    • The invention relates to an apparatus (1, 1a, 1b) for separating particles in a pulp suspension, which apparatus (1, 1a, 1b) comprises a housing (14), a barrier (2, 2a, 2b) with apertures, an inlet (3, 3a, 3b) for the pulp suspension, a first outlet (4, 4a, 4b) for material with large particles not having passed the barrier (2, 2a, 2b), a second outlet (5, 5a, 5b) for material with small particles having passed the barrier (2, 2a, 2b), and a rotor (6) on an axis (9), which rotor (6) is arranged to create a fluidization zone (8, 8a, 8b) near the barrier (2, 2a, 2b). According to the invention the apparatus (1, 1a, 1b) comprises a separation chamber (7, 7a, 7b) having a toroid shape. The rotor (6) is arranged to both create a circular flow of the incoming pulp suspension in the separation chamber (7, 7a, 7b) and to clean the barrier (2, 2a, 2b) from the pulp suspension.
    • 本发明涉及一种用于分离纸浆悬浮液中的颗粒的装置(1,1a,1b),该装置(1,1a,1b)包括壳体(14),具有孔的屏障(2,2a,2b), 用于纸浆悬浮液的入口(3,3a,3b),用于具有未通过阻挡层(2,2a,2b)的大颗粒的材料的第一出口(4,4a,4b),第二出口(5,5a,5b) ),具有通过阻挡层(2,2a,2b)的小颗粒的材料和轴(9)上的转子(6),该转子(6)被布置成产生流化区(8,8a,8b) 靠近屏障(2,2a,2b)。 根据本发明,装置(1,1a,1b)包括具有环形形状的分离室(7,7a,7b)。 转子(6)布置成在分离室(7,7a,7b)中产生进入的纸浆悬浮液的圆形流,并从纸浆悬浮液清洁阻挡层(2,2a,2b)。
