Description

Technical Field

[0001] The utility model relates to the relevant field of oxygen generator adsorption towers, and more specifically, to an upper cover installation mechanism for an industrial oxygen generator adsorption tower. Background Art

[0002] The industrial oxygen generator separates air mainly by two adsorption towers filled with molecular sieves. Under normal temperature conditions, the compressed air is filtered, dehydrated, dried and purified before entering the adsorption tower. In the adsorption tower, nitrogen and other gases in the air are adsorbed by the molecular sieves, and oxygen is enriched in the gas phase. It flows out from the outlet and is stored in the oxygen buffer tank. In the other tower, the molecular sieve that has completed the adsorption is rapidly depressurized to analyze the adsorbed components. The two towers are circulated alternately to obtain cheap oxygen with a purity of ≥90%.

The operation is time-consuming and labor-intensive, and is not conducive to improving assembly efficiency. Utility Model Content

The upper end of the fixed seat 7 is rotatably connected to the movable sleeve 8 through a bearing 701. The upper end of the movable telescopic rod 10 is rotatably connected to the inner wall of the embedding groove 9 through a connecting rod 1001. A rubber anti-slip sleeve 1003 is arranged on the outer end surface of the movable telescopic rod 10. The upper end of the oxygen concentrator adsorption tower 1 is also provided with a limiting hole 1002 that is clamped to the bottom of the movable telescopic rod 10.

[0024] Based on the above structure, when the upper cover body 3 of the device is disassembled, the staff pulls the movable telescopic rod 10 upward to disengage its outer end from the limiting hole 1002 at the upper end of the oxygen generator adsorption tower 1, and then adjusts the angle of the movable telescopic rod 10 by rotating the connecting rod 1001 and makes it perpendicular to the outer side of the movable sleeve 8 (it should be noted that the maximum adjustment angle range of the movable telescopic rod 10 is 90°). After the adjustment is completed, the movable telescopic rod 10 is stretched and the length is stretched to act as a "handle" structure.
