A metal detection device for a belt conveyor

Abstract

The invention discloses a metal detecting device for a tape conveyor. The device comprises a metal detecting module for acquiring the size of metal on a tape surface of the tape conveyor, a signal processing module which is connected with the metal detecting module and used for receiving the size of the metal from the metal detecting module as well as sending a shutdown signal and an alarming signal when the metal size is more than the preset threshold, a tape conveyor control module which is connected with the signal processing module and used for receiving the shutdown signal from the signal processing module and controlling the tape conveyor to shut down according to the shutdown signal, and an alarming module which is connected with the signal processing module and used for receiving the alarming signal from the signal processing module and sending alarming according to the alarming signal. With the adoption of the device, any dangerous risk on the tape surface of the tape conveyor can be found timely.

Description

technical field [0001] The invention relates to the technical field of belt conveyors, in particular to a metal detection device for belt conveyors. Background technique [0002] In modern high-yield and high-efficiency mines, the belt conveyor is one of the key equipment in the production process, and it is mainly responsible for the transportation of mine coal. Once the belt conveyor breaks down and shuts down, coal mining and excavation will not be able to continue, resulting in serious economic losses. Due to untimely maintenance or cleaning, some irons (such as support materials or irons used for maintenance) often enter the belt conveyor along with the coal. These irons are easy to cause serious damage to the belt, causing the belt conveyor to stop for a long time. Seriously affect production. At present, the belt conveyor is usually equipped with an iron remover, which can remove part of the iron in the coal. However, in the actual production process, it is found th...

Once the belt conveyor fails and shuts down, coal mining and excavation will not be able to continue, causing serious economic losses

Due to untimely maintenance or cleaning, some irons (such as support materials or irons used for maintenance) often enter the belt conveyor along with the coal. These irons are easy to cause serious damage to the belt and cause the belt conveyor to stop for a long time. Seriously affect production

At present, iron separators are usually installed on belt conveyors, which can remove part of the iron in the coal. However, in the actual production process, it is found that for long iron objects such as steel pipes and steel bars, when passing through the iron remover, the steel pipes The front end is sucked up by the iron remover, while the rear end is still buried in the coal flow, forming a "barb"

If the belt conveyor continues to run, the barb may pierce the belt, causing a tearing accident
