The present invention relates to a construction waste regeneration treatment method for screening aggregates from construction wastes and to a sorting apparatus thereof, and in particular, to remove and remove impurities contained in recyclable aggregates in construction waste shredded to an appropriate size. It relates to a construction waste sorting and separating device.

Many structures, such as bridges, roads, and other buildings, which have been created in the process of urbanization and industrialization, are gradually aging over the years, and in recent years, reconstruction and redevelopment has been actively promoted in many regions to improve the living culture. It is a reality.

In the process of dismantling, reconstructing, and redeveloping old structures, many construction wastes are generated. If the construction wastes are reclaimed, landfills are not only difficult to secure, but also have a high landfill cost and have an enormous impact on the environment. Various measures have been taken to recycle the construction wastes in two aspects: the recycling of resources along with the protection of the natural environment, and various treatment devices for construction wastes have been developed in Korea.

Construction waste can be classified into mixed impurities including waste wood, waste synthetic resins such as styrofoam, metals such as rebar, waste papers, and waste fibers used as cement reinforcement. Wastes are separated for incineration and regeneration through treatment process, and in recent years, in order to replenish aggregate resources which are inadequate, there is a high interest in separating and recycling aggregates from construction waste.

The present invention relates to an apparatus for sorting and separating construction waste which can be sorted by the particle size of recycled aggregate while easily separating impurities such as waste wood, styrofoam, waste paper, and waste fibers by crushing construction waste. .

As a treatment apparatus for producing recycled aggregates of construction wastes, which have been conventionally used, are disclosed in Korean Utility Model Publication No. 20-0264696, Korean Patent Publication No. 10-05-18077, and the like.

Conventional production equipment for the regeneration of construction waste is generally vibrated by separating the metal materials such as rebar while going through the magnetic separator, which is a metal iron separator, in the process of crushing the construction waste materials by jaw crusher and transporting them by conveyor. The soil is separated by the screen, and then put into the hopper to drop or fall directly from the conveyor belt to form a structure for separating some light waste by the blower, as shown in FIG. Like the blower driven by the motor (3) adjacent to the lower end of the conveying conveyor (2) in the input portion in which the construction waste (10) falls through the conveyor belt (2) in the water collecting tank (1) 4) Blowing duct so that the wind conveyed from the crushed waste concrete can be blown intensively to the falling part The end portion 6 of (5) is located, and on the opposite side of the end portion 6, low specific impurities in the crushed construction waste 10 falling to the water collecting tank 1 by wind are collected and discharged separately to the outside. It can be seen that there is a structure in which the suction part 7 of the guide duct 8 is installed and a discharge mechanism 9 for discharging the washing aggregate in the collection tank 1.

The conventional treatment apparatus for producing recycled aggregates of construction waste configured as described above separates impurities in advance by the wind power of the blower 4, and the crushed construction waste 10 falling into the collection tank 1 also depends on the falling position. Since specific gravity separation can be performed, it is effective to increase the efficiency of separating impurities from recycled aggregates. However, the above-mentioned main treatment devices, that is, wind blowing facilities, which are wind separators, and auxiliary equipment for treating dusts according to the supply, Along with this, there was basically a problem that the land had to be excessively occupied.

In addition, in the blower according to the conventional method, when the strength of the wind is structurally reduced, only a small amount of light waste is blown out, and a rather large waste such as waste wood or waste resin cannot be separated properly. If it is hardened, relatively large wastes such as waste wood and synthetic resin can be separated and sorted, but at the same time, reusable fine aggregates fly away, which means that there is no meaning of recycling and adversely affects the work environment such as dust scattering. There was.

The present invention has been made in view of the above problems, and an object of the present invention is a facility for sorting and separating recycled aggregates and impurities introduced by crushing construction waste, and inputting crushed waste concrete to be treated into an immersion tank. It provides a means to float the impurities to be sorted, removed inside the immersion tank to be discharged to the outside by the suspended matter discharge means, and the cleaning aggregate from which impurities are removed is configured to be discharged to the outside by a separate sediment discharge mechanism It aims to provide a construction waste treatment apparatus.

