Continuous centrifugal dewatering device

A continuous centrifugal dewatering device comprising:

• an external case having an internal space;
• a feed supply pipe to which a slurry as a mixture of a solid and a first liquid is supplied;
• a basket provided inside the external case, configured to receive a first gas and the slurry provided thereto and rotate to apply centrifugal force to the slurry;
• a plurality of holes formed in the basket and configured to discharge a second liquid filtered from the slurry to an outside of the basket;
• a pusher plate provided inside the basket and configured to discharge a slurry cake attached to an inner circumferential surface of the basket to an outside of the external case;
• a non-contact seal configured to prevent the first gas from flowing into a space between the external case and the basket;
• and
• a gas inlet to which a second gas, which flows in a reverse direction with respect to a flow direction of the first gas flowing to the space between the external case and the basket, is continuously supplied,
• wherein the first gas is discharged externally from the basket through the plurality of holes formed in the basket,
• wherein basket has a cylindrical shape, and the gas inlet is provided in a form of one or more pores formed along a circumference of the basket, and
• wherein the gas inlet is positioned between the plurality of holes and the non-contact seal.
