Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically to an environmentally friendly water treatment aeration device. Background Technology

[0002] Aeration devices play a crucial role in providing the necessary dissolved oxygen for wastewater biological treatment processes and the remediation of polluted water bodies. By efficiently injecting oxygen into the water, they support the effective decomposition and transformation of organic pollutants by aerobic microorganisms. This is an indispensable key technology for achieving water purification, ensuring treatment efficiency, and restoring the ecological health of aquatic bodies.

[0003] Patent CN215712030U discloses an environmentally friendly water treatment aeration device, relating to the field of wastewater treatment technology. It includes a treatment tank with a fixed pipe rotatably mounted on its top. An aerator is connected to the top of the fixed pipe, and the output end of the aerator communicates with the fixed pipe. A U-shaped air outlet pipe is connected to the free end of the fixed pipe. A drive unit is installed on the treatment tank to rotate the fixed pipe. This patent utilizes the drive unit to rotate the fixed pipe, while the U-shaped air outlet pipe connected to the bottom of the fixed pipe agitates the liquid inside the treatment tank, accelerating the contact volume between wastewater and air, increasing the dissolved oxygen efficiency of the wastewater, and reducing the manufacturing cost of the device.

[0004] When the above-mentioned device is used in a cold environment, the water viscosity is likely to increase due to the low temperature, which increases the resistance to the diffusion of oxygen from the bubbles into the water, resulting in a significant decrease in aeration efficiency. The activity of aerobic bacteria is reduced due to the low temperature environment, which in turn leads to a decrease in water treatment efficiency. Therefore, an environmentally friendly water treatment aeration device is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an environmentally friendly water treatment aeration device to address the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an environmentally friendly water treatment aeration device, comprising a treatment tank, a rotating shaft rotatably connected to the inner wall of the treatment tank, an air pipe 1 fixedly connected to the inner wall of the rotating shaft 1, an air pipe 2 fixedly connected to the inner wall of the air pipe 1, an air pipe 3 fixedly connected to the circumferential surface of the air pipe 2, a gear 1 rotatably connected to the circumferential surface of the air pipe 2, blades fixedly connected to the circumferential surface of the rotating shaft 1, an aerator fixedly connected to the top of the rotating shaft 1, a support shaft fixedly connected to the circumferential surface of the rotating shaft 1, a reciprocating screw rotatably connected to the circumferential surface of the support shaft, a movable block movably connected to the circumferential surface of the reciprocating screw, a temperature regulating rod fixedly connected to the bottom of the movable block, a gear 2 fixedly connected to the circumferential surface of the reciprocating screw, a rack fixedly connected to the inner wall of the treatment tank, a limit rod fixedly connected to the circumferential surface of the rotating shaft 1, an anti-foaming device provided on the inner wall of the rotating shaft 1, a water pipe fixedly connected to the inner wall of the treatment tank, a water pump fixedly connected to the circumferential surface of the water pipe, and a fixed... The system includes a storage tank with a filter installed on its inner wall. A waste bin is fixedly connected to the circumference of the storage tank. The output end of the aerator is fixedly connected to air pipe one. The circumference of air pipe one is fixedly connected to air pipe two. An exhaust port is provided on the circumference of air pipe three. The aerator discharges gas through air pipe one, air pipe two, and air pipe three, exiting through the exhaust port on the circumference of air pipe three. The circumference of gear one meshes with a rack, the circumference of gear two meshes with a rack, and the circumference of the limiting rod meshes with a temperature control. The motor drives the main shaft to rotate, which in turn drives the blades to rotate, stirring the wastewater and increasing the contact area between oxygen and wastewater. The main shaft then drives the second air pipe to rotate, which in turn drives the third air pipe to rotate, aerating the wastewater and effectively improving the oxygen distribution range. The rotating shaft drives the support shaft to rotate, which in turn drives the second gear to rotate. The second gear drives the reciprocating screw to rotate, which in turn drives the movable block to move back and forth. The movable block then drives the temperature control rod to move back and forth, allowing for comprehensive heating of the wastewater.

