Description

FIELD: fish farming.

A device is known for aerating water in fish ponds, consisting of a compressed air supply system placed in a pond of perforated piping formed from separate sections, floats and barkers attached to the latter by means of flexible connections.

The aim of the invention is to provide installation of the device at a depth in a horizontal position regardless of the bottom topography. For this, in the proposed device, the pipeline sections are arranged radially, and the flexible connections are made autonomously with the possibility of their height adjustment.

The sections of the pipeline are made of elastic, interconnected by means of a radial cross and have covers made of synthetic fabric.

In addition, the compressed air supply system is equipped with coarse and fine filters of the latter.

FIG. 1 shows schematically the described device, a general view; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 is a view along arrow B in FIG. 2; in fig. 4 shows a section along BB in FIG. 2

The device consists of a compressed air supply system 1, filters 2 and 3 coarse and

fine cleaning of the last perforated pipeline; - 4. formed from separate sections 5, half of the stands 6 and korea 7, attached to the latter by means of flexible

communication 8.

Section 5 of the pipeline is made of elastic, interconnected by means of a radial cross 9 through fittings 10 and have covers 1 1 of synthetic fabric.

The radial cross 9 by nozzle 12 is connected to the collector 13.

Pipeline sections 5 are located radially, and flexible connections 8 are autonomously made with the possibility of height adjustment.

The coarse air filter 2 has a spiral 1-i inside, and the fine filter 3 has a removable cartridge 15 with activated carbon.

Pipeline 4 is placed in water and is kept from ascending by cork 7 with gpb connections 8 and from floats 6 to lowering to the bottom. The device operates as follows. Compressed air is supplied to the coarse filter 2, where homogeneous premixes are thrown by the centrifugal forces of the air flow swirled by the coil 14 onto its walls and flow down to the bottom of the internal cavity of the filter, from where they are periodically removed through the faucet. In the TOUKOII purification filter 3, the impurities are adsorbed by activated carbon.

Then, the air and the collector are iodized in section 5 of the perforated pipeline, where it, discharging through the fabric of the cover 11, is dispersed, creating a developed contact surface, which ensures the diffusion of oxygen into the water column.

The air pressure in the system is monitored by pressure gauges.

Before submerging the perforation of the pipeline 4 into the reservoir, the length of the flexible connections 8 is adjusted so that the sections 5 of the pipeline are located at the required depth and they have non-regs.
