Described impeller adopts the impeller that is no more than 4 blades; Described screw mandrel adopts ball screw, in order to reduce wearing and tearing; In order to guarantee the seal of sand setting case, sand setting casing both sides solid phase outlet is designed to two sections symmetry half arcs, its radian is between 90 °-100 °, and four blades that are mutually the right angle that make the discharging rotating disk like this can make the sand setting case keep airtight in rotary course all the time; Described screen frame is connected to form by four root plates, screen cloth and middle nut; The all outer motor drives that connects that rotatablely moves of impeller, screw mandrel and discharging rotating disk.

The utility model is compared with traditional Separation of Solid and Liquid cyclone device and is had the following advantages:

1, the utility model can solve existing cyclone device stops up the equipment that influences because of underflow pipe in application process operate as normal; Eliminate the harmful effect of air column, help further to improve the Separation of Solid and Liquid efficiency of hydrocyclone Separation of Solid and Liquid cyclone separative efficiency.2, the utlity model has the underflow thickening function, the underflow of having avoided causing owing to Separation of Solid and Liquid cyclone underflow solid concentration is low is wasted and the underflow after-treatment, and this lays the first stone for promoting the use of of cyclone.
