Description

Technical Field

[0001] The utility model relates to the technical field of molecular sieve oxygen generators, in particular to a molecular sieve adsorption structure. Background Art

[0002] The molecular sieve oxygen generator uses air as raw material. The air is pressurized, purified, dried, and cooled, and then poured into the adsorption structure of the molecular sieve. The adsorption structure in the molecular sieve adsorbs nitrogen, carbon dioxide, etc. in the air, and the gas flowing out is high-purity oxygen. When the molecular sieve oxygen generator is running to produce oxygen from the air, the adsorption structure in the molecular sieve is a consumable and needs to be replaced frequently.

[0003] When implementing this technical solution, there are at least the following defects: although the existing molecular sieve can be adsorbed, it is often not convenient to quickly disassemble and remove it in the oxygen generator housing, which affects the efficiency of molecular sieve replacement by the staff and thus affects the working efficiency of the oxygen generator. Therefore, we propose a molecular sieve adsorption structure. Utility Model Content

[0007] Optionally, a rubber baffle is fixedly mounted on the upper end of the inner cavity of the shell, and the lower end of the rubber baffle is in contact with the upper end of the other side of the molecular sieve adsorption frame.

[0008] By adopting the above technical solution, it is convenient to set up the rubber baffle to block the incoming gas and ensure that all the gas passes through the molecular sieve adsorption frame.

[0009] Optionally, a spring is sleeved on the outer wall of the positioning rod, and one end of the spring is fixedly connected to the outer side of the shell.

[0010] By adopting the above technical solution, it is convenient to drive the positioning rod to reset through the setting of the spring.

[0011] Optionally, the sphere is arranged above the wedge-shaped block, and the sphere fits the inclined surface of the wedge-shaped block.

[0012] By adopting the above technical solution, the spherical body and the wedge block cooperate with each other, so that the positioning rod can be pushed in a linked manner during the movement of the fixing frame.

[0013] Optionally, one end of the positioning rod movably passes through the middle of the other side of the shell.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] The technical solution of the present application, through the provision of a shell, a molecular sieve adsorption frame, a rubber cover, a fixing rod, a sphere, a spring and a rubber baffle, can not only enable the fixing frame to drive the rubber cover to follow the movement, so that the rubber cover is separated from the outlet, thereby facilitating the removal of the disassembled molecular sieve adsorption frame, but also can enable the fixing frame to drive the fixing rod to follow the movement during the upward movement of the fixing frame, and the fixing rod drives the sphere to separate from the wedge block, and then, relying on the resilience of the spring, the spring drives the positioning rod to separate from the molecular sieve adsorption frame, further facilitating the separation of the shell from the molecular sieve adsorption frame, thereby facilitating the removal of the molecular sieve adsorption frame for replacement, and further ensuring the working efficiency of the oxygen generator.
