A High-efficiency Waveguide Slot Antenna Array for Base Cloth Drying

Abstract

The invention discloses a high-efficiency waveguide slot antenna array for base cloth drying, comprising: several radiation waveguides and several isolation plates arranged at intervals in sequence, the radiation waveguides are connected through the isolation plates; the radiation waveguides are connected by the isolation plates; A magnetron is fixedly connected inside, and the magnetron is arranged at the bottom of the radiation waveguide; several longitudinal slits are opened on the upper surface of the radiation waveguide, and the adjacent longitudinal slits are arranged in left and right staggeredly, and the radiation waveguide The lower surface is provided with a circular hole; the upper surface of the waveguide slot antenna array is covered with a radome. The radiation waveguide required by the present invention is a non-standard waveguide. Compared with the prior art, the size is smaller, the addition and subtraction and assembly are easier, and the microwave energy uniformity of the drying surface of the base cloth is high, the drying effect is good, and the energy utilization is high. High rate, low processing deviation requirements.

Description

technical field [0001] The invention relates to the technical field of microwave heating and antennas, in particular to a high-efficiency waveguide slot antenna array used for base cloth drying. Background technique [0002] With the continuous improvement of the material level, people have more and more demands for clothing, hats and clothing, and the textile industry is also growing, and base cloth drying is an important part of the textile industry that cannot be ignored. Drying of base fabrics. Throughout the field of base cloth drying, at present, the mainstream textile industry drying equipment is divided into three categories, namely steam drying equipment, infrared drying equipment and microwave drying equipment. [0003] Steam drying equipment is the mainstream textile drying equipment in the market, which uses the principle of heat conduction. The water vapor is transmitted to the inside of the box through the pipeline, and the high-temperature water vapor transf...
