[0026] The transmission mechanism 9 includes a transmission shaft 901, a slide groove 902, a spring 903, a plug-in block 904, a transmission block 905 and a plug-in hole 906.

[0027] Specifically, the mixed low-density aerogel coating is added into the centrifugal barrel 6 through the feeding port 7, and then the power mechanism 4 works. At this time, the centrifugal barrel 6 can be driven to rotate with the cooperation of the rotating cylinder 8. As the centrifugal barrel 6 rotates, the low-density aerogel coating inside the centrifugal barrel 6 can be centrifuged, so that the impurities in the low-density aerogel coating can be separated, which is beneficial to improving the quality of the low-density aerogel coating.
