Abstract
The utility model relates to a multistage belt type non-leakage microwave drying machine which comprises a shell, a material conveying belt device, a feeding device, a discharging device and a plurality of microwave generators. The material conveying belt device is mainly composed of a drive wheel, an inner guiding wheel, an outer guiding wheel and a conveying belt. The conveying belt between the drive wheel and the inner guiding wheel is in step type transmission. The position where the conveying belt penetrates through the shell is provided with a choke groove. The choke groove is a rectangular cylinder body. One side wall of the cylinder body is provided with a long groove, the length of the long groove is larger than the width of the conveying belt, and the choke groove is fixedly connected with the shell through the side wall adjacent to the long groove. The long groove is arranged downwards. According to the multistage belt type non-leakage microwave drying machine, the choke groove is formed in an opening of the shell, and due to the reflex action of the choke groove, microwaves which will be possibly leaked and radiated to an inlet and outlet opening are reflected to materials or returned into a drying bin, that is a microwave action area is completely shielded in the drying machine. Thus, the utilization rate of microwave energy is improved.
