The present invention is, for example, to recover a reusable component such as plastic from the collected waste, and is installed in a recycling resource plant for promoting the reuse of resources, the weight and light weight by the wind resistance difference and specific gravity difference of the selected object. A wind sorting device for sorting by oil, and in detail, a first cavity for sorting heavy materials and light weights by injecting and supplying a sorting gas from a base end to a sorted object dropped and supplied from an inlet; and the first cavity And a heavy weight recovery part and a light weight recovery part arranged in order along the flow direction of the sorting gas, and a suction port for sucking the sorting gas supplied to the first cavity. will be.

As this kind of wind power sorting device, as illustrated in FIG. 7, the heavy material recovery chamber at one end side in which the upper side communicates with each other and the lower side is opened downwardly through the branch plate 102 in the box-shaped casing 101 ( And an inlet 105 for dividing the object into the light object recovery chamber 104 on the other end side and injecting the object to be processed into an upper portion of one end of the casing 101. An air inlet 107 is formed at the other end of the casing 101 at the lower end, while an air ejection nozzle 106 is provided at the lower portion to eject air obliquely upwardly toward the other end in the casing 101. It is proposed that the width of the water recovery chamber 104 is wider than the width of the heavy weight recovery chamber 103.

The wind power sorting device widens the width (dimensions in the horizontal direction orthogonal to the air ejection direction) of the light weight recovery chamber rather than the width of the heavy weight recovery chamber, thereby lowering the flow velocity of air in the light weight recovery chamber, thereby reducing the weight of the light weight recovery chamber. Although the length (the dimension in the horizontal direction of the air blowing direction) is short, an object of the present invention is to prevent a lightweight object such as a plastic bag, a plastic tray, or the like from household garbage from being entrained in the air suction port.

[Patent Document 1]

Japanese Patent Publication No. 2000-15183

However, according to the technique described in Patent Document 1 described above, in order to prevent light objects such as plastic bags and plastic trays from being entrained in the air suction port, the lower end is placed inside the casing above the light weight recovery chamber 104. A comb-shaped grate 108 is formed which is free end and the lower end side gradually approaches the side of the other end of the casing, or in front of the air suction port 107, the air suction port 107 side is downward. It is necessary to arrange the endless belt type net filter 109 which rotates up and down so as to move upwards, and when a long, lightweight object is wound around such a great or net filter, it is not easily detached and clogged. This causes a problem such as a decrease in the amount of suction air flow, and there is a problem that frequent maintenance such as cleaning is required.

If such a great or net filter is not provided, the same problem can be avoided because the lightweight material accompanying the sorting air causes the closing of the ventilating portion provided downstream of the air suction port and clogging of the bug filter. Even in the case where the light weight recovery chamber is wider than the heavy weight recovery chamber, it is not possible to expand it to such an extreme due to the limitation of the installation area of the apparatus, and in this case, the length of the air ejecting direction of the light weight recovery chamber. Cannot be shortened by that much.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wind turbine sorting apparatus capable of effectively recovering lightweight materials accompanying sorting gas without frequent maintenance such as cleaning, even when the installation area of the apparatus is limited in view of the above-mentioned conventional drawbacks. It is at that point.

In order to achieve the above object, the first feature configuration of the wind power sorting device according to the present invention is the sorting gas from the base end to the to-be-selected object drop-fed from the inlet as described in claim 1 of the document of the claims. A first cavity for jetting and supplying the heavy material and the light material to be sorted; A heavy weight recovery part and a light weight recovery part arranged in order along the flow direction of the sorting gas below the first cavity; And a suction port for sucking the sorting gas supplied to the first cavity, wherein the second cavity, which is wider than the first cavity, is installed in an upper space of the first cavity; The suction port is provided on the downstream side thereof, and a second lightweight object recovery part for collecting the lightweight object that is accompanied by the sorting gas and falls from the second cavity is provided.

According to the said structure, since the 2nd cavity part diameter-expanded than the said 1st cavity part is provided in the upper space of a 1st cavity part, the sorting gas introduce | transduced into a 2nd cavity part from a 1st cavity part reduces the flow velocity, and is easily lightweight. Since the water falls, and in the second cavity portion enlarged due to the decrease in the flow velocity, vertical swirl flow and local vortices occur in the vertical direction. The lightweight object is introduced, stays in the second cavity, falls, and is recovered by the second lightweight object recovery unit. Since the second cavity is disposed above the space of the first cavity, even if the installation area of the apparatus is limited, the installation area can be made compact, and the flow path of the selection gas in the second cavity can be formed long. As a result, it is possible to effectively recover the light weight accompanying the sorting gas.

