Abstract

The invention relates to the technical field of mechanical vacuum, and especially relates to a vacuum adsorbent prearranging device. The device comprises an adsorbent container, a scarifying structureand a traction structure, the internal of the adsorbent container is hollow to form an accommodating cavity, the accommodating cavity is in a vacuum state, the accommodating cavity is filled with anactivated adsorbent, the scarifying structure is in contact with the wall of the adsorbent container, the traction structure is connected with the scarifying structure and drives the scarifying structure to move, and the scarifying structure scarifies the wall of the adsorbent container when moving in order to expose the adsorbent. In the manufacturing process of a vacuum structure, the device isfirst placed in the vacuum structure, and then a vacuum pumping process is performed to make the adsorbent in the adsorbent container in a vacuum sealing state in order to ensure the adsorption capacity of the adsorbent. After the vacuum pumping is completed, the scarifying structure is driven by the traction structure to move and scarify the wall of the adsorbent container, so the adsorbent is exposed to the vacuum structure, and the activated adsorbent can exert a good adsorption effect to achieve the very good adsorption effect.

Description

technical field

[0001] The invention relates to the technical field of mechanical vacuum, in particular to a vacuum adsorbent preset device. Background technique

[0002] In fields such as superconducting applications and cryogenic liquid storage, it is necessary to apply vacuum insulation structures to keep equipment in a low heat leakage state. Due to factors such as air leakage or material outgassing in the vacuum structure, the vacuum degree gradually decreases, which in turn leads to an increase in the heat leakage level of the equipment and affects the use efficiency.

[0003] In order to improve the vacuum life of the equipment, a vacuum adsorbent is generally placed in the vacuum structure to absorb moisture, hydrogen, etc. in the structure. After the equipment is treated accordingly, put the activated adsorbent into the equipment before installation, and quickly vacuumize it. In the equipment with a long vacuuming cycle, this technology will cause the adsorbent to...
