AI Technical Summary

Technical Problem

During the extraction process, the dioxin extraction device in the existing soil can easily cause soil samples to adhere to the inner wall of the container, and large-grained soil is not easy to mix with the extract, resulting in poor extraction effect.

Method used

An extraction device is designed that includes a heating part, a partition part, a collection part and a grinding part. Through the design of the separation cylinder and the grinding part, the soil sample is prevented from directly contacting the inner wall of the extraction cylinder, and the large particles of soil are reduced through the grinding process to promote the interaction with the extraction cylinder. Mix the extract thoroughly.

Benefits of technology

It effectively prevents soil samples from adhering to the inner wall of the extraction cylinder, improves the extraction efficiency of dioxin, and ensures easy cleaning and efficient use of the device.

Abstract

The present invention provides a device for extracting dioxins in soil, which relates to the technical field of extraction devices, and comprises: a heating part; a partition part arranged above the heating part; a collecting part arranged outside the partition part; and a grinding part arranged above the partition part; by fixing a fixing frame on the top of an extraction cylinder, a grinding process must be performed when adding a soil sample, thereby avoiding the soil sample from being mixed with large particles, thereby facilitating the extraction process of dioxins, making it easy to use, and solving the problem that in the extraction process, most soil samples are directly put into an extraction solution without being treated, resulting in the internal being mixed with particles, making it difficult to mix with the extraction solution, and thus difficult to perform extraction process.
