Oxygen making machine used molecular sieve adsorption column

Abstract

The invention discloses an oxygen making machine used molecular sieve adsorption column which comprises a cylinder body and a molecular sieve, wherein an air flow equalization board is arranged in the cylinder body; the molecular sieve is arranged in a cavity formed between the air flow equalization board and the end surface of an air outlet end; a reserved space is formed between the air flow equalization board and the end surface of the air outlet end; a spring is arranged in the reserved space; an air inlet is formed in the side surface of an air inlet end. Compared with the prior art, the adsorption column has the advantages that the pulverization of the molecular sieve is prevented, the molecular sieve can be replaced quickly, and the high convenience and practicality are achieved.

Description

technical field [0001] The invention relates to the technical field of medical oxygen production, in particular to a molecular sieve adsorption tower for an oxygen generator that prevents molecular sieve pulverization. Background technique [0002] Molecular sieve pulverization is one of the important factors that seriously affect the life of the oxygen generator. In the prior art, when the molecular sieve begins to pulverize, the size of the pulverized molecular sieve becomes smaller after pulverization, and the fluidity of the molecular sieve in the space will decrease. Increase, after the flow increases, the surrounding molecular sieve particles are washed by the air flow, which increases the friction between the particles, resulting in the pulverization of more adsorbent particles. This chain reaction will seriously affect the service life of the molecular sieve. At the same time, after the molecular sieve is pulverized, It is easy to crystallize. When replacing the mole...

[0002] Molecular sieve pulverization is one of the important factors that seriously affect the life of the oxygen generator. In the prior art, when the molecular sieve begins to pulverize, the size of the pulverized molecular sieve becomes smaller after pulverization, and the fluidity of the molecular sieve in the space will decrease. Increase, after the flow increases, the surrounding molecular sieve particles are washed by the air flow, which increases the friction between the particles, resulting in the pulverization of more adsorbent particles. This chain reaction will seriously affect the service life of the molecular sieve. At the same time, after the molecular sieve is pulverized, Easy to crystallize, when replacing the molecular sieve, the molecular sieve is not easy to take out, maintenance is troublesome, and the maintenance cost is increased
