When the graphite needs to be sintered, When the boat is drying, the operator takes out the upper cover 106 from the inside of the groove 105, and then places multiple graphite boats on the upper ends of multiple rope bodies 201 at equal distances in sequence, and flexibly supports them through the multiple rope bodies 201. Then, the upper cover 106 is placed in the inside of the groove 105, and the pressing plate 302 is manually rotated to the top of the upper cover 106. The electric push rod 301 drives the pressing plate 302 to slide downward, so that the lower end of the pressing plate 302 fits with the upper end of the upper cover 106, and the upper cover 106 is pressed tightly, thereby closing the inside of the drying tank 101. The microwaves emitted by the multiple microwave generators 102 are used to heat the boats. Microwaves dry the graphite boat, and the moisture and residue in the graphite boat can be quickly removed through the penetration and heating effect of microwaves. When the temperature inside the drying tank 101 needs to be adjusted, the blower conveys the external airflow to the inside of the air inlet pipe 111, and the airflow inside the air inlet pipe 111 is extracted through multiple output ends of the air inlet pipe 111. The extracted airflow flows into the drying tank 101 through multiple holes 112, thereby adjusting the temperature inside the drying tank 101. During the process of microwaves emitted by the microwave generator 102, the airflow flowing in the heat dissipation groove 103 dissipates heat for the microwave generator 102.
[0023] The generating end of the microwave generator 102 is located inside the drying tank 101, and the back of the microwave generator 102 is located inside the heat dissipation tank 103. A heat dissipation plate 104 is provided inside the heat dissipation tank 103. The microwave generator 102 is cooled by the cooperation between the flowing airflow and the heat dissipation plate 104 to prevent the microwave generator 102 from being damaged by high temperature.

The plurality of vertical rods 401 are distributed in a circular array. External air flows into the cavity 107 through the slot 109 .

[0028] In the present invention, when the graphite boat needs to be dried, the operator takes out the upper cover 106 from the inside of the groove 105, and then places multiple graphite boats in sequence and equidistantly on the upper ends of multiple rope bodies 201, and flexibly supports them through the multiple rope bodies 201. Then, the upper cover 106 is placed inside the groove 105, and the pressure plate 302 is manually rotated to above the upper cover 106. The electric push rod 301 drives the pressure plate 302 to slide downward, so that the lower end of the pressure plate 302 is in contact with the upper end of the upper cover 106, and the upper cover 106 is pressed tightly, thereby closing the inside of the drying tank 101.
[0029] The graphite boat is dried by microwaves emitted by the multiple microwave generators 102 . The penetration and heating effect of the microwaves can quickly remove moisture and residues in the graphite boat, thereby facilitating microwave drying of the graphite boat.
[0030] When the temperature inside the drying tank 101 needs to be adjusted, the blower delivers the external airflow to the inside of the air inlet pipe 111. The airflow inside the air inlet pipe 111 is dispersed and guided to the inside of the chamber 110 through multiple output ends of the air inlet pipe 111. The airflow inside the chamber 110 is further dispersed and flows to the inside of the drying tank 101 through multiple holes 112, thereby adjusting the temperature inside the drying tank 101.
[0031] During the microwave emission process of the microwave generator 102, the motor 402 drives the rod body 403 to rotate, and at the same time, the rod body 403 drives the multiple blades 404 to rotate to generate airflow. The external airflow flows into the cavity 107 through the slot 109. The airflow flowing inside the cavity 107 flows into the heat dissipation groove 103 through the multiple holes 108.