The second feature configuration is, as described in claim 2, in addition to the first feature configuration, the second lightweight object recovery portion is an opening disposed at a lower end of the second cavity and a lightweight object dropped to the opening. It is comprised by the chute which guide | induces, It exists in the point where the communication part of the said 1st cavity part and the said 2nd cavity part is reduced by the said 2nd light weight collection part.

 According to the said structure, since the communicating part of a 1st cavity part and a 2nd cavity part is reduced in diameter by the 2nd light weight collect | recovery part, the injection-sorted selection gas flows in into the 2nd cavity part expanded after passing through such a shaft diameter part, The flow velocity is effectively lowered, and the flow direction of the sorting gas is shaken, causing vortices and ridges to be generated, thereby allowing the accompanying lightweight objects to fall.

The third feature configuration is that, in addition to the first or second feature configuration, as described in claim 3, the opening is disposed at the proximal end.

According to the said structure, the jetting supplying sorting gas rises along the back wall of the 2nd cavity part from the other end side on the opposite side to the base end side of a 1st cavity part, and turns the swirl flow which turns to the base end side from above the 2nd cavity part. In this case, the ridges are formed mainly at the proximal end. As a result, the lightweight object can be effectively dropped to the opening portion provided on the proximal side to be recovered.

As described in claim 4, in the fourth feature configuration, in addition to any of the first to third feature configurations, the selective gas may be added to the communicating portion of the first cavity portion and the second cavity portion. There is provided a guide plate for generating a swirl flow in the second cavity by the deflection.

According to the said structure, the sorting gas which rises along the back wall of the 2nd cavity part from the other end side of a 1st cavity part will drift to the base end side by a guide plate, and the swirl flow of a vertical direction will be formed more effectively. In addition, the light object collides with the guide plate, so that the light object can be efficiently separated from the flow of the sorting gas.

Although the screening and separating object 5 is not limited thereto, the heavy object and the light object are selectively separated and separated, for example, when the heavy object is selected from resource waste such as cans, PET, bottles, and waste glass bottles. If you do it is widely applied.

The conveying mechanism 3 is composed of a vibrating conveying mechanism having a vibrating motor 3d attached to a conveying path 3b supported by an elastic support mechanism 3a such as a spring via a connecting frame 3c. The to-be-selected object 5 put into the said conveyance path 3b by the mechanism 9 disperse | distributes evenly, and is lightweight, vibrating on the conveyance path 3b which is excited by the said vibration motor 3d. The upper part is conveyed toward the said 1st cavity part 10 while gravity weight sorting downward, and is supplied so that it may fall freely in the vertical direction from the edge part. In addition, the conveyance mechanism 3 is not limited to being comprised by the vibrating conveyance mechanism provided with the vibration motor 3d, If the conveyed object 5 is conveyed so that it may spread | distribute it evenly, another system may be employ | adopted. .

The sorting nozzle mechanism 4 is formed so that its tip portion is wider than the conveying path width of the to-be-selected object 5 by the vibrating conveying mechanism 3, and is installed below the conveying path 3b. It is provided below the 1st flat nozzle 4a and the said 1st flat nozzle 4a, and the said 1st flat nozzle (to prevent entry of lightweight objects from the front-end | tip part of the said 1st flat nozzle 4a to a base end side) It connects to the 2nd flat nozzle 4b which blows off a quantity of air less than the blowing air quantity from 4a, and forms the air barrier, and the base end side of the said 1st flat nozzle 4a and the 2nd flat nozzle 4b, respectively. Press-fit which is connected to the proximal ends of the first flat nozzle 4a and the second flat nozzle 4b via the flexible pipes 4c and 4d and the flexible pipes 4c and 4d, respectively, to supply the selected air. The sorting air provided with the blowers 8a and 8b, and supplied from the said press blower 8a. Is injected and supplied from the first flat nozzle 4a through the flexible pipe 4c. In addition, although air is used as a sorting gas here, it is also possible to select and use suitably an inert gas etc. according to a sorting object. In addition, the said 2nd flat nozzle 4b is not essential, It is provided as needed, such as the characteristic of a sorting object.

