[0002] Aeration and oxygenation technology is a process of forcing oxygen in the air to transfer into the liquid, the purpose of which is to enable the water to obtain sufficient dissolved oxygen, and to perform aeration in the aerobic pool. It can also prevent the suspended matter in the pool from sinking, thereby increasing the contact time and efficiency of organic matter, microorganisms and dissolved oxygen in the aerobic pool. When aerating the pool, an aerator is used, which is connected to a booster device such as an air pump outside the pool. There are many types of aerators, which can be divided into tubular aerators, disc aerators, and hanging chain aerators according to different applicable scopes. When installing the above-mentioned aerators, especially the disc aerators, the aerator needs to be connected to the air pipe, and then the pipe with the aerator installed is fixed to the bottom of the aerobic pool. The fixed type uses a tie or a clamp to cooperate with other components to fix the pipe, which has many defects. On the one hand, the installation is more complicated and needs to be installed after the pool is not filled with water or the water is drained. Moreover, for the pool bottom that already has aeration equipment, it needs to be removed before installation. On the other hand, it is fixedly installed on the pool bottom, which increases the difficulty of repairing or maintaining the aerator. Utility Model Content

[0025] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0026] Example

[0027] As mentioned in the background technology, the aerobic pool 9 needs to use an aeration system to increase the dissolved oxygen in the pool and improve the sewage treatment capacity, and an aeration device usually needs to be installed in the aeration system. However, the disc aerator 4 of the existing aeration device is usually fixed to the bottom of the aerobic pool 9 with a pipeline, which has many disadvantages for both the early installation and the later inspection and maintenance. During installation, it is necessary to ensure that there is no water in the pool, which increases the installation requirements. During inspection and maintenance, the water in the pool needs to be drained or personnel need to go into the water to disassemble it, which makes the use of the aerator 4 inconvenient. Therefore, the inventor has made improvements based on the existing installation of the aerator 4, designed a new aeration device and applied it to the corresponding aeration system, which is explained in detail below with reference to the drawings.

[0028] This embodiment provides a self-sinking aeration device, combined with Figure 1 and Figure 2, including an air intake main pipe 1 and a plurality of air intake branch pipes 2, the air intake main pipe 1 and the plurality of air intake branch pipes 2 are assembled from stainless steel pipes, the specific model adopts DN25, which can improve the service life in the aerobic tank 9, the outlet end of the air intake main pipe 1 is connected to the air intake ends of the plurality of air intake branch pipes 2 through a multi-way pipe 3, and in the present embodiment, four air intake branch pipes 2 are provided, all of which are arranged horizontally, and the extension directions are perpendicular to each other, and correspondingly, the multi-way pipe 3 adopts a five-way pipe, the air inlet of the five-way pipe is arranged vertically to the four air outlets, and the air inlet is arranged vertically upward, so that the air intake main pipe 1 is arranged vertically upward, which is convenient for installation with the aeration system, and enables the gas to be transported vertically, thereby ensuring the gas transportation efficiency, and then ensuring the aeration effect.

[0029] On the basis of the above structure, in order to be able to aerate the pool, the outlet ends of the plurality of air inlet pipes 2 are connected to the aerators 4. In the present embodiment, four aerators 4 are arranged corresponding to the air inlet pipes 2 for each group of aeration devices, and the aerators 4 are disc-type, which are existing purchased components, and the air outlet holes of the aerators 4 are arranged vertically upward. Specifically, the air outlet end of the air inlet pipe 2 is connected to a right-angle elbow 8, and the air outlet end of the right-angle elbow 8 is arranged vertically upward and connected to the aerator 4, so that the aerator 4 is installed horizontally and the air outlet holes are facing upward. During aeration, the gas ejected from the air outlet holes flows upward from the bottom of the pool.

