In order to obtain better treatment effects, the dissolved oxygen content in the wastewater should be between 2 and 4 mg·L-1. At this time, both aerobic bacteria and facultative bacteria can carry out aerobic respiration, so that the organic matter in the wastewater can be fully degraded. Usually, the dissolved oxygen content in sewage cannot meet the needs of aerobic bacteria to decompose organic matter. In the aerobic treatment of sewage, oxygen needs to be supplemented into the water, that is, aeration. Through aeration, the oxygen in the air can be dispersed into the sewage.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution: a diffused aerator, including an installation cylinder 1 and a gas delivery pipe 2 inserted into the installation cylinder 1, including,

[0028] At least four installation frames 3 are linearly arrayed and equally spaced along the air inlet direction and connected inside the installation cylinder 1, and the installation frames 3 are arranged in a ring shape;

[0029] At least six diffuser plate buckle groups 5 are connected to the inner surface of the installation frame 3 and are equally spaced in a circumferential array centered on the central axis of the installation frame 3;

[0030] A diffuser plate body 4 is inserted into the installation frame 3, and its quantity and position correspond to those of the installation frame 3.

[0031] It should be noted that the installation cylinder 1 can be installed vertically during installation, and the installation frame 3 can be connected to the inner wall of the installation cylinder 1 by welding or bolt fixation.

[0032] During specific implementation, in the process of wastewater treatment, gas enters the installation cylinder 1 through the gas pipeline 2. Along the gas inlet direction, at least four installation frames 3 are connected in the installation cylinder 1 at equal intervals. These installation frames 3 are distributed in a linear array, providing stable support and fixation for the internal structure of the entire aerator. The installation frame 3 is arranged in a ring shape, enabling the gas to flow more evenly inside it.

[0033] At least six diffuser plate buckle groups 5 are connected to the inner surface of the installation frame 3. These buckle groups are connected at equal intervals in a circumferential array centered on the central axis of the installation frame 3. When the diffuser plate body 4 is inserted into the installation frame 3, the diffuser plate buckle group 5 can firmly fix the diffuser plate body 4 to ensure that it does not shift during operation.

[0034] After the gas enters the installation cylinder 1, it successively passes through the diffuser plate bodies 4 inside each installation frame 3. Since the number and positions of the diffuser plate bodies 4 correspond to those of the installation frame 3, when the gas passes through the diffuser plate bodies 4, it will be dispersed into smaller bubbles by their special structures. In this way, the contact area between the gas and the wastewater is greatly increased, the aeration efficiency is improved, thereby better promoting the reaction of substances in the wastewater and enhancing the wastewater treatment effect. At the same time, in this setting, the gas pipeline 2 intakes gas from the center of the installation cylinder 1, with uniform force, making the installation cylinder 1 operate stably. Secondly, the multi-layer diffuser plate bodies 4 enhance the effect of separating and dispersing bubbles. At the same time, when the diffuser plate body 4 is blocked, the installation cylinder 1 automatically floats, facilitating inspection and cleaning.

[0035] Refer to Figure 4 , a plurality of connecting grooves 6 are formed on the diffuser plate body 4. The plurality of connecting grooves 6 are distributed at equal intervals in a circumferential array centered on the central axis of the diffuser plate body 4, and the connecting grooves 6 correspond to the diffuser plate buckle groups 5.

[0036] During specific implementation, a plurality of connecting grooves 6 are formed on the diffuser plate body 4. The plurality of connecting grooves 6 are distributed at equal intervals in a circumferential array centered on the central axis of the diffuser plate body 4, and the connecting grooves 6 correspond to the diffuser plate buckle groups 5. The provided connecting grooves 6 facilitate inserting the diffuser plate body 4 into the installation frame 3 and facilitate the installation of the diffuser plate body 4.

[0037] Refer to Figures 2 to 5 , two limiting plates are provided inside the diffuser plate buckle group 5. As the diffuser plate body 4 rotates clockwise or counterclockwise around the central axis of the gas pipeline 2, the diffuser plate buckle group 5 gradually limits the diffuser plate body 4.

[0038] It should be noted that the shape of the limiting plate can be triangular or semi-circular or rectangular. Here, a rectangular shape is selected for convenient processing.

[0039] In specific implementation, first, there are two limiting plates in the diffuser plate buckle group 5. This design ensures the stability of the diffuser plate body 4 during installation and use. When the diffuser plate body 4 rotates clockwise or counterclockwise around the central axis of the air delivery pipe 2, the diffuser plate buckle group 5 can gradually limit the diffuser plate body 4. This can prevent the diffuser plate body 4 from shifting or loosening due to gas impact or other external forces during the aeration process, ensuring the normal operation of the aerator.

[0040] Secondly, the stable diffuser plate body 4 helps to improve the aeration effect. Since the diffuser plate body 4 can be firmly fixed in the installation frame 3, its gas dispersion effect is more stable and reliable. When the gas passes through the diffuser plate body 4, it can be evenly dispersed into smaller bubbles, increasing the contact area between the gas and the wastewater, thereby improving the aeration efficiency, promoting the reaction of substances in the wastewater, and enhancing the wastewater treatment effect.

