JP 2009-78265 A

  In the suction wind type sorting device of Patent Document 1, the first and second sorting means are fixedly arranged above and below, the configuration is complicated, and lacks versatility. For example, when the main waste material of the mixed waste thrown into the apparatus is heavy, the first sorting means must be provided very firmly, but in that case, when sorting the mixed waste light in the main waste material, It becomes an excessive structure. In addition, for example, when it is desired to expand the sorting system so that the third and fourth sorting operations are performed before and after the first and second sorting operations, even if a plurality of suction wind type sorting devices are prepared, this cannot be realized. There is sex.

  In addition, when the storage locations of the plurality of types of waste that are selected are separated, it is more convenient to perform the sorting operation of each waste at the storage location (or nearby) of each waste. However, this configuration of the suction wind type sorting device cannot be used freely.

  In addition, although the air blowing means assists the second sorting means to suck air, a sufficient effect may not be obtained depending on the type and configuration of the mixed waste. For example, in the case of mixed waste in which waste materials such as paper waste and solid matter are mixed, since paper waste and solid matter may be entangled, only relatively light paper waste will be levitated toward the second sorting means. Even so, there is a possibility that the paper waste will not be separated well only by the air adjustment of the air blowing means.

  In addition, the wind force adjusting unit that works to separate the waste transferred by the mesh conveyor from the winding belt is less effective when the weight of the waste is light. The present invention has been made in view of the above-mentioned background art, and can provide a wind power sorting device that can freely configure a sorting system suitable for various mixed waste forms and that can efficiently and reliably sort. The purpose is to do.

  In this device, the first conveyor for transporting the mixed waste placed on the transfer surface and the upper and lower surfaces of the endless belt having a large number of air holes reciprocate, and the lower surface is the first conveyor. A second conveyor disposed facing the upper side of the transfer surface of the conveyor, and provided between the lower side surface and the upper side surface of the second conveyor, on the transfer surface of the first conveyor An air suction device for sucking a specific waste existing on the lower side by air suction, and the waste adsorbed on the lower side provided between the lower side and the upper side of the second conveyor A first air blowing device that blows out air that forcibly drops, and a specific waste that is disposed above the transfer surface of the first conveyor and moves on the transfer surface on the lower surface of the second conveyor The scraping rotating body Example was a wind sorting device.

  Furthermore, it is provided in the vicinity of the transfer surface of the first conveyor, and includes a second air blowing device for blowing out air for levitating specific waste moving on the transfer surface toward the lower surface of the second conveyor. Yes.

  The wind power sorter of the present invention can selectively collect the predetermined waste contained in the mixed waste on the first conveyor on the second conveyor and efficiently recover it, and realizes its function with a simple configuration. Is. In addition, by adjusting the length and installation direction of each conveyor, waste can be freely transferred from the place where the mixed waste is put to the individual stock yard of the sorted waste regardless of its location and distance. it can.

  Furthermore, the waste transported by the second conveyor can be reliably removed from the endless belt by the operation of the first air blowing device. In addition, a scraping rotating body and a second air blowing device are provided in the vicinity of the transfer surface of the first conveyor, and the operation of the air suction device is assisted by levitating the waste to be sorted and collected toward the lower surface side of the second conveyor. Thus, sorting and collection can be performed reliably.

  In addition, a plurality of second conveyors, etc. are provided for one first conveyor, waste that is transferred and dropped by the second conveyor is received by a new first conveyor, and a new second conveyor is provided. Or you may. In this way, by changing and expanding the combination of the devices, an optimal sorting system can be freely configured according to various mixed waste modes.

  Hereinafter, a wind power sorting apparatus 10 according to an embodiment of the present invention will be described with reference to the drawings. The wind power sorter 10 receives a mixed waste W mixed with a plurality of types of waste materials, sorts a relatively light waste W1 such as plastic or paper, and collects it in the stock yard 12, and other relatively heavy wastes. This is a device for collecting the item W2 in the stockyard 14.

  As shown in FIG. 1, the wind sorting apparatus 10 includes a first conveyor 16 for horizontal conveyance having a transfer surface 18 that is elongated in the transfer direction. Here, the first conveyor 16 is a general belt conveyor or the like, and the right end in FIG. 1 is the carry-in end 18a into which the mixed waste W is charged, and the left end is the waste W2 transferred. It is the discharge end 18b which discharges.

  A second conveyor 20 is provided in the center of the first conveyor in the transfer direction and slightly closer to the discharge end 18b. As shown in FIGS. 2 and 3, the second conveyor 20 has an endless belt 24, which forms a transfer surface having a large number of air holes, stretched between a pair of sprockets 22a and 22b. Driven by rotation. Here, as the endless belt 24, a mesh conveyor belt in which a mesh-like transfer surface is formed using a metal net, a thin metal member, or the like is used. The second conveyor 20 is arranged above the first conveyor 16 so as to intersect the transfer direction of the first conveyor 16, and the transfer surface 18 of the first conveyor 16 and the lower surface 24 a of the endless belt 24 of the second conveyor 20, Are facing up and down. The sprocket 22a, which is the starting end of the lower side surface 24a, is disposed at a position slightly outside the one end in the width direction of the first conveyor, and the sprocket 22b, which is the terminal end of the lower side surface 24a, is the other end in the width direction of the first conveyor. It is arranged at a position sufficiently outside from one end.

