Description

Mixing and discharge apparatus of wasted ascone connected to the cylindrical rotating drum discharge unit {mix and discharge apparatus of wasted-ascon connecting way out of cylindrical drum}

The present invention relates to a device for mixing and discharging waste ascon which is connected to a cylindrical rotating drum discharge unit.

Asphalt concrete is a combination of asphalt and cement, which is the preferred material for the construction of roads, but these asphalt concretes cannot be used permanently and must be replaced after a certain period of time. As a result, the treatment of waste asphalt concrete, which is produced in large quantities, is a social problem. Therefore, there is a growing interest in recycling such waste asphalt concrete (hereinafter referred to as 'waste asphalt)'.

In particular, asphalt used in asphalt concrete is mainly composed of asphaltenes, saturated hydrocarbon oils, naphthenic aromatic oils, and polar aromatic oils.It is a kind of final residue when classifying crude oil. Waste ascon is classified as industrial waste causing pollution due to the polluted groundwater, rivers, and rivers causing serious pollution problems.

Therefore, research is being conducted to prevent or minimize the pollution caused by waste ascon, and most of the technologies applied in the field as the recycling technology of waste ascon are hot mix. Hot-In-Place Recycling, where waste asphalt concrete is recovered by direct heating at the repackaging site, and the waste asphalt concrete, new asphalt concrete, and rejuvenator are properly mixed and repacked directly on site. Heat-plant recycling (Hot-In-), which recovers asphalt concrete plant and waste asphalt concrete to asphalt asphalt plant, and then re-mills and separates it, and then mixes it with plant powder and recycled additives in a plant mixer. Plant Recyclimg) is proposed.

The present invention relates to a recycled ascon attachment provided by the waste ascon regenerator to supply and recycle new zeal asphalt or and / or a regeneration additive which is added to recover the insufficient properties of the recycled waste ascone processed inside the cylindrical rotating drum. .

Research on the regeneration additive used in the above method has also been actively conducted, for example, US Patent No. 4,373,961 using a special emulsified asphalt to break down the old waste ascon finely to mix and reuse at room temperature While presenting the method, re-packaging method using emulsified asphalt using water and emulsifiers as regeneration additives. For the packaging at room temperature, waste asphalt is collected and specially formulated emulsified asphalt is mixed in a crushed state by crusher at room temperature. The method is used.

In addition, U.S. Patent No. 3,793,189 describes a mixture of deasphaltde oil, heavy distillate, and residual oil with propane as a supercritical fluid separation method to improve the properties of aged asphalt. US Patent No. 3,221,615 discloses a method of restoring the properties of aged asphalt using coal tar derivatives, but the additive for regeneration used here is extracted from coal tar and aromatic benzene rings. Is a compound having a functional group of an alkyl compound having 2 to 4 and phenolic and hydroxy derivatives.

In addition, US Patent No. 4,278,469 discloses a composition of a mixture of some oil extracted from asphalt, a specific polymer and a heavy aromatic solvent as a regeneration additive for road repair and surface treatment, and US Patent No. 4,325,738 describes shell oil (shale oil). In the present invention, an additive for improving the aging of asphalt by adding acid salts to a pyridine-based mixture extracted from Pyridine-based mixtures is disclosed. Also, US Pat. No. 4,549,834 discloses asphalt oil and resin. And an additive for waste ascon regeneration composed of pitch.
