Abstract

The application relates to the technical field of detection systems, in particular to a quartz sand impurity rapid detection system, which comprises an image processing unit, which regularly shoots images on a conveying belt and records the images as flow images, and determines a target area corresponding to each flow image based on overlapping parts; an impurity identification unit, which identifies a material contour in the target area, analyzes an impurity type corresponding to the material contour, records the material contour corresponding to the impurity as a target contour, and determines the position of the target contour; and a jet control unit, which analyzes and determines a jet timing of each jet nozzle based on position coordinates when the target contour is identified and labeled, in combination with a conveying speed of the conveying belt; while outputting the jet timing corresponding to the target contour, the jet control unit analyzes shape features of the target contour to obtain a projection area and a thickness measurement value, and adjusts airflow parameters of the jet nozzle in combination with the corresponding related impurity type. The application can effectively distinguish different types of impurities and perform targeted rejection.
