Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture equipment, and in particular to a nanobubble aerator. Background Technology
[0002] The most important thing in aquaculture is to maintain a certain oxygen supply in the water. Many aquatic mortality events are caused by insufficient oxygen supply. Maintaining sufficient oxygen supply in the water also helps the growth of aquatic animals and changes in their meat quality. Therefore, the water bodies suitable for aquaculture should meet the following requirements: 1. The water body has a certain degree of flow to maintain stable water quality; 2. It has a certain dissolved oxygen coefficient; 3. The water temperature is generally uniform.
[0003] Currently, common aeration equipment for aquaculture uses aerators to mix oxygen and water to form micro- and nano-bubbles, which are then discharged into the aquaculture pond. However, most current aerators use a water pump to pump water and oxygen into a mixer, where water or other structures within the mixer break down the oxygen into bubbles, which are then mixed with water to form bubble water before being discharged into the aquaculture pond. However, current aerators do not produce micro- and nano-bubbles with a high degree of bubble refinement, resulting in poor integration between the bubbles and water.
[0004] The technical problem to be solved by this application is: to design a nanobubble oxygenator that can improve the fineness of bubbles. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1: Please refer to Figure 1-2This utility model provides a technical solution: a nanobubble oxygenator, including a water pump 1 and an air supply pipe connected to the water pump 1. One end of the water pump 1 is provided with a gas-liquid mixing device connected thereto. A connecting pipe 5 is provided at one end of the water pump 1, and the water pump 1 is connected to the gas-liquid mixing device through the connecting pipe 5. The gas-liquid mixing device includes a gas dissolving device 2 and a first bubble refining mechanism 3 disposed within the gas dissolving device 2. A second bubble refining mechanism 4 is also provided at one end of the gas dissolving device 2. The gas dissolving device 2 includes a first gas dissolving pipe 20 and a second gas dissolving pipe 21 connected to the first gas dissolving pipe 20. The two ends of the connecting pipe 5 are respectively connected to the first gas dissolving pipe 20 and the outlet end of the water pump 1. An intermediate pipe 6 is provided between the connecting pipe 5 and the first gas dissolving pipe 20. The gas dissolving mechanism 3 includes an injection pipe 30 located between the intermediate pipe 6 and the first dissolved gas pipe 20. There is one or more injection pipes 30, each a Venturi nozzle. The injection pipe 30 serves to connect the intermediate pipe 6 and the first dissolved gas pipe 20. The injection pipe 30 has an internal bubble refining channel 301. The diameter of the bubble refining channel 301 is smaller than the diameters at both ends of the injection pipe 30, effectively giving the internal shape of the injection pipe 30 an hourglass shape. When the water pump 1 pumps oxygen gas and water together, as the gas and water flow through the bubble refining channel 301 within the injection pipe 30, the continuous pressure from the water pump 1 causes the diameter of the bubble refining channel 301 to decrease, resulting in increased pressure on the gas and water and a faster water flow rate. The gas is compressed and sheared, causing it to break into numerous small bubbles. These small bubbles, along with water, are then discharged into the first dissolved gas tube 20. Within the first dissolved gas tube 20, the bubbles and water fuse to form bubble water. The first bubble refining mechanism 3 further includes a first vortex tube 31 and a first cavitation tube 32 located between the first dissolved gas tube 20 and the second dissolved gas tube 21. One end of the first vortex tube 31 and the first cavitation tube 32 are connected. The first vortex tube 31 is installed inside the first dissolved gas tube 20, while the other end of the first cavitation tube 32 extends into the second dissolved gas tube 21. Essentially, the first cavitation tube 32 connects the first dissolved gas tube 20 and the second dissolved gas tube 21 via the first vortex tube 31. The first vortex tube 31 is located away from the first cavitation tube. One end of 32 is provided with a vortex rotor blade, and the interior of the first vortex tube 31 forms a first vortex chamber 310. When the bubbles and water ejected from the jet pipe 30 are in the first dissolved air tube 20, the bubbles and water will fully merge in the first dissolved air tube 20 to form bubble water. However, due to the continuous pressure supply of the water pump 1, when the pressure in the first dissolved air tube 20 reaches a certain level, the bubble water in the first dissolved air tube 20 will flow into the first vortex tube 31. When the bubble water is pressurized and flows into the first vortex tube 31, the vortex rotor blade will also rotate, thereby generating a driving force to push the bubble water forward. When the vortex rotor blade rotates, it will also generate a shearing force on the bubble water, thereby further refining the bubble water and obtaining bubble water with a smaller volume.
