Description
Technical Field

Background
The PSA oxygen generator uses zeolite molecular sieve as adsorbent, and utilizes pressure adsorption to reduce pressureThe principle of pressure desorption adsorbs and releases oxygen from air, thereby separating oxygen. The zeolite molecular sieve is a white spherical granular adsorbent whose surface and interior are fully distributed with micropores. Its pore characteristics enable it to implement O2、N2The kinetic separation of (3). Zeolite molecular sieve pair O2、N2The separation of (A) is based on a slight difference in the kinetic diameters of the two gases, N2The molecule has faster diffusion rate in the micropores of the zeolite molecular sieve, O2The molecular diffusion rate is slow. Compressing water and CO in air2Does not differ much from nitrogen. The final enrichment from the adsorption column is the oxygen molecules. The pressure swing adsorption oxygen production utilizes the selective adsorption characteristic of zeolite molecular sieve, adopts the cycle period of pressure adsorption and pressure reduction desorption to make compressed air alternatively enter into adsorption tower to implement air separation so as to continuously produce high-purity product oxygen. The industrial oxygen generator is based on pressure swing adsorption principle and adopts high-quality zeolite molecular sieve as adsorbent to produce oxygen from air under a certain pressure.
The molecular sieve bed is a cylinder filled with molecular sieve, and is one of the key components in the PSA oxygen generator. In the prior art, a conventional molecular sieve bed is designed into a single cylinder structure, and two molecular sieve beds are arranged in an oxygenerator to realize double-tower PSA (pressure swing adsorption) circulation. For such a split molecular sieve bed, the molecular sieve raw material barrel is usually lifted to a certain height in the molecular sieve filling process, the molecular sieve is firstly poured into a hopper of a filling machine, a screw structure at an outlet of the hopper rotates at a certain rotating speed within a set time, and the molecular sieve freely falls after passing through a screw gap and is filled into a molecular sieve barrel.
The prior art has the following defects:
(1) during rotation of the screw, some of the molecular sieve particles may be crushed to produce dust. The dust can enter the control valve during the operation of the oxygen generator, so that the flow control of the oxygen generator is abnormal.

(3) After the molecular sieve is filled, the height of the center of the cylinder is high, the periphery of the cylinder is low, and the phenomenon of uneven height appears. The sieve needs to be vibrated down by a vibrating table, and dust can be generated due to high-frequency friction among the molecular sieve particles during vibration. If the frequency and amplitude of the tap are not proper, the tightness of the molecular sieve is inconsistent, the uniformity of gas circulation is affected, and the gas separation efficiency is reduced.
(4) After the two molecular sieve beds with obvious difference in filling conditions are installed in one oxygen generator, the concentration, flow and pressure of oxygen produced by the two molecular sieve beds are different due to the obvious difference of gas separation efficiency. Finally, the concentration, the flow and the pressure of the oxygen output by the oxygen generator have large fluctuation.
