Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an aeration mechanism for wastewater treatment in ecological environment governance. Background Technology

[0002] An aeration system is a device system used in wastewater treatment to increase dissolved oxygen levels in water by supplying air or oxygen, thereby promoting the growth, reproduction, and metabolism of microorganisms, enhancing the water's self-purification capacity, and ultimately improving water quality and degrading pollutants. Existing equipment typically includes a stirring device to ensure that oxygen is evenly distributed in the water, improving the contact efficiency between the gas and water.

[0003] However, the mixing blades of traditional aeration mechanisms are usually designed with a fixed angle, which cannot be dynamically adjusted according to the viscosity of the wastewater. When treating high-viscosity wastewater, the fixed-angle blades are prone to causing equipment overload due to excessive resistance, while the mixing effect is poor; while when treating low-viscosity wastewater, the fixed angle may result in energy waste. Utility Model Content

[0004] To address the problems mentioned above in the background art, this utility model provides an aeration mechanism for sewage treatment in ecological environment governance.

[0005] The solution adopted by this utility model to solve its technical problem is: an aeration mechanism for sewage treatment in ecological environment management, comprising: A pool body for containing wastewater to be treated; An aeration component is disposed in the tank body to increase the oxygen content inside the tank body; A stirring assembly is disposed inside the tank body. The stirring assembly includes a stirring shaft, a first driving component drivenly connected to the stirring shaft, and a plurality of stirring blades uniformly disposed on the stirring shaft. The stirring shaft has a displacement cavity inside. An adjustment assembly includes a movable rod movably disposed in the displacement cavity and a second driving member drivenly connected to the movable rod. One end of the stirring blade is hinged to the movable rod. The second driving member can drive the movable rod to move axially along the displacement cavity, thereby adjusting the angle of the stirring blade. The control system is electrically connected to the second drive component and is used to detect the viscosity of wastewater and output a control signal.

[0006] Furthermore, the control system includes: A viscosity sensor, used to detect the viscosity of wastewater in the tank; A controller is used to receive sensor data and calculate the optimal tilt angle of the stirring blades.

[0007] Furthermore, the hinge point between the movable rod and the stirring blade is provided with a fisheye bearing, which allows the stirring blade to swing freely around its fixed point.

[0008] Furthermore, the first driving component is a variable frequency motor, and it is electrically connected to the control system.

[0009] Furthermore, the aeration assembly includes: Oxygen pump; An air supply pipeline is connected to the oxygen supply pump and is buried under the pool body; Multiple microporous aeration discs are provided, all of which are connected to the air supply pipeline.

[0010] Furthermore, each of the microporous aeration discs is provided with a swirl guide plate on its surface.

[0011] In summary, the beneficial effects of this invention are as follows: By installing a viscosity sensor inside the tank, this invention can monitor the viscosity of wastewater in real time. Based on the detection results, the controller automatically adjusts the angle of the stirring blades through an adjustment component to adapt to the treatment requirements of wastewater with different viscosities. For high-viscosity wastewater, the blade inclination angle can be increased to enhance shear force, break down viscous resistance, and promote mixing; for low-viscosity wastewater, the blade inclination angle can be reduced to lower energy consumption.

[0015] To make the content of this utility model easier to understand, the present utility model will be further described below with reference to specific embodiments and accompanying drawings.

Unless otherwise stated, "a plurality of" means two or more.

[0017] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] To address the problems in the background technology, this utility model proposes an aeration mechanism for wastewater treatment in ecological environment governance, comprising: Pool 1, which is used to contain wastewater to be treated; Aeration component 2, which is disposed inside the pool body 1, is used to increase the oxygen content inside the pool body 1; A stirring assembly 3 is disposed inside the tank body 1. The stirring assembly 3 includes a stirring shaft 31, a first driving member 32 drivenly connected to the stirring shaft 31, and a plurality of stirring blades 33 uniformly disposed on the stirring shaft 31. The stirring shaft 31 has a displacement cavity 311 inside. Adjustment component 4 includes a movable rod 41 movably disposed in the displacement cavity 311 and a second driving member 42 drivenly connected to the movable rod 41. One end of the stirring blade 33 is hinged to the movable rod 41. The second driving member 42 can drive the movable rod 41 to move axially along the displacement cavity 311, thereby adjusting the angle of the stirring blade 33. The control system is electrically connected to the second drive component 42 and is used to detect the viscosity of wastewater and output a control signal.

