Analytical equipment for detecting particle size and/or particle form

Abstract

The invention provides analytical equipment for detecting the particle size and / or the particle form. The analytical equipment comprises a sample inlet device (1), a counting device (2), a dispersing system (3), a light source (4), an imaging system (5) and an image processing system (6), wherein the sample inlet system (1) is used for loading test samples and conveying the test samples to the dispersing system (3), the counting device is used for recording the number of the test samples, the dispersing system (3) is used for allowing the test samples to pass through in the falling process to enter a test region, the light source (4) is used for providing an irradiation light source, the imaging system (5) is used for collecting dynamic image information of the test samples and transmitting the dynamic image information to the image processing system (6), and the image processing system (6) is used for displaying dynamic images of the test samples and treating and outputting the particle size and / or particle form data of the test samples. The analytical equipment has the advantages that the defects in the aspects of detection speed, data reliability, operation convenience and the like of the exiting equipment are overcome, the automatic operation is easily realized, and in addition, the work efficiency can be obviously improved.

Description

technical field [0001] The invention relates to the technical field of nuclear reactor engineering, in particular to an analysis device for detecting the particle size and shape of powder and particles in the manufacture of high-temperature gas-cooled reactor fuel elements. Background technique [0002] The ceramic fuel element used in my country's pebble bed high-temperature gas-cooled reactor has a diameter of 60mm and a structure of spherical coated particles (TRISO) dispersed in the graphite matrix of the fuel zone. The diameter of the coated fuel particles is about 0.92mm, and its core is uranium dioxide (UO 2 ), thermally deposited three pyrolytic carbon (PyC) layers and one silicon carbide layer on the core, where UO 2 The main functions of the core are: 1. Nuclear fission occurs to generate nuclear energy; 2. Part of the radioactive fission products are retained. The main functions of the loose pyrolytic carbon layer are: 1. Porous, for gaseous fission products, CO...
