Abstract
The utility model discloses a pressure-holding stabilizing device of a molecular sieve in an adsorption tower of a medical oxygen generator, which comprises a molecular sieve isolation device which is arranged in a tower neck at the top of the adsorption tower in a sliding mode, is pressed on the upper surface of the molecular sieve and can permeate gas, wherein the upper surface of the molecular sieve isolation device is provided with a spring in a pressing mode, the upper end of the spring is fixedly connected with an airflow split baffle, the diameter of the airflow split baffle is smaller than the diameter of the inner wall of the tower neck, and the airflow split baffle is connected with a flange at the top of the adsorption tower via a support fixedly arranged on the upper surface of the baffle. The utility model has the technical scheme that the spring is used for fastening the molecular sieve via the molecular sieve isolation device, and when the molecular sieve sinks, the spring pushes the molecular sieve isolation device to continue to compact the molecular sieve; and the upper end of the spring is provided with the airflow split baffle which can split high-pressure gas blown down from the top of the adsorption tower to the periphery, then the gas flows downwards uniformly to make the spring uniformly stressed up and down, and inwards and outwards, and the stability is improved. The molecular sieve is ensured to be free from the promotion of airflow pressure, and the service life of the modular sieve is prolonged.
Description
Technical field
The utility model relates to a kind of medical oxygen generator, especially the pressurize stabilising arrangement of molecular sieve in the adsorption tower of medical oxygen generator.
Background technology
Normal temperature transformation medical oxygen generator mainly is a transformation absorption principle of using molecular sieve, and cleaned air passes is carried out O
2, N
2Separate.When air entered molecular sieve, molecular sieve was subjected to the washing away of gases at high pressure of periodically pulsing, was in alternation wriggling state all the time.The wriggling of molecular sieve will acceleration molecular the efflorescence of sieve, thereby the performance and the service life of reducing molecular sieve therefore must compress molecular sieve.The existing mode that compresses molecular sieve in the adsorption tower mainly contains following two kinds: the one, and the leading screw fastening, this method is the bottom of adsorption tower of earlier molecular sieve being packed into, after installing to the tower neck position on adsorption tower top, place the molecular sieve spacer assembly at the molecular sieve upper surface, between molecular sieve spacer assembly and adsorption tower top flange, add a strong point, rely on the strong point to compress the molecular sieve spacer assembly with leading screw then, fastening molecular sieve, the defective of this leading screw fastening is, in case molecular sieve sinks, compressing leading screw can not dynamically follow up, the molecular sieve decompression; The 2nd, the cylinder fastening, be to fix a cylinder in the adsorption tower outer tip end, then cylinder piston rod is goed deep into tower body, compress the molecular sieve spacer assembly, the defective of this cylinder fastening is, being difficult to accomplish is not having oil, keep the sealing of cylinder piston rod and tank body in the motion, gas leak phenomenon takes place easily, secondly, also because the cylinder piston throw of lever is very short, along with the continuous sinking of molecular sieve, in case reach extreme limit of travel, molecular sieve will be because of continuing the decompression of sinking, once more, the motive force of cylinder is taken from the oxygenerator itself that pressure constantly changes at 0～0.8Mpa, and the active force instability that this just causes cylinder itself finally causes the molecular sieve pressure transient.
The utility model content
The purpose of this utility model is: provide the pressurize stabilising arrangement of molecular sieve in a kind of medical oxygen generator adsorption tower, the molecular sieve of can stablize, reliable fastening oxygenerator adsorption tower is interior.
For achieving the above object, the utility model can be taked following technical proposals:
The pressurize stabilising arrangement of molecular sieve in the utility model medical oxygen generator adsorption tower, comprise and be slidingly arranged in molecular sieve spacer assembly in the adsorption tower top drum neck, that be pressed in the molecular sieve upper surface, can penetrating gas, pressure is provided with a spring on described molecular sieve spacer assembly, the upper end of this spring and an air-flow divide baffle plate affixed, and described air-flow divides the diameter of baffle plate to be connected with the top flange of described adsorption tower less than the diameter of described tower neck inwall and by the support that is installed in its upper surface.
Passage and its center that described air-flow divides the periphery of baffle plate to be provided with a plurality of symmetries are provided with a fabrication hole.
Technique scheme also comprises a part sieve spacer assembly guide collar, this molecular sieve spacer assembly guide collar and described tower neck inwall be slidingly matched and its lower end and described molecular sieve spacer assembly affixed, described air-flow divides the diameter of the diameter of baffle plate less than described molecular sieve spacer assembly guide collar inwall; Described molecular sieve spacer assembly is made of two-layer double-edged fine-toothed comb and the molecular sieve filter screen that is clipped in described two-layer double-edged fine-toothed comb centre.
The technical solution of the utility model adopts spring to come fastening molecular sieve through the molecular sieve spacer assembly, and when molecular sieve sank, spring promoted the molecular sieve spacer assembly and continues to compress molecular sieve; Because air-flow is walked sometimes from top to bottom, sometimes walk from the bottom up, when walking from top to bottom, have the rapid expansion of air-flow, meeting disturbance spring is provided with air-flow in the upper end of spring and divides baffle plate, the shunting all around that the gases at high pressure of blowing down from the adsorption tower top can be divided baffle plate to described air-flow, just evenly flow downward then, make about the spring, inside and outside stressed evenly, stability improves.As seen, the utility model can guarantee that molecular sieve is not urged by stream pressure, prolongs the service life of molecular sieve.
