The porous pipeline device includes a sewage tank, on which a decontamination mechanism is installed. The decontamination mechanism includes an air inlet pipe. To improve the filtration effect of the aeration gas, this porous pipeline device for sewage aeration incorporates a decontamination mechanism. When the gas enters the gas collection box from the air inlet pipe, it undergoes further fine filtration with the help of coarse and dense filter plates. Multiple sets of branch pipes increase the distribution density of the exhaust ports and the gas discharge area. Simultaneously, the filter screen breaks the gas into multiple small bubbles, allowing the gas to contact the sewage over a wider range and at more angles, thereby improving the gas-liquid mixing effect.

Description

Technical Field

[0001] This utility model relates to the field of pipeline device technology, specifically a porous pipeline device for sewage aeration. Background Technology

[0002] Wastewater aeration is a core component of wastewater treatment processes. Essentially, it involves introducing air into the wastewater to provide dissolved oxygen for aerobic microorganisms, thereby promoting the degradation of organic matter by these microorganisms and purifying the water. The efficiency of the aeration system directly affects the wastewater treatment effect, energy consumption, and operating costs. As a key component of the aeration system, the structural design and performance optimization of the aeration device have always been a focus of industry research.

[0003] Traditional aeration devices often lack effective gas filtration structures. Before entering the sewage, the aeration gas is not adequately filtered, and impurities and particulate matter carried in the gas can directly enter the sewage, potentially clogging the holes in the aeration pipes, leading to uneven aeration and reduced aeration efficiency. At the same time, the bubbles formed after the gas is discharged are relatively large, with a small contact area and a single contact angle with the sewage. This results in insufficient reaction between the gas and pollutants in the sewage, preventing microorganisms from obtaining a sufficient and efficient oxygen supply, making it difficult for them to fully exert their decomposition and metabolism functions, and significantly reducing the sewage treatment effect.

[0004] In view of this, we propose a porous pipe device for wastewater aeration. Utility Model Content

[0005] The purpose of this invention is to provide a porous pipe device for sewage aeration to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A porous pipe device for wastewater aeration includes a wastewater tank, on which a decontamination mechanism is provided, the decontamination mechanism comprising:

[0008] An air inlet pipe is fixedly installed on the inner side wall of the sewage tank. The air outlet end of the air inlet pipe is fixedly installed inside the top of the air collection box. A coarse filter plate is snapped into the top of the air collection box, and a dense filter plate is snapped into the bottom of the air collection box.

[0009] An exhaust pipe is fixedly installed on the bottom side wall of the air collection box, and a branch pipe is fixedly installed inside the arc-shaped outer wall of the exhaust pipe. An air outlet is opened on the top side wall of the branch pipe.

[0010] A conical hood, wherein the top end of the bronchus is fixedly installed on the inner wall of the top end of the conical hood, and a filter screen is sleeved on the outer wall of the bronchus, and the outer wall of the filter screen is fixedly installed on the inner wall of the conical hood.

[0011] In a further embodiment, the intake pipe is provided in two sets, and the exhaust pipe is provided in two sets.

[0012] In a further embodiment, multiple sets of branch pipes are provided on a single exhaust pipe, resulting in better exhaust performance and thus better wastewater treatment.

[0013] In a further embodiment, the top of the conical cover is conical.

[0014] In a further embodiment, an auxiliary mechanism is provided on the sewage tank. The auxiliary mechanism includes an asynchronous motor. The asynchronous motor is fixedly installed on the outer wall of the sewage tank. A drive gear is fixedly installed at the output end of the asynchronous motor. The outer wall of the drive gear meshes with the outer wall of the driven gear. A rotating rod is fixedly installed inside the driven gear. A rectangular frame is fixedly installed on the outer wall of the rotating rod. A baffle is fixedly installed on the top of the outer wall of the sewage tank. The bottom end of the baffle is slidably installed on the top of a rack. The bottom end of the rack meshes with the outer wall of the driven gear.

