Description

an aquaculture system

technical field

The utility model relates to the technical field of aquaculture technology and aquaculture equipment, in particular to an aquaculture system.

Background technique

At present, in the traditional pond breeding of aquatic animals, because the feces of aquatic animals, feed residues and other dirt are not separated in the water body, the water body is seriously polluted, resulting in frequent occurrence of aquatic animal diseases, and limiting the breeding density and production.

Fish farming in ponds with circulating tanks invented by Auburn University in the United States has been gradually introduced into my country in recent years and has been well developed. It is a relatively advanced farming model at present. The main method is to build a tank with a width of about 5 meters and a length of about 25 meters in the aquaculture pond for breeding. The aquaculture tank accounts for 2%-5% of the total aquaculture water area, and the rest of the water is used to purify the water body. The water in the tank flows, and the manure in the breeding tank is washed to the sedimentation ditch behind the tank for precipitation, and then the settled manure is discharged out of the pond through the sewage suction machine, so as to reduce the pollution of the manure to the water body and improve the breeding environment to improve the breeding quality. density. There are still many disadvantages in racetrack tank farming, such as: in order to flush the feces in the tank out of the tank, it is necessary to maintain a relatively fast water flow rate, which leads to excessive exercise of aquatic animals in the tank, high feed consumption, and slow growth; feces follow the water flow Fast flow, insufficient short-distance sedimentation leads to only a small part of the feces can be pumped out of the aquaculture pond, and the pollution of the aquaculture water body is still relatively large. Currently, the amount of sewage collected is generally between 20% and 30%. In order to maintain a faster water flow, the power consumption is relatively low. Large; because aquatic animals have the habit of top water, the water inlet is too narrow, so that a large number of aquatic animals are crowded in the 5-meter-wide water inlet for a long time, squeezed and injured, and affect growth; the wastewater from the breeding tank flows to the tail, and the wastewater from the breeding animals is used to search for oxygen content The high new water intake leads to low utilization of the water area behind the tank; the bottom of the breeding tank and the manure sedimentation ditch needs to be dried and hardened after the construction cost is high.

Detailed ways

As shown in Fig. 1, the utility model is a kind of aquaculture system, and this aquaculture system mainly comprises pond 1 and is arranged on the cultivation bucket 3 in the pond, sedimentation ditch 4 and buffer pond 2, is also provided with water guide wall 5 in the pond , the water guide wall guides the water flow in a circular flow in the pond to increase the moving distance of the water, so that the water can be fully purified again and the dissolved oxygen in the water body can be increased. The sedimentation ditch 4 communicates the culture bucket 3 with the buffer tank 1 . The breeding bucket, sedimentation ditch and buffer tank in the pond adopt soft waterproof materials such as tarpaulins, and reinforcement support rods are arranged on the cultivation bucket, sedimentation ditch and buffer tank, and buoys 8 are arranged on the reinforcement support rods, and the buoys have multiple , respectively arranged at the edge of the breeding bucket, sedimentation ditch and buffer pool, so that the breeding bucket, sedimentation ditch and buffer tank are suspended in the water and the mouth exceeds the water level. The rod can be a horizontal fixed rod 9 or a straight fixed rod 19. The other end of the horizontal fixed rod 9 is hingedly connected with the pond inner wall to prevent the cultivation bucket, sedimentation ditch and buffer tank from floating and shifting and can float up and down. The vertical fixed rod 19 is perpendicular to the bottom of the pond, and the breeding bucket, sedimentation ditch and buffer tank are socketed with the vertical fixing rod through the fixing ring 18. The vertical fixing rod can prevent the breeding bucket, sedimentation ditch and buffer tank from shifting and shaking, and can also float up and down .

Wherein, the breeding bucket 3 is circular, square, rectangular, polygonal or other shapes, and the breeding bucket is provided with a water inlet tube 6, which is made of a soft flexible material. 3 on each side of the bucket wall, the water inlet of the water inlet tube 3 is arranged in the middle part of the culture bucket wall, and the water outlet of the water inlet tube is connected with a floating ball 7 by a stay rope, and each water inlet tube is on the side of the culture bucket on each side. The installation direction on the bucket wall is consistent. Since the inlet of the water inlet is in the middle of the water level, it can better adapt to the change of the water level, and the temperature of the water entering the breeding bucket is relatively stable. The outlet of the water inlet is maintained under the action of the floating ball and the rope. In the upper layer of the water body, but lower than the water level, the newly entered water replaces the aquaculture wastewater from top to bottom, so that the water in the aquaculture bucket forms a swirling flow, and the utilization rate of the aquaculture water surface is improved. The water inlet cylinder has scalability. When the water inlet cylinder is stretched to pull the outlet of the water inlet cylinder above the water surface, water can be prevented from entering the breeding bucket, which is convenient for feeding, medicating and catching the breeding animals. The bottom of the breeding bucket 3 is connected with the sedimentation ditch 4 through the sewage pipe 17. Under the action of the water pump 16, the breeding waste water and excrement after the aquatic animals are used are discharged from the breeding bucket through the sewage pipe 17 and enter the sedimentation ditch 4. The sedimentation ditch is upside down. Trapezoidal, on the top of the sedimentation ditch, a slide rail 11 is provided along the length direction of the sedimentation ditch, and a sewage suction device 12 for the sedimentation ditch is installed on the slide rail, and the sewage suction device moves along the length direction of the sedimentation ditch on the slide rail. After the waste water settles for a long distance in the sedimentation ditch, most of the manure sinks to the bottom, and is pumped out of the ditch through the orbital sewage suction machine, and the extracted manure can be reused as fertilizer for planting plants. Set overflow outlet 14 at the afterbody of sedimentation ditch, overflow outlet is positioned at the afterbody of sedimentation ditch and at the upper mouth position, only the water above can overflow, and can effectively avoid the excrement settled in the bottom layer to be taken out of sedimentation ditch when overflowing. The water after the primary purification in the sedimentation ditch overflows from the overflow into the buffer tank for secondary purification, and is discharged into the pond by the drainage pump 15 for three purifications and recycling. The drainage pump makes the water in the pond flow and circulate according to the path of "pond → breeding bucket → sedimentation ditch → buffer pond → pond". The buffer pool can not only purify the water body, but also buffer the time when the overflow of the sedimentation ditch enters, providing conditions for the use of other unstable energy sources such as wind pumps to drain water. Low, the water in the sedimentation ditch can continue to overflow, and the drainage pump automatically stops running to realize interval work to reduce power consumption and prolong the life of the pump. When the water level of the buffer pool rises to a certain height, the drainage pump starts to drain water again. The outlet of the sewage pipe in the sedimentation ditch is provided with a water pump, which can partially or completely pump out the water in the breeding bucket when using medicine or fishing.

Finally, an oxygen-increasing pipe 13 is provided at the bottom of the breeding hopper to increase the dissolved oxygen of the breeding water body and provide sufficient dissolved oxygen conditions for high-density farming. The rim of the bucket is also provided with a fence 10 to prevent aquatic animals from escaping from the breeding bucket.
