Description

Technical Field

[0001] This invention relates to the technical field of wastewater treatment, and in particular to a high-efficiency aeration device for wastewater purification. Background Technology

[0002] Wastewater treatment is a crucial link in the research and experimental development of environmental protection technologies. Wastewater treatment mainly includes processes such as aeration, flocculation, and sedimentation. Aeration involves introducing air into the wastewater through specific equipment to increase the oxygen content in the wastewater, providing oxygen for microorganisms in the wastewater and improving the efficiency of microorganisms in degrading impurities in the wastewater.

[0003] For example, a sewage tank aeration device with publication number CN116161807B includes a sewage tank, a spray pipe frame, ring nozzles, a high-pressure air pump, etc.; the sewage tank has a rectangular structure; the spray pipe frame is placed inside the sewage tank; several ring nozzles are connected to the spray pipe frame; the high-pressure air pump is located on the lower part of the outer wall of the sewage tank.

[0004] Existing aeration devices can only achieve fixed or unidirectional aeration. In actual use, the aeration coverage is limited, which can easily create aeration dead zones. This results in incomplete decomposition of organic matter and pollutants in the wastewater. At the same time, scum and solid pollutants in the wastewater can easily adhere to the surface of the aeration head, causing blockage and affecting the aeration effect.

[0005] For example, in the aforementioned prior art, the device uses a nozzle frame with ring nozzles, which can only achieve longitudinal aeration in the aeration tank. This results in obvious aeration dead zones during aeration, making it impossible to achieve full coverage. At the same time, it cannot disperse the floating scum on the surface of the sewage or stir up the impurities deposited at the bottom, resulting in insufficient contact between pollutants, oxygen, and microorganisms in the aeration tank, thus affecting the aeration effect.

[0006] Therefore, there is an urgent need to design a high-efficiency aeration device for wastewater purification to solve the above problems. Summary of the Invention

[0018] This invention provides a high-efficiency aeration device for wastewater purification. It has the following beneficial effects: 1. When this aeration device aerates wastewater: the two swing rods of the swing assembly drive the aeration pipe to move horizontally and swing back and forth synchronously, so that the aeration pipe can move back and forth continuously in the wastewater during the aeration process, achieving aeration of the wastewater in the aeration tank without dead angles.

[0019] 2. This aeration device treats wastewater by aeration: When the aeration pipe is located on the surface of the wastewater, it can effectively disperse the floating scum and impurities on the surface of the wastewater, allowing the microorganisms in the wastewater to fully contact with the oxygen in the air, thus promoting the oxidation and decomposition rate of impurities in the wastewater by the microorganisms. When the aeration pipe sinks to the bottom of the pool, it can disperse the deposited solid impurities, allowing the microorganisms attached to the impurities to fully contact with the aeration gas, thus greatly improving the efficiency of wastewater purification.

[0020] 3. When this aeration device treats wastewater: During the aeration process, the rotating frame rotates around the aeration pipe, which, together with the scraper, removes impurities from the surface of the arc-shaped aeration head, preventing clogging. It can also work with the guide plate to direct the gas sprayed from the arc-shaped aeration head to the deeper layers of the aeration tank, aerating deeper layers of wastewater. This effectively increases the aeration depth and coverage, ensuring that the area around the sediment at the bottom of the tank also receives sufficient oxygen, promoting full contact and reaction between pollutants and microorganisms.

