Description

Technical Field

[0001] This utility model relates to the field of aeration tank technology, and in particular to a uniform aeration device for a sewage treatment aeration tank. Background Technology

[0002] An aeration tank is a device for wastewater treatment using the activated sludge process. By blowing air or oxygen into the tank, it provides aerobic microorganisms with the oxygen needed to survive and decompose organic matter, enabling the microorganisms to multiply in large numbers and decompose organic pollutants in wastewater into harmless substances such as carbon dioxide and water, thereby achieving the purpose of purifying wastewater.

[0003] Currently, existing aeration tanks typically install aeration devices at the bottom of the tank, with aeration occurring through aeration holes in the pipes of the aeration devices. When the aeration tank is large or deep, the aeration generated by the aeration devices is difficult to cover the entire tank, resulting in a reduced aeration rate. This leads to insufficient oxygen for microorganisms far from the aeration discs, and also reduces the wastewater treatment capacity of the device, increasing the pressure on the wastewater treatment system. To address these issues, we propose a uniform aeration device for wastewater treatment aeration tanks. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a uniform aeration device for wastewater treatment aeration tanks.

An aeration pipe is provided at the bottom of the aeration tank body, and a connecting pipe is connected to the side of the aeration pipe. The connecting pipe is inserted into the inner wall of the aeration tank body. A support rod is provided at the top of the aeration tank body, and the bottom end of the support rod is connected to a protective cover. A motor is installed inside the protective cover, and first rotating shafts are symmetrically connected to both ends of the motor.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A uniform aeration device for a sewage treatment aeration tank includes an aeration tank body 1. An aeration pipe 2 is provided at the bottom of the aeration tank body 1, and a connecting pipe 3 is connected to the side of the aeration pipe 2. The working principle and connection method of the aeration pipe 2 and the connecting pipe 3 are existing technologies and will not be described in detail here. The connecting pipe 3 is inserted into the inner wall of the aeration tank body 1. A support rod 4 is provided at the top of the aeration tank body 1, and the bottom end of the support rod 4 is connected to a protective cover 5. The protective cover 5 is existing technology and can drive two sets of first rotating shafts 7 to rotate simultaneously. A motor 6 is installed inside the protective cover 5, and the two ends of the motor 6 are symmetrically connected to the first rotating shafts 7. A connecting sleeve 8 is sleeved on the outside of the first rotating shafts 7, and a stirring plate 9 is connected to the side of the connecting sleeve 8.

[0024] Furthermore, refer to Figure 2 , Figure 3 and Figure 4 It can be seen that the aeration tank body 1 is equipped with a second rotating shaft 10 inside, and the end of the second rotating shaft 10 and the end of the first rotating shaft 7 are respectively connected to a connecting plate 11. The two sets of connecting plates 11 are connected by a linkage belt 12. There are two sets of connecting sleeves 8. One set of connecting sleeves 8 is movably sleeved on the outside of the first rotating shaft 7, while the other set of connecting sleeves 8 is sleeved on the outer wall of the second rotating shaft 10. The linkage belt 12 consists of two sets of pulleys and one belt. The two sets of pulleys are respectively sleeved on the outside of the two connecting plates 11. Through the setting of the belt, the first rotating shaft 7 and the second rotating shaft 10 can rotate together, so that more stirring plates 9 can rotate together to ensure sufficient mixing of sewage.

[0025] Furthermore, refer to Figure 2 and Figure 4 It can be seen that the support rod 4 is set with an L-shaped structure. The top of the support rod 4 is connected to the aeration tank body 1 by bolts. During use, the support rod 4 with its L-shaped structure and bolts makes it easy for staff to remove the protective cover 5 together with the first rotating shaft 7 and the second rotating shaft 10 from the inside of the aeration tank body 1 for maintenance.

[0026] Furthermore, refer to Figure 2 and Figure 4 It can be seen that a protective frame 13 is fitted on the outer side of the linkage belt 12, and the end of the protective frame 13 abuts against the inner wall of the aeration tank body 1. The interior of the protective frame 13 is provided with holes that are compatible with the second rotating shaft 10. By covering the linkage belt 12 with the protective frame 13, the linkage belt 12 can be protected, thereby effectively preventing impurities from affecting the normal transmission of the linkage belt 12. Since the protective frame 13 abuts against the inner wall of the aeration tank body 1, it will not affect the removal requirements of the first rotating shaft 7 and the second rotating shaft 10. Furthermore, the connecting plate 11 is inserted into the interior of the protective frame 13 through a bearing, thereby not affecting the normal rotation of the first rotating shaft 7 and the second rotating shaft 10.

[0027] Furthermore, refer to Figure 3 It can be seen that a cylinder 15 is provided on the side of the connecting plate 11, and a fixing block 14 is connected to the end of the cylinder 15. The fixing block 14 is connected to the outer wall of the connecting sleeve 8. The cylinder 15 has the telescopic principle, which is existing technology. By starting the cylinder 15, the connecting sleeve 8 and the stirring plate 9 can be driven to move laterally, thereby increasing the contact area between the stirring plate 9 and the sewage, so as to effectively ensure the stirring effect of the stirring plate 9 on the sewage. Since the cylinder 15 is connected to the connecting plate 11, the cylinder 15 can rotate together with the connecting plate 11.

[0028] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the side of the connecting sleeve 8 is connected to two sets of fixing blocks 14, and the interior of the other set of fixing blocks 14 is provided with a guide rod 16, and the end of the guide rod 16 is connected to the connecting plate 11. Through the guidance of the guide rod 16, the stable lateral movement of the connecting sleeve 8 can be ensured. One end of the guide rod 16 provided on the outside of the first rotating shaft 7 is rotatably connected to the protective frame 13, and its other end maintains a certain distance from the outer wall of the protective cover 5, so as not to affect the normal rotation of the guide rod 16 with the connecting plate 11.

[0029] Furthermore, refer to Figure 2 It can be seen that the stirring plate 9 is designed as a long strip structure, and the interior of the stirring plate 9 is evenly provided with holes, which are not shown in the figure. Through the holes opened inside the stirring plate 9, the resistance when the stirring plate 9 rotates can be reduced, so as to ensure the stirring effect of the stirring plate 9 on the sewage.

[0030] Working Principle: When using this utility model, the operator can first connect the corresponding pipes and connecting pipes 3, and inject sewage into the aeration tank body 1. By setting aeration pipes 2 inside the aeration tank body 1, sewage treatment can be achieved. During the sewage treatment process, the motor 6 set inside the protective cover 5 is started to drive the two sets of first rotating shafts 7 to rotate continuously. With the connecting discs 11 and linkage belts 12 set at the ends of the first rotating shafts 7, the second rotating shaft 10 can be driven to rotate simultaneously. Since the connecting sleeves 8 are respectively sleeved on the outside of the second rotating shaft 10 and the first rotating shaft 7, and the stirring plates 9 are connected to the outside of the connecting sleeves 8, the stirring plates 9 can rotate continuously and stir the sewage inside the aeration tank body 1. The cylinder 15 set at the end of the connecting disc 11 can drive the connecting sleeves 8 to move laterally, thereby increasing the contact area between the stirring plates 9 and the sewage, and allowing the aeration generated by the aeration pipes 2 to fill the entire aeration tank body 1, thus effectively improving the sewage treatment effect of this device. The above is the complete working principle of this utility model.

[0031] In this utility model, the installation, connection or setting methods of all the components mentioned above are common mechanical methods, and the specific structure, model and coefficient index of all the components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
