[0032] Reference Figure 1 and Figure 2 The embodiment provides a gas lift filtration oxygenation device, which comprises a main body 1 and a filter assembly 6.

[0033] The main body 1 is a tubular structure with a fluid passage in the inside, the lower part is closed, and the upper part is open. The air inlet 2 is arranged on the side surface of the lower part of the main body 1 close to the bottom, which is outwardly extended and upwardly bent to form a sharp head tubular structure, so as to be connected with the air pipe 14 arranged from top to bottom, thereby avoiding the influence of the air pipe 14 on gas delivery due to bending. The water inlet 3 is arranged on the other side surface above the air inlet 2, which is a tubular structure outwardly extended and downwardly bent, so as to not only facilitate the absorption of impurities deposited on the bottom of the container, but also improve the filtration effect by using the water pressure difference. The air inlet 2 and the water inlet 3 are in communication with the fluid passage in the inside of the main body 1.

[0034] The filter assembly 6 is a cylinder with a space for containing filter material 11 in the inside, the bottom of which is provided with a bottom surface, the middle of the bottom surface is provided with a communication port 8, and a plurality of discharge ports 10 are arranged around the communication port 8. The discharge port 10 is provided with a circular filter cotton filter material 11 with a middle opening above it. The filter material 11 is installed in the space of the filter assembly 6 and is sleeved on the main body 1 during use.

[0035] In addition, the filter assembly 6 is also provided with a top cover 9, which is a cylindrical cover body. The lower end of the top cover 9 is combined with the upper end of the filter assembly 6 through a matched thread fastening structure 7, so as to facilitate the opening of the space of the filter assembly 6 for cleaning or replacing the filter material 11. The communication port 8 at the bottom of the filter assembly 6 is sleeved on the lower extension part of the outer upper part of the main body 1 and is fixed by adhesion. A part of the upper part of the main body 1 passes through the communication port 8 and enters the space of the filter assembly 6, so as to form a filter water space with sufficient depth.

[0036] The bottom of the main body 1 is also provided with a fixing assembly 5, which is a heavy circular stone disc. The main body 1 is vertically arranged in the middle of the fixing assembly 5 and is fixed on the fixing assembly 5 by bonding, so that the main body 1 can be stably placed at a specific position in the water container 12 by weight.

[0037] The water container 12 is a circular fish tank with an opening at the upper part and filled with water. The lower part of the main body 1 is placed at the bottom of the water in the fish tank, and the filter assembly 6 at the upper part of the main body 1 is located above the water surface of the water container 12. The air inlet 2 of the main body 1 is conveniently connected with the air pipe 14 through a pointed tubular structure, and the air pipe 14 is connected with the air pump 13 outside the water container 12.

[0038] The device utilizes the synergistic effect of water pressure difference, air pump 13 thrust and gas buoyancy to automatically make the water enter the fluid channel in the main body 1 through the water inlet 3. The air pump 13 thrust delivers the gas to the air inlet 2 of the main body 1 and into the fluid channel of the main body 1 to form an upward bubble flow. The bubbles quickly rise in the water due to the buoyancy and drive the water upward during the rising process. After being filtered by the filter assembly 6, the water is discharged to realize the circulation purification and oxygenation. The specific working principle is as follows:

[0039] The lower part of the main body 1 is located at the bottom of the water container 12 filled with water, and the filter assembly 6 at the upper part is located above the water surface of the water container 12. Since the water level in the water container 12 is high, sufficient water pressure difference is generated. The lower the position, the greater the water pressure. The water in the water container 12 will automatically enter the fluid channel in the main body 1 from the pipeline structure of the water inlet 3 under the action of water pressure until it is level with the water level of the water container 12. The pipeline structure of the water inlet 3 extending outward and downward increases the water pressure difference and further restricts the escape of gas from the water inlet 3. Therefore, the gas delivered by the air pump 13 can only move upward at the bottom of the main body 1. In addition to the thrust of the air pump 13, the water is discharged upward from the water outlet 4 with smaller water pressure. Under the action of gravity, the water falls back to the bottom of the filter assembly 6. After being filtered by the filter material 11, the water falls from the discharge outlet 10 and flows into the water container 12. In this way, the water is filtered and the oxygen content of the water is increased at the same time due to the sufficient contact between the water and the gas. Example Two
