Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment equipment, and in particular to an anti-clogging device for compressed air aeration pipes containing muddy liquid. Background Technology

[0002] Compressed air is commonly used for aeration in existing wastewater treatment systems, chemical reaction processes, and waste acid purification. However, when treating sludge-containing liquids (such as wastewater and waste acid), sludge and sediment can easily clog the pores of the aeration pipes, severely affecting aeration efficiency and production effectiveness. Especially during acid regeneration, sediment in the reaction tank can clog the air distribution holes, affecting the efficiency of the oxidation reaction and consequently reducing the waste acid purification effect. In severe cases, this can necessitate shutdown for maintenance, disrupting production continuity. Utility Model Content

[0003] The purpose of this invention is to provide a device for preventing blockage of compressed air aeration pipes containing muddy liquids, which aims to avoid the air holes of the aeration pipes being blocked by sludge or sediment, and to ensure the stable operation of the system.

[0004] According to the purpose of this utility model, this utility model provides a device for preventing blockage of compressed air aeration pipe for muddy liquid, including a wind cap and a needle-shaped anti-blockage device disposed at the air distribution hole on the air distribution pipe of the reaction tank. The wind cap covers the outside of the air distribution hole, and the needle-shaped anti-blockage device penetrates the air distribution hole and is disposed inside the wind cap. The wind cap is provided with an array of exhaust holes. The needle-shaped anti-blockage device generates irregular movement driven by airflow during the aeration process.

[0005] Furthermore, the hood is made of polypropylene material.

[0006] Furthermore, the needle-shaped anti-clogging device is made of titanium.

[0007] Furthermore, the needle-shaped anti-clogging device includes an anti-clogging needle, the tail end of which is provided with a needle claw, and the head end of which is provided with a needle cap.

[0008] Furthermore, the aspect ratio of the anti-blocking needle is 5:1-8:1.

[0009] Furthermore, the diameter of the needle claw is larger than the inner diameter of the air hole, and the diameter of the needle cap is larger than the inner diameter of the air hole.

[0010] Furthermore, the exhaust port array includes a plurality of exhaust ports arranged in an array.

[0011] Furthermore, the diameter of the exhaust port is smaller than the inner diameter of the air distribution port.

[0012] Furthermore, the hood is detachably connected to the air distribution pipe.

[0013] Furthermore, the surface of the anti-clogging pin is provided with a micro-protruding thread structure.

[0014] The technical solution of this utility model utilizes a needle-shaped anti-clogging device that moves irregularly driven by airflow during aeration, automatically scraping away sludge and sediment from the air distribution holes to prevent clogging and reduce the frequency of manual cleaning. The exhaust holes of the air cap optimize airflow distribution, ensuring that compressed air enters the liquid evenly, improving the efficiency of oxidation reactions or wastewater treatment. The movement of the anti-clogging device does not affect the original air velocity and volume, maintaining a stable aeration effect. Attached Figure Description

[0026] Example 1

[0027] like Figures 1-3 As shown, a clogging prevention device for compressed air aeration pipes containing muddy liquid is provided. This device is installed at the air distribution hole 3 on the air distribution pipe 2 of the reaction tank 1. The device includes an air cap 4 and a needle-shaped anti-clogging device 5. The air cap 4 is made of polypropylene (PP) material, and the needle-shaped anti-clogging device 5 is made of titanium (Ti2) material. The needle-shaped anti-clogging device 5 can automatically clean the air distribution hole during aeration, preventing clogging and thus maintaining good gas distribution and aeration effect.

[0028] This invention achieves a self-cleaning function for the aeration pipe holes by designing an anti-clogging system for the air distribution holes. This avoids the need for frequent shutdowns to clean the reaction tank, thereby improving production efficiency and waste acid purification quality. The device can effectively extend the operating time of the reaction tank, reduce the number of shutdowns for maintenance and maintenance costs, and has good economic and technical benefits.

[0029] Example 2

[0030] like Figures 1-5As shown, the structure of this embodiment is basically the same as that of embodiment 1. Specifically, in this embodiment, the diameter of the air distribution hole 3 of the compressed air pipe 2 of the reaction tank 1 is increased from the original Ø4mm to Ø5mm to install the anti-clogging device.

[0031] The vent cap 4 is designed as a kit covering the air vents 3. It is made of PP material, which is corrosion-resistant and can effectively protect the internal needle-shaped anti-clogging device. The vent cap 4 has exhaust holes 6 corresponding to the air vents 3 inside.

[0032] Each air distribution hole 3 has a needle-shaped anti-clogging device 5 installed inside the air cap 4. This needle-shaped anti-clogging device 5 is made of titanium (Ti2), which has strong corrosion resistance and can continuously self-clean the air distribution holes during aeration, preventing the accumulation of sludge and sediment. The needle-shaped anti-clogging device 5 passes through the air distribution hole 3 and is located inside the air cap 4.

[0033] During aeration, due to the airflow, the needle-shaped anti-clogging device 5 moves irregularly within the air distribution hole 3, automatically cleaning up any sediment that may accumulate in the hole, ensuring normal gas distribution and good aeration effect.

