Trolley grate inclination angle detection method and system of sintering machine

Abstract

The invention discloses a trolley grate inclination angle detection method of a sintering machine. The method comprises the following steps: acquiring initial complete images of all rows of grate barson the trolley of the sintering machine; carrying out image preprocessing on the initial complete images of all rows of grate bars to obtain images with clear edge straight lines of all rows of gratebars; segmenting the images with the clear edge straight lines of all rows of grate bars according to a preset processing strategy to obtain an image with a clear edge straight line of a row of gratebars; for the edge straight line image formed by each grate bar, obtaining the slope of the edge straight line; and when the slope of the edge straight line is greater than or equal to a preset slopethreshold, giving an alarm. According to the method, the inclination angle of the grate bar can be detected very conveniently and accurately, the inclination condition of the grate bar can be mastered, the grate bar with an overlarge inclination angle can be positioned, then fault diagnosis and the like are carried out, 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 the inclination angle of trolley grates of a sintering machine. 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 put on the sintering equipment to cause a series of physical and chemical changes in the materials, 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, and 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 includ...

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 able to 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 gas permeability of the sintering reaction worse and affects the quality of the sintered ore
