Description

The invention relates to a technique for purifying a liquid, in particular, devices for separating suspensions in a field of centrifugal forces, and can be used in chemical, ore dressing, food and other industries;

The purpose of the invention is to increase the separation ability.

Figure 1 presents the turbo-cyclone, a general view; figure 2 - detail; on fig.Z - section aa in figure 1 (with divorced impeller blades).

The turbo-cyclone consists of a cylindro-conical body 1, a tangential pit nozzle 2, a sand nozzle 3, a drain device 4, made in the form of two coaxial nozzles 5 and 6, installed with the possibility of rotation, each of which is equipped with radial blades 7 and 8, respectively the number of blades of the inner pipe is equal to the number of blades of the outer.

Turbo-cyclone works as follows.

The initial suspension enters the casing 1 of the apparatus through the tangential feed nozzle and is twisted by blades 7 and 8, rotated by the electric

throat drive Under the action of centrifugal forces, the scattering of solid particles is thrown to the walls of the turbo-cyclone and, together with the external downward rotating flow of fluid, moves to the sand nozzle 3, from where it is discharged. The clarified fluid flow forms an internal upward flow and is removed through the discharge device 4. Between the blades 7 and 8, zones of increased turbulence are formed. With an increase in the viscosity of the suspension, for example, with a change in temperature or an increase in the concentration of the suspension, flow turbulization drastically reduces the efficiency of the separation process. In order to eliminate the increased flow turbulization, the nozzles 5 and 6 in the turbo cyclone are installed with the possibility of relative rotation, while rotating, the angle between the blades 7 and 8 changes discretely, for example, from 0 to 45, i.e. the number of blades, the acceleration of kmtsih flow, is doubled. Thus, the application of the proposed design for carrying out suspension separation processes with varying viscosity allows an increase in separation efficiency by reducing flow turbulization.
