본 고안은 일반 채석장등에서 암석을 채석하기 위하여 암석을 절단내지는 절삭할때 사용하는 젯트 분사식 오일 버어너에 관한 것으로, 특히 연료 예열실을 젯트 분사식 오일 버어너 몸체 내에 형성하여 연소시 발생하는 연소열을 이용하여 연료가 분사되기 직전에 예열되도록 한 암석절단용 젯트 분사식 오일 버어너에 관한 것이다.The present invention relates to a jet injection oil burner used for cutting or cutting a rock in order to quarry rock in a general quarry. In particular, a fuel preheating chamber is formed in the jet injection oil burner body to utilize combustion heat generated during combustion. The present invention relates to a jetting oil burner for rock cutting which is preheated just before fuel is injected.

일반적으로 암석 절단용 젯트 분사식 오일 버어너(이하 버어너라함)에 주로 사용하는 연료는 경비 절감을 위하여 점도가 높은 경유나 중유를 사용한다.In general, the fuel mainly used for jetting jet oil burners (hereinafter referred to as burners) for rock cutting uses high-viscosity diesel oil or heavy oil for cost reduction.

그런데 종래 이런 종류의 버어너(1)는, 제7도에 도시한 바와같이, 전방의 화구몸체(제7도에는 도시 생략)와 다수의 통공(4)을 보유하는 혼합실(5)이 형성된 고정체(6) 사이에 연소실(26)을 구성하는 내.외부 통기관(8)(8')을 용착하고 그 외측에 끼워 붙인 전후방 대류관(9)(9')을 연결관(11)으로 연결하여 내.외측 공기통로 (16)(16')를 형성하고, 상기 고정체(6)에는 송유관(15)과 노즐(13)을 연결설치한 것으로 상기 송유관(15)과 노즐(13)에서 분출되는 연료유와 내.외측 공기통로 (16)(16')를 통해 공급되는 공기를 연소실(26)에서 혼합 연소시키는 것이다.By the way, this type of burner 1 is conventionally formed with a mixing chamber 5 having a front crater body (not shown in FIG. 7) and a plurality of through holes 4, as shown in FIG. The front and rear convection pipes 9 and 9 'welded to the outer and outer vent pipes 8 and 8' constituting the combustion chamber 26 between the stationary bodies 6 and the fitting pipes 11 are connected to the connection pipe 11. The inner and outer air passages (16, 16 ') are connected to each other, and the oil supply pipe (15) and the nozzle (13) are connected to and installed in the fixed body (6). The fuel oil ejected and the air supplied through the inner and outer air passages 16 and 16 'are mixed and combusted in the combustion chamber 26.

그러나 이러한 종래의 버어너에서는, 공기는 공기통로(16)(16')에서 예열되어 공급되지만 연료유는 예열되지 않은 상태로 분사되므로 분사상태가 양호치 못하고 연료입자가 크기 때문에 연소실내에 분사되였을때 분산성이 나빠지고 착화가 지연되는 등의 큰 영향을 미치게되며, 또한 불완전 연소로 인하여 연료 소비량이 증대될 뿐만 아니라 작업능률이 저하된다.However, in such a conventional burner, air is preheated and supplied in the air passages 16 and 16 ', but the fuel oil is injected without being preheated, so that the injection state is not good and the fuel particles are large so that they are injected into the combustion chamber. This results in poor dispersibility and delayed ignition. In addition, incomplete combustion increases fuel consumption and lowers work efficiency.

따라서 제8도에 도시한 바와같이, 연료를 공급하는 연료탱크 및 연료 압축이송 펌프와 점화시 사용되는 산소탱크와 압축공기를 발생시켜 공급하는 콤프레샤 외에 연료를 예열하는 예열기를 별도 설치하여 사용하였다.Therefore, as shown in FIG. 8, a fuel tank for supplying fuel, a fuel compression transfer pump, an oxygen tank used for ignition, and a compressor for generating and supplying compressed air in addition to a compressor for generating and supplying fuel were used separately.

