Description
Technical field
The utility model relates to a kind of small-sized absorption tower that is used for oxygen preparation, more particularly, relates to adopt push-in structure design between oxygen container and the adsorber of absorbent module in a kind of oxygen preparation facilities that utilizes transformation absorption (PSA) system oxygen principle design.
Background technology
In recent years, along with growth in the living standard, people's health care consciousness is more strong, and especially oxygen therapy is progressively accepted by general family, and oxygenerator forward normal domestic use electric type product changes, and becomes general household electrical appliances at home.Owing to use the oxygen crowd to be mostly weak crowds such as old man, patient, therefore, the miniaturized of oxygenerator, portable increasing demand are strong.The small portable oxygenerator is the oxygenerator main development tendency.Adsorption tower is the core component of PSA molecular sieve oxygen generation.The PSA oxygenerating technology be at air when the adsorption tower of sorbent materials such as molecular sieve is housed; Utilize under the different pressures condition molecular sieve to oxygen, nitrogen molecule different adsorption characteristic; Under pressurized conditions, accomplish the adsorption separation process of nitrogen oxygen; The nitrogen that depressurization desorption is adsorbed, thus realize the purpose that nitrogen oxygen separates and sorbent circulation is used.Because adsorption tower is designed with inlet mouth, oxygen exhaust, denitrogen mouth; Linking to each other of realization and air compressor machine, oxygen container, denitrogen tube; Therefore; The structure design of adsorption tower, mode of connection have also restricted the volume size of oxygenerator except that oxygen yield, oxygen concn, the stability to oxygenerator plays the crucial effects, are the core cells of portable PSA oxygenerator.
Present already present oxygenerator adsorption tower design principal mode is following:
Adsorption tower separates with gas distributing valve, oxygen container, sound damper etc., connects through flexible pipe, fast insert etc.This type of design belongs to oxygenerator early stage of development product, and component are numerous, connects in a jumble less at present employing.
Secondly, there also have part producer that adsorption tower top and gas distributing valve are adopted to be push-in integrated, connects the oxygen flexible pipe bottom the adsorption tower; A hose connection three-way interface; Three-way interface one end and another adsorption tower three-way interface form flushing pipeline through hose connection, in the middle part of flushing flexible pipe a copper cylinder are housed; Be equipped with a small through hole in the middle of the copper post, form flushing port.The three-way interface the other end connects vacuum breaker, and the other end of vacuum breaker forms whole adsorption tower through the three-way interface laggard oxygen container that confluxes.Adsorption tower top and gas distributing valve adopt the push-in integrated tie point that reduced in this design, the plugging mode effective and rapid, but, make the adsorption tower overall volume limited by vacuum breaker owing to vacuum breaker need externally carry out hose connectionly; Simultaneously, hose connection contact is many, seems mixed and disorderly, not attractive in appearance.
In addition, also have the adsorption tower of upper and lower two modular structures, between upper and lower module, assemble the integrated adsorption tower of molecular sieve adsorber, oxygen container and denitrogen tube.Chinese patent 200720171174.X discloses a kind of medical oxygen producing machine technology; Adsorption tower in this technology adopts upper and lower two modules; Between upper and lower module, assemble molecular sieve adsorber, air tank and denitrogen tube, medical molecular sieve is housed in the molecular sieve adsorber.Compressed air inlet pipe and nitrogen vent pipe are arranged above upper module, and the top of the right and left of these two pipes is equipped with an electromagnetic switch valve module respectively.The inlet mouth of this assembly joins with compressed air inlet pipe respectively, and its air outlet joins with molecular sieve adsorber and denitrogen tube respectively.Relief valve also is equipped with in the top of air tank.Below lower module, be designed with two oxygen hoses that communicate with the bottom of air tank respectively, between two oxygen hoses a throttling pore arranged, two vacuum breakers are housed on the lower module of air tank lower end, each vacuum breaker joins with an oxygen hose respectively.Air tank and denitrogen tube and height such as adsorber grade during this method design; Rely on up and down module and bolt extruding mode of connection to be fixed on up and down in the middle of the module; Cause system during oxygen air tank too high, air in the tube, replacement of oxygen time are long, can not after start, obtain high-concentration oxygen in the short period of time; The mode of module and bolt extruding mode of connection caused two towers to fill imbalance easily about oxygen container and denitrogen tube relied on simultaneously after the vibrations, influence system oxygen effect.And the standing bolt of module keeps in repair about needing during maintenance to remove fully, can't realize the maintenance of single suction adnexa, change.
