Description

Repair material input device {Apparatus for Supplying Mending Materials}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refilling device for repairing an inner wall in an industrial furnace of a steel mill factory or other industrial field urine industry such as a coke oven, a heating furnace or a heat storage chamber, and more particularly, coke with high heat. Maintenance of the equipment is performed stably by adjusting the feed rate and input amount of the repairing material and uniform and stable spraying during the repair work such as carbonization of the oven, built-in riser of the riser, storage of the heat storage chamber, or the bottom of the carbonization chamber. The present invention relates to a repair material input device for suppressing harmful gas emissions to the atmosphere through the facility.

In general, cokes transmit the radiant heat generated by heating from the lower part to the coke oven carbonization chambers formed at both sides, and cut off the air after high temperature dryness to return the gas to a heat source (about 1200 ° C to 1300 ° C) for about 17 to 18 hours. It uses the principle of the under jet system, which allows combustion to produce high strength coke products.

At this time, the yeonwa (silica) that is built inside the coke oven carbonization chamber is caused to be repeated shrinkage and expansion due to high temperature, and the mortar built up between the yeonwa is removed, thus the non-combustion generated during the charging process of coal Raw gas is introduced into the combustion chamber through the gap between the lead and discharged to the outside as it is, which causes air pollution and shortens the life of the carbonization chamber and the combustion chamber due to the unburned gas.

Therefore, in an industrial furnace or other industrial field urinary industry of a steel mill factory such as a coke oven, a heating furnace or a heat storage chamber, for example, a repair material is sprayed into the carbonization chamber to continuously repair the gap between the smoke and the smoke.

For example, although not shown in a separate drawing, a conventional water refilling device is provided with a water reserving material storage tank on a movable trolley equipped with wheels, and connects a compressed air supply pipe to the tank to discharge the water retaining material in the tank forward. The long-term water supply material supply hose connected to the lower part of the water supply material storage tank is connected to the water supply nozzle which enters the inside of the furnace and sprays the water supply material. Such a spray nozzle is normally used for the life of the furnace equipment. It is a structure that protects from heat by installing an entrance cover formed to correspond to the entrance.

However, such a conventionally known repairing material injector does not take into consideration the internal pressure or the repair position of a furnace equipment, for example, a coke oven carbonization chamber, and simply uses compressed air for a predetermined time (approximately 4 to 10 minutes) to supply the repairing material. As a result of the spraying, the repair material was not evenly inserted into the furnace lead and the gap, and the furnace and clearance repair efficiency through the repair material was also low.

In addition, as the repair material sprayed into the coke oven carbonization chamber is inserted into the lower part of the carbonization chamber rather than being inserted into the gap between the lead and the other side of the carbonization chamber, unnecessary waste of the repair material is generated, which causes another problem of increasing the cost burden. .

In addition, the repair material accumulated in the lower part of the carbonization chamber entails cumbersome additional work that needs to be removed again.

In particular, the conventional refilling device has not been able to freely adjust the input amount and the feeding speed of the refilling material, thus making it difficult to efficiently spray the refilling material.

Therefore, in the repairing material injector 1 of the present invention, as shown in Figures 3 and 4, the repairing material in the storage tank 30 is supplied to the ejector 54 when the rotary valve 52 is operated by a motor associated with the rotary valve 52. At this time, unlike the conventional high-pressure gas, for example, inert gas or high-pressure gas of air is supplied from the rear and side of the ejector through the supply pipe, respectively.

Therefore, as shown in FIG. 6, since the high pressure gas is supplied in the state where the high pressure gas supply pipe is connected to the rear and the side of the ejector, respectively, in the apparatus of the present invention in which one gas supply is made, the amount of repair of the repair material is substantially controlled. B It is easy to control the ejection speed, in particular, the injection of the repair material into the facility through the injection means 70 enables a very uniform and stable injection injection.

At this time, as shown in Figure 2 and 3, the rotary valve 52 is driven by the power of the drive motor 60 installed in the device frame 10, such a drive motor 90 is provided in the tank. It is configured to transfer the power to the stirring means 90 together.

At this time, the gear box 94 is schematically shown in the drawings, but a pair of bevel gears are engaged with each other in a direction perpendicular to each other, and each bevel gear has a connecting shaft 95 and a stirring means rotating shaft 92. ) Is connected so that power is transmitted to the rotating shaft 95 and the inner gear and the rotating shaft 92 of the gearbox by the motor power to enable stirring.

Therefore, when the drive motor 60 is operated, while the rotary valve 92 and the rotary shaft 92 of the stirring means 90 is rotated to operate, the stirring blade 94 prevents the repair material inside the tank from being attached to the tank wall. Dropping so as to smoothly eject through the rotary valve (52).

