Abstract
The utility model relates to an eddy separation device, concretely an efficient swirler for concentrating and grading a gypsum slurry concentrated fractionation, characterized in that: a vertical column segment is arranged below a shell and a first-level cone barrel is arranged below the vertical column segment and a second-level cone barrel is arranged below the first-level cone barrel and a third-level cone barrel is arranged below the second-level cone barrel and a bottom flow tube is arranged below the third-level cone barrel. The efficient swirler increases the separation space in the swirler, increases the staying time of the fluid in the swirler and the separation accuracy and fractionation efficiency; effectively increases the fluid throughput when increasing the separation space. In the multi-level cone barrel structure, the first-level cone is a large cone barrel and the tangential velocity of the fluid is effectively increased and the centrifugal force is increased, therefore the fractionation concentration efficiency is increased; the second-level cone barrel is a small cone barrel and the third-level cone provides a space for secondary fine separation and the bottom flow port is a long cone structure. On one hand, the structure increases the radial speed of the fluid and more fine particle and fluid enter into the swirler to eddy and be discharged from the overflow, therefore the bottom flow concentration is increased and the concentration performance is increased; on another hand, the diameter of the air column is reduced, the fluctuation of the air column is stabilized to be favorable for fractionation and concentration.
