Problems solved by technology

The disadvantage of the existing technology is that the flow process of the gas during desorption is too long, and the entry and exit are limited to the air inlet and exhaust port of the cylinder, resulting in too long time for the desorption process

Abstract

The invention discloses an oxygen preparation device. The oxygen preparation device comprises a filtering mechanism, an air compressor, a temperature and humidity adjusting mechanism and an oxygenation mechanism which are sequentially connected via air pipelines, wherein the oxygenation mechanism comprises two parallel molecular sieve columns and a sealing casing; the two molecular sieve columns are arranged in the sealing casing in parallel, and the molecular sieve columns is connected with a desorption pipeline; each molecular sieve column comprises a net cylinder, molecular sieve particlesare stacked in the corresponding net cylinder, a sealing adjusting cylinder is sheathed at the exterior of each net cylinder, and comprises a fixed cylinder part and a movable cylinder part, and eachmovable cylinder part is rotationally connected with the corresponding fixed cylinder part by using the center axis of the sealing adjusting cylinder as the rotation axis; each movable cylinder part is provided with an absorption position and a desorption position in the movement travel, and at least one part of the movable cylinder part is overlapped on the fixed cylinder part to expose the net cylinder at the desorption position. The oxygen preparation device has the advantage that the air contract area is greatly increased in the desorption process, and the air movement path is shortened, so that the desorption time is shortened.

Description

technical field [0001] The invention relates to oxygen preparation technology, in particular to an oxygen preparation device. Background technique [0002] Industrial production, commerce, medical treatment, food and other industries have the demand for oxygen use. The commonly used oxygen preparation method in the prior art is the molecular sieve oxygen production method. The principle is to purify the air and pass it through the molecular sieve under high pressure, and the molecular sieve will absorb nitrogen, etc. The remaining high-concentration oxygen is used for use. More strictly, the preparation of oxygen here refers to screening oxygen from the air, rather than generating oxygen. [0003] For example, the application publication number is CN107117584A, the application publication date is September 1, 2017, and the invention patent application titled "An Oxygen Generator and Oxygen Production Method" provides the oxygen preparation method through two adsorption tower...
