Description

  The present invention relates to a suction wind type sorting apparatus for sorting raw materials such as building waste and mixed industrial waste into materials that can be easily recycled. More specifically, the present invention relates to a suction wind type sorting device that can easily sort into materials according to size and weight with a small and simple configuration.

  Construction waste such as concrete waste and asphalt waste is discharged as construction by-products (construction waste) in construction work, dismantling work, civil engineering work, etc. This construction by-product is required to be effectively used rather than discarded as industrial waste. That is, the building waste material may be reused as a recycled roadbed material or the like by performing coarse sieving by dividing it into an object having a predetermined size (for example, 40 mm) or more and an object having a predetermined size or less by a sieve device. However, building waste materials contain various materials such as wood chips, paper, and plastic, and cannot be reused as they are.

In other words, what is separated below a predetermined size can be used as recycled roadbed materials, for example, but if there are many impurities (trash) such as wood chips, paper, plastic, etc. in the building waste, It cannot be reused for recycled roadbed materials. Therefore, it was necessary for the construction waste materials to be manually removed by the operator to sort and remove wood chips, paper, plastics, and the like.
However, the work of removing impurities from building waste and mixed industrial waste by hand sorting is a very difficult task. In addition, small mixed industrial waste (for example, 40 mm or less) is not easy to manually sort and is often landfilled. Therefore, various sorters, sort methods, and sort systems that can sort automatically have been proposed. Such a sorter will be further described with reference to patent literature as an example.

  As a conventional construction waste treatment system, a vibration sieving device having a screen and a vibration imparting mechanism, an impurity removing device having a suction nozzle, a cyclone and a fan device, and a first sending air from below to a slit network below the suction nozzle What is equipped with the ventilation mechanism is known (for example, refer patent document 1). In the construction waste processing system disclosed in Patent Document 1, construction waste is screened on a screen of a vibration sieving device, and the over material over the screen is sent to the slit mesh side, and relatively lightweight impurities are removed by suction using a suction nozzle. Has been.

In addition, as a method for recovering recycled roadbed materials using wind sorting, concrete waste, asphalt waste, etc. are supplied to a crushing device and crushed to a predetermined size, and the crushed waste is supplied to a sieving device to obtain a predetermined particle size. There is known a method of collecting the recycled aggregate and the recycled roadbed material by sieving every time (see, for example, Patent Document 2). In the recovery method of Patent Document 2, among the components falling from the lower end of the tilt without being able to pass through the lower screen of the vibrating tilt screen by the blower, the light weight component is blown off and can be recovered separately from the weight component dropped without being blown off. .

The elastic support may be another elastically supportable member such as rubber. The sieve frame 11 is provided with a vibration device 13. When the vibration motor 14 rotates, the vibration device 13 rotates through a belt and causes the sieve frame 11 to vibrate. That is, the vibration device 13 has a rotating body provided with an eccentric weight, and vibration is generated by rotating this rotating body, so that a vibrating operation is performed. Needless to say, the vibration device may be another type of vibration device as long as it can vibrate the inclined screen.

  An inclined screen 12 having a mesh (sieving mesh) of a predetermined size (for example, 40 mm) is provided inside the sieve frame 11. The inclined screen 12 is inclined at a predetermined angle such that the rear side (hopper 54 side) is high and the front side is low. The raw material G supplied to the inclined screen 12 moves in the direction of the arrow Q from the hopper 54 side to the front side by this inclination and the vibration applied to the inclined screen 12. A wall surface on the front side of the sieve frame 11 forms a reflecting plate 11a, and a space portion 11b having a predetermined interval is formed between the reflecting plate 11a and the inclined screen 12.

  The raw material G introduced from the hopper 54 is sieved by the vibration sieve sorting means 10, and the raw material having a predetermined size or less falls through the mesh of the inclined screen 12 and is sorted. The dropped raw material falls on the belt 62 of the belt conveyor 60 through the hopper 65. The raw material on the belt 62 is collected at the sorting and collecting position on the rear side of the suction wind type sorting apparatus 1 as the material MA having a predetermined size or less by the movement of the belt 62.

