Description

Technical Field

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

[0002] Environmentally friendly wastewater aeration is a treatment method that introduces air or oxygen into wastewater to promote the decomposition of organic matter and remove pollutants. This technology is widely used in wastewater treatment plants and industrial wastewater treatment, aiming to improve the self-purification capacity of water bodies and reduce environmental pollution. Environmentally friendly wastewater aeration systems primarily rely on gas diffusion and water agitation to increase the dissolved oxygen content in the water, thereby providing the necessary oxygen for microbial growth and promoting the degradation of organic matter and the removal of pollutants such as nitrogen and phosphorus. Compared to traditional aeration methods, environmentally friendly wastewater aeration systems have higher energy efficiency and lower operating costs.

[0003] The utility model authorized by announcement number CN220951397U discloses an environmentally friendly sewage aeration device. This utility model, through the arrangement of a cavity disc, a first servo motor, a disc, a positioning slider, a round rod, a connecting rod, an adjusting plate, an aerator, and an aeration pipe, enables the environmentally friendly sewage aeration device to increase the aeration range. The gears, racks, scales, and other related mechanisms allow for a direct observation of the aeration position of the aeration particles descending into the sewage.

[0004] The above-mentioned device can adjust the height and range of sewage aeration. However, the aeration pipe in the device is exposed. When the adjustment plate 8 is rotated in both directions, the aeration pipe shakes back and forth. After the device has been working for a long time, cracks are likely to appear at the connection of the aeration pipe, which is not conducive to the device's long-term aeration treatment of sewage. Therefore, a new type of environmentally friendly sewage aeration device is needed. Utility Model Content

[0005] The purpose of this invention is to provide an environmentally friendly wastewater aeration device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An environmentally friendly wastewater aeration device includes a support plate, a sealed housing located below the support plate, limit rods fixedly mounted on the front and rear sides of the upper end of the sealed housing and slidably connected to the support plate, and an electric push rod fixedly mounted between the support plate and the sealed housing. A sliding tube is fixedly mounted on one side of the electric push rod on the sealed housing. An aerator is fixedly mounted above the support plate on one side of the limit rod, and an upper sliding tube is fixedly mounted on one side of the electric push rod below the support plate and slidably connected to the sliding tube. The upper end of the upper sliding tube is connected to the outlet of the aerator. The air inlet is connected, and a reduction motor is fixedly installed on one side of the sliding tube above the sealed box. A hollow rotating rod is installed between the two limiting rods and passes through the top and bottom plates of the sealed box. A sealed bearing is installed at the connection between the hollow rotating rod and the top and bottom plates of the sealed box. The output shaft of the reduction motor is connected to the hollow rotating rod through a bevel gear transmission mechanism. Several vent holes are evenly opened on the hollow rotating rod inside the sealed box. Several agitating fan blades are fixedly installed on the hollow rotating rod below the sealed box. Several air outlet holes are evenly opened on the agitating fan blades.

[0008] As a further embodiment of this utility model: several sliding rods are evenly slidably arranged at both ends of the support plate, and a movable plate is fixedly arranged at the outer end of the sliding rod.

[0009] As a further improvement of this utility model, a second sealing ring is embedded in the upper end of the sliding tube.

[0010] As a further improvement of this utility model, a first sealing ring is embedded in the lower end of the upper sliding tube.

[0011] As a further improvement of this utility model, a guide cone is fixedly provided at the lower end of the hollow rotating rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. By using the movable plate and sliding rod together, the length of the support plate can be extended, making it easy to fix the support plate above the aeration tank or aeration box. The electric push rod can control the vertical displacement of the sealing box. The limiting rod plays a limiting role when the sealing box is displaced. At the same time, when the sealing box is displaced, the upper sliding pipe and the lower sliding pipe move relative to each other, which makes it easy for the aerator to transfer air into the sealing box, facilitating subsequent aeration treatment of sewage by relevant agencies.