The first cavity 10 is composed of a first casing 10a formed in a rectangular cross section in a vertical direction and a space partitioned by the first casing 10a, and the first flat nozzle 4a is provided in the first flat nozzle 4a. The selected object 5 drop-fed and supplied from the conveyance mechanism 3 by the sorting air which is injected and supplied upwardly inclined toward the wall part on the back side facing the wall part of the base end side by which the said injection hole 10b was formed by this is Separation and sorting into the heavy material 5a and the light weight 5b, that is, the heavy weight 5a falls back to the heavy weight recovery part 11 as it is, and the light weight 5b recovers the heavy weight by the flow of sorting air. Falling over the partition wall 10c provided between the part 11 and the said light weight collection part 12 is carried out by the light collection part 12 and collect | recovers.

The second cavity 13 is composed of a space partitioned by the second casing 13a and the second casing 13a, the cross section of the horizontal direction being rectangular, and of the first cavity 10 The sorting air flowing upward along the rear surface is configured to guide the dust collector 7 from the suction port 15 formed thereon. As described above, the second cavity 13 has a diameter of a cross section perpendicular to the flow upward of the sorting air, that is, its cross-sectional area is perpendicular to the flow of the sorting air in the first cavity 10. Since the diameter of the cross section, i.e., the diameter of the cross section is larger than that of the cross section, the flow rate of the sorting air in the first cavity 10 is lowered. Some of the lightweight objects such as plastic bags, paper, sawdust, etc. will fall by their weight. In addition, as shown in FIG. 5, the selection air which rises from the back surface in the said 2nd cavity part 13 by the flow rate fall turns to the wall surface direction of the base end side which opposes the back surface, ie, it turns to the vertical direction. Since a vortex or a local vortex occurs, and the accompanying lump (A (A1, A2, A3)) is generated, a lightweight material accompanying the sorting air is introduced into the ridge and the inside of the second cavity 13 It stays at and falls, or the lightweight object falls by the flow of air downward.

The second cavity 13 is provided with a second lightweight object recovery part 16 that recovers lightweight objects that fall with the sorting air and fall from the second cavity 13. As shown in FIGS. 1-4, the said 2nd light weight collect | recovery part 16 is the opening part 18 arrange | positioned at the lower end of the said 2nd cavity part 13, and the said 1st from the said opening part 18. It consists of the chute 19 which inclined over the cavity part 10, and guide | induced the lightweight object which fell to the said opening part 18 to the outside, The lightweight object which fell from the chute 19 is the collection container 17 ) Is recovered.

In detail, as shown in FIG.4 (a), the said opening part 18 is the said injection hole 10b among the communicating parts 14 of the said 2nd cavity part 13 and the said 1st cavity part 10. As shown to FIG. The chute 19 is a duct-shaped structure, and is disposed so as to occupy almost half of the region on the) side, that is, the proximal end, as shown in FIGS. 2 and 4 (b). It extends from the side wall to the outside across the upper portion of the first cavity 10 from the lower side, and guides the light weight recovered from the opening 18 from the opening 18 to the recovery container 17. .

Therefore, the sorting air which rises to the 2nd cavity part 13 along the back side wall surface on the opposite side to the base end side of the 1st cavity part 10 is wall surface of the same direction as the base end side of the said 1st cavity part 10. By the swirl flow which turns to the side, it can fall effectively and collect | recovers to the opening part 18 formed directly from the bottom part mainly formed in the base end side.

Since the communication part 14 of the said 1st cavity part 10 and the said 2nd cavity part 13 is reduced in diameter by such arrangement | positioning of the 2nd light weight collect | recovery part 16, the sorting air supplied by injection is After passing through the shaft diameter part, the flow rate is lowered by flowing into the enlarged second cavity 13, and the flow direction of the sorting air is shaken, causing vortices and pools to be generated, thereby efficiently dropping the accompanying light weight. You can do it.

As shown in Fig. 1 and Fig. 3 (a), the sorting air is allowed to drift to the rear side wall portion of the communicating portion 14 so as to generate a swirl flow in the vertical direction in the second cavity portion 13. The plate-shaped guide plate 20 is provided, and the flow direction of the selection gas flowing into the second cavity 13 from the communicating portion 14 is deflected in the proximal side wall direction to the second cavity 13. In this way, the swirl flow in the vertical direction is formed, and the light object colliding with the guide plate 20 is configured to be detachable from the sorting air.

