一种沥青混凝土搅拌设备油燃烧器高压式喷嘴
一种沥青混凝土搅拌设备油燃烧器高压式喷嘴属工程机械领域。
技术介绍
沥青混凝土搅拌设备是将符合规定级配的混合料加热后,与适当比例的热沥青和矿粉一起,在规定温度下经均匀搅拌得到热态沥青混凝土的专用机械设备。油燃烧器是该设备加热装置的主要部件,喷嘴则是油燃烧器的核心部件。目前,油燃烧器喷嘴主要有机械式和低压式两种。机械式喷嘴,又叫离心式喷嘴,它又分为简单机械雾化喷嘴,和回油式机械雾化喷嘴两种;简单机械雾化喷嘴的调节范围有限,雾化质量差,而且部件高速旋转,制造和运行都较复杂,最大负荷调节比为1∶2;回油式机械雾化喷嘴的缺点是大量热回油使工作温度升高,耗电量大,结构较复杂,调节范围也小。低压式喷嘴是燃油以低压经喷嘴喷出,同时低压空气从喷嘴油孔周围缝隙中喷出与燃油进行雾化并作为燃油的助燃剂,喷嘴形式又可分为直流式、涡流式和比例式三种,缺点是生产能力调节范围窄,雾化油粒较粗,雾化角较大,而且容易堵塞、维修不便。亟待攻克技术难关,创新研制一种适用于沥青混凝土搅拌设备油燃烧器的新型喷嘴,以满足公路、铁路、机场、广场等沥青混凝土施工的迫切需 ...
