Description

according to item 1, it’s necessary to cast apertures of a hemisphere or copo of paragraphs 1 and 2, in that it is equipped with additional diaphragms with nozzles while the diaphragms are mounted on the body with diffusers one angle to the other and have different shape.

The invention relates to fish farming, in particular, to devices for aerating water, and can be used for artificially saturating the atmosphere with oxygen of water in fishery and other water bodies. A device for aerating water in reservoirs is known, comprising a wing wheel, a half-cylinder housing covering the upper part of the wheel and a pipeline for supplying compressed air 1 under the housing. This device is placed mainly under the ice of the river, the winged column is activated by water pressure on its lower half, which limits its use by water bodies over. It is also known a device for aerating water in fish ponds, comprising a housing for supplying water, a mixing chamber to which said pipeline is tangentially connected, an air duct coaxially attached to the front side of the mixing chamber, and a chamber for crushing air bubbles radially fixed on it the inner surface of the blades, while at the outlet of the crushing chamber, the nozzle 2 is fixed. Despite the fact that in the crushing chamber air bubbles - are subjected to grinding to increase the surface of their contact with water, the known device does not provide aeration for large areas. The device for aeration of water is closest to the invention, including a housing For water supply, a perforated diaphragm and centrifugal centrifugal elements mounted in the apertures of the diaphragm will spruce in j. This device also has a mixing chamber and an air inlet. During operation of the device, water from the pump passes through a perforated diaphragm and is divided into separate streams, each of which results in an intense spin in a centrifugal water spray. The swirling flows of liquids have an ejecting capacity, which allows air through the air inlet pipe to get into the axial zone swirling. th stream. The limited volume of the mixing chamber does not allow the oxygen of the intake air to be completely dissolved in water, and intense turbulization inhibits the main flow. This results in a part of the air remaining unused and leaving the reservoir in the form of large bubbles. The water saturation efficiency decreases. The purpose of the invention is to increase the efficiency of aeration and increase efficiency. The goal is achieved by the fact that the device dp aeration of water, including a housing for supplying water, a perforated diaphragm, and centrifugal water dispensers installed in the openings of the latter, is additionally equipped with water jet nozzles, that the lines connecting their centers form closed figures — a quadrilateral or hexagons, with water jet nebulizers mounted at the center of these figures. In addition, it is advisable to make the diaphragms in the form of a hemisphere or a cone, and provide the device with additional diaphragms with sprays, while fixing the diaphragms on the body using diffusers at an angle to one another and perform various shapes. 1 shows a schematic of a device for aerating water; FIG. Figure 2 is a device in Fig. 1 with a diaphragm, the openings of which are arranged so that the lines connecting their centers form a figure in the form of a hexagon; in Fig. 3 it is a view A in Fig. 1: a device with a diaphragm with openings so that the lines connecting their centers form a quadrangular shape; 4 shows a device with a diaphragm in the shape of a semi-sphere; on fig.Z - the device with a diaphragm in the form of a cone; FIG. 6 shows a device with several diaphragms of a personal shape J in FIG. 7 is a view B in FIG. 6. A device for aerating CO water (ITO IT from the housing 1 for supplying water and the perforated removable diaphragm 3 connected to it by means of the diffuser 2 mounted on the diffuser 2 by means of a flange 4, water jet nozzles 5 and centrifugal atomizers 6 water, centrifugal atomizers 6 water located in the hole x 7 of the diaphragm 3, while the holes 7 are located so that the lines connecting their centers form closed shapes - hexagons (Fig. 2) S1I quadrilaterals (Fig. 3 ) while the jet nebulizers 5 water mounted the center of these figures. The diaphragm 3 can have either the shape of a hemisphere (Fig. L) or the shape of a cone (Fig. 5). In addition, several diaphragms 3 having different shapes and angled to one another can be mounted on housing 1 The water centrifugal sprayers 6 (Fig. 7) are formed by a set of plates 8 mounted at an angle to one another in the opening 7 of the diaphragm 3. The outer end of each plate 8 is welded to the edge of the opening 7, and their inner ends to one another. The diaphragm 3 is made of steel sheet with a thickness of 10 mm, and in the diaphragm 3, holes 7 are formed with a diameter of 70 mm and centrifugal razpiteli 6 are mounted in them. Water jet nebulizers 5 are holes with a diameter of 1.5 r 15 mm, which are made in the diaphragm 3. The device works as follows. Water from the pump through the housing 1 enters the diffuser 2, providing a uniform pressure field at the inlet to the jet nebulizers 5 and centrifugal nebulizers 6. The water, passing through the said pullers 5 and 6, is crushed into tiny droplets and, because the device is placed under the water in the pond , there is a maximum incidence of droplets formed by atmospheric air. With the same twist, the jets coming out of the centrifugal nozzles 6 with a spray angle that allow adjacent streams to contact (Fig. 1), intensive splitting of swirling jets into the smallest drops of 1-2 mm occurs (as they invariably collide with the same twist). The larger the contact area of air bubbles with water, the higher the saturation efficiency. The location of the jet distributors .5, which have a large supply of kinetic energy, in the center between the centrifugal atomizers 6 allows the water-air mixture to be dispersed over long distances, which increases the area of aeration. In addition, the location of the nozzles will provide a continuous spray. All this makes it possible to increase the efficiency of the device to saturate and improve efficiency. The implementation of a diaphragm in the form of a sphere or a cone allows you to place a larger number of raspipitel of equal performance, which allows you to increase the total area of the flare of the device, which contributes to the intensification of the process and increase productivity. This device is simple in design, convenient to operate, especially in the winter-spring period. In addition, the proposed device allows increasing the aeration area as compared with the known one by a factor of 1.5-2 and increasing the efficiency of saturation of water with oxygen at the same expenditure of energy resources. view A (desorder plates surcharge. holes x) Hexagonal cell b-tmm d 15mm
