Sintering layer thickness on-line detecting method

Abstract

The present invention discloses a sintering layer thickness on-line detecting method. Two point light sources are arranged at the upper side of a trolley of a sintering machine to enable a flat surface formed by the light rays of the two point light sources vertical to the wall and the bottom of the trolley. In the vertical flat surface, two light rays are gathered on one point of the bottom of the trolley; one of the two light rays is vertical to the bottom of the trolley, and the other one forms an acute angle a wit the bottom of the trolley. Image collecting equipment is arranged above thetrolley to enable an image collecting range bigger than the lighting range of the two point light source on a charge level. Light point distance Lp of the two point light sources projected on the charge level by the image collecting equipment is collected in a computer, images are processed, and the material layer thickness is calculated by a formula H = tga*Li*g. The present invention solves theproblems of equipment loss, large maintaining volume and the like caused by touching measurement, can be suitable to the bed environment of sintering production, and has the advantages of low equipment cost, small volume, easy arrangement, reliable work, convenient use and the like.

Description

technical field [0001] The invention relates to an on-line detection method utilizing computer image detection and processing, in particular to an on-line detection method for the thickness of a pavement layer of a sintering machine. Background technique [0002] Material layer thickness is a key operating parameter in sintering production, and it is also an important index for evaluating the intermediate operation of sintering machine. The material layer thickness and its stability directly affect the output and quality of sintering ore. Realize the online detection of the material layer thickness of the trolley, and can understand the change of the material layer early, and provide reference for adjusting the material layer thickness, sintering machine speed, bellows damper, ignition operation and sintering end point control. [0003] At present, the measurement methods for the thickness of the material layer of the sintering machine mainly include floating plate type, hea...

Problems solved by technology

However, this method has high requirements on the environment and the structure of the measured object, and cannot better adapt to the harsh environment of the sintering site, and the equipment is easily damaged; When the material surface brakes, the pulling force becomes smaller, and a signal is generated, and the height of the material surface is determined according to the height of the weight drop

This method will also affect the measurement results due to the wear and corrosion of the weight, and like the previous invention, there are more mechanical parts, which are easier to damage and require more maintenance.