그러나 한대지방이나 겨울 등 주위 온도가 낮을때는 부대시설(연료탱크, 예열기, 콤프레샤 등)과 먼 거리에서 버어너를 사용할 때 연료가 예열되어 송유되는 동안에 예열된 연료 온도가 떨어져 착회된 불꽃이 자주 꺼지는 결점이 있을 뿐만 아니라, 제작비와 설치비가 고가이며 또한 예열기에 별도의 열원을 공급하여야 되는 결점이 있었다.However, when the ambient temperature is low, such as in the countryside or winter, when the burner is used at a long distance from the auxiliary facilities (fuel tank, preheater, compressor, etc.), the preheated fuel temperature drops while the fuel is preheated, and the sparks that are often burned out are turned off. In addition to the drawbacks, there was a drawback that the manufacturing and installation costs were expensive and a separate heat source had to be supplied to the preheater.

따라서 본 고안은 전술한 바와같은 종래의 결저믈 해소키 위하여 안출한 것으로 별도의 연료유 예열기를 설치할 필요없이 버어너 자체내에서 예열하여 분사토록 함으로써 연료유의 연소효율을 높여 연료 소비량을 저감시킬수 있으며, 작업능률이 향상시킬수 있고, 별도의 예열기를 사용하지 않는 만큼 설치비 및 운영비를 절감할수 있으며, 구조가 간단하여 염가로 공급할수 있도록한 암석 절단용 젯트 분사식 오일버어너를 제공하려는 것이다.Therefore, the present invention has been devised to solve the conventional problems as described above, and it is possible to reduce the fuel consumption by increasing the combustion efficiency of fuel oil by preheating and injecting it in the burner itself without installing a separate fuel oil preheater. It is to provide a jet injection oil burner for rock cutting that can improve work efficiency, reduce installation cost and operation cost by not using a separate preheater, and have a simple structure to supply cheaply.

이하 본 고안을 첨부 도면에 따라서 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 고안의 암석 절단용 젯트 분사식 오일 버어너는 제1도 내지 제6도에 도시한 바와같이 화염 분출공(2)이 천설된 화구몸체(3)와 , 다수의 통공(4)과 관통되어 있는 혼합실(5)이 형성된 고정체(6)사이에, 다수의 돌기편(7)(7')이 돌설된 내부 통기관(8)과 외부통기관(8')을 용가하고, 그 외측에 설착된 전방 대류관(9)과, 산소분사관(10)이 내설된 후방 대류관(9')을 연결관(11)으로 연결하여서된 통상의 젯트 분사식 오일 버어너(1)있어서, 상기 고정체(6)의 후미에 가열부(6')를 일체로 형성하고, 상기 송유관(14)의 선단부에는 노즐(13)이 부착되는 접열부(接熱部) (14″)를 형성하며 그 후방으로 확장된 연료예열실(14')을 형성하여 상기 고정체(6)의 나사공(12)에 나사 부착하여 상기 고정체(6) 선단과 접열부(14″) 사이에 접열공간 (15)을 형성한 것이다.The jet cutting oil burner for rock cutting according to the present invention has a fireball body (3) in which a flame ejection hole (2) is laid, and a plurality of through holes (4) are penetrated, as shown in FIGS. Between the stationary body 6 in which the mixing chamber 5 was formed, the inner vent pipe 8 and the outer vent pipe 8 'in which the plurality of projection pieces 7, 7' protrude, are forged, and are installed on the outside thereof. There is a conventional jet injection oil burner (1) which connects the front convection pipe (9) and the rear convection pipe (9 ') in which the oxygen injection pipe (10) is installed by a connecting pipe (11), The heating part 6 'is integrally formed at the rear end of 6), and at the distal end portion of the oil pipe 14, a heat connection part 14 ″ to which the nozzle 13 is attached is formed and extended to the rear part thereof. A fuel preheating chamber 14 'was formed and screwed to the screw hole 12 of the fixture 6 to form a heat-sealing space 15 between the tip of the fixture 6 and the contact portion 14 ″. will be.

