Microwave energy feeding device based on large rotating device

Abstract

The invention discloses a microwave energy feeding device based on a large rotating device, which comprises a rotating device (1), an arc-shaped waveguide (2) installed on the outer periphery of the rotating device (1), installed on the arc-shaped waveguide (2), The suppressor (3) at the lower position; the rotating device (1) is circular, the section of the rotating device (1) is concentric with the section of the arc-shaped waveguide (2), and a microwave feeding slot is opened on the circumference of the rotating device (1) (4), the arc-shaped waveguide (2) is provided with a slot corresponding to the size of the microwave feeding slot (4). The invention has reasonable structural design, good safety, no microwave leakage, can realize the scientific combination of the waveguide and the rotating device, the microwave distribution is uniform, and can greatly improve the heating efficiency of the microwave, especially for the large rotating device, the microwave heating efficiency is higher, which can solve the problem of The conventional fixed waveguide and the rotating device cannot realize the technical problem of energy feeding connection, and at the same time, it can also solve the problem that the microwave in the large rotating device cannot uniformly act on the material.

Description

Technical field [0001] The invention relates to the technical field of microwave equipment, in particular to a microwave energy feeding device based on a large rotating device. Background technique [0002] At present, domestic and foreign researches on waveguide rotary joints are mostly used in various mechanical scanning radar systems, and they are limited to the waveguide itself. It is used in square to circular waveguides. The connection between the waveguide and the rotating device can only be on the end face, causing microwave damage Uneven distribution, large-scale rotating devices cannot be heated by microwaves, and fail to meet the industrial requirements of continuous production, and large-scale production of microwave-heated rotating devices cannot be realized. It is currently difficult to realize the energy feeding connection between conventional fixed waveguides and rotating devices. [0003] Therefore, it is necessary to design and develop a reasonable structural desi...

Problems solved by technology

[0002] At present, domestic and foreign research on waveguide rotary joints is mostly used in various types of mechanical scanning radar systems, and is limited to the waveguide itself. It is used on square to circular waveguides. The connection between the waveguide and the rotating device can only be on the end surface, resulting in microwave interference. Uneven distribution, microwave heating of large rotating devices cannot meet the industrial requirements of continuous production, and large-scale production of microwave heating rotating devices cannot be realized. It is currently difficult to realize energy-feeding connection between conventional fixed waveguides and rotating devices
