Description

Technical Field

[0001] This application relates to the field of wastewater treatment, specifically to an aeration device for wastewater treatment. Background Technology

[0002] Wastewater treatment aeration devices are core equipment that inject air or oxygen into wastewater, utilizing the biochemical action of microorganisms to degrade organic pollutants. Their structure typically includes microporous aeration heads, diffusers, and a supporting blower system. By generating tiny bubbles, they increase the gas-liquid contact area, raising the dissolved oxygen concentration in the water and activating aerobic bacteria. Traditional aeration devices, such as disc and tubular aerators, can achieve basic functions, but during long-term operation, factors such as wastewater impurity deposition and excessive microbial biofilm growth can cause aeration hole blockage, leading to decreased aeration efficiency or even complete failure. This necessitates interrupting the wastewater treatment process for manual sludge removal or component replacement, increasing maintenance costs and severely restricting the continuity and treatment capacity of the wastewater treatment system due to frequent shutdowns. This is especially problematic when dealing with high-load wastewater, potentially leading to extended treatment cycles and fluctuations in effluent quality.

[0003] Therefore, in order to solve the above problems, this application provides an aeration device for sewage treatment that can simultaneously clean the aeration heads during daily use to prevent clogging of the aeration holes. Utility Model Content

[0004] The purpose of this invention is to provide an aeration device for wastewater treatment, which aims to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an aeration device for sewage treatment, comprising an air inlet pipe, which is placed at the bottom of an aeration tank, and an aeration head is connected to the upper end of the air inlet pipe. The aeration head and the air inlet pipe are connected to each other through a connecting column. An anti-clogging mechanism for rotating and brushing the aeration head is rotatably installed inside the air inlet pipe.

[0006] The anti-clogging mechanism includes a turbine, a universal joint, a rotating disk, and a brush head. The turbine is rotatably connected to the inner wall of the intake pipe. The rear end of the turbine is inserted into the universal joint. The end of the universal joint away from the turbine is inserted into the middle of the rotating disk. The rotating disk is rotatably connected to the connecting post and extends to the outside of the connecting post. The lower end of the brush head is engaged with the eccentric position of the upper end of the rotating disk.

[0007] The gas in the air inlet pipe enters the aeration head through the connecting column for aeration. The gas flows in the air inlet pipe and drives the turbine to rotate. The rotation of the turbine drives the rotating disk to rotate through the universal joint. The rotation of the rotating disk drives the brush head to rotate and continuously contact and rub against the aeration head.

[0008] By incorporating an anti-clogging mechanism, the airflow generated within the air inlet pipe drives the turbine to rotate. This, in turn, causes the brush head to rotate and clean the aeration head simultaneously during aeration. This effectively prevents clogging caused by sediment and disrupts the water around the aeration head, making the bubbles disperse more chaotically and enhancing their integration with the water. This significantly reduces downtime for maintenance due to clogging, allowing for easy cleaning during daily use, improving wastewater treatment efficiency, and further enhancing the aeration integration effect.

[0009] Furthermore, the air inlet pipes are interconnected and arranged in an S-shape at the bottom of the aeration tank. Multiple sets of aeration heads and anti-clogging mechanisms are provided, evenly distributed along the air inlet pipes. The aeration heads are cylindrical aeration stones, with micro-aeration holes evenly distributed around their perimeter. The rotating connection between the rotating disc and the connecting column is equipped with a rotating seal to prevent water from entering the interior of the connecting column.

[0010] Furthermore, an array of air vents is provided around the center of the rotating disc to prevent gas from failing to enter the aeration head through the connecting column. A rotating ring is fixedly connected to the outer circumference of the turbine, and the turbine is rotatably connected to the inner wall of the air inlet pipe through the rotating ring. The end of the air inlet pipe extends to the outside of the aeration tank, and an air pump is installed at the end of the air inlet pipe to pump gas into the air inlet pipe and form an airflow.

[0011] Furthermore, a connecting rod is inserted into the upper end of the aerator head, and the end of the connecting rod away from the aerator head is inserted into the upper end of the air inlet pipe.

[0012] Compared with existing technologies, it has the following beneficial effects:

[0013] This utility model provides an aeration device for sewage treatment. Through the setting of an anti-clogging mechanism, the airflow formed by the gas in the air inlet pipe causes the turbine to rotate. This causes the aeration head to rotate while performing aeration, and the brush head is driven to clean the aeration head. This effectively prevents the aeration head from being blocked by sediment. At the same time, it disturbs the water around the aeration head, making the bubbles disperse more chaotically and enhancing their integration with the water. This effectively reduces downtime maintenance caused by aeration head blockage, allows for cleaning during daily use, improves sewage treatment efficiency, and further enhances the aeration integration effect.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 As shown, the present invention provides the following technical solution: an aeration device for sewage treatment; including an air inlet pipe 1, which is placed at the bottom of the aeration tank, and an aeration head 2 is connected to the upper end of the air inlet pipe 1. The aeration head 2 and the air inlet pipe 1 are connected to each other through a connecting column 3. An anti-clogging mechanism 4 for rotating and brushing the aeration head 2 is rotatably installed inside the air inlet pipe 1.