[0022] When the bubble water flows into the first vortex chamber 310, it then flows into the first cavitation tube 32. The first cavitation tube 32 is provided with several cavitation sections 320, and the entire first cavitation tube 32 is composed of several cavitation sections 320 connected together. Each cavitation section 320 has a through hole 321 in the middle, and a cavitation chamber 322 is formed between two adjacent cavitation sections 320. The diameter of the through hole 321 is smaller than the diameter of the cavitation chamber 322. When the bubble water flows through the through hole 321 in the first cavitation tube 32, the diameter of the through hole 321 becomes smaller. This is equivalent to the bubble water flowing from the low-pressure area of the cavitation chamber 322 to the high-pressure area of the through hole 321. At this time, the small bubbles in the bubble water will quickly collapse, thereby releasing energy and becoming even smaller micro-nano bubbles, thereby further increasing the fusion degree of oxygen and water and increasing the oxygen content in the water.
[0023] The second bubble refining mechanism 4 is connected to the outlet end of the second dissolved air pipe 21. The second bubble refining mechanism 4 includes a second vortex pipe 40 and a second cavitation pipe 41 connected to the second vortex pipe 40. The second vortex pipe 40 has the same structure as the first vortex pipe 31, and the second cavitation pipe 41 has the same structure as the first cavitation pipe 32. After the bubble water is refined by the first bubble refining mechanism 3, it is then discharged into the second dissolved air pipe 21 by the first cavitation pipe 32. With the continuous pressure and water supply from the water pump 1, the micro-nano particles in the second dissolved air pipe 21 are further refined. The sparkling water is discharged through the second bubble refining mechanism 4. Since the second vortex tube 40 and the second cavitation tube 41 in the second bubble refining mechanism 4 are structurally identical to the first vortex tube 31 and the first cavitation tube 32 in the first bubble refining mechanism 3, when the second bubble refining mechanism 4 discharges the micro-nano bubble water from the second dissolved air tube 21, the second vortex tube 40 and the second cavitation tube 41 in the second bubble refining mechanism 4 will further refine the bubble water, thereby forming micro-nano bubble water with a smaller volume and higher oxygen content.
[0024] Example 2: Please refer to Figure 3This utility model provides another technical solution: a nanobubble oxygenator, including a water pump 1 and an air supply pipe connected to the water pump 1. The water pump 1 is equipped with a gas-liquid mixing device connected thereto. The gas-liquid mixing device includes a gas dissolving device 2 and a first bubble refining mechanism 3 disposed within the gas dissolving device 2. A second bubble refining mechanism 4 is provided at one end of the gas dissolving device 2. The gas dissolving device 2 includes a first gas dissolving pipe 20 and a second gas dissolving pipe 21 connected to the first gas dissolving pipe 20. A connecting device is provided between the water pump 1 and the first gas dissolving pipe 20. Connector 5, an intermediate pipe 6 is provided between the connecting pipe 5 and the first dissolved gas pipe 20. The first bubble refining mechanism 3 includes a first injection pipe group 33 located between the intermediate pipe 6 and the first dissolved gas pipe 20, and a second injection pipe group 34 located between the first dissolved gas pipe 20 and the second dissolved gas pipe 21. Both the first injection pipe group 33 and the second injection pipe group 34 include a plurality of injection pipes 30. The inside of each injection pipe 30 is provided with a bubble refining channel 301. The diameter of the bubble refining channel 301 is smaller than the diameter of the two ends of the injection pipe 30. The internal shape of the jet pipe 30 is equivalent to an hourglass shape. When the water pump 1 pumps oxygen gas and water together, as the gas and water flow through the bubble refining channel 301 inside the jet pipe 30, the aperture of the bubble refining channel 301 becomes smaller due to the continuous pressure supplied by the water pump 1. Therefore, the pressure on the gas and water increases as they flow through this channel, and the water flow rate increases, resulting in a squeezing and shearing force on the gas. This causes the gas to be divided into several small bubbles. Subsequently, the divided small bubbles and water are discharged together into the first dissolved gas pipe 20. In the first dissolved gas pipe 20, the bubbles and water can merge to form bubble water. Then, the bubble water in the first dissolved gas pipe 20 is discharged into the second dissolved gas pipe 21 through the jet pipe 30 in the second jet pipe group 34, thereby further cutting the bubble water before it is discharged into the second dissolved gas pipe 21. Finally, it is discharged through the second bubble refining mechanism 4. While being discharged through the second bubble refining mechanism, the bubble water can be further refined into even smaller micro-nano bubble water, thereby increasing the oxygen content in the water.
[0025] The working principle of this utility model is as follows: By providing a first bubble refining mechanism 3 in the dissolved air device 2 and a second bubble refining mechanism 4 at one end of the dissolved air device 2, when the water pump 1 pumps water and oxygen together to the gas-liquid mixing device, the first bubble refining mechanism 3 and the second bubble refining mechanism 4 can refine the oxygen, thereby forming micro-nano bubbles. This allows the oxygen and water to fully dissolve in the water at the nanoscale through physical means, thus forming micro-nano bubble water. Furthermore, by providing the first bubble refining mechanism 3 and the second bubble refining mechanism 4, the bubbles can be transformed from large bubbles to micro bubbles, and then to micro-nano bubbles. This allows the oxygen to dissolve between the water and the nano-scale bubbles. Through step-by-step refining, the degree of refinement of the bubble water can be greatly improved.
[0026] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
