Embodiment 1

[0039] Such as figure 1 As shown, the present invention provides a drying system, which includes at least a first-stage dryer 1 and a second-stage dryer 2. The first-stage dryer 1 is used to perform the first-stage drying treatment on the composite aerogel self-insulating template 8. The second-stage dryer 2 is used to perform a second-stage drying treatment on the composite aerogel self-insulating template 8. Specifically, the first-stage dryer 1 has at least a first inlet 101 and a first outlet 102. The second-stage dryer 2 has at least a second inlet 201 and a second outlet 202. The composite aerogel self-insulation template 8 can enter the first-stage dryer 1 from the first inlet 101, and is discharged from the first outlet 102 after the first-stage drying process is completed. The composite aerogel self-insulating template 8 after the first-stage drying treatment can enter the second-stage dryer 2 through the second inlet 201 for the second-stage drying treatment. The c...

Embodiment 2

[0045] This embodiment is a further improvement of Embodiment 1, and the repeated content will not be repeated.

[0046] Such as image 3 As shown, the second-stage dryer 2 at least includes a housing 204, a clamping mechanism 205, a blowing mechanism 206, and a first conveying mechanism 207. The second inlet 201, the second outlet 202 and the second air outlet 203 are all provided on the housing 204. The clamping mechanism 205 is used to clamp the composite aerogel self-insulation template, so that the composite aerogel self-insulation template can be partially suspended. Specifically, the clamping mechanism 205 can clamp the first end of the composite aerogel self-insulating template, thereby making the second end of the composite aerogel suspended. For example, such as image 3 As shown, the clamping mechanism 205 can clamp the left end of the composite aerogel self-insulating template, thereby making the right end of the composite aerogel self-insulating template in a susp...

Embodiment 3

[0052] This embodiment is a further improvement of the foregoing embodiment, and the repeated content will not be repeated.

[0053] Preferably, the second-stage dryer 2 is configured to form a first air flow 9 and a second air flow 10 with different flow rates and alternate flow rates on both sides of the composite aerogel self-insulating template 8 to form alternate pressures. Therefore, the composite aerogel self-insulating template 8 can realize the first-stage air-drying treatment in a manner of presenting a swing state based on the pressure difference. Specifically, the drying system further includes a control box 11. Both the first blower 7a and the second blower 7b are connected to the control box 11, so that the control box 11 can control the first blower 7a and the second blower 7b to realize the first-stage air drying process. The control box 11 is configured to control the second-stage dryer to perform the first-stage air drying treatment in the following manner:

Abstract

The invention relates to a drying system for preparing a composite aerogel self-insulation template. The drying system comprises a first-stage dryer and a second-stage dryer, under the condition thatthe composite aerogel self-insulation template completes first-stage drying treatment according to a drying mode, the composite aerogel self-insulation template can complete second-stage drying treatment according to the air drying mode; the second-stage dryer is configured to: when alternately-changed pressure difference is formed on the two sides of the composite aerogel self-insulation templateaccording to the mode of forming first airflow and second airflow which are different in flow speed and alternately changed in flow speed, the composite aerogel self-insulation template can achieve first-stage air drying treatment in the mode that the composite aerogel self-insulation template is in a swing state based on the pressure difference; when the first air flow and the second air flow with the same flow velocity are formed on the two sides of the composite aerogel self-insulation template, the composite aerogel self-insulation template can achieve second-stage air drying treatment inthe mode that the composite aerogel self-insulation template is kept in a flat and straight state parallel to the ground.

Description

Technical field [0001] The invention belongs to the technical field of drying equipment, and particularly relates to a drying system for preparing a composite aerogel self-insulating template. Background technique [0002] Aerogel refers to a nanoporous material extracted by supercritical technology. It contains a large amount of air inside. The porosity can reach 99.8% and the specific surface area can reach 200m. 2 ~1000m 2 / g, the pore diameter is 5-20nm, the density of aerogel is extremely low, the smallest can reach 3kg / m 3 . Its unique microscopic nanostructure makes it obviously different from the corresponding glass state in mechanical, acoustic, optical, thermal and other properties. Aerogel is a material with comprehensive properties such as heat insulation, fire protection, sound absorption, explosion protection, and shock absorption. The composite aerogel self-insulation template is a flexible thermal insulation felt that combines nanoporous aerogel materials and fib...
