Method and device for demagnetizing steel wire conveying belt without energy consumption

Abstract

The invention discloses a method and a device for demagnetizing a steel wire conveying belt without energy consumption. The method comprises the following steps of: a) allowing the moving direction of the steel wire conveying belt to get into an alternating magnetic field formed by a demagnetizing plate, wherein the distance between the demagnetizing plate and the steel wire conveying belt can be adjusted; b) adjusting the distance between the demagnetizing plate and the steel wire conveying belt, and measuring the magnetic field intensity on the back surface of the steel wire conveying belt, if the measured value of the magnetic field intensity is more than 200 Gs, the distance is qualified; c) adjusting the distance that the steel wire conveying belt departs from the demagnetizing plate, acquiring a detection signal through a metal detector, inputting the detection signal into an oscillometer, and observing whether interference pulse exists or not and the peak value of interference pulse wave, if a waveform curve is flat, demagnetization is qualified, and when the waveform curve is abnormal, adjusting the current distance until the detection signal is qualified; and d) after adjusting the current distance until the detection signal is qualified, starting a steel wire conveying belt machine set to perform demagnetizing operation, wherein in the process, the metal detector extracts the detection signal to analyze the whole periphery of the conveying belt to judge a demagnetizing effect. The problem about demagnetizing the steel wire conveying belt is solved by the method and the device, and the method and the device have the characteristics of no maintenance, energy conservation and the like.

Description

technical field [0001] The invention relates to transportation machinery, in particular to a method and device for degaussing a steel wire conveyor belt without energy consumption. technical background [0002] Baosteel Majishan Port is one of the ore bulk ports with advanced equipment in the world, and its bulk cargo loading and unloading capacity has reached the world's advanced level; it relies on advanced equipment, one of which is extremely strong carrying capacity and a total length of tens of kilometers Steel wire conveyor belt, although the steel wire conveyor belt has the advantage of carrying capacity. However, the magnetic field corresponding to the powerful electromagnet of the ore iron remover is easily magnetized; its principle is equivalent to that of an old-fashioned tape recorder, and the long and turning steel wire conveyor belt is like the tape of an old-fashioned tape recorder; The "magnetic head" of the continuously running steel wire conveyor belt is l...