  A lower side 51 d of the U-shaped suction support part 51 in a front view is fixed to the main body 50. A suction sorting means 20 is suspended from the upper side 51 a of the suction support portion 51. That is, the suction frame body 21 of the suction sorting means 20 is suspended by the suspension bolt 51b and fixed to the upper side 51a of the suction support portion 51 by a nut 51c or the like. A mesh conveyor 22 is supported on the suction frame body 21.

  The mesh conveyor 22 includes one sprocket 23a, the other sprocket 23b, a mesh winding belt 24 wound between both sprockets, a mesh conveyor drive motor 25, and the like. The mesh winding belt 24 has sprocket engagement holes formed at both ends, and the sprocket engagement holes are rotatably supported by both sprockets 23a and 23b. One sprocket 23a and the other sprocket 23b are rotatably supported by the suction frame body 21 via a shaft body. The mesh winding belt 24 is an endless belt having a predetermined width and length.

  The suction frame body 21 is provided with a mesh conveyor drive motor 25. A belt 28 is wound between a pulley 26 provided on the output shaft 25a of the mesh conveyor drive motor 25 and a pulley 27 provided on a shaft body 23c supporting one sprocket 23a. That is, when the mesh conveyor drive motor 25 rotates, one sprocket 23a rotates via the pulley 26, the belt 28, the pulley 27, and the shaft body 23c. When one sprocket 23a rotates, the mesh winding belt 24 and the other sprocket 23b rotate accordingly.

  The mesh winding belt 24 is a mesh belt having a mesh of a predetermined size, and allows air to flow through the mesh. Note that the mesh winding belt is a thin plate belt having a plurality of holes of a predetermined size (for example, round holes, square holes, long holes, turtle shell holes), a long mesh belt, or the like. In short, what is necessary is that the belt can be wound between the sprockets and the belt surface can flow air. The mesh winding belt is preferably made of a thin metal plate, a synthetic resin, or the like.

  The mesh-shaped winding belt 24 is supported by the one sprocket 23a and the other sprocket 23b on the winding movement trajectory extending in a direction crossing the direction in which the raw material G moves on the inclined screen 12, and the winding movement is performed. To do. Further, the mesh winding belt 24 is provided such that at least a belt surface moving on the inclined screen 12 side has a predetermined interval with respect to the screen surface of the inclined screen 12 and moves in parallel or substantially in parallel. Wrap it.

As shown in FIG. 4, a suction nozzle 32 provided on one side of the first duct 31 has a suction port substantially downward (inclined screen 12 side) between mesh winding belts 24 to be wound. It is arranged toward. A blower 33 is connected to the other side of the first duct 31. The inside of the first duct 31 forms a first air circuit 31a, and the air is blown in the direction of the arrow U5. As the blower 33, a blower blower, a blower fan, or the like is suitable.
In other words, since the suction port of the suction nozzle 32 is located in the vicinity of the inclined screen 12, the raw material G on the inclined screen 12 is reliably sucked onto the surface of the mesh-shaped winding belt 24 to be wound. Can do. The blower 33 can also be sucked without using a large fan.

  A second duct (not shown) is provided between the blower 33 and the blowout pipe 41. The second duct forms a second air circuit 36 and third air circuits 36a and 36b. The wind generated by the blower 33 is blown in the directions of arrows U, U1, U2 through the second air circuit 36 and the third air circuits 36a, 36b. Stop valves 37a and 37b are provided between the second air circuit 36 and the third air circuits 36a and 36b. A cleaner 35 is connected to the blower 33 through a fourth air circuit. The cleaner 35 purifies a part of the circulating air, and then discharges it to the outside of the suction wind power sorter 1. Thus, it is possible to prevent the circulating air from becoming dirty air for a predetermined amount or more.

  The air blowing means 40 includes a blowing pipe 41, a nozzle 42, and the like. A plurality of nozzles 42 are formed in the blowing pipe 41 in the axial direction. The nozzle 42 may have a blowout port formed in a circular hole, an elliptical hole, a square hole, or the like. The air blown out from the nozzle 42 of the blowing pipe 41 flows in a direction in which the material is levitated (in the direction of arrow U3) and in a direction in which air is blown out toward the material that has dropped from the guide portion 12a (in the direction of arrow U4). . That is, the air blown out from the blowing pipe 41 of the air blowing means 40 has a function of assisting suction of a light material that is not less than a predetermined size by being levitated, and a material blown off by the wind force of the blown air It has a function of wind power sorting means for sorting materials that are not blown away.

