Description

technical field [0001] The invention relates to a tunnel-type multi-mode microwave resonant cavity with a rotary function. Background technique [0002] Microwaves are electromagnetic waves with a frequency of 300MHz-300GHz, and the wavelength range is between 0.1cm-100cm. According to international regulations, the frequencies for civilian use are 915MHz and 2450MHz. The power of domestic microwave ovens in my country is 2450MHz. Microwave acts on polar molecular substances, and the internal molecules or atoms of the heated material vibrate at high frequency in the microwave field to generate "internal friction heat" so that the microwave energy is transferred to the molecules or atoms in the form of heat, thereby increasing the temperature of the entire material Without any heat conduction process, the inside and outside of the material can be heated and heated at the same time. The heating speed is fast, and only a fraction or a few tenths of the energy consumption of tra...

[0003] The purpose of the present invention is to overcome the disadvantage of poor radiation uniformity of the traditional cubic box-type microwave resonator, and propose a tunnel-type multi-mode microwave resonator with rotary function, which has more reflections than the traditional cuboid box-type microwave resonator On the other hand, the positions of four microwave energy feed ports were simulated and positioned by using the high-frequency structure simulation software HFSS, and four microwave tubes totaling 4KW were respectively fed into microwave energy from different directions. After electromagnetic wave energy feed simulation, the energy distribution of the microwave resonator was improved. The focus points (hot spots) of microwave energy in the resonant cavity are significantly reduced. At the same time, the middle part of the resonant cavity is designed with a pipeline installation position, which can be assembled with pipelines made of low microwave absorption materials such as ceramics and glass. The installed pipeline can be driven by the rotary device. Rotate down to make the material in the tube more evenly irradiated by microwave
