본 발명은 유연탄을 건류시키는 과정에서 생성되는 타르를 제거하기 위한 장치에 관한 것으로, 특히 코크스오븐 도어의 하부에 설치된 타르받이에 고착되는 타르를 제거하기 위한 장치에 관한 것이다.The present invention relates to an apparatus for removing tar generated in the process of carbonizing bituminous coal, and more particularly, to an apparatus for removing tar stuck to a tar tray installed under a coke oven door.

통상, 혼합된 유연탄을 코크스오븐에 장입시켜 일정시간(약 1200도) 동안 유지시킨 다음 장시간 건류를 시키게 되면 고품질의 고로 열원인 코크스가 생성되게 된다.In general, when the mixed bituminous coal is charged into a coke oven and maintained for a predetermined time (about 1200 degrees) and then dried for a long time, high quality blast furnace heat source coke is produced.

이러한 건류과정을 통해 완성된 코크스를 열원으로 사용하기 위해 코크스오븐에 부착된 도어를 탈착시킨 후 코크스오븐으로부터 인출하게 되는 바, 이때 코크스오븐가스중에 포함되어 있던 타르 성분이 코크스오븐의 도어 하부에 구비된 타르받이에 고착되게 된다.In order to use the coke completed as a heat source through the drying process, the door attached to the coke oven is detached and drawn out from the coke oven. At this time, the tar component contained in the coke oven gas is provided at the bottom of the door of the coke oven. It will stick to the tarband.

상기 타르받이에 고착된 타르는 제거되지 않게 되면 도어를 장착시킬 때에 고착물이 도어와 코크스오븐 본체 사이에 끼이게 되어 도어를 정상적으로 밀착시킬 수 없게 되고, 이로 인해 코크스오븐 내부의 가스가 누설되면서 온도관리의 불량은 물론 막대한 환경오염을 초래하게 된다.If the tar stuck to the tarbasket is not removed, the fixture may be caught between the door and the coke oven body when the door is mounted, thereby preventing the door from coming into close contact with each other. Poor management leads to enormous environmental pollution.

종래에는 이와 같은 고착물을 제거하기 위해 작업자가 콘크리트 타설기 혹은 해머들릴을 사용하여 일일이 수작업처리하여 제거하였다.Conventionally, in order to remove such a deposit, the worker removes by manually processing by using a concrete placing machine or a hammerdrill.

따라서, 작업피로도의 증대는 물론 작업시간이 길어지고 안전사고의 위험이 높아 작업기피 현상과 생산성 저하를 초래하였다.Therefore, as well as the increase in work fatigue, the work time is long and the risk of safety accident is high, resulting in work evasion phenomenon and productivity decrease.

본 발명은 상술한 바와 같은 종래 기술이 갖는 제반 문제점을 감안하여 이를 해결하고자 창출한 것으로, 코크스오븐의 하부에 구비된 타르받이의 근처에 레일을 배설하고, 이 레일을 따라 슬라이딩 왕복가능한 스크래퍼를 구비하여 타르받이에 고착된 이물을 기계적 수단으로 제거처리할 수 있도록 한 코크스오븐 도어 하부 타르받이의 고착물 제거장치를 제공함에 그 목적이 있다. The present invention has been made in view of the above-described problems of the prior art, and has been created to solve this problem. It is an object of the present invention to provide a device for removing the deposit of the tarbasket under the coke oven door which can remove the foreign matter stuck to the tarbasket by a mechanical means.

본 발명의 상기한 목적은 코크스오븐 도어를 장탈착시키는 이동차의 하단 선측에 상향경사지게 배설된 본체베이스와; 상기 본체베이스의 상면에 배설된 가이드레일과; 상기 가이드레일을 따라 슬라이딩가능하게 고정된 작동블럭과; 상기 작동블럭에 연결고정된 작동플레이트와; 상기 작동플레이트의 일단에 고정되고 이를 전후진시키도록 구비된 메인작동실린더와; 상기 작동플레이트의 타단에 고정된 스크래퍼를 포함하여 구성되는 것을 특징으로 하는 코크스오븐 도어 하부 타르받이의 고착물 제거장치를 제공함에 의해 달성된다.The above object of the present invention and the main body is disposed to be inclined upwardly to the bottom side of the bottom of the moving car for removing the coke oven door; A guide rail disposed on an upper surface of the main body base; An operation block slidably fixed along the guide rail; An operation plate fixed to the operation block; A main operation cylinder fixed to one end of the operation plate and provided to advance back and forth; It is achieved by providing a device for removing the deposit of the bottom tarb of the coke oven door, characterized in that it comprises a scraper fixed to the other end of the operation plate.

이하에서는, 첨부도면을 참고하여 본 발명을 보다 상세하게 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

도 1은 본 발명 장치의 설치상태도이고, 도 2는 본 발명 장치의 조립상태를 보인 외관사시도이며, 도 3은 본 발명 장치의 분해사시도이고, 도 4 및 도 5는 본 발명 장치의 작동상태도이다.1 is an installation state diagram of the device of the present invention, Figure 2 is an external perspective view showing the assembled state of the device of the present invention, Figure 3 is an exploded perspective view of the device of the present invention, Figures 4 and 5 is an operating state diagram of the device of the present invention. .

In FIG. 1, the apparatus of the present invention is installed to correspond to the installation angle of the tar tray 4 at the lower side of the tar tray 4 provided at the lower end of the door 2 which seals the open surface of the coke oven 1. .                     

