Next, the operation and effects of the shredding / selecting device for construction waste according to one embodiment of the present invention configured as described above will be described in detail.

First, when construction waste is input to the first shredder 110 through the first hopper 112, the construction waste is shredded by the first shredder 110 to discharge the first waste through the outlet of the first shredder 110. Foreign matter contained in the construction waste shredded by the first shredder 110 while being discharged onto the conveyor 120 and transported by the first discharge conveyor 120 (for example, a relatively large and long metal and waste wood) Etc.) are manually removed and dropped onto the 40 mm metal wire mesh 221 of the first sorter 130.

However, the belt 141 is suspended between the first driving wheel 140b fixed to the rotating shaft 140a of the first driving motor 140 and the first driven wheel 143 provided on the first eccentric shaft 142. As the first driving motor 140 rotates clockwise in FIG. 5, the first driving wheel 140b fixed to the rotation shaft 140a of the first driving motor 140 is clockwise in FIG. 5. Rotational force of the first driving wheel 140b is transmitted to the first driven wheel 143 through the belt 141 so that the first driven wheel 143 rotates clockwise in FIG. 5. The first sorter 130 swings while drawing an oval in a clockwise direction so that the aggregate and the foreign matter slide down.

Accordingly, the aggregate having a particle size of 40 mm or less in the shredded construction waste dropped from the first discharge conveyor 120 on the 40 mm metal wire mesh 131 of the first sorter 130 is the 40 mm metal wire mesh 131. ) 8 mm metal wire mesh 132 installed below the 40 mm metal wire mesh 131 so as to fall down, and fine powder having less than 8 mm of grain size and residing soil passes through the 8 mm metal wire mesh 132 to collect the fine powder Collected in the hopper 133 is discharged to the stone powder / xantho collection position by the stone powder / xantho conveyor 240 through the outlet of the stone powder / xantho collection hopper 133.

In addition, among the aggregates having a particle size of 8 mm to less than 40 mm that do not pass through the 8 mm metal wire mesh 132, an aggregate having a particle size of less than 8 mm to 25 mm is a 25 mm metal wire mesh 134 installed under the 8 mm metal wire mesh 132. And collected in the first aggregate collection hopper 135 by passing downward to the bottom, and having a particle size of 8 mm to less than 25 mm by the first aggregate discharge conveyor 250 through the outlet of the first aggregate collection hopper 135. Aggregate having a particle size of less than 25 mm to less than 40 mm that is discharged to an aggregate collection location and that does not pass through the 25 mm metal wire mesh 134 is collected in the second aggregate collection hopper 136 and the second aggregate through the discharge port. The discharge conveyor 260 discharges the particle size to the aggregate collection position of less than 25mm to 40mm.

Meanwhile, an aggregate having a particle size of 40 mm or more that does not pass through the 40 mm metal wire mesh 131 falls on the first introduction conveyor 170 according to the fluctuation of the first sorter 130, wherein the foreign matter sorter 150 Air is discharged through the air discharge pipe 153 and the water discharged through the spray pipe 153 through the air outlet 155a formed at the left end of the duct 155, thereby preventing dust generation and at the same time having a particle size of 40 mm. The foreign matter contained in the aggregate is blown to the first foreign matter scattering prevention plate 137 and dropped on the first foreign matter transport conveyor 160 to be transferred to the foreign matter collection hopper 152.

In addition, the aggregate having a particle size of 40 mm or more dropped on the first introduction conveyor 170 is supplied to the second crusher 180 through the second hopper 182 and crushed again, and crushed again by the second crusher 180. The aggregate is transported by the second and third discharge conveyors 190 and 200 through the discharge hole of the second crusher 180, and the metal is removed by the metal removing member 210, and the non-ferrous metal is removed by manual operation. Drops on 40 mm metal wire mesh 221 of sorter 220

However, the second sorter 220 has a second driving wheel 230b and a second eccentric shaft fixedly installed on the rotation shaft 230a of the second drive motor 230 to be driven like the first sorter 130. Since the belt 231 is suspended between the second driven wheels 233 installed at the 232, the second driving motor 230 rotates counterclockwise in FIG. 5. The second driving wheel 230b fixed to the rotating shaft 230a rotates counterclockwise in FIG. 5, and the rotational force of the second driving wheel 230b is driven through the belt 231 to the second driven wheel 233. The second driven wheel 233 is rotated in the counterclockwise direction in FIG. 5 so that the first sorter 130 oscillates while drawing an ellipse in the counterclockwise direction so that the aggregate and the foreign matter slide down.

Accordingly, in the crushed construction waste dropped from the third discharge conveyor 210 on the 40 mm metal wire mesh 221 of the second sorter 220, the aggregate having a particle size of 40 mm or less is added to the 40 mm metal wire mesh 221. In the 8 mm metal wire mesh 222 installed below the 40 mm metal wire mesh 221, the powder powder having a particle size of less than 8 mm passes through the 8 mm metal wire mesh 222 to be lowered to the bottom. It is collected in the stone powder collecting hopper 223 is discharged to the stone powder collecting position by the stone powder conveyor 270 through the outlet.

