Description

Recycling apparatus using waste asphalt, waste concrete and filler

The present invention can be reused by mixing the components of the semi-rigid mixture consisting of waste asphalt, cement, fillers, emulsifiers crushed to less than 40mm at the optimum blending composition ratio and recycling of environmental problems due to waste and resources The present invention relates to a recycling device using waste asphalt and waste concrete and fillers capable of pursuing raw material supply and economic profits.

Roads are one of the important social overhead capitals that must be steadily established or continuously repaired. These roads are rapidly deteriorated due to the rapid increase in weight and weight of the vehicle, and a lot of waste asphalt is generated as the road is continuously constructed and repaired for high speed and increased lanes.

In addition, waste asphalt is inevitably generated during milling and crushing of roads during water and sewage and communication cable construction, as well as repair of the road itself.

In addition, as the population increase and the urban concentration of the population accelerates, the reconstruction of buildings is being actively conducted, and filling materials are inevitably generated even when the buildings are demolished.

If such waste asphalt or filler is left unattended, the environment will be polluted. Therefore, it will be collected at the construction site and transported to the workplace where the shredding device is installed, shredded to an appropriate size, and then disposed of in the landfill.

However, the landfill site has not only a limited capacity for landfilling, but also faces a problem of complaints caused by residents living near the site of the landfill site during the site selection process. It is following.

In addition, since the remaining resources such as crude oil and aggregates, which are raw materials of asphalt, are limited in the future, they are depleted in the future, and thus the problem of recycling resources can prevent economic pollution and at the same time obtain economic advantages.

In particular, the recycling of waste materials can reduce the initial development cost of resources, and thus economical in terms of producing materials.

Therefore, if recycled waste materials such as waste asphalt and fillers are recycled and used, they can not only overcome the environmental pollution problems caused by these waste materials and the difficulties associated with selecting landfill sites, but also secure raw materials production costs and aggregates for civil construction. Difficulties can also be solved.

In this regard, as a device for reusing waste asphalt or a filler, "Asphalt Recycling Device" in Korean Utility Model Registration No. 191802 and "Asphalt Concrete Recycling Device" in Patent Registration No. 412067 are known.

The former device can be mounted in a vehicle, and a plurality of rotating drums supported by a support roller to rotate with the power of a motor communicate with each other through a connecting plate including a burner, and the upper part of the rotating drum inlet side is closed into the rotating drum. A storage unit for storing asphalt fragments is installed, and a guide slope for guiding the waste asphalt fragments supplied from the storage unit into the rotary drum is installed at the inlet side of the rotary drum, and the waste asphalt fragment broken into a predetermined size is provided in the rotary drum. It is input.

The latter device is provided with a hot air duct for preventing direct transfer of the flame of the burner to the waste asphalt injected into the inner side of the rotating drum composed of a single body, and the waste heat of heating the ascon on the rear end of the rotating drum. Waste heat ducts are installed to guide the reuse of the wastewater, and the agitating means for discharging and discharging the recycled particles discharged through the discharge hole and the discharge hole through which the recycled ascon particles are discharged to the outside is provided at the lower end. As it is installed, it is possible to improve the risk of internal explosion and fire as the flame of burner is directly transmitted by applying heat to waste asphalt using indirect heat of burner, and to improve thermal efficiency by reusing waste heat used for heating. Will be.

The above-mentioned conventional apparatus is a device for totally reusing waste asphalt, so that a burner device must be installed to impart cohesiveness to the waste asphalt, so that the manufacturing cost is relatively high, and the waste asphalt is heated to about 150 to 180 ° C. As a result, harmful volatiles solidified in asphalt evaporate and carbon dioxide is generated, causing secondary air pollution, and concrete or soil generated at construction sites have to be treated separately.

In addition, the heat regeneration method uses heat in the regeneration process, and the use of energy is inevitable. As a result, the asphalt undergoes an oxidation reaction with oxygen in the air and loses its elasticity and hardens to exhibit sufficient strength. Therefore, the heat regeneration apparatus requires thorough temperature control from production to transportation and construction, and the production is extremely limited because such work management is not easy.

An alternative to solve the problems caused by the heating regeneration apparatus for manufacturing road pavement is to mix the pavement mixture at room temperature with cement, polymer emulsifier, and filler without heating the waste asphalt shredded to 40mm or less. To prepare. Here, the most important thing is related to the chemical function of the emulsifier. These emulsifiers determine the properties of the mixture for normal temperature packaging, and further determine the strength and compatibility of the packaging material.

Therefore, the present invention is to exclude the heating method for the waste asphalt and the filling material collected at the construction site in regenerating the waste asphalt, and to aim for the regeneration method at room temperature, so that it can be mixed with the emulsifier in the optimum weight ratio Can recycle the construction materials into construction materials, which can reduce the cost of producing raw materials and building aggregates, including environmental pollution caused by waste materials and landfill site selection, as well as waste asphalt and waste concrete. To provide a recycling apparatus using.
