Abstract

The invention discloses a sample treatment device used before XRD (X-Ray Diffraction) detection. The sample treatment device comprises a grinding device and a tableting device arranged below the grinding device, the grinding device comprises a grinding tank body, a grinding rod, a grinding hammer, a grinding sieve and a taper hopper, the grinding rod, the grinding hammer, the grinding sieve and the taper hopper are sequentially arranged in the grinding tank body from top to bottom, a heating device is arranged on the outer wall of a shell body at the periphery of the grinding sieve; the tableting device comprises a tableting tank body, an XRD sample grinding apparatus, a tableting table, and an elastic shrinkage device arranged in the tableting tank body, a support plate is fixedly connected at the top part of the elastic shrinkage device, a control device used for controlling the elastic shrinkage device to inflate air or deflate is connected on the side part of the elastic shrinkagedevice, and a tableting mechanism used for flattening an XRD sample is arranged on the side part of the tableting table. The grinding device is arranged to grind the XRD sample, the XRD sample is scraped and tableted through the tableting mechanism, the operation is simple, the manual labor is not needed, the obtained XRD sample is flat, the flat XRD sample helps to improve the accuracy of experimental data in the later period, the structure is simple, and the intelligent degree is high.

Description

technical field [0001] The invention relates to an experimental auxiliary equipment, in particular to a sample processing device before XRD detection. Background technique [0002] With the development of the catalytic industry, laboratory testing equipment is becoming more and more advanced. For example, XRD diffractometer is one of the most effective tools for analyzing the crystal form of solid substances such as catalysts in the laboratory by using the principle of infrared light detection to analyze the mineral composition and crystal orientation structure in the substance. Before detection, any powder diffraction technique requires the sample to be very fine powder particles, so that the sample has a sufficient number of grains in the illuminated volume. Only in this way can the condition of obtaining the correct powder diffraction pattern data be met, that is, the orientation of the crystal grains in the illuminated volume of the sample is completely random. Only in...

Problems solved by technology

However, in the existing technology, the operation of the above two steps in the laboratory is still manually grinding the sample and smoothing the sample a little bit into the measuring mold, which is not only time-consuming, but also difficult to guarantee the quality of the grinding and smoothing of the sample. , so that the error of the experimental detection data is large; in addition, it is believed that the operation is also very easy to cause samples to be scattered on the ground, resulting in waste and pollution

And some samples are measured without being completely dry, which will cause irreparable damage to the instrument
