In describing the present invention, the terms or words used in the present specification and claims are based on the principle that the inventor can appropriately define the concept of the term in order to best describe his or her invention. It should be interpreted as meaning and concept consistent with the technical idea of

As shown in FIG. 1 , the system 1 of the present invention is a belt-driven method that receives and transports recycled aggregate containing foreign substances in the first transfer unit 31 and the first transfer unit 31 in which an upward slope gradient is formed. a tripper conveyor 3 composed of a second transfer unit 32 in which a downward drop is formed; The blower 51 and the blower 51 are connected to the blower 51 and the blower pipe 52 through which the wind flows from the blower 51 and the blower pipe 52 are in communication with the first conveying part 31 and the second conveying part 32 Blower (5) including an injection pipe (53) for spraying wind on recycled aggregate containing foreign substances falling between; A suction hole 621 is formed at a position opposite to the injection pipe 53, and a suction pipe 62 through which foreign substances separated from recycled aggregate including falling foreign substances are mixed with the wind and flow, and the suction pipe 62 It is characterized in that it includes; a separation unit (6) including a cyclone (61) connected to one side to separate the foreign material by the vortex from the inside and discharge downward, and discharge the wind from which the foreign material is separated upward.

Here, in the recycled aggregate containing foreign substances, recycled aggregate is a concept that includes recycled aggregate and soil, and foreign substances are a concept that includes various materials that cannot be used because they are mixed with recycled aggregate such as wood chips, vinyl, and wire.

As shown in the drawing, the tripper conveyor 3 allows the recycled aggregate containing foreign substances flowing upward by the first transfer unit 31 to fall and flow to the second transfer unit 32, as shown in the drawing. 31) to the second transfer unit 32, in the process of falling of the recycled aggregate containing the foreign material is to separate the foreign material by the blowing of the wind by the injection pipe (53).

In addition, as shown in FIG. 1 , an inflow conveyor 2 that delivers recycled aggregate containing foreign substances to the front end of the first transfer unit 31, and the second transfer unit 32, the rear end of the second transfer unit 32 includes recycled aggregate from which foreign substances are removed. The discharge conveyor (4) to be discharged to be further configured.

The operation mechanism of the tripper conveyor 3, the inlet conveyor 2, and the discharge conveyor 4 can be applied to various known technologies, and thus detailed description thereof will be omitted.

However, in the tripper conveyor 3, the first transfer unit 31 is not shown in detail in the drawings, but a plurality of carrier rollers are configured. It is reasonable to use a small wide roller to spread the recycled aggregate as wide and thin as possible so that the separation efficiency of foreign substances by wind blowing is increased.

The blower (5) is connected to the blower (51) and the blower (51) and communicates with the blower pipe (52) through which wind flows from the blower (51) and the blower pipe (52), and the first conveying part (31) and It characterized in that it comprises a spray pipe 53 for spraying wind to the recycled aggregate containing the foreign material falling between the second transfer unit (32).

The wind flowing to the blower pipe 52 by the blower 51 is blown in the direction of the suction hole 621 through the injection pipe 53 positioned between the first conveying part 31 and the second conveying part 32. As mentioned above, by this spraying, foreign substances are removed from the recycled aggregate containing foreign substances falling between the first conveying part 31 and the second conveying part 32, and the wind mixed with the foreign substances is sucked. It is to be introduced into the ball 621 .

The separation unit 6 is a suction pipe 62 through which a suction hole 621 is formed at a position opposite to the injection pipe 53 and the foreign material separated from the recycled aggregate containing the falling foreign material is mixed with the wind and flows; , the suction pipe 62 is connected to one side to separate foreign substances by a vortex from the inside and discharge downward, and a cyclone 61 for discharging the wind from which the foreign substances are separated upwards.

The wind mixed with foreign substances through the suction pipe 62 flows into one side of the cyclone 61 to form a vortex inside the cyclone 61 . A foreign material having a large specific gravity by this vortex is discharged downward of the cyclone 61, and the wind from which the foreign material is removed is discharged upward.

Here, since the cyclone 61 can be applied to various known technologies, a detailed description thereof will be omitted.

On the other hand, when blowing by the blower 51, when external air is introduced into the blower 51 to make the blowing, scattering is generated in this process, and foreign substances such as dust may be mixed in the blowing wind. In the case of spraying through the pipe 53, the separation efficiency of foreign substances from the recycled aggregate containing the falling foreign substances will be lowered due to the inclusion of foreign substances in the wind itself, and the external environment will be polluted by the scattering itself generated in the blowing process.

Accordingly, in the present invention, the separation unit 6 further includes a circulation pipe 63 through which the wind from which the foreign matter discharged upward from the cyclone 61 is separated is introduced and transmitted to the blower 51 . present.

That is, the wind from which foreign substances are removed by the cyclone 61 is discharged upward, and this wind is circulated to the blower 51 through the circulation pipe 63 to spray pure wind from the recycled aggregate containing the falling foreign substances. It is to improve the separation efficiency of foreign substances and to control scattering during the blowing process.

In the present invention, as shown in FIG. 1, the first transfer part 31 has a spread part 8 that uniformly spreads the aggregate containing foreign substances flowing upward to the upper part so that the spread part 8 is further configured. The reason for uniformly spreading the aggregate containing the foreign material flowing in the first transfer unit 31 by the spread unit 8 is to make it easier to separate the foreign material by the blowing of the wind.

2 shows an embodiment of the spread part 8, the spread part 8 of this embodiment includes a pair of supports 81 protruding upward from both sides of the first transfer part 31, and the support It is characterized in that it includes a rotary sphere 82 mounted to enable rotational interlocking at (81), and a brush portion 83 formed by protruding a plurality of fiber yarns on the outside of the rotary sphere 82.

