The centrifugal throwing disc rotating together with the centrifugal lifting main shaft further performs efficient centrifugal operation on the sludge, enabling the sludge to undergo another dewatering process during the process of being thrown towards the inner spherical shell.

Subsequently, this water will be pumped out by the set pumping component and discharged outside the treatment chamber to ensure the effective removal of water.

[0018] After one cycle is completed, the preliminarily dewatered sludge will fall back onto the water-permeable plate again to continue the above dewatering steps. This cyclic process greatly improves the dewatering effect of the sludge and achieves efficient water separation.

This not only helps to meet the extraction requirements of sludge layers with different thicknesses but also further optimizes the stratified treatment effect of the sludge and improves the overall treatment efficiency. Finally, the fully dewatered sludge can be discharged orderly under the control of the discharging mechanism, ensuring the stability and consistency of the treatment results.

A spiral feeding blade 46 is fixedly installed on the centrifugal lifting main shaft 37 inside the lifting cylinder 36. A centrifugal throwing disc 47 is rotatably installed at the upper end of the lifting cylinder 36, and the centrifugal throwing disc 47 is also fixedly connected to the centrifugal lifting main shaft 37 through a second diagonal strut 44; The centrifugal dehydration mechanism 21 further includes a water pumping assembly installed on the fixed platform 30 for pumping the water in the water accumulation cavity 45 between the outer spherical shell 33 and the inner spherical shell 42 to the outside of the treatment bin 7; A water seepage plate 22 is fixedly installed at the lower part inside the treatment bin 7, and the discharging mechanism is used to control the discharge of the sludge above the water seepage plate 22; A lifting mechanism is fixedly installed at the top of the treatment bin 7, and the lifting mechanism is connected to the centrifugal dehydration mechanism 21 and used to drive its lifting.

[0026] In the embodiment of the present invention, during the sludge treatment process, the sludge to be treated is added into the treatment bin 7 through the feeding port 9.

This not only helps to meet the extraction requirements of sludge layers with different thicknesses, but also further optimizes the layered treatment effect of the sludge and improves the overall treatment efficiency. Finally, the fully dehydrated sludge can be discharged orderly under the control of the discharging mechanism, ensuring the stability and consistency of the treatment results.

The spiral feeding blade 46 conveys the sludge upward to the centrifugal throwing disc 47.

After the driving assembly is started, the centrifugal lifting main shaft 37 and the transmission pipe 43 rotate in opposite directions, driving the spiral feeding blades 46 and the centrifugal disc 47 to rotate at high speed, conveying the sludge on the water permeable plate 22 upward and throwing it onto the mesh wall surface of the inner spherical shell 42, enabling the sludge to further undergo centrifugal dehydration. The separated water enters the water accumulation chamber 45 and is discharged through the pumping assembly. The dehydrated sludge falls back onto the water permeable plate 22 from the lower end of the outer spherical shell 33, forming a circulating treatment path and continuously improving the dehydration effect. At the same time, the lifting mechanism can adjust the height of the centrifugal dehydration mechanism 21 to achieve precise extraction of sludge at different levels; the material disturbance pipe 24 cooperates with the air flow nozzle 23 to turn over and aerate and dry the sludge, enhancing the mixing and dehydration efficiency; the pressure regulating and dehydration assembly creates a positive and negative pressure difference above and below the water permeable plate 22, significantly improving the dehydration speed and efficiency; the finally treated sludge is orderly discharged through the discharging mechanism and output by the material transfer belt 10.
