[0043] Working principle: first, the flotation agent is injected into the flotation bin 2, and the air pump 701 is controlled to be turned on.

The movement of the exhaust pipe 704 drives the bubbles to move. The bubbles make the flotation agent adsorbed on the surface of the graphite particles to form foam. The graphite particles float to the surface of the slurry with the foam, while the iron impurities sink to the built-in baffle 3. The built-in baffle 3 is provided with a filter tank. Under the action of the bubbles, the iron slides to both sides along the built-in baffle 3 and is collected centrally. The driving shaft 602 rotates through the turntable 604 to drive the swing rod 505 to swing back and forth. The swing rod 505 drives the slide rod 502 to slide back and forth under the guidance of the guide rod 501 through the second sliding frame 504, and the graphite particles and foam are scraped and discharged from the discharge port through the scraper 503.
