Description

Nondestructive type in-bottle liquid detection equipment

Technical Field

The utility model relates to the field of liquid detection, in particular to nondestructive liquid detection equipment in a bottle.

Background

At present, liquid detection apparatuses for public safety are roughly classified into the following: 1) Based on Raman spectrum identification technology: the raman spectral features of different liquids are different to distinguish the liquid species. However, raman spectroscopic identification techniques cannot detect non-transparent liquid-loaded bottles. 2) Based on the X-ray detection technique, the liquid is irradiated with X-rays, and the safety attribute of the liquid can be accurately judged through the atomic number and the density. However, the X-ray detection technique has ionizing radiation, which causes damage to the human body after long-term use. 3) Based on the dielectric constant discrimination technology, the quasi-static computer tomography technology is adopted, and the inflammability and the explosiveness of the liquid to be detected are judged by measuring the dielectric constant and the conductivity of the liquid to be detected. The method can distinguish flammable and explosive liquid such as liquid explosive, gasoline, acetone, ethanol, tenna water and the like from safe liquid such as water, cola, milk, fruit juice and the like without directly contacting the liquid. However, the determination accuracy of the dielectric constant determination technique is low.
