[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 2 to Figure 6 As shown, this embodiment proposes an efficient oxygen purification device, including a pure gas housing 12, a plurality of first gas outlets 121 for transferring the purified gas are all opened on the side wall of the pure gas housing 12, and a second gas outlet 124 is opened on the other side of the first gas outlet 121. The pure gas housing 12 is connected to a cover 14 that ensures that the pure gas housing 12 is sealed and performs preliminary filtering on the gas. A gasification component 2 that accelerates the purification of the gas after preliminary filtering is connected between the cover 14 and the second gas outlet 124. The gasification component 2 can continuously compress and decompress the gas injected into the pure gas housing 12. The air is first decompressed, and the water vapor impurities in the air can be separated by the decompression effect, thereby reducing the content of the air. The amount of water is increased to improve the efficiency of oxygen purification, and then the compressed gas is brought into contact with the molecular sieve through compression to separate the oxygen in the air to achieve the purpose of purifying the oxygen. The limit plate 28 that makes piston motion with the inner wall of the pure gas shell 12 is connected to the lower side of the gasification component 2, and the driving component for driving the gasification component 2 is connected to the lower side of the limit plate 28. A number of heating pipes 6 for heating the gas in the pure gas shell 12 are annularly fixedly connected to the pure gas shell 12. The heating pipes 6 can heat and dry the air in the pure gas shell 12 by heating, increase the speed of water vapor separation, and further improve the oxygen purification efficiency. The limit block 17 that cooperates with the gasification component 2 to complete the function is fixedly connected to the inner wall of the pure gas shell 12.

[0028] like Figure 3 to Figure 5As shown, the gasification component 2 includes a limiting sleeve 21, the limiting sleeve 21 is fixedly connected to the limiting disk 28, the pressure column 27 is slidably connected to the limiting sleeve 21, and the end of the pressure column 27 away from the limiting sleeve 21 is fixedly connected to the first sealing plate 24, and the pressure spring 23 is sleeved on the pressure column 27, and the two ends of the pressure spring 23 are respectively abutted against the outer wall of the limiting sleeve 21 and the first sealing plate 24. When the limiting disk 28 moves up, the first sealing plate 24 will abut against the limiting block 17 on the lower side. Under the action of the pressure spring 23, the continued movement of the limiting disk 28 will cause the first sealing plate 24 to be completely closed. The limiting block 17 is pressed against the first sealing plate 24 so that the hole groove on the limiting block 17 is completely blocked, so that a closed cavity is formed between the first sealing plate 24 and the limiting plate 28, and then the limiting plate 28 continues to move upward to continuously compress the gas in the cavity until the vent hole 32 is connected to the first air outlet 121, and this part of the compressed gas contacts the molecular sieve through the first air outlet 121, so that oxygen is separated from the air, and the limiting plate 28 is slidably connected in the limiting sleeve 21, and the negative pressure column 26 is fixedly connected to the limiting plate 28, and the negative pressure column 26 is away from the limiting plate 28. One end of the positioning plate 28 is fixedly connected to the second sealing plate 25, and the negative pressure spring 22 is sleeved on the negative pressure column 26. The two ends of the negative pressure spring 22 are respectively connected to the inner wall of the limiting sleeve 21. When the limiting plate 28 moves downward, the desiccant block 31 will block the first air outlet 121 and drive the second sealing plate 25 to move downward. When the second sealing plate 25 contacts the limiting block 17, the second sealing plate 25 will press the air on the upper side of the limiting block 17 into the cavity between the limiting plate 28 and the second sealing plate 25. As the limiting plate 28 continues to move downward, under the action of the negative pressure spring 22, the second sealing plate 25 will gradually It gradually comes into close contact with the limit block 17, and then blocks the hole groove in the limit block 17, so that the air in the cavity between the limit plate 28 and the second sealing plate 25 is continuously decompressed. During the decompression process, the moisture inside the gas will also decrease as the pressure decreases. This is because moisture usually exists in liquid form under high pressure, but in the decompression process, moisture may be released in gaseous form. Therefore, the decompression treatment can reduce the moisture in the gas to a lower level. At the same time, the desiccant block 31 will absorb and dry this part of the separated water vapor, further improving the air purification efficiency.

[0029] like Figure 3 to Figure 5 As shown, the outer walls of the negative pressure column 26 are tightly fitted with the inner walls of the first sealing plate 24 and the inner walls of the pressure column 27 and are slidably connected. Cylinders and other related manufacturing processes can be used to ensure that air does not escape from the connection between the negative pressure column 26 and the pressure column 27. The upper side surface of the first sealing plate 24 abuts against the lower side surface of the limit block 17, and the lower side surface of the second sealing plate 25 abuts against the upper side surface of the limit block 17, so that the negative pressure column 26 and the pressure column 27 will not interfere with each other during relative movement.

[0030] like Figure 2 and Figure 3As shown, the driving assembly includes a flip block 41 and a motor 5. The flip block 41 is fixedly connected to the side of the limit plate 28 facing the bottom of the pure gas shell 12. The flip block 41 is rotatably connected to the flip plate 43. The end of the flip plate 43 away from the flip block 41 is rotatably connected to the shaking column 42. Both ends of the shaking column 42 are rotatably connected to the pure gas shell 12. The motor 5 is fixedly connected to the outer wall of the pure gas shell 12. The driving shaft of the motor 5 passes through the pure gas shell 12 and is fixedly connected to one end of the shaking column 42. The shaking column 42 is directly driven to rotate by the motor 5, so that the limit plate 28 makes continuous piston motion in the pure gas shell 12, so that the air in the pure gas shell 12 can be repeatedly pressurized and depressurized.

