[0041] like Figure 1 and Figure 2 The air supply box 1, the air drying box 3 and the exhaust box 2 have the same outer circumferential dimensions, and their outer side walls are flush and completely fitted when they collide with each other. The air supply box 1 and the adjacent air drying box 3 are detachably fixedly connected via a first connecting component 15, and each adjacent air drying box 3 is detachably fixedly connected via a second connecting component 16, and the exhaust box 2 and the adjacent air drying box 3 are detachably fixedly connected via a third connecting component 17.

[0042] like Figure 1 and Figure 2After the staff selects a suitable number of air-drying boxes 3, they move the suitable number of air-drying boxes 3 to suitable positions and arrange them evenly and conflict with each other. Then, they place the air supply box 1 and the exhaust box 2 on both sides of the air-drying boxes 3 respectively and make the air supply box 1 and the exhaust box 2 conflict with each other, and they are fixedly connected through the first connecting component 15, the second connecting component 16 and the third connecting component 17 to facilitate the air-drying work.

[0043] like Figure 4 and Figure 5 The first connecting component includes a first mounting plate 1501 fixed on the outer wall of the air supply box 1, and a guide column 1502 is integrated in the middle position of the first mounting plate 1501 away from the air supply box 1.

The slide 1503 is sleeved on the outside of the guide column 1502 through the waist-shaped groove 1504 and is slidably connected with the guide column 1502. The part of the guide column 1502 that passes through the slide 1503 is fixed with an anti-drop block slidably connected with the slide 1503, and the slide 1503 will not fall off from the outside of the guide column 1502. A second mounting plate 1501 is fixed on the outer wall of the adjacent air-drying box 3. Plate 1505, a clamping block 1506 is fixed on the side of the second mounting plate 1505 facing away from the air-drying box 3, and a through hole 1507 adapted to the slide 1503 is formed on the clamping block 1506, and the slide 1503 passes through the clamping block 1506 through the through hole 1507, and a cylindrical hole is formed at the end of the slide 1503 passing through the clamping block 1506, and a threaded hole 1508 located beside the cylindrical hole is formed on the outer wall of the adjacent air-drying box 3, and a screw 1509 is passed through the cylindrical hole, and the screw 1509 passes through the slide 1503 through the cylindrical hole, and the part of the screw 1509 passing through the slide 1503 enters the threaded hole 1508 and is threadedly connected with the threaded hole 1508, and the first connecting component, the second connecting component 16 and the third connecting component 17 have the same structure.

[0044] like Figure 4 and Figure 5 When connecting, grab the slide 1503 and push it manually so that the slide 1503 passes through the through hole 1507 and the clamp 1506, and the slide 1503 moves to the outside of the threaded hole 1508. The screw 1509 passes through the cylindrical hole and is inserted into the threaded hole 1508 and is threadedly connected to it, so as to facilitate the fixed connection of the air supply box 1, the air drying box 3 and the exhaust box 2.

By setting the rubber sealing rings, when the air supply box 1, the air drying box 3 and the exhaust box 2 conflict with each other, the connection is sealed, reducing the air discharged from the connection gap between the air supply box 1, the air drying box 3 and the exhaust box 2, affecting the drying effect.

[0046] like Figure 8 The inner cavity of the air-drying box 3 is hollow and has openings on both sides. A number of evenly arranged support plates 18 are fixed in sequence from top to bottom in the inner cavity of the air-drying box 3. A mold 19 for accommodating the aerogel composite insulation board is placed on each support plate 18. A groove adapted to the mold 19 is provided on the side of the support plate 18 facing the mold 19.

In order to improve the air-drying effect of the mold 19, the outer side wall and the bottom of the mold 19 are provided with a plurality of ventilation holes 21 connecting the outside and the receiving groove 20. The support plate 18 is also provided with a plurality of exhaust holes adapted to the ventilation holes 21.

[0048] like Fig. 9 and Fig.10 When the aerogel composite insulation board is placed in the receiving groove 20 of the mold 19 and the mold 19 is placed on the support plate 18, the air contacts the bottom and surrounding side walls of the aerogel composite insulation board in the receiving groove 20 through the exhaust holes and the ventilation holes 21, thereby improving the drying effect of the device.

[0049] like Fig. 9 and Fig.10 In order to reduce the possibility of unformed aerogel composite insulation board material in the mold 19 overflowing through the ventilation hole 21 or affecting the molding, a circular ventilation groove 22 located outside the accommodating groove 20 and a square ventilation groove 24 located at the bottom of the accommodating groove 20 are opened on the mold 19. The circular ventilation groove 22 and the square ventilation groove 24 are both connected to the accommodating groove 20 through the ventilation hole 21. The circular ventilation groove 22 is plugged and connected with a circular closing plate 23 that is adapted to the circular ventilation groove 22 and closes the ventilation hole 21.

[0051] Grab the slide 1503 and push it manually, so that the slide 1503 passes through the through hole 1507 and the clamp 1506, and the slide 1503 moves to the outside of the threaded hole 1508, and the screw 1509 passes through the cylindrical hole and is inserted into the threaded hole 1508 and is threadedly connected thereto, so as to facilitate the fixed connection of the air supply box 1, the plurality of air drying boxes 3 and the exhaust box 2;

[0052] Turn on the air intake fan 8 and the blower 14, and the outside air enters the air supply box 1, the air drying boxes 3 and the exhaust box 2 in sequence, and is discharged through the exhaust pipe 12. At the same time, the air passes through the air intake filter frame 7, the air intake filter plate, the exhaust filter frame 9, and the exhaust filter plate 10 in sequence, filtering the gas entering the air drying box 3 and the gas discharged from the air drying box 3, thereby improving the safety and hygiene of the device;

[0053] The air supply box 1 and the exhaust box 2 cooperate to form air convection, which helps to keep the air in the air drying box 3 fresh and clean, and at the same time accelerates the heat dissipation, thereby improving the drying efficiency of the aerogel composite insulation board;

The air contacts the bottom and the surrounding side walls of the aerogel composite insulation board in the receiving groove 20 through the exhaust hole and the ventilation hole 21, thereby improving the drying effect of the device and reducing the drying time.