[0030] One of the main design points of this scheme is that a plurality of counterweight legs 5 are connected to the side of the plurality of air inlet branch pipes 2 away from the aerator 4, and extend toward the side away from the aerator 4, that is, the counterweight legs 5 extend vertically downward, and can support the air inlet branch pipes 2, and the design that mainly plays a counterweight role is that the counterweight legs 5 are hollow tubes with closed lower ends, and DN25 stainless steel pipes are used like the air inlet branch pipes 2, and the upper ends are fixedly connected to the corresponding air inlet branch pipes 2, and can be fixed by welding or the like, and the lower end can be closed by a movable closure, that is, it can be closed in the form of a pipe cap, and before closing, a counterweight 7 is filled inside, and specifically, a material with a larger mass, such as iron sand, can be used. The number of counterweight legs 5 is set according to the depth of the aerobic pool 9, and generally, one counterweight leg is connected to the bottom of each air inlet branch pipe 2.

[0031] The above is an introduction to the self-sinking aeration device in this scheme. The following is a detailed introduction to the installation of the aeration device and the aeration system.

[0032] This embodiment provides an aeration system, combined with Figure 3, an aeration device is installed in the aeration system, wherein the aeration system includes an air supply component installed at the upper end of the aerobic tank 9, the air supply component is connected to an air branch pipe 10, and multiple air branch pipes 10 can be designed. Specifically, the air supply component includes an air main pipe 13, and the air main pipe 13 is connected to an air supply source, and the air supply source can provide an air source for the entire aeration system. Specifically, an air pump and other components can be used, which are existing components and are not described in detail. The air main pipe 13 is connected to multiple air branch pipes 10 through a connecting pipe 14, and a valve 15 is provided between the two. The input of air can be controlled by the design of the valve 15.

[0033] On the basis of the above structure, the air branch pipe 10 is arranged across the aerobic tank 9, and in order to improve the stability of the air branch pipe 10, fasteners 16 are installed at both ends of the top of the aerobic tank 9, which can be fixed by clamps or winding bands, and the air branch pipe 10 adopts PE pipes, which has low material cost and is easy and quick to install and use. The air branch pipe 10 is connected to multiple vertical pipes 12 through multiple tee pipes 11, and the vertical pipes 12 extend downward into the aerobic tank 9, but the vertical pipes 12 adopt hoses, which are convenient for lifting, installing or disassembling the aeration device, and the bottom end is connected to the air inlet end of the air inlet main pipe 1. In order to facilitate the connection between the vertical pipe 12 and the air inlet main pipe 1, and make the two The connection is more stable. A stop thread 6 is provided on the outside of the air inlet end of the air inlet main pipe 1. Correspondingly, an internal thread is provided inside the bottom end of the vertical pipe 12. The two are connected and fixed by the meshing of the threads. During installation, the vertical pipe 12 is lifted, and the end is connected to the air inlet main pipe 1 through the thread. Then, the aeration device is placed in the pool. The weight of the aerator 4 and the weight of the counterweight leg 5 can move downward in the water until the counterweight leg 5 contacts the bottom of the pool. Then, the position of the aeration device can be fine-tuned by lifting the vertical pipe 12. When the aeration device needs to be inspected or maintained, the entire aeration device can be lifted by lifting the vertical pipe 12, and the aeration device can be disassembled, thereby realizing installation or inspection with water in the pool.

[0034] It should be noted that the length of the counterweight leg 5 has a certain design, wherein the length of the counterweight leg 5 is 20cm-80cm, which is specifically designed according to the depth of the aerobic pool 9. The height of the counterweight leg 5 is 1 / 15-1 / 5 of the depth of the aerobic pool 9, ensuring that the aerator 4 can be located at a lower position in the aerobic pool 9, so that the gas can be sprayed upward at a lower position, thereby improving the oxygen supply effect in the pool. However, it is not advisable to compress the height of the counterweight leg 5 too low. Reducing the weight of the counterweight leg 5 will affect the counterweight, and then affect the stability of the aerator 4 at the bottom of the pool.
