Detection method and system for material components of stock bin

Abstract

The invention discloses a method and a system for detecting material components of a stock bin, which are characterized in that a virtual layering method of the stock bin is innovated by acquiring a component content set of warehousing materials at a current moment t detected by a component measuring instrument at a feeding belt weigher for feeding and conveying of K stock bins according to a preset frequency or in real time; according to the method, virtual layers of the stock bins are constructed according to a preset time interval, the content of the s component of the virtual layer Nx of the k stock bin is calculated according to a formula, and then component data of current discharging are obtained according to the corresponding relation between the feeding time and the discharging time, so that the components of the stock bins are mastered in real time. The stock bin can be finely layered according to the requirements of process production, so that the purpose of controlling the properties of discharged materials can be achieved, and data support is provided for the next mixing step; and only one component detector and one belt weigher are used at the feeding belt.

Description

technical field [0001] The invention relates to the technical field of intelligent control, and in particular, to a method and system for detecting material components in a silo. Background technique [0002] In the field of smelting, the mixing ratio of various minerals, the water content, the ratio of fuel and limestone during sintering, etc., have a very high degree of influence on the final product, and it is usually necessary to strictly control the composition ratio of raw materials. [0003] At present, only the latest ingredient detection values ​​are simply used for ingredient calculation. Since the raw material warehouse has a certain storage capacity, the ingredients of the raw material batches being used may not correspond to the latest ingredient detection values. Therefore, when the above situation occurs, the actual raw material composition and the ingredients used in the calculation of the ingredients are deviated, which in turn directly affects the actual ra...

Problems solved by technology

Therefore, when the above situation occurs, there will be a deviation between the actual raw material composition and the ingredients used in the calculation of ingredients, which will directly affect the actual raw material ratio

The method of ingredient calculation is basically the same, but how to accurately locate the final composition of the mixed ore stored in the mixed ore bin due to batch differences and moisture content fluctuations has always been a difficult problem to solve

[0004] At present, it is generally used to manually sample and test the raw material components at the outlet of the silo. The samples are taken once or twice per shift, and then used for the calculation of the proportion of ingredients. This method can only be used when the raw materials are relatively stable; the other The method is to install an online component analyzer on the large belt at the outlet of the mixer after batching to comprehensively detect raw materials, but at this time it can only be used to analyze whether the raw material composition, especially the alkalinity and other indicators, meet the batching requirements, and it is impossible to judge which silo raw material Compositional fluctuations require adjustment, making feedback control difficult
