Description

TECHNICAL FIELD The present invention relates to a bag-breaking sorting apparatus for destroying a garbage bag that stores various kinds of garbage to take out the garbage in the bag and sorting the garbage taken out from the bag according to the type, more specifically, household garbage. The present invention relates to a bag-breaking/sorting apparatus suitable for sorting and collecting organic waste such as raw waste from general waste such as.

In recent years, in order to use raw waste contained in general waste such as household waste as a fuel for biomass power generation, raw waste is collected from general waste. A composite device, which is a combination of a bag breaking device and a sorting device, is generally used for collecting the garbage, but it is not efficient in terms of space and energy.

As a device in which the bag breaking device and the sorting device are integrated, for example, there is a vertical rotary bag breaking sorting device presented in Patent Document 1. This device is provided with a vertical cylindrical casing, a rotating shaft arranged at a central position in the casing, and a large number of striking chains radially and multistagely attached to the rotating shaft, The rotation shaft is rotated to rotate the striking chain in a horizontal posture, and the dust bag is thrown into the casing while the casing is sucked upward, whereby the dust bag is broken and the dust is sorted.

That is, when the dust chain is thrown into the casing while the striking chain is swiveling horizontally and the casing is sucked upward, the dust bag is destroyed by the striking by the swirling striking chain and is also destroyed. Light items including dust bags are discharged to the upper side of the casing, and heavy items are discharged to the lower side of the casing.

However, such a bag-breaking sorting device has the following inconveniences when applied to the collection of organic waste such as raw garbage. First, the weight of general waste varies widely depending on the type, and organic waste such as raw garbage is not always heavy, so that the sorting efficiency is low. Secondly, the waste in the waste bag is also finely crushed due to the impact by the impact chain, so that other waste is mixed with the organic waste, which also reduces the sorting efficiency. Cause.

Also in the case of a vertical rotary type or horizontal rotary type pulverizer in which rotary blades are arranged in multiple stages in the casing instead of the striking chain, the sorting efficiency by mixing other wastes with organic wastes is also increased. Deterioration becomes a problem. By the way, there are a wide variety of types of general waste such as paper, kitchen waste, fibers, wood chips, metals, plastics, rubbers, glasses, and ceramics.

JP, 2001-327885, A

It is an object of the present invention to provide a bag-breaking sorting apparatus which is applied to sorting and recovering organic waste from general waste and which is excellent in sorting efficiency, space saving and energy saving.

In order to achieve the above object, the bag-breaking sorting device of the present invention is a vertical tubular shape in which a bag-breaking blade is rotated around a vertical axis to destroy the thrown-in garbage bag and take out the garbage in the bag. The vertical type that is disposed concentrically with the bag crushing part and below the bag crushing part, and rotates the sorting table or the stirring member on the sorting table around the vertical axis to sort out the dust taken out from the bag. It is equipped with a cylindrical selection unit,
As a rotation driving mechanism in the bag breaking unit and the sorting unit, a first rotating shaft that rotates the bag breaking blade and a second rotating shaft that rotates the agitating blade on the sorting table or the sorting table are provided at the center of the apparatus. Arranged coaxially ,
In the bag-breaking portion, a horizontal disk-shaped rotating body located below the bag-breaking blade is attached to a first rotating shaft that rotates the bag-breaking blade, and the rotating body is provided on the upper surface of the rotating body. It is provided with blower blades that form an upward airflow by rotating with the body .

In the bag-breaking sorting apparatus of the present invention, the dust bag thrown into the bag-breaking portion is broken by the bag-breaking blade rotating in the process of dropping the bag by its own weight, and the dust is taken out from the garbage bag. The trash taken out of the trash bag is sent to the lower sorting section by gravity. In the sorting section, dust is sorted by the sorting table or the rotation of the stirring blade on the sorting table . That is, the rotation of the sorting table itself, or by rotation of the stirring blades on sorting table, dust such on sorting table is stirred rotated, by a portion of which falls under the sorting plate while moving toward the outer periphery, type Selected separately. Further, in the bag-breaking part above the sorting part, as the bag-breaking blade rotates, the sending blade attached to the upper surface of the horizontal disk-shaped rotating body thereunder rotates to form an upward airflow. As a result, the bag pieces generated by the bag breakage are separated.

As described above, in the bag-breaking sorting apparatus of the present invention, from bag-breaking to sorting, gravity and two types of rotation (that is, bag-breaking rotation in the bag-breaking section and sorting rotation in the selecting section) are effective. The device is downsized and the efficiency is improved. Two types of rotation are performed by a first rotating shaft for bag breaking and a second rotating shaft for sorting, which are coaxially arranged in the center of the apparatus. For this reason, it is possible to independently set the number of revolutions suitable for bag breaking and sorting, and it is possible to reduce the size and efficiency of the device. Further, the separation efficiency of dusts is further increased by separating the bag pieces at the bag breaking portion.

