Description

TECHNICAL FIELD

[0001] The utility model relates to iron ore mining technical field, specifically, an iron ore mining demagnetizing device. BACKGROUND

[0002] The demagnetizing device in the iron ore mining process is an important equipment, which is mainly used for removing the ferromagnetic impurities in the iron ore to improve the purity and quality of the ore. The common magnetic stone removal device is a magnetic separator. In operation, the ore is uniformly fed into the sorting area of the magnetic separator through the feeding device. Vibration feeding or screw conveying is usually used for feeding. When the ore passes through the magnetic field, the magnetic minerals will be attracted by the magnetic force and adsorbed onto the magnetic drum, while the non-magnetic minerals will continue to move along the conveying path of the equipment. The magnetic minerals are brought to a certain height during the rotation of the drum and finally fall under the action of gravity and centrifugal force, entering the collection port for collection. The non-magnetic minerals are discharged from the equipment. Since the magnetic stone is affected by the magnetic force and the inertia in the magnetic separation process, it will adhere to the surface of the magnetic separation cylinder. Therefore, it is necessary to perform magnetic separation and separation operation on the magnetic stone.

[0003] In the related art, during the use of the magnetic separation device, the magnetic separation cylinder carrying the magnetic stone is moved to the discharging range by setting the magnetic force range of the magnetic separation cylinder, and then the magnetic separation cylinder and the magnetic stone are demagnetized and separated to fall off, thereby being used.

[0004] However, during the use of the magnetic separation device, due to the setting of the magnetic force range, the magnetic stone is affected by the working inertia of the magnetic separation cylinder during the demagnetization process, which easily causes incomplete separation of the magnetic stone, and the dust and dirt adhered to the surface of the magnetic separation cylinder are difficult to remove, affecting the magnetic separation effect of the magnetic separation device.
