Description

Technical Field

[0001] This utility model relates to the field of water aeration technology, specifically to an integrated air-water mixing oxygenation system. Background Technology

[0002] Maintaining sufficient dissolved oxygen levels in water bodies is crucial in aquaculture, landscape water treatment, and industrial wastewater management. It not only affects the healthy growth of aquatic organisms but also influences the balance of the aquatic ecosystem and the degradation efficiency of pollutants. Traditional oxygenation methods include mechanical agitation, surface aeration, and diffusion aeration, but these generally suffer from limited dissolved oxygen efficiency, high energy consumption, small coverage area, or significant noise pollution.

[0003] Existing aeration equipment is difficult to adapt flexibly to the aeration needs of ponds of different sizes and is difficult to manage centrally. In addition, the noise and vibration generated by the equipment during aeration can easily disturb farmed fish and affect their normal growth, so improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide an integrated air-water mixing aeration system to address the above problems, thereby solving the issues of difficulty in centralized management of aeration equipment and the disturbance of fish schools by aeration noise in the existing technology.

[0005] To achieve the above objectives, this utility model discloses an integrated air-water mixing oxygenation system, including an oxygenation tower. The oxygenation tower is frustum-shaped and has an aeration chamber inside. It also includes a main water supply pipe for conveying water flow, and multiple oxygenation towers are provided. Multiple branch water supply pipes are connected to the main water supply pipes, which are connected to the upper pipeline of the oxygenation tower. The system also includes an aerator for supplying airflow to the oxygenation tower. The outlet of the aerator is connected to an air supply pipe, which is connected to the lower pipeline of the oxygenation tower. A water supply pipe for supplying water to a water tank is connected to the lower part of the oxygenation tower.

[0006] The number of aeration towers can be flexibly selected according to the size of the pool. A main water supply pipe and an air supply pipe provide water and air to multiple aeration towers simultaneously, achieving efficient aeration of large-area pools. The air supply pipe connects to the lower part of the aeration tower, and the branch water supply pipe connects to the upper part of the aeration tower. As the water flows down, it can better mix and contact with the rising air bubbles, prolonging the contact time between the bubbles and water and improving dissolved oxygen efficiency. This system can be placed far away from the pool, which can avoid the noise generated by aeration disturbing the fish in the pool.

[0007] An aerator is installed in the aeration chamber, located at the bottom of the oxygenation tower. An aerator pipe is connected to the aerator, passing through the oxygenation tower and connecting to the air supply pipeline. The aerator can be either a tubular or disc type. The aerator converts the air supplied by the aerator into tiny bubbles, greatly increasing the contact area between the gas and liquid phases.

[0008] The upper part of the oxygenation tower is equipped with a water injection pipe, which is connected to a branch water supply pipe at the top. The lower end of the water injection pipe extends into the aeration chamber. Water is injected from the top of the oxygenation tower, and the water flow impacts the water in the tower, generating bubbles, which helps to improve dissolved oxygen efficiency.

[0009] The lower end of the water injection pipe is connected to a water distribution bucket, which has multiple mesh openings. Inside the bucket, an impeller is rotatably mounted to disperse the water flow. The falling water impacts the impeller, driving it to rotate and thus breaking the water flow into fine streams. These fine streams then collide with the water distribution bucket, transforming into even finer droplets and water films, maximizing the contact area between the water and air and improving dissolved oxygen efficiency.

[0010] The impeller is equipped with multiple blades, which are spaced apart around the impeller. The blades are propeller blades, which drive the impeller to rotate under the impact of the water flow, thereby dispersing the water flow.

[0011] The water distribution hopper is funnel-shaped, with the smaller diameter end facing upwards and connected to the water inlet pipe, and the larger diameter end facing downwards. The water distribution hopper allows the water flow to naturally diffuse towards the larger bottom area.

[0012] A support sleeve is installed inside the water distribution hopper. The impeller is rotatably mounted on the support sleeve, which is equipped with multiple support rods arranged at intervals around the sleeve. The end of each support rod furthest from the sleeve is fixedly connected to the water distribution hopper. The support sleeve provides a stable axis of rotation for the impeller, ensuring its long-term stable operation. The spaced arrangement of the support rods reduces resistance to water flow.

[0013] The oxygenation tower consists of a tank that opens downwards, and a base that seals the opening at the bottom of the tank. The tank and the base are connected by a flange, allowing for the inspection or replacement of components inside the tank, such as aerators and water separators, by opening the base.

