본 고안은 코크스로 연와보수용 작업도어에 관한 것으로, 특히 세라믹웰딩(Ceramic Welding)을 위해 코크스로의 도어를 개방시에 코크스로의 표면온도 저하를 방지하여 내장연와가 양호한 상태로 보수될 수 있도록 한 것이다.The present invention relates to a work door for repairing coke furnace softening, and in particular, to prevent the internal temperature of the coke oven from being lowered when opening the door of the coke oven for ceramic welding, so that the built-in softener can be repaired in good condition. It is.
일반적인 코크스로는 제1도에서와 같이, 혼합가스분배관(1)에서 분해공급된 가스가 가스코크(2)로 개폐되는 가스공급관(3)을 통해 소올플루(Sole Plue : 4)와 노즐플레이트(5)를 따라 연소실(6)로 공급되고, 연소실(6)에 공급된 가스가 연소 됨에 따라 그열이 내장연와(규소연와)로 축조된 탄화실(7)로 전도되어 장입된 유연탄을 건류시키도록 하며, 연소가스는 폐기변(8)을 통해 소연도(9)로 배출안내되도록 구성되어 있다.As a general coke furnace, as shown in FIG. 1, a sool flue (4) and a nozzle plate are provided through a gas supply pipe 3 through which the gas supplied from the mixed gas distribution pipe 1 is opened and closed by the gas scope 2, as shown in FIG. (5) is supplied to the combustion chamber (6), and as the gas supplied to the combustion chamber (6) is burned, its heat is conducted to the carbonization chamber (7) constructed with the internal combustion (silicon) and carbonized coal charged carbon. Combustion gas is configured to be discharged to the small flue (9) through the waste stool (8).
여기에서, 상기 탄화실(7)을 구성하는 내장연와는 유연탄을 장입. 배출시키는 압출기의 작동충격에 의해 균열, 파손, 목지부분의 손상이 발생되며, 이 경우 유연탄 건류시의 생성가스가 손상부위로 누출되어 연소실(7)로 들어가 불완전 연소를 발생시키게 됨으로써 발생가스의 손실은 물론 코크스로의 온도관리를 저해하게 되므로 손상된 내장연와는 즉각적인 보수가 요구된다.Here, the coal briquettes which constitute the carbonization chamber 7 are charged with bituminous coal. Cracks, breakage, and damage to wood parts are generated by the operating impact of the extruder to discharge.In this case, the gas generated during bituminous coal distillation leaks into the damaged part and enters the combustion chamber (7), resulting in incomplete combustion. Of course, it will impede the temperature control of the coke oven, so damaged repairs require immediate repair.
상기한 보수작업은 내장연와의 손상부위에 실시되는 세라믹웰딩에 의해 안료되는데, 세라믹웰딩의 용착성 증대를 위해서는 필수적으로 코크스 로벽의 온도를 800℃정도로 유지해야 하나, 보스작업을 위해 코크스로의 도어를 개방시킬 경우 탄화실(7)의 온도는 요구온도 보다 훨씬 낮은 600℃ 이하로 저하되어 양호한 시공체를 얻을 수 없게 된다.The repair work is pigmented by ceramic welding performed on the damaged part with the built-in lead. In order to increase the weldability of the ceramic welding, the temperature of the coke oven wall must be maintained at about 800 ° C. When the temperature of the carbonization chamber 7 is opened, the temperature of the carbonization chamber 7 is lowered to 600 ° C. or lower, which is much lower than the required temperature, so that a good construction body cannot be obtained.
