The air inlet structure is one of the key components of the aeration oxidation tank, which directly affects the aeration effect and treatment efficiency.

[0003] The aeration structure is arranged in the oxidation tank. Since the content of suspended solids in the sewage is high, it is easy to block the aeration head, or the content of organic matter in the sewage is high, and it is easy to form a biological film during the aeration process. The gradually thickened biological film adheres to the aeration head and will also cause blockage problems. In addition, the uniformity of aeration of the existing air inlet structure is poor, which is not conducive to accelerating the sewage treatment process. Content of the Utility Model

[0006] Further, the aeration cylinder is provided with an installation part. The limiting member includes an installation cylinder and a limiting head located above the installation cylinder. The installation cylinder and the limiting head are fixedly connected by a connecting frame;

[0007] The installation cylinder is installed at the installation part.

[0008] Further, the limiting head is provided with a limiting hole.

[0009] Further, a baffle is arranged in the aeration cylinder, and an eccentric hole is arranged on the baffle.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will briefly introduce the drawings required for use in the embodiments. Obviously, the drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0022] The present utility model will be described in detail below in conjunction with the drawings and specific embodiments. The embodiments cannot be described in detail one by one here, but the embodiments of the present utility model are not limited to the following embodiments.

[0023] Combined with Figures 1-4As shown in the figure, the present utility model provides an air inlet structure for a sewage aeration oxidation tank, which includes an air inlet main pipe 1, a plurality of air inlet branch pipes 2 connected to the air inlet main pipe 1, and a plurality of aeration structures 3 installed on the air inlet branch pipes 2.

[0024] According to an embodiment of the present utility model, in practical applications, the air inlet structure of the sewage aeration oxidation tank of the present utility model can be placed in the oxidation tank, the air supply device is connected to the air inlet main pipe 1, and aeration operation is realized in the oxidation tank through the air inlet main pipe 1, the air inlet branch pipes 2, and the aeration structures 3.

[0025] In this embodiment, the aeration structure 3 includes an aeration cylinder 4, a guiding cover 5, and a limiting member 6. Among them, the aeration cylinder 4 is communicated with the air inlet branch pipe 2. An installation part 41 is provided on the outer periphery of the aeration cylinder 4, and a baffle 42 is provided inside the aeration cylinder 4. There is a certain distance between the baffle 42 and the upper end of the aeration cylinder 4, and an eccentric hole 43 is provided on the baffle 42.

[0026] In this embodiment, the guiding cover 5 is supported on the aeration cylinder 4, and the guiding cover 5 is slidably matched with the aeration cylinder 4. Specifically, the guiding cover 5 includes a cover plate 51, sliding rods 52 located on the upper and lower sides of the cover plate 51 respectively, and a rotating sliding structure 53. The rotating sliding structure 53 extends into the aeration cylinder 4 and is located above the baffle 42. In this embodiment, the rotating sliding structure 53 includes symmetrically arranged arc-shaped plates 531 and guiding curved surface structures 532, and the eccentric hole 43 is located below the guiding curved surface structure 532.

[0027] According to an embodiment of the present utility model, the limiting member 6 includes an installation cylinder 61 and a limiting head 62 located above the installation cylinder 61. The installation cylinder 61 and the limiting head 62 are fixedly connected through a connecting frame 63.