[0014] The oxygenation tower has an outlet pipe connected to its side, located at the bottom of the tower, which is connected to the water supply pipe. Oxygenated water is delivered from the bottom, ensuring that water with the highest dissolved oxygen content is delivered to the water tank.

[0015] An air-suspended aerator is an application of an air-suspended blower. Under the same power, an air-suspended aerator has lower energy consumption.

[0016] In summary, the beneficial effects of this utility model are as follows: This system can achieve efficient oxygenation of large-area pools. The falling water flow impacts the impeller, driving the impeller to rotate, thereby breaking the water flow into fine water flow. The fine water flow hits the water distribution bucket, converting it into even finer water droplets and water films, maximizing the contact area between water and air, and improving dissolved oxygen efficiency. This system can be placed far away from the pool, avoiding the noise generated by aeration from disturbing the fish in the pool. Attached Figure Description

The aerator 1 is preferably an air-suspended centrifugal aerator. The outlet of the aerator 1 is connected to an air supply pipe 2, which is connected to the lower pipeline of the aeration tower 3. The lower part of the aeration tower 3 is connected to a water supply pipe 5 for supplying water to a water tank 6. The water tank 6 can be a landscape water tank, an aquaculture tank, or an industrial wastewater tank. (See attached diagram) Figure 1The number of oxygenation towers 3 can be flexibly selected according to the size of the pool 6. A main water supply pipe 4 and an air supply pipe 2 provide water and air to multiple oxygenation towers 3 simultaneously, achieving efficient oxygenation of a large area of ​​pool 6. The air supply pipe 2 is connected to the lower part of the oxygenation tower 3, and the branch water supply pipe 7 is connected to the upper part of the oxygenation tower 3. The water flow can better mix and contact with the rising air bubbles during the falling process, prolonging the contact time between the bubbles and the water and improving the dissolved oxygen efficiency. This system can be placed far away from the pool 6, which can avoid the noise generated by aeration disturbing the fish raised in the pool 6.

[0022] See attached document Figure 2 An aerator 13 is installed in the aeration chamber 20, located at the bottom of the oxygenation tower 3. An aerator 13 is connected to an aerator pipe 16, which passes through the oxygenation tower 3 and connects to the air supply pipe 2. The aerator 13 can be either a tubular or disc type. The aerator 13 converts the air supplied by the aerator 1 into microbubbles, greatly increasing the contact area between the gas and liquid phases. A water injection pipe 8 is located at the top of the oxygenation tower 3, connected to a branch water supply pipe 7 at its upper part. The lower end of the water injection pipe 8 extends into the aeration chamber 20. Water is injected from the top of the oxygenation tower 3, and the water flow impacts the water in the oxygenation tower 3, generating bubbles, which helps improve dissolved oxygen efficiency.

[0023] See attached document Figure 3 The lower end of the water injection pipe 8 is connected to a water distribution hopper 9, which has multiple mesh openings 12. An impeller 10 for dispersing the water flow is rotatably installed in the water distribution hopper 9. The falling water flow impacts the impeller 10, driving it to rotate, thereby dispersing the water flow into fine streams. These fine streams then collide with the water distribution hopper 9, transforming into even finer water droplets and water films, maximizing the contact area between water and air and improving dissolved oxygen efficiency. (See attached diagram) Figure 4 The impeller 10 is equipped with multiple blades 11, which are spaced apart around the impeller 10. The blades 11 are propeller blades, which drive the impeller 10 to rotate under the impact of the water flow, thus dispersing the water flow. The water distribution bucket 9 is funnel-shaped, with the smaller diameter end facing upwards and connected to the water inlet pipe 8, and the larger diameter end facing downwards. The water distribution bucket 9 allows the water flow to naturally diffuse towards the larger bottom area. (See attached diagram.) Figure 3 A support sleeve 18 is installed in the water distribution hopper 9. The impeller 10 is rotatably mounted on the support sleeve 18. Multiple support rods 17 are installed on the support sleeve 18, arranged at intervals around the support sleeve 18. The end of the support rod 17 away from the support sleeve 18 is fixedly connected to the water distribution hopper 9. The support sleeve 18 provides a stable axis of rotation for the impeller 10, ensuring its long-term stable operation. The spaced arrangement of the support rods 17 can reduce resistance to water flow.

A base 14, which closes the opening at the bottom of the tank 15, is connected to the lower part of the tank 15. The tank 15 and the base 14 are connected by a flange. By opening the base 14, components inside the tank 15, such as the aerator 13 and the water distributor 9, can be inspected or replaced.
