Problems solved by technology

After the water is used by the incubator, it is directly discharged through the filter. The water consumption is relatively large. Because the hatching water has high water quality requirements, the existing natural water of rivers and lakes is seriously polluted and cannot be used. At present, most of the hatching water is taken from groundwater. After being dried in the drying pool, it is then lifted to the high-level reservoir by the filter machine and enters the hatching equipment. During this process, the water is lifted in two stages, which consumes a lot of power
[0004] The existing hatching structure, whether it is the hatching tank or the hatching ring, has the disadvantages of bulky structure, cumbersome installation and operation, etc. What is important is that it directly uses the water flow as the power to drive the fertilized eggs, which requires relatively high water velocity
In addition, the development of fertilized eggs also requires high dissolved oxygen. Therefore, a large amount of fresh, high-dissolved oxygen hatching water is required. , consumes a lot of power

Embodiment Construction

[0018] Such as figure 1 As shown, the spawning pond and hatching site for fry hatching should be selected near the water source, near the broodstock pond, and near the drying water filter pond, and the water supply and drainage are convenient. The drying pool 2 is built on the leeward and sunny place, near the hatching site, with an area of ​​5--10 mu, 1.5-1.8 meters deep, and 5000-12000 cubic meters of water storage. Two 3-kilowatt impeller aerators are established in the pool; One side of the drying pool 2 near the hatching site is reserved for construction of a filter pool site. The filter pool 3 is built on one side of the drying pool 2, close to the hatching site; the filter pool 2 is a rectangular pool, the side connected to the drying pool 2 is built with a filter wall, and the other three sides are cement walls with a solid brick-concrete structure, and the material of the filter layer is made of stones. , coarse sand, fine sand, and medical stone; the water tower 5 i...

Abstract

An energy- and water-saving fish fry incubating system based on the combination of aerodynamics with fluid mechanics is composed of water well, water sunning pool, filter pool, water tower, drainage canal, fish fry collecting pool, incubator, deposition pool, adsorption pool, aerating pool, and water returning canal. It can save water by 60% or more and electric energy by 50% or more.

Description

[0001] Application field [0002] The invention relates to a fry hatching system for seed artificial breeding applied in the field of freshwater aquaculture, in particular to an energy-saving and water-saving fry hatching system. Background technique [0003] The current fish fry breeding system is mainly equipped with hatching rings and hatching tanks. Its working principle is to flush the fertilized eggs in the incubator evenly with the help of water flow so that they do not sink to the bottom and suffocate. : The ring path is 18-22 cm / s, the hatching tank makes the eggs roll evenly without sedimentation, and the flow rate is proportional to the flow rate. After the water is used by the incubator, it is directly discharged through the filter. The water consumption is relatively large. Because the hatching water has high water quality requirements, the existing natural water of rivers and lakes is seriously polluted and cannot be used. At present, most of the hatching water i...
