mechanical impurities, floating bodies and plankton, for example, to ensure the intake of clarified industrial water from the avant-chamber of large pumping stations or from the sewage accumulation basin for its reuse for technical needs or for irrigation.

The purpose of the invention is to increase the filtering capacity of the drain by improving the removal of the floating bodies and plankton from the surface of the drain pipe.

The hydro cyclone is equipped with a Sand pipe 8 and a hydraulic elevator 9 for ejecting sediment, floating bodies and plankton. The tubular casing includes blades 10 and is installed in the supports 11 and 12. A support 14 is attached to the base of the drain nozzle with the aid of a central bolt 13. The drain nozzle 3 is equipped with a drain tool, made in the form of two branches of perforated pipes with slotted slots, one of the branches 15 with slit slots 16 are fixedly mounted inside the drain pipe, and the other branch 17 is installed outside the drain pipe can be rotated about the axis of the housing. The outer branch 17 has a slotted slot 18 directed tangentially to the surface of the mesh.

The hydraulic elevator 9 is equipped with a water supply pipe 5 with a tap 20, and the waste water means is equipped with a common water supply pipe 21 with a crane 22. The outside branch 17 of the waste water equipment is provided with a clutch and lock nut 23 for adjusting the angle of the slotted slot.

It is equipped with tanting slit pads with liquid inlet, and ycTaiioB- bearing equipment 8, which is carried out on bearings, is made in two symmetrical axes of the drain branch pipe of the vertical branches of perforated pipes with jet nozzles directed towards the tangential slit slots of the drain adapter pipe and drain nozzles directed toward the tangential slit slots of the drain adapter pipe with a jet nozzle directed towards the tangential slit slots of the drain plug pipe with a jet nozzle directed towards the tangential slit slots longitudinal slits.

The hydrocyclone (FIG. 3) comprises a housing 1 with an inlet nozzle 2 and a drain nozzle 3 with a bottom 4. The drain nozzle is made with tangential slit slots 5 (FIG. 6) and longitudinal slit slots 6 (FIG. 7) and contains mesh 7 fine cleaning.

The hydrocyclone is equipped with a spray wash tool 8 with jet nozzles 9 and additional slit slots 10, a lower bearing 11, a built-in eHHMM in the bottom 4 of the drain pipe 3, an upper bearing 12 fixed on the plate 13, a water supply pipe

14 with a coupling 15, a crane 16, a common water inlet pipe 17, a water intake chamber 18 equipped with an outlet pipe 19, a sand pipe 20, a hydraulic elevator 21, a water pipe 22 with a crane 23.

Hydrocycle.lon the first option works as follows. :

The drain pipe 3 is connected to the suction pipe of the pump and immersed in a stream of natural and wastewater, such as a river, an anankamer of large pumping stations, or a pool that accumulates waste water for reuse. After the pump unit is turned on, the fluid flow, having entered the hydrocyclone through the inlet nozzles 2, acquires a rotational motion. Solid particles with a density greater than the density of water, under the action of centrifugal forces are thrown into the sand pipe 8, and floating bodies and plankton with the water are directed toward the discharge pipe 3. Hydrocyclone flow, acting on the blades 10, causes the tubular casing to rotate 5 with a grid 7. Simultaneously with the launch of the pump, the taps 20 and 22 are opened and the working water is supplied to the branches

15 and 17, sorosmyvnogo means and hydraulic elevator 9. The working environment of the branch 15, derived from the slots 6, 16 and

through grid 7, deflects floating bodies and plankton and directs them along the current path of the cyclonic stream. Deviation of floating bodies and plankton and

moving them down to the sand, the nozzle 8 of the hydrocyclone enhances the impact of the jet of the outer branch 17, the slot of which is installed along the streamline of the cyclone flow. The mechanical impurities that have fallen into the sand pipe 8 are ejected by the hydraulic elevator 9 and are discharged below the intake valve.

In the second variant (Fig. 3), the flushing of floating bodies and plankton from the surface of the net is performed by means of a wash-wash tool B, made in the form of two symmetrical axes of the drain branch pipe of the vertical branches of perforated pipes. If the scrubbing agent 8 is placed inside a drain nozzle with tangential slits, flushing and deflection of the floating bodies is performed by the jet itself (Fig. 6). And if the scrubber 8 is located inside the drain nozzle with longitudinal slit slots 16, flushing and deflection of the floating bodies is produced by additional slit slots 10 in the sorbore tube directed perpendicular to the surface of the drain nozzle, and the jet nozzles 9 serve only to rotate the frame. The discarded floating bodies, having fallen into the zone of action of the peripheral descending flow, are carried away to the side of the sand pipe 20, and from there the hydraulic elevator 21 is pinched and transported to the zone below the pickup point.

The proposed hydrocyclone allows 3-4 times lower costs for the purification of natural and waste waters from mechanical impurities, floating bodies and plankton.
