Abstract

The invention discloses a sample preparation system for heavy metal soil detection. The sample preparation system comprises a drying device and a screening device; the drying device comprises a material distribution unit and a drying box; and the screening device comprises an intercepting assembly, a classifying assembly and a dumping assembly. Efficient batch treatment of soil samples is achieved through the material distribution unit with the flattening and compacting functions, and the space utilization rate of the drying device is increased; and a grid structure with dynamically variable grid sizes is realized by utilizing the intercepting assembly formed by overlapping and matching two layers of rod pieces, and efficient screening of dried samples is realized.

Description

technical field [0001] The invention relates to the field of soil detection, in particular to a sample preparation system for heavy metal soil detection. Background technique [0002] There are relatively serious heavy metal pollution in many lands. In order to understand the specific situation of soil pollution and make targeted preparations to repair the soil, it is necessary to sample the soil on site, and then dry and screen the retrieved samples. deal with. Most of the existing drying equipment adopts general-purpose drying equipment, and its internal space design is unreasonable, resulting in low efficiency of sample preparation. Therefore, it is necessary to invent a sample preparation system for heavy metal soil detection with convenient operation and efficient multi-batch processing. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a sample preparation system for h...
