Description

Technical Field

[0001] The utility model relates to the technical field of soil microwave digestion instruments, and specifically, to a soil microwave digestion instrument. Background Art

[0002] A soil microwave digestion instrument is an instrument used to analyze the content of metal elements in soil. It is mainly used to eliminate interfering substances such as organic matter and oxides in the soil, so as to make the analysis results more accurate. The working principle of this equipment is to heat the sample through high-frequency microwave energy, so that the metal elements in the sample are excited and transition to a high energy level. As the microwave energy continues to be transmitted, the metal elements will spontaneously return to the low energy level and release photons with specific wavelengths. By measuring the intensity and frequency of these photons, the types and contents of metal elements in the soil can be determined. Compared with traditional chemical analysis methods, the microwave digestion method has the advantages of fast analysis speed, low analysis cost, continuous and automated operation, simple sample preparation process, and effective elimination of various biological, physical, and chemical interferences.

[0003] In the existing soil microwave digestion instrument, a rotating plate is provided inside, which can drive the sampling tube inside the rotating plate to rotate, so that the soil inside the sampling tube is heated evenly. However, the high-frequency microwave energy contacted by the sampling tube on the side close to the central axis of the rotating plate is lower than the high-frequency microwave energy contacted by the outside of the sampling tube, resulting in a deviation in the heating uniformity of the soil on both sides of the sampling tube. In order to ensure the uniformity of soil heating, it is necessary to extend the duration of soil microwave heating. At this time, there is still a temperature difference between the two sides of the sampling tube, and it also increases the loss of electric power resources and affects the accuracy of soil detection. For this reason, a soil microwave digestion instrument is proposed. While the sampling tube revolves around the vertical center line of the upper plate as the central axis, the sampling tube rotates by itself to solve the above problems. Content of the Utility Model
