Description

Technical Field

[0001] This invention relates to the field of anti-icing technology, and more particularly to a microbubble anti-icing device. Background Technology

[0002] Ice layers can create deformation forces that severely impact the safety of hydraulic structures such as gates, piers, rubber dams, and embankments. Water seeping into concrete can also cause freeze-thaw damage. Therefore, ice prevention in northern winters is crucial for ensuring the safe operation of water conservancy projects. This necessitates an ice-prevention device to eliminate ice damage to hydraulic structures during the ice season. Existing ice prevention measures vary. Compressed air blowing is effective, and the air hose is easier to install and disassemble than a water pump. However, the air compressor has a high power consumption, reaching 18.5 kilowatts per unit, resulting in significant noise. Pressure water jetting can meet ice prevention requirements, but the range of a single pump is limited, often requiring multiple pumps to operate simultaneously. This method also has high power consumption, is inconvenient to install and disassemble, has a high failure rate, and requires a certain water depth. Furthermore, water jets can freeze onto surrounding walls. Electric heating methods offer rapid ice melting and are suitable for small-scale ice prevention scenarios, but not for larger water surfaces. When long circuits require wiring, there is a risk of electric shock, and energy consumption is high.

[0003] In summary, existing anti-icing equipment suffers from problems such as high power consumption, inconvenient installation and disassembly, and high failure rate, which in turn increases maintenance costs. Summary of the Invention

Therefore, they should not be construed as limitations on this invention.

[0035] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] The schematic diagram in this invention shows only one microbubble assembly 10 corresponding to one gas delivery pipe assembly 20, and one gas delivery pipe assembly 20 is connected to the gas supply pipeline assembly 30.

[0037] Reference Figures 1 to 7 This invention provides a microbubble anti-icing device that can solve the problems of existing anti-icing devices, such as high power consumption, inconvenient installation and disassembly, high failure rate, and thus increased maintenance costs.

[0038] The present invention provides a microbubble anti-icing device, comprising multiple microbubble components 10, multiple air supply pipe components 20, air supply pipeline components 30, and a fan 40. Each microbubble component 10 is provided with multiple microbubble holes 11. One air supply pipe component 20 corresponds to one microbubble component 10, wherein one end of the air supply pipe component 20 is detachably connected to the microbubble component 10, and the air supply pipe component 20 and the microbubble component 10 are internally connected. The other ends of the multiple air supply pipe components 20 are respectively connected to the side wall of the air supply pipeline components 30, and the air supply pipeline components 30 are all internally connected to the multiple air supply pipe components 20. The air supply pipeline components 30 are connected to the fan 40 so that the fan 40 delivers compressed air to the air supply pipeline components 30.

[0039] The microbubble assembly 10 can be disc-shaped. The height of the microbubble assembly 10 can be 10cm-20cm, and the diameter can be 60cm-80cm. These dimensions can be determined based on actual conditions and are not limited here. Furthermore, the number of microbubble assemblies 10, gas delivery pipe assemblies 20, and blowers 40, as well as the length of the gas supply pipe assembly 30, are not limited here and can be determined based on actual conditions.

[0040] Furthermore, the blower 40 uses a three-lobe roots blower as the power source for compressed air. The three-lobe roots blower adopts a three-lobe rotor structure, which has low vibration and low noise. The impeller and shaft are an integral structure and the impeller has no wear. The performance of the three-lobe roots blower remains unchanged for a long time and can operate continuously for a long time. The three-lobe roots blower has a large volume utilization rate, high volumetric efficiency, and a compact structure, and the installation method is flexible and versatile.

[0041] This invention provides a microbubble anti-icing device. Multiple microbubble components 10 are internally connected to air supply pipe components 20. Air supply pipe components 30 are also internally connected to the multiple air supply pipe components 20. The air supply pipe components 30 are connected to a fan 40, allowing the fan 40 to deliver compressed air to the air supply pipe components 30. The air then passes through the multiple air supply pipe components 20 until it reaches the corresponding microbubble component 10. The air flows out through multiple microbubble holes 11, releasing a large number of micron-sized microbubbles into the water, rapidly and effectively increasing the gas content in the water and simultaneously propelling water movement. Because of their small size and low buoyancy, the bubbles stay in the water for a long time, rise slowly, and continuously diffuse outwards. Under the influence of the movement of a large number of microbubbles, the water with higher temperature at the bottom moves towards the surface, increasing the surface water temperature and melting the ice layer, thus preventing the formation of ice in the water and solving the anti-icing problem. Furthermore, the microbubble assembly 10, the air supply pipe assembly 20, the air supply pipeline assembly 30, and the blower 40 are detachably connected, making installation convenient. Compressed air is provided by the blower 40, which has low power consumption. This invention solves the problems of existing anti-icing equipment, such as high power consumption, inconvenient installation and disassembly, high failure rate, and increased maintenance costs.

