and 3, step 3: a material level meter (4-2) positioned in the granule feeding chamber (4-1) monitors the height of the granule material level in real time; when the level indicator (4-2) detects that the level of the granular materials is higher than a system set value L1, the level indicator (4-2) sends an electric signal I to the control system (9), the control system (9) reduces the rotating speed of the crushing motor (2) after receiving the electric signal I, and simultaneously increases the rotating speed of the compression motor (6); when the level indicator (4-2) detects that the level height of the granular materials is lower than a system set value L2, the level indicator (4-2) sends an electric signal II to the control system (9), and the control system (9) increases the rotating speed of the crushing motor (2) and reduces the rotating speed of the compression motor (6) after receiving the electric signal II;

And 4, step 4: the control system (9) simultaneously starts the transmission motor (4-5-10), the water feeding pump, the chemical feeding pump and the stirring motor (4-5-5), the mixture of uncompressed granules and water downwards enters the stirring barrel (4-5-12) through the liquid inlet buffer plate (4-5-11), meanwhile, clear water injected by the cleaning ring pipe (4-5-9) enters the stirring barrel (4-5-12) along with the mixture and rotates under the drive of the stirring blades (4-5-8), so that the mixture of granules and water is uniformly mixed with the chemical uniformly sprayed in the stirring barrel (4-5-12), and the mixture mixed with the chemical enters the buffer chamber (4-5-6) through the mud buffer plate (4-5-7) to enable the chemical and the water to fully react, the mixture after reaction is fully stirred downwards by the rotation of a stirring wheel (4-5-4) through a through hole plate (4-5-1), the precipitate enters a bottom sludge settling chamber (4-5-2) through a bottom sludge settling buffer plate (4-5-3) for settling after the mixture is stirred, and clear water is discharged through a clear water discharge pipe (4-5-13);

and 5, step 5: a slag water liquid level meter (4-7) positioned in the filtrate separation chamber (4-5) monitors the slag water liquid level condition in the filtrate separation chamber (4-5) in real time; when the slag water liquid level meter (4-7) detects that the slag water liquid level in the filtrate separation chamber (4-5) is higher than a system set value, the slag water liquid level meter (4-7) sends a feedback signal to the control system (9), the control system (9) opens the slag discharge pipe (4-8) after receiving the feedback signal, and the slag water is discharged through the slag discharge pipe (4-8).
