Description

The invention relates to devices for hydromechanical processes of separation of disperse systems in the field of centrifugal and gravitational forces and can be used in the chemical, mining, metallurgical industry and several other sectors of the economy.

The purpose of the invention is to increase the productivity of the apparatus and separation efficiency.

The drawing shows a turbocyclone, a general view.

The turbocyclone contains a housing 1, in the upper part of which a turbine Ϊ is installed, made in the form of a set of cylindrical shells 3. interconnected by kerchiefs 4 and ribs 5 with a shaft 6 arranged concentrically, with a gap in one another, with each inner shell located below the upper edge outer shell. In the lower part of the housing 1 A pipe 7. is installed. It is connected to the erythrite 8 of unloading the heavy fraction and axially, with the possibility of axial movement of the pipe 9, connected by a flexible sleeve 10 to the airlift 11 of unloading the Industrial product. At the top of the housing 1. I am glad that the turbine 2 has a receiving box 12 with a supply pipe 13. a drain pipe 14 and a groove 15 for unloading a light fraction. On the shaft 6, located inside the pipe 14, above the groove 15 there is a bearing assembly 16 and an opener 17. The upper shoes of the airlifts 8 and 11 are equipped with receiving boxes 18 with locking devices 19. The air in the airlifts is fed through nozzles 20. Reception • Naya box 12 with power supply the pipe 13 'is a source material loading device. The drain pipe 14 with the Gutter 15 and the chipper 17 form a light fraction discharge device. The pipe 7 and axially mounted with the possibility of axial movement of the pipe 9 form a device for unloading a heavy fraction and industrial product, respectively.

Turbocyclone works as follows.

The pipe 13 in the receiving cylindrical box 12 is fed with the source material - ore fines and suspension. Under the action of centrifugal forces arising from the rotation of the turbine 2, denser and larger pieces of the enriched material (heavy product) are directed to the periphery, to the inner wall of the shell 3 of the turbine 2, rotating at the same angular speed as the working medium. Then, under the action of gravity, the heavy product is lowered along the wall of the shell 3 into the annular gap formed by the lower shell of a smaller diameter when it is covered by the upper shell. The kerchiefs 4 provide rigidity to the design of the turbine 2, and the ribs B transmit it the torque from the shaft 6. On the wall of the housing 1, the heavy product moves down to the pipe 7 for unloading the heavy fraction and airlift 8 is fed into the box 18. The outer walls of the shells 3 of the turbine 2 prevent mixing of the allocated heavy product with undivided material.

A light fraction of the starting material is directed through the drain pipe 14 into the trough 15.

The height-adjustable pipe 9 is connected by a flexible sleeve 10 to the airlift 11 and serves to unload the intermediate product of the required purity into the receiving box 18. Locking devices of the plug type 19 serve for sparging when turbo-cyclone stops.

If it is necessary to separate the material into two products, the mid-air airlift 11 can be turned off. Through nozzles 20, air is connected to the airlifts. Existence of the unloading regulated by airlift allows to regulate the process in a wide range.

The bearing assembly 16 is protected against splashing of the suspension of the chippers 17.

Thus, the implementation of the turbine 2 in the form of a set of cylindrical shells 3, interconnected by scarves 4 and ribs 5 with a shaft 6, arranged concentrically, with a gap in one another, so that each inner shell is located below the upper edge of the outer shell allows you to increase productivity apparatus by increasing the working volume of the separation zone of the material, to exclude the possibility of contact ^: tation in the separation zone (at the top of the turbocyclone) of a heavy product with a fixed wall of the casing at, thereby preventing its wear, and allows the process to be carried out sequentially in smaller hydrocyclones with continuous removal of the heavy fraction, eliminating the possibility of mixing it with the intermediate, which increases the efficiency of the separation process.
