Molecular sieve filling system for molecular sieve adsorbing device and filling process of molecular sieve filling system

Abstract

The invention discloses a molecular sieve filling system and a filling process thereof, and aims at providing a molecular sieve filling system for a molecular sieve adsorbing device. The molecular sieve filling system is capable of effectively eliminating and changing the phenomenon that medical molecular sieve oxygen generating equipment is in contact with a large amount of water and is damaged when a material is filled. The invention further provides the filling process of the molecular sieve filling system for the molecular sieve adsorbing device. The molecular sieve filling system for the molecular sieve adsorbing device comprises a nitrogen cylinder (1), a molecular sieve raw material barrel (2), a molecular sieve adsorbing tower (3), a negative pressure machine (4) and a vertical vibrating platform (5) which are sequentially connected through a pipeline. According to the filling process of the molecular sieve filling system, a molecular sieve is firstly filled with dried nitrogen in a positive pressure nitrogen filling manner, the raw material of the molecular sieve is pushed to enter a target tank body by using an adjustable pressure, and a positive pressure pushing and negative pressure sucking manner is adopted, pushing and adjustable sucking pressure are realized. The molecular sieve filling system and the filling process thereof are applied to the technical field of filling of the raw material of the molecular sieve of the molecular sieve adsorbing device.

Description

technical field [0001] The invention relates to a molecular sieve filling system used in a molecular sieve adsorption device, and also relates to a filling process of the system. Background technique [0002] At present, the molecular sieve raw materials of molecular sieve adsorption air separation equipment are generally filled by manual ladle or equipment with compressed air, and then filled tightly by overall vibration or direct vibration of vibrating rods in the cavity. Because the molecular sieve raw material has strong moisture adsorption characteristics and brittleness, a good filling process should realize the protection of the molecular sieve raw material, which can not only isolate water molecules, but also realize reasonable compaction of the molecular sieve without damaging the molecular sieve raw material. [0003] For example, the Chinese patent with publication number 202700319 discloses a molecular sieve filling device, which includes a steel plate, a wide ch...

Problems solved by technology

This method completely ignores the characteristics of molecular sieve raw materials, because apparent moisture will inevitably appear in the air after being pressurized by the air compressor, which will lead to rapid failure of the molecular sieve raw materials; at the same time, the air pressure after being pressurized by the air compressor is generally at About 7bar, under this pressure, the molecular sieve raw material is sent from the transfer storage tank to the target tank, which will inevitably cause sharp friction and impact of the molecular sieve, which will cause the molecular sieve to be pulverized, and the life of the molecular sieve will be greatly reduced
