Method and system for detecting paste blockage degree of trolley grate bars of sintering machine

Abstract

The invention discloses a method for detecting the paste blockage degree of trolley grate bars of a sintering machine. The method comprises the following steps: acquiring initial complete images of all rows of grate bars on a trolley of the sintering machine; performing first image preprocessing on the initial complete images of all rows of grate bars to obtain binary images of all rows of gratebars; performing second image preprocessing on the binary images of all the grate bars to obtain gap images of all the grate bars; based on the binary images and the gap images as well as logic operation, obtaining a paste blockage object image; and based on the ratio of the area of the paste blockage object to the area of the gap image, obtaining the paste blockage degree of the grate bars. According to the method, the pasting and blocking proportion condition of the grate bars can be detected very conveniently and accurately, then the paste blockage degree condition of the grate bars is mastered, the missing positions of the grate bars with high paste blockage degree can be positioned, then fault diagnosis and the like are conducted, and corresponding maintenance measures are taken.

Description

technical field [0001] The present application relates to the technical field of sintering machines, in particular to a method and system for detecting sticking degree of trolley grates of sintering machines. Background technique [0002] Sintering is a process in which various powdery iron-containing raw materials are mixed with an appropriate amount of fuel, solvent and water, mixed and pelletized, and then the materials undergo a series of physical and chemical changes on the sintering equipment, and the mineral powder particles are bonded into blocks. The sintering operation is the central link of sintering production, which includes the main processes such as cloth distribution, ignition and sintering. The key equipment in the sintering operation is the sintering machine. Please refer to figure 1 , figure 1 It is a structural schematic diagram of a sintering machine in the prior art. [0003] Such as figure 1 As shown, the sintering machine includes trolley 101, hea...

AI Technical Summary

Problems solved by technology

The inclination of the grate is affected by the wear and loss of the grate. When the inclination of the grate is excessive, the grate will not be stuck on the trolley body, resulting in a large area of ​​falling off

[0007] 3) The grate gap is blocked

The sintered ore is blocked in the gap between the grates, and the large-area blockage makes the air permeability of the sintering reaction worse and affects the quality of the sintered ore