At this time, the gear box 92 is connected to the fixed bar 93 connected to the tank inner wall, as shown in Figure 3, the rotating shaft 92 may also be supported to rotate vertically in the center of the tank by a bearing or the like, The stirring blade 94 and the rotating shaft 92 are connected by a connecting rod 96.

Accordingly, in the water refilling device 1 of the present invention, the stirring means 90 as well as the rotary valve 52 which affects the tank discharge of the water retaining material are interlocked together.

Of course, in the present embodiment, it has been described that the motor driving force is transmitted to the sprocket and chain, of course, it is also possible to transfer the power using other known belt (Belt) and pulley (Pulley).

In addition, the rotary valve 52 through which the rotational force is transmitted by the operation of the driving motor 60 may be controlled by the rotation of a rotating fan (not shown) therein as a motor control, and the water is discharged through the rotary valve. Emissions and discharge rates of M) can be controlled.

On the other hand, as shown in Figures 4, 5a, b and 6, in the device of the present invention, that is, the ejector 54 is the rotary valve 52 and the rear high-pressure gas supply pipe 56a is connected respectively, The first pipe 64 is connected to the branch connecting pipe 62 and the second pipe 66 is assembled to the first pipe 64, the side of the high-pressure gas supply pipe 56b is connected.

That is, as shown in Figure 6, the branch pipe 62 is the first branch pipe (62a) and the second branch pipe (62b) and the first and second connected to the rear high-pressure gas supply pipe (56a) connected to the rotary valve.

Therefore, as shown in Figs. 5 and 6, since the high-pressure gas is supplied to the ejector 54 in the repairing material injector 1 of the present invention, the ejector 54 is more smoothly ejected, that is, the repairing material supply hose 58 And the ejection to the repair material injection means 70 is made.

On the other hand, the supply hose 58 is preferably formed of a material having a heat resistance for preventing damage and deformation caused by heat generated in the facility, for example, carbonization chamber and the surrounding equipment, or use a hose heat-resistant outer peripheral treatment Do.

At this time, as shown in Figure 5b, the high-pressure gas blowing passage 68 is formed between the first and the second tube of the ejector 54 of the present invention.

Therefore, the high pressure gas supplied through the rear high pressure gas supply pipe 56a connected to the branch pipe in FIG. 6 smoothly flows the water retention material M introduced into the branch pipe through the rotary valve 52 to the ejector 54. Then, the high pressure gas supplied to the side high pressure gas supply pipe 56b supplied to the side of the second pipe of the ejector ejects the high pressure gas G through the passage 68 between the first and second pipes inside the ejector. The repair material in the ejector will be ejected very smoothly.

As a result, in the water refilling device 1 of the present invention, the high-pressure gas G supplied to the rear and side high-pressure gas supply pipes 56a and 56b connected to the branch pipe and the ejector second pipe, for example, high pressure You can easily adjust the ejection amount or speed of the repairing material according to the air supply amount or pressure.

At this time, as shown in Figure 5b and Figure 6, in the water refilling device of the present invention, the high-pressure gas blowing passage 68 between the first and second pipes is spaced in the high-pressure gas blowing direction to increase the high-pressure gas blowing speed. (D) is formed to decrease gradually.

Therefore, the velocity of the high pressure gas which is ejected into the second pipe through the high pressure gas blowing passage is rapidly increased at the end of the passage.

This is because the gap D is reduced by making the high pressure gas jet passage part of the second pipe convex.

In addition, it is known that such passage interval adjustment causes a Venturi effect to increase the high-pressure gas passage ejection rate.

Next, the ejector outlet 54a of the ejector 54, that is, the ejector ejection outlet 54a connected to the flange F to the second tube 66, is connected to the repair material supply hose 58, and the repair material M is shown in FIGS. As shown in FIG. 7, the internal gas is uniformly and stably ejected between the insides of the carbonization chamber through the water outlets 70a and 70b of the injection means 70 injected through the carbonization chamber charging port of the coke oven. Shut off external spills.

At this time, the injection means 70 is provided with a cover plate 72 to block the carbonization chamber charging port to block the external leakage due to the external leakage of the internal gas or scattering of the repair material, as shown in Figs.

In addition, although not shown in the drawings, as shown in FIGS. 3 and 7, the X-shaped shape to more widely diffuse the injection of the water retaining material (M) to the ejection port of the water holding material injection means 70 of the present invention It is preferable that a diffusion plate of is provided.

In addition, although the cover plate 72 of the injection means is not indicated by a separate code, it is also preferable to install a pressure gauge for measuring the internal pressure of the carbonization chamber, in which case it is easy to know the internal pressure of the carbonization chamber to determine whether to insert the repair material. Will make it possible.

For example, when the internal pressure of the carbonization chamber is low, the internal cracks or gaps of the carbonization chamber may be generated as much. On the contrary, when the internal pressure is above a certain level, it may be determined that there are no cracks or gaps.
