PCT No. PCT/SE96/00169 Sec. 371 Date Nov. 10, 1997 Sec. 102(e) Date Nov. 10, 1997 PCT Filed Feb. 12, 1996 PCT Pub. No. WO96/25234 PCT Pub. Date Aug. 22, 1996Inlet device for a centrifugal separator, which easily can be modified so that the centrifugal separator in a simple way can get a broadened range of applications. To obtain this an inlet device according to the invention is composed by a first part (11), which forms a first portion (15) of the inlet channel with an inlet (16) and an outlet (17), located radially outside this, and a second part (12), which is formed by a frusto conical flowing disc and is arranged between the outlet (17) of the first portion (15) of the inlet channel and a stack of separation discs (24) in a separation chamber (6), towards which a second part (12) delimits at least one second portion (18) of the inlet channel, which is connected to the outlet (17) of the first portion (15) of the inlet channel and opens in at least one opening (19) arranged in the flowing disc, which is located at a radial distance from the outlet of the first portion (15) of the inlet channel, and the second portion (18) of the inlet channel having a zone (20) surrounding the rotation axis, which is located radially between the outlet (17) of the first portion (15) of the inlet channel and the at least one opening (19), and essentially is out of obstacles for liquid to flow in circumferential direction relative to the inlet device. |
