It comprises a blower 44 and a waste sorting / accommodating section 46.
[0036]
The first air supply chamber 41 is formed with an injection portion 42 that injects air upward in the direction of the waste discharged from the waste discharge port of the vibration conveyor 1.
[0037]
The pipe 43 is provided with an adjustment valve 45 for adjusting the amount of air supplied from the blower 44.
[0038]
The waste sorting container 46 is composed of a non-combustible material container 47 disposed on the dust discharge port side of the vibration conveyor 1, and a combustible material container 49 disposed in parallel with the non-combustible material container 47 and the separation plate 48 therebetween. Conveyors 47 a and 49 a are disposed at the bottom of the incombustible material accommodating portion 47 and the combustible material accommodating portion 49.
[0039]
The wind power sorter 4 configured in this way supplies air to the first air supply chamber 41 via the regulating valve 45 by the blower 44, and injects the air upward from the injection unit 42. Garbage discharged from the vibration conveyor 1 by the air flow caused by jetting is sorted into combustible and non-combustible materials.

[0044]
Next, the operation of the thus configured garbage sorting apparatus will be described.
[0045]
First, the garbage bag is put into the hopper 13. The thrown-in waste is carried into the vibrating conveyor 1 from below the hopper 13 and conveyed to the waste discharge port by the vibration of the vibrating conveyor 1. At the time of conveyance by the vibration conveyor 1, the upper blade 22 of the bag breaking device 2 rotates from the uppermost position to the lowermost position, so that the upper blade 22 pierces into the garbage bag, and the upper blade 22 moves in the conveyance direction. In cooperation with the lower blade 21, the garbage bag is broken.
[0046]
The garbage thus broken and taken out from the garbage bag is conveyed to the garbage discharge port by the vibration conveyor 1 and is loosened by the air flow ejected from the through hole 51 to the upper side of the conveyance passage 12 before the dust discharge port. While being discharged from the waste outlet.
[0047]
The discharged garbage is lightly combusted by the air flow ejected from the ejection unit 42 and is stored in the combustible material storage unit 49, and the heavy incombustible material falls into the incombustible material storage unit 47 and is transported respectively. It is conveyed to an appropriate place by the conveyors 49a and 47a.
[0048]
The above-described waste sorting apparatus puts garbage into the vibrating conveyor 1 together with garbage bags, and after the bag breaker 2 breaks the bag on the vibrating conveyor 1, the wind sorting apparatus 4 sorts into combustible and incombustible materials. Therefore, the apparatus can be made compact without separately providing a bag breaking apparatus on the upstream side as in the prior art. Moreover, the garbage broken by the vibration of the vibrating conveyor 1 is loosened, and the dust is further loosened by the air flow ejected from the through-hole 51 provided on the waste discharge port side, thereby improving the sorting accuracy by the wind power sorting device 4. Can be made.
[0049]
In this example, the through hole 51 is formed with a predetermined width in the vicinity of the dust discharge port of the transport passage 12, but the through hole 51 may be formed in the entire transport passage 12.
[0050]
4 and 5 show the waste sorting apparatus according to claims 2 and 3. FIG. In addition, the same code | symbol is attached | subjected to the member similar to the waste sorter mentioned above, and description is abbreviate | omitted.
[0051]
A scoop body 7 is provided at the discharge end of the vibration conveyor 1.
[0052]
The rake body 7 is formed in a comb shape in which a plurality of rods 72 are extended from the main body 71, and the rods 72 are arranged to extend in the same direction as the conveying direction of the vibrating conveyor 1. An end rod 72 is extended to the vibration conveyor 1 side and connected to the vibration conveyor 1. Therefore, the scoop body 7 is disposed substantially horizontally with a predetermined distance from the discharge end of the vibration conveyor 1.
[0053]
The interval H between the adjacent rods 72 is set so that an aluminum can can pass therethrough and combustibles ride on the rods 72 and are conveyed in the same direction by vibration transmitted from the vibrating conveyor 1. .
[0054]
A recovery hopper that forms the incombustible material accommodating portion 47 is installed below the scoop body 7, and a combustible material accommodating portion 49 is formed in front of the incombustible material accommodating portion 47 where the tip of the scoop body 7 faces. A collection hopper is installed.