  A blower 26 driven by a motor 26 a is provided on the side of the second conveyor 20. The blower 26 becomes a wind source for air suction or air blowing by circulating air through a plurality of ducts 30, 34, and 38, which will be described later. In addition, the motor 26a and the air blower 26 which are shown in a figure may be installed a little away from the 1st conveyor 16 and the 2nd conveyor 20 on line structure.

  Between the lower side surface 24a and the upper side surface 24b of the second conveyor 20, the mixed waste W on the transfer surface 18 of the first conveyor 16 is sucked in air, and the waste W1 is adsorbed on the lower side surface 24a. An air suction device is provided. As shown in FIGS. 2 and 3, the air suction device has a suction hood 28 that is a substantially rectangular box having an opening on the lower surface 24 a side, and is connected via a duct 30 for air piping. Connected to the blower 26. The suction hood 28 is substantially equal in width to the lower side surface 24a, has a length of about ¾ of the length of the lower side surface 24a, and covers a wide area near the sprocket 22a that is the starting end of the lower side surface 24a. The duct 30 is connected to a suction port 28a opened on the side surface of the suction hood 28, and air in the suction hood 28 is sucked by the blower 26. The strength of the air suction can be controlled by adjusting the output of the blower 26 by wind force adjusting means (not shown).

  A first air blowing device that blows out air forcibly dropping off the waste W1 adsorbed on the lower side surface 24a at a position between the sprocket 22b that is the terminal end of the lower side surface 24a of the second conveyor 20 and the suction hood 28. Is provided. 2 and 3, the first air blowing device is a first blowing nozzle 32 that blows air downward toward the lower side 24a, and is connected to the blower 26 through a duct 34 for air piping. ing. The outlet of the first outlet nozzle 32 opens so as to blow out air widely in the width direction of the lower side surface 24a. The duct 34 is connected to the rear end portion of the first blowing nozzle 32 and has a structure in which air is sent from the blower 26 toward the first blowing nozzle 32. The strength of the air blowing can be adjusted by wind force adjusting means (not shown).

  As shown in FIGS. 4 and 5, the waste W1 moving on the transfer surface 18 is second above the transfer surface 18 of the first conveyor 16 and on the side of the discharge end 18b of the second conveyor 20. A scraping rotating body 35 for scraping up toward the lower surface 24 of the conveyor 20 is provided. The scraping rotary body 35 has a rotation shaft that is as long as the width of the transfer surface 18, and a roll brush in which a wire brush is implanted on the surface of the rotation shaft, and a plurality of scraping plates on the surface of the rotation shaft. The thing of the form erected at equal intervals radially is suitable. The scraping rotator 35 is disposed above the transfer surface 18 in a direction perpendicular to the transfer direction of the mixed waste W, and rotates below the second conveyor 20 by rotating counterclockwise as shown in FIG. The lightweight waste W1 is scraped up, transferred in the direction of the lower surface 24, and then floated.

  In the vicinity of the first conveyor 16, a pair of second air blowing devices for supplying air for causing the waste W <b> 1 moving on the transfer surface 18 to float toward the lower surface side 24 are provided. As shown in FIGS. 2 and 3, the second air blowing device is a pair of second blowing nozzles 36 that are arranged on the left and right sides of the transfer surface 18 and blows air toward the lower side 24a. It is connected to the blower 26 through a duct 38 for air piping. The duct 38 is connected to the rear end portion of the second blowing nozzle 36 and has a structure in which air is sent from the blower 26 toward the second blowing nozzle 36. The direction and strength of the air blowing can be adjusted by adjusting means (not shown).

  As shown in FIG. 1, stock yards 12 and 14 for collecting wastes W1 and W2, respectively, are provided under the floor where the wind sorting apparatus 10 is installed, and the stock yards 12 are provided below the first blowing nozzle 32. The charging port 12a is opened, and the charging port 14a to the stock yard 14 is opened below the discharge end 18b of the first conveyor 16.

Next, the operation of the wind power sorting apparatus 10 will be described. First, the mixed waste W generated at a general factory or construction site is thrown into the carry-in end 18 a of the first conveyor 16. The mixed waste W moves on the transfer surface 18 and tries to pass below the second conveyor 20.

