In the agricultural field, if the content of heavy metals in the soil exceeds the standard, it will not only affect the normal growth of plants, but also endanger the health of humans through the food chain. At the same time, it can also cause serious atmospheric and water pollution problems. Therefore, in the development of modern agriculture, Carrying out treatment of heavy metals in the soil has become an urgent matter, and through the soil heavy metal quick-detection instrument to detect the soil, we can know what pollutants are currently contaminated by the soil we cultivate and how deep the pollution is. Soil testing and restoration provides scientific data and technical support. Hot medium is put into the jacket for drying, heat exchange is done between the inner wall and materials. After the materials absorb heat, water is evaporated. The evaporated moisture and other gas is exhausted from vacuum pipe by vacuum pump. In the tank it is vacuum state and the rotary of tank makes the materials overturn continuously, so the drying speed is fast and drying intensity is increased, and can achieve the purpose of uniform drying. It is a new style dryer that combines mixing and drying together. It can be used together with condenser and vacuum pump. (If do not need to recover solvent, condenser is not needed).

At present, with the continuous and steady progress of soil remediation projects, the application of soil heavy metal quick-tracking instruments has become more and more widespread. Although the use of soil heavy metal quick-tracking instruments is very simple and does not require users to have a very professional technical level, it only needs After simple training, it is possible to operate, but in order to allow the instrument to exert its superior performance, to provide accurate and reliable test data for people, in addition to grasping the correct use of soil heavy metal rapid-measuring instrument, we should also understand some soils. The precautions for the use of heavy metal speedometers are to clarify what things cannot be done.
1. Soil heavy metal quick-detection instrument should avoid high temperature in use In general, soil heavy metal quick-detection instrument has a certain range of use environment, such as the use of temperature is generally -10 °C -50 °C, if the temperature is too high, may cause the instrument components The damage, and the long-term use of soil heavy metal quick tester will cause the instrument temperature is too high, so in order to avoid equipment damage, in this case, the instrument should be measured after a short break.
2. Soil heavy metal rapid tester should avoid falling in order to be able to accurately and quickly determine the content of heavy metals in the soil, the soil heavy metal quick-detection instrument uses a X-ray tube containing, and these sophisticated components are very afraid of severe collision Therefore, in the process of using soil heavy metal quick tester, be sure to avoid falling and avoid violent impact. Although, how to prevent falling and falling is the current direction for the research and improvement of soil heavy metal quick-tracking instruments, we should pay special attention to this issue at this stage.
