  The device of Patent Document 3 has a structure suitable for separating relatively light objects, both hard plastic and plastic film, and even if a fine granular material is collected together with the film. There is a problem that the film and the granular material cannot be separated.

  Moreover, although the said conventional apparatus is an apparatus using the conveyor belt with a flat transfer surface, it is U type (trough type) used, for example when transferring heavy crushed materials, such as a concrete crushed material. A conveyor device using a conveyor belt has a problem that it is difficult to apply any of the conventional devices.

  The present invention has been made in view of the problems of the above-described conventional devices, and can be applied to a conveyor device that conveys a relatively heavy crushed material such as debris and crushed stone, and includes debris and crushed stone. An object of the present invention is to provide a wind power sorting device capable of efficiently separating crushed materials in mixed waste materials and light-weight foreign matters such as plastics and wood chips.

  It is another object of the present invention to provide a wind power sorting apparatus that can further separately collect plastic, wood chips, and the like as foreign substances separated as lightweight objects and particulates such as concrete powder that can be a product.

  It is another object of the present invention to provide a wind power sorting device that can be applied even to a U-shaped (trough type) conveyor device capable of transporting crushed material having a relatively large weight.

  Another object of the present invention is to provide a wind power sorting device that can be easily applied to an existing conveyor device.

In order to achieve the above object, the present invention
First , in order to separate a mixture of heavy and light items on a conveyor belt, a blowing nozzle for blowing air in a direction orthogonal to the traveling direction of the conveyor belt is provided on the upper surface of the conveyor belt, A light-weight object inlet is formed on the opposite side of the conveyor belt facing the direction, and a vibration imparting roller whose rotation center axis is parallel to the blowing direction is installed on the back side of the conveyor belt. The conveyor belt in the air blowing area of the air blowing nozzle is reciprocally oscillated in the up and down direction by providing a chute that extends downward and communicates with the charging port. A branch part that branches into a chute part and a second chute part is provided, a partition net is provided at the upper end part of the second chute part, and the above-mentioned partition net is among the falling lightweight objects A first lightweight object that cannot pass is guided to the first chute part, and a second lightweight object that can pass through the partition net is dropped to the second chute part, and the first chute part and the second chute part are configured to drop. der those connecting each first and second light product collection boxes is, the second blowing nozzle capable of blowing air in the direction of the partition net to the side of the chute is provided at each lower end of the chute, fall The second lightweight object is configured to be guided in the second chute by passing through the partition by blowing off in the direction of the partition by blowing from the second blowing nozzle, and A guide plate extending in the direction of the inside of the chute and in the direction of the partition net is provided on the side surface of the chute on the upstream side of the second air blowing nozzle, and a space is provided between the leading end of the guide plate and the partition net. Forming and falling The second lightweight object is configured such that the second lightweight object can be guided into the second chute portion by contacting the second lightweight object with the guide plate and reflecting in the direction of the partition net, and the first lightweight object. Is constituted by a wind power sorting device that is configured to be able to fall in the direction of the first chute portion through the space .

