Description

Technical Field

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

[0002] Wastewater treatment is the process of treating wastewater containing organic matter, chemical substances, microorganisms, etc., through a series of physical, chemical, and biological methods to make it meet environmental standards and be reusable.

[0003] Existing aeration devices cannot change the position of the nozzles during use, resulting in poor mixing effect. In addition, most aeration devices are fixed in one place, which can easily cause sediment to settle in the vicinity during aeration. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to provide an aeration device for sewage treatment, which is designed to rotate together with the rotating ring by means of a rotating rod, so that the aeration is sprayed out while rotating and stirring, making it difficult for the sediment to settle and accumulate.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] The device includes a base, on which a stirring mechanism is disposed. The stirring mechanism includes a rotating ring, a rotating rod, and a support rod. The rotating ring is rotatably disposed on the upper surface of the base. The support rod is integrally disposed on the upper surface of the rotating ring. The rotating rod is rotatably disposed in the middle of the support rod. An adjustment mechanism is disposed inside the rotating rod. The adjustment mechanism includes an extension block, an adjustment rod, and an adjustment tube. The extension block is integrally disposed in the middle of the support rod. The surface of the extension block contacts the adjustment rod. The adjustment rod is slidably disposed inside the rotating rod. A holding spring is disposed between the adjustment rod and the rotating rod. A positioning rod is rotatably disposed on the upper surface of the base.

[0007] The technical solution of this utility model has achieved the following beneficial technical effects:

[0008] The rotating rod, which rotates along with the rotating ring, can agitate the material while it is being sprayed with aeration, preventing sediment from settling and accumulating. It also allows for changes in the aeration angle. The rotating rod, which rotates on the support rod, rotates towards the bottom while spraying aeration, causing sediment at the bottom to shift position due to the aeration's vibrations. Furthermore, the rotation of the rod changes the aeration spray angle, ensuring that sediment at different locations makes full contact with the aeration. Attached Figure Description

[0014] This implementation example is attached to the instruction manual. Figure 1-4 As shown, the instruction manual is attached. Figure 1 A structural diagram is attached to the instruction manual. Figure 2 Appendix Figure 1 The structure was cut in half based on the existing structure. (Instruction manual attached) Figure 3 The top of rotating rod 3 was cut off. Due to the length of rotating rod 3, a wavy line was used to represent a portion of the design. (See attached instruction manual.) Figure 4 The rotating rod 3 is cut in half. The base 1 is bolted to the bottom of the aeration tank. A rotating ring 2 is rotatably mounted on the top of the base 1. The two rotate in a sealed manner and have an anti-detachment structure. The rotating ring 2 is driven by rotating teeth. A servo motor (all motors used in this solution have a self-locking function) is installed below the rotating teeth. Therefore, the motor can make the rotating teeth rotate. The motor is installed inside the base 1. One side of the rotating teeth meshes with the rotating ring 2, so the rotating ring 2 can rotate. The rotation of the rotating ring 2 can drive the rotating rod 3 above to rotate together, which can stir the liquid and make the liquid and aeration fully mixed.

[0015] Based on the rotation of the rotating ring 2, this design includes a positioning rod 9 on the base 1. A servo motor is located below the positioning rod 9, controlling its rotation and maintaining its position. When the positioning rod 9 is stationary, the rotation of the rotating ring 2 drives the rotating rod 3 to rotate laterally. A torsion spring 22 is located on the edge of the rotating rod 3, ensuring its horizontal position. To allow the rotating rod 3 to rotate on the support rod 4, a protruding positioning block 11 is provided above the positioning rod 9. The rotating rod 3 approaches the positioning block 11... Position 1 is an extended circular rod. As the rotating rod 3 moves in a circular motion along with the support rod 4, its edge contacts the positioning block 11. Under the action of the positioning block 11, the rotating rod 3 is lifted, causing it to rotate on the support rod 4. The rotating rod 3 will rotate downwards while moving in a circular motion, achieving a vertical rotation and stirring effect. The rotating spring 22 maintains its position again when the rotating rod 3 is separated from the positioning block 11. In order to make the downward rotation position of the rotating rod 3 variable, a servo motor is set below the positioning rod 9, which can adjust the position of the positioning rod 9 at timed intervals.

