Embodiment Construction

[0018] The main purpose of the mine automatic coal blending system is to control the amount of coal fed by multiple coal feeders in proportion, and then transport it to the metering hopper through the same belt conveyor, and then unload it to the skip after being weighed by the metering hopper 6 , and then lifted to the surface coal bunker through the main shaft hoist. During this series of reloading and lifting processes, raw coals of different coal qualities are evenly blended according to the set ratio to meet the needs of different customers and maximize the mine's benefits. The underground automatic coal blending system of this mine can realize automatic coal blending of raw coal with different coal qualities while loading in the main shaft.

[0019] design principle

[0020] Usually, the raw coal from different mining areas is transported to the main shaft for loading through multiple main transport belt conveyors, and put into two or more coal bunkers above. There is ...

Abstract

The invention discloses a mine underground automatic coal mixing system which can realize transferring a coal mixing process to the underground, realizes a coal mixing process while a metering hopperloads coal, reduces a special coal mixing process on the ground, is higher in proportioning precision in comparison with ground coal mixing, and realizes mixed coal outside a well mouth. According tothe following technical scheme adopted by the invention, two or more coal bins are arranged above a main well loading region, the bottom of each coal bin is equipped with a coal feeder, each coal feeder is connected with a frequency converter, and the frequency converter is connected to an upper computer through a communication cable; an adhesive tape conveyor used for coal unloading and transferring of the coal bins is positioned below the coal bins; and the metering hopper is mounted below one side of the adhesive tape conveyor.

Description

technical field [0001] The invention relates to an underground automatic coal blending system. Background technique [0002] Mine usually has multiple mining areas, and the coal quality of different mining areas is quite different in terms of sulfur content, ash content and calorific value. If it is sold separately, it cannot meet the diverse needs of customers, and the price will be greatly affected. In order to maximize the economic benefits of the mine, coal blending in different proportions is required during sales. [0003] At present, the usual coal blending work is mainly carried out in the ground coal yard. Forklifts and other equipment are used for manual coal blending. The coal blending efficiency is low and the blending ratio is not accurate and uniform. An additional coal blending process is added to the sales process, which increases the sales cost. [0004] In view of this situation, we researched and designed a system to realize the loading system in the mai...
