Abstract

The invention discloses an efficient asphalt mixing furnace, comprising a barrel assembly, a circular retaining plate, a base, an igniter assembly, a coal powder grinder, a coal powder delivery pipe and at least four roller assemblies; the igniter assembly includes an igniter cylinder, an igniter base, an igniting device and an air supply system; one end of a barrel body opposite to the igniter cylinder is provided with the circular retaining plate; the igniting device is disposed at the right end of the igniter cylinder; the air supply system includes an air supply pipe and a fan; the igniter cylinder is formed by nesting an outer tube and an inner tube and forms an interlayer cavity; a refractory brick heat-insulating layer is adhered to the inner wall of the inner tube; the efficient asphalt mixing furnace is further characterized in that the circular retaining plate is a conical circular plate having the outer circular edge facing inward and extending out along the center axis of the barrel body; an air passage in the igniting device is communicated with inner holes of the cylinder refractory brick heat-insulating layer by through holes between the outer tube and inner tube interlayer cavity of the cylinder and the cylinder refractory brick heat-insulating layer. The efficient asphalt mixing furnace is high in combustion efficiency and significantly energy-efficient.

Description

technical field [0001] The invention relates to an asphalt mixing device, in particular to an asphalt mixing furnace. Background technique [0002] Asphalt mixing furnace is a common machine for producing asphalt concrete. Part of the asphalt mixing furnace is heated by pulverized coal igniter. The existing asphalt mixing furnace generally includes a barrel assembly, an annular baffle, a base, an igniter assembly, a pulverized coal grinder, a pulverized coal conveying pipeline, and at least four sets of roller assemblies. The refractory brick insulation layer is arranged inside the igniter drum. When in use, coal powder burns in the inner hole of the drum refractory brick insulation layer. Although the refractory brick heat insulation layer is set, a large amount of heat is directly transferred to the drum wall by the refractory brick heat insulation layer and dissipated, resulting in large energy loss. Contents of the invention [0003] Aiming at the deficiencies of th...
