Description

  The present invention relates to a suction wind type sorting device for sorting 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 apparatus capable of sucking and sorting materials with a stable and constant suction force.

  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 not discarded as industrial waste, but is required to be used effectively. 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. As such a sorting device, the present applicant has developed the suction wind type sorting device of Patent Document 1.

  The suction wind type sorting device of Patent Document 1 applies vibration to an inclined screen having a sieve having a predetermined size, while the raw material supplied from one side is moving from one side to the other side. In addition, there is provided sorting means for dropping a material having a predetermined size or less to the lower side of the inclined screen through the sieve screen. Further, an upper end on the other side of the inclined screen is provided so as to cross the moving direction of the raw material, is an endless belt capable of air circulation and having a predetermined width, and extends in the crossing direction. A winding belt that can move on the winding movement trajectory is provided. In addition, the winding belt is provided in the middle of the winding belt so that the suction port faces the inclined screen side, and suction air is generated so that the raw material which is not less than the predetermined size and is light in weight is the winding belt. A suction frame for sucking the surface is provided.

  In the suction wind type sorting apparatus of Patent Document 1, the suction port of the suction frame body opens over a large area over the entire surface. Therefore, the flow velocity of the suction air changes due to the frictional resistance between the inner surface of the suction frame and the suction air, and the suction force varies depending on the location of the suction port. Further, since the suction air becomes a turbulent flow, the suction force becomes unstable, and a predetermined suction force may not be obtained.

  An inclined screen 112 having a mesh (sieving mesh) of a predetermined size (for example, 40 mm) is provided inside the sieve frame 111. The inclined screen 112 is inclined at a predetermined angle (first angle) so that the rear side (one side) is high and the front side (chute member 170) side (the other side) is low. 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.

It is sorted and collected as material MB which is more than that and light in weight. The suction sorting means 120 will be further described with reference to FIGS.

  As shown in FIGS. 1 to 3, the support 181 is provided with a column 182, a beam member 151 that connects the upper ends of the columns 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 cylindrical suction duct connection port 121 b to which the suction duct 183 is connected is formed on one side surface of the suction frame body 121. The suction duct may be another polygonal duct whose cross-sectional shape orthogonal to the longitudinal direction includes a square shape. In that case, the suction duct connection port is a quadrangular or polygonal connection port that matches the shape of the duct. Further, a plurality of suction ducts may be provided. That is, by making the cross-sectional area of the suction duct a predetermined size, it is possible to cope with an increase in the size of the suction wind type sorting device.

  A pair of attachment members 165a and 165b are fixed to both side surfaces of the suction frame body 121 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 FIGS. 3 and 4, 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 able to rotate on a substantially trapezoidal movement locus as shown in FIGS. As shown in FIG. 4, 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 mesh conveyor drive motor 125 rotates and drives the shaft body 162c, the mesh 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. As shown in FIG. 4, the mesh winding belt 124 is formed with a guide portion 124a and is engaged with guide groove portions formed in the support rollers 123a, 123b, 123c, and 123d. The mesh winding belt 124 is prevented from meandering when the guide portion 124a rotates by engaging with the guide groove portions of the support rollers 123a, 123b, 123c, and 123d. 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. Good. In short, the mesh winding belt 124 only needs to be able to wind between the support rollers 123a to 123d and to have a very good air flow through the hole in the belt surface. The mesh winding belt 124 is preferably made of a thin metal plate, 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. . The mesh winding belt 124 is provided such that at least a belt surface that moves above the chute member 170 moves in parallel or substantially in parallel with a predetermined distance from the surface of the chute member 170. It is wound.

  On the unloading chute 175 side of the suction frame body 121, a roll brush-like light material separation member 163 is provided. 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 cylindrical suction duct connection port 121b of the suction frame 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.

  The detailed structure of the suction frame body 121 will be further described with reference to FIG. The first plate member 20 that covers the entire surface of the suction port 121a is fixed to the suction port 121a of the suction frame 121. The first plate member 20 is disposed in parallel or substantially parallel to the chute member 170 at the lower end of the inclined screen 112. In the first plate member 20, a plurality of circular holes 21 having the same diameter are uniformly formed on the entire surface of the first plate member 20.

  Therefore, the air sucked from the suction port 121a passes through the plurality of holes 21 formed uniformly on the entire surface of the first plate member 20, so that the flow velocity is constant over the entire surface of the suction port 121a and the layer Become a flow. Therefore, the suction force is constant over the entire surface of the suction port 121a, and a stable suction force can be obtained. The first plate member 20 having the plurality of holes 21 constitutes a dividing unit that divides the suction port 121a into a plurality of regions.

  If the diameter (area) of the hole 21 is increased, the suction force is decreased. If the diameter (area) of the hole 21 is decreased, the suction force is increased. Therefore, the diameter (area) of the hole 21 is set to an appropriate size. By setting, a predetermined suction force can be obtained. The shape of the hole 21 is not limited to a circle, and can be formed in an arbitrary shape such as a quadrangle, a rectangle, or a triangle.

