Description

Technical Field

[0001] The invention relates to the field of underwater applications, in particular to an air-explosion type underwater air efficient extraction device. Background Art

[0002] For thousands of years, people have dreamed of swimming in the water like fish without the need to worry about breathing. In particular, diving enthusiasts always keep an eye on the oxygen level in their tanks during their underwater dives. There is a large amount of air in the water, and making a scuba tank that can extract air quickly and efficiently from the water is the dream of many people.

[0003] Let's talk about the history of artificial gills first: Since the 1960s, Cussler of the Department of Chemical Engineering at the University of Minnesota has proposed the idea of ​​using membrane materials such as polydimethylsiloxane to separate dissolved oxygen from water. He even made a prototype that can breathe for a puppy. But it is far from the level of breathing for humans. In the 1990s, Japan's Fuji Systems also made an artificial gill to show how great their new generation of asymmetric polydimethylsiloxane is. However, its size is very large, more than the size of a refrigerator. During the demonstration, it needs to be pushed forward in the water to get enough oxygen, and it only maintains the normal breathing of the diver for 18 minutes.

[0004] Since the 20th century, at least two groups have conducted serious scientific research on artificial gills. The Kiyotaka Sakai group of the Department of Chemical Engineering at Waseda University published several articles from 2003 to 2005. The general principle is to use hydrophobic hollow fiber membranes as artificial gills, with the outside of the membrane in contact with the external water body, and a pump to drive the oxygen-enriched liquid through the membrane, and then release the oxygen in the oxygen-enriched liquid from the other side by heating or light. However, no matter how it is optimized, it is impossible to reduce the energy consumption of maintaining this system to provide a person with enough oxygen for normal breathing (just at rest) to less than 150W. Although the source of oxygen has been solved in theory, the power supply has become a problem.

[0005] Harihara Baskaran from the Department of Chemical Engineering at Case Western Reserve University in the United States has also received funding from the US Navy to cooperate with other companies to develop artificial gills. Their idea is to use microfluidic chips to replace hollow fiber membranes as the gill bodies of artificial gills. The advantage of doing this is that because microfluidic chips are "printed" through photolithography technology, the shape of the pipe can be designed to maximize efficiency. In fact, Case Western Reserve University has also tried to use this technology to realize artificial lungs. However, this project eventually came to nothing. The cost of microfluidic chip processing is much higher than that of hollow fiber membranes, and how to integrate so many microfluidic chips is also a problem. In addition, a pump is still needed to drive water through these microchannels.

[0006] The patent invention discloses a method for extracting air from water, which can extract air from water with low energy consumption and directly supply it to divers or submarines. Summary of the invention

[0007] The purpose of the present invention is to provide an air-explosion type underwater air efficient extraction device, which can efficiently and quickly extract air from the water, thereby meeting the oxygen needs of people working and living underwater, thereby expanding the space for human living.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an air-explosion type water air efficient extraction device, comprising a vaporization chamber arranged in a vertical direction, a tapered cover is connected to the top of the vaporization chamber, a gas collecting cover is arranged above the tapered cover, a gas output pipe is connected to the top of the gas collecting cover, a gas collecting cylinder connected to the gas output pipe is arranged in the gas collecting cover, air holes are evenly arranged on the side wall of the gas collecting cylinder, a gas collecting cover is arranged at the bottom of the gas collecting cylinder, and an air-explosion mechanism is arranged on the vaporization chamber;

[0009] The air-blast mechanism includes a water inlet hole arranged on one side of the vaporization chamber, a water outlet hole directly opposite to the water inlet hole is arranged on the other side of the vaporization chamber, a waterproof driving motor is evenly fixed on the side of the vaporization chamber, the driving motor is connected to a driving shaft, and the driving shaft is connected to a propeller that drives water to flow from the water inlet hole to the water outlet hole.

[0010] Through the above technical scheme, the waterproof driving motor drives the driving shaft and the propeller to rotate, so that water flows from the water inlet to the water outlet; when the propeller rotates, a local vacuum (or a pressure lower than that of the surrounding water) will be generated on the back of the blade. Since the water pressure of this part decreases rapidly, the air dissolved in the water will escape, thereby generating a large number of bubbles; the generated bubbles gradually rise in the vaporization chamber and gradually enter the gas collecting hood through the tapered hood. When the gas in the gas collecting hood gradually gathers, the pressure of the gas increases, thereby discharging all the moisture in the gas collecting hood, thereby completing the collection of air; through the gas collection cylinder and the air hole in the gas collecting hood, the gas flows into the gas output pipe, and the setting of the gas collecting cover can play a role in preventing water from splashing; in summary, the device can use the rotation of the propeller to make the air escape from the water and collect it well, which can meet the oxygen demand for underwater work and life. Compared with other oxygen production methods, it has the advantage of low cost.