  In the vicinity of the blowing pipe 41, an adjustment damper (flow adjustment plate) 48 for adjusting the air flow direction is rotatably provided. The adjustment damper 48 can be rotated by operating the handle 47, and can be rotated from the outside of the suction wind type sorting apparatus 1. By this turning operation, it is possible to adjust the amount of air flowing in the direction in which the material is floated (direction of arrow U3) and the amount of air flowing in the direction of blowing air toward the material (direction of arrow U4).

  A guide portion 12 a is formed on the front side of the inclined screen 12. The guide part 12a allows the air blown from the nozzle 42 of the blowout pipe 41 to flow, and moves the raw material G having a predetermined size or more that has passed through the space part 11b along the inclination. The guide portion 12a is preferably formed of a metal member having a predetermined interval and extending in a direction parallel to the moving direction of the raw material G, and air can flow from the gap between the members.

The operation of the suction wind power sorter 1 according to Embodiment 1 will be described.
Raw materials G such as building waste materials crushed by a crusher or the like are fed from a hopper 54. The charged raw material G falls on the inclined screen 12 of the vibration sieve selecting means 10. The raw material G is sorted by the vibration sieving operation in the inclined screen 12, and the raw material having a predetermined size or less passes through the mesh (sieving mesh) of the inclined screen 12. The passed raw material having a predetermined size or less falls on the belt 62 of the belt conveyor 60 through the hopper 65. The raw material dropped on the belt 62 is sorted and collected as a material MA having a predetermined size or less at a position on the rear side of the suction wind type sorting device 1.

  The raw material that has not fallen from the inclined screen 12 moves forward by the inclination of the inclined screen 12 and the vibration sieving operation of the inclined screen 12. At this time, the raw material G that has jumped on the inclined screen 12 collides with the reflecting plate 11a and does not fall as it is. The raw material which collided with the reflecting plate 11a is returned to the rear side, and the momentum is removed. The raw material G that is on the inclined screen 12 and that has passed through the space 11b below the reflector 11a and has a predetermined size moves to the guide 12a.

  Among the raw materials G larger than the predetermined size moved to the guide portion 12a, the lighter ones have a weight that is lifted by the air blown from the nozzle 42 of the lower blowing pipe 41 and a suction force sucked by the upper suction nozzle 32. Due to the synergistic effect, suction is applied to the surface of the mesh-shaped winding belt 24. The mesh winding belt 24 rotates in the D direction (the clockwise direction in FIG. 2). The light raw material sucked on the surface of the mesh winding belt 24 moves together with the mesh winding belt 24. When the sucked light raw material loses the suction force of the suction nozzle 32 and the levitation force from the nozzle 42 of the blowing pipe 41, it falls from the surface of the mesh-shaped winding belt 24 by its own weight in the direction of arrow R, and the suction wind type On the side of the sorting apparatus 1, the material MB is sorted and collected as a material MB having a predetermined size or more and a light weight.

  Among raw materials larger than a predetermined size moved to the guide part 12a, those not sucked by the mesh winding belt 24 fall from the front side of the guide part 12a. When a raw material larger than a predetermined size is about to fall, air is blown out from the nozzle 42 of the blowing pipe 41 toward the raw material. Therefore, the raw material blown off by the wind force of the blown air and the blowing air Can be sorted into raw materials that are not blown by wind power. The raw material that is not blown away by the wind force of the air blown from the nozzle 42 of the blowout pipe 41 falls as it is. That is, the material MD is sorted and collected in the direction of the arrow S in the direction of arrow S.

  Among the raw materials larger than the predetermined size moved to the guide part 12a, the raw material blown off by the wind force of the blown air is selected as the material MC having the predetermined size or more and the medium weight, and the arrow T Recovered in the direction. The material MC having a medium size and a weight that is not less than the predetermined size in the first embodiment is the material MB that is not less than the predetermined size and light in weight, and is not less than a predetermined size. It is intermediate between heavy materials MD.

