[0021] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0022] See also Figures 1 to 4 FIG. 1 is an embodiment of the present utility model.

[0023] The explosion-proof chemical harmful substance self-purification device in this embodiment includes a box body 1, a purification device 2, an axial flow fan 3, a sensor 5 and an explosion-proof box 6 and other structures.

[0024] like Figure 2As shown, the box body 1 includes a bottom 11 and a top cover 12, the bottom 11 and the top cover 12 are connected up and down by hinges, and are fixed with handles 14 on the left and right sides to ensure the overall sealing performance. In this embodiment, the box body 1 is provided with an air inlet 111 on the side, and the air inlet 111 is provided with a ventilation pipeline 112 that is sealed and connected to the purification port opened on the cabinet A to be purified. Figure 3 and Figure 4 As shown. However, it is not limited to this. It can be set to the left, right or bottom according to the needs of the cabinet, with ease of installation as the main consideration. The air inlet can be set in advance and opened in the form of a valve according to the needs of use. An air outlet 121 is provided on the top cover 12 for the purified gas to be discharged, and a sensor connector 13 is also provided on the top cover 12 for quick sealing connection with the sensor 5. Adjustable support feet are provided at the bottom of the box body 1, so that the height of the entire box body can be increased according to the use environment to facilitate the installation of the ventilation pipeline. At the same time, in order to reduce noise during operation, a sound-absorbing cushion is provided at the bottom of the adjustable support foot.

[0025] like Figure 4 As shown, an interlayer fixing plate 7 is provided in the box body 1. The interlayer fixing plate 7 seals the bottom of the box body 1, the air inlet 111 is located at the lower end of the interlayer fixing plate 7, and the fan 3 and the sensor connector 13 are both located on the upper layer of the interlayer fixing plate 7. The interlayer fixing plate 7 is provided with an air vent which is sealed and connected to the air inlet of the purification device 2. The interlayer fixing plate 7 is provided with a fixing structure for fixing the purification device, the fixing structure is provided with a guide groove, and the purification device is provided with a guide card strip corresponding to the guide groove. The replacement of the purification device can be completed accurately and quickly by docking the guide groove and the guide card strip. The purification device includes a HEPA high-efficiency filter layer and a chemical adsorption filter layer. Double-layer filtration can filter various harmful gases, particles, etc. such as TVOC, acid, alkalinity, etc.

[0026] The axial flow fan 3 is arranged in the box body 1, and the air outlet end of the axial flow fan 3 is connected with the air outlet. The fan is inside the cabinet body, and the axial flow fan that meets the explosion-proof requirements is selected to increase the air flow inside the device, so that the purification device and the inside of the cabinet are continuously maintained in a negative pressure state, which can not only accelerate the circulation of air in the cabinet and the purification effect, but also ensure that harmful substances will not leak from other areas.

[0027] The sensor 5 is fixed to the box body 1 through a fixing seat 8, and the sensor 5 is sealed and connected to the sensor connector 13. The sensor 5 is an explosion-proof sensor, which is used to monitor the quality of the filtered air and ensure that the device is in an effective working state. At the same time, there is an explosion-proof sound and light alarm 9 on the sensor 5, which can sound and light alarm when the sensor detects an abnormal state. A fixing slot 51 is provided on the top of the sensor 5 to fix the sound and light alarm 9.

[0028] The explosion-proof box 10 is fixed on the box body 1. Various control electrical components are arranged in the explosion-proof box, such as the control components of fan operation, the data storage and control components of the sensor, etc. The electrical components are connected to the axial flow fan, the sensor and a power supply through the explosion-proof pipe and the explosion-proof joint 101.

[0029] See also Figure 1 When in use, place the device on top of the hazardous chemicals storage cabinet, and according to the actual situation on site, select the right interface or the left interface for pipe connection, connect the purification device and the cabinet together; connect the power supply to start working. If the adsorption of the purification device becomes saturated after long-term use, and the quality of the filtered air is lower than the standard requirement, the sensor will alarm when it detects air abnormalities. At this time, the purification device needs to be replaced. To replace the purification device, you first need to open the top cover of the purification device and support it with the support rod 71 folded and stored on the interlayer fixing plate 7, then remove the fixing device and take out the filter layer, and restore it after replacing the filter layer.

[0030] The utility model only needs to open a purification port on the existing cabinet, and does not need to replace the entire cabinet, which greatly saves costs.

[0031] The above-described embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Equivalent changes and modifications made to the present invention by those skilled in the art should all fall within the scope of the claims attached to the present invention.
