Abstract
본 고안은 석탄 보일러 또는 폐기물 소가로에서 배출되는 고열의 소각 잔유물(ASH)을 보일러 또는 소각로 하부로부터 받아서 다음 처리공정으로 이송시키기 위하여 설치되는 재이송용 스크류콘베이어에 대한 것으로 종래 스크류콘베이어에 투입되는 고온의 재 등을 냉각시키기 위하여 스크류콘베이어 케이스에 쟈켓을 설치하고 이 쟈켓 내부로 냉각수를 유수시켜 콘베이어를 냉각시켰으나 재 등의 소각잔유물의 고온을 냉각시키기에는 미흡하였던 바 본 고안은 콘베이어 외부를 냉각시킬뿐 아니라 콘베이어 내부의 스크류 축을 중공으로 하여 이 중공축에 지속적으로 냉각수를 공급하여 콘베이어 내, 외부를 동시 냉각하게 하므로서 콘베이어의 수명연장은 물론 잔유물 이송이 보다 정확하게 이루어질 수 있도록 한 고안에 대한 것이다.The present invention relates to a screw conveyor for re-conveying which is installed to receive a high-temperature incineration residue (ASH) discharged from a coal boiler or waste incinerator from a boiler or an incinerator bottom to a next treatment process. In order to cool the ash, a jacket was installed on the screw conveyor case and the coolant was flowed into the jacket to cool the conveyor. However, it was not enough to cool the high temperature of incineration residues such as ash. The screw shaft inside the conveyor is hollowed out to continuously supply cooling water to the hollow shaft to simultaneously cool the inside and the outside of the conveyor, thereby extending the life of the conveyor as well as designing the residue to be made more accurately.

상기와 같이 구성된 본 고안의 동작상태를 설명하면 모터의 회전력이 체인에 의하여 체인스프라켓(14)을 회전시키고 스프라켓(14)은 회전축(13)을 회전시키며 이 회전축(13)은 중공축(10)을 회전시키며 중공축(10)의 좌우선단은 베어링(18)(18a)에 의하여 지지된 상태에서 회전하면서 재투입구(7)로부터 장입되는 고온의 재 등의 잔유물을 중공축(10) 외주면에 권회입설된 스크류(11)에 의하여 이송시키게 된다. 이때 중공축(10) 일측선단에 연설된 로타리 죠인트(22)의 입수구(5a)로부터 냉각수가 입수되어 중공축(10) 내주면에 장설된 냉각수 역류 파이프(12) 이주면과 중공축(10) 내주면의 공간부를 따라 유수되면서 중공축(10)을 냉각시키게 되고 냉각된 냉각수는 냉각수 역류 파이프(12)에 천설된 통공(15a)을 통과하여 냉각수 역류 파이프(12) 내주면을 따라 냉각수 출수 파이프(23)을 통하여 결국 로타리 죠인트(22)의 출수구(6a)로 배출되게 되어 가장 고열을 직접 받는 중공축(10)을 지속적으로 냉각시키게 되고 이와는 별도로 콘베이어 케이스(2) 외주면에 권포된 유수쟈켓(3)에 냉각수가 냉각수 입수구(5)와 출수구(6)를 통과하면서 쟈켓(3) 내부에 자그자그로 설치된 다수개의 파이프로 된 이격간(4) 사이를 지나면서 냉각수가 와류되어 콘베이어케이스(2)의 고열을 냉각시키므로서 콘베이어 내외부를 동시에 냉각시키게 된다. 그런데 중공축(10) 외주면에 권회된 스크류(11)가 고온의 재 등이 투입되는 투입구(7)측에는 피치가 비교적 조밀하게 되어 있어 최초에 투입되는 재 등의 고온을 냉각시키면서 재 등의 이송속도를 지연시키므로서 냉각시간을 비교적 길게하고 피치거리가 비교적 큰 스크류(11a)를 통과할 때는 빠르게 이송되게 하므로서 냉각능률을 올리면서 효율적인 냉각작업을 할 수 있도록 한 고안이다.Referring to the operating state of the present invention configured as described above, the rotational force of the motor rotates the chain sprocket 14 by the chain, the sprocket 14 rotates the rotary shaft 13, the rotary shaft 13 is a hollow shaft 10 The left and right ends of the hollow shaft 10 are rotated in a state supported by the bearings 18 and 18a, and the residues such as the hot ash charged from the re-entry 7 are wound on the outer peripheral surface of the hollow shaft 10. It is transferred by the installed screw (11). At this time, the coolant is obtained from the inlet port 5a of the rotary joint 22 on the one end of the hollow shaft 10 and the migration surface of the coolant backflow pipe 12 installed on the inner circumferential surface of the hollow shaft 10 and the inner circumferential surface of the hollow shaft 10. The hollow shaft 10 is cooled while flowing along the space of the cooling water, and the cooled coolant passes through the through hole 15a installed in the coolant backflow pipe 12, and the coolant output pipe 23 along the inner circumferential surface of the coolant backflow pipe 12. Eventually it is discharged to the outlet 6a of the rotary joint 22 to continuously cool the hollow shaft 10 that receives the highest heat directly, and separately to the flowing jacket 3 wound on the outer circumferential surface of the conveyor case 2. As the coolant passes through the coolant inlet (5) and the outlet (6), the coolant is vortexed as it passes between the spaces (4) of a plurality of pipes installed in the inside of the jacket (3). During cooling Since standing thereby the conveyor at the same time internal and external cooling. However, the pitch of the screw 11 wound on the outer circumferential surface of the hollow shaft 10 has a relatively dense pitch at the inlet 7 side where the ashes of high temperature are introduced, while cooling the high temperature of the ashes, which are initially introduced, and conveying the ashes. By delaying the cooling time is relatively long, and when passing through the screw (11a) having a relatively large pitch distance, it is designed to enable efficient cooling work while increasing the cooling efficiency.
