Embodiment Construction

[0016] Such as figure 1 As shown, the present invention includes a new aggregate drying heating zone 4 and a recycled material drying heating zone 5 .

[0017] The new aggregate drying heating area 4 is composed of the new aggregate inlet 7, the drum 1, the new aggregate outlet 8, the hollow material guide cone 11, and the turning blade 6. There is a burner 2 on the end surface of the drum 1; to realize the new The aggregate is dried and heated to a certain high temperature.

[0018] Recycled material drying heating area 5 is composed of hollow material retaining cone 12, recycled material outlet 10, turning blade 6, and recycled material inlet 9, which realizes drying moisture of recycled material and heating to a certain high temperature.

[0019] The smoke box 3 is the smoke collection and exhaust passage of the drying heating drum.

[0020] New aggregates and recycled aggregates after drying and heating have their own outlets and cannot be mixed.

[0021] The drum 1 is ...

Abstract

The invention relates to a roller capable of simultaneously drying and heating a reclaimed material and new aggregate, which belongs to the technical field of manufacturing of hot mix plant recycling equipment for a mixture. The roller capable of simultaneously drying and heating the reclaimed material and the new aggregate comprises a roller (1). The end face of one end of the roller (1) is provided with a combustor (2), and the tip of the other end of the roller (1) is provided with a smoke box (3); two drying and heating areas are sequentially arranged in the section of the roller (1) located between the combustor (2) and the smoke box (3), and material reversing blades (6) are covered on the inner walls of the drying and heating areas; the roller (1) is provided with a new aggregate inlet (7), a new aggregate outlet (8), a reclaimed material inlet (9) and a reclaimed material outlet (10); and a material guiding cone (11) and a material blocking cone (12) are arranged on a boundary cross section of the two drying and heating areas. According to the invention, one roller is used for simultaneous drying and heating of the reclaimed material and the new aggregate to replace heating and drying through two rollers, so ageing of asphalt in the reclaimed material is prevented, process is simplified, and manufacturing cost for equipment is reduced.

Description

technical field [0001] The invention relates to a drum for simultaneously drying and heating reclaimed materials and new aggregates, and belongs to the technical field of plant-mixed heat-recycled mixed material equipment manufacturing. Background technique [0002] After being used for a certain period of time, asphalt pavement will have diseases and reduce road performance, thereby affecting the driving of vehicles. Therefore, asphalt pavement needs frequent maintenance and repairs. In the process of maintenance and repair, a large amount of waste materials will be produced after excavation of the pavement. These waste materials still have high utilization value as asphalt pavement materials. If they are discarded, it will cause a great waste of material resources and cause pollution to the ecological environment. [0003] The research shows that the plant-mixed hot recycling technology is the most widely used and mature recycling technology, which has good adaptability an...
