Description

the drainage capacity of the apparatus is greatly improved.

FIG. I presents a hydrocyclone, a general view; in fig. 2 - section A-A of FIG. one.

A combined hydrocyclone consists of a cylindrical conical body / with a tangential inlet nozzle 2 and a Peskovy nozzle 3. Inside the outer cylindroconical hydrocyclone, another cylindroconical hydrocyclone 4 is concentrically mounted, the cylindrical part of which is made with longitudinal curvilinear channels 5 with a curvature changing along the flow, communicating with a junction with a junction, and there is a part of the band that is connected with a junction, and there is a part of the flow, and there is a junction with a junction, and there is a junction with a junction, and there is a junction with a junction and a junction with a junction box and a junction box. 6. At the bottom of the drain tube there is a plug 7. The peripheral part of the 1 curved channel is adjacent to the drain at the nozzle, equipped with pockets 8.

The drain nozzle 6, with its conical part 9, communicates with the nozzle W, which discharges the second thickened, finest solid fraction, and the clarified flow is withdrawn through the nozzle 6.

Combined gyrocyclone works as follows.

The initial suspension under pressure flows through the tangential inlet 2 to the cylindrical part of the shell and acquires a rotational motion. Under the action of centrifugal forces, larger particles of the solid phase are thrown to the walls of the hydrocyclone, move down a spiral path and are discharged in the form of a condensed fraction through the sand nozzle 3.

Smaller particles are entrained by the clarified stream, moving upward along the internal spiral, and then smoothly distributed through the channels 5 of the cylindrical part of the internal slope. Solid particles, which still have sufficient inertial force at the entrance to these channels, tend to the peripheral part of these channels and with further movement fall into the pockets adjacent to the drain nozzle 6. The thin solid fraction, falling into the pockets 8, falls into the conical part of the liquid Part 9 of the discharge pipe C is then discharged through the pipe W in the form of a thickened fraction. The clarified stream is discharged through the nozzle 6 with the plug 7.

In this way deep purification of the secondary stream of the clarified fraction is achieved and, as a result, the separation efficiency is increased.
