[0002] Explosive dust, under certain conditions such as encountering sufficient oxygen or an ignition source, may cause an explosion, posing a serious threat to industrial production safety. Therefore, relevant factories generally install monitoring and alarm devices to detect the concentration of explosive dust.

[0003] Most existing dust concentration detection devices are installed by fixing them to the top or side wall. When the factory ceiling is high and the working area is large, if they are installed on the top, the high ceiling makes installation inconvenient and the dust detection effect of the monitoring and alarm device installed on the top is greatly reduced. On the other hand, if the device is installed on the side wall, the large working area makes it inconvenient to move the device, which reduces the monitoring accuracy of the monitoring and alarm device.

[0004] To address the aforementioned issues, we propose a safety monitoring and alarm device for explosive dust. Utility Model Content
