Description

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

The present invention relates to a device for cleaning a reversing cock of a coke oven, and more particularly, to a reversing coke cleansing device for a coke oven for easily removing foreign matter adhering to a coke ball inside a reversing cock.

Generally, Cokes, a subsidiary material to be used when producing molten iron in a blast furnace, is a type of coal charcoal used as a heat source and a reducing agent in a blast furnace and used as a means for securing air permeability, and is produced in a coke oven.

FIG. 1 is a schematic view showing a general coke oven operation process. As shown in FIG. 1, a coke oven 1 is a coal carburizing apparatus used for producing a coke as a sub- A carbonization chamber (20) for heating and charging the raw material is formed.

In the coke production process, coal having a certain degree of cohesion is charged into the carbonization chamber 20 of the coke oven 1 through the four entry openings using a charging car 30 from the hearth of the coke oven 1 The coke oven 1 is indirectly heated at a temperature of 1,300 degrees Celsius in a sealed state, and is then subjected to carbonization for about 18 hours. The finished glow coke is pushed out of the coke oven 1 by the pusher car 40.

At this time, the red coke C led to the transfer car 50 is loaded on a bucket of a quenching car at the opposite side of the coke oven 1, and is subjected to CDQ (Coke Dry Quenching) . Then, the coke is discharged, and the carbonization chamber 20 recovers coal into the empty coke oven 1.

A combustion chamber is provided on both sides of the carbonization chamber. In the combustion chamber, a mixed gas composed of a coke oven gas and a blast furnace gas is combusted together with oxygen to be introduced, And is discharged to the outside through the exhaust side at a predetermined time interval.

While the exhaust gas is being exhausted, the supply of the mixed gas is interrupted and the mixed gas is supplied again after about 20 to 30 minutes. The reversing process of exchanging the mixed gas for interrupting the supply of the mixed gas and resuming the supply of the mixed gas is called a reversing process. The reversing device for performing the reversing process includes a reversing coke 60 and a cylinder for operating the reversing cock 60.

Conventional reversing corks are specifically known in, for example, "apparatus for removing leakage gas of a coke oven reversing apparatus (Patent No. 10-0805046) ".

2 is a schematic view for explaining a general reversing cock;

2, generally, the reversing cork 60 is provided with a cork ball 61 for opening and closing a passage therein. When the cork ball 61 rotates, the reversing cork 60 And controls the mixed gas supply as it is opened and closed.

At this time, the reversing cock 60 is adhered while being accumulated on the cock ball 61 accommodated therein, such as tar, naphthalene, iron oxide, etc. generated during the supply of the mixed gas, so that the channel formed in the cock ball 61 is blocked A phenomenon occurs. Therefore, the supply efficiency of the mixed gas is lowered, and the internal temperature of the carbonization chamber 20 is lowered.

When the foreign object is fixed and the cork ball 61 is clogged, the cork ball 61 is separated from the reversing cork 60 so that the inside of the casing 62 of the reversing cork 60, Perform ball cleaning (61).

However, the cork ball 61 is difficult to handle as a heavy weight, and has a problem in that it takes a lot of manpower and time to separate from the reversing cock 60.

Further, the reversing cork 60 is installed in a relatively narrow space above about 2M from the ground, causing a safety accident such as a fall of a worker during a scouring operation, and the working efficiency is lowered.

Further, since the efficiency of the purging operation is lowered and the time required for the purging operation is delayed, the supply of the mixed gas is interrupted for a long time and the quality of the coke is deteriorated.

The rotary motor 723 is installed in one of the pair of the mounting sockets 722. The rotary motor 723 is coupled to the rotary shaft of the cork ball 61 to perform the cleaning operation while rotating the cork ball 61, It is possible to improve the working efficiency and shorten the working time.

The operation of the reversing coke scavenging apparatus for a coke oven according to an embodiment of the present invention will be described with reference to the drawings.

3, the body 100 is moved to the front of the mixed gas pipe 70, and the fixed cylinder 140 is operated to fix the body 100 on the ground so that the body 100 is not moved.

When the body 100 is fixed to the ground, the first truck 300 is advanced along the first running rail 200 in the direction of the reversing cock 60 installed on the mixed gas pipe 70 The second carriage 500 is positioned in front of the reversing cork 60 to be cleaned along the second driving rail 400.

When the movement of the second bogie 500 is completed, the supporting cylinder 510 is extended downward so that the end of the supporting cylinder 510 is in contact with the mixed gas pipe 70, The withdrawing cylinder 610 is operated so that the cock ball receiver 620 is lifted up in the pulling out position of the cockball 61 and the cockball 61 is lifted from the reversing cock 60 And is seated on the cock ball receiver 620.

When the withdrawal of the cock ball 61 is completed, the support cylinder 510 is operated so that the second bogie 500 can move, and the second bogie 500 drives the second travel rail 400 And moves to the upper portion of the first carriage 300. [0050]

When the second bogie 500 is positioned on the first bogie 300, the first bogie 300 is moved along the first bogie rail 200 to position the bogie to be purged, The cork ball 61 mounted on the cork ball receiver 620 is moved so that the rotation axis of the cork ball 61 is coupled to the crawler socket 722 Rest.

When the cock ball 61 is seated in the mounting socket 722, the rotary motor 723 is operated to perform the cleaning work while rotating the cock ball 61.

After the cleaning operation of the cork ball 61 is completed, the first crawler 300 and the second crawler 500 are moved in the direction of the reversing cork 60, and then the cork ball 61, Is inserted into the reversing coke (60) and the purging operation is completed.
