Description

Technical Field

[0001] The invention relates to the technical field of aeration and oxygenation equipment, in particular to micro-nano aeration and oxygenation equipment. Background Art

[0002] my country has relatively prominent problems such as low per capita water resources, prominent contradiction between supply and demand, pollution of rivers and lakes, and fragile water ecosystems. The increasing scarcity of water resources and the continuous aggravation of water pollution have become a major "bottleneck" problem restricting the sustainable development of my country's social economy.

[0003] Due to the intensification of human activities, the discharge of industrial, agricultural and domestic sewage has increased, and the dilution and purification function of rivers and lakes has been greatly weakened. Especially at present, many large cities, industrial zones and cities are built on riverside or lakeside areas. A large amount of wastewater enters the water body without treatment, exceeding the self-purification limit of the water body. Pollutants are deposited in the water and cannot be effectively degraded, resulting in most rivers and lakes being in a state of eutrophication to varying degrees. It is urgent for social and economic development and ecological environment construction to carry out the protection and restoration of river and lake water ecosystems and effectively improve the status of water environment and water ecosystems.

[0004] In the sewage treatment process, certain methods and equipment are used to force air into the sewage, so that the sewage in the pool contacts the air and is oxygenated, and the liquid is stirred to accelerate the transfer of oxygen in the air to the liquid, prevent the suspended body in the pool from sinking, strengthen the contact between the organic matter in the pool and the microorganisms and dissolved oxygen, and oxidize and decompose the organic matter in the sewage. This kind of equipment that forces oxygenation into the sewage is called an aeration device. However, the tiny bubbles produced by the existing aeration equipment are generally not fully combined with water, and the residence time of the bubbles in the water is generally short. Most of them overflow from the water and are discharged into the atmosphere, and the aeration effect is poor. In addition, the existing aeration equipment is also prone to inhaling larger impurities in the sewage, which is easy to cause blockage. Summary of the invention

[0028] Embodiment 1

[0029] like Figure 1 As shown, the present invention provides a micro-nano aeration and oxygenation device, including a float 1, which can provide sufficient buoyancy for the entire aeration and oxygenation device to ensure that the aeration and oxygenation device can float stably on the water surface. The float 1 is equipped with a vertical downward electric telescopic rod 2, such as Figure 2 As shown, the float 1 is provided with a first through hole 19 in the middle and a second through hole 20 and a third through hole 21 on both sides. The electric telescopic rod 2 is installed on the float 1 through the first through hole 19. The bottom of the electric telescopic rod 2 is connected to a fixing frame 3. The liquid level height of the fixing frame 3 can be flexibly controlled by extending and retracting the electric telescopic rod 2.

[0030] like Figure 1 As shown, the first slide bar 22 and the second slide bar 23 connected to the upper surface of the fixing frame 3 are respectively vertically arranged in the second through hole 20 and the third through hole 21, and the length of the first slide bar 22 and the second slide bar 23 is not less than the full length of the electric telescopic rod 2. Through the limiting effect of the first slide bar 22 and the second slide bar 23, the fixing frame 3 can always move vertically up and down without position deviation, so that the fixing frame 3 can be more firm and stable.

[0031] A double suction pump 5 is fixed below the fixed frame 3 through a connecting rod assembly 4, which can simultaneously inhale water and air, and make the water and air absorbed by the double suction pump 5 be mixed and spun into the pump body of the double suction pump 5 through an impeller. An air inlet pipe 6 is connected to the air inlet of the double suction pump 5, and the other end of the air inlet pipe 6 is connected to a nano air pump 7 fixed on the float 1. Air can be actively blown into the double suction pump 5 through the nano air pump 7 to ensure the supply of air. An inlet pipe 8 is connected to the water inlet of the double suction pump 5, and a magnetic generator 10 is installed on the water inlet pipe 8. The magnetic generator 10 can make the water body enter a high-strength magnetic cutting channel for magnetization to form magnetic water. The magnetic water generated by the magnetic generator 10 has strong permeability, which is conducive to ensuring the full fusion of air and water, and can increase the residence time of microbubbles by several times. A water filter assembly 9 is connected to the other side of the water inlet pipe 8, which can effectively filter the sewage entering the aeration and oxygenation equipment to prevent the aeration and oxygenation equipment from being easily blocked.

