Description

Technical Field

[0001] The utility model relates to the technical field of flash point rapid detection of mixed oil, and specifically relates to a flash point rapid detection device based on mixed oil. Background Technique

[0002] The flash point of mixed oil refers to the lowest temperature at which the volatile components in the mixed oil can form a sufficient mixture in the air to support combustion under specific conditions. This temperature is usually used to evaluate the fire hazard and safety of the liquid. The specific flash point depends on the composition of the mixed oil. Different types of mixed oils have different flash points due to different compositions. The closed cup method is usually more suitable for rapid detection because it can measure the flash point of the oil under controlled conditions and avoid the interference of environmental factors.

[0003] It is not easy to determine the flash point of mixed oil and it is very susceptible to the interference of environmental factors. During the use of general flash point rapid detection devices, gaps are likely to appear between the oil cup and the cover plate. When the heating furnace heats the mixed oil in the oil cup, some heat will be lost through the gaps, and it is very difficult to keep the temperature of the mixed oil stable. There is a deviation between the detected temperature when the flash point appears and the actual flash point temperature. Using the detected temperature as the basis for the safety standard of the mixed oil has a relatively large potential safety hazard. When the detection device heats the mixed oil, the liquid vapor is likely to leak from the gaps to the outside of the oil cup, causing air pollution. If it encounters an open flame and flammable substances, a fire is likely to occur. To solve the above problems, a flash point rapid detection device based on mixed oil is proposed.
