Embodiment 1

[0017] Such as figure 1 The combined metal detection device includes a sine wave metal detector 1 and a square wave metal detector 2, the sine wave metal detector 1 and the square wave metal detector 2 are installed above the belt conveyor 6 along the transmission direction of the belt conveyor 6 (The installation sequence of the sine wave metal detector and the square wave metal detector on the belt conveyor can be reversed, and the sine wave detection or the square wave detection first will not affect the iron passing effect), and the belt conveyor 6 passes through the two metal detectors When the material on the belt conveyor 6 passes through the sine wave detector 4, long rod-shaped or magnetic steel-like metals are detected; when passing through the square-wave detector 5, large pieces of weak magnetic steel or alloy steel-like metals are detected.

[0018] The alarm signal output terminal of the sine wave metal detector 1 is connected in series with the alarm signal outp...

Embodiment 2

[0021] The specific detection method is:

[0022] The iron ore is evenly distributed from the hopper to the belt conveyor 6, and the ore is sent to the next process by the belt conveyor 6 at a constant speed through the sine wave detector 4 and the square wave detector 5. If the ore contains long rod-shaped metal or magnetic For steel metal, when passing through the sine wave detector 4, the sine wave metal detector 1 sends out an alarm signal, instructing the operator to check and remove iron pieces near the sine wave detector 4, and at the same time, the belt conveyor control box 3 sends out a stop signal to let the belt conveyor stop working. If the ore contains large pieces of weak magnetic steel or alloy steel objects, the square wave metal detector 2 will send an alarm signal when passing through the square wave detector 5, and notify the operator to check and remove the iron pieces near the square wave detector 5, and at the same time The belt conveyor control box 3 se...

Abstract

The invention discloses a combined metal detection method and device. The combined bank customer service terminal has the advantages that two different detection manners are combined, materials are detected through two metal detectors, and different kinds of objects can be thoroughly removed; the identification rate of the metal detector to the metal objects in ore is increased, and the problems that equipment is damaged and production is affected due to iron is well solved; the device is simple and practicable, safe and environmentally friendly, and wide in application range.

Description

technical field [0001] The invention relates to iron passing detection applied in complex industrial and mining environments such as mines, in particular to a combined metal detection method and device. Background technique [0002] Mining enterprises are easily troubled by excessive iron in the process of ore processing, which often causes damage to equipment, affects production, and causes huge direct economic losses. [0003] Most of the metal detectors currently on the market use continuous sine wave excitation to receive signals to determine whether there is excessive iron. Such damaged mining accessories cannot be effectively detected, causing such objects to enter subsequent production, causing damage to equipment such as crushers and affecting normal production. Contents of the invention [0004] In order to solve the defect that the existing metal detectors cannot effectively detect large pieces of weak magnetic steel objects, solve the impact of iron overhea...
