Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a furnace wall repairing device having a temporary furnace lid temporarily attached to a kiln opening in hot repairing a damaged furnace wall surface of a coke oven.

[0002]

2. Description of the Related Art Coal charged into a carbonization chamber of a chamber furnace type coke oven is carbonized by indirect heating from both side combustion chambers through a furnace wall into coke, and is extruded into a coke bucket or a coke guide through a coke guide. It is extruded into a fire engine and cooled in a coke dry fire extinguisher facility or a wet fire tower.

Therefore, in the chamber furnace type coke oven, each part is damaged due to the action of mechanical external force, thermal stress, charged coal moisture, etc. during many years. In particular, since the action based on the above-described factors is concentrated on the carbonization chamber wall, damages such as breakage of joints, generation of cracks, and missing bricks are likely to occur. When such damage occurs, incomplete combustion occurs due to the inflow of coke oven gas from the carbonization chamber to the combustion chamber, which causes pollution problems due to black smoke from the chimney and a decrease in productivity due to a local decrease in combustion chamber temperature. However, this causes problems such as clogging due to an increase in the amount of pyrolytic carbon attached to the furnace wall. For this reason, mortar is sprayed on the damaged portion with low durability, and when the damage is large, bricks that require high repair costs have been replaced.

The life of a conventional coke oven furnace is 20 to 2 years.
It has been said that it will last for about 5 years, but recently it is expected that it will last 30 to 35 years by adopting a method of repairing damaged parts of the furnace wall by spraying and improving the accuracy of diagnosis of damaged parts of the furnace wall. Is coming.

Repair of the damaged portion of the coke oven wall is performed by a method adapted to the degree of each damage, but in most cases, it is done from the machine side of the coke oven or the coke side kiln. Spraying or spraying refractories to the damaged portion of the furnace wall is usually performed hot by utilizing the interruption time of the coke kiln, and thus protects the worker from radiant heat of the furnace wall and Measures to prevent cold air from entering are becoming important.

As a countermeasure against the above-mentioned hot repair, a spraying machine (Japanese Utility Model Publication No. 55-164340) in which a guide roller provided in a spray nozzle that can move vertically moves vertically along a guide rail and a heat insulating plate, is used. The lower end of the upper cover that substantially shields the kiln opening above the arm from the outside air and the upper end of the lower cover that substantially shields the kiln opening below the blowing arm from the outside each have a set gap for forming the monitoring opening in the carbonization chamber. , A protective cover device in which an upper and lower cover is connected to an elevating device so as to move up and down in conjunction with the raising and lowering of an arm (Japanese Utility Model Publication No. 58-42421), a frame main body corresponding to a kiln has a plurality of longitudinal directions. A knife edge is provided along the outer peripheral surface of the frame main body of the temporary furnace lid, which is a divided size and has a plurality of doors with heat insulating material inside in parallel and attached in a freely openable and closable manner. The knife edge can be extruded by a plurality of pressing spring devices arranged between them, and a barb for locking the barbing bar is provided on the upper part of the frame main body. Temporary furnace lid (Japanese Utility Model Laid-Open No. 62-64745) provided with a presser metal that is detachably locked, a lid body formed so that the kiln opening can be sealed similarly to the furnace lid, and a door that can be opened and closed or detached. A provisional furnace lid (Japanese Utility Model Laid-Open No. 62-70148) provided with a plurality of repair windows each having an opening and an engaging device for detachably hooking the lid main body to the kiln opening has been proposed. .
