4. The apparatus of claim 1, in that it comprises a heater with a fan for supplying air to the cooling tower.

The invention relates to fish farming, in particular, to j devices for aerating water, feeding felts, fertilizing, treating and harvesting fish in fish ponds.

It is known a device for aeration:, water in fish ponds, consists of a supply system: and compressed air, an air purification system located in a reservoir of a perforated pipeline formed from separate elastic sections with covers made of synthetic fabric, floats of Korea, attached to the pipeline by means of autoHOM-roix, height-adjustable, flexible connections 1.

The drawbacks of the device are the complexity of the design, due to the use of the compressor, the system of air purification from oil, the float and Korea system to maintain the pipeline at a certain depth of the reservoir, the complexity of maintenance and repair in the winter and summer periods, and the low efficiency of large amounts of energy to overcome hydraulic resistance by air. along the length of the pipelines and 3 holes of perforated pipes and pipelines, a weak saturation of water with air, due to the short time of contact of air bubbles, with It also has a low versatility of the device in terms of its simultaneous use for other activities that contribute to increasing fish productivity in the reservoir, in particular, treating fish diseases, feeding, regulating the chemical and physical condition of the water, alleviating the conditions and increasing fish production by attracting fishing gear

It is also known a device for aerating water is the simplest to operate and consists of a pressure pipe for supplying water to the mixing chamber, bladder, nozzle, and blades for turning the flow of water and crushing air bubbles 2,

However, the known device requires a lot of energy with a small distance of propagation of the front of aerated water (low aeration capacity), due to. a large hydraulic resistance., by the mixing chamber, by the presence of blades for spinning the flow of water, by the nozzle, and also by the violation of the conditions for organizing a submerged free jet.

In addition, in the known device, the process of dissolving air in water is not sufficiently intensified due to the short time and small surface of air-water interaction.

The device cannot be used for other activities that contribute to the fish productivity of the reservoir and, in particular, to treat fish diseases, feed, regulate the chemical and physical condition of the water, alleviate conditions and increase fish production by attracting it to the fishing spot.

Closest to the proposed technical essence. is a device for distribution of feed, fertilization and aeration of water in fish in aquatic reservoirs, including feed and fertilizer bins, equipped with a agitator, a tank for preparing a fertilizer solution and a discharge pipe on which the nozzles are installed.

All equipment known devices: mounted on a self-propelled floating catamaran fS.

However, when this device is in operation, the water is also slightly saturated with oxygen due to the insignificant time and the surface of water contact with air, and the depth of distribution of aerated water has a plateau, since aeration is performed superficially without mixing with deep layers of the reservoir.

The device can not be used in the winter because of the large. i supercooling of water during spraying and the difficulty of moving it in freezing conditions.

In addition, the well-known device cannot be used to treat fish or attract them to the place of harvest, which reduces its functionality.

The aim of the invention is to intensify the process of dissolving air in water, increasing the depth of distribution of aerated water and applied substances, and expanding the functionality.

The goal is achieved by the fact that the device for distribution of feed, fertilization and aeration of water in fish ponds, including feed and fertilizer hoppers, equipped with agitators, a tank for preparing a fertilizer solution and a pressure pipe, on which the nozzles are installed, is equipped with a d) pool with for collecting aerated water, a hopper with agitator for drugs, a container for preparing solutions of drugs and a pump with a piping system to supply aerated water from b sseyna in the vessel for preparing solutions of fertilizers and medicinal preparations hopper and container smontirogvany above the pool and the discharge conduit is connected to the latter. In addition, it is advisable to strengthen the discharge pipeline so that the nozzles are immersed in water, the nozzle length should be made greater than the distance between the jet pole and its initial cross section.

o In this case, it is advisable to provide the device with a collapsible heat-insulated chamber to accommodate all the components of the device.

In addition, it is advisable to provide the device with a heater with a fan for supplying air to the cooling tower.

j In FIG. 1, a schematic representation of the proposed device is shown; , FIG. 2. Attachments with jet streaming out of it. Device for dispensing feed, fertilizing and aerating water

in fish ponds includes a cooling tower 1 with a pool 2 for collecting aerated water, mounted above the basin 2 bins 3,4 and 5, respectively, for fertilizers, and drugs, equipped with agitators b located under the bunkers 3 and 5, tanks 7 and 8 for preparing fertilizer solutions and drugs, pump 9 with pipelines 10 and 11 for supplying aerated water from pool 2 to tank 7 and 8 through zadvshski

12, bactericidal machine 13, heater 14, fan 15 for supplying air to cooling tower 1, and also discharge pipe 16 with nozzle 17 connected to the pool

2 for aerated water, either through pump 18, or through a conduit .19 with valve 20.

