Pretreatment device for soil detection

Abstract

The invention discloses a pretreatment device for soil detection, which comprises a drying and grinding device, a cleaning device and a conveying and screening device connected between the drying andgrinding device and the cleaning device, wherein the drying and grinding device can dry, grind and filter soil; the soil meeting a particle size condition drop into a collection box for collection; grinding balls and gravel are conveyed and screened into the cleaning device by the conveying and screening device for cleaning; and the use of the grinding balls next time is facilitated. The pretreatment device can perform pretreatment, such as drying, grinding and screening, on the soil before analysis; manual participation is reduced; the efficiency is greatly improved; and the labor cost is lowered.

Description

technical field The invention relates to a pretreatment device, in particular to a soil pretreatment device for soil detection. Background technique At present, the detection of soil pollutants needs to be collected on site in advance. There may be some impurities in the collected soil, such as small stones or other impurities. Therefore, the collected soil needs to be pre-treated, and the collected soil needs to be air-dried to pick out impurities and crush Grind and sieve to make the final particle size of the dried soil less than 100 mesh. At present, this kind of pretreatment generally adopts manual treatment. It takes a lot of time to manually select stones, and then place them in a natural environment to air dry. soil, followed by soil composition analysis. The above needs a relatively long time, resulting in a relatively long cycle for each soil composition analysis, and requires a lot of manual participation, which is time-consuming and laborious, taking up a lot o...
