Laser thickness measuring device of down-draft sintering material layer

Abstract

The invention discloses a laser thickness measuring device of a down-draft sintering material layer. The device comprises a plurality of counterweight measuring rollers which can continuously roll while the sintering material moves, laser distance measuring meters which can respectively emit towards the top surfaces at the center of the counterweight measuring rollers, and an industrial personal computer (IPC) for processing the data measured by the laser distance measuring meters, wherein, the counterweight measuring rollers are arranged on a support base, and the central lines of the counterweight measuring rollers are perpendicular to the side line of a sintering machine trolley on the same straight line; the laser distance measuring meters are arranged on an upright column at the outer side of the sintering machine, respectively record the distance X between laser heads and measuring points on the corresponding counterweight measuring rollers as well as laser depression angles phi, and send the measured data to the IPC through a serial communication bus or an analog-in data card; and the IPC calculates the thickness value of the material layer. The laser thickness measuring device disclosed by the invention has the advantages of high measuring accuracy, contact-less direct measurement through a measuring head, reduced transmission links, good maintenance environment, and synchronous group control, and good coordination with a roll-type material distributor, and is convenient in installation, and is easy to realize the synchronous group measurement.

Description

technical field [0001] The invention relates to a detection device for the cloth thickness of a sintering machine used in the air suction sintering process of ironmaking. Background technique [0002] In the iron-making suction sintering process, the material thickness of the sintering machine is an important parameter of the sintering process and one of the important indicators of the assessment operation. Due to the lack of suitable detection devices, the operator usually directly inspects it visually, and then according to the thickness of the ignition material layer measured manually , plus the empirical shrinkage of the material layer, adjust the speed of the garden roller distribution machine to change the thickness of the material layer, so the operation lags behind and the material layer is unstable. Affect the block degree, drum rate and desulfurization rate of sintered agglomerates, thereby affecting the blast furnace ironmaking effect and energy consumption. The ...
