Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction waste recycling apparatus and a recycling aggregate production method using the same,

More particularly, the present invention relates to a construction waste dismantling apparatus, and more particularly, to a construction waste dismantling and dismantling apparatus, and more particularly, to a dismantling apparatus for dismantling construction waste, And a method for producing a construction intermediate waste using the same.

As a result of the so-called development priority policy and the policy of high growth policy, the environmental problem, which is the reverse function in Korea, has been somewhat deviated from the subject of consideration.

However, as a result of this growth-oriented policy, the increase in waste and pollutants of the by-product has reached a pressing point that can no longer be delayed.

Especially, construction industry waste of various construction and civil engineering works shows a rapid increase, which is mainly caused by revitalization of redevelopment, reconstruction, and dismantling of structures, which is actively progressing recently due to aging and deterioration of urban and rural buildings do.

In this way, a large amount of construction waste is discharged due to aging of buildings. However, due to lack of landfill, illegal dumping, etc., destruction of natural environment is prevalent. In accordance with the Act on Promotion of Resource Conservation and Recycling, It is obligatory to recycle by-products.

As a result, several companies are producing recycled aggregate, but due to lack of technology and awareness, recycling of recycled aggregate is not mandatory, and each construction company avoids recycled aggregate, so recycled aggregate is limited to use as soil and embankment. Which is a waste of enormous resources.

In particular, cement paste (hereinafter abbreviated as "paste") is attached to the surface of the waste concrete, and the coating material of the chemical is coated on the surface of the waste ascon. Since the paste and the coating material lowers the quality of the recycled aggregate, it must be removed during the regeneration of the aggregate. Conventional construction waste recycling technology usually relies on pulverizing technology to adjust the size, so that the surface of the recycled aggregate is coated with paste and coating material to be. As such, the aggregate coated with the paste and the coating material is not used as an aggregate for a concrete mixer, but has a disadvantage that it can only be used for a simple landfill or an auxiliary soil layer.

In order to solve such drawbacks, there have been proposed techniques for removing the paste and the coating material by using a chemical agent, but the cost of using the chemical agent is constantly increased and the burden is increased and the environment can be contaminated .

The strength and the like of the finally produced recycled aggregate differ not only from the above-mentioned foreign materials such as paste, but also from the point of crushing the waste concrete in the past. Therefore, the final produced recycled aggregate has an angular shape , And the angular recycled aggregate has a weak strength and requires another material to reinforce the strength.

In order to solve such disadvantages, there have been proposed techniques for producing recycled aggregate of high quality by removing foreign substances such as cement paste and the like on the surface of pulverized waste concrete and improving the shape of the finally produced recycled aggregate to a curved shape.

However, the conventional art of manufacturing the recycled aggregate has a problem in that the aggregate is struck using a high-strength striking rod or the like, so that it is broken rather than peeling off the foreign matter.

Patent Document 1 (Registered Patent No. 10-1150700) discloses a pair of a shaft in which a shaft is installed inside a cylindrical housing in which an inlet for supplying recycled aggregate from a feed conveyor and an outlet for pulverizing and discharging recycled aggregate are formed, Wherein the housing has an upright wall vertically protruding upward from an end portion of the 12 o'clock direction and a 3 o'clock direction, Is connected to a motor pulley of a motor which is protruded from both sides of the housing at a hexagon angle and which provides a speed of 250 to 300 RPM from a pulley to a belt and is connected to a bushing provided on the outer diameter of the shaft by a fixing member, Three of which are located at different positions in the circumferential direction and which are provided with blades for applying a hitting force of 50 to 70 km / hr to the blade mounting portion at the tip, .; The separating device is uniformly arranged in the circumferential direction in the range of 3 to 6, and the recycled aggregate accumulated on the bottom of the housing is conveyed by the natural fall due to the scattering drop by repeating friction and striking several hundred times, And a blade connected to a pair of arm ends rotating integrally with the shaft inside the housing, hits the regenerated aggregate in which water is absorbed, and the fine aggregate of 5 to 25 mm and the fine aggregate and fine powder of 5 mm or less are discharged. , The paste attached to the surface of the recycled aggregate is completely peeled off by the friction and the impact generated when the recycled aggregate moves slowly to the discharge port by the repetition of the free fall,