[0021] 4. When this aeration device treats wastewater, it can pre-treat the gas required for aeration through the cooperation of the filtration mechanism. The air inlet and the filter plate can deeply filter fine impurities such as dust and particulate matter in the air, preventing impurities from entering the arc-shaped aeration head and causing blockage, and ensuring that the aeration components can still operate stably in complex external environments. In summary, this invention uses an aeration component that moves and swings back and forth in the aeration tank to aerate the wastewater in all directions, avoiding the formation of aeration dead zones during the aeration process. At the same time, the swinging motion can disperse floating debris on the surface of the wastewater, allowing the wastewater to come into contact with the outside air, and can also disperse solid impurities deposited at the bottom, promoting full contact between the microorganisms attached to the impurities and the aeration gas, thereby accelerating the reaction rate.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Example 1: Refer to Figures 1-4 Several fixed frames 2 are set on the upper part of the aeration tank 1, and the power chamber 3 is fixedly connected to the multiple fixed frames 2. Aeration tank 1 is used to hold sewage samples collected outdoors, providing space for aeration reaction and pollutant degradation detection; the fixing frame 2 is used to support the power chamber 3. This aeration device also includes: The moving unit, located inside the power chamber 3, includes a swing assembly, a horizontal movement assembly, and a transmission assembly; The active unit drives the aeration components to move flexibly within the aeration tank 1 through a composite motion mode, fully covering the aeration tank 1 and avoiding the formation of aeration dead zones. At the same time, during the movement, it can break up the scum on the surface of the sewage and stir up the impurities deposited at the bottom of the aeration tank 1, promoting full contact and reaction between pollutants, oxygen and microorganisms in the sewage.

[0027] The swing assembly is provided with two swing rods 6 for reciprocating swing, the horizontal movement assembly is provided with a bidirectional lead screw 18 for driving the swing rods 6 to reciprocate, and the transmission assembly is provided with a second transmission rod 14 for transmitting power. Two first air pipes 21 are respectively set at one end of two swing rods 6, and aeration components are set on them. The aeration components are equipped with multiple arc-shaped aeration heads 25 for aeration. The filter chamber 31 is located on the power chamber 3, and a gas delivery assembly is installed on it. The gas delivery assembly contains a gas pump 39 for delivering gas.

It is easy to operate, requires minimal operator intervention, and has a high degree of automation.

[0029] Example 2: Refer to Figures 5-10 The technical solution that differs from that of Embodiment 1 is that the swing assembly includes a first limiting rod 5 fixedly installed inside the power chamber 3, and two swing rods 6 are both sleeved on the first limiting rod 5. The first limiting rod 5 is used to provide a rotation fulcrum for the two swing rods 6 to ensure the stability of the movement of the swing rods 6 when they swing back and forth. The first transmission rod 11 is rotatably mounted in the power chamber 3 via a support frame, and both ends of the first transmission rod 11 are fixedly mounted with limit telescopic rods 10. Each limit telescopic rod 10 is fixedly mounted with a turntable 7. The limit telescopic rod 10 is used to extend and retract synchronously with the horizontal movement of the turntable 7, ensuring that the power of the first transmission rod 11 can still be transmitted to the turntable 7 during the horizontal movement. A second limiting rod 8 is fixedly installed on each of the two turntables 7. A slot 9 is opened on each of the two swing rods 6 to be sleeved and connected to the second limiting rod 8. A dustproof cloth 44 is provided at the bottom of the power chamber 3 to prevent sewage from entering the power chamber 3. The second limiting rod 8 pushes the slot 9 to convert the rotational motion of the turntable 7 into the swaying motion of the swing rod 6. The dustproof cloth 44 is folded or unfolded as the swing rod 6 moves horizontally, in order to prevent splashing sewage from entering the power chamber 3 during aeration and to prevent the parts from being corroded and damaged by sewage.

[0030] In a further embodiment, the horizontal moving component includes a rotary motor 19 fixedly mounted on the power chamber 3, a bidirectional lead screw 18 rotatably connected inside the power chamber 3, and the driving end of the rotary motor 19 passes through the power chamber 3 and is fixedly connected to one end of the bidirectional lead screw 18. The rotary motor 19 is used to provide power for the rotation of the bidirectional lead screw 18. The bidirectional lead screw 18 has two symmetrically arranged connecting plates 17 threadedly engaged, and both connecting plates 17 are rotatably connected to one side of the turntable 7. The two ends of the bidirectional lead screw 18 are provided with opposite threads, and the opposite threads drive the two connecting plates 17 to move synchronously in opposite directions, thereby realizing the horizontal reciprocating motion of the aeration component.

