[0002] In the process of industrial production or experimental research and development, some gases are often needed, and these gases are stored in gas cylinders. Because the gas in the gas cylinder is in a high-pressure state, and many gases are flammable or toxic, there are many issues that need to be paid attention to when placing the gas cylinder. Nowadays, many application fields use gas cylinder cabinets to place gas cylinders. Gas cylinder cabinets can improve local exhaust ventilation, and can also protect gas cylinders from fires outside the cabinet and protect surrounding objects from internal fires.

[0003] However, when the staff need to place the gas cylinders in the existing gas cylinder cabinets, the gas cylinders need to be moved to the inside of the cabinet and then fixed. However, during the placement process, due to the limitations of the two side walls of the cabinet, when the staff need to place multiple gas cylinders, it is easy to cause collisions between the gas cylinders, which may cause explosion and combustion accidents of flammable gases. It is not convenient to place the gas cylinders. And when internal gas leaks, it cannot be properly handled, which easily causes harmful gas leakage and endangers the personal safety of the staff. Therefore, a safe explosion-proof gas cylinder cabinet for laboratories is proposed to solve the above problems. Utility Model Content

[0025] To facilitate the placement of gas cylinders during use, two slide rails 15 are provided at the bottom of the cabinet 1 in this embodiment, and a placement component 4 is slidably connected to the two slide rails 15. A support plate 41 is provided on the placement component 4, and two sliders 42 are fixedly connected to the bottom of the support plate 41. The two sliders 42 are both slidably connected to the slide rails 15. A handle 43 is provided on the support plate 41, and two fixed seats 44 are provided on the top of the support plate 41.

[0026] As a preferred technical solution in this embodiment, in actual use, when placing the gas cylinder, the staff can first pull the handle 43 provided on the support plate 41 to make the support plate 41 slide on the slide rail 15, so that the support plate 41 slides out of the placement bin 12, and then the staff can place the gas cylinder to be placed in the fixing seat 44 on the support plate 41 to initially limit the gas cylinder, and finally push the support plate 41 into the placement bin 12, control the fixing frame 13 provided in the placement bin 12 to fix the gas cylinder, and the placement of the gas cylinder can be completed. This method can effectively avoid the collision of the gas cylinder due to space limitation during the placement process.

[0027] Embodiment 2:

[0028] See also Figure 2-5 In order to achieve a good treatment effect on the waste gas when the gas cylinder inside the cabinet 1 leaks, a partition 22 is provided inside the gas treatment component 2 in this embodiment. The partition 22 divides the inner cavity of the gas treatment component 2 into a first treatment chamber 23 and a second treatment chamber 24. A connecting hole 25 is provided at the bottom of the partition 22. By providing the first treatment chamber 23 and dividing the first treatment chamber 23 and the second treatment chamber 24 inside, it can achieve the effect of purifying the gas twice after the gas leaks, ensuring that it can be safer during use.

[0029] In order to achieve the effect of treating harmful gases, a filter layer 26 is provided in the first processing chamber 23 in this embodiment, and the filter layer 26 is located below the exhaust port 14. A discharge pipe 28 is provided at the bottom of the second processing chamber 24, and a solenoid valve 29 is provided on the discharge pipe 28. The filter layer 26 is provided so that the harmful gases can be treated for the first time during use. The discharge pipe 28 and the solenoid valve 29 are provided so that the treated wastewater can be effectively discharged during use. A discharge port 27 is provided on the second processing chamber 24, and an exhaust fan 21 is provided on the discharge port 27. A signal processor 5 is provided on the top of the exhaust fan 21. The exhaust fan 21 is provided so that the gas can be discharged. In order to achieve the effect of treating the exhaust gas, a water inlet 31 is provided on the water tank 3 in this embodiment, and two connecting conduits 32 are fixedly connected to the left side of the water tank 3. The two connecting conduits 32 are both provided with control valves 33. The other ends of the two connecting conduits 32 penetrate the top of the gas treatment component 2 and are provided with a spray head 34. The spray head 34 is located in the second treatment chamber 24.

[0030] As a preferred technical solution in this embodiment, when the gas detection device 16 detects that the internal harmful gas concentration exceeds the standard, the exhaust fan 21 is controlled to generate wind force, so as to extract the gas in the storage bin 12. During the discharge process, the harmful gas will first be filtered by the filter layer 26, and then the filtered gas will enter the second processing bin 24 through the connecting hole 25. At the same time, the control valve 33 is opened, and the water in the water tank 3 will enter the spray head 34 through the connecting conduit 32 to achieve the spraying effect, which can further treat the harmful gas dissolved in water.

[0031] The working principle of the above embodiment is:

[0032] 1. When placing the gas cylinder, the staff can first pull the handle 43 provided on the support plate 41 to make the support plate 41 slide on the slide rail 15, so that the support plate 41 slides out of the placement bin 12, and then the staff can place the gas cylinder to be placed in the fixing seat 44 on the support plate 41 to initially limit the gas cylinder, and finally push the support plate 41 into the placement bin 12, control the fixing frame 13 provided in the placement bin 12 to fix the gas cylinder, and the placement of the gas cylinder can be completed. This method can effectively avoid the collision of the gas cylinders due to space limitations during the placement process.

[0033] 2. When the gas detection device 16 detects that the concentration of harmful gases inside exceeds the standard, the exhaust fan 21 is controlled to generate wind force, so as to extract the gas in the storage bin 12. During the exhaust process, the harmful gases will first be filtered by the filter layer 26, and then the filtered gases will enter the second processing bin 24 through the connecting hole 25. At the same time, the control valve 33 is opened, and the water in the water tank 3 will enter the spray head 34 through the connecting conduit 32 to achieve the spraying effect, which can further treat the harmful gases dissolved in water.
