The invention relates to hydraulic engineering and can be used for automatic water purification from suspended and bottom sediments and podzaborno device [1], comprising a cylindrical drum with a perforated sheet side panels mounted end to the intake end rotatably, and seroochistki device made in the form of a spring-loaded cutters, interacting with the covering with a sharp edge, while the cutters are provided with channels with nozzles connected to a source of water pressure, and nozzle channels is directed into the zone of interaction between the sharp edges of the cutters with the skin of a drum.

The disadvantages of this known device:

the failure to clean nanocapsule flow from suspended sediments with a diameter smaller than the characteristic linear dimension of the holes of the perforated wall, as a jet of water supplied by a pump through pipes through the nozzle to the surface of the drum, interact with nanoanalysis flow and do not contribute to the specified clearance, i.e., the load of the considered fraction enter the inside of the drum and forth in the intake channel;

the accumulation at the bottom of the drum, suspended sediment diameter greater than the characteristic linear dimension of the holes of the perforated walls and bottom sediment (result - dam sediments of the lower part of the drum, a possible jamming, i.e., stop);

energy for driving the pump, supplying water to the drum surface.

The closest in technical essence to the proposed treatment is the intake device [2], including specified in the watercourse cleaning cylinder, the side surface of which is made permeable, and exhaust valves associated with one of the grounds of the treatment cylinder, with the longitudinal axis of the cylinder is parallel to the direction of flow, and the device is equipped with a flat shutter mounted on the outlet lines in the input part, and a driven rotation of the cleaning cylinder, made in the form of a turbine, with the cylinder installed in the coastal niche watercourse with the possibility of rotation around the longitudinal axis, the bottom coastal niches arranged above the bottom of the watercourse and with a turn in his direction, and a discharge pipe provided with a supporting shaft mounted in its input section, and a pair of pipe with base treatment made telescopic cylinder, while the cylinder is made with a diameter larger than a diameter of the discharge line.

The disadvantage of this device is inefficient use of transverse circulation for purification of water from sediment at the intake, also decided the sharp attenuation of the cross-stream circulation and reduce distractions from the surface of the cylinder efforts acting on particles suspended sediments, and secondly, the maximum possible depth treatment of the cylinder in the flow, which affects its rotation, i.e., sewage treatment capacity as a result of exposure to benthic sediment.

The purpose of the invention is improving the efficiency of water purification from the sediment at the intake by creating efforts, distracting mechanical particles from the drum surface, by providing the transverse circulation.

This objective is achieved in that the water-purifier comprising a supply channel and located in parallel to the direction of water flow mesh cylindrical drum, one end telescopically mounted on the intake pipe for rotation with the help of the mounted inside the drum turbine, equipped with an additional intake pipe and installed it mesh cylindrical drum, supports arranged at the bottom of the inlet channel, avankamera, receiving top hosts named intake tube and made flush holes, vent pipe communicated with said leaching holes, and the catastrophic threshold, moreover, mesh cylindrical drums facing the possibility of rotation in the same direction and with the corrugated outer surface and mounted in parallel to one another so that the protrusions on the surface of one of the drum correspond to the depressions on the surface of the other drum.

This embodiment of the intake-purifier allows you to increase the transport capacity of the flow, i.e. flow increase bottom sediment to proryvnym holes (due to the one-way, for example, clockwise rotation of the treatment drum), and improve cleanup thread from suspended sediments, in particular the depletion of the Central zone between the rotating drums suspended sediments and increase distracting from the surface of the rotating drum forces acting on particles suspended sediments (due to the execution of the drum surface corrugated shape with mutually opposite placement of the projections and depressions).

In Fig. 1 shows a water-purifier in plan; Fig.2 - section a-a in Fig.1, in Fig. 3 - section b-B in Fig. 1, in Fig. 4 in an enlarged scale opposite the location of the tabs on one drum and depressions on the other drum. To simplify the graphs in Fig. 1, 2 and 3 are not shown, the protrusions and depressions on the surfaces of the drums, and Fig. 4 shows the cellular structure of the mesh drum surface.

Vodozabornaya water flow, lowered below its level and mounted for rotation around axis 3 by means mounted within the drum 1 turbine 4. Each of the drums 1 is telescopically one end corresponding to the intake pipe 5, is placed into the recipient top avancuara 6, hydraulically connected to the suction pipe 7 pumps, and turned towards the water opposite the intake pipe 5 end mounted on a support 8, which is located on the bottom 9 of the inlet channel 2.

