Embodiment Construction

[0046]Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principles of the present invention.

[0047] Such as figure 1 As shown, the mode stirring device is composed of four parts, which are metal fan blade 1, non-metallic transmission rod 2, wall-passing circular waveguide 3 and motor 4. The non-metal transmission rod 2 passes through the wall-passing circular waveguide 3, and the wall-passing circular waveguide 3 is fixed on the upper wall of the shielding chamber 7 through a flange. The overall structure of the mode stirring device is as follows: figure 1 As shown, the installation distribution in the shielded cabin is as follows figure 2 shown. Illustrate its structure and assembly relationship with a specific embodiment:

Abstract

The invention belongs to a microwave irradiation treatment subsystem and particularly relates to a high-power-resistant electric field mode stirring device. Metal fan blades (1) are driven by a motor (4); the motor (4) is connected with the metal fan blades (1) through a non-metallic transmission rod (2); a through-wall circular waveguide (3) is connected with a shielding compartment through a flange structure. According to the high-power-resistant electric field mode stirring device, the inner electromagnetic field mode is disturbed to obtain periodic change due to periodic operation of a metal fan; wave peaks and wave troughs are alternated, so that the uniformity of the radiation can be achieved.

Description

technical field [0001] The invention belongs to a microwave irradiation treatment subsystem, in particular to a high-power-resistant electric field mode stirring device. Background technique [0002] Logs are one of the most important imported commodities in my country. A large amount of log imports hides the problem of the spread and control of alien harmful organisms brought about by the import of logs, that is, the problem of quarantine treatment. In the past, the world-wide quarantine treatment method mainly used the chemical agent methyl bromide for fumigation. At present, domestically imported container logs are also treated with chemical methyl bromide fumigation technology. There are three main disadvantages in this treatment method. One is that methyl bromide is a toxic gas, which will cause serious air pollution, especially the destruction of the ozone layer; Methyl bromide will cause harm to the health of personnel and does not meet the occupational health requir...
