[0024] like Figure 1-5 As shown, a drying box includes a box body 1, the box body 1 has a accommodating cavity 2 for placing a graphite boat, and also includes a negative pressure device 3. The box body 1 is provided with a microwave generating device 4 for microwave heating of materials on the graphite boat in the accommodating cavity 2, and the box body 1 is provided with a door panel 5 on the open end cover of the accommodating cavity 2. The negative pressure device 3 is connected to the box body 1 and is used to discharge water vapor in the box body 1 out of the box body 1. In this embodiment, the negative pressure device 3 is an exhaust fan, and the input end of the exhaust fan is connected to the box body 1 through a pipeline.

[0025] In the present embodiment, sixteen microwave generating devices 4 are provided and are arranged on both sides of the box body 1 opposite to each other, with eight on each side and divided into two layers, each layer having four microwave generating devices 4, and the microwave generating devices 4 on each side are arranged along the length direction of the graphite boat. In another implementation mode, microwave generating devices 4 are arranged on the four outer surfaces of the front, back, left and right sides of the box body 1, and are also arranged on the bottom of the box body 1, and the microwave generating devices 4 are arranged according to the specifications of the oven.

[0026] The opening end of the accommodating chamber 2 is set upward, and the door panel 5 is hinged on the box body 1. There are two door panels 5 and they are arranged opposite to each other. The box body 1 is provided with a driving mechanism 6 for driving the door panel 5 to rotate. The driving mechanism 6 is a cylinder, and the cylinder is arranged one by one with the door panel 5. The cylinder is hinged on the box body 1, and a connecting rod 7 is hinged on the protruding end of the cylinder. One end of the connecting rod 7 is fixed on the rotation center axis of the door panel 5.

[0027] When the above drying box is loaded with a graphite boat, the cylinder at the driving mechanism 6 is first controlled to extend, and the extended end of the cylinder extends and drives the connecting rod 7, and the connecting rod 7 drives the door plate 5 to rotate on the box body 1 and open the accommodating chamber 2, and then the graphite boat is loaded with materials to be dried, and the graphite boat is hoisted into the box body 1 by an external crane, and then the extended end of the cylinder at the driving mechanism 6 is retracted, and the door plate 5 is controlled to close the accommodating chamber 2, and the loading of the graphite boat is completed;

[0028] During drying, the microwave generator is started, and the microwave generators on the front and rear sides of the box body 1 emit microwaves and dry the materials on the graphite boat.