[0031] In a further embodiment, the transmission assembly includes a fixed rod 13 fixedly connected to the top of the power chamber 3, a second transmission rod 14 rotatably connected to the fixed rod 13, the fixed rod 13 being used to provide a rotation support point for the second transmission rod 14 to ensure structural stability during transmission, a fourth helical gear 20 fixedly connected to the middle section of the bidirectional lead screw 18, the middle section of the bidirectional lead screw 18 being a smooth rod without threads, and the fourth helical gear 20 being fixed on the smooth rod, a first helical gear 12 fixedly connected to the first transmission rod 11, and a third helical gear 16 and a second helical gear 15 fixedly connected to both ends of the second transmission rod 14, the third helical gear 16 meshing with the fourth helical gear 20, and the second helical gear 15 meshing with the first helical gear 12; Through the meshing of the first helical gear 12 with the second helical gear 15, and the meshing of the third helical gear 16 with the fourth helical gear 20, the rotational power of the bidirectional lead screw 18 is sequentially transmitted to the second transmission rod 14, the first transmission rod 11, and the limiting telescopic rod 10, and the power is efficiently transmitted to the turntable 7 through the limiting telescopic rod 10, causing the turntable 7 to rotate synchronously.

[0032] Example 3: Refer to Figures 11-16 The technical difference between this embodiment and embodiment two is that: the aeration assembly includes a sealing bearing 22 disposed at one end of the two first air pipes 21, and each of the two sealing bearings 22 is provided with a five-way connector 23. The sealing bearing 22 is used to seal the connection between the five-way connector 23 and the first air pipe 21, so that gas will not leak from the connection during the rotation of the five-way connector 23. The five connectors on the two five-way connectors 23 are all fixedly connected to the aeration pipe 24, and multiple arc-shaped aeration heads 25 are all fixedly connected to the corresponding aeration pipe 24, and the multiple arc-shaped aeration heads 25 on each aeration pipe 24 face the same direction; The arc-shaped aeration head 25 is used to spray gas from the aeration pipe 24 to aerate the sewage. The arc-shaped aeration head 25 on each aeration pipe 24 faces the same direction. The directional sprayed gas will generate a reverse thrust. This reverse thrust acts on the aeration pipe 24, thereby driving the aeration pipe 24 to drive the five-way connector 23 to rotate on the sealed bearing 22.

[0033] In a further embodiment, each aeration pipe 24 is provided with a plurality of guiding scraping mechanisms for guiding the airflow direction. The guiding scraping mechanism includes a plurality of rotating frames 26 rotatably connected to each aeration pipe 24. The rotating frames 26 can rotate around the aeration pipe 24 to provide a mounting carrier for the guiding scraping mechanism and realize the anti-clogging and gas guiding functions of the arc-shaped aeration head 25. Each rotating frame 26 is fixedly equipped with several scraper blades 27 for scraping off impurities from the surface of the arc-shaped aeration head 25. The scraper blades 27 are in contact with the surface of the arc-shaped aeration head 25. When the rotating frame 26 rotates, it drives the scraper blades 27 to scrape off the scum and impurities attached to the surface of the arc-shaped aeration head 25, so as to avoid clogging of the aeration head. Each rotating frame 26 is fixedly equipped with several guide plates 28 for changing the airflow direction. The guide plates 28 can change the direction of the airflow sprayed from the arc-shaped aeration head 25, and guide the airflow to the depth of the aeration tank 1, so as to ensure that the impurities deposited at the bottom of the aeration tank 1 can also obtain sufficient oxygen and improve the aeration depth. The guide plate 28 is provided with several air guide holes 30 for guiding airflow. The function of the air guide holes 30 is that when the guide plate 28 is in the nozzle position of the arc-shaped aeration head 25, it can allow some of the gas sprayed from the arc-shaped aeration head 25 to accurately pass through the air guide holes 30 without obstructing the aeration gas from changing the airflow direction through the guide plate 28, thereby forming a directional airflow thrust. This thrust can continue to drive the rotation of the aeration pipe 24, preventing the rotation from stopping due to the obstruction of the guide plate 28.