그리고 내부 통기관(8)은 화구몸체(3) 후미면과 고정체(6) 전단면에 용착하고, 외부 통기관(8')은 고정체(6)중간 부위에만 용착하여 내외부 통기관(8)(8')외주면에 등간격으로 돌설된 장방향돌조(7)(7')에 의해 내측 공기통로(16)와 외측 공기통로(16')가 형성되도록 하였다.The inner vent pipe 8 is welded to the rear surface of the crater body 3 and the front end of the fixture 6, and the outer vent pipe 8 'is welded only to the middle part of the fixture 6 so that the inner and outer vent pipes 8 and 8 are welded. ') The inner air passage 16 and the outer air passage 16' are formed by the longitudinal protrusions 7 and 7 'protruding at equal intervals on the outer circumferential surface.

도면 중 미설명 부호(17)은 고정너트이고, (18)은 콤퓨레샤 (19)는 압축공기 조절밸브, (20)은 산소탱크, (21)은 연료탱크, (22)는 연료압축펌프, (22')는 모타, (23)은 연료 여과기, (24)는 연료 조절밸브, (25)는 산소 조절밸브, (26)은 연소실이다.In the drawings, reference numeral 17 is a fixing nut, 18 is a compressor 19 is a compressed air control valve, 20 is an oxygen tank, 21 is a fuel tank, and 22 is a fuel compression pump. 22 is the motor, 23 is the fuel filter, 24 is the fuel control valve, 25 is the oxygen control valve, and 26 is the combustion chamber.

이와같이 구성된 본 고안의 작용효과를 설명하면, 연료탱크(21)에 저장된 연료는 연료압축 펌프(22)를 통과하면서 압축되어 송유관(14)을 따라 공급되어 확개된 연료 예열실(14')에 도달하면 잠시 머문 다음 노즐(13)을 통하여 분사되는데 이때 예열실(14')에 연료가 머무는 시간은 노즐(13)의 분사량과 비례한다.Referring to the operation and effect of the present invention configured as described above, the fuel stored in the fuel tank 21 is compressed while passing through the fuel compression pump 22 is supplied along the oil feed pipe 14 to reach the fuel preheating chamber 14 'expanded. If it stays for a while, it is injected through the nozzle 13, where the fuel stays in the preheating chamber 14 'is proportional to the injection amount of the nozzle 13.

그리고 산소 또는 압축공기는 후방대류관(9')을 통해 외측공기통로(16')로 주입하강되고 전방에서 되돌아 내측 공기통로(16)로 상승하게되어 통공(4)을 통해 혼합실(5)로 주입되어 연소실(26)에 이르게 되는데 화구를 점화시키고져 할때는 먼저 산소조절밸브(25)를 개방시켜 산소를 분사시키고, 다음에 연료 조절밸브(24)를 개방하여 압축된 연료를 공급한다.Oxygen or compressed air is injected into the outside air passage 16 'through the rear convection pipe 9' and ascended from the front to the inside air passage 16 so that the mixing chamber 5 through the through hole 4 is provided. When it is injected into the combustion chamber 26, when the fireball is ignited, the oxygen control valve 25 is first opened to inject oxygen, and then the fuel control valve 24 is opened to supply the compressed fuel.

그리고 압축 공기 조절밸브(19)로 압축공기를 조절하여 버어너(1)내에 주입시키고 타불꽃에 의해 화염 분출공(2)에 점화한다.Then, the compressed air is regulated by the compressed air control valve 19 to be injected into the burner 1 and ignited in the flame ejection hole 2 by the other flame.

