Description

Technical Field

[0001] This utility model relates to the field of water oxygenation technology, specifically to a water oxygenator for fish farming. Background Technology

[0002] The working principle of an aerator is mainly to effectively introduce oxygen from the air into the water through mechanical devices, thereby increasing the dissolved oxygen content in the water. Aerators typically use power sources such as electric motors or diesel engines to drive the working components. They draw in outside air through an air intake device, compress it to form a high-pressure airflow, and finally, a water spray device cuts the gas into tiny bubbles and distributes them evenly in the water flow. These bubbles rise and vibrate in the water, making full contact with the water, allowing the oxygen to gradually dissolve into the water, while simultaneously promoting water convection and mixing, helping to distribute the oxygen more evenly.

[0003] Existing aerators draw in air and discharge it through pipes located in the water. As a result, the air mixes with the water in the pond. However, the mixing between the air and water is not sufficient. After the air bubbles in the water, a large amount of air is directly discharged from the water, thus reducing the amount of dissolved air in the water. Utility Model Content

[0004] In view of the problems existing in the current aerator for fish farming water, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an aerator for aquaculture, which solves the problem of existing aerators where the air drawn in is discharged through a pipe located in the water, thus mixing the air with the water in the pond. However, the mixing between the air and water is not sufficient, and after the air bubbles in the water, a large amount of air is directly discharged from the water, resulting in less dissolved air in the water.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] A fish farming aerator includes a housing, in which an air extractor and a water pump are installed.

The inlet of the water pump is connected to a first inlet pipe, the end of the first inlet pipe is connected to a second inlet pipe, and the second inlet pipe has through holes at equal intervals.

[0016] Compared with existing technologies:

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] This utility model provides an aerator for aquaculture water. Please refer to [link / reference]. Figure 1-5 The system includes a housing 1, inside which an air extractor 15 and a water pump 16 are installed. The outlet 6 of the water pump 16 is connected to a first water pipe 9, and the end of the first water pipe 9 is fixedly connected to a dissolving pipe 11. Specifically, the first water pipe 9 and the dissolving pipe 11 are connected by an elbow 10. The output end 8 of the air extractor 15 is fixedly connected to a first air pipe 7, and the end of the first air pipe 7 is fixedly connected to a horizontal air pipe 13. The horizontal air pipe 13 is connected to the dissolving pipe 11 through multiple branch pipes 14. The water extracted by the air extractor 15 and the air extracted by the water pump 16 dissolve in each other in the dissolving pipe 11, thereby achieving pre-mixing of air and water, resulting in a greater amount of dissolved air and enhanced oxygenation effect.

[0027] The bottom of the horizontal air pipe 13 is provided with multiple air outlets at equal intervals, and the top of the dissolving pipe 11 is provided with multiple air inlets at equal intervals. The two ends of each branch pipe 14 are respectively connected to the corresponding air outlet and air inlet. The air in the horizontal air pipe 13 enters the dissolving pipe 11 from multiple places to avoid air accumulation, thereby making the dissolution between air and water more complete.

[0028] The housing 1 has two cavities. The air extractor 15 and the water pump 16 are respectively installed in the two cavities of the housing 1. The front end of the housing 1 is hinged to the door 2, and the door 2 is equipped with louvers.

[0029] A one-way valve 12 is installed on the first air pipe 7. The air inlet 4 of the air pump 15 is connected to a filter cylinder 5. Specifically, one end of the filter cylinder 5 has an interface 51, and the interface 51 and the air inlet 4 are fixed together by bolts. A support ring 17 is welded inside the filter cylinder 5, and a filter screen 18 is installed on the support ring 17. Specifically, a groove is opened on the support ring 17, and a magnet 171 is installed in the groove. The magnet 171 magnetically attracts the filter screen 18, so that the filter screen 18 can be easily disassembled and installed, and it is convenient for future maintenance of the filter screen 18.

[0030] The dissolving pipe 11 is connected to the second water pipe 25 via an elbow 10. The end of the second water pipe 25 is connected to the outlet pipe 20 via an elbow 10. The outlet pipe 20 has through holes at equal intervals. The inlet 3 of the water pump 16 is connected to the first inlet pipe 19. The end of the first inlet pipe 19 is connected to the second inlet pipe 21. The second inlet pipe 21 has through holes at equal intervals. Thus, water from multiple locations in the pond enters the second inlet pipe 21 through the through holes, causing disturbance in multiple areas of the water body. At the same time, water in the outlet pipe 20 is drained through multiple through holes, further disturbing the water and achieving sufficient disturbance of the water body, which helps to increase the dissolved oxygen level. Furthermore, the premixed water and air are discharged from multiple locations in the water body, further ensuring sufficient contact between the air and the water body, which also increases the dissolved oxygen level.

[0031] A first fitting ring 22 and a second fitting ring 24 are respectively fitted onto the outlet pipe 20 and the inlet pipe 21. The bottom of the first fitting ring 22 and the second fitting ring 24 are fixedly connected to a vertical pole, which is fixed to the bottom of the pond.

[0032] In practical use:

[0033] The air drawn by the vacuum pump 15 and the water drawn by the water pump 16 dissolve each other in the dissolving pipe 11, thereby achieving premixing of air and water.

[0034] After the device is installed, the water in the premixed air in the dissolving pipe 11 is discharged through the outlet pipe 20, and then the air continues to mix and dissolve with the water, thereby increasing the dissolved oxygen content.

[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