즉, 보수작업의 진행시에 코크스로의 온도가 낮을 경우 용융상태가 불량하고 기공이 형성되며 접착불량에 의한 조기탈락의 근본요인을 제공하게 되므로 내장연와의 보온은 필수적으로 요구된다. 그런데 종래에는 제2도에서와 같이 탄화실(7)의 내장연와(7a)에 발생된 손상부위(d)를 보수하기 위해 도어프레임(10)에 조립된 도어를 개방시키고 방열판(11)을 손상부위(d)의 내부까지 밀어넣어 손상부위(d)가 노출되도록 하여 부수작업을 진행시켰다.In other words, when the temperature of the coke oven is low during the maintenance work, the molten state is poor, the pores are formed, and the basic factor of premature dropout due to poor adhesion is required. However, in the related art, as shown in FIG. 2, the door assembled in the door frame 10 is opened to damage the heat-generating edge 7a of the carbonization chamber 7 and the heat sink 11 is damaged. Pushed to the inside of the site (d) to expose the damaged site (d) to proceed with the secondary work.
그러나 이러한 종래 보수방법은 방열판.However, this conventional repair method is a heat sink.
(11)의 설치가 어렵고 설치작업에 많은 시간이 소요되는 문제점이 있으며, 따라서 통상적으로는 방열판(11)의 설치를 생략, 즉 탄화실(7)을 개방시킨 상태에서 보수작업을 수행하고 있으므로 코크스로 벽의 급격한 냉각으로 인해 전기한 보수제 탈락등의 문제점이 발생되고 있다.There is a problem that the installation of (11) is difficult and takes a lot of time for the installation work, and therefore, the installation of the heat sink 11 is omitted, that is, the maintenance work is performed in the state where the carbonization chamber 7 is opened. Sudden cooling of the furnace walls has caused problems such as the removal of the repairing agent.
본 고안은 상기한 문제점들은 적극적으로 해소시킬 수 있는 코크스로 연와보수용 작업도어를 제공함에 그 목적이 있는바, 이하에서 본 고안의 양호한 실시예를 첨부도면에 의해 설명한다.The present invention is intended to provide a work door for repairing the coke oven coke that can actively solve the above problems, the following describes a preferred embodiment of the present invention by the accompanying drawings.

이와 같은 구성의 본 고안작업도어(W)는 탄화실(7)의 내장연와(7a)에 손상부위(d)가 발생되어 보수가 요구될 경우, 우선 도어프레임(10)에 설치된 작업용 도어(도시되지 않음)를 분리시키고 이동수단에 적재시킨 작업용 도어(W)를 도어프레임(10)에 설치하게 된다.The work door (W) of the present invention having such a configuration has a damage part (d) generated in the interior edge (7a) of the carbonization chamber (7). Not)) and the working door W loaded on the moving means is installed in the door frame 10.
이때, 우선 본체(12) 하단의 지지판(12a)을 도어프레임(10)의 하부상면에 지지되도록 삽입시킨 상태에서 도어프레임(10)의 걸림부(10a)에 래치바(11)를 걸어주게 되면, 본체(12)는 그 양측에 구비된 가압기구부(13)의 가압축(21)이 래치바(11)에 가압되어 탄성부재(22)를 압축시키며 이동한 상태가 된다.At this time, when the latch bar 11 is hung on the locking portion 10a of the door frame 10 while the support plate 12a at the bottom of the main body 12 is inserted to be supported on the lower upper surface of the door frame 10. The main body 12 is in a state in which the pressing shaft 21 of the pressing mechanism 13 provided at both sides thereof is pressed by the latch bar 11 to compress and compress the elastic member 22.
따라서 가압기구부(13)의 홀더(17)외면에 구비된 고정판(14)에 볼트체결 고정된 본체(12)는 탄성부재(22)의 인장복귀력에 의해 도어 프레임(10)과 가압저촉된 상태가 되며(제6도 참조), 본체(12)의 밀착력 즉 탄성부재(22)의 장력조정은 홀더(17)후방의 조정나사부(16)에 나사결합된 조정너트(23)를 진퇴이동시킴으로써 신속용이하게 이루어진다.Therefore, the main body 12, which is bolted to the fixing plate 14 provided on the outer surface of the holder 17 of the pressing mechanism 13, is pressed against the door frame 10 by the tension return force of the elastic member 22.
