Repeated bending type asphalt block treatment device

Abstract

The invention relates to the field of asphalt, in particular to a repeated bending type asphalt block treatment device. The technical problem of the invention is to provide a repeated bending type asphalt block treatment device. According to the technical implementation scheme, the repeated bending type asphalt block treatment device comprises a mounting connecting bottom plate, a machine tool plate, an operation control screen, a tool box, a bending separation system and the like; the lower portion of the machine tool plate is welded to the mounting connecting bottom plate. According to the device, the waste asphalt plate is repeatedly bent, the bending degree and range are gradually expanded, the adhered aged geotextile is forced to be gradually separated from the surface of the asphaltblock; meanwhile, asphalt particles adhered to the outer side surface of the geotextile are shifted and separated; and the asphalt can be quickly torn when the waste asphalt is pretreated by utilizingthe telescopic spring conical thorns, so that the effect of the treatment process of waste asphalt recovery is simplified.

Description

technical field [0001] The invention relates to the asphalt field, in particular to a repeatedly bending asphalt block processing device. Background technique [0002] Bitumen is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It mostly exists in the form of liquid or semi-solid petroleum. The surface is black and soluble in carbon disulfide, carbon tetrachloride. Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. Pitch can be mainly divided into three types: coal tar pitch, petroleum pitch and natural pitch. Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural bitumen is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries as well...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the old asphalt pavement regeneration technology that is widely used, flexible, simple and can guarantee the quality in asphalt regeneration, the old asphalt pavement is milled and recycled with a milling machine, and it is transported back to the mixing plant. Generally, it contains anti-filter fabrics such as geotextiles to prevent roadbed soil from squeezing into the cushion layer. Geotextiles generally have a relatively high degree of adhesion to asphalt blocks. Without treatment, there are almost no gaps, so it is difficult to peel them off from the surface of asphalt blocks. It is very troublesome, so many processing plants will not separate the geotextiles, resulting in the disadvantage of declining the quality of the recovered waste asphalt. The technical problem of the present invention is to provide a repeatedly bending asphalt block processing device