It is another object of the present invention to provide a sorting and separation method and apparatus for reducing the production cost of recycled aggregates by efficiently sorting and separating recycled aggregates and impurities.

In order to efficiently sort and separate the recycled aggregates and impurities, the waste concrete that is crushed into the immersion tank filled with water is introduced, and an induction discharge device is installed to discharge the impurities suspended in the immersion tank to the outside, In the construction waste sorting apparatus and method, in which the recycled aggregate from which impurities are removed is operated to be externally discharged by a separate discharge mechanism, the crushed pulverized product falling from the conveyor or the waste input hopper to the top of the submerged tank is conveyed. A step to prevent the escape of the chute is installed to the waste concrete crushing step is installed, and a high-pressure spray pipe for ejecting high-pressure compressed air and spouting water is installed inside the immersion tank is a high-pressure compressed air and spouting water Vinyl buried together with the waste concrete while spraying the waste concrete crushing Light impurities such as wood and styrofoam are to be floated to the upper part, and a separate induction discharge device is installed to induce and discharge the injured impurity to the outside to discharge the impurity to the outside. In order to form a gentle slope, the conveying chain conveyor discharge mechanism is installed in the same direction as the bottom surface to transfer sediment and washing aggregate. The chain conveyor uses steel conveyors and attaches belts to the chain conveyors. Is fixed to a flat iron, and a conveying blade that functions as a scraper at regular intervals of the conveyor is installed at a certain angle. When the chain conveyor is upward, it carries out the function of transferring the washing aggregate to the outside, and when the chain conveyor is directed downward, To perform the scraper function by pushing down the sludge that may be deposited It provides a method for treating construction waste sorting comprising the step of operating and the apparatus.

In addition, the injured impurity induction discharge device of the present application forms an induction channel for guiding foreign substances and provides a device for U-turn discharge by the chevron induction device.

In addition, the transfer blade having a scraper function installed in the sediment discharge mechanism of the present application attaches an elastic rubber plate to a certain height so that the sediment and washing aggregate are efficiently transferred when the chain conveyor is upward, and the rubber plate is flooded when the chain conveyor is downward. Provides a construction waste recycling aggregate treatment device is installed at a height that maintains the gap between the bottom of the tank so as not to accumulate sludge.

In order to implement the above technical concept will be described with reference to the drawings presented as an embodiment of the present invention.

The end portion 6 of the blower duct 5 is located, and the low specific gravity impurity in the crushed construction waste 10 falling to the collection tank 1 by wind power on the opposite side of the end portion 6 is collected and collected. The suction unit 7 of the guide duct 8 for discharging to the outside separately is installed, the collection tank (1) inside has a discharge mechanism (9) for discharging the washing aggregate, the conventional construction waste recycling treatment Device Forming illustrates the prior art.

The conventional treatment apparatus for producing recycled aggregates of construction waste configured as described above separates impurities in advance by the wind power of the blower 4, and the crushed construction waste 10 falling into the collection tank 1 also depends on the falling position. Since some specific gravity separation can be performed, the efficiency of separating impurities from the recycled aggregate can be increased, but with the above main treatment devices, that is, a wind blowing unit, which is a wind separating device, and also an auxiliary facility for treating dust caused by the blowing Basically, the land had to be overcrowded.

Since the conventional construction waste recycling aggregate treatment device separates impurities by the wind power of the blower, the present invention entails their main processing devices, that is, a wind blowing unit, a blower facility, and also an auxiliary facility for treating dust from the blower. It basically solves the problem of over occupying the site, and in the blower according to the conventional method, when the strength of the wind is structurally reduced, only a small amount of waste is blown out. Waste materials cannot be separated properly, and if the wind strength is strong, relatively large waste materials such as waste wood or synthetic resin can be separated and sorted, but at the same time, reusable fine aggregates are blown together, resulting in low recycling efficiency and dust scattering. There were many problems that adversely affect the working environment.
