[0038] Working principle and working process:

[0039] Purification reaction process:

[0040] Raw material addition: First, graphite raw material is added into the purification reaction tank 2 through the feed port.

[0042] Purification and Filtration: The stirred and mixed graphite slurry enters the filtration area through the feed port 19, passes through the coarse filter layer 27, the fine filter layer 28, and the activated carbon filter layer 29 in sequence to remove impurities and organic matter. The purified graphite slurry is discharged through the discharge port 20 and enters the drying tank 3.

[0043] Drying process:

[0044] Spreading graphite slurry: The purified graphite slurry enters the drying tank 3 through the drop port 22. Start the rotary motor 27 to drive the scraper 25 to rotate and evenly spread the graphite slurry on the bottom surface of the tank body 2.

[0045] Hot air drying: The hot air drying cycle system 10 is activated to blow hot air into tank 2 to dry the graphite slurry. The hot air circulates within tank 2, improving drying efficiency. Simultaneously, a humidity sensor 23 monitors the humidity within the tank in real time. When the humidity reaches a set value, the control system shuts down the hot air drying cycle system 10 to prevent overdrying.

[0046] Product discharge: The dried graphite product is discharged through the discharge port 30 and the discharge pipe 8 for subsequent processing and treatment.
