Description

Technical Field

[0001] The invention relates to the field of aquatic product transportation, and in particular to a parallel-type aquatic product transportation nanometer oxygenator. Background Art

[0002] When transporting aquatic products, they are often limited by the volume of the vehicle compartment. High-density packaging is often used. A relatively small space can hold more aquatic products. Conventional oxygen pumps have large bubbles that stay in the water for a short time and release quickly. The amount of oxygen that can be dissolved in the water is limited, and the crowded environment causes a large number of aquatic products to die of lack of oxygen.

[0003] Micro bubbles smaller than 50 microns will stay in the water for a long time. The diameter of the micro bubbles is small, so they can increase the contact area between gas and liquid and increase the oxygen content of gas in liquid, which is very beneficial for long-term aerobic respiration of aquatic products and can increase the amount of dissolved oxygen in the water (seawater) of aquatic products or fresh fish transport vehicles. To ensure the transportation of aquatic products, the supply of oxygen is required. The method of obtaining micro-nano bubbles in the prior art actually uses a water pump. In order to ensure a higher flow rate, the water pump used is relatively large, and the overall bubble generating device is relatively bulky, which undoubtedly limits the application of nano oxygenation in the transportation of aquatic products. Summary of the invention

[0004] Therefore, the present invention is made in view of the above problems. The purpose of the present invention is to provide a parallel aquatic transport nano-aerator, which is achieved through the following technical solutions:

[0045] The vertical pipe 101 is a tubular body disposed between the first output pipe 8 and the second output pipe 9, and a plurality of U-shaped pipe wall grooves 105 are vertically and spaced apart on the inner wall of the tubular body.

[0052] Working principle of the present invention:

[0053] ① Such as Figure 1 , Figure 2 , Figure 3As shown, the first gas-liquid mixing tube 4 and the second gas-liquid mixing tube 6 are placed in the aquatic box through a hose, and the first water pump 2 and the second water pump 3 are turned on. With the water path of the first gas-liquid mixing tube 4 as an array, the water flow is sucked into the first water pump 2. Since the first gas-liquid mixing tube 4 has a large front end 41, a small diameter reduction portion 42, and a larger rear end 43, under the suction of the first water pump 2, the diameter reduction portion 42 generates a high-speed water flow and generates a negative pressure near the first air pipe 5. External air is sucked into the first gas-liquid mixing tube 4. When flowing through the rear end 43, under the action of the circular reflection of the ring frame 46, reflected flows of different angles are formed, and collision, reflection, rotation, and mixing are formed between the mesh groove 44, the protrusion 45, and the ring frame 46, forming a preliminary gas-liquid mixture and refining the bubbles.

[0054] ② Similarly, the water channel of the second gas-liquid mixing pipe 6 completes the same processing process at the same time;

[0055] ③ Under the pressure of the first water pump 2 and the second water pump 3, the gas-liquid mixed water flow passes through the first output pipe 8 and the second output pipe 9, connected in a circular tangent manner and penetrates the interior of the vertical pipe 101. The incoming water flow forms a wall rotation in the same direction downward, and impacts the shaft groove 104 and the tube wall groove 105 at an inclined angle. This setting not only destroys the wall stagnation boundary layer and generates turbulence, causing part of the water flow to collide with the eaves of the shaft groove 104 and the tube wall groove 105, but also causes part of the water flow to enter the U-shaped groove to form a circumferential flow and turbulence, thereby further refining the bubbles of the gas-liquid mixture, and finally, under the gravity and the pressure of the first water pump 2 and the second water pump 3, it is discharged into the water in the aquatic box 100 through the release pipe 106, thereby increasing the oxygen content of the water in the aquatic box during aquatic transportation.
