Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an air separation and aeration device suitable for sewage treatment. Background Art

[0002] With the acceleration of industrialization and urbanization, the discharge of domestic and industrial wastewater continues to increase, causing serious pollution to the water environment. To protect water resources and the ecological environment, improving sewage treatment efficiency has become a top priority. Traditional aeration methods such as perforated tube aeration and surface aeration have problems such as uneven aeration, low oxygen utilization, high energy consumption, and difficult maintenance.

[0003] In actual use, the large volume of bubbles means that a single bubble carries more oxygen, but it also means that the contact area with the sewage during the bubble's rise is smaller, resulting in reduced oxygen transfer efficiency, which is not conducive to the respiration of microorganisms and the oxidative decomposition of sewage. The uneven distribution of bubbles will lead to insufficient oxygen supply in some areas of the sewage, while other areas may be overexposed. Utility Model Content

[0004] The purpose of the utility model is to provide a suitable air distribution aeration device for sewage treatment. The design of the arc-shaped fan blades can distribute the air in a more uniform manner to the entire sewage treatment area. This uniform aeration helps to increase the solubility of oxygen in sewage, promote the activity of microorganisms, and thus improve the efficiency of sewage treatment. The airflow generated by the rotation of the arc-shaped fan blades can effectively stir the sewage, so that pollutants such as suspended matter and organic matter are fully in contact with oxygen, accelerating the decomposition process. The air diffusion holes on the air diffusion pipe are designed to decompose the air into smaller bubbles. These small bubbles can more easily penetrate the suspended matter in the sewage, thereby improving the utilization rate of oxygen.

[0005] To achieve the above-mentioned objectives, a suitable sewage treatment air distribution aeration device is provided, comprising: a first fixed column, the bottom end of the first fixed column being fixedly connected to a motor, the output end of the motor being fixedly connected to a first rotating column, the bottom end of the first rotating column being fixedly connected to a second fixed column, the second fixed column being fixedly connected to the second rotating column via a first bolt, the circumferential surface of the second rotating column being fixedly connected to an arc-shaped fan blade, the circumferential surface of the arc-shaped fan blade being fixedly connected to an air diffusion pipe, the circumferential surface of the air diffusion pipe being provided with air diffusion holes. This design helps to improve bubble dispersion and oxygen utilization, thereby enhancing the sewage treatment effect.

[0006] According to the applicable sewage treatment air distribution and aeration device, a spiral block is fixedly connected to the circumference of the second rotating column, and the cross-section of the spiral block is "C"-shaped. This structural design can optimize airflow distribution, achieve more uniform bubble generation, and improve aeration efficiency.

[0007] According to the applicable sewage treatment air distribution and aeration device, a circular groove is formed at the bottom end of the first fixed column. A connecting pipe is rotatably connected to the groove, and the bottom end of the connecting pipe is fixedly connected to the second rotating column. This design facilitates the introduction and removal of airflow, ensuring stable operation of the aeration system.

[0008] According to the applicable sewage treatment air separation and aeration device, the top of the first fixed column is fixedly connected to an air inlet pipe, and the bottom end of the air inlet pipe is connected to the inside of the circular groove. This connection method is conducive to the smooth flow of air and improves the aeration effect.

[0009] According to the applicable sewage treatment air separation and aeration device, the top end of the first fixing column is fixedly connected to a fixing plate, and positioning holes are provided at both the upper and lower ends of the fixing plate. This design can ensure the stability and adjustability of the device.

[0010] According to the applicable sewage treatment air separation and aeration device, the number of the positioning holes is multiple, and a second bolt is slidably connected inside the positioning hole. The circumferential surface of the second bolt is threadedly connected to a hexagonal nut. This structural design facilitates installation and adjustment of the device and improves operational convenience.

[0011] According to the applicable sewage treatment air distribution aeration device, the number of the curved blades is six, each of which is provided with six diffusion tubes, and each of the diffusion tubes is provided with a plurality of diffusion holes. This design can increase the number of bubbles generated and their distribution uniformity, improve the oxygen transfer efficiency, and thus enhance the sewage treatment effect.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model is provided with arc-shaped fan blades, an air diffusion pipe and air diffusion holes. The design of the arc-shaped fan blades can distribute the air more evenly to the entire sewage treatment area. This uniform aeration helps to increase the solubility of oxygen in sewage, promote the activity of microorganisms, and thus improve the sewage treatment efficiency. The airflow generated when the arc-shaped fan blades rotate can effectively stir the sewage, so that pollutants such as suspended matter and organic matter are fully in contact with oxygen, accelerating the decomposition process. The air diffusion holes on the air diffusion pipe can decompose the air into smaller bubbles. These small bubbles can more easily penetrate the suspended matter in the sewage, thereby improving the utilization rate of oxygen.
