一种沉积物中微塑料的提取装置及其提取方法
摘要：
本发明提出的是一种沉积物中微塑料的提取装置及其提取方法，该提取装置的结构包括滤筒、贮液罐、电动机、底座、网筛、传动轴；其中，滤筒安装于贮液罐内，滤筒的上口处有网筛，贮液罐和电动机安装在底座上，贮液罐底部有与滤筒相贯通的排孔；电动机通过转轴与传动轴的一端相接，传动轴的另一端穿过排孔与滤筒的底部相接。本发明的优点：（1）泥质沉积物的分散及样品的洗脱效果明显提高；（2）提高了样品回收率；（3）提取效率明显提高；（4）提取时间缩短；（5）节省人力。
摘要（英）：

A device and method for extracting micro-plastic in settlings are provided. The device includes a filter drum, a liquid storage tank, a motor, a pedestal, a screen sieve and a transmission shaft. The filter drum is mounted in the liquid storage tank. The upper port of the filter drum is provided with the screen sieve. The liquid storage tank and the motor are mounted on the pedestal. The bottom of the liquid storage tank is provided with a drainage hole communicated with the filter drum. The motor is connected to one end of the transmission shaft through a rotating shaft, and the other end of the transmission shaft passes through the drainage hole and is connected to the bottom of the filter drum. The device and the method are advantageous in that (1) dispersion effects of muddy settlings and elution effects of a sample are obviously improved; (2) the recovery rate of the sample is increased, (3) the extraction efficiency is greatly increased, (4) extraction time is shortened and (5) labor is saved.
