[0016] Combination Figures 1 to 3 As shown, the present embodiment provides a corrosion-resistant and high-temperature resistant dangerous goods cabinet, including a cabinet body 1, in which an inner liner 2 for placing dangerous goods is detachably provided, and an exhaust channel 21 is provided on the lower side of the bottom of the inner liner 2, and the exhaust channel 21 is connected to a filter component to filter the volatile gas discharged from the inner liner 2; a layer of aluminum silicate ceramic fiber cotton layer is provided on the inner wall of the inner liner 2, and a layer of vinyl resin layer is formed on the outside of the aluminum silicate ceramic fiber cotton layer to make the inner liner 2 corrosion-resistant.

[0017] In this embodiment, the cabinet 1 is provided with an inner liner 2 for placing dangerous drugs or dangerous chemicals. In the cabinet 1, a plurality of placement grids can be formed by layered partitions to facilitate the fixing and placement of dangerous goods. The cabinet 1 presents an upper and lower structure. A filter device 4 and an integrated master control module are provided above the cabinet 1. The cabinet 1 can also be provided with a multi-layer structure for classified placement of dangerous goods of different categories and heights. A control display screen 3 is provided in front of the cabinet 1. The control display screen 3 is connected to the master control module of the cabinet 1 so as to control the dangerous goods management cabinet through the control display screen 3.

[0018] The inner liner 2 can be detachably arranged in the cabinet 1, and can be fixed by a locking device, or a snap-fit ​​structure matching the inner liner 2 can be arranged on the cabinet, so that the inner liner 2 can be stable when placed in the cabinet 1, and it is convenient to disassemble and replace. The layered partition 6 can be arranged at a suitable position of the inner liner 2 as needed to separate the inner liner 2 into several layers for easy placement. Furthermore, a vent and a liquid collecting tank 61 are also arranged on the layered partition 6. The liquid collecting tank 61 can collect dangerous goods in the tank when dangerous goods accidentally leak out, so as to prevent the dangerous goods on the upper layer from dripping onto the dangerous goods on the lower layer and causing danger. Here, the vent can be arranged on the side of the layered partition 6, and the liquid collecting tank 61 can be arranged in the middle of the layered partition 6.

[0019] In this embodiment, the inner liner 2 is formed with a layer of aluminum silicate ceramic fiber cotton to improve the temperature resistance, and a layer of vinyl resin is formed on the outside of the aluminum silicate ceramic fiber cotton layer to make the inner liner have corrosion resistance. The vinyl resin layer here is a 907 vinyl resin coating. Aluminum silicate ceramic fiber cotton has AI-level fireproof function, and can withstand a high temperature of 1260°C to the extreme. It is safer and heat-insulating than traditional asbestos. Even under an open flame of 600-1000 degrees Celsius, it can keep the surface of the box below 50°C. All components of vinyl ester resin participate in cross-linking and curing, no small molecules are precipitated, the cross-linking density is high, and the solidified material is dense and solid; the ester bond content is low, it is both acid-resistant and alkali-resistant, and has a certain resistance to oxidizing media and organic solvents. Therefore, this embodiment can effectively prevent corrosion and improve surface strength and toughness by coating a layer of 907 vinyl resin on the inner wall of the inner liner 2. Through this scheme, the inner liner 2 is subjected to experimental high temperature resistance and corrosion resistance tests, and the experimental data of the vinyl resin layer as shown in Table 1 are obtained:

[0020] Table 1

[0021] Serial number project index 1 Bond Strength ≥2MPa 2 Heat resistance 250℃, constant temperature for 1h, no surface changes after cooling 3 Corrosion resistance After soaking in 30% concentrated sulfuric acid for 30 days, the coating has no cracks, bubbles or peeling 4 Aging resistance After 500h test, the coating has no cracks, blistering, peeling or powdering.

[0022] It can be seen from Table 1 that the inner liner 2 provided with an aluminum silicate ceramic fiber cotton layer and a vinyl resin layer has strong bonding strength, heat resistance, corrosion resistance and aging resistance.

