Fresh-keeping transport device for adult freshwater fish

Abstract

The invention belongs to the technical field of live fish transportation devices, and specifically relates to a fresh-keeping transportation device for adult freshwater fish. The opening direction of the air inlet box is opposite. There is a groove at the bottom of the inner side of the container. The bottom edge of the inner side of the container is inclined downward toward the direction of the groove. There is an auger in the groove. The free end of the connecting pipe is connected to the water inlet of the water pump, and the drainage is inverted U-shaped. The free ends of the tubes pass through the container above the insulation screen. Its purpose is: drive the container to move through the transport vehicle, use the wind generated by the container to increase the oxygen in the live fish in the container, and solve the problem of huge energy consumption caused by the long-term opening of the oxygen increasing equipment; at the same time, use the auger to The sediment produced during the transportation of adult fish is transported to reduce the residence time of sediment in the water body, improve the survival rate of adult fish, and make adult fish more fresh.

Description

technical field [0001] The invention belongs to the technical field of live fish transportation devices, and in particular relates to a fresh-keeping transportation device for adult freshwater fish. Background technique [0002] With the improvement of the quality of life, consumers have higher requirements for the freshness of aquatic products, so the market share of my country's aquatic products transportation continues to increase. Almost 100% of my country's freshwater fish meets domestic consumption (including Hong Kong, Macao, and Taiwan). Among my country's main agricultural products, meat, fish, eggs, and milk, the total output of aquatic products accounts for 31%, while the output of freshwater fish accounts for 10% of the total output of aquatic products. 30.3%, which plays a key role in the effective supply of aquatic products in the market. As people's demand for fish products tends to be fresh and alive, people pay more and more attention to the preservation and...

Problems solved by technology

[0005] Usually, the oxygenation method of the live fish container is to use air or oxygen inside the fish storage container to inflate the water body to increase oxygenation. Generally, live fish consume a lot of oxygen during long-term and high-density transportation, and a large amount of air or oxygen needs to be supplied. Once the live fish is put into the container, the oxygenation equipment must be turned on all the time to continuously increase the oxygenation of the live fish in the container, which consumes a lot of energy

[0006] At the same time, when the existing water circulation pipeline absorbs the sediment in the water body, it can only absorb the sediment at the inlet of the pipeline, and the sediment absorption efficiency is low, so that the sediment remains in the water body for a long time, causing pollution to the water body, making The survival rate of adult fish decreases, which in turn affects the freshness of adult fish
