Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment uninterrupted replacement aeration device. Background Technology

[0002] In wastewater treatment aeration processes, the aeration efficiency, stability, and ease of maintenance of aeration devices directly affect the wastewater treatment effect.

[0003] Current aeration devices are all installed directly at the bottom of the sewage, operating through multiple aeration holes. However, the following problems exist during the aeration process:

[0004] 1. The aeration holes are prone to clogging. The aeration holes of the existing aeration devices are immersed in sewage for a long time. Suspended impurities and microorganisms in the sewage can easily adhere to and clog the aeration holes, resulting in a decrease in aeration efficiency. Frequent shutdowns, disassembly and cleaning are required, which increases maintenance costs.

[0005] 2. It cannot achieve uninterrupted aeration. When the aeration holes are blocked, the machine needs to be stopped for replacement or maintenance, which will interrupt the sewage treatment process and reduce the treatment efficiency. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the aeration holes are easy to be blocked and cannot achieve uninterrupted aeration. To this end, we propose a wastewater treatment uninterrupted replacement aeration device.

[0007] To achieve the above objectives, this application adopts the following technical solution: a wastewater treatment uninterrupted replacement aeration device, comprising two parallel first pipes, with multiple air inlet frames fixedly connected between the inner walls of the two first pipes, and each of the multiple air inlet frames is provided with an aeration mechanism.

[0008] The aeration mechanism includes multiple rigid tubes that are rotatably connected to the top of the air inlet frame through a sealing connection. The upper ends of the multiple rigid tubes are fixedly connected to a horizontally arranged hollow disc. Two aeration zones are symmetrically arranged on the multiple hollow discs. Each of the two aeration zones includes multiple aeration holes opened in the top of the hollow disc. The two aeration zones achieve alternating aeration through the rotation of the hollow discs with the rigid tubes, ensuring that the aeration process is uninterrupted.

[0009] Each of the hollow discs is equipped with a dredging mechanism, which includes two sector plates. The lower ends of the two sector plates are elastically connected to the bottom of the hollow disc through multiple springs, and multiple dredging rods are fixedly connected to the upper ends of the two sector plates.

[0010] Preferably, the multiple unblocking rods on the two fan-shaped plates correspond one-to-one with the multiple aeration holes on the two aeration zones.

[0011] Preferably, two rectangular rods are slidably connected through the bottom of the hollow disk, the lower ends of the two sector plates are fixedly connected to the upper ends of the two rectangular rods respectively, and the lower ends of the two rectangular rods are fixedly connected to a first convex plate. The upper end of the air intake frame near the rigid tube is fixedly connected to a second convex plate, and the two first convex plates intermittently fit against the side wall of the second convex plate during rotation.

[0012] Preferably, the sidewall of the air intake frame is fixedly connected to a plurality of fixing plates corresponding one-to-one with a plurality of rigid tubes, and a waterproof motor is fixedly connected to the lower end of each of the plurality of fixing plates. A first wheel is fixedly connected to the sidewall of the output shaft of each of the plurality of waterproof motors, and a second wheel is fixedly connected to the sidewall of each of the plurality of rigid tubes. A synchronous belt connects the first wheel and its corresponding second wheel.

[0013] Preferably, the aeration mechanism further includes two second pipes, the bottom of each of the two second pipes is fixedly connected to two third pipes, and the lower ends of the four third pipes are respectively fixedly connected to the top of the two first pipes.

[0014] Preferably, the upper ends of the two second tubes are fixedly connected with hanging rods for suspension installation, and reinforcing support rods are fixedly connected between the opposite sidewalls of the two first tubes, between the opposite sidewalls of the two second tubes, and between the adjacent sidewalls of the four third tubes to improve the overall structural stability of the device.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] In this invention, the waterproof motor rotates, which drives the rigid pipe to rotate via the first wheel, the synchronous belt, and the second wheel. This, in turn, drives the hollow disc to rotate, causing tiny bubbles flowing out from multiple aeration holes to rise in a spiral shape along with the rotation of the hollow disc, thereby increasing the dissolved oxygen level in the wastewater.

