2. According to the invention, the rotating motor is controlled by the numerical control program to drive the spin-drying drum to rotate rapidly, so that the gravity ball drives the movable rod to move in a direction away from the center of the spin-drying drum under the action of centrifugal force, the waste chip layer stacked on the movable rod loses the restriction of the movable rod and loosens, at the moment, the waste chip layer is tightly attached to the inner side wall of the spin-drying drum under the action of the centrifugal force, the cooling liquid adhered on the waste chip layer is separated from the waste chip layer under the action of the centrifugal force, and the cooling liquid in the spin-drying drum is discharged from the liquid Kong Feichu through the centrifugal force, so that the waste chip and the cooling liquid are separated secondarily.

3. According to the invention, the cooling liquid flies out of the spin-drying drum and then is beaten on the inner wall of the outer sleeve, so that the cooling liquid carried with fine scraps on the inner wall of the outer sleeve moves downwards and is absorbed by the sponge block, meanwhile, the spin-drying drum drives the gravity ball far away from the spin-drying drum to synchronously rotate when rotating, so that the gravity ball intermittently extrudes the sponge block, the sponge block continuously extrudes the cooling liquid absorbed by the sponge block to keep enough space to absorb other cooling liquid, and meanwhile, the cooling liquid finally breaks away from the sponge block and flows to the bottom of the outer sleeve to be discharged, and the scraps are absorbed by the sponge block, so that the cooling liquid with the fine scraps is separated for the third time through the sponge block.
