Description

Technical Field

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

[0002] Aeration refers to the artificial introduction of air into a biological aeration tank using appropriate equipment to achieve a desired purpose. Aeration not only brings oxygen into the tank by contacting the liquid with air, but also accelerates the transfer of oxygen from the air into the liquid due to the agitation of the liquid, thus achieving the purpose of oxygenation.

[0003] Most existing aeration devices have a fixed connection between the main aeration pipe and the auxiliary aeration pipe, which cannot be adapted and adjusted according to actual needs. This results in uneven aeration and failure to maximize utilization. Furthermore, when the aeration nozzle on the auxiliary aeration pipe is damaged, the entire aeration device needs to be replaced, increasing maintenance and replacement costs.

[0004] Therefore, we propose an aeration device for wastewater treatment. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an aeration device for wastewater treatment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An aeration device for wastewater treatment includes a main aeration pipe. A first connecting plate is fixedly installed on each of the two sides of the main aeration pipe. A clamping plate is connected to the first connecting plate through a base plate. A second connecting plate is provided on one side of the first connecting plate. A connecting block is fixedly installed on the second connecting plate. The connecting block is slidably connected to the clamping plate. An auxiliary aeration pipe is fixedly installed at the end of the second connecting plate away from the connecting block.

[0008] As a further embodiment of this utility model: a connecting pipe is fixedly installed at one end of the first connecting plate, the connecting pipe is connected to the main aeration pipe, the first connecting plate is fixedly connected to the bottom plate, and the bottom plate and the connecting pipe are located on the same plane.

[0009] As a further embodiment of this utility model: the number and position of the base plate and the connecting block correspond to each other, the base plate is rotatably connected to the clamping plate, and a horizontal plate is rotatably mounted on one side surface of the clamping plate.

[0010] As a further embodiment of this utility model: the horizontal plate is connected to the base plate by a spring, and a telescopic rod is fixedly installed between the base plate and the horizontal plate, with the telescopic rod located inside the spring.

[0011] As a further embodiment of this utility model: a connecting pipe is fixedly installed on one side surface of the second connecting plate, the connecting pipe is connected to the auxiliary aeration pipe, the connecting pipe and the connecting block are located on the same plane, and the connecting pipe and the connecting pipe are slidably connected.

[0012] As a further embodiment of this utility model: a plurality of main aeration nozzles are fixedly installed on the main aeration pipe, a plurality of auxiliary aeration nozzles are fixedly installed on the auxiliary aeration pipe, an air inlet pipe is fixedly installed at one end of the main aeration pipe, and the main aeration pipe is connected to the air inlet pipe.

[0013] As a further embodiment of this utility model: a connecting block is fixedly installed at the end of the main aeration pipe away from the air inlet pipe, an electric push rod is fixedly installed on the connecting block, and a weight-adding block is fixedly installed at the lower end of the electric push rod.

[0014] Compared with the prior art, the present invention provides an aeration device for sewage treatment, which has the following beneficial effects:

[0015] 1. In this utility model, when the operator needs to connect the auxiliary aeration pipe to the main aeration pipe, after aligning the connecting block with the clamping plate, the second connecting plate is pushed, which causes the connecting block to push the clamping plate to rotate. Thus, the connecting block is located between the two clamping plates, and the spring is provided so that the clamping plate remains in its original shape when there is no external force, thereby enabling the clamping plate to firmly hold the connecting block, thus making the main aeration pipe and the auxiliary aeration pipe firmly connected.

[0016] When the secondary aeration pipe needs to be disassembled and replaced, the staff will forcefully slide the No. 2 connecting plate away from the No. 1 connecting plate, so that the connecting block can slide out of the clamp, and then the main aeration pipe and the secondary aeration pipe will be separated.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0023] 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.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example: An aeration device for wastewater treatment, such as Figures 1-4As shown, the system includes a main aeration pipe 1. A connecting plate 9 is fixedly installed on each of the two sides of the main aeration pipe 1. A clamping plate 12 is connected to the connecting plate 9 via a base plate 11. A second connecting plate 10 is located on one side of the first connecting plate 9. A connecting block 16 is fixedly installed on the second connecting plate 10, and the connecting block 16 is slidably connected to the clamping plate 12. A secondary aeration pipe 2 is fixedly installed at the end of the second connecting plate 10 away from the connecting block 16. When the operator needs to connect the secondary aeration pipe 2 to the main aeration pipe 1, the connecting block 16 on the second connecting plate 10 is aligned with the clamping plate 12 on the first connecting plate 9, and the second connecting plate 10 is pushed. This causes the connecting block 16 to push against the clamping plate 12, causing the two clamping plates 12 to rotate. Thus, the connecting block 16 is positioned between the two clamping plates 12, and is connected to the base plate 11 via the clamping plate 12. The elastic device allows the clamping plate 12 to maintain its original shape when no external force is applied, thereby enabling the clamping plate 12 to firmly clamp the connecting block 16, thus ensuring a stable connection between the first connecting plate 9 and the second connecting plate 10. A connecting pipe 17 is fixedly installed at one end of the first connecting plate 9, and a connecting pipe 18 is fixedly installed on the second connecting plate 10. When the first connecting plate 9 and the second connecting plate 10 are slidably connected, the connecting pipe 17 and the connecting pipe 18 are also slidably connected, allowing the gas in the main aeration pipe 1 to enter the secondary aeration pipe 2. When the secondary aeration pipe 2 needs to be disassembled and replaced, the operator forcefully slides the second connecting plate 10 away from the first connecting plate 9, thereby causing the connecting block 16 to slide out of the clamping plate 12, and then the main aeration pipe 1 and the secondary aeration pipe 2 are separated.

