Description

Blending reclaimer with apparatus for preventing blending ore rain infiltration and method for preventing blending ore rain infiltration using the same}

The present invention relates to a blending recrammer, and more particularly, to a blending recrammer equipped with a blending light rainwater blocking device for preventing rainwater from flowing and mixing with a blending light stored in a yard in case of rain, and a blending light rainwater using the same It relates to a method for preventing mixing.

In general, the blending recramer is a device that emits blending light in order to supply the blending light stacked in the yard to the sintering process by mixing multi-brand spectroscopic raw materials.

The blending recramer is disclosed in Publication Patent Publication No. 10-2005-0043448 and Publication Patent Publication No. 10-2007-0008844. The blending recramer is composed of a double bucket wheel unlike a general recramer, and the bucket wheel rotates in the forward and reverse direction to discharge the blending light stacked in the yard. That is, when the blending light is collected through the bucket provided on the bucket wheel, the opening direction of the bucket containing the blending light is changed according to the rotation direction of the bucket wheel.

According to the disclosed literature, the blending recrammer has a driving unit that moves toward the blending light pile piled up in the yard, a wheel unit that rotates and collects the blending light (hereinafter referred to as a 'bucket wheel'), and a bucket wheel to traverse the blending light It is a transversal device that moves in the direction and is divided into approximately three parts. In the blending light dispensing method through the blending reclamer, the two bucket wheels are rotated and operated, and the blending light is emitted with a plurality of buckets provided on the bucket wheels while traversing in the width direction of the blending light stacking file through the traversing device. At this time, the blending light is introduced into the wheel chute provided in the bucket wheel, and the blending light loaded on the belt conveyor disposed below the wheel chute is supplied to the sintering process. In this way, when the blending light is collected from the yard through the blending recrammer, a vast yard space having a maximum width of 45m and a length of about 300m is formed in the yard passed by after being discharged to the blending recrammer. In the state where such a yard space is formed, a problem arises in that rainwater accumulates and is mixed with the blending light during heavy rain or rain, and FIG. 1 shows this problem.

Referring to FIG. 1, in the blending recramer 1, the bucket wheel 10 equipped with a plurality of buckets 12 rotates at a fixed height and at the same time traverses by the harrow 18. The blending ore 25 that has flowed down is collected by the bucket 12 and loaded onto the in-flight belt conveyor 30 to be supplied to the sintering process. At this time, in a state where a vast space is formed in the yard Y according to the collection of the blending light 25, rainwater is not drained early in heavy rain or rain, so the blending light 25 is flowed into the bucket 12 for dispensing and discharged. The blending light 25 and rainwater are mixed. Therefore, there is a problem that equipment trouble is caused by a large amount of bamboo ore and falling ore during transportation, and bamboo ore is mixed in the sintering process, which adversely affects the operation.

On the other hand, in order to prevent rainwater (R) collected in the yard (Y) from flowing into the blending mine (25) in case of rain, a dam is built behind the stacking pile (20) collected using a forklift, but in equipment mobilization Excessive work time is taken until the work is completed, and the work efficiency is reduced because the blending light dispensing work is stopped until the pile forming work is completed.

Then, when the blending light is issued through the blending reclamer 100 equipped with the rainwater mixing blocking device 200 as described above, a specific method for blocking rainwater from mixing with the blending light 25 during heavy rain or rain to be explained as

First, in a state where the belt conveyor 30 of the blending recrammer 100 disposed in the yard Y is in operation, the bucket wheel 10 rotates while the bucket wheel 10 moves transversely, The blending light 25 flowing down by the (harrow) 18 is discharged. That is, the blending light 25 is collected by the bucket 12, loaded on the in-flight belt conveyor 30 through the wheel chute 14, and supplied to the sintering process.

After the bucket wheel 10 traverses and emits the blending light 25, the blending re-cramer 100 advances a predetermined distance toward the stacking pile 20 stacked in the yard Y, thereby discharging the blending light described above. Do it.

A space is formed in the yard Y according to the dispensing operation of the blending light 25 . At this time, a large amount of rainwater (R) is not drained and accumulates on the floor in case of heavy rain or rainy weather in the blending light discharge operation state. Thus, in order to prevent the rainwater R from being mixed with the blending light 25, the rainwater mixture blocking device 200 may be operated. The rainwater mixture blocking device 200 may be automatically operated by detecting rainwater falling during heavy rain or may be remotely controlled by an operator.

Specifically, in heavy rain or rain, the blending light dispensing operation is stopped, and the blocking plate 224 moves inside the bucket wheel 10 according to the operation of the driving unit 230, and the open top of the wheel chute 14 shut down

In this way, the bucket wheel 10 rotates and collects the blending light 25 while the open top of the wheel chute 14 is closed, so that the blending light 25 does not fall into the wheel chute 14 and It goes over the blocked upper end of the wheel chute 14 and falls to the rear side where it is collected. Accordingly, the falling blending light 25 is accumulated and a barrier 250 is formed to block rainwater R from flowing into the stacking pile 20.

The barrier 250 may be formed by performing traversing work once or twice through the bucket wheel 10 in a state in which the wheel chute 14 is closed, but the number of times may vary depending on the working environment.

As described above, when the barrier 250 is formed to block mixing of the rainwater R with the blending light 25, the dispensing operation is performed again after opening the upper part of the wheel chute 14.

As described above, although the present invention has been described by the limited embodiments and drawings, the present invention is not limited thereto, and the technical spirit of the present invention and the following by those skilled in the art to which the present invention belongs Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
