Description

Automatic measuring device for true density of radioactive metal ingot

Technical Field

Background

Currently, the tradition is generally based on the determination of the true density of radioactive ingots by liquid displacement, photoelectric measurement and gas displacement.

The liquid displacement method (dipping method) is to reversely deduce the product density by measuring a liquid density curve by using the archimedes principle. Because the surface of the radioactive metal ingot to be measured is rough, the liquid is difficult to completely immerse the surface to be measured by adopting an immersion method, and the accuracy of the measured volume is difficult to ensure. Meanwhile, the metal ingot has irradiation characteristics, so that the damage to operators in an irradiation environment is large, the post-treatment of the measured liquid is complex, and the use cost of a user is increased. And the degree of automation is low, needs manual whole-course cooperation operation, and complex operation. The photogrammetry is susceptible to environmental and light source intensity. The traditional gas displacement method generally only can detect one sample at a time, the average measurement time is 10-30min, the detection efficiency is low, and personnel cannot really leave the site, so that the labor can not be effectively saved.

According to the traditional method, when the operator needs to manually open the test bin and the constant temperature area and weigh samples, the operator needs to contact the material cup, so that the temperature of the material cup and the temperature of the test bin are changed, the measurement accuracy is affected, and the detection efficiency can be reduced only by prolonging the constant temperature time to compensate. The bottleneck is that a plurality of devices are required to be adopted for simultaneous detection, so that the equipment investment is increased, the labor intensity of personnel is high, the measurement efficiency is low, the test precision is low, and the data summarization is difficult.
