Description

Technical Field

[0001] This invention relates to the field of aeration technology, and more specifically to a biological aeration device for water environment remediation. Background Technology

[0002] Aeration generates and promotes the effective contact of oxygen with water. When biological oxidation continuously consumes oxygen, it provides oxygen to maintain a certain dissolved oxygen concentration in the water. In addition to supplying oxygen, the aeration tank area can also generate sufficient stirring and mixing to promote the circulation of water.

[0003] Some existing aeration equipment requires the installation of aeration pipes at the bottom of the pool, which is costly and requires initial planning. Another approach involves using a surge pump and aerator in combination. The surge pump has a strong agitation ability, mixing the upper and lower layers of water. However, when used at night or on rainy days, it stirs up low-oxygen water and oxygen-consuming substances from the bottom layer to the top. Even though the upper layer water is not oxygen-deficient, turning on the surge pump causes a drop in dissolved oxygen throughout the water. In this situation, a float head aerator is activated. Based on the working principle of aerators, targeted use of aerators is crucial, especially on sunny days. The oxygen deficiency the following morning is mainly due to the large vertical variation in dissolved oxygen between the upper and lower water layers during the day. During the day, the lower water layer has a higher temperature and density, while the upper water layer has a higher temperature and lower density. The upper and lower water layers cannot convect in time, and the supersaturated oxygen in the upper layer escapes to the surface and is wasted. Meanwhile, the lower layer has more oxygen-consuming factors. When the surface water temperature drops and the density increases at night, causing convection between the upper and lower water layers, the dissolved oxygen conditions of the entire water layer often deteriorate, leading to surface surfacing. Similarly, the above-mentioned equipment usually needs to be installed at the bottom of the water, which makes it difficult to adjust the aeration area and results in high aeration costs. Summary of the Invention

[0004] To overcome the aforementioned technical problems, the present invention aims to provide a biological aeration device for water environment remediation. By installing a sleeve on one side of the housing, the angle of two guide cylinders can be adjusted simultaneously by rotating a handwheel when changing the aerator area. This increases the spacing between the aeration pipes near the water surface, initially adjusting the aeration area. When the inner rod extends, two limiting rings fit onto the aeration pipes, allowing the counterweight module to hang on them, further preventing the counterweight module from separating from the aeration pipes due to imbalance. The rotatable limiting wheel acts as a guide when the inner rod pushes the first wheel frame along the limiting frame, allowing adjustment of the spacing between the aeration pipes near the bottom, thus adjusting the aeration area. Simultaneously, a stepper motor can be activated to reduce the amount of aeration pipe wound on the winding drum, increasing the length of the aeration pipe in the water, further adjusting the aeration area. Therefore, the aeration area of ​​the device can be adjusted according to actual conditions, improving the device's applicability and saving aeration costs.

One end of the worm is fixedly connected to a handwheel.

[0010] Furthermore, the counterweight module also includes a limiting wheel, a rack, a second wheel frame, and a limiting ring. The second wheel frame is movably connected to the outer surface of the limiting frame. The limiting wheels are rotatably connected to the outer surfaces of both the first and second wheel frames. The limiting ring is fixedly connected to the outer surfaces of the first and second wheel frames. The rack is fixedly connected to the inner surface of the limiting frame.

[0011] Furthermore, a pneumatic push rod is fixedly connected to the inner surface of the second wheel frame near the first wheel frame. An inner rod is movably connected inside the first pneumatic push rod. One end of the inner rod contacts the first wheel frame. A piston is nested and connected to the outer surface of the inner rod. A solenoid reversing valve is fixedly connected to the outer surface of the first pneumatic push rod. A second air supply pipe is embedded and fixedly connected to the outer surface of the aeration pipe. The second air supply pipe and the first solenoid reversing valve are connected and conductive.

[0012] Furthermore, the moving module also includes a second electromagnetic reversing valve, a second pneumatic push rod, a drive frame, and a drive wheel. The second pneumatic push rod is embedded in one side surface of the power box. The second pneumatic push rod has the same structure as the first pneumatic push rod. The inner rod of the second pneumatic push rod is fixedly connected to the drive frame. The drive wheel is rotatably connected inside the power box.

