Description of drawings
The Figure of description that constitutes the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:
Fig. 1 has schematically shown the cutaway view according to the embodiment of molecule screen drum of the present utility model; And
Fig. 2 shows the partial enlarged view at A place among Fig. 1.
The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
In conjunction with referring to Fig. 1 and Fig. 2, Fig. 1 shows the cutaway view according to the preferred embodiment of molecule screen drum of the present utility model, as can be seen from Figure 1, the molecule screen drum of present embodiment comprises cylindrical shell 10, bottom end cover 31, upper end cover 32, has inlet channel 311 on the bottom end cover 31, have outlet passageway on the upper end cover 32, the air admission hole of inlet channel 311 is arranged on the sidewall of bottom end cover 31.In the present embodiment, the bottom end cover 31 of molecule screen drum, upper end cover 32 all are spirally connected with cylindrical shell 10.
Molecule screen drum in the present embodiment, the air admission hole of inlet channel 311 is arranged on the sidewall of bottom end cover 31, when entering molecular sieve, Compressed Gas at first enters inlet channel 311 by air admission hole, Compressed Gas upwards flows after turning over certain angle, like this, gas is alleviated greatly to the impulsive force of molecular sieve, the molecular sieve adsorption effect is strengthened, and improve the service life of molecular sieve.
Preferably, inlet channel 311 is bending shape, comprises the horizontally disposed first inlet channel 311a and from the inboard vertically upwardly extending second inlet channel 311b of the first inlet channel 311a; The air admission hole of formation with one voice of the sidewall of the first inlet channel 311a and bottom end cover 31.Like this, need turn over 90 degree backs when Compressed Gas enters molecule screen drum 10 and upwards flow, make and alleviate the best results of gas the molecular sieve impulsive force.
Preferably, the big up and small down structure in the upper end of the second inlet channel 311b.As can be seen from Figure 2, the upper end of the second inlet channel 311b of present embodiment is infundibulate.The process certain angle was domatic when infundibulate rose Compressed Gas, gas velocity is further relaxed, and make Compressed Gas be transformed into the flow regime that is covered with the screen drum cross section, thereby effectively avoided pouring fast the huge impulse force of the gas of molecule screen drum the molecular sieve generation by initial collected state.Compressed Gas fully contacts with the molecular sieve of bottom uniformly, and it is more abundant that molecular sieve is got gas absorption.
Preferably, the molecule screen drum of present embodiment also comprises: be arranged on first filter core 51 and second filter core 52 in the molecule cylindrical shell 10; First filter core 51 is arranged near bottom end cover 31 places, and second filter core 52 is arranged near upper end cover 32 places.Compressed Gas enters from inlet channel 311, by the filtration of first filter core 51, contacts with molecular sieve and adsorbs earlier.Between second filter core 52 and upper end cover 32, also be provided with elastic shock attenuation mechanism, for compression spring 90, be used for damping in the present embodiment, compress molecular sieve thereby compress second filter core 52 when making Compressed Gas impact molecular sieve, avoid the strenuous vibration of molecular sieve, prolonged service life.In addition, preferably, first filter core 51 and second filter core 52 include sieve plate and nonwoven, as shown in Figure 2, are example with first filter core 51, comprise be positioned at the below sieve plate 511 and be positioned at the top nonwoven 512; Second filter core 52 and first filter core 51 are provided with accordingly, and promptly the sieve plate of second filter core 52 is arranged on the nonwoven top.This structure had both guaranteed enough ventilation spaces, stopped effectively that again molecular sieve does not enter gas circuit, avoided stopping up gas circuit and impacted going out oxygen.The material of sieve plate 511 is preferably polyoxygenated polyformaldehyde (POM), and material is more stable, and is not yielding.
Preferably, as shown in Figure 1, between the sieve plate 511 of first filter core 51 and cylindrical shell 10, be provided with first sealing ring 71, help the sealing between sieve plate 511 and the cylindrical shell 10 on the one hand, 71 swellings of first sealing ring have been avoided under the impact of air-flow in the annular groove of sieve plate 511 so on the other hand, relative motion takes place with cylindrical shell 10 in sieve plate 511, cause the strenuous exercise of molecular sieve, perhaps sieve plate becomes flexible, tilts to produce the problem of leaking sieve, thus the service life of prolongation molecular sieve.Second sealing ring 72 is arranged between the sieve plate and cylindrical shell 10 of second filter core 52, acts on identical with the effect of first filter core 51.In addition,, help the sealing of molecule screen drum, and then help guaranteeing the oxygen generation concentration of oxygenerator being equipped with sealing ring between cylindrical shell 10 and the bottom end cover 31 and between cylindrical shell 10 and upper end cover 32.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
The molecule screen drum of present embodiment, effectively overcome Compressed Gas and entered the molecule screen drum fast, molecular sieve is impacted, cause molecular sieve to increase the problem that reduces with distance along air inlet adsorption efficiency radially, effectively improved the adsorption efficiency of molecular sieve, thereby improved the oxygen generation efficiency and the oxygen generation concentration of oxygenerator gas.The material selection polyoxygenated polyformaldehyde (POM) of sieve plate adopts the sealing ring sealing simultaneously, has prevented effectively because sieve plate becomes flexible the leakage sieve that tilts to produce, the problem that oxygen generation efficiency reduces.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
