Air purifying net mechanism for oxygen generator

Abstract

The invention discloses an air purifying net mechanism for an oxygen generator. The air purifying net mechanism comprises a primary filtering ring, a restrictor ring, and a secondary filtering ring. The primary filtering ring is composed of a first U shaped part and a first round pipe part, which are integrated together. The restrictor ring is composed of following parts, which are integrally and sequentially arranged: a first connection ring direction part, a second connection ring direction part, and a third connection ring direction part. The interiors of the first connection ring direction part and the third connection ring direction part are a round cavity. The interior of the second connection ring direction part is a conical cavity. The secondary filter ring is composed of a second U shaped part and a second round pipe part, which are integrated together. The first U shaped part and the first connection ring direction part are connected through threads. The second U shaped part and the third connection ring direction part are connected through threads. The air purifying net mechanism can be rapidly disassembled into many sections, thus the air inlet filtering net can be cleaned more conveniently, linear filtered air amount is realized, the air flow is stable, the structure is simple, the use is convenient, and the device is very practical.

Description

technical field [0001] The invention belongs to the technical field of oxygen generators, and relates to an oxygen generator, in particular to an air purification net mechanism for an oxygen generator. Background technique [0002] The principle of the industrial oxygen generator is to use the air separation technology, first compress the air with high density, and then use the difference in the condensation point of each component in the air to separate the gas and liquid at a certain temperature, and then further rectify it; The working principle of the oxygen generator is to use molecular sieve physical adsorption and desorption technology. The oxygen concentrator is filled with molecular sieves, which can absorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected and purified to become high-purity oxygen. [0003] Oxygen generator tanks are usually equipped with filters at both ends, such as figure 2 shown. When working, the air pass...

Problems solved by technology

This method of direct embedding of the stainless steel wire mesh and the lower end often makes it concave or convex under the repeated action of gas pressure, causing the two ends to move to the middle, forming a ring at the embedding with the upper end ring and the chassis. Gaps, causing molecular sieves to leak nitrogen molecules and other impurities that interfere with oxygen purity

[0004] In addition, it is inconvenient to disassemble the filter screen of the existing oxygen generator when cleaning. Based on the above-mentioned deficiencies in the filter parts of the oxygen generator, a solution is now provided
