By moving along the duct, it is collected and removed by the debris removal unit, so that only pure aggregates from which debris is removed can be obtained, and environmental pollution can be reduced by preventing the spread of fine dust in the process of removing debris. It would be.

In general, various kinds of wastes are generated during the dismantling of buildings, and soils, waste concrete, rebar, plastics, textiles, styrofoam, waste wood, vinyls, and papers are mixed in the generated wastes.

Among such construction wastes, such as concrete can be recycled as recycled aggregates, thereby separating the recycled aggregates from the construction wastes so that recycling can be made effectively, thereby reducing the cost of purchasing recycled aggregates and reducing environmental damage.

As a sorting method for sorting recycled aggregates from construction wastes, it is common for a worker to visually identify wastes in a hopper in which construction wastes are stored, and separate them into concretes, rebars, plastics, styrofoams, woods, papers, and vinyls by hand. to be.

However, the sorting of various kinds of wastes by hand is a primitive method, and the sorting process takes a long time because the sorting process is very inconvenient and cumbersome, and requires a lot of manpower. .

The process of selecting only pure aggregates from among aggregates containing foreign substances using the foreign substance sorting system configured as described above is as follows.

First, the waste is crushed using a crusher and the like, and the aggregates from which the earth and sand contained in the crushed matter are removed through the screen sorter are fed through the motor 11 and the driving sprocket rear 111 and the driven sprocket wheel ( When introduced into the drum 3 which is rotated by the rotating means 1 composed of the 112 and the chain 113, the injected pulverized product is caught in a plurality of vertical improvement protrusions 31 formed in the inner periphery of the drum 3. It is moved from the bottom to the top in a state, and the pulverized material moved to the top is dropped to the bottom by its own weight.

Next, as the falling down to repeat the process of crushing the aggregates (aggregates) between the edges of the crushed object is improved in the vertical shape due to wear and at the same time moved to the upper side by the inclination of the spiral guide (32) further wear As a result, high quality aggregates can be obtained.

In addition, as the air of the blower 8 is supplied through the first nozzle 5 in the process of the pulverized material moved upward, the foreign matter having a light weight does not fall to the lower part of the drum 3 without being dropped into the drum ( 3) it moves directly to the outlet side of the drum 3, the foreign matter coming out of the outlet side of the drum (3) is directed to the inside of the second duct (63) perpendicular to the air pressure of the second nozzle (5 ') is injected upward from the bottom Will move upwards.

On the other hand, the pulverized product coming out of the exit side along the inner periphery of the rotating drum 3 falls to the bottom by its own weight and falls on the upper surface of the discharge conveyor 4 'taking the form inserted in the lower part of the frame 2. Therefore, they move outside and gather at a specific place. That is, the foreign matter that is not separated in the course of the pulverized product falling from the outlet side of the drum 3 to the discharge conveyor 4 'is discharged by the second duct as described by the air pressure supplied by the second nozzle 5'. As it moves upward through 63 it is possible to obtain more pure aggregates.

Next, the foreign matter moved to the upper portion of the second duct 63 is moved to the lower side of the first space 711 through the inclined third duct 64 to the fourth duct 65 formed thereon. As the direction changes rapidly during the movement, waste wood chips, vinyl, plastic, paper, and the like, which are large foreign matters, are moved downward along the first discharge hopper 713 by the acceleration or the vacuum force therein. The foreign matter moved along the discharge hopper 713 is moved to the outlet side by the first conveying screw conveyor 712 rotated in the lower portion and is discharged in a state of being crushed by a certain amount by the rotary grinder 714 in a predetermined place Collect and process.

Next, the air containing the foreign matter having a large mass passes through the vibration separation unit 71, and after the foreign matter is removed, the air is moved to the second space portion 73 through the fourth duct 65 located thereon.

Next, only the foreign matter having a large mass is removed from the air moved to the second space portion 73, and the small amount of fine powder or earth and sand is contained, and the foreign matter having a small mass is separated through the process as described above. The separated foreign matter is collected and treated as it is discharged to the outside through the second discharge hopper 713 ', the second transfer screw conveyor 712' and the rotary valve 715 formed at the lower portion of the second space portion 73. Just do it.

At the same time, the foreign matter moved to the upper part passes through the filter 74 again, and fine foreign matter remaining in the air is removed, and the air from which the foreign matter is removed is sucked to the suction side of the blower 8 connected to the upper space, and then the first As it is discharged through the duct 61, it is possible to prevent the fine dust and the like from scattering outside by circulating the inside without separately inhaling the outside air.

On the other hand, in the present invention was used to have a form in which the inclination of the drum (3) for the transfer from the inlet side to the outlet side to improve the shape of the aggregate contained in the pulverized product and at the same time as the outlet side, as shown in Figures 6 and 7 As can be seen, the drum 3 can be used to be horizontal, or to take the form of which the slope becomes lower toward the exit side.

Thus, the present invention is crushed or aggregated by a plurality of projections and spiral guides formed in the inner periphery in the process of passing through the drum in which the aggregates contained therein dust removed therein through the screen sorting machine By hitting each other to improve the shape, there is an effect to obtain a large amount of good aggregates.

In addition, foreign matters such as waste wood pieces, fabric pieces, plastics, papers, vinyls, etc., contained between the pulverized materials are collected or removed by a plurality of foreign material removal units while being transported along the duct by the high-pressure air injected from the nozzle. In addition, it is effective to obtain only pure aggregates from which foreign substances have been removed.

In addition, it is possible to prevent the contamination of the surrounding environment by preventing the fine dust from being scattered to the outside by separating the air for separating the foreign matter from the pulverized material by the air circulating therein instead of inhaling it from the outside. There is one more effect.
