The housing 1 is perforated in the upper part and provided along the outer perimeter to the perforation height by a compartment 9 for collecting water, the bottom 10 of which is located above the lower edge of the filtering load 2 of the housing 1, while the compartment 9 is connected to the outlet

The invention relates to water supply and to the structural embodiment of a device for drawing water from surface sources.

The purpose of the invention is to improve the quality of water purification.

FIG. 1 shows a device for collecting water from surface sources, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

The device for collecting water from surface sources contains a cylindrical body 1 with a filtering load 2 of granules with a density less than the density of water with a jetting goat 3. The body 1 contains a central perforated pipe 4 for supplying water from a source filled with a filtering load 5 from the granules in the fluidized bed the density is less than that of water, for example, half-expanded polystyrene, and having an inclined ellipsoidal socket 6 in the upper part outside the body 1, covered with a visor 3 and made minutes with an inclined grid 7, wherein the pipe 4 at the bottom of the grid is blocked and 8 derived beyond filter media for removal of slurry 2 to the bottom of the housing 1.

The continuously moving load 5 ensures that the fish are scared away from the device and prevents the grid 7 and the inner surface of the perforated tube 4 from clogging.

The housing 1 is perforated in the upper part and provided along the outer perimeter to the perforation height by a compartment 9 for collecting water, the bottom 10 of which is located above the lower edge of the filtering load 2 of the housing 1, while the compartment 9 is connected to the discharge pipe I 1.

Tubes 12 placed in the housing 1 are intended for transporting the filter loading, each of which has an ejector 13 in the upper part and a reflector 14 in the lower part, the pipes are connected to the discharge pipe 15, and the tampers 16 are located on the inner surface of the pipes 12 to intensify the impact of the granules between themselves and the removal of contaminants from their surface.

To prevent the formation of stagnant non-regenerable filter zones

5 of the load 2, as well as to ensure that the surface of the pipes 12 can be cleaned, the latter are installed in the housing inside the filter loading at a distance from the central vertical axis equal to 2/3 of the housing radius.

0 In the lower part of the housing 1, a valve 18 is placed in the open / go-through perforated pipe 17, freely moving between the upper and lower latches, and the fenders 19 to reflect and

g the change of the trajectory of the washed up granules of the filtering charge 2.

The visor 3 serves to prevent the mesh 7 from clogging up with litter and coarse suspended substances, creating increased speeds in the water intake zone and protecting

0 devices from floating objects.

The device works as follows. Water from the surface source passes through the grid 7 and through the socket 6 enters the central perforated pipe 4, where it is evenly distributed over

5 height of the filtering device. Water then enters the layer of filter loading and loading 2. Due to the fact that the lateral surface of water distribution in the central perforated pipe is significantly smaller than the surface of the perforated surface of the housing, the filtration rate decreases as the filtering load passes, which increases the water purification effect. The clarified water is collected in compartment 9 for collection.

5 and is discharged by a pipeline 11 to a water intake shore well of the water supply system.

Due to the vacuum created by the pump in the pipe 11, radial filtration takes place, at which the valve 18

0 is in the upper position and overlaps the cross section of the nozzle 17, preventing water from leaking from the bottom space. The bottom discharge layer, located under the compartment, is protective and prevents the contact of dirty water and

5 sediment accumulated in the bottom cone. Regeneration of the filtering load 2 is carried out continuously or periodically depending on the turbidity of the source water.

For this purpose, water from the coastal pumping station is supplied through the pressure pipe 15. The vacuum formed in the upper part of the Ejectors 13 ensures the capture of the floating filtering load 2, and the water pressure created in the ejectors 13 allows transporting the loading granule 2 to the lower conical part of the body 1 when the sludge accumulates exceed the buoyancy force of the valve 18, the latter is lowered onto the lower latches, thus opening the holes in the side surface of the nozzle 17. During this period, sediment is carried to the bottom of the watercourse and washed off by the flow. After the sediment is removed and the device is switched to filtering mode, the valve floats and again closes the outlet openings.

Thus, the proposed device provides high-quality washing of the filtering load without transporting the mine out of the watercourse limits, eliminates the use of special regenerating separate devices, improves the performance and reliability of fish protection with less A-A
