Description

Technical Field

[0001] The utility model relates to the technical field of environmental detection, in particular to a soil sample dehumidifying device for environmental detection. Background Technique

[0002] Environmental monitoring uses GIS technology to design an environmental monitoring network. The information collected by environmental monitoring can be stored and displayed in real time through GIS, and detailed site monitoring and analysis can be carried out on the selected evaluation area. Soil detection is an important branch of environmental detection. When people take soil samples, before analyzing relevant indicators such as soil pH, organic matter, CEC, nutrient elements, trace elements, and heavy metal element contents, the soil samples need to be dehumidified. When dehumidifying, a soil sample dehumidifying device will be used. It is very difficult to air-dry the soil at the bottom of the existing soil dehumidifying device, which not only increases the time for soil air-drying, but also makes the soil air-dried unevenly, which is not conducive to people's detection of the soil.
