REMOVING DEVICE FOR ATTACHED MATTER OF CHUTE}

The present invention relates to a fixture removal apparatus for a chute, and more particularly, to a chute fixture removal apparatus for automatically removing a deposit attached to an inside of a chute connected to a belt conveyor to improve production efficiency.

In general, a chute for a belt conveyor is installed between an upper belt conveyor and a lower belt conveyor in a transfer process of an iron mill, and is used as a vertical moving passage of a shipment.

The shipment includes ore powder or powdered coal which is coal powder, or a blended material obtained by mixing the powder and powdered coal.

The chute is a vertically elongated tunnel shape which prevents the shipment from being discharged to the outside, while inducing the shipment onto the belt conveyor of the next stage.

The powdery transports that move along the belt conveyor and chute are strongly caking, and when moisture is added, the adhesion increases even more, so that a deposit is formed on the wall of the chute.

Therefore, the workers check the inside of the chute from time to time to perform periodic cleaning work, but if a lot of stuck in the chute is formed, the production line is stopped, using a hand tool to remove the stuck.

The technical structure described above is a background technique for assisting the understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.

The operator stops the production line to remove the deposits accumulated in the chute and lays down the bottom of the chute in order to remove the sediment using the iron skewer or air breaker, which increases the risk of safety accidents. Productivity is lowered. Therefore, there is a need to improve this.
