In order to increase the dissolved oxygen in the water body for aquaculture or environmental protection, an aeration device is generally arranged in the water body. The existing aeration device generally comprises an air pump, an air pipe and an aeration stone or an aeration pipe containing micropores, and the principle is that air or oxygen is discharged from water through the aeration stone or the aeration pipe to form bubbles, and the bubbles are contacted with liquid to fuse the oxygen in the bubbles into the water. In order to increase the dissolved oxygen amount, the aeration bubble amount is generally increased, or the diameter of the bubbles is reduced to increase the dissolved oxygen efficiency. However, the straight distance from the bubble to the water surface after the bubble is formed is short, the retention time of the bubble in water after the bubble is formed is short, and oxygen in the bubble is difficult to be fully dissolved into the water. When a plurality of bubbles are concentrated in the liquid to form, the dissolved oxygen at the periphery of the bubbles is saturated, the oxygen is difficult to dissolve in the water, and after the dissolved oxygen concentration in the water is formed by diffusion, the oxygen in the bubbles can be dissolved continuously, so that most of air or pure oxygen introduced by an air pipe is discharged into the air, and the efficiency is extremely low.

Meanwhile, all technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.

Referring to fig. 1 to 3, a device for improving an oxygen dissolving effect includes a bubble generator 100 and a bubble temporary storage mechanism 200, the bubble generator 100 and the bubble temporary storage mechanism 200 can be communicated with each other through a communicating pipe 300, the bubble generator 100 includes an air outlet, the bubble temporary storage mechanism 200 includes a straight tubular pipe body 210, the pipe body 210 includes a cavity, a baffle 220 is disposed at the rear end of the pipe body 210, the top end of the baffle 220 is fixedly connected with a pipe wall 211 of the pipe body 210, a bubble overflow outlet 230 is formed between the lower end of the baffle 220 and the pipe wall 211, and a bubble inlet 240 is disposed at the front end of the pipe body 210. At least part of the cavity is a bubble containing space 250, and a plurality of ventilation holes are arranged on the pipe wall 211 corresponding to the bubble containing space 250.

Further in a preferred embodiment, the tube wall 211 is a mesh structure.

In order to strengthen the dissolved oxygen effect of bubble, the utility model provides a bubble temporary storage mechanism 200 sleeps the bubble, forces the bubble to be detained in aquatic, forces the oxygen in the bubble to dissolve into aquatic as far as possible.

After the bubbles are formed in the bubble generator, the bubbles are discharged into the liquid and then enter the bubble-containing space 250 of the tube 210, and of course, the outer diameter of the bubbles is larger than the diameter of the ventilation holes of the tube 210. After the air bubbles are discharged into the water, the pressure of the air bubbles is the difference between the atmospheric pressure and the liquid level height of the liquid, the density of the air bubbles is hundreds times different from that of the liquid in the liquid, so that the buoyancy of the air bubbles is hundreds times of the weight of the air bubbles when the air bubbles are subjected to the liquid, and the density of the water at normal temperature is 1000 kilograms/m³The air density was 1.29kg/m at normal temperature and pressure³The buoyancy force F is (1000-1.29) g v, the viscous force F of water is μ dvxdy, and the bubble rising force F-F is obtained without external force. This is the bubble lift force during aeration in general. Therefore, the bubbles will be pressed against the inner wall of the tube 210 by the buoyancy, and since the baffle 220 is disposed at the rear end of the tube 210, the bubbles cannot move backward by the baffle 220, so that the bubbles are retained in the bubble-containing space 250. Since the bubble-containing space 250 includes the ventilation holes communicating with the outside, the oxygen in the bubbles is melted into the water body after passing through the ventilation holes. Under the diffusion of the concentration of dissolved oxygen, oxygen continues to dissolve into water.

The bubble generator 100 intermittently supplies bubbles into the bubble containing space 250, and the intermittent time is required to ensure that the prior bubbles can be sufficiently dissolved with the water body.

Because the pressure of the bubble generator is greater than the atmospheric pressure plus the liquid height difference pressure, when the subsequent bubble is separated from the bubble generator, the subsequent bubble receives the thrust of the internal gas of the bubble generator and is surrounded by the liquid, the volume is expanded, the pressure is reduced, the subsequent bubble can generate the thrust action on the previous stage bubble, under the action of the thrust action, under the acceleration of the subsequent stage bubble, the distance between the two bubbles is close, the liquid thickness between the bubbles is reduced, when the distance is close enough, the two bubbles can be fused due to the surface tension action of the liquid, in the process of fusion of the bubbles, the bubbles can impact the liquid, and the internal part of the liquid relatively moves; in addition, the movement of the bubbles on the tube body can also generate the movement of the bubbles, and the movement of the bubbles can also cause the relative movement of the interior of the liquid; the diffusion of dissolved oxygen is accelerated by the relative movement of the liquid interior.

The volume of the bubbles is continuously increased after the subsequent bubbles are fused with the previous bubbles, when the volume of the bubbles is continuously expanded, because the bubble overflow port 230 is arranged between the lower end of the baffle and the pipe wall, the overlarge bubbles can be discharged from the bubble overflow port 230, because the bubbles of the discharged part are generally bubbles which firstly enter the pipe body 210, the oxygen of the bubbles of the part is basically dissolved in the water body, and the bubbles of the discharged part can vertically rise in the water body and are discharged into the air because the bubbles are separated from the constraint of the pipe body 210.

Through increasing bubble temporary storage mechanism, make the bubble dwell time in aqueous long enough, make the oxygen in the bubble fully dissolve in aqueous, the bubble fuses and the exchange of space removal arousing liquid internal part molecule at the bubble removes and has promoted the mutual removal of liquid internal part molecule, improves dissolved oxygen efficiency.

In the second embodiment, referring to fig. 4, the tube 210 is not in a straight tube shape, and a raised part 260 protruding upwards is arranged in the middle of the tube 210, and the raised part 260 is communicated with the bubble containing space 250.

Unlike the first embodiment, in this embodiment, bubbles can be accumulated on the raised portion 260 by adding a raised portion 260 to the tube body. With this ridge 260, the baffle 220 structure may be omitted in some embodiments. Further, the maximum diameter of the bubbles in pipe 210 can be increased by ridge 260, and the oxygen dissolving efficiency can be further improved.

In a third embodiment, the bubble overflow outlet 230 may not be provided, and the tube body is made of a flexible material (such as a mesh material), one end of the tube body is fixed with the bubble generator, and the other end of the tube body is free. Because the bubble temporary storage mechanism is made of soft and light mesh cloth, one end of the bubble temporary storage mechanism is closed, the closed end is freely suspended, and gas can be sealed in the pipe body during work. Simultaneously, the gas inlet setting of this body is in the bottom and relatively fixed with bubble generator, and other parts are not fixed, and under the buoyancy of bubble effect, the software pipeline upwards floats, perhaps fixes at other parts of pipeline, forms multiple shape, increases bubble surface area and gaseous space that fills.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
