The original slurry through the feed nozzle 2 enters K1 and twists. Under the action of centrifugal forces, large particles of the solid phase are thrown against the walls of K1, and the thinnest class is concentrated in the center in the axial zone. The latter is discharged through the corresponding RP N and the gap 9 between the upper and middle C 6, on which the diffuser 7 and the diffuser 8 are installed, respectively. Similarly, the product of a different size is discharged through the gap between the middle and lower C6. The coarse-grained portion is concentrated at the walls of K1 and discharged through RP 11, located at the base of K1. The specified grain size of the boundary grains in the classification products and the redistribution of the fluxes are achieved by moving the middle cylinder of the Ts6 cascade vertically by means of the rod 5 and the adjustment mechanism 4. 1 sludge,

The invention relates to a device for separating suspensions, classifying materials by size, and can be used in the chemical, mining, coal and other industries.

The purpose of the invention is to increase the efficiency of classification.

The drawing shows a hydrocassificator, general view, section.

The hydroclassifier consists of a cylindrical body 1, a tangential supply nozzle 2, a cover 3, an adjustment mechanism 4 connected via a rod 5 to the middle cylinder of a cascade of cylinders 6, each of which is coupled along the bottom edge to the diffusers 7 and over the confusers 8, gaps 9 for, assignment of selected size classes, bottom 10 and discharge devices 11.

Hydroclassifier works in the following way.

Through the tangential supply nozzle 2, the pulp enters the cylindrical body 1 of the hydroclassifier, having a cover 3 and a bottom 10. When the pulp moves in the center in the axial zone, the thinnest part of the pulp is discharged, which is discharged through the gap 9 between the upper and middle cylinders to the discharge part The device 11. The gap 9 is formed by the mating of the lower edge of the cylinder

6 with a diffuser 7 and the upper edge of the subsequent cylinder with confuser 8

Similarly, through the gap between the middle and: lower 1; the next class is allocated and removed.

The coarse-grained portion is concentrated at the outer walls at the bottom of the casing and is discharged through a discharge device 11 located at the base of the cylindrical casing 1.

At the level of the supply of gulbulpa, the volume of the hydroclassifier is greatest, since the diameters of the cylinders increase from top to bottom, which creates favorable conditions for the classification and separation of the fine-grained part of the pulp.

The specified separation grain size is achieved by moving the middle cylinder of the cascade of cylinders 6 vertically thanks to a rod 5 with an adjustment mechanism 4.

The application of the proposed hydroclassifier in the practice of mineral processing No. 1x will make it possible to isolate a number of size classes, which, depending on their liberty, can be used for enrichment by flotation, for dewatering into centrifuges and vacuum filters, and dump
