Fuzzy matching and ratio value feedback based cement batching system and method

Abstract

The invention relates to a fuzzy matching and ratio value feedback based cement batching system, which comprises a fuzzy matching based batching calculation module and a fuzzy matching based ratio value control module, and is characterized in that the fuzzy matching based batching calculation module extracts a plurality of samples from a raw material in a multipoint sampling mode through a sampling process, detects to determine chemical components of each sample, then calculates a composite material ratio of each sample by a raw material batching rule base according to a multi-rule fuzzy matching method, and finally calculates a raw material ratio according to the composite material ratios of all samples by a homogenizing process; and the fuzzy matching based ratio value control module performs sampling on raw materials, detects the content of each oxide in a discharged raw material sample by an element analyzer so as to calculate a discharge raw material ratio value and acquire the deviation between the discharged raw material ratio valve and an expected ratio value, and then calculates a corrected ratio according to the multi-rule fuzzy matching method by using a ratio adjustment rule base. The system and the method provided by the invention eliminate influences imposed on the material ratio by raw material component fluctuations and raw material moisture fluctuations.

Description

technical field [0001] The invention relates to the fields of industrial automation and data mining, in particular to a cement batching system and method based on fuzzy matching and rate value feedback. Background technique [0002] Raw material batching in cement production is to mix various raw materials such as limestone, iron powder, clay, coal powder and ore slag according to a certain proportion. The batching process in raw meal production has an important impact on the calcination of cement, the quality of clinker, and the consumption of raw materials and fuels. Domestic cement plants mainly adopt the rate value control method in the control process. Cement plants are generally equipped with an automatic control system for the ratio of raw materials, but the function of automatic calculation and feedback control of the batching scale is mostly not put into use, but continues to be controlled manually. There are many methods for calculating raw material ingredients, ...
