A method for unsealing the sealed package container of extraterrestrial celestial body samples

Abstract

The invention discloses a method for unsealing an extraterrestrial celestial body sample sealing packaging container and belongs to the technical field of vacuum. The device comprises a transition bin, an operation bin, an unsealing bin, a gas circulation purifying device, a gas cylinder and a vacuum pump. The unsealing bin is composed of an upper-end rigid section, a middle flexible section and a lower-end rigid section. The flexible section is detachably connected with the lower-end rigid section. When the flexible section is connected with the lower-end rigid section, an airtight space is formed by the unsealing bin. The transition bin is connected with the operation bin through a gate valve and communicates with the operation bin through a pipeline. The transition bin is connected with the vacuum pump through a pipeline. The gas circulation device communicates with the operation bin and the gas cylinder through pipelines. The upper-end rigid bin and the lower-end rigid bin of the unsealing bin are fixedly connected with the operation bin through a through hole in the upper surface of the operation bin and a through hole in the lower surface of the operation bin correspondingly, and the lower-end rigid section is connected with the vacuum pump through a pipeline. The unsealing bin communicates with the operation bin through a pipeline.

Description

technical field [0001] The invention relates to a method for unsealing a sealed package container of an extraterrestrial celestial body sample, and belongs to the field of vacuum technology. Background technique [0002] According to my country's deep space exploration development plan, my country will realize unmanned sampling and return of lunar samples by 2017. According to the follow-up development plan, my country will also carry out a series of deep space exploration projects such as Mars exploration, Mars sample sampling and return. In deep space exploration, after the sealed packaging container for collecting extraterrestrial celestial body samples is returned to the ground, according to the processing procedure of extraterrestrial celestial body samples, a series of steps such as unsealing of the sealed packaging container of extraterrestrial celestial body samples, processing and preservation of extraterrestrial celestial body samples are required. process. The r...

The patent application with the application number CN201310693058.4 proposes a device and method for a sample sealed container. The device can unseal the sample sealed container. The disadvantage is that it cannot circulate and purify water and oxygen in a high-purity nitrogen environment, and cannot maintain High-purity nitrogen environment, there is a risk of sample contamination

The patent application with the application number CN201610086872.3 proposes a method for collecting sealed containers for extraterrestrial celestial body samples. The device using this method can realize the unsealing of the sealed container for extraterrestrial celestial body sample collection and maintain a high-purity nitrogen environment. The disadvantage is that the device It has a three-chamber structure, and there are many vacuum motion mechanisms. There is a risk of jamming when the motion mechanisms operate in a vacuum environment. The reliability of the device is relatively low, the unsealing process is complicated, and the operation time is long. Risk of contamination during handling and storage
