Grade handles nitrogen and oxygen moment, and specifically including at least one and ejector pipe 1, " ' is in the channel of same axis, respectively
The outlet that channel is all had the entrance for air accumulation and flowed out for air with layer flow mode, neighbouring " the ' entrance of ejector pipe 1
Channel outlet be greater than ejector pipe 1 " ' air intake end 11 " ' outer diameter, in order to realize equipment for magnetic separation 3 " magnetic field gradient of ',
Turbulent flow is formed in order to prevent simultaneously, and the oxygen after level-one is enriched with need to be made into concurrent flow and enter next stage to be enriched with again, and each item is logical
Road is made of the magnetic patch of a pair of fixed cyclization, and at neighbouring air intake end 11, " position of ' has flat segments to the inner wall of each pair of magnetic patch
21 " ', in separate air intake end 11 " position of ' has converging transition 22 " ', and " thickness of ' more approaches flat segments to the converging transition 22
21 " ' is thicker.
In the present embodiment, more easily, description is unfolded so that single-stage is enriched with as an example.
Each pair of magnetic patch of oxygen-enriching device 2 is be located at ejector pipe 1 " ' axis two sides and opposite polarity first magnetic patch
211 " ' and the second magnetic patch 212 " ', 211 " ' and the second magnetic patch 212 " ' of the first magnetic patch pass through fastener 4, and " ' is fixed cyclic.For convenience
First magnetic patch 211 " ' and the second magnetic patch 212 " ' is fixed, " ' setting that 211 " ' and the second magnetic patch 212 " ' of the first magnetic patch passes through bracket 6
In the upstream of ejector pipe 1 " ' air intake end 11 " ', " ' is U-shaped, and wherein bracket 6 " two transverse arms 61 of ' " ' is connected to and draws for bracket 6
The tube wall periphery of pipe 1 is penetrated, is provided on bracket 6 " the vertical arm 62 of the two of ' " ' and fastener 4 " through-hole 321 of ' cooperation " '.Wherein, tightly
" ' includes by being in the first hoop 41 of half arc " ' and the second hoop 42 " ', which is connected to each other, to be formed, the first hoop 41 " ' of firmware 4 and
Second hoop, 42 " both ends of ' are outward extended with first lug 411 " ' and the second lug 412 " ', and first lug 411 " ' and
Second lug 412 " is provided with threaded hole, is connected to the spiral shell after limited screw 413 " ' is thread through a through-hole 321 " ' between '
In pit, and its head is stuck in outside first lug 411 " ' or the second lug 412 " '.In order to realize escape pipe 5, " ' not only has spray
Combustion gas is penetrated, also has the function of separating oxygen and nitrogen in air, bracket 6 " a wherein vertical arm 62 of ' " ' is in 321 " ' of through-hole
Front end be provided with nozzle carrier and nozzle and with the mutually a sequence of escape pipe 5 of spout " ', the escape pipe 5 " ' of nozzle towards injection
The air intake end 11 of pipe 1 is " in '.Preferably, " ' is L-shaped, and " vertical portion of ' is made escape pipe 5 of paramagnetic material, wears for escape pipe 5
After crossing the axle center of 211 " ' and the second magnetic patch 212 " ' of the first magnetic patch formation ring, towards in ejector pipe 1 " the air intake end 11 of ' " '.When
So, the air intake end 11 of escape pipe 5 " ejector pipe 1 can be also arranged in the vertical portion of ' " ' is " outside '.And escape pipe 5 " ' separation of nitrogen and
The separation rate of oxygen depends on escape pipe 5, and " the caliber curvature of ', caliber is bigger, and curvature is smaller, the separation of separation of nitrogen and oxygen
Rate is with regard to smaller, for this purpose, the outer diameter of the vertical portion of escape pipe 5 is preferably 1~10mm, when air is entering " the ' air intake of ejector pipe 1
" before ', escape pipe 5 " ' and oxygen-enriching device 2 " ' has first carried out the pre-separation of oxygen and nitrogen in air, then through magnetic separation at end 11
Nitrogen and oxygen out, since " ' is fixed into for " the first magnetic patch 211 of the ' " ' of oxygen-enriching device 2 and the second magnetic patch 212 in the present embodiment
Ring outer diameter is greater than the outer diameter of ejector pipe 1 " ' air intake end 11 " ', in this way, what 211 " ' and the second magnetic patch 212 " ' of the first magnetic patch was formed
Ring and ejector pipe 1 " ' air intake end 11 " two sides ' all have gap, when having certain oxygen-enriched air to enter magnetic with certain flow rate
" after ', nitrogen passes through above-mentioned gap and is discharged power separator 3, and it is corresponding to stay in ejector pipe 1 " ' is in air intake end 11 " ' in this way
Air between tube wall is exactly the opposite higher oxygen-enriched air of oxygen content.
Certainly, " ' also can be set in 2 ' of equipment for magnetic separation in example 2 the oxygen-enriching device 2, equally also in sky
On the direction of flow of air, it is located at " the upstream of ' of equipment for magnetic separation 3.
