Technical Field
The invention belongs to the technical field of aquaculture, relates to a filtering technology of a water inlet and outlet link in a freshwater shrimp culture process, and particularly relates to water inlet and outlet filtering equipment and a using method in freshwater shrimp culture.
Background
In aquaculture, water feeding and discharging and filtering are very important links, on one hand, enemy organisms can be prevented from entering a culture pond, and on the other hand, the cultured water cannot escape. The method is particularly important in the process of cultivating the improved freshwater shrimps, for example, the freshwater shrimps in the middle and lower reaches of the Yangtze river are all in the breeding period within 4-9 months, so that a large number of larvae or seedlings exist inside and outside the cultivation water body in the freshwater shrimp cultivation stage for a long time, and if water is not strictly filtered, the improved seedlings easily escape, varieties are mixed, and enemies enter, so that the cultivation benefit is seriously influenced. Because the young freshwater shrimps are very small, the mesh required by the filter screen is very small (80 meshes), and a common filter mesh bag is very easy to block.
Disclosure of Invention
The invention aims to provide a high-efficiency and reliable water filtering method for fine breed culture of freshwater shrimps aiming at the defects of the existing water filtering method in the freshwater shrimp culture process.
In order to achieve the purpose, the invention adopts the following technical scheme:
a high-efficiency and reliable water filtration method in the fine breed culture of freshwater shrimps is characterized in that: the water inlet and outlet are filtered by two overlapped net cages with different meshes in the freshwater shrimp culture process.
It is further characterized in that: when water enters, the meshes of the inner net cage are 40 meshes, the meshes of the outer net cage are 80 meshes, and the water inlet or the water outlet of the water pump allows the water entering the inner net cage to flow into the culture pond from the inner net cage to the outer net cage.
When water is drained, the mesh of the inner net cage is 80 meshes, the mesh of the outer net cage is 40 meshes, the edges of four edges and four corners of the bottom of the inner net cage and the outer net cage are all expanded by reinforcing steel bars, and the upper edge of the net cage is 30cm higher than the water surface; a shallow basin is arranged at the bottom of the inner net cage, a water suction head of a water pump or a water inlet of a drain pipe is arranged in the shallow basin, and water in the culture pond flows into the inner net cage through the outer net cage and is discharged through the water pump or the drain pipe.
Preferably, the outer net cage is larger than 2.0m × 2.0.0 m × 1.8.8 m, and the inner net cage is 1.8m × 1.8.8 m × 1.5.5 m.
The method filters the water for culturing the freshwater shrimps by the two overlapped net cages with different meshes, ensures the filtering quality and efficiency and prevents the good-breed shrimp seeds from escaping. Meanwhile, the filtering net cage is not easy to block and break.

Fig. 3 is a side view of the nested drainage of two net cages.
Detailed Description
The specific technical scheme of the invention is as follows:
as shown in fig. 1-3, the method is carried out by overlapping two large and small net cages and filtering with a double-layer net.
The size of the outer net cage 2 is larger than 2.0m × 2.0.0 m × 1.8m, the size of the inner net cage 1 is about 1.8m × 1.8.8 m × 1.5.5 m, and the net cage is made of high-quality nylon spun silk net.
As shown in figure 2, when water enters, the mesh of the inner net cage 1 is 40 meshes, the mesh of the outer net cage 2 is 80 meshes, and the water inlet 3 or the water outlet of the water pump allows the incoming water in the inner net cage 1 to flow into the culture pond from the inner net cage 1 to the outer net cage 2.
As shown in fig. 3, when draining, the inner net cage 1 mesh is required to be 80 meshes, the outer net cage 2 mesh is required to be 40 meshes, and the four edges and four corner edges at the bottom of the net cage are required to be unfolded by reinforcing steel bars. When water is drained, a shallow basin 4 is placed in the inner net cage 1, a water suction head 5 of a water pump or a water inlet of a drain pipe is placed in the shallow basin, and water in the culture pond flows into the inner net cage 1 through the outer net cage 2 and is drained through the water pump or the drain pipe.
Example 1:
when water is fed, the outer net cage is 2.1m × 2.0.0 m × 1.8.8 m and the meshes are 80 meshes, the inner net cage is 1.9m × 1.9.9 m × 1.5.5 m and the meshes are 40 meshes, and the water outlet of a water inlet pump is aligned with the water outlet of the inner net cage to enable the water to flow into the culture pond from the inner net cage to the outer net cage, when the water is discharged, the small net cage is 1.9m × 1.8 × 1.5m and the meshes are 80 meshes, the outer net cage is 2.1m × 2.0m × 1.8m and the meshes are 40 meshes, the four edges and the four corners of the bottom of the net cage are required to be unfolded by using steel bars, when the water is discharged, a shallow basin is arranged at the bottom of the inner net cage, a water suction head of the water pump is arranged in the shallow basin, the water in the culture pond, the water flows into the inner net cage through the outer net cage, and is discharged by the water pump.
Example 2:
when water is drained, an outer net cage is 2.1m × 2.0m × 1.8.8 m and 80 meshes of meshes, an inner net cage is 1.8m × 1.9.9 m × 1.6.6 m and 40 meshes of meshes, a water outlet of a water inlet pump is aligned with an inner net cage, and the water which enters the inner net cage flows into the culture pond from the inner net cage to the outer net cage, when the water is drained, the inner net cage is 1.9m × 1.8 × 1.5m and 80 meshes of meshes, the outer net cage is 2.1m × 2.1m × 1.8.8 m and 40 meshes of meshes, the net cages are required to be unfolded by using steel bar supports at four edges and four corners of the bottom, when the water is drained, a shallow basin is placed at the bottom of the inner net cage, a water suction head of the water pump is placed in the shallow basin, the water in the culture pond flows into the inner net cage through a large net cage, and is drained by the water pump.
