A repeatedly bending asphalt block processing device

Abstract

The invention relates to the asphalt field, in particular to a repeatedly bending asphalt block processing device. The technical problem of the present invention is to provide a repeatedly bending asphalt block processing device. The technical embodiment of the present invention is: a repeatedly bending asphalt block processing device, including an installation and connection base plate, a machine tool board, an operation control panel, a tool box, and a bending and separation system; the bottom of the machine tool plate is welded to the installation and connection base plate . The invention realizes repeated bending of waste asphalt slabs and gradually expands the bending degree and range, forcing the adhered aging geotextile to gradually detach from the surface of the asphalt block, and at the same time moves the asphalt particles adhered to the outer surface of the geotextile Separation, and can use the telescopic spring awl to quickly tear the asphalt when pretreating the waste asphalt, which simplifies the effect of the treatment process of waste asphalt recycling.

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...

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