[0015] In a further embodiment, multiple sets of the driven gear, rotating rod, and rectangular frame are provided.

[0016] In a further embodiment, one end of the rectangular frame is tapered.

[0017] Compared with the prior art, this utility model provides a porous pipe device for sewage aeration, which has the following beneficial effects:

[0018] 1. This porous pipe device for wastewater aeration improves the filtration effect of aeration gas by incorporating a decontamination mechanism. After the gas enters the gas collection box from the inlet pipe, it undergoes further fine filtration with the help of coarse and dense filter plates. By setting multiple sets of branch pipes, the distribution density of the exhaust ports and the gas discharge area are increased. At the same time, the filter screen breaks the gas into multiple small bubbles, allowing the gas to contact the wastewater over a wider range and at more angles, thereby improving the gas-liquid mixing effect. In addition, the conical design of the conical hood makes it difficult for impurities in the water to adhere and accumulate near the top of the branch pipe. Instead, they slide down the slope under the action of water flow, ensuring the stable operation of the device.

[0019] 2. This porous pipe device for wastewater aeration, in order to flexibly control the residence and discharge of gas in wastewater and enhance the wastewater treatment effect, is equipped with an asynchronous motor, driving gear, driven gear, rotating rod, and rectangular frame in the auxiliary mechanism. After the air is discharged from the branch pipe, it floats upward and is intercepted by the rotating rectangular frame, forcing the gas to prolong its residence time in the wastewater and fully contact and react with the wastewater. When the air no longer needs to stay, the asynchronous motor drives the driving gear, which in turn drives the driven gear and rotating rod, causing the rectangular frame to rotate and quickly discharge the intercepted air into the wastewater. This achieves flexible control of the aeration process, thereby effectively improving the quality and efficiency of wastewater treatment. Attached Figure Description

[0031] Please see Figures 1-5 This utility model provides a technical solution:

[0032] A porous pipe device for sewage aeration includes a sewage tank 1.

[0033] In one embodiment of this utility model, a decontamination mechanism 2 is provided on the sewage tank 1. The decontamination mechanism 2 includes an air inlet pipe 21, and two sets of air inlet pipes 21 are provided. The air inlet pipe 21 is fixedly installed on the inner side wall of the sewage tank 1. The air outlet end of the air inlet pipe 21 is fixedly installed inside the top of the air collection box 22. A coarse filter plate 23 is snapped into the top of the air collection box 22. A dense filter plate 24 is snapped into the bottom of the air collection box 22. An exhaust pipe 25 is fixedly installed on the bottom side wall of the air collection box 22. Two sets of exhaust pipes 25 are provided. A branch pipe 26 is fixedly installed inside the arc-shaped outer wall of the exhaust pipe 25. Multiple sets of branch pipes 26 are provided on a single set of exhaust pipes 25. An air outlet hole 27 is opened on the top side wall of the branch pipe 26. The top of the branch pipe 26 is fixedly installed on the inner wall of the top of the conical cover 28. The top of the conical cover 28 is conical. A filter screen 29 is sleeved on the outer wall of the branch pipe 26. The outer wall of the filter screen 29 is fixedly installed on the inner wall of the conical cover 28.

