Description

Technical Field

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

[0002] An aeration disc is a commonly used microporous aeration device in wastewater treatment. It cuts air into tiny bubbles through tiny pores on a membrane to increase the dissolved oxygen content in the water, providing the necessary oxygen conditions for the metabolic activities of aerobic microorganisms. It is the core oxygen supply component in the activated sludge process.

[0003] Current aeration discs mainly consist of a base, an elastic diaphragm, an air inlet pipe, and a pressure cap. During installation, holes need to be drilled in the PVC pipes laid at the bottom of the pool. The air inlet pipe of the aeration disc is inserted into the holes and secured with adhesive or pipe clamps. After installation, the aeration disc should be kept horizontal, with the diaphragm surface facing vertically upwards to ensure even stress on the diaphragm and symmetrical bubble distribution, thereby guaranteeing uniform aeration and efficient oxygen transfer.

[0004] However, during the on-site installation of aeration discs, manufacturing or installation errors in the PVC pipes can cause inherent deflection. Combined with potential angular deviations during drilling, the centerline of the mounting hole may not be perfectly perpendicular to the horizontal plane. When the air inlet pipe is inserted into this skewed hole, the aeration disc also tilts. This tilt leads to uneven bubble distribution and affects aeration efficiency. Existing connection methods are mostly rigid, fixed structures that cannot adjust the tilt angle after installation, making it difficult to meet the requirements of standardized installation. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an aeration mechanism for wastewater treatment. By installing a telescopic hose at the lower end of the air inlet pipe of the aeration disc, a flexible and deformable connection is formed between the aeration disc and the air supply pipe. When the mounting hole is not perpendicular due to drilling deviation or pipe torsion, the angle deviation of the mounting hole can be compensated by rotating the aeration disc and utilizing the bending and torsion characteristics of the telescopic hose, so that the aeration disc can be adjusted to a horizontal state independently of the pipe deflection.

[0006] The technical solution adopted to solve the above-mentioned technical problems is: an aeration mechanism for sewage treatment, including a pipe, an aeration disc, an air inlet pipe, a mounting hole, a pipe clamp, a connecting pipe, and a telescopic hose. The air inlet pipe is connected to the bottom of the aeration disc. The mounting hole is opened on the pipe. The pipe clamp is detachably connected to the mounting hole. The connecting pipe is integrally set with the pipe clamp and is inserted into the mounting hole. The telescopic hose is coaxially connected to the lower end of the air inlet pipe and is detachably connected to the connecting pipe.

[0007] Furthermore, it also includes a connector and a rotating sleeve. The connector is coaxially fixed to the lower end of the telescopic hose. The connector is inserted into the connecting pipe and sealed to the connecting pipe. The rotating sleeve is rotatably connected to the outside of the connector and screwed to the connecting pipe.

[0008] Furthermore, it also includes an arc-shaped rod, an arc-shaped sleeve, a support rod, a threaded sleeve, a stud, and a locking screw. Arc-shaped rods are fixedly connected to both sides of the air intake pipe. The arc-shaped rods are coaxially arranged with the pipe. The arc-shaped sleeves are slidably fitted on the outside of the arc-shaped rods. The support rods are fixedly connected to the inside of the arc-shaped sleeves. The threaded sleeves are movably connected to the lower end of the support rods. Studs are integrally connected to both sides above the pipe clamp. The threaded sleeves and studs are screwed one-to-one. The locking screws pass through the arc-shaped sleeves and are threadedly connected to them. The locking screws are used to abut against the arc-shaped rods.

[0009] Furthermore, it also includes a limiting ring and a sealing ring. The limiting ring is coaxially connected to the inner side of the connecting pipe and is used to limit the insertion pipe. The sealing ring is connected between the limiting ring and the insertion pipe.

[0010] Furthermore, it also includes liquid level beads, which are connected to one side of the aeration disc.

[0011] Furthermore, it also includes bolts, sealing rings, slots, and sealing strips. The pipe clamp includes an upper clamp and a lower clamp, which are connected by bolts. The connecting pipe is integrally connected to the upper clamp. The stud is connected to the upper clamp. The sealing ring is sleeved on the lower side of the connecting pipe. Slots are provided on both sides of the upper clamp, and the sealing strip is connected to the slots.

