Efficient and energy-saving hot melting kettle special for road marking material
The invention discloses an efficient and energy-saving hot melting kettle special for highway marking materials. An atomization type fuel oil burner atomizes fuel oil and then ignites the atomized fuel oil, an annular inner plate gathers flame towards the middle to enable the flame to heat an inner bottom plate of an inner kettle body, high-temperature flue gas generated by combustion is exhaustedfrom an exhaust pipe through the annular flue to heat the inner kettle body, the screw pitch of a spiral plate is gradually reduced from top to bottom, the temperature of smoke is the highest when the smoke just enters a surrounding flue, the gradually-expanding surrounding flue prolongs the staying time of the smoke on the surface of the lower portion of the inner kettle body, heat conduction oil in the heat conduction oil heating device is heated by the high-temperature smoke, the temperature is still maintained after the interval time of fuel oil heating is long, and paint solidification is prevented.
本发明公开了一种高效节能的公路标线材料专用热熔釜，雾化式燃油燃烧器将燃油雾化后点燃，环装内板将火焰向中间聚集使火焰加热内釜体的内底板；燃烧产生的高温烟气经环形烟道从排气管排出，对内釜体进行加热；螺旋板的螺距从上至下逐渐减小，烟气在刚进入环绕烟道时温度最高，渐扩式的环绕烟道增加烟气在内釜体下部表面停留的时间，导热油加热装置中的导热油经过高温烟气的加热，在燃油加热间隔时间较长后仍然维持温度，防止涂料凝固。
