Description

Extrusion type asphalt pavement milling, planing, crushing and screening device
Technical Field
The invention relates to the technical field of asphalt processing, in particular to an extrusion type asphalt pavement milling material crushing and screening device.
Background
The asphalt pavement regenerating technology is a complete set of technological process for making a regenerated asphalt mixture with a certain pavement performance by digging, recovering, crushing and screening old asphalt pavement to be renovated or discarded, properly matching with new aggregate and new asphalt material, and remixing the mixture to form a regenerated asphalt mixture with a certain pavement performance, which is used for paving a pavement surface layer or a base course. The plant mixing hot recycling method is a construction method for milling and digging an old asphalt pavement, transporting the old asphalt pavement back to a mixing plant, then intensively crushing the old asphalt pavement, carrying out proportioning design according to quality requirements of different levels of the pavement, determining the proportion of materials such as an old asphalt mixture, a regenerant, a new asphalt material, a new aggregate and the like, and then stirring the materials in a mixer to form a new mixture for paving the asphalt pavement. The method is suitable for cold milling and hot spreading construction process of road surface, and may be used in repairing the upper, middle and lower layers of asphalt road surface and reinforcing base course and road bed.
The old asphalt mixture (RAP) is fragments obtained by milling and crushing old road surfaces, wherein most of the fragments are a combination of a plurality of original road surface mineral aggregates and old asphalt which are bonded into a mass and are not single aggregates. The differences of old asphalt mixtures from different sources are also large, and the agglomeration conditions of the old asphalt mixtures are greatly different due to the influence of a plurality of factors such as different gradation, different milling thicknesses, different milling machines and the like.
Thus, the pre-treatment of asphalt road milling stock (RAP) is a very important procedure, mainly for the treatment of large "lumps" in the sample, because when the oversized, caked old mix is heated, a lot of energy is wasted due to the poor thermal conductivity of the asphalt. Furthermore, the variability of the aggregate grading, the oilstone ratio and other material performances of the RAP is a technical bottleneck for restricting the high blending and high-level application of the hot recycled asphalt mixture. Therefore, pretreatment processes such as crushing, screening, grading and stacking of the asphalt pavement milling material (RAP) are particularly necessary.
At present, in actual work, crushing methods include manual crushing, mechanical crushing, thermal decomposition and the like. The particular method employed will depend upon the particular circumstances. For large-scale hot recycling mixed material mixing plants, mechanical crushing is often adopted, and meanwhile, a certain requirement is also provided for a crusher, so that old asphalt materials cannot be crushed too finely, and the production rate of the crusher is required to be matched with the production rate parameter of a mixer. In actual engineering, due to the lack of RAP pretreatment equipment and technology, the pretreatment of milling materials is at a simple and extensive technical level, which has an extremely adverse effect on the development of the asphalt mixture regeneration technology of highway engineering in China. In the prior art, the manual crushing method is backward, the time is long, the particle size of the crushed old pavement material is not uniform, and the crushing quality is difficult to guarantee.
Therefore, the inventor provides an extrusion type asphalt pavement milling, planing, crushing and screening device with study and improvement on the existing structure and deficiency in view of the experience of abundant design development and actual manufacturing of related industries for many years, so as to achieve the purpose of higher practical value.
