Multi-mode mixing cavity adjusting method and control system thereof

Abstract

The invention provides a multi-mode mixing cavity adjusting method and a control system thereof, and relates to the technical field of microwave multi-mode, and the multi-mode mixing cavity adjusting method comprises the steps: obtaining a target reflection microwave outputted by a circulator; determining a target adjustment strategy matched with the target reflection microwave; and based on the target processing strategy, controlling and adjusting the position of a metal sliding block on a double-matching branch so as to reduce microwave reflection entering the multi-mode mixing cavity through the circulator. The impedance of the multi-mode mixing cavity and the impedance of the double-matching branch are adjusted by adjusting the position of the metal sliding block on the double-matching branch, and the target position of the metal sliding block is determined when the impedance of the multi-mode mixing cavity and the impedance of the double-matching branch are adjusted to be optimal; therefore, when the microwave source is subsequently installed at the target position and the waveguide and the cavity are sequentially connected, the purpose that microwaves are fed into the cavity as much as possible and the magnetron is not damaged is achieved, the energy consumption is reduced, and the service life of the multi-mode mixing cavity adjusting equipment is prolonged.

Description

Technical field [0001] The present invention relates to the field of microwave multimode technologies, and is, but is not limited to, a multimode mix cavity adjustment method and a control system thereof. Background technique [0002] Nowadays, as people's research on microwave technology, the application of microwave technologies is increasingly widely used, and common use of microwave equipment for disinfecting and exhaust gas treatment. [0003] The existing microwave device is mostly a multimode mixing chamber such that multiple reflection occurs when the microwave enters the cavity, resulting in small amounts of microwaves, but not only damage to magnetron, but also using microwave disinfection and exhaust gas. The effect of processing is not complete. [0004] Therefore, how to take microwaves as much as possible into the cavity and do not harm the magnetron and become a key issue that needs to be solved now. Inventive content [0005] It is an object of the present invent...
