Asphalt concrete material conveying device and method for heating asphalt concrete material

Abstract

The invention discloses a bitumen concrete feeding device and a method for heating bitumen concrete. First directly feeding the high-temperature tail gas discharged by the internal-combustion engine of the construction device for building bitumen road into the inner space of said bitumen concrete feeding device, to contact the bitumen concrete, then heating the bitumen concrete feeding device and the bitumen concrete. The invention has simple structure, easy installment, simple operation and lower cost.

Description

technical field [0001] The invention mainly relates to the field of asphalt road construction, in particular to an asphalt concrete material conveying device and a heating method for asphalt concrete. Background technique [0002] At present, in the construction equipment such as paver, transfer vehicle and remixer used in the construction of asphalt roads, there are asphalt concrete material conveying devices for conveying asphalt concrete. This kind of construction equipment has the following problems in the construction process : [0003] 1. When the construction equipment starts a new working day, since the temperature of the equipment itself is close to the ambient temperature, the asphalt concrete material conveying system of the equipment first comes into contact with a temperature as high as 140-160°C. Asphalt concrete will inevitably cause heat to flow to the system The rapid transfer causes the temperature of the asphalt concrete at the forefront of the material c...

[0003] 1. When the construction equipment starts a new working day, since the temperature of the equipment itself is close to the ambient temperature, the asphalt concrete material conveying system of the equipment first comes into contact with a temperature as high as 140-160°C. Asphalt concrete will inevitably cause heat to flow to the system The rapid transfer causes the temperature of the asphalt concrete at the forefront of the material conveying system to drop sharply below the allowable paving temperature, resulting in poor paving quality;

[0004] 2. During the construction process, the heat of asphalt concrete will be lost to the environment through the material delivery system

The heating methods of this kind of heating device mostly adopt infrared heating, direct heating of gas burner, hot air heating or microwave heating. completely solve the problem
