[0002] Dust concentration detection is a technology that monitors suspended particles in the air, such as dust, smoke, industrial dust, etc. By measuring the concentration of these particles, we can evaluate the air quality, which is crucial for environmental protection, industrial production safety and public health. Especially in industrial activities such as mining, metallurgy, and cement manufacturing, the control of dust concentration is particularly critical. In these industrial environments, in order to prevent explosion accidents caused by excessive dust concentration, it is necessary to install dust concentration detection equipment. At present, the dust concentration detection equipment used in these industries mostly adopts a fixed integrated design, which ensures the integrity, stability and sealing of the equipment.

[0003] However, existing dust concentration detection equipment has some limitations in practical use. These devices cannot flexibly install or remove protective components according to specific usage conditions, which brings inconvenience to the maintenance of laser probes. At the same time, the glass panel used to protect the laser probe cannot be easily disassembled, connected, cleaned and maintained, which limits the flexibility of use and maintenance efficiency of the equipment. Based on this, we propose a dust concentration detection explosion warning device to solve the above-mentioned problems. Utility Model Content
