PURPOSE: A centrifugal separation type sludge dehydrator is provided to enable continuous operation and improve dehydration efficiency and workability by installing a screw in a centrifugal separator so that sludge dehydrated by centrifugal separation is automatically discharged out, and water is separately discharged. CONSTITUTION: The centrifugal separation type sludge dehydrator comprises a centrifugal separator(1) at one side of which a sludge outlet(10) is formed, and at the other side of which a drainage(11) is formed; a shaft(2) which penetrates the center of the centrifugal separator(1) and is constructed of a double layer of inner and outer cylinder bodies(20,21), a plurality of sludge discharge ports(22) are formed on the outer circumferential surface of the inner and outer cylinder bodies(20,21), and a sludge injection port(23) is formed at one side of the inner cylinder body(20); a rotation cylinder body(3) which is rotated by the shaft(2) of the inner cylinder body(20), at one side of which a dehydrated sludge dropping port(30) is formed, and on the outer circumferential surface of which a filter(31) is formed; and a screw(210) which is rotationally coupled to the outer circumferential surface of the shaft(2) of the outer cylinder body(21), wherein the filter(31) comprises a multiple net from the inside of which an inner stainless steel filter(310), a stainless steel mesh filter(320) and an outer stainless steel filter(330) are formed; supports that are formed on the stainless steel mesh filter(320) with the supports separated apart from each other in a certain distance; and a holder capable of holding the stainless steel mesh filter(320).
