Embodiment

[0068] like figure 1 As shown, the blast furnace charge particle size monitoring system is set on-site imaging equipment 1, lighting source 2, on-site control box 3, and industrial computer 4, display device 5, indoor control box 6, signal converter 7 and Sound and light alarm device 8.

[0069] like Figure 2~3 As shown, the imaging device 1 and the lighting source 2 are arranged above the blast furnace charge conveying equipment; the blast furnace charge is transported to the blast furnace furnace by a conveyor belt, the imaging device 1 is arranged directly above the conveyor belt, and the lighting source 2 is below the imaging device. Set opposite to each other at 0.4m, the inclination angle is 45°, that is, the luminous angle is 45°; specifically, the lighting source 2 is HQ-SD-W400F floodlight, which satisfies the luminous flux of 40000±5% LM, and the color temperature is 5500 ~ 6000K requirements.

[0070] Since the width of the conveyor belt is 1.6m, the imaging dev...

Abstract

The invention discloses a blast furnace burden particle size monitoring system and a particle size distributed data on-line analysis method. Imaging equipment of the system comprises at least one industrial video camera. Lighting sources are obliquely arranged downwards in the opposite directions at the positions lower than the imaging equipment by 0.4-0.5m so that low-angle lighting can be realized. The luminous flux is 40000+/-5%LM, the color temperature is 5500-6000K, and accordingly field images can be collected clearly. By matching the particle size distributed data on-line analysis method, the images collected at site are sequentially subjected to denoising, balancing, smoothing, reinforcement, sharpening, self-adaption threshold value binaryzation and corrosion and dilation operation, so that the particle size and lump number information of the burden fed into a blast furnace is obtained. The monitoring system is adopted to be matched with the image analysis method so that particle size measurement can be realized, and the accuracy and speed are high. The particle size and lump number information and other information are automatically acquired in an online mode in real time, the varieties of materials are matched automatically, and manpower and material resources are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of on-line video monitoring analysis, in particular to a blast furnace charge particle size monitoring system and an online analysis method for distribution data. Background technique [0002] In the blast furnace ironmaking production process in the metallurgical industry, the blast furnace charge, especially sinter and coke, needs to be analyzed physically and chemically before entering the furnace. Among them, the distribution of charge particle size is a very important parameter. According to the blast furnace smelting process, there are strict requirements on the charge, for example, the particle size of the charge should be uniform, the particle size of the charge should be small, the powder in the charge should be screened out, and the content of harmful impurities in the charge should be small. Raw materials of different particle sizes are loaded into the blast furnace, and the charge will have a fi...
