Description

A water circulation system for adult fish breeding ponds

technical field

The utility model relates to the field of aquaculture, in particular to a water circulation system for fish breeding ponds.

Background technique

Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture includes extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as pond fish farming, cage fish farming and fence farming. High-density intensive farming uses methods such as running water, temperature control, oxygenation, and feeding high-quality bait to carry out high-density farming in small water bodies to obtain high yields, such as high-density fish and shrimp farming in running water.

In high-density intensive culture, the secondary water in the culture pond is not easy to recycle and utilize, resulting in a waste of water resources. the

Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model includes a high-level pool for replenishing water, a biological pool, an ultraviolet disinfection equipment, a water aeration machine, a culture pond, and a residual bait and feces collector connected by pipes from the sewage outlet of the culture pond. A sieve filter tank and a protein separator, the protein separator is connected with the water inlet of the biological pool by a pump body. In this example, commercially available biological pools are used, which are multiple settling tanks with hair brushes, commercially available water body aerators, which pass through the water body to inject oxygen into the water body, commercially available ultraviolet disinfection equipment, and commercially available water body aerators. protein skimmers for sale.

Described culture pond comprises the culture pond pond body of pot type, is located at the rotary sewage discharge device 11 that the bottom center of culture pond pond body is established, and described rotary sewage discharge device comprises the bottom of pot type sewage discharge device, is located at the backwater outlet at the bottom center of sewage discharge device and The sewage discharge port is located on the bottom side of the sewage discharger, the upper end of the return port is provided with a sewage discharger cover, the bottom of the residual bait and feces collector is conical, and the bottom of the conical shape is provided with a discharge port. There is a blockage on the mouth, a sewage pipe 10 is provided between the middle section of the residual bait feces collector and the sewage outlet, and an overflow pipe 13 is provided on the upper section of the residual bait feces collector. The overflow pipe connects the opening downward and the secondary The turning elbow 15 that the water purification filtering device is connected to.

Since the bottom of the aquaculture pond body is pot-shaped to facilitate the accumulation of dirt, the bottom of the pot-shaped sewage discharger of the rotary sewage discharger in the center of the bottom is equipped with a central return port and a spiral downward sewage discharge port on the side, which can effectively Separation of backwater and sewage. When the water swirls and flows in the breeding pond, it is conducive to the discharge of sewage. The upper end of the backwater outlet is equipped with a sewage discharge cover to prevent the aquaculture products from entering the sewage discharge outlet. After the sewage is discharged, the sediment is collected in the residual bait and feces collector. When the water surface 14 in the aquaculture pond rises, the upper layer clears and enters the overflow pipe with a turning elbow, and enters the secondary water purification and filtration link, which saves water sources, makes the purification and filtration effect better, and prevents the overflow from flowing back. Set up blowdown pool 12 under discharge outlet in this example.

A water return pipe connected to the water return port is inserted in the center of the drainer cover, and a water return hole is arranged on the upper circumference of the water return pipe. Effectively overcome the pressure difference at the bottom of the pool, so that the sewage can better enter the sewage outlet.

Described blockage is the columnar long plug 8 that is inserted in the discharge port, and described long plug is higher than residual bait feces collector. It is easy to pull out the blockage, and the operation is convenient.

The curved sieve filter pool includes an overflow tank 16 connected to the return pipe 22, a curved screen 18, a sewage collection tank 19 connected to the sewage pipe 20, and a curved sieve pool 21. The upper notch of the overflow tank is connected to the arc The upper end of the arc-shaped sieve is connected, and the lower end of the arc-shaped sieve is connected to the notch of the dirt collection tank.

Since it is installed on the curved screen, the screen surface is inclined, and the return water flows into the curved screen surface along the overflow tank, and the dirt is filtered and washed to the dirt collection tank at the lower end. The screen is not easy to store dirt in the mesh area, improving Dirt filtration efficiency.

The curved sieve is arranged along the length direction of the curved sieve filter tank, and reinforcing ribs 17 are arranged at intervals under the curved sieve. Strengthen the strength of the curved screen and improve the life of the curved screen.

Since the inflow disinfection and oxygenation process formed by ultraviolet disinfection equipment and water body aerator is set between the biological pool and the breeding pool, and the effluent filtration and purification process is formed by the residual bait feces collector, curved screen filter tank, and protein separator, Coupled with the purification function of the biological pool and the high-level pool for water replenishment, a complete set of circulation system is formed, which saves the use of water resources and ensures the growth environment of aquatic products.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these improvements and Retouching should also be regarded as the scope of protection of the present utility model.