  The adjustment damper 48 adjusts the flow of air blown from the nozzle 42 of the blowout pipe 41. That is, as shown in FIG. 5A, by adjusting the counterclockwise rotation position, the amount of air flowing on the direction side (in the direction of the arrow U3) to be levitated by the wind force of the blown air can be increased. . When the adjustment damper 48 is in this adjustment position, the amount of air flowing in the direction of blowing air toward the material (the direction of the arrow U4) decreases. For example, when the emphasis is placed on the function of assisting (lifting) the suction and sorting of the material having a weight larger than a predetermined size by the suction and sorting means 20, the rotation position may be adjusted to the counterclockwise rotation position from the intermediate position. .

  As shown in FIG. 5B, the amount of air flowing toward the direction of levitation by the wind force of the blown air (in the direction of the arrow U3) can be reduced by adjusting the rotation position in the clockwise direction. When the adjustment damper 48 is in this adjustment position, the amount of air flowing in the direction of blowing air toward the material (the direction of the arrow U4) increases. For example, when emphasis is placed on the function of sorting by the wind power sorting means, it may be adjusted to the rotational position on the clockwise direction side from the intermediate position.

Further, when both the function of assisting the suction sorting by the suction sorting means and the function of the sorting function by the wind power sorting means are performed equally, it may be adjusted to the rotation position near the intermediate position.
As described above, it is preferable to adjust the position of the adjustment damper 48 according to the type, size, weight, material use, and the like of the material to be selected.

  More specifically, the raw materials will be explained as building waste such as concrete waste and asphalt waste. The building waste material thrown in from the hopper 54 falls on the inclined screen 12 of the vibrating screen sorting means 10, is sorted by the vibrating screen operation on the tilted screen 12, and falls on the belt conveyor 60. The material of a predetermined size or less dropped on the belt conveyor 60 is sorted and collected on the rear side of the suction wind power sorter 1 as a recycled material that can be recycled (reused) into recycled roadbed material, recycled aggregate, and the like. .

  The building waste material that has not fallen from the inclined screen 12 has a force that causes paper, plastic, wood chips, wood fragments, etc. to float by the air blown from the nozzle 42 of the lower blowing pipe 41 in the guide portion 12a of the inclined screen 12 Due to the synergistic effect of the suction force sucked by the suction nozzle 32, the suction is performed on the surface of the mesh winding belt 24. The sucked paper, plastic, wood pieces, etc. are moved with the winding motion of the mesh winding belt 24 in a state of being sucked by the mesh winding belt 24, and at the position where the levitation force and suction force are reduced. As unnecessary material (or dust), it is sorted and discharged to the side of the suction wind type sorting device 1.

  The building waste remaining without being sucked by the mesh winding belt 24 falls from the front side of the guide portion 12a. When building waste material that has not been sucked is falling, the wind force of the air blown from the nozzle 42 of the blowing pipe 41 is not less than a predetermined size and a material that is heavier than a predetermined size and heavy. Thus, the material is sorted into medium materials, and each is collected (or discharged) at a predetermined position. Since this material does not include unnecessary materials such as dust, it can be recycled to recycled roadbed material by performing crushing treatment again.

FIG. 6 is a diagram illustrating a modified example of the adjustment damper of the suction wind type sorting apparatus 1 according to the first embodiment.
In the modification of the first embodiment, a slidable slide damper 81 is provided in a slide groove formed in the adjustment damper 80. In the configuration in which the slide damper 81 is provided, the air flow amount can be adjusted by adjusting the slide position of the slide damper 81 as shown in FIG. In other words, the adjustment damper 80 provided with the slide damper 81 can adjust the air flow rate more easily than the adjustment damper described above.

The raw material G supplied to the inclined screen 112 moves forward in the direction of the arrow Q by the inclination and the vibration applied to the inclined screen 112.

  The charged raw material is sieved by the vibrating screen sorting means 110, and the raw material having a predetermined size or less falls through the mesh of the inclined screen 112 and is sorted. The fallen material is collected at a sorting and collecting position on the rear side of the suction wind type sorting apparatus 101 as a material MA having a predetermined size or less by moving the belt of the belt conveyor 60 in the arrow P direction.