[0019] Combined with reference Figures 1 to 3As shown, in this embodiment, the tank 1 serves as the main structure of the entire wastewater treatment system, primarily used to contain the wastewater to be treated and provide the necessary space for the entire treatment process. Within this space, the wastewater undergoes agitation and aeration to ensure maximum treatment efficiency. The bottom or sidewalls of the tank 1 are equipped with installation interfaces for aeration components 2, facilitating the installation of aeration equipment, including air supply pipes and microporous aeration heads, to introduce air into the tank 1 and increase oxygen content. Sufficient oxygen is crucial for the growth and activity of aerobic microorganisms, helping to accelerate the degradation of organic matter in the wastewater, thereby improving the wastewater treatment effect.

[0020] In the middle section of the tank 1, one or more sets of stirring components 3 are provided for stirring the wastewater to be treated within the tank 1. Specifically, in this embodiment, the stirring component 3 includes a stirring shaft 31 spanning both sides of the tank 1 and a first driving member 32 that drives its rotation. The first driving member 32 can be an asynchronous motor with a reducer. Multiple stirring blades 33 are evenly distributed on the stirring shaft 31. When the first driving member 32 drives the stirring shaft 31 to rotate, the stirring shaft 31 drives the stirring blades 33 to fully stir the wastewater within the tank 1, thereby preventing the sedimentation of impurities in the wastewater and ensuring good contact between microorganisms and the wastewater. If multiple stirring components 3 are provided, the stirring blades 33 of adjacent stirring components 3 will be staggered to enhance the stirring effect.

[0021] In addition, a displacement cavity 311 is provided inside the stirring shaft 31, and a movable rod 41 driven by a second driving member 42 is installed inside the displacement cavity 311. The displacement cavity 311 is an axial cavity that runs through the length of the stirring shaft 31, and its cross-sectional shape is usually circular or rectangular, matching the shape of the movable rod 41 and providing space for the axial movement of the movable rod 41. The movable rod 41 is nested inside the displacement cavity 311, and its length is slightly smaller than that of the displacement cavity 311, ensuring that it can move freely within the cavity. Driven by the second driving member 42 (such as an electric push rod or a hydraulic cylinder), the movable rod 41 moves axially along the displacement cavity 311. The root of each stirring blade 33 is connected to the movable rod 41 through a hinge point (such as a fisheye bearing 5), so that the main body of the stirring blade 33 can rotate freely around the root. When the movable rod 41 moves axially along the displacement cavity 311, it drives the stirring blade 33 to rotate around the root through the hinge point, thereby adjusting the tilt angle of the blade. Specifically, the second drive component 42 pushes the movable rod 41 upward along the displacement cavity 311, and pulls the upper end of the stirring blade 33 through the hinge point, causing the stirring blade 33 to rotate around its root, increasing the tilt angle (e.g., the angle with the horizontal plane increases from 30° to 45°). The increased blade tilt angle enhances the shear force and turbulence effect on the wastewater, making it suitable for high-viscosity wastewater conditions. Similarly, the second drive component 42 pulls the movable rod 41 downward along the displacement cavity 311, which pushes the upper end of the stirring blade 33 through the hinge point, causing the stirring blade 33 to rotate around its root, decreasing the tilt angle (e.g., the angle with the horizontal plane decreases from 45° to 15°). The reduced tilt angle of the stirring blade 33 lowers the stirring resistance, making it suitable for low-viscosity wastewater conditions. The control system is electrically connected to the second drive component 42, capable of detecting the viscosity of the wastewater and outputting control signals based on the detection results. This automatically adjusts the action of the second drive component 42, thereby precisely controlling the movement of the movable rod 41 and adjusting the angle of the stirring blade 33. It enables dynamic matching of the mixing effect with the viscosity of the wastewater, avoiding the problems of over-mixing or under-mixing.

