Description

Technical Field

[0001] The utility model relates to the technical field of soil detection and drying, and more specifically, to a drying pretreatment device for soil heavy metal detection. Background Art

[0002] Soil is one of the most important earth resources on which we depend for survival. Soil is the surface of the earth's land, composed of minerals, organic matter, water, air and organisms. It is a loose surface layer on land that is fertile and can grow plants. However, with the destruction of soil by humans in the process of technological development, some soils now contain heavy metals, which are very harmful to the human body. In order to determine the nutritional status of the soil, it is necessary to test the heavy metals in the soil.

[0003] Soil heavy metal detection requires drying of the soil. However, in the prior art, in order to avoid soil clumping after drying, the soil is usually turned over during the drying process, or the soil is ground after drying. In this process, dust is easily generated, which reduces the soil in the container, affects the specific gravity between the soil and heavy metals, and causes uneven test results. At the same time, it is easy to cause a large amount of dust in the drying device, which is difficult to clean. Utility Model Content
