Description

Technical Field

[0001] The utility model belongs to the technical field of raw coal iron removal, and in particular relates to a raw coal iron removal device. Background Art

[0002] Raw coal iron removal is an indispensable process in coal deep processing. The coal directly mined from the mine during coal mining is called raw coal; raw coal iron removal is to remove impurities in the raw coal. Raw coal iron removal devices with a certain degree of automation have appeared in the prior art. When the existing raw coal iron removal devices are in use, magnets are used to attract metal impurities in the raw coal. This will result in the metal impurities being unable to fall from the surface of the magnet without stopping the machine, so they will continue to accumulate on the surface of the magnet. When the accumulation is too much, the magnet will no longer be able to continue to attract the metal impurities in the raw coal, resulting in a greatly reduced iron removal effect. If the machine is shut down for cleaning, time will be wasted, reducing the production efficiency of the raw coal.

[0003] For example, the Chinese patent with publication number CN219291649U authorizes the disclosure of a raw coal iron removal device. The prior art uses a vibration plate to move the material, which generates a lot of noise and reduces the quality of the working environment. Secondly, the electromagnetic plate absorbs metal impurities and needs to be cleaned regularly, which is inconvenient to use. Utility Model Content