[0055]
Further, a guide plate 75 is disposed on the upper part of the dust sorting and accommodating portion 46 above the tip of the scoop body 7. The guide plate 75 is for guiding the combustible material blown upward by the air flow injected from the injection unit 42 to the scooping body 7 or the combustible collection unit 49.
[0056]
A through hole 76 is formed on the opposite side of the guide plate 75, and the through hole 76 communicates with a dust collector (not shown).
[0057]
In this garbage sorting apparatus, the garbage may be carried into the vibrating conveyor 1 in a state where the bag is broken in advance. In this case, the above-described bag breaking apparatus is not necessary, but here, the same bag breaking apparatus as described above. Is described as being provided on the vibration conveyor 1.
[0058]
Next, the operation of the garbage sorting apparatus configured as described above will be described.
[0059]
In addition, about the operation | movement of the bag breaking apparatus at the time of conveyance by the vibration conveyor 1 and the vibration conveyor 1, it is the same as that of the waste sorting apparatus mentioned above, and description is abbreviate | omitted.
[0060]
The waste transported to the waste discharge port by the vibration conveyor 1 is discharged from the waste discharge port while being loosened by the air flow ejected from the through hole 51 above the transport passage 12 before the waste discharge port.
[0061]
Then, the combustible material is blown upward by the air flow injected from the injection unit 42, and the non-combustible material that is heavier than the combustible material falls into the incombustible material container 47 in the foreground.
[0062]
At this time, although the lightweight aluminum can may be mixed among the incombustible materials in the combustible material that is blown upward, the mixed aluminum can falls onto the rake body 7. That is, the arrangement position of the body 7 that is easy to inject the air flow is set so that the aluminum can always falls on the rake body 7 no matter how much it is blown.
[0063]
Thus, the attitude of the aluminum can dropped on the rake body 7 is changed by the vibration transmitted from the vibrating conveyor 1 to the rake body 7, thereby falling from between the rods 72 to the incombustible material accommodating portion 47, and The fallen incombustible material is transported to a proper place by the transport conveyor 47a.
[0064]
The combustible material that has fallen on the scooping body 7 together with the aluminum can is conveyed to the front end side on the rod 72 by vibration of the scooping body 7, falls from the front end to the combustible material accommodating portion 49, and is directly guided by the guide plate 75. The combustible material that has fallen into the combustible material container 49 is transported to an appropriate place by the transport conveyor 49a.
[0065]
In this way, by receiving the aluminum can that has been blown upward by the scooping body 7 and guiding the aluminum can to the incombustible material accommodating portion 47a, it is possible to prevent the aluminum can from being mixed into the combustible material, and to improve the sorting accuracy. Can be planned.
[0066]
6 and 7 show the waste sorting apparatus according to the fourth aspect .
[0067]
This dust sorting apparatus is provided with a roller conveyor 8 instead of the above-described scoop body 7, and the other configurations are the same. Like members are denoted by the same reference numerals and description thereof is omitted.
[0068]
The roller conveyor 8 is composed of a plurality of rollers 81 disposed on the extension of the vibration conveyor 1 at a predetermined distance from the discharge end of the vibration conveyor 1.
[0069]
As shown in FIG. 7, both ends of these rollers 81 are pivotally supported in a state where the side surfaces of the recovery hopper forming the incombustible material accommodating portion 47 are inserted, and one end of these rollers 81 is connected via a sprocket 83 and a chain 84. It is configured to be freely driven by a drive motor 82 linked together.
[0070]
This roller 81 is a flanged roller having flanges 81c at both ends.
[0071]
The interval H between the rollers 81 is set such that an aluminum can can pass through and combustible materials are carried on the rollers 81 and conveyed.
[0072]
As shown in FIG. 8, the peripheral surface of the roller 81 is covered with an elastic body 81a such as rubber, and the elastic body 81a reduces the impact. A groove 81b is formed in the axial direction of the elastic body 81a. The groove 81b cuts the string-like material by passing a knife along the groove 81b when a string-like material such as lint is wound around the circumferential surface of the roller 81, that is, the surface of the elastic body 81a. Thus, the string-like material wound around the roller 81 can be easily removed.
[0073]
Further, a fixed blade 85 is disposed below each roller 81. The fixed blade 85 is to remove the string-like material or the plastic bag from the roller 81 when the string-like material or the plastic bag is entangled with each roller 81.
