Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of closed-cup flash point testing instruments, and in particular to an automatic closed-cup flash point testing instrument. Background Technology
[0002] Flammable liquids are widely used in industrial production, transportation, and daily life, such as petrochemical products, organic solvents, coatings, and fuels. Closed-cup flash point, as a crucial safety indicator for assessing the fire hazard of flammable liquids, refers to the lowest temperature at which a sample, heated using a specified closed-cup flash point tester, will produce an instantaneous flash when its vapor mixes with the surrounding air and comes into contact with a flame. Accurate determination of the closed-cup flash point is of immeasurable significance for ensuring the safe storage, transportation, and use of related products, and for preventing fires and explosions. In recent years, the rapid development of sensor technology, automation control technology, artificial intelligence technology, and materials science has provided strong technical support for the innovation of automatic closed-cup flash point testing instruments. The emergence of high-precision temperature sensors has enabled temperature measurement accuracy to reach ±0.1℃ or even higher, allowing for real-time and precise monitoring of temperature changes during the testing process. Advanced automated control algorithms and intelligent heating systems can precisely regulate the heating rate, ensuring that the heating process meets standard testing requirements and significantly improving the accuracy and repeatability of test results.
[0003] Currently available closed-cup flash point testing instruments mainly consist of a heating system and a sample cup and stirring system. Most existing automatic closed-cup flash point testing instruments are designed for homogeneous liquid samples and lack effective mechanisms for handling solid particles. When testing pesticide formulations containing solid particles, the primary risk is clogging. The precision structures of the instrument's internal piping, stirring device, and ignition components are easily blocked by larger-diameter solid particles. The nozzle diameter of the ignition device is usually small; if solid particles enter, it may cause ignition failure or abnormal flame, preventing the test from proceeding normally. Clogged sample delivery lines will also affect the accurate measurement of the sample. Uniform distribution can lead to deviations in test results. From the perspective of test accuracy, the presence of solid particles can interfere with the heat and mass transfer processes of the sample. The thermal conductivity of solid particles differs significantly from that of the liquid matrix. During heating, the rate of temperature rise of the liquid around the particles is inconsistent with that of other areas, resulting in uneven heating of the sample. This uneven temperature distribution can cause the flash point phenomenon to occur prematurely or delayed, leading to a deviation of the measured flash point value from the true value. In addition, the mechanical friction generated by solid particles during stirring may cause local overheating, or even generate sparks before reaching the true flash point, resulting in misjudgment and seriously affecting the reliability of the test results.
