A sample air-drying device for efficiently air-drying soil samples

Abstract

The invention discloses a sample air-drying device for efficiently air-drying a soil sample. The sample air-drying device mainly comprises a box body, a plurality of air-drying plates, 12-20 holding plates, 12-20 compacting devices, a pressure sensor, a power supply device, a control device and a temperature / humidity sensor; the box body comprises an air-drying box, a control box and a device box,and a bearing frame is arranged inside the air-drying box; the pressure sensor is arranged in the control box and connected with a pressure sensing probe; the power supply device provides a power supply for an used electric appliance; the control device comprises a controller and a touch screen, and the controller is connected with the used electric appliance; the temperature / humidity sensor is arranged in the control box, and a detection probe of the temperature / humidity sensor is positioned in the air-drying box. The sample air-drying device disclosed by the invention is simple in structureand can quickly and efficiently air-dry the soil sample.

Description

technical field [0001] The invention relates to the technical field of sample detection, and specifically designs a sample air-drying device for efficiently air-drying soil samples. Background technique [0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, etc. Organic pollutants mainly include organic pesticides, phenols, cyanides, petroleum, synthetic detergents, and harmful microorganisms brought by urban sewage, sludge, and manure. When there are too many harmful substances in the soil and exceed the self-purification capacity of the soil, the composition, structure and function of the soil will change, the microbial activities will be inhibited, and the harmful substances or their decomposition products will gradually accumulate in...

AI Technical Summary

Problems solved by technology

The amount of samples placed in small enamel trays is small. When the amount of samples required for detection is large, a lot of soil is piled up in small enamel trays and it is difficult to air dry. One sample is placed in different sample trays. When the number of samples is large, it is easy to mix samples.

Use a large enamel dish, which takes up a lot of space; some laboratories spread the samples on clean paper and dry them in the air, which not only takes up a lot of space, but also easily mixes and cross-contaminates the samples; the air-drying box device in the prior art is because Its internal structure is too complicated to make it expensive, and due to the limitation of the sample room, the number of samples to be dried at one time is relatively small
