Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sample detection, and particularly relates to a high-throughput fertilizer production sample detection device. BACKGROUND

[0002] With the increasing demand for precise control of fertilizer quality in modern agriculture, high-throughput fertilizer detection technology has become a key to improving production efficiency and product compliance. The existing high-throughput fertilizer production sample detection device can simultaneously realize rapid detection of more than 20 indicators such as nitrogen, phosphorus, potassium, organic matter, heavy metals and microbial activity in fertilizers through the integration of multi-channel parallel detection technology, automatic sample pretreatment system and intelligent data analysis algorithm. The detection efficiency is improved by more than 10 times (such as the detection period of chloride ions is shortened to 15 minutes per sample) compared with the traditional method, and the detection accuracy meets the national standard (error ≤0.5%). Through multi-parameter integrated detection and expert decision system, the device can automatically generate fertilization recommendations and risk assessment reports, and support uploading of detection data to a supervision platform to realize whole-process traceability management.

[0003] In the prior art, the following defects still exist: Sample homogenization and stability conflict: The existing device usually requires that the sample to be detected be pretreated to a homogeneous state and a specified temperature state. However, under the influence of gravity and environmental temperature during sample transfer to the detection cabin and waiting for detection, high-density components (such as heavy metal particles and incompletely dissolved nutrient compounds) are prone to sedimentation, resulting in uneven distribution of sample components and inaccurate sample detection temperature, which significantly reduces the repeatability and accuracy of the detection results and affects the accurate evaluation of fertilizer quality. Stirring module cleaning and efficiency conflict: In order to meet the homogenization requirement, some devices are equipped with a stirring module to realize online mixing of the sample. However, the stirring mechanism is located in a closed detection cabin, which makes it very difficult to clean the residual material after detection. At present, manual cleaning can only be performed by disassembling the stirring assembly, which takes a long time for single maintenance. In the context of batch production, this inefficient cleaning method will seriously affect the efficiency of continuous detection, and even cause interruption of the detection process, affecting the entire production schedule.

[0004] Therefore, it is necessary to invent a high-throughput fertilizer production sample detection device to solve the above problems, which can realize timely detection after sample pretreatment and convenient internal cleaning to improve detection efficiency. SUMMARY
