Description

Technical Field

[0001] This utility model relates to the field of soil and plant sample digestion technology, specifically a rapid soil and plant sample digestion device. Background Technology

[0002] Soil and plant sample digestion refers to the process of decomposing organic and inorganic substances in a sample into soluble ions through heating or microwave energy under the action of acid or other reagents, so as to facilitate subsequent elemental analysis. This process is usually carried out in a sealed container, using high temperature and high pressure conditions to accelerate the reaction, improve digestion efficiency, and reduce reagent consumption and environmental pollution. It is widely used in environmental monitoring, agricultural research, and soil heavy metal detection.

[0003] In the chemical analysis of soil and plant samples, sample digestion is a crucial pretreatment step. Its purpose is to decompose organic and inorganic matter in the sample into soluble ions through the addition of reagents, facilitating subsequent detection of target elements such as heavy metals. Currently, microwave digestion technology is widely used in the digestion of soil and plant samples due to its advantages of high efficiency, speed, and energy saving. Microwave digestion instruments utilize the penetrating power and molecular polarization of microwaves to enable rapid reaction between samples and reagents under high temperature and high pressure conditions, thereby significantly shortening digestion time and improving digestion efficiency.

[0004] However, in practice, the digestion process of soil and plant samples still faces certain technical bottlenecks. Sufficient contact between the sample and reagent is crucial for digestion uniformity and efficiency; therefore, sample agitation is usually necessary to promote reagent penetration and homogeneous reaction. However, current microwave digestion instruments often use fixed or simple support structures for the sample container. During digestion, the sample may shake due to internal reactions or the microwave field. Soil and plant samples, in particular, exhibit uneven particle size and loose texture, creating resistance that can lead to instability within the microwave cavity, affecting digestion uniformity and safety. Therefore, a rapid digestion device for soil and plant samples is proposed to address these issues. Utility Model Content

[0026] In this embodiment, the reinforcement structure includes two bases 9 fixedly connected to the bottom of the microwave digester 1. A support plate 10 is fixedly connected between the two bases 9. An electric slide 11 is fixedly connected to the top of the support plate 10.
