Embodiment 1

[0044] In this embodiment, the actual coal blending amount of Inner Mongolia coal is required to be 9%, and its coal blending optimization method comprises the following steps:

[0045] S1: Count the coal blending amount with the highest probability of use among the actual coal blending amounts of the 3 feeding leaks in each group of feeding leaks in each silo, and use the probability according to the "closest matching principle" The highest coal blending amount is classified as 5%, 10% or 15% coal blending amount, and each feeding nozzle in each group of feeding nozzles uses 5%, 10% or 15% coal blending respectively The given frequency of the corresponding disc feeder when measuring;

[0046] S2: if figure 2 As shown, according to the actual coal blending conditions of 1#, 2# and 3# blanking nozzles in the production situation in the next month, the circles corresponding to the 5% gear, 5% gear and 10% gear are respectively adjusted before coal blending. The given frequenc...

Embodiment 2

[0050] In this embodiment, the actual coal blending amount of Inner Mongolia coal is required to be 16%, and its coal blending optimization method comprises the following steps:

[0051] S1: Count the coal blending amount with the highest probability of use among the actual coal blending amounts of the 3 feeding leaks in each group of feeding leaks in each silo, and use the probability according to the "closest matching principle" The highest coal blending amount is classified as 5%, 10% or 15% coal blending amount, and each feeding nozzle in each group of feeding nozzles uses 5%, 10% or 15% coal blending respectively The given frequency of the corresponding disc feeder when measuring;

[0052] S2: if figure 2 As shown, according to the actual coal blending conditions of 1#, 2# and 3# blanking nozzles in the production situation in the next month, before coal blending, the circles corresponding to the 5% gear, 5% gear and 5% gear are respectively adjusted The given frequenc...

Abstract

The invention discloses an optimization method for improving the accuracy of automatic coal blending in large-volume silos, and belongs to the field of automatic instrument program control for coal blending production in large-volume silos in the coking industry. This method is based on the fact that every 3 feeding nozzles share a set of automatic coal blending weighing system, which can better solve the coal blending accuracy caused by the frequent start and stop of the main conveyor belt in the coal blending process, which causes a large number of low-accuracy running times to overlap. Falling puzzle. Moreover, the method of the present invention is simple, easy to operate, and has strong reliability. After use, the quality of mixed coal is significantly improved, which can effectively improve the accuracy of automatic coal blending and the qualified rate of mixed coal quality in large-volume silos, reduce invalid running time, and improve production efficiency. .

Description

technical field [0001] The invention belongs to the field of automatic instrument program control for coal blending production in large-volume silos in the coking industry, and in particular relates to an optimization method for improving the accuracy of automatic coal blending in large-volume silos. Background technique [0002] During the production of the large-volume silo coal blending system, according to the requirements of the coal blending ratio, the individual coals with different performance indicators stored in each silo are blended in through the automatic coal blending weighing system according to their different coal blending ratios, and mixed into High-quality blended coal that meets the process requirements. [0003] At present, the coal storage capacity of a single large-volume silo is generally 10,000 tons, and there are 6 discharge nozzles at the bottom, which are divided into two rows. Each feeding nozzle is equipped with a set of automatic coal blending...