  The total area of the plurality of holes 21 is smaller than the total area of the suction port 121a. Accordingly, the suction force is increased as compared with the case where the entire surface of the suction port 121a is open. Therefore, even if the amount of air blown by the blower 184 is constant, the width W of the suction port 121a (the length in the direction parallel to the moving direction of the raw material) can be increased, so that the area of the suction port 121a can be increased. The light raw material on the chute member 170 can be sucked effectively.

  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 by a belt conveyor or the like (not shown) as shown by arrows 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 apparatus 101 by the belt conveyor 60. The conveyed raw material is sorted and collected behind the suction wind type sorting device 101 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, the 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. In the suction sorting means 120, the air below the chute member 170 and in the vicinity of the chute member 170 is sucked from the suction port 121 a of the suction frame body 121 through the suction duct 183, etc. The air is exhausted from the exhaust port 187.

  That is, air below and near 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. Since the sucked air passes through the plurality of holes 21 formed uniformly on the entire surface of the first plate member 20, the flow velocity is constant over the entire surface of the suction port 121a and the flow becomes a laminar flow. The suction force is constant over the entire surface of the mouth 121a, and the suction force is stable. 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 direction D1 of FIG. 2 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 and in the vicinity of the chute member 170 is placed in a state of being sucked from the suction port 121a for a long time. . 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. 2) via the carry-out chute 175. The The 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 of the mesh winding belt 124 and the light raw material, making the separation even easier. To act.

  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. 2) 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.

In the regions 33, 34, 35, and 36 where the suction force is large, relatively heavy material such as plastic and wood pieces is sucked from the chute member 170 to the mesh winding belt 124. Therefore, a wide range of weight materials can be sucked from a relatively light material to a relatively heavy material.

  Next, the suction frame body of the 3rd Embodiment of this invention is demonstrated. FIG. 7 is a component diagram showing a single suction frame body according to the third embodiment of the present invention. FIG. 7A is a sectional view of the suction frame body, and FIG. 7B is a bottom view of FIG. 7A viewed from the arrow T direction. FIG. 4C is a longitudinal sectional view taken along line U-U in FIG.

In the regions 33, 34, 35, and 36 where the suction force is large, relatively heavy material such as plastic and wood pieces is sucked from the chute member 170 to the mesh winding belt 124. Therefore, a wide range of weight materials can be sucked from a relatively light material to a relatively heavy material.

  The total area of the plurality of holes 21 is smaller than the total area of the suction port 121a. Accordingly, the suction force is increased as compared with the case where the entire surface of the suction port 121a is open. Therefore, even if the amount of air blown by the blower 184 is constant, the width W of the suction port 121a (the length in the direction parallel to the moving direction of the raw material) can be increased, so that the area of the suction port 121a can be increased.

As shown in FIG. 9, a mesh conveyor 122 having the same shape as that of the first embodiment is supported on the suction frame body 121. The mesh conveyor 122 sucks a raw material having a predetermined size or more on the chute member 170.

  One of the suction ducts 183 is connected to the cylindrical suction duct connection port 121b of the suction frame body 121. The other side of the suction duct 183 is connected to the suction 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. An exhaust duct 186 and an exhaust circulation duct 186a are connected to two discharge ports (not shown) formed in the blower 184, respectively.

  The exhaust duct 186 is connected to the suction port 71 of the cyclone dust collector 70. An exhaust amount adjustment plate (not shown) is slidably inserted into the discharge port of the blower 184. The amount of exhaust flowing into the exhaust duct 186 is adjusted by sliding and adjusting the exhaust amount adjusting plate to change the area of the opening of the discharge port. The exhaust circulation duct 186 a is connected to the suction port 81 of the exhaust circulation frame 80 provided below the chute member 170. The upper part of the exhaust circulation frame 80 is connected to the periphery of the side surface 170 b of the chute member 170 by a bellows 82.

  The cyclone dust collector 70 is a double-type cyclone dust collector composed of an outer cyclone that primarily purifies exhaust gas and an inner cyclone that secondarily purifies exhaust gas that has been primarily purified. That is, the cyclone dust collector 70 includes an outer cylindrical portion 72, an inner cylindrical portion 73, a conical portion 74, an inner cylinder 75, an exhaust duct 76, a dust discharge box 77, a communication port 78, and the like.

  An inner cylindrical portion 73 having a short axial length is formed on the inner side of the outer cylindrical portion 72 erected vertically, near the upper end of the outer cylindrical portion 72 and concentrically with the outer cylindrical portion 72. A conical portion 74 having a smaller diameter toward the lower side is integrally formed at the lower end of the portion 73. An inner cylinder 75 is formed concentrically with the inner cylindrical portion 73 inside the inner cylindrical portion 73, and an exhaust duct 76 is connected to the inner cylinder 75. The exhaust duct 76 extends vertically upward, is bent in an inverted U shape and extends vertically downward, extends to the vicinity of the chute member 170 along the support base 181, and then the suction port of the exhaust circulation frame 80 described above. 81. A dust discharge box 77 is detachably attached to the lower end of the outer cylindrical portion 72.