In the rotary drive device, the first rotary shaft is rotatably supported in a sleeve-shaped support body fixedly installed at the center position of the device, and the second rotary shaft is sleeve-shaped and is rotatable outside the support body. It is reasonable to support. Further, both rotary shafts can be driven under the device. That is, each drive machine can be installed in the lower part of the device together with the power transmission mechanism. Therefore, the operation of loading the dust bag from the upper portion of the device is not hindered, and the drive unit and the power transmission mechanism can be easily installed.

By arranging the sorting units in a plurality of stages in the vertical direction, the sorting accuracy can be improved, and even in such a case, the increase in size of the device and the reduction in efficiency are suppressed to the minimum. When organic waste is sorted and collected from general waste, if the sorting unit is arranged in two stages, large foreign matters such as cloth and paper can be eliminated in the first stage and metal pieces, wood pieces, etc. can be eliminated in the second stage. Since small foreign matters can be eliminated, high recovery efficiency can be secured. Further, as described later, if the broken bag pieces are removed beforehand by the air pressure at the bag breaking portion, the collection efficiency can be further enhanced.

When the sorting units are arranged in multiple stages, the rotation driving mechanism for the sorting table in the upper sorting unit and the rotation driving mechanism for the stirring blade in the lower sorting unit are shared between the adjacent sorting units. Is desirable. Specifically, of the upper and lower adjacent sorting units, the sorting table in the sorting unit on the upper stage side and the stirring member in the sorting unit on the lower stage are arranged above and below the rotary support attached to the second rotating shaft. To each support. By doing so, the drive mechanism is simplified.

The bag- breaking sorting device of the present invention comprises a vertical cylindrical bag-breaking unit and a vertical cylindrical bag- like sorting unit, which are both driven by independent rotating shafts, and at the same time , the bag-breaking unit breaks the bag pieces. Since it is separated , various kinds of garbage can be efficiently sorted and collected from the garbage bag. Moreover, since an independent rotating shaft is coaxially arranged in the center of the apparatus, it is excellent in terms of space saving and energy saving. Therefore, it is suitable, for example, for sorting and recovering organic waste from general waste.

As shown in FIG. 9, the plurality of stirring blades 42 are vertical plates that are displaced in parallel with the radial lines in a parallel translational manner, and by being attached to the second rotating shaft 53 on the center side, The bottom plate is rotated toward the displacement side together with the upper stirring blades 34a and 34b and the pressing roller 35.

As shown in FIG. 1 and FIG. 2, the loading unit 60 combined with the bag breaking unit 10 is a laterally-sided cylindrical (here, rectangular) transport duct 61 connected to the charging port 12a of the crushing unit 10, A pair of transfer screws 62, 62 arranged horizontally and in parallel in the transfer duct 61, and a drive motor 63 for rotating the transfer screws 62, 62 in the biting direction shown in FIG.

The tip of the horizontal pipe portion 72 of the circulation duct 70 communicates with the upper surface of the other end of the transport duct 61 via a vertical pipe 75.

The above is the configuration of the bag-breaking sorting apparatus of the present embodiment. The operation and function of the bag-breaking sorting device are as follows.

During operation of the bag-breaking sorting apparatus, the transport screws 62, 62 in the loading section 60 at the top of the apparatus rotate in the biting direction shown in FIG. Further, in the rotary drive mechanism 50 at the center of the device, the solid first rotation shaft 52 arranged inside the fixed sleeve 51 rotates at a high speed at a predetermined rotation speed, and the sleeve arranged outside the fixed sleeve 51. The second rotating shaft 53 is rotated at a low speed at a predetermined rotation speed.

Due to the high speed rotation of the first rotating shaft 52, the bag-breaking rotary blade 15 and the sorting rotary blade 16 in the bag-breaking unit 10 rotate at a predetermined rotational speed in the same direction at high speed. Further, by the low speed rotation of the second rotating shaft 53, the sorting table 23 in the first sorting unit 20, the stirring blades 34a and 34b and the pressing roller 35 in the second sorting unit 30, and the stirring blade in the garbage collecting unit 40. 42 rotates at a predetermined rotation speed in the same direction at a low speed.

