A mine intelligent iron removal system and iron removal method

Abstract

The invention provides a mine intelligent iron removal system and an iron removal method. When the metal detector detects that a metal object passes through the feeding belt, the metal detector sendsan iron arrival signal to a controller; the controller controls an iron removal mechanism to accelerate firstly; when the speed is increased to be the same as that of the feeding belt, materials are grabbed; at the moment, the iron removal mechanism and the feeding belt are relatively static; the problem that the metal object cannot be grabbed since the feeding belt and the iron removal mechanismmove in the material grabbing process of the iron removal mechanism. Moreover, due to the fact that a traditional magnetic iron removal principle is not adopted, non-ferromagnetic metal or weakly magnetic metal such as high manganese steel, alloy steel and stainless steel can be effectively removed, and metal objects on the middle lower portion and the lower portion of a material layer of the beltconveyor and large metal objects on the middle portion and the lower portion of the material layer of the belt conveyor can be removed. The adaptability to metal objects is high, and the problems offrequent shutdown and manual picking-out of the belt conveyor due to incomplete iron removal of a traditional magnetic iron remover are solved.

Description

Technical field [0001] The invention belongs to the technical field of mine crushing, and specifically relates to an intelligent iron removing system and a method for removing iron from a mine. Background technique [0002] Metals of different sizes and forms are always mixed in the mining, shoveling, transportation and processing of ore. In the process of ore crushing, metal objects will have harmful effects on the crushing equipment and must be removed. At present, the commonly used method is to use magnetic principle iron remover to suck up and remove ferromagnetic metal objects. The traditional iron separators currently used in mines are divided into permanent magnetic separators and electromagnetic separators. The principle of iron removal is to absorb and remove ferromagnetic metals through the new attraction of the magnetic field generated by them. However, traditional iron separators are difficult to remove the following metal objects: 1) high manganese steel, alloy stee...

AI Technical Summary

Problems solved by technology

However, the traditional iron remover is difficult to remove the following metal objects: 1) high manganese steel, alloy steel, stainless steel and other non-ferromagnetic metals or weakly magnetic metals; 2) metal objects in the middle and lower parts of the belt conveyor material layer; 3) Large metal objects in the middle and lower parts of the material layer of the belt conveyor

If this part of the metal iron remover cannot be removed, it must be alarmed by the metal detector at the rear, the belt conveyor is stopped, and manual detection is time-consuming and laborious, and the workload is heavy, which affects normal operation and production.
