arranged within the microwave resonant cavity. A microwave source device is also provided to feed microwaves into the microwave resonant cavity. When a large number of industrial samples require continuous high-temperature reactions, the sample plates placed at the designated positions can be moved by the telescopic movement of a telescopic power component mounted on the support frame. This moves multiple sample plates arranged side-by-side on one side of the placement position, causing them to pass sequentially through the inner channel. The energy generated by the microwaves heats the sample plates passing through the inner channel, inducing a reaction. This achieves continuous high-temperature heating of multiple samples, meeting the production needs of continuous high-temperature reactions of multiple samples in industrial applications.

[0026] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] In some embodiments of this application, an industrial microwave continuous high-temperature device is proposed, which can be used to achieve continuous high-temperature heating of large batches of samples, thereby accelerating the efficiency of industrial production.

[0028] Industrialized microwave continuous high-temperature devices include:

[0029] A support base 100 is provided, and a placement position 110 is provided on the support base 100. The support base 100 is used to support the entire high-temperature device.

[0030] The placement position 110 is used to place the sample plate 610 for the reaction. A sample container 620 is provided on the sample plate 610, and the reaction sample is placed inside the sample container 620. The sample to participate in the high-temperature reaction is placed at the placement position 110 using the sample plate 610 as a carrier.

[0031] The housing 200 is mounted on the support base 100 and connected to the support base 100, and a microwave resonant cavity 210 is formed inside it;

[0032] A microwave source device for generating microwaves and feeding microwaves into a microwave resonant cavity 210;

[0033] The reaction channel 400 is transparent to waves and is located inside the microwave resonant cavity 210. It includes an outer channel 410.

[0034] And an inner channel 420 that can be detachably set within the outer channel 410.

[0035] In some embodiments of this application, the inner channel 420 is inserted inside the outer channel 410.

[0036] During disassembly, the inner channel 420 can be pulled out relative to the outer channel 410, making disassembly simple and convenient.

[0037] The inner channel 420 forms a sample reaction space, and the sample container 620 of the sample plate 610 and the sample built into the sample container 620 will react inside the inner channel 420 when passing through it.

[0038] To protect the inner channel 420 and prevent the reactants from corroding it, a coating is applied to the inner wall of the inner channel 420. The coating serves to prevent corrosion and to prevent the volatiles generated by the reaction between the inner channel 420 and the sample, thus ensuring the accuracy of the reaction sample.

[0039] The microwave source generating device feeds microwaves into the microwave resonant cavity 210. Since the reaction channel 400 is located inside the microwave resonant cavity 210 and is transparent, microwaves can pass through the reaction channel 400 to heat the sample in the inner channel 420 and cause it to react.

[0040] The reaction channel 400 used for heating the sample is configured with an outer channel 410 and an inner channel 420 that can be detached inside the outer channel 410. If the reaction channel 400 needs to be replaced, the inner channel 420 can be directly disassembled without disassembling the outer channel 410, which is convenient for disassembly and replacement.

[0041] When the sample passes through the inner channel 420, the microwaves fed into the microwave resonant cavity 210 by the microwave source generator will heat the sample through the wave-transparent reaction channel 400. The sample will react after being heated and will volatilize gas. Some sample reactions may volatilize corrosion-resistant gases. Under the long-term high-temperature heating reaction, the coating on the inner channel 420 may be corroded and damaged. By setting the inner channel 420 of the reaction channel 400 to be detachable, the inner channel 420 can be replaced when the coating of the inner channel 420 is damaged.

[0042] Alternatively, if different coatings are required for the inner channel 420 for different reaction samples, the inner channel 420 can be replaced simply by removing it.

[0043] The telescopic power component 500 is telescopically mounted on the support base 100. It moves the sample plate 610 placed at the placement position 110 by telescopically pushing it to move, thereby moving multiple sample plates 610 located on one side of the placement position 110 and passing through the inner channel 420 in sequence.

[0044] The telescopic power component 500 is a hydraulic push rod that is telescopic and connected to a hydraulic station.

[0045] The telescopic power component 500 can be a telescopic cylinder or an electric push rod.

[0046] During heating, multiple sample plates 610 carrying samples are placed sequentially at placement positions 110.

