[0043] After the water and reagent have fully dissolved in the mixture, the second filter screen 7 is initially tilted. The third servo motor 29 drives the control box 23 and the first shaft 5 to rotate via the third rotating shaft 26, causing the first shaft 5 to rotate above the control box 23. The stirring blade 6 is no longer in the mixture. The lifting frame 34 is then moved upwards via the third hydraulic telescopic rod 35. The lifting frame 34 pushes the second translation seat 32 and the second filter screen 7 upwards synchronously via the fourth rotating shaft 39 and the connecting plate 38.

The design enhances the sealing of the connections between the fourth rotating shaft 39 and the movable rod 45 and the processing box 1.

The fifth hydraulic telescopic rod 46 drives the movable rod 45 and the iron plate 47 to move upwards.
