Description

 The invention is in the field of fish farming and can be used for the maintenance of aquatic organisms, as well as for their transportation both on-farm and over long distances.

 A device for keeping and transporting fish (ed. St. USSR N 1210758 IPC 6 A 01 K 63/02, 1986), containing a container for fish with a lid and a discharge device and two water circuits, one of which includes a pipeline connecting the pump, a cleaning filter and an aeration device, and another intake pipe connected to the pump and a water supply nozzle connected to the pressure pipe of the pump.

 The operation of this device is associated with significant energy costs due to the large turnover of water, which provides the necessary water treatment and oxygen saturation.

 Closest to the claimed is a device for long-term maintenance and transportation of aquatic organisms (ed. St. USSR N 963488 IPC 6 A 01 K 63/02, 1982), consisting of a container for aquatic organisms and a closed circulation circuit, including a pump and an ozonizer, connected interconnected piping systems, the suction and discharge sections of which are located respectively in the lower and upper parts of the container.

 In addition, the device is equipped with a pollution collection chamber with a valve for unloading them, which reduces the required water flow in the circulation circuit and thereby reduces the energy consumption of the device.

 However, this known device is difficult to operate due to the need to control the valves of the chamber to collect contaminants. In addition, the presence of a pollution collection chamber is justified for large container volumes and makes it difficult to use the device when transporting fish by air.

 In this known device, a closed loop is designed to circulate water in order to purify and saturate it with oxygen.

 But at the same time, it does not achieve the removal of ammonia and carbon dioxide from water, which reduces the quality of water and, as a result, worsens the conditions of keeping fish.

 This invention is aimed at providing such technical results as improving water quality and increasing the efficiency of the device by reducing the power consumption of the pumps and simplifying the design.

 To achieve these results, in a device for the maintenance and transportation of aquatic organisms, consisting of a container for aquatic organisms and a closed circulation circuit, including a pump and aeration device, interconnected by a pipeline system, the suction and discharge sections of which are located respectively in the lower and upper parts of the container, the circulation circuit is connected to the feed system of liquid perfluororganic compounds (PFOS), and the suction and discharge sections of the pipelines the circulation circuit is introduced into the container and equipped respectively with a PFOS intake (or collector) and a spray.

 It is advisable to introduce an expansion tank into the circulation circuit for separation from PFOS in the process of circulation of gas bubbles.

 It is advisable to install an additional pressure pump in the circulation circuit between the expansion tank and the discharge section.

The properties of PFOS are widely known, consisting in an abnormally high ability to dissolve gases, as a result of which these compounds are used as highly effective gas-transporting media, for example, for blood substitutes, which are known to be used, in particular, for absorption of gases, for example, СО ₂ from liquid media, with whom they come in contact (Chemical Encyclopedic Dictionary, M. Soviet Encyclopedia, 1983, p. 435). In addition, PFOS are non-toxic, harmless, do not accumulate in living organisms, do not mix with water and have a high density of 1.8 g / cm ³ .

 The drawing shows a device for long-term maintenance and transportation of aquatic organisms.

 The device consists of a container 1 for organisms with an inclined bottom and a closed circulation circuit connected to system 2 for supplying liquid PFOS to it.

 The circulation circuit contains a pump 3 for taking PFOS from container 1, an oxygen saturation device 4, a filter for cleaning PFOS 5, an expansion tank 6 and a pump 7 for supplying PFOS to container 1, a flow regulator 8, a drain tank 9 and pipelines connecting them to the shutoff vents 10, 11, 12, 13, 14, 15, 16, 17.

 The discharge and suction sections of pipelines 18, 19 introduced into the container 1 and equipped with a spray 20 and a intake 21 PFOS.

 The pumps are driven by an electric motor.

 If the fish is transported in an airtight container 1, it is pre-checked for leaks, the pipelines, joints and the operability of the electric motor and pumps 3, 7 are checked by known methods.

 If the fish is transported or kept in an unpressurized container, then simply check the tightness of the piping connections and the operability of the electric motor and pumps 3, 7.

 The operation of the device is as follows.

 The container 1 is filled with water. With valves 10, 11, the electric motor turned on, with closed fans 12, 15 from system 2, it is fed into the PFOS circulation circuit, which, having left the system 2 with the help of pump 7, is supplied through container 1 to the discharge section of pipeline 18 and sprayer 20. Moreover, the sprayer can be of any type and provide the supply of PFOS under the surface of the water of the container or under its level. Since the density of PFOS is greater than the density of water, PFOS is collected in the intake 21, the filling of which is also fixed by any known method. When filling the intake 21, the vents 15, 16 open with the 13, 14 and 8 closed, and fish or aquatic organisms are loaded into 1. In this case, PFOS using pump 3 through the suction section of the pipeline 19 through the filter and oxygen saturation device 4 is supplied to 6. At the same time, when passing 4, the fan 17 is opened and for supplying oxygen or air to the circulation circuit of 6 PFOS, freed from free gas bubbles, saturated with oxygen by pump 7 is supplied 18 each to atomizer 20, where it is crushed and falls into water in the form of drops, where oxygen-rich PFOS, according to the laws of diffusion, gives off oxygen and takes carbon dioxide and other harmful substances from the water as well, which are products of fish life.

After passing through a layer of water with aquatic organisms located in container 1, drops or particles of PFOS under the influence of gravity are deposited on the bottom of container 1 and collected in intake 21. Then PFOS, depleted in O ₂ and saturated with fish vital products, from 21 to 19 using a pump 3 is run through a filter 5, where it is cleaned of mechanical impurities and through an oxygen saturation device 4, where it is saturated with oxygen and ends up in 6, where gaseous waste products are separated in the form of bubbles and so on.

 If during the operation of the system there is a decrease or increase in the level of PFOS, at 21, using regulator 8, the rate of intake of PFOS from 21 is regulated.

 After the fish has been delivered to the place or the required exposure time has been reached, it is unloaded, open 12, 13, and 11 are closed, when leaving the 21 layers of PFOS, the vents 15, 16, 17 are closed. When all PFOS is drained into 9, the vent 13 is closed and the pumps are turned off.

 This device for the maintenance and transportation of aquatic organisms allows you to provide them with oxygen while reducing energy consumption for circulation by 80-90% to minimize oxygen loss. Provide exposure or transportation of fish and aquatic organisms at planting densities several times higher than standard planting densities.

 In the case of using an unpressurized container from the composition of the closed circulation loop without violating the procedure, the expansion tank 6 and the feed pump PFOS 7 can be excluded. In this case, the oxygen saturation device 4 is directly connected to the fan 11.
