Description

Technical Field

[0001] This utility model relates to the technical field of hazardous chemical management cabinets, specifically to a hazardous chemical management cabinet equipped with a ventilation and filtration structure. Background Technology

[0002] Hazardous chemicals refer to highly toxic chemicals and other chemicals that possess properties such as toxicity, corrosiveness, explosiveness, flammability, and combustion-supporting properties, posing a threat to human health, facilities, and the environment.

[0003] There are two main methods for storing hazardous chemicals in laboratories: the first is a conventional sealed cabinet, which stores hazardous chemicals in a sealed cabinet to prevent toxic odors from leaking into the laboratory as much as possible; the second is a ventilated cabinet, which has an opening at the top where an exhaust duct is connected to connect the cabinet to the main ventilation system, and the negative pressure of the main duct exhausts the toxic gases from the cabinet to the outside.

[0004] The existing management cabinets for storing hazardous chemicals have the following shortcomings:

[0005] 1) Hazardous chemicals are toxic and harmful chemicals. If toxic and harmful chemicals are stored in sealed management cabinets, the toxic and harmful substances produced or volatilized by the chemicals will remain in the sealed management cabinets and will not be effectively eliminated. In addition, the airtightness of the sealed management cabinets is not absolute. There are always some gaps in the sealed management cabinets. Toxic and harmful gases will leak into the laboratory through the gaps in the cabinets, causing the toxic and harmful gases to be released and accumulated in the laboratory, affecting air quality, affecting the health of personnel, and causing harm to the laboratory personnel.

[0006] 2) Although ventilation cabinets can discharge the toxic and harmful gases emitted by hazardous chemicals, existing ventilation cabinets only have one opening at the top. They are mainly used to discharge the toxic and harmful gases emitted by hazardous chemicals on the top or upper layers. It is difficult to discharge the toxic and harmful gases emitted by hazardous chemicals placed on the bottom or lower layers. This affects the efficiency and effect of the emission of hazardous chemical gases in the cabinet. It can also easily lead to insufficient air circulation inside the cabinet, which is not conducive to the storage of hazardous chemicals. Utility Model Content

[0007] The technical problem this utility model aims to solve is to address the shortcomings of existing technologies by providing a hazardous chemical management cabinet with exhaust vents on the opposite side wall of each storage layer. An exhaust duct is connected to the exhaust vents of each storage layer, and an exhaust filtration mechanism is activated. This allows toxic and harmful gases emitted by the hazardous chemicals stored in each layer to flow from the exhaust vents to the exhaust duct, and then from the exhaust duct to the exhaust filtration mechanism for filtration. This effectively filters and removes the toxic and harmful gases emitted by the hazardous chemicals in each storage layer, improving the emission efficiency of harmful gases, enhancing the air circulation inside the cabinet, and ensuring the safe storage of hazardous chemicals.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A hazardous chemical management cabinet with a ventilation and filtration structure includes a cabinet body, several trays, and an exhaust filtration structure.

The air outlet of the exhaust fan is connected to the exhaust duct, and the filter is installed at the connection between the exhaust fan and the exhaust duct.

[0011] Furthermore, the air inlet filtration structure includes a filter fixing plate and filter cotton. The filter fixing plate is provided with a plurality of filter holes, which are evenly distributed on the filter fixing plate. The filter cotton is fixed on the filter fixing plate and aligned with the air inlet hole on one side wall of each storage layer.

[0012] Furthermore, the hazardous chemical management cabinet includes a side fixing frame, which is installed on one side of the management cabinet body.