[0007] Preferably, the defoaming device includes a defoaming box, an airbag fixedly connected to the rear of the defoaming box, a push plate slidably connected to the inner wall of the defoaming box, push blocks fixedly connected to the left and right sides of the push plate, and a sleeve block slidably connected to the surface of the push plate. The defoaming device also includes a support base, a support rod fixedly connected to the inner wall of the support base, a connecting rod rotatably connected to the circumferential surface of the support rod, an inclined block fixedly connected to the top of the connecting rod, a small water ladle fixedly connected to the front of the connecting rod, the bottom of the defoaming box fixedly connected to the support base, the bottom of the sleeve block fixedly connected to the movable block, and the inner wall of the defoaming box slidably connected to an air tube. The airbag drives the defoaming box to rise, which can... The system keeps the scum removal box constantly on the surface of the wastewater to treat the scum. The rotating shaft drives the scum removal box to rotate and scrape off the scum from the wastewater surface. The movable block drives the sleeve block to move back and forth, which in turn drives the push plate to move back and forth, squeezing and defoaming the scum inside the scum removal box, further increasing the efficiency of scum removal. The push plate drives the push block to move back and forth, and the contact between the push block and the inclined surface of the inclined block pushes the inclined block to move downward. The inclined block drives the connecting rod to move downward, and the connecting rod rotates due to the limit of the support seat and support rod, which drives the small water ladle to move upward and splash water onto the scum removal box. This can clean the scum removal box and prevent impurities in the scum from accumulating inside the scum removal box, which could cause the push plate to jam.

[0008] Preferably, the filtration device includes a second rotating shaft, a filter screen fixedly connected to the circumferential surface of the second rotating shaft, a conveyor belt drivingly connected to the circumferential surface of the second rotating shaft, a small rotating shaft drivingly connected to the end of the conveyor belt away from the second rotating shaft, a protrusion fixedly connected to the bottom of the filter screen, a support block fixedly connected to the inner wall of the storage tank, a striking rod slidably connected to the inner wall of the support block, a support plate fixedly connected to the circumferential surface of the striking rod, a spring provided between the support block and the support plate, and the circumferential surface of the small rotating shaft rotatably connected to the storage tank. The inner wall of the storage tank is rotatably connected to the filter screen. The second rotating shaft drives the filter screen to rotate, and the filter screen will carry impurities to the conveyor belt. The second rotating shaft drives the conveyor belt to transport the impurities on the filter screen into the waste bin. This can prevent impurities from accumulating on the filter screen, which would lead to a decrease in filtration efficiency or clogging of the filter screen. The filter screen drives the protrusion to rotate. The arc surface of the protrusion contacts the striking rod and presses the striking rod down. After the protrusion moves away, the striking rod will move upward due to the spring force and strike the filter screen, which can shake off the impurities attached to the filter screen and prevent the filter screen from clogging.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This environmentally friendly water treatment aeration device utilizes the coordinated action of a treatment tank, aerator, rotating shaft one, air pipe one, air pipe two, air pipe three, gear one, rack, reciprocating screw, gear two, movable block, limit rod, temperature regulating rod, and blades. Rotating shaft one drives air pipe three and blades to rotate, stirring the water in the treatment tank and injecting oxygen, effectively improving the oxygen distribution range and increasing the contact area between oxygen and wastewater. In cold weather, the temperature regulating rod heats the wastewater, and the movable block drives the temperature regulating rod to move back and forth, allowing for comprehensive heating of the wastewater. This prevents the water viscosity from increasing due to low temperatures, which would increase the resistance to oxygen diffusion from air bubbles into the water, thus significantly reducing aeration efficiency. Furthermore, the activity of aerobic bacteria decreases in low-temperature environments, leading to a decline in wastewater treatment efficiency.

