INSTALLATION FOR TRANSPORTATION AND STORAGE OF WATER ORGANISMS

The inventive installation for transportation and storage of aquatic organisms relates to the field of cultivation of aquatic organisms, including fish, and in particular to devices for their transportation.

The main conditions for preserving the vital functions and commercial qualities of aquatic organisms during their transportation and storage are a sufficiently low temperature to slow down life processes (usually not more than 8 C) and the required level of dissolved oxygen in water.

A known method of transporting live fish in an airtight container with water and oxygen, in which to increase the oxygen supply and protect the tank from heating or cooling during transportation, a fully fluorinated organic compound with oxygen dissolved in it is added to the water, and the container is wrapped with metallic aluminum reflecting thermal rays film (application of the Russian Federation N ° 97118840, MNC 6 A 01K 61/00, publ. 10.10.1999).

The main disadvantages of plants that implement this method are, firstly, the need for organofluorine compounds and devices for their use and, secondly, the inability to control the oxygen content and water temperature when changing in a wide range of environmental parameters.

There is also a device-capacity “Nogrebk for storing and transporting fresh products, containing a housing in the form of external and internal containers, between which porous material is placed and liquid is poured, free evaporation of which allows cooling the internal for a long time

A 01 to 63/02 capacity and its contents (application of the Russian Federation No. 95101176, IPC 6 A 01 F

25/02, published on 02.20.1997).

The disadvantages of this device are, firstly, the inability to control the temperature of the products and, secondly, the inability to control the oxygen content in the internal container.

Closest to the claimed installation for transporting and storing aquatic organisms is a device for containing and transporting aquatic organisms, comprising a container for aquatic organisms and a closed circulation circuit with a pump and an oxygen saturation device, interconnected by pipelines, the suction and discharge sections of which are located respectively in the lower and the upper parts of the container, while the closed circulation circuit is connected to the supply system of liquid perfluororgan connection, and the suction and discharge sections of the pipeline and the circulation circuit are introduced into the container and equipped respectively with a perfluororganic compound intake and a filler (patent of the Russian Federation No. 2081576, IPC 6 A 01 K 61/00, A 01 K 63/02, publ. 20.06. 1997).

The main disadvantages of this device are, firstly, the need for the presence of organofluorine compounds and devices for its use and, secondly, the inability to maintain the required water temperature when changing in a wide range of ambient temperature.

The inventive installation solves the problem of transportation and storage of aquatic organisms at the required temperature of the aquatic environment and the content of oxygen dissolved in it when changing in a wide range of environmental parameters without the use of perfluororganic compounds and devices for its use.

2 thereby ensuring the structural simplicity and reliability of the installation, and

also a significant reduction in operating costs for its maintenance.

This problem is solved by the fact that the inventive installation for transportation and storage of aquatic organisms contains a control station, a container for aquatic organisms, serving the installation of the system, sensors of water temperature and oxygen content in it.

The container for aquatic organisms is provided with a lid having ventilation openings. The side walls and the bottom of the container are doubled to form a closed airtight container space in which porous permeable material is placed. Water is poured into the enclosed tight space of the container, above which a gas cavity forms. The container for aquatic organisms and its coating is covered with a heat-insulating layer.

The unit is serviced by a cooling system with a vacuum pump, a heater and an aeration system with an air atomizer.

The cooling system through pipelines and valves sequentially connects the gas cavity of the closed sealed container space with a vacuum pump and with the space under the container cover.

The heater is located in the lower part of the enclosed tight space of the container.

The aeration system through pipelines and valves sequentially connects atmospheric air with a vacuum pump and with a spray located in the lower inner cavity of the container.

Sensors for water temperature and oxygen content are located in the inner cavity of the container.

The listed sets of general and distinctive essential features ensure the achievement of the claimed technical results in all cases to which the requested amount of legal protection applies.

Providing a vacuum pump for the transport and storage of aquatic organisms with a vacuum pump allows intensive evaporation and cooling of water in a closed airtight container space, since each value of the pressure of water vapor in a saturated state corresponds to a certain temperature of steam and water, for example, + 1.2 C at 5 mmHg and -17.3 ° С at 1 mmHg (see Rivkin S.L., Aleksandrov A.A. “Thermophysical properties of water and water vapor, Moscow: Energia, 1980). This allows, by changing the degree of evacuation, to control the temperature of the water in the cavity of the container. In this case, the direction of the pumped condensate (i.e., distilled water) into the container cavity allows, on the one hand, to compensate for the loss of water in the internal tank due to evaporation, and on the other hand, to avoid a number of problems when it is released into the environment.

Providing a unit for transporting and storing aquatic organisms with a water heater located in the lower part of the enclosed tight space of the container allows maintaining the required water temperature for aquatic organisms with an excessive decrease in the ambient temperature.

The supply of the installation for transportation and storage of aquatic organisms with an aeration system with an air atomizer allows using the same vacuum rV /.

the pump, as a compressor, maintain the necessary oxygen content in the water to maintain the life of aquatic organisms.

The coating of the container for aquatic organisms and its lid with a heat-insulating layer allows to reduce heat transfer between the internal volume of the container and the external environment and, accordingly, to reduce the operating time of the vacuum pump to maintain the required temperature in the internal container.

The drawing schematically shows an installation for transporting and storing aquatic organisms.

Installation for transportation and storage of aquatic organisms contains a control station 1, a container for aquatic organisms 2, a cooling system 3, a water heater 4, an aeration system 5, water temperature sensors 6 and oxygen content sensors 7.

The container for aquatic organisms 2 is provided with a lid 8 having at least one ventilation opening 9. The side walls and the bottom of the container for aquatic organisms 2 are doubled to form a closed airtight space of the container 10, in which porous water-permeable material 11 is placed. In the closed airtight space of the container 10 filled with water with the formation of a gas cavity above its surface 12. The container for aquatic organisms 2 and its lid 8 are covered with a heat-insulating layer 13.

The cooling system 3 through pipelines and valves 14 and 15 sequentially connects the gas cavity 12 of the closed sealed space of the container 10 with a vacuum pump 16 and with the space 17 under the attachment of the container 8.

The water heater 4 is placed in the lower part of the enclosed sealed space of the container 10. The aeration system 5 by means of pipelines and vets 18 and 19

sequentially connects atmospheric air with a vacuum pump 16 and an air atomizer 20 located in the lower part of the inner cavity of the container.

Installation for transportation and storage of aquatic organisms works as follows.

When the temperature of the water located in the inner cavity of the container is increased, the water temperature sensor 6 is activated, the vacuum pump 16 is turned on, the valves 14 and 15 are opened and, when the valves 18 and 19 are closed, the gas cavity 12 is evacuated while condensate is discharged into the space 17 under the lid of the container 8.

When the temperature of the water in the container cavity falls below the permissible norm, heater 4 is turned on.

When the oxygen content in the water in the container cavity is lower than the permissible norm, the sensor 7 switches off, the vacuum pump 16 is turned on, the valves 18 and 19 open and, when the valves 14 and 15 are closed, atmospheric air is supplied through the air atomizer 20 to the water in the internal cavity of the container.

The inventive installation for transportation and storage of aquatic organisms is reliable and simple and provides automatic maintenance of the water temperature and oxygen content necessary for aquatic organisms under conditions of variation in a wide range of environmental parameters.