[0041] In addition, this limiting design also facilitates installation and maintenance. During the installation process, the operator can simply rotate the diffuser plate body 4 to make it cooperate with the diffuser plate buckle group 5 to quickly achieve installation positioning. During maintenance, the diffuser plate body 4 can also be easily disassembled and replaced, improving work efficiency and reducing maintenance costs.

[0042] Refer to Figures 2 to 5 , a plurality of mesh holes 7 are formed on the diffuser plate body 4, and the plurality of mesh holes 7 are evenly distributed in a circumferential array.

[0043] Specifically, on the one hand, this design greatly improves the uniformity of aeration. When the gas passes through the diffuser plate body 4, since the plurality of mesh holes 7 are evenly distributed in a circumferential array, the gas can pass through the diffuser plate body 4 evenly from all directions, and then be dispersed into finer and more uniform bubbles and enter the wastewater. This helps to ensure that different regions in the wastewater can fully contact the aeration gas, improving the overall effect and quality of wastewater treatment.

[0044] On the other hand, it enhances the degree of gas dispersion. The numerous evenly distributed mesh holes 7 provide more dispersion channels for the gas, enabling the gas to be more efficiently divided into small bubbles. This increases the contact area between the gas and the wastewater, promotes the full reaction of the gas with the substances in the wastewater, and speeds up the process of wastewater treatment.

[0045] In addition, the evenly distributed mesh holes 7 also improve the durability of the diffuser plate body 4. Because the gas dispersion is more uniform, it reduces the risk of damage to the diffuser plate body 4 caused by excessive local pressure, extends the service life of the diffuser plate body 4, and reduces the maintenance cost of the equipment.

[0046] Refer to Figures 1 to 2, a sealing ring is provided at the connection between the diffuser plate body 4 and the gas pipeline 2, and the material of the sealing ring is rubber.

[0047] Specifically, first of all, the rubber sealing ring can closely fit between the diffuser plate body 4 and the gas pipeline 2, effectively preventing gas leakage. Ensure that the gas transported from the gas pipeline 2 can all pass through the diffuser plate body 4 for dispersed aeration, improving the gas utilization efficiency, avoiding energy waste, and ensuring the efficient operation of the aerator.

[0048] Secondly, it helps the diffuser plate body 4 to stably play its role in dispersing gas, reducing the impact and damage to the equipment caused by unstable pressure, and extending the service life of the equipment.

[0049] Furthermore, the rubber material has good elasticity and wear resistance. It can adapt to the slight vibration and friction between the diffuser plate body 4 and the gas pipeline 2 during operation, and maintain the sealing performance for a long time.

[0050] On the opposite sides of the two limiting plates, anti-slip patterns are integrally formed, which improves the fixing effect on the diffuser plate body 4.

[0051] Please refer to Figure 5 , the distance between the two limiting plates is greater than the thickness of the diffuser plate body 4;

[0052] Specifically, this setting facilitates the insertion of the diffuser plate body 4 between the two limiting plates, facilitating the fixation of the diffuser plate body 4.

[0053] Please refer to Figure 1 and Figure 2 , the installation cylinder 1 is in the shape of a straight pipe, and both ends of the installation cylinder 1 communicate with each other.

[0054] Specifically, this setting facilitates the insertion of the gas pipeline 2 into the installation cylinder 1.

[0055] Working principle: During the wastewater treatment process, gas enters the installation cylinder 1 through the gas pipeline 2. Along the intake direction, at least four installation frames 3 are connected at equal intervals inside the installation cylinder 1, and these installation frames 3 are distributed in a linear array, providing stable support and fixation for the internal structure of the entire aerator. The installation frame 3 is in a ring shape, enabling the gas to flow more evenly inside it.

[0056] The inner surface of the installation frame 3 is connected to at least six diffuser plate buckle groups 5, and these buckle groups are connected at equal intervals in a circumferential array centered on the central axis of the installation frame 3. When the diffuser plate body 4 is inserted into the installation frame 3, the diffuser plate buckle groups 5 can firmly fix the diffuser plate body 4, ensuring that it will not shift during operation.

[0057] After the gas enters the installation cylinder 1, it successively passes through the diffuser disk bodies 4 in each installation frame 3. Since the quantity and positions of the diffuser disk bodies 4 correspond to those of the installation frames 3, when the gas passes through the diffuser disk bodies 4, it will be dispersed into smaller bubbles by their special structures. In this way, the contact area between the gas and the wastewater is greatly increased, the aeration efficiency is improved, so as to better promote the reaction of substances in the wastewater and enhance the wastewater treatment effect. At the same time, in this setting, the air delivery pipe 2 intakes air from the center of the installation cylinder 1, with uniform stress, making the installation cylinder 1 operate stably. Secondly, the effect of separating and dispersing bubbles is improved by multiple layers of diffuser disk bodies 4. At the same time, when the diffuser disk bodies 4 are blocked, the installation cylinder 1 automatically floats upward, which is convenient for inspection and cleaning.

[0058] The above embodiments are only used to illustrate the present invention rather than to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement to the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the present invention are covered by the scope of the claims of the present invention.
