Abstract

This invention discloses pulse fast heat neutron prompt gamma cement material component online detecting system, it is aimed at status that need to online detecting cement material chemical components. It includes neutron generator, slowing down body, gamma ray detector, and complex shield safeguard system. Conveying belt crosses over the safeguard system, cement material need to be detected is on the belt, the slowing down body, neutron generator are fixed in the system and below the belt, two or more than two gamma ray detectors are fixed in the system and above the material, it is connected to digital amplifier systemthrough transmission line, the system, data getting system, data analysis system and data display system are in turn connected, so it can detect chemical components of the cement material and provide information for feed proportioning system to improve cement quality.

Description

technical field [0001] The utility model relates to an on-line detection device, in particular to a detection device capable of on-line detection of the composition of cement raw materials transported on a belt conveyor, in particular to a detection device based on pulsed fast thermal neutron prompt gamma (γ) ray Analytical technology of cement material composition online detection system. Background technique [0002] As we all know, the quality of cement is closely related to the composition of raw materials. In order to ensure the qualified rate of cement, the raw materials must be strictly controlled and adjusted in a timely manner. The station provides the necessary information in a timely manner. At present, most of the commonly used methods are sampling offline analysis. This method has less sampling, poor real-time performance, and poor representativeness. It cannot feed back the information of cement raw materials in time, resulting in information lag. It is an aft...
