[0003] Currently, hazardous chemical storage cabinets on the market are primarily conventional cabinets. These cabinets isolate hazardous chemicals, provide independent storage space, and are equipped with ventilation systems to reduce potential chemical risks. However, most existing cabinet ventilation systems are designed to directly exhaust internal air into the external environment, relying on external air to dilute the hazardous chemical vapors. While this approach reduces the concentration of hazardous chemicals indoors to a certain extent, it does not completely eliminate their impact on the environment and personnel health. To address this issue, we provide a diffusion-resistant hazardous chemical safety storage cabinet. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example: See Figures 1 to 6 According to an embodiment of the present utility model, a technical solution is provided: a diffusion-proof hazardous chemical safety storage cabinet, comprising a cabinet body 1 and a ventilation structure, wherein the cabinet body 1 has a storage space 2 for accommodating hazardous chemicals; the ventilation structure comprises a plurality of filter boxes 3 suitable for filling filter materials, wherein the plurality of filter boxes 3 are connected in series by a pipe 4 to form a ventilation duct, wherein the two ends of the ventilation duct are spaced apart and both are connected to the storage space 2, and a blowing device 5 such as a blower or an axial flow fan is provided at a position located at at least one end of the pipe 4. When implementing the above solution, according to the type of hazardous chemicals stored in the cabinet body 1, appropriate filter materials are selected and filled into the filter boxes 3, and then the blowing device 5 is started to circulate the air in the storage space 2 in the ventilation duct. Through this internal circulation method, not only the concentration of harmful gases inside the storage cabinet is reduced, but also the potential harm of these gases to the external environment and personnel health is completely prevented.

[0026] In this exemplary embodiment, the ventilation structure further includes a branch pipe 6, each end of which is connected to the pipeline 4 connecting the two sides of the filter box 3. A three-way valve 7 is provided at the connection between the branch pipe 6 and the pipeline 4. Because different types of hazardous chemicals may require different filter materials, each filter box 3 can be loaded with different filter materials. Then, based on the type of hazardous chemicals actually placed in the storage space 2, the three-way valve is used to control the direction of airflow in the pipeline 4. For example, when a certain filter box 3 is not needed, the three-way valve can be used to control the flow of air, causing it to bypass that filter box 3 and flow through the branch pipe 6. Of course, if a certain filter box 3 is needed, the three-way valve can be used to control the flow of air, causing it to flow through that filter box 3. In this way, air flowing through the pipeline 4 can be selectively directed to pass through or bypass a filter box 3 loaded with a specific filter material, depending on the type of hazardous chemical actually placed in the storage space 2, thereby meeting the filtering requirements of different types of hazardous chemical exhaust.

[0027] In this exemplary embodiment, the ventilation structure also includes a cooling box 8, which is buried underground at the installation location of the cabinet 1, and a portion of the pipe 4 passes through the cooling box 8. Water is added to the cooling box 8. Since the cooling box 8 is buried underground, the water temperature therein is lower than the temperature of the air in the storage space 2. When the air flows through the pipe 4, the air temperature will decrease, and ultimately the temperature of the air flowing back to the storage space 2 will decrease, thereby achieving the purpose of cooling the interior of the storage space 2. Preferably, the portion of the pipe 4 that passes through the cooling box 8 is bent in an S shape. This design can increase the length of the pipe 4 in the cooling box 8, thereby extending the time that the air in the pipe 4 flows through the cooling box 8 and improving the cooling effect.

[0028] In this exemplary embodiment, a partition 9 is provided inside the cabinet 1, dividing the interior of the cabinet 1 into a U-shaped storage space 2. The two ends of the ventilation duct are connected to the two ends of the storage space 2. This arrangement allows the air in the storage space 2 to flow along the U-shaped channel when the blower 5 is activated, ensuring that all air in the storage space 2 can effectively flow into the ventilation duct and be purified. This design optimizes air circulation and improves the safety of hazardous chemical storage.

[0029] In this exemplary embodiment, a detection mechanism is installed within storage space 2. The detection mechanism includes an oxygen content detector 10, a temperature and humidity detector 11, and a combustible gas detector 12, all located within storage space 2, as well as a central controller 14 connected to these detectors and located outside cabinet 1. The provision of the detection mechanism enables real-time monitoring and early warning of key safety indicators in storage space 2, enabling timely detection of potentially dangerous conditions such as elevated combustible gas concentrations, abnormal oxygen levels, and temperature and humidity fluctuations. This effectively prevents fires, explosions, and hazardous chemical reactions, protecting the health and safety of personnel.

[0030] In this exemplary embodiment, multiple filter boxes 3 are installed on the top of the cabinet 1. The filter boxes 3 include a box body and a box cover. The box cover is hinged to the box body for easy opening and closing. A ladder 13 is installed on the side wall of the cabinet 1. This allows workers to easily climb to the top of the cabinet to replace the filter material. This design takes into account the convenience of maintenance, ensures the efficient operation of the ventilation structure and the continued performance of the hazardous chemical storage cabinet.

[0031] Working principle: First, it is necessary to select appropriate filter materials according to the types of hazardous chemicals stored in the storage space 2 of the cabinet 1 and fill them in the filter box 3 located on the top of the cabinet 1. Then, start the blowing equipment 5, such as a blower or an axial flow fan, to establish an air circulation in the storage space 2, thereby reducing the concentration of harmful gases and preventing them from causing harm to the environment and personnel; by connecting the pipeline 4, the branch pipe 6 and the three-way valve 7 set on the pipeline 4 to the filter box 3, the path of the air flow can be controlled according to actual needs, so that it flows through a specific filter box 3 or bypasses it, so as to effectively filter different types of hazardous chemicals; in addition, in order to control the temperature of the storage space 2, the ventilation structure also includes a buried In the underground cooling box 8, the air will be cooled due to the low water temperature when flowing through the cooling box 8, thereby reducing the temperature inside the storage space 2; the partition 9 inside the cabinet 1 is designed to form a U-shaped storage space 2, which optimizes the air circulation effect and ensures that all air is effectively purified; at the same time, the detection mechanism installed on the cabinet 1 monitors key safety indicators in real time, such as oxygen content, temperature and humidity, and combustible gas concentration, to promptly warn of potential dangers and prevent the occurrence of fire, explosion and harmful chemical reactions; finally, in order to maintain and replace the filter material, the side wall of the cabinet 1 is equipped with a ladder 13, which is convenient for staff to climb to the top of the cabinet to replace the filter material, ensuring the efficient operation of the entire system and the safe storage of hazardous chemicals.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
