As shown in FIG. 1, the present invention includes an outer tube 13 and end caps 15, 2 at front and rear ends. The front end cover 15 is provided with a nitrogen outlet 14. The rear end cover is provided with an air inlet 11. A strong magnetic oxygen-nitrogen separator 5 is arranged at the center of the inner cavity of the outer cylinder 13, an oxygen-enriched collecting pipe 9 of the strong magnetic oxygen-nitrogen separator 5 penetrates out from the center holes of the front end cover 15 and the rear end cover 15, and the front end of the strong magnetic oxygen-nitrogen separator is provided with an oxygen-enriched gas outlet 19.
As shown in fig. 1 to 8, the strong magnetic oxygen-nitrogen separator 5 comprises an oxygen-enriched collection pipe 9 and a plurality of permanent magnets 6; two ends of the oxygen-enriched collecting pipe 9 penetrate through central holes of the front end cover 15 and the rear end cover 2, are connected to the front end cover 15 and the rear end cover 2 through a front end cover compression nut 8, a rear end cover compression nut 1 and threads at two ends, and simultaneously compress the front end cover 15 and the rear end cover 2 on the outer cylinder 13; the back end of the oxygen-enriched collecting pipe 9 is sealed by a special screw cap, the front end is an oxygen-enriched gas outlet 19, and a collecting hole 9-1 is formed on the front pipe body; the permanent magnet 6 is sleeved outside the oxygen-enriched collecting pipe 9, and the permanent magnets 6 sleeved at the rear part of the oxygen-enriched collecting pipe 9 are separated by a permanent magnet spacer 18; the permanent magnets 6 sleeved at the front part in the oxygen enrichment collecting pipe are separated by an oxygen enrichment channel gap supporting piece 16, and the oxygen enrichment channel gap supporting piece 16 and the spacer piece joint structure form a gap channel 16-1 communicated with the collecting hole 9-1. Thus, an air inlet 11, an air flow channel 12 (a gap between the outer side of the strong magnetic oxygen-nitrogen separator 5 and the inner wall of the outer cylinder 13), an oxygen enrichment collection channel 17 (a channel between the front permanent magnet 6 in the oxygen enrichment collection pipe 9 and the inner cavity of the outer cylinder 13), a gap channel 16-1, a collection hole 9-1 and an oxygen enrichment outlet 19 are formed. The strong magnetic oxygen-nitrogen separators are arranged in parallel, so that the flow rate of the oxygen-enriched gas can be improved, and the strong magnetic oxygen-nitrogen separators are arranged in series, so that the concentration of the oxygen-enriched gas can be effectively improved. The permanent magnet 6 is formed by superposing three permanent magnets, and in order to improve the magnetic field gradient of the strong magnetic oxygen-nitrogen separator 5, two adjacent permanent magnets 6 are oppositely arranged in the same pole. The outer cylinder 13 and the oxygen-enriched collecting pipe 9 are made of magnetism-isolating materials.
As shown in fig. 1, 9 and 10, an adjusting shim 4 and a flow equalizing disc 3 are sequentially arranged between a back-end pressing nut 21 and a rearmost-end permanent magnet 6 of the strong magnetic oxygen nitrogen separator, and flow equalizing holes 3-1 with symmetrical and equal diameters are formed in the flow equalizing disc 3. Their function is: the flow equalizing disc 3 can equalize the flow of the air entering from the air inlet 11, so that the air is prevented from entering from one side in a centralized manner; the shim 4 can adjust the tightness between the permanent magnets 6. A pressing gasket 7 is arranged between the outer pressing nut 8 of the front end cover and the outer side of the front end cover 15; and a pressing gasket 7 is arranged between the outer pressing nut 1 of the rear end cover and the outer side of the rear end cover 2, and is used for pressing the front end cover 15 and the rear end cover 2 at two ends of the outer cylinder 13.
Air enters the inner cavity of the outer barrel 13 from the air inlet 11 under the action of the air inlet fan, and flows around the strong magnetic oxygen-nitrogen separator 5 through the airflow channel 12, oxygen in the air is attracted to the gathering area on the peripheral surface of the permanent magnet 6 by magnetic force, the oxygen is gathered continuously under the action of a gradient magnetic field of the gathering area, and at the moment, under the action of the high-pressure exhaust fan, oxygen-enriched air is extracted from the gathering area through the oxygen-enriched gathering channel 17, the gap channel 16-1, the gathering hole 9-1 and the oxygen-enriched air outlet 19, so that the whole working process is completed. Because the separated oxygen-enriched air is extracted from the gap 16-1 on the oxygen-enriched channel gap supporting piece 16 between the two poles of the permanent magnet 6, the separated oxygen is effectively prevented from being mixed with the nitrogen again due to the influence of turbulence, and the concentration of the oxygen-enriched air is further improved.