[0014] 2. The hollow rotating rod is driven by a geared motor as a power source. Multiple agitator blades at different heights rotate to stir the sewage, which facilitates the aerator to send air into the sewage. On the one hand, it allows the air to fully contact the sewage, enabling aerobic bacteria to treat the sewage. On the other hand, it helps to lift up the sludge at the bottom of the pool, preventing the sludge from accumulating at the bottom and thus preventing the aerator from being unable to fully aerate the sewage. This increases the aeration range of the device and improves the aeration effect. Attached Figure Description

[0020] Example

[0021] Please see Figures 1-3In this embodiment of the present invention, an environmentally friendly wastewater aeration device includes a support plate 1. Several sliding rods 3 are evenly slidably arranged at both ends of the support plate 1. A movable plate 2 is fixedly installed at the outer end of each sliding rod 3. A sealed box 5 is arranged below the support plate 1. Limiting rods 4 are fixedly installed on the front and rear sides of the upper end of the sealed box 5, and the limiting rods 4 pass through the support plate 1 and are slidably connected to the support plate 1. An electric push rod 9 is fixedly arranged between the support plate 1 and the sealed box 5. A sliding tube 7 is fixedly installed on one side of the electric push rod 9 on the sealed box 5. A second sealing ring 17 is embedded in the upper end of the sliding tube 7. An aerator 6 is fixedly arranged above the support plate 1 on one side of the limiting rod 4. The electric push rod 9 is fixedly installed on one side below the support plate 1 with an upper sliding tube 8 and a lower sliding tube 7 slidably connected. The upper end of the upper sliding tube 8 is connected to the air outlet of the aerator 6, and the lower end of the upper sliding tube 8 is fitted with a first sealing ring 16. By cooperating with the moving plate 2 and the sliding rod 3, the length of the support plate 1 can be extended, making it easier to fix the support plate 1 above the aeration tank or aeration box. The electric push rod 9 can control the vertical displacement of the sealing box 5. The limiting rod 4 plays a limiting role when the sealing box 5 is displaced. At the same time, when the sealing box 5 is displaced, the upper sliding tube 8 and the lower sliding tube 7 move relative to each other, which makes it easier for the aerator 6 to transfer air into the sealing box 5, facilitating subsequent aeration treatment of sewage by relevant agencies.

[0022] A reduction motor 10 is fixedly installed on one side of the sliding tube 7 above the sealed housing 5. A hollow rotating rod 12 is arranged between the two limiting rods 4, and the hollow rotating rod 12 passes through the top and bottom plates of the sealed housing 5. A sealed bearing 18 is provided at the connection between the hollow rotating rod 12 and the top and bottom plates of the sealed housing 5. The output shaft of the reduction motor 10 is connected to the hollow rotating rod 12 through a bevel gear transmission mechanism 11. Several ventilation holes 13 are evenly opened on the hollow rotating rod 12 inside the sealed housing 5. Several agitator blades 14 are fixedly installed on the hollow rotating rod 12 below the sealed housing 5. The stirring fan blades 14 are evenly provided with several air outlets. The lower end of the hollow rotating rod 12 is fixedly provided with a guide cone 15. The hollow rotating rod 12 is driven to rotate by the reduction motor 10 as a power source. The multiple stirring fan blades 14 at different heights rotate to stir the sewage, which makes it easier for the aerator 6 to send air into the sewage. On the one hand, it is easy for the air to come into full contact with the sewage, so that the aerobic bacteria can treat the sewage. On the other hand, it is easy to lift the sludge at the bottom of the pool, so as to avoid the sludge from accumulating at the bottom of the pool and preventing the aerator 6 from being unable to fully aerate the sewage. This increases the aeration range of the device and improves the aeration effect of the device.

[0023] When using the device, the movable plate 2 and the sliding rod 3 are pulled out from the support plate 1, and the entire device is placed above the aeration tank or aeration box. The aerator 6 and the reduction motor 10 are started. The aerator 6 aerates air into the sealed box 5, and the air is fed to the stirring blade 14 through the air vent 13 on the hollow rotating rod 12. The reduction motor 10 drives the hollow rotating rod 12 and the stirring blade 14 to rotate through the bevel gear transmission mechanism 11, thereby aerating the sewage. When the height of the stirring blade 14 needs to be adjusted, the electric push rod 9 is started. With the cooperation of the limit rod 4, the height of the sealed box 5, the hollow rotating rod 12 and the stirring blade 14 are adjusted to further expand the aeration range of the device.
