본 발명은 석탄선별장치에 관한 것으로, 더욱 상세하게는 화력발전소에서 석탄을 선별하기 위해 사용되는 석탄선별장치의 2차 스크린을 안전하고 쉽게 교체할 수 있도록 하기 위한 석탄선별장치에 관한 것이다.The present invention relates to a coal sorting device, and more particularly, to a coal sorting device for safely and easily replace the secondary screen of the coal sorting device used for sorting coal in a thermal power plant.

석탄을 연료로 하는 곳, 특히 화력 발전소 등에서는 석탄 유동층 보일러를 사용하게 되는데, 상기 보일러에 의해 석탄을 연소시켜 물을 고온, 고압의 증기로 만든 후에 이 증기의 힘으로 터빈을 회전시켜 축에 연결된 발전기로부터 전기를 생산하게 된다. 이때 상기 유동층 보일러 석탄 입자들과 석탄, 석회석, 회(Ash) 등과 같은 유동매체의 혼합 가루층에 적정 속도의 공기를 불어 넣어 석탄과 유동매체 혼합물을 부유 유동층(Suspended Fluidizing Bed) 상태로 만들어 연소시키는 방식을 사용하고 있다.Where coal is used as fuel, especially coal-fired power plants, coal fluidized bed boilers are used. The coal is burned by the boiler to produce water at high temperature and high pressure. It will produce electricity from the generator. At this time, by blowing the air at a suitable speed to the mixed powder bed of the fluidized bed boiler coal particles and the fluidized medium such as coal, limestone, ash (Ash) to make the coal and fluid medium mixture into a suspended fluidizing bed (Suspended Fluidizing Bed) to burn I'm using the method.

따라서 상기 유동층 보일러에 사용하기 적합한 크기의 석탁을 선별할 필요성이 있으며, 이를 위해서 석탄선별장치를 사용하고 있다. 이때 석탄선별장치는 석탄의 크기를 연소시키기 적합한 크기로 만들기 위한 장치로 1차 스크린과 2차 스크린을 구비하는 진동식 석탄선별기가 사용된다.Therefore, there is a need to sort out the turbidity of a size suitable for use in the fluidized bed boiler, for this purpose it uses a coal sorting device. At this time, the coal sorting device is a vibratory coal sorting machine having a primary screen and a secondary screen as a device for making the size of coal suitable for combustion.

그런데 상기 1차 스크린은 석탄선별기의 본체 상부에 설치되고, 2차 스크린은 본체의 내부 중간부에 설치되어 진다. 기존의 2차 스크린 설치방법은 1차 스크린 아래 본체의 양측면에 체결수단에 의해 고정하는 것이어서 2차 스크린이 손상되거나 막히게 되어 석탄 선별 기능이 상실되었다 하더라도 이를 교체 해주기란 쉬운 일이 아니다. 왜냐하면 상기 석탄선별기는 슈트 위에 설치되어 지는 것이어서 상당한 높이에서 작업이 이루어지는 것이어서 안전사고의 우려가 크고, 2차 스크린의 크기와 중량 때문에 작업자가 본체 내부에 들어가서 이를 꺼내기란 결코 용이한 일이 아니기 때문이다.By the way, the primary screen is installed on the upper part of the main body of the coal sorter, the secondary screen is installed in the inner middle of the main body. Conventional secondary screen installation method is fixed by the fastening means on both sides of the main body under the primary screen, it is not easy to replace even if the secondary screen is damaged or blocked because the coal screening function is lost. Because the coal sorter is installed on the chute, the work is performed at a considerable height, so there is a risk of safety accident, and because of the size and weight of the secondary screen, it is never easy for the worker to enter the body and take it out. .

따라서 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 본 발명은 석탄선별장치 본체의 내부 중간부에 설치되는 2차 스크린을 본체 외부로 꺼내서 수리하거나 교체할 수 있도록 함으로써 작업을 편리하게 할 수 있도록 하였으며, 작업자의 안전사고를 줄일 수 있는 석탄선별장치를 제공함에 그 목적이 있다.Therefore, the present invention has been made to solve the above problems, the present invention is to facilitate the work by allowing the secondary screen installed in the inner middle portion of the coal sorting device body to be taken out to repair or replace. The purpose is to provide a coal sorting device that can reduce the safety accidents of workers.

상기의 목적을 갖는 본 발명을 이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, the present invention having the above object will be described in detail with reference to the accompanying drawings.

본 발명 석탄선별장치(100)는 본체(110)와, 상기 본체(110) 상부에 설치되는 1차 스크린(120)과, 본체의 내부 중간부에 설치되는 2차 스크린(140)으로 이루어진다. 이때 2차 스크린(140)을 본체(110) 외부로 꺼낼 수 있도록 하기 위하여 본체(110)의 내부 측면에 레일(111)을 형성하고 상기 레일(111)을 타고 이동할 수 있는 바퀴(131a)를 구비하는 대차(130)가 설치되어 지는데, 상기 대차(130)는 한 쌍의 프레임(131)과 상기 프레임(131)의 사이에 설치되고 양 측면에 고정구 삽입공(131c)이 형성된 2차 스크린 받침대(131b)와, 상기 2차 스크린 받침대(131b) 위에 얹혀 프레임(131)에 2차 스크린 결합구(141)에 의해 결합되는 2차 스크린(140)으로 이루어진다.The coal sorting apparatus 100 of the present invention includes a main body 110, a primary screen 120 installed on the main body 110, and a secondary screen 140 installed on an inner middle portion of the main body. In this case, in order to allow the secondary screen 140 to be taken out of the main body 110, a rail 111 is formed on an inner side surface of the main body 110 and provided with wheels 131a that can move on the rail 111. The cart 130 is installed, the cart 130 is installed between the pair of frames 131 and the frame 131, the secondary screen pedestal formed with the fastener insertion hole (131c) on both sides ( 131b and a secondary screen 140 mounted on the secondary screen pedestal 131b and coupled to the frame 131 by a secondary screen coupler 141.