[0042] Reference Figures 2 to 3 Optionally, the microbubble assembly 10 includes a microbubble support 12 and a microbubble tube 13;

[0043] The microbubble support 12 is detachably connected to the microbubble tube 13, and the microbubble tube 13 is provided with multiple microbubble holes 11.

[0044] When both the microbubble support 12 and the microbubble tube 13 are disc-shaped, the microbubble support 12 is a disc welded from plastic-coated iron wire, and the microbubble tube 13 is a ring-shaped nano-aeration tube. In use, the microbubble assembly 10 is suspended into the bottom water using a rope for aeration. The pore diameter of the microbubble holes 11 is φ0.03mm-φ0.06mm; the arrangement density of the microbubble holes 11 is 700-1200 holes / meter; and the diameter of the microbubbles is 0.5mm-2mm.

[0045] Reference Figure 2 Optionally, the microbubble pores 11 are shaped to extend from the middle to both ends, and their size gradually increases.

[0046] The shape of the microbubble pores 11 makes it easier to form small bubbles, which stay in the water for a longer time, thus resulting in a better anti-icing effect.

[0047] Reference Figure 1 Optionally, the gas pipeline assembly 20 includes a first connecting pipe 21, a second connecting pipe 22, a one-way valve 23, and a connecting joint 24;

The other end of the second connecting pipe 22 is connected to the side wall of the gas supply pipeline assembly 40.

[0049] The first connecting tube 21 and the second connecting tube 22 are both plastic hoses, and the connecting joint 24 is a plastic connecting joint, which can realize the quick connection between the first connecting tube 21 and the microbubble tube 13 and is easy to assemble and disassemble; the one-way valve 23 allows the air in the second connecting tube 22 to flow into the first connecting tube 21 in one direction, avoiding air backflow.

[0050] Reference Figures 6 to 7 Optionally, the gas supply line assembly 30 includes a gas supply line 31 and a plurality of gas nozzle seals 32;

[0051] The side wall of the gas supply pipeline 31 is provided with multiple connection ports 310. The large ends of multiple air nozzle seals 32 are respectively embedded in the gas supply pipeline 31 through the connection ports 310, and the small ends of the air nozzle seals 32 are detachably connected to the other end of the second connecting pipe 22.

[0052] Among them, the air supply line 31 is a plastic hose, which allows the large end of the air nozzle seal 32 to be embedded in the air supply line 31 through the connection port 310 to achieve a sealing effect and prevent air leakage.

[0053] Reference Figure 1 Optionally, it also includes: a fixing member 50, wherein the microbubble support 12 and the microbubble tube 13 are detachably connected by the fixing member 50, and the microbubble tube 13 is located above the microbubble support 12.

[0054] The fastener 50 can be a buckle or a clamp, which is convenient for installation or disassembly.

[0055] Reference Figures 4 to 5 Optionally, the inner side of the microbubble tube 13 is provided with a concave groove, and the microbubble tube 13 is wrapped around the microbubble support 12 through the concave groove.

[0056] The microbubble tube 13 is wrapped around the outside of the microbubble support 12, which increases the area of ​​the microbubble tube 13 and thus increases the number of microbubble holes 11, resulting in a better anti-icing effect.

[0057] Reference Figure 5 Optionally, the microbubble support 12 has a hollow structure.

[0058] When the microbubble support 12 has a hollow structure, the inner side of the microbubble tube 13 can also be provided with multiple microbubble holes 11, so that the microbubbles can be released from the hollow structure, the number of microbubbles increases, and the anti-icing effect is better.

[0059] Furthermore, the microbubble support 12 contains multiple ceramic beads. The diameter of the ceramic beads is preferably φ0.5mm to 1mm.

[0060] Multiple ceramic beads are used to further compress the microbubbles, making the microbubbles even smaller and thus improving the anti-icing effect.

