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.
