Road milling asphalt waste recycling device

Abstract

The invention relates to a road milling asphalt waste recycling device. The device comprises a crusher and a stirring mechanism, a walking mechanism is further included, the crusher and the stirring mechanism are fixedly connected to the walking mechanism; the stirring mechanism comprises a stirring part and a feeding part; the stirring part comprises a stirring box, a stirring barrel and a partition plate; the stirring box is provided with a discharging end and a feeding end, and the feeding end of the stirring box communicates with the crusher. First valves are arranged at the discharging end and the feeding end of the stirring box; the discharging end of the feeding part is communicated with the stirring box; the partition plate is of an annular structure, the outer ring edge of the partition plate is fixedly connected to the inner wall of the stirring box; the inner ring edge of the partition plate is fixedly connected to the edge of an upper opening of the stirring barrel, a second valve for opening and closing the stirring barrel is arranged in the edge of the upper opening of the stirring barrel, the discharging end of the stirring barrel communicates with the discharging end of the stirring box, a heating piece is arranged around the stirring barrel, and stirring blades are arranged in the stirring barrel. The regeneration quality of the asphalt mixture can be improvedwhile the production site is changed along with the construction site.

Description

technical field [0001] The invention relates to the technical field of construction waste recovery devices, in particular to a recovery and reuse device for road milling asphalt waste. Background technique [0002] At present, the waste asphalt mixture after laying the road surface and the asphalt mixture for old road renovation are processed as follows: 1. Discard directly, resulting in increased production costs and polluting the environment; 2. Cold recycling, directly adding waste asphalt mixture to New liquid asphalt and other materials are used for road paving during regeneration. The quality of the recycled mixture is not high and the durability is poor; 3. Heat recovery, the waste asphalt mixture is collected and crushed, but the overall recovery rate is not high, which will cause waste of resources and polluted environment. [0003] In the prior art, the publication number is CN104233917A, which discloses a method for reusing waste asphalt mixture, the technical po...

AI Technical Summary

Problems solved by technology

[0004] The existing technical solution above has the following defects: it can be concluded from the description of the technical solution and the accompanying drawings that the technical solution still uses heat treatment of the asphalt mixture to reuse the asphalt mixture, but the technical solution is in the During the heating process, the air will be in contact with the asphalt mixture, which will cause the asphalt to produce a chemical reaction, which will affect the quality of the recycled asphalt mixture. At the same time, it is still inconvenient to follow the construction site for transshipment, which will make the quality of the produced asphalt mixture relatively poor. Good and the transportation cost will be relatively high
