[0035] Reference Figures 1-2 The feeding pipe of the grinding box 17 is fixedly connected to a second vacuum feeder 30. The lower surface of the second vacuum feeder 30 is fixedly connected to a transition hopper 31. The lower surface of the transition hopper 31 is fixedly connected to the upper surface of the fixed frame 1. The feeding pipe of the transition hopper 31 is fixedly connected to the inside of the screening box 10. The feeding pipe of the screening box 10 is fixedly connected to a third vacuum feeder 32.

The outer wall of the filling machine 37 is fixedly connected to the inner wall of the fixed frame 1.
[0036] Specifically, by activating the second vacuum feeder 30, the aerogel powder ground in the grinding chamber 17 can be transferred to the transition hopper 31 via the conveying pipe. The fixing frame 1 provides fixed support for the transition hopper 31, and the transition hopper 31 can discharge its internal aerogel powder into the screening box 10 for multi-stage screening via the discharge pipe. After multi-stage screening, by activating the third vacuum feeder 32, the aerogel powder in the screening box 10 can be processed via the conveying pipe. The aerogel powder is transferred to the finished product silo 33 for storage. The fourth vacuum feeder 34 can then transport the aerogel powder in the finished product silo 33 to the filling silo 35 for filling preparation via a conveying pipe. The filling silo 35 provides fixed support for the vacuum machine 36, and the vacuum machine 36 can reduce dust generation during the filling process of the powder by the filling machine 37, maintain a clean working environment, and avoid problems such as loose sealing and leakage caused by residual air during the sealing process.
[0037] Working principle: When the equipment is needed, firstly, the first vacuum feeder 15 is turned on. The first vacuum feeder 15 can transfer the aerogel to be processed in the storage bin 38 to the feeding bin 16 through the conveying pipe. Then, the discharge pipe of the feeding bin 16 can transfer the aerogel to the grinding box 17 and then to the vibrating screen 21. After that, the third motor 25 is turned on. The output end of the third motor 25 can drive the first bevel gear 26 to rotate on the inner wall of the fixed box 24. The fixed box 24 can drive the second bevel gear 27 to rotate through meshing connection. Then, the second bevel gear 27 can drive the rotating shaft 28 to rotate through the slide bar on the outer wall of the rotating shaft 28, thereby driving the grinding plate 29 to vibrate. The aerogel inside the vibrating screen 21 is ground, and simultaneously the second motor 18 is turned on. The output of the second motor 18 can drive the transmission shaft 19 to rotate. In turn, the transmission shaft 19 can drive the vibrating screen 21 to slide up and down on the inner wall of the grinding box 17 via the crank 20. Thus, the vibrating screen 21 can drive the horizontal plate 22 to slide on the inner wall of the grinding box 17. The second spring 23 can make the vibrating screen 21 vibrate. At this time, the vibrating screen 21 can drive the rotating shaft 28 to slide up and down inside the second bevel gear 27 to ensure the grinding space during vibration, increase the collision frequency and force between the aerogel powder particles and the grinding media, and then the ground aerogel powder is passed through... The vibrating screen 21 falls to the bottom of the inner wall of the grinding box 17. Then, the second vacuum feeder 30 transfers the aerogel powder to the transition hopper 31 through the conveying pipe. The discharge pipe of the transition hopper 31 then discharges the aerogel powder into the screening box 10 for screening. The first motor 5 is turned on. The output end of the first motor 5 can drive the rotating disk 4 to rotate inside the support plate 3 fixed to the outer wall of the support leg 2, so as to synchronously drive the top blocks 6 at both ends to revolve. When the upper surface of the top block 6 contacts and disengages from the roller 7, the connecting column 8 can be driven by the roller 7 to slide up and down inside the screening box 10, thereby driving the screen plate 9 to slide on the inner wall of the screening box 10. At the same time, the side plate 11 can... The aerogel powder on the sieve plate 9 is sieved by the vibration of the first spring 14 on the partition plate inside the layered frame 13, thereby achieving fine particle size classification and helping to obtain products with specific and precise particle size ranges. Then, the third vacuum feeder 32 can transport the aerogel powder of different grades in the screening box 10 to the interior of the finished product silo 33 through the conveying pipe. Then, the fourth vacuum feeder 34 can transport the aerogel powder in the finished product silo 33 to the filling silo 35 through the conveying pipe. The filling silo 35 is filled with aerogel powder by the filling machine 37, and the vacuum machine 36 can ensure the vacuum environment during filling to prevent dust from scattering and ensure filling quality.
