example 1-4

[0038] Oxidized urea synthesis Mix food-grade urea, hydrogen peroxide aqueous solution, stabilizer, and coating agent, stir at 35 degrees Celsius for a certain period of time, and precipitate product crystals at low temperature. In the stage of solid precipitation, keep stirring to make the crystal particles small and uniform. The crystal particle size was obtained by visually observing the diameter of 10 crystal particles with a low-power microscope, and repeated 3 times. In the vacuum filtration stage, the filtration time is controlled to obtain urea peroxide with different mother liquor contents. The actual mother liquor content is about 1%-12%. The specific results are shown in Table 1.

[0039] By example 1-4 see stirring speed has direct impact on the crystal particle size that generates when urea peroxide crystallization. The crystal particle size has a direct impact on the substrate mother liquor content, molding pressure, shape, physical stability and dissolution r...

example 5-10

[0044] Examples 5-10 were carried out with the results of Example 3. In the stage of oxidized urea compression molding, because the pressure is different from that of the mold, the remaining amount of mother liquor and the physical stability of the particles after molding are also different. The final substrate mother liquor content is obtained by subtraction method after drying under reduced pressure at 50 degrees centigrade under 0.05 atmospheric pressure. The physical stability is obtained by the actual loading of the prototype, and the integrity of the 2-meter free fall after 2 drops. The actual results are shown in Table 2.

[0045] Table 2. Example 5-10 Experimental Results

[0046]

[0047] From examples 5-10, it can be seen that the molding conditions of the substrate have a direct impact on the mother liquor content and physical stability of the substrate. A substrate with a moderate mother liquor content can effectively increase the overall available oxygen con...

example 11-14

[0049] Examples 11-13 were carried out with the results of Example 9. The measured effective oxygen content of Example 9 is 19.7%. Add a certain amount of water / ethylene glycol solvent and catalyst into a container containing 100 g of a honeycomb-type oxygen-generating substrate at a room temperature of 25 degrees Celsius. Measure the solution temperature and oxygen generation rate in the vessel. Add example 14 as a contrast, and the contrast oxygen-generating substrate is honeycomb sodium peroxycarbonate.

[0050] Table 3. Example 11-14 Experimental Results

[0051]

[0052] The mass ratio of solvent and urea peroxide has a direct impact on system temperature and oxygen generation rate. The larger the amount of solvent used, the smaller the temperature fluctuation during the oxygen production process of the system, and the more stable the oxygen generation rate, but too much solvent will destroy the portability of the device. The mass ratio of solvent to urea peroxide ...

Abstract

The invention relates to a portable oxygen production apparatus, which is characterized in that the inner part of the portable oxygen production apparatus is separated to an upper solvent chamber and a lower substrate chamber by an interface layer, a rubber membrane is provided in the solvent chamber, a solvent and a catalyst are filled in the rubber membrane, a compression molding oxygen production substrate is filled in the substrate chamber, a tunnel of the interface layer is communicated to an upper chamber body and a lower chamber body, and an oxygen channel is composed of the tunnel and a bottle cap, a firing pin button and an air filtering cotton are attached outside the solvent chamber, a gravity valve is attached in the substrate chamber, and the upper part of the substrate chamber is combined with the bottle cap in a sealing mode. A heat absorption substance is not required by the apparatus, and solvent amount accounts for less than 30% of volume and weight of the whole apparatus. After the rubber membrane is impaled by the firing pin button, the solvent and a catalyst are released to the substrate chamber, is contacted to the oxygen production substrate to generate oxygen, and then oxygen is discharged by a gas-guide tube. The oxygen production apparatus has the characteristics of passive portable performance, light weight and small volume, and can be widely used for first aid, high altitude anoxia, and recovery and health care after violent muscle power consumption.

Description

Technical field: [0001] The invention relates to an oxygen generator, which belongs to the second category of medical equipment, and is classified as 6854-9 technical background: [0002] Oxygen is one of the basic substances necessary for the human body and plays an irreplaceable key role in life activities. With the acceleration of industrialization and the improvement of material living standards, there are more and more factors that cause sudden hypoxia in the human body, such as obesity, human circulatory system disorders, atmospheric inhalable particles, and other traditional factors, including age-induced Physical weakness, high altitude and severe physical exertion, etc. More and more people need portable and reliable oxygen generators to provide health protection to deal with sudden hypoxia that may occur anytime and anywhere. At present, there are many civilian-grade oxygen generators on the market, which are mainly divided into active physical adsorption oxygen ...
