[0002] Aeration refers to the process of forcibly transferring and dispersing gas (usually oxygen in the air) into a liquid, with the aim of obtaining sufficient dissolved oxygen. In addition, aeration also serves to prevent the suspension in the pool from sinking and to enhance the contact between the organic matter in the pool, microorganisms, and dissolved oxygen. Thus, it ensures that the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen. The aeration process often appears in the biochemical treatment processes of industrial sewage such as textile, printing and dyeing, papermaking, and chemical engineering, as well as urban domestic sewage, and various breeding fields and salt-making fields. Since dissolved oxygen is required in biochemical sewage treatment, corresponding aerators are needed to achieve aeration, and there are a wide variety of aerators at home and abroad.

[0003] In the prior art, the position of the traditional aeration device set at the bottom of the water is fixed. When aerating pools with different depths, the position setting of the aeration device is crucial. Appropriately adjusting the position of the aeration device can effectively increase the aeration efficiency, enhance the aeration effect inside the pool, and prevent the depth change of the aeration device caused by the change in the water depth from affecting the aeration effect.

Specific embodiments

[0018] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] See Figure 1 and Figure 2 , the present utility model provides a depth-adjustable underwater aeration device. The depth-adjustable underwater aeration device includes an intake main pipe 1 with a plurality of outlet pipes 2 provided on the outside. The intake port of the intake main pipe 1 is connected to a gas supply mechanism, and the gas supply mechanism supplies compressed air into the interior of the intake main pipe 1 to ensure that air is discharged from the aeration head 4 and enters the interior of the water for aerating the water; an aeration head 4 slidably connected to the outlet pipe 2, and at least one intermediate sliding sleeve 3 is provided between the aeration head 4 and the outlet pipe 2. By setting the aeration head 4 to a sliding structure, when the liquid level in the pool changes, the aeration head 4 slides to adjust the position of the aeration head 4 relative to the liquid level, preventing the blade from descending or rising, resulting in the position of the aeration head 4 being too deep or too shallow and affecting the aeration effect of the liquid. A control member 6 for controlling the position of the aeration head 4 is provided at the top of the aeration head 4, and a pull rope 5 is provided between the control member 6 and the aeration head 4. When the height of the control member 6 changes on the water surface, the control member 6 pulls the aeration head 4 to slide on the outlet pipe 2 to ensure that the position of the aeration head 4 can be controlled by the control member 6, preventing the position of the aeration head 4 in the liquid from changing due to the change of the liquid level and affecting the aeration effect.

[0020] In addition, upper limiting flanges are provided at the top of the air outlet pipe 2 and the top of the middle sliding sleeve 3 of the present utility model. A sliding sleeve 41 is provided at the bottom of the aeration head 4. The aeration head 4 achieves a normal aeration effect through an aeration disc 42. At the same time, the sliding sleeve 41 is arranged at the bottom of the aeration disc 42. Lower limiting flanges are provided at the bottom of the sliding sleeve 41 and the middle sliding sleeve 3. The adjacent upper and lower limiting flanges cooperate with each other to limit the position of the aeration head 4, preventing the sliding sleeve 41 or the middle sliding sleeve 3 from falling off and affecting the use of the aeration device.

[0021] See Figure 1 , Figure 2 and Figure 3 , Further, the control member 6 of the present utility model is a float. The pull rope 5 is threaded through the control member 6. A wire winding wheel 7 for controlling the length of the pull rope 5 is provided at the top of the control member 6. By rotating the wire winding wheel 7, the length of the pull rope 5 between the control member 6 and the aeration head 4 is controlled to ensure that the depth between the aeration head 4 and the liquid surface can be controlled, thereby realizing the control of the aeration effect. The end of the pull rope 5 is fixedly provided on the wire winding wheel 7. A rotation hole 61 is provided at the top of the control member 6. A thrust spring 62 for moving the control member 6 in the direction of pressing the pull rope 5 is provided inside the rotation hole 61. After adjusting the length of the pull rope 5, the lower limiting plate 74 at the bottom of the control member 6 presses the pull rope 5 through the thrust spring 62 to prevent the pull rope 5 from moving around and affecting the depth of the aeration head 4.

[0022] See Figure 4 , Preferably, the wire winding wheel 7 of the present utility model includes a wire winding shaft 73 for winding the pull rope 5 and upper and lower limiting plates 72 and 74 are respectively arranged at both ends. A sliding part is provided at the top of the upper limiting plate 72. A leverage handle 71 is provided at the top of the sliding part. By pulling and rotating the wire winding wheel 7 through the leverage handle 71, it is convenient to adjust the length of the pull rope 5. The intake main pipe 1 is arranged at the bottom of the water, and the air outlet of the air outlet pipe 2 is vertically upward to ensure the normal setting and aeration effect of the aeration head 4.

[0023] In this embodiment, in combination with Figures 1 to 4, during use, first determine the height of the aeration head 4 from the water surface. By pulling the leverage handle 71, at this time, rotate the leverage handle 71, and the pull rope 5 extends and retracts on the winding shaft 73 to complete the adjustment of the length of the pull rope 5. Release the leverage handle 71, and under the action of the thrust spring 62, the lower limit plate 74 is pressed tightly against the bottom of the rotation hole 61. At this time, the pull rope 5 is pressed and tightened by the limit plate, and the length adjustment of the pull rope 5 is completed. Then, arrange the main air inlet pipe 1 at the bottom of the pool, and then fill the pool with water. At this time, as the water level rises, the control member 6 floats on the water surface. When the water level rises, the height of the water surface increases, driving the control member 6 to rise. When the control member 6 rises to tighten the pull rope 5, at this time, the control member 6 pulls the aeration disc 42 to rise, ensuring that the height between the aeration disc and the water surface remains constant and ensuring the aeration effect.

[0024] In summary, the present invention provides a depth-adjustable underwater aeration device, including: a main air inlet pipe with a plurality of air outlet pipes arranged on the outside, the air inlet of the main air inlet pipe is connected to a gas supply mechanism, and the gas supply mechanism supplies compressed air into the main air inlet pipe to ensure that air is discharged from the aeration head and enters the water to aerate the water; an aeration head slidably connected to the air outlet pipe, and at least one intermediate sliding sleeve is provided between the aeration head and the air outlet pipe. By setting the aeration head to a sliding structure, when the liquid level in the pool changes, the position of the aeration head relative to the liquid level is adjusted by the sliding of the aeration head, preventing the blade from dropping or rising, resulting in the position of the aeration head being too deep or too shallow and affecting the aeration effect of the liquid. A control member for controlling the position of the aeration head is provided at the top of the aeration head, and a pull rope is provided between the control member and the aeration head. When the height of the water surface changes, the control member pulls the aeration head to slide on the air outlet pipe, ensuring that the position of the aeration head can be controlled by the control member and preventing the position of the aeration head in the liquid from changing due to the change of the liquid level and affecting the aeration effect. In summary, the technical effect produced by the present invention is to automatically adjust the depth according to the different depths of the pool, ensuring that the aeration device can be maintained at a certain position from the depth of the pool and optimizing the aeration effect.
