[0029] When the rotation of the throwing box 45 is controlled, the first power member 442 is started, the first power member 442 is a motor, the output shaft of the first power member 442 drives the driving gear 443 to rotate, the driving gear 443 drives the driven gear 445 and the rotating column 444 to rotate, the rotation of the rotating column 444 drives the throwing box 45 connected thereto to rotate, the rotation of the rotating column 444 can also drive the second bevel gear 446 to rotate, the rotation of the second bevel gear 446 drives the stirring assembly 38 to stir and mix the wastewater and the precipitant, the rotation of the second bevel gear 446 can also drive the third bevel gear 448 to rotate, the third bevel gear 448 drives the shaft rod 447 to rotate, so as to drive the stirring rod 449 to stir the wastewater at the filter plate 42, thereby avoiding that the small solid impurities are deposited on the filter plate 42.

To remove the large solid impurities, the second power component 71 is activated. The second power component 71 is a motor. The output shaft of the second power component 71 drives the fourth bevel gear 72 to rotate, which in turn drives the fifth bevel gear 75, the synchronizing rod 74, and the lead screw 73 to rotate. The rotation of the lead screw 73 causes the two moving blocks 76 and the guide wheel 710 to move away from each other along the guide groove 79.