그리고 화염분출공(2)에 점화가 되면 내외부 통기관(8)(8')이 어느 일정 온도로 상승될 동안 산소를 계속 공급하며, 일정온도로 내외부 통기관(8)(8')이 상승되면 산소조절밸브(25)를 폐쇄하여 산소 공급을 중단시킨다.When the flame ejection hole 2 is ignited, oxygen is continuously supplied while the internal and external vent pipes 8 and 8 'are raised to a certain temperature, and when the internal and external vent pipes 8 and 8' are raised to a predetermined temperature, oxygen is supplied. The control valve 25 is closed to stop the oxygen supply.

따라서 노즐(13)에서 분사되는 연료와 내외측 공기통로(16)(16')를 지나 다수의 통공(4)을 통해 계속 주입되는 압축공기는 혼합실(5)에서 혼합되어 연소실 (26)에서 연소가 되면서 화연분출공(2)로 연소불꽃이 분출되어 암석을 파쇄절단하는 것이다.Therefore, the fuel injected from the nozzle 13 and the compressed air continuously injected through the plurality of through holes 4 through the inner and outer air passages 16 and 16 ′ are mixed in the mixing chamber 5 and mixed in the combustion chamber 26. As it is burned, combustion flame is blown into the combustion jet hole (2) to crush and cut rocks.

이때 버어너(1)내에 주입된 압축공기는 내외측 공기통로(16)(16')를 지나는 동안 연소열에 가열된 내외부 통기관(8)(8')에 의해 압축공기 온도가 상승되어 연소시 불완전 연소를 방지하게 한다.At this time, the compressed air injected into the burner 1 is increased by the internal and external vent pipes 8 and 8 'heated by the combustion heat while passing through the internal and external air passages 16 and 16', resulting in incomplete combustion. Prevents combustion.

또한 상기 고정체(6)의 선단부가, 연소시 발생된 연소실(26)내의 열과 공기통로(16)(16')에서 가열되어 통공(4)을 통해 연소실(26)로 분출되는 공기의 열에 접하게 됨과 아울러 상기 송유관(15)의 선단 접열부(14″)가 연소실(26)과 연통된 접열공간(15)내에서 연소열에 접하여 가열된다.In addition, the front end portion of the fixed body 6 is heated in the combustion chamber 26 generated during combustion and heated in the air passages 16 and 16 'to be in contact with the heat of the air ejected into the combustion chamber 26 through the through hole 4. In addition, the leading end portion 14 ″ of the oil pipe 15 is heated in contact with the heat of combustion in the heat space 15 communicating with the combustion chamber 26.

따라서 고정체(6)와 일체로 형성된 가열부(6')의 온도도 상승하게됨과 아울러 이들 열이 연료 예열실(14')에 전열되어, 노즐(13)에 의해 분사되기 전에 예열실(14')에 잠시 머무는 연료를 가열하게되는 것이다.Therefore, the temperature of the heating portion 6 'formed integrally with the fixture 6 is also raised, and these heats are transferred to the fuel preheating chamber 14' and before being injected by the nozzle 13, the preheating chamber 14 Staying on for a while will heat up the fuel.

그러므로 가열된 연료는 분사기 잘 되어 완전 연소를 할수 있는 것이다.Therefore, the heated fuel is good at the injector, allowing complete combustion.

따라서 본 고안에 의하면 연료를 예열하기 위하여 별도의 예열기를 사용치 않고도 연소효율을 높여 연료소비량 저감과 작업능률을 향상시킬수 있음과 아울러 별도의 예열기를 설치할 필요가 없어 설치비 및 운영비를 절감할수 있을뿐만 아니라 구조가 간단하여 연가로 제공할수 있으며 고장이 없이 장 기간 사용할수 있는 유용한 고안인 것이다.Therefore, according to the present invention, it is possible to reduce the fuel consumption and work efficiency by increasing the combustion efficiency without using a separate preheater to preheat the fuel, and to reduce the installation and operating costs by not having to install a separate preheater. Its simple structure makes it possible to provide it in year-end and is a useful design that can be used for a long time without failure.
