Description

Technical Field

[0001] The utility model relates to the technical field of circulating water oxygenation devices, in particular to a circulating water oxygenation device for a fish pond. Background Art

[0002] Land-based recirculating aquaculture is based on land and adopts a "controlled shore-based recirculating aquaculture system". Its farming advantages are that the adult fish under this controlled system are pollution-free, have no earthy smell, taste good and have considerable sales. High-density farming of adult fish is achieved through breeding ponds, and the unit breeding density can reach 40 times that of traditional earth pond farming models. However, land-based recirculating aquaculture requires a large amount of oxygen, and the conventional method of adding source water is difficult to meet the oxygen supply demand.

[0003] In the existing land-based recirculating water aquaculture oxygenation devices, different sizes of breeding ponds require different oxygenation methods. Large breeding ponds can be installed with oxygen supply pipes of different sizes to directly introduce oxygen into the breeding water to increase the oxygen content, forming a flowing water body for adult fish to keep swimming. Small breeding ponds are smaller in size and have a higher density of adult fish in the ponds. The aeration and oxygenation pipe method easily causes adult fish to accumulate in the oxygen-rich area in the crowded breeding ponds. The smaller fish in the accumulated fish often cannot grab food, thereby affecting the overall growth efficiency of the fish. At the same time, the existing small breeding ponds rely on manual adjustment for sewage discharge. The water pipe before sewage discharge will continuously supply source water through the pump body, causing the water level in the breeding pond to continue to rise. When the electricity consumption is low, the pump body voltage increases the water supply, which easily leads to overflow of large amounts of adult fish. Utility Model Content

After pretreatment, it flows back into the breeding pond, effectively reducing the use of source water and reducing water use costs, while avoiding overflow caused by excessive water inflow into the breeding pond.

The output end is connected to the pressurized oxygen cone 53 for water-oxygen mixing. A swirl pipe 54 is provided at the bottom of the pressurized oxygen cone 53. A water outlet elbow 55 is provided at the water outlet of the swirl pipe 54. The water outlet elbow 55 is provided in the middle of the culture pond 1. The bottom of the culture pond 1 is a conical structure. After the water flow is pushed into the water outlet elbow 55 along the inner wall of the culture pond 1, a swirl is formed at the bottom of the culture pond 1. The feces and biomass of the adult fish accumulate at the bottom of the culture pond 1 under the action of the swirl and flow into the sewage collection tank 33 of the sewage collection and drainage component 3. The sewage is regularly extracted and cleaned by the timed sewage valve 42 of the sewage discharge component 4. The circulating oxygenation component 5 structure is used to circulate the aquaculture water. Oxygenation, the anti-escape flow pipe 34 in the sewage collection and water flow part extracts the aquaculture water from the middle of the aquaculture pond 1, and the aquaculture water flows into the upper part of the pressurized oxygen cone 53 and mixes with the pure oxygen introduced from the output end of the aerator 2 to increase the oxygen content in the aquaculture water. The oxygen content of the aquaculture water after aeration can reach 15 mg / L. The aquaculture water after aeration re-enters the aquaculture pond 1 through the vortex pipe 54 under high pressure, and is sprayed out in a direction parallel to the inner wall of the aquaculture pond 1 under the guidance of the outlet elbow 55, forming a rotating water flow inside. The highly oxygenated water circulates evenly in the aquaculture pond 1, effectively avoiding the accumulation of fish in the small aquaculture pond 1; the overflow filter provided by the sewage discharge component 4 The flow pipe 45 and the observation pipe 44 are connected to the water body in the breeding pond 1. The vertically arranged observation pipe 44 can synchronize with the internal water level while allowing the feces of adult fish and other impurities to settle in the second connecting pipe 41. When the voltage of the external water pump 52 that pushes in the source water increases, the breeding water level rises, and the water level in the observation pipe 44 rises synchronously. When the breeding water level is higher than the overflow pipe 45, it flows into the circulation pool 46 through the overflow pipe 45 and re-enters the source water treatment pool.

The staff can check the outflow of tailwater inside the sewage collecting tank 43 through the observation holes and conduct sampling inspection at the same time.

[0024] In this embodiment, the circulation pool 46 is rotatably connected to a cover plate and a connecting pipe connected to an external source water treatment pool. The connecting pipe is arranged at the bottom of the circulation pool 46. A plurality of inspection holes are formed in the middle of the cover plate. The inner wall of the circulation pool 46 is provided with a water level detection component for detecting the water level height. The water level detection component is used to detect the water level inside the circulation pool 46, realize water level warning, and remind staff to adjust the power of the water pump 52 to introduce source water in time, thereby saving the cost of source water use.

[0025] In this embodiment, an observation port 47 is formed at the upper portion of the observation tube 44, and a water level observation groove 48 is formed in the middle portion of the observation tube 44.

The anti-escape water pipe 34 inserted into the middle of the breeding pond 1 has multiple groups of anti-escape holes 35 on the upper part for extracting breeding water. The anti-escape hole 35 structure located at the upper part effectively prevents the suction of debris at the bottom of the pool into the oxygen cone, thereby ensuring the pressurized oxygenation effect of the breeding water.

[0028] The working principle of this utility model:

[0029] The anti-escape water pipe 34 in the sewage collection and water flow component draws aquaculture water from the middle of the culture pond 1. The aquaculture water flows into the upper part of the pressurized oxygen cone 53 and mixes with the pure oxygen introduced at the output end of the aerator 2 to increase the oxygen content in the aquaculture water. The oxygenated aquaculture water re-enters the culture pond 1 through the swirl pipe 54 under high pressure. Under the guidance of the outlet elbow 55, it is sprayed out in a direction parallel to the inner wall of the culture pond 1, forming a rotating water flow inside. Under the action of the swirl flow, the feces and biomass of the adult fish accumulate at the bottom of the culture pond 1 and flow into the sewage collection tank 33 of the sewage collection and drainage component 3. It is regularly pumped out and cleaned by the timed sewage valve 42 of the sewage discharge component 4.

[0030] The vertically arranged observation tube 44 can synchronize with the internal water level while allowing the feces of adult fish and other impurities to settle in the second connecting tube 41. When the voltage of the external water pump 52 that pushes in the source water increases, the aquaculture water level rises, and the water level in the observation tube 44 rises synchronously. When the aquaculture water level is higher than the overflow pipe 45, it flows into the circulation pool 46 through the overflow pipe 45 and re-enters the source water treatment pool. After pretreatment, it flows back into the aquaculture pond 1.

[0031] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
