Problems solved by technology

In the past, due to the low degree of automation, the proportion of coal blending was mostly result-oriented, with a single start-stop control or no control, but it had little effect on the dynamic and time-varying working method of coal blending, and Great impact on production efficiency
This not only affects the economic benefits of the port, but also seriously affects the image and reputation of the port due to too many commercial disputes

Abstract

The invention relates to material transportation, and discloses a taking system coal blending control method. A taking system comprises a first taking machine and a second taking machine; the control method comprises the steps that taking flow Q1 of the first taking machine and taking flow Q2 of the second taking machine are calculated; the taking efficiency P1 of the first taking machine is calculated according to the taking flow Q1 of the first taking machine, and the taking efficiency P2 of the second taking machine is calculated according to the taking flow Q2 of the second taking machine; the target efficiency P' is calculated according to the taking efficiency P1 of the first taking machine; and the rotation speed of a cantilever is adjusted according to the target efficiency P' of the first taking machine and the taking efficiency P2 of the second taking machine. By means of the taking system coal blending control method, on the premise that halting motion is avoided, the coal blending proportion is strictly controlled, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to material transportation, in particular to a method for controlling coal blending in a reclaiming system. Background technique [0002] The continuous development of the economic era has promoted the vigorous development of the metallurgical industry and the maritime shipping industry. The increasing throughput of port materials also determines the important role of the reclaimer in the port bulk storage yard. However, with the improvement of various industrial functions and the demand for the workload of the stockyard, the reclaimer must have more intelligent conditions. [0003] The coal blending operation of the reclaimer is mainly based on the quality requirements of the user for coal, selecting more than two kinds of coal with different quality standards, using a certain blending ratio, through the continuous transmission of the belt conveyor and the real-time measurement of the electronic belt scale, the output is suitable...
