Embodiment Construction

[0010] In the figure, the neutron generator console 2, the microcomputer multi-channel analyzer 6, and the printer 7 are arranged in the control room, and other components are arranged in the test room. The neutron generator console 2 is connected with the neutron generator 1 via a cable, and it mainly controls the opening and closing of the neutron generator and the state of the neutron output. Set below the neutron generator is the cement sample box 3, which is entered or taken out through the sample box slideway 9, and the BGO probe 4 is placed under the cement sample box to detect neutron radiation produced by elements in the cement raw meal. r-rays, these r-signals are amplified by the main amplifier 5 and transmitted to the microcomputer multi-channel analyzer 6 for detection. The printer 7 is connected with the microcomputer multi-channel analyzer 6 to print the test results at any time. The overall measurement device uses polypropylene plastic particles 8 as a neutron...

Abstract

This invention relates to a cement multi-element analysis device. The neutron multi-element analysis device uses the neutron generator in the D-D reaction as neutron source and emits rapid neutrons of 2.5 Mev. The neutron reacts with the cement element to generate multi-nuclear reaction with different energy radiation gamma rays. The gamma ray detector is to detect the r rays generated by the elements in the cements. The r signals are through main amplifier and are transmitted to the micro machine for monitoring. It uses multi-path gamma spectrum device to test the area of the characteristics gamma ray peak and gives the relative nucleus content through test formula.

Description

technical field [0001] The invention relates to a cement multi-element cement analysis device, which can promptly and accurately analyze the element content in cement raw materials on site. Background technique: [0002] For traditional cement element analysis, chemical analysis in sampling laboratories is often used. This method has poor representativeness due to less sampling, large limitations, and long analysis time. Contents of the invention [0003] The object of the present invention is to provide a complete set of equipment for neutron cement multi-element analysis. It can quickly and accurately analyze silicon, aluminum, iron, calcium, and magnesium elements in cement raw materials, and at the same time guide the nucleus to weigh the ingredients. [0004] The working principle of the neutron cement multi-element analyzer: use the neutron generator of the D-D reaction as the neutron source, radiate 2.5Mev fast neutrons, and the output is 10 6 n / s. The interacti...
