Problems solved by technology

However, the straight-line distance from the bubble to the water surface is short after the bubble is formed, and the bubble stays in the water for a short time after the bubble is formed, and it is difficult for the oxygen in the bubble to fully dissolve into the water.
When multiple bubbles are formed inside the liquid, the dissolved oxygen around the bubbles is saturated, and it is difficult for the oxygen to dissolve into the water. When the concentration of dissolved oxygen in the water diffuses, the oxygen inside the bubbles can continue to dissolve, which leads to the air introduced by the trachea. Or most of the pure oxygen is discharged into the air, and the efficiency is extremely low

Embodiment 2

[0030] Example two, see Figure 2-Figure 3 The bubble supporting and guiding mechanism is just an arc-shaped mesh plate, which is fixed at the end of the connecting pipe 200. After the bubbles come out, they only need to receive an upward buoyancy. Therefore, only an arc-shaped net plate can be used to block the bubbles. The arc-shaped net plate is used to fix the end of the connecting pipe to prevent the bubbles from passing through the connecting pipe. After coming out, continue to rise so that the bubbles can move forward along the extension direction of the screen. Since the bottom of the screen is open, the water near the screen can better mix with the entire water body, preventing the dissolved oxygen in the water near the screen from reaching saturation.

[0031] In some embodiments, the bubble supporting and guiding mechanism may be a round tube with only two ends open.

[0032] It should be understood that although the bubble supporting and guiding mechanism 300 is arran...

Abstract

The invention discloses an aeration device which comprises an aerator and a bubble supporting and guiding mechanism, the aerator comprises an air outlet, the bubble supporting and guiding mechanism istransversely arranged, the bubble supporting and guiding mechanism comprises a bubble inlet and a bubble outlet, and the bubble inlet is communicated with the air outlet. By additionally arranging the bubble supporting and guiding mechanism, after being treated by the aerator, bubbles are supported and guided by the bubble supporting and guiding mechanism and finally emerge from the water surface, so that the residence time of the bubbles in the water body is prolonged, oxygen in the bubbles has sufficient time to be dissolved in the water body, and the oxygen dissolving efficiency is effectively improved.

Description

Technical field [0001] The invention relates to the fields of aquaculture and environmental protection, in particular to a device for improving the efficiency of dissolved oxygen in water. Background technique [0002] In order to increase the amount of dissolved oxygen in aquaculture or environmentally friendly waters, aeration devices are generally installed in the water. Existing aeration devices generally include air pumps, air pipes, and aeration stones or pipes containing micropores. The principle is to discharge air or oxygen from the water through the aeration stones or pipes, forming bubbles, The liquid is in full contact and the oxygen is dissolved into the water. In order to increase the amount of dissolved oxygen, it is generally adopted to increase the amount of aeration bubbles, or reduce the diameter of the bubbles to increase the efficiency of dissolved oxygen. However, the linear distance from the nozzle to the water surface is short after the bubble is formed,...
