The invention belongs to the technical field of blast furnace ironmaking and raw material transportation equipment, and particularly relates to an online sampling and waste material recovery device. The method aims to perform the whole processes of sampling, quantitative sampling, material abandoning and the like on line, improve the automation level, reduce the labor intensity of workers, and is not only suitable for blast furnace iron making but also suitable for the related technical fields of raw material transportation and the like.
Background
With the large-scale, high utilization coefficient and low-cost operation of blast furnaces, the coal ratio is continuously improved, the service life of the blast furnace is continuously prolonged, and the quality requirement on raw fuel is continuously improved. Meanwhile, along with the change of ore resources and the development of the domestic pellet technology, the furnace burden structure is also continuously adjusted and optimized. The concentrate technology is the basic and objective requirements of smooth production of the blast furnace, advanced indexes and energy conservation and emission reduction, and the concentrate is used as a basic condition for improving the utilization coefficient. The influence rate of the concentrate technical level on the blast furnace ironmaking technical and economic indexes is as high as 70%, and the influence rate of other factors is lower, such as: the influence rate of the blast furnace operation technology level is 10%, the influence rate of the enterprise management level is 10%, the influence rate of the equipment running state is 5%, and the influence rate of transportation, water and electricity supply, weather changes, the production conditions and links of the upper and lower procedures is 5%. Consequently, the concentrate technology is receiving more and more attention and becomes the basis for carrying out the "reduction" production.
The concentrate technology mainly comprises eight aspects of high, ripe, clean, even, small, stable, little and good. Wherein: the 'high' refers to high grade of the charged ore, the high grade is the core of the concentrate technology, the comprehensive grade of the charged ore of the modern large-scale blast furnace is more than 58%, the comprehensive grade of the charged ore is more than or equal to 61% when a large-proportion pellet charging material structure is adopted, the drum index of the sinter, the pellet and the coke is high, and the drum index of the high-alkalinity sinter is as follows: not less than 78%, coke: more than or equal to 89 percent of M40, less than or equal to 6.0 percent of M10 and less than or equal to 11.5 percent of ash; the clinker rate is that the clinker has certain high-temperature strength, good air permeability, higher reduction rate, proper reflow temperature and a reflow temperature interval, which is beneficial to improving the utilization coefficient of the blast furnace, reducing the fuel ratio and stabilizing the production; the net is that the powder content in the furnace charge is required to be small, the amount of powder entering the furnace charge is reduced, and the powder which is less than or equal to 5mm in the furnace charge is less than 3 percent; the uniform is that the granularity difference between various furnace charges cannot be too large, the furnace charges have proper granularity composition and uniform granularity; "small" means that the particle size of the sinter and pellets should be suitably small; "Stable" means that the chemical composition and physical properties of the raw fuel entering the furnace are stable, and the fluctuation range is as small as possible; "less" means less harmful impurities contained in the raw fuel entering the furnace; "good" means that the metallurgical properties of the iron ore are good. The concentrate mainly depends on the indexes of raw fuels such as sinter, pellet and coke before iron making, wherein the indexes such as high, stable, less, good and small are determined by the iron making process, and the indexes such as mature, clean and even are realized by the iron making process and the iron making process. The clinker rate is controlled through a reasonable furnace burden structure in the iron-making process, at present, high-alkalinity sinter ore is mostly adopted to match with acid pellet ore and partial lump ore, and a feed raw material structure mainly comprising clinker such as sinter ore, pellet ore and the like is adopted, and the clinker rate is more than or equal to 85 percent; the amount of powder entering the furnace is reduced through screening treatment under the groove, and the powder which is less than or equal to 5mm in the furnace charge is less than 3 percent; by adopting a graded charging technology, under the condition of not changing the quality of the raw fuel, the particle size is optimized, the particle size difference is reduced, the uniformity of the particle size is realized, the void ratio of furnace charge is improved, and the air permeability is improved.