[0014] The beneficial effects of this invention are:

[0015] 1. By installing a sleeve on one side of the housing, the angle of the two guide cylinders can be adjusted simultaneously by turning the handwheel when changing the aerator area. This increases the spacing between the aeration pipes near the water surface, initially adjusting the aeration area. When the inner rod extends, the two limiting rings are placed on the aeration pipes, allowing the counterweight module to hang on them. This further prevents the counterweight module from separating from the aeration pipes due to imbalance. The rotatable limiting wheel acts as a guide when the inner rod pushes the first wheel frame to slide along the limiting frame. At this time, the spacing of the aeration pipes near the bottom can be adjusted to regulate the aeration area. Simultaneously, the stepper motor can be activated to reduce the amount of aeration pipe wound on the winding drum, increasing the length of the aeration pipe in the water, thus adjusting the aeration area. This allows the aeration area of ​​the device to be adjusted according to actual conditions, improving the applicability of the device and saving aeration costs.

[0016] 2. By using the rotating ring of the sleeve, when cleaning the aeration pipe that is easily scraped to the bottom, the No. 2 solenoid directional valve is activated. The gas in the aeration pipe enters the interior of the No. 2 pneumatic push rod through the No. 1 air supply pipe. The No. 2 pneumatic push rod and the No. 2 solenoid directional valve work together to realize the reciprocating motion of the inner rod part of the No. 2 pneumatic push rod, which in turn drives the drive frame to reciprocate. A half-circle driven tooth is fixedly connected to the outer surface of the drive wheel, which works with the driving tooth on the inner surface of the drive frame to realize the rotation of the drive wheel. When the drive wheel rotates, it drives the No. 3 gear and the No. 1 bevel gear, which are coaxial with it, to rotate synchronously. When the No. 3 gear rotates, it drives the moving module and the rotating ring to move along the rack. When the No. 1 bevel gear rotates, it works with the No. 2 bevel gear to drive the rotating ring inside the limit sleeve to rotate. Therefore, the rotatable and movable rotating ring on the outside of the aeration pipe can change the water flow on the outside of that section of the aeration pipe. The direction of the flow creates turbulence on the outside of the aeration pipe, further carrying away debris attached to its surface. Activating the waterproof electric actuator extends its output, altering the distance between the flexible plate and the aeration pipe. Since the center of the rotating ring and the center of the aeration pipe are not aligned, the distance between the adjustable flexible plate and the aeration pipe is irregular during rotation, enhancing the turbulence effect of the flexible plate on the outside of the aeration pipe. Furthermore, the movable module and rotating ring act as weights; when tilted downwards on the second wheel frame side, they can be adjusted towards the first wheel frame side, and vice versa. Combined with the openable guide tube, the adjustable aeration pipe length winding tube, and the adjustable spacing of the second and first wheel frames, the center of gravity of the underwater portion of the device can be adjusted to achieve balance.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-8As shown, a biological aeration device for water environment remediation includes a mounting frame 1. A winding cylinder 2 is rotatably connected to the inner surface of the mounting frame 1, and an aeration pipe 4 is embedded in the outer surface of the winding cylinder 2. An angle adjustment module 3 is provided on the outer surface of the mounting frame 1, through which the aeration pipe 4 passes. A counterweight module 5 is nested on the outer surface of the aeration pipe 4. Mounting holes 101 are provided near the four corners of the lower surface of the mounting frame 1, and aeration holes are provided on the outer surface of the aeration pipe 4. The counterweight module 5 includes a first wheel frame 501 and a limiting frame 503. The limiting frame 503 is fixedly connected to the outer surface of the first wheel frame 501, and a moving module 7 is nested and slidably connected to the outer surface of the limiting frame 503. A first pneumatic push rod 6 is provided on the inner surface of the first wheel frame 501 near the moving module 7. The moving module 7 includes a power box 70. 1. The power box 701 and the limit frame 503 are slidably connected. The front surface of the power box 701 is rotatably connected to the No. 3 gear 8. The device is installed on the hull through the mounting hole 101 on the mounting bracket and the external threaded connector. Then, the air source on the ship and the air pipe rotary joint 202 are connected. Then, the stepper motor 203 is started. The output end of the stepper motor 203 rotates, causing the wound aeration pipe 4 to slide down the guide cylinder 307 into the water. The retractable aeration pipe 4 not only makes it easy to store the aeration pipe 4, but also allows adjustment of the height of the counterweight module 5 in the water, so that the device can be used in water of different depths. When the external air source is started, the external air enters the winding cylinder 2 from the air pipe rotary joint 202, then enters the aeration pipe 4 from the winding cylinder 2, and further enters the water from the aeration pipe 4 to complete the aeration operation.

