Abstract:
PCT No. PCT/SE89/00138 Sec. 371 Date Nov. 1, 1990 Sec. 102(e) Date Nov. 1, 1990 PCT Filed Apr. 16, 1989 PCT Pub. No. WO89/10793 PCT Pub. Date Nov. 16, 1989.In a centrifugal separator there is formed within the rotor a separating chamber (7) and a central chamber (26), which latter communicates with a peripheral part of the separating chamber through a channel (19a, 19b). The part (19a) of the channel situated closest to the central chamber (26) extends substantially parallel with the rotor axis, whereas the other channel part (19b) forms an angle with the rotor axis. For avoiding that solids entrained by liquid entering the channel (19a, 19b) from the separating chamber (7) are separated and depositing on the outer wall of the inner channel part (19a) a partition member (44) is arranged in this inner channel part (19a). The partition member (44) divides the channel part (19a) into two parallel flow ways (45, 46). Further, a pumping means (31) is arranged to pump liquid from the central chamber (26) to one (45) of said flow ways, so that this liquid flows through first said one (45) and then said other (46) flow way and then flows back to the central chamber (26). By the liquid circulation thus established in the inner channel part (19a) the solids are maintained suspended in the liquid until it again leaves the channel part (19a).
