Description

Flow resistance cleaning device {Apparatus for cleaning of current register}

The present invention relates to a flow rate resistor required during the drilling operation, which is a steelmaking process for refining molten iron with molten steel, and in particular, it is possible to simultaneously install and detach the body of the flow resistance resistor in a short time so as to clean the flow resistance resistor automatically. The present invention relates to a flow rate resistance cleaning device.

In general, flow rate resistors can be reused to prevent equipment wear due to dust collection during the process of injecting 99.9% of pure oxygen through oxygen lance after charging molten iron and scrap metal in the converter furnace. It is a device to induce a safe flow into reprocessing equipment.

1 is an overall state diagram in which a conventional flow rate resistor is mounted.

Where 11 is a converter, 12 is a settling tank for recycling, 13 is a drain line, 14 is a seal tank, 15 is a washing pipe, and 40 is a flow rate resistor to be.

Therefore, the flow rate resistor 40 is used to improve the cleanliness of the exhaust gas generated in the process of refining the molten iron to molten steel in the converter 11 and to prevent air pollution.

In the course of the exhaust gas passing through the water film formed by supplying the dust collector to the primary dust collector, the wet dust collector is introduced into the 1DC seal tank 14 through the primary elbow through the throat damapa.

The flow rate of the dust collector discharged through the 1DC seal tank 14 is lowered and flows to the settling tank 12 which is a reprocessing facility. As a part to prevent abrasion, the flow rate resistor 40 is installed.

However, if excessive dust is attached to the plate attached to the inside of the flow resistance resistor 40 installed to prevent wear of the 1DC return pipe, the flow rate collector 40 does not extinguish the dust collection flow rate flowing from the primary dust collector 40. Overflow will occur. Accordingly, there is a problem that not only pollute the surrounding equipment, but also the amount of recovery is reduced during the dust collection re-processing to increase the cost burden, causing a reduction in dust collection efficiency due to unbalance of the quantity.

Recently, the amount of dust adhered to the plate attached to the flow resistance resistor 40 is increased due to the increase in the use frequency of the converter 11. The flow resistance resistor 40 itself is conventionally manufactured in one piece, and the inner plate is It takes a long time to remove the attached dust due to the attached relationship, so it is operated in the form of incision by partial cutting only during long periods of rest and after re-welding the incision.

As described above, in the past, as the number of converters is gradually increased, the amount of dust attached to the plate attached to the flow resistance resistor 40 increases, but the flow resistance resistor 40 itself is integrated. In addition, the plate was mounted inside, and the removal of adherent dust was required for a long time, so it was indispensable only by long-term rest of the converter to remove dust attached to the inside, and then re-welded the cut portions.

In addition, the number of use of converters has increased recently, and the change in the operation pattern has led to an increase in the number of operating days of repairs of two out of three existing ones. (2 ~ 3 days) There are some difficulties that are difficult to secure.

In addition, in recent years, due to the improvement of environmental protection awareness level, excessive dust is attached to the plate part inside the flow resistance resistor, and thus the unbalanced dust collection is linked to the reduction of dust collection efficiency, which is a serious problem. .

In addition, when the plate is installed inside the flow resistance resistor, it is difficult to sufficiently perform the role as the flow resistance resistor when performing the removal dust removal work by cutting only a part. Conventionally, the vicious cycle of cutting and then collecting several parts is repeatedly repeated. In addition, the dust removal work time and the workforce are excessively consumed, resulting in a cost increase and a decrease in productivity in terms of manufacturing cost and productivity of molten steel.

Accordingly, the present invention has been proposed to solve the above-mentioned conventional problems, and an object of the present invention is to simultaneously install and detach the body of the flow resistance resistor in a short time so that the flow resistance can be automatically cleaned. To provide a flow rate resistance cleaning device that can be.

In addition, another object of the present invention is to provide a flow rate resistance cleaning device that can shorten the time required by the installation and detachment of the flow rate resistance in a short time.

In addition, another object of the present invention is to provide a flow rate resistor cleaning device that can be installed, detached and cleaning the flow rate resistor automatically to suppress the occurrence of disasters that may occur when handling heavy objects by manpower.

Furthermore, another object of the present invention is to improve productivity by setting and securing spare parts manufactured to be replaceable for each part of the flow resistance resistor, thereby providing advantages in terms of cost, productivity, and environment. To provide a flow rate resistor cleaning device.

So, as shown in Figures 2 to 4, the operation from the removal until the cleaning is described as follows.

The clamps 21 and 22 are positioned on the center line of the flow rate resistor 40 and then the height is adjusted to the flow rate resistor 40 which needs to remove dust by using the lifting cylinder 34.

Then, the fixed clamp 21 is brought into close contact with the flow rate resistor 40 requiring cleaning, and the clamping motor 22 is driven to move the variable clamp 22 to clamp the flow rate resistor 40 requiring cleaning.

When the turn table driving motor 31 is operated to rotate the turn table operating rod 27 through the reducer gears 29 and 30, the clamped flow resistance resistor 40 is detached.