[0034] Example 3

[0035] like Figures 1-6 As shown, the structure of this embodiment is basically the same as that of the above embodiment. The difference is that in this embodiment, the anti-clogging device for the compressed air aeration pipe containing muddy liquid includes a wind cap 4 and a needle-shaped anti-clogging device 5. The wind cap 4 is installed outside the air distribution hole 3 of the compressed air pipe, and the needle-shaped anti-clogging device 5 is set inside the wind cap 4 and can automatically clean the air distribution hole during the aeration process.

[0036] The aeration cap 4 is made of polypropylene (PP) material, which is corrosion-resistant. The aeration cap 4 has exhaust holes 6 corresponding to the air distribution holes 3. A needle-shaped anti-clogging device 5 passes through the air distribution holes 3 and is located inside the aeration cap 4. The aeration cap 4 provides space for the needle-shaped anti-clogging device 5 while limiting its range of motion. Simultaneously, the exhaust holes 6 allow compressed air discharged from the air distribution holes 3 to smoothly enter the wastewater, ensuring smooth aeration. The exhaust holes 6 are arranged in an array, and their diameter is smaller than that of the air distribution holes 3, used to evenly disperse the airflow and prevent sludge from entering the interior of the aeration cap 4.

[0037] In this embodiment, the air cap 4 and the air distribution pipe 2 can be detachably connected for easy installation and maintenance. For example, a threaded interface can be provided at the air distribution hole 3, and the bottom of the air cap 4 can be connected to the air distribution pipe 2 via threads.

[0038] The needle-shaped anti-clogging device 5 is made of titanium (Ti2). Specifically, the needle-shaped anti-clogging device 5 is an anti-clogging needle 7 with a length-to-diameter ratio of 5:1-8:1. The head end of the anti-clogging needle 7 is equipped with a needle cap 8, the end of which is hemispherical. The tail end of the anti-clogging needle 7 is equipped with a needle claw 9. The outer diameter of both the needle cap 8 and the needle claw 9 is larger than the inner diameter of the air hole 3, so that the anti-clogging needle 7 will not come out of the air hole 3 during movement.

[0039] In this embodiment, the surface of the anti-clogging needle 7 is provided with a slightly raised threaded structure, which enhances the scraping and cleaning effect of the anti-clogging needle 7 on the inner wall of the air hole 3 during the movement.

[0040] In this embodiment, the diameter of the air distribution hole is Ø5mm. The needle-shaped anti-clogging device can move randomly during aeration, thereby self-cleaning the air distribution hole. The length of the needle-shaped anti-clogging device is suitable for movement within the air distribution hole and for cleaning sediment. The anti-clogging device is suitable for reaction tanks in industries such as acid regeneration, wastewater treatment, and slurry treatment. The anti-clogging device does not change the original gas velocity and volume during aeration. The anti-clogging device can avoid uneven aeration and production downtime caused by clogging. The anti-clogging device can effectively reduce maintenance costs caused by downtime for cleaning. The anti-clogging device is easy to install and can be installed without downtime for maintenance. The design of the air cap and the needle-shaped anti-clogging device can ensure the normal working condition of the aeration pipe and good gas distribution. The anti-clogging device can extend the operating cycle of the reaction tank and reduce the number of downtime cleanings. The anti-clogging device is suitable for various industries and processes, especially in the reaction process of treating muddy liquids.

[0041] Example 4

[0042] This novel anti-clogging device has been applied in the acid regeneration production of a steel plant. The modified acid regeneration reactor only requires sludge cleaning once a year, avoiding the previous problem of multiple annual shutdowns for cleaning. Since the modification, acid regeneration production has been running smoothly, and the quality of iron oxide red has not been affected by blockages in the gas distribution pipe.

[0043] The anti-clogging device of this invention does not affect the gas distribution of compressed air, nor does it change the original air velocity and volume. When the air velocity and volume change instantaneously, the anti-clogging needle moves randomly within the orifice, thereby automatically cleaning the orifice. Because the waste acid is corrosive, the air cap is made of PP material, and the needle is made of titanium.

[0044] By using an anti-clogging device, the aeration holes achieve a self-cleaning function, which not only improves the start-up efficiency of production but also enhances the quality of purified waste acid. It avoids frequent shutdowns for cleaning the reaction tank, ensuring stable operation of the production system and reducing costs associated with downtime.

[0045] This utility model relates to an anti-clogging device for compressed air aeration pipes containing muddy liquids. A needle-shaped anti-clogging device, driven by airflow during aeration, moves irregularly to automatically scrape away sludge and sediment from the air distribution holes, preventing blockages and reducing the frequency of manual cleaning. The exhaust port of the air cap optimizes airflow distribution, ensuring uniform compressed air entry into the liquid and improving oxidation reaction or wastewater treatment efficiency. The movement of the anti-clogging device does not affect the original air velocity and volume, maintaining a stable aeration effect.

[0046] This utility model equipment uses corrosion-resistant PP air caps and titanium alloy (Ti2) anti-clogging needles, making it suitable for acidic and highly polluted environments, reducing equipment corrosion and wear. It minimizes downtime for maintenance due to blockages, extending the service life of reaction tanks and aeration pipes. It is applicable to various aeration scenarios involving muddy liquids, such as wastewater treatment, acid regeneration, and slurry treatment, demonstrating strong versatility.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