[0047] Specifically, in the initial state, the telescopic power member 500 is in the retracted state, the first sample plate 610 is placed at the placement position 110, the telescopic power member 500 extends a set length, and pushes the sample plate 610 at the placement position 110 to move, so that the sample plate 610 moves from the placement position 110 to the first position.

[0048] After the telescopic power component 500 extends to its position, it retracts and resets. At this time, the second sample plate 610 is placed at the placement position 110. Then, the telescopic power component 500 continues to extend by a set length, pushing the second sample plate 610 from the placement position 110 to the first position. At this time, the first sample plate 610 will be passively moved forward by the pushing force of the second sample plate 610. After the second sample plate 610 is loaded, the third sample plate 610 is placed at the placement position 110 and is pushed to the first position. At this time, the second sample plate 610 is squeezed, which drives the first sample plate 610 to move closer to the microwave resonant cavity 210. This cycle continues, and finally, multiple sample plates 610 are pushed sequentially through the reaction channel 400 and heated and reacted in the reaction channel 400.

[0049] This utility model discloses an industrial continuous high-temperature microwave device, which includes a microwave resonant cavity 210 and a reaction channel 400 arranged within the microwave resonant cavity 210. A microwave source device is also provided to feed microwaves into the microwave resonant cavity 210. When a large number of industrial samples require continuous high-temperature reactions, the telescopic power component 500 on the support frame 100 continuously extends and retracts to move multiple sample plates 610 placed sequentially at placement positions 110. The movement of the sample plates 610 at placement positions 110 pushes multiple sample plates 610 located on one side of placement positions 110 through the inner channel 420. The energy generated by the microwaves heats the multiple sample plates 610 passing through the inner channel 420, causing them to react. This achieves continuous high-temperature heating of multiple samples, meeting the production needs of continuous high-temperature reactions of multiple samples in industrial applications.

[0050] In some embodiments of this application, multiple inner channels 420 are provided, and the multiple inner channels 420 are arranged sequentially along the length direction of the outer channel 410, with adjacent inner channels 420 fitting together.

[0051] The inner layer channel 420 is configured as a structure of multiple interlocking inner layer sub-channels 421, which makes it easy to disassemble and replace parts of the inner layer channel 420.

[0052] By configuring the inner channel 420 as a structure of multiple inner sub-channels 421 spliced ​​together, during assembly, the multiple inner sub-channels 421 can be inserted into the outer channel 410 in sequence to complete the assembly. Compared with the long inner channel 420 structure with a single integrated structure, this method is not only easier to process but also easier to assemble.

[0053] In some embodiments of this application, the inner sub-channel 421 includes:

[0054] The inner channel body 4211 and the inner channel cover 4212 detachably connected to the inner channel body 4211.

[0055] The inner channel cover 4212 is fastened to the inner channel body 4211 to form the inner channel 420. The inner channel body 4211 and the inner channel cover 4212 are designed to be detachable. When the coating of a part of the inner channel 420 is severely damaged, such as when the inner channel cover 4212 is severely damaged, only part of the inner channel cover 4212 needs to be replaced, without replacing the entire inner channel 420, thus reducing production costs.

[0056] In some embodiments of this application, the outer channel 410 includes a plurality of outer sub-channels 411, and the plurality of outer channels 410 are arranged sequentially in the microwave resonant cavity 210 along the sample plate 610 conveying direction, with the end faces of adjacent outer channels 410 being fitted and mated together.

[0057] The outer channel 410 is configured as a structure of multiple outer sub-channels 411, which facilitates processing and molding.

[0058] In some embodiments of this application, a thermal insulation material 520 is provided inside the microwave resonant cavity 210, and the thermal insulation material 520 fills the position between the microwave resonant cavity 210 and the outer channel 410.

[0059] The insulation material 520 is used to achieve thermal insulation of the reaction channel 400 to avoid heat loss and affect the reaction effect. Its material can be alumina polycrystalline fiber.

[0060] In some embodiments of this application, the microwave source device includes a plurality of magnetrons 300, which are uniformly arranged around the circumference of the microwave resonant cavity 210. The magnetrons 300 are used to generate microwaves. Arranging the plurality of magnetrons 300 uniformly around the circumference of the microwave resonant cavity 210 allows for uniform microwave radiation around the perimeter of the microwave resonator, ensuring uniform heating of the sample within the reaction channel 400.

