Abstract
Description
Technical Field
[0001] This utility model relates to the field of experimental equipment technology, specifically to an inert operating chamber. Background Technology
[0002] An inert operating chamber is a closed working space that maintains a low-oxygen, low-humidity environment using inert gases (such as nitrogen and argon). It is widely used in the preparation of air-sensitive materials, experimental operations, and production processes.
[0003] Currently, due to the strict requirements of reagents, some inert operating chambers need to maintain a certain pressure and dryness. During air drying, airflow will be generated in the operating chamber. When the staff is making precise measurements of the reagents, the thrust exerted by the airflow will cause the container holding the reagents to shake. Under such circumstances, the data measured by the precision weighing instrument will be unstable and may even produce errors, thus affecting the accuracy of the data in subsequent experiments.

If waste or garbage is generated during the operation, the staff members put the waste into the gap between the partition plates 11. Driven by the servo motor 9, the partition plates 11 rotate intermittently and transport the waste to the collection chamber 14, where it falls into the collection box 15 for collection under gravity.