[0029] A limit plate 201 is fixedly connected to the outer surface of the winding drum 2. A rotary joint 202 for the air pipe is rotatably connected to one end of the winding drum 2. A stepper motor 203 is fixedly connected to the side surface of the mounting frame 1. The output end of the stepper motor 203 is fixedly connected to the winding drum 2. The angle adjustment module 3 includes an adjustment frame 301, a first gear 302, a second gear 303, a worm gear 304, a worm 305, a handwheel 306, and a guide cylinder 307. An adjustment frame 301 is fixedly connected to the front surface of the mounting frame 1. A first gear 302 is rotatably connected to the front surface of the adjustment frame 301. A second gear 303 is rotatably connected to the front surface of the adjustment frame 301 near the first gear 302. The first gear 304... 2. Gear 302 is meshed with gear 303. A worm gear 304 is fixedly connected to the rear surface of gear 302. A worm 305 is rotatably connected to the rear surface of the adjusting frame 301. The worm 305 and the worm gear 304 are meshed. A handwheel 306 is fixedly connected to one end of the worm 305. Rotating the handwheel 306 causes the worm 305 to rotate, which in turn causes the worm gear 304 to drive the gear 302, which is coaxial with it, to rotate. The gear 302 then drives the gear 303, which is meshed with it, to rotate. Therefore, rotating the handwheel 306 can simultaneously adjust the angle of the two guide cylinders 307, thereby increasing the spacing between the aeration pipes 4 near the water surface and initially adjusting the aeration area.

[0030] The counterweight module 5 also includes a limiting wheel 502, a rack 504, a second wheel frame 505, and a limiting ring 506. The second wheel frame 505 is movably connected to the outer surface of the limiting frame 503. The limiting wheel 502 is rotatably connected to the outer surfaces of both the first wheel frame 501 and the second wheel frame 505. The limiting ring 506 is fixedly connected to the outer surfaces of the first wheel frame 501 and the second wheel frame 505. The rack 504 is fixedly connected to the inner surface of the limiting frame 503. A pneumatic push rod 6 is fixedly connected to the inner surface of the second wheel frame 505 near the first wheel frame 501. The pneumatic push rod 6 is internally connected to an inner rod 601, one end of which contacts the first wheel frame 501. A piston 602 is nested on the outer surface of the inner rod 601. A first electromagnetic directional valve 603 is fixedly connected to the outer surface of the first pneumatic push rod 6. A second air supply pipe 402 is embedded and fixedly connected to the outer surface of the aeration pipe 4. The second air supply pipe 402 and the first electromagnetic directional valve 603 are connected and conductive. The moving module 7 also includes a second electromagnetic directional valve 702, a second pneumatic push rod 703, a drive frame 704, and a drive wheel 705. A power box 701 is also included. A second pneumatic push rod 703 is embedded and connected to one side surface of the aeration pipe 4. The second pneumatic push rod 703 has the same structure as the first pneumatic push rod 6. The inner rod 601 of the second pneumatic push rod 703 is fixedly connected to a drive frame 704. A drive wheel 705 is rotatably connected inside the power box 701. A second electromagnetic reversing valve 702 is fixedly connected to the upper surface of the power box 701. A first air supply pipe 401 is embedded and connected to the outer surface of the aeration pipe 4. The first air supply pipe 401 and the second electromagnetic reversing valve 702 are connected and connected. When the second electromagnetic reversing valve 702 is opened, the aeration pipe 4... The gas enters the interior of the second pneumatic push rod 703 through the first gas supply pipe 401. The second pneumatic push rod 703 and the second electromagnetic reversing valve 702 cooperate to realize the reciprocating motion of the inner rod 601 part of the second pneumatic push rod 703, which further drives the drive frame 704 to reciprocate. The outer surface of the drive wheel 705 is fixedly connected with a half-circle driven tooth, which cooperates with the driving tooth on the inner surface of the drive frame 704 to realize the rotation of the drive wheel 705. When the drive wheel 705 rotates, it drives the third gear 8 and the first bevel gear 806, which are coaxial with it, to rotate synchronously.