It is preferable that the partition net is provided to be inclined in the direction of the first chute portion. The said ventilation area means the area on the conveyor ventilated from a ventilation nozzle, for example, the ventilation area (T) from a ventilation nozzle (8). The first lightweight object refers to a relatively large lightweight object that cannot pass through a partition network such as plastic and wood. The said 2nd lightweight material says the granular material which can pass through a partition network like the concrete powder etc. which are contained in the crushed concrete crushed material, for example. When configured in this way, for example, debris and crushed stones including heavy objects such as concrete lumps and lightweight materials such as plastic and granular materials are conveyed by the conveyor belt, and when reaching the air blowing area, the conveyor belt is caused by vertical reciprocating vibration. , Debris, crushed stones, etc. float above the conveyor belt, and heavy and lightweight materials separate in the air, so at the reciprocating vibration position, the air is blown in the direction perpendicular to the conveyor belt traveling direction. Only an object can be blown away in a direction orthogonal to the direction of travel of the conveyor, with the object directed toward the input port. A heavy article such as a concrete lump that is a product (for example, a heavy lump such as a concrete lump under 40 mm in diameter) is directly conveyed upstream by a conveyor belt. Lightweight items that have been thrown into the inlet are lightened (such as concrete powder) that are not able to pass through the partition net at the branching portion (light plastics, wood chips, etc.) that are guided through the first chute. The granular material) falls to the second chute portion, and finally, the light-weight material such as plastic and wood pieces as foreign matter is collected in the first light-weight material collection box, and the granular material such as concrete powder (for example, a product) Concrete powder having a diameter of about 5 mm or less) can be collected in the second lightweight collection box. In this way, lightweight materials can be selectively removed from debris, crushed stones, etc., and the lightweight materials can be used as foreign materials (dust), for example, relatively large lightweight foreign materials such as plastic and wood chips, and finally as products. It can be collected separately into granular lightweight objects such as concrete powder returned to the place where the concrete block is collected. Among the lightweight objects that have dropped the chute, when granular materials such as concrete powder that should be transferred to the second chute part have dropped in the direction of the first chute part, the granular material is blown from the second blowing nozzle. Thus, it can be blown away in the direction of the partition net, and the particulate matter can be guided in the direction of the second chute portion. Thereby, more accurate classification can be performed. Therefore, it is possible to more accurately separate a relatively large lightweight object (first lightweight object) as a foreign substance and a granular lightweight object (second lightweight object) such as concrete powder returned to the product. Among the lightweight objects that have dropped the chute, if the granular material such as concrete powder that should be transferred to the second chute part has dropped in the direction of the first chute part, this granular substance is brought into contact with the guide plate. Since the first lightweight object that can be reflected in the direction of the partitioning net and cannot pass through the partitioning net can pass through the space and fall in the direction of the first chute portion, more accurate separation can be performed. it can. It is possible to reflect and guide the particulate matter such as sand that comes into contact with the guide plate in the direction of the partitioning net, and the particulate matter that has passed through the space can be further blown off in the direction of the partitioning net by blowing from the second blowing nozzle. Thus, it is possible to more accurately separate a relatively large lightweight object from a granular lightweight object such as concrete powder.

It is configured to be able to proceed in a curved state (trough type) in a U-shape by standing upright. Thereby, without dropping heavy objects such as a concrete lump as building waste from both side edges of the conveyor belt 2, it can be smoothly conveyed in the vicinity of the center of the conveyor belt 2.

  In the conveyor device 1, the raw material supplied on the conveyor belt 2 on the upstream end side thereof is first or secondarily crushed from a construction waste material through a vibration sieve by a crusher such as an impact crusher. Heavy crushed materials such as concrete blocks with a diameter of 40 mm or less as products, plastics (including plastic films, etc.), wood chips (including other papers, etc.), concrete powder, etc. Mixed waste materials (such as debris and crushed stones) that contain light-weight materials composed of other dust and the like (eg, concrete particles having a diameter of about 5 mm or less to several millimeters), such debris and crushed stones, etc. Is conveyed in the direction of arrow A. And in the middle of the path | route of the said conveyor apparatus 1 (installation area E of FIG. 1, FIG. 4), the wind power sorter 6 which concerns on this invention is installed.

  Therefore, while conveying the mixed waste material such as the crushed material on the conveyor belt 2, the wind power sorting device 6 selects and removes lightweight materials such as the plastic, wood chips, and concrete powder from the mixed waste material.

  Moreover, in the said conveyor apparatus 1, the predetermined area (installation area E in FIG. 1, FIG. 4) enclosed by the carrier rollers 4-3 and 4-4 is specified as an area which installs the said wind-power sorter 6, and the said installation In the upstream and downstream carrier rollers 4-3 and 4-4 closest to the area E, the horizontal rollers 4 b and 4 b and the left side (inlet 22 side) inclined rollers 4 a ′ and 4 a ′ are raised angles. 31 and 31 and the support angles 7 and 7 are removed, and one standing angle 31 and the support angle 7 are also removed (see FIGS. 4 and 7B). That is, at least the inclined rollers 4a 'and 4a' on the inlet 22 side among the carrier rollers 4-3 and 4-4 on the upstream side and the downstream side across the air blowing area T (see FIG. 4) of the conveyor belt 2, The central rollers 4b and 4b are removed.

