Description

Iron oxide recovery equipment {A Oxide Iron Collection Equipment}

The present invention relates to an apparatus for producing iron oxide so that the iron oxide generated during the rolling operation in the hot rolling mill and mini mill plant can be automatically collected and recycled in the water treatment process, in particular, a large amount is mixed in the cooling water during the rolling operation in the water treatment process Iron oxide recovery device to automatically collect iron oxide flowing into the iron oxide pit and separate iron oxide and foreign matter so that iron oxide can be granulated to a certain size so that it can be recycled without reprocessing, improving work efficiency, reducing cost and improving productivity It is about.

In general, during hot rolling operations in hot rolling mills and mini mills, a large amount of coolant is sprayed on a hot strip to remove iron oxide, and a work roll and back-up roll of the FM line are carried out. Cooling water is also used for front and rear cooling and table roller and strip cooling. A large amount of iron oxide contained in the cooling water used in the above operation is introduced into the iron oxide pit of the water treatment process line together with the cooling water.

In the iron oxide pit where the coolant and the large amount of iron oxide are introduced, the iron oxide precipitates to the bottom, and the coolant introduced into the iron oxide pit is sent to a filter tank for recycling, reprocessed and sent to the cooling water tank and continuously supplied to the rolling line.

As a method of collecting a large amount of iron oxide introduced into the iron oxide pit in the working process, as shown in FIG. 1, there is a traveling crane on the top of the square iron oxide pit 2 and the traveling crane has a basket 3 for collecting the iron oxide. It is installed so that the crane operator drops the basket 3 into the water in the iron oxide pit to recover the iron oxide 1, and the iron oxide pit is square and the pit bottom is flat so that the iron oxide is extensively stacked and the iron oxide cannot be visually checked. Partial collection is made by judging and the iron oxide contained in the basket is loaded again in the temporary storage unit 4 and the loaded iron oxide is transported to the vehicle using the basket after a long time of drying.

This work process is a simple repetitive operation of the crane operator, which may cause the accident of equipment accidents due to misoperation. When the iron oxide contained in the basket is moved to the crane, it causes corrosion and environmental pollution of the surrounding equipment. Since manpower is required and iron oxides transported to other places can be used only after reprocessing, there are problems such as productivity loss, cost increase, and work efficiency.

In addition, the conventional work process, as shown in the Republic of Korea Patent Publication No. 2003-46246, when the iron oxide picket is assembled to the basket belt when the iron oxide is collected in the iron oxide pit causing the belt movement during driving and foreign matter (wood, plastic, Paper and non-ferrous metals) may be pinched between the iron oxide bucket and the body, causing damage to the bucket and equipment accidents, and damage to the bucket roller when the iron oxide flows between the bucket and the belt. When the iron oxide collector is removed on the iron oxide pit of the iron oxide, the iron oxide accumulated in the body part may cause overloading while the iron oxide is accumulated on the body part. Has been pointed out that it is difficult to transport and handle All.

The present invention has been made in order to solve the above problems, the iron oxide pit to a circular rather than a square, to allow the recovery of iron oxide on the side oblique portion of the circular iron oxide pit, the scale introduced into the iron oxide pit concentrated in the center It has an air spraying device so that it can be used, and a foreign matter separating device that separates iron oxide and foreign matter. It produces iron oxide which is easy to handle and transport by granulating iron oxide to a certain size and does not need to be reprocessed during use. The main object of the present invention is to provide an iron oxide recovery apparatus that makes it easier and simpler to collect and reuse iron oxide.

It is connected to the coupling 112 and driven in a clockwise and counterclockwise direction, the roll 110 has a uniform semi-circular groove 116 is dug so that each semi-circular groove 116 can form a circle when driven. Iron oxide produced by the roll 110 is configured to be collected in the storage unit 200 to fall to the bottom.

Hereinafter will be described the operation of the present invention.

As shown in FIG. 2, the lower portion of the circular iron oxide pit 10 forms a slope 12 so that the iron oxide 1 can be continuously collected at one point, so that the iron oxide 1 coming from the iron oxide inlet is collected at the center. As shown in FIG. 3, when the cylinder 60 of the air injection device for preventing iron oxide pooling is operated so that the iron oxide 1 coming from the iron oxide inlet 11 may be smoothly gathered to the center, the cylinder 60 is connected to the rod. The fixed circular air frame 65 is operated at the bottom to be positioned at the bottom of the inclined pit, and the air is supplied to the circular air frame 65 through the air pipe 61 and the air hose 63 so that the air injector ( The air is sprayed through 66 to operate the iron oxide 1 to be rapidly collected at the center.
