Description

The invention relates to a technique for cleaning liquid in a field of centrifugal forces and can be applied in the chemical, food processing, petroleum refining and other industries.

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

The drawing shows a hydrocyclone, a general view.

A hydrocyclone consists of a cylindrical body 1 with a tangential nozzle 2 supplying the initial suspension j of cover 3 with a drain nozzle 4 installed in it and a sand nozzle 5 installed at the apex of the body cone. Adjacent to the lid is a drain chamber 6 with a pipe 7 for draining the purified liquid.

The upper part of the drain chamber is provided with a cover 8, on the inner sides of which a guide cylinder 9 is fixed. A cylindrical filtering chamber 10 is installed in the guide cylinder, the bottom 11 of which is convex toward the drain nozzle 4. The inlet nozzle is installed coaxially above the drain nozzle 12, the diameter of which is smaller than the diameter of the drain nozzle. In the upper part, the cylindrical filter chamber is provided with a cap 13, which is installed in the flanges 14 and is concave inside the filter chamber.

A spindle 15 is installed in the filter chamber cover, passing through the drain chamber cover. The krplk drain chamber under. Screw 15 is executed, but the threaded hole 16. The screw is equipped with a flywheel 17 and is fixed on the roof of the drain chamber with a lock nut 18

Hydrocyclone works as follows.

Source Fluid (Contaminated

water or suspension) through the tangential nozzle 2 enters the cavity of the cylinder-toned body 1, where it receives rotational motion. The solid particles under the action of centrifugal inertial forces fall from the liquid to the wall of the body 1, move to the apex of its conical part in a spiral line and output through the starting pipe 5 to destination. The clarified part of the liquid rises in a rotating stream into the discharge pipe 4, from where part of it flows smoothly through the convex bottom 11 into the cavity of the discharge chamber 6, and a part of the stream containing fibers and lightly sputtering solids that are concentrated along the axis of the apparatus passes through the pipe 12 into the cavity of the cylindrical filter chamber Yu, smoothly directed along the convex surface of the lid 13 to the walls of the chamber 10 and fills its entire volume. On the inner filtering surface of the chamber 10, fibers and lightly erupting solids are retained, and the purified liquid passes through the apertures of the filtering surface of chamber 10 into the cavity of the discharge chamber 6, from where it is discharged through the nozzle 7 from the hydrocyclone. When clogging the filtering surface of chamber 10, the latter is easily removed by washing. To clean heavily contaminated liquids, the filter chamber 10 t using the lead screw 15 opyc caet to such a position that the lower convex part of the bottom 11 blocks the flow of liquid into the cavity of the drain chamber 6 and the entire drain flow is directed to the nozzle 12, and then into the filter cavity chamber 10, while cleaning under pressure of the full flow of the clarified liquid from fibrous and lightly melting solid substances.

As the inlet pressure increases due to the resistance of the layer on the inner filtering surface of the chamber 10, it is periodically washed out.

Depending on the quality of the suspension, the properties of its light solid fraction in this design, the clarification mode is controlled by axial movement of the filtration chamber 10, by mechanical movement of the lead screw 15.