  Here, in the carrier rollers 4-3 and 4-4, the inclined rollers remaining after the inclined rollers 4a ′ and 4a ′ and the horizontal rollers 4b and 4b are removed are denoted by reference numerals 4A and 4A (FIG. 1, see FIG. In the carrier rollers 4-3 and 4-4, the carrier rollers 4a 'and 4a' may be removed and the horizontal rollers 4b and 4b may be left.

  When the inclined rollers 4a 'and 4a' and the horizontal rollers 4b and 4b of the carrier rollers 4-3 and 4-4 are removed in this way, the traveling direction in the area E (the direction of the arrow A) in the trough conveyor belt 2 ), The belt on the right side maintains the rising surface 2a in a state of rising obliquely to the right side by the inclined rollers 4A and 4A (see FIGS. 6A and 6B). The belt on the left side with respect to the direction (the direction of arrow A) gradually becomes horizontal after passing the carrier roller 4-2 that is one upstream of the carrier roller 4-3. In the range of the installation area E up to -4, a horizontal plane 2a ′ that is inclined upward with respect to the direction of travel of the conveyor belt is formed (see FIGS. 6A and 6B).

  Then, the horizontal surface 2a ′ gradually rises to the inclined state after passing the carrier roller 4-4, and on the upstream side from the carrier roller 4-5, the inclined roller 4a ′ returns to the rising surface, On the downstream side after the carrier roller 4-5, the trough type conveyor belt 2 is restored.

  The wind power sorting apparatus 6 according to the present invention is installed in an installation area E in which a horizontal plane 2a ′ is formed on the left side of the conveyor belt 2 between the carrier rollers 4-3 and 4-4 (between the inclined rollers 4A and 4A). Installed.

  Between the inclined rollers 4A and 4A, the blower nozzle 8 is fixed to the machine frame 3 on the right side with respect to the traveling direction (arrow A direction) of the conveyor device 1 in a direction orthogonal to the traveling direction of the conveyor belt 2. . As shown in FIG. 11, the blower nozzle 8 includes a cylindrical tube portion 8a and a nozzle portion 8b connected to the tube portion 8a. The nozzle portion 8a includes the tube portion 8a and the nozzle portion 8a. The rectangular connecting portion 8a 'is widened in the horizontal direction (lateral direction), and is further reduced in the vertical direction from the rectangular connecting portion 8a', whereby the blower outlet 8b 'elongated in the horizontal direction (lateral direction). (The width of the outlet 8b 'is defined as T).

  Then, as shown in FIG. 1, a pair of brackets 9 and 9 are horizontally projected on the downstream side and the upstream side of the longitudinal upper collar 3a of the right machine casing 3, and supported by these brackets 9 and 9. Angles 10 and 10 are erected in a direction perpendicular to the upper collar 3a, and a connecting gavel 11 is fixed in parallel to the upper collar 3a between the supporting angles 10 and 10, and the U-shaped The tube portion 8 a of the blower nozzle 8 is fixed with the shape mounting angle 12. As shown in FIG. 1, the blower nozzle 8 is parallel to the conveyor traveling direction so that the horizontally long outlet 8b 'is parallel to the right edge (the upright surface 2a) of the uphill inclined conveyor belt 2. Fix in an uphill state.

  As shown in FIGS. 4 and 5, the air outlet 8 b ′ of the blower nozzle 8 is directed from the rising surface 2 a side of the conveyor belt 2 in a direction orthogonal to the traveling direction of the conveyor belt 2, and the air outlet 8 b ′. The air can be blown out in a direction perpendicular to the traveling direction of the conveyor belt 2.

  Although the attachment position and attachment angle of the blower nozzle 8 are arbitrary, the outlet 8b 'is located in the vicinity of the upper edge of the upright surface 2a in the upward inclined state of the conveyor belt 2, and the outlet 8b' is It is preferable to fix in an upward inclined state so as to be parallel to the upper edge.

