Description

The molecular sieve formula oxygenerator of the outer interface tube of band

The utility model relates to and a kind ofly is used to keep healthy or the outer exhaust port of molecular sieve formula oxygenerator, especially its band of first aid or the casing of air inlet pipe interface.

The structure of existing molecular sieve formula oxygenerator can be seen from Fig. 7, it contains the casing 14 of a band air intlet 15, oxygen outlet 9, nitrogen outlet 10, is installed in air cleaner 1, air compressor machine 4, cooling tube 5, left molecular sieve 13, right molecular sieve 11, oxygen tank 12, left valve 2, right valve 3, pressure regulator valve 6, biofilter 7, flowmeter 8 in the casing.Air enters oxygenerator by import 15, process filter 1 boosts in air compressor machine 4, cooling tube 5 coolings, left and

right valve

2,3 by the time-delay alternation is controlled in the left and right molecular sieve 13,11 and screens out nitrogen then, enter oxygen tank 12 at last, export from oxygen outlet 9 through pressure regulator valve 6, biofilter 7 and flowmeter 8 again.Left and right molecular sieve is in the oxygenerator course of work, an one molecular sieve screens compressed air, removing nitrogen, and washes away nitrogen on the sieve with oxygen in another molecular sieve, this nitrogen is drawn from left and right valve, and is outwards discharged by the nitrogen outlet on the casing 10.The shortcoming of existing this molecular sieve formula oxygenerator is: nitrogen directly enters indoor from casing, it pollutes the environment around the oxygenerator, harm people around's health, and also have influence on the air inlet quality of oxygenerator itself, nitrogen content in the air inlet is improved, so fallen the prepared oxygen purity of oxygenerator.

The purpose of this utility model is to overcome the shortcoming that exists in the above-mentioned prior art, the molecular sieve formula oxygenerator of the outer interface tube of band that a kind of oxygen purity height that it makes and oxygen preparation do not pollute surrounding environment is provided, and makes it have simple in structure, manufacturing and characteristics such as easy to use.

The molecular sieve formula oxygenerator of the outer interface tube of the utility model band contains the casing of a band air intlet, oxygen outlet, nitrogen outlet and is installed in casing interior air cleaner, air compressor machine, cooling tube, left molecular sieve, right molecular sieve, oxygen tank, left valve, right valve, pressure regulator valve, biofilter, flowmeter, its feature is: casing is interface tube outside air intlet and nitrogen outlet position place has respectively, this interface be one with the outer tube joint of casing with removable connection.

Outer tube joint in the utility model molecular sieve formula oxygenerator be one with the gas thread formula joint of casing to be threaded, or internal thread flange fitting that is connected with screw with casing, also can be one with the housing type joint of casing to be threaded, or one with casing with screw flange connecting housing type joint.

The utility model molecular sieve formula oxygenerator can also connect a silencer at the medial extremity of joint.

The utility model has the advantages that: 1) be provided with on casing after the outer interface tube of can conveniently peg graft rubber tube or plastic tube, molecular sieve formula oxygenerator can not pollute room air and guarantee the purity of prepared oxygen in oxygen preparation; In addition, on the inlet and outlet mouth, silencer has been installed, can have been reduced noise again, so it can be used for confined chamber especially, as air-conditioned room, and first aid place such as hospital, ambulance; 2) easy to operate and its good leak tightness of the intubate of outer interface tube; 3) manufacturing of outer tube joint, easy for installation and it does not influence complete machine structure.

To and contrast accompanying drawing by embodiment below, the utility model will be further described below, have in the accompanying drawing:

Fig. 1 is that the structural representation of the molecular sieve formula oxygenerator of the outer interface tube of the utility model band is always schemed;

Fig. 2, Fig. 3, Fig. 4 and Fig. 5 are respectively the structure charts of four kinds of embodiments of the outer interface tube on the casing in the utility model molecular sieve formula oxygenerator;

Fig. 6 is the structure positive view of the silencer 17 among Fig. 1;

Fig. 7 is that the structural representation of existing molecular sieve formula oxygenerator is always schemed.

From Fig. 1, see the structure of this real novel molecular sieve formula oxygenerator, it contains the casing 14 of band air intlet 15, oxygen outlet 9 and a nitrogen outlet 10, be installed in the air cleaner 1 with airtight pipeline connection, air compressor machine 4, cooling tube 5, left molecular sieve 13, right molecular sieve 11, oxygen tank 12, left valve 2, right valve 3, pressure regulator valve 6, biofilter 7 and flowmeter 8 in the casing, casing 14 is interface tube 16 outside air intlet and place, nitrogen outlet position have respectively.

Outer interface tube 16 in the utility model molecular sieve formula oxygenerator be one with casing outer tube joint with removable connection.Fig. 2～Fig. 5 is respectively the structure chart of four embodiment of removable outer tube joint, joint 16 wherein shown in Figure 2 be one with the gas thread formula joint of casing 14 to be threaded, the outboard end of this joint is sleeve or with the outer tube that is threaded directly; Joint among Fig. 3 is an internal thread flange fitting that is connected with screw with casing, and outer tube can be threaded in the inner bolt hole of flange; Joint among Fig. 4 be one with the housing type joint of casing to be threaded, direct sleeve plastic tube (representing outer tube with double dot dash line among Fig. 4) on this joint; Joint among Fig. 5 be one with casing with screw flange connecting housing type joint, among the figure with the outer tube of biobelt line expression plastics or rubber system, this outer tube directly sleeve to joint.Be connected on the joint outer tube, its in addition end can in use place outside window the nitrogen that produces with the discharging oxygen preparation or import fresh air to oxygenerator from outdoor.