[0032] The water filter assembly 9 includes a filter housing 91, which is fixed to the bottom of the fixing frame 3 by a connecting rod assembly 4, so as to ensure that the water filter assembly 9 is installed more stably. A water inlet 92 is provided in the middle of the filter housing 91, and an outer filter screen 93 is installed on the water inlet side of the filter housing 91. The outer filter screen 93 can perform the first filtration treatment on the sewage entering the aeration and oxygenation equipment to prevent larger impurities in the sewage from entering the interior of the aeration and oxygenation equipment.

[0033] A slot 94 is provided on one side of the filter outer shell 91, and a card plate 95 is movably provided at the slot 94. An inner filter screen 96 is provided in the middle of the card plate 95. The area of ​​the inner filter screen 96 is larger than the cross section of the water outlet 92. The inner filter screen 96 can intercept and filter the sewage entering the aeration and oxygenation equipment for the second time, which can further improve the anti-blocking effect. A baffle 97 is connected to the outside of the card plate 95, and a pull-out handle 98 is provided on the outside of the baffle 97, which can facilitate the removal of the card plate 95 for cleaning. The periphery of the inner filter screen 96 is provided with a sealing rubber pad 99 installed on the front and rear sides of the card plate 95, which can ensure that the sewage is filtered by the inner filter screen 96 to the maximum extent and then flows into the pump body of the double-suction pump 5.

[0034] A small molecule generator 11 is provided at the water outlet of the double-suction pump 5. The small molecule generator 11 can produce small molecule water with strong permeability, and can further refine the water flowing out of the double-suction pump 5, so that the small molecule water produced by the small molecule generator 11 can allow the microbubbles to retain oxygen in the water for a longer time.

[0035] The other end of the small molecule generator 11 is connected with a gas dissolving tank 12 fixed below the fixed frame 3 by a connecting rod assembly 4, which can also ensure that the gas dissolving tank 12 is firmly fixed below the fixed frame 3. Several groups of clockwise spoilers 121 and counterclockwise spoilers 122 are alternately distributed in the gas dissolving tank 12, so that water can be stirred and changed in the gas dissolving tank 12 for many times, and the full fusion of microbubbles and water on one side can be ensured. The other end of the gas dissolving tank 12 is provided with a venturi tube 13, and the decompression injection of the venturi tube 13 can further enhance the fusion effect of microbubbles and water. Through multiple fusions and refinement in a variety of different ways, it can be ensured that microbubbles can be refined to micro-nano level, which fully ensures the efficient fusion of microbubbles and water.

[0036] The water outlet of the venturi tube is connected to a water outlet pipe 14, and the water outlet pipe 14 is fixed to the bottom of the fixed frame 3 through a connecting rod assembly 4 to fix the water outlet pipe 14. A dissolved oxygen sensor 15 installed at the bottom of the fixed frame 3 is provided above the water outlet pipe 14, which can detect the dissolved oxygen content in the water near the water outlet pipe 14 in real time. A temperature sensor 16 and a water level sensor 17 are also installed at the bottom of the fixed frame 3, which can detect the water temperature and the water level height below the aeration and oxygenation equipment in real time. A controller 18 is installed on the float 1, which can adjust the operating state of the aeration and oxygenation equipment according to the data collected by each sensor and the control of the operator.

[0037] Therefore, the present invention adopts the above-mentioned micro-nano aeration and oxygenation equipment to fully integrate the tiny bubbles with water, so that the tiny bubbles can stay in the water for a long time and have a good flotation effect, which can significantly improve the dissolved oxygen level of the local water body and promote the water body reoxygenation function.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