[0023] In one embodiment, the thickness of the vinyl resin layer of the side wall of the inner liner 2 is 5 μm to 3 mm to ensure that the inner liner 2 has good corrosion resistance, and the thickness of the vinyl resin layer at the bottom of the inner liner 2 is greater than the thickness of the vinyl resin layer of the side wall of the inner liner 2. This is because the present embodiment adopts a ventilation structure that intakes air from the top and exhausts air from the bottom. Therefore, the volatilized gas of the dangerous goods acts on the bottom of the inner liner 2 for a longer time, and the bottom of the inner liner 2 is more susceptible to corrosion. Therefore, setting the bottom vinyl resin layer to be thicker than the side wall vinyl resin layer can improve corrosion resistance.

[0024] Continue to combine Figures 2 to 3 As shown, in this embodiment, the inner tank 2 is arranged on the inner side of the cabinet 1, and an air intake interlayer 11 is formed between the inner tank 2 and the side of the cabinet 1, and the air intake interlayer 11 is connected to the air inlet of the filter device 4. A fresh air inlet 12 can be provided at the bottom or top of the cabinet, and an exhaust channel 21 is provided at the bottom of the inner tank 2; the air inlet 12 of the cabinet 1 is connected to the exhaust channel 21 of the inner tank 2. In another embodiment, since a filter assembly (not shown) is provided on the exhaust channel 21, the exhaust channel 21 can also be directly connected to the outside, and the gas discharged after being filtered by the filter assembly will not cause corrosion to the cabinet.

[0025] Combination Figure 3 As shown, in one embodiment, a fan 5 is provided at the top of the filter device 4, and the fan 5 is a negative pressure fan, which can generate negative pressure in the air intake interlayer 11, so as to draw the air in the air intake interlayer 11 or the air directly coming in from the air inlet 12 to the filter device 4, and then enter the air inlet of the liner 2 through the filter device 4. The filter device 4 is connected to the top air inlet of the liner 2, and the fan 5 is suitable for sucking the gas discharged from the exhaust channel of the liner 2 or the air entering from the air inlet 12 into the filter device 4 through the air intake interlayer 11 for filtration, and introducing the filtered gas into the liner 2 to form a circulating airflow, thereby reducing the gas in the liner 2 from being directly emitted into the air.

[0026] The filter device 4 includes a primary filter layer, an activated carbon filter layer and an acid gas filter layer arranged in sequence from top to bottom, wherein the primary filter layer includes a non-woven fabric for effectively filtering dust particles larger than 5 μm, and the non-woven fabric is fixed by a metal mesh frame; the activated carbon filter layer includes activated carbon cotton to effectively absorb formaldehyde or VOC or odor; the acid gas filter layer includes a honeycomb adsorption module pressed by an SDG adsorption block to absorb acid gas. The SDG adsorption block is a prior art product, which has a porous structure and can effectively absorb acid gas. Here, through three layers of continuous filtration, dust, gas or impurities of different sizes are adsorbed and filtered in turn, thereby improving the adsorption effect of corrosive gas. This setting solves the problem that there is no ventilation duct in the storage place of the existing chemical cabinet, and the corrosive gas volatilized by the chemical reagent will cause damage to the environment and indoor equipment. Therefore, this solution can make the volatilized corrosive gas be recycled after being adsorbed by the filter device 4. In another embodiment, the filter device 4 can be replaced according to the type of dangerous drugs or dangerous chemicals placed in the inner container 2, thereby improving the compatibility and applicability of the dangerous goods management cabinet. The filter assembly can be set to the same configuration as the filter device.

[0027] Through the scheme of this embodiment, the corrosion resistance and high temperature resistance of the dangerous goods cabinet can be improved, and the service life of the cabinet can be increased.

[0028] It should be understood that the above are only preferred implementations of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.

[0029] The above description of the drawings used in the implementation manner only shows certain embodiments of the utility model and should not be regarded as limiting the scope. For ordinary technicians in this field, other relevant drawings can be obtained based on these drawings without paying creative work.
