[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wind power sorter.
[0002]
[Prior art]
In order to process a bag filled with contents such as a garbage bag, it is necessary to break the bag in advance to separate the contents (sorted garbage, etc.) from the bag.
Conventionally, various bag breaking machines, bag breaking machines, etc. have been developed that automatically break the bags of the bag-packed body and then further separate the contents and the bags (for example, Patent Document 1 and (See Patent Document 2 etc.).
In these bag breaking machines and bag breaking machines, the separated contents are sent to a dedicated processing line by an appropriate conveying device such as a conveyor, and at this time, the contents can be made not to be mixed with bags. In addition, it is said that there is an advantage that a sorting operation for environmental measures or the like (an operation of removing a plastic bag from the contents) is omitted.
[0003]
In addition, regarding the bag after separation, when the contents and the bag are dropped from a predetermined height, only the bag is lifted and sucked out by suction (Patent Document 1) or by blowing high-speed air current A method in which a bag is attached to the outer peripheral surface of a bag breaking wheel for a while and a bag collecting chute is provided at a position where high-speed air current does not reach, thereby allowing the bag to fall naturally onto this collecting chute (Patent Document 2) ) Etc. are being studied.

[Problems to be solved by the invention]
In conventional bag breakers and breaker bags, it is possible that the separated contents are not mixed with bags, but on the other hand, the separated bags have gaps such as the blades and sieves on the device side when the bags are broken. There were a lot of small contents that passed through.
For this reason, it is necessary to perform a sorting operation for further removing the contents from the separated bag, which requires a cumbersome and inefficient manual operation. In addition, the work cost is increased and the length and complexity of the equipment are increased.
[0006]
The present invention has been made in view of the above circumstances, and after the bag is broken with a bag breaking machine, a bag breaking machine or the like, the bag can be taken out easily and reliably, while the structure is simple and compact, It is an object of the present invention to provide a wind power sorting device that can make a taken-out bag almost free from mixing.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has taken the following measures.
First, a sorting wind tunnel 16 having a case structure that accepts floating material and non-floating material in a mixed state from the receiving port 20 and takes out floating material from the upper outlet 22, and air is blown out from the inner bottom side of the sorting wind channel 16. Then, the first stage blowing device 17 that blows up the received floating material and sends it to the upper outlet 22, and the latter stage that blows air between the first stage blowing device 17 and the upper outlet 22 so as to blow the additional wind on the floating material A blowing device 18 is provided;
The main air from the first stage blowing device 17 to the upper outlet 22, the secondary air from the rear stage blowing device 18 to the upper outlet 22, and the floating material that drops off from the main air and the sub air around the rear stage blowing device 18. And air guide means for forming the circulating air as main air and sub air is provided in the sorting wind tunnel 16,
The air guide means has a current plate 28 inclined obliquely upward from the lower air outlet 23 of the first stage blower device 17 to the upper air jet port 25 of the rear stage blower device 18 below the rear stage blower device 18. 28 guides the main air upward so as to pass the upper side of the upper air outlet 25 and sucks the circulating air from the lower side by the ejector action.
[0008]
As a result, the floating material can be selected from the mixture of floating material and non-floating material by blowing air in one or two stages with the blown air, so that the floating material alone can be easily and reliably selected. In addition, even floating material that could not be fed by blowing up with main air and sub air once can be circulated and tried any number of times, so that sorting and feeding of floating material can be ensured.
Second, the sorting wind tunnel 16 is formed with an upper guide surface 16b that is applied to the air blown from the first stage blowing device 17 and bent toward the upper outlet 22 side, so that the upper guide surface 16b may drop from the bent air. In order to blow a tailwind on the floating material But It is located below the bending air.
[0009]
As a result, it is possible to efficiently blow the tailwind of the rear-stage blowing device 18 to the floating material that could not be delivered to the upper outlet 22 only with the air ejected from the first-stage blowing device 17, and the selection of only the floating material can be performed more effectively. Easy and reliable.