Among the aggregates having a particle size of less than 8 mm to 40 mm that do not pass through the 8 mm metal wire mesh 222, an aggregate having a particle size of less than 8 mm to 25 mm is a 25 mm metal wire mesh 224 installed under the 8 mm metal wire mesh 222. 3) aggregates are collected in the third aggregate collection hopper 225 by passing through the bottom, and the particle size is less than 8mm to less than 25mm by the third aggregate discharge conveyor 231 through the outlet of the third aggregate collection hopper 225. Aggregate that is discharged to an aggregate collection position and has a particle size of less than 25 mm to 40 mm that does not pass through the 25 mm metal wire mesh 134 is collected in the fourth aggregate collection hopper 226 and through the discharge port, a fourth aggregate discharge conveyor. By 290 the particle size is discharged to an aggregate collection location of less than 25 mm to less than 40 mm.

Meanwhile, an aggregate having a particle size of 40 mm or more that does not pass through the 40 mm metal wire mesh 221 of the second sorter 220 falls on the first introduction conveyor 170 according to the fluctuation of the second sorter 130. Since the air discharged through the air discharge pipe 153 and the spouting water discharged through the sprinkling pipe 154 is discharged through the air outlet pipe 155b formed at the right end of the duct 155 of the foreign material sorter 150, the generation of dust At the same time, the foreign matter contained in the aggregate having a particle size of 40 mm or more is blown onto the second foreign matter scattering prevention plate 227 and dropped on the fourth foreign matter conveyance conveyor 230 to be transferred to the foreign matter collection hopper 152. .

In addition, the aggregate having a particle size of 40 mm or more falling on the first introduction conveyor 170 is supplied to the second crusher 180 again through the second hopper 182 and crushed again, and again in the second crusher 180. The crushed aggregate is transported by the second and third discharge conveyors 190 through the discharge hole of the second crusher 180, and the metal is removed again by the metal removing member 210 so that the 40 mm metal of the second sorter 220 is removed. Falling on the wire mesh 221 is reselected by aggregate size as described above.

On the other hand, the foreign matter collected in the foreign matter collection hopper 152 is the rotational driving force of the rotary shaft 301a, the belt 302 and the rotation center of the motor 300 in accordance with the drive of the motor 301 of the foreign matter collector 300 The rotary center shaft 303a is rotated by the shaft 303a, and the blower 303 is rotated to blow air.

Accordingly, when the foreign matter collected by the foreign matter collection hopper 152 is sucked into the cochlear 304 and rotated, the foreign matter falls down and is collected in the storage tank 305, and the blowing air for sucking the foreign matter is stored in the storage tank 305. The air is discharged to the outside through the air outlet 305b, the first air discharge duct 306, the air regulating pad 307, the blower 303, and the shock absorber 309 formed at the center of the center.

At this time, the amount of air discharged to the outside can adjust the opening degree of the air conditioning pad 307 installed between the first air discharge duct 306 and the blower 303 to adjust the discharge of air, including in the exhaust air The discharge rate of the collected dust and air is filtered and buffered by the buffer 309 and then discharged to the outside.

In addition, the foreign matter collected in the storage tank 305 may be shipped by directly loading the discharge port 305a formed in the lower portion of the storage tank 305 to be loaded directly into the loading box of the vehicle 311.

In the above description, the present invention has been described taking as an example earth scald, stone powder, aggregate less than 8 mm, aggregate less than 8 mm to 25 mm, and aggregate less than 25 mm to 40 mm, but the present invention is not limited thereto. As a matter of course, aggregates of different particle sizes can be selected by changing the meshes of the metal wire mesh to different sizes in the first and second sorting machines.

In the above description, the specific embodiments have been shown and described, but the present invention is not limited thereto, for example, by those skilled in the art without departing from the concept of the present invention. Of course, the design can be changed in various ways.

As described above, according to the shredding / selection apparatus of the construction waste according to the present invention, the construction waste which is relatively large in size and included in the construction waste shredded by the first shredder and the long foreign matters is removed, Received through the first shredder and shredded in the construction waste of large and large foreign matters removed construction waste is discharged to the first sorter by the first discharge conveyor, the first sorter 130 is not sorted When aggregate and foreign matter with a particle size of more than a certain size (40 mm or more in size) falls, the foreign matter sorter ejects compressed air and spouting water to sort out foreign matter, and the foreign matter selected by the foreign matter sorter is transferred to the first foreign matter conveying conveyor. Is transferred to the foreign matter collection hopper, and is not separated by the first sorting machine. Transported to the second crusher by the first introduction conveyor to crush the aggregate again, and crushed again, and remove the metal by the metal removing member while transferring the second and third discharge conveyor crushed in the second crusher, When the aggregate is discharged to the second sorter and sorted into various particle sizes, and the aggregates and foreign matters of which the unselected particle size is 40 mm or more fall from the second sorter, the foreign matter sorter presses the compressed air and spout water onto these aggregates and the foreign matter. To sort and transfer to the foreign matter collection hopper by the second foreign matter conveying conveyor, the aggregate size of 40mm or more is dropped on the first introduction conveyor again and fed back to the second crusher through the second hopper, and then crushed again Since the construction wastes are crushed, recycled aggregates and In addition to being able to sort, it is possible not only to lower the manufacturing cost of recycled aggregates, but also to collect and pick up foreign matters directly on a vehicle.