  Further, in FIG. 5, the blow nozzle 8 is fixed so that air is blown out in parallel to the horizontal surface 2a 'of the conveyor belt 2 (in the direction of arrow C), but as shown by a two-dot chain line in FIG. Further, in the left-right direction of the conveyor belt 2, the air outlet 8 b ′ may be slightly downward and the pipe portion 8 a side may be raised so that air is blown out in parallel with the upright surface 2 a. In any case, it is fixed at an appropriate position according to the properties of the crushed material and the lightweight material to be conveyed.

  In FIG. 1, a pair of brackets 13 and 13 are fixed to the upper arm 3 a on the right side of the machine casing 3 on the upstream side of the installation area E, and a gate-shaped support angle 14 is vertically mounted on the brackets 13 and 13. The blower 15 is fixed on the support angle 14. Then, a flexible duct (blower pipe) 16 is connected between the blower opening of the blower 15 and the pipe portion 8 a of the blower nozzle 8 so that the blower 15 can blow air to the blower nozzle 8. An air volume adjustment damper 17 is provided in the middle of the duct 16 to adjust the air volume blown from the blowing nozzle 8.

  Therefore, as shown in FIG. 4, the horizontal surface of the conveyor belt 2 extends from the outlet 8 b ′ of the blower nozzle 8 to substantially the width T on the surface of the conveyor belt 2 corresponding to the width T of the outlet 8 b ′. Air can be jetted in a direction orthogonal to the traveling direction of the conveyor belt 2 substantially parallel to 2a ′. Here, a range on the conveyor belt 2 that is a range in which air is blown from the air outlet 8b 'is referred to as a blowing area T.

  On the back side of the conveyor belt 2 in the installation area E, a vibration applying roller 18 is provided at the center position between the inclined rollers 4A and 4A (see FIG. 4). As shown in FIG. 5, the vibration applying roller 18 fixes bearings 19 and 19 on installation bases 48 and 48 fixed on the left and right upper rods 3 a and 3 a of the machine frame 3. The roller 19 is installed on the back side of the conveyor belt 2 by rotatably supporting the rotation center shaft 18a of the roller 18 on the bearings 19, 19. The vibration applying roller 18 is pivotally supported such that the rotation center shaft 18 a is parallel to the blowing direction of the blowing nozzle 8. Further, the vibration applying roller 18 is pivotally supported on the back surface side of the conveyor belt 2 so as to vibrate the conveyor belt 2 in the air blowing area T in the vertical direction.

  As shown in FIG. 8, the roller portion 18b of the vibration applying roller 18 has an elliptical cross section as a whole, and is configured by an elliptical cylinder as a whole. It is comprised so that the horizontal part 2a 'back surface may contact (refer FIG. 1, FIG. 5).

  A driving pulley 20 is fixed to one rotation center shaft 18a of the vibration applying roller 18. The pulley 20 and an output shaft pulley of a driving motor 21 fixed on the right upper rod 3a. An endless belt 38 is stretched between the belt 21a (see FIG. 1). Therefore, when the drive motor 21 is rotationally driven, the vibration applying roller 18 is rotationally driven via the endless belt 38 and the pulley 20, and an elliptical long diameter portion d with respect to the rotation center axis 18 a on the outer peripheral surface of the roller 18. And the short-diameter portion d ′ (see FIG. 8B) alternately contact the back surface of the horizontal surface 2a ′ of the conveyor belt 2, thereby substantially reducing the horizontal surface 2a ′ of the belt 2 in the installation area E. The vicinity of the central portion N (inside the blowing area T) (see FIG. 4) can be reciprocally oscillated in the vertical direction (directions of arrows F and L) (see the two-dot chain line of the conveyor belt 2 in FIG. 5).

  Due to the up and down reciprocating vibration of the horizontal surface 2a 'of the conveyor belt 2, light weight materials (light weight foreign matters such as plastic and wood pieces, and granular materials such as concrete powder) in the conveyed mixed waste material are lifted or on the light weight materials. Since the crushed material (heavy material) is detached from the light material in the vertical direction or the like, the light material can be blown away in the direction orthogonal to the traveling direction of the conveyor device 1 with the blast air from the blower nozzle 8.