상기 대차(130)는 대차결합부(132)에 의해 본체(110)와 분리가능하도록 결합되어 지는데, 상기 대차결합부(132)의 구성은 다음과 같다.The balance 130 is coupled to the body 110 by the balance coupling portion 132 to be detachable, the configuration of the balance coupling portion 132 is as follows.

본체(110)의 외측에 고정구 체결볼트(132d)에 의해 결합되어 지는 대차결합구(132a)와, 상기 대차결합구(132a)를 관통한 다음 2차 스크린 받침대(131b)의 고정구 삽입공(131c)에 삽입되어 지는 프레임 고정구(132b)와, 상기 프레임 고정구(132b)가 본체(110)로부터 이탈되는 것을 방지하기 위한 고정구 체결부재(132c)로 이루어진다.A bogie coupling hole 132a coupled to the outside of the main body 110 by a fastener fastening bolt 132d and a bogie insertion hole 131c of the secondary screen pedestal 131b after passing through the bogie coupling hole 132a. Frame fastener 132b to be inserted into the) and the fastener fastening member 132c for preventing the frame fastener 132b from being separated from the main body 110.

상기 고정구 체결부재(132c)는 고정구 삽입공(131c)에 나사결합되는 축의 구조를 갖는다.The fixture fastening member 132c has a shaft structure that is screwed into the fixture insertion hole 131c.

또한 상기 대차(130)는 다수 개로 나누어 형성함이 바람직하며, 이들 대차(130)는 대차 연결구(150)에 의해 연결되도록 한다. 이때 후방에 위치한 대차의 끝단에는 윈치 또는 견인장치로 끌어당기기 위한 미도시된 고리를 형성할 수도 있 다. In addition, the balance 130 is preferably formed by dividing into a plurality, the balance 130 is to be connected by the balance connector (150). At this time, the end of the bogie located in the rear may form a ring not shown for pulling to the winch or towing device.

상기와 같은 구조를 갖는 본 발명 석탄선별장치(100)의 작용효과는 다음과 같다.Effects of the present invention coal selection device 100 having a structure as described above are as follows.

먼저 각각의 대차(130)를 본체(110)의 내부 중간부에 형성된 레일(111)에 얹고 이들을 대차 연결구(150)로 연결하면서 순차적으로 밀어넣게 된다. First, each trolley 130 is placed on the rail 111 formed in the inner middle portion of the main body 110 and is sequentially pushed while connecting them with the bogie connector 150.

상기 대차(130)가 제자리에 위치하게 되면 2차 스크린 받침대(131b)에 형성된 고정구 삽입공(131c)에 프레임 고정구(132b)가 삽입되도록 한다. 상기 프레임 고정구(132b)는 대차결합구(132a)에 의해 본체(110)에 결합된 상태이고, 고정구 체결부재(132c)에 의해 고정된 상태이다.When the cart 130 is in place, the frame fixture 132b is inserted into the fixture insertion hole 131c formed in the secondary screen pedestal 131b. The frame fixture 132b is coupled to the main body 110 by the balance coupler 132a and is fixed by the fixture fastening member 132c.

따라서 상기 프레임 고정구(132b)만 분리시키게 되면 결국 대차(130)가 본체(110)로부터 분리되는 구조여서 본체(110)의 후방에서 상기 대차(130)의 일측을 미도시된 견인장치로 잡아당기게 되면 대차(130)가 레일(111)을 타고 본체(110) 외부로 노출가능하게 되며, 따라서 대차(130) 위에 얹혀있는 2차 스크린(140)의 교체 및 수리가 매우 용이하게 되는 것이다.Therefore, when only the frame fixture 132b is separated, the trolley 130 is separated from the main body 110 so that one side of the trolley 130 is pulled from the rear of the main body 110 by a traction device not shown. The trolley 130 may be exposed to the outside of the main body 110 on the rail 111, and thus the replacement and repair of the secondary screen 140 mounted on the trolley 130 becomes very easy.

이처럼 본 발명은 본 발명이 속하는 분야의 당업자는 첨부된 청구범위에 기재된 본 발명의 사상 및 요지로부터 벗어나지 않고 얼마든지 본 발명에 대한 수정 및 변경을 가할 수 있다는 것은 당연하다고 할 것이다.As such, it will be apparent to those skilled in the art that the present invention may be modified and changed as many as possible without departing from the spirit and the gist of the present invention as set forth in the appended claims.

이처럼 본 발명은 석탄선별기 본체의 내부 중간부에 설치되는 2차 스크린을 본체 외부로 꺼내서 수리하거나 교체할 수 있도록 함으로써 작업을 편리하게 할 수 있도록 하였으며, 작업자의 안전사고를 줄일 수 있는 매우 유용한 발명인 것이다.As described above, the present invention makes it easy to work by removing the secondary screen installed in the inner middle portion of the coal sorter main body to the outside of the main body and repairing or replacing it, which is a very useful invention that can reduce the safety accident of the worker. .
