[0027] By adopting the above technical scheme, when the fine sanding machine works, the fine powder collecting pipe 11 extracts the generated sand powder by negative pressure, and then transports to the fine powder material dust collector 13 for dust removal through the fine powder material conveying pipe 12 and the first material suction pipe 18. After the clean air is extracted by the first fan pipe 15 and the fine material suction fan 16, it is discharged through the first exhaust pipe 17. The powder in the fine powder material dust collector 13 is collected into the fine powder collecting box 14, realizing the collection of fine powder for subsequent reuse.

[0028] In the embodiment, the coarse sand recovery system 2 includes a second material suction pipe 215. The second material suction pipe 215 is connected to the inlet end of a cyclone centrifuge 23. The outlet end of the cyclone centrifuge 23 is connected to the suction end of a powder suction fan 213 through a centrifuge air material pipe 211. The outlet end of the powder suction fan 213 is connected to a dust collector 212 through a pipe. The dust collector 212 is provided with a dust collecting box 214 below.

[0029] Further, the second material suction pipe 215 is connected to a coarse powder conveying pipe 22 at one end away from the cyclone centrifuge 23.

A material distribution valve 24 is installed at the bottom of the cyclone centrifuge 23. The coarse powder collecting box 210 is provided below the material distribution valve 24.

[0030] By adopting the above technical scheme, when the coarse sanding machine works, coarse powder is generated. The coarse powder collecting pipe 21 extracts the coarse powder by negative pressure. Then, the coarse powder is transported to the cyclone centrifuge 23 for centrifugal treatment through the coarse powder conveying pipe 22 and the second material suction pipe 215. The light powder is transported to the dust collector 212 for dust removal through the centrifuge air material pipe 211 under the extraction of the powder suction fan 213.
