Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a coke oven door frame processing apparatus,

The present invention relates to a coke oven door frame processing apparatus, and more particularly, to a coke oven door frame processing apparatus capable of processing and repairing a modified door frame of a coke oven in the field.

A coke oven is a device that carries out coking oven by charging carbon black into a carbonizing chamber and carries out bulking. The carbonized coke is withdrawn from the coke oven and used as fuel for the furnace.

Generally, a coke oven is formed with a carbonaceous chamber for carbonizing coal, and a door frame for installing a coke oven door is installed at a carbonation chamber entrance.

As shown in FIGS. 1, 2A and 2B, a hook bar 14 for supporting the coke oven door 12 is installed on the front surface of the door frame 10.

The door frame 10 functions to detach the coke oven door 12 when the nebulization is completed in the carbonization chamber in the coke oven and the new coke is charged again when extruding the coke oven door 12, And is kept in close contact with the coke oven door 12 to maintain the airtightness of the carbonization chamber, thereby functioning to prevent the gas generated in the coke oven chamber from leaking out.

However, if deformation of the door frame 10 due to high temperature and temperature changes occurs, the adhesion with the coke oven door 12 is lowered and the gas generated during the coal combustion is leaked. As a result, Various problems arise.

Therefore, when deformation occurs in the door frame 10, the door frame 10 must be replaced or repaired. However, when the door frame 10 is replaced with a new one, there is a problem that the cost increases.

In the case of repair, there are a number of prior arts for the door frame 10 to be detached from the coke oven and removed and moved to a separate work site.

Korean Patent Laid-Open Publication No. 2003-0045288 (Jun. 11, 2003) discloses a "coke oven front entrance lifting device. &Quot;

This is an improvement of the structure of the loading car door lifting device which cargoes and removes the cargo seal door in order to load coal into the carburizing chamber, and it enables efficient facility management by securing the repair space and reducing the installation area of the equipment.

However, the process of moving the door frame 10 as well as the coke oven door 12 is very cumbersome and dangerous, and there are disadvantages that a lot of personnel and equipment must be input from disassembly to processing, In the case where a problem arises in the door frame 10, there is an urgent need for an apparatus for repairing and processing the same in the field.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as adhering to the prior art already known to those skilled in the art.
