An energy-saving and environment-friendly old asphalt mixture feeding device for road use

Abstract

The invention discloses an energy-saving and environment-friendly road old asphalt mixture feeding device which is characterized by comprising a conveying device, a feeding pipeline, a hopper and a feed pipeline. The feeding device disclosed by the invention is simple in structure and reasonable in design, a conveying pipeline arranged outside the conveyor can be used for preventing the possible personal injury caused by the dropping of old asphalt mixture can be avoided when the old asphalt mixture is conveyed by a conveyor, the safety of staff is maintained, the old asphalt mixture subjected to grinding and screening treatment is shunt by virtue of six feed pipelines, a multi-pipeline multi-station process method is adopted, and the process flow is reasonably distributed, so that waiting time at a subsequent station is avoided, the difficulty of subsequent operations such as spraying, filtering and cleaning is reduced, the energy consumption and treatment time are saved, the aims of low time consumption and high efficiency are achieved, the included angle between the feed pipeline and the vertical direction is 45 degrees, and the feeding process is smooth when the feed pipeline is used for feeding at the included angle of 45 degrees.

Description

technical field [0001] The invention relates to the technical field of pavement materials, in particular to an energy-saving and environment-friendly old asphalt mixture feeding device for roads. Background technique [0002] Recycling and reuse of old asphalt mixed materials produced by asphalt pavement maintenance, as the name implies, is to separate and regenerate old asphalt mixed materials, so that old asphalt mixed materials can be traced back to the source, restored to the original characteristics of asphalt and stone materials, and regenerated into various The new mixture required by the grading, and the existing process methods all have deficiencies and limitations, especially the time difference between each stroke in the process, resulting in a large waste of labor and low production efficiency during work. Contents of the invention [0003] In view of the above problems, the present invention proposes an energy-saving and environment-friendly old asphalt mixtur...
