Explosion proof gamma-ray detector and mining coal ash analyzer

Abstract

The present invention discloses an explosion proof gamma-ray detector and mining coal ash analyzer, and the explosion proof gamma-ray detector includes explosion proof case and gamma-ray receiver located in the explosion proof case, a through-hole provided with ray transmission window for guiding the gamma-ray from outside the explosion proof case into the gamma-ray receiver is arranged on the gamma-ray explosion proof end cover of the explosion proof case. The explosion proof gamma-ray detector and mining coal ash analyzer of the invention not only comprise explosion proof character and makethe explosion proof case has higher transmission to low energy gamma-ray, which assures normal work and measuring accuracy of the mining coal ash analyzer and can be used for real-time on-line measurement of coal ash in coal mine that satisfies urgent need of coal industry modernization production.

Description

technical field [0001] The invention relates to coal quality detection technology, in particular to an explosion-proof gamma ray detector and a mine coal ash analyzer. Background technique [0002] With the extension of coal mining depth, the cost of coal production is gradually rising. Coal ash content is an important indicator of coal quality, which refers to the mass fraction of high atomic number oxide residues after coal is fully and completely burned at a certain temperature. Coal ash is closely related to the calorific value of coal, and it is also the basic basis for setting the ex-factory price of coal in my country at this stage. Therefore, effectively controlling the ash content of coal is an important means to increase the economic benefits of enterprises. It is necessary to do a good job in coal quality control and measure the ash content in coal. [0003] At present, coal ash analyzers based on the principle of γ-ray transmission are widely used to detect coa...

Problems solved by technology

[0006] The purpose of the present invention is to provide an explosion-proof gamma-ray detector and a mine coal ash meter, which solves the problem that the explosion-proof shell of the explosion-proof gamma-ray detector in the coal ash meter greatly attenuates low-energy gamma rays when the existing coal ash meter is applied underground The problem is to realize that the explosion-proof γ-ray detector has high permeability to low-energy γ-rays, and the mine coal ash analyzer can be applied to the underground environment of coal mines.
