A device for quantitative analysis of uranium-containing grade in sandstone core

Abstract

The invention discloses a sandstone core uranium-containing grade quantitative analysis device, which includes a detection box and a crushing box body, the crushing box body is fixedly installed on the upper end surface of the detection box, and a feeding pipe is fixedly installed on the upper end of the crushing box body , the upper end of the feed pipe is fixed with a feed funnel, the side wall of the feed pipe is fixed with a servo motor, the output end of the servo motor runs through the side wall of the feed pipe and is fixed with a connecting shaft , the drive roller is fixedly installed on the connecting shaft, another identical connecting shaft is connected to the inner wall of the feeding pipe in rotation, and a crushing roller is fixedly mounted on the other connecting shaft, and the crushing roller and the driving roller No. 1 transmission gear and No. 2 transmission gear are respectively fixedly installed on the top. The analysis mode of the present invention has short analysis flow, convenient operation, high stability and precision, and can meet the requirements of nuclear safety monitoring.

Description

technical field [0001] The invention relates to the technical field of sandstone uranium analysis technology, in particular to a sandstone core uranium grade quantitative analysis device. Background technique [0002] Clay minerals in sandstone-type uranium deposits are closely related to the precipitation and enrichment of uranium. The types of clay minerals mainly include kaolinite, montmorillonite, illite and some illite-smectite mixed layers. Due to the cumbersome industrial extraction methods, previous studies on the adsorption and enrichment of uranium by clay minerals are less, and most of them are qualitative studies; [0003] In view of the above problems, the patent No. CN103954739B discloses a calculation method for the relationship between clay minerals and uranium mineralization in sandstone-type uranium deposits. The purpose is to quantitatively analyze the relationship between clay minerals and uranium mineralization in sandstone-type uranium deposits. The m...

Problems solved by technology

[0004] However, in the existing process of uranium chemical conversion process, the uranium content in a large number of uranium-containing uranium ore rocks is the necessary data for development and production, which is directly related to the nuclear criticality safety of the process.

When obtaining data on the uranium content in uranium ore rocks, the above-mentioned traditional method is only to perform a single analysis and calculation on the uranium ore particle sample or to conduct a survey on the uranium ore. This analysis method has a long analysis process and stability. Insufficiencies and shortcomings such as insufficient precision and insufficient precision, cannot meet the needs of nuclear safety monitoring
