Description

Airless Stone Breeding Container

technical field

The invention relates to a super-intensive aquaculture equipment, in particular to an airless stone culture container.

Background technique

In aquaculture, dissolved oxygen is an important factor affecting the food intake, growth rate, feed coefficient and health status of fish and shrimp. According to relevant data, the feed coefficient of fish when dissolved oxygen is 3 mg/L is greater than that when it is 4 ppm Double, the growth rate of fish grown in dissolved oxygen 7ppm is 20%-30% faster than that of fish grown in dissolved oxygen 4PPm, while the bait coefficient is 30%-50% lower. When the amount of dissolved oxygen in the water reaches above 4.spPm, the fish's appetite will be greatly enhanced. For this reason, my country's "Fishery Water Quality Standards" stipulates that the dissolved oxygen (DO) in aquaculture water must be kept at least 5mg/L for more than 16 hours in a 24-hour day, and should not be lower than 3mg/L at any time. Existing technologies such as China's invention patent application "Cross Plate Type Multifunctional Artificial Fish Reef", patent application number 201110070062.6, this invention discloses a liquid oxygen application synergistic device for industrial aquaculture, which utilizes the existing For the high-level pool and the water inlet pipeline, an artesian water pipe is added at the end of the liquid oxygen oxygenation terminal - the nano-disk. The end of the water pipe is hot-pressed into a duckbill shape, and the flow rate of the water is adjusted through the valve. The pure oxygen microbubble flow forms a gas-water mixing zone, and then the mixed flow of the two forms a circulation in the culture pond. This not only solves the phenomenon of oxygen escaping in the traditional liquid oxygen oxygenation method due to the static water state and the local oxygen supersaturation caused by the shallow water in the culture pond, but also solves the problem of unbalanced dissolved oxygen in the culture pond. The invention ensures the high dissolved oxygen state of all water bodies in the culture pond, so it can improve the feeding rate and digestibility of aquatic animals, increase the growth rate by 20%, and increase the output by 30%. However, the use of liquid oxygen requires regular replacement of the oxygen source, which is not convenient enough to use.
