Description

Electromagnetic iron remover

Technical Field

The utility model relates to an electromagnetic iron remover for removing iron in the mine of coal mine.

Background

An iron remover is generally arranged on a coal conveying line of a mine of a coal mine and used for removing iron objects scattered in coal, and generally comprises a bracket, an electromagnetic system and a conveying system; the bracket is transversely arranged above a conveying belt (the conveying belt conveys and transports coal) of the coal conveying line, the electromagnetic system is arranged on the bracket and is positioned right above the conveying belt, an electromagnet formed by an electromagnetic coil and an iron core in the electromagnetic system is provided, and the anode or the cathode of the electromagnet faces downwards to attract iron objects in the coal of the conveying belt; the conveying system comprises a driving roller arranged on the support and a conveying belt sleeved on the driving roller, the lower part of the conveying belt is horizontally arranged, the iron object is attached to the conveying belt at the lower part by the magnetic force of the electromagnet on the iron object, and the conveying belt drives the iron object to transversely move so that the iron object is far away from the magnetic field and falls into the collecting box at one side of the conveying belt.

It will be readily appreciated that ferrous objects fall when traversing to a lateral position where their weight is able to overcome the magnetic force, such that ferrous objects with greater and irregular weights (e.g. elongated objects) fall closer to the conveyor belt (or electromagnet), while ferrous objects with lesser and regular weights need to fall far enough away from the conveyor belt to be able to do so. Thus, if it is desired to disengage ferrous objects with low gravity from the conveyor belt, the transverse dimension of the conveyor system needs to be set sufficiently large, whereas the transverse dimension in the mine is usually small, which results in ferrous objects with low gravity (e.g. small screws, small iron blocks) always following the conveyor belt or falling into unpredictable transverse positions due to fluctuations in the speed of the conveyor belt.
