Description

The invention relates to the technique of water saturation of fish ponds with oxygen from the air, as well as for aeration of wastewater.

A jet jet aerator is known, comprising a housing, a water inlet, a suction inlet, a mixing chamber and a conical nozzle, the suction inlet and the mixing chamber being made of two parts and provided with connecting parts of corrugated elements of elastic material, for example rubber.

The known device intensifies the process of saturation of water with oxygen in the air in a limited volume, which is due to the peculiarities of its design.

The purpose of the invention is to intensify the process of saturating water with oxygen in the air and increasing the volume of saturable water.

This is achieved in that a jet aerator comprising a housing, a water inlet nozzle, a suction nozzle and an displacement chamber made of two parts and having corrugated elements made of elastic material, such as rubber, are connected to the movable part of the mixing chamber. the mixture, comprising a housing with an inlet channel and concentric located in it cut-off valves, made in the form of truncated cones.

the smaller bases of which are directed toward the body, the conical surfaces of the cutters being formed by the rays emanating from the top of the angle of the flare of the water-air mixture.

Connecting a water-air mixture to the moving part of the mixing chamber, comprising a housing with an inlet channel and cutters concentrically arranged in it, made in the form of truncated cones, the smaller bases of which are directed toward the housing, and the conical surfaces of the cutoffs are formed by rays emanating from the top of the opening angle torch, provides an intensification of the process of water saturation with oxygen from the air and an increase in the volume of saturable water.

FIG. 1 shows the aerator, general view; in fig. 2 - the same, longitudinal section.

The aerator contains a tank 1 mounted on the frame 2, a pump 3 with suction and pressure pipes 4 and 5 and attached to the tank 1 by means of a rigid connection 6 aerator. The aerator consists of a housing 7 with a nozzle 8 for supplying water, a suction nozzle and a mixing chamber arranged coaxially with each other.

The suction nozzle consists of fixed and movable parts 9 and 10, connected by a corrugated element 11 made of an elastic material, for example rubber. The input end of the fixed part 9 of the suction nozzle is located outside the housing 7, and the output end of the movable part 10 of the suction nozzle is located in the mixing chamber so that an annular gap 12 is formed between them.

The mixing chamber consists of fixed and movable parts 13 and 14 connected by a corrugated element 15 made of an elastic material. To the movable part 14 of the mixing chamber, the case of an air-air mixture is connected, comprising a case 16 and compartments 17 20 concentrically arranged in it, made in the form of truncated cones, the smaller bases of which are directed toward the case 16. In this case, the conical surfaces of the cutters are formed by rays, the outcome from the top of the flare angle of the water / air mixture.

The aerator works as follows.

The tank 1 is filled with water so that the water level is 200-250 mm below the end of the central inlet duct 21 of the sprayer. Include the pump 3. Water from the tank 1 through the suction pipe 4, the pump 3, the pressure pipe 5 and the pipe 8 for

water supply enters the cavity of the ejector body 7. The movement of water in the body cavity has a turbulent character, and the suction nozzle consists of a fixed

9 and 10 movable parts connected by an elastic corrugated element 11, therefore, when water passes through the annular slot 12, the movable part 10 of the suction nozzle makes random oscillations in different directions. At the same time, the speed and dimensions of the annular flow passing through the annular gap 12 are constantly changing. The passage through the annular slot 12, the flow of water is in contact with the air in the mixing chamber, directly in front of the movable part 10 of the suction nozzle. So, the moving part 10 of the suction nozzle makes random

vibrations, the water flows from the air are mixed in the mixing chamber, forming a stream of water-air mixture. At the place of air entrained by the flow of water through the intake pipe enters the air from the atmosphere. The water-air mixture then goes to the water-air mixture dispenser, with some of the jet passing through the central inlet 21, and the other part of the jet is cut off by the edge of the shutter 17. A similar cut off of the flow is carried out by the shut-off devices 18, 19, 20. Due to this, the air-air mixture separates into equal volumes, which, evenly expanding, are distributed over the cross section

expiration of one of the stream.

Through the nebulizer, the stream of water-air mixture is released into the atmosphere, additionally trapping air from the atmosphere, and entering the aerated water, saturating it with oxygen. In this case, since the mixing chamber consists of two parts interconnected by an elastic corrugated element 15, and the flow of the water-air mixture in the mixing chamber is turbulent, the movable part 14 of the mixing chamber, rigidly connected to the sprayer body 16, makes chaotic oscillatory movements in different directions. Therefore

the volume of water saturated with air oxygen increases significantly.

The invention makes it possible to increase the intensification of the process of saturating water with oxygen and to increase the volume of injected water.
