The present invention relates to a cooling device for high-temperature reduced iron.

The FINEX method is a wire making process for making molten metal, and the powdery iron spectrograph is evaporated from moisture in a drying device and reduced to a set reduction rate in a multi-stage flow reduction furnace at a set temperature.

And, in the manufacturing process of reduced iron (HCI: hot compacted iron), it is made into a lump form, transferred to a melting furnace, and melted with pure oxygen to make a pig iron.

The spectroscopic stone charged to the drying device takes several hours to be finally charged to the melting furnace, but if the operation situation inside the melting furnace suddenly deteriorates, the excess reduced iron (HCI) already made cannot be continuously processed in the process. It must be discharged to the outside.

However, when the reduced iron in a high-temperature state is exposed to the atmosphere as it is, it spontaneously ignites, lowering the reduction rate, reducing the product value, and damaging the downstream transport equipment such as a belt conveyor.

Therefore, there is a need for a device that quickly cools high-temperature reduced iron (HCI) in order to prevent reduction of the reduction rate and protect facilities.

The present invention aims to provide a cooling device for high-temperature reduced iron in which precision parts related to transport and cooling of reduced iron are not directly exposed to the cooling water in the process of bringing the high-temperature reduced iron into contact with cooling water to cool it to room temperature inside a cooling drum. do.

Therefore, since the transfer direction of the reduced iron and the transfer direction of the cooling water are opposite to each other in the space portion 110 of the cooling drum 100, the reduced iron can be easily cooled while mixing well with the cooling water.

Hereinafter, with reference to FIGS. 1 to 5, the operation of the cooling device for high-temperature reduced iron according to an embodiment of the present invention will be described.

First, through the charging chute 200 and the charging port 101 of the cooling drum 100, the reduced iron of a high temperature above a set temperature (for example, 500°C to 700°C) is transferred to the space 110 of the cooling drum 100. Flow in.

In addition, cooling water for cooling the reduced iron is supplied to the space 110 of the cooling drum 100 through the cooling water supply pipe 220 and the outlet 103 of the cooling drum 100.

At this time, the driving unit 400 drives the roller wheel 410 to rotate the cooling drum 100 at a rotation speed set in one direction (eg, clockwise).

As the cooling drum 100 is rotated, the transfer blade 300 is also rotated in one direction like the cooling drum 100, and the reduced iron introduced into the space 110 by the rotation of the transfer blade 300 is cooled. It is transferred from one end of the drum 100 to the other end (in the dotted line direction in FIG. 5 ).

In addition, the cooling water supplied to the space unit 110 through the outlet 103 by the cooling water supply pipe 220 is transferred from the other end of the cooling drum 100 to one end (dashed line direction in FIG. 5 ).

At this time, the cooling drum 100 has a center line (line O1-O1 in Fig. 1) along its longitudinal direction at an inclination angle θ set with respect to a horizontal reference line (line X1-X1 in Fig. 1). ) From the discharge port 103, the cooling water of the space unit 110 can naturally flow down from the discharge port 103 to the charging port 101.

Therefore, the cooling water is smoothly mixed with the reduced iron transferred from the space 110 to the outlet 103 while flowing naturally from the space 110 to the charging port 101, and thus the reduced iron is less than the set temperature by the cooling water. It will be able to be cooled down.

In addition, on the outer surface of the cooling drum 100, the anti-slip ring 450 protrudes in the outer direction of the cooling drum 100 and is disposed between the roller wheel 410 and the roller wheel 410, so that the cooling drum 100 ) Can be prevented from sliding in one direction by the rotation of the roller wheel 410.

In this way, the cooled reduced iron falls while colliding with the first guide plate part 231 and the second guide plate part 233 of the guide plate 230 installed at the discharge port 103 and enters the discharge chute 210, and flows into the discharge chute 210. The cooled reduced iron introduced into 210 is discharged to the belt conveyor 600 through the discharge chute 210.

In addition, when the reduced iron collides with the first guide plate part 231 and the second guide plate part 233, the cooling water mixed with the reduced iron passes through the first micro-holes 232 and the second micro-holes 234 to the space part. It is discharged, and the reduced iron collides with the first guide plate part 231 and the second guide plate part 233 and then falls downward and flows into the discharge chute 210.

Then, the reduced iron discharged to the discharge chute 210 is discharged to the belt conveyor 600 after sequentially passing through the steam scattering prevention unit 610, the steam dust collecting hood 620, and the steam scattering prevention cover 630.

The steam scattering prevention part 610 prevents the water vapor generated while vaporizing the cooling water permeating the reduced iron from scattering to the outside, and the steam dust collecting hood 620 sucks the water vapor generated from the steam scattering prevention part 610, The vapor scattering prevention cover 630 prevents the water vapor from scattering to the top of the belt conveyor 600.

Meanwhile, the cooling water flowing into the space 110 of the cooling drum 100 naturally flows down from the outlet 103 to the charging port 101 and mixes with the reduced iron moving in the opposite direction to the cooling water to cool the reduced iron. It is discharged to the storage tank 500 through the inlet 101.

At this time, the cooling water may generate sludge containing iron ore in powder form by mixing with reduced iron, etc., and is discharged into the storage tank 500 together with the sludge.

Since the sludge has a higher specific gravity than the cooling water, it sinks on the inner bottom surface of the storage tank 500, and this sludge is discharged to the outside of the storage tank 500 through the sludge discharge pipe 510 installed under the storage tank 500.

Among the cooling water discharged into the storage tank 500, sludge, etc., sink to the inner floor, and the remaining cooling water is in a relatively good quality, and the cooling water of such good quality is provided by the cooling water discharge pipe 520 installed on the top of the storage tank 500. It is discharged to the outside of the storage tank 500 through.

In addition, since the separating plate 530 is installed on the inner surface of the storage tank 500, the cooling water flowing into the storage tank 500 through the charging port 101 sinks to the inner bottom surface of the storage tank 500. It will not be mixed directly with the concentrated sludge.

Therefore, since the reduced iron and the cooling water are transferred in opposite directions in the inner space of the rotating cooling drum, the reduced iron is cooled, so that precision parts related to transportation and cooling of the reduced iron are not directly exposed to the cooling water, and thus can be isolated from the cooling water.

That is, the driving-related parts of the cooling drum are disposed outside the cooling drum, and the cooling water passes through the inside of the cooling drum, so that the driving-related parts can be isolated without being in direct contact with the cooling water.

Therefore, it is possible to prevent the problem of loss of bearing function due to accumulation of sludge inside the roller that occurs when using conveyors in the water tank.

Although the present disclosure has been described through preferred embodiments as described above, the present invention is not limited thereto, and various modifications and variations are possible without departing from the scope of the following claims. Those in the field will understand easily.