The guide plate 20 is rotatably attached to the communication portion 14 via a posture change mechanism 21 having a drive mechanism such as a fluid actuator or an electric motor, and the deflection of the selective air is changed by changing the guide posture. It is configured to adjust the direction. Therefore, by adjusting the attitude of the guide plate 20 according to the characteristics of the object to be selected 5 or the supply amount of the sorted air, it is possible to efficiently drop-collect and recover the lightweight object accompanying the sorted air.

In this way, since most of the lightweight material accompanying the flow of the sorting air is separated and removed from the second cavity 13, the lightweight material conveyed from the suction port 15 to the dust collector 7 is greatly reduced, It is not necessary to frequently maintain and maintain the dust collector (7), it is possible to significantly increase the operation rate of the wind turbine sorting device (1). Here, the diameter, or cross-sectional area, of the conduction cross section of the sorting air in the second cavity 13 is somewhat larger than the diameter, or cross-sectional area, of the flow section of the sorting air in the first cavity 10. Although the recovery rate of separation of the light objects accompanying the flow of the sorting air varies depending on whether it is set, the limit of the installation area of the wind turbine sorting device 1 changes the flow-through cross section of the sorting air in the second cavity 13. If the diameter cannot be made so large, the same effect can be obtained by setting the length of the second cavity 13 in the vertical direction to be large.

Another embodiment will be described below. In the said embodiment, although the single guide plate 20 was provided in the back side wall surface of the said communication part 14, by providing the said guide plate 20 in the space of the said communication part 14, single or multiple sheets is provided. It is also possible to effectively deflect the sorting air flowing into the second cavity 13.

Moreover, the sorting air which flows in from the said 1st cavity part 10 into the 2nd cavity part 13 of the said 2nd lightweight object collection part 16 which is unevenly distributed on the side wall side of the 1st cavity part 10 is carried out. When the chute 19 is pivoted in the horizontal direction, as shown in FIG. 6, the plate 22 which collides and detaches the light object accompanying the swirl flow in the horizontal direction is separated from the second cavity 13. You may form in a wall surface. It is also possible to divide the guide plate 20 so that the swirl flow also occurs in the horizontal direction in the second cavity 13 so that the guide plate 20 has an angle in the vertical direction.

In the above embodiment, the guide plate 20 for effectively generating the vertical swirl flow in the communication portion 14 of the first cavity portion 10 and the second cavity portion 13 is provided. As shown in FIG. 9, the configuration may not be provided with the guide plate 20. Even if it is such a structure, since the opening part 18 is arrange | positioned at the base end side of the said 2nd cavity part 13, as shown to FIG. 5 (b), from the back wall side of the said 1st cavity part 10 Swirl flow in which the sorting gas that rises along the back wall of the second cavity part 13 through the connecting portion 14 and turns to the base end side occurs, whereby a ridge is formed mainly on the base end side.

In the said embodiment, the opening area of the said opening part 18 is arrange | positioned so that it occupies about half of the area | region at the base end side of the said communication part 14, and the chute 19 is a said part from the lower part of the said opening part 18. Although it was explained that the communication portion 14 was reduced in diameter by extending outward from the side wall across the upper portion of the first cavity 10, the opening area and the position of the opening 18 are limited thereto. The opening area and position can be appropriately set as long as the lightweight object falling from the second cavity 10 can be recovered. The flow of the sorting air in the said 2nd cavity part 10 can also be adjusted with the position and opening area. At this time, the installation position of the chute 19 can also be appropriately changed, for example, may be inclined toward the proximal end side of the first cavity 10, and the first cavity (from the opening 18) can be changed. It can also be comprised by a pair of chute arrange | positioned and inclined separately in the left-right side wall direction of 10). In the latter case, it is also possible to guide the falling lightweight object from the chute 19 to the lightweight object recovery part 12.

It is needless to say that any embodiment described above is an example of the present invention, and the scope of the present invention is not limited by the specific configuration described.

As described above, according to the present invention, even if the installation area of the device is limited, it is possible to provide a wind power sorting device capable of effectively recovering the light weight accompanying the sorting gas without performing frequent maintenance such as cleaning. It became.
