[0048] Then the first gear 607, the second gear 608 and the third gear 611 are driven to engage and drive by starting the servo motor 606, the second gear 608 is fixedly connected to the top of the first rotating shaft 609, the third gear 611 is fixedly connected to the top of the second rotating shaft 610, and the first rotating shaft 609 is movably sleeved in the inside of the second rotating shaft 610, so that the rotating directions of the first rotating shaft 609 and the second rotating shaft 610 are opposite, and the first fan blade 612 and the second fan blade 613 are further driven to approach or move away at the same time, when the first fan blade 612 and the second fan blade 613 approach, the sludge between the first fan blade 612 and the second fan blade 613 is extruded, and the water in the sludge is filtered out through the screen 614, at this time, the water is discharged by opening the drain pipe 5.

[0049] Finally, when the water is discharged, the first rotating disc 615 is driven to rotate by manually rotating the handle 617, until the holes opened in the first rotating disc 615 and the second rotating disc 616 are coincided, at this time, the extruded sludge falls into the funnel 2 through the holes in the first rotating disc 615 and the second rotating disc 616, and finally is taken away for heavy metal treatment by the transmission belt.