[0034] Several arc-shaped push plates 29 are fixedly connected to the rotating frame 26, which convert the water flow thrust into the rotational power of the rotating frame 26. The arc-shaped push plates 29 utilize the rotational torque formed by the thrust of the aeration airflow and the water flow resistance. This rotational torque drives the rotating frame 26 to rotate automatically without the need for an additional power source, thereby achieving the scraping of impurities attached to the surface of the arc-shaped aeration head 25 by the scraper 27 and the guiding of the sprayed gas by the guide plate 28.

[0035] In a further embodiment, the gas delivery assembly includes an air pump 39 fixedly installed inside the power chamber 3. The air pump 39 is used to pressurize the gas and increase the gas flow rate. The air inlet of the air pump 39 is fixedly connected to a first gas delivery pipe 38. One end of the first gas delivery pipe 38 is connected to the air inlet of the air pump 39, and the other end is connected to the filter chamber 31, which is used to deliver the filtered clean air to the air pump 39 for pressurization. The exhaust port of the air pump 39 is fixedly connected to a second air supply pipe 40. Two telescopic air pipes 41 are fixedly connected to the second air supply pipe 40, and each telescopic air pipe 41 is fixedly connected to a corresponding first air pipe 21. The second air supply pipe 40 and the telescopic air pipes 41 are used to transport the gas pressurized by the air pump 39 to the first air pipe 21 to realize the transportation of aeration gas. The telescopic air pipes 41 can extend and retract synchronously with the horizontal movement and sway of the aeration component to ensure that there is no leakage or pulling during the gas transportation process, and adapt to the needs of complex motion.

[0036] In a further embodiment, a filter chamber 31 is fixedly installed on one side of the power chamber 3. The filter chamber 31 is equipped with an air filtration mechanism and provides installation space for the filtration mechanism. The filtration mechanism includes a partition 32 fixedly installed inside the filter chamber 31. The partition 32 is used to separate the filtration area from the airflow channel. Several filter plates 33 for filtering dust are provided on the partition 32. The filter plates 33 are used to perform deep filtration of air to prevent dust and particulate matter from entering the aeration channel and causing blockage. One end of the first air supply pipe 38 is fixedly connected to one side of the filter chamber 31. Several air inlet holes 37 for air intake are opened on the filter chamber 31.

[0037] In a further embodiment, the partition 32 is provided with a cleaning component for cleaning the filter plate 33. The cleaning component includes a third transmission rod 34 rotatably connected to the partition 32. A brush 35 is fixedly installed on the third transmission rod 34. One end of the third transmission rod 34 passes through the partition 32 and the first air supply pipe 38 in sequence and is fixedly connected to one end of the bidirectional lead screw 18. The third transmission rod 34 is used to transmit the rotational power of the bidirectional lead screw 18 to the brush 35, so that the brush 35 can rotate with the rotation of the bidirectional lead screw 18. The brush 35 is used to clean the impurities attached to the surface of the filter plate 33, avoid clogging of the filter plate 33, and ensure smooth outdoor air intake. Two toothed combs 36 are fixedly installed on the partition plate 32 for cleaning impurities on the brush 35. The toothed combs 36 are used to scrape off the impurities attached to the brush 35 and prevent the impurities from being re-attached to the filter plate 33. A collection port 42 is opened at the bottom of the filter chamber 31. A collection chamber 43 for collecting impurities is slidably connected to the collection port 42. The collection chamber 43 is used to collect the impurities scraped off by the toothed combs 36. It can be pulled out for cleaning at any time and is easy to maintain. During aeration, the brush 35 transfers impurities to the comb 36. These impurities adhere to the surface of the comb 36 under the action of airflow. After aeration is completed, there is no longer any airflow to restrict the impurities, and the impurities fall into the collection chamber 43 under the action of gravity.