[0012] The beneficial effects of this utility model are as follows: By setting a telescopic hose at the lower end of the air inlet pipe of the aeration disc, a flexible and deformable connection is formed between the aeration disc and the air supply pipe. When the mounting hole is not perpendicular due to drilling deviation or pipe torsion, the angle deviation of the mounting hole can be compensated by rotating the aeration disc and utilizing the bending and torsion characteristics of the telescopic hose. This allows the aeration disc to be adjusted to a horizontal state independently of the pipe deflection, effectively solving the problem that the traditional rigid connection method cannot adjust the angle, and ensuring the installation accuracy and aeration uniformity of the aeration disc.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] like Figures 1-6 As shown in the figure, the aeration mechanism for sewage treatment provided in this embodiment includes a pipe 1, an aeration disc 2, an air inlet pipe 3, a mounting hole 4, a pipe clamp 5, a connecting pipe 6, and a telescopic hose 7. The air inlet pipe 3 is connected to the bottom of the aeration disc 2. The mounting hole 4 is opened on the pipe 1. The pipe clamp 5 is detachably connected to the mounting hole 4. The connecting pipe 6 is integrally set with the pipe clamp 5 and is inserted into the mounting hole 4. The telescopic hose 7 is coaxially connected to the lower end of the air inlet pipe 3 and is detachably connected to the connecting pipe 6.

[0022] In the above embodiments, by setting a flexible hose 7 at the lower end of the air inlet pipe 3 of the aeration disc 2, a flexible and deformable connection is formed between the aeration disc 2 and the air supply pipe 1. When the mounting hole 4 is not perpendicular due to drilling deviation or the pipe 1 itself twisting, the angle deviation of the mounting hole 4 can be compensated by rotating the aeration disc 2 and utilizing the bending and twisting characteristics of the flexible hose 7. This allows the aeration disc 2 to be adjusted to a horizontal state independently of the pipe 1's deflection, effectively solving the problem that the traditional rigid connection method cannot adjust the angle, and ensuring the installation accuracy and aeration uniformity of the aeration disc 2.

[0023] Specifically, it also includes a connector 8 and a rotating sleeve 9. The connector 8 is coaxially fixed to the lower end of the telescopic hose 7. The connector 8 is inserted into the connecting pipe 6 and the connector 8 and the connecting pipe 6 are sealed together. The rotating sleeve 9 is rotatably connected to the outside of the connector 8 and is screwed to the connecting pipe 6.

[0024] In the above embodiments, by setting the insertion pipe 8 and the rotating sleeve 9, a quick and sealed connection between the aeration disc 2 and the connecting pipe 6 is achieved. The insertion pipe 8 is inserted into the connecting pipe 6 and locked by the rotating sleeve 9, which not only ensures the continuity of the air passage, but also facilitates the disassembly and maintenance of the aeration disc 2 in the later stage without damaging the connection of the pipe 1.

[0025] Specifically, it also includes an arc-shaped rod 10, an arc-shaped sleeve 11, a support rod 12, a screw sleeve 13, a stud 14, and a locking screw 15. Arc-shaped rods 10 are fixedly connected to both sides of the air intake pipe 3. The arc-shaped rods 10 are coaxially arranged with the pipe 1. The arc-shaped sleeve 11 is slidably sleeved on the outside of the arc-shaped rod 10. The support rod 12 is fixedly connected to the inside of the arc-shaped sleeve 11. The screw sleeve 13 is movably connected to the lower end of the support rod 12 (it can rotate or slide relative to it). The upper sides of the pipe clamp 5 are integrally connected with studs 14. The screw sleeve 13 and the stud 14 are screwed one-to-one. The locking screw 15 passes through the arc-shaped sleeve 11 and the two are threadedly connected. The locking screw 15 is used to tighten the arc-shaped rod 10.

[0026] In the above embodiments, by setting the sliding fit structure of the arc rod 10 and the arc sleeve 11, a precise guide trajectory is provided for the rotational adjustment of the aeration disc 2 along the axis of the pipe 1. At the same time, combined with the detachable connection of the screw sleeve 13 and the stud 14 and the locking function of the locking screw 15, the aeration disc 2 can be quickly positioned and rigidly locked after being adjusted to a horizontal position, effectively preventing loosening caused by water flow impact or operating vibration, and ensuring the stability of long-term operation.

[0027] Specifically, it also includes a limiting ring 16 and a sealing ring 17. The limiting ring 16 is coaxially connected to the inside of the connecting pipe 6 and is used to limit the insertion pipe 8. The sealing ring 17 is connected between the limiting ring 16 and the insertion pipe 8.

[0028] In the above embodiments, by providing a limiting ring 16 and a sealing ring 17 on the inner side of the connecting pipe 6, the limiting ring 16 can provide accurate axial positioning when the insert pipe 8 is inserted, preventing the insert pipe 8 from being inserted too deeply or too shallowly, ensuring reliable connection. The sealing ring 17 is deformed under pressure between the limiting ring 16 and the insert pipe 8 to form an end face seal, effectively preventing compressed air leakage at the connection and ensuring air supply efficiency.

