SU522838A1 - Plant for keeping and transporting live fish - Google Patents

Description

The invention relates to the field of transporting live fish to various distances by water, rail and other modes of transport.

A known installation for keeping and transporting a LI-YO fish, which includes a tank for fish, an aerating device, a device for thermally treating water, a device for cleaning SODE from suspensions, and a closed circulation circuit with a pump.

However, such an installation does not provide effective water purification from fish excretions (sludge, mucus, scum), and therefore the chemical and organoleptic characteristics of water, such as color, smell and iBiKyc, change, which leads to a reduction in the life of the trap. snortables fish.

In order to increase the lifespan of fish, the proposed plant is equipped with a cistern for a supply of pure water, connected to the circulation circuit by a pipeline with a valve for supplying seawater and an ozonizer, a circulation circuit between the aerating trio arrangement and the tank. At the same time, the device for cleaning 1 WATER of suspended matter is a sludge separator, and the device for heat treatment of water is equipped with a thermal relay. The tank for fish is equipped with a ratchet mounted above the bottom to form a cavity.

for the collection of contaminants, perforated tubes for supplying and Discharge of the outgoing water pipe and a pipe ejected into the bottom with an ejector for cleaning, while the upper wall of the tank is inclined and has a loading neck.

The drawing shows a schematic diagram of the proposed installation for the maintenance: And a live fish transport port.

The installation includes: 1 fish tank; aerating device 2; a device 3 for thermal water treatment, equipped with a thermal relay 4; a device for the purification of water from suspensions, which is a sludge separator 5; closed circulation circuit 6 with pump 7; tank 8 with clean water; a conduit 9 connected to the circulation circuit with a valve 10 for supplying seawater; an ozonizer 11 included in the circulation circuit between the aerating device and the container.

The tank 1 for fish is provided with a grille 12 mounted above the bottom to form a cavity 13 for collecting contaminants, and perforated tubes 14 and 15 for supplying and discharging water. In the bottom of the tank 1, a pipeline is mounted with ejectors 16 for cleaning. The upper wall 17 of the container 1 is inclined and has a loading opening 18 and a port 19 for venting. The water level in the tank 1 is controlled by the valve 20.

Inside the sludge separator 5 there are perforated guide plates (not shown), which change the direction of the water moving at low speed, as a result of which the notified particles are trapped and fall to the bottom of the smelter separator.

The aerating device 2 is a water-air ejector operated by a circulation circuit b. A closed circulation circuit with a valve 21-31.

Ozonizer I provides water disinfection and partial enrichment with oxygen due to its saturation with ozone (Oz) and its subsequent decomposition into Og and O.

To create a predetermined temperature regime of water serves as a refrigeration unit, 32.

An installation for keeping and transporting ipai6oTaeT fish is as follows.

Through the neck 18, the tank 1 is filled with water using any vessel means or a circulating pump. 7, for which the valves 21-27 are closed, and water is supplied from the side through the valve 10 (Kingston). Upon reaching a certain level of water in tank 1, live rya is loaded into it, the viability of which is provided by the operation of the installation either through an open circulation circuit, on a channel, while the vessel is at sea or in a bay (bay) with clean sea water (in bays and bays, the oil content is 3000 mg / l), or along a closed circulation loop when the vessel is moving in dangerous sea water, fresh water bodies, and ta | khe when being transported by another type of transport.

When working on an open circuit, on the duct, the valves 10, 20, 21, 27, 28, 29 and 30 are opened by starting the installation, the remaining valves are closed. The water from the valve 10 (Kingston) by the circulation pump 7 is supplied through the circulation circuit 6 iB to the perforated tube 14, and to drain the water from the tank 1 through the valve 20 is drained overboard. The valve 20 regulates the water level in the tank 1.

After the start-up of the installation, the following are included: sludge separator 5, for which the valve 23 is opened and the valve 27 is closed; aerating device 2, for which valve 25 opens and valve 29 closes; drinking water ozonizer 11 - opening the valve 29 and closing the valve 30; a device for heat treatment of water - closing the valve 28; refrigeration unit 32.

A solenoid valve 24 is then opened, and the operation of the refrigeration unit is controlled by means of a thermal switch 4.

Blowing the sludge separator 5 from sediments of slime and mucus is performed periodically, for which the valve 23 at its outlet is closed and the valve 31 opens, while

gaps are removed overboard or in any container. After cleaning, the sieve is again activated.

The removal of the slit from the cavity 13 is carried out with a partial pumping of water from the tank 1 by means of an ejector 16 driven by the fire-fighting system of the vessel (not shown).

When operating in a closed circulation circuit, the valves 21, 25, 27 and 30 open before the start of the circulation pump 7. Simultaneously with the start of the pump, the device 3 for thermally treating the water is turned on by turning on the refrigeration unit 32, due to which the salt screen valve 24 opens and the installation action 32 is controlled by a thermal switch 4. The water in the tank 1 is evenly distributed by the perforated tube 14. The water is drawn in from the tank 1 and circulated in the circuit continuously.

After the start-up of the installation, the following are included in series:

separator 5-opening valve 23 and incomplete opening valve 27; Drinking water ozonizer 11 - opening the valve 26 and closing the valve 30. The sludge separator is blown off as described above.

When seawater leaks or evaporates from tank 1, it is replenished from tank 8 by opening valve 22. Water from the tank is also used during transportation and storage of live fish in stores.
