Repair apparatus for coke oven

Abstract

A repair apparatus for a coke oven, comprising a traveling carriage (3) put across rails laid down on the coke oven and traveling in the direction of the furnace group of the coke oven. A transverse carriage (4) moving in a direction orthogonal to the traveling direction is installed on the traveling carriage (3). A work device (5) for repairing a furnace wall on the inside of the coke oven is mounted on the transverse carriage (4). The work device (5) is characterized by comprising a guide post (31) vertically installed on the transverse carriage (4) and having a lower end part connected, through a pivot shaft (42), to a support part formed on the transverse carriage, a lance (32) lifting along the guide post (31), and a derricking device (45) swinging the lance (32) inserted through an insert hole into a coke oven carbonization chamber in a furnace length direction by swinging the guide post (31) about the pivot shaft (42) between a forward tilted attitude and a backward tilted attitude.

Description

technical field [0001] The present invention relates to a repairing device for a coke oven suitable for repairing the inner wall of the coke oven. Background technique [0002] The coke furnace is composed of a structure in which the carbonization chamber and the combustion chamber formed by refractory bricks are alternately arranged in the direction of the furnace group (Japanese: furnace direction), and the heat of the combustion chamber is transferred to the carbonization chamber through the refractory bricks. The coal in the carbonization chamber is dry-distilled to produce coke. In addition, the coal loading into the carbonization chamber is carried out by the coal loading car on the coke oven running along the direction of the furnace group. [0003] Although most of these coke ovens are aging after 30 years since the furnace was built, it requires a huge investment and a long-term construction period to rebuild the equipment of a huge coke ove...

AI Technical Summary

Problems solved by technology

[0010] If the above-mentioned repairing device 107 is arranged on both the coke side (coke receiving (Japanese: コククス accepting) side) and the machine side (coke side), although it is theoretically possible to repair the entire furnace, it is possible to put in multiple large, Costly patching device 107 is impractical

In addition, since the repairing device 107 usually travels on the track on which the working device travels, there is a problem that if the repairing is given priority, the working device must be kept on standby, so the operating rate of the coke oven is reduced; The repairing device 107 is frequently avoided, and the repairing efficiency is reduced

[0015] However, since the spray gun 127 is lowered through a narrow insertion hole with a diameter of about 40 to 50 cm, in the repair device 120 that lowers the spray gun 127, the repair range is limited to the vicinity of the lowering path of the spray gun 127.

[0016] In this way, in the existing repairing devices 107, 120, no matter which method it is, it is impossible to avoid remaining areas that cannot be repaired on the furnace wall.
