Online chemical fertilizer quality detection system

Abstract

The invention provides an online chemical fertilizer quatlity detection system which comprises a sample conveying belt, an optical probe, a detection and control unit, a V-shaped baffle and a main server monitoring device, wherein chemical samples are conveyed by virtue of the sample conveying belt; the optical probe is arranged above the sample conveying belt; the V-shaped baffle is assembled at the front end of the lower part of the optical probe; during a process of conveying the chemical samples on the sample conveying belt, the lower sides of the V-shaped baffle and the optical probe are inserted into the chemical samples; the detection and control unit is internally provided with a wireless communication module; the optical probe transmits collected spectrums to the detection and control unit, and the spectrums are subjected to light split and photovoltaic conversion, generated signals are transmitted to the wireless communication module; the main server monitoring device is used for modeling and quantitatively analyzing the signals wirelessly received from the wireless communication module. The online chemical fertilizer quality detection system provided by the invention is convenient, efficient, accurate, relatively low in cost, free from sample damage, free from chemical reagent consumption and free from environmental pollution.

Description

【Technical field】 [0001] The invention relates to the technical field of chemical fertilizer quality detection, in particular to an online chemical fertilizer quality detection system. 【Background technique】 [0002] In my country's current fertilizer management regulations "Fertilizer Registration Measures", fertilizer refers to "used to provide, maintain or improve plant nutrition and soil physical, chemical properties and biological activities, can increase the output of agricultural products, or improve the quality of agricultural products, or enhance plant The quality of chemical fertilizers mainly includes: nitrogen, phosphorus, potassium, magnesium, boron, zinc, etc. and water, as well as toxic and harmful substances such as biurets in the production process of chemical fertilizers. Unqualified fertilizer products will cause serious harm to crops. For example: At present, most of the chemical fertilizers contain three main nutrients: nitrogen, phosphorus, and potassiu...

AI Technical Summary

Problems solved by technology

For example: At present, most of the chemical fertilizers contain three main nutrients: nitrogen, phosphorus, and potassium. Among them, the urea content, that is, the nitrogen content, is the key quality index of fertilizers, and the impurities contained in it, such as biuret, when the content exceeds 1%, will It has adverse effects on the growth of crops, that is, "burning seedlings". Excessive moisture content will cause fertilizer compaction, which is not conducive to storage and transportation

At present, the quality analysis of chemical fertilizers mainly relies on traditional laboratory analysis methods. This method uses many reagents and involves steps such as weighing, dissolving, digesting, distillation, titrating, and calculating, which is time-consuming and laborious; There is a certain degree of danger and will have an impact on the environment

These limitations have affected the production, sales and rational use of chemical fertilizers to a certain extent

In addition, the production and application of chemical fertilizers in our country are heavy on nitrogen and light on phosphorus and potassium, which causes waste of resources, pollutes the environment, and endangers the health of humans, animals and plants. At the same time, the imbalance of nitrogen, phosphorus and potassium cannot meet the nutritional needs of crops for timely growth.
