The invention relates to the field of separation of heterogeneous media, in particular to the separation of bulk materials in hydrocyclones, and can be used for enrichment. materials in the coal, mining, metallurgical and other industries of the industry.

Known three-product cascade hydrocyclone with free-flow loading, containing a cylindrical and cylindrical sections, interconnected by a transition pipe, inlet and outlet, pipes 1.,

The disadvantage of this hydro-cyclone is its complexity, consisting in joining two separate shells. In addition, the separation of the suspension for the second section is carried out together with the starting material, the particles of which (especially large ones) interfere with the good separation of the suspensions created around the vortices.

It is also known a device for separating mixtures of solid materials, comprising a cylindrical body, a dividing partition with a transition nozzle, dividing the body into the upper and lower chambers, the axial tube dp of the raw material supply, the tangential nozzle for the suspension, and the nozzle for unloading the separation products 2.

The disadvantages of the known device are its low separation efficiency due to the loss of combustible mass with waste and the complexity of the complex as a whole due to the presence of two slurry collectors, two working pumps, two piping systems and recycling. This requires additional staff and large production areas.

The purpose of the invention is to improve the efficiency of separation and simplification of a hydrocyclone separation complex.

The goal is achieved by the fact that three products B1 hydrocyclone with free-flow loading of the source material containing a cylindrical housing, a dividing partition with a transitional pipe, an axial pipe for feeding the source material, a tangium pipe for unloading products in section 567412

No, it is provided with an additional partition made with annular cuts near the wall of the case and reinforced on the transition pipe of the top 5 of the separation wall, while the separation wall is made with ring cuts at the transition pipe.

FIG. 1 shows a three-product hydrocyclone, general view; FIG. 2 is a section A-A in FIG. P, in FIG. 3 is a section BB in FIG. 1. A hydrocyclone consists of a housing 1 with an axial nozzle 2 for loading the raw material, a tangential nozzle 3 for feeding the suspension into a cyclone, and nozzles A and 5 for unloading obtained in a cyclone of light and intermediate products.

0 The hydrocyclone inside is partitioned off by partitions 6 and 7 into the lower and upper enrichment chambers 8 and 9 and the sticking chamber 10 for separating the working suspension into a thickened and clarified suspension. Through partitions 6 and 7, the transition nozzle 11 passes coaxially with the cyclone. The intermediate chamber 10 is connected to the upper processing chamber 9.

Q by the annular annular channel 13 formed by the extrusions (Fig. 2) in the partition 7, the lower beneficiation chamber 8 - by the annular channel around the transitional pipe 11, formed by the notches 14 (Fig. 3) in the partition 6.

The hydraulic pitch works as follows.

0 The working suspension is fed through a tangential nozzle 3 under pressure to the chamber 10, where under the action of centrifugal force it stratifies in density: more dense (thickened)

5, the slurry layer, pressed against the wall, passes through the annular annular channel 13, formed by the UL cutout, into the upper processing chamber 9, and the less dense clarified.

The 0 layer goes through the channel around the axial nozzle 11 formed by the notches 14 into the lower chamber 8. The raw material enters the axial nozzle 2 into the upper processing chamber 5, where the crynie suspension slurry into this chamber through the hollow channel 13 is unwound.