  On the front end side of the inclined screen 112, there is provided a chute member 170 through which the raw material which has been sieved by the vibration sieve selecting means 110 and has not dropped, in other words, a raw material having a predetermined size or more moves. The chute member 170 is fixed to the front end portion of the sieve frame 111 and is formed of a bottom surface portion 170a and a side surface portion 170b. The bottom surface portion 170a is a member having a mesh shape, a long mesh shape, a lattice shape, a comb shape, or the like in which holes, grooves, and the like are formed, and air flow is very good. The chute member 170 is inclined at a second angle smaller than the first angle at which the inclined screen 112 is inclined. That is, the chute member 170 is substantially horizontal or loosely inclined with respect to the horizontal plane. The second angle at which the chute member 170 is inclined may be, for example, an inclination of 0 to 5 degrees. In other words, the second angle at which the chute member 170 is inclined is significantly smaller than the first angle at which the inclined screen 112 is inclined.

That is, the charged and sieved raw material moves temporarily on the bottom surface portion 170a, which is a gentle inclined surface, or moves at a significantly slow speed. In other words, it moves so as to be pushed to the front side of the chute member 170 by the force pushed by the raw material that moves later and the applied vibration.
In addition, the chute member 170 is good to be able to adjust an attachment angle with respect to the sieve frame 111. FIG. For example, it is preferable that the attachment angle can be adjusted between the chute member shown by the solid line in FIG. 10 and the chute member shown by the two-dot chain line.

A raw material of a predetermined size or larger on the chute member 170 is sucked and moved by a suction sorting means (second sorting means) 120 and a light raw material of a predetermined size or larger, and a predetermined size not sucked or larger. The material is sucked and sorted into heavy materials. The raw material that is not sucked and is heavier than a predetermined size moves so as to be pushed out on the chute member 170, is discharged from the front end side, and falls onto the second belt conveyor 195. The fallen raw material that is larger than the predetermined size is transported in the direction of arrow R by the belt of the second belt conveyor 195, and has a predetermined size on one side (the right side in FIG. 8) of the suction wind power sorter. It is sorted and collected as material MD which is more than that and heavy.
The raw material having a lighter weight than the predetermined size is passed through the suction sorting means 120 and the carry-out chute 175 to the other side (left side in FIG. 8) of the suction wind type sorting device. Thus, the material MB is sorted and collected as a light material MB. The suction selection means 120 will be further described with reference to FIGS.

  As shown in FIGS. 7 to 9, the support base 181 is provided with a column 182 and a cantilever member 182 a. A suction frame 121 of the suction sorting means 120 is suspended from the cantilever member 182a. That is, the attached portion 121c of the suction frame 121 is suspended by the suspension bolt 151b, and is fixed to the cantilever member 182a by the nut 151c or the like. A mesh conveyor 122 is supported on the suction frame body 121.

  Above the chute member 170, a suction frame 121 of the suction sorting means 120 is provided. The suction frame 121 has a substantially rectangular parallelepiped shape, and the lower side is open to form a suction port 121a. A triangular suction port 121d in a side view is formed on the side of the carry-out chute 175 of the suction port 121a. The triangular suction port 121d is for gradually reducing the sucked wind force from the suction port 121a side, and assists the sucked light raw material to fall by its own weight. A suction duct connection port 121b to which the suction duct 183 is connected is formed on one side surface of the suction frame body 120.

A pair of attachment members 165a and 165b are fixed to both side surfaces of the suction frame 120 by fastening means such as bolts in a side view. The attachment member 165a and the attachment member 165b are preferably made of groove steel or the like.
Bearing units 160a and 160d are attached to the pair of attachment members 165a and 165a. Bearing units 160b and 160c are attached to the pair of attachment members 165b and 165b. As shown in FIG. 10, the bearing units 160c and 160c rotatably support both ends of a shaft body 162c provided with a support roller 123c. The bearing units 160d and 160d rotatably support both ends of a shaft body 162d provided with a support roller 123d. Similarly, the bearing units 160a and 160a rotatably support both ends of the shaft body 162a on which the support roller 123a is provided, and the bearing units 160b and 160b rotatably support both ends of the shaft body 162b on which the support roller 123b is provided. is doing.

  A mesh-like winding belt 124 is wound around the support rollers 123a, 123b, 123c, and 123d so as to be rotatable on a substantially trapezoidal movement locus as shown in FIGS. As shown in FIG. 10, a mesh conveyor drive motor 125 is provided on one side of the shaft body 162c to drive the shaft body 162c to rotate. That is, when the winding belt drive motor 125 rotationally drives the shaft body 162c, the mesh-shaped winding belt 124 rotates while being supported by the support rollers 123a, 123b, 123c, and 123d.

