On-line sampling system for metallurgical raw materials

Abstract

The invention relates to the field of metallurgy, in particular to sampling of metallurgical raw materials. An on-line sampling system for metallurgical raw materials comprises an ore sampling unit and an ore modulation unit, a coal sampling unit and a coal modulation unit; the coal modulation unit comprises a plurality of splitting machines; the ore sampling unit and the coal sampling unit comprise first, second and third sampling units, wherein the number of the ore sampling unit is 1 to 3, while the raw coal sampling unit is 0 to 2; and the conveying sampling system also comprises an intercommunication unit, each sampling unit is in conveying connection with the intercommunication unit, and the intercommunication unit comprises a plurality of conveyer belts and a plurality of swing chutes for distributing and conveying the raw materials conveyed by different sampling units to the corresponding ore modulation unit or the raw coal modulation unit. The on-line sampling system which is reformed based on the prior ore conveying and sampling systems can screen the coal on line at the same time of finishing conveying and sampling the ore, does not need large amount of manpower, greatly improves the screening efficiency, and reduces the labor intensity.

Description

technical field [0001] The invention relates to the field of metallurgy; in particular, it relates to sampling of metallurgical raw materials. Background technique [0002] Coal and ore are indispensable raw materials for metallurgical enterprises. After the coal mines and mines are transported to various manufacturers by train and ship, they need to be unloaded and inspected. The unloaded raw materials are transported to the warehouse through the conveying mechanism. The sample extraction and preparation for the ore inspection have been completed on the way, but for coal. , the particle size is different, and each enterprise has different physical and chemical index requirements for coal. The first step in sampling inspection must be to distinguish coal according to different sizes of particles. The traditional method is mainly to use low-efficiency artificial means.

Problems solved by technology

After the coal mines and mines are transported to various manufacturers by train and ship, they need to be unloaded and inspected. The unloaded raw materials are transported to the warehouse through the conveying mechanism. The sample extraction and preparation for the ore inspection have been completed on the way, but for coal. , the particle size is different, and each enterprise has different physical and chemical index requirements for coal. The first step in sampling inspection must be to distinguish coal according to different sizes of particles. The traditional method is mainly to use low-efficiency artificial means. The coal is screened, but the coal consumption is very large. As long as it is a slightly large-scale enterprise, it has set up a conveying system for the coal. When the coal is unloaded from the delivery vehicle and ship, there is a conveyor belt to transport the coal to the warehouse. and workshops, and coal grading has become the bottleneck in the coal transportation process. It is more obvious that for hundreds of thousands of tons of coal, a large amount of manpower is required to sieve coal, which is labor-intensive and the working environment is poor.

However, if another set of ore transportation and sampling system is set up, it will not only occupy a large area of ​​land, but also require a huge investment.
