Abstract

The invention discloses a video generated ball grain-size instrument and a generated ball grain size state detection method therefor. The video generated ball grain-size instrument comprises an image collection system, a data transmission system and a data processing system, wherein the image collection system comprises an imaging device arranged between two LED light sources, and the width of an effective material collected in a balling area is not smaller than 1.4m; the two LED light sources oppositely light at a low angle and carry out light source compensation on the imaging device; and denoising, balancing, smoothing, strengthening, sharpening, adaptive threshold binaryzation and corrosion and expansion operation are sequentially carried out on an original image collected on the spot to obtain the particle size and block number information of furnace charge fed into a blast furnace through coordination with the generated ball grain size state detection method. According to the video generated ball grain-size instrument and the generated ball grain size state detection method therefor, accurate monitoring of the pelletizing quality and state of the balling area of a pelletizer and image processing can be achieved, and an abnormal material can be timely alarmed.

Description

technical field [0001] The invention relates to the technical field of video monitoring and analysis, in particular to a video green pellet size meter and a method for detecting the particle size state of the green pellets. Background technique [0002] With the continuous depletion of resources and the continuous rise of international iron ore prices, the quality of raw materials used in blast furnaces continues to deteriorate. For large-scale blast furnaces, the operation of the blast furnace and the quality of molten iron are closely related to the raw materials. "Seven points to raw materials, three points to operation", it can be said that raw materials play a very important role in the smooth operation and stability of blast furnaces. The pelletizing machine is the equipment that provides pelletized mineral materials for the blast furnace. The pelletizing rate of the pelletizing machine and the proportion of ore materials will directly affect the production quality of ...