  Here, as shown in FIG. 4, it is preferable to inject air from the blow nozzle 8 along the central axis direction of the vibration applying roller 18, and in the lateral direction of the outlet 8 b ′ of the blow nozzle 8. By disposing the vibration applying roller 18 within the range of the width T (within the range of the blower area T), it is possible to efficiently blow off (select) a lightweight object by the single vibration applying roller 18.

  The number of rotations of the vibration applying roller 18 is controlled by controlling the number of rotations of the drive motor 21 with an inverter or the like, so that the properties such as debris, crushed stones, weight, and the like including a light object (light foreign matter) to be conveyed are controlled. Accordingly, the frequency of the vertical vibration of the conveyor belt 2 can be adjusted. For example, by increasing the rotation speed of the vibration applying roller 18, the vibration frequency of the conveyor belt 2 in the vertical direction can be increased.

  Further, the amplitude of vibration in the vertical direction of the conveyor belt 2 can be changed by changing the elliptical diameter (the length of the long diameter portion d and the short diameter portion d ′) of the roller portion 18 b of the vibration applying roller 18. it can. For example, by making the long diameter portion d of the roller portion 18b of the vibration applying roller 18 longer than the short diameter portion d ', the amplitude of the vertical vibration of the conveyor belt 2 can be increased. Thereby, the amplitude of the vibration in the vertical direction of the conveyor belt 2 can be adjusted to an optimum state according to properties such as debris, crushed stones, and the like including weights (light foreign matters) to be conveyed and properties such as weight. it can. Of course, the frequency and amplitude of the vertical vibration of the conveyor belt 2 can be adjusted by simultaneously adjusting the rotation speed of the drive motor 21 and the diameter of the vibration applying roller 18.

  Further, depending on the properties of debris, crushed stones and the like that are conveyed, the conveyor belt 2 may not be vibrated. Accordingly, a clutch may be provided in the drive motor 21 of the vibration applying roller 18 so that the drive motor 21 is idled and the rotation of the vibration applying roller 18 can be stopped.

  Further, a vertical height adjustment mechanism is provided on the left and right installation bases 48 of the vibration applying roller 18, and the roller portion 18b of the vibration applying roller 18 is normally in contact with the back surface of the conveyor belt 2. When the conveyor belt 2 is not vibrated, the height of the vibration applying roller 18 is lowered by the height adjusting mechanism, thereby separating the roller portion 18b from the back surface of the conveyor belt 2, It can also be set so that the conveyor belt 2 does not vibrate. The height adjusting mechanism is provided with, for example, an L-shaped angle that supports the bearings 19, 19 on the installation bases 48, 48 so as to be slidable in the vertical direction, and the L-shaped angle is provided at several positions in the vertical direction. It can be configured to be locked with a lock pin or the like.

  As shown in FIG. 2, on the opposite side of the air blowing nozzle 8 across the conveyor belt 2 in the installation area E, for receiving the light foreign matter and particulates blown off by the air blowing from the air blowing nozzle 8.

It is reflected in the direction of the second chute portion 27 (partition net 41) (in the direction of arrow I) to prevent the particulate matter from falling on the first chute portion 26. Incidentally, lightweight foreign matters such as plastics and wood pieces pass through the space S and fall in the direction of arrow J (the first chute portion 26 direction) in FIG.

  A second blower nozzle 43 is installed on the right side surface 26 b of the first chute portion 26. As shown in FIG. 12, the blower nozzle 43 includes a cylindrical tube portion 43a and a nozzle portion 43b connected to the tube portion 43a. The nozzle portion 43a includes the tube portion 43a and the nozzle portion 43a. The rectangular connecting portion 43a ′ is expanded in the horizontal direction and is further reduced in the vertical direction from the rectangular connecting portion 43a ′ to the pipe portion 43a, whereby the horizontally elongated air outlet 43b ′ (width T ′). ) Is formed.

