Description

Technical Field

[0001] The utility model relates to an aeration device, in particular to a rotary aeration device used for sewage treatment. Background Art

[0002] In the traditional sewage treatment process, aeration is considered a vital step. Through aeration, oxygen can be injected into the sewage, thereby increasing the dissolved oxygen content in the sewage. This process is essential for accelerating the decomposition and purification of organic matter in sewage because it provides the necessary oxygen for microorganisms to perform aerobic respiration and decompose organic matter.

[0003] However, traditional static aeration methods have obvious drawbacks. The main problems are low aeration efficiency and uneven gas distribution. Since static aeration equipment is fixed in position, they often cannot evenly inject oxygen into every corner of the sewage. This results in sewage in some areas not getting enough oxygen supply, while other areas may be over-aerated. This problem directly affects the effect and efficiency of sewage treatment, making the entire treatment process less than ideal.

[0004] In order to solve these problems, we proposed an innovative technical solution of a rotary aeration device. Utility Model Content

[0007] A waterproof driving device is fixedly provided on the top of the support column;

[0008] An upper rotating disc is fixedly provided on the upper part of the waterproof driving device, and an auxiliary frame is fixedly provided at the edge of the upper rotating disc. The auxiliary frame is fixedly provided along the edge of the upper rotating disc, and the number of the auxiliary frames is several and is evenly arranged around the supporting column;

[0016] As an improvement, the aeration tube body is in a U-shape with the opening facing inwards.

[0017] As an improvement, the number of the aeration pipe bodies is equal to the number of the auxiliary frames.

[0018] Compared with the prior art, the utility model has the following advantages: Improved aeration efficiency: The rotation of the auxiliary frame drives the aeration tube to rotate in the sewage. This dynamic aeration method effectively increases the contact area between the gas and the sewage, thereby significantly improving the aeration efficiency.

[0035] 1. Structure description:

[0036] The rotary aeration device is mainly composed of the following parts:

[0037] Support column 101: adopts a two-stage controllable telescopic rod design with a height-adjustable function. Its lower part is equipped with a support plate 102 for enhancing the stability of the device and distributing the load.

[0038] Waterproof driving device 201: This device is fixed on the top of the supporting column 101, provides power for the device, and has waterproof performance to adapt to the sewage treatment environment.

[0039] Rotating platform 202: installed on the upper part of the supporting column 101, and designed to be able to rotate freely relative to the supporting column.

[0040] The upper rotating disk 203 is fixed on the upper part of the waterproof driving device 201 and rotates with the operation of the driving device.

[0041] Auxiliary frames 204: These frames are evenly fixed on the edge of the upper rotating disk 203, and there are three of them, which are evenly distributed around the support column 101. The upper part of each auxiliary frame 204 is connected to the outer rotating ring of the rotating platform 202, and the middle and lower parts are designed as a U-shaped structure with the opening facing inward. This design enhances the stability and rotation efficiency of the device.

[0042] Upper support frame 301: The two sides of the frame are fixed to the two side edges of the sewage treatment aeration tank for overall support and stabilization of the device.

[0043] Gas rotating joint 205: installed in the middle of the upper support frame 301, allowing the gas pipeline to remain connected when the device rotates.

[0046] Aeration pipe body 208: designed as a U-shaped structure with the opening facing inward, fixed to the middle and lower part of the auxiliary frame body 204 and rotated with it. These aeration pipe bodies are responsible for injecting gas into the sewage to achieve efficient aeration.

[0047] 2. Usage:

[0048] Placement and fixing:

[0049] First, the support column 101 is stably placed in the sewage treatment tank through the support plate 102 at the bottom thereof, and the placement position is ensured to be stable to prevent the device from tilting or shifting during operation.

[0050] According to the depth of the sewage treatment tank and actual needs, the height of the support column 101 is adjusted. Since the support column is a two-stage controllable telescopic rod, the height can be easily adjusted.

[0051] Install the upper support frame:

[0052] Make sure that both sides of the upper support frame 301 are firmly fixed to the edges of both sides of the sewage treatment tank. This step is crucial because it will provide the necessary stability and support for the entire device.

[0053] Connect the gas source:

[0054] Connect the air inlet pipe 206 to an external air source and ensure that the connection is well sealed to prevent gas leakage.

[0055] Check and ensure that the gas can smoothly pass through the gas rotating joint 205, the connecting pipe body 207, and finally enter the aeration pipe body 208. This is a key step to achieve an effective aeration process.

[0056] Up and running:

[0057] Start the waterproof driving device 201. As the driving device operates, the upper rotating disk 203 and the auxiliary frame 204 will start to rotate.

[0058] The rotation of the auxiliary frame 204 drives the aeration pipe 208 to perform rotational aeration in the sewage. This rotational action helps to increase the contact area between the gas and the sewage, thereby improving the aeration efficiency.

[0059] Adjustment and optimization:

[0060] During the operation of the device, the aeration time and gas flow rate are adjusted according to actual needs and sewage treatment effects.

[0061] The best sewage treatment effect can be achieved through continuous adjustment and optimization, which includes monitoring the dissolved oxygen content in sewage, observing the clarity of sewage, and checking the chemical oxygen demand (COD) of the treated sewage.

[0062] Improve aeration efficiency: The rotation of the auxiliary frame 204 drives the aeration pipe 208 to rotate in the sewage. This dynamic aeration method effectively increases the contact area between the gas and the sewage, thereby significantly improving the aeration efficiency. The rotation action ensures that every corner of the sewage can evenly receive the injection of gas, promoting the dissolution of oxygen and the oxidation and decomposition of organic matter in the sewage.

[0063] Gas connectivity: The stable connection between the air inlet pipe 206 and the external air source, and the ingenious design of the gas rotating joint 205 allow the gas pipeline to remain connected when the device rotates. This feature ensures that the gas can be continuously and stably delivered to the aeration pipe 208, providing uninterrupted aeration support for the sewage treatment process.

[0064] Height adjustable: The support column 101 is designed as a two-stage controllable telescopic rod, so that the height of the device can be adjusted according to the depth of the sewage treatment tank and actual needs. This flexibility ensures that the device can play the best effect in treatment tanks of different depths, and is also easy to install and maintain.

[0065] Strong stability: The design of the upper support frame 301 not only provides a solid support for the entire device, but also enhances the stability of the device. Its two sides are fixed to the edge of the sewage treatment tank, ensuring that the device can maintain stable operation even during strong rotation and aeration, thereby extending the service life of the equipment.

[0066] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