At the bottom of the top avancuara 6 are flush holes 10 provided with discharge slurry pipe 11. Drums 1 made with the possibility of rotation around 3 axes in the same direction, e.g. clockwise, and with a corrugated outer surface, and are mounted parallel to one another, so that the protrusions 12 on the surface of one of the drum 1 correspond to the depressions 13 on the other surface of the drum 1.

The bottom 9 of the inlet channel 2, over which is placed the reels 1, made in the form, for example, a semi-circular tray below each drum 1 with an increased bias to proryvnym holes 10 in its lower part with a pair of trays in the form of the barrier ribs 14 on the whole length of the bottom 9 with horizontal B6, arranged sequentially arranged one after another catastrophic threshold 15 and reset 16 to remove litter.

Water-purifier works as follows.

Water sediment in the inlet channel 2 comes to cleaning the mesh of the cylindrical drum 1 and through turbines 4 leads them in the same directional rotation around 3 axes.

Rotating drums 1 is formed in the flow cross-circulation, resulting vectors which during the rotation of both reels 1 clockwise directed to proryvnym holes 10, through which the bottom sediments are redistributed favorable with increased transport their ability to proryvnym holes 10. Specified redistribution of bottom sediments is facilitated by the presence of the barrier ribs 14 (on the entire length of the bottom 9) with a horizontal top.

The presence of mutually opposite projections 12 and depressions 13 on the filter surfaces of the rotating drums 1 leads to the formation between the Central zone, depleted by suspended sediment and to increase distracting from the surface of the rotating drum 1 forces acting on particles suspended sediments. In the field number from the bottom 9 to the surface of not less than 1,072 0,003 times, and in the field sistanizadeh currents between the right drum 1 and the right side of the inlet channel 2 turbidity flow decreases from the bottom 9 to the surface of at least 1,063 0,004 times, there is an increase in shear stress on the average not less than 1,022 times, i.e., increases the transport capacity of the stream.

Purified water (with a small part of suspended sediment diameters less than the characteristic linear dimension of the cell mesh drum surface 1) of the internal cavity of the rotary drum 1 through the intake pipe 5 to the receiving end enters the avankamera 6 and thence to the intake pipe 7 of the pump to the consumer. Wash water (from bottom sediments, pereraspredeleniya, in particular, with the separation of the ribs 14 with a horizontal top, and with a significant part of the sediment diameters, mainly more than the characteristic linear dimension of the cell mesh drum surface 1) rushes past the supports 8 and the bottom 9 to proryvnym holes 10 and thence through the waste pipe 11 to reset.

If necessary floating litter with excess water is removed through the catastrophic threshold of 15 and reset 16 back into the water source.

In the Chenin diameter of load is not less than 1.32 0.04 times in purified water in comparison with the same parameters for the inlet channel 2.

Water-purifier comprising a supply channel and located in parallel to the direction of water flow mesh cylindrical drum, one face telescopically mounted on the intake pipe for rotation with the help of the mounted inside the drum turbine, characterized in that it is provided with an additional intake pipe and installed it mesh cylindrical drum, supports arranged at the bottom of the inlet channel, avankamera, receiving top hosts named intake tube and made flush holes, vent pipe communicated with said leaching holes, and the catastrophic threshold, moreover, mesh cylindrical drums turned towards the water opposite the intake pipe ends, mounted on supports made with the possibility of rotation in the same direction and with the corrugated outer surface and mounted in parallel to one another so that the protrusions on the surface of one of the drum correspond to the depressions on the surface of the other drum.

SUBSTANCE: invention is designed to draw off young fish from zone of influence of water diversion front. Method comes to ejecting young fish into intake part of ejecting plant from section of pond with higher concentration of young fish, creating active ejecting working stream in mixing chamber by entraining volume of water containing young fish into stream created by central ejecting hydraulic jet and further conveyance of water-fish mixture along pressure conduit into fish outlet. At the last stage of conveyance young fish is transported into fish outlet under no pressure conditions by forming hydraulic jet angle to trough of fish outlet, young fish being dropped on surface of fish outlet stream. Invention provides effective conditions for drawing off young fish into fish outlet and reduces damage to young fish. If working ejecting stream is preliminarily saturated with atmospheric air, its outer borders are saturated with air in form of finest microbubbles which form boundary layer ("air cushion") at contact with which young fish do not suffer from discomfort and easily take up hydrodynamic pressure built in mixing chamber. Moreover, provision of boundary layer saturated with microbubbles of air makes it possible to considerably reduce value of friction coupling of two streams, main getting from working nozzle and ejecting, containing young fish.