[0031] Gear No. 3 8 and drive wheel 705 are fixedly connected. A sliding frame 801 is fixedly connected to the front surface of power box 701. The moving module 7 is slidably connected to the sliding frame 801 and the limiting frame 503. A limiting sleeve 802 is fixedly connected to the front surface of sliding frame 801. A rotating ring 803 is rotatably connected inside the limiting sleeve 802. A flexible plate 804 is movably connected inside the rotating ring 803. A waterproof electric push rod 805 is fixedly connected to the rear surface of flexible plate 804. A battery is built into the rotating ring 803. The waterproof electric push rod 805 is electrically connected to the battery. The front surface of gear No. 3 8... A first bevel gear 806 is fixedly connected, and a second bevel gear 807 is fixedly connected to one side surface of the rotating ring 803. The first bevel gear 806 and the second bevel gear 807 are meshed together. A third gear 8 is meshed with a rack 504. When the second solenoid directional valve 702 is activated, the gas in the aeration pipe 4 enters the interior of the second pneumatic push rod 703 through the first air supply pipe 401. The second pneumatic push rod 703 and the second solenoid directional valve 702 cooperate to realize the reciprocating motion of the inner rod 601 part of the second pneumatic push rod 703, which further drives the drive frame 704 to reciprocate, thus driving... A half-circle driven tooth is fixedly connected to the outer surface of wheel 705, which, in conjunction with the driving tooth on the inner surface of drive frame 704, drives wheel 705 to rotate. When wheel 705 rotates, it drives gear 8 (number 3) and bevel gear 806 (number 1) to rotate synchronously. Gear 8 (number 3) rotates, causing moving module 7 and rotating ring 803 to move along rack 504. Conversely, bevel gear 806 (number 1) rotates, in conjunction with bevel gear 807 (number 2), driving rotating ring 803 inside limit sleeve 802 to rotate. Therefore, the rotatable and movable rotating ring 803 outside aeration pipe 4 can... By changing the direction of the water flow outside the aeration pipe 4, the water flow outside the aeration pipe 4 becomes turbulent, further causing the debris attached to the outer surface of the aeration pipe 4 to be carried away by the turbulent water flow. Activating the waterproof electric push rod 805 extends its output end, changing the distance between the flexible plate 804 and the aeration pipe 4. Since the center of the rotating ring 803 and the center of the aeration pipe 4 are not on the same straight line, the distance between the adjustable flexible plate 804 and the aeration pipe 4 is irregular during rotation, which improves the turbulence effect of the flexible plate 804 on the water flow outside the aeration pipe 4.

[0032] Working principle: When in use, the device is installed on the hull A through the mounting hole 101 on the mounting bracket 1 and the external threaded connector. Then, the air source on the ship and the air pipe rotary joint 202 are connected. Then, the stepper motor 203 is started. The output end of the stepper motor 203 rotates, causing the wound aeration pipe 4 to slide down the guide cylinder 307 into the water. The retractable aeration pipe 4 not only makes it easy to store the aeration pipe 4, but also allows the height of the counterweight module 5 in the water to be adjusted, so that the device can be used in water of different depths. When the external air source is started, the external air enters the winding cylinder 2 from the air pipe rotary joint 202, then enters the aeration pipe 4 from the winding cylinder 2, and further enters the water from the aeration pipe 4 to complete the aeration operation.

