Description

Technical Field

[0001] The utility model relates to the technical field of dust monitoring, in particular to a dust monitoring device. Background Art

[0002] Construction sites are often the main source of dust. A large amount of dust particles will not only cause harm to the workers' respiratory system, but may also cause eye discomfort, skin itching and other problems. Through dust monitoring equipment, we can grasp the concentration and distribution of dust on the construction site in real time. Once it is found to exceed the standard, we can immediately take measures to intervene, such as increasing the number of watering times, optimizing construction technology, etc., thereby effectively reducing the impact of dust on workers' health. Existing dust monitoring equipment is generally composed of columns, boxes and particulate matter sensors. Particulate matter sensors monitor dust and have a simple structure and are easy to use. However, their columns are generally integrated. During the installation process, the monitoring height cannot be adjusted according to the surrounding environment. It is easily blocked by buildings or too high to affect its own stability. At the same time, the air cannot be dried. Humid air can easily affect the accuracy of monitoring. At the same time, the mixture of humid air and dust can easily contaminate the monitoring flow channel, resulting in general use effect. Utility Model Content

The cooling fan dissipates heat from the hot end of the refrigeration plate through the heat dissipation block. During use, the refrigeration plate can be used to cool the monitored air, reduce the humidity of the air, reduce the impact of water vapor on dust monitoring, and improve the accuracy of dust monitoring.
