A hydrocyclone consists of a cylinder-conical case 2 with a tangential inlet nozzle 3, a filtrate outlet nozzle 4, sludge (PS) 5 and floating impurities 6, a filter element (F) 7 in the form of a perforated cylinder 8 covered with an elastic microgrid closed 9, having in the lower part an elastic ring 10. The valve (K) 11 is connected by means of a swivel rod 12 to Ф 7 and is held in the lower position by an adjustable spring 13. To the PS 5 to adjust the pressure in the housing is attached a diffuser 14 with a valve 15 and a spring - F 7 under the action the stream makes pendulous vibrations relative to the point of suspension and vibrates in the vertical direction under the action of K 11. 1 sludge.

The invention relates to the technique of separation of inhomogeneous media, specifically to devices for the purification of water from mechanical impurities.

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

The drawing shows a hydro-cyclone, a general view.

A hydrocyclone consists of a closed COVER 1 of a cylindrical housing 2 with a tangential inlet 3) nozzles of the drainage of filtrate 4, psham 5 and floating impurities 6, the filter element 7 is installed in the housing. to the filtrate outlet. The base of the filter element is located in the conical part of the cyclone and has an elastic ring 10. At the outlet of the filtrate drainage pipe, a valve 11 is installed, connected to the filter element by means of a swivel rod 12 and held in the lower position by an adjustable spring 13. 4 with valve 15 and spring

Hydrocyclone works as follows.

The original fluid through a tangential | inlet pipe 3 enters the body 2 and acquires intensive rotational motion. Under the action of centrifugal and gravitational forces, heavy particles of pollution move along the walls of the housing downwards and are removed with a part of the liquid through a pipe 5 of the discharge of the slurry, supporting valve 15 and diffuser 14,

Floating contaminants are concentrated in brick 1 and discharged through pipe 6, Most of the liquid

the filter is filtered through the microcell 9 of the filter element 7 and leaves the hydrocyclone through the nozzle 4 of the filtrate outlet and the valve II,

Filter element by force

the flow loaded in the cyclone and the Venturi effect in the gap between the cyclone body 2 and the bottom of the filter element 7 performs pendulous oscillations with respect to the suspension point.

At the same time, the filter element vibrates in the vertical direction under the action of valve 11, Amplitude, frequency of vertical oscillations and pulsation pressures in the filter element.

regulated by a spring 13,

The pressure in the housing upstream of the filter element 7 is set by adjusting the spring which presses the support valve 15 to the outlet

pipe sludge removal.