  The outlet 43b ′ is formed with a fixing flange 44 for installation on the right side surface 26b of the first chute portion 26. The flange 44 is used to attach the right side surface 26b to the right side surface 26b. It is fixed (see FIG. 2). A horizontal elongated slit 45 corresponding to the outlet 43b 'is formed on the right side surface 26b (see FIG. 13). The width T ′ of the slit 45 corresponds to the width of the air outlet 43b ′, which is slightly shorter than the lateral width of the right side surface 26b of the first chute portion 26, but is open over substantially the entire right side surface 26b. Has been. And the blower outlet 43b 'of the said ventilation nozzle 43 is addressed to the said slit 45, and the said flange 44 and the said side surface 26b are connected and fixed with a volt | bolt.

  The fixed angle of the blower nozzle 43 is configured such that the central axis of the pipe portion 43a, that is, the air blowing direction (arrow K direction) is perpendicular to the partitioning net 41 (direction of the partitioning net 41). (See FIG. 2). Then, a flexible duct (blower pipe) 46 for chute is branched from a part of the flexible duct 16 of the blower 15, the tip of the flexible duct 46 is connected to the pipe part 43 a of the blower duct 43, and It is comprised so that the air from the air blower 15 can be injected from the blower outlet 43b 'of the said air blow duct 43. FIG.

  The air from the outlet 43b ′ is configured to be able to be jetted in a direction orthogonal to the partition net 41 over the width T ′, and from the space S toward the first chute portion 26. It has a function to blow off particulates such as falling sand in the direction of the second chute portion 27.

  As described above, in the branching portion 25, the guide plate 42 is disposed on the upstream side and the second air duct 43 is disposed on the downstream side with respect to the falling direction of the lightweight object. Thereby, the particulate matter such as concrete powder contacting the guide plate 42 can be reflected and guided in the direction of the partitioning net 41, and further the particulate matter that has passed through the space S is blown from the second blowing nozzle 43 by the blowing air. It is possible to blow away in the direction of 41, and it is possible to very accurately separate a relatively large lightweight object (light foreign matter) and a granular lightweight object such as concrete powder. In FIG. 1, 49 is an air volume adjusting damper of the flexible duct 46, and 50 in FIG.

  The air volume of the blowing nozzle 8 and the second blowing nozzle 43 of the present invention can be adjusted by the air volume adjusting dampers 17 and 49, respectively. This air volume can be adjusted according to the properties of the object to be transported (types, sizes, etc. of the transported object and the lightweight object). For example, when there are many pieces of wood having a relatively large weight as a lightweight foreign object, adjustment such as increasing the air volume of the blower nozzle 8 can be performed.

  Further, by adjusting the air volume adjusting dampers 17 and 49, the balance between the air volume blown from the blower nozzle 8 and the air volume blown from the second blower nozzle 43 can be adjusted independently. Depending on the type of the lightweight object, etc., the air volume of the air blowing nozzle 8 and the second air blowing nozzle 43 can be set to an optimum balance to perform the selecting operation. In addition, the air volume of the blower 15 itself can be controlled by controlling the rotation speed of the drive motor of the blower 15 with an inverter or the like.

  Since this invention is comprised as mentioned above, the operation | movement of the wind sorting apparatus which concerns on the following this invention is demonstrated.

  First, the conveyor belt 2 is driven to rotate, and the drive motor 21 is driven to rotate the vibration applying roller 18 so that the horizontal surface 2a ′ of the conveyor belt 2 in the installation area E (air blowing area T) reciprocates in the vertical direction. It shall be. At the same time, it is assumed that the blower 15 is driven so that air is jetted in the direction of arrow C from the blower nozzle 8 (see FIG. 5) and air is jetted in the direction of arrow K from the second blower nozzle 43.

  In this state, a relatively heavy concrete lump, crushed stone, etc. (for example, about 40 mm to 10 mm in diameter) as a product having a diameter of 40 mm or less that is secondarily crushed from building waste by the conveyor belt 2, and building as a foreign object Debris, crushed stones, etc., including plastics, wastes such as wood chips (light foreign matter), and wastes that are finally returned as products, such as concrete, such as concrete powder with a diameter of about 5 mm or less It is assumed that mixed waste material) is being transported.

