An adaptive cement raw meal batching system and its batching method based on typical working conditions

Abstract

The invention discloses a typical-working-condition-based adaptive cement raw meal batching system and a batching method thereof. The batching system comprises an expert system for judging a working condition, a knowledge base for selecting the optimal proportion adjustment strategy, and an automatic adjusting system for adjusting the proportion; and the batching method comprises the following steps: (1) firstly, building the knowledge base for control rules of typical working conditions in a cement raw meal batching process, wherein the typical working conditions comprise ideal working conditions and special working conditions; (2) judging the working conditions by virtue of the expert system; and (3) adopting different control rules according to different working conditions, automatically selecting the optimal proportion adjustment scheme. The system and the method integrate theoretical calculation and artificial intelligent unique control rules to realize self-adaptation to various work conditions of raw material fluctuation, and thus the components of the raw materials are stable; and the batching requirements under different technological conditions can be met by adopting a plurality of adjustment modes and strategies.

Description

technical field [0001] The invention relates to cement raw meal batching, in particular to an adaptive cement raw meal batching system and a batching method based on typical working conditions. Background technique [0002] At present, the quality control of raw materials in most domestic cement enterprises adopts off-line analysis and adjustment methods. The general process is that the laboratory reports samples to the central control operator every hour, and the operator adjusts the ratio of the four raw materials according to the sample data. The sampler collects a small amount of raw meal samples every minute, and after one hour of accumulation, use the fluorescence analyzer to analyze the mixed samples within one hour, and obtain the content of each oxide and the three rate values ​​of the comprehensive sample: silicic acid rate (silicon rate, SM), alumina rate (aluminum rate, IM), saturation ratio (KH); while the operator adjusts the ratio completely by experience, ac...

Problems solved by technology

However, in general, the composition of raw materials will fluctuate, and the comprehensive sample cannot represent the actual composition of the raw meal well. In addition, the operator adjusts it based on experience instead of strict calculation, so the value of the raw meal rate generally fluctuates greatly.
