The invention relates to a technique for the separation of inhomogeneous liquid media in a centrifugal field and can be used in geology, oil and gas, as well as in the chemical and food industries.

The purpose of the invention is to increase efficiency.

The drawing shows a hydrocyclone, a general view.

The hydrocyclone includes a housing 1 with a cylindrical 2 and a conical 3 parts, a tangential inlet 4 in the cylindrical part 2, a drain nozzle 5 installed coaxially with the housing 1, a drain channel 6 and a sand nozzle 7. The axis of the housing has a rod 8 with a local cone-shaped thickening 9, placed in a variable-section chamber 10, with a piston 11 equipped with a seal 12, and a head 13. Coaxially to the rod 8 with a gap relative to it, there is a sleeve 14 mounted with the possibility of axial movement using a threaded connector and equipped with a steering wheel 15. The rod 8 is spring-loaded two

springs, one of which (16) is installed between the piston 11 and the sleeve 14, and the other (17) between the sleeve 14 and the head 13. The body has a pointer 18 for positioning the rod with a gap relative to the handwheel 15.

The pulp containing solid particles is fed under pressure into the body 1 through the tangential inlet 4, acquires a rotational movement, which ensures

division of material into thin and coarse products. A thin product is removed by a hydrocyclone through the drain pipe 5 and the drain channel 6, and coarse through a sand nozzle 7. Rotating the hand wheel 15 sets the rod 8 with such a gap between it and the sand nozzle 7, which determines the required degree of classification and thickening of the solid product.

When driving the hole of the sand nozzle 7 in the sub-piston cavity, the pressure increases. The rod 8 with a local cone-shaped thickening 9 moves upwards, increasing the gap between the sand nozzle 7 and the rod 8 and reducing the flow area in the chamber 10 of variable section. At the same time, the flow of fluid to the drain decreases, in the gap between the sand nozzle 7 and the rod 8 it increases and the sand nozzle 7 is cleaned. After the pressure in the housing stabilizes, the spring-loaded piston 11 returns the rod to its original position. The device operates automatically. It is possible to eliminate the clogging of the opening of the sand nozzle 7 by mechanically reciprocating the rod 8 by exposing it to the head 13. After the clogging is eliminated, the rod 8 is self-adjusting to the predetermined position by the action of springs 16 and 7.

The presence of the rod position indicator 18 makes it possible to set a certain size of the gap between the sand nozzle 7 and the rod 8, which

The ra is automatically maintained during operation.

The use of the device allows improving the quality of pulp cleaning, the effectiveness of thickening and removing solid product, as well as reducing the cost of overcoming complications due to clogging of sand packing.
