Forced intermittent special mixing apparatus for asphalt mixture regeneration

Abstract

The invention discloses a brand-new forced intermittent special mixing apparatus for asphalt mixture regeneration. Aiming at the problems and defects of conventional regeneration apparatus matching solutions, main parts of a mixing apparatus are optimized and designed again; and a brand-new integrated apparatus matching solution specialized for production of regenerated asphalt mixture is provided. A regeneration function and a conventional mixing plant are optimized and integrated; the arrangement manner and position of a mixing pot are redesigned, so that reclaimed materials can be directly added from the above of the mixing pot; a conveying material path of the reclaimed materials is simplified; the problem of cementation of the reclaimed materials can be effectively alleviated; and the volume and mixing capacity of the mixing pot are increased, thereby guaranteeing that output of the apparatus is not influenced during the production of large-scale regenerated asphalt mixture. By adopting the whole integrated design, the structure is more compact; the whole height of the apparatus is effectively reduced; installation debug and daily operation and daily maintenance are facilitated; and energy consumption of the apparatus is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of asphalt mixture mixing equipment, and in particular relates to a special mixing equipment for forced intermittent asphalt mixture regeneration. Background technique [0002] Since the speed and scale of highway construction in China ranks first in the world, with the continuous increase of highway mileage, highway construction will gradually transition from the current [construction-based] to [construction and maintenance] and the future [cultivation-based] ] to a new stage of development. The asphalt pavement that has been built in the early stage has gradually entered the period of repair, maintenance, and renovation, and the amount of recycled asphalt pavement materials produced thereby is increasing and increasing year by year. Due to the limitations of recycling technology and equipment for asphalt pavement materials in China, the reasonable utilization rate of recycled asphalt pavement materials in...

AI Technical Summary

Problems solved by technology

Due to the limitation of recycled asphalt pavement material regeneration technology and equipment in my country, the reasonable utilization rate of recycled asphalt pavement material in China is still less than 20%.

[0014] ●Due to the limitations of the design of the conventional mixing itself, the volume of the mixing pot is only configured according to the needs of the production of conventional asphalt mixture. When producing recycled asphalt mixture, the overall constant of the equipment will be reduced due to the need to prolong the mixing time;

[0015] ●In addition, the layout of the current recycling equipment, because the recycled material (RAP) can only be added from the side of the mixing pot, it is not suitable to stir and mix evenly, and it will also increase the mixing time to a certain extent, resulting in a decrease in the output of the equipment