[0011] Preferably, the position of the water outlet is higher than the position of the water inlet.

[0012] Through the above technical solution, the position of the water outlet is higher than that of the water inlet, so the water flow passing through the propeller has a longer flow path in the vaporization chamber, which is more conducive to the aggregation of bubbles in the vaporization chamber and is conducive to increasing the total collection amount of bubbles.

[0013] Preferably, a filter screen is provided between the tapered hood and the air collecting hood.

[0014] Through the above technical solution, the filter net can prevent debris in the water from entering the air collecting hood, which is conducive to the long-term use of the device.

[0015] Preferably, the gas output pipe is connected to an automatic pressurizing mechanism located in the gas collecting hood.

[0016] Through the above technical solution, the automatic pressurizing mechanism can make the gas in the gas collecting hood have a certain working pressure after being accumulated for a period of time, so as to better complete the use of the collected gas.

[0017] Preferably, the automatic pressurizing mechanism comprises a vertically arranged switch cylinder connected to the gas output pipe, a switch hole is arranged on the side of the switch cylinder, a switch piston is sealingly and slidingly connected inside the switch cylinder, a switch rod is connected below the switch piston, and a float is connected to the lower end of the switch rod.

[0018] Through the above technical solution, when air extraction begins, the bubbles in the gasification chamber float up in the water and move to the gas collecting hood to gather. The gas gradually gathers and the gas pressure increases. Therefore, the water level begins to drop accordingly, and the float and the switch piston also begin to drop. During the descent, the switch hole can connect the internal space of the gas collecting hood with the internal space of the switch cylinder, so that the gas can be output and used from the gas output pipe after the pressurization is completed.

[0019] Preferably, a secondary stirring structure is evenly arranged below the filter screen, and the secondary stirring structure includes evenly arranged tension springs, and counterweights are evenly arranged below the tension springs.

[0020] Through the above technical solution, due to the turbulence below the filter, the turbulence will drive the irregular movement of the tension spring and the counterweight, thereby producing a certain stirring effect on the liquid again, which is conducive to the aggregation of small bubbles into large bubbles, thereby completing the aggregation of bubbles more quickly.

[0021] Preferably, spoiler blades are evenly arranged on the tension spring.

[0022] Through the above technical solution, the spoiler blade can enhance the stirring effect of the tension spring.

[0023] Preferably, the counterweight is an inverted cone-shaped counterweight.

[0024] Through the above technical solution, the side area of ​​the inverted cone-shaped counterweight is larger and is more easily affected by turbulence, thereby better playing the role of stirring.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) The device can utilize the rotation of the propeller to cause air to escape from the water and collect it well, thus meeting the oxygen demand for underwater work and life. Compared with other oxygen production methods, it has the advantage of low cost;

[0027] (2) The position of the water outlet is higher than that of the water inlet, so that the drive shaft is arranged in an inclined upward direction. Therefore, the water flow passing through the propeller has a longer flow path in the vaporization chamber, which is more conducive to the accumulation of bubbles in the vaporization chamber and is conducive to increasing the total amount of bubbles collected;

[0028] (3) The automatic pressurizing mechanism enables the gas in the gas collecting hood to have a certain working pressure after a period of accumulation, thereby better completing the use of the collected gas;

[0029] (4) Due to the turbulence under the filter, the turbulence will drive the irregular movement of the tension spring and the counterweight, thereby stirring the liquid again, which is conducive to the aggregation of small bubbles into large bubbles, thereby completing the aggregation of bubbles more quickly.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-5 , an embodiment provided by the present invention:

[0038] An air-explosion type efficient extraction device for air in water includes a vaporization chamber 1 arranged in the vertical direction, a tapered hood 2 is connected to the top of the vaporization chamber 1, and a gas collecting hood 3 is arranged above the tapered hood 2. A filter screen 13 is arranged between the tapered hood 2 and the gas collecting hood 3. The filter screen 13 can prevent debris in the water from entering the gas collecting hood 3, which is conducive to the long-term use of the device. A gas output pipe 4 is connected to the top of the gas collecting hood 3, a gas collecting tube 5 connected to the gas output pipe 4 is arranged in the gas collecting hood 3, air holes 6 are evenly arranged on the side wall of the gas collecting tube 5, a gas collecting cover 7 is arranged at the bottom of the gas collecting tube 5, and an air-explosion mechanism is arranged on the vaporization chamber 1.

