Description
본 고안은 소결원료의 생석회첨가장치에 관한 것으로 특히 고로의 주원료인 소결원료 배합공정에서 조립(造粒)향상제로 첨가디는 생석회를 벨트콘베어를 통하지 않고 드럼형혼합기에 에어분사식으로 첨가하는 소결원료의 생석회첨가장치에 관한 것이다.The present invention relates to an apparatus for adding quicklime to sintered raw materials. In particular, sintered raw materials which are added to the drum type mixer by air injection without the use of quicklime added as a granulating enhancer in the sintering raw material blending process, which is the main raw material of the blast furnace. It relates to a quicklime adding device.
종래의 소결원료 배합공정은 도1에 도시한 바와같이 철광빈석(15)의 각종 분철광석과, 부원료 및 연료빈(16)의 석회석, 사문암, 분코크가 정량절출장치(25)를 통해 일정비율로 벨트콘베어(3)에 적치되어 이송된다.In the conventional sintering raw material mixing process, as shown in FIG. 1, various iron ores of the iron ore ore 15, and limestone, serpentine and powdered coke of the fuel and the fuel bin 16 are fixed at a predetermined ratio through the quantitative cutting device 25. The lower belt conveyor (3) is placed and transported.
그리고 최종적으로 배합원료의 조립향상제(Binder)인 미분의 생석회가 생석회빈(1)으로부터 정량절출장치(25)를 통해 벨트콘베어(3)의 부원료 및 연료 상부로 절출되면서 드럼형혼합기(4)에 장입된다.Finally, the quicklime of the fine powder, which is a binder of the blending raw material, is cut out from the quicklime bin 1 through the quantitative cutting device 25 to the upper part of the belt conveyor 3 and to the upper part of the fuel and to the drum type mixer 4. It is charged.

Spray at high pressure.
또한 생석회이송관(7)을 따라 나란히 설치되는 에어공급관(8)은 좌측단에 솔레노이드밸브(8-1)가 설치되어면서 우측단이 폐쇄되어 있고, 그 외주면에 각각 보조밸브(10)에 의해 개폐되는 다수의 고무호스(26)가 결합되어 있다.In addition, the air supply pipe 8 installed side by side along the quicklime feed pipe 7 is closed at the right end while the solenoid valve 8-1 is installed at the left end, and is opened and closed by an auxiliary valve 10 on its outer peripheral surface. A plurality of rubber hoses 26 are combined.
여기서 다수의 고무호스(26)는 각각 보조승합기(9)에 연결되어 에어공급관(8)의 에어를 보조승합기에 공급하게 된다.Here, the plurality of rubber hoses 26 are connected to the auxiliary multipliers 9 to supply air of the air supply pipe 8 to the auxiliary multipliers.
이하 본 고안의 작용을 설명한다.Hereinafter will be described the operation of the present invention.
스크루피더(12)로부터 적정량으로 절출되는 생석회는 생석회이송관(7)으로 유입되고, 솔레노이드밸브(11)가 개방되면서 에어공급관(11-1)으로부터 고압의 에어가 생석회이송관(7)에 공급되면 생석회이송관(7)의 생석회는 압송된다.The quicklime cut out in a proper amount from the screw feeder 12 flows into the quicklime transfer pipe 7, and when the solenoid valve 11 is opened, high-pressure air is supplied from the air supply pipe 11-1 to the quicklime transfer pipe 7. The quicklime in the pipe 7 is pressurized.
이때 솔레노이드밸브(8-1)와 보조밸브(10)가 개방되면서 보조승압기(9)로부터 분사되는 고압의 에어는 생석회이송관(7)의 생석회 압송을 도와주게 된다.At this time, the high-pressure air injected from the auxiliary booster 9 while the solenoid valve 8-1 and the auxiliary valve 10 are opened helps the quicklime transfer of the quicklime transfer pipe 7.
