Description

APPLICATION FOR DISCHARGING LEADAGED MINERAL}

The present invention relates to an apparatus for discharging the mineral leaked to the bottom of the raw material transport apparatus.

In general, the transfer device of blast furnace raw material (mineral) receives the ore 50 to the chute 10 and discharged to the lower skirt box 11, as shown in Figure 1a and 1b, the skirt box 11 The ore 50 discharged to the blast furnace is transferred to the blast furnace through a conveyor belt 30, which is a conveying apparatus disposed under the skirt box 11.

The conveyor belt 30 is supported by a plurality of feed rollers 22 and is provided with a rotational force by a tail pulley 40 that transmits power by a power supply unit (not shown). The rotation is performed in the state guided by 25. By the rotation of the conveyor belt 30, the ore 50 discharged from the skirt box 11 is mounted on the conveyor belt 30 and transferred to the head side of the blast furnace.

In the case of the conventional conveying apparatus, when the hole 10a is generated in one region of the chute 10 due to wear and / or damage of the chute 10 itself, the mineral 50 passes through the hole 10a. Leak will leave the area of the conveyor belt 30 falls to the transfer device.

In this case, the ore 50a leaked to the lower region of the inner conveyor belt 30 of the conveying apparatus is stacked, and the leaked ore 50a is accumulated in the lower base 21 region of the conveyor belt 30. If it is fixed, or accumulated excessively, it is piled around the feed roller 22 to cause a friction force on the feed roller 22 may cause a failure of the feed device. In other words, the leaked mineral 50a may cause not only damage to the feed roller 22 itself, but also a temporary stop on the conveyor belt 30, and cause an overload of the drive reducer upon restart, thereby causing a breakdown of the feeder. It is becoming a leading cause.

On the other hand, in addition to the damage of the chute 10, when discharged from the chute 10, the shape of the knitting occurs, or the meandering of the conveyor belt 30 itself occurs, ore 50 is the conveyor belt 30 inside the conveying device 30 Sometimes leaking to the bottom of the shape.

Even in this case, as mentioned above, the leaked ore 50a accumulates and adheres to the lower region of the conveyor belt 30, or in the case of being excessively accumulated, may cause a failure of the conveying apparatus.

1C is a photograph showing a state in which the ore 50a leaked to the lower region of the actual conveyor belt 30 is accumulated.

If the leaked ore (50a) is accumulated in this way, in order to remove it, the drive of the conveying device is stopped, the worker directly scrapes off with a shovel, and sprayed with high-pressure water to clean, ore leaked in this way If this builds up, the task itself must be stopped and a lot of manpower must be mobilized to remove the leaked ore.

Furthermore, in order to prevent the leaked ore from sticking, when spraying high pressure water, the sprayed water is scattered inside the conveying apparatus to contaminate the surroundings of the apparatus, or to the corners of the conveying apparatus and / or the peripheral equipment. Other sticking phenomena occur, and there is a problem such as corrosion of the conveying device and / or peripheral equipment by water.

On the other hand, because the restraint of the transport device for cleaning can not be continued for a long time due to the constraints of other processes, the cleaning worker is exposed to safety accidents due to the sudden operation of the transport device.
