A new type of low temperature tubular self-cleaning cage

Abstract

A new type of low-temperature tubular self-cleaning net cage, which relates to the technical field of special equipment for mariculture, includes a main body of the net cage and a booster pump, and a net is hung on the main body of the net cage, and the net is suitable for liquid nitrogen or liquid oxygen. The hollow conduit material for transmission is prepared, the hollow conduit material has a liquid inlet end and a liquid outlet end, one side of the liquid inlet end is connected with a liquid inlet pipe, and one side of the liquid outlet end is connected with a first The air outlet pipe, the liquid inlet pipe, and the first air outlet pipe are made of heat-insulating materials, and the booster pump has undergone cold insulation treatment. The other end of the liquid inlet pipe is connected to the liquid outlet of the booster pump, and the other end of the first air outlet pipe is One end is opened on the top of the main body of the cage, the liquid inlet of the booster pump is connected with a Dewar bottle of liquid nitrogen or liquid oxygen, and the top of the main body of the cage is also provided with a power supply device, and the booster pump and the power supply device electrical connection. The invention can quickly freeze fouling organisms through liquid nitrogen or liquid oxygen to achieve the purpose of net cage cleaning, is convenient to use, saves labor, and has good cleaning effect.

Description

technical field [0001] The invention relates to the technical field of special equipment for mariculture, in particular to a novel low-temperature tubular self-cleaning cage. Background technique [0002] Marine fouling organisms refer to marine organisms (including marine plants, marine animals and marine microorganisms) that adhere to, inhabit and grow on the bottom of ships, seawater pipelines, culture cages and other marine artificial facilities. Facilities can have serious impacts. According to the survey, there are more than 4,000 types of fouling organisms in the ocean, among which, the common marine fouling organisms include marine macroalgae, benthic algae, bivalves, barnacles, sea squirts, and sponges. A large number of fouling organisms attached to the nets will cause the nets of the cages to be clogged to varying degrees. On the one hand, the clogging of the nets will reduce the water exchange in the cages, make the breeding environment worse, and lead to freque...

Problems solved by technology

[0003] At present, traditional net cleaning methods mainly include manual cleaning, mechanical cleaning and drug cleaning. Among them, manual cleaning is a relatively primitive method of manually replacing net clothing, and the labor intensity of workers is relatively large; although mechanical cleaning It saves manpower, but in view of the sea environment where the offshore cage culture is located, the labor intensity of changing or cleaning the nets and the configuration of the net cleaning device are extremely high, that is, it takes a lot of material and financial resources; There may be certain hazards to organisms, and the release of drugs in the sea increases the possibility of water pollution

The above traditional net cleaning methods are difficult to meet the requirements of offshore cage culture management