Third, the air guiding means As An upper inner wall surface 16c that is formed below the upper outlet 22 and guides the circulating air downward, and is inclined downward from the lower portion of the upper inner wall surface 16c toward the lower air outlet 23 to circulate the air. A lower guide member 16d that guides the lower air outlet 25 to the lower side and joins the main air from the lower air outlet 23 further Is provided.
[0010]
Thus, even floating material that could not be fed by blowing up with main air and sub air once can be circulated and tried any number of times, and sorting and feeding of floating material can be ensured.
Fourthly, the upper outlet 22 of the sorting wind tunnel 16 is connected to the separation device 3 for separating the floating material from the air via the transfer pipe 10, and this separation device 3 is used for supplying the air after separation of the floating material. The sorting wind tunnel 16 is connected to the first stage blowing device 17 and the rear stage blowing device 18 via the trachea 13 and the branch pipe 24.
[0011]
As a result, air used for sorting and separation can be circulated and used in the bag-breaking processing system having the sorting wind tunnel 16 and the separation device 3, and the sorting efficiency, separation efficiency, air blowing efficiency, etc. can be improved, and dust outside the system can be used. Leakage can be reduced.
Fifthly, the sorting wind tunnel 16 is connected to the receiving port 20 with a bag breaking device 4 that breaks the bag-packed body into the contents and the bags, and is connected to the inner bottom portion 16a of the sorting wind tunnel 16. Is connected to an unloading device 5 for non-floating material through a lower outlet 21.
As a result, the floating material can be extracted from the mixture of the floating material and the non-floating material, and at the same time, the non-floating material can be efficiently and reliably extracted.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 thru | or FIG. 7 has shown 1st Embodiment of the bag breakage processing system 1 constructed | assembled using the wind power sorter 2 based on this invention.

It is connected to the wind power sorter 2.
[0014]
That is, in the bag breaking treatment system 1, when the air suction device 12 generates an air suction action, the exhaust flow generated from the air suction device 12 is first supplied from the vent pipe 13 to the wind power sorting device 2, Further, a circulation flow is formed in which the wind sorting device 2 reaches the separation device 3 via the transfer tube 10 and further returns from the separation device 3 to the air suction device 12 of the suction source via the suction tube 11. Will do.
In the bag-breaking processing system 1, the bag-breaking device 4 is set to the bag-filling device input position, and the bag-breaking device 4 breaks the bag of the bag-packing material that has been input and distributes the contents. Let
[0015]
The bag breaking device 4 is provided at its lower part with a delivery conveyor 15 that feeds the broken bag and the contents in a mixed state. For example, a belt conveyor (or a screw conveyor or the like) is used for the delivery conveyor 15.
The wind sorting device 2 is provided on the delivery end side of the delivery conveyor 15 so that bags and contents are received from the bag breaking device 4 via the delivery conveyor 15.
[0016]
As shown in FIGS. 3 and 4, the wind power sorting device 2 includes a sorting wind tunnel 16, a first stage blowing device 17, and a rear stage blowing device 18, and the sorting wind tunnel 16 has a hollow inside. It has a case structure.
The sorting wind tunnel 16 is provided with a receiving port 20 that communicates with the delivery end of the delivery conveyor 15 on one end side (each left side in FIGS. 1 to 4).
The height at which the receiving port 20 is provided in the sorting wind tunnel 16 is substantially intermediate, so that the inner bottom portion 16a directed inward from the receiving port 20 is inclined downward.
[0017]
The sorting wind tunnel 16 is provided with a lower outlet 21 following the inner bottom portion 16a. An unloading device 5 constituted by a belt belt conveyor (or a screw conveyor) is connected to the lower outlet 21 in such an arrangement that the loading end is exposed. Further, an upper inner wall surface 16c is formed on the lower side of the upper outlet 22, and a lower guide member 16d inclined downward from the lower portion of the upper inner wall surface 16c toward the inner bottom portion 16a is provided. The guide member 16d guides the flow of circulating air described later.
Further, in the sorting wind tunnel 16, an upper outlet 22 is provided obliquely upward on the side opposite to the receiving port 20 (each right side in FIGS. 1 to 4). The transfer pipe 10 described above is connected to the upper outlet 22.
