Sample drying box for soil detection

Abstract

The invention discloses a soil detection sample drying box, and the box comprises a box body; a heating plate is embedded in the bottom of the box body, a plurality of test tube racks are arranged inthe box body at equal intervals, each test tube rack is internally connected with a test tube in a matched mode, and an airflow channel is formed in the top wall of the box body; a water absorption structure is arranged on the portion, located above the test tubes, of the airflow channel, the two ends of the airflow channel are arranged on the two symmetrical side walls of the box body respectively, a one-way valve is connected to the joint of the airflow channel at one end and the inner wall of the box body in a sealed mode, and an airflow circulation structure is arranged on the same side ofthe heating plate and the one-way valve. The box has the advantages that the drying agent is applied to the interior of the net-shaped structure of the ventilation net, the drying agent has the effect that when air in the box passes through the ventilation net, moisture in the air can be absorbed by the drying agent, the air in the box body is continuously introduced into the ventilation net through the push block under the reciprocating action of evaporated evaporation liquid, and complete drying is achieved.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to a sample drying box for soil detection. Background technique [0002] Soil environment monitoring refers to the determination of environmental quality and its change trend through the determination of representative values ​​of factors affecting soil environmental quality. Usually soil monitoring refers to soil environment monitoring. The steps generally include point sampling, sample preparation, analysis methods, result characterization, Technical content such as data statistics and quality evaluation, among which point sampling and sample preparation are to collect soil, and then transport it to the laboratory for subsequent processing. [0003] During the operation, the water content of the soil sample is generally between the state of air-drying and water saturation. When detecting heavy metal components, the state of water saturation will affect the test results. Aft...
