The invention relates to the chemical industry, in particular to rotary apparatuses for carrying out mixing, dispersion, classification, homogenization and extraction processes in liquid-liquid, liquid-gas, liquid-solid, gas-gas, gas-solid systems and gas-liquid-solid, can be used in the construction, food, pharmaceutical, paint and varnish, cosmetic and other industries.

The rotary apparatus consists of a collapsible housing 1,2, equipped with an inlet pipe 3 for supplying a process medium, an output pipe 4 for selecting a finely divided fraction, a pipe 5 for selecting a coarse fraction, and a pipe 6 for introducing technological liquid, solid or gaseous components into the processed medium. An annular chamber 7 and a conical cavity 8 are made in the housing 1,2, in which disks 9 of the rotor 10 of increasing diameter along the flow of the diameter are located with an axial clearance. The different-sized disks 9 are provided with lateral conical surfaces, (lateral bevels 11), expanding along the flow and radial slots 12. The disks 9 are mounted on the drive shaft 13 of the rotor 10 directly or using remote fasteners 14 so that the radial slots 12 were located opposite each other or with offset relative to each other, for example 1/3 of the width of the groove. The drive shaft 13 is provided with a seal 15 and an oiler 16 for forcing lubrication.

The rotary apparatus operates as follows.

The medium to be processed, for example, the suspension is fed into the inlet pipe 3 and distributed along the radial slots 12 between the disks 9 and in the conical cavity 8. The rotor 10 is rotated from the drive shaft 13. Due to friction of the processed medium on the surface of the disks 9 and the Bernoulli effect during the flow of fluid in channels having different passage area (17 - between disks 9; 18

5 - between the lateral bevels 11 of the disks 9 and the surface of the conical cavity 8, 19 - between the surface of the conical cavity 8 and the radial grooves 12 of the disks 9) pressure pulsations from vacuum to excess and centrifugal field arise. In particular, a rarefaction zone arises in the cavity 17 between the disks 9. In the gaps 18 between the side bevels 11 of the disks 9 and the inner surface of the conical cavity 8

5, a rarefaction zone occurs. At halfway between the inner surface of the conical cavity 8 and the walls of the radial slots 12 of the disks 9, a zone arises. high pressure. Because the rotor 10 rotates, and the walls of the internal conical cavity 8 are stationary, traveling waves of compression-compression arise. These waves periodically affect the processed particles of the suspension, creating a pulsating pressure in them with a large amplitude - from positive to discharge. The suspension passing through the disks 9 undergoes mechanical abrasion, shear and impact, disperses. Further it is exposed

0 pulsation processing and hydroacoustic impact (the latter occurs at peripheral rotor speeds of 10 more than 21 m / s) and is discharged into the annular chamber 7. Due to the inertia of the flow and its injection,

5, in the annular chamber 7, the suspension to be treated is twisted into a toroidal vortex. In the center of the vortices, a zone of reduced pressure appears (and for gases and a low temperature), up to discontinuities

0 liquid and cavitational collapse of it, and on the periphery - a zone of high pressure (and for gases and high temperature). Larger and denser particles of the suspension are discarded to the periphery and

5 are taken out by the stream again to the mechanical action zone of the disks 9 for re-dispersing or withdrawn from the annular chamber 7 through the nozzle 5 to the consumer. Small particles are collected in the center of the torus-like vortex, from where they are discharged through

pipe 4 - to the consumer of a finely divided suspension.

If necessary, mix the suspension with other components (reagents), they are introduced through the nozzle 6. The components fall onto the disks 9, are broken by them and scattered. The medium flow picks them up, mixes them and pumps them into the annular chamber 7 - for repeated circulation. Finished products, raw materials and semi-finished products are discharged through the corresponding nozzles 4 and / or 5.

If the rotary apparatus operates on gas-gas or gas-solid media, then lubrication is forcibly supplied to the seal 15 through the lubricator 16.

The technical and economic efficiency of the rotor apparatus lies in its wide functional capabilities. In particular, a rotary mass transfer apparatus can be used to grind suspended particles as they pass through the rotor bodies to a predetermined grain size: mixing substances that are difficult to mix under normal conditions; controlling chemical reactions, for example, by controlled delivery of the smallest impurities; increase in control speed due to a sharp increase in the interface; changes in the shape, structure and condition of substances, for example, due to their melting during circulation in a closed loop

annular chamber: conducting mutually exclusive technological operations in one apparatus, for example, gasification of a liquid by supplying gas through a pipe b and gas degassing by removing gas through a pipe 4, and liquid through a pipe 5; for treating gaseous, liquid and solid media or their various ratios; for treating media contaminated with foreign mechanical impurities, for example, using the apparatus as a cleaning pump; for processing media under high reliability conditions: for in the inventive rotary mass transfer apparatus

there is no stator, screws, and other devices, so the number of possible failures is reduced. The invention is easy to manufacture and reliable.
