Description

Cooling device in a kind of live fish transportation

Technical field

The utility model relates to and is specially adapted for live fish transport device.

Background technology

In the prior art, when people in summer during with a large amount of live fish of vehicle-mounted transportation, if Yunqi is no more than two days, people onboard fish box bottom put into ice cube, put dividing plate with holes then, put clear water and live fish again, the purpose of putting ice cube is in order to allow live fish live in lower water temperature, so that their metabolism becomes slower, the refuse of discharging still less, the cleannes retention time to water quality is also long as far as possible, also constantly sends into fresh air simultaneously in water, and this has just reduced the lethality of live fish.But, the device of this transport of living fish has following shortcoming: first, near above the fish box bottom baffles water temperature is very low, and about 2-3 ℃, if the live fish in the water temperature is placed in the so low water temperature more than 20 ℃ living in quickly, suddenly cooling can make the sashimi (raw fish) disease, the density of adding fish is very big, water and fish than about 1.2-1.3 than 1, the quality of living environment is bad again, therefore, the lethality of live fish can increase; The second, because very low from the near water temperature of ice cube, the temperature difference that forms between fish and the water is too big, the shoal of fish can absorb the colds in the water in a large number, impels the thawing speed of ice cube to increase, and keep the low temperature in the fish box in the delivery period, must put ice cube more, this has just increased vehicle-mounted weight, can reduce the quantity that betransported live fish, the 3rd relatively, if transportation is ocean fish, because the thawing of ice cube can water down the salt in the seawater, it is low more that seawater is watered down, also big more to the threat of ocean fish existence.

Summary of the invention

In order to overcome the shortcoming of prior art, the utility model provides the cooling device in a kind of live fish transportation, by improving the structure of vehicle-mounted transport of living fish device, to improve the quality of live fish living environment, reduces live fish lethality in transit.

Solution of the present utility model is as follows:

Cooling device in described a kind of live fish transportation, comprise fish box, diaphragm plate by a plurality of porous is divided into a plurality of spaces with fish box inside, the fish box cover plate of band pore, be located at the fish box inner bottom part a plurality of porous and connect air supply pipe, its air inlet links to each other with air feed pump, it is characterized in that: the fish box inner bottom part also be provided with a plurality of porous vertically and the water inlet pipe that connects, its water inlet is connected with the outlet of a plurality of and the vertically arranged snakelike heat-exchange tube that connects, the water inlet of heat-exchange tube is connected with the outlet pipe that is positioned at the higher position of fish box by water pump, pump outlet is provided with choke valve, heat-exchange tube is fixed in the heat exchanger body, the heat exchanger cover plate is located at heat exchanger top, and ice cube is placed on the inner chamber of heat exchanger body, injects clear water in the fish box.

Also can before the water inlet of water pump, one filter be set, so that filter out the excreta of fish in the fish box.

Can also be at fish box, the fish box cover plate, the outer surface of heat exchanger body and heat exchanger cover plate is provided with heat-insulation layer, to prevent scattering and disappearing of cold.

Can find out from above-mentioned solution: when summer during with vehicle-mounted transport of living fish, because the cold that provides in fish box is to obtain by the heat exchanger that the current in the fish box are made cooling medium via ice, these colds by be located at a plurality of porous below the fish box vertically and the water inlet pipe that connects deliver to each position of fish box uniformly, live fish in the fish box can both obtain cold uniformly, again owing to can water and fish in the fish box slowly be lowered the temperature by operation water pump and choke valve, until the temperature that drops to hope, so live fish can not be subjected to the threat of cooling suddenly, sick possibility also can significantly reduce, also can find out from above-mentioned solution, because ice cube and live fish are not to be in the same space, during especially to vehicle-mounted transportation ocean fish, can not reduce the salt content of seawater owing to the thawing of ice cube, the physiological needs of ocean fish have been guaranteed, reduced the lethality of ocean fish, in addition, when being provided with cleaner before the water inlet of water pump, can in time discharge the excreta of live fish, thereby the cleannes that kept water quality, reduced growing of pest and noxious bacteria, this will further reduce the lethality that betransported live fish.
