Description

A circular body intensive aquaculture device

technical field

The utility model relates to aquaculture, in particular to an intensive aquaculture device with a circular body.

Background technique

Aquaculture is an important part of agricultural production. With the development of my country's economy and society, the scale of aquaculture continues to expand. Factory-intensive aquaculture has been widely popularized and applied due to its small footprint, low water consumption and high output. The high density puts forward higher requirements for its sewage system and breeding environment. In the actual breeding process, it is inconvenient to remove the feces and residual bait in the breeding pond. If not removed in time, the decomposed feces will directly affect the production of aquatic products.

At present, most of the sewage in factory-intensive aquaculture is removed by manual or mechanical filtration. Although it can be removed, it cannot be removed in a timely manner, resulting in some protein in the feces being dissolved in the water, causing certain pollution to the water quality. The cleaning equipment has complex structure, high energy consumption and high production cost.

It is inclined downward, and the included angle with the bottom of the sewage sedimentation chamber is 10-20 degrees. A sewage valve is fixed on the outside of the sewage pipe. The opening time is controlled manually or automatically. Using the water pressure in the breeding area and the inclined sewage pipe, open the sewage valve to remove the sewage. The sewage collected in the sewage sedimentation bin is discharged. The water inlet is set above the water level line. The water inlet pipe is fixed outside the water inlet. The angle between the water inlet pipe and the outer circle of the breeding area is 10-30 degrees. The water outlet is located below the water level line. A water outlet pipe is fixed outside the water outlet.

The lowest depression in the center of the cone in the lower part of the circular body culture area is 2-8% lower than the outer edge of the bottom of the cone.

The water outlet pipe is an L-shaped PCT pipe, which is high on the outside and low on the inside, and the outer pipe surface is consistent with the water level line. When the water in the breeding area exceeds the height of the water level line, the water automatically flows out through the water outlet pipe to control the water level in the breeding area.

In the utility model, the aquatic products are put into the circular body culture area, the height of the water surface is adjusted by the water outlet, and the height of the water level in the culture area is controlled. Put the flowing water through the water inlet and the water inlet pipe, and use its inclined angle and the momentum of the water to make the water in the circular body aquaculture area rotate along the water flow direction of the water inlet. The principle of specific gravity is greater than that of water, so that the feces, residual bait and other wastes produced in the aquaculture process are concentrated and vortexed and deposited in the depression at the bottom of the center of the circular aquaculture body. , to avoid water pollution caused by protein dissolving in water, and then through the control of the sewage valve, the sewage is discharged through the sewage pipe. At the same time, the water entering the circular aquaculture pond, and then the water higher than the water level control line is discharged through the water outlet, so that the water in the aquaculture area maintains continuous circulation, improves the dissolved oxygen performance and aquaculture effect in the aquaculture area, and increases aquatic products. production of aquaculture.

The utility model has a reasonable structure, the water in the culturing pond is driven and rotated by the impact force of the water in the water inlet, and the vortex is rapidly rotated in time to collect fish feces and dirt, and no other external power is used to achieve the rapid collection of feces and dirt, which is a kind of breeding density. High, effective, easy to use and low cost aquaculture device.

Compared with the prior art, the utility model has the following advantages:

1. The utility model utilizes the rotation of water in the circular body tank to generate vortex precipitation, quickly settles and collects fecal waste, has good sewage collection and discharge effect, solves the problem of difficulty in collecting feces and bait in intensive high-density culture, reduces the environmental pollution from farming

2. The utility model utilizes the continuous exchange and rotation of water, high dissolved oxygen and unit output, long-term growth of aquatic products in flowing water, low cost, high quality and good meat quality.

3. In order to ensure the continuous rotation and circulation of the water in the circular body culture area, the utility model can also set an adjustable water pusher in the culture area, according to the density of the aquatic products in the pool, by adjusting the speed of the water pusher, push the culture area. The inner water rotates to generate a vortex, which achieves the functions of vortex, sedimentation, fouling and oxygenation.

4. The structure of the utility model is scientific and reasonable, the construction cost is low, the use is simple, the energy consumption is low, the breeding cost is saved, and the production efficiency is improved.

5. The utility model can be built at one time, can be used for a long time, has no maintenance cost, long service life and low cost.