[0031] like Figure 3 to Figure 6 As shown, the insulation tank 123 is opened on the pure gas shell 12, the heating pipe 6 is fixedly connected to the inner wall of the insulation tank 123, and the heating pipe 6 is close to the inner wall of the insulation tank 123 on the side of the axis of the pure gas shell 12. The air in the pure gas shell 12 is dried by heating the pure gas shell 12, so that the water vapor in the air can be absorbed by the desiccant block 31. The gas gathering tank 122 is opened on the pure gas shell 12, and each first air outlet hole 121 is connected with the gas gathering tank 122, so that the gas flowing out of each first air outlet hole 121 is gathered from the gas gathering tank 122 and finally flows out from the second air outlet hole 124. The second air outlet hole 124 is connected with the gas gathering tank 122, and the second air outlet hole 124 is fixedly connected to the air outlet pipe 13 toward the outside. A molecular sieve for separating oxygen is fixedly connected in the air outlet pipe 13, and the oxygen in the air is separated by the molecular sieve.

[0032] like Figure 5 and Figure 6 As shown, several desiccant blocks 31 are fixedly connected to the limiting plate 28, and each sealing block 3 is fixedly connected to the upper side of each desiccant block 31. The desiccant block 31 can absorb the water separated from the oxygen to achieve the purpose of oxygen purification. Each leak hole 32 is respectively opened on each desiccant block 31. When the desiccant block 31 moves up to a certain distance, the leak hole 32 will be connected with the first air outlet 121, so that the gas in the pure gas shell 12 can be converted from a closed state to a flowing state. Each sealing block 3 is in contact with the inner wall of the pure gas shell 12, so that the sealing block 3 can block the first air outlet 121 most of the time, thereby forming a closed space between the limiting plate 28 and the cover 14.

[0033] like Figure 3 and Figure 5 As shown, the cover 14 is threadedly connected to the pure gas housing 12, so that after the pure gas housing 12 is disassembled through the cover 14, the remaining components can be easily replaced to increase the service life of the entire components. The polymer filter element 16 is fixedly connected in the cover 14 to remove impurities and moisture in the oxygen, and the air inlet pipe 15 is fixedly connected to the upper side of the cover 14.

[0034] like Figure 2 and Figure 3 As shown, a plurality of support legs 11 for supporting the pure gas housing 12 are fixedly connected to the lower side of the pure gas housing 12 to support the entire pure gas housing 12 so as to ensure that the temperature inside the pure gas housing 12 is stable and will not be excessively disturbed by the outside world.

[0035] The working principle of this embodiment is:

[0036] First, tighten the cover 14 on the pure gas housing 12, and then inject the raw gas from the gas inlet pipe 15. The raw gas can be pre-processed by the polymer filter element 16, that is, the impurities such as water are initially removed, and then the preliminarily cleaned raw gas is accumulated in the cavity between the cover 14 and the second sealing plate 25. The motor 5 is started to drive the shaking column 42 to rotate, and then the flip plate 43 drives the limit plate 28 to move up and down like a piston on the inner wall of the pure gas housing 12;

[0037] When the limit plate 28 is at the highest point and moves downward: at this time, the second sealing plate 25 has not yet abutted against the side wall of the limit block 17, so the cavity between the cover 14 and the second sealing plate 25 becomes the cavity between the cover 14 and the first sealing plate 24. As the limit plate 28 moves downward, the limit plate 28 gradually abuts against the side wall of the limit block 17, and even abuts against the bottom wall of the limit block 17, which will press a part of the raw gas downward until the limit plate 28 moves down to a length exceeding the length of the pressurizing column 27, the first sealing plate 24 will separate from the limit block 17, so that the raw gas is transferred into the cavity between the second sealing plate 25 and the limit plate 28. Under the action of the negative pressure spring 22, the limit plate 28 can continue to move downward. At this time, the raw gas will be decompressed and dried. The water vapor further separated from the raw gas will be absorbed by the desiccant block 31, so that the impurities in the raw gas will be further removed.

[0038] When the limit plate 28 is at the lowest point and moves upward: the gas that has been decompressed and dried in the previous process moves upward with the limit plate 28. After the first sealing plate 24 abuts against the limit block 17, the air pressure returns to normal. At this time, the cavity is transformed from the cavity between the second sealing plate 25 and the limit plate 28 to the cavity between the first sealing plate 24 and the limit plate 28. The limit plate 28 continues to move upward to pressurize the raw gas in the cavity, and the second sealing plate 25 is gradually reset to facilitate the subsequent replenishment of the raw gas. Until it is compressed to a certain pressure, the sealing block 3 moves to the highest position with the limit plate 28, so that the vent hole 32 is connected to the first outlet hole 121, so that the compressed gas will quickly flow through the first outlet hole 121 and contact with the outlet pipe 13 with a molecular sieve, so that the oxygen in the raw gas is separated. The outlet pipe 13 can be connected with a hose to connect with other higher precision refining equipment to improve the oxygen purity.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
