The present invention relates to a device for removing carbon attached to a mini riser of a coke oven, and is particularly attached to a mini riser inner wall by equipping a U-tube with a disk-shaped scraper that can enter the mini riser. The present invention relates to a carbon removal device with a coke oven's mini lift pipe that can remove carbon quickly and easily.

In general, the coke oven has to discharge the generated gas and the coal to the outside without scattering coal because a large amount of gas and coal is generated inside the carbonization chamber in the process of charging the coal into the carbonization chamber.

This discharge process is connected to the mini riser 100a of the carbonization chamber and the mini riser 100b of the adjacent carbonization chamber as the U-tube 120 of the coke charging vehicle 110, as shown in FIG. In other words, the generated gas and coal in the carbonization chamber where coal is charged are introduced to the adjacent carbonization chamber and discharged to the outside.

However, in this process, a large amount of carbon is attached to the inside of the mini riser 100a and 100b, respectively, to block the internal flow paths of the mini riser 100a and 100b. The gas flow and the flow of powdered coal were greatly reduced, and a large amount of powdered coal and gas was generated when the coal was charged out of the coke oven due to the pressure increase in the carbonization chamber.

Attached carbon inside the mini riser (100a) (100b) is to be periodically cleaned, the conventional way to remove such carbon is as shown in Figure 5 the operator directly to the top of the coke oven 150 In this case, the tip was crushed to drop the attached carbon C inside the mini lift pipes 100a and 100b with a sharp spike 140 or the like.

This work process must supply high pressure air to the carbonization chamber in advance in order to prevent the flame and coal from leaking out from the carbonization chamber of the coke oven, and it takes a long time, and it is dangerous for the worker's safety accident by driving the coke charging car. Was very big.

The present invention is to solve the conventional problems as described above, to automatically and quickly remove the carbon attached to the inside of the mini riser, and to efficiently remove the carbon in the carbonization chamber to perform an efficient carbon removal device It is an object of the present invention to provide a carbon removal device with a mini riser of a coke oven.

In order to achieve the above object, the present invention, in the apparatus for removing carbon attached to the inner wall of the mini riser of the coke oven installation, a plurality of guide bars each formed with guide grooves on the upper portion of the vertical portion formed on both sides of the U-tube It is fixed upright, the guide groove is attached to the guide groove of the guide bar is disposed so as to move up and down, the screw member connected to the upper end to the rotating shaft of the drive motor is fixed to penetrate the vertical portion The lower end portion is extended to the inside of the vertical portion is screwed to the female screw member, the central portion of the upper surface of the disk-shaped scraper is connected to the lower end of the screw member to enable the up and down movement and rotation in the vertical portion, the outside of the drive motor The surface side is in contact with the upper and lower projections of the touch bar disposed in close proximity to the guide bar, respectively Is the phase of the motor, of the coke oven, it characterized in that the limit switch is fitted to limit the moving mini riser attached to a carbon removing device maryeonham.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

1 and 2 show a carbon removal device 1 according to the present invention.

The carbon removing device 1 includes a plurality of at least two upright guide bars 10 on the vertical portions 120a and 120b of the U-tube 120, and the guide bars 10 On the inner side of the guide grooves 10a continuous in the longitudinal direction are formed.

In addition, the guide rollers 10a are accommodated with guide rollers 12 so as to be able to slide, respectively, and the guide rollers 12 are rotatably mounted on the outer circumferential surface of the drive motor 15, so that the drive motor 15 is It has a structure that can be moved up and down along the guide bar 10 through the guide roller 12.

And, the drive motor 15 is fixed to the upper end of the screw member 17 to the rotating shaft (15a) facing downward, the screw member 17 forms a male screw portion 17a of the square cross-section, such a screw The member 17 is screwed to the female screw member 20 mounted to penetrate the vertical portions 120a and 120b, and the lower end portion thereof extends a predetermined length into the vertical portions 120a and 120b.

In addition, the lower end of the screw member 17 is mounted and fixed to the central portion of the disk-shaped scraper 22, a plurality of scratching projections (22a) is attached to the outer peripheral surface of the scraper (22).

In addition, the touch bars 25 are vertically mounted in parallel with any one of the guide bars 10 to the vertical parts 120a and 120b, and protrusions 27a and 27b are disposed on the upper and lower parts of the touch bar 25. ) Is formed, and the limit switch 30 attached to the outer circumferential surface of the driving motor 15 is in contact with the protrusions 27a and 27b of the touch bar 25 to adjust the upper and lower positions of the driving motor 15. Take control.

Reference numeral 32 is an energy supply line capable of supplying gas, fluid or electric power.

The present invention configured as described above, if you want to remove the attachment carbon (C) inside the mini riser (100a) (100b), the operator to the U-tube 120 is equipped with the present invention mini riser (100a) It is placed on the upper portion of the upper portion (100b), and operates the rotating shaft (15a) of the drive motor (15).

As a result, the screw member 17 connected to the rotating shaft 15a is rotated, which means that the screw member 17 is raised or lowered because the screw member 17 is screwed to the female screw member 20. Accordingly, the driving motor 15 and the disk-shaped scraper 22 coupled to the upper and lower ends of the screw member 17 are raised or lowered, and the guide roller 12 of the driving motor 15 is a guide. While coupled to the guide groove (10a) of the bar 10 to slide up and down along the guide bar 10, the disk-shaped scraper 22 is to be moved up and down simultaneously with the rotation.

That is, when the screw member 17 is rotated forward, the drive motor 15 is the guide roller 12 is lowered along the guide bar 10, the disk-shaped scraper 22 mounted on the lower end of the screw member 17 ) Will remove the attached carbon (C) in the mini riser (100a) (100b) while descending, rotating.

When the limit switch 30 mounted on the outer circumference of the driving motor 15 contacts the lower protrusion 27b of the touch bar 25, the limit switch 30 transmits an electrical signal to the driving motor ( The driving direction of the drive motor 15 is raised by rotating the screw member 17 in reverse direction by changing the rotation direction of the counterpart 15, and the disk-shaped scraper 22 also rotates upwardly, and the upper protrusion of the touch bar 25 is rotated. When the limit switch 30 contacts the 27a, the limit switch 30 transmits an electrical signal to block the energy source (gas, fluid or electric power) provided to the driving motor 15 to stop the rotation.

According to the present invention as described above, according to the forward and reverse rotation of the drive motor 15, the disk-shaped scraper 22 through the screw member 17 and the female screw member 20 is a mini riser (100a) (100b) By moving up and down while rotating the inside, the carbon attached to the inner wall (c) is scraped off.

At this time, the gas and the powdered coal scattered in the carbonization chamber are discharged to the adjacent carbonization chamber through the U-tube 120 during the removal of the adhered carbon (C), so that the scattering to the outside is prevented to pollute the surrounding environment.

Therefore, the practical effect is that the attached carbon of the mini riser inner wall can be removed quickly and safely.
