The invention relates to the field of separation of heterogeneous systems and systems G-IST, used in the chemical: and other industries.

The purpose of the invention is to improve the work of TiiHHocTH.

The drawing schematically shows a device, a general view in section.

A device for separating suspensions comprises a housing 1 with a nozzle 2 for outputting a liquid phase, a conical bottom. 3 with a fitting 4 for outputting a solid phase perforated cylindrical shell 5 to the bracket 6. The axis of the cover 6 on the shaft 7 is attached with the possibility of growing a chippeller consisting of two wheels with blades 8 symmetrically spreading less than 1 on each of the toropes of disk 9. ( perforation of the shell 5. The upper part of the inner perforation of the shell is equipped with a pipe 10 to supply the initial suspension and a lid 11 with the center of the aperture 12, which has a flange 13. In the upper part of the inner perforated shell 5 is located mations koptsevoy slit shroud 14 in the form of a truncated cone facing bol- and IR axes Hovhan down.

The device works as follows.

The initial suspension through the nozzle to gets on the outer surface of the shell 14, is directed to the inner surface of the perforated shell 5 and in the ring film B, under the force of gravity, flows down. The air is twisted by a rotating impeach and enters the inside of the perforated shell 5. The downward flow through the inner path: the perforated shell 5 of the initial suspension picks up by the swirling gas flow and also acquires a twisted motion.

Formed during rotation of the impeller, the field of centrifugal forces creates a superfluous excess near the wall of the shell 5.

pressure, 1: one by the action of which the liquid phase is forced through - a perforation cut-in, collects in the lower part of the housing 1 and is discharged through the nozzle 2. The main part of the air passes

together with the fluid through the perforation of the shell 5, moves in an annular space between the perforated shell 5 and the housing 1, through the clamp P with the hole 12 again goes

in the upper part of the impeller and then twisted again.

The separated particles of the solid phase slide down along the walls of the perforated shell 5, fall on the conical bottom 3 and through the fitting 4 are removed from the device.

Formula ji 3 about b ete n i

1, a device for separating suspensions, comprising an internal perforated shell with a nozzle for introducing slurry, placed in a housing with a nozzle for outputting the liquid phase, and an impeller mounted rotatably on the shaft, in order to improve the efficiency, internally perforated. The shell is provided with a lid with a central opening and flange, fixed on the lid with a shell, outlined in the form of a truncated cone, facing a large base located above the impeller. m down, and forming with the side surface of the cover annular gap.

., The device according to claim 1, 10 and 10, so that the impeller is made in the form of a disk with blades symmetrically arranged on both sides.