본 발명에 따른 제거장치(10)는 도 2 및 도 3에서와 같이, 이동차(도 1의 '3')의 하단에 고정되고, 상기 타르받이(4)와 동일한 경사를 갖도록 배치된 본체케이스(12)와, 상기 본체케이스(12)의 상면에 그 길이방향을 따라 배설된 가이드레일(14)과, 상기 가이드레일(14)을 따라 이동가능하게 설치된 작동블럭(16)과, 상기 작동블럭(16)을 이동시키는 메인작동실린더(20)와, 상기 메인작동실린더(20)에 의해 전후진되도록 연결부재들에 의해 상기 작동블럭(16)과 연결된 스크래퍼(30)로 구성된다.2 and 3, the removal device 10 according to the present invention is fixed to the lower end of the moving vehicle ('3' of FIG. 1), the main body case is disposed to have the same inclination as the tar receiving 4 (12), a guide rail 14 disposed along the longitudinal direction on the upper surface of the main body case 12, an operation block 16 installed to be movable along the guide rail 14, and the operation block It consists of a main operation cylinder 20 for moving the 16 and the scraper 30 connected to the operation block 16 by connecting members to be advanced back and forth by the main operation cylinder 20.

작동플레이트(22)의 일단은 고정핀(24a)에 의해 상기 메인작동실린더(20)의 실린더로드(26)와 연결고정되고, 타단은 고정핀(24b)에 의해 스크래퍼(30)와 유동가능하게 핀고정된다.One end of the operation plate 22 is fixed to the cylinder rod 26 of the main operation cylinder 20 by a fixing pin 24a, and the other end is movable with the scraper 30 by the fixing pin 24b. Pin is fixed.

메인작동실린더(20)는 고정대(28)상에 견고히 안착되는 바, 상기 고정대(28)는 상기 본체베이스(12)의 상면 일부에 상기 가이드레일(14)과 간섭되지 않도록 고정배치된다.The main operation cylinder 20 is firmly seated on the holder 28, and the holder 28 is fixedly disposed so as not to interfere with the guide rail 14 on a part of the upper surface of the main base 12.

한편, 상기 작동플레이트(22)의 길이 일부 상면에는 'ㄱ'형상의 보조연결대(42)가 연결고정되고, 상기 보조연결대(42)의 단부에는 보조작동실린더(40)가 고정핀(24c)에 의해 유동가능하게 핀고정된다.On the other hand, the upper part of the length of the operation plate 22 'b' shaped auxiliary connector 42 is fixed to the connection, the auxiliary operation cylinder 40 at the end of the auxiliary connector 42 is fixed pin 24c Are pinned to be movable.

상기 보조작동실린더(40)의 선단측인 실린더로드(46)의 단부에는 고정핀(24d)에 의해 연결브라켓(44)의 상단과 힌지연결되고, 상기 연결브라켓(44)의 하단은 상기 스크래퍼(30)의 상면에 입설된다.The upper end of the connecting bracket 44 is hinged to the end of the cylinder rod 46, which is the front end of the auxiliary operation cylinder 40 by a fixing pin 24d, and the lower end of the connecting bracket 44 is the scraper ( 30) is placed on the upper surface.

따라서, 상기 연결브라켓(44)은 스크래퍼(30) 및 실린더로드(46)와 각각 직 교되는 형태로 연결설치된다.Therefore, the connection bracket 44 is installed in a form orthogonal to the scraper 30 and the cylinder rod 46, respectively.

이러한 구성으로 이루어진 본 발명의 작동관계는 다음과 같다.The operating relationship of the present invention made of such a configuration is as follows.

도 1 내지 도 5를 참조하면, 유연탄을 건류시키는 과정에서 코크스오븐 가스중에 함유되어 있던 타르성분이 타르받이(4)에 쌓여 고착되게 된다.1 to 5, in the process of carbonizing bituminous coal, tar components contained in the coke oven gas are accumulated and fixed in the tar tray 4.

일정주기가 되면 혹은 작업자의 선택에 따라 메인작동실린더(20)를 전진시키게 되면 그와 링크된 작동플레이트(22)가 가이드레일(14)을 따라 안내되는 작동블럭(16)과 함께 안정적으로 전진작동하게 된다.When the main operation cylinder 20 is advanced at a predetermined period or at the operator's choice, the operation plate 22 linked thereto is stably moved forward with the operation block 16 guided along the guide rail 14. Done.

상기 작동플레이트(22)의 전진작동에 따라 그와 연결된 스크래퍼(30)가 타르받이(4)의 바닥면을 긁어주면서 상향이동되어 고착된 타르를 제거하게 된다.According to the forward operation of the operation plate 22, the scraper 30 connected thereto removes the tar stuck to the bottom surface of the tar receiving 4 while moving upward.

만약, 타르받이(4)의 경사도와 스크래퍼(30)의 배치상태가 일치되지 않을 경우에는 메인작동실린더(20)를 작동시키기 전에 먼저 보조작동실린더(400를 전후진시키면서 도 4 혹은 도 5에서와 같이, 스크래퍼(30)의 회전각을 조절하여 타르받이(4)의 경사도에 맞게 일치시킨 다음 상술한 스크래핑 작업을 수행하게 되면 고착물이 긁어지면서 고착상태가 해소되어 타르받이(4)로부터 제거되게 된다.If the inclination of the tar tray 4 and the arrangement of the scraper 30 do not coincide with each other, the auxiliary operation cylinder 400 may be moved back and forth before the main operation cylinder 20 is operated. Likewise, by adjusting the rotation angle of the scraper 30 to match the inclination of the tar tray 4, and then performing the above-described scraping operation, the seizure is scratched and the seizure is resolved to be removed from the tar tray 4 do.
