Problems solved by technology

[0002] During the transportation and storage of aquatic products such as fish and shrimp, the root cause of death is lack of oxygen. In order to solve the problem of aquatic products dying due to lack of oxygen, people have proposed mechanical oxygenation, sealed oxygenation and oxygenator oxygenation. Oxygenation transport method for living aquatic products, to a certain extent, solves the problem of death of aquatic products due to lack of oxygen during transportation and storage
[0003] At present, when transporting live aquatic products for a long distance or for a long time, most of the aquatic products are placed in a transport container. The existing transport containers for live aquatic products mainly Oxygen or replacement of water and other methods to replenish oxygen to the water in the tank in time, but because the solubility of oxygen in water is extremely low, using the above oxygenation methods to allow oxygen to automatically dissolve in the water will easily lead to low efficiency of dissolved oxygen and cannot be guaranteed for a long time The dissolved oxygen in water is not conducive to long-term transportation, thus reducing the survival rate of aquatic products

Embodiment 1

[0023] Such as figure 1 As shown, the box body 1 mainly includes an oxygen supply area 2 and a fish culture area 3, and the oxygen supply area 2 and the fish culture area 3 are separated by an inner partition 4, wherein the inner wall of the box body 1 is provided with a card slot, and the inner partition 4 is inserted into the draw-in slot, and the inner dividing plate 4 is a 0.4 mesh movable plate that can be freely disassembled. The oxygen supply area 2 is located on the side of the box body 1, and 15 hollow fibers 6 are laid in the oxygen supply area 2. The hollow fibers 6 are sealed and connected with the air inlet holes 5 on the side wall of the box body 1. One end of the hollow fiber penetrates into the air inlet 5 to connect with the external oxygen supply pipeline, and a fixed sealing device is arranged between the outer wall of the hollow fiber 6 and the air inlet 5 .

[0024] Such as figure 2 As shown, the fixed sealing device includes a hollow small sleeve 12 an...

Embodiment 2

[0031] With embodiment 1, its difference is: the hollow fiber 6 that lays in the oxygen supply area 2 is 30; The oxygen pipelines are connected, and the other end is sealed by gluing; the horizontal angle of the movable plate 14 is 20°.

[0032] A transport container with a volume of 8L is used to transport 50 juvenile light-colored croakers. According to the oxygen consumption rate of larval croakers, the oxygen consumption rate is 0.15-0.62mgO 2 / h·g fish weight, adjust the polyethersulfone hollow fiber laying density to be 320mm per liter of water body membrane surface area 2 , its pore diameter is 0.3 microns, the air supply pressure is 0.12atm (absolute pressure), the simulated transportation experiment is carried out, the transportation time is 56h, and the survival rate of the light-colored yellow croaker juveniles is above 95%.

Embodiment 3

[0034] With embodiment 1, its difference is: the hollow fiber 6 that lays in the oxygen supply area 2 is 100; The oxygen pipeline is connected, and the other end is connected with the air outlet pipe through a small hollow plastic sleeve; the horizontal angle of the movable plate 14 is 40°.

[0035] A transport container with a volume of 10L transports 20 yellow catfish, according to the oxygen consumption rate of the yellow catfish 0.20~0.87mgO 2 / h g fish weight, adjust the polyvinylidene fluoride hollow fiber membrane laying density per liter of water membrane surface area of ​​490mm 2 , its pore diameter is 0.4 micron, the air supply pressure is 0.13atm (absolute pressure), the simulated transportation experiment is carried out, the transportation time is 48h, and the survival rate of the yellow catfish is more than 93%.

[0036] The material of the hollow fiber can be polyethylene, polytetrafluoroethylene, polysulfone, polyvinyl chloride, polycarbonate, polyacrylonitrile...

Abstract

The invention discloses a membrane oxygenation type container for transporting aquatic living bodies, comprising a box body on which a sealing cover, a water inlet pipe and a water outlet pipe are arranged. The membrane oxygenation type container for transporting aquatic living body is characterized in that the box body mainly comprises an oxygen supplying area and a fish culturing area which areseparated from each other by a grid-like partition board, the oxygen supplying area is arranged on the side of the box body, at least one hollow fiber is laid in the oxygen supplying area, the wall of the hollow fiber is provided with micropores, one end of the hollow fiber penetrates through an air inlet hole so as to be connected with an outside oxygen supplying pipe, and a sealing device is fixed between the outer wall of the hollow fiber and the air inlet hole. Adopting the membrane oxygenation, the membrane oxygenation type container for transporting aquatic living body can realize the bubble-free oxygen supply, improve the oxygen dissolving efficiency, ensure the waterbody oxygen dissolving degree during the transportation of the aquatic living bodies and provide the environment suitable for the aquatic living bodies to live, thereby greatly improving the survival rate of the aquatic living bodies.
