When the water and the medicine are fully dissolved in a single batch, the second filter screen 7 is initially in a tilted state, and the third servo motor 29 drives the control box 23 and the first shaft 5 to rotate through the third shaft 26, so that the first shaft 5 rotates to the top of the control box 23, and the stirring blade 6 is no longer located in the mixed liquid. The lifting frame 34 is driven to move upward by the third hydraulic telescopic rod 35, and the lifting frame 34 pushes the second translation seat 32 and the second filter screen 7 to move upward synchronously through the fourth shaft 39 and the connecting plate 38.

As the second filter screen 7 moves downward, the impurities in the mixed liquid are filtered through the two second filter screens 7. Finally, the second filter screen 7 moves to the bottom of the water outlet pipe 50, and the treated water can be discharged through the water outlet pipe 50. The impurities remain under the second filter screen 7. When the mixing process is carried out next time, the third servo motor 29 drives the third rotating shaft 26 and the control box 23 to rotate, so that the first rotating shaft 5 can be rotated again to between the control box 23 and the second filter screen 7. When the stirring is completed, the third servo motor 29 drives the first rotating shaft 5 to rotate to the top of the control box 23 through the third rotating shaft 26 again, and drives the slide plate 41 through the fourth hydraulic telescopic rod 44. The guide block 37 drives the second translation seat 32 to move in the opposite horizontal direction, and the fifth hydraulic telescopic rod 46 drives the movable rod 45 and the iron plate 47 to move upward. The iron plate 47 drags the lifting seat 30 upward through the magnet block 48 to ensure that the second filter screen 7 is in a tilted state again. When the iron plate 47 moves to a preset height relative to the lifting frame 34, the movable rod 45 and the iron plate 47 are driven downward by the fifth hydraulic telescopic rod 46 so that the iron plate 47 is no longer in contact with the magnet block 48. The iron plate 47 is reset to its initial position relative to the lifting frame 34. When the second filter screen 7 is tilted to a preset angle, the above operation steps are repeated to move the second filter screen 7 above the mixed liquid, and the second filter screen 7 again filters impurities in the water to the bottom of the outlet pipe 50.When there are a lot of impurities below the water outlet pipe 50, open the valve on the impurity outlet pipe 31 and the staff will add water to the treatment box 1. The water flow will carry the impurities in the treatment box 1 and discharge them through the impurity outlet pipe 31. This can store the impurities in the mixed liquid each time, preventing the impurities from being discharged through the water outlet pipe 50. It can also concentrate the impurities in the mixed liquid and improve the cleaning efficiency.
