In the present invention, the impingement member 3 is alternately provided alternately to the first and second internal partition plates 11a and 11b while descending downward in the vertical direction. That is, when the crash inclining member 3 is provided on the first inner partition plate 11a and protrudes toward the central space of the lower case member 10 as shown in the figure, the collision inclining member 3 Is integrally provided in the second inner partition wall plate 11b so as to protrude from the second inner partition wall plate 11b toward the central space of the lower case member 10. [ Since the plurality of collision slant members 3 are provided in this manner, the upward slanting plates 31 of the impingement member 3 alternately transversely on both sides in the vertical direction have opposite downward slant directions.

The wind induction plate 4 may be provided below each of the impact collision members 3 as required. The wind induction plate 4 is formed integrally with the inner partition plates 11a and 11b by a plate member having an upward inclination inclined upward toward the center space in the inner partition plate as in the lower inclination plate 32, The plate (4) is provided facing the lower surface inclined plate (32) with a gap therebetween. When the wind induction plate 4 is provided, as will be described later, the wind blown out through the air outlet flows between the wind induction plate 4 and the lower inclination plate 32 of the impact warp member 3, So that it can be made more efficient to blow the lightweight foreign matter into the foreign matter discharge portion by such strong air blowing.

A "foreign matter discharge portion" is formed between each of the collision-inclinational members 3 in the first and second internal partition wall plates 11a, 11b. Specifically, the first impingement member 3 is located on the first inner partition wall plate 11a from the top to the bottom, the air induction plate 4 is located thereunder, A plurality of collision inclined portions 3 are installed in such a manner that a second collision incline member 3 is spaced apart from the upper collision inclined portion 3 of the collision incline member 3, There is a "foreign matter discharge portion" opened in the form of being cut in the first internal partition plate 11a in the interval between the swash plates 31. [ The dropping space between the first inner partition plate 11a and the first sidewall 101a communicates with the central space of the lower case member 10 at the position where the foreign matter discharge portion exists. The second inner partition wall plate 11b and the second inner partition wall plate 11b are formed in the same manner as the first inner partition wall plate 11a described above, The lower space of the lower case member 10 communicates with the lower space. At this time, in the foreign matter discharge portion, the wind induction plate 4 can be extended to the space between the inner partition plate and the side wall of the lower case. The angle of inclination of the wind guide plate 4 may be the same as or similar to the inclination angle of the upper surface swash plate 31 of the impact-inducing member 3 located on the opposite side.

Each blowing port 5 is connected to a blowing pipe 50 and the blowing pipe 50 communicates with the outside of the lower case member 10. [ If necessary, the first and second side walls 101a and 101b of the lower case member 10 suck lightweight foreign matter W flowing into the 'falling space' And a suction duct 18 communicating with the external discharge port 180. The suction duct 18 may be connected to the external discharge port 180, When the external outlet 180 and the suction duct 18 are provided, a part of the lightweight foreign matter W that has flowed into the falling space through the "foreign matter discharging portion" passes through the external outlet 180 and the suction duct 18 And the lightweight foreign matter W that has not been sucked into the outside outlet 180 is dropped into the falling space.

Below the lower case member 10, a collecting unit 130 can be communicated. The collecting unit 130 includes a central funnel communicating with the "central space" of the lower case member 10, And a peripheral funnel communicating with the "falling space" between the inner partition plates 11a and 11b and the first and second sidewalls 101a and 101b. Therefore, aggregate and lightweight foreign matter falling into the central space and falling space are collected separately.

FIG. 9 is a schematic side view of the state shown in FIG. 3, that is, a schematic side view showing a state in which one side wall is omitted in order to show the internal structure of the foreign matter removing apparatus 100 for construction waste of the present invention .