[0033] When changing the aerator area, rotate the handwheel 306. The handwheel 306 drives the worm gear 305 to rotate, which in turn drives the first gear 302, which is coaxial with the worm gear 304, to rotate. The first gear 302 drives the second gear 303, which is meshed with it, to rotate. Therefore, rotating the handwheel 306 can simultaneously adjust the angle of the two guide cylinders 307, making the spacing between the aeration pipes 4 near the water surface larger, thus initially adjusting the aeration area.

[0034] For the aeration pipe 4 near the bottom of the water, the first electromagnetic reversing valve 603 is activated. Part of the gas in the aeration pipe 4 enters the interior of the first pneumatic push rod 6 through the second air supply pipe 402, squeezing the piston 602 to extend the inner rod 601. The specific connection relationship between the first electromagnetic reversing valve 603 and the first pneumatic push rod 6, and the connection relationship between the second pneumatic push rod 703 and the second electromagnetic reversing valve 702 are consistent with the connection method of telescopic cylinder and reversing valve in the prior art. When the inner rod 601 extends, the two limiting rings 506 are sleeved on the aeration pipe 4, so that the counterweight module 5 is hung on the aeration pipe 4. This further prevents the counterweight module 5 from separating from the aeration pipe 4 due to loss of balance. The rotatable limiting wheel 502 plays a guiding role when the inner rod 601 pushes the first wheel frame 501 to slide along the limiting frame 503. At this time, the distance of the aeration pipe 4 near the bottom of the water can be adjusted to adjust the aeration area and save aeration costs.

[0035] At the same time, the stepper motor 203 can be started to reduce the amount of aeration pipe 4 wound by the winding drum 2 and increase the length of the aeration pipe 4 in the water to adjust the aeration area. This allows the aeration area of ​​the device to be adjusted according to the actual situation, thereby improving the applicability of the device.

[0036] When cleaning the aeration pipe 4, which is easily scraped to the bottom, is required, the second electromagnetic reversing valve 702 is activated. The gas in the aeration pipe 4 enters the interior of the second pneumatic push rod 703 through the first air supply pipe 401. The second pneumatic push rod 703 and the second electromagnetic reversing valve 702 work together to realize the reciprocating motion of the inner rod 601 part of the second pneumatic push rod 703, which further drives the drive frame 704 to reciprocate. The outer surface of the drive wheel 705 is fixedly connected with a half-circle driven tooth, which works with the driving tooth on the inner surface of the drive frame 704 to realize the rotation of the drive wheel 705. When the drive wheel 705 rotates, it drives the third gear 8 and the first bevel gear 806, which are coaxial with it, to rotate synchronously.

[0037] When gear 8 rotates, it drives the moving module 7 and the rotating ring 803 to move along the rack 504. When bevel gear 806 rotates, it works with bevel gear 807 to drive the rotating ring 803 inside the limiting sleeve 802 to rotate. Therefore, the rotatable and movable rotating ring 803 on the outside of the aeration pipe 4 can change the direction of water flow on the outside of the aeration pipe 4, making the water flow on the outside of the aeration pipe 4 turbulent. This further causes the debris attached to the outer surface of the aeration pipe 4 to be carried away by the turbulent water flow. When the waterproof electric push rod 805 is activated, the output end of the waterproof electric push rod 805 can be extended, changing the distance between the flexible plate 804 and the aeration pipe 4. Since the center of the rotating ring 803 and the center of the aeration pipe 4 are not on the same straight line, the distance between the adjustable flexible plate 804 and the aeration pipe 4 is irregular when rotating, which can improve the turbulence effect of the flexible plate 804 on the water flow on the outside of the aeration pipe 4.

[0038] Additionally, the movable module 7 and rotating ring 803 act as weights. When the second wheel frame 505 is tilted downwards, the movable module 7 and rotating ring 803 can be adjusted towards the first wheel frame 501. Conversely, the same applies. With the openable guide tube 307, the adjustable winding tube 2 with adjustable aeration pipe 4 length, and the adjustable spacing of the second wheel frame 505 and the first wheel frame 501, the center of gravity of the underwater part of the device can be adjusted to achieve the balance of the device.
