Description

Apparatus for removing alien substances on a belt conveyor The present invention relates to a foreign substance removal device for a belt conveyor, and more specifically, to a foreign substance removal device for a belt conveyor capable of preventing damage to the belt conveyor by removing foreign substances, such as lumps of ore and frozen ore, contained in raw fuel. Generally, a belt conveyor is a device that transports a large volume of materials using a belt supported by multiple rollers, and is primarily used in conveying systems or automation lines. Raw materials such as iron ore used in steel mills, and fuels such as coal used to melt iron ore during blast furnace operations, are unloaded at the dock using a continuous unloading machine and then transported to the steel plant using a belt conveyor. However, during the process of transporting raw fuel via the belt conveyor, foreign substances such as lumps or frozen ore may be mixed in, causing the chute to become clogged or the belt conveyor equipment to be damaged. The background technology of the present invention is disclosed in Korean Registered Patent Publication No. 10-2275918 (published July 12, 2021, Title of Invention: Belt Conveyor Lump Removal Device). FIG. 1 is a perspective view showing a foreign matter removal device for a belt conveyor according to one embodiment of the present invention.
