Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a precise aeration device for sewage treatment. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. When using an aeration device to treat sewage, oxygen-containing air is input into the bottom of the water, floats up in the form of bubbles, and dissolves the oxygen in the air into the water, providing oxygen for aerobic purification.

[0003] For example, publication number CN215403334U discloses a sewage treatment aeration tank, including a frame, an inner bottom wall of the frame is fixedly connected to a motor box, an upper surface of the motor box is fixedly inlaid with a sealed bearing, the inner bottom wall of the frame is fixedly connected to a first motor, an output end of the first motor is fixedly connected to a rotating rod via a reducer, the top end of the rotating rod passes through the sealed bearing and extends to the top of the motor box, and the outer surface of the rotating rod is fixedly connected to the inner wall of the sealed bearing.

[0004] However, the output value of the existing aeration device is fixed during use and cannot be adjusted according to the changes in oxygen and soil concentration in the sewage, which often leads to energy waste or poor sewage treatment effect. Secondly, the problem of uneven aeration also occurs from time to time during long-term use, which seriously affects the normal treatment effect of sewage. Utility Model Content

[0005] The utility model aims to solve the problem of adjusting according to the changes of oxygen and soil concentration in sewage in the prior art, and proposes a precise aeration device for sewage treatment.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a precise aeration device for sewage treatment, comprising a blower and an aeration pipe, an adjustment mechanism is installed on one side of the blower, one end of the adjustment mechanism is connected to the aeration pipe, a support frame is installed on one side of the aeration pipe, a threaded pipe is rotatably connected to the inner side of the support frame, a moving frame is slidably connected to the surface of the threaded pipe, a moving block is fixedly connected to one side of the moving frame, a sliding rod is slidably connected to the inner side of the moving block, and the side wall of the threaded pipe is fixedly connected to the aeration pipe;

[0007] The blower comprises a frame and a mounting frame, wherein the mounting frame is fixedly connected to the inner wall of the frame, a first baffle is fixedly connected to the inner wall of the frame, and a second baffle and a third baffle are arranged on one side of the mounting frame.

[0008] Preferably, the frame side wall is provided with an arc groove, and the second baffle plate and the third baffle plate side walls are both equipped with movable components.

[0009] Preferably, a first rotating ring and a second rotating ring are sleeved in the middle of the mounting frame, and two stoppers are fixedly connected to the middle of the mounting frame.

[0010] Preferably, the second baffle is fixedly connected to the outer wall of the second rotating ring, and the third baffle is fixedly connected to the outer wall of the first rotating ring.

[0011] Preferably, the moving assembly comprises a sliding block, and a locking rod is provided on one side of the sliding block.

[0012] Preferably, one end of the locking rod passes through the sliding block, and one end of the locking rod abuts against an outer wall of the frame.

[0013] Preferably, a limit plate is provided inside the sliding block, the limit plate is fixedly connected to the outer wall of the locking rod, and a spring is sleeved on one end of the locking rod.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. In the utility model, the interaction between the threaded pipe and the mobile frame realizes the flexible adjustment of the position of the aeration pipe, enhances the accuracy and uniformity of aeration, and prevents the aeration problem of aeration in a fixed position for a long time. At the same time, by using the rotatable baffle and the blower power adjustment, the gas emission can be accurately controlled according to the sewage situation, effectively avoiding energy waste.

[0016] 2. In the utility model, when the first rotating ring and the second rotating ring rotate respectively, their cooperation with the block can limit the rotation angle of the third baffle and the second baffle, ensuring that they work within a preset range, which not only improves the flexibility of the system, but also enhances its stability. The baffle can be easily adjusted by stretching and moving the locking rod, and after the adjustment is completed, it can be fixed in the desired position to prevent it from rotating at will. This design ensures that the angle of the area where the frame discharges air can be freely adjusted between 90 degrees and 270 degrees, thereby meeting the needs of different scenarios.

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Embodiment 1

[0024] like Figure 1-3 As shown, the utility model provides a precise aeration device for sewage treatment, including a blower 3 and an aeration pipe 1, an adjustment mechanism 2 is installed on one side of the blower 3, one end of the adjustment mechanism 2 is connected to the aeration pipe 1, a support frame 4 is installed on one side of the aeration pipe 1, a threaded pipe 6 is rotatably connected to the inner side of the support frame 4, a moving frame 7 is slidably connected to the surface of the threaded pipe 6, a moving block 5 is fixedly connected to one side of the moving frame 7, a sliding rod 8 is slidably connected to the inner side of the moving block 5, and a side wall of the threaded pipe 6 is fixedly connected to the aeration pipe 1;

[0025] The blower 3 includes a frame 21 and a mounting frame 22 . The mounting frame 22 is fixedly connected to the inner wall of the frame 21 . A first baffle 24 is fixedly connected to the inner wall of the frame 21 . A second baffle 25 and a third baffle 26 are arranged on one side of the mounting frame 22 .

[0026] The specific configuration and function of this embodiment are described in detail below. During the aeration process, by rotating the threaded tube 6, a force can be applied to the movable frame 7. In this way, when the threaded tube 6 rotates, it can control the movement of the movable frame 7. As the movable frame 7 moves on the surface of the threaded tube 6, it also drives the movable block 5 to slide on the surface of the slide rod 8, thereby adjusting the position of the aeration tube 1. This design not only improves the accuracy of aeration, but also ensures the uniformity of aeration, avoiding aeration at the same position for a long time.

