then the numerical control program controls the reciprocating mechanism assembly 5 again (a specific time interval can be set), the valve plate I7 closes the liquid inlet pipe 11 on the right side, the valve plate II 8 opens the liquid inlet pipe 11 on the left side, the cooling liquid mixed with the waste scraps enters the liquid inlet pipe 11 on the left side at the moment, the action is repeated, the drying drum 12 filled with the waste scraps and the cooling liquid on the right side is started under the control of the numerical control program, the rotating motor 16 below the drying drum is meshed with the transmission gear 18 through the driving gear 17, the drying drum 12 is rapidly rotated, the gravity ball 24 and the movable rod 21 are moved away from the center of the drying drum 12 under the influence of centrifugal force, the movable rod 21 is gradually separated from the filter layer formed by the waste scraps, the waste scraps are also moved towards the inner side wall of the drying drum 12 under the action of the centrifugal force at the moment, when the gravity ball 24 and the movable rod 21 are moved towards the outer sleeve 9, the space of the liquid storage cavity I201 is continuously enlarged, the space of the liquid storage cavity II 202 is continuously reduced, the liquid level in the liquid storage cavity II 202 gradually exceeds the height of the through hole 23 under the extrusion of the partition plate 22, the liquid level is continuously extruded into the liquid storage cavity I201 through the through hole, when the gravity ball 24 reaches the inner side wall of the outer sleeve 9, one end of the movable rod 21 positioned in the spin-drying drum 12 is close to the inner side wall of the spin-drying drum 12, the reset spring 25 is in a stretching state, meanwhile, the waste chips are attached to the inner side wall of the spin-drying drum 12, so that the cooling liquid on the waste chips is separated from the waste chips under the centrifugal force, meanwhile, the cooling liquid at the bottom of the spin-drying drum 12 flies out from the drain hole 19 obliquely upwards from the bottom under the action of the centrifugal force, then the cooling liquid in the spin-drying drum 12 flies out from the drain hole 19 with tiny waste chips, and hits the inner side wall of the outer sleeve 9, and the cooling liquid always falls above the sponge block 10;
finally, the cooling liquid falling on the outer sleeve 9 gradually falls and is absorbed by the sponge block 10, at the moment, the rotating gravity ball 24 continuously extrudes the sponge block 10 to ensure that the cooling liquid absorbed in the sponge block 10 is extruded, the cooling liquid continuously moves downwards and is continuously absorbed by the sponge block 10 positioned below until reaching the sponge block 10 positioned below, after the sponge block 10 positioned below is extruded, the cooling liquid falls to the bottom of the outer sleeve 9 and finally is discharged from the liquid outlet 901 through the liquid discharge pipe 401, in the process, fine waste scraps are filtered by the sponge block 10, meanwhile, when the gravity ball 24 extrudes the sponge block 10, the thickness of the sponge block 10 ensures that the gravity ball 24 is stressed to move towards the center direction of the spin-drying drum 12, the movable rod 21 synchronously moves towards the center direction of the spin-drying drum 12, and under the action of centrifugal force, after leaving the sponge block 10, the cooling liquid moves towards the direction away from the center of the spin-drying drum 12 again, the movable rod 21 is made to reciprocate, the movable rod 21 is made to push the scraps nearby the movable rod 21 to enable the scraps to be stressed and continuously bulge, meanwhile, the gap between the scraps is continuously changed, cooling liquid can be rapidly discharged through the liquid discharge hole 19, then after the spin-drying is completed (the specific spin-drying time can be set), the numerical control program is used for controlling the rotating motor 16 to stop rotating, the spin-drying drum 12 is stopped rotating, meanwhile, the numerical control program is used for controlling the hydraulic assembly 14, the valve 15 is controlled to move downwards to open the interface between the spin-drying drum 12 and the slag discharge pipe 13, at the moment, the scraps in the spin-drying drum 12 lose centrifugal force, meanwhile, the reset spring 25 drives the gravity ball 24 and the movable rod 21 to reset and move towards the center direction of the spin-drying drum 12, at the moment, the space of the liquid storage cavity I201 is continuously reduced, the space of the liquid storage cavity II is continuously enlarged, and the liquid in the liquid storage cavity I201 is extruded by the partition plate 22, the liquid level gradually exceeds the height of the through hole 23, the movable rod 21 is gradually extruded into the liquid storage cavity II 202 through the through hole, the movable rod 21 is slowly moved towards the center of the spin-drying drum 12, the movable rod 21 continuously pushes surrounding scraps, the scraps are discharged into the slag discharging pipe 13 under the dead weight and the pushing action of the movable rod 21 and finally fall into the collecting disc 3 below, when the movable rod 21 is completely reset, the number of the scraps remained on the movable rod 21 is small, a filter layer cannot be formed again, then the numerical control program controls the hydraulic assembly 14, the valve 15 is driven to close the interface between the spin-drying drum 12 and the slag discharging pipe 13 again, then the numerical control program controls the reciprocating mechanism assembly 5, the valve plate I7 is driven to open the right side liquid inlet pipe 11 again, the valve plate II 8 is driven to close the left side liquid inlet pipe 11 again, the spin-drying drum 12 on the left side is driven to repeat the spin-drying action, the cooling liquid mixed with the scraps falls into the opened liquid inlet pipe 11 again, the above action is repeated, the separation of the scraps and the cooling liquid is finished, after the processing is finished, the outer sleeve pipe 10 is removed, and the sponge 10 can be cleaned.
