Description of drawings
Fig. 1 is the example structure figure of the utility model X-ray energy spectrum rock core scanner.
Embodiment
Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
Fig. 1 is the example structure figure of the utility model X-ray energy spectrum rock core scanner, and as shown in the figure, the X-ray energy spectrum rock core scanner of present embodiment comprises: the power spectrum that is used to produce the x-ray source 11 of X ray and be used for the Analysis of X ray fluorescence pops one's head in 12; Also comprise: sample motion control platform 13 is used to place core sample and makes the scanning of the X ray that core sample at the uniform velocity produces by x-ray source; Unsteady gas compartment 14 is used to provide the scanning core sample required protective atmosphere environment, and is provided with the window that passes through for the XRF that is produced behind X ray and the x-ray bombardment core sample.
Around measuring the periodic table of elements before the phase during X-ray energy spectrum of element; so the interference of elemental gas needs vacuum environment or has the measurement environment that atmosphere (helium) is protected in the air owing to being subjected to, the unsteady gas compartment 14 of the foregoing description can address this problem well.In addition; the gas compartment 14 that floats also is provided with employing X ray is absorbed three flexible windows 141～143 that ultrathin flexible macromolecular material is seldom made; as shown in the figure; its outgoing, X ray that is respectively applied for x-ray source 11 X ray that produces is to the scanning of core sample and the absorption of 12 pairs of XRF that core sample reflects of power spectrum probe; being arranged on of above-mentioned flexible window guarantees under blanket gas and the atmosphere separation situation; by the miniature deformation realization of window and combining closely of core sample, guaranteed the minimum that influences simultaneously to sample.Blanket gas in the above-mentioned unsteady gas compartment 14 can be a helium etc.
Owing to have rugged problem on the rectangular core sample, be the comparability of the fluorescence data that guarantees to gather continuously automatically, the distance on analyser that x-ray source and power spectrum probe are formed and the core sample between the analyzed sample spot should be able to automatically-controlled continuous within error range.At this demand, the X-ray energy spectrum rock core scanner of present embodiment also is provided with height measuring gauge 15, being fixed on the gas compartment 14 that floats and with power spectrum probe 12 has signal to be connected, it is used to measure self apart from the height between the sampled point of core sample and produce feedback signal control power spectrum probe 12 and move up and down, thus between analyser that x-ray source and power spectrum probe are formed and the sampled point apart from automatically-controlled continuous in the error range that allows.
More than be preferred forms of the present utility model, according to the disclosed content of the utility model, those of ordinary skill in the art can expect some identical, replacement schemes apparently, all should fall into the scope of the utility model protection.
