Problems solved by technology

[0002] At present, most of the small oxygen generators in my country use the pressure swing adsorption process to produce medical oxygen. The key part of the oxygen generator is the adsorption tower, which is mainly composed of molecular sieves. When the oxygen generator is working, the compressed air passes through the molecular sieve packing layer. Nitrogen and oxygen are separated, and at the same time, the moisture or oil in the compressed air is absorbed by the molecular sieve, resulting in a decrease in the concentration of oxygen production. When the molecular sieve absorbs water or oil content greater than 7%, the molecular sieve loses the role of nitrogen and oxygen separation and loses oxygen production. Function; at present, small oxygen generators lack special molecular sieve protection devices, resulting in high cost of use, high maintenance costs, and waste of resources, which affects the normal oxygen inhalation of users

Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention will be further described

[0012] Such as figure 1 As shown, a molecular screening protector, the outer casing 3 is transparent and in the shape of a cuboid, one end of the upper end is connected to the air inlet pipe 1 by bolts, the other end has been connected to the air outlet pipe 2 by bolts, and the upper end of the outer casing 3 is evenly connected Three baffles 6 are connected to two baffles 6 at their lower ends, so that the upper and lower baffles 6 are distributed in a staggered manner, and the space is filled with high-efficiency adsorbent 7, which is medical silica gel, and the upper and lower sides of the outer ends are connected The fixed plate 5, the fixed plate 5, the baffle plate 6 and the shell 3 are formed by injection molding at one time, and there is a filling port 8 on one side of the shell 3, which is used to connect the silica gel plug 4. When in use, the high-efficiency adso...

Abstract

The invention relates to a molecular screening protector, comprising an outer housing. The molecular screening protector is characterized in that one end of the upper end of the outer housing is fixedly connected with an air inlet pipe, the other end is fixedly connected with an air outlet pipe, five baffle plates are connected in the outer housing, and efficient sorbents are filled between the baffle plates. Therefore, the molecular screening protector has the advantages of simple structure, increased service life of oxygenerator and easy repair, is specially used for absorbing water or oil in the air, and is particularly suitable for a small-size oxygenerator.
