Powder sample impurity analyzer

Abstract

The invention discloses a powder sample impurity analyzer, which comprises a charging and discharging device and a tiling and cleaning device, wherein the charging and discharging device comprises a funnel arranged at the upper part of one end of a spreading platform, an intermittent feeding mechanism and a discharging slope hopper; the tiling and cleaning device comprises a tiling scraper for tiling forwards and then recovering powder and a cleaning scraper; the tiling scraper and the cleaning scraper are vertically arranged from front to back and are hoisted on a movable rod which is overhung at the upper part of the spreading platform by using an elastic element; the movable rod is arranged on a nut seat; the nut seat is screwed on a lead screw arranged outside the spreading platform; the front and back strokes of the tiling scraper and the cleaning scraper are greater than the front end and the back end of the spreading platform; the bottom ends of the tiling scraper and the cleaning scraper are lower than the spreading platform on the front and back maximum strokes; a CCD camera for photographing the tiled powder downwards is arranged at the upper part of the spreading platform; and the CCD camera is connected with a display processing terminal through a data transmission line. The powder sample impurity analyzer is high in automation degree, high in impurity identification accuracy rate, small in volume, easy to install and simple in operation.

Description

technical field [0001] The invention relates to the field of powder impurity detection and analysis, in particular to a powder sample impurity analyzer. Background technique [0002] With the advancement of science and technology in materials and related industries, powder, as a common industrial raw material, is continuously expanding its application range. People have also put forward increasingly stringent requirements for the purity of powder. At present, there are many analyzes on the quality of powder materials. It is all done manually by manually scraping and flattening the powder and then identifying it with the naked eye. Due to various personal factors such as visual fatigue, the manual detection efficiency is low and the analysis is inaccurate, especially for micro-nano granular powders. analysis is even more difficult. [0003] Manual detection is not only low in accuracy, but also high in labor costs, and powder flying into the air is likely to cause harm to hu...