[0061] In some embodiments of this application, the industrial microwave continuous high-temperature device includes a support frame 120, which is disposed inside and fixedly connected to the microwave resonant cavity 210, and the outer channel 410 is disposed on the support frame 120.

[0062] The support frame 120 is used to support and fix the outer channel 410. It includes a support frame body and support feet arranged on the support frame body. Multiple support feet are provided and fixed to the bottom wall of the microwave resonant cavity 210.

[0063] In some embodiments of this application, the industrial microwave continuous high-temperature device includes a first enclosed shell 710 disposed at one end of a microwave resonant cavity 210 and connected to one end of the microwave resonant cavity 210. A first guide channel 720 is disposed inside the first enclosed shell 710 and is connected to one end of the reaction channel 400. A sample plate inlet 711 is disposed on the first enclosed shell 710.

[0064] The second enclosure 750 is disposed at the other end of the microwave resonant cavity 210 and is connected to the other end of the microwave resonant cavity 210. A second guide channel 760 is disposed inside the second enclosure 750 and is connected to the other end of the reaction channel 400. A sample plate outlet 751 is disposed on the second enclosure 750.

[0065] The first guide channel 720 and the second guide channel 760 within the first closed shell 710 and the second closed shell 750 can be used to connect with the reaction channel 400. The sample plate 610 is pushed into the first reaction channel 400 through the sample plate inlet 711 on the first closed shell 710. As the sample plate 610 is pushed and moved, it moves continuously from the first guide channel 720 into the reaction channel 400, enters the second guide channel 760 after passing through the reaction channel 400, and finally exits from the sample plate outlet 751 at the second closed shell 750.

[0066] The first guide channel 720, the second guide channel 760, and the reaction channel 400 have the same structure, and will not be described in detail here.

[0067] In addition, the first sealing shell 710 and the second sealing shell 750 arranged at both ends of the microwave resonant cavity 210 can also play a certain role in preventing microwave leakage.

[0068] In some embodiments of this application, along the conveying direction of the sample plate 610, a first wave-absorbing component 730 and a first wave-suppressing component 740 are sequentially arranged on the inner wall of the first enclosed shell 710, arranged circumferentially along the first guide channel 720.

[0069] On the inner wall of the second enclosed shell 750, a second wave-suppressing component 780 and a second wave-absorbing component 770 are arranged in sequence along the circumference of the second guide channel 760.

[0070] To further prevent microwave overflow and leakage, a first microwave absorbing component 730, a first microwave suppressing component 740, a second microwave absorbing component 770, and a second microwave suppressing component 780 are respectively arranged in the first enclosed shell 710 and the second enclosed shell 750 on both sides of the microwave resonant cavity 210.

[0071] If microwaves leak from the microwave resonant cavity 210 to both sides, they will first be suppressed by the corresponding suppression components and then absorbed by the absorption components. Through the combined action of the suppression and absorption components, microwave leakage is greatly reduced.

[0072] By arranging the first absorbing component 730 and the first suppressing component 740 circumferentially along the first guide channel 720, and the second absorbing component 770 and the second suppressing component 780 circumferentially along the second guide channel 760, the absorbing and suppressing effects can be guaranteed.

[0073] In some embodiments of this application, the first wave-absorbing component 730 is a wave-absorbing plate made of wave-absorbing material, and the first wave-suppressing component 740 is a first wave-suppressing plate, which includes a wave-suppressing plate body and a plurality of protruding teeth connected to the wave-suppressing plate body, with a spacing between adjacent protruding teeth.

[0074] In some embodiments of this application, an infrared detection sensor 800 is assembled onto the housing 200 for detecting the temperature inside the inner channel 420. A detection channel is provided inside the insulation material of the housing 200, and a detection port 430 is provided through the reaction channel 400, which is connected to the detection channel.

[0075] The infrared sensor 800 can be used to detect the reaction temperature at the inner channel 420.

[0076] In some embodiments of this application, a cover 900 is also included, which is fixed to the support base 100 and extends from the first enclosure 710 to the second enclosure 750.

[0077] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
