Abstract

The invention discloses a device and a method for synchronously demagnetizing steel wire lining conveyor belt, wherein the demagnetizing device comprises a planar demagnetizer, a planar demagnetizer controlling box and a support frame; a magnetizer is arranged in a magnet exciting coil which is positioned on a magnet exciting board and connected with the planar demagnetizer controlling box; a magnet exciting board shell is arranged on the magnet exciting board to form a cavity body; two ends of the support frame are respectively and fixedly connected with a bracket and the magnet exciting board shell, and the planar demagnetizer is fixed above a descending plane of the conveyor belt. The method comprises the following steps: an iron remover is started after metals in mineral materials are detected by a metal detector, and a signal is input into the first input end of an and gate circuit; a conveyor belt walking signal is transmitted into the second input end of the and gate circuit; the planar demagnetizer controlling box is started by an and gate circuit transmission signal; and the planar demagnetizer is controlled to demagnetize the conveyor belt after the planar demagnetizer controlling box receives a signal emitted from an initial start time-delay interrupter. The invention can entirely demagnetize the steel wire lining conveyor belt and ensures the normal operation of the metal detector.

Description

technical field [0001] The invention relates to a belt conveyor, in particular to a synchronous degaussing device and a degaussing method for a steel wire-lined conveyor belt. Background technique [0002] The belt conveyor for long-distance transportation of particles, powdered iron ore, etc. is a kind of efficient transportation equipment today, and is widely used in metallurgical enterprises, docks, ore storage and other industries. High speed, wide conveyor belt surface and so on. [0003] During the transportation of bulk materials (mineral materials), if they are mixed with metal waste, especially when mixed with long rod-shaped sharp metal objects, it will cause great harm. In bulk bulk materials such as coal, ore, etc., the metals mixed in are basically iron and steel substances. These iron and steel substances are generally mixed in during the process of ore collection and transportation. Basically, they are some Machinery and equipment, parts and components of to...
