Description

The utility model relates to the protection of the aquatic environment and can be used for aeration of water bodies.

A device for aeration of water is known [Patent RU No. 2471724. - Published on January 10, 2013 Bull. No. 1], containing the pontoon anchored in the reservoir, equipped with a riser, lowered into the bottom layers of the reservoir, and a discharge pipe. The lifting pipe has a receiving nozzle for water inlet at the lower end, and its side walls above the nozzle have perforation, which is connected to the atmosphere by an air pipe equipped with a confuser to meet the atmospheric wind. The upper end of the water pipe is also equipped with a confuser with the possibility of using rollers in the conductor to orient it towards the atmospheric wind, passing into the guide pipe outside the outlet of the water pipe, which is connected to the discharge pipe through an annular water intake.

However, the known device has the disadvantage of low quality aeration of water, which, inter alia, depends on the wind pressure.

The technical result achieved by using the utility model is improving the quality of aeration of water.

The specified technical result is achieved by the fact that a mixing chamber equipped with a check valve is installed on the pontoon, which is made in the form of a hollow cylinder. A perforated nozzle is installed coaxially inside the mixing chamber. Inside the perforated nozzle, a swirler made in the form of a screw is installed. A water pump is installed between the water-lifting pipe and the mixing chamber, and a compressor equipped with an outlet pipe is installed on the pontoon. The compressor outlet pipe is connected to a cavity formed between the inner surface of the mixing chamber and the perforated pipe.

In FIG. 1 shows a General view of the device.

The device for aeration of water includes a pontoon 1, equipped with a lifting pipe 2, lowered into the bottom layers of the reservoir, and a discharge pipe 3. On the pontoon 1 is equipped with a check valve 4 mixing chamber 5, made in the form of a hollow cylinder. Inside the mixing chamber 5, a perforated pipe 6 is coaxially mounted, inside of which a swirler 7, made in the form of a screw, is installed. A water pump 8 is installed between the riser pipe 2 and the mixing chamber 5. In addition, a compressor 9 is installed on the pontoon 1, equipped with an outlet pipe 10. The outlet pipe 10 of the compressor 9 is connected to a cavity formed between the inner surface of the mixing chamber 5 and the perforated pipe 6.

A device for aeration of water works as follows. Turn on the water pump 8 and compressor 9. At the same time, the pressure created by compressor 9 should not be less than the pressure provided by pump 8. Using pump 8, water from the bottom layers of the reservoir through the riser pipe 2 installed on the pontoon 1 through the check valve 4 enters the internal cavity of the perforated nozzle 6 and, passing along the screw surface of the swirler 7, made in the form of a screw, receives a translational-rotational turbulent form of motion. From the inner cavity of the perforated nozzle 6, water through the perforation enters the cavity formed by the inner surface of the mixing chamber 5 and the perforated nozzle 6. In this case, water is mixed with air pumped through the compressor 9 through the outlet 10 into the cavity formed by the inner surface of the mixing chamber 5 and perforated pipe 6. Aerated water enters the reservoir from the mixing chamber 5 through the discharge pipe 3.

Placement on the pontoon of the mixing chamber, made in the form of a hollow cylinder, with a perforated nozzle coaxially mounted inside it, inside which a swirl made in the form of a screw is installed, and connecting the compressor outlet pipe to the cavity formed between the inner surface of the mixing chamber and the perforated nozzle, allows to ensure high-quality the process of saturation of water, which with the aid of a swirler moves in a turbulent state, by air supplied under pressure from a compress ora through the outlet pipe.

The presence of a water pump and compressor ensures the stability of the device, regardless of environmental parameters.
