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

The invention discloses a method for detecting the inclination angle of grate bars of a trolley of a sintering machine. The method comprises the following steps: acquiring initial complete images of all rows of grate bars on 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 linesof all rows of grate bars; segmenting the images with the clear edge straight lines of all rows of grate bars according to a preset processing strategy to obtain images with a clear edge straight line of a row of grate bars, wherein the images with the clear edge straight lines of the row of grate bars are a set of edge straight line images formed by each grate bar in the row; 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 slope threshold, giving an alarm. According to the method, the inclination angle and the total number of the grate bars can be detected very conveniently and accurately, the inclination and number conditions of the grate bars are mastered, 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 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] like figure 1 As shown, the sintering machine includes trolley 101,...
