На фиг. 1 изображено предлагаемое устройство, разрез; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - разрез Б-Б на фиг.1.FIG. 1 shows the proposed device, the cut; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG.

Устройство содержит кожух 1, внутри которого размещен полый вертикальный вал 2 с отверсти г/ш 3 дл  пропуска воздуха. На нижнем конце вала укреплен ротор, состо щий из двух дисков 4 и 5 и расположенных между ними лопаток 6, при этом периферийные участки дисков 4 и 5 отогнуты с .образованием канала дл  прохода воздуха , а в последнем установлены пластины 7. Под ротором размещен статор, образованный двум  концентрично установленными кольцами & и 9, межлУ которыми закреплены дополнительные лопатки 10.The device comprises a casing 1, inside of which a hollow vertical shaft 2 with holes g / w 3 is placed for air passage. At the lower end of the shaft a rotor is hardened, consisting of two disks 4 and 5 and blades 6 located between them, while the peripheral sections of disks 4 and 5 are bent to form an air passage channel, and in the latter there are plates 7. A stator is placed under the rotor formed by two concentrically mounted rings & and 9, between which are fixed additional blades 10.

Кожух 1 выполнен в виде цилиндра и закреплен на опоре, например понтоне 11, и имеет патрубок 12 дл  сообщени - его полости с атмосферой. Ротор укреплен на валу 2 с помощью кольца 13 и перемычек 14 так, что между,диском 4 и кольцом 13 образована щель дл  прохода воздуха из вала 2 в пространство между диска1/и -4 и 5.The casing 1 is made in the form of a cylinder and is fixed on a support, for example a pontoon 11, and has a nozzle 12 for communication - its cavity with the atmosphere. The rotor is mounted on the shaft 2 by means of a ring 13 and jumpers 14 so that between, the disk 4 and the ring 13 is formed a gap for the passage of air from the shaft 2 into the space between the disk 1 / and-4 and 5.

Привод устройства осуществлен от двигател  15, а статор св зан с кожухом 1 кронштейнами 16.The device is driven from the engine 15, and the stator is connected to the casing 1 by brackets 16.

Устройство работает следующим образом .The device works as follows.

При вращении вала 2 в ротор с боль шой скоростью поступает вода. Между диском 5 и кольцом 13 возникает зона пониженного давлени , в которую из полости вала 2 поступает воздух. В полость вала 2 воздух поступает через патрубок 12 и кожух 1. Смесь воды и воздуха проходит между дисками 4 и 5 и направл етс  вниз где встреча тс  с дополнительными лопатками 10 статвра. В результате взаимодействий с дополнительными лопатками 10 c-nfexopa поступающий воздух дробитс  на большое количество мелких пузырьков , которые интенсивно перемешиваютс  с водой и медленно вспылывают на поверхностЗ водоема- Между воздуXDM , закрепленным в пузырьки, и окржающей их водой происходит процесс массообмена, в-результате которого вода насыщаетс  кислородом, необходимым дл  дыхани  рыбы, обитающей в водоеме.When the shaft 2 rotates, water enters the rotor at high speed. Between the disk 5 and the ring 13, a zone of reduced pressure occurs, into which air flows from the cavity of the shaft 2. Air enters the cavity of the shaft 2 through the pipe 12 and the casing 1. A mixture of water and air passes between the disks 4 and 5 and is directed downwards where it meets with the additional blades of the 10 statrav. As a result of interactions with additional blades of 10 c-nfexopa, the incoming air is crushed into a large number of small bubbles, which are intensively mixed with water and slowly float up on the surface of the reservoir. the water is saturated with oxygen, which is necessary for the respiration of fish living in the reservoir.

Использование ротора, кра  диско которого загнуты вниз и между которыми закреплены пластины, а также статора, выполненного в виде двух концентрично расположенных колец, между которыми закреплены дополнительные лопатки, аналогичные упом нутым пластинам, позвол ет создать устройство, которое насыщает воду кислородом воздуха более эффективно чем известные, так как оно создает большую поверхность контакта между водой и воздухом.The use of a rotor, the disco edges of which are bent down and between which plates are fixed, as well as a stator, made in the form of two concentrically arranged rings, between which additional blades, similar to the said plates, are attached, makes it possible to create a device that saturates water with air oxygen more efficiently than known as it creates a large contact surface between water and air.

Предлагаемое устройство позволит предотвратить гибель большого количества товарной рыбы и молоди в рыбоводных прудах в летнее и зимнее врем .The proposed device will prevent the death of a large number of marketable fish and fry in fish ponds in summer and winter.

Экономический эффект от использовани  одного устройства составит 8,5 тыс,руб. в год.The economic effect from using one device is 8.5 thousand rubles. in year.
