Description

Technical Field

[0001] This utility model relates to the field of aerogel drying technology, specifically an aerogel atmospheric pressure drying oven. Background Technology

[0002] Aerogels are nanoscale porous solid materials formed by replacing the liquid phase in a gel with gas through a sol-gel process and a specific drying method. Atmospheric pressure drying is one such method for aerogel production. It involves replacing the pore solution in the wet gel with one or more low-surface-tension solvents and modifying the gel surface to be hydrophobic, preventing excessive shrinkage, deformation, and structural damage during drying. This reduces or eliminates aerogel fragmentation and improves production quality.

[0003] In response, Chinese utility model patent CN222438369U discloses an atmospheric pressure drying device for rice husk-based silica aerogel, belonging to the field of aerogel drying technology. The device includes a container platform with a water tank fixedly connected to it. A drying chamber is located at the upper end of the container platform, and a rotating assembly is mounted on the drying chamber. A stirring blade is fixedly connected to the rotating assembly, and the stirring blade is located inside the drying chamber. This utility model solves the problem that existing atmospheric pressure drying devices for rice husk-based silica aerogel are inconvenient for simultaneously drying silica aerogel raw materials of different specifications, reducing the drying efficiency of the silica aerogel raw materials and significantly decreasing practicality.

[0004] The cover and rotating assembly of the aerogel atmospheric pressure drying device are located at the top of the drying chamber, which is placed in the placement slot. After the raw material is dried, the cover and rotating assembly need to be manually removed before the drying chamber can be taken out, which is quite laborious.

[0005] Therefore, we propose an aerogel atmospheric pressure drying oven to solve the above problems. Utility Model Content

The discharge pipe 30 is fixedly installed at the bottom of the collection frame 20, and a valve 31 is provided on the discharge pipe 30.

[0019] Example 2: Please see Figure 1-6 This is the second embodiment of the present invention. Based on the previous embodiment, the placement groove 10 and the through hole 9 are internally connected. Positioning rods 13 are fixed to both ends of the bottom surface of the drying tank 12. Positioning grooves 11 are opened at both ends of the bottom surface of the placement groove 10. The positioning rods 13 are engaged with the positioning grooves 11 to position the drying tank 12 and prevent the drying tank 12 from rotating.

[0020] Guide rods 27 are fixedly connected to both ends of the top surface of the movable block 23. A limiting circular plate 28 is fixedly connected to the top of the guide rods 27.

A suitable amount of water is injected into the water-holding frame 5 via the water injection pipe 7. The heating pipe 6 is connected to an external power source; activating the heating pipe 6 heats the water in the water-holding frame 5. Next, the aerogel material to be dried is added to the drying tank 12. The cylinder 1 21 is connected to an external power source; activating the cylinder 1 21 moves the moving block 23 horizontally to a designated position. Then, the cylinder 25 is connected to an external power source; activating the cylinder 25 moves the connecting plate 19, the tank cover 14, the motor 16, the stirring shaft 17, and the stirring rod 18 down to a designated position, causing the sealing gasket 15 on the bottom of the tank cover 14 to contact the top surface of the drying tank 12. The hot air from the heated water passes through the through-hole 9 to heat and dry the aerogel material in the drying tank 12. Simultaneously, the motor 16 is connected to an external power source. By starting the motor 16, the stirring shaft 17 and stirring rod 18 can be rotated to stir the aerogel raw material in the drying tank 12.