  These debris, crushed stones and the like are smoothly transported from the upstream side to the downstream side by the trough-type conveyor belt 2, and are conveyed by the guide plate 40 from the front side of the installation area E and past the carrier roller 4-2. It is guided near the center of the belt 2 and enters the wind power sorting device 6 (the shielding box portion 33) from the inlet 36 of the wind power sorting device 6.

  The mixed waste material that has entered the shielding box 33 passes through the horizontal plane 2a ′ of the conveyor belt 2 and exits from the shielding box 33 through the outlet 37. The horizontal plane 2a ′ is rotated by the rotation of the vibration applying roller 18. Because of the reciprocating vibration in the vertical direction, the relatively heavy concrete blocks, which are mixed waste materials that pass through the horizontal surface 2a ', and the crushed materials such as stone blocks and crushed stones are repeatedly lifted upward and dropped downward. In addition, lightweight materials such as plastics and wood chips (light foreign matter) and lightweight materials such as concrete grains contained in the mixed waste material are similarly lifted upward and repeatedly dropped downward.

  Therefore, the heavy crushed material and the lightweight material are separated from each other in the air while passing through the horizontal surface 2a 'of the conveyor belt 2 that reciprocally vibrates. Therefore, the lightweight object floating in the air by the jet air in the direction (arrow C direction) orthogonal to the direction of travel of the conveyor belt 2 moves in the air jet direction (arrow C direction), that is, the direction of travel of the conveyor belt 2. In the orthogonal direction, it is easily blown off in the direction of the chute 23 (in the direction of the charging port 22) on the horizontal plane 2a ', and is charged into the chute 23 from the charging port 22 at the opposite position.

  At this time, since the insertion port 22 is close to the edge of the horizontal surface 2a ′ of the conveyor belt 2, it is possible to immediately shift to the insertion port 22 at a short distance from the conveyor belt 2, and only a lightweight object is efficiently used. Can be separated. Further, the guide plate 51 smoothly guides the chute 23.

  The conveyor belt 2 in the air injection direction does not have a vertical surface, has a horizontal surface 2a ′, and the charging port 22 of the chute 23 is located in the area of the horizontal surface 2a ′. An object can be smoothly introduced into the inlet 22 of the chute 23.

  Further, the conveyor belt 2 in the blowing area T can be vibrated up and down by the rotating single vibration applying roller 18, and the air can be efficiently injected by jetting air along the axial direction of the vibration applying roller 18. Only the light weight can be separated from the mixed waste material.

  In addition, heavy concrete blocks, crushed stones, and the like that pass through the wind power sorter 6 are not blown away by the air flow, and are therefore conveyed downstream by the conveyor belt 2. Therefore, since the light weight in the mixed waste material is removed by the wind sorting device 6, the material from which the light weight (light foreign matter) has been removed, that is, the concrete as a product, is discharged from the outlet portion 37 of the shielding box 33. Only crushed materials, crushed stones, etc. go out, and the carrier rollers 4-5 and thereafter are conveyed upstream by the conveyor belt 2 which has become trough again.

  Since the upper surface of the conveyor belt 2 on which the wind sorting is performed is covered by the shielding box 33, and the inlet portion 36 and the outlet portion 37 are shielded by the scattering prevention plates 35 and 38, the wind separation. It is possible to effectively prevent the dust generated by the operation from flowing out of the shielding box 33.

  Since the lightweight object thrown into the chute 23 falls on the upper chute part 24 and a relatively large lightweight object (light foreign matter) such as plastic and wood pieces cannot pass through the lattice 41a of the partition net 41, the first The first chute part 26 is dropped downward through the space S without falling on the two chute parts 27, and is dropped and accumulated in the first lightweight collection box 28.

  Granules such as concrete powder (for example, concrete powder having a diameter of about 5 mm or less) contained in the lightweight material pass through the lattice 41a of the partition net 41 and fall on the second chute portion 27, and the second lightweight material. Drops are accumulated in the collection box 29.

  Further, among the granular materials such as the concrete grains, those falling in the direction of the first chute portion 26 abut against the surface of the guide plate 42 and reflect in the direction of the partition net 41 in the direction of arrow I. Particulate matter such as concrete grains can also pass through the grid of the partition net 41 and be guided in the direction to the second chute portion 27 to be dropped into the second lightweight collection box 29.

