Description

TECHNICAL FIELD

[0001] The utility model relates to the field of oxygen generator adsorption tower, especially to a molecular sieve oxygen generator adsorption tower. BACKGROUND

[0002] The main components of air are nitrogen (accounting for 78%) and oxygen (accounting for 21%), so air can be said to be an inexhaustible source for preparing nitrogen and oxygen. At present, an oxygen generator uses molecular sieve physical adsorption and desorption technology, and an industrial oxygen generator separates air mainly by two adsorption towers filled with molecular sieve. Under normal temperature conditions, compressed air is purified by filtration, water removal and drying, and then enters the adsorption tower. In the adsorption tower, nitrogen in the air is adsorbed by the molecular sieve, and oxygen is enriched in the gas phase, flows out of the outlet and is stored in an oxygen buffer tank. The molecular sieve in the other tower that has completed adsorption is rapidly depressurized to desorb the adsorbed components. The two towers are alternately circulated, so that inexpensive oxygen with a purity of ≥ 90% can be obtained.

[0003] When adding molecular sieve into the existing barrel, artificial knocking on the outer wall of the barrel is needed to make the gap between the molecular sieves minimum, so as to ensure that the friction between the molecular sieve particles is minimum after manual compression to ensure work efficiency. This not only wastes time and effort, but also affects efficiency.

[0004] The prior art 202420522368.3 discloses a molecular sieve adsorption tower compaction device for an oxygen generator. Although manual compression is not needed, the distribution of the molecular sieve inside is uneven during compression, most of the molecular sieve is accumulated in the middle, thereby affecting the adsorption effect, and the molecular sieve is not convenient to replace when replaced.