  The space surrounded by the inner side of the outer cylindrical part 72 and the outer side of the inner cylindrical part 73, and the space surrounded by the inner side of the outer cylindrical part 72 and the outer side of the conical part 74 constitute an outer cyclone that primarily purifies the exhaust gas. ing. Further, the space inside the inner cylindrical portion 73 and the conical portion 74 constitutes an inner cyclone for secondary purification. Exhaust gas containing dust is supplied from the exhaust duct 186 through the suction port 71 to the outer cylindrical portion 72 in the tangential direction.

  As shown in FIG. 10A, the exhaust gas supplied to the outer cylindrical portion 72 is a space surrounded by the inner side of the outer cylindrical portion 72 and the outer side of the inner cylindrical portion 73, and the inner side of the outer cylindrical portion 72 and the cone. In the space surrounded by the outside of the part 74, the swirl flow rises. The coarse particle dust contained in the exhaust gas is accelerated by centrifugal force to reach the inner wall of the outer cylindrical portion 72, falls due to gravity, and is accommodated in the dust discharge box 77.

  The exhaust gas from which coarse particles of dust are separated and primarily purified flows through a communication port 78 formed at the upper end of the outer cylindrical portion 72 and flows into the space inside the inner cylindrical portion 73 in a tangential direction. The exhaust gas flowing into the inner cylindrical portion 73 from the communication port 78 becomes a downward swirling flow and descends along the inner cylindrical portion 73 and the conical portion 74. Fine particle dust contained in the exhaust is accelerated by centrifugal force to reach the inner walls of the inner cylindrical portion 73 and the conical portion 74, falls due to gravity, and is stored in the dust discharge box 77. When dust accumulates in the dust discharge box 77, the dust discharge box 77 is removed from the outer cylindrical portion 72, and the collected dust is disposed of.

  Exhaust gas that has been finely dusted and separated and secondarily purified is reversed in the vicinity of the lower end of the conical portion 74 to form an upward swirling flow, and ascends the inner cylindrical portion 73 and the axial center portion of the conical portion 74 so that the inner cylinder The gas is discharged to the exhaust duct 76 through 75. The exhaust discharged into the exhaust duct 76 is supplied to the suction port 81 of the exhaust circulation frame 80. The cyclone dust collector 70 according to the fourth embodiment of the present invention performs primary purification and secondary purification with a single dust collector, and therefore has a large exhaust purification capability and a small installation area.

  Next, the operation of the suction wind power sorter 101 according to the fourth embodiment of the present invention 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 in FIG. The charged raw material G is sieved in the sieve frame 111, and a small raw material falls on the belt conveyor 60. The dropped raw material is conveyed to the rear of the suction wind type sorting apparatus 101 by the belt conveyor 60. The conveyed raw material is sorted and collected behind the suction wind type sorting device 101 as a material MA having a predetermined size or less.

  A raw material having a predetermined size or more moves onto the chute member 170. Since the chute member 170 has a gentle slope, a raw material having a predetermined size or more is in a staying state or a state close to staying for a while. The exhaust discharged to the exhaust duct 76 of the cyclone dust collector 70 and the exhaust discharged to the exhaust circulation duct 186a are supplied to the suction port 81 of the exhaust circulation frame 80. Therefore, the exhaust gas supplied to the suction port 81 of the exhaust circulation frame 80 is blown upward from a hole or groove formed in the bottom surface portion 170a of the chute member 170, and a raw material having a predetermined size or more is discharged. The bottom surface 170 of the 170 is floated from the upper surface.

  The suction sorting means 120 sucks air in the vicinity of the chute member 170 from the suction port 121 a of the suction frame body 121 through the suction duct 183 by the action of the blower 184. Since the raw material having a predetermined size or more on the bottom surface portion 170 a of the chute member 170 floats from the upper surface of the bottom surface portion 170 a, the raw material is efficiently sucked by the mesh winding belt 124 and wound by the mesh winding belt 124. It moves to the left in FIG. That is, since a raw material having a predetermined size or more is floating from the upper surface of the bottom surface portion 170a, the mesh winding belt 124 is efficiently sucked even if the amount of air sucked from the suction port 121a of the suction frame 121 is small. Thus, the mesh winding belt 124 can be efficiently sucked with a small amount of energy (the outputs of the blower 184 and the blower drive motor 185 may be small).

  As shown in FIG. 8, a rubber sheet 126 that shields the front end side of the chute member 170 is suspended from the lower end of the suction sorting means 120. A metal plate is integrally incorporated in the rubber sheet 126 to increase the rigidity of the rubber sheet 126. The rubber sheet 126 can prevent the inflow of air from the side of the chute member 170 and can effectively apply the suction force from the suction port 121a to the raw material having a predetermined size or more on the chute member 170. .

  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 via the carry-out chute 175.

  In the fourth embodiment of the present invention, both the exhaust discharged to the exhaust duct 76 of the cyclone dust collector 70 and the exhaust discharged to the exhaust circulation duct 186a are directed upward of the bottom surface portion 170a of the chute member 170. However, any one of the exhaust gases may be blown out above the bottom surface 170a of the chute member 170.