[0018]
The first stage blowing device 17 is provided below the inner bottom portion 16a of the sorting wind tunnel 16 that is slid down after the bagging is broken, and is capable of jetting air obliquely upward (or upward). The air ejected from the first stage blowing device 17 uses the exhaust flow generated in the air suction device 12.
That is, as shown in FIGS. 1 and 2, the lower air jet port in which the tip of the ventilation pipe 13 connecting the air suction device 12 and the wind sorting device 2 is embedded in the inner bottom portion 16 a of the sorting wind tunnel 16. By connecting to 23, this first stage blowing device 17 is configured.
[0019]
When comparing the contents of the bag fed into the sorting wind tunnel 16 with the contents, the bag is usually made of a thin plastic, so it is lighter than the contents and has a large surface area. Therefore, when these bags and contents are in a mixed state, when a wind (air flow) having a predetermined air volume and pressure is blown onto them, the bags will rise and the contents will not dance (initially If it is at a height, it will fall). Therefore, hereinafter, the bag is referred to as “floating material” and the contents are referred to as “non-floating material”.
[0020]
When the first-stage blowing device 17 ejects air from the lower air outlet 23, the floating material is blown up to a higher position in the wind, whereas the non-floating material is not blown in the wind, It falls to the outlet 21 and is discharged from the lower outlet 21 to the carry-out device 5.
The latter stage blowing device 18 blows air to the floating material blown up by the air blown from the first stage blowing device 17 so as to apply additional wind from a predetermined height position. As with the first stage blowing device 17, the exhaust flow generated in the air suction device 12 is also used for the air ejected from the latter stage blowing device 18.
[0021]
That is, as shown in FIG. 1 and FIG. 2, a branch pipe 24 is provided from the middle of the ventilation pipe 13 connecting the air suction device 12 and the wind power sorting apparatus 2. By connecting to the upper air outlet 25 (see FIG. 3) provided at a position higher than the lower air outlet 23 of the first stage blowing device 17, the latter stage blowing device 18 is configured.
The first stage blowing device 17 and / or the latter stage blowing device 18 may be provided with a blower, or may be provided with a unique air pipe from a separately installed compressed air pump.
[0022]
The air blowing of the first stage blowing device 17 may be set so as to be directed to the upper outlet 22, but is directed to the upper guide surface 16 b of the sorting wind tunnel 16 inclined upward toward the upper outlet 22, An upper air outlet 25 is disposed below the upper guide surface 16b with an air circulation space. The air jet from the upper air outlet 25 is directed to the upper outlet 22, the upper inner wall surface 16 c of the sorting wind tunnel 16 below the upper outlet 22, the lower guide member 16 d, and the like.
Further, a guide plate 29 is provided on the upper inner surface of the sorting wind tunnel 16 so that the air of the first stage blowing device 17 can be guided to the upper guide surface 16b. A rectifying plate 28 that is inclined obliquely upward is provided to the air outlet 25, and guides the jet stream-like air of the first stage blowing device 17 upward so as to pass above the upper air outlet 25, and by ejector action. Air is sucked from the lower side of the current plate 28.
[0023]
Accordingly, the jet air (main air) jetted from the lower air jet port 23 of the first stage blower device 17 rises while being guided by the rectifying plate 28 and the guide plate 29, hits the upper guide surface 16b inclined upward, and the upper outlet 22 Is bent to the side and sent from the upper outlet 22 to the transfer tube 10.
Most of the floating material that has been swollen from the inner bottom portion 16a of the sorting wind tunnel 16 by the main air is swept by the air (sub-air) ejected from the upper air ejection port 25 when passing over the upper air ejection port 25. Raised and boosted, it is reliably sent to the transfer tube 10.
[0024]
The floating material is sent to the transfer pipe 10 together with the main air. However, the floating material that has not been able to get on the rising air well and does not reach the upper outlet 22 will fall into the secondary air after passing through the upper air outlet 25. Assisted and sent to the transfer tube 10 under the force of soaring.
