Description

Technical Field

[0001] This utility model belongs to the field of aquaculture pond technology, and specifically relates to an oxygenation device for aquaculture ponds. Background Technology

[0002] In aquaculture, a healthy aquatic environment not only reduces the risk of large-scale mortality of farmed organisms but also saves feed and improves farming efficiency. Aquaculture ponds resemble artificial ecosystems. In practice, we have found that when the oxygen content in the water is insufficient, the decomposition of organic matter is restricted, the material and energy cycle is affected, and uneaten feed and feces ferment and deteriorate in the water, leading to increased concentrations of harmful substances such as ammonia nitrogen ions and nitrites in the pond water. This severely affects the resistance of farmed organisms and causes disease outbreaks. Therefore, developing an aeration device for aquaculture to avoid the aforementioned technical problems caused by insufficient water oxygen content is a direction that requires further research by those skilled in the art. Utility Model Content

[0003] The purpose of this utility model is to provide an aeration device for aquaculture ponds that can organically combine the acceleration of water circulation and aeration in the aquaculture pond, taking into account both the acceleration of water circulation and aeration while saving equipment energy consumption.

[0004] The technical solution provided by this utility model is an aeration device for aquaculture ponds, which includes:

[0005] A water pipe is provided with an outlet at one end and an inlet at the other end. The outlet is located above the inlet. A first sealing interface is also provided on the water pipe near the inlet.

[0006] An oxygenation pipe is provided at one end, which is configured to be connected to an oxygen pump; the other end of the oxygenation pipe extends into the body of the water pipe through the first sealing interface; and the oxygenation pipe is provided with an aeration pipe located inside the water pipe, the aeration pipe having air holes that communicate with the air inlet.

[0007] This technical solution involves installing a water pipe within the aquaculture pond, with the outlet positioned above the water surface and the inlet below. The pond water enters the water pipe through the inlet, submerging the aeration pipe. Simultaneously, the air inlet is positioned above the water surface and connected to an external oxygen pump. The external oxygen pump then pumps oxygen into the aeration pipe. This oxygen flows through vents into the water pipe, creating bubbles in the pond water. The water, bubbling under the influence of these bubbles, flows along the first straight pipe into the first bend, forming a current that is reintroduced into the aquaculture pond. This flow accelerates water circulation. During this process, some of the pumped oxygen dissolves into the pond water, thus oxygenating it. This oxygen flow accelerates water circulation, saving energy. The oxygen-rich water flow can also adsorb various particulate dirt and soluble organic matter in the aquaculture water, achieving an effect similar to a protein skimmer.

[0008] Preferably, the water pipe includes a first elbow, a first straight pipe, a first tapered connector, and a second straight pipe connected in sequence; the first straight pipe and the second straight pipe extend in a vertical direction, and the diameter of the second straight pipe is larger than the diameter of the first straight pipe; the outlet is located at one end of the first elbow; the inlet is located at one end of the second straight pipe; and the aeration pipe is located inside the body of the second straight pipe.

[0009] By adopting this technical solution, the water outlet is located at the first bend, allowing water to be sprayed obliquely into the aquaculture pond from the outlet, thus increasing the range of water circulation. The first straight pipe, the first conical connector, and the second straight pipe together form a Venturi tube structure, which accelerates the water flow formed during oxygen aeration, allowing the water to be sprayed further from the outlet.

[0010] Preferably, the aeration pipe includes a second elbow, a third straight pipe, a third elbow, and an internal pipe connected in sequence; the third straight pipe extends in a vertical direction; one end of the internal pipe is connected to the third elbow via the first sealing interface, and the other end is fixedly installed on the inner wall of the second straight pipe via a fixing joint; both ends of the aeration pipe are connected to the internal pipe respectively.

[0011] By adopting this technical solution, oxygen enters the aeration pipe sequentially through the second bend, the third straight pipe, the third bend, and the internal pipe, and forms an aeration effect inside the water pipe.

[0012] Preferably, the aeration pipe is an aeration nanotube flexible tube, and the aeration nanotube flexible tube has nanoscale pores distributed on it.

