The collection box 630 is formed to have a space corresponding to the falling distance of the foreign matter by the specific gravity.

The collection box 630 is not necessarily installed, but is selectively applied as necessary. When the collection box 630 is not applied, foreign matters having a small specific gravity scattered by the blower 600 are naturally dried on the ground and collected.

Referring to the operation of the present invention configured as described above is as follows.

As shown in Figure 2 to 6, by inputting the construction waste and crushed by a known crusher and put into the vibrating screen 500 to separate only the aggregate having a predetermined particle size. On the conveyor 510 for injecting the aggregate into the vibrating screen 500, a separate foreign matter treatment means 520 is installed so that only foreign matter in the aggregate is selected so that input of manpower required for hand picking is performed. I can eliminate it.

Referring to the operation of the foreign material processing means 520, when the rotary shaft 521 is rotated opposite to the conveying direction of the conveyor 510, a plurality of separation blades 523 protruding from the rotary shaft 521 selects vinyl, waste wood, etc. . At this time, the separation blade 523 is to separate the foreign matter without damaging the belt by the soft material 523b connected to the end, the foreign matter treatment means 520 can be installed in a plurality spaced apart. In addition, the foreign matter collected on the separation blade is a blower 600 toward the floating material remover 300 through a separate conveyor installed in the transverse direction with the waste moving conveyor 510 in the rotary drop direction of the foreign matter treatment means 520. ) Move to installation position and separate by specific gravity.

Then, the aggregate separated from the foreign matter before being introduced into the vibrating screen 500 as described above is sorted by particle size while passing through the vibrating screen 500, the aggregate is dropped into the wash water of the washing tank (100).

At this time, the water or air is three-dimensionally sprayed in the X, Z, Y axis direction by the first, second, third injection pipe 410, 420, 430 of the buoyancy separation means installed in the washing tank 100 The wash water forms a vortex to completely separate the foreign matter contained in the aggregate and float it on the water surface. That is, the buoyancy separation means, the first injection pipe 410 having a plurality of nozzles (410a) is the water (washing water supplied from the washing water tank 100) in both sides of the washing water filled in the washing water tank (100) The second injection pipe 420 having a plurality of nozzles 420a is configured to spray water (washing water supplied from the washing water tank 100) toward the floating material remover 300 at a position deposited on the surface of the water. And, the third injection pipe 430 having a plurality of nozzles (430a) is to spray the water (washing water supplied from the washing water tank 100) toward the floating material remover (300). Buoyancy separation means is almost no discharge of the washing water by receiving the injection in the washing water tank 100, the fine water can be discharged with the aggregate, so that the washing water can be supplied from the sedimentation tank through the washing water supply pipe 440. .

In this case, the nozzle 410a of the first injection pipe 410 is installed to have an inclination toward the upper portion on the horizontal line, that is, the inclination toward the floating material remover while facing the water surface, and the second injection pipe 420 has a plurality of penetrations. It is provided on the bottom of the shaded cover 425 having the ball 425a to prevent clogging of the nozzle 420a.

Subsequently, the aggregate that is settled in the state where the foreign matter is separated by the buoyancy separation means is moved on the conveyor 200 is installed inclined inside the washing tank 100 is introduced into the next process.

The foreign matter separated from the aggregate by the buoyancy separation means is discharged by being filtered by the suspended solids remover (300).

The foreign matter floating in the washing water is delivered from the washing water tank 100 by the floating material remover 300 that rotates in a counterclockwise direction (based on FIG. 2), wherein the washing water contained in the foreign matter is a through hole (311a, 312a). Or fall through the washing bar (312a) to the washing tank 100 is not discharged to the outside, the washing water dropped inside the floating material remover 300 to return to the washing tank (100) through the return pipe (330a) Alternatively, the washing water tank 100 at the lower end of the floating material remover 300 may be formed as an inclined surface to naturally enter the washing water tank 100.

The foreign matter discharged to the outside by the floating material remover 300 is separated by the specific gravity through the blower 600, the drop is moved, and the foreign matter (wood, etc.) with a large specific gravity among the foreign matter falls to the conveyor 340, the specific gravity Small foreign matter (such as vinyl or styrofoam) is allowed to be deposited on the collection box 630 or the ground inside the separation space 610 and then dried naturally.

According to the present invention, when the finally sorted foreign matter is separated by water as much as possible when separated by the floating material remover 300, only the foreign matter falls to save the process and time for removing moisture from the foreign matter, as well as buoyancy separation means By the operation of the first, second, and third injection pipes (410, 420, 430), the soil and the like are completely removed from the foreign matters, and the soil and water content in the foreign matters are greatly reduced, thereby greatly reducing the secondary processing costs such as drying, transportation, and incineration. It is possible to greatly improve the quality of the recycled aggregate possible.

According to the present invention having such a configuration, it is easily applied to the process of washing the aggregate and automatic sorting of the waste, minimize the amount of water used to separate the foreign matter, minimize the waste of water, when digging and crushing construction waste It is to completely separate the foreign matter in the aggregate included and to discharge the substance quickly to maximize the efficiency of the work and the quality of the recycled aggregate.

In addition, by automatically selecting the foreign matter in the aggregate by automation to minimize the personnel input for the selection of foreign matter.

In addition, when the soil is discharged to remove the foreign matter to minimize the content of water to minimize the cost of the secondary treatment of the foreign matter.

In addition, by the buoyancy separation means of the washing tank is to ensure that the foreign matter is always collected in a certain direction to move to the floating material eliminator side so that there is no suspended material on any one side on the water surface.
