Description

Apparatus for manufacturing of recycled mixture by using a waste asphalt pavement}

The present invention relates to an apparatus for producing a recycled mixture using waste ascon, and more specifically, to dig and grind waste ascon using indirect heat, and to prepare a new asphalt mixture by mixing new aggregates and additives with the waste ascon. The present invention relates to an apparatus for producing a recycled mixture using waste ascon.

Maintaining and repairing the road system is not only costly and time consuming, but also has difficulty in obtaining materials of appropriate quality in some regions. As an alternative to this problem, a method for recycling used ascon has been proposed to recycle the used ascon by removing the asphalt pavement which is at the end of its life or requires re-packaging.

Here, looking at the advantages of recycling the waste ascon, first, if the waste material generated by the packaging waste material or surface cutting, etc., which are removed by expansion packaging is used for packaging again, the expensive cost of disposing of the waste ascon is reduced. At the same time, it is possible to obtain economic effects, such as reducing the cost of purchasing new materials, and to prevent the environmental pollution due to the saving of resources and energy, and the landfill and dumping of waste materials.

And, from an engineering point of view, it is possible to greatly improve the structural performance without changing the layer thickness of the paved roads, no need for alternative road facilities during construction, frostbite fragility can be reduced, and surface and substrate disturbance problems. There are advantages such as that can be fixed.

As an example of a method of recycling such waste ascon, in the prior art, there is a method of recycling waste ascon by adding waste ascon to an incinerator and applying high temperature heat.

However, the prior art is as follows: ① cylindrical gear burner dryer type, ② is exposed to the outside, ③ can be used only in a specific area due to the high noise, ④ burner flame RAP (Reclaimed Asphalt Pavement; recovery asphalt It is difficult to control the proper temperature because it is directly heated to pavement), and the new aggregate and waste aggregate are heated at the same time in one drum, so the moisture content of the aggregate is high, making it difficult to control the temperature. ⑤ It is difficult to move when it is mobile due to complicated equipment, and it requires many additional equipment such as wet dust collector, dry dust collector, heating burner, and duct installation. ⑥ The direct heating method burns the asphalt and binders contained in the waste ascon. Therefore, when regenerated asphalt is mixed with new aggregates, new asphalt and new binders have to be added in large quantities, resulting in more cost. ⑦ When using diesel or bunker C oil as fuel, the second environmental pollution problem is caused by combustion gas emission. It can cause a high risk of fire, it is difficult to install and install when using LPG, ⑧ It is impossible to mass-produce recycled asphalt in case of mobile type, and heat the aggregate directly, As it melts, the aggregate aggregate surface is continuously heated by heat, causing the asphalt and binders to be burned. Should result in excessive consumption of fuel, and Due to its weakness, burners are often replaced and cylindrical drums are replaced. In the case of flat grinding waste ascon (surface layer), problems such as over-melting or asphalt and binder are almost oxidized by direct heating flames make it impossible to regenerate. Had.

The present invention has been made to solve the problems of the prior art, the waste ascon is recycled by indirect heat treatment to improve the quality, noise reduction and disposal costs are reduced by using an electric furnace that does not require incinerators and dust collector facilities, It is an object of the present invention to provide a recycled mixture production apparatus using waste ascon which can be directly disposed and processed as much asbestos in the field as necessary, thereby eliminating transportation costs and providing excellent field mobility.