[0010] 2. This environmentally friendly water treatment aeration device, through the coordinated action of a rotating shaft, rack, reciprocating screw, gear 2, movable block, skimmer box, air bladder, sleeve block, push plate, push block, inclined block, connecting rod, small water ladle, support base, and support rod, allows the air bladder to move the skimmer box up and down according to the water level, ensuring the skimmer box remains on the wastewater surface to treat the foam. The rotating shaft drives the skimmer box to rotate, scraping away the foam on the wastewater surface and preventing the foam from forming a physical barrier that isolates air from the water, thus reducing oxygenation efficiency and consequently wastewater treatment efficiency. The movable block drives the push plate to move reciprocally, squeezing the foam inside the skimmer box and further improving the foam removal efficiency. The contact between the push block and the inclined block presses the inclined block down, causing the small water ladle to swing upward, splashing water onto the skimmer box to clean it and prevent impurities in the foam from accumulating inside, which could cause the push plate to jam.

[0011] 3. This environmentally friendly water treatment aeration device utilizes the coordinated action of a storage tank, rotating shaft two, filter screen, transmission belt, small rotating shaft, protrusion, striking rod, support plate, support block, and waste bin. Rotating shaft two drives the transmission belt to transport impurities on the filter screen into the waste bin, preventing impurities from accumulating on the filter screen and thus reducing filtration efficiency or causing the filter screen to become clogged. The arc surface of the protrusion contacts the striking rod, pressing the striking rod down. When the protrusion separates from the striking rod, the striking rod moves upward through spring force to strike the filter screen, vibrating the impurities attached to the filter screen and preventing clogging.

The circumferential surface of the air pipe 4 is fixedly connected to the air pipe 5. An exhaust hole is provided on the circumferential surface of the air pipe 6. The aerator 2 pumps gas... After passing through air pipe 1 (4), air pipe 2 (5), and air pipe 3 (6), the wastewater is discharged from the exhaust hole on the circumferential surface of air pipe 3 (6). The circumferential surface of gear 1 (7) meshes with rack 8, and the circumferential surface of gear 2 (10) meshes with rack 8. The circumferential surface of limit rod 12 is slidably connected to temperature regulating rod 13. Movable block 11 drives temperature regulating rod 13 to move back and forth, which can heat the wastewater in all directions, preventing the water viscosity from increasing due to low temperature, and the resistance to oxygen diffusion from bubbles to water, which would lead to a significant decrease in aeration efficiency. Aerobic bacteria will also have reduced activity due to low temperature, which would lead to a decrease in wastewater treatment efficiency. The defoaming device 14 includes a foam scraper box 1401, with an airbag 1402 fixedly connected to the rear of the foam scraper box 1401. A push plate 1404 is slidably connected to the inner wall of the foam scraper box 1401. The push plate 1404 is positioned on the left and right sides. Push blocks 1405 are fixedly connected to both sides, and sleeve blocks 1403 are slidably connected to the surface of push plate 1404. Rotating shaft 13 drives the scum scraper box 1401 to rotate, scraping off the foam on the surface of the sewage to prevent the foam from forming a physical barrier on the water surface, thus isolating air from contacting the water and reducing oxygenation efficiency, thereby reducing sewage treatment efficiency. Movable block 11 drives push plate 1404 to move back and forth, and push plate 1404 will squeeze the foam in scum scraper box 1401, further improving the foam removal efficiency. The defoaming device 14 also includes a support base 1409, with a support rod 1410 fixedly connected to the inner wall of support base 1409. A connecting rod 1407 is rotatably connected to the circumference of support rod 1410, and an inclined block 1406 is fixedly connected to the top of connecting rod 1407.A small water ladle 1408 is fixedly connected to the front of the connecting rod 1407.

The inner wall of the skimmer box 1401 is slidably connected to the air pipe 4. When the inclined block 1406 moves downward, it will cause the small water ladle 1408 to swing upward, splashing water onto the skimmer box 1401. This cleans the skimmer box 1401 and prevents impurities in the scum from accumulating inside, which could cause the push plate 1404 to jam.

