Abstract
The invention relates to an improved mounting structure of a flue baffle of a heating furnace. The improved mounting structure comprises a rotating shaft and the baffle arranged on the rotating shaft. The baffle is arranged in a flue. The rotating shaft comprises a driving shaft and a driven shaft. The driving shaft is provided with an extending input shaft, and the extending input shaft is fixedly connected with a transmission structure connecting plate and a driving rotary handle. The driving rotary handle is hinged to a connecting piece, the connecting piece is hinged to a driven rotary handle, and the other end of the driven rotary handle is fixedly connected with the driven shaft. The parts, outside the driving shaft and the driven shaft, of the flue are provided with fixed sleeves. Flanges are arranged on the fixed sleeves, and end covers are arranged at the two ends of the fixed sleeves. The flanges are fixedly connected with external fixed pieces of the end covers. Rotation of a plurality of rotating shafts is operated at the same time through the connecting piece, and therefore a plurality of rows of baffles are opened and closed. Meanwhile, gaps are arranged between the left end covers and the right end covers, smoke passes through the interior of the flue to generate negative pressure, air enters the flue from the gaps, no smoke dust is left between the fixed sleeves and the rotating shaft, the situation that smoke dust deposits in the gaps of the rotating shaft, and consequently the rotating shaft is stuck is avoided, and smoke cannot overflow.