As shown in FIG. 1, when the garbage bags A are successively introduced into the one end portion of the transport duct 61 from the throw-in cylinder 64 of the throwing unit 60, those dust bags A are moved from the one end portion to the other end portion in the transport duct 61. Is conveyed to the inner casing 12 through the charging port 12a of the bag breaking unit 10.

Here, the motor 54 that drives the first rotary shaft 52 and the motor 55 that drives the second rotary shaft 53 are arranged at the bottom of the device together with the power transmission mechanism, and are connected to the lower ends of the rotary shafts. The upper end side of each rotating shaft does not project above the bag breaking portion 10. Therefore, the rotating shafts 52, 53, the motors 54, 55, and the power transmission mechanism do not interfere with the loading unit 60 on the upper part of the apparatus and do not interfere with the dust bag A loaded by the loading unit 10, so that the dust bag A can be smoothly moved. It is possible to guarantee a proper input operation.

The dust bag A thrown into the inner casing 12 of the bag-breaking portion 10 falls inside the inner casing 12 and is torn by the bag-breaking blade 15b of the rotating bag-breaking blade 15 that rotates at the bottom. At this time, the rotating body 15a contributes to the bag breaking by retaining the dust bag A on the blade, applying a centrifugal force, and transporting the dust bag A toward the bag breaking blade 15b that rotates at a high speed in the peripheral portion.

At the same time, the dust bag A tends to stay on the outer periphery of the lower portion of the inner casing 12 due to gravity and centrifugal force, but the cylindrical work holder 17 attached to the inner surface of the lower portion of the inner casing 12, particularly the lower portion thereof. The downwardly convex arc surface pushes the bag-breaking blade 15b from the upper side to the lower side, and the fin-like shape attached to the inner surface of the inner casing 12 is located below the cylindrical work holder 17. The work holder 18 pushes back from the vicinity of the inner surface toward the bag-breaking blade 15b on the center side, so that bag-breaking is efficiently performed.

The debris taken out of the debris bag A due to the bag smashing, through the annular gap 15c (FIG. 3) formed between the inner casing 12 and the inner rotating body 15a, together with the bag piece, inside the lower portion of the outer casing 11. To fall sequentially. At this time, in the lower portion of the outer casing 11, the blower blades 16b of the rotary blade 16 for selection rotate at high speed together with the disc-shaped rotating body 16a, thereby stirring the dusts on the rotating body 16a and at the same time the outer casing 11 An upward air flow B, particularly a swirl flow, is formed between the inner casing 12 and the inner casing 12. The air flow B rises while swirling between the outer casing 11 and the inner casing 12, and is discharged from the lightweight material discharge port 11a that also serves as an exhaust port. In this process, the dust collected from the dust bag A is discharged. Among them, particularly the lightweight object C, and a bag piece mainly caused by the bag breakage, is discharged to the outside of the outer casing 11 through the lightweight object outlet 11a. That is, the upward air flow B separates the bag pieces generated by the bag breakage and discharges them.

The lightweight material C discharged from the lightweight material discharge port 11a is separated from the air flow B by being decelerated by the air reservoir 73, and is discharged downward. The air flow B separated from the lightweight object C passes through the circulation duct 70, further passes through the other end of the transport duct 61 and returns to the bag crushing portion 10, and forms a downward air flow B in the inner casing 12. The downward airflow B in the inner casing 12 contributes to the formation of the upward airflow B between the outer casing 11 and the inner casing 12. In addition, exhaust air circulation by the circulation duct 70 suppresses exhaust air and odors to the outside of the device, thereby improving the environment. The horizontal disk-shaped rotating bodies 15a and 16a also prevent the upward airflow B from being formed in the inner casing 12 and contribute to the formation of the downward airflow B here, so that the breakage occurs. It contributes to the improvement of bag efficiency and the sorting efficiency of the lightweight items C.

The plurality of blower blades 16b can also be adjusted in the mounting position in the radial direction, and not only the optimum position for forming the air flow B is selected by the adjustment, but also the outer peripheral edge of the rotating body 16a is moved toward the center side. By being arranged at the displaced position, a space is formed on the rotating body 16a on the outer peripheral side of the blower blade 16b. This space facilitates the retention of dust and improves the sorting efficiency of dust.

When clogging of the dust bag A occurs in the inner casing 12, the clogging is eliminated by raising the inner casing 12 from a fixed position shown in the drawing to an upper retracted position.

Thus, in the bag-breaking unit 10, the bag-breaking process of the dust bag A is efficiently performed, and at the same time, the lightweight articles C are efficiently sorted and discharged.

