Description

Technical Field

[0001] The utility model belongs to the field of safety glove boxes, and in particular relates to an anti-pollution safety glove box with an air replenishing function. Background Art

[0002] The glove box is a closed box that provides an experimental environment isolated from the outside world. It is mainly used in the chemical, physical, material, nuclear and other industries to prevent moisture and oxygen in the air from reacting with test materials or to prevent the spread of toxic test materials. It also has a circulating purification system that continuously absorbs moisture and oxygen in a circulating purification manner to create a low-water and low-oxygen experimental environment.

[0003] There is a transition cabin on the glove box for transferring materials. The transition cabin has inner and outer doors. When transferring materials, the air entering when the materials are put in is exhausted by vacuuming and then replenishing the atmosphere in the box, so that the low-water and low-oxygen atmosphere in the glove box is not destroyed by air when the door of the transition cabin is opened.

[0004] Therefore, the atmosphere in the transition cabin is the same as the atmosphere in the glove box, so when the outer door of the transition cabin is opened, the atmosphere in the glove box will diffuse into the room. If the atmosphere in the glove box contains harmful substances, it will pollute the environment inside the laboratory, thereby seriously affecting the health of laboratory workers.

[0005] In view of this, we proposed an anti-contamination safety glove box with air replenishment function to improve the above problems. Utility Model Content
