Description

Technical Field

[0001] This utility model relates to the field of aerator technology, and more specifically, to an aerator for water pollution treatment. Background Technology

[0002] Aeration technology is a key component of water treatment systems, playing an irreplaceable role, especially in wastewater treatment. As the core component of aeration technology, aerators can effectively increase the dissolved oxygen content in water, which is crucial for promoting the degradation of organic matter and the removal of nutrients such as nitrogen and phosphorus in wastewater. At the same time, aeration also has the function of mixing and stirring, which helps to improve the effect and efficiency of wastewater treatment. The working principle of aerators is mainly to introduce air bubbles into the water to achieve the exchange of substances between gas and liquid.

[0003] There are many types of aerators currently available. Among them, disc aerators are installed near the bottom of the sewage tank, and bubbles are generated from the top of the aeration disc. During the use of the aeration disc, an appropriate number of bubbles and a suitable bubble size help to increase the contact area and time between oxygen and sewage, thereby improving the oxygen dissolution efficiency. However, current aerators are difficult to control the number of bubbles generated, making it impossible to adjust the number of bubbles generated according to the actual situation and avoid energy waste caused by over-aeration. Utility Model Content

[0004] This invention addresses the problem in the prior art that current aerators struggle to control the number of bubbles produced, and proposes an aerator for water pollution treatment.

[0006] A connecting cylinder is located in the middle section of the connecting pipe, and an air intake control component is installed inside the connecting cylinder to control the air intake of the aeration disc.

[0007] The cleaning component is installed on the connecting cylinder and the aeration disc. The cleaning component is used to clean the top of the aeration disc.

[0008] Furthermore, the air intake control component includes a fixed ring plate fixed to the inner wall of the connecting cylinder, a plurality of movable columns are slidably inserted in the fixed ring plate, one end of each movable column is fixed to a cylinder, a connecting strip is fixed between two adjacent cylinders, and a connecting membrane is fixed between the plurality of cylinders and the bottom inner wall of the connecting cylinder, and both the connecting membrane and the connecting strip are elastic.

[0009] Furthermore, a fixing block is fixedly connected to the top of the movable column, a lifting ring plate is slidably connected to the inner wall of the connecting cylinder, a connecting rod is hinged between the lifting ring plate and multiple fixing blocks, a connecting plate is fixedly connected to the lifting ring plate and slidably connected to the side wall of the connecting cylinder, an electric push rod is fixedly connected to the outer wall of the connecting cylinder, and the output end of the electric push rod is fixedly connected to the bottom of the connecting plate.

[0010] Furthermore, two baffles are fixedly connected to the connecting plate, and two slots are opened on the side wall of the connecting cylinder, with the two baffles respectively inserted into the corresponding slots.

[0011] Furthermore, the cleaning assembly includes a scraper rod disposed on top of the aeration disc, with L-shaped rods fixedly connected to both ends of the scraper rod, and a rotating ring fixedly connected to one end of each of the two L-shaped rods, the rotating ring being rotatably connected to the outer wall of the connecting cylinder.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 6 An aerator for water pollution treatment includes an aeration disc 1 and a connecting pipe 2 disposed at the bottom of the aeration disc 1. The outer wall of the bottom end of the connecting pipe 2 is provided with external threads. The aerator also includes:

[0026] Connecting cylinder 3 is located in the middle section of connecting pipe 2, and an air intake control component for controlling the air intake of aeration disc 1 is installed inside connecting cylinder 3.

[0027] A cleaning component is installed on the connecting cylinder 3 and the aeration disc 1. The cleaning component is used to clean the top of the aeration disc 1.

[0028] During use, air enters the aeration disc 1 through the connecting pipe 2 and connecting cylinder 3. The aeration disc 1 converts the air into bubbles and delivers them to the wastewater. When it is necessary to adjust the number of bubbles produced by the aeration device, the amount of air entering the aeration disc 1 per unit time can be controlled by the air intake control component, thereby controlling the number of bubbles produced by the aeration disc 1. During the air passing through the connecting cylinder 3, the cleaning component can clean the top of the aeration disc 1, scraping away the sludge and impurities on the top of the aeration disc 1.

[0029] Reference Figure 3 , Figure 4 and Figure 5 The air intake control component includes a fixed ring plate 4 fixed to the inner wall of the connecting cylinder 3. Multiple movable columns 5 are slidably inserted into the fixed ring plate 4. A cylinder 6 is fixed to one end of each movable column 5. A connecting strip 7 is fixed between adjacent cylinders 6. A connecting membrane 25 is fixed between the multiple cylinders 6 and the bottom inner wall of the connecting cylinder 3. Both the connecting membrane 25 and the connecting strip 7 are elastic. When it is necessary to adjust the number of bubbles generated by the aerator, the multiple cylinders 6 and the connecting strip 7 form a closed circle. When air passes through the connecting cylinder 3, it passes through the closed circle, causing the multiple cylinders 6 to move simultaneously towards or away from the center of the closed circle. The cylinders 6 drive the connecting strip 7 to move, and the connecting strip 7 is stretched or contracted, thereby changing the diameter of the closed circle. By changing the diameter of the closed circle, the amount of air passing through the closed circle per unit time can be adjusted, thus achieving the adjustment of the number of bubbles generated by the aerator.