[0017] In this invention, the two first convex plates intermittently contact the side wall of the second convex plate during rotation. Through the blocking and pushing force of the second convex plate and the elastic force of multiple springs, the two first convex plates drive the two fan-shaped plates to move up and down alternately through two rectangular rods. This enables multiple unblocking rods to alternately unblock multiple aeration holes in the two aeration zones, preventing the aeration holes from becoming easily blocked, which would require shutdown for maintenance, prevent uninterrupted aeration, and reduce wastewater treatment efficiency.

[0027] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0028] Reference Figures 1-7 As shown, this utility model provides a technical solution: a wastewater treatment uninterrupted replacement aeration device, comprising two parallel first pipes 1, with multiple air inlet frames 2 (such as...) fixedly connected between the inner walls of the two first pipes 1. Figure 2 (As shown).

[0029] Each of the multiple air intake frames 2 is equipped with an aeration mechanism. The aeration mechanism includes multiple rigid tubes 3 that are rotatably connected to the top of the air intake frame 2 through a sealing connection. The upper ends of the multiple rigid tubes 3 are fixedly connected to a horizontally arranged hollow disc 4. Each of the multiple hollow discs 4 has two aeration zones symmetrically arranged. Each of the two aeration zones includes multiple aeration holes 5 opened in the top of the hollow disc 4. The two aeration zones achieve alternating aeration through the rotation of the hollow disc 4 with the rigid tubes 3, ensuring that the aeration process is uninterrupted.

[0030] The aeration mechanism also includes two second pipes 16, and the bottom of each of the two second pipes 16 is fixedly connected to two third pipes 17. The lower ends of the four third pipes 17 are respectively fixedly connected to the top of the two first pipes 1.

[0031] The upper ends of both second pipes 16 are fixedly connected to hanging rods 18 for suspending the device in sewage. Reinforcing support rods 19 are fixedly connected between the opposite sidewalls of the two first pipes 1, between the opposite sidewalls of the two second pipes 16, and between the adjacent sidewalls of the four third pipes 17. Figure 1 (As shown), used to improve the overall structural stability of the device.

[0032] Furthermore, the two second pipes 16 are equipped with threaded fittings for connection to the output pipe of an external air pump. This connection method is existing technology. The external air pump then pumps air into the two second pipes 16. Subsequently, the gas enters the two first pipes 1 through four third pipes 17, and then enters the multiple hollow discs 4 through multiple air inlet frames 2 and multiple rigid pipes 3. Finally, it forms microbubbles through multiple aeration holes 5 and is injected into the sewage. During the rise of the bubbles, oxygen diffuses into the sewage, providing oxygen for the aerobic microorganisms in the sewage to maintain their activity, while promoting the oxidation and decomposition of organic matter and keeping the activated sludge in suspension, thereby improving the sewage treatment effect.

[0033] The side wall of the air intake frame 2 is fixedly connected to multiple fixing plates 12, which correspond one-to-one with multiple rigid tubes 3. The lower end of each fixing plate 12 is fixedly connected to a waterproof motor 13. The side wall of the output shaft of each waterproof motor 13 is fixedly connected to a first wheel 14. The side wall of each rigid tube 3 is fixedly connected to a second wheel 15. A synchronous belt connects the first wheel 14 and its corresponding second wheel 15.

[0034] During aeration, the waterproof motor 13 is driven to rotate, which in turn drives the rigid pipe 3 to rotate via the first wheel 14, the synchronous belt, and the second wheel 15. This causes the hollow disc 4 to rotate, resulting in tiny bubbles flowing out from multiple aeration holes 5 rising in a spiral shape along with the rotation of the hollow disc 4, thereby increasing the dissolved oxygen in the wastewater.

[0035] It should be noted that the waterproof motor 13 is a YQS series three-phase asynchronous motor with an IP68 protection rating, which is suitable for the humid and corrosive working conditions of sewage treatment.

[0036] Each of the multiple hollow discs 4 is equipped with a dredging mechanism, which includes two fan-shaped plates 7. The lower ends of the two fan-shaped plates 7 are elastically connected to the bottom of the hollow disc 4 through multiple springs 6. The upper ends of the two fan-shaped plates 7 are fixedly connected with multiple dredging rods 8.

[0037] The multiple unblocking rods 8 on the two fan-shaped plates 7 correspond one-to-one with the multiple aeration holes 5 on the two aeration zones.