[0022] In one possible implementation, the control system includes: A viscosity sensor, used to detect the viscosity of wastewater in tank 1; A controller is used to receive sensor data and calculate the optimal tilt angle of the stirring blades 33.

[0023] In this embodiment, the viscosity sensor includes, but is not limited to, an online rotational viscometer, a vibrational viscosity sensor, or an ultrasonic viscosity sensor. It is installed inside or at the bottom of the tank body 1 to ensure sufficient contact between the sensor probe and the wastewater. This embodiment employs multiple sensors distributed throughout the tank body 1 to improve detection accuracy. Each sensor transmits the detected viscosity data to the controller as an electrical signal. After receiving the data, the controller calculates the optimal tilt angle of the stirring blade 33 and outputs a control signal to the second drive component 42, causing it to drive the movable rod 41 to move, thereby adjusting the angle of the stirring blade 33.

[0024] Furthermore, a fisheye bearing 5 is provided at the hinge point between the movable rod 41 and the stirring blade 33, the fisheye bearing 5 being used to allow the stirring blade 33 to swing freely around its fixed point.

[0025] Furthermore, the first drive component 32 is a variable frequency motor and is electrically connected to the control system. Specifically, the control system adjusts the operating frequency of the variable frequency motor based on data from the viscosity sensor, thereby controlling the rotational speed and stirring intensity of the stirring blades 33 in real time. The stirring force is automatically adjusted according to the viscosity of the wastewater to ensure optimal stirring effect.

[0026] Furthermore, the aeration component 2 includes: Oxygen pump 21; Gas transmission pipeline 22, which is connected to the oxygen supply pump 21 and is buried under the pool body 1; Microporous aeration discs 23 are provided in multiple forms, all of which are connected to the air supply pipe 22.

[0027] Combined with reference Figure 1As shown, in this embodiment, the main function of the oxygen pump 21 is to compress and deliver air or oxygen to the aeration system. It provides sufficient pressure and flow rate to efficiently deliver air to the pool or wastewater treatment tank, thereby increasing the dissolved oxygen content in the water. Increasing dissolved oxygen promotes the growth and metabolism of microorganisms in the water, thus achieving the goal of wastewater treatment or water quality improvement. The oxygen pump 21 is connected to the microporous aeration disc 23 via an air delivery pipe 22, responsible for delivering gas to the bottom of the tank 1. The air delivery pipe 22 is typically buried at the bottom of the tank 1 to ensure that the gas delivery process does not interfere with surface activity and can efficiently deliver oxygen to the bottom of the water. To prevent gas leakage and ensure smooth gas delivery, the air delivery pipe 22 typically has high sealing and corrosion resistance. The microporous aeration disc 23, as a key component of the aeration system, has multiple tiny pores (typically 0.2 mm to 2 mm in diameter) arranged on its surface. Through these pores, the gas is uniformly dispersed into fine bubbles. When gas passes through the microporous aeration disc 23, it generates a large number of tiny bubbles, which significantly increases the contact area between water and gas and improves the oxygen dissolution efficiency.

[0028] Furthermore, each of the microporous aeration discs 23 is provided with a swirling guide plate 6 on its surface. Specifically, the swirling guide plate 6 on the surface of the microporous aeration disc 23 can improve aeration efficiency and optimize gas distribution. It helps to generate a rotating airflow and form a swirling motion when the gas passes through the microporous aeration disc 23. This helps to evenly distribute the gas on the surface of the aeration disc, avoiding bubble aggregation or localized over-aeration, thereby improving the aeration effect and allowing the gas to better contact and exchange with the liquid.

[0029] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
