Description

Technical Field

[0001] This invention relates to the field of water oxygenation and flow generation equipment, and more specifically, to an oxygenation and flow generation device. Background Technology

[0002] In the fields of aquaculture and water management, oxygenation and flow generation are core means to improve the aquatic environment. Traditional oxygenation equipment, such as impeller aerators and waterwheel aerators, mostly use surface oxygenation methods, which have limited oxygenation depth and cannot meet the needs of deep-water aquaculture. While single micro-nano bubble aerators can achieve deep-water oxygenation, they lack directional flow generation capabilities and are unable to drive overall water circulation, resulting in localized areas of oxygen enrichment and localized areas of oxygen deficiency.

[0003] Furthermore, existing technologies often suffer from drawbacks such as fragmented structures, low gas-liquid mixing efficiency, and inaccurate air intake control in some integrated aeration and flow generation devices. For example, the flow direction in some devices is uncontrollable, failing to create a stable water circulation pattern and resulting in poor water activation. Therefore, developing an aeration and flow generation device with high integration, deep aeration depth, stable flow generation effect, and precisely controllable air intake has become an urgent need in the industry.

[0004] In view of this, the present invention is proposed to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide an oxygenation and flow generation device to solve the technical problem that existing oxygenation and flow generation devices lack directional flow generation function, making it difficult to drive the overall circulation of water, resulting in local water bodies being rich in oxygen and local water bodies being deficient in oxygen.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An oxygenation and flow generation device, comprising:

[0008] The oxygenation component includes a high-pressure water flow propulsion device, the outlet of which is connected to a micro-nano bubble generator, the outlet of which is connected to a micro-nano bubble release device, and an air pipe connected to the micro-nano bubble generator, with the air inlet of the air pipe located on the water surface.

[0009] The flow-generating component includes a drive shaft, with multiple active power wheel blades evenly arranged along its circumference in the middle of the drive shaft, so that the high-pressure water flow through the micro-nano bubble releaser is sequentially sprayed onto the multiple active power wheel blades. Multiple driven power wheel blades are evenly arranged along their circumference at both ends of the drive shaft, and a flow guide shroud is fitted on the multiple driven power wheel blades at each end. The flow guide shroud is provided with an inlet and an outlet to guide the water flow to form a directional flow pattern.

[0010] The high-pressure water flow propulsion device is equipped with an inlet filter cover, which is used to filter the water entering the high-pressure water flow propulsion device. It also includes a flow restrictor set on the inlet filter cover. The micro-nano bubble generator and the micro-nano bubble releaser are located inside the flow restrictor. The two sides of the flow restrictor are fixedly connected to two flow guide covers respectively. The two ends of the drive shaft pass through the two sides of the flow restrictor respectively and are connected by bearings. The flow restrictor is used to control the flow rate and spray direction of the high-pressure water flow sprayed through the micro-nano bubble releaser.

[0011] The outlet of the micro-nano bubble releaser is a pressure-increasing inlet.

[0012] Furthermore, the high-pressure water flow propulsion device is a deep-water high-pressure multi-stage sewage pump.

[0013] Furthermore, a float is provided at the air inlet end of the air pipe to ensure that the air inlet end of the air pipe is always above the water surface.

[0014] Furthermore, an regulating valve is installed at the air inlet end of the air pipe to precisely control the air intake volume of the air pipe.

[0015] Furthermore, it also includes a lowering mechanism, which includes an installation platform set on the ground. A geared motor is installed on the installation platform, and a sleeve is connected to the output shaft of the geared motor. A traction rope is wound on the sleeve, and the other end of the traction rope is connected to the guide fairing.

[0016] Furthermore, each air deflector is equipped with at least one flexible airbag, and a miniature air pump is installed on the mounting platform. The miniature air pump is connected to the flexible airbag through a pressure-resistant air tube to inflate or deflate the flexible airbag. The miniature air pump is controlled by a controller installed on the mounting platform. A pressure sensor is installed at the bottom of the air deflector and is electrically connected to the controller.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The structure employs a combination of a micro-nano bubble generator and a micro-nano bubble releaser to achieve efficient dissolution of air and high-pressure water flow. The micro-nano bubbles have small diameters and large specific surface areas, resulting in a long residence time in the water and an oxygenation depth of 5-10m. Compared to traditional oxygenation and flow generation devices, the oxygenation efficiency is improved by more than 50%.