The dust, which is taken out from the dust bag A and has finished sorting the lightweight items C, that is, mainly the heavy items, passes through the annular gap formed between the outer casing 11 and the rotating body 16a, and the first sorting unit 20. Flows in. At this time, dusts pass inside the centering chute 22. The centering chute 22 moves the dust toward the center side and puts it on the sorting table 23 in the first sorting unit 20. In addition, the centering chute 22 blocks the formation of the downward airflow B and contributes to the formation of the stable upward airflow B between the outer casing 11 and the inner casing 12.

The selection table 23 is a slit table and rotates at a low speed. The dusts thrown into the vicinity of the central portion of the sorting table 23 move to the outer peripheral side due to the centrifugal force caused by the rotation. Since the slits 23b formed on the selection table 23 are basically in the radial direction and have a structure opened to the outer peripheral side, small dust (metal pieces, metal pieces, A piece of wood, a piece of resin, garbage, etc., that is, the small heavy object D2 is dropped under the sorting table 23. Further, the large-sized wastes (wooden blocks, resin blocks, cloths, papers, etc.) remaining on the sorting table 23, that is, the large-sized heavy objects D1, are finally guided to the discharge scraper 24 and discharged from the heavy-weight discharge port. 21a is discharged from the apparatus.

Since the discharge scraper 24 intersects the slit 23b at a right angle or an angle in the vicinity thereof in the outer peripheral portion, the small heavy object D2 is dropped from the slit 23b and the large heavy object D1 is discharged from the heavy object outlet 21a. Facilitate. Since the discharge scraper 24 is also disposed on the downstream side of the sorting table 23 in the rotation direction, leaving a part (the space 21b) of the discharge port 21a, the large heavy object D1 on the sorting table 23 follows the discharge scraper 24. When it moves to the outer peripheral side of the sorting table 23, it is difficult to contact the downstream side edge of the discharge port 21a, so that it easily falls from the discharge port 21a, and the large heavy object D1 is accumulated on the upstream side of the discharge scraper 24. It can be prevented. Further, even when the large heavy object D1 is caught on the outer peripheral portion of the selection table 23 and is accumulated on the upstream side of the discharge scraper 24, the large heavy object D1 is allowed to enter the casing 21 again from the space 21b. This effectively prevents clogging of the discharge scraper 24 on the upstream side.

The small heavy object D2 that has dropped to the lower side of the sorting table 23 drops onto the sorting table 33 in the second sorting unit 30. On the selection table 33, the stirring blades 34a and 34b and the pressing roller 35, which are radially arranged, are rotating. By the rotation of the stirring blades 34a and 34b, the small heavy object D2 on the selection table 33 is rotationally agitated and moved to the outer peripheral side, and in this process, the small heavy object D2 is crushed by the pressing roller 35, so that the small garbage D2 of the small object Since E is a viscous substance, it efficiently drops to the lower side of the selection table 33, and solids (metal pieces, wood pieces, resin pieces, etc.) remain on the selection table 33 and are discharged from the heavy object discharge port 31a to the outside of the apparatus. To be done. In addition, the stirring blades 34a and 34b have a configuration in which the inner peripheral portion and the outer peripheral portion are combined, and the former contributes mainly to stirring and the latter mainly contributes to discharge, so that the selection efficiency is improved.

The raw garbage E dropped to the lower side of the sorting table 33 is collected in the raw garbage collecting section 40, and is gradually moved to the outer peripheral side by the rotation of the stirring blade 42, and finally from the raw garbage discharge port 41a to the outside of the apparatus. Is discharged to and collected.

Thus, the bag-breaking and sorting apparatus of the present embodiment efficiently sorts and collects organic waste such as raw waste from the packed domestic waste such as household waste.

In the bag-breaking sorting apparatus according to the present embodiment, the bag-breaking and the sorting are independently performed by different mechanisms (the bag-breaking unit 10 and the sorting units 20 and 30), so that the respective efficiency is high. Since the apparatus is a vertical type, and the bag breaking unit 10 and the sorting units 20 and 30 are directly connected to each other, and gravity is used to convey dusts, the processing efficiency is further improved. Since the device is a vertical type and the rotary drive mechanism 50 is centrally arranged in the central part of the device, the device can be downsized.

Since the bag breaking unit 10 not only breaks the bag but also sorts the lightweight objects C, the burden on the sorting units 20 and 30 is reduced, and as a result, the sorting efficiency is improved. Since bag breaking is performed by high speed rotation of the bag breaking blade 15b, the efficiency is high. Since the rotary blade 16 for sorting, in which the rotary drive mechanism 50 is commonly used with the rotary blade 15 for bag breaking, is used for sorting the lightweight items C, the efficiency of sorting is high, and the size of the apparatus is reduced, and the structure of the apparatus is also increased. Simplification of is realized.