The rotary sphere 82 is automatically rotated by the recycled aggregate containing the flowing foreign substances, and the reason that the recycled aggregate containing the foreign substances and the brush unit 83 comes into contact is that the recycled aggregate containing the foreign substances flows backward. The brush unit 83 made of a plurality of fiber yarns while controlling ) itself to remove the foreign material, so that the foreign material is removed by the brush unit 83 even before the removal of the foreign material by the wind, thereby increasing the separation efficiency.

Here, the type of the fiber yarn is not limited.

In addition to this, as shown in FIG. 3 , the spread part 8 further includes a magnetic force part 84 to which a magnet is attached between the brush parts 83 , and the brush part 83 is formed by a plurality of fiber yarns. A first vinyl separation bar 832 having a ring formed at the end between the brush 831 and the fiber yarn is included.

In the spread part 8 of this embodiment, the magnetic force part 84 is formed between the brush parts 83 at a height lower than the brush part 83, so that foreign substances such as wire fragments are removed. Since the iron component has a large specific gravity, it is not easy to separate by wind at the rear end, so that the iron component foreign material is separated by the magnetic force unit 84 at the front end. The reason for configuring the height of the magnetic force portion 84 lower than that of the brush portion 83 is to control the magnetic force portion 84 from being damaged by direct contact with recycled aggregate or the like.

Also, in this embodiment, the brush unit 83 includes a first vinyl separation bar 832 having a ring formed at the end between the brush 831 made of a plurality of fiber yarns and the fiber yarns. As mentioned above, the brush 831 allows the adsorption of foreign substances by static electricity, but plastics such as vinyl are not easily adsorbed by the brush 831, so the first vinyl having a ring at the end. It is to filter the vinyl and the like from the recycled aggregate by the separation bar (832).

The first vinyl separation bar 832 is preferably made of an elastic material such as iron, and its height is lower than that of the brush 831 as shown in the drawing, so that it is appropriate to control direct contact with recycled aggregate and the like.

In addition to this, the spread part 8 further includes a vinyl stripping ball 85 , the vinyl stripping ball 85 having a fixing bar 851 protruding upward from the support 81 , and the fixing bar 851 . ), a fixing plate 852 that is mounted while forming a distance from the brush part 83, and a second vinyl separation bar 853 protruding downward from the fixing plate 852 and having a ring at the end is included. characterized.

As mentioned above, the first vinyl separation bar 832 filters the vinyl from the recycled aggregate containing the flowing foreign material and rotates. During the rotation process, the second vinyl separation bar located above the rotating hole 82 is The vinyl filtered by the first vinyl separation bar 832 by the bar 853 is filtered once again.

The reason that the vinyl stripping sphere 85 is configured in this way is that when the vinyl filtered by the first vinyl separating bar 832 continues to rotate, adsorption and separation of foreign substances by the brush part 83 and the magnetic force part 84 . Since the vinyl interferes with this, the vinyl filtered by the second vinyl separation bar 853 is detached.

The second vinyl separation bar 853 is also made of an elastic material such as iron, and it is reasonable that the first vinyl separation bar 832 and the second vinyl separation bar 853 are configured at a position where they do not interfere.

On the other hand, in the case of foreign substances deposited on the recycled aggregate, there is a problem that it is not easy to adsorb by the spread part 8, and it is not easy to separate by the wind at the rear end.

Accordingly, in the present invention, an embodiment for increasing the separation efficiency of foreign substances deposited on the recycled aggregate itself is shown in FIG. 4 .

In this embodiment, an example is provided in which a collision disengagement sphere 33 is further configured at the end of the first transfer unit 31 so that the foreign material is detached by a collision with the recycled aggregate containing the falling foreign material.

The collision disengagement sphere 33 is a fixture 331 and the recycled aggregate containing foreign substances falling while being fixed to the first transfer unit 31 by the fixture 331 is introduced into the upper surface and discharged to the lower surface, and is discharged to the inside. It is characterized in that it includes a body portion 332 comprising a collision plate 332-1 that forms a downward inclination gradient in a zigzag manner.

The fixture 331 is a configuration for fixing the body part 332 to the upper and lower part of the first transfer part 31. Although not shown in the drawings, the fixture 331 has a buffer structure by a spring, etc. It is reasonable to cushion the impact with recycled aggregate containing falling foreign matter. It goes without saying that various known technologies can be applied to the buffer structure.

In addition, the fixing angle of the body part 332 in the fixture 331 is also freely adjustable so that the recycled aggregate containing foreign substances falling to the lower part of the body part 332 is the suction hole 621 and the injection pipe. (53) is to fall between them. In this way, the structure in which the body portion 332 in the fixture 331 can freely adjust the angle can also be applied to various known techniques, and thus a detailed description thereof will be omitted.

The body portion 332 is a tubular shape with an open upper surface and a lower surface, and although not shown in the drawings, a groove is formed at the upper end so that the upper end of the first transfer unit 31 is embedded, and is dropped through the first transfer unit 31 It is necessary to control the outflow of recycled aggregate containing foreign substances to the outside.

A plurality of collision plates 332-1 forming a downward slope in a zigzag manner are configured inside the body 332, and the recycled aggregate containing falling foreign substances collides with each collision plate 332-1. In this process, in particular, foreign substances deposited on the recycled aggregate itself are detached, and in the case of bulked foreign substances adsorbed between foreign substances, they are crushed by collision to facilitate separation by wind at the rear end.

Those skilled in the art from the above description will be able to see that various changes and modifications are possible without departing from the technical spirit of the present invention. Accordingly, the technical scope of the present invention is not limited to the content described in the detailed description of the specification, but should be defined by the claims.