  Then, an air suction force of a predetermined strength that is intended to be drawn into the suction hood 28 acts on the entire mixed waste W, and only the waste W1 such as lightweight plastic and paper contained in the mixed waste W is obtained. It floats and is attracted to the lower surface 24a of the second conveyor 20. At this time, although the transfer surface 18 of the first conveyor is covered in the width direction by the suction hood 28, the suction force to the waste W1 existing at the end portion in the width direction of the transfer surface 18 is slightly weakened. However, the air blown by the second blowing nozzles 36 on the left and right sides of the first conveyor 16 is received, and the waste W1 existing at the end portion can also be lifted and adsorbed to the lower side surface 24a of the second conveyor 20.

The waste W1 entangled with the relatively heavy waste W2 remains on the transfer surface 18 of the first conveyor 16 and passes below the conveyor 20 even if it receives air suction from the suction hood 28. However, it is separated from the waste W2 by being scraped up by the subsequent scraping rotary body 35, transferred to the lower side surface 24a of the second conveyor 20, lifted, and subjected to the action of the air suction force, the lower side surface 24a. The waste W1 adsorbed on the lower surface 24a of the endless belt 24 of the second conveyor 20 is transferred to the sprocket 22b side. When the waste W1 comes to a position outside the suction hood 28, the air suction force is lost and this time the air blown downward from the first blow nozzle 32 is received, so that the waste W1 is forcibly separated from the lower side surface 24a. It is made to fall down. Then, the dropped waste W1 is collected in the stock yard 12 through the inlet 12a.

  On the other hand, the relatively heavy waste W2 remains on the transfer surface 18 of the first conveyor 16 even if it is scraped up by the scraping rotator 35 and is transported as it is toward the unloading end 18b. The waste W2 that has reached the carry-out end 18b and dropped downward is collected into the stock yard 14 from the input port 14a.

  As described above, the wind power sorting device 10 can selectively adsorb the lightweight waste W1 contained in the mixed waste W on the first conveyor 16 to the second conveyor 20 and efficiently collect the waste W1, Functions can be realized with a simple configuration. If the length and installation direction of the first and second conveyors 16 and 20 are adjusted, it is possible to easily cope with a change in the stock yard which is a storage place for the wastes W1 and W2. By the operation of the first blowing nozzle 32, the waste W1 transferred by the second conveyor 20 can be surely dropped from the lower side surface 24a, and the left and right sides of the first conveyor 16 where the waste W1 does not remain on the endless belt 24. The second blowout nozzle 36 is provided on the second conveyor 20, and the waste W1 is floated toward the lower surface 24a of the second conveyor 20, so that the waste W1 that has passed under the second conveyor 20 is further lifted up. By transporting and floating toward the lower surface side 24a of the air 20, the air suction toward the suction hood 28 can be assisted, and the waste W1 can be selectively collected.

  Note that the wind power sorting apparatus of the present invention is not limited to the above embodiment. For example, the form of the suction hood 28 that is an air suction device may be configured such that a plurality of small suction hoods are arranged and the lower surface of the second conveyor is covered as a whole so as to suck air. In that case, if the suction force of the suction hood arranged at the end portion in the width direction of the transfer surface of the first conveyor is set slightly stronger, the second air blowing device can be deleted. Alternatively, the duct 30 and the large blower 26 may be omitted, and a dedicated air generator corresponding to the blower 26 may be provided integrally with the suction hood 28.

  As for the 1st blowing nozzle 32 which is a 1st air blowing apparatus, you may arrange several blowing nozzles of a small blowing outlet in the width direction of the lower surface 24a of the 2nd conveyor 20. As shown in FIG. Similarly, with respect to the pair of second blowing nozzles 36 that are the second air blowing devices, a plurality of blowing nozzles with small outlets may be arranged in the transfer direction of the first conveyor 16. Further, the first air blowing device and the second air blowing device may be provided separately from the air generating device for suction. The ducts 34 and 38 and the large blower 26 may be omitted, and a dedicated air generator corresponding to the blower 26 may be provided separately from the first and second blowing nozzles 32 and 36.

  The scraping rotary body 35 may have a plurality of small ones having a short rotation axis in the width direction of the transfer surface 18 of the first conveyor 16. Moreover, you may arrange | position not the side of the 2nd conveyor 20, but the downward direction. In addition, the positions of the scraping rotary body 35, the suction hood 28, and the suction duct 30 may be reversed.

  As for the arrangement of the conveyors, a plurality of second conveyors may be provided for one first conveyor. For example, in FIG. 1, by providing a new second conveyor or the like above the stock yard 40, a wind power sorting device that sorts and collects waste that is smaller and lighter than the waste W1 in the stock yard 40 is configured. Can do. It is also possible to adopt a configuration in which the waste collected by the second conveyor and dropped off from the lower surface is received by a new first conveyor, and further a new second conveyor or the like is provided for re-sorting. In this way, by changing / expanding the combination of each device, it is possible to freely configure an optimum sorting system in accordance with various mixed waste forms.