[0016] Working Principle: A motor is installed at the bottom of treatment tank 1, and the output end of the motor is fixedly connected to the rotating shaft 3. Wastewater is added to the device through the top of treatment tank 1. When the motor is started, the motor drives the rotating shaft 3 to rotate, which in turn drives the blades 20 to rotate, stirring the wastewater and increasing the contact area between oxygen and wastewater. The main shaft drives the second air pipe 5 to rotate, which in turn drives the third air pipe 6 to rotate, aerating the wastewater and effectively improving the oxygen distribution range. The rotating shaft 3 drives the support shaft 21 to rotate, which in turn drives the gear 10 to rotate, which in turn drives the reciprocating screw 9 to rotate. The reciprocating screw 9 drives the movable block 11 to move back and forth, which in turn drives the temperature regulating rod 13 to move back and forth, allowing for all-round heating of the wastewater. When the water level rises, buoyancy will cause the air bag 1402 to rise, which in turn drives the skimmer box 1401 to rise, ensuring that the skimmer box 1401 remains constantly heated. The system treats scum on the surface of sewage. The rotating shaft 3 drives the scum scraper box 1401 to rotate and scrape off the scum on the sewage surface. The movable block 11 drives the sleeve block 1403 to move back and forth. The sleeve block 1403 drives the push plate 1404 to move back and forth and squeeze and defoam the scum in the scum scraper box 1401, further increasing the efficiency of scum treatment. The push plate 1404 drives the push block 1405 to move back and forth. The push block 1405 contacts the inclined surface of the inclined block 1406 and pushes the inclined block 1406 to move downward. The inclined block 1406 drives the connecting rod 1407 to move downward. The connecting rod 1407 rotates due to the limit of the support seat 1409 and the support rod 1410, and drives the small water ladle 1408 to move upward and splash water onto the scum scraper box 1401. This can clean the scum scraper box 1401 and prevent impurities in the scum from accumulating in the scum scraper box 1401, which would cause the push plate 1404 to jam.

[0017] Please see Figures 1-6Based on the above embodiments, in another embodiment of the present invention, the filtration device 17 includes a second rotating shaft 1701, a filter screen 1702 fixedly connected to the circumferential surface of the second rotating shaft 1701, a conveyor belt 1703 drivingly connected to the circumferential surface of the second rotating shaft 1701, and a small rotating shaft 1704 drivingly connected to one end of the conveyor belt 1703 away from the second rotating shaft 1701. The second rotating shaft 1701 drives the conveyor belt 1703 to transport impurities on the filter screen 1702 into the waste bin 19, which can prevent impurities from accumulating on the filter screen 1702, thereby reducing the filtration efficiency or clogging the filter screen 1702. A protrusion 1705 is fixedly connected to the bottom, and the inner wall of the storage tank 18 is fixedly connected to... A support block 1708 is attached, and a striking rod 1706 is slidably connected to the inner wall of the support block 1708. A support plate 1707 is fixedly connected to the circumferential surface of the striking rod 1706. A spring is provided between the support block 1708 and the support plate 1707. The circumferential surface of the small rotating shaft 1704 is rotatably connected to the storage tank 18. The inner wall of the storage tank 18 is rotatably connected to the filter screen 1702. When the arc surface of the protrusion 1705 contacts the striking rod 1706, it will press the striking rod 1706 down. When the protrusion 1705 separates from the striking rod 1706, the striking rod 1706 will move upward by the spring force to strike the filter screen 1702, which can shake off the impurities attached to the filter screen 1702 and prevent the filter screen 1702 from clogging.

[0018] Working principle: The water pump 15 is started to draw water and impurities into the storage tank 18 through the water pipe 16. A motor is installed at the bottom of the storage tank 18, and the output end of the motor is fixedly connected to the rotating shaft 1701. When the motor is started, the rotating shaft 1701 drives the filter screen 1702 to rotate. The filter screen 1702 will carry the impurities to the conveyor belt 1703. The rotating shaft 1701 drives the conveyor belt 1703 to drive the transmission, and the conveyor belt 1703 will transport the impurities on the filter screen 1702 into the waste bin 19. This prevents impurities from accumulating on the filter screen 1702, which could reduce filtration efficiency or cause the filter screen 1702 to become clogged. The filter screen 1702 drives the protrusion 1705 to rotate. When the arc surface of the protrusion 1705 contacts the striking rod 1706, it will press the striking rod 1706 down. After the protrusion 1705 moves away, the striking rod 1706 will move upward due to the spring force and strike the filter screen 1702. This can shake off the impurities attached to the filter screen 1702 and prevent the filter screen 1702 from becoming clogged.
