Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a tar removal device for a coke oven,

The present invention relates to a tar removing device for a coke oven. More particularly, the present invention relates to a tar removing device of a coke oven, which comprises a moving part for sloping the dropped tar downward so as to more efficiently and completely remove tar falling or falling down during opening and closing of the coke oven, A scraping portion for reducing the fixing force of the transferred tar and a removing portion for removing tar finally formed on the moving portion and an apparatus for removing tar through a driving portion for transmitting power to drive the moving portion.

The present invention relates to an apparatus for removing solid matter of tar generated in a lower portion of a coke oven door during a coke oven extrusion operation by a transfer car in a coke oven operation.

In general, the coke oven facility for producing coke is configured such that the transfer car 2 is positioned and moved to one side of the coke oven 1, as shown in Fig.

The transfer car 2 serves as an extrusion guide so that the coal contained in the coke oven 1 is introduced into the coke oven 1 and the coke oven 1 carries out the coke oven for a predetermined period of time.

In such a coke oven facility, tar is generated in the inside of the carbonization chamber during carbonization of the coal, and the thus generated tar is adhered to or flows into the close contact portion of the coke oven door 3 formed on one side of the oven carbonization chamber, , A phenomenon occurs which interferes with desorption.

It is very important that the coke oven door 3 is normally opened and closed. Conventionally, as a means for solving the problem of sticking the cork oven door 3 by tar, a jamb cleaner 4 is mounted on the transfer car 2, As shown in Fig.

2A, a plurality of blades 5 are formed on the side of the coke oven door and are provided with a cylinder 7 and a scraper 8 as well as a cleaner body portion, After the coke is extruded by the coke oven door (2), the tar which flows down through the coke oven door to the outer lower side of the carbonization chamber is removed by the scrapers (8).

However, a problem with the conventional tar removing device constructed as described above is that tar scraping by the simple scraper 8 can not effectively remove the tar adhered to the bottom of the inclined surface.

Further, when tar flows out to the outside from the carbonization chamber, the tar is kept in a high-temperature state, so that it coagulates when it flows down to the floor, and thus the solidified state can not be easily removed.

Therefore, if the scrapers 8 are not completely removed, the remaining amount of tar is accumulated in the tar bar 9 formed on the outer inclined surface of the coke oven door.

If such solidified tar accumulates, there is a problem that the sealing strip of the oven door is damaged to cause a safety accident such as gas leakage, and it is impossible to remove / install the oven door severely.

In order to remove this, as shown in FIG. 2B, the operator removes the air with a breaker connected to the air.

However, in order for the operator to manually remove the tar, it takes a lot of time, which leads to an increase in work costs and an increase in the fatigue of the worker, resulting in a decrease in work efficiency.

In addition, this work area is a high temperature place, and a moving car and a tar removal work are performed in the same area. Therefore, there is a safety problem such as a safety of a worker being threatened.

As shown in the drawing, the present invention mainly includes a moving unit 100 for transferring dropped tar, a scratching unit 200 for hitting the tar, a removing unit 300 for removing tar, And a driving unit 400 for transmitting the driving signal.

3, the removing unit 300 is not shown but is formed under the scratching unit 200, which is shown in FIG. 4 to be described later.

The moving part 100 is a place where falling or flowing tar is seated when the coke oven door is opened or closed. In the past, tar dropped on a fixed type tar bar is seated, and the contact time with air becomes longer with time Finally, tar was fixed on the tar bar, which made it difficult to remove it.

In order to solve this problem, in order to overcome such a problem, the tar has fallen downward through the inclined tar bar, and it has been difficult to react with the air and to coagulate and remove the tar. The tar dropped by the present invention, There is a technical feature that the time of contact with the air is reduced by flowing down the belt 220 in a shorter time than in the prior art, thereby preventing the solidification.

Another constituent factor of the present invention is that since the scratch part 200 may still be fixed even if the tar dropped by the moving part 100 as the conveyor belt 220 moves fast, And the like.

That is, it is possible to prevent the tar from being fused to the conveyor belt 220 by applying a constant blow to the dropped tar, and the tar is primarily removed by the scraper 200.

The removing unit 300, which is another constituent of the present invention, is a device which is brought into close contact with the moving unit 100 to detach the tar whose fixing force is reduced by the scraping unit 200.

As described later, the removing part 300 is closely attached to the upper surface of the conveyor belt 220 so that the fixing force of the blade 310 is reduced by the scraping part 200 After the material of the tar itself is softened, the conveyor belt 220 is rotated and the tar is moved and removed by the blade 310. [

The driving unit 400 performs a function of transmitting the power so that the conveyor belt 220 provided in the moving unit 100 can be rotated so that the above-described functions can be realized.

The moving part 100, which is realized so as to shorten the contact time of the dropped tar with air, is constituted by a conveyor belt 220 which is inclined in the downward direction of the coke oven door.

The conveyor belt 220 is installed at the position of the tar bar on which the tar is placed, and thus prevents the tar from being fixed to the tar bar in the form of a movable tar bar.

Of course, it is obvious that the material of the conveyor belt 220 should be formed of a material that can withstand high-temperature tar.

And the tar dropped by the conveyor belt 220 is moved to the scraper 200.

As shown in FIG. 3, the scratch 200 according to the present invention is formed on the lower portion of the lower portion of the conveyor belt 220 that moves the dropped tar, so as to apply a constant blow to the tar.

A plurality of protruding crushing protrusions 210 are formed on the outer circumferential surface of the scratching part 200 so as to be spaced apart from each other by a predetermined distance so as to apply a uniform impact to the tar. .