[0038] The specific working principle of this aeration device is as follows: The operator injects the wastewater to be aerated into aeration tank 1. Then, the operator inputs parameters such as aeration time and horizontal movement frequency through the control panel on the fixed frame 2. The control panel transmits the signal to the PLC controller, which then issues start, stop and run commands in a synchronized manner to realize the automated coordinated operation of the moving unit, aeration components and air supply components. Then, the air pump 39 is started. The air pump 39 draws in external air through the first air supply pipe 38. The external air enters the filter chamber 31 through the air inlet 37 on the filter chamber 31, and then undergoes deep filtration through the filter plate 33 on the partition 32 to remove dust, particulate matter and other fine impurities. The filtered clean air is pressurized by the air pump 39 and then delivered to the first air pipe 21 through the second air supply pipe 40 and the telescopic air pipe 41. The telescopic air pipe 41 can extend and retract synchronously with the movement of the aeration component to avoid gas leakage or pipe pulling. Pressurized gas is delivered through the first gas pipe 21 to the five-way connector 23 at the sealed bearing 22, and then distributed to five aeration pipes 24. The gas is evenly sprayed out by multiple arc-shaped aeration heads 25 facing the same direction. The sprayed gas aerates the sewage. During the aeration process, the airflow from the arc-shaped aeration heads 25 can drive the aeration pipes 24 to rotate the five-way connector 23 on the sealed bearing 22. During the rotation, the aeration pipes 24 will stir the sewage. During the rotation of the aeration pipe 24, the flow of sewage will act on the arc-shaped push plate 29 on the rotating frame 26. The arc-shaped push plate 29 will form a rotational torque in conjunction with the water flow resistance. This rotational torque will drive the rotating frame 26 to rotate continuously around the aeration pipe 24. When the rotating frame 26 rotates, the scraper 27 on the rotating frame 26 will clean the scum and impurities adhering to the surface of the arc-shaped aeration head 25 in real time to avoid clogging of the aeration head. When the guide plate 28 on the rotating frame 26 is located at the arc-shaped aeration head 25, the guide plate 28 will change the airflow direction and guide the gas sprayed from the arc-shaped aeration head 25 to the depth of the aeration tank 1. At the same time, the air guide hole 30 on the guide plate 28 allows some gas to pass through, forming a directional thrust to assist the continuous rotation of the aeration pipe 24 and prevent the airflow from being blocked, causing the rotation to stop. During this process, the airflow sprayed from the arc-shaped aeration head 25 will also wash the rotating frame 26, reducing the adhesion of sludge. During the aeration of wastewater, the rotating motor 19 is started, which drives the bidirectional lead screw 18 to rotate in both directions. The bidirectional thread of the bidirectional lead screw 18 drives the two connecting plates 17 to move synchronously in opposite directions, thereby driving the turntable 7 to reciprocate horizontally, thus realizing the horizontal reciprocating motion of the aeration component. During the rotation of the bidirectional lead screw 18, the fourth helical gear 20 in the middle section meshes and drives the third helical gear 16 at one end of the second transmission rod 14 to rotate, causing the second transmission rod 14 to rotate on the fixed rod 13. The second helical gear 15 at the other end of the second transmission rod 14 meshes and drives the first helical gear 12 on the first transmission rod 11 to rotate, causing the first transmission rod 11 to rotate. The first transmission rod 11 transmits the rotational power to the turntable 7 through the limiting telescopic rods 10 at both ends, causing the turntable 7 to rotate synchronously. When the turntable 7 rotates, the second limiting rod 8 at its edge slides along the groove 9 of the swing rod 6 and generates a lateral thrust. Since the swing rod 6 is sleeved on the first limiting rod 5, it swings back and forth around the first limiting rod 5 under the action of the thrust, realizing the reciprocating swing motion of the aeration component. Through the combination of horizontal reciprocating motion and reciprocating swaying motion, the aeration components can fully cover the sewage area in aeration tank 1, avoiding aeration dead zones. When the aeration components move to the surface of the sewage, they break up the scum and impurities. When the aeration components move to the bottom of aeration tank 1, they stir up the deposited solid impurities, promoting the full contact and reaction of pollutants with oxygen and microorganisms. During the rotation of the bidirectional lead screw 18, the rotation of the bidirectional lead screw 18 drives the third transmission rod 34 to rotate synchronously. The brush 35 on the third transmission rod 34 cleans the impurities attached to the surface of the filter plate 33, and the toothed comb 36 scrapes off the impurities on the brush 35. The impurities fall into the collection chamber 43, thus realizing the collection of impurities.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
