Description

Technical Field

[0001] This utility model belongs to the technical field of flat-plate centrifuge equipment, specifically relating to a centrifuge gas collection device structure. Background Technology

[0002] Traditional pharmaceutical and chemical industry uses top-discharge plate centrifuges, which operate with an open opening during the discharge process. Before the materials are dried after centrifugation, some materials will still volatilize and diffuse flammable, combustible, or toxic substances into the surrounding environment, resulting in poor on-site operating conditions and endangering the health of employees.

[0003] Existing technologies typically involve the organized collection and emission of gases throughout the room where the centrifuge is located, and a local exhaust hood is installed above the centrifuge. However, since the top discharge port of the top-discharge plate centrifuge is an open structure, it is still not possible to effectively prevent volatiles from escaping into the room. Utility Model Content

The structure is compact and easy to install, which can effectively reduce the emission of volatiles into the surrounding environment and improve the on-site operating environment.