In the bag-breaking portion 10, the outer casing 11 and the inner casing 12 are combined so that the inside of the inner casing 12 serves as a bag-breaking space and the space between the outer casing 11 and the inner casing 12 serves as a carry-out space for the lightweight object C. That is, bag breaking and transportation are performed in independent spaces. In addition, a downward air flow B is formed in the bag breaking space, and an upward air flow B is formed in the carry-out space. From these points as well, the bag breaking efficiency and the sorting efficiency of the lightweight items C are improved.

In addition, in the bag-breaking portion 10, the bag-breaking rotary blade 15 performs the bag-breaking independently, and the light-weight objects B are selected by the selecting rotary blade 16 independently. Become. The rotating blade 15 for bag breaking uses the rotating body 15a to support the bag breaking blade 15b, and the rotating blade 16 for sorting uses the rotating body 16a to support the blower blade 16b. These rotating bodies 15a and 16a are horizontal disc-shaped and prevent the upward airflow B from being formed in the inner casing 12. Therefore, the rotating bodies 15a and 16a also have the outer casing 11 and the inner casing. It contributes to the formation of an upward air flow B with the air conditioner 12.

For the formation of the upward airflow B between the outer casing 11 and the inner casing 12, a circulation duct arranged from the lightweight discharge port 11a also serving as the exhaust port of the outer casing 11 to the input port 12a of the inner casing 12. As described above, 70 contributes.

On the other hand, in the sorting of heavy objects, the first sorting section 20 and the second sorting section 30 perform the processing in two stages, so the sorting efficiency is particularly high. Nevertheless, the respective casings 21 and 31 are directly connected to each other in the longitudinal direction in a flat cylindrical shape, and the rotary support body 32 supports the driving of the sorting table 23 in the first sorting unit 20 and the second sorting unit. In 30, the supporting and driving of the stirring blades 34a and 34b as the stirring member and the pressing roller 35 are controlled respectively, so that the enlargement of the apparatus is effectively suppressed.

In addition, in the first sorting unit 20, since the sorting table 23 is a rotary slit table and the individual slits 23b are opened to the outer peripheral side, the sorting efficiency of the large heavy object D1 is high. Moreover, since the individual slits 23b are inclined in the rotation direction of the selection table 23 with respect to the radial line when the center side is viewed from the outer peripheral side, the discharge scraper 24 is formed with the slits 23b in the outer peripheral portion of the selection table 23. They intersect at right angles or angles near them. This also improves the sorting efficiency of the large heavy object D1.

Further, in the second sorting unit 30, the pressing blades 35 are used as stirring members in addition to the stirring blades 34a and 34b, and dust is stirred and pressed on the sorting table 33, so that the small heavy objects D2 and raw materials are generated. The dust E is efficiently sorted. Moreover, the stirring blades 34a, 34b are a combination of the inner blade for the inner peripheral portion and the outer blade for the outer peripheral portion, which also contributes to the improvement of the selection efficiency.

The bag-breaking sorting device according to the present embodiment is a garbage collecting device, but the vertical tubular sorting units 20 and 30 are arranged concentrically below the vertical tubular bag-breaking unit 10, and the respective rotary shafts are arranged. The bag-breaking selection structure in which the (first rotating shaft 52 and the second rotating shaft 53) are coaxially arranged in the center of the apparatus is, for example, a mixture of plastic container packaging waste and cans, bottles, PET bottles, etc., which are specified in the Container and Packaging Recycling Law. It can also be applied as a sorting device for garbage, garbage collected at stations or trains, a heavy/light sorting device, and a sorting device for unsuitable substances and contraindicated substances.

Further, the structure of the bag-breaking portion 10 in the bag-breaking sorting apparatus according to the present embodiment, that is, the vertical casing-shaped outer casing 11 and the inner casing 12 are combined, and the bag-breaking rotary blade 15 and the sorting rotary blade 16 are combined therewith. In combination, the bag-breaking structure that uses wind force to selectively remove the bag-breaking bag and the light-weight item C is not suitable for a heavy-weight sorting device for plastic container-wrapping waste and paper container-wrapping waste specified in the Container and Packaging Recycling Law. It is also applicable as a device for removing things and contraindications.

Similarly, the configuration of the sorting units 20 and 30 in the bag-breaking sorting apparatus according to the present embodiment, that is, the vertical tubular casings 21 and 31 together with the screening tables 23 and 33 having the screen structure also serving as the bottom plates thereof are vertically arranged in a plurality of stages.