[0039] The air explosion mechanism includes a water inlet 8 arranged on one side of the vaporization chamber 1, a water outlet 9 arranged on the other side of the vaporization chamber 1 and facing the water inlet 8, and a waterproof driving motor 10 is evenly fixed on the side of the vaporization chamber 1, and the driving motor 10 is connected to a driving shaft 11, and the driving shaft 11 is connected to a propeller 12 for driving water to flow from the water inlet 8 to the water outlet 9. In this embodiment, the position of the water outlet 9 is higher than the position of the water inlet 8. The position of the water outlet 9 is higher than the position of the water inlet 8, so that the water flow passing through the propeller 12 has a longer flow path in the vaporization chamber 1, which is more conducive to the aggregation of bubbles in the vaporization chamber 1 and is conducive to increasing the total collection amount of bubbles.

[0040] The working principle of the device is as follows: the waterproof driving motor 10 drives the driving shaft 11 and the propeller 12 to rotate, so that water flows from the water inlet 8 to the water outlet 9; when the propeller 12 rotates, a local vacuum (or a pressure lower than that of the surrounding water) will be generated on the back surface of the blade. Since the water pressure of this part decreases rapidly, the air dissolved in the water will escape, thereby generating a large number of bubbles; the generated bubbles gradually rise in the vaporization chamber 1, and enter the gas collecting hood 3 through the tapered hood 2. When the gas in the gas collecting hood 3 gradually gathers, the pressure of the gas increases, thereby discharging all the moisture in the gas collecting hood 3, thereby completing the collection of air; through the gas collecting tube 5 and the air hole 6 in the gas collecting hood 3, the gas flows into the gas output pipe 4, and the setting of the gas collecting cover 7 can prevent water from splashing.

[0041] In addition, the following improvements are made in this embodiment:

[0042] 1. The gas output pipe 4 is connected to an automatic pressurizing mechanism located in the gas collecting hood 3. The automatic pressurizing mechanism can make the gas in the gas collecting hood 3 have a certain working pressure after being gathered for a period of time, so as to better complete the use of the collected gas.

[0043] The automatic pressurizing mechanism includes a vertically arranged switch cylinder 14 connected to the gas output pipe 4, a switch hole 15 is arranged on the side of the switch cylinder 14, a switch piston 16 is sealed and slidably connected in the switch cylinder 14, a switch rod 17 is connected below the switch piston 16, and a float 18 is connected to the lower end of the switch rod 17. When air extraction begins, the bubbles in the gasification chamber 1 float in the water and move to the gas collecting hood 3 to gather. The gas gradually gathers and the gas pressure increases, so the water level also starts to drop accordingly, so the float 18 and the switch piston 16 also start to drop. During the drop, the switch hole 15 can connect the internal space of the gas collecting hood 3 with the internal space of the switch cylinder 14, so that the gas can be output and used from the gas output pipe 4 after the pressurization is completed.

[0044] 2. A secondary stirring structure is evenly arranged below the filter 13, and the secondary stirring structure includes evenly arranged tension springs 19, and a counterweight 20 is evenly arranged below the tension spring 19. Since there is turbulence below the filter 13, the turbulence will drive the tension spring 19 and the counterweight 20 to move irregularly, thereby generating a certain stirring effect on the liquid again, which is conducive to the aggregation of small bubbles into large bubbles, thereby completing the aggregation of bubbles more quickly.

[0045] 3. Turbulator blades 21 are evenly arranged on the tension spring 19. Turbulator blades 21 can enhance the stirring effect of the tension spring. The counterweight 20 is an inverted cone-shaped counterweight 20. The inverted cone-shaped counterweight 20 has a larger side area and is more susceptible to turbulence, thereby better playing the role of stirring.

[0046] In summary, the beneficial effects of the present invention are as follows: (1) the device can utilize the rotation of the propeller 12 to allow air to escape from the water and collect it well, thereby meeting the oxygen demand for underwater work and life. Compared with other oxygen production methods, it has the advantage of low cost; (2) the position of the water outlet 9 is higher than the position of the water inlet 8, so that the drive shaft 11 is arranged in an inclined upward direction, so that the water flow passing through the propeller 12 has a longer flow path in the vaporization chamber 1, which is more conducive to the aggregation of bubbles in the vaporization chamber 1 and is conducive to increasing the total amount of bubbles collected; (3) the automatic pressurization mechanism can enable the gas in the gas collecting hood 3 to have a certain working pressure after a period of aggregation, thereby better completing the use of the collected gas; (4) due to the turbulence at the position below the filter 13, the turbulence will drive the irregular movement of the tension spring 19 and the counterweight 20, thereby again producing a certain stirring effect on the liquid, which is conducive to the aggregation of small bubbles into large bubbles, thereby completing the aggregation of bubbles more quickly.
