[0029] In one embodiment, Figure 1-Figure 6 As shown, a device for separating impurities from aerogel comprises a separation water tank portion 100, an outer rod frame 200 and a separation shell 300, wherein the outer rod frame 200 is arranged on the side of the separation water tank portion 100, and an upper movable frame component 400 and a lifting cylinder portion 600 fixed thereon are arranged on the outer rod frame 200, wherein the telescopic end of the lifting cylinder portion 600 is connected to the upper movable frame component 400, and the top of the separation shell 300 is connected to the upper movable frame component 400 and the separation shell 300 comprises a cylinder portion 600 located on the upper movable frame component 400. The upper chamber 310 is located on the side, the separation chamber 320 is located in the middle and the lower chamber 330 is located at the bottom. The top of the upper chamber 310 is connected to the upper movable frame part 400 and the upper chamber 310, the separation chamber 320 and the lower chamber 330 are all connected. The separation chamber 320 is a cylindrical structure and a separation and collection component 340 and a positioning rotating rod shaft 350 are installed inside. The separation and collection component 340 includes a hollow main rod part 341 and two circular end plates 343 respectively arranged at both ends of the hollow main rod part 341. The hollow main A plurality of mesh panels 342 are arranged on the outer wall of the rod portion 341, and a trough portion 344 is formed between two adjacent mesh panels 342 and two circular end panels 343. The distance between the sides of the two adjacent mesh panels 342 away from the hollow main rod portion 341 is greater than the width of the upper chamber 310. The sides of the mesh panels 342 and the edges of the circular end panels 343 are in sealing contact with the inner wall of the separation chamber 320. The positioning rotating rod shaft 350 is rotatably arranged inside the separation chamber 320, and the axis of the positioning rotating rod shaft 350 is aligned with the center line of the separation chamber 320. Overlap; when the separation and collection component 340 is inside the separation chamber 320, the positioning rotating rod shaft 350 is inserted into the hollow main rod part 341, and the separation chamber 320 has an installation port at one end and the separation and collection component 340 can be pushed into or pulled out of the separation chamber 320 through the installation port; a separation stirring assembly 500 is also provided on the upper movable frame part 400 and the lower end of the separation stirring assembly 500 extends to the interior of the upper chamber 310, and the separation stirring assembly 500 is used to stir the water and aerogel inside the upper chamber 310.

Therefore, the impurities in the aerogel can be separated quickly and effectively and the material can be easily taken out. At the same time, the water used for separating the impurities can be reused. When the separation chamber 320 floats to the surface, the water also acts on the partition plate 342 and impacts the precipitated impurities attached to the surface of the partition plate 342, so that the precipitated impurities break away from the surface of the partition plate 342 and fall into the lower chamber 330.
