DRIER OF ASPHALT PLANT
PROBLEM TO BE SOLVED: To provide a drier of an asphalt plant capable of restraining reduction in the raking-up function and the feed function, by preventing sticking-growth of an aggregate to a blade surface, by heating even a raking-up blade and a check blade in the vicinity of a drum rear end part, while preventing dew condensation on and after an exhaust duct by adjusting the exhaust gas temperature.SOLUTION: A hot blast lead-out duct 17 having a hot blast quantity adjusting air quantity adjusting damper 15 in the middle, is connected to a hot hopper 6 of a drum 4-front end part, and the other end opening part of this hot blast lead-out duct 17 is faced to a drum 4-rear end part, and a part of a high temperature hot blast led-out from a burner 7 is supplied to the vicinity of the drum 4-rear end part via the hot blast lead-out duct 17.SELECTED DRAWING: Figure 1
【課題】 排ガス温度を調整して排気ダクト以降での結露防止を図りつつ、ドラム後端部付近の掻き上げ羽根や逆止羽根をも加熱可能として羽根表面への骨材の付着・成長を防止して掻き上げ機能や送り機能の低下を抑制可能としたアスファルトプラントのドライヤを提供する。【解決手段】 ドラム４前端部のホットホッパ６に、途中に熱風量調整用の風量調整ダンパー１５を備えた熱風導出ダクト１７を連結し、この熱風導出ダクト１７の他端開口部をドラム４後端部に臨ませ、バーナ７から導出される高温の熱風の一部を前記熱風導出ダクト１７を介してドラム４後端部付近に供給させる。【選択図】 図１
