Document Type and Number:
Japanese Patent JP6706692
Kind Code:
B2
Abstract:
A rotary joint (5) of a centrifugal separator (1) is provided with: a shaft body (20) which is immovably installed; and a cylinder body (21) which is rotated. The rotary joint includes: a shaft-side supply flow path (30) and a shaft-side discharge flow path (31) which are provided inside the shaft body; a cylinder-side supply flow path (32) and a cylinder-side discharge flow path (33) which are provided passing through the cylinder body (21) from the inner circumferential surface to the outer circumferential surface of the cylinder body (21); and a supply communication flow path (34) and a discharge communication flow path (35) which are annular, and which are provided between the outer circumferential surface of the shaft body (20) and the inner circumferential surface of the cylinder body (21). The cylinder-side supply flow path (32) is inclined in the opposite direction to the rotation direction of the cylinder body (21), with respect to a radial direction (R1) which extends from the shaft body (20) through a part (32b) connecting the cylinder-side supply flow path (32) and the supply communication flow path (34). The cylinder-side discharge flow path (33) is inclined in the same direction as the rotation direction of the cylinder body (21), with respect to a radial direction (R2) which extends from the shaft body (20) through a part (33b) connecting the cylinder-side discharge flow path (33) and the discharge communication flow path (35).
