Description

Technical Field

[0001] The utility model relates to the technical field of management cabinets, and more specifically, to a hazardous chemical management cabinet. Background Art

[0002] The storage management cabinet for dangerous chemical substances is mainly used for storing chemical reagent bottles or other chemical substances, and has an automatic management function. Its main functions include storing chemical substances, a weighing module, waste liquid collection, etc., as well as the RFID identification function for automatically managing chemical substances.

[0003] In the existing published literature, the patent with the patent publication number CN113000075A discloses a laboratory hazardous chemical intelligent management cabinet. This management cabinet has multiple groups of oil-passing holes opened on the oil-separating flexible plate; on the placing plate inside the hazardous chemical management cabinet, a placing plate with a slow descent is added. When a container filled with hazardous chemicals is placed inside the cabinet body, the placing plate can descend, reducing the impact force when the container is directly placed inside the cabinet body, and reducing the risk that the hazardous chemicals will be damaged inside the cabinet body; however, this management cabinet has the following defects;

[0004] When the management cabinet is in use and a leakage of hazardous chemical reagents occurs and is collected, it will cause pollution of the hazardous chemical liquid, thus extremely easily leading to the leakage of the hazardous chemical liquid, making it difficult to safely seal and collect and process the hazardous chemical waste liquid, resulting in poor safety in collecting hazardous chemicals.
