[0031] When the blade 207 is located in the middle of the cylinder 203, the servo motor 201 is then rotated counterclockwise, the centrifugal force received by the polycarboxylate dispersant solid at the bottom is reduced, so that the polycarboxylate dispersant solid at the bottom does not rotate fast along the inner wall of the cylinder 203, then the sieve plate 206 is triggered to slide along the two fixed rods 204 through the two movable blocks 205, the sieve plate 206 leaves a space for movement between the sieve plate 206 and the inner wall of the crushing tank 101, the sieve plate 206 reciprocates in the horizontal direction, so as to quickly sieve the crushed polycarboxylate dispersant solid to improve the sieving efficiency, then the blade 207 is lowered to the bottom again by the electric telescopic rod 104, and the servo motor 201 is rotated clockwise to quickly crush the polycarboxylate dispersant solid, thereby circulating to ensure that the polycarboxylate dispersant solid can be quickly crushed and sieved.