[0026] like Figures 1-4 As shown, a connecting pipe 17 is fixedly installed at one end of the first connecting plate 9. The connecting pipe 17 is connected to the main aeration pipe 1. The first connecting plate 9 is fixedly connected to the bottom plate 11. The bottom plate 11 and the connecting pipe 17 are located on the same plane. The number and position of the bottom plate 11 and the connecting block 16 are corresponding. The bottom plate 11 is rotatably connected to the clamping plate 12. A horizontal plate 13 is rotatably mounted on one side surface of the clamping plate 12. By setting the connecting pipe 17 fixedly installed at one end of the first connecting plate 9 and connecting the connecting pipe 17 to the main aeration pipe 1, the gas in the main aeration pipe 1 can enter the connecting pipe 17. This facilitates the gas to be transmitted from the connecting pipe 17 to the connecting pipe 18 and enter the auxiliary aeration pipe 2 after the connecting pipe 17 is connected to the connecting pipe 18. By setting the bottom plate 11 and the clamping plate 12 to be rotatably connected, when the connecting block 16 squeezes the clamping plate 12, it drives the clamping plate 12 to rotate, thereby driving the horizontal plate 13 to press down.

[0027] like Figures 1-4As shown, the horizontal plate 13 is connected to the base plate 11 via a spring 15. A telescopic rod 14 is fixedly installed between the base plate 11 and the horizontal plate 13. The telescopic rod 14 is located inside the spring 15. A connecting pipe 18 is fixedly installed on one side surface of the second connecting plate 10. The connecting pipe 18 is connected to the auxiliary aeration pipe 2. The connecting pipe 18 and the connecting block 16 are located on the same plane. The connecting pipe 18 and the connecting pipe 17 are slidably connected. By setting the horizontal plate 13 to the base plate 11 via a spring 15, and the telescopic rod 14 fixedly installed between the base plate 11 and the horizontal plate 13, when the horizontal plate 13 is pressed down by the rotation of the clamping plate 12, the telescopic rod 14 is shortened. At this time, the spring 15 is in a compressed state. When the connecting block 16 is pressed down, the horizontal plate 13 is compressed. When 6 is completely inside the clamping plate 12, the elastic force of the spring 15 drives the telescopic rod 14 and the horizontal plate 13 to move upward, thereby resetting the clamping plate 12 and clamping the connecting block 16. Since a connecting pipe 18 is fixedly installed at one end of the second connecting plate 10, and the diameter of the connecting pipe 18 is larger than that of the connecting pipe 17, when the second connecting plate 10 and the first connecting plate 9 are slidably connected, the connecting pipe 17 and the connecting pipe 18 are slidably connected together. The connecting pipe 17 is connected to the main aeration pipe 1, and the connecting pipe 18 is connected to the auxiliary aeration pipe 2, so that the gas in the main aeration pipe 1 can enter the auxiliary aeration pipe 2 through the connecting pipe 17 and the connecting pipe 18.

[0028] like Figures 1-4 As shown, several main aeration nozzles 7 are fixedly installed on the main aeration pipe 1, and several auxiliary aeration nozzles 8 are fixedly installed on the auxiliary aeration pipe 2. An air inlet pipe 3 is fixedly installed at one end of the main aeration pipe 1, and the main aeration pipe 1 is connected to the air inlet pipe 3. A connecting block 4 is fixedly installed at the end of the main aeration pipe 1 away from the air inlet pipe 3. An electric push rod 5 is fixedly installed on the connecting block 4, and a weighting block 6 is fixedly installed at the lower end of the electric push rod 5. By setting the main aeration nozzles 7 and auxiliary aeration nozzles 8, the gas in the main aeration pipe 1 is output to the outside through the main aeration nozzles 7, and the gas in the auxiliary aeration pipe 2 is output to the outside through the main aeration nozzles 7. The auxiliary aerator nozzle 8 outputs gas outwards. An air inlet pipe 3 is fixedly installed at one end of the main aerator pipe 1, so that gas will be filled into the main aerator pipe 1 when the air inlet pipe 3 is connected to the air inlet device. A weight block 6 is fixedly installed at the lower end of the electric push rod 5, so that the whole device tends to be stable and easy to use. At the same time, one end of the main aerator pipe 1 is fixedly connected to the telescopic end of the electric push rod 5 through the connecting block 4, so that the main aerator pipe 1 can work at different heights. The electric push rod 5 is waterproof, and part of the fixed end is located inside the weight block 6.

[0029] Working principle: When the operator needs to connect the auxiliary aeration pipe 2 to the main aeration pipe 1, the connecting block 16 on the second connecting plate 10 is aligned with the clamping plate 12 on the first connecting plate 9, and then the second connecting plate 10 is pushed. This causes the connecting block 16 to push the clamping plate 12 to rotate, so that the connecting block 16 is located between the two clamping plates 12. The spring 15 set between the clamping plate 12 and the base plate 11 keeps the clamping plate 12 in its original shape when no external force is applied, thus allowing the clamping plate 12 to firmly clamp the connecting block 16. This ensures a stable connection between the first connecting plate 9 and the second connecting plate 10. When the first connecting plate 9 and the second connecting plate 10 are slidably connected, the connecting pipe 17 and the connecting pipe 18 are slidably connected, allowing the gas in the main aeration pipe 1 to enter the secondary aeration pipe 2. When the secondary aeration pipe 2 needs to be disassembled and replaced, the operator forcefully slides the second connecting plate 10 away from the first connecting plate 9, thereby allowing the connecting block 16 to slide out of the clamping plate 12, and then the main aeration pipe 1 and the secondary aeration pipe 2 are separated.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
