Description

Technical Field

[0001] The invention relates to a shrinking device, in particular to a dry dispersed sediment sample grinding material shrinking integrated device, belonging to the technical field of sediment sample shrinking. Background Art

[0002] Marine sediments refer to the general term for seabed sediments formed by various marine sedimentation processes. Materials deposited on the seabed with seawater as the medium. Sedimentation can generally be divided into three different processes: physical, chemical and biological. Since these processes are often not carried out in isolation, sediments can be regarded as geological bodies produced by comprehensive actions. Traditionally, sediments are divided into nearshore sediments (0-20 meters), shallow sea sediments (20-200 meters), semi-deep sea sediments (200-2000 meters), and deep sea sediments (greater than 2000 meters) according to depth.

[0003] The current monitoring method for heavy metal concentrations in sediment soil mainly involves experimenters taking samples on site and bringing soil samples back to the laboratory for testing. During the entire testing and analysis process, 60% of the analysis errors come from the sample pretreatment method. The current sediment soil sample pretreatment process requires a lot of manual work and cannot be fully automated. During the mixing and grinding of the samples, a large number of operating steps are required to process the samples, which consumes a lot of manpower and material resources and is inefficient. During this process, the sample quality cannot be controlled, resulting in uneven samples. The reduced samples affect the quality of the sediment soil powder and also affect the subsequent testing time. Summary of the invention