For supplying water to the cooling tower 1, the device has a pump 21 with a WM 22 and a suction suction unit. 23 pipelines, the last of which is installed nozzles 24.

All units of the device are enclosed in a heat-insulated chamber 25.

The nozzles 17 are reinforced on the injection pipe 16 by means of a swivel 26, which allows the nozzle 17 to rotate vertically and horizontally.

The proposed device works

in the following way.

The water pump 21 .. is turned on and the water from the reservoir enters the nozzles 24, by means of which it is sprayed onto the cooling tower shields 1. The leaks

on the shields, the water is exhausted by the oxygen of the air blown by the fan 15. During the cold season, the air is heated by the heater 14. The aerated water flows into

pool 2. In cases where pool 2 is flush with or below the pond, aerated water is supplied from pool 2 to nozzle 17

pump 18. In those cases, when the pool is located above the reservoir level, the aerated species is fed to the nozzle 17 by gravity through a pipeline, 19 through the valve 20. By turning the nozzle 17 AROUND

The hinge coupling 26 provides for the supply of aerated water to any point and, to any depth of the reservoir.

Fertilization and curative

solutions in the reservoir is carried out in the following sequence.

Pump 9 is turned on and aerated water is supplied to tanks 7 and 8 through valves 12. Then, in the same

containers from bins 3 and 5 are served with food and medicinal preparations. After obtaining the solutions of the required concentrations, they are drained into pool 2, and from there through nozzles

1 in the reservoir. Uniform distribution of fertilizers and medical solutions over the reservoir is achieved by turning the nozzle 17 in the plane of the lake mirror. To disinfect water from parasites and lakes

(fungi, trichodins, chilodonellas) the bactericidal machine 13 is turned on, equipped with a source of ultraviolet radiation.

Entering feed into the pond is accomplished by feeding it from the hopper.

4 to pool 2 and from there through nozzles 17 to the specified area of the reservoir. To avoid mixing the feed with the ground, the bottom of this zone should be coated with a polymer material.

The device can be used to attract fish to the site; installation of fishing gear. This is achieved by orienting the jet to the place of fishing. Fish are attracted to the flow of water. The pipe 16 is fixed so that the nozzles 17 are immersed in water, and the nozzles 17 can be located either at the level of the water surface or lower, depending on the depth of the reservoir. If the reservoir is not deep, the nozzles 17 can be made B in the form of a narrow slit, and. The jet should be directed to the level with the surface of the water in order to avoid sediment dragging up. The length of the nozzle 17 is chosen two or more times larger than the distance between the jet pole and the head 1. Its diameter is {(fig 2). one

It is especially important to withstand this: condition in those cases when the pipeline :; 16 plots dinene to the nozzle 17 at an angle of 30-90 (as shown in the drawing). In these cases, due to increased flow flow at the inlet to the nozzles, the hydraulic resistance increases, the condition of uniformity of the velocity support 3 output section of the nozzle and the destruction of the jet structure is violated, HacajioK 17 is made in the form of short: . CREATING WITH ZOZOD5-I submerged jet

providing aerated water, feed, fertilizers and medical solutions to any plateau of the reservoir.

For feeding fish offer. s / the device should use granulated feed coated with a protective film that is resistant to damage.

The device is stationary mounted on the shore of a reservoir and therefore does not require large amounts of energy, since it has the need to move it around the reservoir.

The device is characterized by a greater nonstification of the air dissolution process in Bode, as a result of a dramatic increase in time and surface contact of water with air when flowing through the cooling tower shields. The increase in time and contact surface is achieved by selecting the number and size of shields,

Especially effective is the use of the proposed device for ponds with geothermal water sources. In this case, along with water aeration, the source water is cooled to the water temperature in the water (pond, lake),

The versatility of using the device in terms of its simultaneous use for other works is increased, contributing to the enhancement of the fish productivity of the reservoir to the treatment of fish, as well as alleviating the conditions and increasing the amount of fish by attracting it to the fishing spot with the help of a submerged free jet.