[0074]
Next, the operation of this dust sorting apparatus will be described.
[0075]
The waste transported to the waste discharge port by the vibration conveyor 1 is discharged from the waste discharge port while being loosened by the air flow ejected from the through hole 51 above the transport passage 12 before the waste discharge port.
[0076]
Then, the combustible material is blown upward by the air flow injected from the injection unit 42, and the non-combustible material that is heavier than the combustible material falls into the incombustible material container 47 in the foreground.
[0077]
At this time, although the lightweight aluminum can may be mixed among the noncombustible materials in the combustible material that is blown upward, the mixed aluminum can falls onto the roller conveyor 8. That is, the strength of the air flow to be jetted and the position of the roller conveyor 8 are set so that the aluminum can always falls on the roller conveyor 8 no matter how much it is blown.
[0078]
The aluminum cans that have fallen on the roller conveyor 8 are about to be conveyed by driving the roller conveyor 8, but the interval between the rollers 81 is set so that the aluminum can pass between them. It falls in the accommodating part 47, and is conveyed to an appropriate place by the conveyance conveyor 47a with the incombustible material which fell previously.
[0079]
The combustible material that has fallen on the roller conveyor 8 together with the aluminum can is conveyed by driving the roller conveyor 8, falls from the tip of the combustible material to the combustible material container 49, and directly falls to the combustible material container 49 by the guide plate 75. Together with the combustible material, it is transported to a proper place by a transport conveyor 49a.
[0080]
In this way, by receiving the aluminum cans that are blown upward by the roller conveyor 8 and guiding the aluminum cans to the incombustible material accommodating portion 47a, it is possible to prevent the aluminum cans from being mixed into the combustible materials and to improve the sorting accuracy. Can be planned.
[0081]
When a string-like object, a plastic bag, or the like is entangled with the roller 81 during the sorting operation described above, the string-like object, the plastic bag, or the like is removed by the fixed blade 85. Due to its structure, the removed string-like material or plastic bag falls into the incombustible material accommodating portion 47 and is mixed with the incombustible material. However, the incombustible material is further added to the iron can, the aluminum can, etc. in the later process. Since it is selected, there is no influence because it is selected in this selection process.
[0082]
On the other hand, when incombustible material is mixed into the combustible material, the selected combustible material is generally burned in the next process. During this combustion, the incombustible material melts and forms a side wall of the incinerator. To avoid adverse effects such as sticking, inflammables must be avoided from entering the combustible materials.
[0083]
That is, in the present invention, mixing of the aluminum can, which is an incombustible material, into the combustible material is prevented by the second sorting device such as the rake body 7 and the roller conveyor 8 described above.
[0084]
【The invention's effect】
As described above, according to the waste sorting device according to claim 1 of the present invention, the dust on the vibration conveyor charged each dust bag, the wind sorting device after breakage at breakage means on the vibrating conveyor Since the combustible material and the incombustible material are selected, the device can be made compact without separately providing a bag breaking device on the upstream side as in the prior art. In addition, the garbage broken by the vibration of the vibrating conveyor is loosened, and the dust can be further loosened by the air flow ejected from the through-hole provided in the transport passage. Can be planned. In addition, the bag breaking means can be reciprocated in the direction of the conveying path above the vibrating conveyor with a plurality of lower blades erected on the conveying path of the vibrating conveyor, and the tip portion approaches the conveying path. It is provided so as to be able to be separated, and can be pierced from above with a plurality of upper blades that can stab the trash bag by cooperating with the lower blade, and the upper blade is pierced into the trash bag. By moving the upper blade in the direction of the conveyance path, it is possible to reliably break the garbage bag in cooperation with the lower blade.
[0086]
According to the waste sorting apparatus according to claims 2 to 4, the second sorting apparatus such as a rake body or a roller conveyor can sort the combustible material and the aluminum can. Mixing of cans can be prevented, the accuracy of sorting can be improved, and incineration of combustible materials performed in the subsequent process is not adversely affected.
[0087]
According to the dust sorting apparatus according to claim 5, since the string-like material or the plastic bag entangled with the roller can be cut and removed by the fixed blade, the roller can always be driven smoothly and the sorting operation can be performed efficiently. It can be carried out.
[0088]
