Asphalt regeneration device

Abstract

The invention provides an asphalt regeneration device, and relates to the field of pavement engineering machinery. According to the technical scheme, the device comprises an asphalt storage bin and a heating device arranged above the asphalt storage bin, and a stirring device is arranged in the asphalt storage bin; the heating device comprises a box body, and a magnetron group and a transformer group for supplying power to the magnetron group are arranged in the box body; a heating plate is arranged on the outer surface of the asphalt storage bin, and a heat preservation layer is arranged on the face, away from the asphalt storage bin, of the heating plate. According to the asphalt regeneration device provided by the invention, after being electrified, the asphalt regeneration device is boosted by the transformer bank, the microwaves emitted by the magnetron group are emitted to the asphalt storage cabin through the waveguide cavity, and the asphalt storage cabin prevents the microwaves emitted by the magnetron group from being diffused and propagated all around; a large amount of microwaves are absorbed by the asphalt in the asphalt storage cabin and are converted into heat energy, so that the asphalt in the asphalt storage cabin is heated, and the heating is to heat the whole interior of the asphalt irradiated by the microwaves.

Description

technical field [0001] The present disclosure relates to the technical field of road construction machinery, in particular to an asphalt recycling device. Background technique [0002] During the use of asphalt pavement, various diseases such as potholes, cracks, wrapping, pitting, etc. often occur. The asphalt pavement maintenance vehicle is a kind of maintenance equipment specially used to deal with the above diseases. Among them, the in-situ regenerative asphalt pavement maintenance vehicle is one of them. The existing on-site regenerative asphalt pavement maintenance vehicles have the following disadvantages: the in-situ regenerative heating wall mostly uses fuel / gas open flame heating, gas infrared heating or diesel hot air circulation heating, and the heating temperature of the asphalt pavement is not easy to control accurately, which is easy to cause asphalt pavement The aging and coking of the 1mm-5mm surface asphalt, the road performance of the pavement after regen...

Problems solved by technology

The existing on-site regenerative asphalt pavement maintenance vehicles have the following disadvantages: the in-situ regenerative heating wall mostly uses fuel / gas open flame heating, gas infrared heating or diesel hot air circulation heating, and the heating temperature of the asphalt pavement is not easy to control accurately, which is easy to cause asphalt pavement The aging and coking of the 1mm-5mm surface asphalt, the road performance of the pavement after regeneration will decline, and there will be a lot of toxic fumes during the construction process, which will cause serious environmental pollution problems; and there will be safety hazards such as liquefied gas leakage and bursting; the market The overturning mechanism of the upper heating wall is mostly completed by hydraulic cylinders, and the overturning angle is ≤90°. There is a problem that the ramp cannot be constructed, and the adaptability to working conditions is poor.
