    • The invention proposes a device (10) for the cyclonic separation of solid particles contained in a fluid, comprising a primary cyclone chamber (12), a secondary cyclone chamber (14), an inlet channel (90) for fluid loaded with solid particles opening into the primary cyclone chamber, an outlet channel (18) for fluid cleaned of the solid particles connected to the secondary cyclone chamber, and a pipe unit (20) connecting the primary cyclone chamber to the secondary cyclone chamber and surrounded by the primary cyclone chamber. The pipe unit comprises a core (60) delimiting the secondary cyclone chamber and having at least one helical groove of which a bottom moves away from an axis (34) of the secondary cyclone chamber, moving towards the latter, and a cap (62) covering a part of the core in such a way as to delimit, with the groove, a channel (82) connecting the primary cyclone chamber to the secondary cyclone chamber.
    • 本发明提出了一种用于旋流分离流体中所含固体颗粒的装置(10),包括主旋风室(12),次旋风室(14),用于流体加载的固体颗粒开口的入口通道(90) 进入主旋风室;出口通道(18),用于清除连接到次级旋风室的固体颗粒的流体;以及管道单元(20),将主旋风室连接到次级旋风室并由主旋风室 。 管道单元包括限定次旋风室的核心(60),并且具有至少一个螺旋凹槽,底部远离第二旋风室的轴线(34)移动,朝向后者移动;以及帽(62) 覆盖芯部的一部分,使得与凹槽一起限定将主旋风室连接到次旋风室的通道(82)。