The first and second frames 411 and 412 are formed on both sides of the conveyor belt 220 to support the conveyor belt 220 and other peripheral devices. The engaging rod 212 protruding in the longitudinal direction of the scraping portion 200 is inserted into the engaging hole 211 so that the scraping portion 200 can rotate.

FIG. 4 is a view showing the tar removing device of the coke oven according to the present invention, viewed from the direction of the bottom surface, with the removal part 300 mounted thereon.

As shown in the drawing, the removing unit 300 is disposed in the width direction of the conveyor belt 220 so as to remove the tar located on the upper surface of the conveyor belt 220, And a blade 310 which is in close contact with the conveyor belt 220.

The blades 310 are mounted on the inner surfaces of the first and second frames 411 and 412 provided on both sides of the conveyor belt 220 and are fixed by the scratches 200 to reduce the fixing force, So that the soft material of the tar is separated from the conveyor belt 220.

At this time, it is preferable that the material of the blade 310 is made of a material which does not damage the bar conveyor belt 220 which is in close contact with the conveyor belt 220 and removes the tar on the upper surface thereof.

3 and 4, the drive unit 400 for providing power to rotate the conveyor belt 220 includes a drive chain 410, a motor 420, a speed reducer 430, and first and second sprockets 415, 416, and first and second fixed axes 413, 414.

The first and second frames 411 and 412 are mounted on both sides of the conveyor belt 220. The first and second frames 411 and 412 are rotatably coupled to the first and second frames 411 and 412, And a conveyor belt 220 is cemented to the teeth formed on the first and second sprockets 415 and 416.

The first and second fixing shafts 413 and 414 are respectively formed in the lateral direction of the first and second sprockets 415 and 416. As shown in the figure, And a speed reducer 430 for controlling the speed of the motor 420 is connected to one side of the motor 420. [

The first sensor 510 may be formed on one side of the coke oven door, and the second sensor 520 Is attached to the extruder 10 and a control unit 500 for determining whether the moving unit 100 is driven is formed around the apparatus.

The glow coke which has been produced in the coke oven carbonization chamber is discharged from the inside of the carbonization chamber to the tanks. In order to properly discharge the gaseous coke, the gaseous coke is extruded by the ram provided in the extruder 10.

Upon completion of the coke discharging operation by the ram, the extruder 10 and the transfer car close the door of the coke oven and move to the next working position.

Another feature of the present invention is that when the above operation is performed, when the extruder 10 is moved to the coke oven door, the moving part 100 is operated to remove the falling tar, and the extruder 10 is moved to the other door And the operation of the moving unit 100 is stopped when a predetermined time elapses after the moving.

As shown in the drawing, a first sensor 510 for transmitting a position signal is formed on one side of the coke oven door, and the extruder 10 moving in front of the coke oven door is spaced apart from the first sensor 510 by a specific distance And a second sensor 520 for sensing a signal sent from the first sensor 510 is attached.

Positioning at a specific distance refers to the position where the preparatory work for setting the extruder 10 to move forward in the coke oven door and extruding the glow coke is set and the movement to the front of the door for the operation of the extruder 10 Upon completion, the second sensor 520 attached to the extruder 10 senses a signal from the first sensor 510 located at one side of the coke oven door.

When the second sensor 520 detects a signal from the first sensor 510, the moving unit 100, that is, the motor 420 for rotating the conveyor belt 220 is operated to remove tar falling The work is going on.

When the operation of the extruder 10 is completed and the falling tar is also removed by the operation of the drive and removal unit 300 of the moving part 100, the extruder 10 moves to work with the other door, The controller 520 can not detect the signal generated from the first sensor 510 and the controller 500 recognizes the signal and then rotates the moving part 100, that is, the conveyor belt 220, The operation of the motor 420 is stopped.

The tar falling through the controller 500, the first and second sensors 510 and 520 is automatically removed, and when the extruder 10 moves to another door, Continuous work can proceed as it is removed.

As described above, the tar is moved downward in an inclined direction so that the falling tar is shortened during the opening and closing operations of the coke oven door, the tar is firstly damped, and the continuous tar To soften the material of the tar, and finally to remove the tar.

The operation process of the present invention having the above-described configuration will be briefly described.

The conveyor belt 220 inclined in the downward direction of the coke oven door starts to rotate so that the tar dropped in the direction of the scraping part 200 can be moved quickly when there is falling tar at the opening and closing of the coke oven door.

And a speed reducer 430 for controlling the rotation speed of the motor 420. The speed reducer 430 controls the rotation speed of the motor 420 according to the speed set by the operator, Rotates and the tar placed on the upper portion moves to the scrape portion 200. [

The scratching part 200 has a circular shape in a circular cross section and has a plurality of protruding shredding protrusions 210 for softening the material of the tar itself by applying a constant blow to the tar to the outer circumferential surface of the scratching part 200, Is formed in the longitudinal direction of the cylinder.

The protruding crushing protrusions 210 reduce the fixing force of the tar while softening the material thereof. The continuous rotation of the conveyor belt 220 causes the tar to reach the removal unit 300.

The other tar in the removal unit 300 is scraped off by the blade 310 closely attached to the conveyor belt 220, and the tar removal operation is completed.

In order to perform the above process automatically, a first sensor 510 is installed on one side of the coke oven door and a signal of the first sensor 510 is also detected on the extruder 10 moving in front of the coke oven door A second sensor 520 is attached.
