The surface of the pressure plate 5 is evenly provided with There are through holes of the same size. During the drying process, the top and bottom fans 10 and heating rods 8 can be turned on through the control box 7. By pressing the operation button of the control box 7, the main board inside the control box 7 transmits the corresponding electrical signal to all the heating rods 8 and fans 10 according to the operation signal of the operation button. The heating rods 8 are powered on and heated by resistance to release heat. The fans 10 are powered on and started. The rotating fan of the fan 10 blows airflow to the heating rods 8 that release heat. The airflow drives the hot air around the heating rods 8 and dries the aerogel on the top surface of the conveyor belt 12. Through the cooperation of the upper and lower fan groups 10 and the heating rods 8 groups, the aerogel on the top surface of the conveyor belt 12 can be dried by the hot air from top to bottom, so that the bottom and top surfaces of the hot gel are synchronized. Drying and heating, so that the hot gel is heated more evenly. When the aerogel is subjected to excessive airflow from the bottom fan 10, the pressure plate 5 on the top of the conveyor belt 12 will block the aerogel to prevent the aerogel from being blown upward by the excessive wind force of the fan 10, causing the aerogel to fly everywhere. During use, the control box 7 can be raised according to the thickness of the aerogel to control the height of the pressure plate 5 to adapt to aerogels of different thicknesses. When the operation button of the control box 7 is pressed, the main board inside the control box 7 will transmit the first electrical signal to the hydraulic pump 4 according to the operation information of the operation button. The hydraulic pump 4 transports or absorbs the hydraulic oil inside the hydraulic cylinder 3 through the hydraulic pipe, so that the hydraulic cylinder 3 moves downward or upward. Since the bottom end of the hydraulic cylinder 3 is fixed to the top surface of the pressure plate 5 by the fixing bolt 11,In this way, when the hydraulic cylinder 3 moves up and down, it will drive the pressing plate 5 to move up and down to adapt to aerogels of different thicknesses. During the movement of the pressing plate 5 up and down, the guide rod 2 on the left side of the dryer 1 will assist the movement of the pressing plate 5, so that the pressing plate 5 can move up and down normally.

[0027] The use process of the dryer 1 is as follows: first, the wet aerogel is placed on the top surface of the conveyor belt 12 inside the dryer 1, and the operation button of the control box 7 is used to control the start of the DC motor that can make the conveyor belt 12 run. The control box 7 receives the operation information of the operation button and transmits this information to the DC motor. The DC motor is powered on and started. The started DC motor drives the driving wheel 13 inside the conveyor belt 12 through the output shaft, and the conveyor belt 12 is driven by the rotation of the driving wheel 13. The driven wheel 14 on the side of the conveyor belt 12 away from the driving wheel 13 is used to support the other end of the conveyor belt 12 so that the conveyor belt 12 can run smoothly. When the conveyor belt 12 is running, the conveyor belt 12 drives the aerogel to move into the dryer 1. The fan 10 and the heating rod 8 inside the dryer 1 cooperate to transport the hot air to the bottom and top surfaces of the aerogel on the top surface of the conveyor belt 12, so that the aerogel can be dried. The dried aerogel is transported out of the dryer 1 again by the running conveyor belt 12 to complete the drying of the aerogel. Specific embodiment 2:
