Description

Technical Field

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

[0002] In the field of wastewater treatment, aeration tanks and aeration devices are core equipment for ensuring the activity of aerobic microorganisms, and their performance directly affects the wastewater purification efficiency. Currently, the mainstream aeration methods are divided into bottom-level blower aeration and surface mechanical aeration. The former supplies oxygen by delivering air through pipes to generate bubbles, while the latter relies on agitation to enhance water-air contact. However, both have significant limitations. Traditional equipment generally suffers from high energy consumption and high maintenance costs. Bottom-level fixed aeration pipes are prone to corrosion or blockage and failure, requiring the tank to be emptied during replacement, interrupting the treatment process and being time-consuming and labor-intensive. Simultaneously, uneven aeration frequently leads to dead zones, with insufficient dissolved oxygen in some areas, affecting the degradation of organic matter by microorganisms. Especially in the treatment of high-concentration industrial wastewater, these defects significantly reduce the purification effect and restrict the stable operation of the wastewater treatment system.

[0003] The patent publication number "CN219259716U" discloses "This utility model relates to the field of aeration devices, and discloses an aeration device for an aeration tank, which effectively solves the problem that settled sludge easily falls to the top of the aeration pipe, causing blockage and poor aeration effect. The device includes an aeration tank, with an installation frame installed at the top, an aeration assembly installed inside the aeration tank, and a cleaning assembly installed at the bottom of the installation frame. The aeration assembly includes a baffle installed on the bottom wall of the aeration tank, an aeration main pipe above the baffle, the outer wall of the aeration main pipe being in close contact with the baffle, and one end of the aeration main pipe being fixedly connected to the output shaft of a first motor. In this utility model, by turning on the first motor, the first motor rotates, causing the top of the aeration main pipe to continuously enter the contact position with the baffle. Because the bottom wall of the aeration main pipe is in close contact with the baffle, the sludge adhering to the aeration main pipe is scraped off under the action of the baffle, avoiding blockage and improving the aeration effect."

[0004] To address the aforementioned issues, existing aeration tank aeration devices have a relatively fixed aeration main pipe position, relying primarily on its own rotation in conjunction with baffles for cleaning. This lack of lateral movement to adjust the aeration position limits the aeration range, making it difficult to achieve uniform aeration across different areas of the tank. This can easily lead to aeration dead zones, affecting the overall aeration effect. Furthermore, this device only uses baffles to scrape sludge off the aeration main pipe to prevent clogging, lacking the ability to intercept and treat impurities around the aeration area. During aeration, suspended impurities may continuously adhere to the aeration components. Relying solely on scraping is insufficient to maintain the cleanliness of the aeration components in the long term, potentially impacting aeration efficiency over time. Utility Model Content

[0005] The purpose of this invention is to provide an aeration device for an aeration tank, which solves the problems of limited aeration range and dead zones caused by fixed aeration positions, avoids the long-term accumulation of impurities affecting the aeration components, and thus ensures long-term stable aeration efficiency.

[0006] To achieve the above objectives, this utility model provides an aeration device for an aeration tank, including an aeration tank.

[0007] It also includes that both sides of the top of the aeration tank are fixedly installed with sliding grooves, and a sliding rod is fixedly installed on the inner side of the right sliding groove;

[0008] A mounting bracket is slidably mounted on the outer side of the slide rod. A rotating assembly is provided on the top side of the mounting bracket. The rotating assembly includes a U-shaped plate, which is fixedly mounted on the top side of the mounting bracket. A secondary motor is fixedly mounted on the top side of the U-shaped plate. A secondary gear and a main gear are rotatably mounted on the top side of the mounting bracket. The motor shaft of the secondary motor passes through the U-shaped plate and is fixedly connected to the secondary gear. The secondary gear and the main gear mesh with each other.

[0009] An aeration pipe is rotatably installed on the inner side of the slide groove, and the aeration pipe is screwed through the interior of the slide block. A main motor is fixedly installed on the outer side of the aeration tank, and the output shaft of the main motor passes through the slide groove and is fixedly connected to the aeration pipe.

[0010] The mounting bracket has a pad fixedly installed on top, an aeration pump fixedly installed on top of the pad, an aeration pipe fixedly installed on the side of the aeration pump, and the other end of the aeration pipe is rotatably connected to the main gear.

[0011] The mounting frame has an air intake pipe rotatably mounted at its bottom. The air intake pipe movably passes through the mounting frame and is fixedly connected to the main gear. The air intake pipe is connected to the aeration pipe. A worm gear fan blade is fixedly mounted on the outside of the air intake pipe.

[0012] The aeration pipe is fixedly installed at the bottom of the aeration pipe, and the exhaust pipe is fixedly installed at the bottom of the exhaust pipe.

[0013] The mounting frame has a shock-absorbing component fixedly installed on its inner side, and a sieve plate is fixedly installed at the bottom of the shock-absorbing component. The sieve plate has sieve holes inside.

[0014] This utility model discloses an aeration device for an aeration tank. The aeration device has sliding grooves fixedly installed on both sides of the top of the aeration tank, and a sliding rod installed on the inner side of the right sliding groove, allowing the mounting frame to slide on the sliding rod, providing a basis for adjusting the aeration position. At the same time, in the rotating assembly on the top side of the mounting frame, the secondary motor drives the secondary gear to rotate, and the secondary gear meshes with the main gear to drive the main gear to rotate, so that the device has rotational power. This structural design allows the mounting frame to move along the sliding rod to change the lateral aeration position, and also enables the rotation of related components via the rotating assembly. This makes aeration operation more flexible, provides more comprehensive coverage of the aeration tank, avoids aeration dead zones, improves aeration uniformity, and ensures consistent wastewater treatment effects throughout the aeration tank. The screen plate on the bottom of the shock-absorbing assembly, with its perforated screen, effectively intercepts suspended impurities around the aeration area, preventing them from being drawn into the worm gear blades or adhering to the aeration components. This avoids interference and blockage of the aeration components. Combined with the device's flexible movement and rotation capabilities, this further enhances the stability and long-term efficiency of the aeration device, making the entire aeration process smoother.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figures 1-5 .

[0024] An aeration device for an aeration tank includes an aeration tank 1;

[0025] It also includes a slide chute 2 fixedly installed on both sides of the top of the aeration tank 1, and a slide rod 17 fixedly installed on the inner side of the right slide chute 2;

[0026] A mounting bracket 3 is slidably mounted on the outer side of the slide rod 17. A rotating assembly 6 is provided on the top side of the mounting bracket 3. The rotating assembly 6 includes a U-shaped plate 61. The U-shaped plate 61 is fixedly mounted on the top side of the mounting bracket 3. A secondary motor 62 is fixedly mounted on the top side of the U-shaped plate 61. A secondary gear 64 and a main gear 63 are rotatably mounted on the top side of the mounting bracket 3. The motor shaft of the secondary motor 62 passes through the U-shaped plate 61 and is fixedly connected to the secondary gear 64. The secondary gear 64 and the main gear 63 mesh with each other.

[0027] First, the aeration device for the aeration tank has sliding grooves 2 fixedly installed on both sides of the top of the aeration tank 1. A sliding rod 17 is fixedly installed on the inner side of the right sliding groove 2, and a mounting frame 3 is slidably installed on the outer side of the sliding rod 17. This structural design allows the mounting frame 3 to slide stably based on the sliding rod 17, providing a flexible moving basis for adjusting the position of the aeration operation, facilitating precise aeration for different areas within the aeration tank 1. A rotating assembly 6 is provided on the top side of the mounting frame 3. The rotating assembly 6 includes a U-shaped plate 61, which is fixedly installed on the top side of the mounting frame 3. A secondary motor 62 is fixedly installed on the top side of the U-shaped plate 61. A secondary gear 64 and a main gear 63 are rotatably installed on the top side of the mounting frame 3. The motor shaft of the secondary motor 62 passes through the U-shaped plate 61 and is fixedly connected to the secondary gear 64. The secondary gear 64 and the main gear 63 mesh. After the secondary motor 62 is started, its motor shaft drives the secondary gear 64 to rotate, which in turn drives the main gear 63 to rotate synchronously through the gear meshing relationship, providing the core driving force for the power transmission of the device and the operation of subsequent components.

[0028] Furthermore, an aeration pipe 9 is rotatably installed on the inner side of the slide 2. The aeration pipe 9 is screwed through the interior of the slider 4. A main motor 5 is fixedly installed on the outer side of the aeration tank 1. The output shaft of the main motor 5 passes through the slide 2 and is fixedly connected to the aeration pipe 9. When the main motor 5 is working, the output shaft directly drives the aeration pipe 9 to rotate. Since the aeration pipe 9 is screwed to the slider 4, the rotation of the aeration pipe 9 is converted into the linear movement of the slider 4 along the slide 2, which in turn drives the mounting frame 3 to move horizontally, thereby expanding the aeration range laterally. At the same time, the design precision of this screwed connection is high, which can ensure the smoothness and accuracy of the movement of the slider 4, making the translation process of the mounting frame 3 more reliable and avoiding the impact of unstable movement on the aeration effect.

[0029] Furthermore, a pad 7 is fixedly installed on the top of the mounting bracket 3, and an aeration pump 8 is fixedly installed on the top of the pad 7. An aeration pipe 9 is fixedly installed on the side of the aeration pump 8, and the other end of the aeration pipe 9 is rotatably connected to the main gear 63. The pad 7 is made of high-strength material, which can effectively distribute the weight of the aeration pump 8 and provide it with stable support. Even if the aeration pump 8 operates at high intensity for a long time and generates large vibrations, it can maintain its own stability and that of the aeration pump 8. The high-pressure gas generated by the aeration pump 8 is delivered to the main gear 63 through the aeration pipe 9. The rotatable connection design has been precisely calculated and adjusted to ensure that the gas delivery channel remains unobstructed when the main gear 63 rotates at different speeds, without gas leakage or delivery interruption, thus ensuring a continuous and stable gas supply.

[0030] Furthermore, an air inlet pipe 10 is rotatably mounted on the bottom of the mounting frame 3. The air inlet pipe 10 movably passes through the mounting frame 3 and is fixedly connected to the main gear 63. The air inlet pipe 10 is connected to the aeration pipe 9, and a worm gear fan blade 11 is fixedly mounted on the outer side of the air inlet pipe 10. When the main gear 63 rotates, it synchronously drives the air inlet pipe 10 to rotate. The worm gear fan blade 11 rotates at high speed with the air inlet pipe 10. The special angle design of its blades can maximize the acceleration of gas flow, improve the gas transmission efficiency in the pipeline, and reduce energy loss during gas transportation. At the same time, the high-speed rotating worm gear fan blade 11 forms a uniform and powerful stirring effect on the liquid in the aeration tank, breaking the static state of the liquid and allowing the gas to diffuse more evenly into the liquid, greatly improving the gas-liquid mixing efficiency. The connection between the air inlet pipe 10 and the aeration pipe 9 is sealed to ensure that the gas does not leak during transportation and to guarantee a continuous gas supply.

[0031] Furthermore, an exhaust pipe 12 is fixedly installed at the bottom of the aeration pipe 9, and an exhaust hole 13 is fixedly installed at the bottom of the exhaust pipe 12. A shock-absorbing component 14 is fixedly installed on the inner side of the mounting frame 3, and a screen plate 15 is fixedly installed at the bottom of the shock-absorbing component 14. The screen plate 15 is located on the outer side of the worm gear fan blade 11 and has screen holes 16 all inside. Gas is released from the exhaust hole 13 through the exhaust pipe 12. The distribution of the exhaust holes 13 is relatively uniform, which allows the gas to enter the aeration tank in a more dispersed form, increasing the contact area between the gas and the liquid and completing the efficient aeration process. The screen plate 15 on the outer side of the worm gear fan blade 11 is made of corrosion-resistant material, and its mesh size is reasonably designed to effectively intercept suspended impurities in the aeration tank, preventing these impurities from being drawn into the worm gear fan blade 11 and affecting its operation. At the same time, the design of the screen holes 16 ensures that the liquid can flow normally and will not obstruct the circulation of the liquid in the tank. The shock absorption assembly 14 has an elastic element inside, which can effectively absorb and buffer the vibration generated during the operation of the device, reduce the impact of vibration on the mounting frame 3 and other component connections, improve the overall stability and service life of the device, and reduce the probability of component wear and failure caused by vibration.

[0032] Overall workflow:

[0033] After the device is started, the main motor 5 begins to work, and its output shaft drives the aeration pipe 9 to rotate. Since the aeration pipe 9 is screwed through the slider 4, the slider 4 moves laterally along the slide groove 2 under the action of the rotation of the aeration pipe 9, thereby driving the mounting frame 3 to move synchronously, thus expanding the lateral coverage of the aeration device. At the same time, the secondary motor 62 starts, and its motor shaft drives the secondary gear 64 to rotate. Since the secondary gear 64 meshes with the main gear 63, the main gear 63 rotates accordingly. On the one hand, the air intake pipe 10, which is fixedly connected to the main gear 63, rotates synchronously, causing the worm gear fan blade 11 on the outside of the air intake pipe 10 to rotate. During the rotation of the worm gear fan blade 11, it not only accelerates the air in the air intake pipe 10, but also... The flow also stirs the liquid in the aeration tank 1, improving the gas-liquid mixing effect. On the other hand, the gas generated by the aeration pump 8 is transported to the main gear 63 through the aeration pipe 9, and then enters the exhaust pipe 12 through the air inlet pipe 10 connected to the main gear 63. Finally, it is released into the aeration tank 1 from the exhaust hole 13 at the bottom of the exhaust pipe 12, completing the aeration operation. During this process, the screen plate 15 located outside the worm gear fan blade 11 intercepts suspended impurities in the aeration tank 1 through the screen holes 16, preventing impurities from affecting the normal operation of the worm gear fan blade 11. The shock absorption component 14 inside the mounting frame 3 effectively buffers the vibration generated during the operation of the device, ensuring that the entire device works stably and efficiently.