  Further, for particulate matter such as concrete particles that have fallen to the first chute portion 26 and have passed through the space S, the path is driven by the air blown from the blow nozzle 43 in the direction of arrow K (direction of the partition net 41). Can be changed to the direction of the partition net 41, so that these granular materials such as concrete grains also pass through the lattice 41a of the partition net 41 and are guided in the direction of the second chute portion 27, and the second lightweight object collection box. 29 can be dropped.

  Accordingly, the lightweight material put into the chute 23 is accurately and efficiently used for light-weight foreign matters such as plastic and wood pieces as foreign matters, and granular matters such as concrete grains as products (for example, concrete powder having a diameter of about 5 mm or less). Can be separated.

  A concrete block (diameter of 40 mm or less) as a product that has passed through the wind sorting apparatus 6 falls from the end of the conveyor belt 2 as described above and is collected as a product at a collection location (not shown) as a product. Is done. Since the granular material such as concrete grains of about 5 mm or less collected in the second lightweight collection box 29 becomes a product having a diameter of 40 mm or less, it is finally returned to the collection place as a product. .

  In the present invention, as described above, in the state in which debris, crushed stone, etc. (mixed waste material) are transported and separated in a predetermined area by floating heavy and light objects on the conveyor belt 2 in the traveling direction of the conveyor belt 2. By blowing in the orthogonal direction, only a lightweight object can be efficiently blown toward the inlet 22. In addition, the lightweight material introduced into the insertion port 22 is further divided into relatively large lightweight materials (light foreign matter) such as plastics and wood pieces as foreign matters and granular lightweight items such as concrete powder that can be used as products in the branching portion 25. Can be separated and collected efficiently.

  Therefore, among the light-weight items selected by wind power, it is possible to further separate and collect fine granular materials (product fine portions, second light-weight items) such as concrete powder having a diameter of about 5 mm or less, which can become products, A highly recyclable wind power sorting device can be realized.

  Moreover, since the conveyor belt 2 of the ventilation area T can be vibrated up and down by the single vibration imparting roller 18, an effective wind power sorter can be realized with a simple configuration.

  Further, the second air blowing nozzle 43 is provided in the chute 23, and a light object is blown off in the direction of the partition net 41 by the air blowing from the nozzle 43, so that a relatively large light material (light foreign material) as a foreign material is produced. It is possible to more accurately perform separation from a granular lightweight material such as concrete powder to be obtained.

  Moreover, since the granular material which should originally transfer to the 2nd chute part 27 can be made to contact | abut to the guide plate 42, and can be reflected in the direction of the partition net | network 41, a more accurate classification of a lightweight thing can be performed.

  Also, a blower 15 for blowing air to the blower nozzle 8, the blower nozzle 8, the vibration applying roller 18, the shielding box 33, the inlet 22, the chute 23 having the first and second chute parts 26, 27, etc. Is configured so that it can be fixed to the existing machine frame 3 that supports the conveyor belt 2, for example, an existing conveyor device that transports debris, crushed stone, etc. (mixed waste) in a rear cycle factory such as building waste In addition, the wind sorting apparatus according to the present invention can be attached without significant modification, and an extremely versatile wind sorting apparatus can be provided.

  Moreover, it is possible to effectively prevent dust and the like accompanying the blowing of the lightweight object from being scattered outside the shielding box 33.

  Further, as in the present embodiment (see FIG. 1), the air outlet 8b ′ of the blower nozzle 8 is inclined upward along the upward inclination of the conveyor belt 2 even when the belt conveyor 2 has an upward inclination. By installing in a state, the wind power sorter according to the present invention can be installed without any trouble. Of course, it can also be installed in a horizontal state or a downwardly inclined conveyor device.

Moreover, although the conveyor apparatus 1 showed the trough type conveyor belt 2 in the said embodiment, even if it is not only a trough type but a flat conveyor belt, it is applicable.
Also, above

  The wind power sorting apparatus according to the present invention can be widely used as an apparatus for separating lightweight materials from heavy crushed materials in, for example, a recycling factory for recycling building waste materials.