[0027] In addition, by enabling the second baffle 25 and the third baffle 26 to rotate, the amount of gas discharged from the frame 21 can be controlled. Combined with the power of the blower 3, it can be adjusted according to the oxygen and soil concentration in the sewage, thereby avoiding energy waste.

[0028] During use, the threaded pipe 6 can rotate and connect to an external power device to achieve full automatic operation, which further improves the aeration effect. The two threads on the surface of the threaded pipe 6 enable the moving frame 7 to start moving back when it moves to the end of one end of the threaded pipe 6. Embodiment 2

[0029] like Figure 3 and Figure 4 As shown, an arc groove 211 is provided on the side wall of the frame 21, and a moving assembly 23 is installed on the side walls of the second baffle plate 25 and the third baffle plate 26. A first rotating ring 222 and a second rotating ring 223 are sleeved in the middle of the mounting frame 22, and two baffles 221 are fixedly connected in the middle of the mounting frame 22. The second baffle plate 25 is fixedly connected to the outer wall of the second rotating ring 223, and the third baffle plate 26 is fixedly connected to the outer wall of the first rotating ring 222. The moving assembly 23 includes a sliding block 231, and a locking rod 232 is provided on one side of the sliding block 231. One end of the locking rod 232 passes through the sliding block 231, and one end of the locking rod 232 abuts against the outer wall of the frame 21. A limiting plate 234 is provided inside the sliding block 231, and the limiting plate 234 is fixedly connected to the outer wall of the locking rod 232, and a spring 233 is sleeved on one end of the locking rod 232.

[0030] The effect achieved by the entire embodiment is that when the first rotating ring 222 rotates in the middle of the mounting frame 22, due to the length of the internal groove of the first rotating ring 222 and the cooperation of the stopper 221, it can effectively limit the rotation angle of the third baffle 26. Similarly, the cooperation of the second rotating ring 223 and the stopper 221 can also limit the rotation angle of the second baffle 25. Therefore, the third baffle 26 can rotate 180 degrees, and the second baffle 25 can rotate 90 degrees. When they rotate to the extreme position, they will completely overlap with the area defined by the first baffle 24, so that the angle of the area where the frame 21 can discharge air can reach a maximum of 270 degrees. This means that the adjustment range of the area where the frame 21 discharges air is from 90 degrees to 270 degrees.

[0031] When adjusting the third baffle 26 and the second baffle 25, the adjustment can be achieved by sliding the moving assembly 23 inside the stopper 221. During the adjustment process, the locking rod 232 needs to be stretched so that it is no longer in contact with the frame 21. After the adjustment is completed, the locking rod 232 is released, and the limit plate 234 will push the locking rod 232 to move together under the elastic force of the spring 233 until one end of the locking rod 232 is in close contact with the outer wall of the frame 21. This design can effectively prevent the second baffle 25 and the third baffle 26 from rotating at will, ensuring the stable operation of the system.

[0032] The use method and working principle of the device: When aeration is performed, by rotating the threaded tube 6, a force can be applied to the mobile frame 7, thereby controlling the mobile frame 7 to move along the surface of the threaded tube 6. As the mobile frame 7 moves, the moving block 5 will also slide on the surface of the slide bar 8, thereby adjusting the position of the aeration tube 1. This design not only improves the accuracy of aeration, but also ensures the uniformity of aeration, avoiding aeration at the same position for a long time.

[0033] In addition, when the first rotating ring 222 rotates in the middle of the mounting frame 22, the cooperation between its internal groove and the stopper 221 limits the rotation angle of the third baffle 26. Similarly, the cooperation between the second rotating ring 223 and the stopper 221 also limits the rotation angle of the second baffle 25. Therefore, the third baffle 26 can rotate 180 degrees, while the second baffle 25 can rotate 90 degrees. When they rotate to the extreme position, they completely overlap with the area defined by the first baffle 24, so that the angle of the area where the frame 21 can discharge air can reach a maximum of 270 degrees. This means that the adjustment range of the area where the frame 21 discharges air is from 90 degrees to 270 degrees.

[0034] When adjusting the third baffle 26 and the second baffle 25, it can be achieved by sliding the moving component 23 inside the block 221. During the adjustment process, stretch the locking rod 232 so that it is no longer in contact with the frame 21. After the adjustment is completed, release the locking rod 232. At this time, the limit plate 234 will push the locking rod 232 to move together under the elastic force of the spring 233 until one end of the locking rod 232 is in close contact with the outer wall of the frame 21. This design can effectively prevent the second baffle 25 and the third baffle 26 from rotating at will, ensuring the stable operation of the system. The amount of gas discharged from the frame 21 can be controlled by rotating the second baffle 25 and the third baffle 26. Combined with the power of the blower 3, it can be adjusted according to the oxygen and soil concentrations in the sewage to avoid energy waste.

[0035] During use, the threaded pipe 6 can be connected to an external power device for rotation to achieve full automatic operation, which further improves the aeration effect. The two threads on the surface of the threaded pipe 6 enable the moving frame 7 to start moving back when it moves to the end of one end of the threaded pipe 6.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
