Embodiment Construction

[0011] Such as figure 1 As shown, a rotary dynamic seal type microwave leakage prevention device includes a microwave source cavity 1 mounted on a frame, a rotatable material conveying roller 6 passing through the middle of the microwave source cavity, and the material conveying roller 6 passes through The sleeve 7 sleeved on its outer surface is installed in cooperation with the microwave source cavity 1 . Outside the sleeve 7, it is located at both ends of the microwave source cavity, and along the axial direction of the drum, an annular reactive leak composed of a combination of a cut-off waveguide leakage energy suppressor 2 and a 1 / 4 waveguide groove suppressor 3 is installed sequentially from the inside to the outside. An energy suppressor, an annular resistive energy leakage suppressor composed of a wave-absorbing filler ring 4 and a wave-absorbing sealing ring 5; one side of the annular reactive energy leakage suppressor and the outer end side plate of the microwave so...

Abstract

The invention relates to a rotary motive seal type microwave leakage prevention device which comprises a microwave source cavity (1) and a material conveying roller (6), wherein the microwave source cavity (1) is installed on a rack; the rotatable material conveying roller (6) transversely passes through the middle of the microwave source cavity; the material conveying roller (6) is in matched installation with the microwave source cavity (1) by a sleeve (7) which is sheathed on the external surface of the material conveying roller (6); an annular reactive energy leakage suppressor and an annular resistive energy leakage suppressor are subsequently sheathed from inside to outside; one side of the annular reactive energy leakage suppressor is connected with a side plate at the external end of the microwave source cavity; a wave absorption filler ring (4) is installed in the annular reactive energy leakage suppressor and is pressed by a junk ring (8); the annular reactive energy leakage suppressor is connected with the junk ring; a wave absorption seal ring (5) is installed in the junk ring (8); the annular reactive energy leakage suppressor, the annular resistive energy leakage suppressor and the junk rings form a microwave leakage prevention structure. According to the device provided by the invention, the microwave seal of rotary microwave drying equipment can be realized, and the microwave leakage quantity can be effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of microwave drying equipment mechanism. Background technique [0002] At present, the structural types of microwave drying equipment commonly used in industry include box type, cavity type, tunnel type, etc. The microwave oven cavity of these microwave drying equipment is a fixed structure. Mature. However, for the rotary microwave drying equipment that needs to rotate the cavity of the microwave oven, since the cavity of the microwave oven used to transport the material has a relative rotational movement relative to the microwave source, it cannot be completely sealed, and it is difficult to effectively prevent microwave leakage. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, to provide a rotary dynamic sealing type microwave leakage prevention device, which is used for the rotary microwave drying equipment whose cavity of the ...