The construction waste reclaimed stone S put into the discharge port 21 is first introduced into the rotary impact crushing unit 120 to be rotated And is hit by the impact hammer 220 of the impacting body 22 to collide with the crushing plate 23. In this process, lightweight foreign matter (W) such as leaves, styrofoam, and wood chips attached to the aggregate surface of the construction waste slag (S) is separated from the aggregate surface, and the clay clusters and the binder hardened together with the lightweight foreign matter (W) In the presence of residues, such clay and binder hardening residues are also broken, so that lightweight foreign matter is separated from recycled materials such as aggregate and soil, and binder hardening residues are also separated from recycled materials (such as aggregates). That is, the construction waste discard S is in a state where the lightweight foreign matter W is mixed with the aggregate or the like in a form that can be easily removed by separating from the aggregate or the like. The construction waste stones S that have collided with the crushing plate 23 flow down in accordance with the inclination of the crushing plate 23. In this process, the striking hammer 220 of the rotary striking body 22 is moved to the construction waste stones S ) May be pressed to further crush the clay of the surface, binder hardening residues, and the like.

The construction waste stones S falling from the crushing plate 23 collide with the upper surface swash plate 31 of the impingement member 3 existing at the uppermost position of the first inner partition wall 11a and then travel along the upper surface swash plate 31 It drops down after falling down. The impact reclining member 3 protrudes but only partially blocks the entire central space of the lower case member 10 so that the construction waste reclaimed stone S flowing down along the upper surface inclination plate 31 falls again.

At this time, when a strong airflow is generated through the air blowing port 5 connected to the blowing pipe 50, the wind is blown by the gap between the lower inclined plate 32 of the impingement member 3 and the wind induction plate 4 facing the lower inclination plate 32 So that the upper case member 10 is strongly urged toward the center space of the lower case member 10. Therefore, the lightweight foreign matter W such as leaves, styrofoam, wooden debris, and the like contained in the construction waste discard S flowing down along the upper surface inclination plate 31 is blown by the blowing air and is discharged through the foreign matter discharge port formed on the opposite side, Falls into the falling space between the second inner partition wall 11b and the second side wall 101b of the lower case member 10 and drops downward in the "falling space". The aggregate and soil heavier than the lightweight foreign matter W do not go out to the foreign matter discharge port despite the blowing and fall down continuously in the central space of the lower case member 10. [

Such an action also occurs in the collision gradient member 3 existing in the second inner partition wall 11b. In other words, in the above description, the construction waste stones S that continue to fall down from the central space of the lower case member 10 without leaving the foreign matter discharge port despite the blowing air are subsequently present in the second internal partition wall 11b And then falls down and flows downward along the upper surface inclined plate 31. The lower case member 11a is then lowered through the air outlet 5 existing in the second inner partition wall 11b, 10 and the lightweight foreign matter W contained in the construction waste stones S falling down therefrom is discharged to the opposite side, that is, the foreign matter discharge port Falling space "between the first inner partition wall 11a and the first sidewall 101a through the first inner partition wall 11a and then falls down there.

As described above, the wind guiding plate 4 facing the lower guiding plate 32 of the impact guiding member 3 can be provided. In this case, the guiding plate 5 is provided on the lower guiding plate 32 and the wind guiding plate 4, The wind from the air outlet 5 is guided so as to flow strongly with an upward tilt along the interval between the swash plate 32 and the wind guide plate 4 so that the lightweight foreign matter W So that the foreign matter can be discharged more efficiently toward the discharge port of the foreign object.

In the present invention, the falling of the construction waste stones (S) as described above, the collision with the impact collapse member (3), and the discharge of the lightweight foreign matter (W) 11b) alternately.

The lightweight foreign matter W that has flowed into the dropping space falls into the dropping space. When the external discharge port 180 and the suction duct 18 are provided, a part of the lightweight foreign matter W that has flowed into the dropping space flows into the external discharge port 180 And the suction duct 18, and is discharged to the outside.

 Finally, the final processed product of the construction waste discarded down through the central space of the lower case member 10 is gathered through the central funnel of the collecting unit 130, flows into the falling space through the foreign matter outlet, Lightweight contaminants are gathered through the surrounding funnel and treated safely.

As described above, according to the present invention, since the foreign substances are removed from the aggregate due to the collision and the foreign matter is removed repeatedly by the blowing in the falling process, it is included in the construction waste slag S, It is possible to separate and remove the foreign matter very effectively from the aggregate or the like of the construction waste so that the construction waste can be recycled as a useful resource.

Particularly, in the present invention, since dust and the like are not blown out to the outside, even when the wind force useful for removing foreign matter is used many times in multiple stages, it is possible to effectively prevent adverse effects on the surrounding environment due to scattering of dust and the like, The effect of the present invention can be further improved.