[0016] The base 1 is provided with an annular channel 12. The top of the annular channel 12 is annular and extends outwards to form a tube. This tube can be connected to an aeration device to supply aeration to the annular channel 12. Above the annular channel 12 is an internal channel 13, which is located below the rotating ring 2. Since the rotating ring 2 is rotating and the rotating ring 2 and the base 1 are sealed and rotated, the aeration from the annular channel 12 reaches the internal channel 13. The internal channel 13 extends upwards and reaches the interior of the rotating rod 3 through the support rod 4. The interior of the support rod 4 is hollow, which allows the aeration to reach the rotating rod 3. The support rod 4 and the rotating rod 3 are also sealed and rotated.

[0017] As per the instruction manual Figure 2 As shown, rotating the left-hand rotating rod 3 counterclockwise will cause the adjusting rod 6 to move to the right. This is because the right side of the adjusting rod 6 has a cylindrical part that contacts the extension block 5, which is arc-shaped, as shown in the instruction manual. Figure 3As shown, the center of the arc coincides with the rotation center of the rotating rod 3. There is an inner chamfer above the extension block 5. The adjusting rod 6 rotates downwards with the rotating rod 3, causing it to move to the right under the guidance of the inner chamfer. After the rotating rod 3 rotates counterclockwise to the bottom and reaches below the extension block 5, it returns (because the rotating spring 22 will reset it, while the maintaining spring 8 ensures that the right-side circular block of the adjusting rod 6 reaches the center, so that the circular block is within the range of the upper and lower chamfers, and the rotation angle of the rotating rod 3 covers the range of the extension block 5). The extension block 5 is integrally mounted on the support rod 4, so relative to the rotating rod... (The rotating rod 3 remains stationary during rotation). The extension block 5 has an outer chamfer below it. Under the action of the extension block 5, the adjusting rod 6 will have to move laterally to the left. In summary, when the rotating rod 3 rotates downwards, the adjusting rod 6 will move closer to the rotation center of the rotating rod 3. When the rotating rod 3 rotates upwards, the adjusting rod 6 will move away from the rotation center of the rotating rod 3. The left side of the adjusting rod 6 overlaps with the adjusting groove 10, which is an arc-shaped spiral. The adjusting rod 6 is rotatably set inside the rotating rod 3. This will cause the adjusting rod 6 to control the rotation of the adjusting tube 7, and the two rotation directions will be different.

[0018] As per the instruction manual Figure 4 As shown in the previous paragraph, the direction of rotation of the rotating rod 3 will cause the regulating pipe 7 to have two different directions. At this time, the regulating pipe 7 of this scheme rotates counterclockwise by a certain angle, which will cause the top port 18 and the first port 19 to connect. In this way, the aeration will reach the top port 18 through the first port 19 and be discharged along the top port 18. If the regulating pipe 7 rotates clockwise by a certain angle, it will cause the bottom port 20 to connect with the second block. In this way, the aeration will be discharged along the bottom port 20 through the second port 21. That is, rotating the rotating rod 3 downward causes the aeration to be discharged along the bottom port 20 (there are two bottom ports 20), and rotating the rotating rod 3 upward causes the aeration to be discharged along the top port 18. In this way, the aeration can blow the sediment below the aeration tank with the rotation of the rotating rod 3, making the sediment easy to float. The aeration spray, with a certain kinetic energy, can make the sediment move a certain distance. The rotating ring 2 of this scheme rotates slowly, which facilitates full contact with the aeration for reaction.

[0019] As per the instruction manual Figure 2 As shown, a switching rod 14 slides in the middle of the support rod 4. The switching rod 14 is hollow and can also discharge aeration. A switching spring is provided between the switching rod 14 and the support rod 4 to keep the switching rod 14 in the position as shown in the instruction manual. Figure 2As shown, the switching spring is in the extended state at this time, and the top of the switching rod 14 is in contact with the bottom of the rotating rod 3. If the rotating rod 3 moves away from the switching rod 14, the switching rod 14 will extend upward under the action of the switching spring (the rotating rod 3 moving away from the switching rod 14 corresponds to the rotating rod 3 contacting the positioning block 11). The upward extension of the switching rod 14 will cause the bottom block 16 to block the bottom opening 15, so that the aeration will not be sprayed out along the side opening 17 of the switching rod 14. Conversely, if the rotating rod 3 does not contact the positioning block 11, the side opening 17 of the switching rod 14 will spray out aeration, which can make the sediment move towards the other rotating rod 3 under the action of aeration, so as to facilitate mixing.

A retaining spring 8 is provided between the adjustment rod 6 and the rotating rod 3. A positioning rod 9 is rotatably mounted on the upper surface of the base 1.