[0013] By adopting this technical solution, nano-sized pores form a large number of fine bubbles in the pool water inside the water pipe, thereby increasing the oxygenation efficiency.

[0014] Preferably, the built-in tube includes a first inner tube and a second inner tube that are parallel to each other; there are two aeration nanotubes, each aeration nanotube has an inverted U-shaped structure, and both ends of the tube body of each aeration nanotube are electrically connected to the first inner tube and the second inner tube respectively; and the middle sections of the tube bodies of the two aeration nanotubes are cross-connected.

[0015] By adopting this technical solution, the contact surface between the aeration pipe and the water body is increased, which increases the number of bubbles formed per unit time and improves the efficiency of aeration and oxygenation.

[0016] Preferably, the inner wall of the first elbow is provided with a removable sponge layer.

[0017] By adopting this technical solution, the sponge layer can play a certain role in filtering and purifying the pool water sprayed from the first bend.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] First, this invention can simultaneously accelerate water circulation and increase water oxygenation, thus saving equipment energy consumption.

[0020] Secondly, this invention can generate a large number of fine bubbles in the pool water, increasing the oxygenation efficiency.

[0021] Thirdly, this invention can adsorb various particulate dirt and soluble organic matter in aquaculture water, achieving an effect similar to a protein separator.

[0022] Finally, this invention has a simple structure and is easy to manufacture and use on a large scale. Attached Figure Description

[0031] The water pipe includes a first elbow 110, a first straight pipe 120, a first conical connector 130, and a second straight pipe 140.

A first sealing interface 231 is provided on the side wall of the second straight pipe 140. The diameter of the second straight pipe 140 is larger than the diameter of the first straight pipe 120. A removable sponge layer 112 is also distributed on the inner wall of the first elbow 110, and the sponge layer 112 has a centrally open tubular structure.

[0032] The oxygenation pipe includes a second elbow 210, a third straight pipe 220, a third elbow 230, an inner pipe, and the aeration pipe. The inner pipe further includes a main inner pipe 241, a first inner pipe 242, and a second inner pipe 243; one end of the second elbow 210 is provided with an air inlet 211, which is configured to be connected to an oxygen pump. The other end of the second elbow 210 is conductively connected to the upper end of the third straight pipe 220. The third straight pipe 220 extends vertically, and the lower end of the third straight pipe 220 is conductively connected to one end of the third elbow 230. The other end of the third elbow 230 extends into the interior of the water pipe through the first sealing interface 231 and is conductively connected to one end of the main inner pipe 241. The other end of the main inner pipe 241 is fixedly installed on the inner wall of the second straight pipe 140 through a fixing joint 244. The first inner pipe 242 and the second inner pipe 243 are parallel to each other and are conductively connected to the main inner pipe 241 respectively. The aeration pipe adopts an aeration nano-flexible hose 250, and the aeration nano-flexible hose 250 has nano-sized air pores distributed on it. There are two aeration nano-tubes 250, each with an inverted U-shaped structure.

The middle sections of the tube bodies of the two aeration nano-tubes 250 are cross-connected.

[0033] In practice, its working process is as follows:

[0034] A water supply pipe is installed in the aquaculture pond, with the outlet 111 positioned above the water surface and the inlet 141 positioned below the water surface. The pond water enters the water supply pipe through the inlet 141, submerging the aeration pipe. Simultaneously, the air inlet 211 is positioned above the water surface and connected to an external oxygen pump. The oxygen pump is then turned on, pumping oxygen into the aeration pipe. This oxygen flows through the air vent into the water supply pipe, creating gas bubbles in the pond water. Under the influence of these gas bubbles, the pond water flows along the first straight pipe 120 into the first bend 110, forming a water flow that is reintroduced into the aquaculture pond through the first bend 110. This water flow accelerates the water circulation in the aquaculture pond. During this process, some of the pumped oxygen dissolves into the pond water, thus oxygenating the aquaculture pond. This use of oxygen flow to accelerate water circulation saves equipment energy. The oxygen-rich water flow can also adsorb various particulate dirt and soluble organic matter in the aquaculture water, achieving an effect similar to a protein skimmer.
