s2: while the rotary cylinder (2) rotates centrifugally, the cylinder wall of the rotary cylinder (2) sequentially and repeatedly passes through the cleaning spray pipe (7), the cleaning spray pipe (7) washes the wall body of the rotary cylinder (2), the washed muddy water solution enters the mud receiving water tank (6), the muddy water solution in the mud receiving water tank (6) is discharged into the liquid collecting tank (5) from the bottom end, meanwhile, the water solution centrifugally dewatered by the rotary cylinder (2) is collected by the cylinder (3) and discharged into the liquid collecting tank (5), and the collected muddy water solution is precipitated and filtered in the liquid collecting tank (5) to obtain an upper clear water solution and a lower sludge layer;
s3: the sludge on the lower layer in the liquid collecting box (5) is input to a feed inlet of the rotary cylinder body (2) through a slurry pump, and the clear liquid on the upper layer in the liquid collecting box (2) is conveyed to an inner cavity of the cleaning spray pipe (7) through a water pump and circulates in a reciprocating mode.