[0019] Driven by the main propeller blades, the secondary propeller blades rotate, generating centrifugal force that rotates the water. Combined with the backflow effect of the guide shroud, a stable directional flow is formed, which can drive the surrounding water to form an overall circulation, making the water body more evenly activated.

[0020] The float ensures that the air tube is always above the water surface to prevent water backflow, and the regulating valve can steplessly adjust the air intake to adapt to the dissolved oxygen requirements of different water bodies, making it easy to operate.

[0021] The blades are driven by high-pressure water flow, eliminating the need for an additional motor to drive the blade assembly. Compared to traditional aeration and flow generation devices, energy consumption is reduced by 30%. The core components are integrated inside the inlet filter cover, resulting in a compact structure that is easy to install and maintain. Attached Figure Description

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] See Figures 1 to 2 As shown, an oxygenation and flow generation device includes an oxygenation component and a flow generation component. The oxygenation component includes a high-pressure water flow driving device 2, with a micro-nano bubble generator 3 connected to the outlet end of the high-pressure water flow driving device 2. A micro-nano bubble release device 4 is connected to the outlet end of the micro-nano bubble generator 3. An air pipe 11 is connected to the micro-nano bubble generator 3, with the air inlet end of the air pipe 11 located on the water surface. The flow generation component includes a drive shaft 5, with multiple active power wheel blades 9 evenly arranged along its circumference in the middle of the drive shaft 5, so that the high-pressure water flow passing through the micro-nano bubble release device 4 is sequentially sprayed onto the multiple active power wheel blades 9. Multiple driven power wheel blades 8 are evenly arranged along their circumference at both ends of the drive shaft 5, and a flow guide shroud 7 is fitted on each of the multiple driven power wheel blades 8 at each end. The flow guide shroud 7 is provided with an inlet and an outlet to guide the water flow to form a directional flow pattern.

[0028] It should be noted that the micro-nano bubble generator 3 can draw in air through the air pipe 11 and fully dissolve it with the high-pressure water flow to generate micro-nano bubbles; the micro-nano bubble releaser 4 can accurately spray the high-pressure, high-speed air-containing water flow onto the main propeller blade 9 while releasing micro-nano bubbles; the flow guide shroud 7 can guide the water flow to form a directional flow pattern.

[0029] The high-pressure water flow propulsion device 2 is used to draw in water and provide power, and deliver the high-pressure water to the micro-nano bubble generator 3. At the same time, the micro-nano bubble generator 3 draws in air through the air pipe 11 and dissolves it with the high-pressure water flow. Then, the high-pressure water flow containing air is sprayed at high speed towards the main drive wheel blade 9 through the micro-nano bubble release device 4, thereby causing the main drive wheel blade 9 to rotate. The rotation of the main drive wheel blade 9 drives the driven wheel blade 8 to rotate. The rotation of the driven wheel blade 8 generates centrifugal force, which drives the water to rotate. Through the backflow effect of the guide shroud 7, a forward water flow is formed. The continuous water flow causes the surrounding water to flow together to form a flow in the same direction. The micro-nano bubbles in the gas-liquid mixed flow rise slowly in the water, continuously releasing oxygen, achieving efficient oxygenation in the deep water area, making the aquaculture water body an oxygen-rich, circulating "living water", and improving the aquaculture environment.

[0030] In the above scheme, a structure combining a micro-nano bubble generator 3 and a micro-nano bubble releaser 4 is adopted to achieve efficient dissolution of air and high-pressure water flow. The micro-nano bubbles have small diameters and large specific surface areas, resulting in a long residence time in the water and an oxygenation depth of 5-10m. Compared with traditional oxygenation and flow generation devices, the oxygenation efficiency is increased by more than 50%. The drive impeller 9 drives the driven impeller 8 to rotate, generating centrifugal force to rotate the water. Combined with the backflow effect of the guide shroud 7, a stable directional flow is formed, which can drive the surrounding water to form an overall circulation, making the water body uniformly activated.

[0031] See some possible implementations. Figure 1 and Figure 2 As shown, the high-pressure water flow propulsion device 2 is equipped with an inlet filter cover 1, which is made of stainless steel. The inlet filter cover 1 is used to filter the water entering the high-pressure water flow propulsion device 2. The high-pressure water flow propulsion device 2 is a deep-water high-pressure multi-stage sewage pump.

