본 고안은 입자상의 고체 연료인 무연탄이나 왕겨 톱밥 등을 이송 스크류에 의하여 연소기에 공급시킬 경우 연료 공급통내의 입자상의 고체 연료가 연료 공급통 내주에 응결되는 것을 방지하여 하강 공급이 원활이 이루어지게 한 온수 보일러의 고체 연료 공급 장치에 관한 것으로 종래에는 호퍼상의 고체 연료 공급통에 연료를 가득히 채워 놓고 스크류의 이송 양만큼 자연 하강하면서 공급되게 하였기 때문에 입자상의 고체 연료 자체가 함유하고 있는 수분에 의하여 공급통 주연에 응결되어 하강하지 않아 공급이 어려운 문제점이 있었다.The present invention prevents condensation of particulate solid fuel in the fuel supply cylinder to the inner circumference of the fuel supply cylinder when the anthracite coal or rice husk sawdust, which is a particulate solid fuel, is supplied to the combustor by a transfer screw, so that the descending supply is smoothly performed. The present invention relates to a solid fuel supply device of a hot water boiler. In the related art, a solid fuel supply container in a hopper is filled with fuel and supplied as it descends as much as a screw feed amount. There was a problem that supply was difficult because it did not descend due to condensation at the lead.

본 고안은 이와 같은 결점을 적게하기 위하여 이송 스크류의 회전시에 공급통 내에서 승강봉이 승강하면서 승강봉에 착설된 날개가 입자상의 고체 연료를 하강시킬 수 있게 한 것으로 첨부 도면에 의하여 상세히 설명하면 다음과 같다.In order to reduce such drawbacks, the present invention allows the wing rods mounted on the lifting rods to lower the particulate solid fuel while the lifting rods are raised and lowered in the supply cylinder during the rotation of the feed screw. Same as

입자상의 고체 연료 공급통(1)과 연관시킨 연료 이송관(2)내에 이송 스크류(3)를 장설하고 연료 이송관(2)의 말단에 나팔상의 연소통(4)을 연관시킨 통상의 것에 있어서 고체 연료 공급통(1)내에 방사상으로 수개의 날개(5)를 착설한 승강봉(6)을 장설하여 하부에 코일 스프링(7)을 권설하고 승강봉(6)의 하단부(6a)는 이송 스크류(3)의 일측에 형성한 단턱진 캠(8)(8a)이 접지되게 하여서 된 것이다.In the conventional thing in which the transfer screw 3 is installed in the fuel delivery pipe 2 associated with the particulate solid fuel supply container 1, and the flared combustion cylinder 4 is associated with the end of the fuel delivery pipe 2. In the solid fuel supply container 1, the elevating rods 6 radially mounted with several wings 5 are installed, the coil springs 7 are installed in the lower portion, and the lower end 6a of the elevating rods 6 is a feed screw. The stepped cams 8 and 8a formed on one side of (3) are grounded.

미설명 부호 9는 모우터, 9a는 감속기, 10은 송풍기, 11은 보일러 동체이다.Reference numeral 9 is a motor, 9a is a speed reducer, 10 is a blower, 11 is a boiler body.

이상과 같이 된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention made as described above are as follows.

고체 연료 공급통(1)내에 방사상으로 수개의 날개(5)를 착설한 승강봉(6)을 장설하여 하부에 코일 스프링(7)을 권설하고 승강봉(6)의 하단부(6a)에는 이송 스크류(3)의 일측에 형성한 단턱진 캠(8)(8a)이접지되게 하였기 때문에 모우터(9)와 벨트로 연결된 감속기(9a)에 의하여 이송 스크류(3)가 서서히 회전하게 되면 이송스크류(3)의 일측에 형성한 단턱진 캠(8a)에 의하여 승강봉(6)이 상승하고 승강봉(6)의 하부에 권설한 코일 스프링(7)에 의하여 승강봉(6)의 하단부(6a)가 캠(8)(8a)의 단턱부를 벗어 날때 하강시켜 주므로 승강봉(6)에 방사상으로 착설된 수개의 날개(5)가 입자상의 고체 연료를 위로 상승시키다가 순간적으로 하강시키게 되므로 입자상의 고체 연료가 공급통(1)의 주위에 응결됨이 없이 하강되므로 입자상의 고체 연료를 연료 이송관(2)에 공급이 원활이 이루어져서 이송스크류(3)에 의하여 연소통(4) 내로 연료 공급이 원활이 이루어지게 한 것이다.In the solid fuel supply container 1, elevating rods 6 radially mounted with several wings 5 are installed, coil coils 7 are provided at the lower portion thereof, and a transfer screw is provided at the lower end 6a of the elevating rods 6. Since the stepped cams (8) (8a) formed on one side of the (3) are grounded, the feed screw (3) is gradually rotated by the reducer (9a) connected by the motor (9) and the belt. The elevating rod 6 is lifted by the stepped cam 8a formed at one side of 3), and the lower end 6a of the elevating rod 6 by the coil spring 7 installed at the lower portion of the elevating rod 6. Is lowered when it is out of the step of the cams (8) (8a), so that several wings (5) radially mounted on the elevating rod (6) raise the particulate solid fuel upwards and then immediately descend. Since the fuel descends without condensation around the supply container 1, the solid fuel is smoothly supplied to the fuel delivery pipe 2. This is made to smoothly supply the fuel into the combustion cylinder (4) by the transfer screw (3).
