Problems solved by technology

The heating and drying drum can heat the aggregate and the recycled asphalt material at the same time. On the basis of not adding a second drying drum, the waste heat is used to effectively solve the problem of heating the recycled asphalt material, which greatly reduces the equipment cost and the use cost.

Abstract

The invention relates to the technical field of asphalt concrete processing equipment and provides a heating and drying roller, which comprises a roller, an under frame and a combustor. The roller comprises an inner barrel and an interlayer which is circularly arranged outside the inner barrel, and the outside of the interlayer is provided with a feed inlet and feed outlet. The two ends of the inner barrel are respectively provided with a feeding tank and a discharging tank which is communicated with the interlayer through a warm-air pipe. The inner barrel is used for heating aggregates, the interlayer is used for heating recovered asphalt materials ,one part of the heat required by heating the asphalt materials originates from the heat transfer of the wall of the inner barrel, and the other part originates from the hot air brought by separating materials from the inner barrel through the warm-air pipe, thus heating and drying the aggregates and meanwhile heating and drying the recovered asphalt materials.

Description

technical field [0001] The invention relates to the technical field of asphalt concrete processing equipment, in particular to a heating and drying drum, asphalt mixing equipment and recycled asphalt mixing equipment. Background technique [0002] The general design life of asphalt concrete pavement is 15 years, and the actual service life is usually only about 10 years, that is, every 10-15 years, asphalt concrete pavement needs to be renovated, so tens of millions of tons of asphalt concrete pavement waste will be generated every year . In order to regenerate these old asphalt mixtures, various regenerated asphalt mixing equipment are widely used to regenerate them. [0003] Existing recycled asphalt mixing equipment, one is double-layer drum continuous mixing equipment, the inner side of which is the aggregate drying area, and the interlayer is the mixing area. After the aggregate is heated and dried in the drying area, it directly enters the mixing area. Add asphalt, m...
