Description

Technical Field

[0001] The utility model relates to the technical field of dehydration devices, in particular to a dehydration device for mixed slurry. Background Art

[0002] The dehydration device mainly consists of a transfer device and a screw conveyor with a hollow rotating shaft. The sludge is fed into the hollow rotating shaft and then into the rotating drum. Under the action of the centrifugal force generated by high-speed rotation, it is immediately thrown into the hub cavity. The sludge particles have a relatively large specific gravity, so the centrifugal force generated is also large, and they are thrown and adhered to the inner wall of the hub to form a solid layer; water has a small density and a small centrifugal force, and only a liquid layer is generated inside the solid layer. The sludge in the solid layer is slowly pushed by the screw conveyor to the tapered end of the transfer device and continuously discharged through the outlet around the transfer device, while the liquid overflows from the weir to the outside of the transfer device and is discharged after collection.

[0003] During the dehydration process of the existing dehydration device, high-speed rotation is required, resulting in relatively high noise. After the mixed slurry is dehydrated, two servo motors are required for screw feeding, resulting in too high a cost for dehydrating the mixed slurry. Therefore, the energy consumption cost is too high when the dehydration device dehydrates the slurry. Summary of the Utility Model