The floating material that falls off with the help of the sub-air is swollen again to the transfer pipe 10 by the circulating air that circulates. Part of the main air and the sub air generates a downward flow from the top to the bottom due to the shape action of the upper guide surface 16b, the upper inner wall surface 16c, the lower guide member 16d, and the like. When reaching the lower side, the main air guided by the rectifying plate 28 receives the ejector action and merges with the main air, thereby generating circulating air surrounding the upper air outlet 25 and the rectifying plate 28, The floating material is recirculated by the circulating air until it is sent to the transfer pipe 10.
[0025]
This is particularly useful when solids, liquids, etc. are attached to the floating material and are heavy, and the attached solids, liquids, etc. are removed by reflux in the sorting wind tunnel 16. The floating material is fed to the transfer pipe 10 when solids, liquids, etc. are removed and become light.
The upper guide surface 16b, the upper inner wall surface 16c, the lower guide member 16d, the rectifying plate 28 and the guide plate 29, and the lower air outlet 23 and the upper air outlet 25 for forming circulating air with the main air and the sub air are provided. The air guide means is constituted by the air ejection direction and the like, and by making the positional relationship between the rectifying plate 28 and the lower guide member 16d relative to the main air appropriate, the generation of circulating air by the ejector action can be made more efficient. it can.
[0026]
The upper guide surface 16b from the guide plate 29 and the lower guide member 16d from the upper inner wall surface 16c are formed in an arc shape to reduce air flow loss, the lower guide member 16d, the current plate 28, the guide plate. The inclination angle such as 29 may be freely changed.
In addition, the lower air outlet 23 is directed toward the upper outlet 22 and the upper air outlet 23
The part air outlet 25 is arranged, all of the air ejected from the upper air outlet 25 is directed to the upper outlet 22, and both the main air and the sub air are used as air for raising the floating material toward the upper outlet 22. However, it can also be configured to give the floating material a powerful lifting force in two stages.
[0027]
In the transfer pipe 10, the air suction device 12 causes an air flow from the wind power sorting device 2 to the separation device 3, so that the floating material is forcibly pneumatically transported in the transfer tube 10. .
6 and 7, the separation device 3 has a casing 43 disposed in a square tube-shaped (or may be cylindrical) device case 3 </ b> A, and a screw conveyor 40 is disposed in the casing 43.
The screw conveyor 40 is rotatably held in the apparatus case 3A with the rotary shaft 41 facing up and down, and is rotationally driven by a motor 42 provided at the upper end of the rotary shaft 41. . The rotation direction of the motor 42 is a direction that causes the screw conveyor 40 to have a downward feeding action.
[0028]
The casing 43 surrounds the entire periphery of the screw blade end of the screw conveyor 40, and has a cylindrical shape. And the front-end | tip of the said transfer pipe 10 is connected with respect to this casing 43 from the side.
The direction in which the floating material is fed by the screw conveyor 40 intersects the direction in which the floating material is sent toward the screw conveyor 40 by the transfer pipe 10, that is, the direction in which the floating material is sent by the transfer pipe 10 and the screw conveyor 40. The crossing angle is orthogonal in a side view.
[0029]
Further, when the connecting portion between the casing 43 and the tip of the transfer pipe 10 is viewed in a plan view, the transfer pipe 10 is connected in a tangential direction to the cylindrical casing 43 and an arcuate guide plate 11A is attached, Connected in the form.
Therefore, the floating material pneumatically transported in the transfer pipe 10 is directly blown onto the side surface of the screw conveyor 40 along the circumferential direction along with the air flow, and adheres to the upper and lower surfaces of the screw blades of the screw conveyor 40. It will get caught. At this time, entrainment of the floating material from the transfer pipe 10 to the screw conveyor 40 (intrusion into the casing 43) is performed very smoothly.
[0030]
The casing 43 is provided with an exhaust portion 44 that extends about a half circumference in the circumferential direction. The exhaust part 44 is connected to the air suction device 12 via the suction pipe 11.