The mesh conveyor 122 includes support rollers 123a to 123d, a mesh winding belt 124 wound between the support rollers 123a to 123d, a mesh conveyor drive motor 125, and the like.
A guide portion 124a is formed on the mesh winding belt 124, and is engaged with guide groove portions formed on the support rollers 123a, 123b, 123c, and 123d. The mesh winding belt 124 is prevented from meandering by rotating with the guide portion 124 a engaging with the guide groove portion of the support roller. The mesh winding belt 124 is an endless belt having a predetermined width and length.

  The mesh-shaped winding belt 124 may be a thin belt, a long mesh belt or the like in which a plurality of holes of a predetermined size (for example, round holes, square holes, long holes, turtle shell holes) are formed. In short, it is only necessary that the support roller can be wound and the air flow is very good through the hole in the belt surface. The mesh winding belt is preferably made of a thin metal plate, a synthetic resin, or the like.

  The mesh-shaped winding belt 124 is supported by the support rollers 123a, 123b, 123c, and 123d on the winding motion trajectory extending in the direction crossing the direction in which the raw material moves on the inclined screen 112, and performs the winding motion. . Further, the mesh winding belt 124 is provided such that at least a belt surface that moves above the chute member 170 has a predetermined interval with respect to the surface of the chute member 170 and moves in parallel or substantially in parallel. Wrap it.

  A plurality of (in this embodiment 2, both sides of the suction frame 121 and the both sides of the suction frame 121 are arranged on the suction port 121a side of the suction frame 121 so that the wind is sucked by the mesh winding belt 124 so as not to be deformed (not drawn in) Five guide rollers 164, 164,... Are provided at the center. As this guide roller 164, what is called a cam follower (roller follower) can be used. The guide roller 164 has a shaft portion inserted through a hole formed in the suction frame body 121, and is fixed to the suction frame body 121 with a nut 164a. The suction frame 121 is provided with a roll brush-like light material separating member 163. That is, the tip of the brush of the light material separating member 163 enters the mesh of the mesh-shaped winding belt 124, and the mesh-shaped winding belt 124 and the sucked light raw material can be separated.

  Further, the mesh winding belt 124 is provided with a horizontal crosspiece 124b at every predetermined interval in the longitudinal direction. This horizontal crosspiece 124b prevents the long and thin raw material from being adsorbed by the mesh-like winding belt 124, and prevents the sucked light raw material from dropping by its own weight at a position where the suction force is reduced or eliminated. It is for ease. Note that the mesh-shaped winding belt may not be provided with a horizontal crosspiece.

  One of the suction ducts 183 is connected to the suction duct connection port 121b of the suction body 121. The other side of the suction duct 183 is connected to the suction port of the blower 184. An exhaust duct 186 in which an exhaust port 187 is formed is connected to the discharge port of the blower 184. The blower 184 performs a blowing operation with a fan or the like driven by the blower drive motor 185. The blower 184 is controlled by a blower control panel 188 having an operation panel provided on the front surface. The operator can adjust the output of the blower drive motor 185 and adjust the wind force generated by the blower 184 using the blower control panel 188. For example, the wind force adjustment of the blower 184 corresponding to the suction force sucked through the belt surface of the mesh winding belt 124 can be performed according to the type of raw material to be selected, the type of material sucked as a light material, and the like. . A blower 180 is constituted by the blower 184, the suction duct 183, the exhaust duct 186, the blower drive motor 185, and the like.

Next, the operation of the suction wind type sorting apparatus 101 will be described.
The raw material G is thrown into the sieve frame 111 from the upper rear side of the sieve frame 111 as shown by the arrow shown in FIG. The charged raw material G is sieved in the sieve frame 111, and a raw material smaller than the mesh of the inclined screen 112 falls on the belt conveyor 60. The dropped raw material is conveyed to the rear of the suction wind type sorting device by the belt conveyor 60. The conveyed raw material is sorted and collected behind the suction wind type sorting device as a material MA having a predetermined size or less.