[0029] Specifically, it also includes liquid level beads 18, which are connected to one side of the aeration disc 2.

[0030] In the above embodiments, by setting liquid level beads 18 on one side of the aeration disc 2, the horizontal state of the aeration disc 2 is presented intuitively and quantitatively through the position of the liquid bubbles. Installers can observe and judge the tilt of the aeration disc 2 in real time during the adjustment process without the need for external level measuring tools, which greatly improves the convenience and accuracy of level adjustment and makes the installation process standardized and visualized.

[0031] Specifically, it also includes bolts 21, sealing rings 22, slots 23 and sealing strips 24. The pipe clamp 5 includes an upper clamp 19 and a lower clamp 20. The upper clamp 19 and the lower clamp 20 are connected by bolts 21. The connecting pipe 6 is integrally connected to the upper clamp 19. The stud 14 is connected to the upper clamp 19. The sealing ring 22 is sleeved on the lower side of the connecting pipe 6. Slots 23 are opened on both sides of the upper clamp 19. The sealing strip 24 is connected in the slots 23.

[0032] In the above embodiments, by designing the pipe clamp 5 as an engaging structure of upper clamp 19 and lower clamp 20 and locking it with bolt 21, a reliable clamping with the pipe 1 is achieved, making installation convenient. A sealing ring 22 is fitted on the lower side of the connecting pipe 6 to effectively seal the gap between the outer wall of the connecting pipe 6 and the inner wall of the mounting hole 4. At the same time, a slot 23 is opened on the inner side of the upper clamp 19 and a sealing strip 24 is embedded therein, which fits against the outer wall of the pipe 1 to form a double seal.

[0033] The working principle of this utility model is as follows: During installation, first drill the installation hole 4 at the predetermined position above the PVC air distribution pipe 1 at the bottom of the aeration tank (it can be pre-processed in the factory or drilled on site according to the actual pipe layout). Align the connecting pipe 6 on the upper clamp 19 with the mounting hole 4 and insert it from top to bottom. At this time, the sealing ring 22 fitted on the lower side of the connecting pipe 6 is deformed by pressure, sealing the annular gap between the outer wall of the connecting pipe 6 and the inner wall of the mounting hole 4. At the same time, the sealing strip 24 on the inner side of the upper clamp 19 adheres to the outer wall surface of the pipe 1. Together, they form a reliable seal for the position of the mounting hole 4. Then, align the lower clamp 20 with the upper clamp 19 and lock it with the bolt 21 so that the pipe clamp 5 hugs the pipe 1, completing the fixed connection between the connecting pipe 6 and the pipe 1. Fit the arc-shaped sleeve 11 onto the arc-shaped rod 10, align the insertion pipe 8 connected to the lower end of the telescopic hose 7 with the upper port of the connecting pipe 6, and align the screw sleeve 13 with the studs 14 on both sides of the upper clamp 19. The screw sleeve 13 can slide relative to the support rod 12. Tighten the screw sleeve 13 and the studs 14 by rotating the screw sleeve 13. Rotate the rotating sleeve 9 to tighten it with the thread on the outside of the connecting pipe 6. During the tightening process, the rotating sleeve 9 rotates freely relative to the insertion pipe 8, thereby pressing the insertion pipe 8 into the connecting pipe 6 and squeezing the sealing ring 17 to form an end face seal. Then, leveling is adjusted: observe the liquid level bead 18 on one side of the aeration disc 2, and at the same time, apply a rotational force to the aeration disc 2 along the axis of the pipe 1, so that the arc rod 10 slides in the arc sleeve 11, thereby driving the aeration disc 2 to rotate around the axis of the pipe 1. During this process, the telescopic hose 7 undergoes corresponding bending and torsional deformation to compensate for the angular deviation of the mounting hole 4. When the liquid level bead 18 indicates that the aeration disc 2 has reached a horizontal state, tighten the locking screw 15 so that it passes through the arc sleeve 11 and abuts against the arc rod 10, locking the relative position of the arc rod 10 and the arc sleeve 11, thereby fixing the angle of the aeration disc 2.

[0034] It should be noted that the telescopic hose 7 is made of a material with good corrosion resistance and flexibility (such as EPDM rubber or polyurethane) to ensure that it can be repeatedly bent and twisted without breaking under long-term immersion environment and maintain good airtight performance; the inner diameter of the arc sleeve 11 is slightly larger than the outer diameter of the arc rod 10, and a certain compensation gap is reserved between the two, which allows the arc rod 10 to have a certain amount of movement when sliding in the arc sleeve 11.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
