AI Technical Summary

Technical Problem

In existing high-efficiency molecular sieve adsorption nitrogen generators, the gas is unevenly distributed when it enters the inner cylinder and comes into contact with the molecular sieve, resulting in the molecular sieve's adsorption capacity not being fully utilized, making it difficult to meet the industrial production demand for high-purity, high-yield nitrogen.

Method used

It adopts a conical filter plate and air passage structure. The conical filter plate is rotated by a rotating rod to achieve uniform gas spraying onto the molecular sieve. Combined with the filter cotton layer and gas flow plate, it ensures that the gas is in full contact with the molecular sieve. The impurities are automatically separated and collected through the guide groove and collection chamber.

Benefits of technology

It improves the purity of gas treatment and nitrogen production efficiency, prevents impurities from clogging, enhances the adsorption capacity of molecular sieves, and ensures efficient nitrogen production.

Abstract

The utility model relates to the field of nitrogen making machines, in particular to an efficient molecular sieve adsorption type nitrogen making machine. The device comprises a reaction cylinder, and an inner cylinder is fixedly connected to the interior of the reaction cylinder. The conical filter plate in the treatment mechanism is in a big-end-down shape, impurities in gas can be effectively filtered out, the unique shape of the conical filter plate can guide the impurities to slide to the flow guide groove along the inclined face, then the impurities are collected in a centralized mode through the collecting cavity, the impurities are prevented from entering the inner cylinder to affect the performance of the molecular sieve, and the purity of gas treatment is guaranteed; the nitrogen generation efficiency and quality are improved; moreover, the driving motor drives the conical filter plate to rotate, so that the gas treatment efficiency and quality of the nitrogen making machine can be remarkably improved, the contact frequency of the surface of the conical filter plate and impurities in the gas is greatly increased in the rotating process, and the impurity intercepting effect is remarkably enhanced; and meanwhile, the impurities are promoted to move towards the edge of the filter plate and slide to the diversion trench along the inclined surface due to the centrifugal force.