  The raw material that is sieved in the sieve frame 111 and does not fall from the inclined screen 112 is a raw material having a predetermined size or more, and moves on the chute member 170 along the vibration and inclination of the inclined screen 112. Since the chute member 170 is inclined more gently than the inclined screen 112, a raw material having a predetermined size or more is in a staying state or a state close to staying for a while. That is, it moves little by little so that it is pushed by the raw material which moves on the chute member 170 later.

  Above the chute member 170, suction sorting means 120 is provided. The suction sorting means 120 is operated by the blower 184 so that the air below the chute member 170 and in the vicinity of the chute member 170 is sucked from the suction port 121a of the suction frame body 121 through the suction duct 183 and the like. The air is exhausted from the exhaust port 187. That is, the air below or in the vicinity of the chute member 170 is sucked from the suction port 121a through the chute member 170 and the mesh-shaped winding belt 124 that are formed in a shape in which air circulation is very good. Therefore, the light raw material on the chute member 170 is sucked by the mesh winding belt 124 by this suction force, and moves in the D1 direction by the winding motion of the mesh winding belt 124.

  At this time, since the raw material on the chute member 170 is moving little by little at a slow speed, the air below or near the chute member 170 is placed in a state where the air is sucked from the suction port 121a for a long time. It will be. Further, since the chute member 170 vibrates integrally with the sieve frame 111, the raw material on the chute member 170 also vibrates. That is, the mesh winding belt 124 can reliably suck and wind a light raw material.

  Since the mesh-like winding belt 124 loses the suction force when it deviates from the position facing the suction port 121a, the light raw material falls off the mesh-like winding belt 124 due to its own weight. The fallen light raw material is sorted and collected as a light raw material MB having a predetermined size or more in a collection box 176 provided on the other side (the left side in FIG. 8) via the carry-out chute 175. The At this time, a triangular suction port 121d is formed in the suction port 121a, and the suction force gradually decreases, so that the mesh winding belt 124 and the light raw material can be easily separated. Further, the horizontal crosspiece 124b formed on the mesh winding belt 124 and the light material separating member 163 provided on the suction frame 121 also assist the separation between the mesh winding belt 124 and the light raw material, and the separation. It works to make it even easier.

  The material that is on the chute member 170 and is not sucked by the suction sorting means 120 moves on the chute member 170 so as to be pushed out by the weight of the raw material that comes later, the applied vibration, etc., and the front end of the chute member 170 It is discharged from the side and falls. The dropped raw material is sorted and collected by the second belt conveyor 195 on one side (the right side in FIG. 8) as a heavy material MD having a predetermined size or more.

More specifically, the raw materials will be explained as building waste such as concrete waste and asphalt waste. The input construction waste material is sorted by the vibration sieve operation in the vibration sieve sorting means 110 and falls onto the belt conveyor 60. The material having a predetermined size or less dropped on the belt conveyor 60 is sorted and collected on the rear side of the suction wind type sorting device 101 as a recycled material that can be recycled (reused) as recycled roadbed material, recycled aggregate, or the like. .
When the raw material is a mixed industrial waste, the suction wind type sorting device 101 sorts and collects the remaining sand as a material having a predetermined size or less. That is, the remaining sand is selected and collected as a recyclable recycled material.

  Of the construction waste and the mixed industrial waste that have not fallen from the inclined screen 112, the lighter one is sucked from the chute member 170 to the mesh winding belt 124. The sucked paper, plastic, wood piece and the like move together with the winding motion of the mesh winding belt 124 while being sucked by the mesh winding belt 124, and at the position where the suction force is reduced, unnecessary materials ( Or, the waste is sorted and discharged to the other side of the suction wind power sorter 101 as waste.

The construction waste material that remains without being sucked by the mesh winding belt 124 is made of a material having a weight larger than a predetermined size and a heavy weight via the second belt conveyor 195. Sorted and collected on the side. Since this material does not include unnecessary materials such as dust, it can be recycled to recycled roadbed material by performing crushing treatment again. Therefore, it may be conveyed to the crusher by a belt conveyor or the like.
The mixed industrial waste that remains without being sucked by the mesh winding belt 124 is sucked by the wind-powered sorter as “debris” that is a material having a weight larger than a predetermined size and heavy through the second belt conveyor 195. Sorted and collected on one side of the device 101.
