Abstract

The invention discloses a soil sample treatment device based on heavy metal detection, and relates to the technical field of soil detection. The device comprises a heating barrel and a heating bowl fixed on the heating barrel; a water inlet is formed in the bottom side surface of the heating barrel, and an L-shaped overflow pipe is fixed in the heating barrel; an electric heating unit and a temperature sensor are further arranged in the heating barrel, and the electric heating unit and the temperature sensor are both connected with a controller, and the electric heating unit and the temperature sensor are both connected with a power supply; an outer edge is arranged on the peripheral side of the heating bowl, and a plurality of fixing flanges are arranged on the edge of the outer edge andare in threaded connection with fixing screws; and blind holes matched with the fixing screws in position are formed in the outer side wall of the heating barrel. While drying is conducted through thecombined use of the heating bowl, the heating barrel, an end cover and a moisture absorption device, the problem that secondary cross contamination is likely to be caused in the existing drying process is solved.

Description

technical field [0001] The invention belongs to the technical field of soil detection, and in particular relates to a soil sample processing device and processing method based on heavy metal detection. Background technique [0002] The composition of soil is very complex. Generally speaking, it is composed of three phases of solid, liquid and gas such as minerals, organic matter produced by the decomposition of animal and plant residues, water and air. Before the determination of the physical and chemical properties of soil in the laboratory, the soil samples collected in the field must be prepared. The standardized operation of the soil sample preparation process is the guarantee of accurate analysis results. Soil analysis samples collected from the field need to go through six processes of drying, sorting, picking, grinding, sieving, and bottling. Drying means that the collected soil samples must remove water as soon as possible. The purpose is that fresh samples are temp...
