The invention discloses a microwave transmission system used for a microwave heating system. The microwave transmission system comprises a cylindrical microwave heating chamber (1) and microwave transmission waveguides (2) which are symmetrically installed at two sides of the cylindrical microwave heating chamber (1). The microwave transmission waveguides (2) are connected with E surface waveguides (3). The connection parts between the cylindrical microwave heating chamber (1) and the microwave transmission waveguides (2) are provided with microwave feed ports, waveguide end plates (4) are installed on the microwave feed ports, medium windows (5) are installed on the waveguide end plates (4), and the waveguide end plates (4) are connected with the microwave transmission waveguides (2). The microwave transmission system has the advantages that the structure design is reasonable, the microwave radiation is high in efficiency and uniform, the heating efficiency is high, the installation is convenient, a sparking phenomenon is avoided, the burning risk of materials in a microwave heating process is reduced, the microwave standing-wave ratio is mall, and the practicality is high.
Description
technical field [0001] The invention relates to the technical field of microwave heating system supporting equipment, in particular to a microwave transmission system used in a microwave heating system. Background technique [0002] Waveguide slot antennas generally include rectangular waveguide slot antennas, rectangular ridge waveguide slot antennas, circular waveguide slot antennas, elliptical waveguide slot antennas, and coaxial waveguide slot antennas. The difference in shape determines that they have their own performance and use. Commonly used slot antennas are broad-side longitudinal slots and narrow-side oblique slots. The commonly used form of the slit antenna is the microwave feeding method for heating materials in the prior art. The slit antenna is usually used in the form of a wide-side longitudinal slit and a narrow-side oblique slit. Under the same circumstances, the latter has twice as many radiation units as the former. , the radiation efficiency is higher...
