The invention relates to devices for carrying out hydromechanical processes for the separation of slurries, suspensions, emulsions, and can be used in the food, paint and varnish, microbiological, chemical, petrochemical industry and a number of other sectors of the national economy.

The purpose of the invention is to increase the effectiveness of clarifying the suspension.

FIG. 1 shows a turbo-cyclone, a general view} in FIG. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. A - section BB in FIG. one.

The turbodiclone includes a cylindrical body 1 with a supply nozzle 2, a nozzle 3 for withdrawing the thickened fraction and a nozzle 4 for withdrawing the clarified fraction, which is also a shaft on which the blades 5 of the impeller are fixed, located in the cylindrical part of the housing 1 .. In the conical part coaxially The body is located. A truncated cone 6 with a tube 7 for the outlet of the intermediate product, and with a large base the inner truncated cone is rigidly connected to the pipe 4 with the spokes 8.

Turbo-cyclone works as follows.

The suspension, through the supply nozzle 2, is tangentially under pressure or by gravity fed to the upper part of the housing 1 and the turbines 5 are additionally unwound by rotating blades. Under the action of centrifugal inertial forces, the solid particles move to the walls of the apparatus and along a helical spiral trajectory in the space between the conical part of the housing 1 and the inner truncated cone 6 descend to the lower part of the apparatus, from where this condensed fraction is discharged through the nozzle 3, and rigidly and rotating with —the truncated cone 6 still shrinks the flow in the conical part of the apparatus with the same angular velocity and thus increases the throughput of the turbo-cyclone. In addition, the rotation of the cone prevents the movement of

solid particles and their involvement in the upward flow in the axial zone: the attachment, thereby reducing the entrainment of these particles with the clarified fraction 5 through the outlet nozzle 4.

Particles of a smaller solid suspension that did not reach the near-wall region in the cylindrical

0 parts of the apparatus also move down the} spiral spiral trajectory and fall into the area of the rotating spokes 8. The smallest particles slip between the spokes, and more

5, the coarse ones are dropped by them into the space between the conical part of the housing 1 and the inner truncated cone 6 and are output, together with the condensed fraction.

Small particles trapped in the internal cavity of a rotating truncated cone 6, are separated at large values of the centrifugal forces of inertia due to the smaller geometrical dimensions of the internal cone. The truncated cone 6, rotating with the angular velocity of the nozzle 4, twisting the flow, makes it possible to maintain high values of the tangential velocity along the entire height of the apparatus. Suspension solids discarded against the inner wall of co. nus 6 and down inside

5 of this truncated cone is retracted through the outlet 7 of the intermediate outlet.

Thus, equipping a turbo cyclone with needles that rigidly bind more cone to the cone with the nozzle of the clarified fraction can significantly reduce the amount of solid particles entering the inner cone. In turn, a decrease in the concentration of the solid phase in the inner cone allows a significant increase in the efficiency of clarifying the suspensions. By changing the speed of the Q 4 nozzle (changing the angular velocity of the spokes), you can adjust the number and size of solids that fall into the inner cone, and therefore into the clarified fraction and intermediate product.
