Problems solved by technology

[0003] At present, the products I have artificially cultivated marine organisms in artificial seawater include "instant sea crystal", seawater, etc., which are all solid products mixed with salt directly adding some calcium and magnesium elements, and their chloride ion content is 55-60%. , due to the high content of chloride ions, the safety of use is low, and it is easy to cause chlorine poisoning of marine organisms, especially some fish and shrimp products with low chlorine discharge function are prone to poisoning and death, causing economic losses to farmers
Calcium and magnesium ions are important substances for the balance of electrolyte metabolism in marine organisms, and are important indicators for maintaining seawater osmotic pressure. Only when calcium and magnesium reach 3-4.7%, marine organisms can survive, grow and reproduce, and the survival rate is high. However, the content of calcium and magnesium ions in sea crystals currently on the market is lower than 2.6%, which cannot meet the needs of marine organisms, and can easily cause the death of marine organisms.
At the same time, because the existing products are all solid products, they are not easy to dissolve in water, and it is not easy to quickly mix evenly to cause uneven saltiness, making it difficult for marine organisms to absorb and adapt to the environment immediately
At the same time, using table salt as a raw material for production not only has high production costs (about 800-850 yuan / ton for table salt), but also is subject to the control of table salt monopoly policies, making it difficult to supply raw materials, which is not conducive to large-scale production and popularization and application

Embodiment 1

[0013] A high-pressure pump is used to filter out the impurities in the bitter brine through a filter cloth to obtain a clean bitter brine, and then the temperature is controlled at 60-90°C to concentrate the bitter brine to a Baume degree of 29-32. After cooling, put it into the mixing tank, add sodium chloride, calcium sulfate, sodium bicarbonate and oxidation in proportions of 38.5% of bittern, 59.195% of sodium chloride, 1.8% of calcium sulfate, 0.5% of sodium bicarbonate, and 0.005% of iron oxide. Iron and other elements can be mixed by the slurry pump.

[0014] After inspection, the chloride ion content in the liquid mixed sea water dew is less than 53%, while the calcium and magnesium ion content is 3-4.7%.

Embodiment 2

[0016] A high-pressure pump is used to filter out the impurities in the bitter brine through a filter cloth to obtain a clean bitter brine, and then the temperature is controlled at 60-90°C to concentrate the bitter brine to a Baume degree of 29-32. After cooling, put it into the mixing tank, add sodium chloride, calcium sulfate, sodium bicarbonate and oxidation in proportions of 80% bittern, 18.899% sodium chloride, 1% calcium sulfate, 0.1% sodium bicarbonate, and 0.001% iron oxide. Iron and other elements can be mixed by the slurry pump.

Embodiment 3

[0018] A high-pressure pump is used to filter out the impurities in the bitter brine through a filter cloth to obtain a clean bitter brine, and then the temperature is controlled at 60-90°C to concentrate the bitter brine to a Baume degree of 29-32. After cooling, put it into the mixing tank, add sodium chloride, calcium sulfate, sodium bicarbonate and iron oxide in proportions of 60% bittern, 38.297% sodium chloride, 1.4% calcium, 0.3% sodium bicarbonate, and 0.003% iron oxide. The other elements can be mixed by the slurry pump.

Abstract

The present invention discloses a liquid-crystal mixed sea-water concentrate which can be added in fresh water to obtain artificial sea-water for marine organism culture. Its composition includes (by wt%) 38.5-80% of bittern, 18.5-60% of sodium chloride, 1-1.8% of calcium sulfate, 0.1-0.5% of sodium carbonate and 0.001-0.005% of iron oxide.

Description

Technical field [0001] The invention relates to a liquid mixed sea water dew for artificial sea water. Background technique [0002] Marine life is only suitable for survival, growth and reproduction in the marine environment. Once it leaves the natural environment of the ocean, it cannot survive in fresh water. Because seawater contains the proper amount of chloride ions, calcium and magnesium ions and other elements and PH value for its survival, it is a necessary condition for the survival, growth and reproduction of marine organisms. [0003] At present, I have used artificial seawater to artificially cultivate marine life products such as "instant sea crystal", sea water, etc., which are solid products made by directly adding some calcium and magnesium elements with table salt, and the chloride ion content is 55-60% Because of the high content of chloride ions, the safety of use is low, and it is easy to cause chlorine poisoning of marine organisms. In particular, some fish a...
