Description

Technical Field

[0001] The utility model belongs to the technical field of soil detection, and in particular relates to a soil metal detection device. Background Art

[0002] With the rapid development of industrialization and urbanization, soil pollution is becoming increasingly serious, especially heavy metal pollution. The accumulation of heavy metals in the soil not only affects the soil quality, but also may enter the human body through the food chain, posing a threat to human health. Therefore, it is of great significance to accurately and quickly detect the content of heavy metals in the soil.

[0003] In the process of soil metal detection, dissolving soil in water and adding reaction solution is a common pretreatment step, the purpose of which is to convert the metal components in the soil into a detectable form. However, this method does involve a filtering step to remove soil particles and other insoluble impurities, thereby protecting the subsequent photoelectric detector from contamination and damage. The filter plays a key role in this process; however, soil particles and other impurities are easy to form clogging on the filter, resulting in a decrease in filtration efficiency. Frequent replacement of filters will increase detection costs, and maintaining filters requires specialized skills and tools, which increases operational complexity and time costs.