[0038] Two rectangular rods 9 are slidably connected through the bottom of the hollow disk 4. The lower ends of the two sector plates 7 are fixedly connected to the upper ends of the two rectangular rods 9 respectively. The lower ends of the two rectangular rods 9 are fixedly connected to the first convex plate 10. The upper end of the air intake frame 2 near the rigid tube 3 is fixedly connected to the second convex plate 11. The two first convex plates 10 intermittently fit against the side wall of the second convex plate 11 during rotation. It should be noted that the first convex plate 10 and the second convex plate 11 are both arc-shaped, and the arc centers of the first convex plate 10 and the second convex plate 11 coincide with the center of the hollow disk 4.

[0039] The hollow disc 4 rotates, and the two rectangular rods 9 and the two first convex plates 10 rotate. During this rotation, the two first convex plates 10 intermittently contact the side wall of the second convex plate 11. Through the blocking and pushing force of the second convex plate 11 and the elastic force of multiple springs 6, the two first convex plates 10 drive the two fan-shaped plates 7 to move up and down alternately through the two rectangular rods 9. This allows multiple unblocking rods 8 to alternately unblock the multiple aeration holes 5 in the two aeration zones, preventing the aeration holes 5 from being easily blocked, which would require shutdown for treatment, prevent uninterrupted aeration, and reduce the efficiency of sewage treatment.

[0040] Furthermore, such as Figure 4 , Figure 6 and Figure 7 As shown, when one of the first convex plates 10 and the second convex plate 11 are in contact, the fan-shaped plate 7 and the multiple unblocking rods 8 corresponding to the first convex plate 10 move upward to unblock the multiple aeration holes 5. At this time, the other first convex plate 10 moves away from the second convex plate 11, and the fan-shaped plate 7 and the multiple unblocking rods 8 corresponding to the first convex plate 10 move downward to the initial position, so as to realize uninterrupted aeration of sewage.

[0041] Working principle: The user places the device in the sewage using an external crane and hanging rod 18. Then, the threaded fittings on the two second pipes 16 are connected to the output pipe of the external air pump. The external air pump then pumps air into the two second pipes 16. The gas then enters the two first pipes 1 through four third pipes 17, and then enters the multiple hollow discs 4 through multiple air inlet frames 2 and multiple rigid pipes 3. Finally, it forms microbubbles through multiple aeration holes 5 and is injected into the sewage. As the bubbles rise, oxygen diffuses into the sewage, providing oxygen for the aerobic microorganisms in the sewage to maintain their activity, while promoting the oxidation and decomposition of organic matter and keeping the activated sludge in suspension, thus improving the sewage treatment effect.

[0042] During the aeration process, the waterproof motor 13 is driven to rotate, which drives the rigid pipe 3 to rotate through the first wheel 14, the synchronous belt and the second wheel 15, which in turn drives the hollow disc 4 to rotate. This causes the tiny bubbles flowing out from multiple aeration holes 5 to rise in a spiral shape along with the rotation of the hollow disc 4, thereby increasing the dissolved oxygen in the wastewater.

[0043] Simultaneously, the hollow disc 4 rotates, along with the two rectangular rods 9 and the two first convex plates 10. During this rotation, the two first convex plates 10 intermittently contact the sidewall of the second convex plate 11. Through the blocking force of the second convex plate 11 and the elastic force of multiple springs 6, the two first convex plates 10 alternately drive the two sector plates 7 to move up and down via the two rectangular rods 9. When one of the first convex plates 10 contacts the second convex plate 11, the sector plate 7 corresponding to that first convex plate 10 and multiple unblocking rods 8 move upward to unblock multiple aeration holes 5. At the same time, the other first convex plate 10 moves away from the second convex plate 11, and the sector plate 7 corresponding to that first convex plate 10 and multiple unblocking rods 8 move downward to their initial positions. This allows multiple unblocking rods 8 to alternately unblock multiple aeration holes 5 in the two aeration zones, achieving uninterrupted aeration of the sewage and preventing the aeration holes 5 from easily clogging, which would require shutdown and prevent uninterrupted aeration, thus reducing sewage treatment efficiency.

[0044] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