The exhaust portion 44 has a structure in which an opening is formed in a part of the casing 43 and an arc-shaped perforated plate (filter material) 45 made of, for example, a punching metal or a net material is fitted into the opening. This structure allows air flow but not floating material.
The exhaust portion 44 is in a different position (substantially opposite position) in the circumferential direction of the screw conveyor 40 as viewed from the portion where the transfer pipe 10 is connected, and is substantially in the same position in the axial direction along the rotary shaft 41. Is provided.
[0031]
In the illustrated example, the transfer pipe 10 is spirally connected to the casing 43 as described above, whereas the exhaust part 44 sandwiches the connecting part of the transfer pipe 10 and the rotating shaft 41 of the screw conveyor 40. However, it is positioned as facing directly on the facing side.
Accordingly, when an air flow containing floating material is blown onto the screw conveyor 40 by the transfer pipe 10, the floating material is left on the screw conveyor 40 side, and only air that does not contain floating material passes through the exhaust part 44. The air is exhausted from the casing 43 into the apparatus case 3A.
[0032]
In this way, the floating material and the air flow are separated, and the screw conveyor 40 is rotationally operated, whereby the floating material is pushed and conveyed downward along the screw conveyor 40.
The suction tube 11 communicating between the exhaust part 44 and the air suction device 12 is attached to the device case 3A of the separation device 3 via a hinge portion 46, and is simultaneously attached to the device case 3A and the suction tube 11. It can be freely changed to a state of being released at the same time as the state of joining. Thereby, cleaning and maintenance in the separation device 3 can be performed easily and quickly.
[0033]
Further, in the separating device 3, a compression part 40a is formed in the lower part of the screw conveyor 40, and this compression part 40a is located on the front side in the feed direction (in FIG. 6) from the position where the connecting portion of the transfer pipe 10 is provided. The screw area is narrowed (or the screw pitch is shortened).
The casing 43 is extended so as to surround the periphery of the screw blade end even in the portion where the screw area of the screw conveyor 40 is reduced in this way (or the portion where the screw pitch is reduced). As a matter of course, the casing 43 has a tapered taper shape in a portion where the screw area of the screw conveyor 40 is narrowed.
[0034]
Such a structure of the screw conveyor 40 and the casing 43 constitutes a solidification discharge device 8 for solidifying the floating material by compression. In the compression section 40a of the screw conveyor 40, the floating material gradually slows the conveying speed. As a result, it is gradually pushed and compressed.
A squeezing device 50 is provided at the tip of the solidification discharge device 8 (the lower end of the screw conveyor 40). In this throttle device 50, a plurality of bowl-shaped throttle pieces 51 that are obtained when a cylindrical body is cut radially along its radial direction are arranged circumferentially along the inner side of the extended end of the casing 41. These are arranged and thereby formed as the inner diameter movable outlet 52.
[0035]
Each throttle piece 51 is loaded with a spring (not shown) in a spring case 53 provided so as to project outward from the casing 41, and is pressed by the spring to be urged radially inward. .
For this reason, in the expansion device 50, when the solidified floating material passes through the inner diameter movable outlet 52, an optimum opening amount is held according to the amount of the floating material, the solidification density, and the like. Therefore, it is possible to prevent problems such as clogging at this portion due to changes in the amount of floating material and solidification density.
[0036]
As described above in detail, when the entire processing flow of the bag-breaking processing system 1 is rewritten, a bag-packed body filled with contents such as a garbage bag is loaded into the bag-breaking device 4. The bag-packed body is broken by the bag-breaking device 4, and the broken bag (floating material) and the contents (non-floating material) are mixed with each other and scattered through the delivery conveyor 15. It is sent to the sorting device 2.
When the air suction device 12 is operated, an exhaust flow is generated together with the air suction action. This exhaust flow is guided to the wind power sorter 2 through the vent pipe 13 and ejected from the lower air jet 23 of the first stage blower 17 in the sorter wind tunnel 16. Further, the gas is also ejected from the upper air ejection port 25 of the rear blowing device 18 through the branch pipe 24 branched from the vent pipe 13.