[0061] Reference Figures 4 to 5 Optionally, it also includes: an air blowing device 60, which is fixedly mounted on the microbubble support 12. The air blowing device 60 is provided with a plurality of air blowing holes 61. One end of the first connecting pipe 21 is detachably connected to the air blowing device 60 through one connector of the connecting joint 24. The first connecting pipe 21 and the air blowing device 60 are internally connected. The connecting joint 24 is a three-way connecting joint. The other connector of the connecting joint 24 is detachably connected to the microbubble tube 13. The microbubble tube 13 and the air blowing device 60 are arranged in parallel.

[0062] If the microbubble support 12 is disc-shaped, the air blowing device 60 can be set in the middle of the microbubble support 12. The first connecting pipe 21 is internally connected to the air blowing device 60, so that air enters the air blowing device 60 and is then ejected from the air blowing hole 61, blowing the bubbles generated in the microbubble support 12 further, thereby increasing the anti-icing area.

[0063] Reference Figure 5 Optionally, the air blowing device 60 includes a plurality of connecting posts 62 and an air blowing pipe 63;

[0064] The air blowing tube 63 is fixedly mounted on the microbubble support 12 by multiple connecting posts 62. The air blowing tube 63 is provided with multiple air blowing holes 61. One end of the first connecting tube 21 is detachably connected to the air blowing tube 63 through a connector of the connecting joint 24. The first connecting tube 21 and the air blowing tube 63 are internally connected. The microbubble tube 13 and the air blowing tube 63 are arranged in parallel.

[0065] If the microbubble support 12 is disc-shaped, the air blowing pipe 63 is also disc-shaped. Multiple connecting posts 62 are radially distributed along the center of the microbubble support 12, and the air blowing pipe 63 is fixed in the middle of the microbubble support 12 through the connecting posts 62.

[0066] Working process: When the microbubble anti-icing equipment is applied to the area around a dam for anti-icing purposes, the air supply pipeline assembly 30 is laid around the outer fence of the dam. The air delivery pipe assembly 20 and the microbubble assembly 10 are suspended in the water using ropes. The air delivery pipe assembly 20 is equipped with a float, and a preset length of the air delivery pipe assembly 20 is left above the water surface to automatically adjust as the water level rises or falls. After installation, the blower 40 is started, which delivers compressed air to the air supply pipeline assembly 30, then sequentially through multiple air delivery pipe assemblies 20 until it reaches the corresponding microbubble assembly 10. The air flows out through multiple microbubble holes 11, and then into the water. The release of numerous micron-sized microbubbles rapidly and effectively increases the gas content in the water, while simultaneously propelling water movement. Because they are formed at the bottom of the water, the internal temperature of the microbubbles is equal to the temperature at the bottom, which is higher than the surface temperature. As the microbubbles float, they burst at the water surface, releasing their internal heat and raising the surface temperature. Due to their small size and low buoyancy, the microbubbles remain in the water for a long time, rise slowly, and continuously diffuse in all directions. Under the influence of the movement of numerous microbubbles, the warmer water at the bottom moves towards the surface, increasing the surface water temperature and melting ice layers, thus preventing the formation of ice in the water and solving the ice-prevention problem.

[0067] In summary, the microbubble anti-icing device provided by this invention involves internal communication between multiple microbubble components 10 and air supply pipe components 20, internal communication between air supply pipe components 30 and multiple air supply pipe components 20, and connection of air supply pipe components 30 to a fan 40. The fan 40 delivers compressed air to the air supply pipe components 30, which then sequentially passes through multiple air supply pipe components 20 until reaching the corresponding microbubble components 10. The air flows out through multiple microbubble holes 11, releasing a large number of micron-sized microbubbles into the water, rapidly and effectively increasing the gas content in the water and simultaneously propelling water movement. Because of their small size and low buoyancy, microbubbles stay in water for a long time, rise slowly, and continuously diffuse outwards. Under the influence of the movement of numerous microbubbles, the warmer water at the bottom moves towards the surface, increasing the surface water temperature and melting the ice layer, thus preventing the formation of ice in the water and solving the anti-icing problem. Furthermore, the microbubble assembly 10, the air supply pipe assembly 20, the air supply pipeline assembly 30, and the blower 40 are detachably connected, making installation convenient. Compressed air is supplied by the blower 40, which has low power consumption. This invention solves the problems of existing anti-icing equipment, such as high power consumption, inconvenient installation and disassembly, high failure rate, and increased maintenance costs.
