Description

[0001] Cleaning device of Conveyor belt [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor belt applied to an industrial field, and more particularly, to a conveyor belt applicable to an industrial field, and more particularly, to a belt conveyor belt for conveying a conveyance (e.g., coke, various industrial wastes, ores, soil, aggregates, iron ore, cement raw materials, To remove the deposit remaining on the surface of the conveyor belt quickly using a high-pressure fluid.

Generally, the conveyor belt is rotated while moving in a state of ENDLESS between the drive pulley and the driven pulley, thereby conveying the article.

However, when the article is conveyed on the surface of the conveying conveyor belt in the past, residual articles of the article often remain, and the conveying conveyor belt is not properly rotated There were many cases.

Accordingly, a number of cleaner apparatuses for cleaning the surface of the belt have been conventionally disclosed.

That is, in the prior art, there has been disclosed a method of removing residual deposits by hitting a conveying conveyor belt, a method of removing residual deposits using a brush, a method of passing through a cleaning tank, and the like. And a method of protecting it with a barrier or a cover so as not to be attached.

However, there is a problem that the surface of the belt is damaged by the cleaner device using the conventional hitting and brushes.

Further, the cleaner apparatus using the washing tank has a disadvantage in that the belt can not be washed in a state in which the article is conveyed.

Conventionally, there is a case where a conveyor belt in which a vent hole is formed is used in manufacturing a conveying conveyor belt. However, there is a structural disadvantage in that the cleaner device of the above-mentioned striking type and brush type can not remove the deposit adhering to the vent hole .