[0021] The anti-clogging mechanism 4 includes a turbine 41, a universal joint 42, a rotating disk 43, and a brush head 44. The turbine 41 is rotatably connected to the inner wall of the intake pipe 1. The rear end of the turbine 41 is inserted into the universal joint 42. The end of the universal joint 42 away from the turbine 41 is inserted into the middle of the rotating disk 43. The rotating disk 43 is rotatably connected to the connecting post 3 and extends to the outside of the connecting post 3. The lower end of the brush head 44 is engaged with the eccentric position of the upper end of the rotating disk 43.

[0022] The gas in the air inlet pipe 1 enters the aeration head 2 through the connecting column 3 for aeration. The gas drives the turbine 41 to rotate as it flows in the air inlet pipe 1. The rotation of the turbine 41 drives the rotating disk 43 to rotate through the universal joint 42. The rotation of the rotating disk 43 drives the brush head 44 to rotate and continuously contact and rub against the aeration head 2.

[0023] Among them, the air inlet pipes 1 are spliced ​​together and arranged in an S-shape at the bottom of the aeration tank. The air inlet pipes 1 can be installed at the bottom of the aeration tank through the pre-arranged mounting bases. The air inlet pipes 1 are interconnected, so that the gas forms an airflow in the air inlet pipe 1 and finally enters the aeration head 2 for aeration operation.

[0024] Furthermore, multiple sets of aeration heads 2 and anti-clogging mechanisms 4 are provided, which are evenly arranged along the air inlet pipe 1. The multiple sets of aeration heads 2 continuously aerate at multiple positions at the bottom of the aeration tank to prevent uneven oxygen dissolution and ensure that the overall dissolved oxygen concentration of the aeration tank is at a relatively uniform level.

[0025] See Figure 3 The aeration head 2 is a cylindrical aeration stone, with micro-aeration holes 21 evenly arranged around its perimeter. Compared to traditional disc aeration, the cylindrical aeration stone design makes it less likely for sediments in the water to accumulate or settle within the aeration holes, thus reducing the likelihood of clogging. However, during aeration, the bubbles formed by the side aeration holes tend to merge more easily as they rise, forming larger bubbles and reducing their solubility in the water. By using a rotating brush head 44 to agitate the water around the aeration head 2, the bubbles undergo more complex movements, making them less likely to merge. This prevents clogging of the aeration holes and reduces the decrease in solubility caused by the cylindrical aeration stone.

[0026] It should be noted that the rotating connection between the rotating disk 43 and the connecting column 3 is equipped with a rotating seal to prevent water from entering the interior of the connecting column 3.

[0027] As another embodiment, such as Figures 2 to 4 As shown, the rotating disk 43 has a series of vent holes 431 on its central circumference, allowing gas to enter the aeration head 2 through the connecting column 3. When the gas flows in the air inlet pipe 1, it drives the turbine 41 to rotate, and then enters the aeration head 2 through the connecting column 3 and the vent holes 431 for aeration. The rotating turbine 41 drives the universal joint 42 at its rear end to rotate, which in turn drives the rotating disk 43 to rotate. During this rotation, the rotating disk 43 drives the brush head 44 to perform a circular motion, which in turn brushes the side of the aeration head 2 to prevent the micro-aeration holes 21 from becoming clogged.

[0028] See Figure 2 A rotating ring 411 is fixedly connected to the outer periphery of the turbine 41. The turbine 41 is rotatably connected to the inner wall of the intake pipe 1 through the rotating ring 411. The rotating ring 411 is rotatably connected to the inner wall of the intake pipe 1.

[0029] It should be noted that the end of the air inlet pipe 1 extends to the outside of the aeration tank, and an air pump is installed at the end of the air inlet pipe 1 to pump gas into the air inlet pipe 1 and form an airflow.

[0030] See Figure 2 as well as Figure 3A connecting rod 22 is inserted into the upper end of the aeration head 2. The end of the connecting rod 22 away from the aeration head 2 is inserted into the upper end of the air inlet pipe 1. Since the rotating disk 43 is set to partially separate the connecting column 3, in order to prevent the connecting column 3 above from rotating during the rotation of the rotating disk 43, the upper end of the aeration head 2 is connected to the air inlet pipe 1 by the connecting rod 22 to prevent it from rotating. This fixes the connecting column 3 and the aeration head 2, thereby enhancing the stability of the device operation.

[0031] Working principle: During use, the air pump pumps the gas into the air inlet pipe 1 to form an airflow. When the gas flows in the air inlet pipe 1, it drives the turbine 41 to rotate. Then, it enters the aeration head 2 through the connecting column 3 and the air vent 431 for aeration. The rotating turbine 41 drives the universal joint 42 at its rear end to rotate. The rotation of the universal joint 42 drives the rotating disk 43 to rotate. The rotating disk 43 drives the brush head 44 to perform a circular motion. The brush head 44 then brushes the side of the aeration head 2 to prevent the micro aeration holes 21 from becoming blocked.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
