Molecular sieve oxygenerator and molecular sieve device thereof

Abstract

The invention relates to a molecular sieve device which comprises a cylindrical molecular sieve cover with an opening in one end, a mounting structure is arranged at the opening end of the molecular sieve cover, an adapter plate is arranged on the outer side of the bottom of a molecular sieve cover barrel, the adapter plate is fixedly connected with the molecular sieve cover, a molecular sieve module is arranged in the molecular sieve cover barrel, and the molecular sieve module is detachably connected with the molecular sieve cover; the molecular sieve module penetrates through the molecularsieve cover to be tightly connected with the adapter plate, and a sealing rubber sleeve is arranged at the joint of the adapter plate and the molecular sieve cover. The invention further relates to amolecular sieve oxygenerator which comprises a controller, a compressor, an electromagnetic valve, a shell and a molecular sieve device, wherein a dismounting opening is formed in the shell, a cavityfor installing the molecular sieve device is arranged in the dismounting opening, and the molecular sieve device is arranged in the cavity. The molecular sieve module is designed into a whole and is in sliding connection with the molecular sieve cover, after the molecular sieve module loses efficacy, only the molecular sieve module needs to be pulled out of the molecular sieve cover to be replaced, and the problems that the molecular sieve system is difficult to replace and is high in direct rejection cost are solved.

Description

technical field [0001] The invention relates to the field of oxygen generators, in particular to a molecular sieve oxygen generator and a molecular sieve device thereof. Background technique [0002] Molecular sieve oxygen generator adopts pressure swing adsorption oxygen production technology, and adopts high-pressure adsorption and low-pressure desorption by using zeolite molecular sieve to increase the gas adsorption capacity with the increase of gas pressure and the different adsorption characteristics of nitrogen and oxygen adsorption capacity under the same gas pressure. The cyclic process separates oxygen from the air. It can be known from the working principle that the molecular sieve system is a key component of the oxygen generator. The current molecular sieve oxygen generator products have good performance in terms of oxygen concentration stability and quietness, but there is little research on the modular design of the molecular sieve system. In general, the se...