[0030] Reference Figure 2 , Figure 4 and Figure 5 A fixed block 8 is fixedly connected to the top of the movable column 5. A lifting ring plate 10 is slidably connected to the inner wall of the connecting cylinder 3. A connecting rod 9 is hinged between the lifting ring plate 10 and multiple fixed blocks 8. A connecting plate 11 is fixedly connected to the lifting ring plate 10 and slidably connected to the side wall of the connecting cylinder 3. An electric push rod 12 is fixedly connected to the outer wall of the connecting cylinder 3. The output end of the electric push rod 12 is fixedly connected to the bottom of the connecting plate 11. When it is necessary to control the amount of air entering the aeration disc 1, the electric push rod 12 is activated. The electric push rod 12 drives the connecting plate 11 to move in the vertical direction. The connecting plate 11 drives the lifting ring plate 10 to move. The lifting ring plate 10 drives the fixed blocks 8 to move through multiple connecting rods 9. Multiple fixed blocks 8 can drive multiple movable columns 5 and cylinders 6 to move, so that multiple cylinders 6 move simultaneously toward or away from the closed circle center, thereby achieving the purpose of adjusting the diameter of the closed circle.

[0031] Reference Figure 4Two baffles 13 are fixedly connected to the connecting plate 11, and two slots 14 are opened on the side wall of the connecting cylinder 3. The two baffles 13 are respectively inserted into the corresponding slots 14. When the electric push rod 12 drives the connecting plate 11 to move in the vertical direction, the connecting plate 11 drives the baffles 13 to move, so that the baffles 13 move in the slots 14. The baffles 13 can keep the connecting cylinder 3 sealed and prevent sewage from entering the connecting cylinder 3.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 The cleaning assembly includes a scraper 15 disposed on the top of the aeration disc 1. Both ends of the scraper 15 are fixedly connected to L-shaped rods 16. One end of each L-shaped rod 16 is fixedly connected to a rotating ring 17, which is rotatably connected to the outer wall of the connecting cylinder 3. When it is necessary to clean the sludge and impurities on the top of the aeration disc 1, the rotating ring 17 rotates on the outer wall of the connecting cylinder 3. The rotating ring 17 drives the scraper 15 to rotate through the L-shaped rods 16, and the scraper 15 can scrape off the sludge and impurities.

[0033] Reference Figure 3 and Figure 6 The inner wall of the connecting cylinder 3 is fixedly connected to a bracket 18. A first rotating shaft 19 is rotatably connected to the middle of the bracket 18. Multiple fan blades 20 are fixedly connected to the outer wall of the first rotating shaft 19. A second rotating shaft 21 is rotatably connected to the side wall of the connecting cylinder 3. A first bevel gear 22 that meshes with each other is fixedly connected to one end of the second rotating shaft 21 and the top end of the first rotating shaft 19. A second bevel gear 23 is fixedly connected to the other end of the second rotating shaft 21. A bevel ring 24 that meshes with the second bevel gear 23 is fixedly connected to the top of the rotating ring 17. As air passes through the connecting cylinder 3, the air blows the fan blades 20 to rotate. The fan blades 20 drive the first rotating shaft 19 to rotate. The first rotating shaft 19 drives the second rotating shaft 21 to rotate through the two first bevel gears 22. The second rotating shaft 21 drives the rotating ring 17 to rotate through the second bevel gear 23 and the bevel ring 24, thereby causing the scraper 15 to clean the top of the aeration disc 1.

[0034] Working principle: During use, air enters the aeration disc 1 through the connecting pipe 2 and connecting cylinder 3. The aeration disc 1 converts the air into bubbles and delivers them to the sewage. When it is necessary to adjust the number of bubbles produced by the aeration device, the amount of air entering the aeration disc 1 per unit time can be controlled by the air intake control component, thereby controlling the number of bubbles produced by the aeration disc 1. During the air passing through the connecting cylinder 3, the cleaning component can clean the top of the aeration disc 1, scraping away the sludge and impurities on the top of the aeration disc 1.

[0035] When it is necessary to adjust the number of bubbles produced by the aerator, multiple cylinders 6 and connecting belt 7 form a closed circle. When air passes through the connecting cylinder 3, it will pass through the closed circle, causing multiple cylinders 6 to move towards or away from the center of the closed circle at the same time. The cylinders 6 drive the connecting belt 7 to move, and the connecting belt 7 is stretched or contracted, thereby changing the diameter of the closed circle. By changing the diameter of the closed circle, the amount of air passing through the closed circle per unit time can be adjusted, thereby adjusting the number of bubbles produced by the aerator.

[0036] When it is necessary to control the amount of air entering the aeration disc 1, the electric push rod 12 is activated. The electric push rod 12 drives the connecting plate 11 to move in the vertical direction. The connecting plate 11 drives the lifting ring plate 10 to move. The lifting ring plate 10 drives the fixed block 8 to move through multiple connecting rods 9. The multiple fixed blocks 8 can drive multiple moving columns 5 and cylinders 6 to move, so that multiple cylinders 6 move towards or away from the closed circle center at the same time, thereby achieving the purpose of adjusting the diameter of the closed circle.

[0037] During the process of the electric push rod 12 driving the connecting plate 11 to move in the vertical direction, the connecting plate 11 drives the baffle 13 to move, so that the baffle 13 moves in the slot 14. The baffle 13 can keep the connecting cylinder 3 sealed and prevent sewage from entering the connecting cylinder 3.

[0038] When it is necessary to clean the sludge and impurities at the top of the aeration disc 1, the rotating ring 17 rotates on the outer wall of the connecting cylinder 3. The rotating ring 17 drives the scraper 15 to rotate through the L-shaped rod 16, and the scraper 15 can scrape off the sludge and impurities.

[0039] As air passes through the connecting cylinder 3, it blows the fan blades 20 to rotate. The fan blades 20 drive the first rotating shaft 19 to rotate. The first rotating shaft 19 drives the second rotating shaft 21 to rotate through two first bevel gears 22. The second rotating shaft 21 drives the rotating ring 17 to rotate through the second bevel gear 23 and the bevel gear ring 24, thereby causing the scraper 15 to clean the top of the aeration disc 1.