[0032] See some possible implementations. Figure 1 and Figure 2As shown, the oxygenation and flow generation device provided in this application embodiment also includes a flow restrictor 10 installed on the inlet filter cover 1. The micro-nano bubble generator 3 and the micro-nano bubble releaser 4 are located inside the flow restrictor 10. The two sides of the flow restrictor 10 are fixedly connected to two flow guide covers 7 respectively. The two ends of the drive shaft 5 pass through the two sides of the flow restrictor 10 respectively and are connected by bearings 6. The bearings 6 are waterproof deep groove ball bearings, and their outer sides are covered with waterproof sealing sleeves to prevent water from entering the interior of the bearings 6 and causing wear, thus ensuring the transmission stability of the drive wheel blades 9 and the driven wheel blades 8. The flow restrictor 10 is used to control the flow rate and spray direction of the high-pressure water flow sprayed through the micro-nano bubble releaser 4, and can guide the gas-liquid mixture sprayed by the micro-nano bubble releaser 4 to be discharged in a specified direction to form a complete water flow channel.

[0033] In some possible implementations, the outlet of the micro / nano bubble releaser 4 is a pressure-increasing outlet.

[0034] See some possible implementations. Figure 2 As shown, a float 13 is provided at the air inlet end of the air pipe 11. The float 13 is used to keep the air inlet end of the air pipe 11 above the water surface.

[0035] See some possible implementations. Figure 2 As shown, an regulating valve 12 is also provided at the air inlet end of the air pipe 11. The regulating valve 12 is used to precisely control the air intake of the air pipe 11.

[0036] In some possible implementations, the oxygenation and flow generation device provided in this application embodiment further includes a lowering mechanism (not shown in the figure). The lowering mechanism includes an installation platform set on the ground, a geared motor set on the installation platform, a sleeve connected to the output shaft of the geared motor, a traction rope wound on the sleeve, and the other end of the traction rope connected to the flow guide shroud 7. Each flow guide shroud 7 is provided with at least one flexible airbag, a miniature air pump is set on the installation platform, the miniature air pump is connected to the flexible airbag through a pressure-resistant air pipe to inflate or deflate the flexible airbag, the miniature air pump and the geared motor are controlled by a controller set on the installation platform, and a pressure sensor is set at the bottom of the flow guide shroud 7, the pressure sensor being electrically connected to the controller.

[0037] In the above scheme, dissolved oxygen sensors can be installed on both sides of the flow restrictor 10, and the dissolved oxygen sensors are electrically connected to the controller. When the dissolved oxygen sensor detects insufficient dissolved oxygen in the deep water area, the controller controls the geared motor to start. The geared motor drives the sleeve to rotate in the opposite direction through its output shaft, thereby driving the oxygenation and flow generation device provided in this application embodiment to be lowered as a whole through the traction rope. At the same time, the buoyancy of the flexible airbag is reduced (venting), so that the oxygenation and flow generation device is stabilized at the optimal oxygenation depth. When the surface water needs to be activated, the geared motor is controlled to start. The geared motor drives the sleeve to rotate in the forward direction through its output shaft, thereby driving the oxygenation and flow generation device provided in this application embodiment to be lifted as a whole through the traction rope. At the same time, the buoyancy of the flexible airbag is increased (inflating), achieving precise operation and greatly improving oxygenation efficiency.

[0038] Working principle

[0039] 1. In the power and bubble generation stage, the high-pressure water flow propels the device 2 to draw in water and pressurize it, delivering the high-pressure water to the micro-nano bubble generator 3. At the same time, the air pipe 11 is kept above the water surface by the float 13, and the regulating valve 12 controls the air intake, so that the micro-nano bubble generator 3 draws in air and fully dissolves it with the high-pressure water flow to generate micro-nano bubbles.

[0040] 2. In the active propeller drive stage, the micro-nano bubble releaser 4 sprays high-pressure, high-speed air-containing water into the blade surface of the active propeller blade 9 in the form of a compression port, and uses the water flow impact force to drive the active propeller blade 9 to rotate.

[0041] 3. During the rotation of the driven blade and the water body, after the main power wheel blade 9 rotates, it drives the driven power wheel blade 8 to rotate synchronously on the one hand, and the air-containing water flow is ejected at high speed from the flow restrictor 10 on the other hand; the rotation of the driven power wheel blade 8 generates centrifugal force, causing the surrounding water body to rotate.

[0042] 4. In the directional flow and oxygenation stage, the flow guide hood 7 guides the rotating water body into a forward directional flow through the reverse flow effect; the continuous directional water flow drives the surrounding water body to flow together, forming a flow state in the same direction. At the same time, micro-nano bubbles diffuse in the water body to achieve efficient oxygenation, and finally make the water body into "living water" (oxygen-rich, flowing water body).

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