[0037]
As a result, in the sorting wind tunnel 16, the floating material is first blown up to a predetermined height by the air ejected from the first stage blowing device 17 and then raised to a higher position by the air ejected from the second stage blowing device 18. Then, it is guided to the upper outlet 22. The floating material that has not reached the upper outlet 22 by one rise is circulated in the sorting wind tunnel 16 and blown up until it exits to the transfer pipe 10.
Then, the floating material is pneumatically transported from the upper outlet 22 to the separation device 3 through the transfer pipe 10 by the flow of the jet air from the first stage blower 17 and the latter stage blower 18.
[0038]
On the other hand, the non-floating material falls from the lower outlet 21 of the sorting wind tunnel 16 to the unloading device 5 and is discharged by the unloading device 5.
The floating material that has been pneumatically transported from the transfer pipe 10 to the separation device 3 as described above is blown directly onto the side surface of the screw conveyor 40 together with the air flow, so that the floating material remains on the screw conveyor 40 side. The air that is not included is exhausted from the casing 43 via the exhaust part 44, and is returned to the original air suction device 12 via the suction pipe 11. At this time, excess air is released from the exhaust pipe 6 through the dust collector 7 into the atmosphere.
[0039]
After the floating material and the air flow are separated in this manner, the floating material is transported along the rotating screw conveyor 40 in the separation device 3 and is compressed and solidified by the solidification discharge device 8. Then, it is discharged through the expansion device 50.
FIGS. 8 to 11 show another separation device 200 and a solidification discharge device 201 that can be replaced with the separation device 3 of the bag breaking treatment system 1, and other parts of the bag breaking treatment system 1 such as the wind sorting device 2. The relationship with the configuration is substantially the same as in the above embodiment.
The separator 200 shown in FIGS. 10 and 11 is rotatable with respect to a casing 203 in which a spiral passage 202 is formed, with a cage roller 204 and a stripping roller 205 circumscribing each other in the spiral passage 202. It is stored.
[0040]
The spiral passage 202 has a primary side (the right side in FIG. 10) connected to the transfer pipe 10, and is connected to the air suction device 12 in a midway portion before reaching the stripping roller 205 in the spiral passage 202. A suction pipe 11 is connected in communication.
The stripping roller 205 is provided with a plurality of flexible blades 206 in a radial pattern, and a recovery pipe 207 is connected to a portion past the stripping roller 205. The stripping roller 205 can be rotated together with the cage roller 204 in the same direction via the winding transmission means 208 and is driven by the motor 209.
[0041]
Therefore, in this separating apparatus 200, the floating material moves along with the air in the spiral passage 202 while being entrained on the outer peripheral surface of the cage roller 204 by the rotation of the cage roller 204 and the stripping roller 205. The suction material is sucked into the suction tube 11, and the floating material is scraped off to the recovery tube 207 by the flexible blade 206 of the stripping roller 205.
The separation device 200 shown in the figure is provided with an auxiliary conveying means 210. The auxiliary conveying means 210 is for preventing the stripping roller 205 from being damaged due to the entanglement of the floating material. The auxiliary conveying means 210 blows an air flow Z onto the floating material scraped off by the stripping roller 205 to Is forcibly dropped into the recovery pipe 207.
[0042]
The air flow Z used in the auxiliary transport unit 210 is generated by the auxiliary suction fan 211. For this reason, the recovery pipe 207 includes a wind guide pipe 212 that guides the air flow Z from the auxiliary suction fan 211 to the stripping roller 205. A wind collecting pipe 213 that guides exhaust gas from the downstream side of the collection pipe 207 to the auxiliary suction fan 211 is connected.
The solidification discharge device 201 is installed so as to receive the floating material via the recovery pipe 207 connected to the separation device 200.
The present invention is not limited to the above-described embodiments, and can be appropriately changed according to the embodiments.
[0043]
【The invention's effect】
As is clear from the above description, the wind power sorting apparatus according to the present invention sorts floating material from the mixture of floating material and non-floating material with non-floating material by blowing up the floating material in one or two stages with jet air. This makes it possible to easily and reliably sort only floating materials.