[0034] In this embodiment, the aeration gas enters through the inlet pipe 21. Because two sets of inlet pipes 21 are provided, a stable gas input is ensured. After entering the gas collection box 22, the gas first passes through the coarse filter plate 23, which performs preliminary filtration of larger particulate impurities in the gas, blocking larger dust clumps, debris, and other impurities. Then, the gas continues to flow downwards and undergoes fine filtration through the dense filter plate 24. The dense filter plate 24 has a smaller pore size, which can intercept finer particles, suspended matter, and some harmful impurities in the gas, further purifying the gas. The filtered pure gas enters the exhaust pipe 25. Similarly, the two sets of exhaust pipes 25 act as a diversion mechanism, evenly distributing the gas to multiple sets of branch pipes 26 installed inside their arc-shaped outer walls. The air outlet 27 on the top allows gas to be discharged. At this time, the filter screen 29 on the outer wall of the branch pipe 26 plays its role, cutting the discharged gas into countless small bubbles. The shape of the small bubbles greatly increases the contact area and contact angle between the gas and the sewage, allowing the gas to mix fully with the sewage over a wider range and at more angles, improving aeration efficiency and promoting the reaction between pollutants in the sewage and the gas. In addition, the conical cover 28 fixedly installed at the top of the branch pipe 26 has a conical top. When impurities in the water approach the top of the branch pipe 26 under the action of water flow, due to the inclined structure of the cone, the impurities cannot adhere and accumulate at the top of the branch pipe 26. Instead, they will slide down the inclined surface under the push of the water flow, preventing the branch pipe 26 from being blocked and ensuring the long-term stable operation of the device.

[0035] In one embodiment of this utility model, an auxiliary mechanism 3 is provided on the sewage tank 1. The auxiliary mechanism 3 includes an asynchronous motor 31. The asynchronous motor 31 is fixedly installed on the outer wall of the sewage tank 1. A drive gear 32 is fixedly installed at the output end of the asynchronous motor 31. The outer wall of the drive gear 32 meshes with the outer wall of the driven gear 33. A rotating rod 34 is fixedly installed inside the driven gear 33. A rectangular frame 35 is fixedly installed on the outer wall of the rotating rod 34. One end of the rectangular frame 35 is tapered. Multiple sets of driven gears 33, rotating rods 34 and rectangular frames 35 are provided. A baffle 36 is fixedly installed on the top of the outer wall of the sewage tank 1. The bottom end of the baffle 36 is slidably installed on the top end of a rack 37. The bottom end of the rack 37 meshes with the outer wall of the driven gear 33.

[0036] In this embodiment, the air discharged from the bronchus 26, being less dense than the sewage, will naturally float upwards under buoyancy. At this time, the multiple sets of rectangular frames 35 in the sewage tank 1 are stationary. Their cone-shaped, hollow structure acts as an interceptor. The cone shape prevents the accumulation of impurities in the water, while the hollow structure facilitates air entry. When rising air bubbles encounter the rectangular frames 35, they are captured and intercepted by their hollow cavities, preventing them from floating directly to the sewage. Instead, they remain in the sewage, thus extending the contact time with the sewage and allowing for sufficient oxidation and decomposition reactions with various pollutants in the sewage, enhancing the sewage treatment effect. When the sewage treatment process enters the stage where aeration is no longer required, the operator sends a start command to the asynchronous motor 31 through the control system. The asynchronous motor 31 starts running, and its output drive gear 32 follows suit. The rotation, through the gear meshing relationship, drives the driven gear 33, the rotating rod 34, and the rectangular frame 35 fixed to the outer wall of the rotating rod 34 to start rotating. The rotation of the rectangular frame 35 breaks the static state of the air inside it. Under the combined action of centrifugal force and water flow, the air that was originally trapped in the rectangular frame 35 quickly escapes from the rectangular frame 35 and is pushed up and discharged by the water flow. During this process, the baffle 36 fixedly installed on the top of the outer wall of the sewage tank 1 is in close cooperation with the rack 37. The outer wall of the bottom end of the rack 37 and the outer wall of the driven gear 33 always maintain precise meshing, providing stable guidance for the rotation of the driven gear 33, ensuring that the entire auxiliary mechanism 3 remains stable during operation, realizing flexible control of gas retention and discharge during aeration, effectively meeting the needs of different sewage treatment stages, and improving the quality and efficiency of sewage treatment.

The PLC controller is a conventional and known device capable of controlling the asynchronous motor 31. All standard parts used in this application can be purchased from the market.
